DETAILED DESCRIPTION

[0058] A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.

[0059] Turning to FIG. 1A, the figure shows a system 100 for providing a paver block configuration with X-less joints.

[0060] More specifically, FIG. 1A shows a top plan view of a mold 110 for fabricating paver blocks (or blocks) 120 in a paver block layer 130 shown in FIG. 2B. As used herein a layer is a grouping of blocks 120 that are configured to be permanently set on a ground surface without extensive reorganization. As discussed in greater detail below, according to the embodiments, when multiple layers 130 are arranged on a ground, adjacent to each other, within and between the layers 130, the blocks 120 have joints that form an X- less joint pattern.

[0061] The mold 110 is generally formed so that in the plan view it is shaped as a quadrilateral, though other shapes are within the scope of the disclosure. The mold 110 extends in a first direction, longitudinally LI, between first (or upper ) end and second (or lower) end 150A, 150B to end walls 150A1, 150B1 by a longitudinal distance LID, and in a second direction, laterally L2, between first and second sides 160A, 160B to side walls 160A1, 160A2 by a lateral distance L2D.

[0062] As shown in FIG. 1A, the perimeter (or outer boundary) 180 of the mold 110, e.g., in a plan view, is rectangular. The distance LID between the ends 150A, 150B of the mold 110 is smaller than the distance L2D between the sides 160A, 160B by a ratio of three by four (3x4), i.e., having an aspect ratio of 4x3. The mold 110 extends heightwise from a bottom 170A to a top 170B to define a mold height MH.

[0063] With reference to FIG. 1A, the mold 110 has internal partition walls 190 that divide the mold 110 into cavities 200 that form the blocks 120. There are three (3) sizes of cavities 200, in the plan view of the mold 110.

[0064] The cavities include five (5) square block cavities (for brevity, SBCs), generally referenced as 210, including first through fifth SBCs 210A-210E, four of which are around the perimeter 180 and one is internal (spaced from the perimeter). For convenience, cavities are labeled in clockwise order, from a first corner 205 defined by the intersection of the first end 150A and the first side 160A, with cavities along the perimeter 180 labeled first followed by internal cavities. The SBCs 210 each have first and second side walls (or sides) 211A, 21 IB, each having a length L, so that the SBCs 210 have an L x L ratio in the plan view, defining a first cavity area. The value of the length L as referenced in each of the cavities 200 and blocks 120 is the same as each other.

[0065] The cavities 200 form five (5) small (or first) rectangular block cavities (for brevity, small-block cavities or SRBCs), generally referenced as 230, including first through fifth SRBCs 230A-230E, all of which are around the perimeter 180, each having half (0.5) of a surface area (plan view) of the SBCs 210. The SRBCs 230 each have first and second side walls (or sides) 231 A, 23 IB, with a first side that is a long side having a length L and a second side that is a short side having a length that is one-half (i.e., 0.5) L, such that the SRBCs 230 have a L x 0.5L ratio in the plan view, defining a second cavity area that is smaller than the first cavity area.

[0066] The SRBCs 230 are arranged as either longitudinally extending or laterally extending. A longitudinally extending SRBC (for brevity, a Long-SRBC) 232 is an SRBC 230 with its long side 231A extending in the longitudinal direction LI. A laterally extending SRBC (for brevity, a Lat-SRBC) 234 is an SRBC 230 with its long side 231A extending in the lateral direction L2. As shown in FIG. 1A, the second through fourth SRBCs 230B- 230D correspond with first through third Long-SRBCs 232A-232C. The first and fifth SRBCs 230A, 230E correspond with the first and second Lat-SRBCs 234A-234B.

[0067] The cavities 200 form three (3) large (or second) rectangular block cavities (for brevity, large-block cavities or LRBCs), generally referenced as 250, including first through third LRBCs 250A-250C, two of which are along the perimeter 180 and one is internal, each having one and a half (i.e., 1.5) times the surface area (plan view) of the SBCs 210. The LRBCs 250 each have first and second side walls (or sides) 251 A, 25 IB, with a first side that is a long side having a length that is one and a half (i.e., 1.5) times L and a second side that is a short side having a length that is L, such that the LRBCs 250 have a 1.5L x L ratio in the plan view, defining a third cavity area that is larger than the first cavity area.

[0068] The LRBCs 250 are arranged as either longitudinally extending or laterally extending. A longitudinally extending LRBC (for brevity, a Long-LRBC) 252 is an LRBC 250 with its long side 251A extending in the longitudinal direction LI. A laterally extending LRBC (for brevity, a Lat-LRBC) 254 is a LRBC with its long side 251 A extending in the lateral direction L2. As shown in FIG. 1A, the second and third LRBCs 250B, 250C correspond with first and second Long-LRBCs 252A, 252B and the first LRBC 250A corresponds with a first Lat-LRBC 254A.

[0069] Along the first end 150A of the mold 110, from the first side 160A to the second side 160B, the cavities 200 are arranged to provide the first Lat-SRBC 234A, the first Long-SRBC 232A, the first and second SBCs 210A, 210B, and the second Long-SRBC 232B. Along the second end 150B of the mold 110, from the second side 160B to the first side 160A, the cavities 200 arc arranged to provide the first Lat-LBRC 254A, the third Long- SRBC 232C, the second Lat-SRBC 234B, and the first Long-LRBC 252A.

[0070] The third SBC 210C is against the second side 160B, between the second Long-SRBC 232B and the first Lat-LRBC 254A. The fourth SBC 210D is against the first side 160A, between the first Lat-SRBC 234A and the first Long-LRBC 252A. The fifth SBC 210E is internal and is laterally against the third SBC 210C. The second Long-LRBC 252B is internal and is longitudinally against the second Lat-SRBC 234B.

[0071] The mold defines joints 275 between block cavities 200. As shown in the figure, with the configuration of the cavities 200 in the mold 110, the joints 275 define an X-less pattern. For example, the joints 275 define Ts.

[0072] Turning to FIG. IB, the layer 130 is configured so that, when it is printed from the mold 110, the size, shape, orientation and placement of the blocks 120 matches that of the cavities 200.

[0073] More specifically, the layer 130 in the plan view is generally defined as a quadrilateral, though other shapes are within the scope of the disclosure. The layer 130 extends in a first direction, longitudinally LI, between first (or upper ) end and second (or lower) end 35OA, 350B, and in a second direction, laterally L2, between first and second sides 360A, 360B.

[0074] As shown in FIG. IB, the perimeter 380 of the layer 130, e.g., in the plan view, is rectangular. The distance LID between the ends 350A, 350B of the layer 130 is smaller than the distance L2D between the sides 360A, 36OB by a ratio of three by four (3x4), i.e., forming an aspect ratio of 4x3. The layer 310 extends heightwise from a bottom 370A, which is positioned against a ground, to a top 370B to define a block height BH.

[0075] With reference to FIG. IB, there are three (3) sizes of blocks 120, in the plan view in the layer 130. The layer 130 includes five (5) square blocks (for brevity, SBs), generally referenced as 410, including first through fifth SB4s 410A-410E, four of which are around the perimeter 180 and one is internal (spaced from the perimeter). For convenience, cavities arc labeled in clockwise order, from the first corner 135 defined by the intersection of the first end 350A and the first side 360A, with blocks 120 along the perimeter 380 labeled first followed by internal blocks. The SBs 410 each have first and second sides 411A, 41 IB, each having a length L, so that the SBs 410 have an L x L ratio in the plan view and define a first block area.

[0076] The layer 130 has five (5) small (or first) rectangular blocks (for brevity, small-blocks or SRBs), generally referenced as 430, including first through fifth SRBs 430A-430E, each having half a surface area (plan view) of the SBs 410. The SRBs 430 each have a first and second sides 431 A, 43 IB, with a first side that is a long side having a length L and a second side that is a short side having a length that is one-half (i.e., 0.5) L, such that the SRBs 430 have a L x 0.5L ratio in the plan view, defining a second block area that is smaller than the first block area.

[0077] The SRBs 430 are arranged as either longitudinally extending or laterally extending. A longitudinally extending SRB (for brevity, a Long-SRB) 432 is an SRB 430 with its long side 431 A extending in the longitudinal direction LI. A laterally extending SRB (for brevity, a Lat-SRB) 434 is an SRB 430 with its long side 431 A extending in the lateral direction L2. As shown in FIG. IB, the second through fourth SRBs 430B-430D correspond with first through third Long-SRB s 432A-432C and the first and fifth SRBs 430A, 430E correspond with the first and second Lat-SRB s 434A-434B.

[0078] The layer 130 has three (3) large (or second) rectangular blocks (for brevity, large-blocks or LRBs), generally referenced as 450, including first through third LRBs 450A-450C, each having one and a half (i.e., 1.5) times the surface area (plan view) of the SBs 410. The LRBs 450 each have first and second sides 451A, 45 IB, with a first side that is a long side having a length that is one and a half (i.e., 1.5) times L and a second side that is a short side having a length that is L, such that the LRBs 450 have a 1.5L x L ratio in the plan view, defining a third block area that is larger than the first block area. [0079] The LRBs 450 are arranged as either longitudinally extending or laterally extending. A longitudinally extending LRB (for brevity, a Long-LRB) 452 is an LRB 450 with its long side 451 A extending in the longitudinal direction LI. A laterally extending LRB (for brevity, a Lat-LRB) 454 is a LRB with its long side 451 A extending in the lateral direction L2. As shown in FIG. IB, the second and third LRBs 450B, 450C correspond with first and second Long-LRB s 452A, 452B and the first LRB 450C corresponds with a first Lat-LRB 454A.

[0080] Along the first end 35OA of the layer 130, from the first side 360A to the second side 360B, the blocks 120 are arranged to provide the first Lat-SRB 434A, the first Long-SRB 432A, the first and second SBs 410A, 410B, and the second Long-SRB 432B. Along the second end 35OB of the layer 130, from the second side 360B to the first side 360A, the blocks 120 are arranged to provide the first Lat-LRB 434A, the third Long-SRB 432C, the second Lat-SRB 434B, and the first Long-LRB 452A.

[0081] The third SB 410C is against the second side 360B, between the second Long-SRB 432B and the first Lat-LRB 454A. The fourth SB 410D is against the first side 360A, between the first Lat-SRB 434A and the first Long-LRB 452A. The fifth SB 410E is internal and is laterally against the third SB 410C. The second Long-LRB 452B is internal and is longitudinally against the second Lat-SRB 434B.

[0082] The layer 130 defines joints 475 between the blocks. As shown in the figure, with the configuration of the blocks 120 in the layer 130, the joints 475 define an X-less pattern. For example, the joints 475 define Ts.

[0083] The above mold 110 provides joints between block cavities that are X-less, i.e., the joints define Ts. As such, the layer 130 provides blocks 120 that are arranged in an X-less joint configuration.

[0084] Turning to FIGS. 1C - IE, the figures show a method of laying two layers 130A, 130B of the type shown in FIG. IB, longitudinally adjacent to each other, to provide an X-less joint configuration for the layers. [0085] As shown in step S100 the method includes positioning two layers 130, including first and second layers 130A, 130B on a ground so that the first layer 130A is longitudinally above and laterally offset from the second layer 130B. Specifically, a lower end 35OB of the first layer 130A is against the upper end 350A of the second layer 130B. The first and second layers are laterally offset from each other by an offset distance OD1 equal to half (0.5) of L, e.g., between the first comer 135 of the second layer 130B and a second comer 136 of the first layer 130A. The second corner 136 is defined by an intersection of the first side 360A and the lower end 35OB. With this configuration, the second comer 136 of the first layer 130A terminates at a lateral midpoint LM of the first Lat-SRB 434A of the second layer 130B. With this configuration, the second Lat-SRB 434B of the first layer 130 and the first SB 410A of the second layer 130B are laterally aligned and longitudinally adjacent to each other. As shown in step SI 10, the method includes swapping the second Lat-SRB 434B of the first layer 130 and the first SB 410A of the second layer 130B with each other. The resulting configuration of the first and second layers 130A, 130B provides an X-less joint pattern as shown in FIG. ID.

[0086] FIG. IF shows an array 480 of layers 130 of FIG. IB built-out from the first and second layers 130A, 130B . The array 480 of layers 130 may be laid out over a driveway, roadway, patio, parking lot, park, or any area where pedestrians or automobiles may be located, stationary or moving, indoor or outdoor, as non-limiting examples. The same block swapping of FIG. IE occurs which each longitudinally adjacent ones of the layers 130 to provide an X-less join pattern throughout the array 480.

[0087] Turning to FIG. 2A, the figure shows another system 100 for providing a paver block configuration with X-less joints.

[0088] More specifically, FIG. 2A shows a top plan view of a mold 110 for fabricating paver blocks (or blocks) 120 in a paver block layer 130 shown in FIG. 2B. As used herein a layer is a grouping of blocks 120 that are configured to be permanently set on a ground surface without extensive reorganization. As discussed in greater detail below, according to the embodiments, when multiple layers 130 are arranged on a ground, adjacent to each other, within and between the layers 130, the blocks 120 have joints that form an X- less joint pattern.

[0089] The mold 110 is generally formed so that in the plan view it is shaped as a quadrilateral, though other shapes are within the scope of the disclosure. The mold 110 extends in a first direction, longitudinally LI, between first (or upper ) end and second (or lower) end 150A, 150B to end walls 150A1, 150B1 by a longitudinal distance LID, and in a second direction, laterally L2, between first and second sides 160A, 160B to side walls 160A1, 160A2 by a lateral distance L2D.

[0090] As shown in FIG. 2A, the perimeter (or outer boundary) 180 of the mold 110, e.g., in a plan view, is rectangular. The distance LID between the ends 150A, 150B of the mold 110 is smaller than the distance L2D between the sides 160A, 160B by a ratio of three by four (3x4), i.e., forming an aspect ratio of 4x3. The mold 110 extends heightwise from a bottom 170A to a top 170B to define a mold height MH.

[0091] With reference to FIG. 2A, the mold 110 has internal partition walls 190 that divide the mold 110 into cavities 200 that form the blocks 120. There are three (3) sizes of cavities 200, in the plan view of the mold 110.

[0092] The cavities include four (4) square block cavities (for brevity, SBCs), generally referenced as 210, including first through fourth SBCs 210A-210D, three of which are around the perimeter 180 and one is internal (spaced from the perimeter). For convenience, cavities are labeled in clockwise order, from a first corner 205 defined by the intersection of the first end 150A and the first side 160A, with cavities along the perimeter 180 labeled first followed by internal cavities. The SBCs 210 each have first and second side walls (or sides) 211A, 21 IB, each having a length L, so that the SBCs 210 have an L x L ratio in the plan view and define a first cavity area.

[0093] The value of the length L as referenced in each of the cavities 200 and blocks 120 is the same as each other. [0094] The cavities 200 form four (4) small (or first) rectangular block cavities (for brevity, small-block cavities or SRBCs), generally referenced as 230, including first through fourth SRBCs 230A-230D, all of which are around the perimeter 180, each having half (0.5) of a surface area (plan view) of the SBCs 210. The SRBCs 230 each have first and second side walls (or sides) 231 A, 23 IB, with a first side that is a long side having a length L and a second side that is a short side having a length that is one-half (i.e., 0.5) L, such that the SRBCs 230 have a L x 0.5L ratio in the plan view, defining a second cavity area that is smaller than the first cavity area.

[0095] The SRBCs 230 are arranged as either longitudinally extending or laterally extending. A longitudinally extending SRBC (for brevity, a Long-SRBC) 232 is an SRBC 230 with its long side 231A extending in the longitudinal direction LI. A laterally extending SRBC (for brevity, a Lat-SRBC) 234 is an SRBC 230 with its long side 231A extending in the lateral direction L2. As shown in FIG. 2A, the second and third SRBCs 230B-230C correspond with first and second Long-SRBCs 232A-232B. The first and fourth SRBCs 230A, 230D correspond with the first and second Lat-SRBCs 234A-234B.

[0096] The cavities 200 form four (4) large (or second) rectangular block cavities (for brevity, large-block cavities or LRBCs), generally referenced as 250, including first through fourth LRBCs 250A-250D, three of which are along the perimeter 180 and one is internal, each having one and a half (i.e., 1.5) times the surface area (plan view) of the SBCs 210. The LRBCs 250 each have first and second side walls (or sides) 251 A, 25 IB, with a first side that is a long side having a length that is one and a half (i.e., 1.5) times L and a second side that is a short side having a length that is L, such that the LRBCs 250 have a 1.5L x L ratio in the plan view, defining a third cavity area that is larger than the first cavity area.

[0097] The LRBCs 250 are arranged as either longitudinally extending or laterally extending. A longitudinally extending LRBC (for brevity, a Long-LRBC) 252 is an LRBC 250 with its long side 251A extending in the longitudinal direction LI. A laterally extending LRBC (for brevity, a Lat-LRBC) 254 is a LRBC with its long side 251 A extending in the lateral direction L2. As shown in FIG. 2A, the third and fourth LRBCs 250C, 250D correspond with first and second Long-LRBCs 252A, 252B and the first and second LRBCs 250A, 250B correspond with first and second Lat-LRBC 254A, 254B.

[0098] Along the first end 150A of the mold 110, from the first side 160A to the second side 160B, the cavities 200 are arranged to provide the first Lat-SRBC 234A, the first Long-SRBC 232A, the first SBC 210A, and the first Lat-LRBC 254B. Along the second end 150B of the mold 110, from the second side 160B to the first side 160A, the cavities 200 are arranged to provide the second Lat-LBRC 254B, the second Long-SRBC 232B, the second Lat-SRBC 234B, and the first Long-LRBC 252A.

[0099] The second SBC 210B is against the second side 160B, between the first and second Lat-LRBCs 254A, 254B. The third SBC 210C is against the first side 160A, between the first Lat-SRBC 234A and the first Long-LRBC 252A. The fourth SBC 210D is internal and is laterally against the second SBC 210B. The second Long-LRBC 252B is internal and is longitudinally against the second Lat-SRBC 234B.

[0100] The mold defines joints 275 between block cavities 200. As shown in the figure, with the configuration of the cavities 200 in the mold 110, the joints 275 define an X-less pattern. For example, the joints 275 define Ts.

[0101] Turning to FIG. 2B, the layer 130 is configured so that, when it is printed from the mold 110, the size, shape, orientation and placement of the blocks 120 matches that of the cavities 200.

[0102] More specifically, the layer 130 in the plan view is generally defined as a quadrilateral, though other shapes are within the scope of the disclosure. The layer 130 extends in a first direction, longitudinally LI, between first (or upper ) end and second (or lower) end 35OA, 350B, and in a second direction, laterally L2, between first and second sides 360A, 360B.

[0103] As shown in FIG. 2B, the perimeter 380 of the layer 130, e.g., in the plan view, is rectangular. The distance LID between the ends 350A, 350B of the layer 130 is smaller than the distance L2D between the sides 360 A, 36OB by a ratio of three by four (3x4), i.e., forming an aspect ratio of 4x3. The layer 310 extends heightwise from a bottom 370A, which is positioned against a ground, to a top 370B to define a block height BH.

[0104] With reference to FIG. 2B, there are three (3) sizes of blocks 120, in the plan view in the layer 130.

[0105] The layer 130 includes four (4) square blocks (for brevity, SBs), generally referenced as 410, including first through fourth SB4s 410A-410D three of which are around the perimeter 180 and one is internal (spaced from the perimeter). For convenience, cavities are labeled in clockwise order, from the first comer 135 defined by the intersection of the first end 350A and the first side 36OA, with blocks 120 along the perimeter 380 labeled first followed by internal blocks. The SBs 410 each have first and second sides 411A, 41 IB, each having a length L, so that the SBs 410 have an L x L ratio in the plan view and define a first block area.

[0106] The layer 130 has four (4) small (or first) rectangular blocks (for brevity, small-blocks or SRBs), generally referenced as 430, including first through fourth SRBs 430A-430D, each having half a surface area (plan view) of the SBs 410. The SRBs 430 each have a first and second sides 431 A, 43 IB, with a first side that is a long side having a length L and a second side that is a short side having a length that is one-half (i.e., 0.5) L, such that the SRBs 430 have a L x 0.5L ratio in the plan view, defining a second block area that is smaller than the first block area.

[0107] The SRBs 430 are arranged as either longitudinally extending or laterally extending. A longitudinally extending SRB (for brevity, a Long-SRB) 432 is an SRB 430 with its long side 431 A extending in the longitudinal direction LI. A laterally extending SRB (for brevity, a Lat-SRB) 434 is an SRB 430 with its long side 431 A extending in the lateral direction L2. As shown in FIG. 2B, the second and third SRBs 430B-430C correspond with first and second Long-SRB s 432A-432B and the first and fourth SRBs 430A, 430D correspond with the first and second Lat-SRB s 434A-434B. [0108] The layer 130 has four (4) large (or second) rectangular blocks (for brevity, large-blocks or LRBs), generally referenced as 450, including first through fourth LRBs 450A-450D, three of which are along the perimeter 180 and one is internal, each having one and a half (i.e., 1.5) times the surface area (plan view) of the SBs 410. The LRBs 450 each have first and second sides 451 A, 45 IB, with a first side that is a long side having a length that is one and a half (i.e., 1.5) times L and a second side that is a short side having a length that is L, such that the LRBs 450 have a 1.5L x L ratio in the plan view, defining a third block area that is larger than the first block area.

[0109] The LRBs 450 are arranged as either longitudinally extending or laterally extending. A longitudinally extending LRB (for brevity, a Long-LRB) 452 is an LRB 450 with its long side 451 A extending in the longitudinal direction LI. A laterally extending LRB (for brevity, a Lat-LRB) 454 is a LRB with its long side 451 A extending in the lateral direction L2. As shown in FIG. 2B, the third and fourth LRBs 450C, 450D correspond with first and second Long-LRBs 452A, 452B and the first and second LRBs 450A, 450B correspond with the first and second Lat-LRB s 454A, 454B.

[0110] Along the first end 35OA of the layer 130, from the first side 360A to the second side 360B, the blocks 120 are arranged to provide the first Lat-SRB 434A, the first Long-SRB 432A, the first SB 410A, and the first Lat-LRB 454A. Along the second end 350B of the layer 130, from the second side 360B to the first side 360A, the blocks 120 are arranged to provide the second Lat-LRB 454B, the second Long-SRB 432B, the second Lat- SRB 434B, and the first Long-LRB 452A.

[0111] The second SB 410B is against the second side 36OB, between the first and second Lat-LRB 454A, 454B. The third SB 410C is against the first side 36OA, between the first Lat-SRB 434A and the first Long-LRB 452A. The fourth SB 410D is internal and is laterally against the second SB 410B. The second Long-LRB 452B is internal and is longitudinally against the second Lat-SRB 434B. [0112] The layer 130 defines joints 475 between the blocks. As shown in the figure, with the configuration of the blocks 120 in the layer 130, the joints 475 define an X-lcss pattern. For example, the joints 475 define Ts.

[0113] The above mold 110 provides joints between block cavities that are X-less, i.e., the joints define Ts. As such, the layer 130 provides blocks 120 that are arranged in an X-less joint configuration.

[0114] Turning to FIGS. 2C - 2E, the figures show a method of laying two layers 130A, 130B of the type shown in FIG. 2B, longitudinally adjacent to each other, to provide an X-less joint configuration for the layers.

[0115] As shown in step S100 the method includes positioning two layers 130, including first and second layers 130A, 130B on a ground so that the first layer 130A is longitudinally above and laterally offset from the second layer 130B. Specifically, a lower end 35OB of the first layer 130A is against the upper end 350A of the second layer 130B. The first and second layers are laterally offset from each other by an offset distance OD1 equal to half (0.5) of L, e.g., between the first comer 135 of the second layer 130B and a second comer 136 of the first layer 130A. The second corner 136 is defined by an intersection of the first side 360A and the lower end 35OB. With this configuration, the second comer 136 of the first layer 130A terminates at a lateral midpoint LM of the first Lat-SRB 434A of the second layer 130B. The second Lat-SRB 434B of the first layer 130 and the first SB 410A of the second layer 130B are laterally aligned and longitudinally adjacent to each other. As shown in step SI 10, the method includes swapping the second Lat-SRB 434B of the first layer 130 and the first SB 410A of the second layer 130B with each other. The resulting configuration of the first and second layers 130A, 130B provides an X-less joint pattern as shown in FIG. 2D.

[0116] FIG. 2F shows an array 480 of layers 130 of FIG. 2B built-out from the first and second layers 130A, 130B . The array 480 of layers 130 may be laid out over a driveway, roadway, patio, parking lot, park, or any area where pedestrians or automobiles may be located, stationary or moving, indoor or outdoor. The same block swapping of FIG. 2E occurs which each longitudinally adjacent ones of the layers 130 to provide an X-less join pattern throughout the array 480.

[0117] Turning to FIG. 3A, the figure shows another system 100 for providing a paver block configuration with X-less joints.

[0118] More specifically, FIG. 3A shows a top plan view of a mold 110 for fabricating paver blocks (or blocks) 120 in a paver block layer 130 shown in FIG. 3B. As used herein a layer is a grouping of blocks 120 that are configured to be permanently set on a ground surface without extensive reorganization. As discussed in greater detail below, according to the embodiments, when multiple layers 130 are arranged on a ground, adjacent to each other, within and between the layers 130, the blocks 120 have joints that form an X- less joint pattern.

[0119] The mold 110 is generally formed so that in the plan view it is shaped as a quadrilateral, though other shapes are within the scope of the disclosure. The mold 110 extends in a first direction, longitudinally LI, between first (or upper ) end and second (or lower) end 150A, 150B to end walls 150A1, 150B1 by a longitudinal distance LID, and in a second direction, laterally L2, between first and second sides 160A, 160B to side walls 160A1, 160A2 by a lateral distance L2D.

[0120] As shown in FIG. 3A, the perimeter (or outer boundary) 180 of the mold 110, e.g., in a plan view, is rectangular. The distance LID between the ends 150A, 150B of the mold 110 is smaller than the distance L2D between the sides 160A, 160B by a ratio of three to three and a half (3 x 3.5), i.e., forming an aspect ratio of 3.5x3. The mold 110 extends heightwise from a bottom 170A to a top 170B to define a mold height MH.

[0121 ] With reference to FIG. 3 A, the mold 1 10 has internal partition walls 190 that divide the mold 110 into cavities 200 that form the blocks 120. There are three (3) sizes of cavities 200, in the plan view of the mold 110.

[0122] The cavities include four (4) square block cavities (for brevity, SBCs), generally referenced as 210, including first through fourth SBCs 210A-210D, three of which are around the perimeter 180 and one is internal (spaced from the perimeter). For convenience, cavities arc labeled in clockwise order, from a first corner 205 defined by the intersection of the first end 150A and the first side 160A, with cavities along the perimeter 180 labeled first followed by internal cavities. The SBCs 210 each have first and second side walls (or sides) 211A, 21 IB, each having a length L, so that the SBCs 210 have an L x L ratio in the plan view and define a first cavity area.

[0123] The value of the length L as referenced in each of the cavities 200 and blocks 120 is the same as each other.

[0124] The cavities 200 form four (4) small (or first) rectangular block (cavities (for brevity, small-block cavities or SRBCs), generally referenced as 230, including first through fourth SRBCs 230A-230D, all of which are around the perimeter 180, each having half (0.5) of a surface area (plan view) of the SBCs 210. The SRBCs 230 each have first and second side walls (or sides) 231 A, 23 IB, with a first side that is a long side having a length L and a second side that is a short side having a length that is one-half (i.e., 0.5) L, such that the SRBCs 230 have a L x 0.5L ratio in the plan view, defining a second block area that is smaller than the first block area.

[0125] The SRBCs 230 are arranged as either longitudinally extending or laterally extending. A longitudinally extending SRBC (for brevity, a Long-SRBC) 232 is an SRBC 230 with its long side 231A extending in the longitudinal direction LI. A laterally extending SRBC (for brevity, a Lat-SRBC) 234 is an SRBC 230 with its long side 231A extending in the lateral direction L2. As shown in FIG. 3A, the second and third SRBCs 230B-230C correspond with first and second Long-SRBCs 232A-232B. The first and fourth SRBCs 230A, 230D correspond with the first and second Lat-SRBCs 234A-234B.

[0126] The cavities 200 form three (3) large (or second) rectangular block cavities (for brevity, large-block cavities or LRBCs), generally referenced as 250, including first through third LRBCs 250A-250C, two of which are along the perimeter 180 and one is internal, each having one and a half (i.e., 1.5) times the surface area (plan view) of the SBCs 210. The LRBCs 250 each have first and second side walls (or sides) 251 A, 25 IB, with a first side that is a long side having a length that is one and a half (i.e., 1.5) times L and a second side that is a short side having a length that is L, such that the LRBCs 250 have a 1.5L x L ratio in the plan view, defining a third cavity area that is larger than the first cavity area.

[0127 J The LRBCs 250 are arranged as either longitudinally extending or laterally extending. A longitudinally extending LRBC (for brevity, a Long-LRBC) 252 is an LRBC 250 with its long side 251A extending in the longitudinal direction LI. A laterally extending LRBC (for brevity, a Lat-LRBC) 254 is a LRBC with its long side 251 A extending in the lateral direction L2. As shown in FIG. 3A, the second and third LRBCs 250B, 250C correspond with first and second Long-LRBCs 252A, 252B and the first LRBC 250A corresponds with first Lat-LRBC 254A.

[0128] Along the first end 150A of the mold 110, from the first side 160A to the second side 160B, the cavities 200 are arranged to provide the first Lat-SRBC 234A, the first Long-SRBC 232A, and the first and second SBCs 210A, 210B. Along the second end 150B of the mold 110, from the second side 160B to the first side 160A, the cavities 200 are arranged to provide the first Lat-LBRC 254A, the second Lat-SRBC 234B, and the first Long-LRBC 252A.

[0129] The second Long-SRBC 232B is against the second side 160B, between the second SBC 210B and the first Lat-LRBC 254A. The third SBC 210C is against the first side 160A, between the first Lat-SRBC 234A and the first Long-LRBC 252A. The fourth SBC 210D is internal and is laterally against the second Long-SRBC 232B. The second Long-LRBC 252B is internal and is longitudinally against the second Lat-SRBC 234B.

[0130] The mold defines joints 275 between block cavities 200. As shown in the figure, with the configuration of the cavities 200 in the mold 110, the joints 275 define an X-less pattern. For example, the joints 275 define Ts. [0131] Turning to FIG. 3B, the layer 130 is configured so that, when it is printed from the mold 110, the size, shape, orientation and placement of the blocks 120 matches that of the cavities 200.

[0132] More specifically, the layer 130 in the plan view is generally defined as a quadrilateral, though other shapes are within the scope of the disclosure. The layer 130 extends in a first direction, longitudinally LI, between first (or upper ) end and second (or lower) end 35OA, 350B, and in a second direction, laterally L2, between first and second sides 360A, 360B.

[0133] As shown in FIG. 3B, the perimeter 380 of the layer 130, e.g., in the plan view, is rectangular. The distance LID between the ends 350A, 350B of the layer 130 is smaller than the distance L2D between the sides 360 A, 36OB by a ratio of three by four (3x4), i.e., forming an aspect ratio of 4x3. The layer 310 extends heightwise from a bottom 370A, which is positioned against a ground, to a top 370B to define a block height BH.

[0134] With reference to FIG. 3B, there are three (3) sizes of blocks 120, in the plan view in the layer 130.

[0135] The layer 130 includes four (4) square blocks (for brevity, SBs), generally referenced as 410, including first through fourth SB4s 410A-410D three of which are around the perimeter 180 and one is internal (spaced from the perimeter). For convenience, cavities are labeled in clockwise order, from the first comer 135 defined by the intersection of the first end 350A and the first side 36OA, with blocks 120 along the perimeter 380 labeled first followed by internal blocks. The SBs 410 each have first and second sides 411A, 41 IB, each having a length L, so that the SBs 410 have an L x L ratio in the plan view and define a first block area.

[0136] The layer 130 has four (4) small (or first) rectangular blocks (for brevity, small-blocks or SRBs), generally referenced as 430, including first through fourth SRBs 430A-430D, each having half a surface area (plan view) of the SBs 410. The SRBs 430 each have a first and second sides 431 A, 43 IB, with a first side that is a long side having a length L and a second side that is a short side having a length that is one-half (i.e., 0.5) L, such that the SRBs 430 have a L x 0.5L ratio in the plan view, defining a second block area that is smaller than the first block area.

[0137] The SRBs 430 are arranged as either longitudinally extending or laterally extending. A longitudinally extending SRB (for brevity, a Long-SRB) 432 is an SRB 430 with its long side 431 A extending in the longitudinal direction LI. A laterally extending SRB (for brevity, a Lat-SRB) 434 is an SRB 430 with its long side 431 A extending in the lateral direction L2. As shown in FIG. 3B, the second and third SRBs 430B-430C correspond with first and second Long-SRB s 432A-432B and the first and fourth SRBs 430A, 430D correspond with the first and second Lat-SRB s 434A-434B.

[0138] The layer 130 has three (3) large (or second) rectangular blocks (for brevity, large-blocks or LRBs), generally referenced as 450, including first through third LRBs 450A-450C, two of which are along the perimeter 180 and one is internal, each having one and a half (i.e., 1.5) times the surface area (plan view) of the SBs 410. The LRBs 450 each have first and second sides 451 A, 45 IB, with a first side that is a long side having a length that is one and a half (i.e., 1.5) times L and a second side that is a short side having a length that is L, such that the LRBs 450 have a 1.5L x L ratio in the plan view, defining a third block area that is larger than the first block area.

[0139] The LRBs 450 are arranged as either longitudinally extending or laterally extending. A longitudinally extending LRB (for brevity, a Long-LRB) 452 is an LRB 450 with its long side 451 A extending in the longitudinal direction LI. A laterally extending LRB (for brevity, a Lat-LRB) 454 is a LRB with its long side 451 A extending in the lateral direction L2. As shown in FIG. 3B, the third and fourth LRBs 450C, 450D correspond with first and second Long-LRB s 452A, 452B and the first LRB 450A corresponds with the first Lat-LRB 454A.

[0140] Along the first end 35OA of the layer 130, from the first side 360A to the second side 360B, the blocks 120 are arranged to provide the first Lat-SRB 434A, the first Long-SRB 432A, and the first and second SBs 410A, 410B. Along the second end 35OB of the layer 130, from the second side 360B to the first side 360A, the blocks 120 are arranged to provide the first Lat-LRB 454A, the second Lat-SRB 434B, and the first Long-LRB 452A.

[0141] The second Long-SRB 432B is against the second side 36OB, between the second SB 410B and the first Lat-LRB 454A. The third SB 410C is against the first side 360A, between the first Lat-SRB 434A and the first Long-LRB 452A. The fourth SB 410D is internal and is laterally against the second Long-SRB 432B. The second Long-LRB 452B is internal and is longitudinally against the second Lat-SRB 434B.

[0142] The layer 130 defines joints 475 between the blocks. As shown in the figure, with the configuration of the blocks 120 in the layer 130, the joints 475 define an X-less pattern. For example, the joints 475 define Ts.

[0143] The above mold 110 provides joints between block cavities that are X-less, i.e., the joints define Ts. As such, the layer 130 provides blocks 120 that are arranged in an X-less joint configuration.

[0144] Turning to FIGS. 3C - 3E, the figures show a method of laying two layers 130A, 130B of the type shown in FIG. 3B, longitudinally adjacent to each other, to provide an X-less joint configuration for the layers.

[0145] As shown in step S100 the method includes positioning two layers 130, including first and second layers 130A, 130B on a ground so that the first layer 130A is longitudinally above and laterally offset from the second layer 130B. Specifically, a lower end 35OB of the first layer 130A is against the upper end 350A of the second layer 130B. The first and second layers are laterally offset from each other by an offset distance OD1 equal to half (0.5) of L, e.g., between the first comer 135 of the second layer 130B and a second comer 136 of the first layer 130A. The second corner 136 is defined by an intersection of the first side 360A and the lower end 35OB. With this configuration, the second comer 136 of the first layer 130A terminates at a lateral midpoint LM of the first Lat-SRB 434A of the second layer 130B. The second Lat-SRB 434B of the first layer 130 and the first SB 410A of the second layer 130B are laterally aligned and longitudinally adjacent to each other. As shown in step SI 10, the method includes swapping the second Lat-SRB 434B of the first layer 130 and the first SB 410A of the second layer 130B with each other. The resulting configuration of the first and second layers 130A, 130B provides an X-less joint pattern as shown in FIG. 3D.

[0146] FIG. 3F shows an array 480 of layers 130 of FIG. 3B built-out from the first and second layers 130A, 130B . The array 480 of layers 130 may be laid out over a driveway, roadway, patio, parking lot, park, or any area where pedestrians or automobiles may be located, stationary or moving, indoor or outdoor. The same block swapping of FIG. 3E occurs which each longitudinally adjacent ones of the layers 130 to provide an X-less join pattern throughout the array 480.

[0147] Turning to FIG. 4A, the figure shows another system 100 for providing a paver block configuration with X-less joints.

[0148] More specifically, FIG. 4A shows a top plan view of a mold 110 for fabricating paver blocks (or blocks) 120 in a paver block layer 130 shown in FIG. 4B. As used herein a layer is a grouping of blocks 120 that are configured to be permanently set on a ground surface without extensive reorganization. As discussed in greater detail below, according to the embodiments, when multiple layers 130 arc arranged on a ground, adjacent to each other, within and between the layers 130, the blocks 120 have joints that form an X- less joint pattern.

[0149] The mold 110 is generally formed so that in the plan view it is shaped as a quadrilateral, though other shapes are within the scope of the disclosure. The mold 110 extends in a first direction, longitudinally LI, between first (or upper ) end and second (or lower) end 150A, 150B to end walls 150A1, 150B1 by a longitudinal distance LID, and in a second direction, laterally L2, between first and second sides 160A, 160B to side walls 160A1, 160A2 by a lateral distance L2D. [0150] As shown in FIG. 4A, the perimeter (or outer boundary) 180 of the mold 110, c.g., in a plan view, is rectangular. The distance LID between the ends 150A, 150B of the mold 110 is smaller than the distance L2D between the sides 160A, 160B by a ratio of three to three and a half (3 x 3.5), i.e., forming an aspect ratio of 3.5x3. The mold 110 extends heightwise from a bottom 170A to a top 170B to define a mold height MH.

[0151] With reference to FIG. 4A, the mold 110 has internal partition walls 190 that divide the mold 110 into cavities 200 that form the blocks 120. There are three (3) sizes of cavities 200, in the plan view of the mold 110.

[0152] The cavities include five (5) square block cavities (for brevity, SBCs), generally referenced as 210, including first through fifth SBCs 210A-210E, four of which are around the perimeter 180 and one is internal (spaced from the perimeter). For convenience, cavities are labeled in clockwise order, from a first corner 205 defined by the intersection of the first end 150A and the first side 160A, with cavities along the perimeter 180 labeled first followed by internal cavities. The SBCs 210 each have first and second side walls (or sides) 211A, 21 IB, each having a length L, so that the SBCs 210 have an L x L ratio in the plan view and define a first cavity area.

[0153] The value of the length L as referenced in each of the cavities 200 and blocks 120 is the same as each other.

[0154] The cavities 200 form five (5) small (or first) rectangular block cavities (for brevity, small-block cavities or SRBCs), generally referenced as 230, including first through fifth SRBCs 230A-230E, all of which are around the perimeter 180, each having half (0.5) of a surface area (plan view) of the SBCs 210. The SRBCs 230 each have first and second side walls (or sides) 231 A, 23 IB, with a first side that is a long side having a length L and a second side that is a short side having a length that is one-half (i.e., 0.5) L, such that the SRBCs 230 have a L x 0.5L ratio in the plan view, defining a second cavity area that is smaller than the first cavity area.

T1 [0155] The SRBCs 230 are arranged as either longitudinally extending or laterally extending. A longitudinally extending SRBC (for brevity, a Long-SRBC) 232 is an SRBC 230 with its long side 231A extending in the longitudinal direction LI. A laterally extending SRBC (for brevity, a Lat-SRBC) 234 is an SRBC 230 with its long side 231A extending in the lateral direction L2. As shown in FIG. 4A, the second through fourth SRBCs 230B- 230D correspond with first through third Long-SRBCs 232A-232C. The first and fifth SRBCs 230A, 230E correspond with the first and second Lat-SRBCs 234A-234B.

[0156] The cavities 200 form two (2) large (or second) rectangular block cavities (for brevity, large-block cavities or LRBCs), generally referenced as 250, including first and second LRBCs 250A-250B, one of which is along the perimeter 180 and one is internal, each having one and a half (i.e., 1.5) times the surface area (plan view) of the SBCs 210. The LRBCs 250 each have first and second side walls (or sides) 251 A, 25 IB, with a first side that is a long side having a length that is one and a half (i.e., 1.5) times L and a second side that is a short side having a length that is L, such that the LRBCs 250 have a 1.5L x L ratio in the plan view, defining a third cavity area that is larger than the first cavity area.

[0157] The LRBCs 250 are arranged as either longitudinally extending or laterally extending. A longitudinally extending LRBC (for brevity, a Long-LRBC) 252 is an LRBC 250 with its long side 251A extending in the longitudinal direction LI. A laterally extending LRBC (for brevity, a Lat-LRBC) 254 is a LRBC with its long side 251 A extending in the lateral direction L2. As shown in FIG. 4A, the first and second LRBCs 250A, 250B correspond with first and second Long-LRBCs 252A, 252B.

[0158] Along the first end 150A of the mold 110, from the first side 160A to the second side 160B, the cavities 200 are arranged to provide the first Lat-SRBC 234A, the first Long-SRBC 232A, and the first and second SBCs 210A, 210B. Along the second end 150B of the mold 110, from the second side 160B to the first side 160A, the cavities 200 are arranged to provide the third SBC 210C, the third Long-SBRC 232C, the second Lat- SRBC 234B, and the first Long-LRBC 252A. [0159] The second Long-SRBC 232B is against the second side 160B, between the second and third SBCs 210B, 210C. The fourth SBC 210D is against the first side 160A, between the first Lat-SRBC 234A and the first Long-LRBC 252A. The fifth SBC 210E is internal and is laterally against the second Long-SRBC 232B. The second Long-LRBC 252B is internal and is longitudinally against the second Lat-SRBC 234B.

[0160] The mold defines joints 275 between block cavities 200. As shown in the figure, with the configuration of the cavities 200 in the mold 110, the joints 275 define an X-less pattern. For example, the joints 275 define Ts.

[0161] Turning to FIG. 4B, the layer 130 is configured so that, when it is printed from the mold 110, the size, shape, orientation and placement of the blocks 120 matches that of the cavities 200.

[0162] More specifically, the layer 130 in the plan view is generally defined as a quadrilateral, though other shapes are within the scope of the disclosure. The layer 130 extends in a first direction, longitudinally LI, between first (or upper ) end and second (or lower) end 35OA, 350B, and in a second direction, laterally L2, between first and second sides 360A, 360B.

[0163] As shown in FIG. 4B, the perimeter 380 of the layer 130, e.g., in the plan view, is rectangular. The distance LID between the ends 350A, 350B of the layer 130 is smaller than the distance L2D between the sides 360 A, 36OB by a ratio of three by four (3x4), i.e., having an aspect ratio of 4x3. The layer 310 extends heightwise from a bottom 370A, which is positioned against a ground, to a top 370B to define a block height BH.

[0164] With reference to FIG. 4B, there are three (3) sizes of blocks 120, in the plan view in the layer 130.

[0165] The layer 130 includes five (5) square blocks (for brevity, SBs), generally referenced as 410, including first through fifth SB4s 410A-410E, four of which are around the perimeter 180 and one is internal (spaced from the perimeter). For convenience, cavities are labeled in clockwise order, from the first comer 135 defined by the intersection of the first end 350A and the first side 36OA, with blocks 120 along the perimeter 380 labeled first followed by internal blocks. The SBs 410 each have first and second sides 411A, 41 IB, each having a length L, so that the SBs 410 have an L x L ratio in the plan view and define a first block area.

[0166] The layer 130 has five (5) small (or first) rectangular blocks (for brevity, small-blocks or SRBs), generally referenced as 430, including first through fifth SRBs 430A-430E, each having half a surface area (plan view) of the SBs 410. The SRBs 430 each have a first and second sides 431 A, 43 IB, with a first side that is a long side having a length L and a second side that is a short side having a length that is one-half (i.e., 0.5) L, such that the SRBs 430 have a L x 0.5L ratio in the plan view, defining a second block area that is smaller than the first block area.

[0167] The SRBs 430 are arranged as either longitudinally extending or laterally extending. A longitudinally extending SRB (for brevity, a Long-SRB) 432 is an SRB 430 with its long side 431 A extending in the longitudinal direction LI. A laterally extending SRB (for brevity, a Lat-SRB) 434 is an SRB 430 with its long side 431 A extending in the lateral direction L2. As shown in FIG. 4B, the second through fourth SRBs 430B-430D correspond with first through third Long-SRB s 432A-432C and the first and fifth SRBs 430A, 430E correspond with the first and second Lat-SRB s 434A-434B.

[0168] The layer 130 has two (2) large (or second) rectangular blocks (for brevity, large-blocks or LRBs), generally referenced as 450, including first and second LRBs 450A- 450B, one of which is along the perimeter 180 and one is internal, each having one and a half (i.e., 1.5) times the surface area (plan view) of the SBs 410. The LRBs 450 each have first and second sides 451 A, 45 IB, with a first side that is a long side having a length that is one and a half (i.e., 1.5) times L and a second side that is a short side having a length that is L, such that the LRBs 450 have a 1.5L x L ratio in the plan view, defining a third block area that is larger than the first block area.

[0169] The LRBs 450 are arranged as either longitudinally extending or laterally extending. A longitudinally extending LRB (for brevity, a Long-LRB) 452 is an LRB 450 with its long side 451 A extending in the longitudinal direction LI. A laterally extending LRB (for brevity, a Lat-LRB) 454 is a LRB with its long side 451 A extending in the lateral direction L2. As shown in FIG. 4B, the first and second LRBs 450A, 450B correspond with first and second Long-LRBs 452A, 452B.

[0170] Along the first end 35OA of the layer 130, from the first side 360A to the second side 360B, the blocks 120 are arranged to provide the first Lat-SRB 434A, the first Long-SRB 432A, and the first and second SBs 410A, 410B. Along the second end 35OB of the layer 130, from the second side 360B to the first side 360A, the blocks 120 are arranged to provide the third SB 210C, the third Long-SRB 432C, the second Lat-SRB 434B, and the first Long-LRB 452A.

[0171] The second Long-SRB 432B is against the second side 36OB, between the second and third SBs 410B, 410C. The fourth SB 410D is against the first side 36OA, between the first Lat-SRB 434A and the first Long-LRB 452A. The fifth SB 410E is internal and is laterally against the second Long-SRB 432B. The second Long-LRB 452B is internal and is longitudinally against the second Lat-SRB 434B.

[0172] The layer 130 defines joints 475 between the blocks. As shown in the figure, with the configuration of the blocks 120 in the layer 130, the joints 475 define an X-less pattern. For example, the joints 475 define Ts.

[0173] The above mold 110 provides joints between block cavities that are X-less, i.e., the joints define Ts. As such, the layer 130 provides blocks 120 that are arranged in an X-less joint configuration.

[0174] Turning to FIGS. 4C - 4E, the figures show a method of laying two layers 1 0A, 130B of the type shown in FIG. 4B, longitudinally adjacent to each other, to provide an X-less joint configuration for the layers.

[0175] As shown in step S100 the method includes positioning two layers 130, including first and second layers 130A, 130B on a ground so that the first layer 130A is longitudinally above and laterally offset from the second layer 130B. Specifically, a lower end 35OB of the first layer 130A is against the upper end 350A of the second layer 130B. The first and second layers arc laterally offset from each other by an offset distance OD1 equal to half (0.5) of L, e.g., between the first comer 135 of the second layer 130B and a second comer 136 of the first layer 130A. The second corner 136 is defined by an intersection of the first side 360A and the lower end 35OB. With this configuration, the second comer 136 of the first layer 130A terminates at a lateral midpoint LM of the first Lat-SRB 434A of the second layer 130B. The second Lat-SRB 434B of the first layer 130 and the first SB 410A of the second layer 130B are laterally aligned and longitudinally adjacent to each other. As shown in step SI 10, the method includes swapping the second Lat-SRB 434B of the first layer 130 and the first SB 410A of the second layer 130B with each other. The resulting configuration of the first and second layers 130A, 130B provides an X-less joint pattern as shown in FIG. 4D.

[0176] FIG. 4F shows an array 480 of layers 130 of FIG. 4B built-out from the first and second layers 130A, 130B . The array 480 of layers 130 may be laid out over a driveway, roadway, patio, parking lot, park, or any area where pedestrians or automobiles may be located, stationary or moving, indoor or outdoor. The same block swapping of FIG. 4E occurs which each longitudinally adjacent ones of the layers 130 to provide an X-less join pattern throughout the array 480.

[0177] Turning to FIG. 5A, the figure shows another system 100 for providing a paver block configuration with X-less joints.

[0178] More specifically, FIG. 5A shows a top plan view of a mold 110 for fabricating paver blocks (or blocks) 120 in a paver block layer 130 shown in FIG. 5B. As used herein a layer is a grouping of blocks 120 that are configured to be permanently set on a ground surface without extensive reorganization. As discussed in greater detail below, according to the embodiments, when multiple layers 130 are arranged on a ground, adjacent to each other, within and between the layers 130, the blocks 120 have joints that form an X- less joint pattern. [0179] The mold 110 is generally formed so that in the plan view it is shaped as a quadrilateral, though other shapes arc within the scope of the disclosure. The mold 110 extends in a first direction, longitudinally LI, between first (or upper ) end and second (or lower) end 150A, 150B to end walls 150A1, 150B1 by a longitudinal distance LID, and in a second direction, laterally L2, between first and second sides 160A, 160B to side walls 160A1, 160A2 by a lateral distance L2D.

[0180] As shown in FIG. 5 A, the perimeter (or outer boundary) 180 of the mold 110, e.g., in a plan view, is rectangular. The distance LID between the ends 150A, 150B of the mold 110 is smaller than the distance L2D between the sides 160A, 160B by a ratio of three to three and a half (3 x 3.5), i.e., forming an aspect ratio of 3.5x3. The mold 110 extends heightwise from a bottom 170A to a top 170B to define a mold height MH.

[0181] With reference to FIG. 5 A, the mold 110 has internal partition walls 190 that divide the mold 110 into cavities 200 that form the blocks 120. There are three (3) sizes of cavities 200, in the plan view of the mold 110.

[0182] The cavities include four (4) square block cavities (for brevity, SBCs), generally referenced as 210, including first through fourth SBCs 210A-210D, each of which are around the perimeter 180, i.e., none is internal (spaced from the perimeter). For convenience, cavities arc labeled in clockwise order, from a first corner 205 defined by the intersection of the first end 150A and the first side 160A, with cavities along the perimeter 180 labeled first followed by internal cavities. The SBCs 210 each have first and second side walls (or sides) 211A, 21 IB, each having a length L, so that the SBCs 210 have an L x L ratio in the plan view and define a first cavity area. The value of the length L as referenced in each of the cavities 200 and blocks 120 is the same as each other.

[0183] The cavities 200 form four (4) small (or first) rectangular block cavities (for brevity, small-block cavities or SRBCs), generally referenced as 230, including first through fourth SRBCs 230A-230D, all of which are around the perimeter 180, each having half (0.5) of a surface area (plan view) of the SBCs 210. The SRBCs 230 each have first and second side walls (or sides) 231 A, 23 IB, with a first side that is a long side having a length L and a second side that is a short side having a length that is one-half (i.e., 0.5) L, such that the SRBCs 230 have a L x 0.5L ratio in the plan view, defining a second cavity area that is smaller than the first cavity area.

[0184] The SRBCs 230 are arranged as either longitudinally extending or laterally extending. A longitudinally extending SRBC (for brevity, a Long-SRBC) 232 is an SRBC 230 with its long side 231A extending in the longitudinal direction LI. A laterally extending SRBC (for brevity, a Lat-SRBC) 234 is an SRBC 230 with its long side 231A extending in the lateral direction L2. As shown in FIG. 5A, the second and third SRBCs 230B-230C correspond with first and second Long-SRBCs 232A-232B. The first and fourth SRBCs 230A, 230D correspond with the first and second Lat-SRBCs 234A-234B.

[0185] The cavities 200 form three (3) large (or second) rectangular block cavities (for brevity, large-block cavities or LRBCs), generally referenced as 250, including first through third LRBCs 250A-250C, two of which are along the perimeter 180 and one is internal, each having one and a half (i.e., 1.5) times the surface area (plan view) of the SBCs 210. The LRBCs 250 each have first and second side walls (or sides) 251 A, 25 IB, with a first side that is a long side having a length that is one and a half (i.e., 1.5) times L and a second side that is a short side having a length that is L, such that the LRBCs 250 have a 1.5L x L ratio in the plan view, defining a third cavity area that is larger than the first cavity area.

[0186] The LRBCs 250 are arranged as either longitudinally extending or laterally extending. A longitudinally extending LRBC (for brevity, a Long-LRBC) 252 is an LRBC 250 with its long side 251A extending in the longitudinal direction LI. A laterally extending LRBC (for brevity, a Lat-LRBC) 254 is a LRBC with its long side 251 A extending in the lateral direction L2. As shown in FIG. 5A, the second and third LRBCs 250B, 250C correspond with first and second Long-LRBCs 252A, 252B and the first LRBC 250A corresponds with the first Lat-LRBC 254A.

[0187] Along the first end 150A of the mold 110, from the first side 160A to the second side 160B, the cavities 200 are arranged to provide the first Lat-SRBC 234A, the first Long-SRBC 232A, and the first and second SBCs 210A, 210B. Along the second end 150B of the mold 110, from the second side 160B to the first side 160A, the cavities 200 are arranged to provide the third SBC 210C, the second Long-SBRC 232B, the second Lat- SRBC 234B, and the first Long-LRBC 252A.

[0188] The first Lat-LRBC 254B is against the second side 160B, between the second and third SBCs 210B, 210C. The fourth SBC 210D is against the first side 160A, between the first Lat-SRBC 234A and the first Long-LRBC 252A. The second Long-LRBC 252B is internal and is longitudinally against the second Lat-SRBC 234B.

[0189] The mold defines joints 275 between block cavities 200. As shown in the figure, with the configuration of the cavities 200 in the mold 110, the joints 275 define an X-less pattern. For example, the joints 275 define Ts.

[0190] Turning to FIG. 5B, the layer 130 is configured so that, when it is printed from the mold 110, the size, shape, orientation and placement of the blocks 120 matches that of the cavities 200.

[0191] More specifically, the layer 130 in the plan view is generally defined as a quadrilateral, though other shapes are within the scope of the disclosure. The layer 130 extends in a first direction, longitudinally LI, between first (or upper ) end and second (or lower) end 35OA, 350B, and in a second direction, laterally L2, between first and second sides 360A, 360B.

[0192] As shown in FIG. 5B, the perimeter 380 of the layer 130, e.g., in the plan view, is rectangular. The distance LID between the ends 350A, 350B of the layer 130 is smaller than the distance L2D between the sides 360 A, 36OB by a ratio of three by four (3x4), i.e., forming an aspect ratio of 4x3. The layer 10 extends heightwise from a bottom 370A, which is positioned against a ground, to a top 370B to define a block height BH.

[0193] With reference to FIG. 5B, there are three (3) sizes of blocks 120, in the plan view in the layer 130. [0194] The layer 130 includes four (4) square blocks (for brevity, SBs), generally referenced as 410, including first through fourth SB4s 410A-410D, each of which arc around the perimeter 180, i.e., none is internal (spaced from the perimeter). For convenience, cavities are labeled in clockwise order, from the first corner 135 defined by the intersection of the first end 350A and the first side 360A, with blocks 120 along the perimeter 380 labeled first followed by internal blocks. The SBs 410 each have first and second sides 411A, 41 IB, each having a length L, so that the SBs 410 have an L x L ratio in the plan view and define a first block area.

[0195] The layer 130 has four (4) small (or first) rectangular blocks (for brevity, small-blocks or SRBs), generally referenced as 430, including first through fourth SRBs 430A-430D, each having half a surface area (plan view) of the SBs 410. The SRBs 430 each have a first and second sides 431 A, 43 IB, with a first side that is a long side having a length L and a second side that is a short side having a length that is one-half (i.e., 0.5) L, such that the SRBs 430 have a L x 0.5L ratio in the plan view, defining a second block area that is smaller than the first block area.

[0196] The SRBs 430 are arranged as either longitudinally extending or laterally extending. A longitudinally extending SRB (for brevity, a Long-SRB) 432 is an SRB 430 with its long side 431 A extending in the longitudinal direction LI. A laterally extending SRB (for brevity, a Lat-SRB) 434 is an SRB 430 with its long side 431 A extending in the lateral direction L2. As shown in FIG. 5B, the second and third SRBs 430B-430C correspond with first and second Long-SRB s 432A-432B and the first and fourth SRBs 430A, 430D correspond with the first and second Lat-SRB s 434A-434B.

[0197] The layer 130 has three (3) large (or second) rectangular blocks (for brevity, large-blocks or LRBs), generally referenced as 450, including first through third LRBs 450A-450C, two of which are along the perimeter 180 and one is internal, each having one and a half (i.e., 1.5) times the surface area (plan view) of the SBs 410. The LRBs 450 each have first and second sides 451 A, 45 IB, with a first side that is a long side having a length that is one and a half (i.e., 1.5) times L and a second side that is a short side having a length that is L, such that the LRBs 450 have a 1.5L x L ratio in the plan view, defining a third block area that is larger than the first block area.

[0198] The LRBs 450 are arranged as either longitudinally extending or laterally extending. A longitudinally extending LRB (for brevity, a Long-LRB) 452 is an LRB 450 with its long side 451 A extending in the longitudinal direction LI. A laterally extending LRB (for brevity, a Lat-LRB) 454 is a LRB with its long side 451 A extending in the lateral direction L2. As shown in FIG. 5B, the first and second LRBs 450A, 450B correspond with first and second Long-LRB s 452A, 452B.

[0199] Along the first end 35OA of the layer 130, from the first side 360A to the second side 360B, the blocks 120 are arranged to provide the first Lat-SRB 434A, the first Long-SRB 432A, and the first and second SBs 410A, 410B. Along the second end 35OB of the layer 130, from the second side 360B to the first side 360A, the blocks 120 are arranged to provide the third SB 210C, the second Long-SRB 432B, the second Lat-SRB 434B, and the first Long-LRB 452A.

[0200] The first Lat-LRB 454 A is against the second side 36OB, between the second and third SBs 410B, 410C. The fourth SB 410D is against the first side 36OA, between the first Lat-SRB 434A and the first Long-LRB 452A. The second Long-LRB 452B is internal and is longitudinally against the second Lat-SRB 434B.

[0201] The layer 130 defines joints 475 between the blocks. As shown in the figure, with the configuration of the blocks 120 in the layer 130, the joints 475 define an X-less pattern. For example, the joints 475 define Ts.

[0202] The above mold 110 provides joints between block cavities that are X-less, i.e., the joints define Ts. As such, the layer 130 provides blocks 120 that are arranged in an X-less joint configuration.

[0203] Turning to FIGS. 5C - 5E, the figures show a method of laying two layers 130A, 130B of the type shown in FIG. 5B, longitudinally adjacent to each other, to provide an X-less joint configuration for the layers. [0204] As shown in step S100 the method includes positioning two layers 130, including first and second layers 130A, 130B on a ground so that the first layer 130A is longitudinally above and laterally offset from the second layer 130B. Specifically, a lower end 35OB of the first layer 130A is against the upper end 350A of the second layer 130B. The first and second layers are laterally offset from each other by an offset distance OD1 equal to half (0.5) of L, e.g., between the first comer 135 of the second layer 130B and a second comer 136 of the first layer 130A. The second corner 136 is defined by an intersection of the first side 360A and the lower end 35OB. With this configuration, the second comer 136 of the first layer 130A terminates at a lateral midpoint LM of the first Lat-SRB 434A of the second layer 130B. The second Lat-SRB 434B of the first layer 130 and the first SB 410A of the second layer 130B are laterally aligned and longitudinally adjacent to each other. As shown in step SI 10, the method includes swapping the second Lat-SRB 434B of the first layer 130 and the first SB 410A of the second layer 130B with each other. The resulting configuration of the first and second layers 130A, 130B provides an X-less joint pattern as shown in FIG. 5D.

[0205] FIG. 5F shows an array 480 of layers 130 of FIG. 5B built-out from the first and second layers 130A, 130B . The array 480 of layers 130 may be laid out over a driveway, roadway, patio, parking lot, park, or any area where pedestrians or automobiles may be located, stationary or moving, indoor or outdoor. The same block swapping of FIG. 5E occurs which each longitudinally adjacent ones of the layers 130 to provide an X-lcss join pattern throughout the array 480.

[0206] Turning to FIG. 6A, the figure shows another system 100 for providing a paver block configuration with X-less joints.

[0207] More specifically, FIG. 6A shows a top plan view of a mold 110 for fabricating paver blocks (or blocks) 120 in a paver block layer 130 shown in FIG. 6B. As used herein a layer is a grouping of blocks 120 that are configured to be permanently set on a ground surface without extensive reorganization. As discussed in greater detail below, according to the embodiments, when multiple layers 130 are arranged on a ground, adjacent to each other, within and between the layers 130, the blocks 120 have joints that form an X- less joint pattern.

[0208] The mold 110 is generally formed so that in the plan view it is shaped as a quadrilateral, though other shapes are within the scope of the disclosure. The mold 110 extends in a first direction, longitudinally LI, between first (or upper ) end and second (or lower) end 150A, 150B to end walls 150A1, 150B1 by a longitudinal distance LID, and in a second direction, laterally L2, between first and second sides 160A, 160B to side walls 160A1, 160A2 by a lateral distance L2D.

[0209] As shown in FIG. 6A, the perimeter (or outer boundary) 180 of the mold 110, e.g., in a plan view, is square. The distance LID between the ends 150A, 150B of the mold 110 is the same as the distance L2D between the sides 160A, 160B. The mold 110 extends heightwise from a bottom 170A to a top 170B to define a mold height MH.

[0210] With reference to FIG. 6A, the mold 110 has internal partition walls 190 that divide the mold 110 into cavities 200 that form the blocks 120. There are three (3) sizes of cavities 200, in the plan view of the mold 110.

[0211] The cavities include four (4) square block cavities (for brevity, SBCs), generally referenced as 210, including first through fourth SBCs 210A-210D, each of which are around the perimeter 180, i.e., none is internal (spaced from the perimeter). For convenience, cavities are labeled in clockwise order, from a first corner 205 defined by the intersection of the first end 150A and the first side 160A, with cavities along the perimeter 180 labeled first followed by internal cavities. The SBCs 210 each have first and second side walls (or sides) 211A, 21 IB, each having a length L, so that the SBCs 210 have an L x L ratio in the plan view and define a first cavity area. The value of the length L as referenced in each of the cavities 200 and blocks 120 is the same as each other.

[0212] The cavities 200 form four (4) small (or first) rectangular block cavities (for brevity, small-block cavities or SRBCs), generally referenced as 230, including first through fourth SRBCs 230A-230D, all of which are around the perimeter 180, each having half (0.5) of a surface area (plan view) of the SBCs 210. The SRBCs 230 each have first and second side walls (or sides) 231 A, 23 IB, with a first side that is a long side having a length L and a second side that is a short side having a length that is one-half (i.e., 0.5) L, such that the SRBCs 230 have a L x 0.5L ratio in the plan view, defining a second cavity area that is smaller than the first cavity area.

[0213] The SRBCs 230 are arranged as either longitudinally extending or laterally extending. A longitudinally extending SRBC (for brevity, a Long-SRBC) 232 is an SRBC 230 with its long side 231A extending in the longitudinal direction LI. A laterally extending SRBC (for brevity, a Lat-SRBC) 234 is an SRBC 230 with its long side 231A extending in the lateral direction L2. As shown in FIG. 6A, the second and third SRBCs 230B-230C correspond with first and second Long-SRBCs 232A-232B. The first and fourth SRBCs 230A, 230D correspond with the first and second Lat-SRBCs 234A-234B.

[0214] The cavities 200 form two (2) large (or second) rectangular block cavities (for brevity, large-block cavities or LRBCs), generally referenced as 250, including first and second LRBCs 250A-250B, one of which is along the perimeter 180 and one is internal, each having one and a half (i.e., 1.5) times the surface area (plan view) of the SBCs 210. The LRBCs 250 each have first and second side walls (or sides) 251 A, 25 IB, with a first side that is a long side having a length that is one and a half (i.e., 1.5) times L and a second side that is a short side having a length that is L, such that the LRBCs 250 have a 1.5L x L ratio in the plan view, defining a third cavity area that is larger than the first cavity area.

[0215] The LRBCs 250 are arranged as longitudinally, i.e., with their long sides 251 A extending in the longitudinal direction LI.

[0216] Along the first end 150A of the mold 110, from the first side 160A to the second side 160B, the cavities 200 are arranged to provide the first Lat-SRBC 234A, the first Long-SRBC 232A, and the first SBC 210A, and the second Long-SRBC 232B. Along the second end 150B of the mold 110, from the second side 160B to the first side 160A, the cavities 200 are arranged to provide the third SBC 210C, the second Lat-SRBC 234B, and the first LRBC 250A. [0217] The second SBC 210B is against the second side 160B, between the second Long-SRBC 232B and the third SBC 210C. The fourth SBC 210D is against the first side 160A, between the first Lat-SRBC 234A and the first Long-LRBC 252A. The second LRBC 250B is internal and is longitudinally against the second Lat-SRBC 234B.

[0218] The mold defines joints 275 between block cavities 200. As shown in the figure, with the configuration of the cavities 200 in the mold 110, the joints 275 define an X-less pattern. For example, the joints 275 define Ts.

[0219] Turning to FIG. 6B, the layer 130 is configured so that, when it is printed from the mold 110, the size, shape, orientation and placement of the blocks 120 matches that of the cavities 200.

[0220] More specifically, the layer 130 in the plan view is generally defined as a quadrilateral, though other shapes are within the scope of the disclosure. The layer 130 extends in a first direction, longitudinally LI, between first (or upper ) end and second (or lower) end 35OA, 350B, and in a second direction, laterally L2, between first and second sides 360A, 360B.

[0221] As shown in FIG. 6B, the perimeter 380 of the layer 130, e.g., in the plan view, is rectangular. The distance LID between the ends 350A, 350B of the layer 130 is the same as the distance L2D between the sides 360A, 360B. The layer 310 extends heightwise from a bottom 370A, which is positioned against a ground, to a top 370B to define a block height BH.

[0222] With reference to FIG. 6B, there are three (3) sizes of blocks 120, in the plan view in the layer 130.

[0223] The layer 130 includes four (4) square blocks (for brevity, SBs), generally referenced as 410, including first through fourth SB4s 410A-410D, each of which are around the perimeter 180, i.e., none is internal (spaced from the perimeter). For convenience, cavities are labeled in clockwise order, from the first corner 135 defined by the intersection of the first end 350A and the first side 360A, with blocks 120 along the perimeter 380 labeled first followed by internal blocks. The SBs 410 each have first and second sides 411A, 41 IB, each having a length L, so that the SBs 410 have an L x L ratio in the plan view and define a first block area.

[0224] The layer 130 has four (4) small (or first) rectangular blocks (for brevity, small-blocks or SRBs), generally referenced as 430, including first through fourth SRBs 430A-430D, each having half a surface area (plan view) of the SBs 410. The SRBs 430 each have a first and second sides 431 A, 43 IB, with a first side that is a long side having a length L and a second side that is a short side having a length that is one-half (i.e., 0.5) L, such that the SRBs 430 have a L x 0.5L ratio in the plan view, defining a second block area that is smaller than the first block area.

[0225] The SRBs 430 are arranged as either longitudinally extending or laterally extending. A longitudinally extending SRB (for brevity, a Long-SRB) 432 is an SRB 430 with its long side 431 A extending in the longitudinal direction LI. A laterally extending SRB (for brevity, a Lat-SRB) 434 is an SRB 430 with its long side 431 A extending in the lateral direction L2. As shown in FIG. 6B, the second and third SRBs 430B-430C correspond with first and second Long-SRB s 432A-432B and the first and fourth SRBs 430A, 430D correspond with the first and second Lat-SRB s 434A-434B.

[0226] The layer 130 has two (2) large (or second) rectangular blocks (for brevity, large-blocks or LRBs), generally referenced as 450, including first and second LRBs 450A- 450B , one of which are along the perimeter 180 and one is internal, each having one and a half (i.e., 1.5) times the surface area (plan view) of the SBs 410. The LRBs 450 each have first and second sides 451 A, 45 IB, with a first side that is a long side having a length that is one and a half (i.e., 1.5) times L and a second side that is a short side having a length that is L, such that the LRBs 450 have a 1.5L x L ratio in the plan view, defining a third block area that is larger than the first block area.

[0227] The LRBs 450 are arranged as longitudinally, i.e., with their long sides 451A extending in the longitudinal direction LI. [0228] Along the first end 35OA of the layer 130, from the first side 360A to the second side 360B, the blocks 120 arc arranged to provide the first Lat-SRB 434A, the first Long-SRB 432A, and the first SB 410A and the second Long-SRB 432B. Along the second end 350B of the layer 130, from the second side 36OB to the first side 360A, the blocks 120 are arranged to provide the third SB 210C, the second Lat-SRB 434B, and the first Long- LRB 452A.

[0229] The second SB 410B is against the second side 360B, between the second Long-SRB 432B and the third SB 410C. The fourth SB 410D is against the first side 36OA, between the first Lat-SRB 434A and the first Long-LRB 452A. The second LRB 450B is internal and is longitudinally against the second Lat-SRB 434B.

[0230] The layer 130 defines joints 475 between the blocks. As shown in the figure, with the configuration of the blocks 120 in the layer 130, the joints 475 define an X-less pattern. For example, the joints 475 define Ts.

[0231] The above mold 110 provides joints between block cavities that are X-less, i.e., the joints define Ts. As such, the layer 130 provides blocks 120 that are arranged in an X-less joint configuration.

[0232] Turning to FIGS. 6C - 6E, the figures show a method of laying two layers 130A, 130B of the type shown in FIG. 6B, longitudinally adjacent to each other, to provide an X-less joint configuration for the layers.

[0233] As shown in step S100 the method includes positioning two layers 130, including first and second layers 130A, 130B on a ground so that the first layer 130A is longitudinally above and laterally offset from the second layer 130B. Specifically, a lower end 35OB of the first layer 130A is against the upper end 350A of the second layer 130B. The first and second layers are laterally offset from each other by an offset distance OD1 equal to half (0.5) of L, e.g., between the first comer 135 of the second layer 130B and a second comer 136 of the first layer 130A. The second corner 136 is defined by an intersection of the first side 360A and the lower end 35OB. With this configuration, the second comer 136 of the first layer 130A terminates at a lateral midpoint LM of the first Lat-SRB 434A of the second layer 130B. The second Lat-SRB 434B of the first layer 130 and the first SB 410A of the second layer 130B are laterally aligned and longitudinally adjacent to each other. As shown in step SI 10, the method includes swapping the second Lat-SRB 434B of the first layer 130 and the first SB 410A of the second layer 130B with each other. The resulting configuration of the first and second layers 130A, 130B provides an X-less joint pattern as shown in FIG. 6D.

[0234] FIG. 6F shows an array 480 of layers 130 of FIG. 6B built-out from the first and second layers 130A, 130B . The array 480 of layers 130 may be laid out over a driveway, roadway, patio, parking lot, park, or any area where pedestrians or automobiles may be located, stationary or moving, indoor or outdoor. The same block swapping of FIG. 6E occurs which each longitudinally adjacent ones of the layers 130 to provide an X-less join pattern throughout the array 480.

[0235] Several common aspects to the above embodiments will now be identified with further reference to FIG. 1A as a non-limiting example. The mold 110 for the paver block layer 130 includes a mold outer boundary 180 that defines a square or rectangular shape. Within the mold outer boundary 180, the mold defines block shaped cavities 200. The cavities 200 include square block cavities 210, each having a first cavity area. The cavities 200 include small block cavities 230, each having a second cavity area that is smaller than first cavity area. The cavities 200 include large block cavities 250, each having a third cavity area that is larger than the first cavity area. Block joints 275 are defined by the mold 110, between adjacent ones of the block cavities 200, and the block joints 274 define an X-less configurations. The small and large block cavities 230, 250 are rectangular.

[0236] Each of the square block cavities 210 is defined by side walls 211A, 21 IB having a length L. Each of the small block cavities 230 is defined by first and second sidewalls 231 A, 23 IB having respective lengths L and 0.5L. Each of the large block cavities 250 is defined by first and second sidewalls 251A, 25 IB having respective lengths 1.5L and L. [0237] The mold outer boundary 180 is defined by first and second ends 150A, 150B that arc spaced apart from each other by a longitudinal distance LID. First and second sides 160A, 160B are spaced apart from each other by a lateral distance L2D. The mold outer boundary 180 defines one of a square, an aspect ratio of 3.5 to 3, or an aspect ratio of 4 to 3. In a rectangular configuration, the lateral distance is greater than the longitudinal distance.

[0238] Along the first side 160A of the mold 110, from the first end to the second end 150A, 150B, the mold 1110 includes a first small block cavity 230A, a first square block cavity 210D, and a first large block cavity 250B. The first small block cavity 230A is oriented so that the first sidewall 231 A extends laterally. The first large block cavity 250B is oriented so that the first sidewall 251 A extends longitudinally.

[0239] Laterally adjacent to the first small block cavity 230, along the first end 150A, is a second small block cavity 230B. Laterally adjacent to the first large block cavity 250B, along the second end 150B, is a third small block cavity 230D. Longitudinally between the second and third small block cavities 230B, 230D is a second large block cavity 250D. The second small block cavity 230B is oriented so that the first sidewall 231 A extends longitudinally. The third small block cavity 230D is oriented so that the first sidewall 231 A extends laterally. The second large block cavity 250C is oriented so that the first sidewall 251 A extends longitudinally.

[0240] Laterally adjacent to the second small block cavity 230B, along the first end 150A, is a second square block cavity 210A.

[0241] The paver blocks 120 may be made of concrete, for example a low slump mix, as a non-limiting material example.

[0242] Turning FIG. 7, and with further reference to FIGS. 1C and ID, another flowchart shows common aspects of the embodiments. Specifically, the flowchart shows a method of organizing layers 130 of paver blocks 120. As shown in step 710, the method includes obtaining first and second layers 130A, 130B formed from a mold 110 disclosed herein such that each of the paver block 120 is arranged as formed in the mold 110. As shown in step 720, the method includes laying the first and second layers 130A, 130B on a ground so that the first and second layers 130A, 130B are longitudinally adjacent and laterally offset by an offset factor OD 1 of 0.5 x L. When laid on ground, so that the first end 350A of the second layer 130B is adjacent to the second end 350B of the first layer 130A, and a lower corner 136 of the first layer 130, defined by an intersection of the first side 360A and the second end 35OB of the first layer 130A, is located along the first end 350A of the second layer 130B. As shown in step 730, the method includes swapping a small block 434B, formed in the third small block cavity 230D (FIG. 1 A) of first layer 130A with a square block 410A, formed in the second square block cavity 210A (FIG. 1A) of the second layer 130B. This action obtains an X-less joint pattern.
