Figures 1 A-L depict an adjustable modular frame system 100 according to some embodiments. These figures show the different components of system 100. Figures 1A, 1C, and ID depicts views of system 100 assembled without being adjusted beyond its smallest configuration. Figure IB depicts an exploded view of a disassembled system 100. Figures IE, IF, 1G, and 1H depict exploded views of the various components disclosed below.

Figures II, 1J, IK, and 1L depict perspective views of these components.

System 100 is adjustable in the lengthwise and widthwise directions. System 100 includes at least six distinct pieces that comprise the four sided member with one edge connected to a pair of adjacent but parallel edges. Each edge has an opposite edge with one set of parallel edges having an extended lip on the interior to allow support for a flat surface, such as a mattress, box spring, or cushion. Flat objects may rest on system 100 without the probability of slippage. A center bar extends in the same direction of the pair of edges with the lip and at the same planar level of the aforementioned edges. Preferably, system 100 is about 448.56 mm high, 1561 mm long, and 1119.53 mm wide, before it is expanded or adjusted. System 100 may be adjusted to fit any size, length, and width.

System 100 includes a pair of first corner supports 110, a pair of second corner supports 120, a pair of T-section supports 130, a center bar 140, and U-channel inserts 160 for support pieces 150. These components may be adjusted as needed to vary the dimensions of system 100. Each component is disclosed in greater detail below.

First corner supports 110 are located in opposite corners of system 100. Second corner supports 120 are located in the other corners. Thus, each side of system 100 includes one first corner support 110 and one second corner support 120. First corner support 110 includes a pair of rectangular tubes 111 and 112 extending perpendicularly so as to form a 90 degree angle. As shown, first rectangular tube 111 is slightly longer than second rectangular tube 112. The rectangular tubes also may be known as "arms." The rectangular tubes are connected to leg 113, which may be a tubular square that rests on the floor, ground, or surface.

First rectangular tube 111 connects to rectangular U-channel insert 160 having a rectangular end cup. First rectangular tube 111 also includes lip 1110, which extends inwardly to a center area enclosed by system 100. Rectangular U-channel insert 160 is enclosed by support piece 150, which includes lip 152. Lips 1110 and 152 are used to support the flat surface of the cushion, mattress, and the like for furniture. Second rectangular tube 112 extends perpendicularly from first rectangular tube 111. Second rectangular tube 112 attaches to T-section support 130. Second rectangular tube 112 includes a set of holes to receive screws 1101 that secure adapter parts 1102, 1103, and 1104 that receives the tracks of T-section support 130. Second rectangular tube 112 also includes holes 1106 that allow for other objects to slide into system 100 for a firm support. Preferably, the number of holes from screws 1101 is sixteen while the number of holes 1106 is 2.

As shown with first corner support 110, U-channel insert 160 includes track 162 that attaches to outer portion 166 with screws 164. Tracks 162 allows U-channel insert 160 to mate with second corner support 120, as disclosed below. First rectangular tube 111, however, receives U-channel insert 160 without engaging track 162.

Components of first corner support 1 10 may have the following dimensions.

Preferably, first rectangular tube 111 is about 140 mm by 60 mm by 3 mm. The square lip on first rectangular tube 111 may be about 30 mm by 30 mm by 30 mm.

Second corner support 120 also includes a first rectangular tube 121 and a second rectangular tube 122. First rectangular tube 121 and second rectangular tube 122 are connected at a perpendicular angle at leg 113. Tubes 121 and 122 differ from tubes 111 and 112 of first corner support 110. For example, second rectangular tube 122 may be longer than first rectangular tube 111, while second rectangular tube 112 is about at the same size as first rectangular tube 121. Second rectangular tube 122 includes square lip 1210 extending inwardly to a center area enclosed by system 100. First rectangular tube 121 includes a rectangular end cup attached on the outer most edge away from leg 113. Both tubes 121 and 122 include sets of sixteen holes to receive screws 1101 and 1201, respectively. First rectangular tube 121 uses the holes and screws 1101 to secure adapter parts 1102, 1 103, and 1104 that receives the tracks of T-section support 130. Thus, first rectangular tube 121 may face or touch second rectangular tube 112 of first corner support 1 10. Second rectangular tube 122 uses the holes and screws 1201 to secure adapter parts 1202, 1203, and 1204. Adapter parts 1202, 1203, and 1204 differ from adapter parts 1102, 1103, and 1104 as they are longer. Adapter parts 1202, 1203, and 1204 receive tracks 162 of U-channel insert 160. First rectangular tube 121 also includes holes 1106 located above leg 113.

Corner supports 110 and 120 may be connected directly together using the track assemblies of U-channel insert 160 and T-section support 130. The respective rectangular tube may engage the tracks. T-section supports 130 may be placed between second rectangular tube 112 and first rectangular tube 121. These are the tubes without lips. T- section supports 130 also connect with center bar 140 to provide support within system 100.

T-section support 130 includes upper part 131 and lower part 132. Upper part 131 may engage rectangular tubes 112 and 121, while lower part 132 engages center bar 140. Lower part 132 is located below upper part 131 and extends perpendicularly inwards to frame 100. Preferably, upper part 131 is longer then lower part 132. Upper part 131 houses the track section of T-section support 130. Thus, track 162 is secured by screws 164 to outer portion 1301. Preferably, twenty eight holes and screws are placed intermittently in pairs across the length of track 162. Track 162 couples or engages with the adaptors used in first corner support 110 and second corner support 120. Lower part 132 includes support bar 1302, or T-section, that attaches to channel track 1304 using screws 1302, 1303, and 1305. Center bar 140 is placed between two T-section supports 130 and engages lower parts 132. In other words, lower parts 132 hold center bar 140. Center bar 140 may be a horizontal tube that placed perpendicularly to T-section support 130. It acts as a base for system 100. Center bar 140 includes leg 1401 held in place by a pair of triangular gussets. Center bar 140 also includes two sets of adapters 1402 and 1403 placed at the open ends. Adapter 1402 includes a channel to engage channel track 1304. Thus, center bar 140 is secured between T-section supports 130.

System 100 also includes support piece 150, as disclosed above. Support piece 150 may enclose U-channel insert 160, which includes track 162. Support piece 150 may engage first rectangular tube 111 of first corner support 110 and second rectangular tube 122 of second corner support 120. Support piece 150 includes lip 152. Lip 152 may be slightly larger than lips 1110 and 1210. Support piece 150 may act as a bridge protector between first corner support 110 and second corner support 120. System 100 may extend or contract without any damage to the underlying components. For example, various sizes of U-channel insert 160 may be used to adjust the size of system 100. Support piece 150 also may vary in size to accommodate the size of a U-channel insert 160. As shown in Figure 1, support piece 150 may cover the rectangular tubes on the outside.

Head accessory 170 acts as a protective encasement, or back cover, for rectangular tubes 112 and 121. As such, head accessory 170 may cover upper part 131 of T-section support 130.

Using the disclosed configuration, system 100 may be adjusted in size and shape. First corner supports 110 may provide a fixed part to hold U-channel inserts 160. As indicated above, the systems may act as a frame that expands length-wise and width-wise. The process by which the frame can be expanded is a manual process. The individual attempting the expansion may pull length-wise and width-wise. The system expansion has indicators informing the user of the appropriate length markers for the possible mattress size i.e. twin, full, queen and king configurations. These markers provide the appropriate dimensions for the user.

Alternatively, slots 304 and 306 may be on sides 302 opposite each other such that each side includes slots. Slots 304 and 306 are sets of four slots, though any number of slots may be used. The slots received protrusions from the rails, disclosed in greater detail below. Slots 304 and 306 may have dimensions of a width of about .085 cm and a length of about .625 cm. Slots 304 and 306 may include two top slots with tops of about .25 cm from an end of side 302. Two bottom slots may be about 1.5 cm from the end of side 302, as shown in Figure 3B. The slots also may be two slots on each side that are spaced apart from each other by about 1.112 cm and located about .444 cm from the edges of side 302. Referring to Figure 2C, leg 201 may include a hollow center 308 to configure the leg as square tubing. Leg 201 also includes edges 310, which are rounded. This prevents the use of sharp edges when assembling system 200.

Figures 4A-J depicts a support rail 202 for system 200 according to the disclosed embodiments. Although top support rail 202 is shown, Figures 4A-H also may apply to bottom support rail 204. Support rail 202 may attach to two legs 201 using flatbars 411 and mounting projections 420. Mounting projections 420 fit into slots 304 and 306 of legs 201.

Figure 4A depicts an exploded view of support rail 202. Support rail includes a middle support piece 402 and a pair of adjustable support pieces 404 and 406. Adjustable support piece 404 may be the left side adjustable support piece. Adjustable support piece 406 may be the right side adjustable support piece. Middle support piece 402 shown in Figure 4D also includes a slot 408 located approximately in the middle of the middle support piece. Slot 408 receives a tab from center rail 210. Slot 408 may be flat with a length of about 1.42 cm.

As can be seen in Figure 4A, adjustable support pieces 404 and 406 fit inside middle support piece 402 such that they are movable to adjust the length of support rail 202. Screws 410 may insert through a hole 4025 on each side of middle support piece 402 and into a corresponding hole 4048 on adjustable support pieces 404 and 406. The holes in the adjustable support pieces may correspond to a desired size for system 200. Referring to Figure 4H, markings 4046 indicate the size for corresponding holes 4048. Using a bed example, the markings may indicate the hole to insert screw 410 to achieve the desired size for the bed. Thus, markings 4046 may indicate twin, full, queen, California king, and king sizes. One moves adjustable support piece 404 or 406 within middle support piece 402 to align with the proper marking and inserts screw 410 into the holes. A nut may engage screw 410 to provide further stability for system 200.

Figure 4E depicts a side view of middle support piece 402. Middle support piece 402 is hollow with a bottom side 4020. Bottom side 4020 includes a channel 4024. Channel 4024 is bounded by a flat support portion 4022 and a bent portion 4026. Flat support portion 4022 may extend about halfway across bottom side 4020. Bent portion 4026 extends inwardly into the hollow midsection of middle support piece 402. Bent portion 4026 provides a groove to engage a side 4045 of each adjustable support piece. Side 4045 slides into bent portion 4026 to adjust system 200. Bent portion 4026 also supports adjustable support pieces 404 and 406. Flat support portion 4022 also provides support for adjustable support pieces while inside middle support piece 402. Flat section 4042 of each adjustable support piece 404 and 406 may rest on flat support portion 4022. Flat section 4042 is shown in Figure 4G.

Adjustable support piece 404 or 406 also includes a channel 4044 so that channels 4024 and 4044 overlap each other. Adjustable support pieces 404 and 406 also include flatbars 411. Flatbar 411 is shown in Figure 4J. Flatbar 411 includes holes 412. Hole 412 may have an oval shape and engage with leg 201. In other words, a hole 412 may overlap hollow center 308. Holes 412 also may allow pieces of furniture to be mounted on system 200. For example, a headboard may be fit into corresponding hole 412 for a bed. Flatbar 411 may be about 4 cm to 5 cm in length, and, more particularly, may be about 4.273 cm in length. Flatbar 411 may have a width of about 1.5 cm to 2 cm, and, more particularly, may be about 1.75 cm. Centers of holes 412 in each flatbar 411 may be about 2.5 cm to 3 cm apart. More particularly, the centers may be about 2.746 cm apart. As shown in Figures 4G and 41, flatbar 411 may fit into an extension portion 4041 of each adjustable support piece. Adjustable support pieces 404 and 406 include holes 4043 to align with holes 412. Preferred dimensions for middle support piece 402 and adjustable support pieces 404 and 406 may be provided. Middle support piece 402 may be about 35 cm to 40 cm in length, and, more particularly, about 38.74 cm in length. The distance between holes 4025 may be about 38 cm. The distance from an end of middle support piece 402 and a middle of slot 408 may be about 19.38 cm. The width of middle support piece 402 may be about 2 cm to 3 cm. More particularly, the width may be about 2.2 cm. The depth of middle support piece 402 may be about 3 cm to 3.5 cm. More particularly, the depth may be about 3.188 cm. A length of flat support portion 4022 may be about 1 cm. A length of bent portion 4026 may be about .50 cm. Adjustable support pieces 404 and 406 may have a top side length of about 22 cm to

23 cm, and, more particularly, a top side length of 22.89 from an end 4047 of the adjustable support piece inserted into middle support piece and the end of extension portion 4041. The width of each adjustable support piece may be about 2 cm to fit within the width of middle support piece 402. The depth of each adjustable support piece may be about 3 cm to also fit within the depth of middle support piece 402. As shown in Figure 41, end 4047 narrows slightly from the width of adjustable support piece 404 or 406.

Mounting projections 420 project from end 4049 of each adjustable support piece. Mounting projections 420 fit into slots 304 and 306 of legs 201 to mount support rail 202 or 204. Preferably, there are four mounting projections 420 for each adjustable support piece 404 or 406. Mounting projections 420 may include a downwardly shaped portion that goes into the slots on legs 201 to mount to the legs. Mounting projections 420 should not dislodge from legs 201 absent some movement of the support rails to do so. Figures 4B and 4C depict support rail 202 in an extended configuration with adjustable support pieces 404 and 406 moved to the "full" bed configuration as shown by markings 4046. Adjustable support pieces 404 and 406 fit and move within middle support piece 402.

Figures 5A-G depict side rail 206 according to the disclosed embodiments. Side rail 208 also may include the configuration and concepts disclosed in Figures 5A-G. Side rails 206 and 208 attach to legs 201 using mounting projections 510. Mounting projections 510 insert into slots 304 and 306. Side rails 206 and 208 differ from support rails 202 and 204 in that they also include lips 508 and 509. Lips 508 and 509 provide support for a piece of furniture to rest upon. Side rails 206 and 208 also are adjustable to configure into a variety of sizes for system 200.

Referring to Figure 5A, the components of side rail 206 are shown. Side rail 206 includes middle side piece 502 having a lip 508 extending inwardly towards a center area enclosed by system 200. Side rail 206 also includes a pair of adjustable side pieces 504 and 506 that fit and move inside middle side piece 502. Adjustable side piece 504 may be referred to as the left adjustable side piece and adjustable side piece 506 may be referred to as the right adjustable side piece. Each adjustable side piece also includes a lip 509.

Side rail 206 includes holes 517 that receive screws 515 to adjust the length of the side rail using adjustable side pieces 504 and 506. Referring to Figure 5F, markings 520 and holes 522 are shown. One moves adjustable side pieces 504 and 506 to a desired size, such as twin/full, queen/king, or California king, using markings 520. The appropriate hole 522 corresponding to the marking is aligned with hole 517 of middle side piece 502. Screw 515 is placed through holes 517 and 522 to secure the adjustable side piece to the middle side piece. This process is repeated for the other adjustable side piece.

Figure 5B depicts a side view of side rail 206. Mounting projections 510 are included on the ends of adjustable side pieces 504 and 506 opposite middle side piece 502. Like mounting projections 420, mounting projections 510 engage slots 304 and 306 of legs 201 to keep system 200 off of the floor. Preferably, there are four mounting projections 510 for each adjustable side piece 504 and 506. Mounting projections 510 may include a downwardly shaped portion that goes into the slots on legs 201 to mount to the legs.

Mounting projections 510 should not dislodge from legs 201 absent some movement of the support rails to do so. Further, markings 520 and holes 517 for adjusting side piece 206 are shown. Figure 5C depicts a top view of side rail 206. This figure shows lips 508 and 509 used to support furniture or other items using system 200. Lips 509 may be slightly smaller than lip 508. As adjustable side pieces 504 and 506 move within middle side piece 502, lips 509 are positioned below lip 508. Thus, lip 508 may rest on lips 509. This configuration may prevent buckling of side piece 206 once weight is placed on lips 508 and 509. Figures 5D-G depict more detailed views of adjustable side piece 504 or 506.

Adjustable side piece 504 is referred to in the following description for simplicity. Figure 5D depicts a perspective view of adjustable side piece 504. Figure 5E depicts a top view, Figure 5F depicts a side view, and Figure 5G depicts a bottom view. End 524 of adjustable side piece 504 may be tapered slightly to better fit into middle side piece 502. The bottom side includes channel 5042 and flat section 5044. Flat section 5044 may rest on flat support portion 5022 of middle side piece 502. Thus, middle side piece 502 also includes a channel 5024 on its bottom to allow lip 509 to connect to adjustable side piece 504.

Preferred dimensions for adjustable side piece 504 include a length of about 28 cm to 29 cm. More particularly, the length is about 28.5 cm. A length to the beginning of the tapered portion of end 524 is about 28 cm. Adjustable side piece 504 also may have a width of about 1.5 cm to 2.5 cm, or, more particularly, a width of about 2.0 cm. It also may have a depth of about 2.5 cm to 3.5 cm. More particularly, the depth may be about 3.0 cm to flat section 5044 and 3.03 cm to lip 509. Thus, the side of adjustable side piece 504 having lip 509 is longer than the opposite side. This configuration allows adjustable side piece 504 to fit and move within middle side piece 502. The length of lip 509 may be about 1.5 cm and the length of flat section 5044 may be about .875 cm.

Figures 6A-E depict center rail 210 of system 200 according to the disclosed embodiments. Referring back to Figure 2B, center rail 210 fits between top support rail 202 and bottom support rail 204. Center rail 210 also is adjustable to fit the desired configuration of system 200. Center rail 210 includes middle center piece 602 and a pair of connecting pieces 604 and 606 that slidably fit into the middle center piece. Connecting pieces 604 and 606 may move within middle center piece 602 to adjust the length of center rail 210. These components of center rail 210 may vary in thickness to make this component more rigid. In other words, if center rail 210 is made thicker, then it also is more rigid to provide more support.

Middle center piece 602 also connects to leg piece 211. Leg piece 211 provides support to center rail 210 as it does not connect to legs 201. Leg piece 211 prevents center rail from buckling or bending towards the floor, and also provides the necessary clearance underneath any furniture item supported by system 200. Screw 608 inserts through hole 610 to engage washer 612. Washer 612 fits into a top of leg piece 21 1. Washer 612 also may be referred to as a fitting having a hole to receive screw 608. Figure 6E shows an example of leg piece 211. Leg piece 211 may be round with a hollow center.

Connecting pieces 604 and 606 then may be placed into middle center piece 602. Connecting pieces 604 and 606 are configured to fit into the midsection of middle center piece 602. As shown, pieces 602, 604, and 606 are thin, substantially flat pieces so that the furniture item can rest on center rail 210 without snagging any material. They also have a rounded top section to not tear or snag material as well as allow for some movement of the furniture item when placed on system 200.

Connecting pieces 604 and 606 each include a tab 616. Tab 616 may be shown in Figures 6C and 6D. Tabs 616 are located on ends 618 of connecting pieces 604 and 606. Tabs 616 are placed into slots 408 of support rails 202 and 204. Tabs 616 extend

substantially downward to hook into slots 408. Thus, center rail 210 is located substantially in the middle of system 200. Center rail 210 may have a height of about 6.5 cm to 7.2 cm from the top of middle center piece 602 and the bottom of leg piece 211. More particularly, the height may be 6.95 cm.

In some embodiments, more than one center rail 210 may be implemented in system 200. In such a case, middle support piece 402 may include multiple slots 408 to receive tabs 616 from the center rails. Multiple center rails may be desired for a large system 200, or when the furniture item is heavy such that the system needs extra support. Center rail 210 preferably is configured "length-wise" within system 200 but may be configured "width- wise" in that tabs 616 engage slots within middle side piece 502. Alternatively, more than one leg piece 211 may be connected to middle center piece 602 to provide extra support.

Although system 200, as well as system 100, discloses the use of markings and holes that correspond to sizes of beds, the embodiments are not so limited. Any number of holes may be used to adjust the size of system 200. For example, a plurality of holes may be used on adjustable support pieces 404 and 406 as well as adjustable side pieces 504 and 506. These holes may be spaced apart at uniform distances and not according to predetermined sizes. Thus, system 200 may accommodate many different types of furniture configurations beyond beds, such as couches, chairs, and the like. Alternatively, adjustable pieces 404, 406, 504, and 506 may have notches that fit into notches in middle pieces 402 and 502. Each notch may include a hole corresponding to its location so that one may count how many notches for each adjustable piece. Then the screws are fit through the holes to construct system 200.

It will be apparent to those skilled in the art that various modifications to the disclosed golf teaching aid system without departing from the spirit or scope of the invention. Thus, it is intended that the present invention covers the modifications and variations disclosed above provided that these changes come within the scope of the claims and their equivalents.
