The present invention relates to a method of floor construction with a grid system.

In one preferred embodiment of this invention, a method of floor construction with a grid system is provided to achieve a completed construction of a floor assembly with use of various sizes and shapes of tile members, wood members, marble members, or other materials to create a floating, non-adhesive floor installation installed without adhesive and can be readily relocated if so desired.

The method of floor construction with a grid system can be utilized to build a supporting tile floor on base support members within side walls in a given floor area such as a bathroom, kitchen, or the like.

The method of floor construction with a grid system utilizes 1) a plurality of floor grid members which can be interlocked to each other to form an overall large floor grid member assembly; 2) floor tile members of a size to interact within respective ones of the floor grid members and can be made of various types of materials such as ceramic, wood, marble, or the like; 3) cushion pad members of a size similar to the floor tile members and are to interact with the respective floor grid members; 4) grout strip members which can be provided as an elongated grout strip members or shortened grout strip members; and 5) a tile setter tool member operable to be usable between the grout strip members and with the respective floor tile members for ease of installation as will be noted.

Each floor grid member resembles a puzzle-like piece adapted to be interconnected with adjacent ones of the floor grid member to form the interlocked floor grid member assembly. Each floor grid member includes 1) a main support body; 2) grout receiving grooves extended parallel and transverse to each other; 3) male connector projections along two adjacent edges of the main support body; and 4) female lock receivers placed about the other two edges of the main support body.

The main support body has a central tile receiver section preferably of square shape but can be of rectangular or of any shape as will be noted. The main support body includes four tile half sections abutting respective outer walls of the central tile receiver sections and four tile quarter sections at outer corners thereof. Thus, each floor grid member is of a size to receive and support four floor tile members thereon.

The grout receiving grooves are preferably of 3/8" to 1/2" in width, approximately 1/16" in depth, and includes 1) first parallel groove sections; and 2) second parallel groove sections with each set of the first and second parallel groove sections extended perpendicular to each other.

Each male connector projection is f a shape and size to be interlocked with female lock receivers on other adjacent ones of the floor grid member as will be noted. More particularly, each male connector projection is provided with an anchor section integral with an outer lock section of triangular shape. The male connector projection is operable to be placed within and

interlocked with the female lock receiver as will be explained.

The female lock receiver is provided with an entrance section integral with a main lock section. The main lock section is of a triangular shape so as to receive the lock section of the male connector projection therein when in a locked condition similar to interlocking of puzzle pieces .

The floor tile members can be of any size and shape such as triangular, rectangular, and square. It would be required that the floor grid members be constructed as to receive respective ones of the particular shape of the floor tile members used therewith.

Each floor tile member has a top wall, a bottom wall, and an outer side wall and of a size and shape to be received within the central tile receiver section of the main support body of the floor grid member.

Prior to use of the method of floor construction with a grid system 8, a sufficiently rigid base support flooring 14 must be present when using the prior art methods of ceramic tile floor construction to prevent

setting of the tile members and cracking of the prior art grout. The invention herein is utilizing a special type of foam grout which is not subject to cracking.

As shown in Fig. 1, the method of floor construction with a grid system 8 includes a plurality of elements to be utilized therewith being 1) a plurality of floor grid members 16 to be interconnected to each other; 2) a plurality of floor tile members 18 which can be of various sizes and shapes as will be explained; 3) a plurality of cushion pad members 20 which can be constructed of a felt or other cushioning and sound- absorbing type material and being of a size and shape substantially identical to the floor tile members 18; 4) grout strip members 22 to be utilized with the floor grid member 16 to achieve a grout appearance about an outer periphery of respective floor tile members; and 5) a unique tile setter tool member 24 to aid in the method of floor construction with a grid system 8 as will be explained.

The floor grid member 16, as noted in Fig. 2, is to be interconnected to additional floor grid members 16 to form a floor grid member assembly 26 as noted in Fig. 7. Each floor grid member 16 includes 1) a main support body 28; 2) grout receiving grooves 30; 3) male connector projections 32; and 4) female lock receivers 34.

The main support body 28 is provided with 1) a central tile receiver section 35; 2) four tile half sections 37; and 3) four tile quarter sections 39. Each floor grid member 16 has a total of four complete square

sections to receive the floor tile members 18 therein when assembled as noted in Fig. 9.

The grout receiving grooves 30 are formed with first parallel groove sections 36 and second parallel groove sections 38 which are directed perpendicular to the first parallel groove sections 36.

Each floor grid member 16 has four of the male connector projections 32 and four of the female lock receivers 34. Each male connector projection 32 includes an anchor section 40 integral with a lock section 42 being of generally triangular shape.

Each female lock receivers 34 has an entrance section 44 integral with a main lock section 46. The main lock section 46 is adapted to receive the lock section 42 therein in a puzzle-like engagement as shown in Fig. 7.

The main lock section 46 has side walls 48 leading into an end wall 50. The side walls 48 and end wall 50 are adapted to receive and lock the lock section 42 of a respective male connector projection 32 therein to prevent lateral, horizontal movement.

The floor tile members 18 can be of any shape such as triangular, square, or rectangular but normally square sizes would be utilized. The floor tile members 18 can be constructed of a ceramic material, marble plate, wooden parquet, and any other type of material that is preferably waterproof. Each floor tile member 18 has a top wall 52, a bottom wall 54, and outer peripheral side walls 56.

The cushion pad member 20 is of a size substantially identical or slightly smaller than the floor tile members 18. The cushion pad member 20 is preferably constructed of a felt material or the like to provide a cushion and sound-proofing to the floor tile members 18 when being walked upon in the assembled condition as will be explained. Each cushion pad member 20 is provided with a top wall section 58, a bottom wall section 60, and outer peripheral side wall sections 62.

As noted in Fig. 5, the grout strip members 22 include elongated grout strip members 64 which may be cut to shorter grout strip members 66 (see Fig. 1) . Each grout strip member 22 has a top outer surface 68, a bottom outer surface 70, and spaced parallel side wall surfaces 72.

The bottom outer surface 70 is provided with an outer adhesive layer 74 protected by a cover sheet 76 which is removed to expose the adhesive layer 74 in a process step as will be explained.

The grout strip members 22 resemble insulation strips utilized about doors and windows to seal cracks and the like during a weather sealing operation. The top outer surface 68 can be of various colors such as gray, white, and black but can be manufactured in any color as so desired. In other words, a light blue color for the top outer surface 68 of the grout strip members 22 might be used when utilizing a blue floor tile member 18.

As noted in Fig. 6, the specially designed tile setter tool member 24 includes a main tool body 78 having 1) upper edges 80; 2) four handle members 82 on the upper

edges 80; 3) a rigid upper section 84; 4) a flexible bottom section 86 integral with the rigid upper section 84; 5) corner slit sections 88 in the bottom section 86 to cause its flexibility; and 6) lower edges 89 to be placed on or about the cushion pad member 20 during a floor construction method step as will be explained.

The tile setter tool member 24 is operable so that the lower edges 89, due to the corner slit sections 88 at each corner thereof, are allowed to expand outwardly when receiving a respective floor tile member 18 thereagainst in a manner to be noted. The tile setter tool member 24 can be constructed of a lightweight material being of aluminum or a plastic material.

In a second embodiment of this invention as shown in Fig. 10, a method of floor construction with a grid system 8 is utilized in the same previously described floor area 10 to produce a floor grid member assembly 26 therein.

The new method of floor construction with a grid system 8 includes 1) a floor grid member 16; 2) a plurality of the floor tile memb^ "s 18; 3) selective use of the cushion pad members 20; *-. a newly designed grout strip member or assembly 96 to be used with the floor grid members 16; and 5) use of the tile setter tool member 24 if so desired.

As best shown in Fig. 11, each floor grid member 16 includes 1) a main support body 28 having a pair of parallel, spaced, adjacent grout receiving areas or projections 94 facing each other; 2) male connector projections 32; and 3) female lock receivers 34.

The male connector projections 32 are selectively connected to the female lock receivers 34 in a dovetail manner as previously described in the first embodiment .

The main support body 28 is provided with a central tile receiver section 35 surrounded by tile half sections 37 and tile quarter sections 39. The central half and quarter tile receiver sections 35, 37, 39 are divided into these respective areas by the spaced parallel grout receiving projections 94 as noted in Figs. 10 and 11.

Each grout receiving projection 94 includes 1) a bottom wall 102; 2) an outer wall 104; 3) a top wall 106; and 4) an inner wall 108 having a pair of spaced parallel V-shaped retainer projections 110 extended an axial length of the grout receiving projections 94. Each retainer projection 110 is operable to engage a similar shaped one-way retainer or blade member on the grout strip assemblies 96. as will be explained.

The cushion pad members 20 are an optional feature of the second embodiment in the method of floor construction with a grid system 8 whereupon it may or may not be utilized therewith to achieve a desired cushioning effect .

Each grout strip assembly 96 is of a Greek cross shape having a central portion 97 with lateral projections therefrom of equal length. Each grout strip assembly 96 includes 1) a plurality of grout strip legs or projections 112 extending from the central portion 97; 2) anchor connector members 114; 3) outer ends of a pair of the grout strip legs 112 are provided with male connector ends 116; and 4) another pair of the outer ends

of a second pair of the grout strip legs 112 are formed with female connector ends 118.

Each grout strip leg 112 is provided with an arcuate top grout surface 119 which is of a desired selected color and being a top smooth or textured surface resembling of a bead of grout material when in the assembled condition with a floor tile member 18.

Each anchor connector member 114 is provided with a support section 120 integral at an outer end thereof with an anchor V-section 122 which extends the length of each grout strip leg 112. Each anchor connector member 114 is operable to be engaged with respective grout retaining members 98 in the grout receiving projections 94 of respective floor grid members 16 as will be explained.

Each anchor V-section 122 is provided with a blade portion 124 centrally integral with each other and an outer end of the support section 120. Each blade portion 124 includes an outer pointed anchor end 126 engageable with the retainer projections 110 on the grout retaining members 98 to achieve a one-way anchor.

Each male connector end 116 is provided v/i th an anchor tenon projection 128 extended from an outer end of two of the grout strip legs 112 on each of the grout strip assemblies 96.

Each female connector end 118 on other outer ends of two of the grout strip legs 112 of the grout strip assembly 96 is provided with an anchor mortise recession 130 operable to receive and be interlocked with an adjacent anchor tenon projection 128 when assembled.

The male connector end 116 and the female connector end 118 are operable to be interlocked in a known dovetail manner as the anchor tenon projection 128 is a projecting member for insertion into the anchor mortise recession 130 to provide the dovetail connection therebetween to prevent axial and lateral movement when interconnected relative to each other (Fig. 1) .

The main purpose of the tile setter tool member 24 is that it can be placed within an inner periphery of, for example, a central tile receiver section 35 of a floor grid member 16 during the assembly process. More specifically, the lower edges 89 of the flexible bottom section 86 are to be placed between the grout strip members 22. An inserted floor tile member 18 is operable to provide compression of the adjacent grout strip members 22 in the assembly procedure. This compression of the adjacent grout strip members 22 is very difficult to do without use of the tile setter tool member 24. USE AND OPERATION OF THE INVENTION

In the use and operation of the method of floor construction with a grid system 8 of this invention, it is obvious that we first define a floor area 10 within the side walls 12 and having the base support flooring or base support member 14 already mounted thereon or placed thereon during a new construction. The base support members 14 may be of a 3/4" or 1" thick plywood construction placed on a plurality of parallel spaced floor joists (not shown) .

In the method of floor construction with a grid system 8 of this invention, the following method steps are noted:

1) installing a sufficient sub-floor in the floor area 10 to receive a floor construction thereon;

2) laying out a plurality of the floor grid members 16 in a sufficient number to cover the floor area 10;

3) interlocking the plurality of floor grid members 16 to form the floor grid member assembly 26 to cover the floor area 10;

4) moving the interlocked floor grid members 16 formed into the floor grid member assembly 26 around the floor area 10 to minimize the required number of floor grid members 16 to be cut to cover the entire floor area 10;

5) cutting floor grid members 16 in order to fit against abutting wall areas, appliances, and the like in order to completely cover the floor area 10;

6) installing the elongated grout strip members 64 into spaced parallel first parallel groove sections 36 after removing the cover sheet 76 to expose the adhesive layer 74;

7) cutting grout strip members 22 or elongated grout strip members 64 into the shortened grout strip members 66 to cover space between the parallel elongated grout strip members 64 installed in step 6) above;

8) installing the shorter grout strip members 66 into the second parallel groove sections 38 between the elongated grout strip members 64;

9) installing respective cushion pad members 20 within the normally square areas between the installed grout strip members 22;

10) placing the tile setter tool member 24 within the square areas defined by the grout strip members 22 and placed against or about a cushion pad member 20 installed in step 9) above;

11) inserting a floor tile member 18 into the open, upper end of the tile setter tool member 24 and moving subject floor tile member 18 downwardly in a plane parallel to the floor area 10 and the cushion pad member 20;

12) holding the floor tile member 18 with a user's one hand against the cushion pad member 20;

13) expanding the flexible bottom section 86 and lower edges 89 of the tile setter tool member 24 which compresses adjacent portions of the grout strip members 22;

14) removing the tile setter tool member 24 with the use of the user's other hand from about the floor tile member 18 which allows the surrounding peripheral grout strip members 22 to expand and hold the floor tile member 18 snugly in place;

15) repeating the above steps 10) -14) , inclusive, for each floor tile member 18 to be installed;

16) cutting the floor tile members 18 and a cushion pad member 20 to be associated respectively therewith to size in order to fit about the outer peripheral edges of the floor grid member assembly 26 and completely cover the floor area 10;

17) taking the cut floor tile members 18 and cushion pad members 20 from above step 16) and mounting about the outer peripheral edges of the floor grid member assembly 26 to completely cover the floor area 10; and

18) cleaning up the area, removing cut and unusable floor tile members 18 and cushion pad members 20, remove the tools, and generally finish the method of floor construction 8.

The method steps 10) -14) , inclusive, using the tile setter tool member 24 can be replaced with the user inserting each floor tile member 18 into the square areas between the grout strip members 22. The floor tile member 18 is then shifted about until the bottom wall 54 rests on the top wall section 58 of the adjacent cushion pad member 20. This causes the adjacent portions of the grout strip members 22 to be compressed and the floor tile member 18 is held snugly in place. This method step is repeated until all of the floor tile members 18 are installed within the floor grid member assembly 26.

The floor grid member 16 is preferably of a plastic material and preferably of a 1/8" thickness and having the grout receiving grooves 30 approximately 1/16" in depth. The central tile receiver section 35 is preferably a 4" x 4" or 1' x 1' size. The grout receiving grooves 30 can be 3/8" or 1/2" in width to receive the grout strip members 22 of identical width on each floor grid member 16 therein.

The male connector projections 32 and the female lock receivers 34 can be of various irregular shapes. The use of four each of the male connector projections 32

and the female lock receivers 34 will provide a rigid interconnection of adjacent floor grid members 16 to form the floor grid member assembly 26 as noted in Fig. 7.

The floor grid members 16 can be adapted to be used with various shapes of tile such as triangular, square, circular, or rectangular.

The floor tile members 18 can be of various sizes, shapes, and thickness as the floor grid members 16 can be designed to be utilized with the various sizes, shapes, and types of floor tile members 18.

The tile setter tool member 24 can be changed in sizes and designs to accommodate rectangular or square floor tile members 18 to assist in the installation thereof within the floor grid member assembly 26.

In the method steps of construction utilizing the second embodiment of this invention as shown in Figs. 10-13, the initial method steps as previously described are as follows:

1) installing a sufficient sub-floor in the floor area 10 to receive a floor construction thereon;

2) laying out a plurality of the floor grid members 16 in a sufficient number to cover the floor area 10;

3) interlocking the plurality of floor grid members 16 to form the floor grid member assembly 26 to cover the floor area 10;

4) moving the interlocked floor grid members 16 formed into the floor grid member assembly 26 around the floor area 10 to minimize the required number of floor

grid members 16 to be cut to cover the entire floor area

10; and

5) cutting floor grid members 16 in order to fit against abutting wall areas, appliances, and the like in order to completely cover the floor area 10.

On having the floor grid members 16 of the second embodiment (Figs. 11 and 12) interconnected through the male connector projections 32 and the female lock receivers 34, the next method step is to insert the cushion pad members 20, if so desired, between the various tile receiving areas of the grout receiving projections 94. At this time, the tile setter tool member 24 may be utilized as deemed necessary but may not be needed to be utilized due to the vertical spacing of the grout receiving projections 94 to define the receiving areas to support the respective cushion pad members 20 and the floor tile members 18 therebetween.

The next method step for the operator would be to insert the grout strip assemblies 96 between abutting four corners of the floor tile members 18 as noted in Fig. 10. The respective grout strip assemblies 96 are to be pressed downwardly in a snapped-in fashion whereupon the retainer projections 110 on the grout receiving projections 94 are operable to be engaged with the blade portions 124 on the anchor V-sections 122 of the anchor connector members 114 in a one-way locking relationship.

Depending on thickness of the floor tile members 18 and whether a cushion pad member 20 is utilized, the upper retainer projections 110 on the grout receiving projections 94 will engage the pointed anchor end 126 of

the blade portions 124 of the anchor V-sections 122.

This achieves a compression force from the top wall 106 of the grout receiving projections 94 to provide a downward bias force to hold the respective floor tile members 18 against the respective main support bodies 28.

On attaching further ones of the grout strip assemblies 96, various ends of the male connector ends 116 or the female connector ends 118 are operable to engage and connect to each other as noted with use of the two grout strip assemblies 96 in Fig. 10.

The connection between the retainer projections 110 on the grout receiving projections 94 and the pointed anchor ends 126 on the anchor V-sections 122 of the grout strip assemblies 96 has been described as a "one-way anchor or locking relationship" . However, due to flexibility of the retainer projections 110 and the anchor V-sections 122, the respective grout strip assemblies 96 can be removed for repair, replacement, or removal of the floor tile members 18 and the cushion pad members 20 as desired for further usage.

It is noted that the method of floor construction with a grid system 8 can be used with the floor grid members 16 and grout strip members or assemblies 96 against a wall area to attach floor tile members 18 thereagainst such as in a bathroom tub and shower area or to achieve a decorative wall.

The procedure of adding the floor tile members 18 with or without the cushion pad members 20 into the areas of a size of a central tile receiver section 35 is then continued until an entire floor grid member assembly 26

is achieved similar to that described for the first embodiment of the method of floor construction with a grid system 8 of this invention.

The method of floor construction with a grid system 8 of this invention allows for construction of a floating, non-adhesive floor installation whereupon nothing needs to be securely fastened to the sub- flooring. However, it may be desirable to utilize a few nails to anchor the floor grid member assembly 26 to the base support members 14 prior to proceeding with installation of the cushion pad members 20 and the floor tile members 18.

Further, the method of floor construction with a grid system of this invention can be 1) normally installed in an efficient manner, not requiring skilled labor to do so; 2) used with economical floor grid members having the grout strip members therein which does not require the skilled labor of a floor installer and mixing and use of prior art grout material; 3) used to achieve an installed floor system which can be readily removed and reusable in a different floor area; and 4) used to achieve an installed floor system with a specially designed tile setter tool member to simplify the floor construction process, not requiring one skilled in this area.

The method of floor construction with a grid system of this invention allows the average homeowner, whether owning a home, renting an apartment, or renting a house, to install a completed floor installation without concern for loosening tiles being improperly installed.
