DETAILED DESCRIPTION

[0019] FIGS. 1 and 2 show an embodiment of a floor tile 100 which has a top surface 110 (FIG. 1), an optional bottom surface 120 (FIG. 2), and marginal faces 130 which may extend at least partially along a perimeter of the top surface 110. Top surface 110 may be generally even and regular. In some embodiments, voids 111 may defined in the top surface 110, e.g., to allow for drainage, as shown in FIG. 4.

[0020] Bottom surface 120 includes a support structure 122, which supports the tile 100 above the surface. The support structure 122 may include portions 123b that extend from the bottom surface 120 provide strength to the tile top surface 110. Additionally, the support structure 122 may include portions 123a that extend beyond the portions 123b. The portions 123a contact the ground surface when the tile 100 is in an installed configuration.

[0021] Referring also to FIG. 5, in some embodiments, passages 124 may be defined within the support structure 122. The passages 124 may improve the drainage underneath the floor tile 100. Passages 124 may also facilitate additional aspects of the tile 100, for example, allowing for tubing or wiring to pass under the floor tile 100. The tubing or wiring may be contained within passages 124. In some embodiments, the passages 124 may span the entire width of bottom surface 120, in lieu of any support structure 122, e.g., as is the case with channel tiles 200, described in greater detail below

[0022] As noted above, marginal faces 103 extend around the perimeter of the tile 100, and may be generally perpendicular to the top surface 110. In some embodiments the marginal face 130 may be offset from top surface 110 at a non-perpendicular angle. Marginal faces 130 extend past the bottom surface 120 of the floor tile 100 and may form a part of the support structure 122. In some embodiments, marginal face 130 may be of variable height, as shown in FIG. 5.

[0023] In the illustrated embodiment, tile 100 has a generally rectangular shape, although it will be understood by those of skill in the art that tile 100 may resemble a variety of shapes, such as generally triangular, trapezoidal, pentagonal, hexagonal, and octagonal.

[0024] In some embodiments, the tile 100 is configured to couple to other tiles 100 and/or tile components. For example, FIG. 3 illustrates a tile system showing a first tile 100a coupled to a second tile 100b and tile channels 200a and 200b. A tile channel 200 is illustrated in FIGS. 4 and 5 and is substantially similar to floor tile 100, except as specifically noted and/or shown, or as would be inherent. For uniformity and brevity, reference numbers from 200 to 299 may be used to indicate elements corresponding to those discussed above numbered from 100 to 199 (e.g., top surface 210 corresponds generally to the top surface 110, faces 230 correspond generally to the respective faces 130, et cetera), though with any noted, shown, or inherent deviations.

[0025] As illustrated in FIG. 5, tile channel 200 may have a bottom surface 220 which is generally planar. Tile channel 200 may vary from tile 100 in that tile channel 200 may not include a supporting structure or any portion which extends outward from the bottom surface 220. This may be desired in order to create a larger passage underneath the tile channel 200 for wiring, piping, drainage, or any other system which may be installed below tile channel 200.

[0026] The second tile 100b in FIG. 3 is coupled to edge pieces 300a, 300b, and 300c. Edge pieces 300 are illustrated in FIGS. 6 and 7. As shown in FIG. 6, edge piece 300 may include a top surface 310 which includes a generally planar portion and a portion 330 which is angularly offset from horizontal.

[0027] To facilitate coupling of floor tiles 100, tile channels 200 and/or edge pieces 300, floor tiles 100 and tile channels 200 may have at least one male coupler 140 (FIG. 8) and at least one female coupler 150 (FIG. 9). Preferably, floor tiles 100 and tile channels 200 may have a plurality of male couplers 140 and female couplers 150. Although not necessary, the male couplers 140 may be disposed along two adjacent sides 130 of a tile 100, with female couplers 150 being disposed along the remaining two adjacent sides 130. Alternatively, male couplers 140 may be disposed along two opposing sides 130 of a tile 100, with female couplers 150 being disposed along the remaining two opposing sides 130. Of course, where the tile 100 includes more or less than four sides, each side may have male couplers 150 or female couplers 140. The tile channels 200 may include one or more male couplers 240 disposed along a first long edge, with one or more female couplers 250 disposed along an opposing second long edge. Short edges of the tile channels 200 may or may not include couplers 240 and/or 250.

[0028] As shown in FIG. 6, each edge piece 300 may include at least one male coupler 340 or at least one female coupler 350 along a long edge (or along a straight edge, if it's a corner edge piece). Accordingly, edge pieces 300 may be particularly configured to attach to a side of a tile having either a male coupler 340 or a female coupler 350. In some embodiments, each short edge of the edge pieces 300 may additionally include a male coupler 340 or a female coupler 350, and preferably may include a male coupler 340 on one short edge and a female coupler 350 on the opposing short edge, to facilitate coupling of the edge piece along the perimeter of the tiles 100.

[0029] Referring now to FIG. 8, a male coupler 140 is illustrated with a tile 100. Male couplers 140 may extend outward from marginal face 130 of tile 100. Preferably, the male couplers 140 may extend perpendicularly from the marginal face 130, although it may be advantageous for the couplers 140 to extend at a non-perpendicular angle from the marginal face 130. In FIG. 4, the male couplers 140 do not extend the entire height of the marginal face 130. However, it will be understood by those of skill in the art that the male couplers 140 may extend along the entire height of the marginal face 130.

[0030] Each male coupler 140 may include a central portion and at least one aperture 142 for connecting with a corresponding female coupler 150. Preferably, each male coupler 140 has a plurality of apertures 142.

[0031] It shall be understood that a male coupler 240, 340 on a tile channel 200 or an edge piece 300, respectively, is substantially similar to the male coupler 140 described herein. For example, tile channels 200 (FIGS. 4 and 5) may have a male coupler 240 which is substantially similar to, and performs substantially the same function, as male coupler 140. Edge pieces 300 (FIGS. 6 and 7) may similarly have a male coupler 340 which performs substantially the same function as male couplers 140, but includes only the central portion of the male coupler and does not include any apertures.

[0032] Referring to FIG. 9, a female coupler 150 is illustrated with a tile 100. It shall be understood that a female coupler 150 on a tile channel 200 or an edge piece 300 is substantially similar to that described herein. The female couplers 150 are configured to be complimentary to the male couplers 140, such that floor tiles 100 may be coupled together to form a tile system. Female couplers 150 may include at least one arm 152 extending from bottom surface 120 of the floor tile 100, and preferably two opposing arms 152a and 152b. Each arm 152 has a proximal end 154, a distal end 156, and at least one notch 158 on an inside face of an elbow 153 of the arm 152.

[0033] As shown in FIG. 9, the arms 152 may have two notches 158a and 158b. The notices 158a and 158b may not be colinear. In other words, the first notch 158a may be generally inwardly offset as compared to the second notch 152b. Unlike a single notch, the double notch may allow for floor tiles 100 to be installed over an uneven surface so that if a tile 100 is slightly elevated compared to an adjacent tile 100, the first notch 158a may engage with a corresponding male coupler 140 of the adjacent tile 100. If the neighboring tiles 100 are on the same level, the second notch 158b may engage with the corresponding male coupler 140 of the adjacent tile 100. Thus, it shall be understood that adjacent tiles 100 may be adjoined on different horizontal planes depending on which notch 158a or 158b is engaged between respective male and female couplers 140 and 150. Although in the illustrated embodiments, the arms 152 have two notches, it will be understood by those of skill in the art that arms 152 may have any number of notches 158, and may therefore be able to engage with male coupler 140 at a plurality of heights.

[0034] The arms 152 may be positioned inside of the marginal face 130. Additionally, as shown in FIG. 1, the top surface 110 may extend over the female coupler 150. This may allow the respective marginal faces 130 of adjacent tiles 100 to more closely abut.

[0035] Moving on, FIG. 11 illustrates a spring tab 160 disposed along the marginal face 130 of a floor tile 100. The spring tab 160 may have an exterior face 162 and a slot 166. Preferably, floor tile 100 has a plurality of spring tabs 160 disposed along the marginal face 130. Spring tabs 160 create a gap between adjacent tiles 100. The creation of a gap between tiles 100 may allow for a small amount of deformation during impacts. Furthermore, the gap created by spring tabs 160 may allow for expansion or contraction of the floor tiles 100 when subject to extreme temperatures, thereby minimizing the likelihood of component failure.

[0036] In the illustrated embodiment, the exterior face 162 of spring tab 160 is generally planar and is substantially parallel to the marginal face 130. However, in some embodiments, the exterior face 160 may not be generally planar, and instead may be concave, convex, or angled.

[0037] The spring tabs 160 may be constructed from the same material as the other components of floor tile 100. However, it may be beneficial to construct the spring tabs 160 from a different material than that of the rest of floor tile 100. For example, a more flexible material, in conjunction with various shapes of the spring tabs 160, may provide a more desirable level of impact dispersion and/or temporary deformation.

[0038] It shall be understood that tile channels 200 may optionally additionally include spring tabs 160.

[0039] FIG. 11 illustrates another embodiment of a floor tile 400 that is substantially similar to floor tile 100, except as specifically noted and/or shown, or as would be inherent. Further, those skilled in the art will appreciate that the embodiment 100 (and thus the embodiment 400) may be modified in various ways, such as through incorporating all or part of any of the described embodiments, for example. For uniformity and brevity, reference numbers from 400 to 499 may be used to indicate elements corresponding to those discussed above numbered from 100 to 199 (e.g., top surface 410 corresponds generally to the top surface 110, faces 430 correspond generally to the respective faces 130, et cetera), though with any noted, shown, or inherent deviations.

[0040] Tile 400 may have at least one projection 412 having a proximal end 414 and a distal end 416 and extending from the top surface 410. Preferably, tile 400 may have a plurality of projections 412 extending from the top surface 410. Projections 412 may provide increased resistance against shifting of artificial turf or any other material which may be placed upon the top surface 410. Even without a material atop the tile 400, the projections 412 may friction to the top surface 410 to prevent slippage, e.g., of a person moving atop the tile 400 or a vehicle driving atop the tile 400.

[0041] In the illustrated embodiment, projections 412 have a general triangular prism shape. However, it will be understood by those of skill in the art that projections 412 may be any shape, including rectangular, conical, cylindrical, pyramid, et cetera.

[0042] It may be advantageous for the at least one projection 412 to form part of a coupling mechanism with any surface material that may be applied to the tile 100. For example, a corresponding recess may be provided in the turf backing or other surface material. In this configuration, the risk of uncontrolled movement of the applied turf may be significantly minimized. However, even with corresponding recesses, the projections 412 may greatly reduce unwanted shifting of the material atop the tile 400. Further, the projections 412 may reduce or even eliminate the need for adhesives to be applied between the tile 400 and any surface material, which may reduce the time required for installing a tile and surface material systema and further allow for easier maintenance of the system.

[0043] The projections 412 may be molded (e.g., via injection molding, co-injection molding, overmolding, multi-material injection molding, etc.) as part of the floor tile 400. The projections 412 may be molded via a removable insert which may be added or removed to the tile mold during the molding process. This may be beneficial, as it allows for a variation in design or functionality of the tiles without the need for bespoke molds.

[0044] Many different arrangements of the various components depicted, as well as components not shown, are possible without departing from the spirit and scope of the present disclosure. Embodiments of the present disclosure have been described with the intent to be illustrative rather than restrictive. Alternative embodiments will become apparent to those skilled in the art that do not depart from its scope. A skilled artisan may develop alternative means of implementing the aforementioned improvements without departing from the scope of the present disclosure.

[0045] It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations and are contemplated within the scope of the claims. Not all steps listed in the various figures need be carried out in the specific order described.
