- This lighter colored top layer of the tile may be about one-half (1 ⁇ 2) inch in thickness, and the remainder bottom portion of the tile may be black and made from shredded or pulverized conventional black walled automobile tires.
- Tiles formed with such a lighter colored top layer may be about twenty percent (20%) cooler, or more, on its top surface than tiles formed completely from conventional black walled automobile tires.

- This application is a continuation-in-part of U.S. application Ser. No. 12/799,784, filed on Apr. 30, 2010, and entitled “Interlocking Rubber Tiles for Playgrounds”, the disclosure of which is incorporated herein by reference and on which priority is hereby claimed, which prior application is based on U.S. Provisional Application Ser. No. 61/215,087, which was filed on May 1, 2009, and is entitled “Interlocking Rubber Tiles For Playgrounds”, and U.S. Provisional Application Ser. No. 61/279,975, which was filed on Oct. 28, 2009, and is entitled “Interlocking Rubber Tiles For Playgrounds”, the disclosure of each of which is hereby incorporated by reference and on which priority is hereby claimed.
- 1. Field of the Invention
- This invention generally relates protective padding and more particularly relates to recycled protective tiling.
- 2. Description of the Prior Art
- The most common injuries at recreational facilities such as playgrounds and athletic or sporting arenas are attributed to falls. Such injuries include head trauma, fractures and sprains, some leaving long term disability. Children very often run on concrete slabs or loose gravel, while others play on swings, carrying them high above the ground. During incidents in which the child loses control or balance, the ground material can prove to be very unforgiving.
- Conventional methods of minimizing injury from falls include padding the ground with dense material such as closed cell foam. This type of padding commonly comes in lengthy sheets that are cut to size. The sheets are placed over the ground, regardless of the composition. For example, closed cell foam pads are often placed over loose gravel in the same manner that they are placed over concrete slab. Unfortunately, the underlying ground material can affect the overall effectiveness of the protective padding.
- Closed cell foam pads most typically have a planar bottom and top without any recesses. While this conventional design provides means for effectively positioning and maintaining coverage of a concrete slab, if the same foam pad is placed on loose gravel or rocks, it will not be secured and may cause further personal injury from movement of the protective covering. Additionally, when closed cell foam pads are placed on uneven surfaces such as gravel, the foam pads take the shape of the underlying surface, creating an uneven activity area that may provoke falls from tripping. Conventional closed cell foam padding also tends to become slippery when wet from inclement weather or nearby sprinklers as water commonly pools on the flat surface thereof.
- There are also conventional tiles available that are made from reprocessed or recycled rubber, for example, from shredded rubber automobile tires. However, such conventional tiles do not interlock with one another and may separate, or buckle, leaving either an exposed area of the supporting surface on which the tiles are laid, or an uneven surface, which may cause injury to a child playing on the tiled surface. Also, if conventional non-interlocking tiles are installed on a rooftop, they may be unsafe and may cause injury because of the potential flight characteristics of such tiles resulting from high wind conditions.
- When conventional tiles are placed next to each other, even if they were somehow glued together, there may be a tendency for the tiles to curl at their edges, possibly caused by temperature fluctuations or use. Such curling may result in an uneven surface and may cause injury to a person walking or running thereon.
- The present invention provides a novel rubberized padding device that overcomes the inherent disadvantages found in the conventional designs.
- It is an object of the present invention to provide rubberized tiles (which also include rubberized mats, blocks and pavers) for use in covering sports and recreational areas, playgrounds or the like, as well as rooftops, which interlock with one another.
- It is another object of the present invention to provide rubberized, interlocking tiles which include structure that acts as a reservoir for containing glue to adhesively join adjacent tiles together.
- It is still another object of the present invention to provide rubberized tiles which interlock with one another, and which include structure that acts as a reservoir for containing glue to adhesively join adjacent tiles together, and further include structure that allows excess glue to be removed from the reservoir.
- It is yet a further object of the present invention to provide interlocking tiles that include structure which helps minimize separation, curling and peeling of the edges of the tiles.
- It is yet another object of the present invention to provide interlocking tiles for use with playgrounds, rooftop surfaces and the like made from reprocessed or recycled rubber which overcome the inherent disadvantages of known tiles.
- It is still another object of the present invention to provide interlocking tiles which may be installed on rooftops and which satisfy wind uplift criteria.
- In accordance with one form of the present invention, a tile for covering an area and which interlocks with an adjacent tile includes a main body having a top surface and a bottom surface disposed opposite the top surface. The main body has at least a first lateral side and a second lateral side.
- The tile includes at least one male connector situated on at least one of the first lateral side and the second lateral side of the main body and extending outwardly therefrom. The tile further includes at least one female receptacle situated on at least one of the first lateral side and the second lateral side of the main body.
- The male connector of the tile is engageable with a female receptacle of an adjacent tile so that the tile may interlock with the adjacent tile.
- Preferably, the male connector and the female receptacle include structure defining a reservoir for containing an adhesive for adhesively securing the tile and an adjacent tile together.
- In another embodiment, the tile further includes structure defining at least one slot (that is, an elongated recess or opening) situated on at least one of the first and second lateral sides of the main body. The tile also includes at least one corresponding projection situated on a opposite lateral side of the tile from where the at least one slot is located. The projection of the tile is received by a corresponding slot of an adjacent tile. When adjacent tiles are mated together, the engagement of the projection with the slot helps strengthen the connection between the tiles and minimizes the lateral sides of the adjacent tiles from curling upwardly or separating.
- These and other objects, features and advantages of the present invention will be apparent from the following detailed description of illustrative embodiments thereof, which is to be read in connection with the accompanying drawings.

FIGS. 1-9 of the drawings, it will be seen that a rubber tile protective system constructed in accordance with a first embodiment of the present invention includes a plurality ofrubber tiles 2, eachrubber tile 2 being interconnectable to another by a series of interlocking mechanisms integrated along the peripheral edges of each tile. Therubber tiles 2 may be selectively coupled by the interlocking mechanisms to one another to form a customizable protective surface of various proportion and size, depending on the specific application and area to be protected. - Each
tile 2 may be formed in a plurality of shapes and sizes, but preferably is rectangular. Thetile 2 includes amain body 3 residing generally in a plane and having atop surface 4 having a high coefficient of friction for providing sufficient traction to children and other users. Themain body 3 of thetile 2 also includes an oppositely disposedbottom surface 6, thebottom surface 6 being laid on and resting on the ground or other supporting surface and having a recessedportion 8 formed therein. A plurality ofcylindrical stanchions 10 extending downwardly and outwardly from the recessedportion 8, theend face 12 of eachstanchion 10 being coplanar with thebottom surface 6 of thetile 2, provide gripping means to resist movement of thetile 2 when the ground surface consists of loose materials such as gravel, pebbles or shale. More specifically, when thetiles 2 are placed on a ground surface consisting of loose materials, the loose ground material may fill the recessed area around thestanchions 10 and thestanchions 10 may anchor thetile 2 in place. Each end face 12 of thestanchions 10 defines a flat bottom surface that is coplanarly aligned with thebottom surface 6 of thetile 2 to provide a large surface area to grip flat ground materials such as concrete slab. - Along the periphery of the
main body 3 of therubber tiles 2 are situated a plurality of interlocking mechanisms comprising amale connector 14 and a matingfemale receptacle 16. More specifically, along a first lateral side and neighboring second lateral side of themain body 3 of thetile 2 are extending outwardly therefrom a series ofmale connectors 14. Disposed oppositely of themale connectors 14, along a third lateral side and neighboring fourth lateral side of themain body 3, are extending outwardly therefrom a series offemale receptacles 16.Individual rubber tiles 2 may be joined together by cooperatively mating themale connectors 14 on the first and second lateral side of afirst tile 2 with thefemale receptacles 16 on the third or fourth lateral side of a second tile. To provide structural support, thetiles 2 are preferably joined together in a staggered manner, as shown inFIG. 1 . - Now referring to
FIGS. 3 , 4, 4 a, 6 and 7 of the drawings, it can be seen that eachmale connector 14 is formed as an L-shaped member extending perpendicularly outwardly from the side of thetile 2. Themale connector 14 includes a horizontally disposedfirst segment 18, which extends co-planarly with themain body 3, and a vertically disposedsecond segment 20, thesecond segment 20 extending perpendicularly from thefirst segment 18. Thefirst segment 18 further includes atop surface 22 having aglue reservoir 24 formed as a recess therein for receiving liquid adhesive. A plurality ofmale connectors 14 are preferably formed in series along the first and second sides of thetile 2, theconnectors 14 preferably being equidistant from one another. - The
female receptacles 16, as illustrated inFIGS. 3 , 5, 5 a and 5 b of the drawings, are formed asrectangular recesses 26 within thebottom surface 6 of thetile 2, along the third and fourth sides thereof. Therecesses 26 are defined by aninner wall 28, an oppositely disposedouter wall 30, twoside walls 32 and a recessedsurface 33. Theinner wall 28 is connected to the oppositely disposedouter wall 30 by the twoside walls 32, theinner wall 28 extending from the recessedportion 8 of thebottom surface 6 and terminating in anend wall 34 that is coplanar to thebottom surface 6, and theouter wall 30 extending from the recessedsurface 33 of thefemale receptacle 16 and terminating in anend wall 36, theouter wall 30 being shorter than theinner wall 28 to accommodate and engage the horizontalfirst segment 18 andtop surface 22 thereof of an alignedmale connector 14 of anadjacent tile 2. Thefemale receptacles 16 are preferably formed in series along the third and fourth sides of thetile 2, eachfemale receptacle 16 preferably being positioned opposite from its correspondingmale connector 14 on the first and second sides. Therecesses 26 cooperatively receive the verticalsecond segment 20 of themale connector 14, mating themale connector 14 and thefemale receptacle 16 andinterlocking neighboring tiles 2. The recessed surface 33 (within the recess 26) of eachfemale receptacle 16 also has formed therein aglue reservoir 38 as a recess for receiving liquid adhesive, theglue reservoir 38 being similar in shape to theglue reservoir 24 formed in themale connector 14. - Each of the
outer wall 30 of thefemale receptacle 16 and the verticalsecond segment 20 of themale connector 14 further includes a vertically disposedslot 40, whichslots 40 are aligned with one another when theconnector 14 is received by thereceptacle 16. Thevertical slot 40 of the verticalsecond segment 20 of themale connector 14 is in fluid communication with theglue reservoir 24 formed in themale connector 14 to allow excess adhesive filling the reservoir to flow through thevertical slot 40 from themale connector 14. Similarly, thevertical slot 40 of theouter wall 30 of thefemale receptacle 16 is in fluid communication with theglue reservoir 38 formed in thefemale receptacle 16 to allow excess adhesive filling thereservoir 38 to flow through thevertical slot 40 from thefemale receptacle 16. - Each
inner wall 28 of thefemale receptacles 16 further includes a vertically disposedchannel 50 formed therein, as shown inFIGS. 5 , 5 a, 5 b and 16. Thevertical channel 50 of eachinner wall 28 extends from theglue reservoir 38 of thefemale receptacle 16 through theend wall 34 thereof. Eachvertical channel 50 of eachinner wall 28 is in communication with theglue reservoir 38 andrecess 26 formed in thefemale receptacle 16 to allow excess adhesive filling thereservoir 38 to flow through thevertical channel 50 from thefemale receptacle 16, especially when two tiles are joined together and placed right-side up. In a preferred embodiment, thevertical channel 50 of theinner wall 28 is oppositely situated to thevertical slot 40 of theouter wall 30 of eachfemale receptacle 16. - Prior to interlocking two neighboring
tiles 2, a liquid adhesive is applied to one or both of the horizontalfirst segment 18 and/orglue reservoir 24 of eachmale connector 14 and therecess 26 and/orglue reservoir 38 of eachfemale receptacle 16. As the alignedmale connector 14 andfemale receptacle 16 ofadjacent tiles 2 are mated and pressure is applied, the alignedvertical slots 40 in theouter wall 30 of thefemale receptacle 16 and the verticalsecond segment 20 of themale connector 14 create a path for excess adhesive to exit the 24, 38 of theglue reservoirs male connectors 14 andfemale receptacles 16 and the sides of the joined togethertiles 2. Excess glue will also escape thefemale receptacle 16 through thechannel 50 formed in theinner wall 28 of thefemale receptacle 16 and will flow downwardly towards the ground and away from the top surface of the tile when the tiles are joined together and positioned with the top surface properly facing upwardly. Thus, the 40, 50 will help minimize or prevent any adhesive from adhering to the top surface of the tile, which would otherwise have required its removal therefrom, which is difficult to do because of the rough surface texture of the tile. The adhesive secures the verticalchannels second segment 20 of themale connector 14 within therecess 26 of thefemale receptacle 16 and preferably secures thetop surface 22 of the horizontalfirst segment 18 of themale connector 14 to theend wall 36 of theouter wall 30 of thefemale receptacle 16. - The
top surface 4 of eachtile 2 preferably further includes a plurality ofwater channels 42. Thewater channels 42 are preferably formed as chamfers along the top peripheral edges of thetile 2. As neighboringtiles 2 are interlocked, their facing peripheral chamfered edges create such a recess orchannel 42 that allows water to run off thetop surface 4 of thetile 2 into thechannel 42, minimizing water pooling.Additional water channels 44 may be formed as elongated recesses in thetop surface 4, each being in fluid communication with an aforementionedperipheral water channel 42. -
FIGS. 10-19 illustrate a second embodiment of the rubber tile protective system of the present invention. As in the embodiment described previously and shown inFIGS. 1-9 , the protective system formed in accordance with this second embodiment also preferably includes a plurality ofinterconnectable rubber tiles 2, eachtile 2 having amain body 3, atop surface 4, abottom surface 6, a plurality ofcylindrical stanchions 10, and a plurality of interlocking mechanisms comprising amale connector 14 and a matingfemale receptacle 16, and other components described previously with respect to the first embodiment, with like reference numbers used herein designating the same or similar structures. - However, in this second embodiment, the
tile 2 includes one or more slots 17 (that is, elongated recesses or openings) formed in at least one lateral side thereof, and one or moreelongated projections 15 formed on at least another lateral side of thetile 2 which is preferably situated opposite the side having the slot orslots 17 formed therein. In a preferred form, thetile 2 includes a plurality ofslots 17 spaced apart from each other, each slot being positioned on a side of the tile between adjacentmale connectors 14, as shown inFIG. 12 of the drawings. Alternatively, one or moreelongated projections 15 may be situated on this side between themale connectors 14 instead of theslots 17. - Correspondingly, in this preferred form, the
tile 2 includes a plurality ofelongated projections 15 spaced apart from each other, each projection being positioned on a side of the tile that is preferably opposite the side having theslots 17, as shown inFIG. 13 of the drawings. Eachprojection 15 is preferably situated on the side between adjacentfemale receptacles 16. Alternatively, one ormore slots 17 may be situated on this side between thefemale receptacles 16 instead of theprojections 15. - When two
tiles 2 are placed adjacent one another, with the side of one tile which includesprojections 15 facing the side of the other tile which includesslots 17, theprojections 15 andslots 17 should be positioned on their respective sides so that they are in alignment and may mate with one another, theprojections 15 of one tile being received by correspondingslots 17 of the other tile. Adhesive may be applied to either or both of theprojections 15 andslots 17 further to secure the tiles together. - If the
tile 2 is rectangular in shape, in that it includes two opposite shorter sides and two opposite longer sides, such as shown inFIG. 10 , then it is preferred to have the two shorter sides formed with theprojections 15 on one shorter side and theslots 17 on the other shorter side. It is the shorter sides of the tile that tend to curl, rather than the longer sides, and thus theprojections 15 andslots 17 are most needed on the shorter sides of the tile. However, it is envisioned to be within the scope of the present invention to have all of the sides of thetile 2 formed with oppositely disposedprojections 15 andslots 17. Alternatively, adjacent sides of the tile may be formed with either a plurality ofprojections 15 or a plurality ofslots 17, or each of one or more sides of the tile may include an alternating or mixed pattern ofprojections 15 andslots 17. -
Individual rubber tiles 2 formed in accordance with the second embodiment shown inFIGS. 10-19 may also be joined together by cooperatively mating themale connectors 14 on the first and second lateral sides of afirst tile 2 with thefemale receptacles 16 on the third and fourth lateral sides of a second tile. In this second embodiment of the tile, theprojections 15 of onetile 2 also cooperatively mate with theslots 17 of asecond tile 2. The mating of theprojections 15 and theslots 17 strengthens the connection between the first andsecond tiles 2. The engagement of theprojections 15 andslots 17 also reduces the tendency of the lateral sides of the tile to curl upwardly or separate and helps maintain thetop surfaces 4 of the joined together tiles in a common plane. - It is also envisioned to be within the scope of the present invention to fasten the
tiles 2 to a supporting surface, such as asphalt or wood, by using screws orother fasteners 54 which pass through the thickness of themale connectors 14 preferably at the horizontalfirst segments 18 thereof and into the supporting surface, with or without the use of liquid adhesive betweenmating tiles 2. For this purpose, a countersunkrecess 52 may be formed in theglue reservoir 24 of the horizontalfirst segment 18 of one or moremale connectors 14 to facilitate locating where the screw orfastener 54 should be placed, as shown inFIGS. 14 , 15 and 18. - The
tiles 2 of the first and second embodiments may be formed from reprocessed or recycled rubber, for example, from shredded or pulverized rubber automobile tires. In another form of the present invention, a top layer or portion of each tile may be formed from EPDM (ephylene propylene diene monomer) granules or shredded or pulverized white, gray or yellow (i.e., light colored) rubber tires, such as those found on forklifts and other rubber wheeled equipment. This lighter colored top layer of the tile may be about one-half (½) inch in thickness, and the remainder bottom portion of the tile may be black and made from shredded or pulverized conventional black walled automobile tires. Tiles formed with such a lighter colored top layer may be about twenty percent (20%) cooler, or more, on its top surface than tiles formed completely from conventional black walled automobile tires. - The interlocking rubber tiles are described herein as being particularly useful for playgrounds. However, it should be realized that the tiles have many different uses, including, for example, for covering rooftop surfaces and other athletic and recreational surfaces.
- Although illustrative embodiments of the present invention have been described herein with reference to the accompanying drawings, it is to be understood that the invention is not limited to those precise embodiments, and that various other changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit of the invention.
