Definitions
- This invention relates to tiles for covering playground surfaces.
- the surface layer reduces the chances of cuts and abrasions.
- the surface layer can conveniently be applied in the form of tiles of rectangular, especially square shape.
- This fixing technique has the disadvantages that great care is needed when laying the tiles to ensure that they abut tightly together and no gaps which would collect dirt and form trip points are left. Furthermore, replacement of individual damaged tiles is a difficult problem.
- EP-A-117707 discloses a floor mat assembled from a number of tiles of grid like structure. The tiles have edge formations enabling them to be interlocked with each other, ramp strips being provided for the edge of the mat. These tiles provide only limited energy absorption under impact due to their relatively small thickness.
- An alternative form of tile having better energy absorbing characteristics consists of a flat upper sheet or pad from the lower side of which projects a multiplicity of integral conical studs.
- DE-A-2614095 discloses a floor tile of resilient material having hollow rectangular elements open at their bottom faces.
- GB-A-1122009 discloses a tile having a perforated upper sheet provided with cylindrical projections on the underside. Half projections are formed at the edges of the tiles so that adjacent tiles can be securely fastened together by a connector.
- the length of the projections found in the prior art is several times the thickness of the upper sheet, and the tile as a whole has such a thickness that it is not ideal for laying directly on top of the ground surface, and it is usually necessary to provide a shallow excavation enabling the tiles to be sunk into the ground. This is normally done so that the tile surface is level with the surrounding ground.
- the need for the ground to be prepared in this way is a drawback, especially if the tiles are to be laid at an already existing playground.
- the enhanced energy absorption is achieved by the projections which on impact become progressively compressed in the direction of their length.
- the present invention has for its broad aim to eliminate, or at least significantly reduce the disadvantages of the known tiles as elucidated above.
- a surface tile particularly for playground surfaces
- the tile being formed of resiliently deformable material and comprising an upper sheet and integral projections in the form of hollow cylinders open at the lower ends thereof extending from the underside of the sheet, the projections being capable of collapsing by buckling under an impact against the upper surface of the sheet thereby to cushion the impact characterised in that the length of the projections is substantially less than the diameter thereof.
- the same energy absorption performance can be achieved with projections of much shorter length than the projections used in the prior art tiles, and without forfeiting the support given to the sheet under normal loading.
- the projections are arranged in a regular array with their centers located at the corners of a pattern of squares.
- a fixing member may be provided for fixing the tile to an underlying surface, the fixing member comprising a first part adapted to be fixed securely to the ground and a second, annular part for engaging a projection on the underside of the tile to attach the tile securely to the ground.
- the tiles have part projections at the edges thereof, and the fixing member is capable of engaging part projections of adjacent tiles for holding the tiles in close abutment as well as fixing them to the ground.
- the engaging part, and possibly the tile projection can be provided with a locking tooth-like projection.
- the first part may be adapted, e.g. by the provision of holes, to be fixed to the ground by bolts or other fasteners.
- the tiles can be fixed securely in position for normal purposes, but they are easier to replace and easier to lay than tiles stuck down with adhesive.
- An edge strip may be provided for use with the surface tile of the invention, the strip being of a similar material to the tile and being arranged to be fixed against a free edge of the tile to provide a transition between the tile and an adjacent ground surface.
- One feature of the preferred edge strip resides in each end thereof being angled substantially at 135 o to the inner edge of the strip, and having areas of reduced thickness defining lines along which the strip can be cut, said lines extending at angles of substantially 90 o and 45 o , respectively, to the inner edge. With such an edge strip the same strip can be used, by severing the end along a cut line if necessary, to form a straight connection between an internal corner or an external corner with an adjacent edge strip.
- Another feature of the preferred edge strip resides in an outer edge portion normally projecting beyond the lower face of the strip, whereby the edge portion is stressed into abutment with the ground when the edge strip is fixed to the ground.
- the stressing of the edge portion helps prevent gaps, e.g. if the ground is not perfectly flat, and to prevent articles being forced under the edge.
- FIG. 1 Illustrated in Figure 1 is a playground tile layout, the tiles being laid on the top of a level ground surface. As shown there are five tiles 1 of identical construction to each other. Extending around the tiles is a continuous ramp edge or square edge formed from identical edge strips 2 as will be described in more detail below. The tiles and edge strips are fastened securely to the ground by ground fixing members located at the positions indicated by the letters A and B in Figure 1.
- Each tile 1 is formed as a rubber moulding and as may be seen from Figures 2 to 4 has a generally flat upper sheet 4 from the underside of which extend projections 5 arranged in a regular array.
- the projections consist of hollow cylinders open at their lower ends and arranged with their centres at the corners of a pattern of squares.
- Half-projections are located at the tile edges, with quarter projections at the corners, the arrangement being such that each tile edge has the same appearance as the other three edges. When two tiles are placed together the half-projections combine to form complete cylindrical projections, and when the corners of four tiles are placed together the quarter-projections define a complete cylinder, as will be apparent from Figure 1.
- the tile may have a thickness of around 50 mm with the upper sheet having a thickness of about 1 2 to 1 3 the length of the projections.
- the diameter of the projections is substantially greater than, e.g. 2 to 3 times, their length. Under normal loads the projections 5 provide firm support for the sheet 4, but the walls of the projections can buckle under a shock loading to cushion the impact and provide gradual energy absorption.
- a moulded rubber edge strip 2 is shown in detail in Figures 9 to 11. It includes half cylindrical projections 7 along its inner edge, arranged to register with the half-projections of a tile 1 against which the edge strip is located, and a downwardly sloping side wall 8 for providing a gradual transition from the top surface of the adjacent tile to the surrounding ground surface.
- Each end of the strip is inclined to the inner edge at 135 o , so that two strips can be positioned against adjacent edges of a tile and define a continuous ramp surface around the external corner e.g. as indicated at positions X in Figure 1.
- the strip 2 is moulded with V-grooves 9, 10, or the like, extending along lines at 90 o and 45 o to the inner edge.
- V-grooves define predetermined cut lines. Two strips cut along grooves 9 can be laid in a straight line, as indicated at positions Y in Figure 1, and two strips cut along grooves 10 can define an internal corner ramp section as indicated at Z in Figure 1. Thus only one form of strip is needed to provide a continuous ramp edge around a tile layout, whatever the perimeter shape.
- the side wall 8 includes a wedge shaped free edge portion 12 which projects beyond the lower face of the edge strip 1, so that when the strip is fixed to the ground the portion 12 is stressed and presses down against the ground. This ensures that the edge fits tightly against the ground to prevent ingress of dirt under the edge strip and prevents articles being pushed under the edge strip. If required the undersurface of the edge portion 12 can be affixed to the ground with adhesive.
- edge strip is shown in Figure 12. It differs from that of Figures 9 to 11 in that it has a vertical outer side wall 13 instead of a sloping wall. This strip is intended to be used when the tiles are to be recessed into a cavity and it obviates the need for a surrounding timber or concrete up-stand which would otherwise be required.
- ground fixing members 15 one of which is shown in Figures 5 to 7. It can be formed as a plastics or hard rubber moulding and consists of an annular base 16 with an upstanding circular rim 17 having an internal diameter to make a tight fit around the tile projections. On the inside of the rim a locking tooth 18 is provided for gripping the projection.
- the base includes a pair of projecting lugs 19 with holes 20 intended for bolting the member to the ground. After the member 15 has been fixed to the ground a tile projection is forced down into the rim 17 to fasten the tile securely to the around.
- many fixing members may be used for each tile (up to the total number of projections 5) as may be considered appropriate, but a few located at suitable positions should be adequate.
- Some members 15 may be used merely to hold adjacent tiles together, such as that at position B in Figure 1, without being fixed to the ground.
- the fixing members shown at positions A in Figure 1 are bolted to the ground. They are located at the tile edges and they engage the co-operating part projections of the edge strips and tiles for securing both to the ground. Although the tiles and edge strips are held very securely by the fixing members they can be forced away, e.g. for replacement of a damaged tile.
- a fixing member is shown in Figure 8 engaged with projections of two abutting tiles. As well as fixing the tiles to the ground the fixing member holds them in tight abutment.
- the modified tile illustrated in Figures 13 to 17 differs to that of Figures 2 to 4 in that it has a peripheral skirt 30 depending from the upper sheet, the depth of the skirt being substantially less than the length of the projections, and cruciform webs 31 interconnecting the four projections centred at the corners of each square.
- the webs stiffen the upper ends of the projections to improve the energy absorbing characteristics and the skirt helps prevent sharp tools being forced between and under the tiles in an unauthorised attempt to remove them.
- the projections 5 are tapered at their lower ends to facilitate insertion into the gripping members, and are provided with peripheral grooves 33 to assist their locking engagement in these members.
- each projection for accommodating radial spokes 36 of the modified ground fixing member which is shown in Figures 18 to 21.
- the fixing member has a frusto-conical hub 37 which is located centrally within the rim and connected to it by the spokes 36.
- the lugs 19 are formed with upstanding edges 38 which are joined to the rim 17.
