Definitions

  • This invention relates to tiles for covering playground surfaces.
  • the stirface 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 tech- nique 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 indivi ⁇ dual damaged tiles is a difficult problem.
  • tile which can be laid on top of a level ground surface.
  • a ramp edge can be laid around the tiled area to provide a smooth gradual transition from the surrounding ground surface to the tile surface.
  • These tiles provide only limited energy absorbtion under impact due to their rela- tively 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. The length of the studs is several times the thickness of the upper sheet, and the tile as a whole has such a- hickness 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.
  • the present invention has for its broad aim to eliminate, or at least significantly .reduce the disadvant ⁇ ages of the known tiles as elucidated above.
  • the invention resides in a surface tile of rubber or other similar resiliently defortnable material, comprising an upper sheet and integral projections extending from the underside of the sheet, the projections being hollow and capable of collapsing by buckling under impact against the upper tile surface.
  • the same energy absorbtion performance can be achieved with projections of much shorter length than the solid studs used in the prior art tiles, and without forfeiting the support given to the sheet under normal loading.
  • the projections are cylindrical and have a length substantially less than their diameter.
  • the projections are arranged in a regular array with their centres located at the corners of a pattern of squares .
  • the invention resides in a fixin member in combination with a surface tile of rubber or other similar resiliently deformable material, 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 annular engaging part of the fixing member is preferably circular and dimensioned to fit tightly around a projection.
  • 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 present invention provides an edge strip for use with a surface tile of rubber or other resiliently deformable material, the strip being of a similar material 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 novel feature of the edge strip resides in each end thereof being angled substantially at 135 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 and -5 , respectively, to the - _ -
  • edge strip 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.
  • a second novel feature of the 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 lat, and to prevent articles being forced under the edge.

  • Figures 19, 20 and 21 are sections taken along the lines XIX - XIX, XX - XX and XXI - XXI, respectively, of Figure l ⁇ .
  • 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 strip*are fastened securely to the ground by ground fixing members located at the positions indicated by the letters A and B in Figure 1.
  • tile 1 is formed as a rubber moulding and as may be seen from Figures 2 to . has a generally flat upper sheet -. from the underside of which extend project ⁇ ions 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 0 mm with the upper sheet having a thickness of about _ ⁇ to ' 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 ., but the walls of the pro ⁇ jections can buckle under a shock loading to cushion the impact and provide gradual energy absorbtion.
  • a moulded rubber edge strip 2 is shown in detail in Figures 9 to 11.
  • each end of the strip is inclined to the inner edge at 135 . 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 and -__. to the inner edge. These 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 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.
  • An alternative form of 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 he 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 l6 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.
  • fixing members may be used for each tile (up to the total number of projections ) as may be considered appropriate, but a few located at suitable positions should be adequate.
  • Some members 15 may De 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 replace ⁇ ment of a damaged tile.
  • a fixing member is shown in Figure 8 engaged with projections of two abutting tiles.
  • the modified tile illustrated in Figures 13 to 17 differs to that of Figures 2 to 'i in that it has a peripheral skirt 30 depending from the upper sheet, 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 lock ⁇ ing engagement in these members.
  • each projection 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 8 which are joined to the rim 17 «
