Abstract

The tiles formed flexibly of plastics or natural material by moulding has a lower plate (3) which is rigid or semi-rigid encased in the body of the tile. The upper part (4) has at least one layer (5) of parallel cavities (6) opening at different parts of the tile (1) to produce the necessary flexibility to damp impacts. There can be several layers (5,7) of openings which can alternate with respect to the lower layer. The tiles can be placed directly on the ground and held in place by their weight.

Description

The present invention relates to flexible slabs serving as a shock absorber for sport both indoors and on the ground making it possible to make passables, reception mattresses, carpets, etc.

In sporting matters, the use of floorboards, approved carpets, reception mattresses, various mats used as shock absorbers, made of foam of different densities, the design and construction method does not allow the configuration of the surface, on the other hand the achievements are bulky and difficult to transport.

The invention aims to overcome the drawbacks described above.

The subject of the invention is flexible slabs serving as a shock absorber in synthetic or natural material produced by molding each having a rigid or semi-rigid plate in the lower part molded and in the upper part at least one series of plies of recesses parallel opening on either side of the slab intended to generate the necessary flexibility depending on the destination of the damping, in the case of several series of recess plies, the latter are alternated by plies, according to the desired embodiments, the slabs are laid on the ground and are held together, or are held on the lateral sides by crosspieces penetrating into the external recesses of the lateral and / or transverse slabs, or said slabs are placed inside a perimeter beforehand Finished.

Other characteristics and advantages of the invention will emerge more clearly from the description which follows, given with reference to the accompanying drawings given by way of nonlimiting example where - Figure 1 is a perspective view of a flexible slab serving damper of small thickness having a series of plies of parallel recesses, - Figure 2 is a sectional view of the slab shown in Figure 1, - Figure 3 is a perspective view of a flexible slab serving as a damper double series in parallel recess plies, - Figure 4 is a sectional view of the slab shown in Figure 3, - Figure 5, an installation of slabs, the latter being simply placed on the ground, - Figure 6 , a partial top view of a lateral edge of a slab receiving a retaining crosspiece through a recess, - Figure 7, a sectional view of a periphery holding the slabs.

As shown in FIGS. 1 and 2, a flexible molded slab serving as a damper 1 of small thickness made of synthetic or natural material, comprises in its lower part 2 a mass plate 3 embedded in the mass of material, said plate 3 being rigid or semi-rigid ferrous or non-ferrous material, in the upper part 4 of the slab 1 is provided a ply 5 of parallel recesses 6 opening on either side of said slab, the ply 5 of recesses 6 being intended to generate the flexibility necessary for the desired amortization.

As shown in Figures 3 and 4, the slab 1A differs from the slab 1 shown in Figure 1 at the level of the ply 5 of parallel recesses 6, said ply being doubled by a ply 7 whose parallel recesses 6 are alternated with respect to the recesses of the lower ply 5. Without departing from the scope of the invention and depending on the thickness of the slab produced, the latter can advantageously be provided with several plies of parallel recesses 6, said recesses 6 being alternated between each ply.

As shown in Figure 5, the tiles 1, 1A, .. are placed directly on the ground and their retention in place being achieved by their own weight and it is obvious that this method of maintenance is a function of the desired use because as represented FIG. 6, the tiles 1, 1A, can be maintained by means of lateral crosspieces 8 threading into the recesses 6 peripheral of the embodiment, in the case of tiles 1A with a double ply of recesses 6 the support can be reinforced by transverse crosspieces 9 threading into the peripheral recesses 6 of the second ply.

According to Figure 7, the tiles 1, 1A, .. are arranged inside a peripheral edge 10 corresponding to the desired embodiment and similarly said tiles 1, lA, .. can be distributed in a pit.

Claims (2)

CLAIMS 1 ") Flexible slabs serving as a shock absorber in synthetic or natural material produced by molding characterized in that a slab has at the bottom (2) a rigid or semi-rigid plate (3) embedded in the mass of material in part upper (4) at least one ply (5) of parallel recesses (6) opening on either side of said slab (1, 1A) generating the flexibility necessary for the desired damping. 20) Flexible tiles serving as a shock absorber according to claim 1, characterized in that in the case of several plies (5, 7) of parallel recesses (6), said parallel recesses (6) are alternated with respect to the lower ply (5 ).  30) Flexible tiles serving as a shock absorber according to claim 1, characterized in that said tiles (1, 1A) are either placed directly on the ground and held by their own weight, or inside a peripheral stop (10) or distributed in a pit. 40) flexible tiles serving as a shock absorber according to claims 1 and 3 characterized in that the tiles (1, 1A) are held by means of lateral crosspieces (8) threading into the recesses (6) peripheral of the sheet (5) of the embodiment, or in the case of slabs (1A) by lateral (8) and transverse (9) crosspieces threading into the peripheral recesses (6) of the second ply (7).
