Definitions
- the present invention relates to sports mats and, more particularly, those which are intended to be used for the constitution of ski slopes.
- the invention relates to plates, according to the preamble of claim 1, used for the production of sports mats, plates which delimit arches and which are joined to other identical or similar plates s' extending, on the one hand, in the longitudinal direction and, on the other hand, in the transverse direction.
- Such plates are known from FR-A-2349680.
- One of the major difficulties which has arisen during the use of sports mats comprising plates of the kind of those used above resides in the connection to be made, on the one hand, between the plates extending in the longitudinal direction and, on the other hand, between the plates extending in the transverse direction. It has become apparent that the staples used so far may come loose and that in this way the plates may leave a free space between them or be caused to overlap. In any case, they create a risk for skiers when they are uncoupled because a ski can engage between two plates.
- the invention is part of the observation that the joining parts between two contiguous plates delimiting several arches had to be as solid as the junction between two successive arches of the same plate but also have the same flexibility as regards the joining of the plates contiguous whose vaults are aligned so that there is no solution of continuity, both in the resistance of the carpet produced and in its flexibility.
- the invention solves this problem.
- the plates for constituting sports mats and in particular ski slopes said plates being constituted by a succession of arches on which protrude fingers or hairs and below which protrude the fingers of support engaged directly in the ground or in an intermediate floor mat, the vaults further delimiting openings, are characterized in that a lateral side of each plate has eyes at the top of at least some of the vaults while the other side delimits legs which can be slid under the vaults of an adjoining plate extending transversely to the first, one of the end edges of each plate being provided with projecting rings and the other end edge of barbs introduced in the protruding rings to ensure the connection of the successive plates in the longitudinal direction.
- FIG. 1 two plates 1 and 2 to be assembled in the longitudinal direction of the mat to be produced are shown schematically. Other identical plates are provided to be assembled in a perpendicular direction after or before assembly in the longitudinal direction.
- the plates preferably rest on a floor mat 3 which, however, is not necessary.
- a floor mat is used, it is made of rot-proof material, for example by threads interwoven with synthetic material, to form a sort of felt or mattress similar to tangled hair.
- the plates 1 delimit in a manner known per se arches or arches 4 in which are made openings 5 in the form of discontinuous chevrons, each chevron extending for example over an amplitude corresponding substantially to two successive arches.
- the discontinuous chevron-shaped openings leave free, both on the lateral sides 6 and on the terminal sides 7, solid spaces which form a peripheral belt on each plate, which is clearly visible in FIG. 2.
- the parts of the plates located between the openings 5 form protruding cords 8 constituting reinforcements.
- the number of cords 8 may vary, that is to say that a cord can be formed each time between two contiguous openings 5 or else only in alignment with continuous segments isolating two contiguous openings 5.
- Fingers or bristles 9 are formed on the solid part of the successive arches as illustrated in FIG. 2, that is to say on areas also in the form of chevrons overlapping one another.
- each chevron of hairs does not end in a point, however, but in a row of hairs 9a respectively 9b having several fingers or bristles at the front.
- the rows 9a, 9b are preferably stopped at a certain distance from the top of a vault which avoids that certain fingers or hairs are very short or, on the contrary, that others are very long which would have the effect of creating too variable flexibilities between fingers or hair. Indeed, the top of all fingers or hairs extends in the same plane.
- it is advantageous for the lateral 6 and terminal 7 sides to be bordered by a peripheral rib 10 increasing the stiffness of said sides.
- each plate forms at the top of each vault an eye 11 which borders the part of the corresponding peripheral ribs 10 which projects above said vaults.
- the eyes 11 are formed on only one lateral side of each plate, the other side forming a tab 12 which projects from the underside of each arch.
- each arch has a reinforcing rib 13 projecting below the plate, as illustrated in FIG. 4, and from this rib of the support fingers 14.
- the support fingers 14 are for example cylindrical and they form at their end a conical head 15 to define an anchoring beard facilitating the holding of the plate in the floor or in the floor mat 3.
- the reinforcing rib 13 which is located on one of the end sides of each plate, that which is designated by 13a in fig. 4, forms protruding rings 16 which thus extend in the lowest plane of each arch. It is advantageous that the projecting rings 16 are placed in alignment with some of the projecting cords 8 so that they are placed in areas with particularly high resistance of the vaults.
- each plate forms on its underside barbs 17 having two steps 18 and 19 offset angularly and in height.
- the step 18 extends over approximately 180 ° and it is the same with step 1.9 but said two steps are diametrically opposite.
- the steps 18 and 19 are formed from a cylindrical body 20 whose diameter is only very slightly less than that of the opening of the projecting rings 16.
- the barbs 17 are terminated in the same way as the bearing fingers 14 by a conical part 21, the large base of which forms the step 18.
- the plate 2 fig.1
- engaging in the projecting rings 16 of this plate 2 the barbs 17 of the plate 1. This is easily done by presenting the plate 1 so that 'it is slightly inclined relative to the plate 2 already laid so that the step 18 is easily crossed and that the step 19 is then crossed by bending the material of each barb 17.
- each barb 17 is located with respect to each ring 16 in the position illustrated in FIG. 5.
- the connection between two consecutive plates is extremely rigid, particularly if the barbs 17 are relatively close together, for example by a measurement of the order of 6 at 7 cm.
- other plates are assembled in the transverse direction. For this, it suffices to bring each time a plate opposite another plate by aligning them so that the eyes 11 are placed above the legs 12 which project from below the top of the vaults 4. then introduced, as illustrated in FIG.
- a split rivet 22 in each eye and each tab then a core 23 is made to slide in the split rivet 23 which it comprises so that the body 24 of the split rivet is separated and locked in the tabs 12 while the head 25 of the rivet rests on the top of each arch 4. It is advantageous to provide the split rivets 22 of a different color from that of the plates, which makes it possible, if necessary, to check whether certain rivets have been damaged or have escaped in the course of use of the track.
- a spider 26 which is easily deformable and which is used for fitting parts tramlines, for example slalom poles.
- the braces 26 are formed at the top of the vaults so that they do not reduce the resistance of the plates and, moreover, the slalom poles or other tramline parts can simply be introduced into the braces 26 and rest on the ground without be introduced so that their resistance is low and that it does not risk injuring a skier during a maneuver.
- the plates can be molded from different materials, the choice of which depends on their use, the technician necessarily using materials of different types depending on whether said plates are to be used inside or outside or when they are used. are subject to the action of ultraviolet rays in the mountains.
