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 the plates used for the production of sports mats, plates which delimit arches and which are joined to other identical or similar plates extending, on the one hand, in the longitudinal direction and, on the other hand, in the transverse direction.
- the invention is based on the observation that the junction parts between two contiguous plates delimiting several vaults must be as solid as the junction between two successive vaults of the same plate but also have the same flexibility as regards concerns the junction of the adjoining plates 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 a contiguous plate extending transversely with respect 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 openings in the form of discontinuous chevrons 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.
- some of the parts of the plates located between the openings 5 form protruding cords 8 constituting reinforcements.
- the number of cords 8 can vary, that is to say that a bead 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 bristle of hairs does not end in a point, however, but in a row of bristles 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 the 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 P and the same goes for step 19 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 or greenness of the protruding 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
- 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 a plate each time opposite another plate by aligning them so that the eyes 11 are placed above the legs 12 which protrude from below the top of the vaults 4.
- 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 of so that the body 24 of the split rivet is spread and locked in the lugs 12 while the head 25 of the rivet is supported on the top of each arch 4. It is advantageous to provide the split rivets 22 of a color different from that of the plates which allows, if necessary, to check if certain rivets have been damaged or have escaped during the use of the track.
- 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 nature depending on whether said plates are to be used inside or outside or even when they are subject to the action of ultraviolet rays in the mountains.

Abstract
Description
La présente invention concerne les tapis de sport et, plus particulièrement, ceux qui sont destinés à être utilisés pour la constitution de pistes de ski.The present invention relates to sports mats and, more particularly, those which are intended to be used for the constitution of ski slopes.
D'une manière plus particulière, l'invention concerne les plaques utilisées pour la réalisation de tapis de sport, plaques qui délimitent des voûtes et qui sont réunies à d'autres plaques identiques ou similaires s'étendant, d'une part, dans le sens longitudinal et, d'autre part, dans le sens transversal.More particularly, the invention relates to the plates used for the production of sports mats, plates which delimit arches and which are joined to other identical or similar plates extending, on the one hand, in the longitudinal direction and, on the other hand, in the transverse direction.
L'une des difficultés majeures qui est apparue au cours de l'utilisation de tapis de sport comportant des plaques du genre de celles utilisées ci-dessus réside dans la liaison devant être réalisée, d'une part, entre les plaques s'étendant dans le sens longitudinal et, d'autre part, entre les plaques s'étendant dans le sens transversal. Il est apparu que les agrafes mises en oeuvre jusqu'à présent peuvent se détacher et qu'ainsi des plaques peuvent laisser un espace libre entre elles ou être amenées à se chevaucher. Elles créent, de toute façon, un risque pour les skieurs lorsqu'elles sont désaccouplées car un ski peut s'engager entre deux plaques.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 appeared that the staples used up to now can come off and that in this way the plates can 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.
L'invention est partie de la constatation que les parties de jonction entre deux plaques contigües délimitant plusieurs voûtes devaient être aussi solides que la jonction entre deux voûtes successives d'une même plaque mais aussi présenter la même souplesse en ce qui concerne la jonction des plaques contigües dont les voûtes sont alignées afin qu'il n'y ait pas de solution de continuité, tant dans la résistance du tapis réalisé que dans sa souplesse.The invention is based on the observation that the junction parts between two contiguous plates delimiting several vaults must be as solid as the junction between two successive vaults of the same plate but also have the same flexibility as regards concerns the junction of the adjoining plates whose vaults are aligned so that there is no solution of continuity, both in the resistance of the carpet produced and in its flexibility.
L'invention résout ce problème.The invention solves this problem.
Conformément à l'invention, les plaques pour la constitution de tapis de sport et en particulier de pistes de ski, lesdites plaques étant constituées par une succession de voûtes sur lesquelles font saillie des doigts ou poils et en dessous desquelles font saillie les doigts d'appui engagés directement dans le sol ou dans un tapis de sol intermédiaire, les voûtes délimitant en outre des ouvertures, sont caractérisées en ce qu'un côté latéral de chaque plaque présente des oeils au sommet de certaines au moins des voûtes tandis que l'autre côté délimite des pattes pouvant être glissées sous les voûtes d'une plaque contigüe s'étendant transversalement par rapport à la première, l'un des bords terminaux de chaque plaque étant muni d'anneaux saillants et l'autre bord terminal d'ardillons introduits dans les anneaux saillants pour assurer la liaison des plaques successives dans le sens longitudinal.According to the invention, 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 a contiguous plate extending transversely with respect 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.
Diverses autres caractéristiques de l'invention ressortent, d'ailleurs, de la description détaillée qui suit.Various other characteristics of the invention will emerge from the detailed description which follows.

A la fig. 1, deux plaques 1 et 2 devant être assemblées dans le sens longitudinal du tapis à réaliser sont représentées de façon schématique. D'autres plaques identiques sont prévues pour être assemblées dans une direction perpendiculaire après ou avant l'assemblage dans la direction longitudinale. Les plaques reposent de préférence sur un tapis de sol 3 qui cependant n'est pas nécessaire. Lorsqu'on utilise un tapis de sol, celui-ci est constitué en matière imputrescible, par exemple par des fils entremêlés de matière synthétique, pour former une sorte de feutre ou de matelas analogue à du crin enchevêtré. Les plaques 1 délimitent de manière connue en elle-même des arceaux ou voûtes 4 dans lesquels sont pratiquées des ouvertures 5 en forme de chevrons discontinus, chaque chevron s'étendant par exemple sur une amplitude correspondant sensiblement à deux arceaux successifs.In fig. 1, two
Les ouvertures en forme de chevrons discontinus laissent libres, tant sur les côtés latéraux 6 que sur les côtés terminaux 7, des espaces pleins qui forment une ceinture périphérique à chaque plaque, ce qui est bien visible à la fig. 2. En outre, au moins, certaines des parties des plaques se trouvant entre les ouvertures 5 forment des cordons saillants 8 constituant des renforts. Le nombre de cordons 8 peut varier, c'est-à-dire qu'un cordon peut être formé à chaque fois entre deux ouvertures 5 contigües ou bien seulement en alignement avec des segments continus isolant deux ouvertures 5 contigües. Des doigts ou poils 9 sont formés sur la partie pleine des voûtes successives de la manière illustrée par la fig. 2, c'est-à-dire sur des zones également en forme de chevrons s'imbriquant les unes dans les autres. Il a été trouvé avantageux que chaque chevron de poils ne se termine cependant pas en pointe mais suivant une rangée de poils 9a respectivement 9b présentant plusieurs doigts ou poils de front. Les rangées 9a, 9b sont arrêtées de préférence à une certaine distance du sommet d'une voûte ce qui évite que certains doigts ou poils soient très courts ou, au contraire, que d'autres soient très longs ce qui aurait pour effet de créer des flexibilités trop variables entre les doigts ou poils. En effet, le sommet de tous les doigts ou poils s'étend dans un même plan. Outre ce qui précède, il est avantageux que les côtés latéraux 6 et terminaux 7 soient bordés par une nervure périphérique 10 augmentant la raideur desdits côtés. Cependant, la nervure des côtés latéraux, c'est-à-dire celle qui borde les voûtes, est avantageusement arrêtée peu après le sommet de chaque voûte afin de ne pas réduire exagérément la flexibilité de ces voûtes. Comme l'illustre toujours la fig. 2, chaque plaque forme au sommet de chaque voûte un oeil 11 qui borde la partie des nervures périphériques 10 correspondantes qui fait saillie au-dessus desdites voûtes. Les oeils 11 sont formés sur un côté latéral seulement de chaque plaque, l'autre côté formant une patte 12 qui fait saillie depuis le dessous de chaque voûte.The openings in the form of discontinuous chevrons leave free, both on the
La jonction de chaque voûte présente une nervure de renfort 13 faisant saillie en dessous de la plaque, comme illustré à la fig. 4', et à partir de cette nervure des doigts d'appui 14. Les doigts d'appui 14 sont par exemple cylindriques et ils forment à leur extrémité une tête conique 15 pour délimiter une barbe d'ancrage facilitant la tenue de la plaque dans le sol ou dans le tapis de sol 3. La nervure de renfort 13 qui se trouve sur l'un des côtés terminaux de chaque plaque, celle qui est désignée par 13a à la fig. 4, forme des anneaux saillants 16 qui s'étendent ainsi dans le plan le plus bas de chaque voûte. Il est avantageux que les anneaux saillants 16 soient placés en alignement avec certains des cordons saillants 8 de façon qu'ils se trouvent placés dans des zones à résistance particulièrement élevée des voûtes.The junction of each arch has a reinforcing
Le second côté terminal de chaque plaque forme sur son dessous des ardillons 17 présentant deux redans 18 et 19 décalés angulairement et en hauteur. Le redan 18 s'étend sur environ 180P et il en est de même du redan 19 mais lesdits deux redans sont diamétralement opposés. Les redans 18 et 19 sont formés à partir d'un corps cylindrique 20 dont le diamètre n'est que très légèrement inférieur à celui de l'ouverture des anneaux saillants 16.The second end side of each plate forms on its
Comme l'illustre la fig. 5, les ardillons 17 sont terminés de la même façon que les doigts d'appui 14 par une partie conique 21 dont la grande base forme le redan 18. Pour assembler des plaques dans le sens longitudinal, on pose tout d'abord au sol ou sur le tapis de sol 3 par exemple la plaque 2 (fig. 1), on engage ensuite dans les anneaux saillants 16 de cette plaque 2 les ardillons 17 de la plaque 1. Ceci s'effectue facilement en présentant la plaque 1 de manière qu'elle soit légèrement inclinée par rapport à la plaque 2 déjà posée de sorte que le redan 18 est facilement franchi et que le redan 19 est ensuite franchi par flexion de la matière constitutive de chaque ardillon 17. En fin d'engagement, chaque ardillon 17 se trouve par rapport à chaque anneau 16 dans la position illustrée par la fig. 5. Etant donné les raidisseurs que constituent les nervures de renfort 13 et la nervure périphérique 10, la liaison existant entre deux plaques consécutives est extrêmement rigide, particulièrement si les ardillons 17 sont relativement rapprochés par exemple d'une mesure de l'ordre de 6 à 7 cm. Lorsque plusieurs plaques ont été assemblées de même manière dans le sens longitudinal, d'autres plaques sont assemblées dans le sens transversal. Pour cela il suffit d'amener à chaque fois une plaque en regard d'une autre plaque en les alignant de façon que les oeils 11 se trouvent placés au-dessus des pattes 12 qui font saillie depuis le dessous du sommet des voûtes 4. On introduit alors, comme l'illustre la fig. 6, un rivet fendu 22 dans chaque oeil et chaque patte puis on fait coulisser dans le rivet fendu un noyau 23 qu'il comporte de façon que le corps 24 du rivet fendu soit écarté et verrouillé dans les pattes 12 tandis que la tête 25 du rivet prend appui sur le dessus de chaque voûte 4. Il est avantageux de prévoir les rivets fendus 22 d'une couleur différente de celle des plaques ce qui permet, le cas échéant, de vérifier si certains rivets ont été endommagés ou se sont échappés dans le cours de l'usage de la piste.As illustrated in fig. 5, the
Comme cela ressort de ce qui précède, l'assemblage dans le sens longitudinal des plaques est effectué au niveau le plus bas de chaque voûte qu'elle délimite tandis que l'assemblage transversal est réalisé au niveau le plus haut des voûtes. De cette manière les efforts qui sont appliqués aux plaques et qui tendraient à les écarter sont répartis dans deux plans différents de sorte que les éléments de liaison et les voûtes travaillent un peu à la manière des parois opposées d'un caisson et assurent une grande homogénéité dans les déformations que subissent les voûtes dont le sommet tend toujours à être déformé davantage que la partie inférieure puisque l'effort des skis s'exerce plus directement sur le sommet. Outre ce qui précède, on met à profit comme l'illustre la fig. 2 certaines au moins des zones dans lesquelles ne sont pas formés des doigts ou poils 9 pour délimiter un croisillon 26 facilement déformable et servant à la mise en place de pièces de jalonnage, par exemple des bâtons de slalom. Les croisillons 26 sont formés au sommet des voûtes de sorte qu'ils n'amoindrissent pas la résistance des plaques et, par ailleurs, les bâtons de slalom ou autres pièces de jalonnage peuvent simplement être introduits dans les croisillons 26 et reposer sur le sol sans y être introduits pour que leur tenue soit faible et qu'elle ne risque pas ainsi de blesser un skieur lors d'une manoeuvre.As is apparent from the above, the assembly in the longitudinal direction of the plates is carried out at the lowest level of each vault which it delimits while the transverse assembly is carried out at the highest level of the vaults. In this way the forces which are applied to the plates and which would tend to separate them are distributed in two different planes so that the connecting elements and the arches work a little like the opposite walls of a box and ensure great homogeneity in the deformations that the vaults undergo, the top of which always tends to be deformed more than the lower part since the force of the skis is exerted more directly on the top. In addition to the above, use is made of as illustrated in FIG. 2 at least some of the zones in which fingers or
L'invention n'est pas limitée à l'exemple de réalisation représenté et décrit en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the embodiment shown and described in detail, because various modifications can be made without departing from its scope.
En particulier, les plaques peuvent être moulées en différentes matières dont le choix dépend de leur utilisation, le technicien mettant nécessairement en oeuvre des matières de nature différentes suivant que lesdites plaques doivent être utilisées ou non à l'intérieur ou à l'extérieur ou encore lorsqu'elles sont sujettes à l'action des rayons ultraviolets en montagne.In particular, the plates can be molded from different materials, the choice of which depends on their use, the technician necessarily using materials of different nature depending on whether said plates are to be used inside or outside or even when they are subject to the action of ultraviolet rays in the mountains.
