The grooves and projections have a matching dovetail cross-section, and the thrust element is held in place inside the frame by a vertical screw (30) inserted through the top (12) of the frame.

Description

La présente invention concerne un châssis et élément d'appui et d'usure pour châssis de patin à roues en ligne destiné à être interposé entre deux flancs latéraux dudit châssis, entre deux roues adjacentes, généralement centrales, pour la pratique d'un patinage dit "agressive" et plus particulièrement pour assurer le glissement transversal du patin sur un élément longiligne.The present invention relates to a frame and support and wear element for inline skate frame intended to be interposed between two lateral sides said chassis, between two adjacent wheels, generally central, for the practice of an "aggressive" skating and more particularly to ensure the transverse sliding of the skate on a long element.

De tels éléments permettent la réalisation de figures ou la pratique de glissades, par exemple sur des rambardes d'escaliers, rails,...etc.Such elements allow the realization of figures or the practice of slides, for example on stair railings, rails, ... etc.

Des éléments d'appui et d'usure de ce type sont connus et sont constitués par un bloc présentant une forme sensiblement parallélépipédique, comportant dans le sens longitudinal, deux surfaces en forme de portion de cylindre permettant le passage des roues adjacentes.Support and wear elements of this type are known and are constituted by a block having a substantially parallelepiped shape, comprising in in the longitudinal direction, two cylinder-shaped surfaces allowing the passage of adjacent wheels.

Il est connu qu'un tel élément d'usure soit fixé sur le châssis au moyen d'une vis horizontale traversant transversalement, à la fois les flancs latéraux du châssis et l'élément proprement dit, en vue de solidariser l'ensemble.It is known that such a wear element is fixed to the chassis by means of a horizontal screw crossing transversely, both the lateral flanks of the chassis and the element itself, in order to secure the assembly.

Par ailleurs, l'élément d'usure comporte également de manière connue, à son extrémité inférieure, une surface d'appui sensiblement horizontale, en alignement avec les bords inférieurs des flasques latéraux.Furthermore, the wear element also comprises, in a known manner, at its lower end, a substantially horizontal bearing surface, in alignment with the lower edges of the lateral flanges.

Bien que ces derniers soient également reliés entre eux par les axes d'une pluralité de roues en ligne, l'expérience montre néanmoins que la pratique d'un tel sport, dans les conditions énoncées ci-dessus, provoque d'une part l'usure progressive, non seulement de la pièce d'usure sur ses bords latéraux en direction transversale, mais également celle des bords inférieurs des flasques latéraux. Ceci conduit à la longue à ce que la surface d'appui se réduise à une simple arête.Although these are also interconnected by the axes of a plurality of wheels in line, experience nevertheless shows that the practice of a such sport, under the conditions set out above, causes wear on the one hand progressive, not only of the wear part on its lateral edges in direction transverse, but also that of the lower edges of the lateral flanges. This leads in the long run that the support surface is reduced to a simple edge.

Cet inconvénient a été précédemment résolu par la demanderesse en proposant une pièce d'appui et d'usure qui est munie, du côté de son extrémité destinée à servir de surface d'appui, d'une fente longitudinale permettant de supprimer l'arête centrale due à l'usure et de garantir toujours la présence d'au moins deux surfaces d'appui latérales.This drawback was previously resolved by the plaintiff in proposing a support and wearing part which is provided, on the side of its end intended to serve as a bearing surface, a longitudinal slot allowing remove the central edge due to wear and always guarantee the presence of minus two lateral bearing surfaces.

Mais l'usage a révélé également un autre problème résidant dans le fait que les bords inférieurs des flasques latéraux, non seulement s'usent, mais s'arrachent également sous la violence des chocs liés à ce type de sport, car c'est sur ces bords des flasques que les angles sont attaqués dans un sens ou dans l'autre. But usage has also revealed another problem, that lower edges of the side flanges not only wear out, but tear off also under the violence of the shocks linked to this type of sport, because it is on these edges flanges that the angles are attacked in one direction or the other.

Ceci peut se comprendre aisément par le fait que la fixation de l'élément d'appui et d'usure est effectuée uniquement par une vis horizontale s'étendant transversalement à travers les flasques latéraux et ledit élément d'appui, à une certaine distance des bords inférieurs de ces flasquesThis can be easily understood by the fact that the fixing of the element support and wear is carried out only by a horizontal screw extending transversely through the lateral flanges and said support element, at a certain distance from the lower edges of these flanges

On aurait pu imaginer résoudre ce problème en déplaçant cette vis horizontale au maximum vers le bas, de manière à consolider la liaison des flasques à proximité de ses bords inférieurs, mais on comprend aisément que dans ce cas, on limite notablement la marge d'usure de la pièce d'appui, car on rencontrera rapidement la vis horizontale évoquée ci-dessus.We could have imagined solving this problem by moving this horizontal screw as far down as possible, so as to consolidate the connection of the flanges to near its lower edges, but we can easily understand that in this case, we significantly limits the wear margin of the support piece, because we will encounter quickly the horizontal screw mentioned above.

La présente invention a pour but de remédier aux inconvénients évoqués ci-dessus en proposant une pièce de glissement et d'usure améliorée, en ce sens qu'elle comporte des moyens de fixation sur le châssis qui sont constitués par des glissières verticales ménagées en vis-à-vis de part et d'autre des surfaces internes des flancs et coopérant avec des rainures correspondantes réalisées sur deux faces opposées latérales de l'élément d'appui et d'usure, de manière que son montage coulissant sur lesdits flancs assure simultanément, d'une part, sa liaison auxdits flancs, et, d'autre part, la liaison entre eux, dans le sens transversal, des flancs du châssis, sans moyen accessoire, pour constituer avec le châssis un ensemble monobloc et cohérent.The object of the present invention is to remedy the drawbacks mentioned above by proposing an improved sliding and wearing part, in this sense that it comprises means for fixing to the chassis which are constituted by vertical slides arranged opposite either side of the internal surfaces sidewalls and cooperating with corresponding grooves made on two faces lateral opposites of the support and wear element, so that its mounting sliding on said sides simultaneously ensures, on the one hand, its connection to said flanks, and, on the other hand, the connection between them, in the transverse direction, of the flanks of the chassis, without additional means, to form an assembly with the chassis monobloc and coherent.

La présente invention concerne également les caractéristiques qui ressortiront au cours de la description qui va suivre et qui devront être considérées isolément ou selon toutes leurs combinaisons techniques possibles.The present invention also relates to the characteristics which will emerge during the description which follows and which should be considered in isolation or according to all their possible technical combinations.

Cette description, donnée à titre d'exemple non limitatif, fera mieux comprendre comment l'invention peut être réalisée, en référence aux dessins annexés sur lesquels :

  • la figure 6 est une vue en coupe transversale selon la ligne VI-VI de la figure 3,
  • la figure 7 est une vue en coupe selon la ligne VII-VII de la figure 3.
This description, given by way of nonlimiting example, will make it easier to understand how the invention can be implemented, with reference to the accompanying drawings in which:
  • FIG. 1 is a perspective view of a chassis intended to receive a support and wear element according to the invention, before its assembly,
  • FIG. 2 is a perspective view from below of a chassis according to FIG. 1,

Les figures 1 et 2 montrent un châssis 10 de patin à roues en ligne de type classique, c'est-à-dire de section transversale en forme de U et comportant deux flasques latéraux 11 reliés entre eux par une ou plusieurs surfaces d'appui horizontales 12.Figures 1 and 2 show an inline skate frame 10 of the type classic, i.e. U-shaped cross section with two lateral flanges 11 interconnected by one or more bearing surfaces horizontal 12.

Sur ce châssis 10, sont montées de façon connue en soi, des roues 14, 15 à l'aide d'axes 13.On this frame 10, are mounted in a manner known per se, wheels 14, 15 using axes 13.

La pièce d'usure 20 est traditionnellement montée sur le châssis entre les deux roues centrales 14 et présente une forme sensiblement parallélépipédique, comportant latéralement, en direction longitudinale, deux surfaces 21 en forme de portion de cylindre pour le passage des roues adjacentes 14.The wear part 20 is traditionally mounted on the chassis between the two central wheels 14 and has a substantially parallelepiped shape, comprising laterally, in the longitudinal direction, two shaped surfaces 21 cylinder portion for the passage of adjacent wheels 14.

Selon l'invention, ledit élément d'appui et d'usure 20 comporte des moyens de fixation sur le châssis 10 qui sont constitués par des glissières verticales 22, ménagées en vis-à-vis de part et d'autre des surfaces internes 11a des flancs 11 dudit châssis et coopérant avec des rainures correspondantes 23 réalisées sur deux faces opposées latérales 24 de l'élément d'appui et d'usure 20, de manière que son montage coulissant sur lesdits flancs 11 assure simultanément, d'une part, sa liaison auxdits flancs, et, d'autre part, la liaison entre eux, dans le sens transversal, des flancs 11 du châssis 10, sans moyen accessoire, pour constituer avec le châssis 10 un ensemble monobloc et cohérent.According to the invention, said support and wear element 20 comprises means for fixing to the frame 10 which are constituted by vertical slides 22, formed opposite each other on the internal surfaces 11a of the sides 11 of said chassis and cooperating with corresponding grooves 23 produced on two opposite lateral faces 24 of the support and wear element 20, so that its sliding mounting on said sides 11 simultaneously ensures, on the one hand, its connection to said sides, and, on the other hand, the connection between them, in the direction transverse, of the sides 11 of the chassis 10, without accessory means, to constitute with the chassis 10 a one-piece and coherent assembly.

De ce fait, une liaison entre eux des flancs du châssis est réalisée sur toute la hauteur de ces derniers et permet d'éviter les phénomènes d'arrachement des flasques au moins dans la zone de liaison.Therefore, a connection between them of the sides of the chassis is made over the entire height of the latter and avoids the phenomena of tearing of flanges at least in the connection area.

Comme le montrent particulièrement bien l'ensemble des figures, et selon un exemple préféré de réalisation, les glissières 22 et les rainures 23, respectivement des flancs 11 du châssis 10 et dudit élément 20, ont des sections complémentaires en forme de queue-d'aronde.As all the figures show particularly well, and according to a preferred embodiment, the slides 22 and the grooves 23, respectively sides 11 of chassis 10 and of said element 20 have complementary sections in the shape of a dovetail.

Selon un mode de réalisation préféré, les sections en forme de queue-d'aronde d'au moins un élément ont un profil décroissant en direction du bord inférieur du châssis de façon à avoir un effet de coincement entre la pièce d'usure 20 et les flancs du châssis lors de sa mise en place et rattrapper ainsi les jeux de fabrication. According to a preferred embodiment, the dovetail-shaped sections at least one element has a decreasing profile towards the bottom edge of the chassis so as to have a wedging effect between the wear part 20 and the sides of the chassis during its installation and thus catch up with the manufacturing clearances.

Selon une autre caractéristique intéressante de l'invention, l'élément d'appui et d'usure 20 comporte des moyens complémentaires de fixation qui sont constitués par une vis verticale 30 prenant appui sur une face supérieure d'une paroi horizontale 12 du châssis 10 et venant en prise avec ledit élément 20 sur lequel il agit en traction contre une face inférieure de ladite paroi 12, de manière à l'immobiliser dans le sens vertical.According to another advantageous characteristic of the invention, the support element and wear 20 comprises additional fixing means which are constituted by a vertical screw 30 bearing on an upper face of a horizontal wall 12 of the chassis 10 and engaging said element 20 on which it acts in traction against a lower face of said wall 12, so as to immobilize it vertically.

Bien entendu, la vis verticale 30 aura une longueur adéquate, préalablement déterminée, afin d'assurer une fixation efficace par rapport au châssis, tout en réservant audit élément d'appui et d'usure 20, un talon largement dimensionné pour offrir un maximum de matériau d'usure, non traversé par la vis 30.Of course, the vertical screw 30 will have an adequate length, beforehand determined, to ensure effective attachment to the chassis, while reserving for said support and wear element 20, a largely dimensioned heel to offer a maximum of wear material, not crossed by the screw 30.

Selon une autre caractéristique de l'invention, l'élément d'appui et d'usure présente à son extrémité libre opposée à la vis de fixation 30 et destinée à constituer une surface d'usure, une surface concave 25 de rayon prédéterminé.According to another characteristic of the invention, the support and wear element present at its free end opposite the fixing screw 30 and intended to constitute a wear surface, a concave surface 25 of predetermined radius.

De même, les flancs latéraux 11 du châssis 10 présentent sur leurs bords inférieurs libres, des évidements concaves 26, ménagés en coïncidence avec la surface concave 25 dudit élément 20.Likewise, the lateral flanks 11 of the chassis 10 have on their edges lower free, concave recesses 26, arranged in coincidence with the concave surface 25 of said element 20.

Bien entendu, de nombreux perfectionnements pourraient être apportés au mode de réalisation qui vient d'être cité, comme par exemple l'élément d'appui et d'usure qui pourrait très bien comporter une fente longitudinale disposée de façon médiane par rapport à sa surface inférieure, de manière à fournir deux surfaces d'appui, comme connu dans l'art antérieur évoqué dans le préambule.Of course, many improvements could be made to the embodiment which has just been cited, such as for example the support element and wear which could very well include a longitudinal slot arranged median to its bottom surface, so as to provide two bearing surfaces, as known in the prior art mentioned in the preamble.
