Abstract

The roller blades are constituted by a chassis (5) on the upper plate (4) of which is fixed the sole (3) of a boot (2). Wheels (6) are located on the lower longitudinal part of the chassis. The chassis is composed of two parts (A,B) which are hinged together in the longitudinal or transverse direction by a deformable zone (13). This zone is associated with device for controlling its deformation which allows modification of its bending moment during skating and/or alignment of the lower plane of the wheels. The deformable zone comprises a local thinning on the upper part of the chassis near its plate and between two successive wheels. This local thinning constitutes a bending leaf and is obtained by making two vertical cuts (14) in two side chassis webs (10).

Description

La présente invention concerne un patin du type à roues en ligne constitué par un châssis, sur une platine supérieure duquel est apte à être fixée la semelle d'une chaussure et comportant une partie inférieure longitudinale sur laquelle sont disposées les roues.The present invention relates to a shoe of the in-line wheel type constituted by a chassis, on an upper plate of which is adapted to be fixed the sole of a shoe and comprising a longitudinal lower part on which the wheels are arranged.

Ce type de patin est destiné à l'entraînement des patineurs sur glace hors patinoire, mais également à tous sportifs désireux d'entretenir ou de perfectionner sur un sol dur goudronné, cimenté, etc. les techniques utilisées dans des sports de glisse tels que le ski de piste, le ski de fond, le patin à glace, etc.This type of skate is intended for the training of skaters on ice outside the ice rink, but also for all athletes wishing to maintain or improve on hard paved, cemented ground, etc. techniques used in board sports such as downhill skiing, cross-country skiing, ice skating, etc.

C'est ainsi que la pratique de ce sport comprend une phase motrice ou propulsive en faisant diverger le patin vers l'extérieur et en prenant un appui latéral sur les roues ainsi inclinées, à la manière d'une prise de carre, puis une phase de glisse s'effectuant en repositionnant les roues perpendiculairement par rapport au sol.Thus the practice of this sport includes a driving or propulsive phase by making the skate diverge outwards and taking lateral support on the wheels thus inclined, in the manner of an edge grip, then a phase sliding by repositioning the wheels perpendicularly to the ground.

La pratique d'un tel sport a naturellement dérivé vers la recherche de figures artistiques ou acrobatiques à réaliser au cours du patinage.The practice of such a sport naturally drifted towards the search for artistic or acrobatic figures to be achieved during skating.

C'est ainsi qu'il est connu des patins dont la ligne inférieure des roues décrit un arc de cercle convexe permettant ainsi au patin de ne porter que sur les roues centrales. L'inconvénient est que cet agencement est permanent et n'est pas toujours recherché. C'est le cas du patin décrit dans le brevet US 938 168 qui comporte par ailleurs des moyens de réglage de sa pointure en vue de l'adapter à une chaussure donnée.This is how skates are known, the lower line of the wheels of which describes an arc of a convex circle, thus enabling the skate to bear only on the central wheels. The disadvantage is that this arrangement is permanent and is not always sought after. This is the case of the skate described in US Pat. No. 938,168 which also includes means for adjusting its size in order to adapt it to a given shoe.

Par conséquent, l'un des buts de l'invention a été de rechercher un dispositif de contrôle de la hauteur des roues afin de pouvoir intervenir à la demande sur l'alignement des roues du patin en fonction des effets de patinage recherchés. En fait, il a été recherché de pouvoir sélectionner une position du patin dite "rocker" ou pivotante lorsque le plan inférieur des roues forme un arc de cercle et "anti-rocker" lorsque celles-ci se trouvent sur une droite, donc non pivotante.Consequently, one of the objects of the invention has been to find a device for controlling the height of the wheels in order to be able to intervene on demand on the alignment of the skate wheels according to the desired slip effects. In fact, it has been sought to be able to select a position of the pad known as "rocker" or pivoting when the lower plane of the wheels forms an arc of a circle and "anti-rocker" when the latter are on a straight line, therefore not pivoting. .

Mais dans un cas comme dans l'autre, c'est-à-dire en position "rocker" ou en position "anti-rocker", les roues sont solidaires entre elles par l'intermédiaire d'un châssis rigide.But in one case as in the other, that is to say in the "rocker" position or in the "anti-rocker" position, the wheels are secured to each other by means of a rigid chassis.

Cela conduit, dans certaine situation de patinage, sur terrain accidenté par exemple, à un mauvais confort d'utilisation.This leads, in certain skating situations, on uneven terrain for example, to poor comfort in use.

C'est pour cette raison qu'il a été recherché une polyvalence dans la conception de châssis, telle à permettre sa déformation non permanente, c'est-à-dire en le rendant libre d'adopter toute géométrie grâce à une flexibilité qui lui est conférée, ceci afin qu'il épouse le profil d'un terrain donné, tout en autorisant dans certains cas de pouvoir à l'inverse à appliquer au même patin une déformation permanente pour obtenir la position de "rocker" ou d'"anti-rocker" précitée.It is for this reason that versatility has been sought in the design of chassis, such as to allow its non-permanent deformation, that is to say by making it free to adopt any geometry thanks to a flexibility which is conferred, this so that it marries the profile of a given ground, while authorizing in certain cases of being able on the contrary to apply to the same skate a permanent deformation to obtain the position of "rocker" or "anti -rocker "above.

L'invention a pour but de résoudre ces problèmes par un châssis amélioré et concerne à cet effet un patin du type à roues en ligne constitué par un châssis, sur une platine supérieure duquel est apte à être fixée la semelle d'une chaussure et comportant une partie inférieure longitudinale sur laquelle sont disposées les roues, caractérisé en ce que le châssis est constitué par au moins deux parties reliées et/ou articulées l'une par rapport à l'autre dans la direction longitudinale et/ou transversale, par l'intermédiaire d'une zone déformable qui associée à des moyens de contrôle de sa déformabilité permet la modification de son moment fléchissant en cours de patinage et/ou de l'alignement du plan inférieur des roues du patin.The invention aims to solve these problems by an improved chassis and for this purpose relates to a shoe of the in-line wheel type constituted by a chassis, on an upper plate of which is capable of being fixed the sole of a shoe and comprising a longitudinal lower part on which the wheels are arranged, characterized in that the chassis consists of at least two parts connected and / or articulated relative to each other in the longitudinal and / or transverse direction, by the intermediate of a deformable zone which associated with means for controlling its deformability allows the modification of its bending moment during skating and / or the alignment of the lower plane of the skate wheels.

Selon une autre caractéristique de l'invention, la zone déformable du châssis est associée à des moyens de contrôle de sa déformabilité de manière à permettre la modification de son moment fléchissant en cours de patinage et/ou de l'alignement du plan inférieur des roues du patin.According to another characteristic of the invention, the deformable zone of the chassis is associated with means for controlling its deformability so as to allow the modification of its bending moment during skating and / or of the alignment of the lower plane of the wheels. skating.

Ainsi il est bien obtenu un patin offrant à la fois un confort d'utilisation et une grande maniabilité de celui-ci tout en permettant de l'adapter à certains cas de figures particuliers ou une rigidité du châssis est au contraire recherchée.Thus it is well obtained a shoe offering both comfort of use and great maneuverability thereof while allowing it to be adapted to certain specific cases where rigidity of the chassis is on the contrary sought.

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.

Le patin à roues en ligne 1 désigné dans son ensemble et représenté sur la figure 1 comprend une chaussure 2 constituée d'une semelle externe 3 destinée à être rendue solidaire de la platine supérieure 4 d'un châssis 5 sur lequel sont disposées les roues 6, semelle 3 à partir de laquelle s'étend une tige 7 recouvrant l'ensemble du pied et se prolongeant en direction de la cheville du patineur.The inline skate 1 designated as a whole and shown in Figure 1 comprises a shoe 2 consisting of an outer sole 3 intended to be made integral with the upper plate 4 of a chassis 5 on which the wheels 6 are arranged , sole 3 from which extends a rod 7 covering the entire foot and extending in the direction of the skater's ankle.

La semelle 3 de la chaussure 2 est rendue solidaire du châssis 5 formant la platine supérieure horizontale 4 sur laquelle est fixée ladite semelle 3 par l'intermédiaire de moyens de fixation, connus en soi, en l'occurrence des vis traversant la platine 4 pour se visser dans les bords latéraux de la semelle 3. Bien entendu, des moyens de fixation détachables tels que courroies, coques, etc..., peuvent également être prévus.The sole 3 of the shoe 2 is made integral with the chassis 5 forming the horizontal upper plate 4 on which said sole 3 is fixed by means of fixing means, known per se, in this case screws passing through the plate 4 for screw into the lateral edges of the sole 3. Of course, detachable fixing means such as belts, shells, etc., can also be provided.

Le châssis 5 comporte également une partie inférieure perpendiculaire à la platine 4 selon son axe longitudinal et par exemple constituée par deux ailes latérales verticales 10 parallèles entre elles et disposées de part et d'autre de son axe longitudinal.The chassis 5 also includes a lower part perpendicular to the plate 4 along its longitudinal axis and for example constituted by two vertical lateral wings 10 parallel to each other and arranged on either side of its longitudinal axis.

Les ailes latérales 10 se prolongent respectivement à leur partie supérieure par un retour perpendiculaire constituant un plan correspondant à la platine horizontale 4.The lateral wings 10 extend respectively at their upper part by a perpendicular return constituting a plane corresponding to the horizontal plate 4.

De cette manière, les ailes latérales verticales 10 définissent globalement avec la platine 4 de la chaussure 2, un U renversé entre les ailes duquel sont disposées une pluralité de roues 6, par exemple au nombre de quatre, par l'intermédiaire des axes d'articulation transversaux 12 solidaires du châssis 5 pour constituer un train roulant.In this way, the vertical lateral wings 10 define generally with the plate 4 of the shoe 2, an inverted U between the wings of which are arranged a plurality of wheels 6, for example four in number, via the axes of transverse articulation 12 integral with the chassis 5 to constitute a running gear.

Selon l'invention, le châssis 5 est constitué par au moins deux parties A et B reliées et articulées l'une par rapport à l'autre dans la direction longitudinale et éventuellement par l'intermédiaire d'une zone déformable 13.According to the invention, the chassis 5 is constituted by at least two parts A and B connected and articulated relative to each other in the longitudinal direction and possibly via a deformable zone 13.

D'une manière générale, la zone déformable 13 est constituée par un amincissement local pratiqué sur une partie supérieure du châssis 5 à proximité de sa platine 4 et entre deux roues successives 6 quelconques portées pour ledit châssis 5.In general, the deformable zone 13 is formed by a local thinning carried out on an upper part of the chassis 5 near its plate 4 and between any two successive wheels 6 carried for said chassis 5.

Selon l'exemple représenté sur les figures 1, 4, 5, 6, 11, 12, l'amincissement local 13 constitue une lame de flexion dans la direction longitudinale du châssis et est obtenu en pratiquant deux saignées 14 sensiblement verticales sur deux ailes latérales 10 du châssis 5 issues de la platine 4 et s'étendant longitudinalement sans discontinuité, la valeur "e" de cet amincissement, compris entre le plan de ladite platine 4 et le sommet des saignées 14 étant déterminée en fonction du moment fléchissant à obtenir.According to the example shown in FIGS. 1, 4, 5, 6, 11, 12, the local thinning 13 constitutes a bending blade in the longitudinal direction of the chassis and is obtained by making two grooves 14 substantially vertical on two lateral wings 10 of the chassis 5 coming from the plate 4 and extending longitudinally without discontinuity, the value "e" of this thinning, lying between the plane of said plate 4 and the apex of the grooves 14 being determined as a function of the bending moment to be obtained.

Selon un autre concept représenté sur les figures 2 et 3, l'amincissement local, respectivement 13A, 13B, est obtenu à partir d'ailes latérales longitudinales 10 issues de la platine, respectivement 4A, 4B, d'un châssis, respectivement 5A, 5B, réalisé en deux parties A, B, distinctes, lesdites ailes 10 étant disposées, côte à côte selon un écartement "e'" dans le sens longitudinal, prédéterminé en fonction de l'angle de flexion maximum souhaité desdites deux parties A, B, l'assemblage de ces deux parties distinctes A, B, du châssis respectivement 5A, 5B, s'effectuant par l'intermédiaire d'un organe de liaison rapporté respectivement 15, 16, et disposé à la partie supérieure dudit châssis à proximité de la platine respectivement 4A, 4B.According to another concept shown in FIGS. 2 and 3, the local thinning, respectively 13A, 13B, is obtained from longitudinal lateral wings 10 coming from the plate, respectively 4A, 4B, from a chassis, respectively 5A, 5B, produced in two separate parts A, B, said wings 10 being arranged, side by side at a distance "e '" in the longitudinal direction, predetermined as a function of the maximum desired bending angle of said two parts A, B , the assembly of these two separate parts A, B, of the chassis respectively 5A, 5B, being effected by means of an attached connecting member respectively 15, 16, and arranged at the upper part of said chassis near the plate respectively 4A, 4B.

Plus particulièrement, selon l'exemple de la figure 2, l'organe de liaison des deux parties distinctes A, B, du châssis 5A est constitué par un axe d'articulation 15 disposé entre deux zones de recouvrement latérales 17, 18, réalisées à la partie supérieure de ses ailes 10.More particularly, according to the example of Figure 2, the connecting member of the two separate parts A, B, of the chassis 5A is constituted by a hinge pin 15 disposed between two lateral overlap zones 17, 18, made at the upper part of its wings 10.

Selon l'exemple de la figure 3, l'organe de liaison des deux parties distinctes du châssis est constitué par une plaquette rapportée formant une lame de flexion 16 reliant longitudinalement deux parties distinctes A, B, de la platine supérieure 4B du châssis 5B.According to the example of Figure 3, the connecting member of the two separate parts of the chassis is constituted by an added plate forming a bending blade 16 longitudinally connecting two separate parts A, B, of the upper plate 4B of the chassis 5B.

Comme le montrent particulièrement bien les figures 8 et 9, la lame de flexion 16 est fixée sur les parties A et B formant le châssis 5B par quatre vis 20 en prise avec des trous filetés correspondants, ménagés sur lesdites parties A et B.As shown particularly in FIGS. 8 and 9, the flexion blade 16 is fixed to the parts A and B forming the frame 5B by four screws 20 engaged with corresponding threaded holes, formed on the said parts A and B.

Bien entendu, quels que soient les cas de figures précités on peut très bien imaginer, pour des patins plus longs par exemple, de réaliser un châssis en trois parties ou plus, plutôt qu'en deux. Dans les deux cas représentés aux figures 2 et 3, aussi bien la lame de flexion 16 que l'articulation 15 constituent la zone déformable en direction longitudinale.Of course, whatever the aforementioned scenarios, one can very well imagine, for longer pads for example, to make a chassis in three or more parts, rather than in two. In the two cases shown in FIGS. 2 and 3, both the flexion blade 16 and the articulation 15 constitute the deformable zone in the longitudinal direction.

Selon un mode de réalisation non représenté, le châssis peut également être réalisé en deux parties distinctes A, B, reliées entre elles par un bloc en élastomère de densité prédéterminée en fonction du moment fléchissant à obtenir, pour constituer la zone déformable 13 en direction longitudinale.According to an embodiment not shown, the chassis can also be made in two separate parts A, B, connected together by an elastomer block of predetermined density according to the bending moment to be obtained, to form the deformable zone 13 in the longitudinal direction .

Les deux parties distinctes A, B, du châssis 5, 5A, 5B, sont réalisées en un matériau de même nature ou bien de nature différente. C'est ainsi qu'une partie A pourra être une matière plastique tandis que la partie B une matière métallique.The two separate parts A, B, of the frame 5, 5A, 5B, are made of a material of the same nature or else of a different nature. Thus a part A can be a plastic material while part B a metallic material.

Selon une autre caractéristique de l'invention, la zone déformable 13, 13A, 13B, du châssis 5 est associée à des moyens de contrôle de sa déformabilité 21 de manière à permettre la modification de son moment fléchissant en cours de patinage et/ou la modification de l'alignement du plan inférieur des roues 6 du patin 1.According to another characteristic of the invention, the deformable zone 13, 13A, 13B, of the chassis 5 is associated with means for controlling its deformability 21 so as to allow the modification of its bending moment during skating and / or the modification of the alignment of the lower plane of the wheels 6 of the shoe 1.

Selon un exemple de réalisation représenté sur les figures 4, 5, 6, 7, 8, adapté aux châssis 5, 5A, 5B, des figures 1 à 3, les moyens de contrôle de la zone déformable située entre au moins deux parties A, B, du châssis 5, 5A, 5B, continues ou discontinues, sont constituées à chaque fois par deux écrous 22 respectivement fixés sur chacune des parties A, B, du châssis 5, 5A, 5B, et reliés entre eux dans un sens longitudinal par une vis de liaison 23 à pas contraires, dont une roue à molette radiale 24 émerge à l'extérieur en direction transversale du châssis 5, 5A, 5B, entre ses deux parties A, B, afin de permettre par son actionnement l'écartement ou au contraire le rapprochement desdites parties A, B, et par conséquent de les actionner en flexion angulaire dans un sens ou dans l'autre selon que le patineur souhaite répartir son appui sur deux roues centrales ou sur toutes les roues 6.According to an exemplary embodiment shown in FIGS. 4, 5, 6, 7, 8, adapted to the chassis 5, 5A, 5B, in FIGS. 1 to 3, the means for controlling the deformable zone situated between at least two parts A, B, of the chassis 5, 5A, 5B, continuous or discontinuous, are constituted each time by two nuts 22 respectively fixed on each of the parts A, B, of the chassis 5, 5A, 5B, and connected together in a longitudinal direction by a connecting screw 23 with opposite pitch, a radial wheel 24 of which emerges outside in the transverse direction of the chassis 5, 5A, 5B, between its two parts A, B, in order to allow by its actuation the spacing or on the contrary, the bringing together of said parts A, B, and consequently of actuating them in angular bending in one direction or the other depending on whether the skater wishes to distribute his support on two central wheels or on all the wheels 6.

Ainsi, il est permis d'ajuster ou de modifier la répartition des roues au sol afin que le patineur puisse soit effectuer des virages courts en répartissant l'appui au sol sur les deux roues centrales, soit effectuer des virages plus longs en répartissant l'appui au sol sur quatre roues, pour une plus grande stabilité en ligne droite ou grande courbe.Thus, it is allowed to adjust or modify the distribution of the wheels on the ground so that the skater can either make short turns by distributing the ground support on the two central wheels, or make longer turns by distributing the ground support on four wheels, for greater stability in a straight line or large curve.

Selon les cas de figures représentés sur les figures 9 à 12, les moyens de contrôle de la zone déformable, située entre au moins deux parties A, B, de châssis 5, 5A, 5B, continues ou discontinues, sont constitués par un verrou 25, 25B en forme de barrette articulée selon un plan vertical par l'une de ses extrémités 25a, 25Ba, en un axe de rotation fixe 26 solidaire de l'une des parties A, B, du châssis 5, 5A, 5B, et susceptible de coopérer de manière amovible par son autre extrémité libre 25b, 25Bb sur au moins un élément d'accrochage 26 ménagé sur l'autre partie du châssis 5, 5A, 5B.According to the cases shown in Figures 9 to 12, the means for controlling the deformable zone, located between at least two parts A, B, of frame 5, 5A, 5B, continuous or discontinuous, are constituted by a lock 25 , 25B in the form of a bar articulated in a vertical plane by one of its ends 25a, 25B a , in a fixed axis of rotation 26 integral with one of the parts A, B, of the chassis 5, 5A, 5B, and capable of cooperating detachably by its other free end 25b, 25B b on at least one hooking element 26 formed on the other part of the chassis 5, 5A, 5B.

Plus particulièrement, selon l'exemple des figures 11, 12, l'extrémité libre 25b du verrou 25 comporte au moins un cran de réglage 27 apte à coopérer avec une butée 26a du châssis de manière à immobiliser les deux parties A, B, du châssis 5, 5A, 5B, dans une position donnée correspondant à un alignement choisi des roues 6 par rapport au sol de façon à autoriser un patinage selon cet alignement choisi, sans flexibilité dudit châssis. Ce verrou 25 peut également rester libre comme représenté sur la figure 11 pour un patinage selon un alignement libre des roues 6 s'auto-adaptant au profil du sol.More particularly, according to the example of FIGS. 11, 12, the free end 25b of the lock 25 comprises at least one adjustment notch 27 able to cooperate with a stop 26a of the chassis so as to immobilize the two parts A, B, of the chassis 5, 5A, 5B, in a given position corresponding to a chosen alignment of the wheels 6 with respect to the ground so as to allow slippage according to this chosen alignment, without flexibility of said chassis. This lock 25 can also remain free as shown in FIG. 11 for slippage according to a free alignment of the wheels 6 self-adjusting to the profile of the ground.

Selon l'exemple des figures 9 et 10, l'extrémité libre 25Bb du verrou 25B comporte un téton 28 apte à coopérer avec au moins un trou de réglage 29 de manière à immobiliser les deux parties du châssis A, B dans une position correspondant à un alignement choisi des roues 6 par rapport au sol, soit dans une position neutre sensiblement alignée en positionnant le téton 28 dans le trou de réglage 29 du milieu, sort dans une position des roues respectivement "rocker" ou "anti-rocker" par placement du téton 28 dans le trou 29 respectivement supérieur ou inférieur.According to the example of FIGS. 9 and 10, the free end 25B b of the lock 25 B comprises a stud 28 able to cooperate with at least one adjustment hole 29 so as to immobilize the two parts of the frame A, B in a position corresponding to a selected alignment of the wheels 6 relative to the ground, either in a neutral position substantially aligned by positioning the stud 28 in the adjustment hole 29 in the middle, comes out in a position of the wheels respectively "rocker" or "anti-rocker" by placing the stud 28 in the hole 29 respectively upper or lower.

Selon une caractéristique supplémentaire de l'invention représentée sur les figures 11, 12, 13 et 14, des moyens d'amortissement 30, élastiquement déformable tant à l'étirement qu'à la compression, sont interposés entre les deux parties A, B, continues ou discontinues du châssis 5, 5A, 5B, dans sa zone de déformation 13, 13A, 13B, et agissent en combinaison avec les moyens de contrôle 22, 23, 24, 25, 25B, 26, 27, 28.According to an additional characteristic of the invention shown in FIGS. 11, 12, 13 and 14, damping means 30, elastically deformable both in stretching and in compression, are interposed between the two parts A, B, continuous or discontinuous of the chassis 5, 5A, 5B, in its deformation zone 13, 13A, 13B, and act in combination with the control means 22, 23, 24, 25, 25B, 26, 27, 28.

Selon une autre caractéristique de l'invention, la zone de déformation 13, 13A, 13B, du châssis 5, 5A, 5B, est disposée sur celui-ci au droit d'une zone de flexion correspondante 31 de la chaussure 2 de manière à assurer une déformabilité de l'ensemble patin/chaussure simultanément, et faciliter la déformation du châssis en permettant une action positive du pied en ce sens.According to another characteristic of the invention, the deformation zone 13, 13A, 13B, of the chassis 5, 5A, 5B, is arranged on the latter in line with a corresponding flexion zone 31 of the shoe 2 so as to ensure deformability of the skate / shoe assembly simultaneously, and facilitate the deformation of the chassis by allowing a positive action of the foot in this direction.

En fait, l'invention qui vient d'être décrite permet d'obtenir un châssis de configuration déformable suivant les contraintes imposées soit par le patineur, soit par le profil du terrain et d'avoir respectivement une fonction guidante et une fonction amortissante comme déjà évoqué.In fact, the invention which has just been described makes it possible to obtain a chassis of deformable configuration according to the constraints imposed either by the skater or by the profile of the terrain and to have respectively a guiding function and a damping function as already mentioned.
