Abstract
Description
La présente invention concerne un patin à roues en ligne. Plus particulièrement, l'invention trouve une application avantageuse dans la pratique d'un patinage dit « agressive ». L'invention n'est toutefois pas limitée à cette discipline particulière du patin à roues en ligne et peut être utilisée sur des patins de hockey, de course ou encore destinés à la pratique récréationnelle (appelée aussi « fitness »).The present invention relates to an inline skate. More in particular, the invention finds an advantageous application in practice of an “aggressive” skating. The invention is however not limited to this particular discipline of inline skating and can be used on roller skates hockey, racing or intended for recreational practice (also called "Fitness").
De manière connue, un patin est constitué par un châssis comportant une partie inférieure longitudinale, généralement formée de parois latérales parallèles, sur laquelle sont disposées les roues ; laquelle partie inférieure est surmontée d'une platine destinée à la fixation de la semelle d'une chaussure.In known manner, a skate is constituted by a chassis comprising a longitudinal bottom part, generally formed by parallel side walls, on which the wheels are arranged; which lower part is surmounted by a plate intended for fixing the sole of a shoe.
L'évolution de la technique dans le domaine des patins à roues en ligne a apporté des solutions en réponse à des besoins issus de la pratique, comme celui d'autoriser un certain nombre de réglages tels que, par exemple, le réglage de la position angulaire du châssis par rapport à l'axe de la chaussure.The evolution of technique in the field of inline skates has provided solutions in response to practical needs, such as that to authorize a certain number of adjustments such as, for example, the adjustment of the angular position of the chassis relative to the axis of the shoe.
Dans la pratique, on constate que le pied du patineur ne doit pas être disposé dans la chaussure sur une surface de semelle plane ; mais au contraire, le talon est préférablement surélevé par rapport au reste du pied ; ce qui a pour effet de favoriser la maniabilité du patin. Pour cela, il est connu de proposer des châssis comprenant une platine de réception formée d'une partie d'avant pied et d'une partie de talon qui sont décalées verticalement ; la partie de talon étant surélevée par rapport à la partie arrière. En règle générale, plus le décalage est important, plus la maniabilité est bonne. Le WO 97/18019 décrit un patin dont le châssis présente un tel décalage et dans lequel un pad recouvrant la semelle permet la compression de la portion talon articulée.In practice, we see that the skater's foot should not be placed in the shoe on a flat sole surface; but on the contrary, the heel is preferably raised relative to the rest of the foot; which has the effect of promoting maneuverability of the skate. For this, it is known to offer chassis comprising a receiving plate formed by a forefoot part and a heel part which are vertically offset; the heel portion being raised relative to the rear part. In general, the larger the shift, the more maneuverability is good. WO 97/18019 describes a shoe whose chassis has such an offset and in which a pad covering the sole allows compression of the heel portion articulated.
Afin de conférer au patineur une grande maniabilité de ses patins, les différences de hauteurs (décalage) peuvent varier entre 11 et 20 mm, voire même 25 mm.In order to give the skater great maneuverability of his skates, the differences in height (offset) can vary between 11 and 20 mm, or even 25 mm.
Or la solution d'un décalage de la platine du châssis présente des inconvénients. En particulier, dans la pratique de « l'agressive », la surface inférieure de la platine sert de surface de glissement sur divers supports comme des rampes, des barres ou des bordures. Une différence de hauteur entre une partie avant et une partie arrière de la platine pose des problèmes dans la recherche de l'équilibre lors du glissement.However the solution of a shift of the plate of the chassis presents disadvantages. In particular, in the practice of "aggressive", the lower surface of the plate serves as a sliding surface on various supports such as ramps, bars or borders. A difference in height between a front part and a rear part of the plate poses problems in the search for balance when sliding.
Un autre inconvénient vient de ce qu'il est nécessaire de prévoir l'utilisation d'un châssis correspondant à un décalage propre par type de chaussure et selon la discipline pratiquée. Il est donc difficile de proposer un châssis standard ; par exemple, pouvant s'adapter à une grande variété de chaussures, ou encore, pouvant être utilisé dans différentes disciplines. Another disadvantage comes from the fact that it is necessary to provide for the use a frame corresponding to a specific offset by type of shoe and according to the discipline practiced. It is therefore difficult to offer a standard chassis; through example, can adapt to a wide variety of shoes, or can be used in different disciplines.
Un autre problème connu dans certaines disciplines, comme la pratique de « l'agressive » ou d'autres, concerne le manque d'amortissement lors des nombreux chocs subis au niveau des talons par les patineurs comme en réception de sauts sur le sol, par exemple. Il est certes connu de disposer d'organes d'amortissement entre le châssis et la coque de la chaussure, mais ceci présente aussi des inconvénients. En particulier, on peut constater une perte d'énergie substantielle dans les efforts transmis par le patineur entre la coque de la chaussure et le châssis supportant les roues, ainsi qu'une perte dans le retour des informations du sol au pied du patineur. La liaison entre la coque et le châssis est aussi plus délicate à réaliser et peut occasionner des problèmes de résistance. On peut aussi constater une moindre maniabilité des patins du fait du positionnement de l'interface d'amortissement entre deux éléments de base du patin.Another problem known in some disciplines, such as the practice of "Aggressive" or others, concerns the lack of amortization during the many heel shocks suffered by skaters as when receiving jumps on the soil, for example. It is certainly known to have damping devices between the chassis and shell of the shoe, but this also has drawbacks. In particular, we can see a substantial loss of energy in efforts transmitted by the skater between the boot shell and the chassis supporting the wheels, as well as a loss in the return of information from the ground to the skater's foot. The connection between the shell and the chassis is also more difficult to achieve and can cause resistance problems. We can also see a lesser maneuverability of the pads due to the positioning of the damping interface between two basic elements of the skate.
L'un des buts de l'invention est donc d'apporter une solution qui permette de répondre aux exigences liées à la différence de hauteur entre l'appui du talon du pied et l'appui au niveau des métatarses pour conserver de la maniabilité au patin, tout en ayant un châssis de conception simplifié et adapté à des types de pratiques spécifiques telles que celle de « l'agressive ». Plus précisément, un châssis adapté à la pratique de « l'agressive » s'entend d'un châssis ayant une surface de glissement appropriée sans décalage de hauteur au niveau de sa platine. Selon le but recherché un tel châssis a aussi pour avantage de se prêter plus aisément à la standardisation et l'interchangeabilité.One of the aims of the invention is therefore to provide a solution which makes it possible to meet the requirements related to the height difference between the heel support of the foot and support at the metatarsal level to maintain maneuverability on the skate, while having a simplified design chassis and adapted to types of practices specific such as that of "aggressive". More specifically, a chassis adapted to the “aggressive” practice means a chassis with a sliding surface suitable without height offset at its plate. Depending on the goal such a chassis also has the advantage of lending itself more easily to standardization and interchangeability.
Un autre but de l'invention est de proposer un patin qui offre à la fois une solution satisfaisante à la surélévation du talon, comme évoqué précédemment, tout en apportant un amortissement approprié aux chocs ; ceci, sans perte excessive de transmission des efforts entre le pied et les roues et en conférant une bonne maniabilité au patin.Another object of the invention is to propose a skate which offers both a satisfactory solution to raising the heel, as mentioned above, all providing adequate shock absorption; this without excessive loss of transmission of forces between the foot and the wheels and giving good maneuverability on the skate.
A cet effet, l'invention concerne un patin à roues en lignes comprenant une chaussure et un châssis ; ledit châssis ayant une partie inférieure longitudinale sur laquelle sont disposées une pluralité de roues munies d'axes de rotation alignés selon un plan de référence ; laquelle partie inférieure est surmontée par une platine destinée à recevoir la semelle de la chaussure, caractérisé en ce que la chaussure comprend un élément de calage interne disposé sur le fond de la chaussure de façon à définir la position angulaire d'une partie au moins du pied par rapport au plan de référence en produisant une différence de hauteur entre le plan d'appui du talon du pied et le plan d'appui plantaire au niveau des métatarses.To this end, the invention relates to an inline skate comprising a shoe and frame; said chassis having a longitudinal lower part on which are arranged a plurality of wheels provided with axes of rotation aligned along a reference plane; which lower part is surmounted by a plate intended to receive the sole of the shoe, characterized in that the shoe includes an internal wedging element arranged on the bottom of the shoe so to define the angular position of at least part of the foot relative to the plane of reference by producing a difference in height between the heel support plane of the foot and the plantar support plan at the metatarsal level.
Selon une caractéristique complémentaire, l'élément de calage interne constitue un élément d'amortissement des chocs comprenant un matériau élastiquement déformable. According to an additional characteristic, the internal wedging element constitutes a shock absorbing element comprising a material elastically deformable.
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. Cette description, donnée à
titre d'exemple non limitatif, se propose de faire mieux comprendre comment
l'invention peut être réalisée, en référence aux dessins annexés sur lesquels :
Le patin à roues en ligne 1 désigné dans son ensemble, est représenté à la
figure 1 et est plus particulièrement destiné à la pratique d'un patinage dit
« agressive » ou « urbain », ou encore à la pratique du hockey.The
Il est constitué par un châssis 5 comportant une partie inférieure longitudinale
sur laquelle sont disposées une pluralité de roues 6, qui est surmontée par une
platine 4 destinée à la fixation d'une chaussure 2 formée par une tige 7, dont sa partie
basse de recouvrement du pied constituée de préférence par une coque en matière
synthétique plus ou moins rigide intègre une semelle externe 3 et se prolonge par
une partie haute 20 en direction de la cheville d'un patineur, et par exemple par un
collier 20 articulé sur des axes 19.It consists of a frame 5 comprising a longitudinal lower part
on which are arranged a plurality of
De manière connue, 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, en l'occurrence des vis 8
traversant la platine 4 pour se visser dans les bords latéraux de la semelle 3. La
fixation disposée latéralement par rapport à une fixation centrale a pour avantage de
pouvoir utiliser des matériaux plus souples pour la partie de chaussure assurant
confort et enveloppement tout en conservant une bonne qualité de transmission avec
le châssis.In known manner, the sole 3 of the
La partie inférieure longitudinale du châssis 5, perpendiculaire à la platine 4,
est constituée par exemple par deux ailes latérales verticales 10, parallèles entre elles,
et disposées de part et d'autre de l'axe longitudinal dudit châssis.The lower longitudinal part of the chassis 5, perpendicular to the
Les ailes latérales 10 se prolongent respectivement à deux parties supérieures ;
l'une avant 4a, l'autre arrière 4b. Les parties avant 4a et arrière 4b de la platine ont
une surface de glissement 11, formant un retour dirigé vers l'extérieur, qui est
alignée selon un plan de glissement P1 sensiblement parallèle aux axes 12 des roues
6. Ainsi, le châssis ne possède pas de décalage de hauteur ; ce qui favorise la pratique
de « l'agressive » lorsque le patineur utilise les parties avant et arrière de la platine
comme surface de glissement. The
Les ailes latérales verticales 10 définissent globalement avec la semelle 3 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 d'axes d'articulation
transversaux 12, solidaires du châssis 4, pour constituer un train roulant. Les axes
d'articulation 12 sont généralement alignés entre eux horizontalement le long d'un
plan O ; lequel est sensiblement parallèle au plan du sol (non représenté).The vertical
Comme le montrent les figures, la platine 4 est horizontale et s'étend
sensiblement parallèlement aux axes d'articulation 12 des roues 6 de façon à fournir
une surface de glissement relativement plane. De préférence la platine 4 peut
également être partiellement intégrée à la semelle 3 de la chaussure, dans des
logements 3a associés de celle-ci, de façon à constituer, avec la surface inférieure de
cette dernière, une surface de glissement la plus large possible.As shown in the figures, the
Selon l'invention, la chaussure 2 comporte un élément de calage interne 21
réalisé en matériau élastiquement déformable et disposé sur le fond 2a, plat, de la
chaussure 2, pour constituer à la fois un moyen d'amortissement des chocs et un
moyen de réglage de la position angulaire α du pied d'un patineur par rapport au
sol, en induisant une différence de hauteur Δh entre le plan d'appui du talon T du
pied et son plan d'appui plantaire P au niveau des métatarses. Un tel élément de
calage 21 peut être bien entendu disposé dessus ou dessous une semelle interne (non
représentée sur le dessin).According to the invention, the
Selon l'exemple de réalisation de la figure 2, l'élément de calage interne 21
présente une partie arrière 21a d'épaisseur Δh sensiblement constante et destinée à
recevoir le talon, cette partie arrière 21a allant en s'amincissant vers l'avant jusqu'au
niveau de la voûte plantaire par une partie 21b sensiblement en forme de coin. Cet
élément de calage présente donc une forme anatomique et est constitué en un
matériau amortissant et élastiquement déformable. De préférence, il est rapporté sur
le fond 2a de la chaussure 2 de manière amovible, de manière à permettre son
interchangeabilité avec des éléments de calage de hauteurs différentes procurant un
Δh différent pouvant notamment varier de 18 à 25 mm. Il peut bien entendu être
également réalisé de manière fixe. L'élément de calage interne a pour effet de
positionner une partie au moins du pied dans une configuration inclinée favorisant la
maniabilité du patin. En particulier la partie de talon est amenée dans une position
angulaire (alpha) par rapport au plan de référence 0 passant par les axes des roues.According to the embodiment of Figure 2, the
Selon une variante de réalisation (non représentée), l'élément de calage interne
21 est une pièce en matériau élastiquement déformable de matière différente de celui
formant la semelle externe 3 de la chaussure 2 et réalisée simultanément à ladite
semelle externe 3 par surmoulage ou bi-injection, au cours d'une même opération. According to an alternative embodiment (not shown), the
Selon un mode de réalisation avantageux, l'élément de calage 21 peut être
constitué par une mousse à cellules fermées, de façon à pouvoir être usiné par
enlèvement de matière et adapté à la hauteur souhaitée par l'utilisateur.According to an advantageous embodiment, the
Dans un autre mode de réalisation représenté à la figure 3, la platine 4 du
châssis est formée d'une seule partie latérale de chaque côté des ailes verticales 10,
formant un retour extérieur, qui s'étend de façon continue de l'avant vers l'arrière du
patin. Dans ce cas, la surface de glissement forme une surface plane continue dans le
plan de glissement P1. Une telle surface est ainsi mieux adaptée à la pratique de
« l'agressive » que sur un châssis traditionnel.In another embodiment shown in FIG. 3, the
Préférentiellement, le matériau élastiquement déformable constituant
l'élément de calage 21 en forme de coin est un polyuréthanne ou un polyéthylène.Preferably, the elastically deformable material constituting
the wedge-
Les essais ont pu démontrer qu'un polyuréthanne de densité 0,38 donnait d'excellents résultats.Tests have been able to demonstrate that a polyurethane with a density of 0.38 gives excellent results.
Néanmoins, il est bien entendu tout à fait possible d'envisager d'autres types de matériaux pourvu qu'ils soient élastiquement déformables de manière à amortir efficacement les chocs dus à la pratique de ces disciplines.However, it is of course quite possible to consider other types of materials provided that they are elastically deformable so as to cushion effectively the shocks due to the practice of these disciplines.
