Description

L'invention concerne une nouvelle chaussure de ski en matière plastique.The invention relates to a new plastic ski boot.

Depuis toujours, les chaussures destinées à la pratique du ski alpin, qu'elles soient en cuir ou en matière plastique, ont visé à enfermer l'articulation de la cheville par l'intermédiaire d'une tige montante. Comme cette tige, pour des raisons de confort, manquait de rigidité dans les plans latéraux, on a proposé d'ajouter des renforts au niveau des malléoles (voir par exemple document FR-A-1 126 589).Historically, boots intended for alpine skiing, whether leather or plastic, have aimed to enclose the ankle joint by means of a rising rod. As this rod, for reasons of comfort, lacked rigidity in the lateral planes, it has been proposed to add reinforcements at the malleoli (see for example document FR-A-1 126 589).

Comme le blocage de l'articulation de la cheville présente des inconvénients pour la flexion longitudinale, on a suggéré de réaliser la chaussure en deux parties, à savoir une tige supérieure dite "collier" et une partie basse dite "coque", ces deux parties étant alors articulées suivant un axe pratiquement perpendiculaire au plan longitudinal (voir document FR-A-1 253 682).As the blocking of the ankle joint has drawbacks for longitudinal flexion, it has been suggested to make the shoe in two parts, namely an upper rod called "collar" and a lower part called "shell", these two parts then being articulated along an axis practically perpendicular to the longitudinal plane (see document FR-A-1 253 682).

C'est la raison pour laquelle toutes les chaussures de ski en matière plastique utilisées jusqu'à ce jour, sont conçues selon cette architecture de base qui vise à condamner la liberté de mouvement latérale du pied sur la cheville, tout en permettant toutefois à la jambe une certaine liberté de flexion longitudinale régulée et contrôlée.This is the reason why all the plastic ski boots used to date are designed according to this basic architecture which aims to condemn the freedom of lateral movement of the foot on the ankle, while nevertheless allowing the leg a certain freedom of longitudinal flexion regulated and controlled.

Or, l'évolution de la technique du ski se traduit par une augmentation des vitesses, le besoin d'une plus grande finesse de perception des sensations pour obtenir une meilleure précision dans la conduite des skis.However, the evolution of the ski technique results in an increase in speeds, the need for greater finesse of perception of sensations to obtain better precision in the handling of skis.

Comme on le sait, une chaussure de ski en matière plastique comprend essentiellement :

  • . une coque destinée à recevoir un chausson qui reçoit à son tour un pied du skieur ;
  • . un collier articulé sur la coque, destiné à enserrer le bas de la jambe, constitué soit en une seule partie, soit en deux parties dénommées alors manchettes, respectivement avant et arrière ;
  • . des moyens de serrage du collier sur le bas de la jambe et du pied dans la coque.
As is known, a plastic ski boot essentially comprises:
  • . a shell intended to receive a liner which in turn receives a foot from the skier;
  • . a collar articulated on the shell, intended to enclose the bottom of the leg, constituted either in a single part, or in two parts then called cuffs, respectively front and rear;
  • . means for tightening the collar on the lower leg and the foot in the shell.

Jusqu'à ce jour, le collier unique ou les deux manchettes sont articulés sur la coque, exclusivement autour d'un axe sensiblement perpendiculaire au plan médian de la coque.To date, the single collar or the two cuffs have been articulated on the shell, exclusively around an axis substantially perpendicular to the median plane of the shell.

L'invention vise une chaussure de ski en matière plastique du type à coque et à collier articulé, dans lequel on respecte tous les degrés de liberté de la jambe, de la cheville et du pied.The invention relates to a ski boot made of plastic material of the shell and articulated collar type, in which all the degrees of freedom of the leg, ankle and foot are respected.

Cette chaussure de ski en matière plastique constituée par :

  • . une coque, destinée à recevoir le pied du skieur, comportant un plan longitudinal médian ;
  • . un étrier rigide en forme de U, articulé sur la coque présentant deux branches ;
  • . un collier, destiné à enserrer le bas de la jambe, articulé sur les deux branches de l'étrier rigide

se caractérise en ce que la portion de raccordement des deux branches de l'étrier en U, est articulée sur l'arrière de la coque autour d'un axe disposé dans le plan longitudinal médian de la coque.This plastic ski boot consisting of:
  • . a shell, intended to receive the skier's foot, comprising a median longitudinal plane;
  • . a rigid U-shaped stirrup, articulated on the hull having two branches;
  • . a collar, intended to grip the lower leg, articulated on the two branches of the rigid stirrup

is characterized in that the connection portion of the two arms of the U-shaped stirrup is articulated on the rear of the hull around an axis disposed in the median longitudinal plane of the hull.

En d'autres termes, l'invention consiste à articuler le collier par rapport à la coque dans deux plans orthogonaux, respectivement l'un pour permettre les débattements du collier vers l'avant dans un plan longitudinal, l'autre les débattements dans le sens latéral dans un plan pratiquement orthogonal au plan longitudinal, et ce grâce à une pièce intercalaire : l'étrier rigide articulé autour de la coque, de préférence au niveau du talon, de sorte que cet étrier rigide est articulé autour de l'arrière de la coque, à l'instar d'une rotule.In other words, the invention consists in hinging the collar relative to the shell in two orthogonal planes, respectively one to allow the movements of the collar forward in a longitudinal plane, the other the movements in the lateral direction in a plane practically orthogonal to the longitudinal plane, and this thanks to an intermediate piece: the rigid stirrup articulated around the shell, preferably at the heel, so that this rigid stirrup is articulated around the rear of the shell, like a ball joint.

Ainsi, la chaussure permet au skieur d'utiliser dans son intégralité tous les débattements de la jambe sur la cheville et sur le pied, aussi bien dans le plan longitudinal que dans le plan latéral et tous les plans dérivés, ce que l'on ne savait pas obtenir dans des chaussures de ski actuelles en matière plastique.Thus, the boot allows the skier to use in its entirety all the deflections of the leg on the ankle and on the foot, as well in the longitudinal plane as in the lateral plane and all the derived planes, which one does not didn't know how to get in current plastic ski boots.

Avantageusement, en pratique :

  • l'axe d'articulation de l'étrier sur la coque est disposé au voisinage du haut du calcanéum dans un plan parallèle au plan de la base de la semelle et passant par les malléoles ;
  • les deux branches de l'étrier épousent en la coiffant la forme externe des renflements de la coque au niveau des malléoles, et le collier est articulé sur les deux branches de l'étrier rigide sur un axe disposé dans un plan perpendiculaire au plan longitudinal de la coque et disposé au niveau des malléoles ;
  • la face interne de l'extrémité libre des branches latérales de l'étrier en forme de U présente une forme arrondie convexe destinée à épouser la forme externe concave des renflements des malléoles sur la coque ;
  • le débattement de l'étrier sur la coque est limité par des tétons venus de moulage, disposés sur les flancs de la coque, traversant une lumière prévue à cet effet, ménagée dans les branches de l'étrier ;
  • les flancs latéraux de la coque, et de préférence la partie inférieure présentent des éléments visco-élastiques, réglables en hauteur, destinés à limiter et à amortir les débattements de l'étrier ;
  • les parties en regard respectivement de l'étrier et de la coque, et de l'étrier et du collier, sont recouvertes d'un matériau à faible coefficient de frottements: polytétrafluoréthylène par exemple ;
  • l'axe d'articulation de l'étrier rigide sur la coque est situé dans un plan longitudinal et dans un plan parallèle à la base de la semelle de la coque passant entre les deux malléoles, respectivement interne et externe, et de préférence à égale distance de ces deux malléoles ;
  • l'axe d'articulation de l'étrier en U est réglable en position sur l'arrière de la coque.
Advantageously, in practice:
  • the axis of articulation of the stirrup on the shell is arranged in the vicinity of the top of the calcaneus in a plane parallel to the plane of the base of the sole and passing through the malleoli;
  • the two branches of the stirrup conform to the external shape of the bulges of the shell at the level of the malleoli, and the collar is articulated on the two branches of the rigid stirrup on an axis arranged in a plane perpendicular to the longitudinal plane of the shell and disposed at the level of the malleoli;
  • the internal face of the free end of the lateral branches of the U-shaped stirrup has a convex rounded shape intended to match the concave external shape of the bulges of the malleoli on the shell;
  • the movement of the stirrup on the hull is limited by studs coming from molding, arranged on the sides of the hull, passing through a light provided for this purpose, formed in the branches of the stirrup;
  • the lateral sides of the shell, and preferably the lower part have visco-elastic elements, adjustable in height, intended to limit and dampen the movements of the stirrup;
  • the opposite parts respectively of the stirrup and the shell, and of the stirrup and of the collar, are covered with a material with a low coefficient of friction: polytetrafluoroethylene for example;
  • the axis of articulation of the rigid stirrup on the shell is located in a longitudinal plane and in a plane parallel to the base of the sole of the shell passing between the two malleoli, respectively internal and external, and preferably equal distance from these two malleoli;
  • the hinge pin of the U-shaped bracket is adjustable in position on the rear of the hull.

La manière dont l'invention peut être réalisée et les avantages qui en découlent ressortiront mieux des exemples de réalisation qui suivent, à l'appui des figures annexées.The manner in which the invention can be implemented and the advantages which ensue therefrom will emerge more clearly from the following exemplary embodiments, in support of the appended figures.

La figure 1 illustre, vue de côté, une première forme de réalisation de l'invention d'une chaussure à collier unique.Figure 1 illustrates, side view, a first embodiment of the invention of a shoe with a single collar.

La figure 2 montre également vue de côté une autre forme de réalisation de l'invention adaptée aux chaussures à entrée arrière (manchettes avant et arrière).FIG. 2 also shows a side view of another embodiment of the invention suitable for shoes with rear entry (front and rear cuffs).

La figure 3 montre en coupe longitudinale l'arrière de la chaussure côté talon, alors que la figure 4 est une vue de derrière de cette chaussure.Figure 3 shows in longitudinal section the rear of the shoe on the heel side, while Figure 4 is a rear view of this shoe.

La figure 5 montre une forme de réalisation perfectionnée de cet arrière de la chaussure, alors que la figure 6 montre une coupe A-A de cette réalisation.Figure 5 shows an improved embodiment of this rear of the shoe, while Figure 6 shows a section A-A of this embodiment.

En se référant aux figures 1 et 2, la chaussure de ski comprend une coque (1) en matière plastique d'usage et de dureté courants pour cette application. Cette coque (1) comprend une semelle (2) et un talon (3) avec un arrière (4). La chaussure comprend également un collier unique (5) (figure 1) ou deux manchettes, respectivement avant (6) et arrière (7) (figure 2). Les références (8) et (9) désignent des organes de serrage connus (8) du pied dans la coque et (9) du collier sur le bas de la jambe, tel que des boucles, des crémaillères, etc..Referring to Figures 1 and 2, the ski boot comprises a shell (1) of plastic material of common use and hardness for this application. This shell (1) comprises a sole (2) and a heel (3) with a rear (4). The shoe also includes a single collar (5) (Figure 1) or two cuffs, respectively front (6) and rear (7) (Figure 2). References (8) and (9) designate known clamping members (8) of the foot in the shell and (9) of the collar on the lower leg, such as loops, racks, etc.

Selon une première caractéristique de l'invention, la chaussure comporte un étrier rigide en forme de U, désigné par la référence générale (10), par exemple en matière plastique moulée, éventuellement renforcée, ou en métal. Cet étrier rigide comprend deux branches latérales, respectivement (11) et 12), reliées entre elles par une portion de raccordement (13). La portion de raccordement (13) des deux branches latérales (11,12) est articulée en (15) sur l'arrière (4) de la coque (1) au niveau du talon, et plus précisément au niveau ou au voisinage du haut du calcanéum. Cet axe (15) est disposé dans un plan longitudinal de la coque. Les deux branches (11,12) (voir figure 4) de l'étrier (10) épousent, en les coiffant, la forme externe (16,17) des renflements de la coque (1) au niveau des malléoles figurées en pointillés et référencées (18) sur la figure 3. On comprend aisément que cet étrier rigide (10) se comporte vis-à-vis de la coque (1), et plus précisément de l'arrière de la coque (4), à l'instar d'un élément de cardan, ce qui lui permet de s'articuler autour de la coque et plus précisément autour d'un axe disposé à l'intérieur d'un plan longitudinal et d'un plan parallèle au plan de la semelle (3), dans le sens indiqué par la flèche F1.According to a first characteristic of the invention, the shoe comprises a rigid U-shaped stirrup, designated by the general reference (10), for example in molded plastic material, possibly reinforced, or in metal. This rigid bracket includes two lateral branches, respectively (11) and 12), interconnected by a connection portion (13). The connection portion (13) of the two lateral branches (11,12) is articulated at (15) on the rear (4) of the shell (1) at the heel, and more precisely at or near the top calcaneus. This axis (15) is arranged in a longitudinal plane of the hull. The two branches (11,12) (see FIG. 4) of the stirrup (10) follow, by styling them, the external shape (16,17) of the bulges of the shell (1) at the level of the malleoli shown in dotted lines referenced (18) in Figure 3. It is easily understood that this rigid bracket (10) behaves vis-à-vis the hull (1), and more precisely from the rear of the hull (4), to the like a gimbal element, which allows it to be articulated around the shell and more precisely around an axis arranged inside a longitudinal plane and a plane parallel to the plane of the sole ( 3), in the direction indicated by the arrow F1.

L'axe d'articulation (15) de l'étrier rigide (10) sur la coque (1) est comme déjà dit situé dans le plan longitudinal médian et dans un plan horizontal par rapport au plan de la semelle (3) de la coque (1), passant entre les deux malléoles (18) respectivement interne et externe, et à égale distance de ces deux malléoles.The articulation axis (15) of the rigid stirrup (10) on the shell (1) is, as already said, situated in the median longitudinal plane and in a horizontal plane relative to the plane of the sole (3) of the shell (1), passing between the two malleoli (18) respectively internal and external, and at equal distance from these two malleoli.

Selon une autre caractéristique de l'invention, le collier unique (5) (figure 1) ou les deux manchettes (6,7) (figure 2), sont articulés au niveau des malléoles (18) sur les deux branches (11,12) de l'étrier (10) sur des axes ou plus précisément sur des ergots venus de moulage à cet effet (20,21). L'axe d'articulation défini par les deux points d'articulation (20,21) est sensiblement perpendiculaire au plan médian (P) de l'étrier (figure 4). En pratique, la face interne de l'extrémité libre de ces branches latérales (11,12), présente une forme arrondie convexe, destinée à épouser la forme externe concave des renflements des malléoles (18) sur la coque (1). De même, les faces respectives en regard de l'étrier (10) de la coque (1) et de l'étrier (10) et du collier (5,6 ou 7), sont recouvertes d'un matériau à faible coefficient de frottement, notamment de polytétrafluoréthylène.According to another characteristic of the invention, the single collar (5) (Figure 1) or the two cuffs (6,7) (Figure 2), are articulated at the malleoli (18) on the two branches (11,12 ) of the stirrup (10) on axes or more precisely on lugs coming from molding for this purpose (20,21). The axis of articulation defined by the two points of articulation (20,21) is substantially perpendicular to the median plane (P) of the stirrup (FIG. 4). In practice, the internal face of the free end of these lateral branches (11, 12) has a convex rounded shape, intended to match the concave external shape of the bulges of the malleoli (18) on the shell (1). Similarly, the respective faces facing the stirrup (10) of the shell (1) and the stirrup (10) and the collar (5,6 or 7), are covered with a material with a low coefficient of friction, in particular of polytetrafluoroethylene.

De la sorte, comme celà est déjà connu, le collier (5 ; 6,7) est articulé dans le sens indiqué par la flèche F2, autour d'un axe perpendiculaire au plan longitudinal.In this way, as is already known, the collar (5; 6,7) is articulated in the direction indicated by the arrow F2, around an axis perpendicular to the longitudinal plane.

Le débattement de l'étrier (10) sur la coque (1) est limité (voir figures 5 et 6) par des tétons ou des ergots (30), venus de moulage, disposés sur les flancs de la coque (1), traversant une lumière (31) prévue à cet effet, ménagée dans les branches (11,12) de l'étrier (10).The movement of the stirrup (10) on the hull (1) is limited (see Figures 5 and 6) by pins or lugs (30), coming from molding, arranged on the sides of the hull (1), passing through a light (31) provided for this purpose, formed in the branches (11,12) of the stirrup (10).

Les axes caractéristiques (15,20,21) peuvent être réalisés de toute manière connue : rivets, tétons, ergots, etc. .The characteristic axes (15, 20, 21) can be produced in any known manner: rivets, pins, pins, etc. .

Dans une version perfectionnée non représentée, le bas des flancs latéraux de la coque (1) présente des éléments visco-élastiques, réglables en hauteur, destinés à limiter et amortir les débattements des branches (11,12) de l'étrier vers le bas, donc du collier.In an improved version not shown, the bottom of the lateral flanks of the shell (1) has viscoelastic elements, adjustable in height, intended to limit and dampen the deflections of the legs (11,12) of the stirrup downwards. , so the necklace.

Dans une autre forme d'exécution non représentée, la chaussure comporte des moyens permettant de bloquer provisoirement les débattements de l'étrier (10) autour de son axe d'articulation (15) et ce, par exemple pour la pratique du slalom.In another embodiment, not shown, the shoe includes means making it possible to temporarily block the movements of the stirrup (10) around its axis of articulation (15), this, for example for the practice of slalom.

On comprend aisément que grâce à cet étrier caractéristique (10) articulé (F1) autour de la coque (1) sur un axe (15) dispose dans un plan longitudinal, sur lequel est à son tour articulé (F2) le collier (5 ; 6,7), que cet ensemble permet au collier d'avoir des degrés de liberté dans tous les plans et toutes les inclinaisons, à l'instar du pied et de la jambe qui peuvent se déplacer librement autour de la cheville.It is easily understood that thanks to this characteristic stirrup (10) articulated (F1) around the shell (1) on an axis (15) has in a longitudinal plane, on which is in turn articulated (F2) the collar (5; 6,7), that this set allows the collar to have degrees of freedom in all planes and all inclinations, like the foot and the leg which can move freely around the ankle.

La chaussure de ski conforme à l'invention présente de nombreux avantages. On peut citer :

  • une meilleure mise à plat des skis sur la neige en traces directes ;
  • la possibilité de déplacements amortis dans toutes les directions autorisées par la cheville, ce qui améliore le confort, notamment en éliminant les chocs lors des appuis latéraux ;
  • une meilleure reprise des carres, car celle-ci s'effectue désormais au niveau de la cheville et non plus du genou, en mettant en oeuvre par là même des bras de leviers plus courts, donc plus précis, ce qui autorise des gestes plus rapides.
The ski boot according to the invention has many advantages. We can cite :
  • better flattening of skis on snow in direct tracks;
  • the possibility of cushioned movements in all directions authorized by the ankle, which improves comfort, in particular by eliminating shocks during lateral support;
  • a better recovery of the edges, because this is now carried out at the ankle and no longer at the knee, thereby implementing shorter lever arms, therefore more precise, which allows faster gestures .
