Description

L'invention concerne un perfectionnement aux chaussures de ski de fond.The invention relates to an improvement to ski boots background.

Comme on le sait, il existe essentiellement deux techniques pour la pratique du ski de fond, liées chacune à la technique d'avancée.As we know, there are basically two techniques for cross-country skiing, each linked to the advanced technique.

Dans la première technique traditionnelle dite du "pas alternatif", chaque ski est lancé alternativement en avant dans deux rails parallèles ménagés à cet effet dans la piste. Pour la pratique de cette technique, on utilise le plus généralement des chaussures basses dont la semelle est souple et dont éventuellement la tige solidaire de la semelle présente un contrefort externe. Il est indispensable que la semelle soit souple et soit articulée à la pointe de la chaussure sur la face supérieure du patin du ski, pour autoriser le débattement maximum de la chaussure par rapport au ski pour obtenir une poussée et une amplitude de foulée maximums. Il importe également que la semelle soit souple pour accentuer cette poussée.In the first traditional technique known as "alternative step", each ski is launched alternately forward in two parallel rails provided for this purpose in the track. For the practice of this technique, we most generally use low shoes with the sole flexible and possibly with an upper attached to the sole external buttress. It is essential that the sole is flexible and is articulated at the tip of the boot on the upper face of the ski skate, to allow the maximum travel of the shoe relative to the ski for maximum thrust and stride amplitude. he it is also important that the sole is flexible to accentuate this thrust.

Dans la seconde technique, plus récente et plus sportive dite du pas "du patineur", ou plus communément dénommée "skating", le skieur évolue en faisant diverger ses skis. Cette technique est décomposée en quatre phases successives, respectivement une première phase où le ski est en appui externe, suivie d'une phase de glisse à plat, suivie à son tour par une phase d'impulsion ou de poussée sur la face interne du ski, et enfin une phase dite de vol pendant laquelle le ski quitte la neige jusqu'à retrouver un appui externe (première phase) du mouvement suivant. Pour pratiquer cette technique plus efficace et plus rapide, on utilise des chaussures dont la semelle, toujours articulée sur l'avant, est rigidifiée par un cambrion. Par ailleurs, la tige toujours solidarisée à la semelle comporte un collier semi-rigide épousant le bas du tibia, articulé sur un contrefort rigide disposé au niveau des malléoles pour permettre un transfert des impulsions et de la poussée vers le ski. Malheureusement, comme l'articulation de la semelle rigide s'effectue à l'avant de la chaussure, comme précédemment, cette articulation autorise un grand débattement de la semelle par rapport au ski, ce qui perturbe parfois les mouvements du skieur, notamment dans la phase dite "de vol"du ski.In the second technique, more recent and more sporting called the step "skater", or more commonly called "skating", the skier evolves by making his skis diverge. This technique is broken down into four successive phases, respectively a first phase where skiing is in external support, followed by a flat gliding phase, followed in turn by an impulse or push phase on the internal face of the ski, and finally a so-called flight phase during which the ski leaves the snow until regain external support (first phase) of the next movement. To practice this more efficient and faster technique, we use shoes whose sole, always articulated on the front, is stiffened by a shank. In addition, the upper still attached to the sole has a semi-rigid collar hugging the bottom of the tibia, articulated on a rigid buttress placed at the malleoli to allow a transfer of impulses and push towards the ski. Sadly, as the articulation of the rigid sole takes place at the front of the shoe, as before, this articulation allows a large travel of the sole with respect to the ski, which sometimes disturbs movements of the skier, especially in the so-called "flight" phase of skiing.

De la sorte, à ce jour, selon la technique de ski de fond que l'on désire pratiquer, on doit, selon le cas, faire appel soit à des chaussures basses (pas alternatif), soit à des chaussures montantes semi-rigides (pas de patineur). Mais dans tous les cas, actuellement, l'articulation de l'avant de la semelle sur le patin du ski s'effectue autour d'un axe transversal par rapport à l'axe longitudinal de la semelle, lequel coïncide avec l'axe d'équilibre du ski, axe dénommé aussi parfois axe de rotation, disposé selon les normes, soit juste à l'extrémité des orteils, soit juste en retrait et au dessous des orteils pour profiter plus efficacement des mouvements, des impulsions et assurer un meilleur guidage du ski.In this way, to date, according to the cross-country skiing technique that we wish to practice, one must, as the case may be, use either shoes low (not alternative), or to semi-rigid high shoes (not skater). But in all cases, currently, the articulation of the front of the sole on the ski skate is made around an axis transverse to the longitudinal axis of the sole, which coincides with the balance axis of the ski, an axis also sometimes called the axis of rotation, arranged according to standards, either just at the end of the toes, or just in withdrawal and below the toes to benefit more effectively from movements, impulses and ensuring better guidance of the ski.

Dans le document EP-A-0 373 336, on a décrit une chaussure de sport, notamment pour la pratique de l'athlétisme, de la montagne ou du golf, dont la semelle est formée selon la préambule de la revendication 1. In document EP-A-0 373 336, a sports shoe has been described, especially for the practice of athletics, mountain or golf, the sole of which is formed according to the preamble of claim 1.

Dans une forme de réalisation particulière illustrée à la figure 7, l'insert rigide, qui occupe sensiblement toute la surface de la semelle, est formé de deux parties distinctes accolées, respectivement une partie avant, allant de la pointe à la voute plantaire, dans laquelle les ondulations sont dirigées transversalement pour donner de la souplesse lors de la marche, et une partie arrière, allant de la voute plantaire au talon, dans laquelle des ondulations sont inclinées (voute plantaire), puis perpendiculairement (talon) aux précédentes, pour donner de la rigidité. Dans cette réalisation, la ligne de jonction entre les deux parties provoque une discontinuité dans la transmission des efforts, ce qui la rend inapte à la pratique du skating qui exige une succession progressive des appuis depuis le talon vers la pointe.In a particular embodiment illustrated in FIG. 7, the rigid insert, which occupies substantially the entire surface of the sole, is formed of two separate parts joined together, respectively a part before, going from the tip to the arch of the foot, in which the corrugations are directed transversely to give flexibility when walking, and a rear part, going from the arch to the heel, in which undulations are inclined (arch), then perpendicular (heel) to the previous ones, to give rigidity. In this embodiment, the junction line between the two parts causes a discontinuity in the transmission of forces, which makes it incapable of the practice of skating which requires a progressive succession of supports from the heel to the toe.

Dans le document EP-A-0 471 447, on a décrit une chaussure de sport, notamment pour la pratique du tennis, dans laquelle la semelle présente un croisillon moulé dans la semelle, disposé au niveau de la voute plantaire, et en arrière des métatarses, pour compenser et limiter les déformations lors des torsions de la semelle autour de l'axe longitudinal. Ces chaussures ne peuvent pas convenir pour la pratique du skating qui nécessite des appuis fermés sur la zone des métatarses et plus précisément des orteils, plus précisément en fin de la troisième phase d'impulsion ou de poussée.In document EP-A-0 471 447, a sports shoe has been described, especially for the practice of tennis, in which the sole has a cross molded in the sole, placed at the level of the arch plantar, and behind the metatarsals, to compensate for and limit deformations during torsion of the sole around the longitudinal axis. These shoes are not suitable for the practice of skating which requires closed supports on the metatarsal area and more specifically toes, specifically at the end of the third impulse phase or thrust.

L'invention pallie ces inconvénients. Elle vise une chaussure de ski de fond adaptée à la pratique du pas de patineur (skating) qui autorise tout d'abord un centre de poussée idéal pour la pratique de ce pas, à savoir au niveau des orteils, puis un meilleur soutien du pied pendant les quatre phases décrites ci-dessus, et enfin une meilleure conduite à plat du ski et par voie de conséquence, une meilleure glisse. The invention overcomes these drawbacks. She's aiming for a ski boot adapted to the practice of the skating step which allows first of all an ideal center of thrust for the practice of this step, namely at the toes, then better support of the foot during four phases described above, and finally better flat handling of the skiing and as a result, better gliding.

Cette chaussure constituée d'une tige solidaire d'un ensemble formant semelle, qui comprend trois parties principales, respectivement une pointe et un talon, reliés entre eux par une zone intermédiaire correspondant à la voûte plantaire, et qui présente deux faces respectivement externe et interne, disposées de part et d'autre de l'axe longitudinal de la chaussure, et dans laquelle l'ensemble-semelle comporte un élément de renfort continu qui s'étend depuis la face externe de la partie arrière du talon jusqu'à la face interne de la partie avant de la pointe, caracterisée en ce que l'élément de renfort, qui constitue également élement de rigidification, remonte sur le bord de la tige sensiblement à la verticale, respectivement: sur la face externe du talon, au niveau des malléoles et au-dessus de celles-ci; sur la face interne de la pointe, jusqu'à une hauteur correspondante pour la partie à l'épaisseur des orteils.This shoe consisting of a rod secured to a set forming a sole, which comprises three main parts, respectively a toe and a heel, linked together by an intermediate zone corresponding to the arch of the foot, and which has two faces respectively external and internal, arranged on either side of the axis longitudinal of the shoe, and in which the sole assembly comprises a continuous reinforcement element which extends from the external face of the rear part of the heel to the internal face of the front part of the tip, characterized in that the reinforcing element, which also constitutes stiffening, goes up on the edge of the rod substantially vertically, respectively: on the external face of the heel, at the level of the malleoli and above them; on the face internal tip, to a height corresponding to the part to the thickness of the toes.

Dans la description et dans les revendications, par "ensemble-semelle" ou "ensemble formant semelle", on désigne l'ensemble qui coopère avec la tige pour former la chaussure et qui comprend notamment, la semelle proprement dite, mais aussi la première de montage, la première de propreté et le contrefort.In the description and in the claims, by "sole assembly" or "sole assembly" means the assembly which cooperates with the upper to form the shoe and which comprises in particular, the sole itself, but also the first of fitting, the first of cleanliness and the buttress.

Dans une première forme de réalisation avantageuse :

  • l'élément de renfort et de rigidification traverse la semelle en diagonale dans la zone intermédiaire allant des métatarses au talon et est soit rapporté dans la semelle, soit surmoulé, soit de préférence injecté en même temps que la semelle pour former partie intégrante de celle-ci ;

  • dans une forme d'exécution avantageuse, le renfort de la face interne de la pointe se prolonge ensuite pour recouvrir entièrement le dessus des orteils sur l'avant de la pointe, pour ainsi permettre aux orteils d'avoir une contribution active lors de la phase de vol ;
  • dans une autre forme d'exécution, la tige comporte de manière connue un collier qui enserre le bas de la jambe, selon l'invention ce collier étant articulé sur le renfort disposé sur la face externe du talon au niveau des malléoles ;
  • dans une autre forme d'exécution, l'élément de renfort caractéristique n'est pas disposé sur le dessus de la semelle proprement dite, mais à l'intérieur de la tige soit sur la face interne supérieure de la semelle de montage, soit est monté sur la "première" de propreté, qui comme on le sait, fait partie intégrante de l'ensemble-semelle et est le complément indispensable de la semelle proprement dite ; dans cette forme de réalisation, la portion diagonale intermédiaire caractéristique est cambrée pour mieux épouser la forme de la voute plantaire.

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 realized and the advantages which result from this, the following examples of embodiment will emerge more clearly in support of the appended figures.

La figure 1 montre vue de dessous une semelle de chaussure de ski de fond conforme à l'invention (pied gauche).Figure 1 shows a bottom view of a ski boot sole bottom according to the invention (left foot).

Les figures 2, 3 et 4 montrent sommairement d'autres formes d'exécution de l'invention.Figures 2, 3 and 4 briefly show other shapes of the invention.

Les figures 6 et 7 montrent une chaussure vue respectivement côté extérieur pied droit (figure 6) et côté intérieur pied gauche (figure 7).Figures 6 and 7 show a shoe viewed respectively side outside right foot (figure 6) and inside left foot (figure 7).

La figure 8 est une vue de dessus sommaire de la pointe d'une chaussure perfectionnée selon l'invention montrée à la figure 7.Figure 8 is a summary top view of the tip of a improved shoe according to the invention shown in Figure 7.

La figure 9 est une représentation schématique en perspective sommaire d'un élément de renfort selon l'invention formant également contrefort.Figure 9 is a schematic perspective representation summary of a reinforcing element according to the invention also forming buttress.

Comme on le sait (voir figures 6 et 7), une chaussure de ski de fond comprend essentiellement une semelle (1) et une tige (2) solidaire de la semelle, et pour la pratique du skating ou du pas de patineur, d'un collier (3) rigide, articulé par rapport à la tige (2) autour d'un axe (4) disposé au niveau des malléoles. La chaussure comprend également une pointe (5) et un talon (6).As we know (see Figures 6 and 7), a cross-country ski boot essentially comprises a sole (1) and a rod (2) integral with the sole, and for skating or skating, a collar (3) rigid, articulated with respect to the rod (2) around an axis (4) disposed at level of the malleoli. The shoe also includes a toe (5) and a heel (6).

Vue de dessous, la semelle se compose (figure 1), essentiellement de trois zones contigues, respectivement depuis la pointe (5) jusqu'au talon (6), d'une pointe proprement dite (A) correspondant à l'avant du pied, d'un talon (B), ces deux parties principales (A) et (B) étant reliées entre elles par une zone intermédiaire (C) correspondant sensiblement à la zone de la voute plantaire, c'est-à-dire allant des métatarses au talon. Viewed from below, the sole consists (Figure 1), mainly of three contiguous zones, respectively from the toe (5) to the heel (6), with a point proper (A) corresponding to the front of the foot, a heel (B), these two main parts (A) and (B) being connected between them by an intermediate zone (C) corresponding substantially to the arch area, i.e. from the metatarsals to the heel.

L'axe longitudinal (I-I') de la semelle (1) correspond à celui de la chaussure et coïncide avec l'axe longitudinal du ski. De manière connue, la semelle (1) présente vers la pointe (5) un axe (7) d'articulation et de rotation sur la fixation du ski pour permettre le débattement de la chaussure par rapport au patin du ski.The longitudinal axis (I-I ') of the sole (1) corresponds to that of the shoe and coincides with the longitudinal axis of the ski. In a known way, the sole (1) has towards the tip (5) an axis (7) of articulation and rotation on the ski binding to allow the movement of the shoe in relation to the ski skate.

De manière connue, la semelle (1) présente également une ou deux rainures (8,9) parallèles de guidage qui coopèrent avec des nervures complémentaires ménagées à cet effet sur le patin du ski.In known manner, the sole (1) also has one or two parallel guide grooves (8,9) which cooperate with ribs complementary for this purpose on the ski skate.

Selon l'invention, la semelle (1) comporte également un élément de renfort et de rigidification désigné par la référence générale (10), s'étendant depuis l'extrémité de la face externe de la partie arrière (11) du talon (B), puis en diagonale et de manière continue (12) dans la zone médiane (C), et enfin jusqu'à l'extrémité de la face interne (13) de la partie avant de la pointe (A).According to the invention, the sole (1) also comprises an element of reinforcement and stiffening designated by the general reference (10), extending from the end of the external face of the rear part (11) of the heel (B), then diagonally and continuously (12) in the area median (C), and finally to the end of the internal face (13) of the front part of the point (A).

Dans une première forme d'exécution, cet élément de renfort caractéristique (10) est obtenu par double moulage lors de la fabrication de la semelle. Le plus généralement, il importe alors que la matière plastique constituant cet élément de renfort (10) soit plus rigide, du moins dans les conditions d'utilisation, que la matière formant la semelle (1). Cependant, si l'on désire privilégier plus le confort que la technique, il peut être utile dans certaines formes de réalisation, que l'élément (10) soit légèrement plus souple que le reste de la semelle (1).In a first embodiment, this reinforcing element characteristic (10) is obtained by double molding during the manufacture of the sole. Most generally, it is therefore important that the plastic material constituting this reinforcing element (10) is more rigid, at least in the conditions of use, as the material forming the sole (1). However, if you want to focus more on comfort than technique, it can be useful in certain embodiments, that the element (10) is slightly softer than the rest of the sole (1).

Dans une autre forme d'exécution, cet élément de renfort (10) peut être en métal, voire en un matériau composite compatible avec le reste de la semelle. Dans cette forme d'exécution, avantageusement, les fibres de renfort du matériau composite fibreux, sont dirigées dans le sens de la poussée (troisième phase du mouvement). In another embodiment, this reinforcing element (10) can be made of metal or even a composite material compatible with the rest of the sole. In this embodiment, advantageously, the fibers of reinforcement of the fibrous composite material, are directed in the direction of the thrust (third phase of movement).

Contrairement aux réalisations rappelées dans le préambule, les parties caractéristiques avant (13,17) et arrière (11,15), n'occupent pas toutes les zones pointe ou talon au niveau de la semelle, mais seulement une portion latérale minoritaire de cette semelle, et sont dirigées de préférence parallèlement à l'axe longitudinal (I-I').Unlike the achievements mentioned in the preamble, the front (13,17) and rear (11,15) characteristic parts, do not occupy all areas of the toe or heel at the level of the sole, but only a minority lateral portion of this sole, and are directed from preferably parallel to the longitudinal axis (I-I ').

Dans une forme de réalisation pratique, l'élément caractéristique (10) peut épouser des formes variées montrées aux figures 2 à 4, par exemple convergente (figure 2), divergente (figure 3), voire sinusoidale (figure 4).In a practical embodiment, the characteristic element (10) can take various forms shown in Figures 2 to 4, for example convergent (figure 2), divergent (figure 3), even sinusoidal (figure 4).

Dans une variante avantageuse montrée à la figure 5, l'élément de renfort caractéristique (10) remonte à la verticale en (15) sur la tige (1) au niveau du talon côté extérieur et à l'avant en (17) au niveau de la pointe côté intérieur. De préférence, les parties (15 et 17) présentent une surépaisseur par rapport au reste (12) du renfort.In an advantageous variant shown in FIG. 5, the element of characteristic reinforcement (10) rises vertically at (15) on the rod (1) at heel level outside and at the front at (17) at the toe interior side. Preferably, the parts (15 and 17) have a extra thickness compared to the rest (12) of the reinforcement.

Dans une variante montrée aux figures 6 à 8, la face externe (15) se prolonge en (16) au niveau des malléoles pour servir de support à l'axe d'articulation (4) du collier (3) rigide. De même, la face interne (13) de la pointe (A) (voir figures 5,7) remonte jusqu'à une hauteur (17) correspondant en partie à l'épaisseur des orteils, puis peut se prolonger (voir figure 8) sur le dessus et l'avant (18) de la chaussure pour recouvrir le dessus des orteils à l'avant de la pointe (5) (voir figure 8), pour augmenter la contribution active des orteils lors de la phase de vol. In a variant shown in Figures 6 to 8, the outer face (15) is extends at (16) at the malleoli to support the axis articulation (4) of the rigid collar (3). Similarly, the internal face (13) of the point (A) (see figures 5,7) goes up to a height (17) partly corresponding to the thickness of the toes, then may extend (see Figure 8) on the top and front (18) of the shoe to cover the top of the toes in front of the tip (5) (see Figure 8), to increase the active contribution of the toes during the flight phase.

Lors de la pratique du ski selon le pas de patineur, le skieur prend tout d'abord appui sur le ski et par là sur le sol pour exercer sa poussée, tout d'abord sur la face externe (11) du talon et par là sur l'élément de renfort correspondant, continue la poussée en basculant le pied, donc la chaussure, autour de l'axe I-I' jusqu'à finir l'appui et la poussée sur la portion avant interne (13).When skiing according to the skater's step, the skier takes first of all press on the ski and thereby on the ground to exert its push, first of all on the external face (11) of the heel and thereby on the element of corresponding reinforcement, continues the push by tilting the foot, so the shoe, around the axis I-I 'until the support and the thrust on the internal front portion (13).

On obtient ainsi une poussée idéale, favorable à la pratique du pas de patineur.We thus obtain an ideal thrust, favorable to the practice of the step skater.

Dans la forme de réalisation pratique illustrée à la figure 9, l'élément caractéristique de renfort désigné par la référence (20) forme également contrefort. Cet élément (20) monopièce réalisé en matière plastique par moulage, comprend une base (21) destinée à venir s'insérer, notamment par collage, sous la première de montage. Cette base (21) présente des ouvertures (22) destinées à recevoir un insert de rigidification disposé au niveau de la voute plantaire C et des ouvertures (23) disposées dans le talon B pour donner de la souplesse. Sur la face externe au niveau du talon B, l'élément (20) monopièce remonte à la verticale pour former un premier contrefort (25), alors que sur la face interne, ce contrefort vertical continu s'étend depuis le talon (26) se prolonge sur la zone patin (27) et se termine en (28) à l'avant de la pointe (5). La référence (29) désigne une fente en V ouverte sur le haut, ménagée à hauteur de la partie arrière des métatarses, c'est-à-dire au niveau de l'articulation métatarsophalangienne, destinée à permettre les mouvements de flexion des orteils. Les références (30 et 31) désignent un orifice venu de moulage destiné à recevoir l'axe d'articulation (4). In the practical embodiment illustrated in FIG. 9, the characteristic reinforcing element designated by the reference (20) also forms a buttress. This one-piece element (20) made of plastic by molding, comprises a base (21) intended to be inserted, in particular by gluing, under the first mounting. This base (21) has openings (22) intended to receive a stiffening insert placed at the level of the arch of the foot C and openings (23) arranged in the heel B to give flexibility. On the external face at the level of the heel B , the one-piece element (20) rises vertically to form a first buttress (25), while on the internal face, this continuous vertical buttress extends from the heel (26) extends over the pad area (27) and ends in (28) at the front of the point (5). The reference (29) designates a V-shaped slot open at the top, formed at the level of the rear part of the metatarsals, that is to say at the level of the metatarsophalangeal joint, intended to allow the flexion movements of the toes. The references (30 and 31) designate an orifice molded for receiving the hinge pin (4).

Avantageusement, les portions remontantes (25) et (28) formant les contreforts talon externe (25) et pointe interne (28), présentent une surépaisseur par rapport au reste de la pièce (20), ce qui confère à ces parties une rigidité supérieure. En pratique, la face externe de ces portions (25,28) est granitée. Si le plus généralement, l'élément (20) monopièce est moulé en une seule matière plastique, il peut l'être en deux matières, une matière plus rigide servant à confectionner les parties remontantes caractéristiques (25 et 28) et les parties de liaison.Advantageously, the upward portions (25) and (28) forming the buttresses external heel (25) and internal toe (28), have an additional thickness relative to the rest of the part ( 20 ), which gives these parts greater rigidity. . In practice, the external face of these portions (25,28) is granite. If more generally, the one-piece element (20) is molded from a single plastic material, it can be molded from two materials, a more rigid material used to make the characteristic rising parts (25 and 28) and the connecting parts. .
