The elastic catch is anchored on the fixing device, at the rear of the stop. The elastic catch and anchoring mechanism are longitudinally mobile countering the elastic mechanism.

Description

La présente invention a pour objet un système de fixation d'une chaussure à un article de sport, notamment un sport de glisse tel que le ski de fond, le ski de randonnée (touring), le télémark, le patin à glace ou le patin à roulettes.The present invention relates to a system for attaching a shoe to a sporting article, in particular a sliding sport such as cross-country skiing, ski hiking (touring), telemark, ice skating or roller skating.

Dans les systèmes de fixation de type traditionnel utilisés en ski de fond l'accroche de la chaussure à l'article de sport se fait généralement à l'avant de celle-ci au moyen d'une liaison de type charnière permettant un débattement de la chaussure par rapport à l'article de sport, c'est-à-dire un soulèvement du talon.In traditional fastening systems used in cross-country skiing from the shoe to the sporting article is usually done at the front of it by means of a hinge-type connection allowing the shoe to be deflected by compared to the sporting article, that is to say, raising the heel.

Il est également connu en patin à glace ou à roulettes d'avoir une liaison articulée de la chaussure sur l'article de sport, ce qui permet d'allonger la foulée et d'augmenter la vitesse.He is also known in ice skating or on wheels to have an articulated connection of the shoe on the sports article, which allows to extend the stride and to increase the speed.

De tels systèmes de liaison ont fait leur preuves. Cependant, ils présentent l'inconvénient que la semelle de la chaussure doit être à la fois rigide en direction transversale et en torsion tout en étant suffisamment souple pour permettre, dans la mesure du possible, un déroulement naturel du pied.Such linkage systems have proved their worth. However, they present the disadvantage that the sole of the shoe must be both rigid in the direction of torsionally and torsionally yet flexible enough to allow, in the possible, a natural development of the foot.

Ces exigences étant contradictoires et difficiles à concilier sur un même élément, le contrôle et le guidage du ski ne sont pas toujours assurés de façon optimum.These requirements being contradictory and difficult to reconcile on the same element, the control and guidance of the ski are not always ensured optimally.

D'autre part, les chaussures de tels système comportent généralement un axe transversal placé à l'extrémité avant de la semelle qui peut gêner lors de la marche à pied.On the other hand, the shoes of such systems generally comprise an axis transverse placed at the front end of the sole that can interfere when walking to foot.

EP-768 103 décrit un dispositif de fixation dans lequel la fixation de la chaussure est assuré par une charnière et dans lequel un mécanisme complémentaire à biellette articulèe assure une fonction de contrôle et de rappel elastique.EP-768 103 discloses a fixing device in which the fixing of the shoe is provided by a hinge and in which a complementary mechanism with articulated link provides a function of control and elastic return.

Des problèmes identiques se posent dans les autres domaines et notamment le patinage.Similar problems arise in other areas, including the skating.

Par le WO 96/23558, sur lequel le préambule de la revendication 1 est basé, il a été proposé de lier la partie avant de la chaussure, jusqu'à la zone dite d'articulation métatarsophalangienne, par l'intermédiaire d'un élément élastique ancré à une extrémité à la fixation et qui s'accroche par son extrémité libre dans la semelle de la chaussure, à l'arrière de ladite zone. Cet élément élastique fournit à la chaussure les caractéristiques de rigidité transversale et en torsion souhaitées et exerce en même temps un effort de rappel constant de ladite chaussure vers l'article de sport. Il en résulte un contrôle et guidage améliorés de l'article de sport.By WO 96/23558, on which the preamble of claim 1 is based, it has been proposed to bind the front part of the shoe, up to the so-called metatarsophalangeal joint area, via an element elastic anchored at one end to the binding and which clings by its free end in the sole of the shoe, at the rear of said zone. This elastic element provides the shoe with the characteristics of transverse and torsional stiffness desired and at the same time exerts a constant booster effort of said shoe to the sport article. This results in improved control and guidance of the article of sport.

Cependant, cet élément élastique est soumis à une fatigue importante et une usure rapide du fait des flexions répétées du pied lors de la pratique du sport, de sorte que les caractéristiques de rigidité et de rappel élastique évoquées ci-avant évoluent dans le temps.However, this elastic element is subjected to considerable fatigue and wear because of repeated flexing of the foot during the practice of the sport, so that the characteristics of rigidity and elastic return mentioned above evolve in the weather.

Le but de la présente invention est de remédier à ces inconvénients et de proposer un dispositif de fixation amélioré, conciliant les problèmes de soulèvement du talon de la chaussure, de contrôle en torsion et de fatigue des matériaux.The object of the present invention is to remedy these drawbacks and to propose an improved fixing device, reconciling the problems of heel lift footwear, torsional control and fatigue of materials.

Ce but est atteint dans un dispositif de fixation lié à un article de sport pour y fixer une chaussure comprenant une semelle, le dispositif comportant des moyens de butée destinés à coopérer avec l'extrémité avant de la chaussure, comportant des moyens d'accrochage élastique destinés à coopérer avec des moyens d'accrochage associés de la semelle disposés en arrière de l'extrémité avant de la semelle, et dans lequel lesdits moyens d'accrochage élastiques sont destinés à exercer sur ladite semelle un effort de traction en direction desdits moyens de butée, par le fait que les moyens d'accrochage élastique sont ancrés sur le dispositif de fixation par des moyens d'ancrage articulés agencés en arrière des moyens de butée. This goal is achieved in a fastening device attached to a sports article for attaching a shoe comprising a sole, the device comprising abutment means for to cooperate with the front end of the shoe, comprising means elastic hooking devices intended to cooperate with hooking means associated soleplate disposed rearward of the front end of the soleplate, and wherein said resilient attachment means is for exercising on said sole a tensile force towards said abutment means, in that the elastic coupling means are anchored on the fixing device by articulated anchoring means arranged behind the stop means.

Par cette construction on réduit fortement la sollicitation en flexion des moyens d'accrochage élastique qui de ce fait sont moins soumis à l'usure par fatigue, et d'autre part exercent des efforts de traction et de rappel élastique plus constants.By this construction, the flexural stress of the means is greatly reduced. which are therefore less subject to fatigue wear, and on the other hand exert efforts of traction and elastic return more constant.

Le fait que l'ancrage de moyens d'accrochage élastique est constituée par une articulation permet de s'exonérer totalement de toute énergie liée à la flexion.The fact that the anchoring of elastic attachment means is constituted by a joint allows to totally exonerate any energy related to bending.

Selon un mode de réalisation préféré, les moyens d'ancrage des moyens d'accrochage élastiques sont déplaçables en direction longitudinale à l'encontre de moyens élastiques. Par cette construction on garantit que l'élasticité de rappel lors d'une flexion de la chaussure sera fournie de préférence par la compression de moyens élastiques plutôt que par la flexion des moyens d'accrochage. L'élasticité de rappel sera par conséquent mieux contrôlable.According to a preferred embodiment, the means for anchoring the means snap hooks are movable in the longitudinal direction against elastic means. By this construction it is ensured that the elasticity of return during bending of the shoe will be provided preferably by the compression of elastic means rather than by the flexing of the attachment means. The elasticity of reminder will therefore be better controllable.

De toute façon, l'invention sera mieux comprise et d'autres caractéristique de celle-ci seront mises en évidence à l'aide de la description qui suit en référence aux dessins schématiques annexés en représentant, à titre d'exemple non limitatif, plusieurs modes de réalisation préférés et dans lequel :

  • la figure 1 est une vue en perspective d'un dispositif de fixation selon l'invention en cours de fonctionnement,

  • la figure 5 est une vue en coupe partielle de la partie inférieure de la chaussure,
  • la figure 6 est une vue schématique d'un autre mode de réalisation en cours de fermeture du dispositif de fixation.
In any case, the invention will be better understood and other characteristics thereof will be highlighted with the aid of the description which follows with reference to the attached diagrammatic drawings, showing, by way of nonlimiting example, several preferred embodiments and wherein:
  • FIG. 1 is a perspective view of a fixing device according to the invention during operation,

La figure 1 montre l'application du système de liaison selon l'invention à la liaison à un ski 1 d'une chaussure de ski de fond 10, cette liaison s'effectuant par l'intermédiaire d'un dispositif de fixation 20 et d'une nervure de guidage 70.FIG. 1 shows the application of the connection system according to the invention to the connection to a ski 1 of a cross-country ski boot 10, this connection being made by via a fixing device 20 and a guide rib 70.

Comme le montre la figure 5, la chaussure 10 comporte une semelle 11, munie à l'extrémité avant d'un large rebord périphérique 12 définissant, à sa jonction avec la tige de la chaussure, une gorge 13, et comportant sur toute la longueur de sa face inférieure une rainure longitudinale médiane 14. A son extrémité avant, la semelle 11 remonte en arrondi avec une légère courbure 11a à la manière des chaussures de montagne classiques. La courbure 11a est destinée à faciliter le déroulé de la chaussure ainsi qu'on le verra plus loin.As shown in FIG. 5, the boot 10 comprises a sole 11, provided with the front end of a wide peripheral rim 12 defining, at its junction with the stem of the shoe, a throat 13, and having the entire length of its face lower a middle longitudinal groove 14. At its front end, the sole 11 back in rounded with a slight curvature 11a in the manner of the shoes of mountain classics. The curvature 11a is intended to facilitate the unfolding of the shoe as we will see later.

Un insert 15 est par ailleurs fixé, par exemple par des vis 16 ou encore par surmoulage, au fond de la rainure 14, dans une zone correspondant sensiblement à la zone d'articulation métatarsophalangienne. Cet insert 15 définit un crochet 17 orienté vers l'arrière.An insert 15 is also fixed, for example by screws 16 or by overmoulding, at the bottom of the groove 14, in an area substantially corresponding to the metatarsophalangeal joint area. This insert 15 defines a hook 17 oriented rearward.

Tous ces éléments de la chaussure sont destinés à coopérer avec le dispositif de fixation 20 ainsi qu'on le verra plus loin.All these elements of the shoe are intended to cooperate with the device of fixation 20 as will be seen later.

Comme le montre la figure 2, le dispositif de fixation 20 est constitué d'une embase 21 fixée sur le ski 1 par des vis 22 et sur laquelle est articulé un levier de verrouillage 30, par l'intermédiaire d'un axe 31. Le levier de verrouillage 30 est par ailleurs relié à l'embase 21 par deux biellettes latérales 32, articulées, d'une part, en 33 sur ledit levier 30, et d'autre part, par un axe transversal 34 coulissant dans des lumières latérales 23 de l'embase.As shown in FIG. 2, the fixing device 20 consists of a base 21 fixed on the ski 1 by screws 22 and on which is articulated a locking lever 30, via an axis 31. The locking lever 30 is also connected to the base 21 by two lateral links 32, articulated on the one hand, 33 on said lever 30, and secondly, by a transverse axis 34 sliding in lights 23 side of the base.

L'ensemble levier 30-biellettes 32 forme un système à genouillère dont la ligne de point mort est définie par les axes 31 et 34.The lever assembly 30-links 32 form a toggle system whose line of Neutral is defined by the axes 31 and 34.

Ainsi, lorsque le levier 30 est abaissé dans la position fermée montrée aux figures 3 et 4, les axes d'articulation 33 des biellettes 32 au levier passent en-dessous de ladite ligne de point mort et la position d'équilibre est stable. Le système à genouillère nécessite un certain effort pour passer les axes 33 de part et d'autre de la ligne de point mort et garantit que le levier ne s'ouvrira pas de façon intempestive.Thus, when the lever 30 is lowered into the closed position shown in FIG. 3 and 4, the hinge pins 33 of the links 32 to the lever pass below said neutral line and the equilibrium position is stable. The toggle system requires some effort to pass the axes 33 on either side of the line of neutral and ensures that the lever will not open unexpectedly.

Sur l'axe transversal 34 est par ailleurs monté un coulisseau 35 sensiblement en forme de chape et comportant deux parois longitudinales 36 et une paroi de fond 37. Ce coulisseau 35 reçoit un ressort de compression 38.On the transverse axis 34 is also mounted a slider 35 substantially in clevis shape and having two longitudinal walls 36 and a bottom wall 37. This slider 35 receives a compression spring 38.

Le ressort 38 est maintenu entre le fond 37 du coulisseau, qui comporte une saillie 37a destinée à cet effet, et l'extrémité avant 41 d'un chariot 40. Le chariot 40 est monté coulissant dans l'embase 20 qui comporte à cet effet une glissière de guidage 25 débouchant latéralement sur les côtés de l'embase 20. Sur l'extrémité arrière 42 du chariot 40 est articulé un fil d'accrochage élastique 50 destiné à coopérer avec le crochet 17 de la chaussure.The spring 38 is held between the bottom 37 of the slider, which has a protrusion 37a for this purpose, and the front end 41 of a carriage 40. The carriage 40 is mounted sliding in the base 20 which comprises for this purpose a guide rail 25 opening laterally on the sides of the base 20. On the rear end 42 of the trolley 40 is hinged an elastic attachment thread 50 intended to cooperate with the hook 17 of the shoe.

Le fil d'accrochage élastique 50 a sensiblement la forme d'un U et comporte une branche transversale 52 destinée à coopérer avec le crochet 17 et deux branches latérales 51 dont les extrémités recourbées 53 sont articulées sur le chariot 40.The elastic attachment thread 50 has substantially the shape of a U and comprises a transverse branch 52 intended to cooperate with the hook 17 and two branches lateral 51 whose curved ends 53 are articulated on the carriage 40.

Le dispositif de fixation comporte également des moyens de butée avant constitués en l'occurrence par un étrier 60 comportant une branche horizontale 61 en forme d'arc de cercle épousant la forme de la gorge 13 de la semelle de la chaussure et destinée à recevoir cette dernière et deux branches latérales 62, sensiblement verticales et articulées par leurs extrémités 63, sur l'embase 20. L'étrier 60 est disposé à l'avant du fil d'accrochage élastique 50 et peut donc pivoter autour de ses extrémités 63.The fixing device also comprises front stop means constituted in this case by a stirrup 60 having a horizontal branch 61 in arcuate shape matching the shape of the throat 13 of the sole of the shoe and intended to receive the latter and two lateral branches 62, substantially vertical and articulated by their ends 63, on the base 20. The stirrup 60 is disposed at the front of the elastic attachment thread 50 and can therefore pivot around its ends 63.

Bien entendu, d'autres formes peuvent être envisagées pour l'étrier en fonction de la forme de la semelle.Of course, other forms can be envisaged for the stirrup according to the shape of the sole.

Il peut également être prévu que l'étrier ne coopère pas avec une gorge 13 de la semelle mais simplement avec la surface supérieure du rebord périphérique 12.It can also be expected that the stirrup does not cooperate with a groove 13 of the sole but simply with the upper surface of the peripheral flange 12.

Enfin, le dispositif de fixation comporte une nervure de guidage 70 dont la section transversale correspond à celle de la rainure 14 de la chaussure et dont l'extrémité avant 71 s'ajuste à la partie arrière de l'embase 20 qui forme également une nervure de guidage.Finally, the fixing device comprises a guide rib 70 whose section cross-section corresponds to that of the groove 14 of the boot and whose end before 71 adjusts to the rear portion of the base 20 which also forms a rib guidance.

Le fonctionnement du système de fixation selon l'invention est le suivant. La chaussure 10 est mise en place dans le dispositif de fixation par introduction de l'extrémité avant de sa semelle dans l'étrier 60 jusqu'à ce que la gorge 13 vienne en butée avec la branche horizontale 61 de l'étrier (cf. figure 2).The operation of the fastening system according to the invention is as follows. The shoe 10 is put in place in the fastening device by introduction of the front end of its sole in the stirrup 60 until the groove 13 comes into stop with the horizontal arm 61 of the stirrup (see Figure 2).

Le verrouillage de la chaussure s'effectue alors par abaissement du levier 30 ce qui a pour effet de tirer vers l'avant le chariot 40 et donc le fil d'accrochage 50 jusqu'à ce que sa branche 52 vienne se loger dans le fond du crochet 17 (cf. figure 3).The locking of the shoe is then effected by lowering the lever 30 which has the effect of pulling forward the carriage 40 and thus the attachment thread 50 until that its branch 52 is housed in the bottom of the hook 17 (see Figure 3).

Ce mouvement de fermeture est aidé par le ressort 38 qui tend à repousser le chariot 40 vers l'avant. Le ressort 38 permet de compenser également les cales de neige éventuelles se formant dans la semelle de la chaussure.This closing movement is assisted by the spring 38 which tends to repel the trolley 40 forward. The spring 38 compensates also the wedges of possible snow forming in the sole of the shoe.

Lors de la pratique du ski, la chaussure dont le talon reste libre peut fléchir en entraínant dans sa course le fil d'accrochage 50 qui à la fois coulisse dans l'embase 20 vers l'arrière en comprimant le ressort 38 par l'intermédiaire du chariot 40 et pivote vers le haut autour de ses extrémités 53 (cf. Figure 4).When skiing, the shoe whose heel remains free can flex in driving in its stroke the attachment wire 50 which both slides in the base 20 towards the rear by compressing the spring 38 via the carriage 40 and pivots upwards around its ends 53 (see Figure 4).

Le ressort 38 fournit alors l'énergie de rappel de la chaussure vers la surface supérieure du ski puisqu'il tend à se détendre et donc à ramener le fil d'accrochage 50 vers l'avant.The spring 38 then provides the return energy of the shoe to the surface ski since it tends to relax and therefore bring back the hanging wire 50 forward.

L'énergie de rappel n'est donc pas fournie par une déformation élastique du fil 50 qui vieillit donc beaucoup mieux.The return energy is therefore not provided by an elastic deformation of the wire 50 who gets older so much better.

Par ailleurs, cette énergie de rappel est complètement définie puisque donnée par la compression d'un ressort de compression 38 et est mieux contrôlée et contrôlable que si elle était fournie par la flexion d'un fil comme dans l'art antérieur.Moreover, this recall energy is completely defined since given by the compression of a compression spring 38 and is better controlled and controllable that if it was provided by bending a wire as in the prior art.

Par ailleurs, le déplacement, vers l'arrière par rapport aux moyens de butée avant 60, de l'ancrage 53 du fil ressort fournit une triangulation permettant un meilleur maintien de la chaussure notamment en direction transversale.Moreover, the displacement, towards the rear with respect to the means of front stop 60, the anchor 53 of the spring wire provides a triangulation allowing a better maintaining the boot especially in transverse direction.

Cette triangulation et notamment l'ancrage articulé du fil d'accrochage 50 par ses extrémités 53, permet également un plus grand débattement en flexion de la chaussure, ce qui est recherché pour une utilisation ski de fond. This triangulation and in particular the articulated anchoring of the attachment thread 50 by its ends 53, also allows greater deflection in bending of the shoe, which is sought for use cross-country skiing.

On notera que l'ancrage articulé de l'étrier 60 sur l'embase 20, combiné à la forme arrondie 11a de l'avant de la semelle, permettant un léger pivotement de celui-ci vers l'avant lors d'un pivotement de la chaussure, et permet donc d'accompagner le mouvement de déroulement de la chaussure en fin de foulée et donc d'augmenter encore l'amplitude de la foulée. En pratique, une augmentation de l'ordre de 10 à 15° de débattement de la chaussure en fin de foulée peut être obtenue grâce à la forme arrondie 11a de la semelle de celle-ci à l'avant, ce qui est particulièrement intéressant.It will be noted that the articulated anchorage of the stirrup 60 on the base 20, combined with the shape rounded 11a of the front of the sole, allowing a slight pivoting thereof towards the front during a pivoting of the shoe, and thus allows to accompany the movement of the shoe at the end of the stride and therefore increase still the amplitude of the stride. In practice, an increase of the order of 10 to 15 ° of movement of the shoe at the end of the stride can be obtained thanks to the shape rounded 11a of the sole thereof at the front, which is particularly interesting.

Enfin, la présence sur toute la longueur de la semelle de la chaussure de la nervure de guidage 70, qui se prolonge par la partie arrière de l'embase 21 jusqu'à l'extrémité avant de la chaussure, permet de contrôler le déroulement de la chaussure jusqu'à la fin du mouvement, en lui fournissant un appui et une butée en direction transversale.Finally, the presence along the entire length of the shoe sole of the rib 70, which extends from the rear portion of the base 21 to the end front of the shoe, to control the progress of the shoe to the end of the movement, providing support and a stop in the direction cross.

Comme le montre notamment la figure 1, la nervure de guidage 70 est interrompue dans la zone des métatarses pour le passage du fil d'accrochage 50 et du crochet associé de la chaussure.As shown in particular in FIG. 1, the guide rib 70 is interrupted in the area of the metatarsals for the passage of the attachment wire 50 and the associated hook of the shoe.

Les formes de l'arête de guidage sont par ailleurs conçues pour optimiser le guidage de la chaussure.The shapes of the guide edge are also designed to optimize the guiding the shoe.

La figure 6 illustre de façon schématique un second mode de réalisation dans lequel les éléments similaires ou identiques sont désignés par les mêmes références augmentées de 100.Figure 6 schematically illustrates a second embodiment in which similar or identical elements are designated by the same references increased by 100.

En fait, ce système de fixation comporte les mêmes éléments de verrouillage, à savoir étrier de butée avant 160 articulé en 163, fil d'accrochage 150 relié à un chariot 140, qui est monté coulissant, est sollicité vers l'avant par un ressort 138 et dont le déplacement en direction longitudinale est commandé par un levier 130.In fact, this fastening system has the same locking elements, know front caliper 160 hinged 163, 150 hanging wire connected to a trolley 140, which is slidably mounted, is urged forward by a spring 138 and whose displacement in the longitudinal direction is controlled by a lever 130.

La différence essentielle réside en fait dans la position des articulations 131 et 134 du levier 130 et des biellettes 132 qui sont situées à l'arrière du ressort 138. Le fonctionnement est par ailleurs identique.The essential difference lies in fact in the position of joints 131 and 134 lever 130 and links 132 which are located at the rear of the spring 138. The operation is otherwise identical.
