Description

Dispositif de liaison d'une chaussure à un article de sport Device for connecting a shoe to a sporting article
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 subject of the present invention is a system for attaching a shoe to a sporting article, in particular a gliding sport such as cross-country skiing, touring ski (touring), telemark, ice skating or skating. on casters.
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 type fastening systems used in cross-country skiing, the boot is attached to the sporting article generally in front of it by means of a hinge-type connection allowing movement of the shoe compared to the sports article, that is to say a heel lift.
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.It is also known in ice or roller skating to have an articulated connection of the shoe on the sports article, which makes it possible to lengthen 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 proven themselves. However, they have the drawback that the sole of the shoe must be both rigid in transverse direction and in torsion while being flexible enough to allow, as far as possible, a natural unfolding 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 in an optimum manner.
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 a system generally have a transverse axis placed at the front end of the sole which can hinder when walking.
Des problèmes identiques se posent dans les autres domaines et notamment le patinage.Identical problems arise in other fields and in particular skating.
Par le WO 96/23558, 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, it has been proposed to link the front part of the shoe, up to the so-called metatarsophalangeal articulation zone, by means of an elastic element anchored at one end to the binding and which s 'grips by its free end in the sole of the shoe, at the rear of said zone. This elastic element provides the shoe with the desired transverse stiffness and torsional characteristics and at the same time exerts a constant effort to return said shoe to the sports article. This results in improved control and guidance of the sports article.
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 subject to significant fatigue and rapid wear due to repeated flexions of the foot during the practice of sport, so that the characteristics of rigidity and elastic return mentioned above evolve over time.
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 fastening device, reconciling the problems of lifting the heel of the shoe, controlling torsion and fatigue of the materials.
Ce but est atteint dans de dispositif de fixation du système selon l'invention qui est du type comportant des moyens de butée avant coopérant avec l'extrémité avant de la chaussure et des moyens d'accrochage élastique coopérant avec des moyens d'accrochage de la semelle associés disposés en arrière de l'extrémité avant de la semelle et exerçant 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, en arrière des moyens de butée avant.This object is achieved in the device for fixing the system according to the invention which is of the type comprising front stop means cooperating with the front end of the shoe and elastic fastening means cooperating with associated sole fastening means disposed behind the front end of the sole and exerting on said sole a tensile force in the direction of said abutment means, thereby that the elastic hooking means are anchored on the fixing device, behind the front 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 bending stress of the elastic fastening means is greatly reduced, which is therefore less subject to wear by fatigue, and on the other hand exerts more constant tensile and elastic return forces.
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 anchoring means of the elastic hooking means can be moved in the longitudinal direction against elastic means. By this construction, it is guaranteed that the return elasticity during a bending of the shoe will preferably be provided by the compression of elastic means rather than by the bending of the fastening means. The elasticity of return will therefore be better controllable.
Avantageusement aussi, l'ancrage de moyens d'accrochage élastique est constituée par une articulation, ce qui permet de s'exonérer totalement de toute énergie liée à la flexion.Advantageously also, the anchoring of elastic attachment means is constituted by a hinge, which makes it possible to be completely exempt from any energy linked to bending.
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 :In any case, the invention will be better understood and other characteristics of it will be highlighted with the aid of the description which follows with reference to the appended schematic drawings showing, by way of nonlimiting example, several preferred embodiments and in which:

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 effected by means of a fastening device 20 and d '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 lia à la manière des chaussures de montagne classiques. La courbure lia est destinée à faciliter le déroulé de la chaussure ainsi qu'on le verra plus loin.As shown in Figure 5, the shoe 10 has a sole 11, provided at the front end with a wide peripheral rim 12 defining, at its junction with the upper of the shoe, a groove 13, and comprising over the entire length from its underside a median longitudinal groove 14. At its front end, the sole 11 rises in roundness with a slight curvature 11a in the manner of the shoes of classic mountains. The curvature 11a is intended to facilitate the unwinding of the shoe as will be seen below.
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 even by overmolding, at the bottom of the groove 14, in an area corresponding substantially to the metatarsophalangeal articulation area. This insert 15 defines a hook 17 oriented towards the rear.
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 fastening device 20 as will be seen below.
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 to the ski 1 by screws 22 and on which a locking lever 30 is articulated, by means of an axis 31. The locking lever 30 is also connected to the base 21 by two lateral links 32, articulated, on the one hand, at 33 on said lever 30, and on the other hand, by a transverse axis 34 sliding in lateral openings 23 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 30-link 32 assembly forms a toggle joint system, the neutral line of which 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 Figures 3 and 4, the hinge pins 33 of the rods 32 to the lever pass below said neutral line and the equilibrium position is stable. The toggle joint system requires a certain effort to pass the axes 33 on either side of the neutral line and guarantees that the lever will not open inadvertently.
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 slide 35 substantially in the form of a yoke and comprising two longitudinal walls 36 and a bottom wall 37. This slide 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 slide, which has a projection 37a intended for this purpose, and the front end 41 of a carriage 40. The carriage 40 is slidably mounted in the base 20 which comprises for this purpose a guide slide 25 opening laterally on the sides of the base 20. On the rear end 42 of the carriage 40 is articulated an elastic hooking wire 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 hooking wire 50 has substantially the shape of a U and comprises a transverse branch 52 intended to cooperate with the hook 17 and two lateral branches 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 4The fastening device also comprises front stop means constituted in this case by a stirrup 60 comprising a horizontal branch 61 in the form of an arc of a circle matching the shape of the groove 13 of the sole of the shoe and intended to receive this last and two lateral branches 62, substantially vertical and articulated by their ends 63, on the base 20. The stirrup 60 is disposed 4
à l'avant du fil d'accrochage élastique 50 et peut donc pivoter autour de ses extrémités 63.at the front of the elastic hooking wire 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 shapes can be envisaged for the stirrup depending on 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 provided that the stirrup does not cooperate with a groove 13 in the sole but simply with the upper surface of the peripheral rim 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 fastening device comprises a guide rib 70 whose cross section corresponds to that of the groove 14 of the shoe and whose front end 71 adjusts to the rear part of the base 20 which also forms a rib guide.
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 fixing system according to the invention is as follows. The shoe 10 is put into place in the fastening device by introducing the front end of its sole into the stirrup 60 until the groove 13 abuts with the horizontal branch 61 of the stirrup (cf. 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 shoe is then locked by lowering the lever 30, which has the effect of pulling the carriage 40 forward and therefore the hooking wire 50 until its branch 52 comes to lodge in the bottom. 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 helped by the spring 38 which tends to push the carriage 40 forward. The spring 38 also makes it possible to compensate for any snow wedges forming in the sole of the shoe.
Lors de la pratique du ski, la chaussure dont le talon reste libre peut fléchir en entraînant 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).During skiing, the boot, the heel of which remains free, can bend, dragging in its course the fastening wire 50 which both slides in the base 20 towards the rear while compressing the spring 38 via of the carriage 40 and pivots upwards around its ends 53 (cf. FIG. 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 supplies the energy for returning the boot to the upper surface of the ski since it tends to relax and therefore to bring the fastening 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 which therefore ages 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.Furthermore, this return energy is completely defined since it is given by the compression of a compression spring 38 and is better controlled and controllable than if it were provided by the bending of 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.Furthermore, the movement, rearwardly relative to the front stop means 60, of the anchor 53 of the spring wire provides a triangulation allowing better retention of the shoe in particular 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. 5This triangulation and in particular the articulated anchoring of the hooking wire 50 by its ends 53, also allows greater deflection in flexion of the boot, which is sought after for cross-country skiing use. 5
On notera que l'ancrage articulé de l'étrier 60 sur l'embase 20, combiné à la forme arrondie lia 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 lia de la semelle de celle-ci à l'avant, ce qui est particulièrement intéressant.It will be noted that the articulated anchoring of the stirrup 60 on the base 20, combined with the rounded shape 11a of the front of the sole, allowing a slight pivoting of the latter towards the front during a pivoting of the shoe, and therefore makes it possible to accompany the movement of unwinding of the shoe at the end of the stride and therefore to further increase 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 rounded shape 11a of the sole thereof at the front, which is particularly advantageous.
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 over the entire length of the sole of the shoe of the guide rib 70, which is extended by the rear part of the base 21 to the front end of the shoe, makes it possible to control the progress of the shoe until the end of the movement, providing it with support and a stop in the transverse direction.
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 Figure 1, the guide rib 70 is interrupted in the metatarsal area 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 guidance of 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.FIG. 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 fixing system includes the same locking elements, namely front stop stirrup 160 articulated in 163, hooking wire 150 connected to a carriage 140, which is slidably mounted, is biased forward by a spring. 138 and whose movement 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 resides in fact in the position of the joints 131 and 134 of the lever 130 and of the rods 132 which are situated at the rear of the spring 138. The operation is moreover identical.
Bien entendu, la présente invention n'est pas limitée aux modes de réalisation décrites ci-avant à titre d'exemple non limitatif mais en englobe tous les modes de réalisation similaires ou équivalents. Of course, the present invention is not limited to the embodiments described above by way of nonlimiting example, but encompasses all similar or equivalent embodiments.
