Abstract

The fastening consists of at least one strap (3) situated in the instep zone of the boot, made with a supple and flexible padding (6) on the boot side of the strap. The padding is designed to distribute the pressure from the strap against the instep so that the central pressure zone corresponding to the position of the big toe tendon is lower that the lateral pressure on either side of it. The strap's pressure distribution is achieved by having a central recess in the padding and thicker portions on either side of it to create a space for the tendon. The thicker portions are ovoid in shape, with their tips towards the central recess so that they conform to the ergonomic shape of the instep. The padding can be made from materials of different densities, with a lower density material in the middle of the strap which is able to compress to absorb the tendon, produced e.g. by moulding or sewing a foam material inside a flexible sleeve.

Description

La présente invention concerne un dispositif de liaison d'une chaussure de sport à associer à une planche de glisse pour la pratique du surf sur la neige, la chaussure comprenant une tige solidaire d'une semelle destinée à coopérer directement ou indirectement avec la planche.The present invention relates to a device for connecting a sports shoe to combine with a gliding board for snowboarding, the shoe including a rod secured to a sole intended to cooperate directly or indirectly with the board.

Pour la pratique de cette discipline, il existe plusieurs systèmes différents de fixation d'une chaussure sur une planche.For the practice of this discipline, there are several different systems of fixing a shoe on a board.

Un premier système concerne la liaison de chaussures rigides du type alpin attachées à la planche par des éléments d'étrier avant et arrière et dont la commande de verrouillage est située sur l'un des étriers avec une action manuelle ou automatique. Ce système n'est pas le plus répandu du fait que la rigidité des chaussures procurent des désavantages importants en terme de fonction et de confort.A first system relates to the binding of rigid alpine type shoes attached to the board by front and rear stirrup elements and the control of which lock is located on one of the stirrups with manual or automatic action. This system is not the most widespread because the stiffness of the shoes provide significant disadvantages in terms of function and comfort.

Le système actuel le plus répandu concerne les dispositifs de fixation de chaussures souples sur la planche par une coque fixée à la planche. Cette coque comporte un certain nombre de sangles destinées à solidariser la chaussure dans la coque. La présente invention se rapporte plus particulièrement à ce deuxième type de dispositif de fixation.The most widespread current system concerns fixing devices for flexible shoes on the board by a shell attached to the board. This shell has a number of straps intended to secure the shoe in the shell. The current The invention relates more particularly to this second type of fixing device.

Une coque de ce type est décrite par exemple dans le brevet américain n° 5 356 170 ou dans le modèle d'utilité allemand G 91 13 766.A shell of this type is described for example in US patent 5,356 170 or in the German utility model G 91 13 766.

Le document allemand divulgue une fixation qui comprend deux sangles. L'une des sangles présente une largeur sensiblement constante, tandis que l'autre présente une largeur variable due à sa forme elliptique. Cette dernière sangle permet une répartition de la pression de serrage exercée par la sangle sur le cou-de-pied de la chaussure.The German document discloses a binding which includes two straps. Moon straps have a substantially constant width, while the other has a variable width due to its elliptical shape. This last strap allows a distribution of the tightening pressure exerted by the strap on the instep of the shoe.

Bien entendu, l'invention ne se rapporte pas uniquement à la liaison d'une chaussure sur une coque mais à toute liaison d'une chaussure sur une planche de glisse en général, comportant au moins un élément de sanglage destiné au serrage de la chaussure relativement à la planche, plus particulièrement, par l'intermédiaire d'au moins une sangle disposée au niveau du cou-de-pied.Of course, the invention does not relate solely to the binding of a shoe on a shell but at any connection of a shoe on a board general, comprising at least one strap element intended for tightening the shoe relatively to the board, more particularly, by means of at least one strap arranged at the instep.

Ce type de sangle est généralement rigide et doublée d'un rembourrage interne relativement souple dirigé vers la chaussure au niveau dudit cou-de-pied.This type of strap is generally rigid and lined with internal padding relatively flexible directed towards the shoe at the level of said instep.

Il a pu être constaté que si ce rembourrage apporte un certain confort d'utilisation, en revanche il n'est pas complètement assuré dans certains cas de figures comme lors par exemple, de la flexion de la chaussure vers l'avant au cours de la pratique du surf.It has been found that if this padding provides a certain comfort of use, on the other hand it is not completely insured in certain cases of figures as during by example, bending the shoe forward during surfing.

En effet, dans cette position le tendon releveur du gros orteil qui travaille en flexion du pied, se trouve prohéminent sur le coup de pied et le serrage appliqué par la sangle sur ledit tendon provoque une irritation, voire dans certains cas une douleur. Par conséquent, et selon une première phase de la démarche inventive, il a été recherché, sur la base de ces constatations, de répartir les pressions de serrage de la sangle de façon à éviter d'exercer une pression sur ledit tendon.In fact, in this position, the large tendon toe which works in flexion of the foot, is prominent on the kick and the tightening applied by the strap on said tendon causes irritation, even in some cases a pain. Consequently, and according to a first phase of the inventive step, it was sought, on the basis of these findings, to distribute the tightening pressures of the strap so as to avoid exerting pressure on said tendon.

A cet effet, l'invention concerne un dispositif de liaison d'une chaussure de sport muni d'au moins une sangle comprenant un rembourrage du type précité se caractérisant en ce que ledit rembourrage de la sangle comporte des moyens de répartition de la pression de serrage exercée par celle-ci sur le cou-de-pied, de manière à obtenir une pression centrale correspondant à la zone du tendon du gros orteil, inférieure aux pressions latérales exercées de part et d'autre de celui-ci.To this end, the invention relates to a device for binding of a sports shoe provided with at least one strap comprising padding of the aforementioned type, characterized in that that said padding of the strap comprises means of distribution of the clamping pressure exerted by it on the instep, so as to obtain a central pressure corresponding to the area of the tendon of the big toe, less than lateral pressures exerted on either side of it.

Parmi un mode préféré de réalisation, les moyens de répartition de la pression de la sangle sur l'élément de rembourrage comprennent un espace central en creux délimité latéralement par deux formes en relief latérales en proéminence de part et d'autre dudit espace central, de manière à constituer un logement au tendon du gros orteil. De ce fait, la forme de la sangle en contact avec la partie correspondante de la chaussure est adaptée de façon à tenir compte des spécificités anatomiques de la région recouverte.Among a preferred embodiment, the means of distribution of the pressure of the strap on the element of padding include a delimited hollow central space laterally by two prominent lateral relief shapes on either side of said central space, so as to constitute a big toe tendon housing. Therefore, the shape of the strap in contact with the corresponding part of the shoe is adapted to take into account anatomical specificities of the region covered.

D'autres caractéristiques de ce mode ainsi que d'autres exemples possibles de réalisation seront énoncés dans la description qui sera faite plus loin.Other features of this mode as well as others possible examples of achievement will be set out in the description which will be given later.

On comprend aisément que selon la solution de l'invention consistant à utiliser des moyens de répartition de pression sur une partie anatomique du pied; il faille centrer de manière précise la sangle pour que la zone de moindre pression se situe à l'endroit exact du tendon et non pas décalée par rapport à celui-ci.It is easy to understand that according to the solution of the invention consisting in using means for distributing pressure on an anatomical part of the foot; you have to center from precisely the strap so that the area of least pressure is located at the exact location of the tendon and not offset by compared to this one.

Pour cela, les moyens de serrage de la sangle sur le cou-de-pied, actuellement connus, ne permettent pas d'obtenir un tel résultat, tout au moins de manière efficace et rapide. For this, the means of tightening the strap on the instep, currently known, do not make it possible to obtain a such a result, at least efficiently and quickly.

De manière connue, la sangle comprend, en général, deux parties distinctes; chacune reliée sur un côté de la coque ou embase de fixation et qui ont deux extrémités libres reliées ensembles et ajustables au serrage par un moyen de fermeture du type à cliquet, par exemple. L'une des partie de sangle comprend le rembourrage qui supporte le moyen de fermeture; tandis que l'autre, est une portion dentée coopérant par incrémentation avec le moyen de fermeture.In known manner, the strap generally comprises two separate parts; each connected on one side of the hull or mounting base and which have two connected free ends sets and adjustable to tightening by means of closure of the ratchet type, for example. One of the strap parts includes the padding which supports the closure means; while the other, is a toothed portion cooperating by incrementation with the closing means.

On comprend bien que le serrage obtenu par traction unilatéral sur la partie portant le rembourrage qui est attaché par ailleurs à son autre extrémité à une partie fixe de la coque, ne permet pas une possibilité de réglage correct du centrage de ladite partie rembourrée pour s'adapter à différents volumes de chaussure à serrer.We understand that the tightening obtained by traction unilateral on the part carrying the padding which is attached furthermore at its other end to a fixed part of the shell, does not allow a possibility of correct adjustment of the centering said padded part to adapt to different shoe volumes to be tightened.

Il est connu également un dispositif de liaison d'une chaussure sur une planche dans lequel la sangle, toujours en deux parties, comporte d'une part un premier moyen de serrage agissant aux extrémités libres des deux parties de sangle et un moyen de centrage disposé au niveau de l'extrémité de la partie de sangle portant le rembourrage solidaire d'une partie fixe de la coque. Ces derniers moyens sont constitués par une pluralité de trous que l'on choisit en fonction du centrage souhaité.It is also known a device for connecting a shoe on a board in which the strap, still in two parts, comprises on the one hand a first clamping means acting at the free ends of the two strap parts and a centering means arranged at the end of the part strap carrying the padding integral with a fixed part of shell. These latter means are constituted by a plurality of holes that are chosen according to the desired centering.

Un tel moyen est utile pour le réglage de longueur de la sangle mais s'avère inadapté pour régler le centrage de la partie rembourrée de manière efficace et rapide. L'intervention sur les moyens de réglage du centrage par l'intermédiaire d'une pluralité de trous implique une intervention longue et fastidieuse à ce niveau.Such a means is useful for adjusting the length of the strap but is unsuitable for adjusting the centering of the part padded efficiently and quickly. The intervention on the centering adjustment means by means of a plurality of holes requires a long intervention and tedious at this level.

Pour remédier à cet inconvénient et selon une autre caractéristique de l'invention, la partie de rembourrage est réalisée sur une armature ou élément de support amovible interposé entre deux parties crantées de sangle pour constituer un troisième élément central dont les extrémités sont reliées aux extrémités libres desdites deux parties crantées de sangle par l'intermédiaire de deux moyens de verrouillage distincts permettant ainsi un centrage plus facile et plus rapide de l'élément de support rembourré par rapport au cou-de-pied.To remedy this drawback and according to another characteristic of the invention, the padding part is made on a removable frame or support element interposed between two notched parts of strap to constitute a third central element whose ends are connected at the free ends of said two notched strap parts by means of two separate locking means allowing easier and faster centering of the support element padded with respect to the instep.

La présente invention concerne également les caractéristiques qui ressortiront au cours de la description qui va suivre et qui devront être considérées isolément ou selon toutes leurs combinaisons techniques possibles.The present invention also relates to characteristics which will emerge during the description which will follow and which should be considered in isolation or according to all their possible technical combinations.

This description given by way of nonlimiting example will make it easier to understand how the invention can be produced with reference to the attached drawings in which:
  • Figure 1 shows in perspective a portion of the gliding board on which is disposed a shell for fixing a shoe provided with a connecting device, according to the invention;
  • Figure 2 is a front plan view of a central portion of the strap constituting the pressure distribution means according to an exemplary embodiment;

  • Figure 6 is a partial top view of a strap portion according to a different embodiment of the invention;
  • FIG. 7 is a side view of the strap portion of FIG. 6.

La figure 1 représente une portion de planche de glisse 1 sur laquelle est disposée une coque 2 destinée à retenir une chaussure (non représentée). La coque 2 comporte un dispositif de liaison avec la chaussure qui comprend deux sangles 3 et 4. La sangle 3 est destinée à enserrer une chaussure au niveau du cou-de-pied tandis que l'autre sangle 4 est destinée à enserrer la partie de chaussure au niveau de l'avant du pied au niveau des orteils. L'invention se rapporte uniquement à la sangle 3 qui est semi-rigide et comporte un élément de support 5 doublé d'un rembourrage interne relativement souple sous forme d'un élément de rembourrage 6 rattaché à l'élément de support 5 et dirigé vers la chaussure.Figure 1 shows a portion of gliding board 1 on which is placed a shell 2 intended to retain a shoe (not shown). Shell 2 has a device connecting with the shoe which includes two straps 3 and 4. The strap 3 is intended to grip a shoe at the level of the instep while the other strap 4 is intended to grip the shoe part at the level of the forefoot at the level toes. The invention relates only to strap 3 which is semi-rigid and has a lined support element 5 relatively soft internal padding in the form of a padding element 6 attached to the support element 5 and directed towards the shoe.

L'élément de support 5 est, de préférence, une pièce sous forme d'une bande flexible résistante à la traction réalisée, de préférence, en matière plastique. The support element 5 is preferably a piece in the form of a flexible tensile strip preferably made of plastic.

La sangle 3 comprend, par ailleurs, deux parties crantées de sangle 30, 31 disposées de part et d'autre de l'élément de support 5 et dont les extrémités de la sangle 3 sont reliées sur les côtés latéraux 20, 21 de la coque 2 par l'intermédiaire d'articulations 7.The strap 3 also comprises two parts notched strap 30, 31 arranged on either side of the support element 5 and whose ends of the strap 3 are connected on the lateral sides 20, 21 of the shell 2 by through joints 7.

La sangle 3 comporte également des moyens de verrouillage 8 et 9, du type verrou à cliquet, fixés sur les deux extrémités de l'élément de support 5 et qui coopèrent par incrémentation avec les extrémités libres des deux parties de sangle crantées 30, 31 pour permettre la libération de la chaussure ou son immobilisation après une opération de serrage progressif s'effectuant, par exemple, par traction sur lesdites parties de sangle 30, 31 en direction l'une de l'autre.The strap 3 also includes means for lock 8 and 9, of the ratchet lock type, fixed on the two ends of the support element 5 and which cooperate by increment with the free ends of the two parts of notched strap 30, 31 to allow the release of the shoe or its immobilization after a tightening operation progressive, for example by pulling on said strap parts 30, 31 towards each other.

Selon l'invention, l'élément de rembourrage interne 6 de la sangle 3 comporte des moyens de répartition de la pression pour répartir la pression de serrage qui s'exerce par la sangle sur le cou-de-pied, de manière à obtenir une pression centrale correspondant à la zone du tendon releveur du gros orteil, inférieure aux pressions latérales exercées de part et d'autre de celui-ci.According to the invention, the internal padding element 6 of the strap 3 includes means for distributing the pressure to distribute the tightening pressure exerted by the strap on the instep, so as to obtain a central pressure corresponding to the area of the big toe lifting tendon, lower than the lateral pressures exerted on both sides of it.

Selon l'exemple de réalisation représenté sur les figures 2, 3 et 4, les moyens de répartition de la pression de la sangle 3 de l'élément de rembourrage interne 6 sont constitués par un espace central en creux 10 délimité latéralement par deux formes en relief latérales 11 et 12 ménagés en proéminence de part et d'autre dudit espace 10, de manière à constituer un logement au tendon du gros orteil.According to the embodiment shown in the Figures 2, 3 and 4, the means for distributing the pressure of the strap 3 of the internal padding element 6 are constituted by a hollow central space 10 delimited laterally by two lateral raised shapes 11 and 12 arranged in prominence on either side of said space 10, so as to constitute a housing for the tendon of the big toe.

Selon un exemple préféré de réalisation, les formes en relief latérales 11 et 12 ont une forme fuyante globalement ovoïde dont le sommet 11a et 12a est dirigé vers l'espace central 10 de manière à s'adapter à l'ergonomie du pli de flexion du coup de pied. L'élément 6 peut être réalisé d'une seule pièce allongée et conformée de manière à présenter la forme générale recherchée.According to a preferred embodiment, the shapes in lateral reliefs 11 and 12 have a generally leaky shape ovoid whose apex 11a and 12a is directed towards space central 10 so as to adapt to the ergonomics of the fold flexion of the kick. Element 6 can be made of single piece elongated and shaped so as to present the general shape sought.

Comme le montre la figure 2, l'élément de support 5 comporte des lumières 50, 51 espacées longitudinalement dans lesquelles prennent position des bourrelets 60, 61 de l'élément de rembourrage 6 de forme complémentaire à la forme des lumières 50, 51 de façon à faciliter le positionnement et augmenter l'accrochage de l'élément de rembourrage 6 sur l'élément de support 5.As shown in Figure 2, the support member 5 includes lights 50, 51 spaced longitudinally in which take position of the beads 60, 61 of the element padding 6 of complementary shape to the shape of the lights 50, 51 so as to facilitate positioning and increase the attachment of the padding element 6 to the support element 5.

L'élément de rembourrage 6 est obtenu par moulage d'au moins une pièce en mousse, de préférence, enveloppée dans une enveloppe souple et rapportée sur la sangle 3 par tout moyen de fixation.The padding element 6 is obtained by molding at least minus a piece of foam, preferably wrapped in a flexible envelope and attached to the strap 3 by any means of fixation.

L'enveloppe souple peut, par exemple, être choisi parmi les films plastiques souples tel que le PVC, les films en textile synthétique ou naturel, ou encore le cuir. l'assemblage de l'enveloppe sur la mousse peut être réalisée par différents moyens; comme par couture ou collage.The flexible envelope can, for example, be chosen from flexible plastic films such as PVC, films made of synthetic or natural textile, or leather. assembly of the envelope on the foam can be made by different means; as by sewing or gluing.

De même les moyens de fixation de l'élément de rembourrage 6 sur l'élément de support 5 de la sangle 3 peuvent être constitués par une couture, un rivetage, par collage, ou encore par soudage utilisant les hautes fréquences.Likewise the means for fixing the element of padding 6 on the support element 5 of the strap 3 can be formed by sewing, riveting, gluing, or again by welding using high frequencies.

Le rembourrage 6 peut aussi être obtenu par surmoulage d'une même mousse de même densité ou de densité différente selon les cas, réalisée directement sur l'élément de support 5 de la sangle 3. Parmi les mousses choisies; on peut citer l'emploi de polyuréthanne ou de polyéthylène.The padding 6 can also be obtained by overmolding of the same foam of the same density or of different density depending on the cases, carried out directly on the support element 5 of the strap 3. Among the foams chosen; we can cite the use of polyurethane or polyethylene.

Selon une autre caractéristique avantageuse de l'invention autorisant un positionnement adéquat et centrée de la sangle , l'élément de support 5 est interposé entre les deux parties de sangle 30, 31 pour en constituer un troisième élément central. Les extrémités Sa, 5b de l'élément de support 5 sont reliées aux extrémités libres desdites deux parties crantées 30, 31 de la sangle 3 par l'intermédiaire des deux moyens de verrouillage distincts 8, 9 fixés sur lesdites extrémitées 5a, 5b.According to another advantageous characteristic of the invention authorizing an adequate and centered positioning of the strap, the support element 5 is interposed between the two strap parts 30, 31 to form a third element central. The ends Sa, 5b of the support element 5 are connected to the free ends of said two notched parts 30, 31 of the strap 3 via the two means of separate locks 8, 9 fixed on said ends 5a, 5b.

De cette manière, les deux moyens de verrouillage 8, 9 peuvent agir de manière indépendante sur le centrage de l'élément de support rembourré 5 par rapport au cou-de-pied.In this way, the two locking means 8, 9 can act independently on the centering of the padded support member 5 with respect to the instep.

Par exemple, les moyens de verrouillage 8 et 9 sont constitués d'un côté, d' un dispositif d'avancée incrémentielle 8 muni d'un levier de maneuvre et d'un cliquet; du type tel que connu et décrit dans le brevet américain n° 5 416 952 permettant d'obtenir un serrage progressif et de l'autre côté, d'un dispositif de réglage à cliquet simple 9 permettant, indépendamment du moyen précédent, d'obtenir le centrage de l'élément de support 5 d'où de l'élément de rembourrage 6 par rapport au tendon releveur du gros orteil. La sangle peut aussi comprendre des moyens à cliquet simples des deux côtés ou encore des moyens de verrouillage d'un autre type.For example, the locking means 8 and 9 are consisting on one side of an incremental advancement device 8 provided with an operating lever and a pawl; of the type such as known and described in US Patent No. 5,416,952 allowing to obtain a progressive tightening and on the other side, a simple ratchet adjustment device 9 allowing, regardless of the previous means, to obtain the centering of the support element 5 hence the padding element 6 by compared to the big toe lift tendon. The strap can also include simple ratchet means on both sides or alternatively locking means of another type.

Comme le montre les figures 2, 3 et 4, l'élément de support rembourré amovible 5, constituant la partie centrale de la sangle 3, est asymétrique par rapport à l'axe longitudinal médian de manière à la rendre réversible et offrir ainsi selon le côté choisi une rigidité et une souplesse relative afin de constituer des prises d'appui différentes dont le choix est effectué par l'utilisateur.As shown in Figures 2, 3 and 4, the element of removable padded support 5, constituting the central part of the strap 3 is asymmetrical with respect to the longitudinal axis median so as to make it reversible and thus offer according to the side chosen a relative rigidity and flexibility in order to constitute different support points, the choice of which is performed by the user.

C'est ainsi que selon un exemple de réalisation des figures, l'élément de support 5 comporte un côté longitudinal concave 5c constituant la prise d'appui souple et un côté longitudinal opposé convexe 5d constituant la prise d'appui rigide.Thus, according to an exemplary embodiment of the figures, the support element 5 has a longitudinal side concave 5c constituting the flexible support socket and one side longitudinal opposite convex 5d constituting the support point rigid.

Selon la variante de réalisation représentée sur la figure 5, les moyens de répartition de la pression de la sangle 3 sur l'élément de rembourrage interne 6 sont formés par des matériaux de densité différente le constituant, le matériau correspondant à une zone centrale 13 étant de densité plus faible que la densité du matériau correspondant à deux zones latérales adjacentes 14, 15 de manière à constituer une zone centrale 13 apte à l'écrasement de façon à absorber le tendon du gros orteil.According to the variant shown on the Figure 5, the means of distributing the pressure of the strap 3 on the internal padding element 6 are formed by materials of different density the constituent, the material corresponding to a central zone 13 being of higher density lower than the density of the material corresponding to two areas adjacent sides 14, 15 so as to constitute a zone central 13 capable of being crushed so as to absorb the tendon of the big toe.

Selon la variante des figures 6 et 7, l'une des sangles crantées du mode précédent est remplacé par une partie de sangle 33 comprenant une série de trous 330 orientés dans la direction de la longueur de ladite partie de sangle. L'élément de support 5 comprend, quant à lui, à son extrémité 5a, un trou épaulé 500 entre deux pions 501, 502 formant des moyens qui s'engagent dans les trous 330 de la partie de sangle. Un moyen de fixation amovible du type vis/écrou passant au travers du trou 500 et de l'un de ceux 300 de la partie de sangle réalise la liaison de la partie de sangle avec l'élément 5. Les pions 501, 502 prennnent position dans deux trous de la partie de sangles, adjacents au trou de fixation. Malgré un réglage moins rapide, un tel système a pour avantage d'immobiliser l'élément de support en rotation par rapport à la partie de sangle et permet une reprise d'efforts importants répartis sur trois éléments séparés. Le moyen de fixation vis/écrou pourrait être remplacé par un moyen de clipsage afin de faciliter le réglage, par exemple.According to the variant of Figures 6 and 7, one of the straps notched from the previous mode is replaced by a part of strap 33 comprising a series of holes 330 oriented in the direction of the length of said strap portion. The support element 5 comprises, for its part, at its end 5a, a shouldered hole 500 between two pins 501, 502 forming means which engage in the holes 330 of the strap part. A fixing means removable screw / nut type passing through hole 500 and one of those 300 of the strap part realizes the connection of the part of strap with element 5. Pawns 501, 502 take hold position in two holes in the strap part, adjacent to the fixing hole. Despite a slower adjustment, such a system has the advantage of immobilizing the rotating support element relative to the strap part and allows recovery significant efforts spread over three separate elements. The screw / nut fixing means could be replaced by a means for easy adjustment, for example.

Bien entendu l'invention ne se limite pas seulement aux seuls exemples de réalisation décrits à titre d'exemple mais s'étend aussi à tout mode équivalent qui se trouvent couverts par les revendications qui suivent.Of course, the invention is not limited only to only exemplary embodiments described by way of example but also extends to any equivalent mode that is covered by the claims which follow.
