Description

L'invention se rapporte à un perfectionnement des boucles de fermeture de chaussures de sport et, plus particulièrement, de chaussures de ski alpin, de ski de fond, de ski de randonnée ou encore de snowboard.The invention relates to an improvement of the closing buckles of sports shoes and, more particularly, of alpine ski boots, cross-country skiing, ski touring or even snowboarding.

Plus précisément, l'invention concerne un perfectionnement des boucles de fermeture d'une chaussure de ski alpin destinée plus particulièrement à la compétition.More specifically, the invention relates to an improvement of the closing loops of an alpine ski boot intended more particularly for competition.

EXPOSÉ DE L'INVENTIONSTATEMENT OF THE INVENTION

Les chaussures de ski alpin comprennent généralement une coque externe rigide formée d'un collier en regard du mollet de l'utilisateur, articulé sur un bas de coque enveloppant la partie basse de la jambe et le pied de l'utilisateur, et pourvue d'un système de fermeture manuel à boucles de serrage et crochets.The alpine ski boots generally comprise a rigid outer shell formed of a collar facing the calf of the user, articulated on a lower shell enveloping the lower leg and the foot of the user, and provided with a manual closure system with clamping loops and hooks.

Un tel système de fermeture est décrit, notamment, dans le EP 657 117 où les boucles comprennent un levier principal ou levier-tendeur articulé sur une embase et présentant une encoche longitudinale dans laquelle est monté un tirant relié à un crochet.Such a closure system is described, in particular, in the EP 657 117 wherein the loops comprise a main lever or lever-tensioner articulated on a base and having a longitudinal notch in which is mounted a tie connected to a hook.

Dans ce mode de réalisation destiné principalement aux chaussures de ski alpin, et notamment à la compétition, l'extrémité libre du levier-tendeur porte un levier auxiliaire dont l'axe longitudinal médian est décalé vers l'arrière de la boucle relativement à l'axe du levier-tendeur pour permettre une ouverture plus facile de la boucle. Cette configuration présente également un chanfrein destiné à prévenir les risques d'accrochage accidentel de la boucle, en particulier lors d'un contact avec des piquets de slalom ou encore les bâtons de ski.In this embodiment intended mainly for alpine ski boots, and especially for competition, the free end of the lever-lever carries an auxiliary lever whose median longitudinal axis is offset towards the rear of the buckle relative to the axis of the lever-tensioner to allow easier opening of the loop. This configuration also has a chamfer designed to prevent the risk of accidental snapping of the loop, especially when in contact with slalom stakes or ski poles.

Cependant, le levier auxiliaire s'étend sur toute la largeur du levier-tendeur en ménageant un espace intercalaire et son axe de pivotement est logé dans un conduit qui débouche directement sur le chanfrein et qui n'est donc pas protégé.However, the auxiliary lever extends over the entire width of the tensioning lever by providing a spacer and its pivot axis is housed in a conduit which opens directly to the chamfer and which is not protected.

En raison de cet espace situé dans la zone de liaison entre les deux leviers, il subsiste un risque d'accrochage avec les piquets, ou même avec le bâton, qui peuvent heurter la chaussure et la boucle dans un mouvement du bas vers le haut et il subsiste donc encore un risque d'ouverture intempestive de la boucle.Because of this space located in the connection zone between the two levers, there is a risk of snagging with the stakes, or even with the stick, which can hit the shoe and the buckle in a movement from the bottom to the top and there is therefore still a risk of inadvertent opening of the loop.

Le FR 2 317 890 décrit une chaussure dont la boucle de fermeture est protégée contre les chocs par un dispositif de protection du levier constitué par une saillie formant un rebord en forme de rampe réalisée sur l'avant de la coque et placée en avant des boucles formant bouclier pour dévier les piquets.The FR 2 317 890 discloses a shoe whose closure loop is protected against shocks by a protector of the lever constituted by a projection forming a ramp-shaped rim formed on the front of the shell and placed in front of shield loops to deflect the stakes.

Cependant, ce mode de réalisation nécessite de modifier le moule de fabrication de la coque et se révèle insuffisamment efficace.However, this embodiment requires modifying the mold for manufacturing the shell and is insufficiently effective.

Par ailleurs, le levier auxiliaire étant destiné à faciliter la préhension du levier-tendeur et l'ouverture de la boucle, il est, par sa structure même, d'autant plus sujet à des ouvertures intempestives car c'est l'organe du système de fermeture dont le mode d'ouverture nécessite les efforts les plus faibles. Il s'avère donc important de protéger le levier auxiliaire de toute interaction parasite avec des éléments environnants.Moreover, the auxiliary lever being intended to facilitate the gripping of the tensioning lever and the opening of the loop, it is, by its very structure, all the more subject to untimely openings because it is the organ system closure whose opening mode requires the weakest efforts. It is therefore important to protect the auxiliary lever from any parasitic interaction with surrounding elements.

L'invention vise à remédier à ces problèmes techniques en modifiant la structure de la boucle.The invention aims to remedy these technical problems by modifying the structure of the loop.

Ce but est atteint, selon l'invention, au moyen d'une boucle de fermeture pour chaussure de ski comprenant un levier principal articulé sur une embase et présentant une encoche longitudinale dans laquelle est monté un tirant relié à un crochet et dont l'extrémité porte un levier auxiliaire, caractérisée en ce que le levier principal comporte une patte de protection délimitant latéralement un logement pour la réception du levier auxiliaire.This object is achieved, according to the invention, by means of a ski boot closure loop comprising a main lever articulated on a base and having a longitudinal notch in which is mounted a tie rod connected to a hook and whose end carries an auxiliary lever, characterized in that the main lever comprises a protective lug delimiting laterally a housing for receiving the auxiliary lever.

Selon une caractéristique avantageuse, la patte est déportée au moins partiellement vers l'arrière de la boucle.According to an advantageous characteristic, the tab is offset at least partially towards the rear of the loop.

Selon une autre caractéristique, la patte s'étend sur le côté latéral du levier auxiliaire.According to another characteristic, the tab extends on the lateral side of the auxiliary lever.

Selon une première variante, les bords respectifs de la patte et du levier auxiliaire sont orientés parallèlement.According to a first variant, the respective edges of the tab and the auxiliary lever are oriented parallel.

De préférence, la patte est orientée selon un axe incliné avec un angle compris entre 0° et 90° par rapport à l'axe longitudinal du tirant.
Selon encore une autre caractéristique, le levier auxiliaire présente un axe de rotation non perpendiculaire à l'axe du tirant.Preferably, the tab is oriented along an inclined axis with an angle between 0 ° and 90 ° relative to the longitudinal axis of the tie rod.
According to yet another feature, the auxiliary lever has an axis of rotation not perpendicular to the axis of the tie rod.

Selon une autre caractéristique, la patte est en saillie et se raccorde au levier principal par un premier bord extérieur parallèle à l'axe du tirant et qui se prolonge vers son extrémité libre par un second bord extérieur parallèle à l'axe médian du levier auxiliaire.According to another characteristic, the tab is projecting and is connected to the main lever by a first outer edge parallel to the axis of the tie rod and which extends towards its free end by a second outer edge parallel to the central axis of the auxiliary lever .

Selon encore une autre caractéristique, le second bord extérieur se prolonge par un troisième bord extérieur délimitant une extrémité effilée d'axe qui ferme, vers l'avant de la boucle, le logement du levier auxiliaire en rejoignant son bord d'extrémité.According to yet another characteristic, the second outer edge is extended by a third outer edge delimiting a tapered end of axis which closes, towards the front of the loop, the housing of the auxiliary lever by joining its end edge.

Selon une variante spécifique, la face supérieure de la patte porte un chanfrein.According to a specific variant, the upper face of the tab carries a chamfer.

Dans ce cas, le chanfrein s'étend de façon continue sur la face supérieure de la patte et l'épaisseur de la patte est amincie en direction de son bord latéral extérieur.In this case, the chamfer extends continuously on the upper face of the tab and the thickness of the tab is thinned towards its outer lateral edge.

De préférence, la face supérieure de la patte chanfreinée affleure la face supérieure du levier auxiliaire.Preferably, the upper face of the chamfered flap is flush with the upper face of the auxiliary lever.

Selon une autre variante, la face inférieure du levier auxiliaire et la face inférieure de l'extrémité de ladite patte sont biseautées et s'étendent dans un même plan surélevé par rapport au plan de l'embase en vue de faciliter la prise manuelle.According to another variant, the lower face of the auxiliary lever and the lower face of the end of said tab are bevelled and extend in the same plane raised relative to the plane of the base to facilitate manual grip.

Selon encore une autre variante, l'axe de rotation du levier auxiliaire est lié à la patte de protection.According to yet another variant, the axis of rotation of the auxiliary lever is linked to the protective tab.

Un autre objet de l'invention est une chaussure de ski équipée de boucles telles que définies ci-dessus.Another object of the invention is a ski boot equipped with loops as defined above.

De préférence, la patte est orientée en direction de l'avant de la chaussure tandis que le levier auxiliaire est orienté vers l'arrière de la chaussure.Preferably, the tab is oriented towards the front of the shoe while the auxiliary lever is oriented towards the rear of the shoe.

Grâce à l'apport de l'invention, il n'est plus nécessaire de décaler l'axe du tirant pour permettre la création d'un chanfrein de protection de la boucle.Thanks to the contribution of the invention, it is no longer necessary to shift the axis of the tie rod to allow the creation of a chamfer protecting the loop.

En outre, le levier auxiliaire est efficacement protégé par la patte frontale du levier principal qui délimite un logement abritant aussi le palier de l'axe de pivotement.In addition, the auxiliary lever is effectively protected by the front lug of the main lever which delimits a housing also housing the bearing of the pivot axis.

Enfin, dans une utilisation de la chaussure en compétition, les risques d'accrochage avec les piquets sont écartés du fait que la boucle ne présente plus qu'une face chanfreinée unique et continue sur tout son bord frontal sans aucune aspérité.Finally, in a use of the shoe in competition, the risk of hooking with the stakes are discarded because the loop has only one single chamfered face and continues on its entire front edge without any roughness.

Dans la description qui va suivre, on considérera que l'avant de la boucle se situe du côté du tirant 3 et du crochet.In the following description, it will be considered that the front of the loop is on the side of the tie rod 3 and the hook.

L'embase 1 est destinée à être rivetée sur la face supérieure de la coque de la chaussure et son axe longitudinal qui est confondu avec l'axe X1 du levier principal 2 et du tirant 3 est généralement orienté transversalement sur la coque de la chaussure, comme illustré sur la figure 5.The base 1 is intended to be riveted on the upper face of the shell of the boot and its longitudinal axis which coincides with the axis X1 of the main lever 2 and the tie rod 3 is generally oriented transversely on the shell of the boot, as illustrated on the figure 5 .

Dans un premier mode de réalisation illustré par les figures 1 à 3, l'extrémité libre du levier-tendeur opposée au crochet, porte un levier auxiliaire 4 dont l'axe longitudinal médian Y1 est angulairement décalé relativement à l'axe longitudinal X1 du levier principal 2 qui est lui-même perpendiculaire à son axe de pivotement X2. Ce décalage est orienté vers l'arrière de la chaussure afin de ménager, en cas de collision avec un obstacle, un angle de fuite vers l'arrière. L'axe longitudinal médian Y1 du levier auxiliaire 4 ne traverse pas toute la largeur du levier principal 2, mais est localisé uniquement sur une partie de la largeur du levier principal 2 qui est situé vers l'arrière de la chaussure.In a first embodiment illustrated by the Figures 1 to 3 , the free end of the lever-tensioner opposite the hook, carries an auxiliary lever 4 whose median longitudinal axis Y1 is angularly offset relative to the longitudinal axis X1 of the main lever 2 which is itself perpendicular to its pivot axis X2. This offset is oriented towards the rear of the shoe to provide, in the event of collision with an obstacle, a rear angle of flight. The median longitudinal axis Y1 of the auxiliary lever 4 does not cross the entire width of the main lever 2, but is located only on part of the width of the main lever 2 which is located towards the rear of the shoe.

Cette disposition est motivée par l'objectif d'éviter les risques d'accrochage de la boucle avec les piquets du parcours de slalom, en particulier.This provision is motivated by the objective of avoiding the risk of snagging the loop with the stakes of the slalom course, in particular.

En effet, en compétition, les skieurs passent très près des piquets et leurs chaussures sont même souvent amenées à heurter les piquets. Ce risque est d'autant plus fréquent qu'avec la vitesse, le corps du skieur et ses chaussures se trouvent fortement inclinées et c'est donc la face supérieure de la chaussure où se trouvent les boucles de serrage qui est principalement exposée.Indeed, in competition, the skiers pass very close to the stakes and their shoes are even often brought to hit the stakes. This risk is even more frequent with the speed, the body of the skier and his shoes are heavily inclined and it is therefore the upper face of the shoe where the loops of clamping is mainly exposed.

Les boucles connues ont déjà cherché à réduire ce risque mais la configuration du levier auxiliaire et sa position ne sont pas optimales ne serait-ce qu'en raison de la présence, à l'avant de la boucle, de l'extrémité en saillie de l'axe Y2 de pivotement du levier auxiliaire.The known loops have already sought to reduce this risk but the configuration of the auxiliary lever and its position are not optimal if only because of the presence, at the front of the loop, the projecting end of the pivot axis Y2 of the auxiliary lever.

L'invention vise à perfectionner les boucles existantes en améliorant la protection du levier auxiliaire et en réduisant conjointement les risques d'accrochage.The invention aims to improve the existing loops by improving the protection of the auxiliary lever and jointly reducing the risk of snagging.

Les modifications susceptibles d'être apportées, selon l'invention, aux composants de la boucle, prises isolément ou en combinaison, vont être décrites de façon détaillée ci-après.The modifications that may be made, according to the invention, to the components of the loop, taken individually or in combination, will be described in detail hereinafter.

Selon l'invention, le levier principal 2 comporte un corps de levier et, du côté frontal, c'est à dire du côté le plus en avant de la chaussure, une patte 21 en saillie dans le prolongement du corps du levier, qui est positionné sur l'un des côtés latéraux du levier auxiliaire 4.According to the invention, the main lever 2 comprises a lever body and, on the frontal side, that is to say on the most forward side of the boot, a tab 21 projecting in the extension of the body of the lever, which is positioned on one of the lateral sides of the auxiliary lever 4.

La patte 21 se raccorde au corps du levier principal 2 par un premier bord extérieur 21a parallèle à l'axe X1 suivi de façon continue par un second bord extérieur 21b sensiblement parallèle à l'axe Z1. De préférence, la patte fait partie intégrante du levier principal 2 et se trouve dans le prolongement de ce dernier pour former une excroissance sur l'avant du levier principal.The tab 21 is connected to the body of the main lever 2 by a first outer edge 21a parallel to the axis X1 followed continuously by a second outer edge 21b substantially parallel to the axis Z1. Preferably, the tab is an integral part of the main lever 2 and is in the extension of the latter to form an outgrowth on the front of the main lever.

Dans les modes de réalisation illustrés, la patte 21 est monobloc avec le levier tendeur principal 2, mais cette patte 21 pourrait être une pièce auxiliaire fixée à l'extrémité du levier principal 2 ce qui permettrait, en particulier, d'utiliser un matériau différent de celui du levier principal 2.In the illustrated embodiments, the lug 21 is integral with the main tensioner lever 2, but this lug 21 could be an auxiliary part attached to the end of the main lever 2, which would make it possible, in particular, to use a different material from that of the main lever 2.

Le bord intermédiaire 21b se prolonge par un troisième bord extérieur 21c formant une extrémité plus étroite inclinée selon un axe Z2 fermant, vers l'avant de la boucle, le logement 24 du levier auxiliaire 4 en rejoignant son bord d'extrémité, comme illustré par les figures 2 et 3.The intermediate edge 21b is extended by a third outer edge 21c forming a narrower end inclined along a Z2 axis closing towards the front of the loop, the housing 24 of the auxiliary lever 4 by joining its end edge, as illustrated by the figures 2 and 3 .

La patte 21 présente un bord intérieur droit 21d fermant le logement 24 en regard du bord latéral 41 du levier auxiliaire 4. Les bords 21d et 41 sont orientés parallèlement et inclinés selon un axe Z1 avec un angle α compris entre 0° et 90° par rapport à l'axe longitudinal X1 du tirant 3, comme illustré par la figure 2.The tab 21 has a right inner edge 21d closing the housing 24 facing the lateral edge 41 of the auxiliary lever 4. The edges 21d and 41 are oriented parallel and inclined along an axis Z1 with an angle α of between 0 ° and 90 ° by relative to the longitudinal axis X1 of the tie rod 3, as illustrated by the figure 2 .

La patte 21 s'étend ainsi au-delà de l'extrémité du levier principal 2 en délimitant, vers l'arrière de la boucle, un logement 24 de réception du levier auxiliaire 4 qui est fermé vers l'avant et sur le côté latéral de la boucle par le bord 21d. Les bords 21b et 21c de la patte 21 protègent à la fois le bord frontal 41 du levier auxiliaire 4 et son mécanisme de pivotement.The tab 21 thus extends beyond the end of the main lever 2 by delimiting, towards the rear of the loop, a housing 24 for receiving the auxiliary lever 4 which is closed towards the front and on the lateral side of the loop by the edge 21d. The edges 21b and 21c of the tab 21 protect both the front edge 41 of the auxiliary lever 4 and its pivoting mechanism.

En effet, dans ce logement, se trouve le palier de pivotement 23 porté par l'extrémité du corps du levier principal 2 et qui reçoit le pivot 5 d'axe Y2 dont les extrémités sont engagées, de part et d'autre et de manière rotative, dans deux conduits 42, 43 ménagés dans le corps du levier auxiliaire 4.Indeed, in this housing, is the pivot bearing 23 carried by the end of the body of the main lever 2 and which receives the pivot 5 axis Y2 whose ends are engaged, on both sides and so rotating in two ducts 42, 43 formed in the body of the auxiliary lever 4.

Le pivot 5 est couplé par ailleurs avec un ressort hélicoïdal 6 disposé entre le palier 23 et l'un des conduits 42, 43 (figure 3).The pivot 5 is also coupled with a coil spring 6 disposed between the bearing 23 and one of the conduits 42, 43 ( figure 3 ).

Dans une variante, une des extrémités du pivot 5 sur l'axe Y2 du levier auxiliaire 4 peut être logée dans la patte 21. Ainsi le levier auxiliaire pourrait être directement articulé sur cette patte.In a variant, one of the ends of the pivot 5 on the axis Y2 of the auxiliary lever 4 can be housed in the lug 21. Thus the auxiliary lever could be directly articulated on this lug.

Ainsi, afin de garantir un meilleur maintien du levier auxiliaire 4, son axe de rotation Y2 est lié via le palier 23 au corps du levier principal 2 et, conjointement, pour assurer un guidage mécanique optimal, l'axe de rotation Y2 est aussi lié à la patte 21.Thus, in order to guarantee a better hold of the auxiliary lever 4, its axis of rotation Y2 is linked via the bearing 23 to the body of the main lever 2 and, together, to ensure optimum mechanical guidance, the axis of rotation Y2 is also linked. at the foot 21.

En outre, la face inférieure 211 du tronçon d'extrémité délimité par le bord effilé 21c de la patte 21 est biseautée, comme illustré par la figure 3. Cette disposition permet de placer la face 211 dans le même plan que celui de la face inférieure du levier auxiliaire 4 qui est légèrement surélevé par rapport au plan de l'embase 1 en vue de faciliter la prise manuelle du levier auxiliaire 4 et du levier principal 2.In addition, the lower face 211 of the end portion delimited by the tapered edge 21c of the tab 21 is beveled, as illustrated by the figure 3 . This arrangement makes it possible to place the face 211 in the same plane as that of the lower face of the auxiliary lever 4 which is slightly raised relative to the plane of the base 1 in order to facilitate the manual engagement of the auxiliary lever 4 and the main lever 2.

Par ailleurs, la patte 21 porte sur sa face supérieure 210 un chanfrein orienté de telle façon que l'épaisseur de la patte 21 diminue en s'écartant du bord latéral 41 du levier auxiliaire 4. Autrement dit, le bord extérieur de la patte 21 est aminci par rapport au bord intérieur 21d de la patte 21.Furthermore, the tab 21 carries on its upper face 210 a chamfer oriented so that the thickness of the tab 21 decreases away from the side edge 41 of the auxiliary lever 4. In other words, the outer edge of the tab 21 is thinned with respect to the inner edge 21d of the tab 21.

Le chanfrein qui est réalisé sur la face supérieure 210 de la patte 21 s'étend de façon continue du bord de raccordement 21a jusqu'au bord d'extrémité 21c.The chamfer which is made on the upper face 210 of the tab 21 extends continuously from the connecting edge 21a to the end edge 21c.

Son inclinaison est comprise entre 30° et 60° vers l'avant par rapport à la face supérieure du levier auxiliaire de telle sorte qu'en cas de contact d'un piquet avec la boucle, la patte 21 puisse assurer le guidage et l'échappement du piquet vers l'extérieur en favorisant son glissement, sans lui laisser de possibilité d'accrochage.Its inclination is between 30 ° and 60 ° forwardly relative to the upper face of the auxiliary lever so that in case of contact of a peg with the loop, the lug 21 can guide and escape the stake to the outside by promoting its sliding, without giving him the possibility of attachment.

Afin de parfaire la protection du levier auxiliaire 4 et de réduire encore les risques d'accrochage, il est prévu, selon l'invention, de réaliser la face supérieure chanfreinée 210 de la patte 21 de façon affleurante à la face supérieure du levier auxiliaire 4 et à celle du levier principal 2 au repos, comme illustré par la figure 1.In order to complete the protection of the auxiliary lever 4 and further reduce the risks of attachment, it is provided according to the invention to provide the chamfered upper face 210 of the lug 21 flush with the upper face of the auxiliary lever 4 and that of the main lever 2 at rest, as illustrated by the figure 1 .

Le chanfrein forme une rampe ou un plan incliné de sorte que lorsqu'un piquet de slalom vient heurter la boucle, il est guidé et glisse sur ce plan incliné en étant ainsi écarté de la boucle sans risque d'accrochage.The chamfer forms a ramp or an inclined plane so that when a slalom post hits the loop, it is guided and slides on the inclined plane and thus being removed from the loop without risk of snagging.

Au lieu d'un chanfrein, il est possible, selon des variantes de l'invention non représentées, de donner à la face supérieure de la patte toute autre forme susceptible d'assurer le guidage et le glissement d'un objet vennant en collision avec la boucle. On peut par exemple prévoir une épaisseur progressivement décroissante sous la forme d'un arrondi.Instead of a chamfer, it is possible, according to variants of the invention not shown, to give the upper face of the leg any other shape capable of guiding and sliding an object colliding with the loop. For example, a gradually decreasing thickness can be provided in the form of a rounding.

Par ailleurs, le chanfrein du levier tendeur peut également s'étendre au levier auxiliaire. Aussi, l'extrémité du levier auxiliaire est également partiellement chanfreinée. Avantageusement, la patte 21 présente une zone chanfreinée mais on ne sortira pas du cadre de l'invention si cette patte 21 est d'épaisseur constante ou même si elle présente une excroissance d'épaisseur supérieure à l'épaisseur du levier auxiliaire 4. En effet, ces différentes formes de patte 21 permettent de remplir l'objectif de l'invention qui est de protéger la boucle d'ouvertures accidentelles et intempestives.Furthermore, the chamfer of the tensioning lever can also extend to the auxiliary lever. Also, the end of the auxiliary lever is also partially chamfered. Advantageously, the lug 21 has a chamfered area but it will not depart from the scope of the invention if this lug 21 is of constant thickness or even if it has an outgrowth greater than the thickness of the auxiliary lever 4. In Indeed, these different forms of tab 21 can fulfill the purpose of the invention is to protect the loop from accidental and untimely openings.

Dans la variante de réalisation illustrée par la figure 4, le levier auxiliaire 4 est articulé sur un axe Y2 perpendiculaire à l'axe longitudinal du tirant X1, la patte 21 du levier tendeur principal 2 venant protéger latéralement ce levier auxiliaire 4.In the variant embodiment illustrated by the figure 4 the auxiliary lever 4 is articulated on an axis Y2 perpendicular to the longitudinal axis of the tie rod X1, the tab 21 of the main tensioning lever 2 coming to protect this auxiliary lever 4 laterally.

De préférence, la zone d'extrémité située à l'avant de la patte 21 est à bord arrondi pour éviter tout accrochage intempestif avec un objet extérieur.Preferably, the end zone located at the front of the tab 21 has a rounded edge to prevent inadvertent attachment with an external object.

La boucle selon l'invention est de préférence réalisée en métal, notamment en aluminium, mais pourrait être fabriquée avec des matières plastiques, éventuellement chargées de fibres.The loop according to the invention is preferably made of metal, in particular aluminum, but could be made of plastics, possibly loaded with fibers.

La boucle selon l'invention est destinée à être utilisée, à titre principal, sur une chaussure de sport de glisse et, notamment, une chaussure de ski telle que réprésentée sur la figure 5. Dans sa partie basse, la coque C de cette chaussure est pourvue ici d'un unique ensemble constitué d'une boucle, telle que décrite précédemment, associée à un crochet K qui coopère avec une dentière correspondante (non visible sur la figure 5) portée par le côté opposé de la coque et assurant le verrouillage et la retenue du crochet.The buckle according to the invention is intended to be used, principally, on a gliding sports shoe and, in particular, a ski boot as represented on the figure 5 . In its lower part, the shell C of this shoe is provided here with a single assembly consisting of a loop, as described above, associated with a hook K which cooperates with a corresponding dente (not visible on the figure 5 ) carried by the opposite side of the hull and ensuring the locking and retaining of the hook.

Généralement, la coque C est équipée de quatre ensembles de boucles, crochets et dentières, respectivement deux au niveau du collier de la chaussure et deux au niveau du bas de coque.Generally, the shell C is equipped with four sets of loops, hooks and dentières, respectively two at the collar of the shoe and two at the bottom of the hull.
