Abstract

This fastener for closing two opposed closure flaps of a sports footwear, notably a ski boot, comprises on a first flap of the footwear a coupling member adapted to interconnect these flaps, means for anchoring one end of the coupling member to a catch member secured to the one flap, a binding lever pivoted to a support fixed to the other flap of the footwear and having pivoted thereto the other end of the coupling member and comprising beyond its pivot point a rigid extension lying substantially within the plane and thickness of the binding lever extension for interlocking substantially in a common plane the end of the lever extension and the binding lever in their closed and fold-down position which is also the closed position of the fastener itself. The end of the extension is notched and has pivotally mounted therein a spring-loaded pawl formed with teeth cooperating with corresponding teeth formed in the bottom of this notch on the binding lever, so that when closed the device can be opened by actuating a small auxiliary lever or depressing an arm with the thumb.

Description

La présente invention a pour objet un dispositif de fermeture de deux parties d'une chaussure de sport comprenant un organe de liaison, de préférence non extensible, destiné à relier les deux parties de la chaussure, des moyens de solidarisation d'une première extrémité de cet organe de liaison à un élément de fixation destiné à être fixé à l'une des parties de la chaussure, un levier tendeur articulé sur un support destiné à être fixé à l'autre partie de la chaussure et sur lequel est articulée la deuxième extrémité dudit organe de liaison, et dans lequel ledit organe de liaison présente, du côté de l'autre partie, un prolongement rigide au-delà de son point d'articulation avec le levier tendeur, ledit prolongement s'étendant sensiblement dans le plan et l'épaisseur du levier tendeur en position fermée, rabattue, du levier tendeur.The present invention relates to a device for closing two parts of a sports shoe comprising a connecting member, preferably not extensible, intended to connect the two parts of the shoe, means for securing a first end of this connecting member to a fastening element intended to be fixed to one of the parts of the shoe, a tensioning lever articulated on a support intended to be fixed to the other part of the shoe and on which the second end is articulated of said connecting member, and in which said connecting member has, on the side of the other part, a rigid extension beyond its point of articulation with the tensioning lever, said extension extending substantially in the plane and l thickness of the tensioning lever in the closed, folded position of the tensioning lever.

Les dispositifs utilisés à ce jour pour fermer les chaussures de ski, appelés communément boucles, sont soumis à une forte tension. Pour être maintenu de façon sûre en position fermée, le levier tendeur de ces boucles doit être soumis à une force de traction dont le support s'écarte nettement du point d'articulation de la boucle sur la chaussure. Une réalisation récente d'une telle boucle est décrite dans les documents US-A-4 051 611 et EP-A-0 047 024. De manière à assurer les conditions de fermeture rappelées ci-dessus, le point d'articulation du levier tendeur sur la chaussure doit être relativement haut, particulièrement lorsque les deux parties de la chaussure à relier ne présentent ensemble qù'une faible courbure. Il existe en outre des positions de montage de ces boucles sur une certaine chaussure, dans lesquelles la forme de la chaussure est si plate qu'il est difficile de maintenir la boucle fermée sans surélever de façon inacceptable le point d'articulation du levier tendeur relativement à la chaussure. D'une manière générale, les boucles réalisées selon un principe actuel, doivent être relativement hautes, de sorte qu'elles forment une saillie plus ou moins importante sur la chaussure. Une telle saillie présente plusieurs inconvénients. Notamment, lorsque la chauss- sure de ski est utilisée pour une course de vitesse, cette saillie nuit à l'aérodynamisme la chaussure. Dans d'autres cas, elle risque de s'accrocher aux perches marquant le parcours de la course. Lors de la marche ou en cas de chute, la boucle peut facilement s'accrocher à un obstacle et être endommagée. Il convient en outre de souligner l'importance de l'esthétique dans le cas d'une chaussure de ski.The devices used to date to close ski boots, commonly called buckles, are subjected to high tension. To be held securely in the closed position, the tensioning lever of these buckles must be subjected to a tensile force whose support clearly deviates from the point of articulation of the buckle on the shoe. A recent embodiment of such a loop is described in documents US-A-4,051,611 and EP-A-0 047 024. In order to ensure the closing conditions mentioned above, the point of articulation of the tensioning lever on the shoe must be relatively high, particularly when the two parts of the shoe to be joined together have only a slight curvature. There are also mounting positions of these buckles on a certain shoe, in which the shape of the shoe is so flat that it is difficult to keep the buckle closed without unacceptably raising the articulation point of the tensioning lever relatively to the shoe. In general, the loops produced according to a current principle, must be relatively high, so that they form a more or less significant projection on the shoe. Such a projection has several drawbacks. In particular, when the ski boot is used for a speed race, this projection harms the aerodynamics of the boot. In other cases, it risks catching on the poles marking the course of the race. When walking or falling, the buckle can easily catch on an obstacle and be damaged. It is also worth emphasizing the importance of aesthetics in the case of a ski boot.

Une solution à été proposée pour maintenir une boucle en position de fermeture, dans le modèle d'utilité DE-U-8 002 933. Dans cette exécution, le levier tendeur, muni d'une rangée de crans pour l'accrochage de la boucle, présente à son extrémité un petit crochet destiné à s'accrocher dans un cran du support du levier tendeur. Toutefois, pour que ce crochet auxiliaire soit efficace, la partie de la chaussure sur laquelle est monté le support du levier tendeur doit présenter une courbure déterminée. Il est donc nécessaire de fabriquer une boucle particulière adaptée a chaque courbure de chaussure, ce qui n'est évidemment pas rationnel. En outre, un tel crochet auxiliaire forme une saillie très marquée sur la chaussure.A solution has been proposed to maintain a loop in the closed position, in the utility model DE-U-8 002 933. In this embodiment, the tensioning lever, provided with a row of notches for hooking the loop , has at its end a small hook intended to hang in a notch of the support of the tensioning lever. However, for this auxiliary hook to be effective, the part of the shoe on which the support of the tensioning lever is mounted must have a determined curvature. It is therefore necessary to manufacture a particular loop adapted to each shoe curvature, which is obviously not rational. In addition, such an auxiliary hook forms a very marked projection on the shoe.

Dans une autre exécution (FR-A-1 366 146) le levier tendeur vient se verrouiller dans deux crans de son support, en position de fermeture, un levier auxiliaire, monté coaxialement au levier tendeur, permettant de déverrouiller le levier tendeur en le dégageant de ses crans. Le déverrouillage exige une déformation élastique et le levier auxiliaire fait saillie au-dessus du levier tendeur. En outre, la position de verrouillage est étroitement liée à la position du levier tendeur en position de fermeture, c'est-à-dire à la courbure de la chaussure.In another embodiment (FR-A-1 366 146) the tensioning lever is locked in two notches of its support, in the closed position, an auxiliary lever, mounted coaxially with the tensioning lever, making it possible to unlock the tensioning lever by releasing it of his notches. Unlocking requires elastic deformation and the auxiliary lever protrudes above the tensioning lever. In addition, the locking position is closely linked to the position of the tensioning lever in the closed position, that is to say to the curvature of the shoe.

Dans une autre exécution (DE-A-1 685 813) l'extrémité du levier tendeur vient s'accrocher sous un crochet en déformant élastiquement celui-ci. Ce dispositif de retenue ne constitue pas un verrouillage sûr en raison même de l'élasticité du crochet. La libération du levier tendeur exige en outre une force d'autant plus élevée que la résistance du crochet à la déformation est élevée.In another embodiment (DE-A-1 685 813) the end of the tensioning lever is hooked under a hook by elastically deforming the latter. This retainer is not a secure lock due to the elasticity of the hook. The release of the tensioning lever also requires a higher force the higher the resistance of the hook to deformation.

La présente invention offre un dispositif de fermeture de deux parties d'une chaussure de sport obviant aux inconvénients des dispositifs susmentionnés. Le dispositif selon l'invention telle que revendiquée est maintenu fermé sons égard au principe du non alignement des points d'articulation et d'accrochage. Le dispositif de fermeture est particulièrement plat, de faible hauteur. Il est capable de s'adapter automatiquement aux différentes courbures de chaussures rencontrées. En outre, il peut être monté sur des parties particulièrement plates de la chaussure. En pratique, le principe du non alignement de points d'articulation sera toujours respecté, mais ce non alignement peut être très faible.The present invention provides a device for closing two parts of a sports shoe overcoming the drawbacks of the above-mentioned devices. The device according to the invention as claimed is kept closed without regard to the principle of non-alignment of the points of articulation and attachment. The closing device is particularly flat, of low height. It is capable of automatically adapting to the different curvatures of shoes encountered. In addition, it can be mounted on particularly flat parts of the shoe. In practice, the principle of non-alignment of points of articulation will always be respected, but this non-alignment can be very weak.

Selon une forme d'exécution de l'invention, les moyens de verrouillage sont constitués par un cliquet monté à l'extrémité du levier tendeur et coopérant avec une denture frontale prévue à l'extrémité du prolongement de l'organe de liaison. Ce cliquet peut être libéré par un petit levier auxiliaire ou par un bras sur lequel il est possible de presser avec le pouce.According to one embodiment of the invention, the locking means consist of a pawl mounted at the end of the tensioning lever and cooperating with a front toothing provided at the end of the extension of the connecting member. This pawl can be released by a small auxiliary lever or by an arm on which it is possible to press with the thumb.

Selon une autre forme d'exécution, les moyens de verrouillage sont constitués par une barrette transversale coulissant dans le levier tendeur et venant s'engager dans une encoche pratiquée dans l'extrémité du prolongement de l'organe de liaison.According to another embodiment, the locking means consist of a transverse bar sliding in the tensioning lever and coming to engage in a notch formed in the end of the extension of the connecting member.

On voit que la caractéristique essentielle de l'invention consiste à verrouiller ensemble le levier tendeur et l'organe de liaison qui peut être soit une boucle, soit une barrette minie de crochets destinés à recevoir une boucle attachée à l'autre partie de la chaussure. D'une manière générale, l'organe de liaison peut être quelconque, simple ou complexe, réglable ou non. Quant au levier tendeur, il peut présenter deux bras entre lesquels est articulé l'organe de liaison ou, inversement, présenter un seul bras s'engageant dans l'extrémité en forme de fourche de l'organe de liaison. Ceci pour montrer que d'innombrables variantes d'exécution sont possibles en ce qui concerne l'organe de liaison, le point d'accrochage et la forme du levier tendeur.It can be seen that the essential characteristic of the invention consists in locking together the tensioning lever and the connecting member which can be either a loop or a mini bar of hooks intended to receive a loop attached to the other part of the shoe. In general, the connecting member can be any, simple or complex, adjustable or not. As for the tensioning lever, it may have two arms between which the link member is articulated or, conversely, have a single arm engaging in the fork-shaped end of the link member. This is to show that countless variants are possible with regard to the connecting member, the attachment point and the shape of the tensioning lever.

On se réfère aux figures 1 à 4. Le dispositif de fermeture comprend un levier tendeur 1 constitué d'une plaquette très légèrement recourbée et fendue de manière à présenter deux bras 1 a et 1 b articulés respectivement sur deux oreilles 2 et 3 d'un support 4 constitué par une plaquette métallique aux deux bords 2 et 3 coudés à l'équerre, fixée sur l'un des rabats 5 de la chaussure représentée en coupe par au moins un rivet 6. Le levier tendeur 1 est articulé sur les oreilles 2 et 3 au moyen de deux axes rivetés 7 et 8. Sur le levier tendeur, entre ses bras 1 a et 1 b, est articulée une barrette de traction 9 autour d'un axe 10 rivé sur le levier tendeur. La barrette 9 est munie d'une tige filetée 11 sur laquelle est vissée une plaquette intermédiaire 12 sur laquelle est articulée une boucle rectangulaire 13 qui vient s'accrocher dans l'une des dents 14 d'une crémaillère 15 fixée par un rivet 16 sur l'autre rabat 17 de la chaussure. Toutes les pièces du dispositif de fermeture sont en métal. La barrette de traction 9 présente un prolongement 9a au-delà de son axe d'articulation 10, prolongement qui s'étend entre les deux bras 1a et 1b, parallèlement au levier tendeur 1 et dans l'épaisseur de celui-ci, dans la position fermée rabattue représentée aux figures 1 à 3. Autour de l'axe 10 est monté un ressort en cor de chasse 18 dont les bras coudés s'appuient respectivement sur le prolongement 9a et sur le levier tendeur 1 et qui a tendance à maintenir le levier tendeur 1 et la barrette 9 dans la position rabattue représentée aux figures 2 et 3. L'extrémité frontale du prolongement 9a est munie d'une denture horizontale 19. En face de cette denture, dans un dégagement 20 du levier tendeur 1, est monté un cliquet 21 autour d'un axe 22. Ce cliquet a la même largeur que la barrette 9. Autour de l'axe 22 est monté un ressort de torsion en cor de chasse 23 qui a tendance à maintenir le bec du cliquet 21 engagé dans la denture 19. Le cliquet 21 présente un bras 21 a s'étendant sous l'extrémité du levier tandeur 1, dans un dégagement de celui-ci. A l'extrémité du levier tendeur 1 est articulé un petit levier auxiliaire 24 autour d'un axe 25. Ce levier auxiliaire 24 présente un doigt 24a s'engageant entre le bras 21 a du cliquet 21 et le levier tendeur 1. Il a donc tendance à être maintenu dans la position représentée au dessin par le ressort de cliquet 23. Le levier auxiliaire 24 est muni de rainures 26 facilitant son actionnement en empêchant le glissement du doigt de l'utilisateur, respectivement de son gant.Referring to Figures 1 to 4. The closure device comprises a tensioning lever 1 consisting of a plate very slightly bent and split so as to have two arms 1 a and 1 b articulated respectively on two ears 2 and 3 of a support 4 constituted by a metal plate with two edges 2 and 3 bent at right angles, fixed on one of the flaps 5 of the shoe shown in section by at least one rivet 6. The tensioning lever 1 is articulated on the ears 2 and 3 by means of two riveted axes 7 and 8. On the tensioning lever, between its arms 1a and 1b, is articulated a pull bar 9 about an axis 10 riveted on the tensioning lever. The bar 9 is provided with a threaded rod 11 on which is screwed an intermediate plate 12 on which is articulated a rectangular loop 13 which comes to hang in one of the teeth 14 of a rack 15 fixed by a rivet 16 on the other flap 17 of the shoe. All parts of the closing device are made of metal. The pull bar 9 has an extension 9a beyond its articulation axis 10, an extension which extends between the two arms 1a and 1b, parallel to the tensioning lever 1 and in the thickness of the latter, in the closed folded position shown in Figures 1 to 3. Around the axis 10 is mounted a spring horn 18 whose bent arms are respectively supported by the extension 9a and the tensioning lever 1 and which tends to maintain the tensioning lever 1 and the bar 9 in the folded position shown in Figures 2 and 3. The front end of the extension 9a is provided with a horizontal toothing 19. Opposite this toothing, in a clearance 20 of the tensioning lever 1, is mounted a pawl 21 around an axis 22. This pawl has the same width as the bar 9. Around the axis 22 is mounted a hunting horn torsion spring 23 which tends to keep the spout of the pawl 21 engaged in the toothing 19. The pawl 21 has an arm 21 a extending under the 'end of the tandering lever 1, in a clearance thereof. At the end of the tensioning lever 1 is articulated a small auxiliary lever 24 about an axis 25. This auxiliary lever 24 has a finger 24a engaging between the arm 21 a of the pawl 21 and the tensioning lever 1. It therefore has tendency to be maintained in the position shown in the drawing by the pawl spring 23. The auxiliary lever 24 is provided with grooves 26 facilitating its actuation by preventing the sliding of the user's finger, respectively of his glove.

Le fonctionnement du dispositif décrit est le suivant: dans la position représentée aux figures 2 et 3, le bec du cliquet 21 est engagé dans l'une des dents de la denture 19. Tout effort ayant tendance à soulever le levier tendeur dans le sens de la flèche F1, par exemple une composante de la force de traction sur la barrette 9 à la suite d'une déformation élastique de la chaussure ayant pour effet d'amener momentanément le point d'articulation 10 au-dessus de la droite reliant le point d'accrochage de la boucle 13 à la crémaillière 14 à l'axe d'articulation 8, a tendance à engager davantage le cliquet 21 dans la denture 19. Le cliquet ne pouvant pas tourner, la barrette 9 et le levier tendeur 1 sont bloqués ou verrouillés dans la position représentée. Pour ouvrir le dispositif de fermeture, l'utilisateur introduit l'extrémité d'un doigt sous le levier 24 et soulève celui-ci. Le ressort 23 étant relativement faible, l'actionnement du levier 24 ne demande qu'un faible effort. Le basculement du levier auxiliaire 24 dans le sens de la flèche F2 (fig. 3) a pour effet de faire pivoter le cliquet 21 dans le sens de la flèche F4. Ce cliquet 21 s'écarte alors de la denture 19 pour venir buter contre la paroi supérieure de son logement 20, en libérant la barrette 9. L'utilisateur peut alors relever le levier tendeur 1 dans la position ouverte représentée à la figure 4. La boucle 13 se décroche alors de manieère connue.The operation of the device described is as follows: in the position shown in Figures 2 and 3, the pawl of the pawl 21 is engaged in one of the teeth of the toothing 19. Any effort tending to raise the tensioning lever in the direction of arrow F1, for example a component of the tensile force on the bar 9 following an elastic deformation of the shoe having the effect of temporarily bringing the point of articulation 10 above the straight line connecting the point for attaching the loop 13 to the rack 14 to the hinge pin 8, tends to further engage the pawl 21 in the toothing 19. The pawl cannot rotate, the bar 9 and the tensioning lever 1 are blocked or locked in the position shown. To open the closing device, the user introduces the end of a finger under the lever 24 and lifts the latter. The spring 23 being relatively weak, the actuation of the lever 24 requires only a small effort. The tilting of the auxiliary lever 24 in the direction of arrow F2 (fig. 3) has the effect of pivoting the pawl 21 in the direction of arrow F4. This pawl 21 then departs from the toothing 19 to abut against the upper wall of its housing 20, by releasing the bar 9. The user can then raise the tensioning lever 1 in the open position shown in FIG. 4. loop 13 is then released in a known manner.

Pour fermer le dispositif, l'utilisateur, après avoir engagé la boucle 13 dans la crémaillère 15, rabat le levier tendeur 1 sur la chaussure. Lors de ce rabattement, le cliquet 21 vient glisser sur les dents de la denture 19, puis s'engage dans l'une des dents, verrouillant à nouveau ensemble le levier tendeur 1 et la barrette 9. Il convient de noter que le levier tendeur 1 peut toujours être rabattu complètement et que le cliquet 21 vient automatiquement occuper une position de verrouillage adéquate.To close the device, the user, after engaging the loop 13 in the rack 15, folds the tensioning lever 1 on the shoe. During this folding, the pawl 21 comes to slide on the teeth of the toothing 19, then engages in one of the teeth, again locking together the tensioning lever 1 and the bar 9. It should be noted that the tensioning lever 1 can still be folded down completely and the pawl 21 automatically occupies an adequate locking position.

Cette première forme d'exécution est susceptible de nombreuses variantes. L'une de ces variantes est représentée partiellement à la figure 5, qui est une vue en coupe analogue à celle de la figure 3. Les éléments identiques à ceux de la première forme d'exécution sont désignés par les mêmes références. Dans cette exécution, la fente séparant les bras 1 a et 1 b du levier tendeur 1 est prolongée vers l'extrémité en une fente 27 dans laquelle est articulée un cliquet 28 autour d'un axe 29. Ce cliquet 28 présente un bras s'élargissant en forme de bouton poussoir rectangulaire 30 affleurant la face supérieure de l'extrémité coudée du levier tendeur 1. En-dessous de ce bouton poussoir 30 est ménagée une creusure permettant d'enfoncer le bouton poussoir 30 dans le levier tendeur 1. Le bec du cliquet 28 est lui-même dentelé avec une denture de forme conjuguée à la denture 19 de manière à répartir l'effort sur le bec de cliquet. Le cliquet 28 est maintenu élastiquement dans la position représentée soit au moyen d'un ressort en cor de chasse, non représenté, comme dans la première forme d'exécution, soit par un ressort héli- coidal 31 travaillant en compression entre le bouton poussoir 30 et le fond de la creusure 32. A la place du ressort 31 il serait possible de prévoir un simple morceau de caoutchouc élastique. Le fonctionnement de cette forme d'exécution est le même que celui de la première forme d'exécution, à la différence que l'utilisateur doit appuyer avec le pouce sur le poussoir 30 en même temps qu'il soulève le levier tendeur 1 par un ou deux doigts.This first embodiment is susceptible of numerous variants. One of these variants is partially shown in Figure 5, which is a sectional view similar to that of Figure 3. The elements identical to those of the first embodiment are designated by the same references. In this embodiment, the slot separating the arms 1a and 1b of the tensioning lever 1 is extended towards the end into a slot 27 in which a pawl 28 is articulated around an axis 29. This pawl 28 has an arm s' widening in the form of a rectangular push button 30 flush with the upper face of the bent end of the tensioning lever 1. Below this push button 30 is a recess enabling the push button 30 to be pushed into the tensioning lever 1. The spout of the pawl 28 is itself serrated with a toothing of shape conjugate to the toothing 19 so as to distribute the force on the pawl spout. The pawl 28 is held elastically in the position shown either by means of a hunting horn spring, not shown, as in the first embodiment, or by a helical spring 31 working in compression between the push button 30 and the bottom of the hollow 32. Instead of the spring 31, it would be possible to provide a simple piece of elastic rubber. The operation of this embodiment is the same as that of the first embodiment, with the difference that the user must press with the thumb on the pusher 30 at the same time as he raises the tensioning lever 1 by a or two fingers.

La figure 6 illustre une variante d'exécution dans laquelle le bouton poussoir 30 est remplacé par une extrémité élargie striée 33 s'étendant sensiblement parallèlement à un rebord coudé 34 du levier tendeur 1. Pour libérer et soulever le levier tendeur 1, l'utilisateur pince les parties 33 et 34 ensemble entre le doigt et le pouce.FIG. 6 illustrates an alternative embodiment in which the push button 30 is replaced by an enlarged ridged end 33 extending substantially parallel to a bent edge 34 of the tensioning lever 1. To release and raise the tensioning lever 1, the user clamp the parts 33 and 34 together between the finger and the thumb.

Une autre forme d'exécution du dispositif de verrouillage est utilisée dans la troisième forme d'exécution représentée partiellement aux figures 7 et 8. On n'a représenté ici que le levier tendeur et la barrette de traction. Les autres éléments sont identiques à ceux des formes d'exécution précédemment décrites. Le levier tendeur 11 présente également deux bras 1a' et 1b' articulés sur une plaquette 4' munie de deux oreilles 2' et 3' s'engageant dans deux fentes prévues à l'extrémité de chacun des bras 1 a' et 1 b', l'articulation étant assurée par deux goupilles 35 et 36 chassées dans chacun des bras. Une barrette de traction 9' est articulée sur le levier tendeur 1' autour d'un axe 10'. La barrette 9' présente un prolongement 9a' au-delà de son axe d'articulation 10'. L'extrémité de ce prolongement présente une face oblique 37 dans laquelle est ménagée une encoche horizontale 38. Dans cette encoche est engagée une barrette transversale 39 traversant le levier tendeur 1' de part en part à travers un perçage présentant un profil oblong 40 s'étendant parallèlement au levier tendeur et permettant à la barrette 39 de se déplacer d'une extrémité à l'autre de ce profil 40. Dans le prolongement du profil 40, est percé un trou borgne 41 dans le levier tendeur 1', dans lequel est logé un ressort 42 poussant la barrette 39 au fond de l'encoche 38. Les extrémités de la barrette 38 dépassent de part et d'autre du levier tendeur 1' et sont solidaires de deux plaquettes 43 et 44, de préférence striées, permettant à l'utilisateur de déplacer la barrette 39 dans le sens de la flèche pour la dégager de l'encoche 38, pour permettre de relever le levier tendeur 1'. Lors de la fermeture du dispositif, la barrette 39 vient glisser sur la rampe 37 en comprimant le ressort 42, puis retombe automatiquement dans la position verrouillée représentée au dessin.Another embodiment of the locking device is used in the third embodiment partially shown in Figures 7 and 8. We have shown here that the tensioning lever and the pull bar. The other elements are identical to those of the embodiments previously described. The tensioning lever 11 also has two arms 1a 'and 1b' articulated on a plate 4 'provided with two ears 2' and 3 'engaging in two slots provided at the end of each of the arms 1a' and 1b ' , the articulation being ensured by two pins 35 and 36 driven into each of the arms. A pull bar 9 'is articulated on the tensioning lever 1' around an axis 10 '. The bar 9 'has an extension 9a' beyond its hinge axis 10 '. The end of this extension has an oblique face 37 in which is formed a horizontal notch 38. In this notch is engaged a transverse bar 39 passing through the tensioning lever 1 'right through through a bore having an oblong profile 40 s' extending parallel to the tensioning lever and allowing the bar 39 to move from one end to the other of this profile 40. In the extension of the profile 40, is drilled a blind hole 41 in the tensioning lever 1 ', in which is housed a spring 42 pushing the bar 39 at the bottom of the notch 38. The ends of the bar 38 protrude on either side of the tensioning lever 1 'and are integral with two plates 43 and 44, preferably ridged, allowing the user to move the bar 39 in the direction of the arrow to disengage it from the notch 38, to allow the tensioning lever 1 'to be raised. When the device is closed, the bar 39 slides on the ramp 37 by compressing the spring 42, then automatically drops back into the locked position shown in the drawing.

Il convient de souligner que le perfectionnement concerne uniquement le verrouillage en position fermée du levier tendeur et de la barrette de traction. En plus des nombreuses variantes possibles du dispositif de verrouillage, l'invention s'étend donc à toutes formes d'exécution du levier tendeur et de l'organe de traction articulé sur ce levier tendeur. Cet élément de traction peut notamment être en une ou plusieurs pièces; il peut porter une boucle, comme représenté, ou une crémaillère à laquelle vient s'accrocher une bouche articulée sur l'autre partie de la chaussure.It should be emphasized that the improvement relates only to the locking in the closed position of the tensioning lever and of the pull bar. In addition to the many possible variants of the locking device, the invention therefore extends to all forms of execution of the tensioning lever and of the traction member articulated on this tensioning lever. This traction element can in particular be in one or more parts; it can wear a buckle, as shown, or a rack to which comes to hang an articulated mouth on the other part of the shoe.

D'autre part, le levier tendeur ne doit pas obligatoirement avoir deux bras; l'organe de liaison pourrait lui-même présenter une extrémité en forme de fourche entre laquelle serait articulé le levier tendeur. Dans une telle forme d'exécution, le verrouillage pourrait être exécuté comme dans la troisième forme d'exécution selon les figures 7 et 8.On the other hand, the tensioning lever does not necessarily have to have two arms; the connecting member could itself have a fork-shaped end between which would be articulated the tensioning lever. In such an embodiment, the locking could be performed as in the third embodiment according to FIGS. 7 and 8.
