Description

L'invention concerne une chaussure de sport, comme une chaussure de ski, de randonnée ou encore d'alpinisme.The invention relates to a sports shoe, such as a ski boot, hiking or mountaineering.

De manière connue, une chaussure de sport comprend une partie basse, appelée bas de coque et une partie haute, appelée collier. Le bas de coque comporte une semelle, de laquelle sont issus deux flancs. Le bas de coque et le collier maintiennent respectivement le pied et le mollet de l'utilisateur. Le collier est articulé par rapport au bas de coque pour faciliter la marche mais il peut être immobilisé par rapport à celui-ci lors de l'activité sportive pour assurer le blocage des mouvements de la cheville de l'utilisateur.In known manner, a sports shoe comprises a lower part, called bottom shell and a high part, called necklace. The shell bottom has a sole, from which two sides come from. The bottom of the shell and the collar hold respectively the foot and the calf of the user. The collar is hinged to the bottom of the shell to facilitate walking but it can be immobilized relative to it during the sporting activity to ensure the locking of the movements of the ankle of the user.

Le bas de coque peut être rigide ou souple. Dans le cas d'un bas de coque souple, celui-ci peut être serré autour du pied de l'utilisateur au moyen d'un lacet. Les dispositifs à lacet sont simples à mettre en place, ils sont légers. Cependant lorsqu'ils comprennent des passants fermés, ils gênent l'introduction du pied par l'utilisateur car même non serrés ils obstruent partiellement l'ouverture de la chaussure. D'autre part, il est difficile de serrer un bas de coque rigide simplement avec un lacet. C'est pourquoi les chaussures à bas de coque rigide sont équipées de moyens de serrage complémentaires, tels que des crochets, des boucles ou encore des dispositifs à sangle crantée qui permettent d'augmenter la force de serrage. Dans ce cas, plusieurs dispositifs sont utilisés pour remplacer un seul lacet.The bottom of the shell can be rigid or flexible. In the case of a soft shell bottom, it can be tightened around the foot of the user by means of a lace. The lace devices are simple to put in place, they are light. However, when they include closed passersby, they interfere with the introduction of the foot by the user because even untied they partially obstruct the opening of the shoe. On the other hand, it is difficult to squeeze a rigid shell bottom simply with a lace. This is why the shoes with rigid shell bottom are equipped with additional clamping means, such as hooks, loops or notched belt devices that increase the clamping force. In this case, several devices are used to replace a single lace.

En randonnée, en escalade ou en ski, l'utilisateur peut être amené à effectuer des pas chassés, passer au travers de branches ou encore escalader en prenant appui sur un flanc interne ou externe de sa chaussure. Or, les moyens de serrage du bas de coque des chaussures actuelles sont disposés sur le côté du bas de coque, c'est-à-dire sur un flanc. Ainsi, les moyens de serrage sont susceptibles d'être dégradés, voire désactivés par les éléments extérieurs comme les cailloux ou les branches lors de l'activité sportive.In hiking, climbing or skiing, the user may be required to perform not hunted, pass through branches or climb by leaning on an internal or external side of his shoe. However, the clamping means of the shell bottom of the current shoes are disposed on the side of the shell bottom, that is to say on a sidewall. Thus, the clamping means are likely to be degraded or even disabled by external elements such as pebbles or branches during the sporting activity.

DE 102 39 927 A1 divulgue une chaussure de sport avec les caractéristiques du préambule de la revendication 1. DE 102 39 927 A1 discloses a sports shoe with the features of the preamble of claim 1.

C'est notamment à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant une chaussure de sport avec laquelle les moyens de serrage du bas de coque sont moins exposés aux éléments extérieurs comme les cailloux ou les branches. Le risque que les moyens de serrage se dégradent ou se désactivent pendant l'activité sportive est donc plus faible. L'objectif de l'invention est d'autre part un dispositif qui combine les avantages d'un serrage par simple lacet et ceux d'un serrage plus puissant utilisant plusieurs crochets.It is particularly to these drawbacks that the invention more particularly intends to remedy by proposing a sports shoe with which the clamping means of the shell bottom are less exposed to external elements such as pebbles or branches. The risk that the clamping means degrade or deactivate during the sporting activity is therefore lower. The object of the invention is, on the other hand, a device which combines the advantages of clamping by a single lace and those of a more powerful clamping using several hooks.

L'objectif de l'invention est également de proposer une chaussure dont les moyens de serrage sont simples à utiliser, plus légers que les dispositifs connus et qui lorsqu'ils ne sont pas serrés, ne gênent pas l'introduction du pied.The object of the invention is also to provide a shoe whose clamping means are simple to use, lighter than known devices and when they are not tight, do not interfere with the introduction of the foot.

A cet effet l'invention concerne une chaussure de sport avec les caractéristiques de la revendication 1, comprenant un bas de coque rigide de maintien du pied d'un utilisateur, comportant une semelle et deux flancs latéraux issus de la semelle, et des moyens de serrage du bas de coque autour du pied de l'utilisateur, comprenant un élément filiforme de serrage des flancs l'un en direction de l'autre, qui est serré par pivotement d'un levier. Conformément à l'invention, le levier est prévu pour être pivoté dans un cran d'une crémaillère, adaptée pour coiffer les deux flancs du bas de coque en configuration serrée et cintrer les flancs en direction de la semelle sous l'action de pivotement du levier.For this purpose the invention relates to a sports shoe with the features of claim 1, comprising a bottom of rigid shell for holding the foot of a user, comprising a sole and two lateral flanks. from the sole, and clamping means of the lower shell around the foot of the user, comprising a filamentary member for clamping the flanks towards each other, which is pivotally tightened by a lever. According to the invention, the lever is designed to be pivoted in a notch of a rack, adapted to cap the two sides of the shell bottom in a tight configuration and to bend the flanks in the direction of the sole under the pivoting action of the the sink.

Grâce à l'invention, la crémaillère est disposée sur le dessus du bas de coque en configuration serrée. La crémaillère et le levier de serrage sont donc moins exposés aux cailloux et aux branches pendant l'activité sportive. De plus, le lacet donne à la chaussure un style de montagne, apprécié des spécialistes. Le serrage du bas de coque s'effectue simplement par basculement du levier de serrage puisque cela implique, d'une part, le serrage du lacet et, d'autre part, le cintrage des deux flancs du bas de coque autour du pied de l'utilisateur.Thanks to the invention, the rack is disposed on top of the shell bottom in a tight configuration. The rack and the clamping lever are therefore less exposed to pebbles and branches during sports activities. In addition, the lace gives the shoe a mountain style, appreciated by specialists. The tightening of the shell bottom is effected simply by tilting the clamping lever since this implies, on the one hand, the tightening of the lace and, on the other hand, the bending of the two sides of the shell bottom around the foot of the shell. 'user.

Selon des aspects avantageux mais non obligatoires de l'invention, une telle chaussure de sport peut incorporer l'une ou l'autre des caractéristiques suivantes, prises dans toute combinaison techniquement admissible :

  • L'élément filiforme est un lacet, alors que le levier est enfilé sur le lacet.
  • Le levier comporte deux bras délimitant chacun un orifice traversant de passage du lacet.
  • La crémaillère comprend une languette rigide et une pièce crantée, qui est fixée sur la languette et qui comprend plusieurs crans de réception du levier.

  • La crémaillère est configurée pour cintrer les flancs du bas de coque de manière répartie autour du pied de l'utilisateur.
  • Le levier de serrage comporte un arbre de pivotement à l'intérieur d'un cran de la crémaillère.
  • La distance entre l'arbre de pivotement du levier et les orifices de passage du lacet est sensiblement égale à l'écartement entre deux crans de la crémaillère.
  • Lesdits deux crans de la crémaillère sont séparés l'un de l'autre par un cran vide.
  • Le levier est détaché du bas de coque.
According to advantageous but non-obligatory aspects of the invention, such a sports shoe may incorporate any one of the following features, taken in any technically permissible combination:
  • The filiform element is a lace, while the lever is threaded on the lace.
  • The lever comprises two arms each delimiting a through hole passing through the lace.
  • The rack comprises a rigid tongue and a notched piece, which is fixed on the tongue and which comprises several notches for receiving the lever.
  • The rigid tongue is articulated on one of the sides of the bottom of the hull.
  • The rack is configured to bend the flanks of the shell bottom in a distributed manner around the user's foot.
  • The clamping lever has a pivot shaft within a notch of the rack.
  • The distance between the pivot shaft of the lever and the lace passage holes is substantially equal to the distance between two notches of the rack.
  • Said two notches of the rack are separated from each other by an empty notch.
  • The lever is detached from the bottom of the hull.

L'invention et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre, d'un mode de réalisation d'une chaussure de sport conforme à son principe, donnée à titre d'exemple et faite en référence aux dessins dans lesquels :

Sur la figure 1 est représentée une chaussure de sport 1. La chaussure 1 est une chaussure d'alpinisme, qui est adaptée pour le pied gauche d'un utilisateur. Cette chaussure 1 peut être adaptée pour la randonnée ou le ski.On the figure 1 is represented a sport shoe 1. The shoe 1 is a mountaineering shoe, which is adapted for the left foot of a user. This shoe 1 can be adapted for hiking or skiing.

La chaussure 1 comprend une partie basse 2 de réception du pied de l'utilisateur, qui est prévue pour entourer le pied de ce dernier. Cette partie basse 2, appelée « bas de coque », maintient le pied de l'utilisateur pendant la marche ou le ski. La partie basse 2 est rigide, c'est-à-dire qu'elle est réalisée dans un matériau ayant un module d'élasticité supérieur à 500 MPa. En pratique, le bas de coque 2 peut être fabriqué en matière plastique. Le bas de coque 2 s'étend selon un axe longitudinal X2, qui s'étire entre le talon et les orteils du pied de l'utilisateur lorsque celui-ci a la chaussure 1 au pied. La partie supérieure du bas de coque 2 forme une ouverture de passage pour le pied de l'utilisateur. Un chausson souple 8, en mousse ou en tissu, est disposé à l'intérieur de la chaussure 1 pour le confort de l'utilisateur.The shoe 1 comprises a lower part 2 for receiving the foot of the user, which is provided to surround the foot of the latter. This lower part 2, called "bottom hull", keeps the foot of the user during walking or skiing. The lower part 2 is rigid, that is to say that it is made of a material having a modulus of elasticity greater than 500 MPa. In practice, the bottom shell 2 can be made of plastic. The bottom shell 2 extends along a longitudinal axis X2, which extends between the heel and the toes of the foot of the user when he has the shoe 1 to the foot. The upper part of the shell bottom 2 forms a passage opening for the foot of the user. A soft liner 8, foam or fabric, is disposed inside the shoe 1 for the comfort of the user.

Le bas de coque 2 comprend une semelle 6 et deux flancs 2a et 2b qui s'étendent globalement vers le haut à partir de la semelle 6. Les flancs 2a et 2b sont cintrés en direction de la semelle 6, c'est-à-dire qu'ils présentent une concavité tournée vers la semelle 6. Les flancs 2a et 2b définissent avec la semelle 6 une cavité de réception du pied de l'utilisateur. Le flanc 2a est un flanc interne, c'est-à-dire tourné vers la chaussure droite de l'utilisateur, alors que le flanc 2b est un flanc externe. Les flancs 2a et 2b sont séparés par un évidement supérieur E2, ils ne se chevauchent pas comme c'est le cas dans les chaussures dites à "overlap" ou chevauchement.The shell bottom 2 comprises a sole 6 and two sides 2a and 2b which extend generally upwards from the sole 6. The sidewalls 2a and 2b are bent in the direction of the sole 6, that is to say say that they have a concavity turned towards the sole 6. The flanks 2a and 2b define with the sole 6 a cavity for receiving the foot of the user. The flank 2a is an internal flank, that is to say turned towards the right shoe of the user, while the flank 2b is an outer flank. The flanks 2a and 2b are separated by an upper recess E2, they do not overlap as is the case in shoes called "overlap" or overlap.

La chaussure 1 comporte également une partie haute 4 de maintien du mollet de l'utilisateur, qui prolonge le bas de coque 2 et qui est prévue pour entourer le bas de jambe, c'est-à-dire le mollet de l'utilisateur. Cette partie haute, appelée « collier » est articulée sur le bas de coque 2, notamment autour d'un axe Y4 perpendiculaire à l'axe longitudinal X2 et parallèle à la semelle 6. L'articulation entre le collier 8 et le bas de coque 2 est en pratique bloquée pendant l'activité sportive au moyen d'un mécanisme de blocage non représenté, qui est disposé à l'arrière du collier 8. Ainsi, la cheville de l'utilisateur est maintenue pendant la marche ou le ski.The boot 1 also comprises a high part 4 for maintaining the calf of the user, which extends the bottom of the shell 2 and which is provided to surround the lower leg, that is to say the calf of the user. This upper part, called "collar" is hinged to the shell bottom 2, especially around an axis Y4 perpendicular to the longitudinal axis X2 and parallel to the sole 6. The articulation between the collar 8 and the bottom of the hull 2 is in practice blocked during the sporting activity by means of a not shown locking mechanism, which is arranged at the rear of the collar 8. Thus, the user's ankle is maintained during walking or skiing.

La chaussure 1 comprend des moyens M1 de serrage du collier 4 autour du mollet de l'utilisateur. Ces moyens M1 incluent un dispositif de serrage à crans 100 et une bande autogrippante 102.The shoe 1 comprises means M1 clamping the collar 4 around the calf of the user. These means M1 include a clamping device with notches 100 and a self-gripping band 102.

La chaussure 1 est aussi équipée de moyens M2 de serrage du bas de coque 2 autour du pied de l'utilisateur. Ces moyens de serrage M2 sont manipulables par l'utilisateur entre des configurations complètement desserrée représentées aux figures 2 et 3, une configuration intermédiaire représentée à la figure 4 et une configuration serrée représentée à la figure 5.The shoe 1 is also equipped with M2 clamping means of the bottom shell 2 around the foot of the user. These clamping means M2 are manipulable by the user between completely loose configurations represented at Figures 2 and 3 , an intermediate configuration represented at figure 4 and a tight configuration represented in the figure 5 .

Les moyens de serrage M2 incluent un élément filiforme qui, dans l'exemple, est un lacet 10 qui chemine sur les flancs 2a et 2b. Le lacet 10 est un cordon en tissu qui traverse des passants 12 fixés sur les flancs 2a et 2b du bas de coque 2. Dans l'exemple, les passants 12 sont vissés sur les flancs 2a et 2b mais ils peuvent être aussi soudés ou collés. Le serrage du lacet 10 permet de rapprocher les flancs 2a et 2b l'un de l'autre et de resserrer l'évidement supérieur E2.The clamping means M2 include a filiform element which, in the example, is a lace 10 which runs on the sidewalls 2a and 2b. The lace 10 is a cloth cord which passes through loops 12 fixed on the sides 2a and 2b of the bottom shell 2. In the example, the loops 12 are screwed on the sides 2a and 2b but they can also be welded or glued . The tightening of the lace 10 makes it possible to bring the flanks 2a and 2b closer to one another and to tighten the upper recess E2.

Les moyens de serrage M2 incluent également une crémaillère 17 et un levier de serrage 14. Dans les configurations serrée et intermédiaire, le levier 14 est engagé dans la crémaillère 17. Une configuration desserrée est propice à l'installation du pied de l'utilisateur dans la chaussure 1 puisque les moyens M2 ne s'opposent alors pas à la déformation élastique du bas de coque 2 pour le passage du pied de l'utilisateur.The clamping means M2 also include a rack 17 and a clamping lever 14. In the tight and intermediate configurations, the lever 14 is engaged in the rack 17. A loosened configuration is conducive to the installation of the user's foot in the shoe 1 since the means M2 do not then oppose the elastic deformation of the shell bottom 2 for the passage of the foot of the user.

La crémaillère 17 s'étend transversalement à l'axe X2 et comprend une pièce crantée en métal 16 de réception du levier 14 et une languette rigide 18, qui supporte la pièce crantée 16. La languette rigide 18 est bombée, avec une concavité tournée vers la semelle 6 lorsque les moyens de serrage M2 sont en configuration intermédiaire ou serrée, c'est-à-dire que son centre de courbure est disposé du côté de la semelle 6. La pièce crantée 16 peut être collée ou soudée sur la languette 18. Elle est pourvue de crans 160. La crémaillère 17 est articulée sur le flanc 2a du bas de coque 2 au moyen d'une charnière 20. Cette charnière 20 est fixée en dessous d'une extrémité proximale 18a de la languette 18 et comprend un crochet 200 prenant en chape un anneau triangulaire vissé au flanc 2a.The rack 17 extends transversely to the axis X2 and comprises a notched metal piece 16 for receiving the lever 14 and a rigid tongue 18, which supports the toothed piece 16. The rigid tongue 18 is curved, with a concavity turned towards the sole 6 when the clamping means M2 are in the intermediate configuration or tight, that is to say that its center of curvature is disposed on the side of the sole 6. The toothed piece 16 can be glued or welded to the tongue 18 It is provided with notches 160. The rack 17 is articulated on the side 2a of the shell bottom 2 by means of a hinge 20. This hinge 20 is fixed below a proximal end 18a of the tongue 18 and comprises a 200 hook taking a cleft ring triangular screwed to the flank 2a.

Le levier 14 comprend un arbre 140 d'articulation, qui est prévu pour être logé dans un cran 160 de la pièce crantée 16. Comme visible à la figure 3, le levier 14 comprend deux bras 142 qui délimitent deux orifices traversants 014 alignés l'un avec l'autre. L'arbre d'articulation 140 traverse aussi les bras 142 du levier 14 et est mobile en rotation autour de son axe. Les orifices 014 sont des orifices de passage du lacet 10. Le levier 14 est donc enfilé sur le lacet 10. Par conséquent, le serrage du lacet 10 s'effectue par pivotement du levier 14 dans un cran 160 de la crémaillère 17. Par ailleurs, le levier 14 est détaché du bas de coque 2 et est libre de coulisser le long du lacet 10.The lever 14 comprises a hinge shaft 140, which is intended to be housed in a notch 160 of the toothed part 16. As visible in FIG. figure 3 , the lever 14 comprises two arms 142 which define two through orifices 014 aligned with each other. The hinge shaft 140 also passes through the arms 142 of the lever 14 and is rotatable about its axis. The orifices 014 are passage holes of the lace 10. The lever 14 is thus threaded on the lace 10. Therefore, the tightening of the lace 10 is effected by pivoting the lever 14 in a notch 160 of the rack 17. Moreover, the lever 14 is detached from the shell bottom 2 and is free to slide along the lace 10.

Pour mettre sa chaussure, l'utilisateur commence par dégager la crémaillère 17 en la faisant basculer autour du bout d'arbre pris en chape par le crochet 200. Le lacet 10 est également desserré et l'utilisateur peut insérer son pied à l'intérieur de la chaussure 1 sans difficulté.To put his shoe on, the user starts by clearing the rack 17 by tilting it around the end of the tree caught by the hook 200. The lace 10 is also loosened and the user can insert his foot inside. of shoe 1 without difficulty.

Pour serrer le pied à l'intérieur du bas de coque 2, l'utilisateur rabat la crémaillère 17 en direction du flanc 2b, comme représenté par la flèche R1 à la figure 2. Ensuite, l'utilisateur tire le lacet 10 et emmène le levier 14 en direction de la pièce crantée 16, comme représenté par la flèche R2 à la figure 2. L'utilisateur engage l'arbre d'articulation 140 du levier 14 dans un cran 160 de la pièce crantée 16. Les moyens de serrage M2 se trouvent alors dans la configuration intermédiaire de la figure 4. Le serrage du pied de l'utilisateur à l'intérieur du bas de coque 2 est d'autant plus important que le cran dans lequel est engagé l'arbre 140 est proche du flanc 2a.To tighten the foot inside the shell bottom 2, the user folds the rack 17 towards the side 2b, as represented by the arrow R1 at the figure 2 . Then, the user pulls the lace 10 and takes the lever 14 towards the toothed piece 16, as shown by arrow R2 to the figure 2 . The user engages the articulation shaft 140 of the lever 14 in a notch 160 of the toothed part 16. The clamping means M2 are then in the intermediate configuration of the figure 4 . The tightening of the foot of the user inside the shell bottom 2 is all the more important that the notch in which is engaged the shaft 140 is close to the side 2a.

Puis, l'utilisateur bascule le levier 14 de sa gauche vers sa droite, c'est-à-dire en direction du flanc 2a. Le basculement du levier 14 est représenté à la figure 4 par une flèche R3. Les moyens de serrage M2 parviennent alors dans la configuration serrée de la figure 5. Le basculement du levier 14 entraine conjointement une tension T1 sur le lacet 10 et un effort de traction T2 de la crémaillère 17 vers le flanc 2b. La tension T1 s'appliquant sur le lacet 10 permet de serrer le lacet 10 et de rapprocher les flancs 2a et 2b l'un de l'autre. Le lacet 10 permet donc de serrer le pied de l'utilisateur dans le sens de la largeur.Then, the user switches the lever 14 from its left to its right, that is to say towards the side 2a. The tilting of the lever 14 is represented at figure 4 by an arrow R3. The clamping means M2 then arrive in the tight configuration of the figure 5 . The tilting of the lever 14 jointly causes a tension T1 on the lace 10 and a traction force T2 of the rack 17 towards the side 2b. The tension T1 applying to the lace 10 makes it possible to tighten the lace 10 and to bring the flanks 2a and 2b closer to one another. The lace 10 thus makes it possible to tighten the foot of the user in the direction of the width.

En configuration serrée, la crémaillère 17 coiffe, ou chevauche, les flancs 2a et 2b sous l'effort de traction T2 du levier 14. Autrement dit, la crémaillère 17 fait le pont entre les flancs 2a et 2b. En effet, la crémaillère 17, ou plus exactement la languette rigide 18, prend appui à la fois sur le flanc 2a, par l'intermédiaire de la charnière 20 et sur le flanc 2b par l'intermédiaire de l'extrémité distale 18b de la languette 18. D'autre part, la crémaillère enjambe et traverse l'évidement E2. La crémaillère 17 est donc disposée au centre et sur le dessus du bas de coque 2. Cela a pour avantage qu'elle est moins exposée aux branches et aux cailloux lors des phases d'escalade ou de passage entre des branches.In a tight configuration, the rack 17 caps, or overlaps, the flanks 2a and 2b under the pulling force T2 of the lever 14. In other words, the rack 17 bridges the flanks 2a and 2b. Indeed, the rack 17, or more exactly the rigid tongue 18, is supported both on the side 2a, through the hinge 20 and on the side 2b via the distal end 18b of the tongue 18. On the other hand, the rack spans and passes through the recess E2. The rack 17 is disposed in the center and on the top of the bottom shell 2. This has the advantage that it is less exposed to branches and pebbles during climbing or passage between branches.

L'effort de traction T2 sur la crémaillère 17 permet de cintrer les flancs 2a et 2b en direction de la semelle 6, ce qui a pour effet de comprimer le pied de l'utilisateur dans le sens de la hauteur. Plus précisément, c'est la languette rigide 18 qui cintre les flancs 2a et 2b du bas de coque 2. La languette 18 tire d'une part sur le flanc 2a et appuie d'autre part sur le flanc 2b. L'évidement E2 donne une certaine souplesse au bas de coque 2, ce qui permet de déformer élastiquement le bas de coque 2 sous l'action de pivotement du levier 14. F1 et F2 désignent les efforts de cintrage de la crémaillère 17, respectivement sur les flancs 2a et 2b. Les efforts de cintrage F1 et F2 sont dirigés vers la semelle 6, c'est-à-dire qu'ils permettent d'accentuer la courbure des flancs 2a et 2b. Les efforts de cintrage F1 et F2 sont équivalents, c'est-à-dire que la crémaillère 17 appuie de manière sensiblement équirépartie sur les flancs 2a et 2b du bas de coque 2. L'utilisateur n'a donc pas la sensation d'avoir un côté plus serré que l'autre.The pulling force T2 on the rack 17 makes it possible to bend the flanks 2a and 2b towards the sole 6, which has the effect of compressing the user's foot in the direction of the height. More precisely, it is the rigid tongue 18 which hems the sides 2a and 2b of the bottom shell 2. The tongue 18 pulls on the one hand on the side 2a and on the other hand supports the side 2b. The recess E2 gives a certain flexibility to the bottom shell 2, which allows to elastically deform the shell bottom 2 under the pivoting action of the lever 14. F1 and F2 designate the bending forces of the rack 17, respectively on flanks 2a and 2b. The bending efforts F1 and F2 are directed towards the sole 6, that is to say that they make it possible to accentuate the curvature of the flanks 2a and 2b. The bending forces F1 and F2 are equivalent, that is to say that the rack 17 substantially substantially evenly rests on the sides 2a and 2b of the shell bottom 2. The user does not have the feeling of have one side tighter than the other.

Le basculement du levier 14 entraine également que le lacet 10 vient se loger dans un cran 160 de la pièce crantée 16. Plus précisément, les orifices 014 de passage du lacet 10 sont séparés de l'arbre d'articulation 140 d'une distance d1 correspondant à la distance d2 entre deux crans de la pièce crantée 16. Ainsi, le lacet 10 se bloque automatiquement dans la pièce crantée 16 par basculement du levier 14. Les deux crans de réception de l'arbre 140 et du lacet 10 sont séparés par un cran vide.The tilting of the lever 14 also causes the lace 10 to be housed in a notch 160 of the notched piece 16. More precisely, the holes 014 for the passage of the lace 10 are separated from the hinge shaft 140 by a distance d1 corresponding to the distance d2 between two notches of the toothed part 16. Thus, the lace 10 is automatically locked in the toothed part 16 by tilting the lever 14. The two receiving notches of the shaft 140 and the lace 10 are separated by an empty screen.

En variante non représentée, le levier 14 peut être enfilé de manière immobile sur le lacet 10.In a variant not shown, the lever 14 can be slid immovably onto the lace 10.

En variante non représentée, le levier 14 est attaché sur le bas de coque 2.In variant not shown, the lever 14 is attached to the shell bottom 2.

Selon une autre variante non représentée, le lacet 10 et le levier 14 peuvent être liés par des points de soudure.According to another variant not shown, the lace 10 and the lever 14 may be bonded by welding points.

Selon une variante non représentée, la pièce crantée 16 et la languette rigide 18 sont d'un seul tenant.According to a variant not shown, the toothed piece 16 and the rigid tongue 18 are in one piece.

Selon une autre variante, le lacet 10 est remplacé par un câble métallique, qui est aussi un élément filiforme.According to another variant, the lace 10 is replaced by a wire rope, which is also a filiform element.

Les caractéristiques techniques des modes de réalisation et variantes envisagés ci-dessus peuvent être combinées entre elles pour générer de nouveaux modes de réalisation de l'invention.The technical features of the embodiments and variants envisaged above can be combined with one another to generate new embodiments of the invention.
