Abstract

The ski boot has its upper surmounted by an ankle which is adjustable on the bottom of the wearer's leg. It has a wedging system (4), acting on the ankle (2), which comprises a wedge (6) rotating on a spindle (7). The wedge extends along the ankle internal wall (16) and near to its upper edge (12). The wedge has a projection (6) which, according to its angular position, retracts in a housing in the ankle or projects on the ankle wall. The wedge projection and its housing are positioned relative to the wedge rotational spindle at the same distance. The wedge is angularly displaced relative to the upper edge by an angle corresponding to the rotation of the wedge between its two wedging positions.

Description

La présente invention concerne les chaussures de sport à coque surmontée d'une tige montante ajustable sur le bas de jambe du porteur à l'aide de dispositifs de serrage, et se rapporte à un dispositif destiné à caler le bas de jambe dans et par rapport à ladite tige.The present invention relates to sports shoes with a shell surmounted by an adjustable rising upper on the lower leg of the wearer using tightening devices, and relates to a device intended to wedge the lower leg in and in relation to to said rod.

Il existe de nombreux dispositifs de calage du bas de jambe surtout dans les chaussures de ski alpin. Ces dispositifs procèdent généralement soit par l'insertion de cales amovibles plus ou moins épaisses entre la tige et le bas de jambe, soit par modification de la position d'éléments de calage qui sont associés à demeure à la tige, soit aussi par modification de la longueur d'une partie du périmètre de la tige autre que celle d'ajustement du serrage.There are many devices for wedging the lower leg, especially in alpine ski boots. These devices generally proceed either by the insertion of more or less thick removable shims between the rod and the lower leg, or by modification of the position of wedging elements which are permanently associated with the rod, or also by modification of the length of a part of the perimeter of the rod other than that of the tightening adjustment.

Ces dispositifs de calage se révèlent indispensables pour, le plus souvent, une bonne adaptation à la morphologie de la partie postérieure du bas de jambe, notamment pour prendre en compte les variations de grosseur des mollets, ainsi que la position de ces derniers par rapport à la hauteur de la tige des chaussures. Ces dispositifs de calage sont également utilisés pour modifier la position d'appui vers l'arrière du bas de jambe par rapport à la tige. Dans ce cas d'utilisation, on modifie par voie de conséquence la position angulaire de l'axe longitudinal médian du bas de jambe par rapport à la base de coque de la chaussure, pour une position angulaire donnée de l'axe longitudinal de ladite tige. En fait, les dispositifs de calage ainsi utilisés procurent ce que l'on appelle communément un réglage de "l'avancée".These wedging devices prove to be essential for, most often, a good adaptation to the morphology of the posterior part of the lower leg, in particular to take into account the variations in size of the calves, as well as the position of the latter relative to the height of the upper of the shoes. These wedging devices are also used to modify the rearward support position of the lower leg relative to the rod. In this case of use, the angular position of the median longitudinal axis of the lower leg is consequently modified relative to the shell base of the shoe, for a given angular position of the longitudinal axis of said upper. . In fact, the timing devices thus used provide what is commonly called an "advance" setting.

On peut citer à titre d'exemple le modèle d'utilité japonais n0 4-6561 qui illustre un dispositif avec une cale amovible et retournable, les brevets suisse n° 677 589 et français n0 2 639 800 qui décrivent des dispositifs dont les éléments de calage sont modifiables en position, et la demande de brevet français n° 2 276 850 qui se rapporte à une cale destinée à modifier la longueur d'une partie du périmètre de la tige autre que la partie d'ajustement du serrage.We can cite as an example the Japanese utility model n 0 4-6561 which illustrates a device with a removable and returnable wedge, the Swiss patents n ° 677 589 and French n 0 2 639 800 which describe devices whose wedging elements are changeable in position, and French patent application No. 2 276 850 which relates to a shim intended to modify the length of a part of the perimeter of the rod other than the tightening adjustment part.

Ces dispositifs permettent d'effectuer le calage du bas de jambe mais présentent cependant plusieurs inconvénients. En effet, dans les exemples de la cale amovible et de la cale destinée à modifier une partie du périmètre de la tige, il est nécessaire de démonter les cales en question pour procéder au calage. Une telle opération est difficile à exécuter hors d'un local protégé car elle requiert de dégager totalement le haut de la tige, voire le déchaussage, et ne peut donc être exécutée correctement sur les pistes de ski, à fortiori dans la neige. Par ailleurs, du fait du démontage des cales, il s'ajoute le risque de les lâcher pendant l'opération, et, sinon de les perdre, d'exiger une recherche et/ou un nettoyage pour qu'elles restent exemptes de toute saleté. Dans l'exemple des dispositifs dont les éléments de calage sont modifiables en position, le risque de perte desdits éléments ne se présente pas mais par contre il est indispensable de disposer d'outils appropriés pour bien exécuter l'opération et également de dégager le haut de la tige. Par ailleurs, comme cela apparaît, ces dispositifs présentent des structures relativement complexes car ils mettent en oeuvre plusieurs pièces métalliques mobiles en translation et ajustées entre elles, par exemple par des montages du type vis-écrou. De telles structures demandent donc d'être protégées des infiltrations de neige, eau, boue, etc..., pour éviter l'encrassement et/ou la détérioration des pièces métalliques les constituant et pour rester aisément manoeuvrables.These devices make it possible to calibrate the lower leg, but nevertheless have several drawbacks. In fact, in the examples of the removable shim and of the shim intended to modify part of the perimeter of the rod, it is necessary to dismantle the shims in question in order to wedge. Such an operation is difficult to perform outside of a protected room because it requires completely clearing the top of the rod, or even heaving, and therefore cannot be performed correctly on the ski slopes, let alone in the snow. Furthermore, due to the dismantling of the shims, there is the risk of dropping them during the operation, and, if not losing them, of requiring research and / or cleaning so that they remain free of any dirt . In the example of devices whose wedging elements can be modified in position, the risk of loss of said elements does not arise, but on the other hand it is essential to have appropriate tools to properly execute the operation and also to clear the top of the stem. Furthermore, as appears, these devices have relatively complex structures because they use several metal parts movable in translation and adjusted to each other, for example by assemblies of the screw-nut type. Such structures therefore need to be protected from the infiltration of snow, water, mud, etc., in order to avoid fouling and / or deterioration of the metal parts constituting them and to remain easily maneuverable.

La présente invention se propose de remédier à ces inconvénients en mettant en oeuvre un dispositif de calage simple, fixe en position sur la tige de la chaussure, donc imperdable, manoeuvrable sans nécessiter son démontage même partiel, n'exigeant pas d'outillage ou de protection particulière pour être mis en oeuvre, notamment sur les pistes de ski et/ou dans la neige, et insensible à l'encrassement.The present invention proposes to remedy these drawbacks by implementing a simple wedging device, fixed in position on the upper of the shoe, therefore captive, maneuverable without requiring its disassembly even partial, requiring no tools or special protection to be implemented, especially on ski slopes and / or in snow, and insensitive to fouling.

A cet effet, la chaussure de sport, dont la base de coque est surmontée d'une tige montante ajustable sur le bas de jambe du porteur à l'aide de dispositifs de serrage, et comportant un dispositif de calage du bas de jambe dans et par rapport à ladite tige en s'interposant entre cette demière et ledit bas de jambe, à proximité du bord supérieur de ladite tige, se caractérise par le fait que le dispositif de calage comporte une cale rotative qui, fixée sur la tige à l'aide d'un axe de rotation et de liaison, s'étend au moins partiellement sur la paroi intérieure de ladite tige, et est réglable angulairement selon au moins deux positions de calage, une position correspondant à un calage maximum et une position correspondant à un calage minimum. Le dispositif de calage se caractérise par le fait que la cale rotative est pourvue d'une saillie qui se présente en relief contre la paroi intérieure de la tige pour la position angulaire de calage maximum, position dans laquelle la cale est alors éloignée de la paroi intérieure de la tige, et donc rapprochée du bas de jambe du porteur, et qui s'escamote dans un logement correspondant obtenu dans la tige pour la position angulaire de calage minimum, position dans laquelle la cale se plaque contre la paroi intérieure de la tige et donc s'éloigne du bas de jambe.To this end, the sports shoe, the shell base of which is surmounted by an adjustable rising rod on the lower leg of the wearer using tightening devices, and comprising a device for wedging the lower leg in and with respect to said rod by interposing between the latter and said lower leg, near the upper edge of said rod, is characterized in that the wedging device comprises a rotating shim which, fixed on the rod to the using an axis of rotation and connection, extends at least partially on the inner wall of said rod, and is angularly adjustable according to at least two setting positions, a position corresponding to a maximum setting and a position corresponding to a minimum stall. The wedging device is characterized by the fact that the rotary shim is provided with a projection which is raised in relief against the internal wall of the rod for the angular position of maximum wedging, position in which the shim is then moved away from the wall. inside of the rod, and therefore close to the lower leg of the wearer, and which retracts into a corresponding housing obtained in the rod for the angular position of minimum stalling, position in which the wedge is pressed against the internal wall of the rod and therefore moves away from the lower leg.

Le contour de la cale est déterminé par rapport au bord supérieur de la tige et en tenant compte de la position de son axe de liaison et de rotation sur celle-ci afin qu'en position angulaire de calage minimum, au moins, son bord ne dépasse pas celui supérieur de ladite tige. Egalement, la saillie dont est pourvue la cale est située sur cette dernière en tenant compte du bord supérieur de la tige et de l'axe de rotation de la cale, afin qu'en position angulaire de calage maximum la saillie se présente en relief contre la paroi intérieure de la tige, à proximité du bord supérieur de ladite tige. Avantageusement, la saillie est allongée et s'étend sensiblement parallèlement au bord supérieur de la tige en position angulaire de calage maximum de la cale.The contour of the shim is determined relative to the upper edge of the rod and taking into account the position of its axis of connection and of rotation thereon so that in angular position of minimum setting, at least, its edge does not not exceed the upper one of said rod. Also, the projection with which the wedge is provided is located on the latter taking into account the upper edge of the rod and the axis of rotation of the wedge, so that in angular position of maximum setting the projection is in relief against the inner wall of the rod, near the upper edge of said rod. Advantageously, the projection is elongated and extends substantially parallel to the upper edge of the rod in the angular position of maximum setting of the wedge.

La cale est pourvue d'un moyen de manoeuvre qui est de préférence saisissable manuellement et accessible de l'extérieur de la tige de la chaussure pour au moins les deux positions angulaires de son réglage. Il est ainsi aisé pour le porteur de placer la cale rotative dans l'une ou l'autre des positions angulaires de calage sans démontage, c'est-à-dire de rendre actif ou inactif le calage dans la zone où est montée la cale.The wedge is provided with an operating means which is preferably manually graspable and accessible from the outside of the upper of the shoe for at least the two angular positions of its adjustment. It is thus easy for the wearer to place the rotary shim in one or the other of the angular positions of chocking without dismantling, that is to say to make the chocking active or inactive in the zone where the chock is mounted. .

Afin d'épouser au plus près le profil de la surface intérieure de la tige, la cale est réalisée sous la forme d'une plaque en un matériau relativement flexible. Ainsi, la cale assure la continuité de la surface d'enveloppement de la tige quelle que soit sa position angulaire. De plus, lorsque sa saillie se place dans le logement correspondant obtenu dans la tige, elle reste maintenue élastiquement dans cette position angulaire.In order to closely match the profile of the inner surface of the rod, the shim is produced in the form of a plate of a relatively flexible material. Thus, the shim ensures the continuity of the wrapping surface of the rod regardless of its angular position. In addition, when its projection is placed in the corresponding housing obtained in the rod, it remains resiliently held in this angular position.

Selon un mode de réalisation utilisant cette flexibilité de la plaque constituant la cale, un système d'emboîtement du type "bossage-creux" est réalisé entre la paroi intérieure de la tige et la saillie dont est pourvue la cale. Ainsi, cette dernière est également maintenue élastiquement dans l'autre position angulaire de calage où sa saillie se présente en relief sur la paroi intérieure de la tige.According to an embodiment using this flexibility of the plate constituting the wedge, a nesting system of the "hollow-boss" type is produced between the inner wall of the rod and the projection of which the shim is provided. Thus, the latter is also held elastically in the other angular wedging position where its projection is in relief on the inner wall of the rod.

Selon divers modes d'application, le dispositif de calage est adapté à différents types de chaussures comme les chaussures à entrée par l'avant, centrale, mixte, ou par l'arrière que l'on connaît en ski alpin.According to various modes of application, the wedging device is adapted to different types of boots such as boots with front, central, mixed, or rear entry that are known in alpine skiing.

Egalement, le dispositif de calage est situé et fixé sur la tige des chaussures, soit sur la partie postérieure de celle-ci, soit sur une partie latérale, soit encore sur la partie antérieure, selon le calage souhaité. A cet effet, la cale rotative du dispositif de calage est préférentiellement fixée de manière amovible par rapport à la tige. Par exemple, son axe de rotation et de liaison peut être démontable. Ainsi, il est possible d'effectuer le montage au choix dans l'une de plusieurs positions de fixation prévues sur la tige en fonction du calage du bas de jambe envisagé. Accessoirement, une telle fixation démontable permet un remplacement aisé de la cale rotative pour des raisons d'esthétique, notamment d'assortiment de couleurs, ou pour des questions techniques relatives à la plage de réglage du calage dont on veut disposer, à la rigidité, etc...Also, the wedging device is located and fixed on the upper of the shoes, either on the rear part thereof, or on a lateral part, or even on the front part, depending on the desired wedging. To this end, the rotary shim of the wedging device is preferably removably fixed relative to the rod. For example, its axis of rotation and connection may be removable. Thus, it is possible to perform the assembly as desired in one of several fixing positions provided on the rod depending on the timing of the lower leg envisaged. Incidentally, such a removable fastening allows easy replacement of the rotary shim for aesthetic reasons, in particular of assortment of colors, or for technical questions relating to the range of adjustment of the timing which one wants to have, to the rigidity, etc ...

Selon une variante de réalisation, la cale rotative est une plaque flexible pourvue d'un prolongement, ou languette, qui s'étend du côté du bas de jambe du skieur nettement au-delà de la saillie, et qui, lorsque la cale est placée en position angulaire de calage maximum, dépasse le bord supérieur de la tige de la chaussure. Ce prolongement constitue ainsi une rehausse d'appui pour le bas de jambe dont la mise en position active s'effectue simultanément avec celle du calage maximum.According to an alternative embodiment, the rotary wedge is a flexible plate provided with an extension, or tongue, which extends from the side of the lower leg of the skier clearly beyond the projection, and which, when the wedge is placed in angular position of maximum setting, exceeds the upper edge of the upper of the shoe. This extension thus constitutes a support enhancement for the lower leg, which is brought into active position simultaneously with that of the maximum setting.

L'invention sera du reste mieux comprise en se reportant à la description qui va suivre en référence aux dessins schématiques annexés montrant, à titre d'exemple, un mode de réalisation du dispositif de calage et diverses applications possibles.The invention will moreover be better understood by referring to the description which follows with reference to the appended schematic drawings showing, by way of example, an embodiment of the wedging device and various possible applications.

Les figures 9 et 10 illustrent la fixation d'un dispositif de calage analogue à celui des figures 1 à 8, mais placé sur l'une des parties latérales de la tige de la chaussure.Figures 9 and 10 illustrate the attachment of a wedging device similar to that of Figures 1 to 8, but placed on one of the lateral parts of the upper of the shoe.

Les figures 11 et 12 montrent une application du dispositif de calage sur la partie antérieure de la tige d'une chaussure de ski du type à entrée par l'arrière.FIGS. 11 and 12 show an application of the wedging device on the front part of the upper of a ski boot of the rear entry type.

La chaussure de sport à tige montante illustrée sur les figures 1 à 8 est une chaussure de ski alpin. Cette chaussure comporte une base de coque 1 surmontée d'une tige 2 ajustable sur le bas de jambe 9 du skieur à l'aide de dispositifs de serrage connus (non représentés) agissant sur la partie antérieure dudit bas de jambe 9, et est dotée d'un dispositif de calage 4 du bas de jambe dans et par rapport à la tige 2. Ce dispositif de calage 4 s'étend sur la paroi intérieure 16 de la tige 2 dans la zone supérieure de celle-ci et s'interpose entre cette dernière et le bas de jambe 9 par le chausson de confort 5 intercalé. Il présente une cale rotative 6 relativement plate et de faible épaisseur qui est retenue sur la tige 2 au moyen d'un axe de rotation et de liaison 7 monté sur un point de fixation 7', et qui est munie d'une salle 8 positionnée à une certaine distance dudit axe 7. Cette saillie 8 peut présenter un profil quelconque, par exemple dans le cas présent un profil demi-circulaire tel que schématiquement représenté et repéré par la référence numérique 8'. La saillie 8 coopère avec la paroi intérieure 16 de la tige 2 afin d'être, selon le calage souhaité, soit en relief, soit escamotée par rapport à celle-ci. A cet effet, la tige 2 est obtenue avec un logement 14 correspondant à la saillie 8 et positionné par rapport à l'axe de rotation 7 à la même distance que celle de la saillie 8. Le logement 14 est par ailleurs décalé angulairement par rapport au bord supérieur 12 de la tige 2 d'un angle correspondant à celui de rotation de la cale 6 entre ses deux postions de calage, dans l'exemple présent de l'ordre de 90°. Ainsi, pour une position angulaire de la cale 6, tel que représenté aux figures 5 à 8, la saillie 8 s'escamote dans le logement 14, et pour une autre position angulaire, tel que représenté aux figures 1 à 4, la saillie 8 se présente en relief contre la paroi intérieure 16 de la tige 2. Il résulte de ces deux positions relatives de la saillie 8 par rapport à la paroi intérieure 16, et cela sans modification de l'ajustement du serrage de la tige 2, que le calage est maximum lorsque la saillie 8 se présente en relief car la cale 6 est éloignée de ladite paroi 16 et rapprochée du bas de jambe 9, et que le calage est minimum lorsque la saillie 8 s'escamote dans le logement 14 car la cale 6 se plaque contre ladite paroi 16 et s'éloigne ainsi du bas de jambe 9.The sports shoe with rising stem illustrated in FIGS. 1 to 8 is an alpine ski boot. This shoe has a shell base 1 surmounted by an adjustable rod 2 on the lower leg 9 of the skier using known tightening devices (not shown) acting on the front part of said lower leg 9, and is provided a wedging device 4 of the lower leg in and relative to the rod 2. This wedging device 4 extends on the inner wall 16 of the rod 2 in the upper zone of it and is interposed between the latter and the lower leg 9 by the comfort liner 5 interposed. It has a relatively flat and thin rotary shim 6 which is retained on the rod 2 by means of a rotation and connection axis 7 mounted on a fixing point 7 ′, and which is provided with a room 8 positioned at a certain distance from said axis 7. This projection 8 can have any profile, for example in the present case a semicircular profile as schematically represented and identified by the reference numeral 8 '. The projection 8 cooperates with the inner wall 16 of the rod 2 so as to be, according to the desired setting, either in relief, or retracted with respect thereto. For this purpose, the rod 2 is obtained with a housing 14 corresponding to the projection 8 and positioned relative to the axis of rotation 7 at the same distance as that of the projection 8. The housing 14 is also angularly offset with respect to at the upper edge 12 of the rod 2 at an angle corresponding to that of rotation of the wedge 6 between its two wedging positions, in the present example of the order of 90 °. Thus, for an angular position of the wedge 6, as shown in Figures 5 to 8, the projection 8 retracts into the housing 14, and for another angular position, as shown in Figures 1 to 4, the projection 8 presents itself in relief against the internal wall 16 of the rod 2. It follows from these two relative positions of the projection 8 relative to the internal wall 16, and this without modifying the adjustment of the tightening of the rod 2, that the wedging is maximum when the projection 8 is in relief because the wedge 6 is distant from said wall 16 and close to the lower leg 9, and the wedging is minimum when the projection 8 retracts into the housing 14 because the wedge 6 is pressed against said wall 16 and thus moves away from the lower leg 9.

S'agissant d'utiliser le dispositif de calage 4 pour une bonne adaptation à la morphologie du bas de jambe 9 du skieur et/ou pour procurer éventuellement une correction dans la valeur de l'angle d'inclinaison dudit bas de jambe 9 par rapport à la base de coque 1, la cale 6 et la saillie 8 sont préférentiellement réalisées dans une faible épaisseur, mais également réalisées dans un matériau relativement flexible tel qu'un plastique, afin d'épouser le plus étroitement possible le galbe et le profil de la partie de la tige 2 où il est monté et ainsi assurer une continuité de la surface d'enveloppement sur le bas de jambe 9. Ainsi, il n'y a pas de risque de détérioration par oxydation ou encrassement par exemple, et d'autre part, les salissures éventuelles qui viendraient s'interposer entre ladite cale 6 et la paroi intérieure 16 de la tige 2 sont automatiquement balayées lors du déplacement en rotation de ladite cale 6. Cette flexibilité permet par ailleurs d'assurer automatiquement l'escamotage de la saillie 8 dans le logement 14 lorsqu'ils sont en vis à vis, et donc la retenue élastique de la cale 6 dans cette position angulaire. Encore, toujours en utilisant cette flexibilité de la cale 6, il est aisé de prévoir un système d'emboîtement du type bossage 18/creux 19 entre la paroi intérieure 16 de la tige 2 et la saillie 8, tel que visible sur les figures 3 et 4. De la sorte, la cale 6 est également maintenue élastiquement dans sa deuxième position angulaire de calage. Il est évident que le système d'emboîtement peut être inversé, c'est-à-dire que le bossage 18 est alors réalisé sur la cale rotative 6 ou sa saillie 8, et que le creux 19 est réalisé dans la tige 2.Regarding the use of the wedging device 4 for a good adaptation to the morphology of the lower leg 9 of the skier and / or to possibly provide a correction in the value of the angle of inclination of said lower leg 9 relative to at the base of the shell 1, the shim 6 and the projection 8 are preferably made in a small thickness, but also made in a relatively flexible material such as plastic, in order to conform as closely as possible to the curve and the profile of the part of the rod 2 where it is mounted and thus ensure continuity of the wrapping surface on the lower leg 9. Thus, there is no risk of deterioration by oxidation or fouling for example, and on the other hand, any dirt which may come between said wedge 6 and the inner wall 16 of the rod 2 are automatically swept when the said wedge 6 is moved in rotation. This flexibility also makes it possible to ensure er automatically the retraction of the projection 8 in the housing 14 when they are opposite, and therefore the elastic retention of the wedge 6 in this angular position. Still, still using this flexibility of the wedge 6, it is easy to provide a nesting system of the boss 18 / hollow 19 type between the inner wall 16 of the rod 2 and the projection 8, as visible in FIGS. 3 and 4. In this way, the wedge 6 is also held elastically in its second angular setting position. It is obvious that the interlocking system can be reversed, that is to say that the boss 18 is then produced on the rotary shim 6 or its projection 8, and that the hollow 19 is produced in the rod 2.

Afin de permettre une manoeuvre aisée de la cale rotative 6 dans l'une ou l'autre de ses positions angulaires de calage, une languette 13 prolonge latéralement la cale 6 vers le haut, au-delà du bord supérieur 12 de la tige 2. Ainsi, que la cale rotative 6 soit en position angulaire de calage maximum ou en position angulaire de calage minimum, se reporter en particulier aux figures 1 et 3 et aux figures 5 et 7, la languette 13 reste accessible de l'extérieur de la tige 2 de la chaussure.In order to allow easy maneuvering of the rotary block 6 in one or other of its angular wedging positions, a tongue 13 laterally extends the block 6 upwards, beyond the upper edge 12 of the rod 2. Thus, whether the rotary shim 6 is in the angular position of maximum setting or in minimum angular position, refer in particular to Figures 1 and 3 and Figures 5 and 7, the tongue 13 remains accessible from the outside of the upper 2 of the shoe.

Le dispositif de calage 4 qui vient d'être décrit en référence aux figures 1 à 8 est présenté, pour exemple, dans le but de procurer une bonne adaptation à la morphologie de la partie postérieure du bas de jambe 9, tel que le mollet du skieur. Ainsi, comme cela est illustré, la position angulaire de l'axe longitudinal médian 20 du bas de jambe 9 par rapport à la base de coque 1 n'a pas été modifié et/ou corrigé par le dispositif de calage 4. Ce dernier a simplement réajusté le chausson 5 contre le bas de jambe 9 tel qu'indiqué par la flèche 22, en provoquant en fait une modification de la longueur d'une partie du périmètre de la tige 2 dont on n'a pas modifié le serrage, lequel est assuré à l'aide des dispositifs de serrage qui agissent sur la partie antérieure du bas de jambe 9.The wedging device 4 which has just been described with reference to Figures 1 to 8 is presented, for example, in order to provide a good adaptation to the morphology of the posterior part of the lower leg 9, such as the calf of the skier. Thus, as illustrated, the angular position of the median longitudinal axis 20 of the lower leg 9 relative to the shell base 1 has not been modified and / or corrected by the wedging device 4. The latter has simply readjusted the liner 5 against the lower leg 9 as indicated by the arrow 22, in fact causing a modification of the length of a part of the perimeter of the rod 2 whose tightening has not been modified, which is ensured using the clamping devices which act on the front part of the lower leg 9.

Ceci étant, il est évident que l'adaptation à la morphologie du bas de jambe 9 peut également se faire en réajustant uniquement le serrage de la tige 2 sur la partie antérieure dudit bas de jambe 9.That said, it is obvious that the adaptation to the morphology of the lower leg 9 can also be done by only readjusting the tightening of the rod 2 on the front part of said lower leg 9.

Dans un tel cas, le dispositif de calage 4 est mis en position angulaire de calage minimum, ce qui fait que le serrage de la tige 2 provoque le recul du bas de jambe 9, et donc le redressement de son axe longitudinal médian 20 par rapport à la base de coque 1. Ce dispositif de calage 4 ainsi utilisé procure donc, par voie de conséquence, un réglage de l'avancée.In such a case, the wedging device 4 is placed in the angular position of minimum wedging, which means that the tightening of the rod 2 causes the lower leg 9 to retreat, and therefore the straightening of its median longitudinal axis 20 relative to to the shell base 1. This wedging device 4 thus used therefore provides, consequently, an adjustment of the advance.

Dans l'exemple qui vient d'être décrit en référence aux figures 1 à 8, le dispositif de calage 4 est situé sur la partie postérieure de la tige 2 de la chaussure pour procurer plus particulièrement une adaptation de la tige 2 à l'arrière du bas de jambe 9, tel que le mollet du skieur. Il est bien entendu que le dispositif de calage 4 peut également être situé et fixé sur les parties latérales de la tige 2 de la chaussure comme illustré schématiquement sur les figures 9 et 10. Encore, la tige 2 de la chaussure peut être prévue avec au moins deux positions de montage du dispositif de calage. Dans un tel cas de construction, la tige 2 est obtenue avec autant de logements 14 et de points de fixation 7' de l'axe 7 qu'il y a de positions de montage.In the example which has just been described with reference to FIGS. 1 to 8, the wedging device 4 is located on the rear part of the upper 2 of the shoe to more particularly provide an adaptation of the upper 2 at the rear lower leg 9, such as the skier's calf. It is understood that the wedging device 4 can also be located and fixed on the lateral parts of the upper 2 of the shoe as illustrated diagrammatically in FIGS. 9 and 10. Again, the upper 2 of the shoe can be provided with at minus two mounting positions for the timing device. In such a construction case, the rod 2 is obtained with as many housings 14 and fixing points 7 'of the axis 7 as there are mounting positions.

Egalement, figures 11 et 12, le dispositif de calage 4 peut être adapté à la tige 32 d'une chaussure de ski du type à entrée par l'arrière. Dans ce type de chaussure, l'ajustement du serrage s'effectue par la partie postérieure ou capot arrière de la tige 32 qui est plus ou moins rapprochée de la partie antérieure, ou manchette.Also, FIGS. 11 and 12, the wedging device 4 can be adapted to the upper 32 of a ski boot of the rear entry type. In this type of shoe, the tightening is adjusted by the rear part or rear cover of the rod 32 which is more or less close to the front part, or cuff.

Enfin, le dispositif de calage 4 peut avantageusement être prévu amovible, par exemple en rendant son axe de liaison et de rotation 7 démontable de son point de fixation 7', afin de permettre une adaptation "à la demande" du skieur ou le remplacement aisé de la cale rotative 6 par une cale possédant une plage de réglage plus ou moins importante que celle "standard" prédéterminée, c'est-à-dire que la saillie 8 peut être peu ou très en relief. Ainsi, selon la hauteur de la saillie 8, le changement de position angulaire de la cale 6 choisie procure une variation plus ou moins importante de la position relative de ladite cale 6 par rapport à la paroi intérieure 16 de la tige 2.Finally, the wedging device 4 can advantageously be provided removable, for example by making its connection and rotation axis 7 removable from its fixing point 7 ', in order to allow adaptation "on demand" of the skier or easy replacement of the rotary shim 6 by a shim having a greater or lesser adjustment range than that predetermined "standard", that is to say that the projection 8 may be little or very in relief. Thus, depending on the height of the projection 8, the change in angular position of the shim 6 chosen provides a more or less significant variation in the relative position of said shim 6 relative to the inner wall 16 of the rod 2.

Il est évident que la cale 6 du dispositif de calage 4 peut être pourvue d'un prolongement qui s'étend, du côté du bas de jambe 9 du skieur, au-delà de la saillie 8, et qui, lorsque la cale 6 est en position angulaire de calage maximum, dépasse le bord supérieur 12 de la tige 2. La cale 6 ainsi obtenue et positionnée angulairement constitue alors l'équivalent d'une rehausse d'appui pour le bas de jambe 9 qui met en oeuvre simultanément le calage proprement dit.It is obvious that the wedge 6 of the wedging device 4 can be provided with an extension which extends, on the side of the lower leg 9 of the skier, beyond the projection 8, and which, when the wedge 6 is in the angular position of maximum setting, exceeds the upper edge 12 of the rod 2. The wedge 6 thus obtained and angularly positioned then constitutes the equivalent of a support riser for the lower leg 9 which simultaneously implements the setting proper.
