Description

La présente invention concerne un dispositif pour relier une chaussure avec un ski et plus particulièrement l'extrémité de celle-ci.The present invention relates to a device for connecting a boot with a ski and more particularly the end of the latter.

Bien que le dispositif selon l'invention puisse éventuellement être utilisé comme un des éléments reliant L'avant et/ou L'arrière de La chaussure dans Le cas d'une pratique de ski sur piste, il est cependant plus spécialement conçu, dans Le cadre de La présente invention, comme une fixation destinée à relier seuLement L'extrémité avant de La chaussure au ski, Le talon étant libre de se soulever, comme cela se produit dans La pratique du ski de fond ou de randonnée.Although the device according to the invention may possibly be used as one of the elements connecting the front and / or the rear of the boot in the case of skiing on the piste, it is however more specially designed, in the part of the present invention, as a binding intended to connect only the front end of the boot to the ski, the heel being free to lift, as occurs in the practice of cross-country skiing or touring.

On connait de très nombreux dispositifs du genre dont Le chaussage et Le déchaussage se font manuellement par une action volontaire du skieur sur un levier qui est généralement articulé. On peut citer par exemple Les fixations du type normes nordiques qui comportent un étrier pivotant qui doit être manipulé à La main. Ce type de disposition étant.reLativement ancien et bien connu du public, nous n'en parlerons donc pas plus en détail. Pour citer des produits plus récents, on peut noter celui qui est décrit dans Le brevet français N° 2447731 déposé par La demanderesse et qui comporte essentiellement des moyens de manœuvre manuels constitués par un verrou mobile soumis à L'action d'un organe élastique. Ces dispositifs de fixation, s'ils se révèlent répondre aux exigences techniques pour La pratique du ski de fond, en particulier au niveau de l'effort de retenue de La semelle de chaussure sur Le ski, présentent cependant l'inconvénient d'être manoeuvrables manuellement; ces manoeuvres sont relativement fastidieuses car Le skieur doit se baisser sur L'avant en effectuant une flexion importante d'où risque de déséquilibre, ou bien carrément poser un genou à terre, ce qui est souvent malaisé selon La qualité de La neige et/ou du terrain. En outre, dans Le cas des dispositifs de fixation comprenant un verrou pivotant sur une monture articulée, non seulement il est nécessaire de dégager ledit verrou avant présentation de La chaussure sur La fixation, ce qui est vrai également dans Les fixations du type normes nordiques, mais il faut en plus ramener Le verrou sur La partie de semelle correspondante.Many devices of this type are known, including putting on and taking off manually by the skier's voluntary action on a lever which is generally articulated. Mention may be made, for example, of attachments of the Nordic standard type which include a pivoting stirrup which must be handled by hand. This type of provision being relatively old and well known to the public, we will therefore not discuss it in more detail. To cite more recent products, one can note that described in French patent N ° 2447731 filed by The applicant and which essentially comprises manual operating means constituted by a movable lock subjected to the action of an elastic member. These binding devices, if they prove to meet the technical requirements for the practice of cross-country skiing, in particular at the level of the retaining force of the boot sole on the ski, have the disadvantage of being maneuverable. manually; these maneuvers are relatively tedious because the skier must bend over the front by performing a significant flexion where there is a risk of imbalance, or even put a knee on the ground, which is often difficult depending on the quality of the snow and / or ground. In addition, in the case of fastening devices comprising a pivoting lock on an articulated frame, not only is it necessary to release said lock before presentation of the shoe on the binding, which is also true in bindings of the Nordic standards type, but it is also necessary to bring the bolt back onto the corresponding sole part.

D'autres dispositifs, tels que ceux décrits dans La demande de certificat d'addition N° 2 497 674 ou dans Le brevet français N° 2 527 081 ont visé à remédier à ces inconvénients de manipulation en permettant Le chaussage automatique de La chaussure. Par contre, pour permettre Le chaussage automatique, et donc un effort de chaussage compatible avec Les cinématiques connues et employées, iL a fallu diminuer très sensiblement L'effort de retenue habituelLement obtenu en chaussage mandel faute de pouvoir bénéficier d'un axe de pivotement assez grand entre La semelle et Le verrou ainsi que d'une force équivalente à celle manuelle; encore, du fait que le verrou de tels dispositifs de fixation est pivotant autour d'un axe, L'effort exercé par Le système élastique sur celui-ci est réparti sur La semelle de chaussure et sur Ledit axe.Other devices, such as those described in The request for addition certificate No. 2,497,674 or in French patent No. 2,527,081 have sought to remedy these disadvantages of handling tion by allowing automatic shoeing. On the other hand, to allow automatic footwear, and therefore a footwear effort compatible with the known and used kinematics, iL had to very significantly reduce the restraint effort usually obtained in mandel footwear for lack of being able to benefit from a fairly pivot axis large between the sole and the lock as well as a force equivalent to that manual; also, due to the fact that the bolt of such fastening devices is pivotable about an axis, the force exerted by the elastic system thereon is distributed over the sole of the shoe and over said axis.

Le dispositif de fixation selon L'invention se propose de remédier de manière simple et efficace à ces inconvénients en permettant un chaussage aisé nécessitant un effort relativement faibLe tout en assurant un effort de retenue puissant grâce à La Liberté totale de l'axe de pivotement du verrou en position de chaussage, assurant L'action du système élastique uniquement sur le nez de pression dudit verrou. A cet effet L'invention propose un dispositif de Liaison d'une extrémité d'une chaussureThe fastening device according to the invention proposes to remedy these drawbacks in a simple and effective manner by allowing an easy fitting requiring a relatively low effort while ensuring a powerful retaining effort thanks to the total freedom of the pivot axis of the lock in the fitting position, ensuring The action of the elastic system only on the pressure nose of said lock. To this end, the invention provides a device for connecting an end of a shoe.

Selon un mode de réalisation de L'invention, ceLLe-ci est appliquée à un ensemble de fixation de ski de fond du type de ceux décrits précédemment et comporte notamment une partie d'accrochage Liée à La chaussure, une pièce d'appui ou étrier reliée au ski et destinée à recevoir La partie d'accrochage, et un dispositif de verrouillage élastique destiné à retenir Ladite partie d'accrochage sur La pièce d'appui, un support de fixation assurant La liaison du dispositif au ski ; de manière connue en soi, Le dispositif de verrouillage élastique est constitué par un verrou pivotant entre une position de chaussage et une position de déchaussage, et un système élastique associé en pivotement avec Le verrou de sorte que L'action de son organe élastique, ou ressort, sollicite ledit verrou dans ses positions extrêmes. Conformément à L'invention, Le verrou est pivotant autour d'un axe sur lequel il prend appui pendant ses déplacements entre sa position de déchaussage et sa position de chaussage et inversement, tandis qu'en position de chaussage ledit verrou est uniquement en appui sur La partie d'accrochage de La chaussure et La pièce d'appui, son axe de pivotement étant alors flottant. Selon un premier mode de réalisation du dispositif de fixation conformément à L'invention, l'axe autour duquel Le verrou pivote est solidarisé de ce dernier, tandis qu'un Logement de section plus grande destiné à recevoir ledit axe est obtenu sur Le support de fixation. Selon un deuxième mode de réalisation du dispositif, l'axe de pivotement est solidaire du support et Le verrou comporte un Logement de section plus grande à travers lequel passe Ledit axe.According to one embodiment of the invention, this is applied to a cross-country ski binding assembly of the type described above and in particular comprises a hooking part linked to the boot, a support piece or stirrup connected to the ski and intended to receive the hooking part, and an elastic locking device intended to retain said hooking part chage on the support piece, a fixing support ensuring the connection of the device to the ski; in a manner known per se, The elastic locking device is constituted by a pivoting lock between a shoeing position and a heaving position, and an elastic system associated in pivoting with the lock so that the action of its elastic member, or spring, urges said lock in its extreme positions. In accordance with the invention, the lock is pivotable about an axis on which it is supported during its movements between its heaving position and its fitting position and vice versa, while in the fitting position said lock is only supported on The attachment portion of the shoe and the support piece, its pivot axis then being floating. According to a first embodiment of the fixing device in accordance with the invention, the axis around which the bolt pivots is secured to the latter, while a housing of larger section intended to receive said axis is obtained on the support of fixation. According to a second embodiment of the device, the pivot axis is integral with the support and the lock comprises a housing of larger section through which the said axis passes.

Encore, selon un troisième mode de réalisation de l'invention, l'axe de pivotement du verrou est matérialisé par un Logement semi-circulaire obtenu sur Le support dans lequel est engagée une partie profilée du verrou, de préférence de profil conjugué ; Lorsque Le verrou est en position de chaussage, Le système élastique applique ce dernier sur La partie d'accrochage de La chaussure en provoquant son pivotement autour de son point d'appui sur ladite partie d'accrochage jusqu'à ce qu'il vienne en butée sur La pièce d'appui lledit verrou quittant de ce fait son premier appui dans Le Logement semi-circulaire du support.Still, according to a third embodiment of the invention, the pivot axis of the lock is materialized by a semi-circular housing obtained on the support in which is engaged a profiled part of the lock, preferably of conjugate profile; When the lock is in the boot position, the elastic system applies the latter to the attachment portion of the shoe by causing it to pivot about its point of support on said attachment portion until it comes into contact. abutment on the support piece lledit bolt thereby leaving its first support in the semi-circular housing of the support.

Selon une variante de réalisation du dispositif de fixation, Le verrou est agencé en pivotement pour être stable dans ses positions de chaussage et de déchaussage. Avantageusement, en particulier dans Le cas où le verrou est susceptible d'être stable en position de déchaussage, ce dernier est pourvu d'une pédale de rechaussage manoeuvrable à l'aide de La partie d'accrochage de La chaussure.According to an alternative embodiment of the fixing device, the lock is arranged in pivoting so as to be stable in its positions of putting on and taking off. Advantageously, in particular in the case where the bolt is capable of being stable in the heaving position, the latter is provided with a heaving pedal which can be operated using the attachment part of the shoe.

Encore, selon un autre mode de réalisation, le dispositif de verrouillage est manoeuvrable entre ses positions de chaussage et de déchaussage au moyen de L'organe élastique ménagé pour présenter au moins une partie préhensible.Still, according to another embodiment, the device for locking is maneuverable between its booting and heaving positions by means of the elastic member arranged to present at least one gripping part.

Enfin, selon La liberté de mouvement souhaitée au niveau de L'extrémité de La chaussure par rapport au ski, Le support du dispositif de fixation peut être pourvu d'une zone de flexion ou d'un axe de rotation et comporter au moins une butée destinée à Limiter l'amplitude du déplacement de Ladite chaussure de ski.Finally, according to the desired freedom of movement at the end of the boot relative to the ski, the support of the binding device can be provided with a bending zone or with an axis of rotation and include at least one stop. intended to limit the amplitude of movement of said ski boot.

L'invention sera du reste mieux comprise en se reportant à La description qui va suivre en référence aux dessins annexés illustrant, à titre d'exemple, plusieurs modes de réalisation du dispositif.The invention will moreover be better understood by referring to the description which follows with reference to the appended drawings illustrating, by way of example, several embodiments of the device.

Dans La forme de réalisation représentée selon Les figures 1 à 7, Le dispositif comporte une partie d'accrochage (1) solidaire de La chaussure (2), une pièce d'appui (3) reliée au ski (4) par L'intermédiaire d'un support (5), et un système de verrouillage (6) destiné à retenir La partie d'accrochage (1) sur La pièce d'appui (3) au moyen d'un verrou amovible (7), pivoté autour d'un axe (8) par rapport au support (5) et soumis à L'action d'un organe élastique teL que le ressort (9). Le verrou (7) est avantageusement pourvu d'un nez de pression (10) qui, sous La sol- liciatation du ressort (9), figure 1, s'applique sur La partie d'accrochage (1Yet contre La pièce d'appui (3) à La manière d'un coin. TeL que réalisé dans cet exemple, Le ressort (9) est monté pivotant par Les extrémités (11) de ses brins Latéraux (12) sur Le support tandis que sa partie médiane (13) est en pression en un point d'actionnement (140) sur La zone d'actionnement (14) du verrou ; L'axe de pivotement (8) dudit verrou étant situé entre Les extrémités (11) du ressort et sa zone d'actionnement (14). Ainsi, selon que Le point d'actionnement du ressort (9) sur Le verrou est situé d'un côté de l'axe (8), figure 1, ou de L'autre, figure 2, Le verrou est sollicité respectivement en position de chaussage ou en position de déchaussage ; Les extrémités (11) du ressort (9), La partie médiane (13) de celui-ci, et l'axe (8) du verrou, constituant Les trois points d'une genouillère. Des bossages (15) et (16) ménagés sur Le verrou (7) constituent Les limites de La zone d'actionnement (14) du ressort (9). Les positions extrêmes de chaussage et/ou de déchaussage que Le verrou est susceptible d'adopter sont déterminées, respectivement, par La pièce d'appui (3) contre laquelle Le nez de pression (10) est sollicité, figure 1, et par des butées (17) obtenues sur Le support (5) sur lesquelles La partie médiane (13) du ressort (9) vient s'appuyer.In the embodiment represented according to FIGS. 1 to 7, the device comprises a hooking part (1) integral with the boot (2), a support piece (3) connected to the ski (4) by the intermediary a support (5), and a locking system (6) intended to retain the attachment part (1) on the support part (3) by means of a removable lock (7), pivoted around 'an axis (8) relative to the support (5) and subjected to the action of an elastic member such as the spring (9). The lock (7) is advantageously provided with a pressure nose (10) which, under the solicitation of the spring (9), FIG. 1, is applied to the attachment part (1Yet against the support part (3) In the manner of a corner. TeL that produced in this example, the spring (9) is pivotally mounted by the ends (11) of its lateral strands (12) on the support while its middle part (13) is under pressure at an actuation point (140) on the actuation zone (14) of the lock; the pivot axis (8) of said lock being situated between the ends (11) of the spring and its actuation zone (14). Thus, depending on whether the spring actuation point (9) on the lock is located on one side of the axis (8), figure 1, or on the other, figure 2, the lock is stressed respectively in the boot position or in the heaving position; the ends (11) of the spring (9), the middle part (13) thereof, and the axis (8) of the lock, constituting the three points of a knee brace. Bosses (15) and (1 6) formed on the latch (7) constitute the limits of the actuation zone (14) of the spring (9). The extreme shoeing and / or heaving positions that the lock is capable of adopting are determined, respectively, by the support piece (3) against which the pressure nose (10) is biased, FIG. 1, and by stops (17) obtained on the support (5) on which the middle part (13) of the spring (9) comes to bear.

Conformément à l'invention, l'axe de pivotement (8) du verrou (7) est monté flottant dans un Logement (18) réalisé sur Le support (5) de sorte que l'axe (8) perde tout appui dans Ledit Logement Lorsque Le nez de pression (10) dudit verrou est appliqué sur La partie d'accrochage (1) de La chaussure, teL que visible en figure 1 ; inversement, lorsque Le verrou (7) est manoeuvré en position de déchaussage, l'axe (8) reprend appui dans Le logement (19) du support ; Le nez de pression (10) dudit verrou quittant son appui sur La partie d'accrochage. Le fonctionnement sera mieux compris en référence aux figures 3, 4 et 5 : en figure 3, Le verrou (7) est en position stable de déchaussage ; La partie médiane (13) du ressort (9) est passée au-delà du plan (25), passant par Les extrémités (11) des brins (12) dudit ressort et du point d'appui de l'axe (8) du verrou (7) dans Le Logement (19) du support (5) et, sous L'effet du rappel élastique de cette partie (13) qui tend à revenir dans le plan des brins Latéraux (12), Le verrou est maintenu contre Les butées (17) du support (5).According to the invention, the pivot axis (8) of the latch (7) is mounted floating in a housing (18) produced on the support (5) so that the axis (8) loses all support in said housing When the pressure nose (10) of said lock is applied on the attachment part (1) of the shoe, as visible in FIG. 1; conversely, when the lock (7) is maneuvered in the heaving position, the axis (8) resumes support in the housing (19) of the support; The pressure nose (10) of said latch leaving its support on the attachment part. The operation will be better understood with reference to FIGS. 3, 4 and 5: in FIG. 3, the lock (7) is in the stable release position; The middle part (13) of the spring (9) is passed beyond the plane (25), passing through the ends (11) of the strands (12) of said spring and the fulcrum of the axis (8) of the lock (7) in the housing (19) of the support (5) and, under the effect of the elastic return of this part (13) which tends to return to the plane of the lateral strands (12), the lock is held against the stops (17) of the support (5).

Afin de permettre Le chaussage automatique, Le verrou est muni d'une pédale (26) de rechaussage manoeuvrable à L'aide de La partie d'accrochage (1) de La chaussure (2) Lorsque Ladite partie est engagée de haut en bas selon (27) sur La pièce d'appui (3). En figure 4, La partie d'accrochage (1) de La chaussure (2) a provoqué Le pivotement du verrou/selon (28) par action selon (27) sur La pédale (26) de ce dernier et La partie médiane (13) du ressort (9) a été amenée sensiblement dans Le plan (25) ; dans cette position, Le verrou se trouve en position d'équilibre instable car Le sens d'action du ressort se superpose à L'aLignement des points d'appui (11), (8) et (13) de La genouillère. En continuant Le mouvement selon (27), pour que La partie médiane (13) franchisse Le plan (25), ou seuil d'équilibre, Le verrou (7) bascule alors en position de chaussage, figure 5, sous l'effet de La poussée élastique de Ladite partie médiane (13) du ressort (9) qui glisse sur La zone d'actionnement (14) pour trouver appui contre Le bossage (16) en se rapprochant du plan défini par Les brins Latéraux (12) dudit ressort. L'action "F" du ressort (9) étant dirigée au-delà du point d'appui (38) du flanc (100) du nez de pression (10) sur La partie d'accrochage (1) sensiblement dans Le plan (29) passant par Les extrémités (11) et La partie médiane (13), le verrou (7) pivote autour de ce point d'appui (38) selon (36) et son axe (8) quitte son appui dans le Logement (19) du support (5). On s'aperçoit que par une telle disposition, toute L'action du système élastique (6) est reportée sur Le nez de pression (10) du verrou qui vient, à La manière d'un coin, contre La pièce d'appui (3) par son flanc (101) et contre La partie d'accrochage (1) de chaussure par son flanc (100), ladite partie d'accrochage étant ainsi plaquée sur Le ski et sur La zone de butée (30) de ladite pièce d'appui (3).In order to allow automatic putting on, the lock is provided with a pedal (26) which can be maneuvered using the hooking part (1) of the shoe (2) when said part is engaged from top to bottom according to (27) on the support piece (3). In Figure 4, the hooking part (1) of the shoe (2) caused the pivoting of the lock / according to (28) by action according to (27) on the pedal (26) of the latter and the middle part (13 ) of the spring (9) has been brought substantially into the plane (25); in this position, the lock is in an unstable equilibrium position because the direction of action of the spring is superimposed on the alignment of the support points (11), (8) and (13) of the toggle joint. By continuing the movement along (27), so that the middle part (13) crosses the plane (25), or threshold of equilibrium, the lock (7) then switches to the fitting position, FIG. 5, under the effect of The elastic thrust of said middle part (13) of the spring (9) which slides over the actuation zone (14) to find support against the boss (16) while approaching the plane defined by the lateral strands (12) of said spring . The action "F" of the spring (9) being directed beyond the fulcrum (38) of the side (100) of the pressure nose (10) on the hooking part (1) substantially in the plane ( 29) passing through the ends (11) and the middle part (13), the latch (7) pivots around this fulcrum (38) along (36) and its axis (8) leaves its support in the housing ( 19) of the support (5). We notice that by such an arrangement, all the action of the elastic system (6) is transferred to the pressure nose (10) of the bolt which comes, in the manner of a wedge, against the support piece (3) by its side (101) and against the hooking part (1) of the boot by its side (100), said hooking part being thus pressed against the ski and on the area of stop (30) of said support piece (3).

Afin de faciliter l'engagement du nez de pression (10) entre La partie d'accrochage (1) et La pièce d'appui (3), un bossage (31) est associé à ladite pièce d'appui, du côté opposé à La zone de butée (30) ; de préférence, Le bossage (31) s'étend sur La pièce d'appui au moins sensiblement à La hauteur de La pédale de rechaussage (26) Lorsque Le verrou (7) est en position de déchaussage, figure 3, et est centré sur ladite pièce d'appui tandis que Le nez de pression (10) est obtenu avec un évidement (32) offrant Le passage audit bossage, visible en figur 2 et 6 ; ainsi, en engageant La partie d'accrochage (1) sur La pièce d'appui (3), selon (27), Ladite partie (1) glisse tout d'abord sur La face (33) de La pièce d'appui puis sur Le bossage (31), ce qui oblige La chaussure à avancer vers La zone de butée (30). IL est évident que L'épaisseur du bossage sera fonction du passage à obtenir pour Le nez de pression (10). On notera, dans cet exemple de réalisation du dispositif décrit jusqu'à présent, que La partie médiane (13) du ressort (9) peut se déplacer sur La zone d'actionnement (14) entre Les bossages (15) et (16) du verrou ; en considérant que pendant La pratique normale du ski le skieur est susceptible de provoquer sur La chaussure des efforts tendant à dégager La partie d'accrochage(1) de chaussure de La pièce d'appui (3), les efforts antagonistes à ceux du ressort (9) seront absorbés étastiquement par ledit ressort dont La partie médiane (13) glissera plus ou moins sur La zone d'actionnement.In order to facilitate the engagement of the pressure nose (10) between the attachment part (1) and the support part (3), a boss (31) is associated with said support part, on the side opposite to The stop zone (30); preferably, the boss (31) extends over the support piece at least substantially at the height of the raising pedal (26) When the lock (7) is in the lifting position, FIG. 3, and is centered on said support piece while the pressure nose (10) is obtained with a recess (32) providing passage to said boss, visible in FIG 2 and 6; thus, by engaging the attachment portion (1) on the support piece (3), according to (27), said portion (1) slides first on the face (33) of the support piece and then on the boss (31), which forces the shoe to advance towards the stop zone (30). It is obvious that the thickness of the boss will depend on the passage to be obtained for the pressure nose (10). It will be noted, in this embodiment of the device described so far, that the middle part (13) of the spring (9) can move over the actuation zone (14) between the bosses (15) and (16) of the lock; considering that during normal skiing, the skier is likely to cause efforts on the shoe tending to release the shoe attachment part (1) of the support piece (3), the forces opposing those of the spring (9) will be absorbed statically by said spring, the middle part (13) of which will slide more or less over the actuation zone.

Afin de supprimer La sensation de flottement pouvant appa- raitre du fait de cette absorption élastique, une encoche (34), figures 3, 4 et 5, est avantageusement ménagée à La base du bossage (16) dans La position extrême de verrouillage que peut adopter La partie médiane (13) du ressort ainsi arrêtée en position sur La zone d'actionnement (14). Pour manoeuvrer Le dispositif en déchaussage, il suffit de se servir du ressort Lui-même comme d'un levier et de Le repousser d'avant en arrière selon (35), figure 4. Dans un premier temps, La partie médiane (13) va sortir de L'encoche (34) et glisser sur La zone d'actionnement (14) pour venir buter contre Le bossage (15) ; en parcourant La zone (14), L'action du ressort passe de L'autre côté du point d'appui (28) du nez de pression (10), ce qui fait basculer Le verrou (7) et donc son axe (8) en appui contre Le Logement (19). Dans un deuxième temps, en continuant de repousser Le ressort selon (35), Le verrou quitte L'appui (28) sur La partie d'accrochage (1) et pivote dans Le même sens que ledit ressort jusqu'à franchir Le seuil d'équilibre. (25) au-delà duquel Le ressort se détend partiellement en entraînant Le verrou jusqu'à ce qu'il trouve appui sur Les butées (17) de support, figure 3. Le dispositif fonctionnant par un principe à genouillère, La zone d'actionnement (14) du verrou (7) est orientée par rapport à L'accrochage des extrémités (11) du ressort (9) sur Le support (5), de manière à ce que Ledit ressort (9) subisse une mise sous tension relativement importante Lors de La manoeuvre de déchaussage qui s'effectue par des moyens manuels ; L'énergie ainsi accumulée est partiellement utilisée par détente du ressort au-delà du seuil d'équilibre (25) pour venir en appui sur Les butées (17). Bien entendu, Les butées (17) seront réalisées avantageusement au plus près du seuil d'équilibre (25) pour qu'au rechaussage L'effort à fournir selon (27), figure 3, au moyen de La partie d'accrochage, soit d'autant plus faible ainsi que La course nécessaire d'engagement sur la pièce d'appui. Pour cela, selon des variantes de réalisation non représentées, Les butées (17) peuvent être prévues réglables par exemple.In order to suppress the floating sensation which may appear due to this elastic absorption, a notch (34), FIGS. 3, 4 and 5, is advantageously provided at the base of the boss (16) in the extreme locking position that can adopt The middle part (13) of the spring thus stopped in position on the actuation zone (14). To operate the heaving device, it suffices to use the spring itself as a lever and to push it back and forth according to (35), Figure 4. First, the middle part (13) will come out of the notch (34) and slide over the actuation zone (14) to abut against the boss (15); browsing the area (14), the action of the spring passes to the other side of the fulcrum (28) of the pressure nose (10), which causes the latch (7) to tilt and therefore its axis (8) in abutment Housing (19). In a second step, continuing to push the spring along (35), the lock leaves the support (28) on the hooking part (1) and pivots in the same direction as said spring until it crosses the threshold of 'balanced. (25) beyond which the spring partially relaxes by driving the lock until it finds support on the support stops (17), Figure 3. The device operating by a toggle principle, the area of actuation (14) of the latch (7) is oriented relative to the hooking of the ends (11) of the spring (9) on the support (5), so that said spring (9) is subjected to a relatively tensioning important During the heaving maneuver which is carried out by manual means; The energy thus accumulated is partially used by relaxing the spring beyond the equilibrium threshold (25) to come to bear on the stops (17). Obviously, the stops (17) will advantageously be produced as close as possible to the equilibrium threshold (25) so that, when raising the force to be provided according to (27), FIG. 3, by means of the attachment part, all the smaller as well as the necessary stroke of engagement on the support piece. For this, according to variants not shown, the stops (17) can be provided adjustable for example.

Dans ce premier mode de réalisation de L'invention, L'axe (8) de pivotement du verrou (7) est solidaire de celui-ci, figure 7, tandis que Le Logement (19) est ménagé sur Le support (5).In this first embodiment of the invention, the axis (8) of pivoting of the lock (7) is integral with the latter, FIG. 7, while the housing (19) is formed on the support (5).

SeLon un deuxième mode de réalisation, figure 8, L'axe (8) de pivotement est solidarisé du support (5) tandis que Le Logement (19) est ménagé sur Le verrou (7).According to a second embodiment, Figure 8, the pivot axis (8) is secured to the support (5) while the housing (19) is formed on the latch (7).

Bien entendu, selon des variantes de réalisation non représentées, le verrou (7) peut comporter deux ailes formant mortaise du côté de sa partie pivotée sur Le support et ce dernier, venir se Loger à La manière d'un tenon dans Ladite mortaise ; La Liaison entre le verrou et Le support étant réalisée comme précédemment à l'aide d'un axe (8) teL qu'en figures 7 et 8.Of course, according to variant embodiments not shown, the lock (7) may include two wings forming a mortise on the side of its part pivoted on the support and the latter, being housed in the manner of a tenon in said mortise; The connection between the latch and the support being carried out as previously using an axis (8) teL that in Figures 7 and 8.

SeLon un troisième mode de réalisation, figures 9, 10 et 11, L'axe de pivotement (40) du verrou (41) est matérialisé par un Logement (42) semi-circulaire ménagé sur le support (43), Logement contre lequel Le verrou est maintenu en pression, figures 9 et 10, par sa partie profilée (44), de profil conjugué, à l'aide du ressort (45). La position stable déverrouillée, figure 9, est obtenue au moyen d'une butée (170), réalisée surAccording to a third embodiment, FIGS. 9, 10 and 11, the pivot axis (40) of the lock (41) is materialized by a semi-circular housing (42) formed on the support (43), Housing against which the lock is kept under pressure, Figures 9 and 10, by its profiled part (44), of conjugate profile, using the spring (45). The stable unlocked position, FIG. 9, is obtained by means of a stop (170), produced on

le support (43), contre laquelle Le verrou (41) vient prendre appui sous L'effet de l'action du ressort (45). Le mode de fonctionnement est identique à celui des modes de réalisation précédents ; en effet, dès que Le seuil d'équilibre (46) est franchi par Le point d'actionnement (140) du ressort qui prend appui dans Le Logement (141), figure 10, Le verrou est entrainé en rotation selon (47) et son nez de pression (48) s'engage sur La partie d'accrochage (1) de La chaussure (2) ; Lorsque le nez de pression (48) prend appui sur La partie d'accrochage (1), teL qu'en (49), figure 11, Le verrou est alors entraîné en pivotement selon (50) autour de cet appui (49) et sa partie profilée (44) quitte son appui dans Le Logement (42). Pour éviter que le verrou (41) pivote au-de Là de La position de chaussage, Lorsque La partie d'accrochage (1) de chaussure n'est pas engagée, un épaulement (58) est prévu sur Le verrou pour servir de butée vis à vis de La partie supérieure (59) de La pièce d'appui (3).the support (43), against which the lock (41) comes to bear under the effect of the action of the spring (45). The operating mode is identical to that of the preceding embodiments; indeed, as soon as the equilibrium threshold (46) is crossed by the actuation point (140) of the spring which is supported in the housing (141), FIG. 10, the lock is rotated according to (47) and its pressure nose (48) engages on the attachment portion (1) of the shoe (2); When the pressure nose (48) is supported on the attachment part (1), such as in (49), FIG. 11, the lock is then pivotally driven along (50) around this support (49) and its profiled part (44) leaves its support in Le Logement (42). To prevent the latch (41) from pivoting from there the fitting position, when the latching part (1) of the shoe is not engaged, a shoulder (58) is provided on the latch to serve as a stop with respect to the upper part (59) of the support piece (3).

Dans Les différents modes de réalisation décrits précédemment, les ressorts (9, 45) qui constituent L'organe d'énergie du dispositif sont formés de manière à servir de moyen de manœu- vre manuel. IL est cependant aisé de concevoir, figure 12, un moyen de manoeuvre (50) solidaire du verrou (51). Dans cet exemple de réalisation, Le ressort (52) est obtenu sous La forme d'un ressort de traction accroché par son extrémité (53) sur Le support (54) et par son extrémité (55) à une pièce d'appui (56) susceptible d'être déplacée sur La zone d'actionnement (57) constituée par une rampe sensiblement rayonnée. Le verrou (51) est pivoté conformément au montage de La figure 8.In the various embodiments described above, the springs (9, 45) which constitute the energy member of the device are formed so as to serve as a manual operating means. It is however easy to design, FIG. 12, an operating means (50) integral with the lock (51). In this exemplary embodiment, the spring (52) is obtained in the form of a tension spring hooked by its end (53) on the support (54) and by its end (55) to a support piece (56 ) capable of being moved over the actuation zone (57) constituted by a substantially radiated ramp. The lock (51) is pivoted in accordance with the assembly of FIG. 8.

En figures 13, 14 et 15, Le dispositif conforme à L'invention se différencie de celui décrit aux figures 9, 10 et 11, notamment par Le mode de réalisation des moyens de pivotement ainsi que du ressort ; en effet, le verrou (60) est pourvu d'un axe de pivotement (61) tandis que Le Logement (62) recevant Ledit axe est réalisé sur le support (63). Ainsi, figure 13, Le verrou étant en position de déchaussage, l'axe de pivotement (61) est en appui sur Le Logement (62) sous L'action du ressort (64), dont Le point d'actionnement (140) est passé en dessous du seuil d'équilibre (66). En figure 14, Le verrou a été déplacé selon (65) jusqu'au seuil (66) d'équiLibre ïnstable ; L'axe (61) est alors toujours en appui contre Le Logement (62). En continuant de basculer selon (65), figure 15, Le verrou prend appui sur La partie d'accrochage (1) de chaussure (2) ; La direction (67) de L'action du ressort (64) sur Le verrou passant au-delà de l'appui (68) de ce dernier sur La partie d'accrochage, Le verrou pivote selon (69) autour de cet appui et son axe (61) quitte son appui sur Le Logement (62). Dans cet exemple de réalisation, Le ressort (64) est réalisé avec au moins une spire (70) déformable élastiquement dans Le sens (71), figure 15.In Figures 13, 14 and 15, The device according to the invention differs from that described in Figures 9, 10 and 11, in particular by the embodiment of the pivoting means as well as the spring; in fact, the lock (60) is provided with a pivot axis (61) while the housing (62) receiving said axis is produced on the support (63). Thus, in FIG. 13, the lock being in the heaving position, the pivot axis (61) is supported on the housing (62) under the action of the spring (64), the actuation point (140) of which has passed below the equilibrium threshold (66). In FIG. 14, the lock has been moved along (65) up to the threshold (66) of unstable equilibrium; The axis (61) is then always in abutment against the housing (62). Continuing to tilt according to (65), Figure 15, The lock is supported on the hooking portion (1) of shoe (2); The direction (67) of the action of the spring (64) on the latch passing beyond the support (68) of the latter on the attachment part, The latch pivots according to (69) around this support and its axis (61) leaves its support on Housing (62). In this exemplary embodiment, the spring (64) is produced with at least one turn (70) elastically deformable in the direction (71), FIG. 15.

Bien entendu, figures 16 et 17, La pièce d'appui (75) peut être obtenue sous La forme d'un étrier dont Les ailes (76), constituant des tenons d'accrochage, reçoivent par engagement de haut en bas selon (74), figure 17, la partie d'accrochage (71) de chaussure (72) pourvue de fentes LatéraLes (73) de forme complémentaire, constituant des mortaises d'accrochage. Dans ce cas de réalisation, le verrou (77) est monté pivotant autour d'un axe (78) flottant dans un Logement (79) de La même manière que dans Le premier mode de réalisation, figures 1 à 5, et Le verrouiLlage Lors du chaussage s'effectue de façon comparable aux exempLes précédents, Le nez de pression (80) prenant appui sur une partie profilée (81) de La partie d'accrochage. Par contre, Le verrou (77) est agencé en pivotement sans position stable de déchaussage ; ainsi, Lorsque La partie d'accrochage (71) de La chaussure est retirée de La fixation, Le verrou (77) bascule selon (82) sous L'action du ressort (83), son axe (78) venant en appui contre Le Logement (79) tandis que son talon (84) bute contre Les ailes (85) du support (86).Of course, FIGS. 16 and 17, the support piece (75) can be obtained in the form of a stirrup, the wings (76) of which, are hooking pins, receive by engagement from top to bottom according to (74 ), Figure 17, the hooking part (71) of shoe (72) provided with LatéraLes slots (73) of complementary shape, constituting mortises for hooking. In this embodiment, the latch (77) is pivotally mounted around an axis (78) floating in a housing (79) in the same manner as in the first embodiment, Figures 1 to 5, and the latching during the boot is made in a manner comparable to the previous examples, the pressure nose (80) bearing on a profiled part (81) of the attachment part. On the other hand, the lock (77) is pivotally arranged without a stable heaving position; thus, when the hooking part (71) of the shoe is removed from the binding, the lock (77) rocks according to (82) under the action of the spring (83), its axis (78) coming to bear against the Housing (79) while its heel (84) abuts against the wings (85) of the support (86).

La figure 18 montre une première possibilité de montage du dispositif selon L'invention sur un ski (4) par L'intermédiaire d'un support (5) fixe et rigide par rapport audit ski. Dans ce cas de figure, La Levée du talon de chaussure (2) selon (90) est possible grâce à La flexibilité de Ladite chaussure dans sa zone antérieure métatarsienne (91).Figure 18 shows a first possibility of mounting the device according to the invention on a ski (4) by means of a support (5) fixed and rigid relative to said ski. In this case, the lifting of the shoe heel (2) according to (90) is possible thanks to the flexibility of said shoe in its anterior metatarsal area (91).

IL est évident que La Levée du talon de chaussure peut être faciLité par d'autres moyens. Par exemple, figure 19, Le support (95) est relié de manière pivotante au ski (4) autour d'un axe transversal (92) porté par une plaque de base (93). Bien entendu, La Liaison pivotante peut être soumise à L'action d'un élément élastique favorisant Le rapprochement de La chaussure (2) du ski (4). Encore, figure 20, Le support (96) est prévu flexible dans une zone comprise entre sa fixation sur Le ski et La pièce d'appui (97) contre LaqueLLe La partie antérieure (91) de La chaussure (2) est retenue. Selon d'autres variantes de Liaisons mobiles du dispositif sur le ski non représentées, des butées Limitent l'amplitude du mouvement de soulèvement du talon de chaussure.It is obvious that lifting the heel of the shoe can be facilitated by other means. For example, in Figure 19, The support (95) is pivotally connected to the ski (4) around an axis transverse (92) carried by a base plate (93). Of course, the pivoting link can be subjected to the action of an elastic element favoring the approximation of the boot (2) of the ski (4). Again, Figure 20, The support (96) is provided flexible in an area between its attachment to the ski and the support piece (97) against LaqueLLe The front part (91) of the shoe (2) is retained. According to other variants of mobile connections of the device on the ski not shown, stops limit the amplitude of the lifting movement of the shoe heel.
