Description

La présente invention concerne un dispositif de retenue d'une chaussure de ski sur une planche de glisse tel qu'un ski.The present invention relates to a device for retaining a ski boot on a board glides like a ski.

L'invention concerne plus particulièrement un perfectionnement pour dispositif destiné à retenir sur un ski de façon déclenchable l'avant de la chaussure de l'utilisateur.The invention relates more particularly to a improvement for device intended to retain on a triggerable ski at the front of the boot the user.

En général, la chaussure d'un skieur est retenue sur le ski de façon déclenchable par son extrémité avant grâce à une fixation avant communément appelée "butée", et par son extrémité arrière, notamment son talon, grâce à une fixation arrière communément appelée "talonnière".In general, the shoe of a skier is retained on the ski so that it can be triggered by its end front thanks to a front fixing commonly called "stop", and by its rear end, in particular its heel, thanks to a rear attachment commonly called "heel piece".

En cas d'efforts importants, la libération de la chaussure de ski mettant en danger la jambe ou les articulations du skieur se fait par libération soit de l'avant, soit du talon de la chaussure, soit des deux à la fois. A cet effet, la butée avant comprend, par exemple, une mâchoire pivotant au moins latéralement, tandis que la talonnière comprend généralement une mâchoire montée pivotante pour pivoter vers le haut autour d'un axe transversal, la mâchoire de la butée et celle de la talonnière étant chacune sollicitées par un ressort de déclenchement dont la compression est réglable pour assurer au skieur une valeur d'effort adaptée pour la libération de sa chaussure.In the event of significant efforts, the release of the ski boot endangering the leg or joints of the skier is done by release either of the front, either from the heel of the shoe, or from both to that time. For this purpose, the front stop includes, for example, a jaw pivoting at least laterally, while the heel piece generally includes a swivel mounted jaw for pivoting up around a transverse axis, the jaw of the stopper and that of the heel piece being each requested by a trigger spring whose compression is adjustable to provide the skier with an effort value adapted for the release of his shoe.

On connaít déjà de très nombreuses fixations de sécurité avant destinées à maintenir l'avant d'une chaussure sur un ski pour permettre au skieur, d'une part, la pratique du ski et, d'autre part, la libération de sa chaussure quand il apparaít une sollicitation dangereuse pour la jambe. De telles fixations comprennent une mâchoire pivotante sollicitée en position centrée de retenue par un système élastique tel qu'un ressort.We already know many fixings of front safety intended to maintain the front of a shoe on a ski to allow the skier to on the one hand, the practice of skiing and, on the other hand, the release of his shoe when he appears a dangerous load on the leg. Such fasteners include a stressed pivoting jaw in centered position of restraint by an elastic system such as a spring.

La présente invention entend donc résoudre les inconvénients des fixations antérieures en proposant une nouvelle fixation très compacte et comprenant un minimum de pièces, destinée à retenir l'extrémité avant de la chaussure selon laquelle la zone vers l'avant au-delà de la mâchoire est libérée.The present invention therefore intends to resolve the disadvantages of previous fixings by proposing a new, very compact binding including a minimum of parts, intended to retain the front end of the shoe that the forward area beyond of the jaw is released.

Ainsi, la fixation de l'invention plus particulièrement adaptée pour retenir de façon déclenchable l'extrémité avant de la chaussure du skieur est du type qui comprend une mâchoire mobile en pivotement sur une embase autour d'un axe vertical, contre l'action de moyens de rappel élastiques, et est caractérisée en ce que les moyens de rappel élastiques sont constitués par deux bras d'actionnement sollicités par un système élastique, chacun des bras d'actionnement indépendants de la mâchoire étant pivotant autour d'un axe de pivotement tandis que la mâchoire coopère avec les bras d'actionnement grâce à un organe d'entraínement qui lui est solidaire, lesdits moyens de rappel élastiques étant, par ailleurs, disposés sous l'extrémité avant de la chaussure en arrière du plan transversal passant par l'axe de pivotement de la mâchoire. Le système élastique peut être bien entendu de tout type, comme par exemple du type fonctionnant à la compression ou à la traction, autre, comme par exemple torsion.Thus, the fixation of the invention more particularly suitable for retaining trigger the front end of the shoe skier is of the type which includes a movable jaw in pivoting on a base around a vertical axis, against the action of elastic return means, and is characterized in that the elastic return means consist of two actuated actuating arms by an elastic system, each of the arms actuation independent of the jaw being pivoting about a pivot axis while the jaw cooperates with the actuating arms thanks to a drive member which is integral with it, said elastic return means being, moreover, arranged under the front end of the shoe in back of the transverse plane passing through the axis of pivoting of the jaw. The elastic system can of course be of any type, such as type operating in compression or traction, other, such as twist.

Selon des caractéristiques complémentaires, les deux bras d'actionnement sont sollicités par le système élastique contre au moins une butée d'appui fixe, tandis que l'organe d'entraínement est constitué par une saillie cylindrique s'étendant vers le bas et dont l'axe est avantageusement disposé en arrière par rapport à l'axe de pivotement de la mâchoire.According to additional characteristics, the two actuating arms are requested by the system elastic against at least one fixed support stop, while the drive member is constituted by a downwardly extending cylindrical projection of which the axis is advantageously arranged behind by relative to the pivot axis of the jaw.

Selon une caractéristique du dispositif de l'invention, chacun des deux bras est un levier dit du troisième genre, selon lequel, le point d'application de l'effort est disposé entre le point d'appui, c'est-à-dire le point de pivotement du bras, et le point de résistance, c'est-à-dire le point d'application du système élastique.According to a characteristic of the the invention, each of the two arms is a lever called the third kind, according to which, the point of application of the effort is placed between the fulcrum, that is to say the pivot point of the arm, and the point of resistance, i.e. the point of application of elastic system.

Selon une autre caractéristique, l'organe d'entraínement est relié à la mâchoire par l'intermédiaire d'une plaque avant s'étendant sensiblement horizontalement et sur laquelle est destiné à s'appuyer le dessous de l'avant de la semelle de la chaussure pour constituer pour celle-ci des moyens d'appui vers le bas.According to another characteristic, the organ is connected to the jaw by through a front plate extending substantially horizontally and on which is intended to rest on the underside of the front of the sole of the shoe to constitute for it down support means.

Ajoutons que la saillie cylindrique constituant l'organe d'entraínement est retenue en position centrée par deux rampes d'actionnement réalisées sur deux bras d'actionnement, chacune des deux rampes d'actionnement étant réalisée par la bordure avant de la première portion correspondante du bras d'actionnemnent correspondant, chacune des rampes comprenant, par ailleurs, une première portion de rampe ou rampe de retenue, prolongée par une deuxième portion de rampe ou rampe de déclenchement, le passage de l'organe d'actionnement de la première portion de rampe à la deuxième portion de rampe assurant ainsi la valeur de l'effort de déclenchement libérant la chaussure.Let us add that the cylindrical projection constituting the drive member is retained in a centered position by two actuating ramps made on two arms actuation, each of the two actuation ramps being carried out by the front border of the first corresponding portion of the actuating arm corresponding, each of the ramps comprising, by elsewhere, a first portion of ramp or ramp of restraint, extended by a second portion of ramp or trigger ramp, the passage of the organ actuation of the first ramp portion at the second portion of ramp thus ensuring the value of the release force releasing the shoe.

Notons aussi que le dispositif de retenue de l'invention est caractérisé en ce que chacun des bras d'actionnement, le bras gauche et le bras droit, est articulé autour d'un axe de pivotement respectivement pour s'étendre sous la zone occupée par l'extrémité de la chaussure par une première portion s'étendant en direction du plan de symétrie prolongé par une deuxième portion s'étendant côte à côte vers l'arrière, tandis que leurs extrémités respectives sont sollicitées par le système élastique contre la butée fixe.Note also that the the invention is characterized in that each of the arms actuation, the left arm and the right arm, is articulated around a pivot axis respectively to extend under the area occupied by the end of the shoe by a first portion extending in direction of the plane of symmetry extended by a second portion extending side by side rearward, while that their respective ends are stressed by the elastic system against the fixed stop.

Dans un mode d'exécution, l'embase est fixée au ski, tandis que dans un autre mode le dispositif de retenue est disposé à l'avant d'une plaque pivotante articulée à son extrémité avant autour d'un axe de pivotement transversal.In one embodiment, the base is fixed to the skiing, while in another mode the device retainer is arranged in front of a swivel plate articulated at its front end around an axis of transverse pivoting.

Selon cet autre mode d'exécution, l'embase est articulée autour de l'axe de pivotement transversal pour être prolongée vers l'arrière pour constituer la plaque pivotante qui comprend à l'avant la mâchoire de retenue et à l'arrière des moyens de retenue destinés à retenir l'arrière de la chaussure.According to this other embodiment, the base is articulated around the transverse pivot axis to be extended backwards to constitute the swivel plate which includes at the front the jaw of retaining and at the rear retaining means intended for hold the back of the shoe.

On a compris que la fixation de l'invention, qui laisse libre la zone avant de la mâchoire, est tout à fait adaptée pour équiper les skis de randonnée qui nécessitent la levée du talon de l'utilisateur lors de sa progression.It was understood that the fixing of the invention, which leaves the front area of the jaw free, made to fit touring skis which require lifting the user's heel when its progression.

La fixation avant selon l'invention portant la référence générale (1) de plan longitudinal de symétrie générale (P) est fixée sur la surface supérieure (2) du ski (3) et comprend un organe de retenue (4) de la chaussure, formant une mâchoire emboítant l'avant (5) de la chaussure (50), ladite mâchoire étant disposée pivotante sur une embase (6) autour d'un axe vertical (7) s'étendant vers le haut dans le plan de symétrie (P) .The front binding according to the invention carrying the general reference (1) of longitudinal plane of symmetry general (P) is fixed on the upper surface (2) of the ski (3) and comprises a retaining member (4) of the shoe, forming a jaw fitting the front (5) of the shoe (50), said jaw being disposed pivoting on a base (6) around a vertical axis (7) extending upward in the plane of symmetry (P).

La mâchoire (4) est sollicitée et maintenue en position centrée de retenue grâce à des moyens de rappel élastiques (8) comprenant un organe d'entraínement (9), deux bras d'actionnement (10a, 10b), un système élastique (11) et une butée d'appui fixe (12).The jaw (4) is stressed and held in place centered restraint position by means of elastic return (8) comprising a member drive (9), two actuating arms (10a, 10b), an elastic system (11) and a stop fixed support (12).

Ainsi, à la mâchoire (4) est lié un organe d'entraínement (9) constitué par une saillie cylindrique s'étendant vers le bas et dont l'axe (13) est avantageusement disposé en arrière par rapport à l'axe (7) de pivotement de la mâchoire (4). Thus, to the jaw (4) is linked an organ drive (9) consisting of a projection cylindrical extending downwards and whose axis (13) is advantageously arranged behind with respect to the pivot axis (7) of the jaw (4).

Ainsi, la saillie cylindrique constituant l'organe d'entraínement est retenue en position centrée par deux rampes d'actionnement (14a, 14b) réalisées sur deux bras d'actionnement (10a, 10b).Thus, the cylindrical projection constituting the drive member is retained in a centered position by two actuating ramps (14a, 14b) produced on two actuating arms (10a, 10b).

Ajoutons que l'organe d'entraínement (9) est relié à la mâchoire (4) par l'intermédiaire d'une plaque avant (90) s'étendant sensiblement horizontalement et sur laquelle est destiné à s'appuyer le dessous de l'avant de la semelle de la chaussure pour constituer les moyens d'appui vers le bas pour ladite chaussure. Par ailleurs, cette plaque avant (90) comprend à son extrémité avant une saillie verticale (91) s'étendant vers le haut et destinée à coopérer par coopération de formes avec la face avant (40) de la mâchoire (4) de façon à ce que le pivotement de ladite mâchoire provoque l'entraínement en pivotement de ladite plaque avant (90). On notera aussi que la mâchoire comprend des moyens de réglage en hauteur (41) et qu'elle est mobile en translation verticale par rapport à la saillie verticale (91) qui lui en assure le guidage.Add that the drive member (9) is connected to the jaw (4) via a front plate (90) extending substantially horizontally and on which is intended to rest the underside of the front of the sole of the shoe to constitute the downward support means for said shoe. Furthermore, this front plate (90) includes a vertical projection at its front end (91) extending upwards and intended to cooperate by cooperation of shapes with the front face (40) of the jaw (4) so that the pivoting of said jaw causes the pivoting drive of said front plate (90). Note also that the jaw includes height adjustment means (41) and that it is movable in vertical translation by relative to the vertical projection (91) which ensures it guidance.

Comme on l'a vu précédemment, les moyens de rappel (8) comprennent deux bras d'actionnement (10a, 10b) pivotants sollicités en position centrée contre la butée fixe d'appui (12) grâce à un système élastique (11).As we saw earlier, the means of reminder (8) include two actuating arms (10a, 10b) pivoted stressed in the centered position against the fixed support stop (12) thanks to a system elastic (11).

Chacun des bras d'actionnement, c'est-à-dire le bras gauche (10a) et le bras droit (10b), est donc articulé autour d'un axe de pivotement respectivement (15a, 15b) pour s'étendre sous la zone occupée par l'extrémité de la chaussure par une première portion (16a, 16b) s'étendant en direction du plan de symétrie (P) prolongé par une deuxième portion (17a, 17b) s'étendant côte à côte vers l'arrière, tandis que leurs extrémités respectives sont sollicitées par le système élastique contre la butée fixe (12).Each of the actuating arms, i.e. the left arm (10a) and the right arm (10b), is therefore articulated around a pivot axis respectively (15a, 15b) to extend under the area occupied by the end of the shoe by a first portion (16a, 16b) extending towards the plane of symmetry (P) extended by a second portion (17a, 17b) extending side by side backwards, while their respective ends are requested by the system elastic against the fixed stop (12).

Notons aussi que l'organe d'entraínement (9) est disposé dans le plan de symétrie (P) de même que la butée fixe (12), tandis que les deux bras d'actionnement (10a, 10b) sont avantageusement symétriques par rapport audit plan de symétrie générale (P) .Note also that the drive member (9) is arranged in the plane of symmetry (P) as well as the fixed stop (12), while the two arms actuation (10a, 10b) are advantageously symmetrical with respect to said general plane of symmetry (P).

Par ailleurs et selon une caractéristique de l'invention, les moyens de rappel élastiques (8) sont disposés sous l'extrémité avant (5) de la chaussure de l'utilisateur. Ainsi, l'organe d'entraínement (9), les deux bras d'actionnement (10a, 10b), le système élastique (11) et la butée d'appui fixe (12) sont disposés en arrière (AR) du plan transversal (T) passant par l'axe vertical (7) de pivotement de la mâchoire (4).Furthermore and according to a characteristic of the invention, the elastic return means (8) are arranged under the front end (5) of the boot the user. Thus, the drive member (9), the two actuating arms (10a, 10b), the system elastic (11) and the fixed support stop (12) are arranged behind (AR) the transverse plane (T) passing through the vertical pivot axis (7) of the jaw (4).

On notera que les deux rampes d'actionnement (14a, 14b) sont réalisées par la bordure avant de la première portion (16a, 16b) correspondante du bras d'actionnement correspondant. Chacune des rampes (14a, 14b) comprend une première portion de rampe (140a, 140b) ou rampe de retenue prolongée par une deuxième portion de rampe (141a, 141b) ou rampe de déclenchement. Le passage de l'organe d'actionnement (9) de la première portion de rampe (140a, 140b) à la deuxième portion de rampe (141a, 141b) assure la valeur de l'effort de déclenchement libérant la chaussure. La configuration de la première portion de rampe (140a, 140b), crée la valeur de l'effort du rappel élastique, ainsi que la variation de cet effort, en fonction du déplacement de la chaussure, c'est-à-dire que la forme de la courbe de déclenchement est définie par la forme et la dimension de la rampe, ce qui permet par modification de la rampe de modifier la courbe de déclenchement.Note that the two actuation ramps (14a, 14b) are made by the front edge of the first corresponding portion (16a, 16b) of the arm corresponding actuation. Each of the ramps (14a, 14b) includes a first ramp portion (140a, 140b) or retaining ramp extended by a second ramp portion (141a, 141b) or ramp trigger. The passage of the actuator (9) from the first ramp portion (140a, 140b) to the second ramp portion (141a, 141b) ensures the value of the release force releasing the shoe. The configuration of the first ramp portion (140a, 140b), creates the value of the elastic return force, as well as the variation of this effort, depending on the movement of the shoe, i.e. the shape of the trigger curve is defined by the shape and the dimension of the ramp, which allows for modify the ramp modify the curve trigger.

Le système élastique de rappel (11) en position centrée des bras d'actionnement (10a, 10b) peut être de tout type comme, par exemple, celui illustré aux figures 1 à 5. Selon ce mode d'exécution, il est constitué par une bague élastique enserrant les deux premières portions (16a, 16b) des deux bras d'actionnement (10a, 10b). Lors d'une sollicitation de la chaussure, il y aura ainsi pivotement de la mâchoire (4) autour de son axe de pivotement (7) qui, grâce à son organe d'entraínement (9), entraínera le bras correspondant (10b) en pivotement autour de son axe de pivotement (15b) tel que cela est représenté plus particulièrement à la figure 4, et ce, par extension et déformation élastique de la bague élastique (11) qui a tendance à ramener le bras correspondant en appui sur la butée (12). Ladite bague pouvant être par exemple en matériau du type élastomère ou similaireThe elastic return system (11) in position centered actuation arms (10a, 10b) can be any type like, for example, the one illustrated in Figures 1 to 5. According to this embodiment, it is consisting of an elastic ring enclosing the two first portions (16a, 16b) of both arms actuation (10a, 10b). During a solicitation from the shoe, there will be pivoting of the jaw (4) around its pivot axis (7) which, thanks to its drive member (9), will train the arm corresponding (10b) pivoting about its axis of pivot (15b) as shown more particularly in Figure 4, by extension and elastic deformation of the elastic ring (11) which has tendency to bring the corresponding arm back on the stop (12). Said ring can be for example in elastomeric or similar material

La fixation avant (1) de l'invention peut être, bien entendu, utilisée sur tout type de ski comme, par exemple, un ski alpin destiné à la pratique de la randonnée tel que cela est illustré aux figures 1, 2, 3 et 4 et aux figures 8 et 9.The front fixing (1) of the invention can be, of course, used on any type of ski like, for example example, an alpine ski intended for the practice of hike as shown in Figures 1, 2, 3 and 4 and Figures 8 and 9.

Selon ce mode d'exécution, la fixation avant (1) de l'invention est disposée à l'avant d'une plaque pivotante (25). Ainsi, l'embase (6) articulée autour d'un axe de pivotement transversal (26) est prolongée vers l'arrière pour constituer la plaque pivotante (25) et est articulée à son extrémité avant autour de l'axe de pivotement transversal (26). Ledit axe est retenu par un étrier de montage (27) comprenant deux parois latérales (28a, 28b) retenant l'axe de pivotement transversal (26), tandis qu'elles sont reliées par une plaque de base (29) fixée au ski (3) par un ensemble de vis (30).According to this embodiment, the front fixing (1) of the invention is arranged at the front of a plate pivoting (25). Thus, the base (6) articulated around a transverse pivot axis (26) is extended backwards to form the pivoting plate (25) and is articulated at its front end around the axis transverse pivot (26). Said axis is retained by a mounting bracket (27) comprising two walls lateral (28a, 28b) retaining the pivot axis transverse (26), while they are connected by a base plate (29) fixed to the ski (3) by a set of screw (30).

On notera que l'extrémité arrière de la plaque pivotante (25) comprend des moyens de retenue (31) destinés à retenir l'arrière de la chaussure, tandis qu'un système mobile de retenue arrière (32) permet de bloquer l'arrière de la plaque (25) sur le ski, tel qu'illustré à la figure 8 ou de la libérer tel que cela est représenté à la figure 9, permettant ainsi le pivotement vers le haut de la plaque autour de son axe de pivotement transversal (26).Note that the rear end of the plate pivoting (25) comprises retaining means (31) designed to hold the back of the shoe, while that a mobile rear restraint system (32) allows block the back of the plate (25) on the ski, as as illustrated in figure 8 or to release it like that is shown in Figure 9, allowing the pivoting up of the plate around its axis transverse pivot (26).

Bien entendu, la fixation avant (1) de l'invention peut être utilisée dans le cadre de la pratique du ski alpin classique tel que cela est illustré' à la figure 10. Dans cette variante, l'embase (6) est fixée au ski par un ensemble de vis (30). On notera que la fixation peut être avantageusement utilisée pour équiper des skis courts ou similaires tels que des patinettes, ayant par exemple une longueur inférieure à un mètre.Of course, the front fixing (1) of the invention can be used in the context of classic alpine skiing as it is illustrated 'in Figure 10. In this variant, the base (6) is fixed to the ski by a set of screws (30). We note that the fixing can be advantageously used to equip short skis or similar such as scooters, for example having a length less than a meter.

Dans les deux applications précédemment décrites, on constate que les moyens de rappel élastiques (8) sont disposés sous l'extrémité avant (5) de la chaussure de l'utilisateur. Ceci présente un avantage important qui consiste à libérer la zone (Z) disposée devant la mâchoire (4), ce qui permet notamment le pivotement de la plaque (25) dans le mode d'exécution des figures 8 et 9.In the two applications previously described, it can be seen that the elastic return means (8) are arranged under the front end (5) of the user's shoe. This has an advantage important which consists in freeing the zone (Z) arranged in front of the jaw (4), which allows in particular the pivoting of the plate (25) in the embodiment Figures 8 and 9.

Il va de soi que l'organe de retenue pour la chaussure, constitué par une mâchoire (4) monobloc selon le mode d'exécution illustré aux figures 1 à 4, pourrait être constitué de deux demi-mâchoires, chacune des demi-mâchoires étant articulée autour d'un axe de pivotement et comprenant son propre organe d'entraínement.It goes without saying that the retainer for the shoe, consisting of a one-piece jaw (4) according to the embodiment illustrated in FIGS. 1 to 4, could consist of two half jaws, each half-jaws being articulated around an axis of pivoting and including its own organ training.

Bien entendu, tout type de système élastique peut être utilisé pour agir sur les bras d'actionnement (10a, 10b) et notamment un système du type élastiquement déformable tel qu'illustré à la figure 6. Selon cette variante d'exécution, le système élastique est constitué par un étrier plat réalisé en matériau déformable dont les extrémités coopèrent avec les premières portions (16a, 16b) de chacun des bras d'actionnement (10a, 10b).Of course, any type of elastic system can be used to act on the actuating arms (10a, 10b) and in particular a system of the type elastically deformable as illustrated in Figure 6. According to this variant, the elastic system consists of a flat stirrup made of material deformable whose ends cooperate with the first portions (16a, 16b) of each of the arms actuation (10a, 10b).

Selon les modes d'exécution du système élastique (11) illustré aux figures 1 à 5 et 6, le réglage de l'effort de sollicitation se fait par déplacement du point d'action du système élastique (11) vers l'avant ou vers l'arrière, pour s'éloigner plus ou moins du centre de pivotement des bras. Ainsi, sur la bordure externe de chacun des bras d'actionnement est prévue une succession de crans (110).According to the modes of execution of the elastic system (11) illustrated in FIGS. 1 to 5 and 6, the adjustment of the stressing effort is made by moving the elastic system action point (11) forward or backwards, to move more or less away from the pivot center of the arms. So on the border external of each of the actuating arms is provided a succession of notches (110).

Le système élastique (11) peut être assuré et est, par exemple, constitué comme cela pour illustrer à la figure 7 au moins un ressort et dans l'exemple de réalisation constitué par un étui (18) comprenant deux ressorts (19a, 19b) : un premier ressort de compression (19a) en appui par une de ses extrémités sur un dispositif de réglage (20) et par l'autre de ses extrémités sur le premier bras d'actionnement (10a), et un deuxième ressort de compression (19b) en appui par l'une de ses extrémités sur le fond de l'étui (21) et par l'autre de ses extrémités sur le deuxième bras d'actionnement (10b). Notons que les deux ressorts sont coaxiaux et que leurs axes respectifs sont transversaux pour être perpendiculaires au plan de symétrie générale (P) et leurs axes respectifs sont avantageusement dans le plan général (H) des deux bras d'actionnement qui sont avantageusement réalisés par un profil plat de section rectangulaire.The elastic system (11) can be provided and is, for example, set up like this to illustrate Figure 7 at least one spring and in the example of realization constituted by a case (18) comprising two springs (19a, 19b): a first compression spring (19a) supported by one of its ends on a adjustment device (20) and by the other of its ends on the first actuating arm (10a), and a second compression spring (19b) supported by one of its ends on the bottom of the case (21) and by the other of its ends on the second arm actuation (10b). Note that the two springs are coaxial and that their respective axes are transverse to be perpendicular to the general plane of symmetry (P) and their respective axes are advantageously in the general plan (H) of the two actuating arms which are advantageously made by a flat profile of rectangular section.

Dans le mode de réalisation décrit précédemment, les deux bras d'actionnement (10a, 10b) sont symétriques par rapport au plan (P) de symétrie générale, mais il pourrait en être autrement.In the embodiment described above, the two actuating arms (10a, 10b) are symmetrical with respect to the plane (P) of symmetry general, but it could be otherwise.

Ainsi, et par exemple, les axes de pivotement (15a, 15b) pourraient ne pas être disposés symétriquement par rapport au plan P pour n'avoir pas le même effort de libération de la chaussure vers la droite et vers la gauche. On pourrait aussi prévoir sur chacun des bras une rampe différente pour réaliser cet effet.So, for example, the pivot axes (15a, 15b) may not be arranged symmetrically with respect to the plane P so as not to have the same effort to release the shoe towards the right and left. We could also plan on each of the arms a different ramp to achieve this effect.

Grâce à la description faite précédemment, on notera que les bras d'actionnement (10a, 10b) ne sont pas solidaires de la mâchoire (4), mais lui sont liés cinématiquement.Thanks to the description given above, we note that the actuating arms (10a, 10b) are not not attached to the jaw (4), but are linked to it kinematically.

On notera aussi, que selon une autre caractéristique de l'invention, chacun des bras d'actionnement (10a, 10b) est un levier dit du troisième genre, selon lequel, le point d'application de l'effort (A) est disposé entre le point d'appui, c'est-à-dire le point de pivotement (B), et le point de résistance (C), c'est-à-dire le point d'application du système élastique (11), comme cela apparaít plus particulièrement à la figure 2.It should also be noted that according to another characteristic of the invention, each of the arms actuation (10a, 10b) is a lever called the third kind, according to which, the point of application of the force (A) is placed between the fulcrum, i.e. the pivot point (B), and the resistance (C), i.e. the point of application of the elastic system (11), as appears more particularly in Figure 2.

La figure 11 est une l'illustration d'une variante selon laquelle, chacun des bras d'actionnement a sa propre butée. Ainsi le bras gauche (10a) est en appui sur une butée (12a), tandis que le bras droit (10b) est en appui sur une autre butée (12b), le dispositif comprenant donc deux butées (12a, 12b). Dans cette variante, le système élastique (11) est constitué par un ressort de traction, mais pourrait être aussi, constitué par une bague élastique comme selon la variante illustrée à la figure 5.Figure 11 is an illustration of a variant according to which each of the actuating arms has its own stop. So the left arm (10a) is in support on a stop (12a), while the right arm (10b) is supported on another stop (12b), the device therefore comprising two stops (12a, 12b). In this variant, the elastic system (11) consists by a tension spring, but could also be, constituted by an elastic ring as according to the variant illustrated in Figure 5.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons.Of course, the invention is not limited to embodiments described and represented as examples but it also includes all technical equivalents and their combinations.
