Definitions

  • the invention relates to a stop for a device for fixing a shoe on a gliding board.
  • This stop is particularly suitable for ski touring. It also relates to a device for fixing a shoe on a sliding board and a sliding board as such equipped with such a fixing device and / or such a stop.
  • the document EP-A1-2353673 describes a stop of a device for fixing a boot on a ski touring. The front binding of the boot rests on two jaws of the stop articulated along longitudinal pivot axes relative to a base of the stop intended to be fixed on the ski touring. Each jaw comprises retaining elements intended to cooperate with the ski touring boot.
  • the two jaws are articulated by a spring system in order to occupy a first stable position known as closed in which the retaining elements cooperate with corresponding hollow parts arranged laterally in the front part of the ski touring boot, in order to fix the boot allowing only its rotational movement about an axis transverse to the ski, and a second stable position called open in which the jaws are separated so that the retaining elements release the boot which can be separated from the ski touring.
  • the front part of the boot is attached to a ski touring ski equipped with such a stopper is positioned by positioning the boot while the two jaws occupy the second open position, then pressing strongly with the sole of the boot on the system spring-based which allows the passage of the articulated jaws towards their first closed position in which they approach the shoe in order to position the retaining elements within complementary hollow parts of the shoe.
  • the document FR-A-2656806 describes a stop according to the preamble of claim 1.
  • This stop further comprises two rods each connected to a jaw by a lateral axis and connected to each other by a central axis, and a pusher.
  • EP-A1-2626116 describes a stop for a device for attaching a boot to a ski, comprising a pusher which has two lateral trigger surfaces each cooperating with a respective ramp of each jaw, this pusher being connected to the base by a trigger spring which makes it possible to control its movement.
  • a drawback of such existing stops is their lack of security in the event of a fall of the skier, in particular in the case of a torsional fall of the skier in a downhill situation of the alpine ski type, implying a torsional movement of the boot relative to the ski during which the boot remains trapped in the stop, which risks inducing injuries to the skier.
  • the purpose of the present invention is to provide a solution for fixing a shoe on a gliding board which overcomes the drawbacks listed above.
  • a first object of the present invention is to provide a solution for fixing a shoe on a gliding board, in particular on a ski touring, guaranteeing optimum safety for the skier in the event of a fall.
  • a second object of the present invention is to provide a solution for fixing a shoe that is simple, easy to maneuver, compact, economical and light.
  • a stop for a device for fixing a boot on a gliding board comprising a base intended to be fixed on the gliding board, and characterized in that it comprises two jaws lateral, each mounted mobile in rotation on the base so as to be able to occupy a closed position in which they are capable of holding a shoe on a gliding board and a spread position in which they are capable of receiving a shoe, a pusher comprising a trigger surface cooperating with a ramp of each jaw, this pusher being connected to the base by a trigger spring which makes it possible to control its movement, and two rods connected together and each connected to a jaw.
  • the following description relates to a stop or front fixing element of a device for fixing a boot on a gliding board (not shown).
  • This stopper secures the front part of the boot and is particularly suitable for the practice of ski touring, but does not exclude use in the context of alpine skiing and / or cross-country skiing. More generally, the stop participates in the constitution of the device for fixing the boot on the gliding board, in combination with a rear heel piece (not shown) optionally ensuring the fixing of the rear part of the boot.
  • the Figures 1 to 17 illustrate a first embodiment of such a stop.
  • the Figures 18 to 26 illustrate a second embodiment of such a stop.
  • an orthonormal coordinate system is associated with the stop, the longitudinal direction X of the stop being the horizontal direction, oriented from the rear towards the front of the stop, this longitudinal direction corresponding by elsewhere in the direction from the rear to the front of a ski on which the stop is intended to be arranged.
  • the transverse direction Y corresponds to the horizontal direction perpendicular to the X direction and oriented from right to left.
  • the horizontal plane thus corresponds to a plane parallel to the surface of a ski on which the stop is intended to be placed.
  • the vertical direction Z is perpendicular to the horizontal plane defined by the X and Y directions and is oriented upwards.
  • the stop according to the embodiments of the invention is substantially symmetrically arranged with respect to a vertical longitudinal median plane, and we will sometimes describe in detail only one side of the stop, the second opposite being similar because it is symmetrical.
  • the stop comprises a base 130 intended to be fixed on a gliding board, and mobile elements arranged on this base 130. It also comprises an upper cover 150 positioned in front of the jaws and covering all or part moving parts. It further comprises a housing 137 substantially cylindrical in the rear part, provided for the reception of a connecting axis of a shoe, not shown.
  • the stop first comprises two rigid jaws 101, arranged laterally and in the rear part of the stop.
  • Each jaw 101 comprises a retaining element 102 intended to ensure the retention of the shoe when the jaw is in a closed position, which will be detailed below.
  • the retaining element 102 is in the form of a retaining pin intended to engage in lateral openings formed in the front part of the shoe. It is thus oriented towards the center of the stop, in a substantially transverse direction.
  • Each jaw extends substantially longitudinally on each side of the stop, so as to be able to cooperate with the two lateral surfaces of a shoe.
  • Each jaw 101 is pivotally mounted relative to the stop, more precisely relative to the base 130, about a substantially vertical axis of rotation 103.
  • the retaining element 102 is positioned in the rear and upper part of the jaw, in particular behind the axis of rotation 103 of the jaw.
  • each retaining element 102 can be moved outward by rotation of the jaw 101, thus allowing the shoe to be put on and taken off.
  • each jaw 101 can occupy a closed position in which its retaining elements 102 are capable of holding a ski boot.
  • a return spring exerts a force on the jaw tending to keep it in its closed position. According to this embodiment, this return spring is a trigger spring 112 which will be described below.
  • each jaw 101 includes reinforcing fins 105, to allow them to undergo high stresses without risk. These fins extend in a substantially horizontal plane XY. They are sufficiently wide and slide in lateral grooves of a pusher 110 which will be described below.
  • Each jaw 101 also includes a particular part arranged around the axis of rotation 103, oriented towards the inside of the stop, of which one end forms a substantially vertical rear surface forming a ramp 104 intended to cooperate with a trigger surface 114 of a pusher 110, according to an operation which will be detailed later.
  • This ramp 104 is arranged at the rear of the axis of rotation 103 of the jaw 101.
  • each jaw 101 further comprises a front end, positioned in front of the axis of rotation 103, supporting a link 120 by a lateral axis 123.
  • each jaw 101 supports a link 120 by a lateral axis 123.
  • the stop therefore comprises two links 120. These two links 120 extend in a substantially transverse direction, angularly variable according to the configuration of the stop, and are hinged together by a central axis 125 disposed in the central part of the stop. Such a central axis 125 is free to move relative to the base 130 of the stop. This central axis 125 is integral with a pusher 110 and its movement is guided by the pusher 110 so that it is a displacement in longitudinal translation.
  • the stop comprises a pusher 110, movable in longitudinal translation.
  • the latter comprises a longitudinal central slide in which is positioned one (or more) stud 131 fixed on the base 130 of the stop.
  • the pusher is subjected to the force of a trigger spring 112, extending longitudinally in a central part of the stop, and of which a rear end is fixed to a rear stop 132 of the base 130 and a front end is fixed on the pusher 110.
  • the latter further comprises two lateral trigger surfaces 114, intended to cooperate with the ramps 104 jaws 101. These trigger surfaces 114 are arranged on the front surface of lateral fingers of the pusher 110; these fingers extend transversely with a forward inclination.
  • the force exerted by the trigger spring 112 is adjustable by moving the rear stop 132 by means of an adjustment screw 133, arranged on the front surface of the stop.
  • the operation of the stop will now be explained. It can occupy three main configurations, known as footwear, ascent and descent or skiing.
  • the figures 4 to 7 illustrate the stopper in the boot configuration.
  • the central axis 125 of the rods 120 is positioned in a rear position, by an actuating device which will be detailed later.
  • the central axis 125 comes almost in the transverse alignment of the two axes of rotation 103 of the jaws 101.
  • This retracted position of the rods induces a traction towards the center on each lateral axis 123 of the rods, which consequently exerts a torque on the jaws 101, and causes the jaws 101 to rotate towards the outside of the stop.
  • each of the jaws 101 is spread outwards by an angle of between 8 and 15 degrees inclusive approximately.
  • the pusher 110 is likewise positioned in a retracted position, in which the trigger spring 112 is slightly compressed.
  • the actuation of the stopper is released by the actuation device which will be described below, so that the pusher 110 returns to its more advanced rest position under the effect of the trigger spring 112, recalling the jaws 101 in rotation to their closed position and the central axis 125 of the rods 120 in the front position, until reaching the descent configuration, represented by the figures 9 to 11 , wherein the retaining elements 102 are fitted into recesses of a shoe, not shown, to hold it.
  • the jaws 101 are kept closed so as to guarantee the maintenance of a shoe, not shown.
  • the jaw has a degree of freedom in rotation around its axis of rotation 103 and can slightly accompany the shoe in a movement outwardly twisting.
  • Such movement of a jaw implies a similar and simultaneous movement of the second jaw 101 inwardly via the rods 120 which connect the two jaws.
  • the two jaws have a certain freedom of rotation which allows them to slightly accompany the shoe in its lateral pressures, at a maximum angle of about 20 degrees, in an elastic stroke of the stop, with a reminder elastic towards the centering of the jaws.
  • Such a stop also advantageously implements a triggering function, which thus provides an essential safety function.
  • the shoe exerts a torsional force on a jaw, the latter can rotate around its axis of rotation 103, as mentioned above.
  • Such a rotation causes a relative displacement of the ramp 104 of the jaw relative to the trigger surface 114 of the pusher 110. This cooperation of the two surfaces is such that the pusher is moved towards the rear, against the trigger spring 112.
  • the stop can be positioned in a third so-called ascent configuration, in which the shoe is held by the jaws in a locked manner, that is to say in which tripping is not possible, is inactive. It is indeed important to prevent any triggering of the stop in a climbing phase, to guarantee the safety of the skier when climbing, preventing especially the loss of a ski.
  • This climb configuration is represented by the Figures 12 to 17 .
  • the stop is further actuated by an advantageous actuation device which will now be described, and which is particularly visible on the figures 6 , 10 , 14 and 15 .
  • This actuating device comprises a front support 140 mounted movable in rotation in its lower front part relative to the base 130 of the stop, around a transverse axis 141, in particular shown on the figures 2 and 12 . It carries a second axis in its second upper rear end, which forms an axis of rotation 142 for a lever 143.
  • a lever 143 comprising a gripping zone for its easy manipulation by a user is mounted so as to rotate about this axis of rotation 142 substantially transverse; it is further requested by an optional return spring disposed around this axis of rotation 142.
  • the actuating device further comprises an intermediate piece 144 whose front end is fixed to the front support 140 and / or to the lever 143 at the level of the axis of rotation 142 of the lever.
  • This intermediate piece 144 finally comprises a connection on the one hand with the rods 120 via a connecting element, consisting of one or more parts 145, 145A, movable in longitudinal translation, and on the other hand with the pusher 110.
  • This connecting element 145, 145A is more precisely linked to the central axis 125 of the rods 120.
  • the lever 143 is mounted in rotation on two moving parts in rotation relative to the base 130, the front support 140 at the front, connected to the base, and the intermediate piece 144 at the rear, connected to the jaws.
  • These three parts 143, 140, 144 are interconnected by a common axis of rotation, the axis of rotation 142 of the lever 143.
  • the cover 150 covers the rods and partially the pusher, and has an opening in its front part for the passage of the actuating device, in particular the lever. It also includes side walls protecting the side parts of the actuating device and the trigger mechanism.
  • the lever 143 In the fitting configuration of the stop, the lever 143 is turned down as far as possible, towards the front of the stop, around its axis of rotation 142. It reaches a substantially horizontal positioning. This actuation also has the effect of causing the rear support 140 to rotate backwards and the axis of rotation 142 of the lever 143 to be positioned in the low and withdrawn position. As a result, the connecting element 145, 145A is pushed back, through the intermediate piece 144, and therefore pushes back the central axis 125 of the rods 120 and the pusher 110 to reach the fitting configuration described above. In this configuration, the trigger spring 112, which is compressed, exerts a restoring force against the actuating device. This first position of the lever 143 in the boot configuration is maintained by a permanent support on the lever 143, for example by means of a stick.
  • the lever In the lowering configuration of the stop, the lever is in an intermediate raised position. This position is easily reached by the elastic return exerted on the actuating device due to the toggle type construction when the skier releases the pressure on the lever 143. In this configuration, the pressure on the central axis 125 of the rods 120 is released and the pusher 110 and rod 120 assembly returns to a position in which the trigger spring 112 is not or less compressed. In this configuration, the jaws 101 are maintained in their shoe holding position, under the effect of the pusher, and the triggering function described above is active.
  • the second position of the lever is a stable position. Note, this position depends on the width of the shoe, since the actuating device is also configured to adapt to different shoe widths.
  • the rise configuration is reached by tilting the lever 143 rearward, according to manual actuation or by means of a stick, until a substantially vertical position is reached.
  • the lever 143 comprises at least one finger 146 towards its lower end, opposite its gripping zone, more precisely two lateral fingers in this embodiment, which comes to cooperate with a notched surface 138 of the base or in a variant not shown of the cover, or alternatively of the pusher, as represented by the alternative embodiment of the figure 17 .
  • This cooperation ensures the maintenance of the lever in this third position, and the stability of the rise configuration, the movement of the axis of rotation 142, and of the entire actuating device, being blocked.
  • the choice of notch also corresponds to an adjustment of a certain spacing of the jaws.
  • the lever 143 exerts a force on the central axis 125 of the rods, by means of the connecting element 145, 145A and of the intermediate piece 144.
  • This force is sufficient to prevent any translation of the pusher 110 and movement of the rods 120 under the effect of forces from the shoe on the jaws.
  • the trigger function is thus locked and inactive.
  • this effort also positions the jaws according to a certain chosen spacing, as a function of the notch of the notched surface 138, which allows the stop to be adapted for use with shoes of different format, in particular of different width. Note, the device actuation is in a stable position in this rise configuration.
  • the actuation device described above has the advantage of being able to occupy three configurations corresponding to three positions of the lever, which alone allows it to determine one of the three configurations of the stop. There is no need for a separate lock or separate actuator.
  • the mobile support 140, the lever 143 and the intermediate piece 144, connected together at the level of an axis of rotation 142 of the lever 143 forms a toggle-type assembly, which makes it possible to reach the different positions mentioned above.
  • the axis of rotation 142 is movable relative to the base 130 of the stop. This assembly forming the actuating device is subjected to the energy of the trigger release spring, in particular in its operation according to the toggle mechanism.

  • This actuation device could include several separate actuators, for example a lever for two positions and an additional lock to deactivate the tripping function during the ascent phase.
  • this actuation device could act differently on the mechanism of the stop, on the rods and / or the pusher, or even directly on the jaws.

  • the link 16 comprises two link arms 28, 29, which we will alternatively more simply call “links”, connected together via a link link 27.
  • These link arms 28, 29 are arranged between the attachment points for links - jaws 14 , 15 so that they can transmit a pushing force with a component extending transversely to the line connecting the hooking points 14, 15.
  • the link 16 consists of two link arms 28, 29 connected to a link rod 27, the rod 16 thus acts as a one-piece bar transmitting the pushing force. This is essentially achieved by the fact that the link arms 28, 29 comprise, in addition to the link link 27, a bearing surface 30, 31 at the level of which the link arms 28, 29 rest against each other. other.

  • a spring element 39 pulls the piston 33 at the level of which the spacer key 6 is arranged with its bearing surfaces 7 above the point of rotation 43, between the cams 32 and 34, in the direction F, and thus maintains the link arms 28, 29 stretched at the stop 30/31.
  • a device 41 on the upper side of the ski binding when it is strongly stressed by the end of the ski boot, can bear a lever or a push button 42 against the link 16. This folds the link in the form of V and thus reduces the spacing between the attachment points 14, 15 so as to be able to spread the ends of the jaws 17, 18 at the level of which the holding pins 19, 20 can be disposed and release the ski boot.
  • an advantage of the solution comes from the attachment points of the jaws connected to each other via a link. This has the consequence that the jaws are not moved independently of each other, but that a displacement of one jaw necessarily results in a movement of the other jaw. This makes it possible to fix the ski binding so that a shoe hooked in the ski binding can have a certain play of movement without detaching from the binding. It is only when a predefined clearance is exceeded that the jaws release the ski boot.
  • the link can slide on a line connecting the attachment points for links - jaws.
  • the link can thus slide, for example relative to a base plate or relative to the ski on which the ski binding is arranged. With axes of rotation of the fixed jaws, such sliding on a line between the connecting points for connecting rods - jaws causes a sliding of the jaw position and thus a movement of the ski boot hooked in the ski binding.
  • the jaws comprise a hooking arm extending from the axis of rotation of the jaws at the connecting point for connecting rods - jaws and a holding arm extending from the axis of rotation of the jaws to a holding pin. This allows a ski boot to be hung between two holding pins of two jaws by introducing the holding pins into the corresponding recesses at the end of the ski boot.
  • the link comprises two link arms connected to each other via a link link. This makes it possible to fold the link and thus reduce the spacing between the attachment points to separate the ends of the jaws at the level of which holding pins can be arranged.
  • a link link makes it more difficult to transmit a pushing force towards the link.

Description

L'invention concerne une butée d'un dispositif de fixation d'une chaussure sur une planche de glisse. Cette butée est particulièrement adaptée au ski de randonnée. Elle concerne aussi un dispositif de fixation d'une chaussure sur une planche de glisse et une planche de glisse en tant que telle équipée d'un tel dispositif de fixation et/ou d'une telle butée. Le document EP-A1-2353673 décrit une butée d'un dispositif de fixation d'une chaussure sur un ski de randonnée. La fixation avant de la chaussure repose sur deux mâchoires de la butée articulées selon des axes de pivotement longitudinaux par rapport à une embase de la butée destinée à être fixée sur le ski de randonnée. Chaque mâchoire comprend des éléments de retenue destinés à coopérer avec la chaussure de ski de randonnée. Les deux mâchoires sont articulées par un système de ressort afin d'occuper une première position stable dite fermée dans laquelle les éléments de retenue coopèrent avec des parties creuses correspondantes aménagées latéralement dans la partie antérieure de la chaussure de ski de randonnée, afin de fixer la chaussure en autorisant uniquement son mouvement de rotation autour d'un axe transverse au ski, et une seconde position stable dite ouverte dans laquelle les mâchoires sont écartées de sorte que les éléments de retenue libèrent la chaussure qui peut être séparée du ski de randonnée. La fixation de la partie avant de la chaussure sur un ski de randonnée équipé d'une telle butée est réalisée en positionnant la chaussure alors que les deux mâchoires occupent la seconde position ouverte, puis en appuyant fortement avec la semelle de la chaussure sur le système à base de ressort qui permet le passage des mâchoires articulées vers leur première position fermée dans laquelle elles se rapprochent de la chaussure afin de positionner les éléments de retenue au sein de parties creuses complémentaires de la chaussure.The invention relates to a stop for a device for fixing a shoe on a gliding board. This stop is particularly suitable for ski touring. It also relates to a device for fixing a shoe on a sliding board and a sliding board as such equipped with such a fixing device and / or such a stop. The document EP-A1-2353673 describes a stop of a device for fixing a boot on a ski touring. The front binding of the boot rests on two jaws of the stop articulated along longitudinal pivot axes relative to a base of the stop intended to be fixed on the ski touring. Each jaw comprises retaining elements intended to cooperate with the ski touring boot. The two jaws are articulated by a spring system in order to occupy a first stable position known as closed in which the retaining elements cooperate with corresponding hollow parts arranged laterally in the front part of the ski touring boot, in order to fix the boot allowing only its rotational movement about an axis transverse to the ski, and a second stable position called open in which the jaws are separated so that the retaining elements release the boot which can be separated from the ski touring. The front part of the boot is attached to a ski touring ski equipped with such a stopper is positioned by positioning the boot while the two jaws occupy the second open position, then pressing strongly with the sole of the boot on the system spring-based which allows the passage of the articulated jaws towards their first closed position in which they approach the shoe in order to position the retaining elements within complementary hollow parts of the shoe.

Le document FR-A-2656806 décrit une butée selon le préambule de la revendication 1. Cette butée comprend, en outre, deux biellettes reliées chacune à une mâchoire par un axe latéral et reliées entre elles par un axe central, et un poussoir.The document FR-A-2656806 describes a stop according to the preamble of claim 1. This stop further comprises two rods each connected to a jaw by a lateral axis and connected to each other by a central axis, and a pusher.

Le document EP-A1-2626116 décrit un butée d'un dispositif de fixation d'une chaussure sur un ski, comprenant un poussoir qui comporte deux surfaces de déclenchement latérales coopérant chacune avec une rampe respective de chaque mâchoire, ce poussoir étant relié à l'embase par un ressort de déclenchement qui permet de contrôler son déplacement.The document EP-A1-2626116 describes a stop for a device for attaching a boot to a ski, comprising a pusher which has two lateral trigger surfaces each cooperating with a respective ramp of each jaw, this pusher being connected to the base by a trigger spring which makes it possible to control its movement.

Un inconvénient de telles butées existantes est leur manque de sécurité dans le cas d'une chute du skieur, notamment dans le cas d'une chute en torsion du skieur dans une situation en descente de type ski alpin, impliquant un mouvement de torsion de la chaussure par rapport au ski durant lequel la chaussure reste prisonnière de la butée, ce qui risque d'induire des blessures du skieur.A drawback of such existing stops is their lack of security in the event of a fall of the skier, in particular in the case of a torsional fall of the skier in a downhill situation of the alpine ski type, implying a torsional movement of the boot relative to the ski during which the boot remains trapped in the stop, which risks inducing injuries to the skier.

Plus généralement, outre leur manque de sécurité, les butées de l'état de la technique présentent de nombreux autres inconvénients, parmi lesquels le fait d'être difficiles à manœuvrer, donc peu conviviales, d'être complexes, encombrantes et/ou lourdes.More generally, in addition to their lack of security, the stops of the state of the art have many other drawbacks, among which the fact of being difficult to maneuver, therefore not very user-friendly, of being complex, bulky and / or heavy.

Le but de la présente invention est de proposer une solution de fixation d'une chaussure sur une planche de glisse qui remédie aux inconvénients listés ci-dessus.The purpose of the present invention is to provide a solution for fixing a shoe on a gliding board which overcomes the drawbacks listed above.

Un premier objet de la présente invention est de fournir une solution de fixation d'une chaussure sur une planche de glisse, notamment sur un ski de randonnée, garantissant une sécurité optimale au skieur en cas de chute.A first object of the present invention is to provide a solution for fixing a shoe on a gliding board, in particular on a ski touring, guaranteeing optimum safety for the skier in the event of a fall.

Un deuxième objet de la présente invention est de fournir une solution de fixation d'une chaussure simple, facile à manœuvrer, peu encombrante, économique et légère.A second object of the present invention is to provide a solution for fixing a shoe that is simple, easy to maneuver, compact, economical and light.

Ces buts peuvent être atteints par l'intermédiaire d'une butée pour dispositif de fixation d'une chaussure sur une planche de glisse, comprenant une embase destinée à être fixée sur la planche de glisse, et caractérisée en ce qu'elle comprend deux mâchoires latérales, montées chacune mobile en rotation sur l'embase de sorte à pouvoir occuper une position fermée dans laquelle elles sont aptes au maintien d'une chaussure sur une planche de glisse et une position écartée dans laquelle elles sont aptes à recevoir une chaussure, un poussoir comprenant une surface de déclenchement coopérant avec une rampe de chaque mâchoire, ce poussoir étant relié à l'embase par un ressort de déclenchement qui permet de contrôler son déplacement, et deux biellettes reliées entre elles et reliées chacune à une mâchoire.These aims can be achieved by means of a stop for a device for fixing a boot on a gliding board, comprising a base intended to be fixed on the gliding board, and characterized in that it comprises two jaws lateral, each mounted mobile in rotation on the base so as to be able to occupy a closed position in which they are capable of holding a shoe on a gliding board and a spread position in which they are capable of receiving a shoe, a pusher comprising a trigger surface cooperating with a ramp of each jaw, this pusher being connected to the base by a trigger spring which makes it possible to control its movement, and two rods connected together and each connected to a jaw.

La description suivante concerne une butée ou élément de fixation avant d'un dispositif de fixation d'une chaussure sur une planche de glisse (non représentée). Cette butée assure la fixation de la partie avant de la chaussure et est particulièrement adaptée à la pratique du ski de randonnée, mais n'exclut pas une utilisation dans le cadre du ski alpin et/ou du ski de fond. De manière plus générale, la butée participe à la constitution du dispositif de fixation de la chaussure sur la planche de glisse, en combinaison avec une talonnière arrière (non représentée) assurant optionnellement la fixation de la partie arrière de la chaussure.The following description relates to a stop or front fixing element of a device for fixing a boot on a gliding board (not shown). This stopper secures the front part of the boot and is particularly suitable for the practice of ski touring, but does not exclude use in the context of alpine skiing and / or cross-country skiing. More generally, the stop participates in the constitution of the device for fixing the boot on the gliding board, in combination with a rear heel piece (not shown) optionally ensuring the fixing of the rear part of the boot.

Les figures 1 à 17 illustrent un premier mode de réalisation d'une telle butée. Les figures 18 à 26 illustrent un deuxième mode de réalisation d'une telle butée.The Figures 1 to 17 illustrate a first embodiment of such a stop. The Figures 18 to 26 illustrate a second embodiment of such a stop.

Pour faciliter la compréhension de la suite de la description, un repère orthonormé est associé à la butée, la direction longitudinale X de la butée étant la direction horizontale, orientée de l'arrière vers l'avant de la butée, cette direction longitudinale correspondant par ailleurs à la direction de l'arrière vers l'avant d'un ski sur lequel la butée est destinée à être disposée. La direction transversale Y correspond à la direction horizontale perpendiculaire à la direction X et orientée de la droite vers la gauche. Le plan horizontal correspond ainsi à un plan parallèle à la surface d'un ski sur lequel la butée est destinée à être disposée. La direction verticale Z est perpendiculaire au plan horizontal défini par les directions X et Y et est orientée vers le haut.To make it easier to understand the rest of the description, an orthonormal coordinate system is associated with the stop, the longitudinal direction X of the stop being the horizontal direction, oriented from the rear towards the front of the stop, this longitudinal direction corresponding by elsewhere in the direction from the rear to the front of a ski on which the stop is intended to be arranged. The transverse direction Y corresponds to the horizontal direction perpendicular to the X direction and oriented from right to left. The horizontal plane thus corresponds to a plane parallel to the surface of a ski on which the stop is intended to be placed. The vertical direction Z is perpendicular to the horizontal plane defined by the X and Y directions and is oriented upwards.

La butée selon les modes de réalisation de l'invention est sensiblement symétriquement agencée par rapport à un plan médian longitudinal vertical, et nous décrirons parfois en détail un seul côté de la butée, le deuxième opposé étant similaire car symétrique.The stop according to the embodiments of the invention is substantially symmetrically arranged with respect to a vertical longitudinal median plane, and we will sometimes describe in detail only one side of the stop, the second opposite being similar because it is symmetrical.

Selon le premier mode de réalisation, la butée comprend une embase 130 destinée à être fixée sur une planche de glisse, et des éléments mobiles agencés sur cette embase 130. Elle comprend également un capot 150 supérieur positionné en avant des mâchoires et recouvrant tout ou partie des éléments mobiles. Elle comprend de plus un logement 137 sensiblement cylindrique en partie arrière, prévu pour la réception d'un axe de liaison d'une chaussure, non représentée.According to the first embodiment, the stop comprises a base 130 intended to be fixed on a gliding board, and mobile elements arranged on this base 130. It also comprises an upper cover 150 positioned in front of the jaws and covering all or part moving parts. It further comprises a housing 137 substantially cylindrical in the rear part, provided for the reception of a connecting axis of a shoe, not shown.

La butée comprend d'abord deux mâchoires rigides 101, agencées latéralement et en partie arrière de la butée. Chaque mâchoire 101 comprend un élément de retenue 102 destiné à assurer la retenue de la chaussure lorsque la mâchoire est dans une position fermée, qui sera détaillée plus loin. L'élément de retenue 102 se présente sous la forme d'un picot de maintien destiné à s'engager dans des ouvertures latérales ménagées dans la partie avant de la chaussure. Il est ainsi orienté vers le centre de la butée, dans une direction sensiblement transversale. Chaque mâchoire s'étend sensiblement longitudinalement de chaque côté de la butée, de sorte à pouvoir coopérer avec les deux surfaces latérales d'une chaussure.The stop first comprises two rigid jaws 101, arranged laterally and in the rear part of the stop. Each jaw 101 comprises a retaining element 102 intended to ensure the retention of the shoe when the jaw is in a closed position, which will be detailed below. The retaining element 102 is in the form of a retaining pin intended to engage in lateral openings formed in the front part of the shoe. It is thus oriented towards the center of the stop, in a substantially transverse direction. Each jaw extends substantially longitudinally on each side of the stop, so as to be able to cooperate with the two lateral surfaces of a shoe.

Chaque mâchoire 101 est montée à pivotement relativement à la butée, plus précisément relativement à l'embase 130, autour d'un axe de rotation 103 sensiblement vertical. L'élément de retenue 102 est positionné en partie arrière et supérieure de la mâchoire, notamment à l'arrière de l'axe de rotation 103 de la mâchoire. Il en résulte que chaque élément de retenue 102 peut être écarté vers l'extérieur par rotation de la mâchoire 101, permettant ainsi le chaussage et le déchaussage d'une chaussure. Naturellement, chaque mâchoire 101 peut occuper une position de fermeture dans laquelle ses éléments de retenue 102 sont aptes à maintenir une chaussure de ski. Un ressort de rappel exerce un effort sur la mâchoire tendant à la maintenir dans sa position de fermeture. Selon ce mode de réalisation, ce ressort de rappel est un ressort de déclenchement 112 qui sera décrit ci-dessous. De plus, chaque mâchoire 101 comprend des ailettes 105 de renforcement, pour leur permettre de subir des contraintes élevées sans risque. Ces ailettes s'étendent dans un plan sensiblement horizontal XY. Elles sont suffisamment larges et coulissent dans des rainures latérales d'un poussoir 110 qui sera décrit ci-après.Each jaw 101 is pivotally mounted relative to the stop, more precisely relative to the base 130, about a substantially vertical axis of rotation 103. The retaining element 102 is positioned in the rear and upper part of the jaw, in particular behind the axis of rotation 103 of the jaw. As a result, each retaining element 102 can be moved outward by rotation of the jaw 101, thus allowing the shoe to be put on and taken off. Naturally, each jaw 101 can occupy a closed position in which its retaining elements 102 are capable of holding a ski boot. A return spring exerts a force on the jaw tending to keep it in its closed position. According to this embodiment, this return spring is a trigger spring 112 which will be described below. In addition, each jaw 101 includes reinforcing fins 105, to allow them to undergo high stresses without risk. These fins extend in a substantially horizontal plane XY. They are sufficiently wide and slide in lateral grooves of a pusher 110 which will be described below.

Chaque mâchoire 101 comprend aussi une partie particulière agencée autour de l'axe de rotation 103, orientée vers l'intérieur de la butée, dont une extrémité forme une surface arrière sensiblement verticale formant une rampe 104 destinée à coopérer avec une surface de déclenchement 114 d'un poussoir 110, selon un fonctionnement qui sera détaillé par la suite. Cette rampe 104 est disposée à l'arrière de l'axe de rotation 103 de la mâchoire 101.Each jaw 101 also includes a particular part arranged around the axis of rotation 103, oriented towards the inside of the stop, of which one end forms a substantially vertical rear surface forming a ramp 104 intended to cooperate with a trigger surface 114 of a pusher 110, according to an operation which will be detailed later. This ramp 104 is arranged at the rear of the axis of rotation 103 of the jaw 101.

Cette partie particulière agencée autour de l'axe de rotation 103 de chaque mâchoire 101 comprend de plus une extrémité frontale, positionnée en avant de l'axe de rotation 103, supportant une biellette 120 par un axe latéral 123.This particular part arranged around the axis of rotation 103 of each jaw 101 further comprises a front end, positioned in front of the axis of rotation 103, supporting a link 120 by a lateral axis 123.

Ainsi, chaque mâchoire 101 supporte une biellette 120 par un axe latéral 123. La butée comprend donc deux biellettes 120. Ces deux biellettes 120 s'étendent dans une direction sensiblement transversale, variable angulairement selon la configuration de la butée, et sont articulées entre elles par un axe central 125 disposé en partie centrale de la butée. Un tel axe central 125 est libre de se déplacer relativement à l'embase 130 de la butée. Cet axe central 125 est solidaire d'un poussoir 110 et son déplacement est guidé par le poussoir 110 de sorte qu'il s'agit d'un déplacement en translation longitudinale.Thus, each jaw 101 supports a link 120 by a lateral axis 123. The stop therefore comprises two links 120. These two links 120 extend in a substantially transverse direction, angularly variable according to the configuration of the stop, and are hinged together by a central axis 125 disposed in the central part of the stop. Such a central axis 125 is free to move relative to the base 130 of the stop. This central axis 125 is integral with a pusher 110 and its movement is guided by the pusher 110 so that it is a displacement in longitudinal translation.

Enfin, comme évoqué précédemment, la butée comprend un poussoir 110, mobile en translation longitudinale. Pour guider et fiabiliser ce déplacement du poussoir 110, ce dernier comprend une glissière centrale longitudinale dans laquelle est positionné un (ou plusieurs) plot 131 fixé sur l'embase 130 de la butée. Le poussoir est soumis à l'effort d'un ressort de déclenchement 112, s'étendant longitudinalement dans une partie centrale de la butée, et dont une extrémité arrière est fixée à une butée arrière 132 de l'embase 130 et une extrémité avant est fixée sur le poussoir 110. Ce dernier comprend de plus deux surfaces de déclenchement 114 latérales, destinées à coopérer avec les rampes 104 des mâchoires 101. Ces surfaces de déclenchement 114 sont agencées en surface avant de doigts latéraux du poussoir 110 ; ces doigts s'étendent transversalement avec une inclinaison vers l'avant. L'effort exercé par le ressort de déclenchement 112 est réglable en déplaçant la butée arrière 132 par l'intermédiaire d'une vis de réglage 133, agencée en surface frontale de la butée.Finally, as mentioned above, the stop comprises a pusher 110, movable in longitudinal translation. To guide and make this movement of the pusher 110 more reliable, the latter comprises a longitudinal central slide in which is positioned one (or more) stud 131 fixed on the base 130 of the stop. The pusher is subjected to the force of a trigger spring 112, extending longitudinally in a central part of the stop, and of which a rear end is fixed to a rear stop 132 of the base 130 and a front end is fixed on the pusher 110. The latter further comprises two lateral trigger surfaces 114, intended to cooperate with the ramps 104 jaws 101. These trigger surfaces 114 are arranged on the front surface of lateral fingers of the pusher 110; these fingers extend transversely with a forward inclination. The force exerted by the trigger spring 112 is adjustable by moving the rear stop 132 by means of an adjustment screw 133, arranged on the front surface of the stop.

Le fonctionnement de la butée va maintenant être explicité. Elle peut occuper trois configurations principales, dites de chaussage, de montée et de descente ou de ski.The operation of the stop will now be explained. It can occupy three main configurations, known as footwear, ascent and descent or skiing.

Les figures 4 à 7 illustrent la butée en configuration de chaussage. Dans cette position, l'axe central 125 des biellettes 120 est positionné dans une position arrière, par un dispositif d'actionnement qui sera détaillé par la suite. Dans cette position, l'axe central 125 vient presque dans l'alignement transversal des deux axes de rotation 103 des mâchoires 101. Cette position reculée des biellettes induit une traction vers le centre sur chaque axe latéral 123 des biellettes, qui exerce en conséquence un couple de rotation sur les mâchoires 101, et entraine les mâchoires 101 en rotation vers l'extérieur de la butée. Ceci permet de libérer un espace central entre les deux éléments de retenue 102 pour permettre le positionnement d'une chaussure de ski dans une opération de chaussage de la butée, ou le retrait d'une chaussure dans une opération de déchaussage. Dans cette opération, chacune des mâchoires 101 est écartée vers l'extérieur d'un angle compris entre 8 et 15 degrés inclus environ.The figures 4 to 7 illustrate the stopper in the boot configuration. In this position, the central axis 125 of the rods 120 is positioned in a rear position, by an actuating device which will be detailed later. In this position, the central axis 125 comes almost in the transverse alignment of the two axes of rotation 103 of the jaws 101. This retracted position of the rods induces a traction towards the center on each lateral axis 123 of the rods, which consequently exerts a torque on the jaws 101, and causes the jaws 101 to rotate towards the outside of the stop. This frees up a central space between the two retaining elements 102 to allow the positioning of a ski boot in a boot fitting operation, or the removal of a boot in a heaving operation. In this operation, each of the jaws 101 is spread outwards by an angle of between 8 and 15 degrees inclusive approximately.

En remarque, dans cette configuration de chaussage de la butée, le poussoir 110 est de même positionné dans une position reculée, dans laquelle le ressort de déclenchement 112 est légèrement comprimé.Note, in this configuration of fitting the stop, the pusher 110 is likewise positioned in a retracted position, in which the trigger spring 112 is slightly compressed.

Lorsque la chaussure est positionnée dans la butée en configuration de chaussage, l'actionnement de la butée est relâché par le dispositif d'actionnement qui sera décrit ci-après, de sorte que le poussoir 110 retrouve sa position de repos plus avancé sous l'effet du ressort de déclenchement 112, rappelant les mâchoires 101 en rotation jusqu'à leur position fermée et l'axe central 125 des biellettes 120 en position avant, jusqu'à atteindre la configuration de descente, représentée par les figures 9 à 11, dans laquelle les éléments de retenue 102 sont emboités dans des évidements d'une chaussure, non représentée, pour la maintenir.When the shoe is positioned in the stopper in the boot configuration, the actuation of the stopper is released by the actuation device which will be described below, so that the pusher 110 returns to its more advanced rest position under the effect of the trigger spring 112, recalling the jaws 101 in rotation to their closed position and the central axis 125 of the rods 120 in the front position, until reaching the descent configuration, represented by the figures 9 to 11 , wherein the retaining elements 102 are fitted into recesses of a shoe, not shown, to hold it.

Dans cette configuration de descente, les mâchoires 101 sont maintenues fermées de sorte à garantir le maintien d'une chaussure, non représentée. Toutefois, si un effort latéral est exercé par la chaussure sur une mâchoire, notamment lors d'une torsion de la chaussure, la mâchoire possède un degré de liberté en rotation autour de son axe de rotation 103 et peut accompagner légèrement la chaussure dans un déplacement de torsion vers l'extérieur. Un tel mouvement d'une mâchoire implique un déplacement semblable et simultané de la deuxième mâchoire 101 vers l'intérieur par l'intermédiaire des biellettes 120 qui lient les deux mâchoires. Par ce mécanisme à biellettes, les deux mâchoires possèdent une certaine liberté de rotation qui leur permet d'accompagner légèrement la chaussure dans ses pressions latérales, selon un angle maximal d'environ 20 degrés, dans une course élastique de la butée, avec un rappel élastique vers le recentrage des mâchoires.In this descent configuration, the jaws 101 are kept closed so as to guarantee the maintenance of a shoe, not shown. However, if a lateral force is exerted by the shoe on a jaw, in particular during a twisting of the shoe, the jaw has a degree of freedom in rotation around its axis of rotation 103 and can slightly accompany the shoe in a movement outwardly twisting. Such movement of a jaw implies a similar and simultaneous movement of the second jaw 101 inwardly via the rods 120 which connect the two jaws. By this link mechanism, the two jaws have a certain freedom of rotation which allows them to slightly accompany the shoe in its lateral pressures, at a maximum angle of about 20 degrees, in an elastic stroke of the stop, with a reminder elastic towards the centering of the jaws.

Une telle butée met de plus avantageusement en œuvre une fonction de déclenchement, qui assure ainsi une fonction essentielle de sécurité. En effet, lorsque la chaussure exerce un effort de torsion sur une mâchoire, cette dernière peut tourner autour de son axe de rotation 103, comme évoqué ci-dessus. Une telle rotation entraîne un déplacement relatif de la rampe 104 de la mâchoire relativement à la surface de déclenchement 114 du poussoir 110. Cette coopération des deux surfaces est telle que le poussoir est déplacé vers l'arrière, à l'encontre du ressort de déclenchement 112. Lorsque l'effort exercé par une chaussure est important, notamment lors d'une chute, il dépasse un seuil au-delà duquel la rampe 104 de la mâchoire se déplace sur toute la longueur de la surface de déclenchement 114, à l'encontre de l'effort contraire exercé par le ressort de déclenchement 112, jusqu'à dépasser un point A particulier sur la surface de déclenchement 114 et lui échapper, auquel cas la mâchoire 101 est alors libre de poursuivre son mouvement de rotation avec peu de retenue, permettant la libération de la chaussure. Le glissement relatif de la rampe 104 de la mâchoire relativement à la surface de déclenchement 114 du poussoir permet de définir une course élastique jusqu'au point A. Au-delà de ce point A, la mâchoire s'ouvre totalement vers l'extérieur, selon un angle supérieur à 20 degrés, permettant l'échappement d'une chaussure.Such a stop also advantageously implements a triggering function, which thus provides an essential safety function. In fact, when the shoe exerts a torsional force on a jaw, the latter can rotate around its axis of rotation 103, as mentioned above. Such a rotation causes a relative displacement of the ramp 104 of the jaw relative to the trigger surface 114 of the pusher 110. This cooperation of the two surfaces is such that the pusher is moved towards the rear, against the trigger spring 112. When the force exerted by a shoe is high, in particular during a fall, it exceeds a threshold beyond which the ramp 104 of the jaw moves over the entire length of the trigger surface 114, against the opposite force exerted by the trigger spring 112, until it exceeds a point Particularly on the trigger surface 114 and escape it, in which case the jaw 101 is then free to continue its rotational movement with little restraint, allowing the shoe to be released. The relative sliding of the ramp 104 of the jaw relative to the trigger surface 114 of the pusher makes it possible to define an elastic stroke up to point A. Beyond this point A, the jaw opens completely outwards, at an angle greater than 20 degrees, allowing the escape of a shoe.

Dans la mise en œuvre de cette fonction, il apparaît donc que la combinaison des formes de la rampe et de la surface de déclenchement, en coopération avec l'effort réglable exercé par le ressort de déclenchement 102, permet de définir le seuil de déclenchement optimal pour garantir la sécurité du skieur. Les deux surfaces complémentaires, la rampe de la mâchoire et la surface de déclenchement du poussoir, qui glissent l'une contre l'autre, sont donc conformées pour remplir au mieux la fonction de déclenchement.In implementing this function, it therefore appears that the combination of the shapes of the ramp and the trigger surface, in cooperation with the adjustable force exerted by the trigger spring 102, makes it possible to define the optimal trigger threshold to guarantee the safety of the skier. The two complementary surfaces, the jaw ramp and the trigger surface of the pusher, which slide against each other, are therefore shaped to best fulfill the trigger function.

Enfin, la butée peut être positionnée dans une troisième configuration dite de montée, dans laquelle la chaussure est maintenue par les mâchoires de manière verrouillée, c'est-à-dire dans laquelle le déclenchement n'est pas possible, est inactif. Il est en effet important d'empêcher tout déclenchement de la butée dans une phase de montée, pour garantir la sécurité du skieur à la montée, empêchant particulièrement la perte d'un ski. Cette configuration de montée est représentée par les figures 12 à 17.Finally, the stop can be positioned in a third so-called ascent configuration, in which the shoe is held by the jaws in a locked manner, that is to say in which tripping is not possible, is inactive. It is indeed important to prevent any triggering of the stop in a climbing phase, to guarantee the safety of the skier when climbing, preventing especially the loss of a ski. This climb configuration is represented by the Figures 12 to 17 .

Selon le mode de réalisation de l'invention, la butée est de plus actionnée par un dispositif d'actionnement avantageux qui va maintenant être décrit, et qui est particulièrement visible sur les figures 6, 10, 14 et 15.According to the embodiment of the invention, the stop is further actuated by an advantageous actuation device which will now be described, and which is particularly visible on the figures 6 , 10 , 14 and 15 .

Ce dispositif d'actionnement comprend un support frontal 140 monté mobile en rotation dans sa partie avant inférieure relativement à l'embase 130 de la butée, autour d'un axe transversale 141, notamment représenté sur les figures 2 et 12. Il porte un deuxième axe dans sa deuxième extrémité arrière supérieure, qui forme un axe de rotation 142 pour un levier 143. En effet, un levier 143 comprenant une zone de préhension pour sa manipulation aisée par un utilisateur est monté mobile en rotation autour de cet axe de rotation 142 sensiblement transversal ; il est de plus sollicité par un ressort de rappel optionnel disposé autour de cet axe de rotation 142. Le dispositif d'actionnement comprend de plus une pièce intermédiaire 144 dont une extrémité avant est fixée au support frontal 140 et/ou au levier 143 au niveau de l'axe de rotation 142 du levier. Cette pièce intermédiaire 144 comprend enfin une liaison d'une part avec les biellettes 120 par l'intermédiaire d'un élément de liaison, constitué d'une ou de plusieurs pièces 145, 145A, mobile en translation longitudinale, et d'autre part avec le poussoir 110. Cet élément de liaison 145, 145A est plus précisément lié à l'axe central 125 des biellettes 120. Autrement dit, le levier 143 est monté en rotation sur deux pièces mobiles en rotation par rapport à l'embase 130, le support frontal 140 à l'avant, relié à l'embase, et la pièce intermédiaire 144 à l'arrière, reliée aux mâchoires. Ces trois pièces 143, 140, 144 sont reliées entre elles par un axe commun de rotation, l'axe de rotation 142 du levier 143.This actuating device comprises a front support 140 mounted movable in rotation in its lower front part relative to the base 130 of the stop, around a transverse axis 141, in particular shown on the figures 2 and 12 . It carries a second axis in its second upper rear end, which forms an axis of rotation 142 for a lever 143. In fact, a lever 143 comprising a gripping zone for its easy manipulation by a user is mounted so as to rotate about this axis of rotation 142 substantially transverse; it is further requested by an optional return spring disposed around this axis of rotation 142. The actuating device further comprises an intermediate piece 144 whose front end is fixed to the front support 140 and / or to the lever 143 at the level of the axis of rotation 142 of the lever. This intermediate piece 144 finally comprises a connection on the one hand with the rods 120 via a connecting element, consisting of one or more parts 145, 145A, movable in longitudinal translation, and on the other hand with the pusher 110. This connecting element 145, 145A is more precisely linked to the central axis 125 of the rods 120. In other words, the lever 143 is mounted in rotation on two moving parts in rotation relative to the base 130, the front support 140 at the front, connected to the base, and the intermediate piece 144 at the rear, connected to the jaws. These three parts 143, 140, 144 are interconnected by a common axis of rotation, the axis of rotation 142 of the lever 143.

Dans ce mode de réalisation, le capot 150 recouvre les biellettes et partiellement le poussoir, et présente une ouverture dans sa partie avant pour le passage du dispositif d'actionnement, notamment le levier. Il comprend également des parois latérales protégeant les parties latérales du dispositif d'actionnement et du mécanisme de déclenchement.In this embodiment, the cover 150 covers the rods and partially the pusher, and has an opening in its front part for the passage of the actuating device, in particular the lever. It also includes side walls protecting the side parts of the actuating device and the trigger mechanism.

Le fonctionnement de ce dispositif d'actionnement va maintenant être explicité.The operation of this actuating device will now be explained.

Dans la configuration de chaussage de la butée, le levier 143 est tourné au maximum vers le bas, en direction vers l'avant de la butée, autour de son axe de rotation 142. Il atteint un positionnement sensiblement horizontal. Cet actionnement a aussi pour effet d'entraîner la rotation vers l'arrière du support frontal 140 et le positionnement en position basse et reculée de l'axe de rotation 142 du levier 143. Il en résulte que l'élément de liaison 145, 145A est poussé vers l'arrière, par l'intermédiaire de la pièce intermédiaire 144, et repousse donc vers l'arrière l'axe central 125 des biellettes 120 et du poussoir 110 pour atteindre la configuration de chaussage décrite précédemment. Dans cette configuration, le ressort de déclenchement 112, qui est comprimé, exerce un effort de rappel à l'encontre du dispositif d'actionnement. Cette première position du levier 143 en configuration de chaussage est maintenue par un appui permanent sur le levier 143, par exemple par l'intermédiaire d'un bâton.In the fitting configuration of the stop, the lever 143 is turned down as far as possible, towards the front of the stop, around its axis of rotation 142. It reaches a substantially horizontal positioning. This actuation also has the effect of causing the rear support 140 to rotate backwards and the axis of rotation 142 of the lever 143 to be positioned in the low and withdrawn position. As a result, the connecting element 145, 145A is pushed back, through the intermediate piece 144, and therefore pushes back the central axis 125 of the rods 120 and the pusher 110 to reach the fitting configuration described above. In this configuration, the trigger spring 112, which is compressed, exerts a restoring force against the actuating device. This first position of the lever 143 in the boot configuration is maintained by a permanent support on the lever 143, for example by means of a stick.

Dans la configuration de descente de la butée, le levier est dans une position intermédiaire relevée. Cette position est atteinte facilement par le rappel élastique exercé sur le dispositif d'actionnement du fait de la construction de type genouillère lorsque le skieur relâche la pression sur le levier 143. Dans cette configuration, la pression sur l'axe central 125 des biellettes 120 est relâché et l'ensemble poussoir 110 et biellettes 120 retrouve une position dans laquelle le ressort de déclenchement 112 est pas ou moins comprimé. Dans cette configuration, les mâchoires 101 sont maintenues dans leur position de maintien d'une chaussure, sous l'effet du poussoir, et la fonction de déclenchement décrite précédemment est active. La deuxième position du levier est une position stable. En remarque, cette position dépend de la largeur de la chaussure, puisque le dispositif d'actionnement est aussi configuré pour s'adapter à différentes largeurs de chaussures.In the lowering configuration of the stop, the lever is in an intermediate raised position. This position is easily reached by the elastic return exerted on the actuating device due to the toggle type construction when the skier releases the pressure on the lever 143. In this configuration, the pressure on the central axis 125 of the rods 120 is released and the pusher 110 and rod 120 assembly returns to a position in which the trigger spring 112 is not or less compressed. In this configuration, the jaws 101 are maintained in their shoe holding position, under the effect of the pusher, and the triggering function described above is active. The second position of the lever is a stable position. Note, this position depends on the width of the shoe, since the actuating device is also configured to adapt to different shoe widths.

Enfin, la configuration de montée est atteinte par un basculement vers l'arrière du levier 143, selon un actionnement manuel ou par l'intermédiaire d'un bâton, jusqu'à atteindre une position sensiblement verticale. Comme cela est particulièrement visible sur la figure 15, le levier 143 comprend au moins un doigt 146 vers son extrémité inférieure, opposée à sa zone de préhension, plus précisément deux doigts latéraux dans ce mode de réalisation, qui vient coopérer avec une surface crantée 138 de l'embase ou en variante non représentée du capot, ou en variante du poussoir, comme représenté par la variante de réalisation de la figure 17. Cette coopération assure le maintien du levier dans cette troisième position, et la stabilité de la configuration de montée, le déplacement de l'axe de rotation 142, et de l'ensemble du dispositif d'actionnement, étant bloqué. Le choix du cran correspond de plus à un réglage d'un certain écartement des mâchoires. Dans cette position, le levier 143 exerce un effort sur l'axe central 125 des biellettes, par l'intermédiaire de l'élément de liaison 145, 145A et de la pièce intermédiaire 144. Cet effort est suffisant pour empêcher toute translation du poussoir 110 et mouvement des biellettes 120 sous l'effet d'efforts de la chaussure sur les mâchoires. La fonction de déclenchement est ainsi verrouillée et inactive. De plus, cet effort positionne aussi les mâchoires selon un certain écartement choisi, en fonction du cran de la surface crantée 138, ce qui permet à la butée d'être adaptée pour une utilisation avec des chaussures de format différent, notamment de largeur différente. En remarque, le dispositif d'actionnement est dans une position stable dans cette configuration de montée.Finally, the rise configuration is reached by tilting the lever 143 rearward, according to manual actuation or by means of a stick, until a substantially vertical position is reached. As is particularly visible on the figure 15 , the lever 143 comprises at least one finger 146 towards its lower end, opposite its gripping zone, more precisely two lateral fingers in this embodiment, which comes to cooperate with a notched surface 138 of the base or in a variant not shown of the cover, or alternatively of the pusher, as represented by the alternative embodiment of the figure 17 . This cooperation ensures the maintenance of the lever in this third position, and the stability of the rise configuration, the movement of the axis of rotation 142, and of the entire actuating device, being blocked. The choice of notch also corresponds to an adjustment of a certain spacing of the jaws. In this position, the lever 143 exerts a force on the central axis 125 of the rods, by means of the connecting element 145, 145A and of the intermediate piece 144. This force is sufficient to prevent any translation of the pusher 110 and movement of the rods 120 under the effect of forces from the shoe on the jaws. The trigger function is thus locked and inactive. In addition, this effort also positions the jaws according to a certain chosen spacing, as a function of the notch of the notched surface 138, which allows the stop to be adapted for use with shoes of different format, in particular of different width. Note, the device actuation is in a stable position in this rise configuration.

Ainsi, le dispositif d'actionnement décrit ci-dessus présente l'avantage de pouvoir occuper trois configurations correspondant à trois positions du levier, ce qui lui permet à lui seul de déterminer l'une des trois configurations de la butée. Il n'y a pas besoin d'un verrou ou d'un actionneur distinct complémentaire. En remarque, sa construction à trois éléments, le support mobile 140, le levier 143 et la pièce intermédiaire 144, reliés ensemble au niveau d'un axe de rotation 142 du levier 143, forme un ensemble de type genouillère, qui permet d'atteindre les différentes positions mentionnées précédemment. On note que dans cette construction, l'axe de rotation 142 est mobile relativement à l'embase 130 de la butée. Cet ensemble formant le dispositif d'actionnement est soumis à l'énergie du ressort de déclenchement de la butée, notamment dans son fonctionnement selon le mécanisme à genouillère.Thus, the actuation device described above has the advantage of being able to occupy three configurations corresponding to three positions of the lever, which alone allows it to determine one of the three configurations of the stop. There is no need for a separate lock or separate actuator. Note, its three-element construction, the mobile support 140, the lever 143 and the intermediate piece 144, connected together at the level of an axis of rotation 142 of the lever 143, forms a toggle-type assembly, which makes it possible to reach the different positions mentioned above. Note that in this construction, the axis of rotation 142 is movable relative to the base 130 of the stop. This assembly forming the actuating device is subjected to the energy of the trigger release spring, in particular in its operation according to the toggle mechanism.

Naturellement, l'invention ne se limite pas à la description précédente. Par exemple, un autre dispositif d'actionnement pourrait être disposé sur la butée pour le choix de sa configuration. Ce dispositif d'actionnement pourrait comprendre plusieurs actionneurs distincts, par exemple un levier pour deux positions et un verrou complémentaire pour désactiver la fonction de déclenchement en phase de montée. D'autre part, ce dispositif d'actionnement pourrait agir différemment sur le mécanisme de la butée, sur les biellettes et/ou le poussoir, voire directement sur les mâchoires.Naturally, the invention is not limited to the preceding description. For example, another actuating device could be placed on the stop for the choice of its configuration. This actuation device could include several separate actuators, for example a lever for two positions and an additional lock to deactivate the tripping function during the ascent phase. On the other hand, this actuation device could act differently on the mechanism of the stop, on the rods and / or the pusher, or even directly on the jaws.

De plus, les mâchoires pourraient coopérer avec un poussoir de forme différente et/ou mobile différemment, ayant par exemple un degré de liberté dans une direction transversale, et non uniquement longitudinale, voire être animé d'une rotation. De même, les biellettes pourraient présenter d'autres géométries et déplacements, et être actionnées différemment. Elles pourraient de plus être reliées au poussoir de manière indirecte, et non directement comme sur le mode de réalisation décrit.In addition, the jaws could cooperate with a pusher of different shape and / or mobile differently, having for example a degree of freedom in a transverse direction, and not only longitudinal, even be animated by a rotation. Similarly, the links could have other geometries and displacements, and be actuated differently. They could also be connected to the pusher indirectly, and not directly as in the embodiment described.

Les figures 18 à 27 illustrent un deuxième mode de réalisation de l'invention.The Figures 18 to 27 illustrate a second embodiment of the invention.

Pour accrocher la chaussure de ski (non représentée), deux mâchoires 8, 9 sont prévues, ces mâchoires étant disposées de façon mobile en rotation autour d'axes de rotation des mâchoires 10, 11 par rapport à une plaque de base ou embase 3.To hang the ski boot (not shown), two jaws 8, 9 are provided, these jaws being arranged so as to be able to rotate about axes of rotation of the jaws 10, 11 relative to a base plate or base 3.

Ces mâchoires 8, 9 pouvant pivoter ont un bras d'accrochage 12, 13 s'étendant chacun depuis les axes de rotation des mâchoires 10, 11 jusqu'à un point d'accrochage biellettes - mâchoires 14, 15. Une biellette 16 est articulée à ces points d'accrochage biellettes - mâchoires 14, 15, lesdites biellettes étant reliées l'une à l'autre par des boulons (non représentés) engagés dans les points d'accrochage biellettes - mâchoires 14, 15.These jaws 8, 9 which can pivot have a hooking arm 12, 13 each extending from the axes of rotation of the jaws 10, 11 to a point for hooking the rods - jaws 14, 15. A rod 16 is articulated at these connecting points for connecting rods - jaws 14, 15, said connecting rods being connected to each other by bolts (not shown) engaged in the connecting points for connecting rods - jaws 14, 15.

La liaison articulée des mâchoires 8, 9 via les axes de rotation 10, 11 des mâchoires avec la plaque de base 3 reposant dessous et via les points d'accrochage biellettes - mâchoires 14, 15 avec la biellette 16 permet à la biellette de coulisser sur une ligne reliant les points d'accrochage biellettes - mâchoires 14, 15.The articulated connection of the jaws 8, 9 via the axes of rotation 10, 11 of the jaws with the base plate 3 resting below and via the link points for connecting the jaws - jaws 14, 15 with the link 16 allows the link to slide on a line connecting the connecting points for connecting rods - jaws 14, 15.

Un bras de maintien 17, 18 au niveau de l'extrémité duquel un picot de maintien 19, 20 est respectivement prévu s'étend sur le côté des mâchoires 8, 9 opposé aux points d'accrochage biellettes - mâchoires et à la biellette, ledit picot s'étendant parallèlement à la biellette 16.A holding arm 17, 18 at the end of which a holding pin 19, 20 is respectively provided extends on the side of the jaws 8, 9 opposite the connecting points for connecting rods - jaws and to the connecting rod, said pin extending parallel to the connecting rod 16.

Il en résulte un parallélogramme dans lequel les deux côtés sont formés par les mâchoires, la ligne supérieure étant formée par la biellette et la ligne inférieure étant formée par le bout de la chaussure serré entre les picots de maintien 19, 20. Pour guider la chaussure de ski lors d'un mouvement des mâchoires 8, 9, les mâchoires 8, 9 comportent des rampes de mâchoire 22, 23 permettant, lors du de mouvement des mâchoires 8, 9, d'exercer une pression des mâchoires 8, 9 sur le bout de la chaussure de ski. Cette rampe des mâchoires 22, 23 agit de préférence conjointement avec des surfaces de déclenchement (ou rampes) 24, 25 d'un poussoir contre ledit poussoir 35.This results in a parallelogram in which the two sides are formed by the jaws, the upper line being formed by the link and the lower line being formed by the end of the shoe clamped between the holding pins 19, 20. To guide the shoe ski during movement of the jaws 8, 9, the jaws 8, 9 have jaw ramps 22, 23 allowing, during the movement of the jaws 8, 9, to exert pressure of the jaws 8, 9 on the tip of the ski boot. This ramp of the jaws 22, 23 preferably acts jointly with the triggering surfaces (or ramps) 24, 25 of a pusher against said pusher 35.

La biellette 16 comporte deux bras de biellette 28, 29, que nous appellerons alternativement plus simplement « biellettes », reliés entre eux via une liaison biellette 27. Ces bras de biellette 28, 29 sont disposés entre les points d'accrochage biellettes - mâchoires 14, 15 de telle sorte qu'ils puissent transmettre une force de poussée avec une composante s'étendant transversalement à la ligne reliant les points d'accrochage 14, 15. Bien que la biellette 16 se compose de deux bras de biellette 28, 29 reliés à une liaison biellette 27, la biellette 16 agit ainsi comme une barre d'une seule pièce transmettant la force de poussée. Ceci est pour l'essentiel réalisé par le fait que les bras de biellette 28, 29 comportent, outre la liaison biellette 27, une surface d'appui 30, 31 au niveau de laquelle les bras de biellette 28, 29 reposent les uns contre les autres.The link 16 comprises two link arms 28, 29, which we will alternatively more simply call "links", connected together via a link link 27. These link arms 28, 29 are arranged between the attachment points for links - jaws 14 , 15 so that they can transmit a pushing force with a component extending transversely to the line connecting the hooking points 14, 15. Although the link 16 consists of two link arms 28, 29 connected to a link rod 27, the rod 16 thus acts as a one-piece bar transmitting the pushing force. This is essentially achieved by the fact that the link arms 28, 29 comprise, in addition to the link link 27, a bearing surface 30, 31 at the level of which the link arms 28, 29 rest against each other. other.

Une came d'axe 32, un trou oblong 40 et une came d'accrochage 34 sont prévus dans la liaison biellette 27, ces éléments coopérant avec une clavette d'écartement 6. Cette clavette d'écartement 6 a une surface d'appui 7 en forme de V par le biais de laquelle les cames 32 et 34 sont écartées l'une de l'autre sur la longueur du trou oblong 40.An axis cam 32, an oblong hole 40 and a hooking cam 34 are provided in the link link 27, these elements cooperating with a spacer key 6. This spacer key 6 has a surface V-shaped support 7 by means of which the cams 32 and 34 are spaced from one another over the length of the oblong hole 40.

Un bras de biellette 28 ou 29 peut comporter une butée de positionnement 39 qui, lorsque la liaison biellette est pliée, sert de butée de positionnement pour une chaussure de ski lors de l'entrée dans la fixation.A link arm 28 or 29 may include a positioning stop 39 which, when the link link is folded, serves as a positioning stop for a ski boot when entering the binding.

Le poussoir 35 est coulissé contre la force d'un ressort de rappel 36. Ce ressort de rappel (ou ressort de déclenchement) 36 appuie d'une part contre le poussoir 35 et d'autre part contre un appui 37 fixé à la plaque de base 3. Une vis de réglage 38 permet en l'occurrence de faire varier la tension du ressort de rappel 36.The plunger 35 is slid against the force of a return spring 36. This return spring (or trigger spring) 36 bears on the one hand against the pusher 35 and on the other hand against a support 37 fixed to the plate. base 3. An adjustment screw 38 makes it possible in this case to vary the tension of the return spring 36.

La vue en coupe à travers la mâchoire avant indique la position de base en vue de dessus, correspondant à la position de montée et de descente. Les mâchoires 8, 9 reposent essentiellement de façon alignée parallèlement l'une par rapport à l'autre et dans la direction longitudinale de la plaque de base 3 et/ou d'un ski placé dessous. La biellette 16 reliant les mâchoires 8, 9 fait en sorte qu'en cas d'écartement latéral d'un picot de maintien 20, le picot de maintien 19 opposé soit ensuite guidé conjointement de telle sorte que la chaussure de ski (non représentée) reste maintenue fermement par les mâchoires 8, 9. Le ressort de rappel 36 agit sur les picots de maintien 19 et 20 via le poussoir 35 et les rampes de mâchoires 22 et 23.The sectional view through the front jaw indicates the basic position in top view, corresponding to the position of ascent and descent. The jaws 8, 9 rest essentially aligned in parallel with one another and in the longitudinal direction of the base plate 3 and / or of a ski placed below. The link 16 connecting the jaws 8, 9 ensures that in the event of lateral separation of a holding pin 20, the opposite holding pin 19 is then guided together so that the ski boot (not shown) remains firmly held by the jaws 8, 9. The return spring 36 acts on the holding pins 19 and 20 via the pusher 35 and the jaw ramps 22 and 23.

Un élément ressort 39 tire le piston 33 au niveau duquel la clavette d'écartement 6 est disposée avec ses surfaces d'appui 7 au-dessus du point de rotation 43, entre les cames 32 et 34, dans la direction F, et maintient ainsi les bras de biellette 28, 29 tendus au niveau de la butée 30/31.A spring element 39 pulls the piston 33 at the level of which the spacer key 6 is arranged with its bearing surfaces 7 above the point of rotation 43, between the cams 32 and 34, in the direction F, and thus maintains the link arms 28, 29 stretched at the stop 30/31.

Un dispositif 41 sur le côté supérieur de la fixation de ski, lorsqu'il est fortement sollicité par le bout de la chaussure de ski, peut mettre en appui un levier ou un poussoir 42 contre la biellette 16. Cela plie la biellette en forme de V et réduit ainsi l'écartement entre les points d'accrochage 14, 15 pour ainsi pouvoir écarter les extrémités des mâchoires 17, 18 au niveau desquelles les picots de maintien 19, 20 peuvent être disposés et libérer la chaussure de ski.A device 41 on the upper side of the ski binding, when it is strongly stressed by the end of the ski boot, can bear a lever or a push button 42 against the link 16. This folds the link in the form of V and thus reduces the spacing between the attachment points 14, 15 so as to be able to spread the ends of the jaws 17, 18 at the level of which the holding pins 19, 20 can be disposed and release the ski boot.

Finalement, un avantage de la solution provient des points d'accrochage des mâchoires reliés entre eux via une biellette. Cela a pour conséquence que les mâchoires ne sont pas déplacées indépendamment l'une de l'autre, mais qu'un déplacement d'une mâchoire a obligatoirement pour conséquence un mouvement de l'autre mâchoire. Cela permet de fixer la fixation de ski de telle sorte qu'une chaussure accrochée dans la fixation de ski puisse avoir un certain jeu de mouvement sans se détacher de la fixation. Ce n'est que lorsqu'un jeu prédéfini est dépassé que les mâchoires libèrent la chaussure de ski.Finally, an advantage of the solution comes from the attachment points of the jaws connected to each other via a link. This has the consequence that the jaws are not moved independently of each other, but that a displacement of one jaw necessarily results in a movement of the other jaw. This makes it possible to fix the ski binding so that a shoe hooked in the ski binding can have a certain play of movement without detaching from the binding. It is only when a predefined clearance is exceeded that the jaws release the ski boot.

Il est avantageux, pour que cela soit possible, que la biellette puisse coulisser sur une ligne reliant les points d'accrochage biellettes - mâchoires. La biellette peut ainsi coulisser par exemple par rapport à une plaque de base ou par rapport au ski sur lequel la fixation de ski est disposée. Avec des axes de rotation des mâchoires fixes, un tel coulissement sur une ligne entre les points d'accrochage biellettes - mâchoires provoque un coulissement de la position de mâchoire et ainsi un mouvement de la chaussure de ski accrochée dans la fixation de ski.It is advantageous, for this to be possible, for the link to slide on a line connecting the attachment points for links - jaws. The link can thus slide, for example relative to a base plate or relative to the ski on which the ski binding is arranged. With axes of rotation of the fixed jaws, such sliding on a line between the connecting points for connecting rods - jaws causes a sliding of the jaw position and thus a movement of the ski boot hooked in the ski binding.

Pour maintenir une chaussure de ski fermement, mais de façon mobile en rotation au niveau de la fixation de ski et notamment au niveau des mâchoires, il est proposé dans ce deuxième mode de réalisation que les mâchoires comportent un bras d'accrochage s'étendant de l'axe de rotation des mâchoires au point d'accrochage biellettes - mâchoires et un bras de maintien s'étendant de l'axe de rotation des mâchoires à un picot de maintien. Cela permet d'accrocher une chaussure de ski entre deux picots de maintien de deux mâchoires en introduisant les picots de maintien dans les évidements correspondants au niveau du bout de la chaussure de ski.To maintain a ski boot firmly, but movably in rotation at the ski binding and in particular at the jaws, it is proposed in this second embodiment that the jaws comprise a hooking arm extending from the axis of rotation of the jaws at the connecting point for connecting rods - jaws and a holding arm extending from the axis of rotation of the jaws to a holding pin. This allows a ski boot to be hung between two holding pins of two jaws by introducing the holding pins into the corresponding recesses at the end of the ski boot.

Pour simplifier une ouverture de la fixation de ski, il est proposé dans ce deuxième mode de réalisation que la biellette comporte deux bras de biellette reliés entre eux via une liaison biellette. Cela permet de plier la biellette et ainsi de réduire l'écartement entre les points d'accrochage pour séparer les extrémités des mâchoires au niveau desquelles des picots de maintien peuvent être disposés.To simplify an opening of the ski binding, it is proposed in this second embodiment that the link comprises two link arms connected to each other via a link link. This makes it possible to fold the link and thus reduce the spacing between the attachment points to separate the ends of the jaws at the level of which holding pins can be arranged.

Une liaison biellette rend plus difficile la transmission d'une force de poussée en direction de la biellette. Il est ainsi proposé que les bras de biellette soient disposés entre les points d'accrochage biellettes - mâchoires de telle sorte qu'ils puissent transmettre une force de poussée avec une composante s'étendant transversalement à la ligne des points d'accrochage.A link link makes it more difficult to transmit a pushing force towards the link. It is thus proposed that the link arms are arranged between the link points for connecting the jaws so that they can transmit a thrust force with a component extending transversely to the line of the attachment points.

Une façon simple de le réaliser est que les bras de biellette comportent, outre la liaison biellette, une surface d'appui. La liaison biellette pourrait toutefois également comporter par exemple des positions prédéfinies pour l'encliquetage accrochant les bras de biellette dans une orientation spécifique les uns par rapport aux autres.A simple way to achieve this is that the link arms have, in addition to the link link, a bearing surface. The link rod could however also include, for example, predefined positions for the snap hooking the link arms in a specific orientation relative to each other.

Pour déplacer de façon commandée les bras de biellette, il est proposé que la liaison biellette comporte une came guidée dans un trou oblong et que la came soit disposée fixement. Une deuxième came sert de contre-palier au niveau de l'autre bras de biellette. En l'occurrence, les cames peuvent faire partie de la biellette.To move the link arms in a controlled manner, it is proposed that the link link comprises a cam guided in an oblong hole and that the cam is fixedly disposed. A second cam serves as a counter bearing at the other link arm. In this case, the cams can be part of the link.

Pour garantir notamment une adaptation automatique en largeur des mâchoires l'une par rapport à l'autre et à une chaussure de ski, il est proposé que les bras de biellette soient repoussés à l'écart l'un de l'autre contre la came dans la mesure limite de la longueur du trou oblong en s'aidant d'une clavette d'écartement.To guarantee in particular an automatic adaptation in width of the jaws relative to each other and to a ski boot, it is proposed that the link arms are pushed away from one another against the cam in the limit measurement of the length of the oblong hole with the help of a spacer key.

Une variante de réalisation avantageuse prévoit que la clavette d'écartement soit disposée autour d'un axe pouvant pivoter verticalement, au niveau d'un piston ne pouvant coulisser que dans un plan transversalement à une ligne reliant les axes de rotation des mâchoires. Ce piston de préférence mobile dans la direction longitudinale du ski et sous tension de ressort tire la clavette d'écartement entre les cames sur la largeur d'écartement maximale permise dans chaque cas par la longueur du trou oblong.An advantageous alternative embodiment provides that the spacer key is arranged around an axis which can pivot vertically, at the level of a piston which can only slide in a plane transversely to a line connecting the axes of rotation of the jaws. This piston, preferably movable in the longitudinal direction of the ski and under spring tension, pulls the spacer key between the cams over the maximum spacing width permitted in each case by the length of the oblong hole.

En l'occurrence, il est avantageux que le piston puisse coulisser à l'encontre de la force d'un ressort accroché d'une part au piston pouvant coulisser et d'autre part à un appui fixe. L'appui fixe peut avoir pour effet que la clavette d'écartement ait toujours le plus grand effet d'écartement par rapport aux cames, et donc par rapport aux bras de biellette.In this case, it is advantageous that the piston can slide against the force of a spring attached on the one hand to the piston which can slide and on the other hand to a fixed support. The fixed support can have the effect that the spacer key always has the greatest spacing effect with respect to the cams, and therefore with respect to the link arms.

Étant donné qu'en fonction de la réalisation des picots de maintien et des évidements de la chaussure de ski, l'écartement entre les picots de maintien dans leur position d'accrochage varie, le dispositif décrit ci-dessus est proposé pour compenser ce jeu. La biellette comporte à cette fin deux bras de biellette reliés entre eux de façon à pouvoir pivoter via une came d'accrochage guidée dans un trou oblong. Une came d'accrochage est disposée au niveau d'un bras de biellette et une came d'axe et un trou oblong, dans lequel est guidée la came d'accrochage opposée, sont disposés au niveau de l'autre bras de biellette. Un mouvement de la came d'accrochage et de la came d'axe vers le bout du ski déplace les picots de maintien l'un vers l'autre tandis que la clavette d'écartement glisse le long de la came d'accrochage et de commande. La clavette d'écartement ne repousse en l'occurrence les bras de biellette à l'écart l'un de l'autre que jusqu'à ce que les picots de maintien adoptent l'écartement nécessaire pour un accrochage sûr de la chaussure de ski et que les bras de biellette soient approximativement alignés sur une ligne.Since, depending on the shape of the holding pins and the recesses of the ski boot, the spacing between the holding pins in their hooking position varies, the device described above is proposed to compensate for this play The link comprises for this purpose two link arms connected together so as to be able to pivot via a hooking cam guided in an oblong hole. A hooking cam is arranged at a link arm and a cam axis and an oblong hole, in which the opposite hooking cam is guided, are arranged at the level of the other link arm. A movement of the hooking cam and the shaft cam towards the end of the ski moves the holding pins towards one another while the spacer key slides along the hooking cam and ordered. In this case, the spacer key only pushes the link arms away from each other until the holding pins adopt the spacing necessary for secure attachment of the ski boot. and that the link arms are approximately aligned on a line.

Pour accrocher de façon sûre la chaussure de ski, il est proposé dans ce deuxième mode de réalisation que les mâchoires comportent une surface d'appui coopérant avec les contre-surfaces au niveau d'un poussoir chargé par ressort comportant respectivement à son tour un bord de déclenchement. Tant que les mâchoires sont chargées de façon uniforme via ces surfaces d'appui, les picots de maintien tentent d'adopter l'écartement le plus réduit possible les uns par rapport aux autres dans les mâchoires.To securely hang the ski boot, it is proposed in this second embodiment that the jaws have a bearing surface cooperating with the counter-surfaces at the level of a spring-loaded pusher respectively comprising in turn an edge trigger. As long as the jaws are loaded uniformly via these bearing surfaces, the holding pins try to adopt the smallest possible spacing with respect to each other in the jaws.

Il est en l'occurrence avantageux que les mâchoires commandées par le poussoir chargé par ressort adoptent d'abord, via les picots de maintien, leur position d'extrémité dans les évidements de chaussure de ski. La clavette d'écartement, avec un léger retard, doit ensuite repousser à l'écart l'un de l'autre les bras de biellette et agir comme une entretoise sur les bras de biellette.It is in this case advantageous that the jaws controlled by the spring loaded pusher first adopt, via the holding pins, their end position in the ski boot recesses. The spacer key, with a slight delay, must then push the link arms away from each other and act as a spacer on the link arms.

Lorsqu'un skieur tombe en avant, donc dans la direction de conduite, la fixation de ski doit aussitôt se débloquer dans la direction avant. Pour permettre une ouverture de la fixation de ski dans cette direction, il est proposé dans ce deuxième mode de réalisation que la biellette comporte deux bras de biellette reliés entre eux via une liaison biellette et un dispositif sur un côté supérieur de la fixation de ski qui, lorsqu'il est fortement sollicité par le bout de la chaussure, presse directement ou via un levier supplémentaire contre la biellette de telle sorte que la biellette plie dans une position avant le point-mort et réduise ainsi l'écartement entre les points d'accrochage, permettant d'écarter l'une de l'autre les extrémités des mâchoires au niveau desquelles les picots de maintien peuvent être disposés, pour libérer la chaussure de ski.When a skier falls forward, therefore in the driving direction, the ski binding must immediately be released in the forward direction. To allow the ski binding to open in this direction, it is proposed in this second embodiment that the link comprises two link arms linked together via a link link and a device on an upper side of the ski binding which, when it is strongly stressed by the end of the boot, presses directly or via an additional lever against the link of such so that the rod folds into a position before neutral and thus reduces the spacing between the attachment points, making it possible to separate the ends of the jaws from one another at the level of which the holding pins can be arranged to release the ski boot.
