Abstract

The safety binding consists of a jaw (3) pivoted to a body (2) about a transverse axis so that it can rotate between open and closed positions. The jaw is held in the closed position by an elastic system with a piston (6) which interacts with a sloping surface in the jaw. The piston being urged upwards by at least one retaining link (14b), and preferably by one on each side of the piston. An axial line through the centres of the links' pivots is situated generally vertically. It is angled slightly towards the boot in the closed position of the jaw and slightly away from the vertical in the open position. A lever (11) which releases the binding is articulated to the piston about the transverse axis of the upper link pivot (12).

Description

L'invention concerne un dispositif de retenue d'une chaussure à une planche de glisse telle qu'un ski ou similaire, comme, par exemple, un monoski, surf de neige et autre. Un tel dispositif étant généralement appelé dans le domaine du ski "fixation de ski".The invention relates to a device for retaining a shoe with a gliding board such as a ski or the like, for example a monoski, snowboard and more. Such a device is generally called in the field of skiing "ski binding".

L'invention concerne plus particulièrement un dispositif destiné à retenir de façon déclenchable l'arrière de la chaussure de l'utilisateur qui est plus communément appelée "talonnière".The invention relates more particularly to a device intended for releasably hold the back of the user's shoe which is more commonly called "heel piece".

On connaít déjà de très nombreuses fixations de sécurité destinées à maintenir une chaussure sur un ski pour permettre, d'une part, la pratique du ski et, d'autre part, la libération de ladite chaussure quand il apparaít une sollicitation dangereuse pour la jambe du skieur. De telles fixations comprennent une mâchoire pivotante sollicitée par un système élastique, tandis qu'un levier de déchaussage permet à l'utilisateur d'ouvrir la mâchoire pour permettre la libération volontaire de sa chaussure.We already know many security fasteners intended to hold a shoe on a ski to allow, on the one hand, skiing and, on the other hand, releasing said shoe when it appears a dangerous request for the leg of the skier. Such fasteners include a pivoting jaw stressed by a system elastic, while a release lever allows the user to open the jaw to allow the voluntary release of his shoe.

On peut noter, par exemple, les fixations talonnière décrites dans les brevets français n° 2 492 668, n° 2 338 060 ou encore n° 2 494 591 et n° 2 717 400. Dans toutes ces réalisations, on trouve un système élastique constitué par un organe mobile en coulissement, sollicité par un ressort en appui sur une rampe de déclenchement réalisée à l'intérieur d'une mâchoire de retenue, ladite rampe étant prolongée vers le bas par une deuxième rampe, dite rampe d'ouverture, permettant le maintien en position ouverte de ladite mâchoire. Ces fixations, bien que déjà perfectionnées, présentent un certain nombre d'inconvénients, et notamment celui de n'être pas fiables et donner, pour une compression de ressort déterminée, des efforts de déclenchement variables, ce qui, dans certains cas, peut être dangereux pour le skieur qui fait totalement confiance à son matériel. Ces variations d'effets de déclenchement sont dues en grande partie à des effets indésirés parasites tels que la flexion de l'organe mobile et les frottements de ce dernier dans son logement de coulissement lors de son déplacement.We can note, for example, the heel fixings described in French Patents No. 2,492,668, No. 2,338,060 or No. 2,494,591 and No. 2,717,400. In all these embodiments, there is an elastic system constituted by a mobile sliding member, biased by a spring resting on a trip ramp made inside a retaining jaw, said ramp being extended downwards by a second ramp, called the opening ramp, allowing the maintenance in open position of said jaw. These fixings, although already improved, have a number of drawbacks, and especially that of being unreliable and giving, for compression determined spring, variable tripping forces, which, in some cases can be dangerous for the skier who does trust his material. These variations in trigger effects are largely due to unwanted unwanted effects such as bending of the movable member and the friction of the latter in its housing sliding during its displacement.

On connait aussi les dispositifs divulgués par les documents DE-A-2 200 768 et DE-A-3 322 634 qui comprennent un organe mobile retenu par une biellette, le levier de dechaussage etant par articulé sur un axe propre. We also know the devices disclosed by the documents DE-A-2 200 768 and DE-A-3 322 634 which include a movable member retained by a link, the release lever being by articulated on its own axis.

La présente invention veut remédier aux inconvénients rencontrés avec les fixations traditionnelles actuellement connues en proposant un nouveau dispositif de retenue particulièrement simple et fiable.The present invention seeks to remedy the drawbacks encountered with traditional fasteners currently known in offering a new particularly simple and reliable.

Ce but est atteint en prévoyant des moyens permettant la retenue vers le bas de l'extrémité de l'organe mobile de verrouillage, ces moyens étant constitués par au moins une biellette articulée, d'une part, sur l'organe mobile coulissant et, d'autre part, sur le corps de la fixation.This goal is achieved by providing means for restraint downwards from the end of the movable locking member, these means being constituted by at least one articulated link, on the one hand, on the movable sliding member and, on the other hand, on the body of the binding.

Selon une autre caractéristique de l'invention, le levier de déchaussage est articulé sur le piston sur le même axe d'articulation de la ou des biellette(s) de retenue.According to another characteristic of the invention, the lever heaving is articulated on the piston on the same articulation axis of the or retaining rod (s).

Dans une disposition avantageuse, le piston coulissant comprend deux biellettes latérales s'étendant vers le bas, tandis que dans l'un des modes d'exécution, les deux biellettes sont reliées à leur extrémité supérieure par une traverse transversale pour former un étrier en forme de U ouvert vers le bas.In an advantageous arrangement, the sliding piston comprises two side links extending downwards, while in one of the embodiments, the two rods are connected at their ends upper by a transverse cross to form a shaped stirrup from U open down.

Ainsi, selon l'invention, la fixation de sécurité est destinée à retenir de façon déclenchable une chaussure à un ski ou similaire, et est du type comprenant une mâchoire montée pivotante sur un corps autour d'un axe transversal, de manière à être mobile en rotation entre une position de fermeture et une position d'ouverture et inversement, ladite mâchoire étant retenue en position de fermeture par un système élastique, et comprenant de plus un levier de déchaussage mobile en pivotement autour d'un axe transversal, de manière à être mobile entre une position selon laquelle il s'étend vers le haut et une position d'ouverture selon laquelle il s'étend vers l'arrière, ledit système élastique comprenant un piston mobile en déplacement longitudinal sollicité par un ressort en appui sur une rampe réalisée dans la mâchoire, ledit piston etant retenu vers le haut par au moins une biellette de retenue articulée sur le corps par son extrémité inférieure autour d'un axe transversal, et est caracterise en ce que le levier de dechaussage est articule sur le piston autour de l'axe transversal, au quel sont déjà articulées la ou les biellettes de retenue. Thus, according to the invention, the security attachment is intended for releasably hold a boot to a ski or the like, and is of the type comprising a jaw pivotally mounted on a body around of a transverse axis, so as to be movable in rotation between a closed position and an open position and vice versa, said jaw being retained in the closed position by a system elastic, and further comprising a movable release lever in pivoting about a transverse axis, so as to be movable between a position in which it extends upwards and a position opening at which it extends rearward, said elastic system comprising a piston movable in longitudinal displacement urged by a spring resting on a ramp made in the jaw, said piston being retained upwards by at least one retaining link articulated on the body by its lower end around a transverse axis, and is characterized in that the lever of shoe is hinged on the piston around the axis transverse, to which the retaining link (s) are already articulated.

Selon une caractéristique complémentaire, la biellette de retenue est articulée par son extrémité supérieure autour d'un axe transversal sur la partie avant du piston.According to an additional characteristic, the retaining link is articulated by its upper end around a transverse axis on the front part of the piston.

Selon une disposition préférée, le piston comprend deux biellettes latérales de retenue disposées latéralement de part et d'autre de celui-ci, tandis que l'axe général de chacune des biellettes joignant les centres des deux axes s'étend sensiblement verticalement, pour être avantageusement dans la position de fermeture légèrement incliné vers l'avant et vers le haut pour former un angle aigu avec la verticale, tandis qu'en position d'ouverture, l'axe est légèrement incliné vers l'arrière et vers le haut, pour former un angle aigu avec ladite verticale.According to a preferred arrangement, the piston comprises two lateral retaining rods arranged laterally on either side of this one, while the general axis of each of the connecting rods centers of the two axes extends substantially vertically, to be advantageously in the closed position slightly inclined towards forward and upward to form an acute angle with the vertical while in the open position, the axis is tilted slightly backwards and upward, to form an acute angle with said vertical.

Selon une autre disposition avantageuse, les deux biellettes latérales sont disposées dans des dégagements latéraux réalisés dans les parois latérales du pistonAccording to another advantageous arrangement, the two links lateral are arranged in lateral clearances made in the side walls of the piston

Dans une variante d'exécution, les deux biellettes latérales de retenue sont reliées par leur extrémité supérieure par une traverse transversale pour former un étrier de retenue ayant la forme d'un "U" ouvert vers le bas.In an alternative embodiment, the two lateral links of retainers are connected by their upper end by a cross transverse to form a retaining clip in the shape of a "U" open down.

Ajoutons que le piston comprend une partie arrière comprenant un trou central destiné à recevoir le ressort, prolongée vers l'avant par une partie avant comprenant un nez d'appui transversal destiné à coopérer avec la rampe de la mâchoire, tandis que ladite partie arrière est sensiblement parallélépipèdique et sa paroi inférieure comprend à son extrémité une saillie transversale d'appui destinée à être en appui coulissant sur la face inférieure d'appui du logement dans lequel se déplace le piston.Add that the piston includes a rear part comprising a central hole intended to receive the spring, extended forwards by a front part comprising a transverse bearing nose intended for cooperate with the ramp of the jaw, while said rear part is substantially parallelepipedic and its lower wall comprises at its end a transverse support projection intended to be in support sliding on the underside of the housing support in which moves the piston.

On comprendra que grâce aux biellettes de retenue le piston aura un déplacement vers l'arrière sans reproche et constant, tandis que les efforts s'exerçant sur le levier lors d'un déchaussage volontaire seront parfaitement encaissés, sans risque de détérioration du piston.It will be understood that thanks to the retaining rods the piston will have constant and flawless backward movement, while forces exerted on the lever during voluntary heaving will be perfectly cashed, without risk of damage to the piston.

    • On décrira tout d'abord une première réalisation d'une fixation portant la référence générale (1) destinée à retenir de façon déclenchable une chaussure (40) à un ski (50) et qui est destinée à retenir plus particulièrement l'arrière de la chaussure par son talon. Ce type de fixation étant plus communément appelée talonnière (1) et comprend un plan vertical (P) de symétrie général.We will first describe a first realization of a fixation bearing the general reference (1) intended to retain so triggerable a shoe (40) to a ski (50) and which is intended to retain more particularly the back of the shoe by its heel. This kind of binding being more commonly called heel piece (1) and includes a vertical plane (P) of general symmetry.

    Ladite talonnière (1) comprend un corps (2) sur lequel est articulée une mâchoire de retenue (3). A cet effet, cette dernière est montée pivotante sur le corps autour d'un axe transversal (4) pour être mobile en pivotement entre une position de retenue de la chaussure tel qu'illustré à la figure 2 et une position de libération tel que représenté par la figure 1 et inversement.Said heel piece (1) comprises a body (2) on which is articulated a retaining jaw (3). For this purpose, the latter is pivotally mounted on the body about a transverse axis (4) to be pivotally movable between a shoe retaining position such as illustrated in Figure 2 and a release position as shown by Figure 1 and vice versa.

    La mâchoire (1) est sollicitée en position de retenue de la chaussure par l'action d'un système élastique (5) constitué par un organe mobile de verrouillage (6) sollicité par un ressort (7) sur une rampe de déclenchement (8) réalisée à l'intérieur de la mâchoire (3), ladite rampe de déclenchement (8) étant, par ailleurs, avantageusement prolongée vers le bas par une deuxième rampe ou rampe d'ouverture (9) permettant à la mâchoire de pouvoir se placer en position de libération et d'ouverture tel que cela est illustré à la figure 1.The jaw (1) is biased in the retaining position of the shoe by the action of an elastic system (5) constituted by a member locking mobile (6) biased by a spring (7) on a ramp trigger (8) produced inside the jaw (3), said ramp trigger (8) being, moreover, advantageously extended towards the bottom by a second ramp or opening ramp (9) allowing the jaw can be placed in the release and opening position as as illustrated in Figure 1.

    Selon une des caractéristiques de l'invention, l'organe mobile de verrouillage (6) est constitué par un piston coulissant mobile en translation selon l'axe longitudinal (XX') du ski, dans un logement central de coulissement (10) réalisé dans le corps (2) de la fixation (1).According to one of the characteristics of the invention, the movable member of locking (6) is constituted by a sliding piston movable in translation along the longitudinal axis (XX ') of the ski, in a central housing sliding (10) made in the body (2) of the fastener (1).

    Le piston (6) plus particulièrement visible aux figures 7, 9 et 10 comprend une partie arrière (60) sensiblement parallélépipèdique, comprenant un trou central longitudinal (61) destiné à recevoir le ressort (7), prolongée par une partie avant (62) comprenant un nez d'appui transversal (63) destiné à coopérer avec les rampes (8, 9) de la mâchoire. Par ailleurs, ladite partie avant (62) comprend une saillie supérieure transversale (64) traversée transversalement par un trou transversal (65) recevant un axe transversal (12) de pivotement dont on expliquera la fonction, ainsi que deux dégagements latéraux (68a, 68b). Notons aussi que la paroi inférieure (66) de la partie arrière (60) comprend à son extrémité une saillie transversale d'appui (67).The piston (6) more particularly visible in Figures 7, 9 and 10 comprises a rear part (60) substantially parallelepiped, comprising a longitudinal central hole (61) intended to receive the spring (7), extended by a front part (62) comprising a support nose transverse (63) intended to cooperate with the ramps (8, 9) of the jaw. Furthermore, said front part (62) comprises an upper projection transverse (64) traversed transversely by a transverse hole (65) receiving a transverse pivot axis (12) which will be explained function, as well as two lateral clearances (68a, 68b). Also note that the lower wall (66) of the rear part (60) comprises at its end a transverse support projection (67).

    Par ailleurs, il est prévu un levier pivotant de déchaussage (11) qui permet à l'utilisateur de pouvoir libérer sa chaussure par pivotement de la mâchoire de sa position de retenue vers sa position de libération. Ainsi, dans la position de retenue de la mâchoire, ledit levier s'étend vers le haut (HA) pour pouvoir être pivoté vers l'arrière et vers le bas selon F1 pour forcer la mâchoire à l'ouverture. A cet effet, le levier de déchaussage est monté pivotant sur le piston (6) grâce à l'axe de pivotement transversal (12) avantageusement, désigné précédemment. Ledit levier (11) est réalisé, par exemple, avec de la tôle d'acier, et comprend au moins une paroi transversale (13) prolongée latéralement par deux parois latérales (13a, 13b) verticales s'étendant vers le bas, dont les extrémités avant sont disposées entre les flancs latéraux (30a, 30b) de la mâchoire (3) et les parois latérales (20a, 20b) correspondantes du corps (2) de la talonnière. Par ailleurs, chacune des extrémités avant des parois latérales du levier comprend, d'une part, à sa partie inférieure une saillie de déchaussage (110), et, d'autre part, à sa partie supérieure une saillie de chaussage volontaire (111).Furthermore, a pivoting heaving lever (11) is provided which allows the user to be able to release his shoe by pivoting the jaw from its rest position to its release position. So, in the jaw retaining position, said lever extends towards the up (HA) so that it can be pivoted backwards and downwards according to F1 to force the jaw to open. To this end, the heaving lever is pivotally mounted on the piston (6) thanks to the pivot axis advantageously transverse (12), designated previously. Said lever (11) is made, for example, from sheet steel, and comprises at at least one transverse wall (13) extended laterally by two vertical side walls (13a, 13b) extending downwards, the front ends are arranged between the lateral flanks (30a, 30b) of the jaw (3) and the corresponding side walls (20a, 20b) of the body (2) from the heel piece. In addition, each of the front ends of the walls side of the lever comprises, on the one hand, at its lower part a projection heaving (110), and, on the other hand, at its upper part a projection of voluntary footwear (111).

    Selon l'invention, l'extrémité avant du piston coulissant (6) est retenue au corps (2) par au moins une biellette de retenue (14a, 14b), ladite biellette étant articulée sur le piston (6) par une de ses extrémités, autour d'un premier axe transversal (MM'), tandis que l'autre de ses extrémités est articulée sur le corps (2) autour d'un deuxième axe transversal (NN').According to the invention, the front end of the sliding piston (6) is retained on the body (2) by at least one retaining link (14a, 14b), said link being articulated on the piston (6) by one of its ends, around a first transverse axis (MM '), while the other of its ends is articulated on the body (2) around a second axis transverse (NN ').

    Selon une caractéristique complémentaire, la biellette de retenue est articulée sur le piston autour d'un axe (12) matérialisant le premier axe transversal (MM') servant aussi d'articulation pour le levier de déchaussage. Selon le premier mode de réalisation illustré aux figures 1 à 14, le piston coulissant (6) comprend deux biellettes latérales de retenue (14a, 14b) disposées latéralement de part et d'autre dudit piston (6) entre ledit piston et les parois intérieures latérales du logement (10) réalisé dans le corps pour le déplacement du piston. Ainsi, le piston comprend une biellette gauche (14a) et une biellette droite (14b). Chacune des biellettes est articulée par son extrémité supérieure (141) sur le piston autour de l'axe (12) permettant aussi le pivotement du levier de déchaussage, tandis que son extrémité inférieure (142) est articulée sur la partie inférieure avant (21) du corps (2) autour d'un axe transversal (15) matérialisant le deuxième axe transversal (NN'). Ainsi chacune des biellettes qui est réalisée à partir d'une tôle d'acier comprend à son extrémité supérieure (141) un premier trou (120) destiné à recevoir l'axe transversal (12) et à son extrémité inférieure (142) un deuxième trou (150) destiné à recevoir l'axe transversal inférieur de pivotement (15). Ajoutons que chacune des biellettes de retenue est logée dans le dégagement latéral (68a, 68b) correspondant réalisé dans la partie avant du piston (6).According to an additional characteristic, the retaining link is articulated on the piston around an axis (12) materializing the first transverse axis (MM ') also serving as an articulation for the lever heaving. According to the first embodiment illustrated in Figures 1 to 14, the sliding piston (6) comprises two lateral retaining links (14a, 14b) arranged laterally on either side of said piston (6) between said piston and the inner side walls of the housing (10) produced in the body for the displacement of the piston. So the piston includes a left link (14a) and a right link (14b). Each of rods is articulated by its upper end (141) on the piston around the axis (12) also allowing the pivoting of the lever heaving, while its lower end (142) is articulated on the lower front part (21) of the body (2) around a transverse axis (15) materializing the second transverse axis (NN '). So each of rods which is made from a steel sheet includes at its upper end (141) a first hole (120) intended to receive the axis transverse (12) and at its lower end (142) a second hole (150) intended to receive the lower transverse pivot axis (15). Let's add that each of the retaining links is housed in the clearance lateral (68a, 68b) corresponding made in the front part of the piston (6).

    L'axe général (YY') de chacune des biellettes joignant les centres des deux axes (12, 15) s'étend sensiblement verticalement, pour être avantageusement dans la position chaussée de la fixation (figures 2, 5 et 13) légèrement incliné vers l'avant (AV) et vers le haut (HA) pour former un angle aigu (A) avec la verticale, tandis qu'en position ouverte (figures 1 et 13a), l'axe (YY') est légèrement incliné vers l'arrière (AR) et vers le haut (HA), pour former un angle aigu (B) avec ladite verticale. De façon avantageuse, l'angle (A) est sensiblement égal à l'angle (B), de façon à ce que, lors de la rotation de la mâchoire, l'axe de pivotement (12) ne se déplace que très légèrement en hauteur.The general axis (YY ') of each of the connecting rods joining the centers of the two axes (12, 15) extends substantially vertically, so as to be advantageously in the pavement position of the attachment (FIGS. 2, 5 and 13) slightly inclined towards the front (AV) and upwards (HA) to form an acute angle (A) with the vertical, while in the open position (Figures 1 and 13a), the axis (YY ') is slightly inclined towards the 'back (AR) and up (HA), to form an acute angle (B) with said vertical. Advantageously, the angle (A) is substantially equal to the angle (B) so that, upon rotation of the jaw, the pivot axis (12) moves only very slightly height.

    Lors d'un déclenchement en sécurité, la mâchoire (3) sollicitée par le talon de la chaussure pivote vers le haut selon (R1) autour de son axe (4). Lors de ce mouvement, la rampe de déclenchement (8) sollicite le piston selon un effort Q qui se décompose en deux efforts orthogonaux, un effort vertical dirigé vers le haut (S) et un effort horizontal dirigé vers l'arrière (R). L'action de la rampe sur le piston (6) provoque alors son déplacement en coulissement vers l'arrière contre l'action du ressort (7). Lors de son déplacement en coulissement longitudinal, le piston prend appui par sa saillie (67) sur la face inférieure (100) du logement de coulissement (10), ladite saillie (67) se déplaçant vers l'arrière sur cette face inférieure d'appui (100). Par ailleurs, les biellettes retiennent l'avant du piston, pour assurer sa retenue vers le haut et encaisser ainsi l'effort vertical (S) dirigé vers le haut appliqué sur ledit piston par la rampe (8) de la mâchoire (3).When triggered safely, the jaw (3) stressed by the heel of the shoe pivots upward along (R1) around its axis (4). During this movement, the trigger ramp (8) urges the piston according to an effort Q which is broken down into two efforts orthogonal, a vertical force directed upwards (S) and a force horizontal directed backwards (R). The action of the ramp on the piston (6) then causes it to slide backwards against the action of the spring (7). During its sliding movement longitudinal, the piston is supported by its projection (67) on the underside (100) of the sliding housing (10), said projection (67) moving backwards on this lower support face (100). In addition, rods retain the front of the piston, to ensure its upward retention and thus absorb the vertical force (S) directed upwards applied to said piston by the ramp (8) of the jaw (3).

    Selon une caractéristique complémentaire de l'invention, rappelons que le levier de déchaussage (11) est avantageusement articulé sur le piston (6) autour de l'axe (12) servant aussi d'axe de pivotement pour les biellettes de retenue.According to an additional characteristic of the invention, remember that the release lever (11) is advantageously articulated on the piston (6) around the axis (12) also serving as a pivot axis for retaining links.

    Les figures 15 à 20 illustrent une variante d'exécution selon laquelle les deux biellettes latérales de retenue (14a, 14b) sont reliées par leur extrémité supérieure par une traverse transversale (14c) pour former un étrier de retenue (140) ayant la forme d'un U ouvert vers le bas. Dans ce mode de réalisation, la traverse transversale supérieure (14c) est destinée à retenir vers le haut le piston (6), lorsque la chaussure est retenue sur le ski, et lors d'un déchaussage en sécurité par sollicitation vers le haut de la chaussure. A cet effet, la traverse (14c) comprend une saillie (14d) s'étendant transversalement vers le bas sur laquelle la face supérieure (69) de l'avant du piston (6) vient s'appuyer dans les positions évoquées précédemment, à savoir, lorsque la chaussure est retenue sur le ski et lors d'un déchaussage en sécurité. Par ailleurs, chacune des biellettes latérales (14a, 14b) comprend un trou (120') légèrement oblong permettant, d'une part, le passage de l'axe (12) du levier (11) et, d'autre part, le mouvement relatif vertical dudit axe, lors du fonctionnement de la fixation (tel que cela est illustré aux figures 19 et 20). La figure 19 illustre schématiquement et partiellement la fixation lors d'un déclenchement en sécurité. Lors de ce mouvement, la mâchoire (3) est sollicitée vers le haut par la chaussure et pivote selon (R1) autour de son axe (4). Lors de ce mouvement de pivotement, la rampe de déclenchement (8) sollicite le nez (63) du piston vers le haut, ce qui provoque un léger soulèvement de l'avant du piston qui se soulève jusqu'à être en appui sur la traverse (14c) par sa face supérieure (69). On se trouve d'ailleurs dans cette situation quand la fixation est dans sa position chaussée de retenue de la chaussure.Figures 15 to 20 illustrate an alternative embodiment according to which the two lateral retaining links (14a, 14b) are connected by their upper end by a transverse crosspiece (14c) to form a retaining clip (140) having the shape of a U open downwards. In this embodiment, the upper transverse cross member (14c) is intended to hold up the piston (6), when the shoe is retained on the ski, and during a safety heaving by solicitation to the top of the shoe. For this purpose, the crosspiece (14c) comprises a projection (14d) extending transversely downward on which the face upper (69) of the front of the piston (6) comes to rest in the positions previously mentioned, namely, when the shoe is retained on the ski and during a heaving in safety. In addition, each of the links side (14a, 14b) includes a slightly oblong hole (120 ') allowing, on the one hand, the passage of the axis (12) of the lever (11) and, on the other hand, the relative vertical movement of said axis, during the operation of the attachment (as illustrated in Figures 19 and 20). Figure 19 illustrates schematically and partially the attachment when triggered in security. During this movement, the jaw (3) is biased upwards by the shoe and pivots along (R1) around its axis (4). During this pivoting movement, the release ramp (8) requests the nose (63) of the piston upwards, causing a slight lifting of the front of the piston which lifts until it rests on the cross-member (14c) by its upper face (69). We are also in this situation when the binding is in its carriageway retaining position shoe.

    La figure 20 illustre schématiquement et partiellement la fixation dans la position correspondant à celle où la mâchoire (3) est ouverte, prête à être chaussée, correspondant aussi sensiblement à celle de la fixation lors d'un chaussage en automatique par appui de la chaussure sur la pédale (300). Lors de ce mouvement, la rampe inférieure (9) sollicite alors vers le bas le nez du piston, ce qui provoque un léger déplacement vers le bas de l'avant du piston, qui se déplace jusqu'à ce que l'axe (12) soit en appui sur le bord périphérique inférieur du trou (120').Figure 20 schematically and partially illustrates the attachment in the position corresponding to that where the jaw (3) is open, ready to be paved, also corresponding substantially to that of the fixation during an automatic boot by pressing the shoe on the pedal (300). During this movement, the lower ramp (9) urges then down the nose of the piston, which causes a slight displacement down from the front of the piston, which moves until the axle (12) either resting on the lower peripheral edge of the hole (120 ').

    La figure 21 est une illustration en perspective représentant une autre variante d'exécution selon laquelle le piston (6) ne comprend qu'une seule biellette de retenue (14).Figure 21 is a perspective illustration showing a another variant according to which the piston (6) does not include only one retaining link (14).

    On a vu précédemment que chacune des biellettes (14a, 14b, 14) ou similaire, comme l'étrier (140) est articulée et retenue pivotante sur le corps (2) autour d'un axe (15) qui est engagé dans un trou transversal correspondant (152) réalisé dans la partie inférieure avant du corps. Toutefois, tous autres types de disposition de retenue des biellettes pourrait être adaptés comme, par exemple, ceux illustrés aux figures 22, 23, 24 et 25. Ces figures illustrent deux variantes d'exécution selon lesquelles les deux biellettes latérales de retenue sont reliées par leur extrémité inférieure (142) par une traverse inférieure de retenue et de pivotement (14e) qui constitue un profil cylindrique destiné à être engagé dans un logement transversal (210) réalisé dans la partie inférieure avant (21) du corps formant une sorte de crochet de retenue et de pivotement, la coopération entre la traverse inférieure (14e) et le logement transversal (210) créant ainsi le deuxième axe transversal (NN').We have previously seen that each of the links (14a, 14b, 14) or similar, as the stirrup (140) is articulated and pivotally retained on the body (2) around an axis (15) which is engaged in a transverse hole corresponding (152) made in the lower front part of the body. However, all other types of tie rod retaining arrangement could be adapted as, for example, those illustrated in FIGS. 22, 23, 24 and 25. These figures illustrate two alternative embodiments according to which the two lateral retaining links are connected by their lower end (142) by a lower cross member for retaining and pivot (14e) which constitutes a cylindrical profile intended to be engaged in a transverse housing (210) made in the lower front part (21) of the body forming a sort of retaining and pivoting hook, the cooperation between the lower crosspiece (14e) and the transverse housing (210) thus creating the second transverse axis (NN ').

    Les figures 22 et 23 illustrent une première variante selon laquelle les deux biellettes latérales ne sont pas reliées par leurs extrémités supérieures, tandis que les figures 21 et 24 illustrent une deuxième variante selon laquelle la retenue du piston est réalisée par un étrier (140') du type de celui de la réalisation des figures 15 à 20.Figures 22 and 23 illustrate a first variant according to which the two side links are not connected by their ends figures 21 and 24 illustrate a second variant according to which the piston is retained by a caliper (140 ') of the type from that of the embodiment of FIGS. 15 to 20.

    La figure 26 est une illustration en perspective d'une autre possibilité de réalisation pour réaliser le pivotement des biellettes. Selon cette variante chacune des biellettes comprend une saillie inférieure (15') destinée à être engagée dans un trou réalisé dans la paroi du corps, créant ainsi le deuxième axe transversal (NN') de rotation desdites biellettes (14a, 14b).Figure 26 is a perspective illustration of another possibility of realization to realize the pivoting of the rods. According to this variant each of the rods includes a lower projection (15 ') intended to be engaged in a hole made in the wall of the body, thus creating the second transverse axis (NN ') of rotation of said links (14a, 14b).

    Notons que, comme cela est connu en soi, le corps (2) de la fixation est monté coulissant dans une glissière (51) fixée au ski pour permettre, d'une part, un réglage précis de sa position en fonction de la longueur de la chaussure de l'utilisateur et, d'autre part, son déplacement contre l'action d'un ou plusieurs ressort(s) (52). Par ailleurs, la fixation selon l'invention comprend avantageusement un frein de ski (70) escamotable.Note that, as is known per se, the body (2) of the binding is slidably mounted in a slide (51) fixed to the ski for allow, on the one hand, a precise adjustment of its position according to the length of the user's shoe and, on the other hand, its movement against the action of one or more spring (s) (52). Furthermore, fixing according to the invention advantageously comprises a ski brake (70) retractable.

    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 the modes of realization described and represented as examples, but it includes also all technical equivalents and their combinations.
