Description

La présente invention concerne une fixation de sécurité d'une chaussure sur un ski à mâchoires latérales, c'est-à-dire dans laquelles deux mâchoires latérales sont montées déplaçables parallèlement au plan du ski, sous l'effet d'un organe élastique, entre une position fermée pour laquelle elle coopère avec la semelle de la chaussure et une position ouverte pour laquelle celle-ci est complètement libérée.The present invention relates to a safety binding of a boot on a ski with lateral jaws, that is to say in which two lateral jaws are mounted movable parallel to the plane of the ski, under the effect of an elastic member, between a closed position for which it cooperates with the sole of the shoe and an open position for which the latter is completely released.

Le principe des fixations à mâchoires latérales est connu depuis plusieurs années, notamment par les brevets FR 1.411.638 et 2.021.237, mais n'ont jusqu'à présent pas fait l'objet de réalisations suffisamment satisfaisantes et sûres pour être commercialisées avec succès. Certaines améliorations ont été apportées par exemple pour éviter à l'utilisateur la nécessité de réarmer la fixation une fois que celle-ci a été déclenchée volontairement ou en cas de chute, comme décrit dans les brevets FR 2.332.773 et 2.445.730, ou pour améliorer le dégagement de la chaussure en cas d'ouverture de sécurité de la fixation, comme décrit dans le brevet FR 2.420.358.The principle of lateral jaw fasteners has been known for several years, in particular by patents FR 1,411,638 and 2,021,237, but until now have not been the subject of sufficiently satisfactory and safe embodiments to be successfully marketed . Certain improvements have been made for example to avoid the user having to rearm the binding once it has been released voluntarily or in the event of a fall, as described in the patents FR 2,332,773 and 2,445,730, or to improve the clearance of the shoe in the event of a secure opening of the binding, as described in patent FR 2,420,358.

Toutefois, les fixations à mâchoires latérales connues présentent toutes l'un ou plusieurs des inconvénients suivants : possibilité insuffisante de dégagement latéral de la chaussure,celui-ci étant entravé par la présence des mâchoires mêmes lorsque celles-ci sont en position ouvertes, trop grande complexité du système et par là prix de revient non compétitif, nécessité d'utiliser une plaque spéciale à fixer à la semelle de la chaussure, etc. Enfin, toutes les fixations connues fonctionnent avec des organes mobiles tels que coins, pentes, etc, qui sont en contact les uns avec les autres par frottement, ce qui tend à poser des problèmes à plus ou moins longue échéance lorsque l'usure commence à entraver le fonctionnement normal de ces organes mobiles.However, the known lateral jaw fasteners all have one or more of the following drawbacks: insufficient possibility of lateral release of the shoe, the latter being hampered by the presence of the jaws even when they are in the open position, too large complexity of the system and thereby uncompetitive cost price, need to use a special plate to fix to the sole of the shoe, etc. Finally, all known fasteners operate with movable members such as corners, slopes, etc., which are in contact with each other by friction, which tends to to pose problems in the more or less long term when wear begins to impede the normal functioning of these movable members.

En conséquence, un premier objet de cette invention tendant à remédier simultanément à tous inconvénients précités, consiste en une fixation du type mentionné ci-dessus et qui se caractérise par le fait que les mâchoires sont portées par des bras montés pivotants sur le ski et présentent vues en plan une forme générale conique s'évasant vers l'arrière, et par le fait que la portion de chaque mâchoire destinée à coopérer en position fermée avec la semelle de la chaussure forme une rampe faisant avec le plan du ski un angle aigu croissant d'avant en arrière.Consequently, a first object of this invention, which aims to remedy all the aforementioned drawbacks simultaneously, consists of a binding of the type mentioned above and which is characterized by the fact that the jaws are carried by arms pivotally mounted on the ski and have plan views a generally conical shape flaring backwards, and by the fact that the portion of each jaw intended to cooperate in the closed position with the sole of the boot forms a ramp forming with the plane of the ski an increasing acute angle back and forth.

Selon une réalisation particulière de l'invention, chaque mâchoire latérale est reliée à une tringle coulissant longitudinalement par des biellettes articulées entre elles, cette tringle étant elle-même soumise à l'action de l'organe élastique, par exemple un ressort fixé longitudinalement sur le ski en arrière des points de pivotement des bras portant les mâchoires. Dans cette réalisation, l'extrémité arrière de la tringle coopère avec une extrémité d'une bascule coudée dont l'autre extrémité est reliée par une biellette articulée à un piston soumis à l'action de l'organe élastique. La bascule présente dans ce cas deux positions stables correspondant aux positions respectivement ouverte et fermée des mâchoires.According to a particular embodiment of the invention, each lateral jaw is connected to a rod sliding longitudinally by connecting rods hinged together, this rod itself being subjected to the action of the elastic member, for example a spring fixed longitudinally on skiing behind the pivot points of the arms carrying the jaws. In this embodiment, the rear end of the rod cooperates with one end of a bent rocker, the other end of which is connected by a link articulated to a piston subjected to the action of the elastic member. The rocker has in this case two stable positions corresponding to the respectively open and closed positions of the jaws.

Enfin, un second objet de la présente invention consiste en une chaussure de ski destinée à être fixée sur un ski au moyen de la fixation de sécurité décrite précédemment, cette chaussure étant caractérisée par le fait qu'elle comporte une semelle dont la partie médiane présente des rebords latéraux de forme générale conique vus en plan et formant de chaque côté de la semelle une rampe faisant avec le plan de celle-ci un angle aigu croissant d'avant en arrière, ces rebords étant destinés à coopérer en position de service avec les mâchoires latérales de la fixation.Finally, a second object of the present invention consists of a ski boot intended to be fixed to a ski by means of the safety binding described above, this boot being characterized by the fact that it comprises a sole, the middle part of which has side edges of generally conical shape seen in plan and forming on each side of the sole a ramp forming with the plane thereof an increasing acute angle from front to back, these edges being intended to cooperate in the service position with the lateral jaws of the binding.

En référence tout d'abord aux figures 1 à 4, une première réalisation de la fixation de sécurité comporte deux plaques de base 1,2 fixées sur un ski 3 et entre lesquelles sont montées deux mâchoires latérales 4,4' déplaçables latéralement sous l'action d'un organe élastique contenu dans un boîtier 5 fixé sur le ski, l'organe élastique pouvant être actionné par un levier 6. Chaque mâchoire 4,4' comporte une portion 7,7' dirigée de bas en haut et de l'extérieur vers l'intérieur et faisant avec le plan du ski un angle aigu croissant d'avant en arrière de manière à conférer à cette portion une allure légèrement vrillée. L'angle minimum a peut être de l'ordre d'environ 300, alors que l'angle maximum β peut être de l'ordre d'environ 60°.Firstly referring to FIGS. 1 to 4, a first embodiment of the safety binding comprises two base plates 1, 2 fixed on a ski 3 and between which two jaws are mounted. 4,4 ′ lateral blades movable under the action of an elastic member contained in a housing 5 fixed on the ski, the elastic member being able to be actuated by a lever 6. Each jaw 4,4 ′ has a portion 7,7 'directed from bottom to top and from outside to inside and making with the ski plane an increasing acute angle from front to back so as to give this portion a slightly twisted appearance. The minimum angle a may be of the order of approximately 30 0 , while the maximum angle β may be of the order of approximately 60 °.

Selon une variante montrée en traits mixtes sur la figure 1, chaque mâchoire 4 peut présenter une portion médiante 7a évidée ne laissant que les deux portions externes 7b, 7c formant des sortes de griffes.According to a variant shown in phantom in Figure 1, each jaw 4 may have a recessed mediating portion 7a leaving only the two external portions 7b, 7c forming kinds of claws.

La première réalisation de la chaussure de ski 8 illustrée partiellement sur les figures 3 et 4 comporte une semelle 9, dont la partie médiane 10 présente des rebords latéraux 11,11' formant de chaque côté de la semelle une rampe faisant avec le plan de celle-ci un angle aigu croissant d'avant en arrière et lui conférant une forme correspondante à celle de l'espace compris entre les mâchoires 4,4' en position fermée. Ainsi, dans la position de service illustrée sur la figure 1, les mâchoires 4,4' épousent exactement les rampes latérales 11,11' de la partie médiane 10 de la semelle 9 de la chaussure 8.The first embodiment of the ski boot 8 partially illustrated in FIGS. 3 and 4 comprises a sole 9, the middle part 10 of which has lateral flanges 11, 11 ′ forming on each side of the sole a ramp forming with the plane of that -ci an increasing acute angle from front to back and giving it a shape corresponding to that of the space between the jaws 4,4 'in the closed position. Thus, in the service position illustrated in FIG. 1, the jaws 4, 4 'exactly match the lateral ramps 11, 11' of the middle part 10 of the sole 9 of the shoe 8.

En outre, pour assurer un dégagement latéral aisé de la chaussure 8 lorsque les mâchoires sont en position ouvertes, soit à la suite d'une chute, soit volontairement, la semelle 9 présente encore deux gorges transversales 12,13 délimitant respectivement vers l'avant et vers l'arrière la partie médiane lO. L'extrémité postérieure de cette partie médiane 10 présente en plus un retrait 14, situé sur l'axe longitudinal de la semelle et qui est destiné à coopérer, en position de service, avec un cône de centrage 15 fixé sur la plaque supérieure 2 de la fixation, en arrière par rapport aux mâchoires latérales 4,4' et sur l'axe longitudinal médiane du ski.In addition, to ensure easy lateral release of the shoe 8 when the jaws are in the open position, either following a fall, or voluntarily, the sole 9 still has two transverse grooves 12, 13 respectively delimiting forward and backwards the middle part 10. The rear end of this middle part 10 also has a recess 14, located on the longitu axis dinal of the sole and which is intended to cooperate, in the service position, with a centering cone 15 fixed on the upper plate 2 of the binding, behind with respect to the lateral jaws 4,4 'and on the median longitudinal axis ski.

Selon une variante illustrée en traits mixtes sur les figures 2 et 3, le rebord supérieur de la port- tion 7 de chaque mâchoire 4 peut présenter deux encoches ouvertes 50, de forme approximativement carrée ou rectangulaire, et dont les parois latérales internes sont évasées, avec des pentes d'environ 45°, de l'extérieur vers l'intérieur. Ces encoches 50 sont destinées à coopérer en position de service avec des taquets 51 de forme correspondante auxdites encoches. Avec cette variante, l'effort de torsion en cas de chute est mieux transmis aux mâchoires, et de plus le centrage de la chaussure est amélioré.According to a variant illustrated in dashed lines in FIGS. 2 and 3, the upper rim of the portion 7 of each jaw 4 may have two open notches 50, of approximately square or rectangular shape, the internal side walls of which are flared, with slopes of about 45 °, from outside to inside. These notches 50 are intended to cooperate in the service position with tabs 51 of shape corresponding to said notches. With this variant, the torsional force in the event of a fall is better transmitted to the jaws, and moreover the centering of the shoe is improved.

La semelle de la chaussure de ski destinée à être fixée au moyen de la fixation selon l'invention peut être venue d'une pièce de fabrication avec ses diverses caractéristiques décrites ci-dessus.The sole of the ski boot intended to be fixed by means of the binding according to the invention may have come from a workpiece with its various characteristics described above.

Un exemple de dispositif d'actionnement des mâchoires latérales 4,4' sera maintenant décrit en référence aux figures 5 à 8. Les mâchoires 4,4' dont la forme en plan est conique, s'évasant vers l'arrière, comporte en plus des portions vrillées 7,7' coopérant en position de service avec la semelle de la chaussure des portions horizontales 16, 16' constituant les prolongements de deux bras 17,17'. Ces bras 17, 17' sont montés pivotants sur la plaque 1 de la fixation sur des axes verticaux 18,18' , de telle sorte que les mâchoires 4,4' se déplacent par pivotement des bras 17,17' parallèlement à la surface du ski entre une position ouverte (figures 5 et 6) et une position fermée (figures 7A,7B et 8), les portions vrillées 7,7' des mâchoires 4,4' enserrant dans cette position fermée les rebords également vrillés de la portion médiane de la semelle de la chaussure.An example of a device for actuating the lateral jaws 4,4 'will now be described with reference to FIGS. 5 to 8. The jaws 4,4' whose planar shape is conical, widening towards the rear, also comprises twisted portions 7,7 'cooperating in the service position with the sole of the shoe horizontal portions 16, 16' constituting the extensions of two arms 17,17 '. These arms 17, 17 'are pivotally mounted on the plate 1 of the binding on vertical axes 18,18', so that the jaws 4,4 'move by pivoting the arms 17,17' parallel to the surface of the ski between an open position (Figures 5 and 6) and a closed position (Figures 7A, 7B and 8), the twisted portions 7,7 'of the jaws 4,4 'enclosing in this closed position the edges also twisted of the middle portion of the sole of the shoe.

Comme montré sur les figures 5 et 7A, une tringle 19 est montée coulissante longitudinalement entre les deux bras 17,17' portant les mâchoires 4,4', le mouvement de coulissement étant centré grâce à un téton 20 solidaire de la plaque 1 coopérant avec une fente longitudinale pratiquée dans cette tringle 19. L'extrémité antérieure de cette tringle 19 est reliée aux mâchoires latérales 4,4', plus particulièrement à leurs portions horizontales 16,16', au moyen de deux paires de biellettes 22,23; 22',23'. Chaque paire comprend une première biellette 22,22' dont une extrémité est articulée à l'extrémité de la tringle 19, l'autre extrémité de cette biellette 22,22' étant elle-même articulée sur une seconde biellette 23,23', laquelle est articulée sur la portion horizontale 16,16' de la mâchoire 4,4'. Les différentes articulations sont réalisées grâce à des axes de pivotement verticaux respectivement 24,24'; 25,25'; 26,26'. Enfin, le bord externe de chaque seconde biellette 23,23' est en contact avec un galet 27,27' fixé sur la plaque 1 et muni d'une bague tournante de manière à guider et à faciliter le passage d'une position à l'autre.As shown in FIGS. 5 and 7A, a rod 19 is slidably mounted longitudinally between the two arms 17, 17 'carrying the jaws 4.4', the sliding movement being centered by means of a stud 20 secured to the plate 1 cooperating with a longitudinal slot made in this rod 19. The front end of this rod 19 is connected to the lateral jaws 4,4 ', more particularly to their horizontal portions 16,16', by means of two pairs of rods 22,23; 22 ', 23'. Each pair comprises a first link 22,22 ', one end of which is articulated on the end of the rod 19, the other end of this link 22,22' being itself articulated on a second link 23,23 ', which is articulated on the horizontal portion 16,16 'of the jaw 4,4'. The various joints are produced by means of vertical pivot axes 24, 24 'respectively; 25.25 '; 26.26 '. Finally, the outer edge of each second link 23,23 'is in contact with a roller 27,27' fixed on the plate 1 and provided with a rotating ring so as to guide and facilitate the passage from one position to the 'other.

Comme montré sur les figures 6,7B et 8, la tringle 19 est reliée par son extrémité postérieure à un organe élastique constitué ici par un ressort 28 monté fixe par rapport au ski, longitudinalement en arrière de ladite tringle 19. Cette liaison est assurée par une bascule 29 dont l'une des extrémités coopère avec la tringle 19 et l'autre extrémité est reliée par une biellette 30 à un piston 31 solidaire du ressort 28. Plus particulièrement, et comme illustré sur la figure 7B, un axe transversal 32, fixé entre les extrémités correspondantes de deux bascules 29, 29' disposées latéralement parallèlement l'une à l'autre, coopère avec la gorge formée entre deux saillies transversales 33, 33' dont est munie l'extrémité postérieure de la tringle 19. De même, chacune des deux bascules 29, 29' est reliée au piston 31 par une biellettes 30, 30', un axe transversal 34 étant fixé à l'articulation entre les bascules 29, 29' et les biellettes 30, 30' et un axe transversal 35 dont les extrémités servent d'articulation aux biellettes 30, 30' coopère avec ledit piston 31. Une tige de guidage 36 est de plus fixée longitudinalement par l'une de ses extrémités au piston 31,passe à travers le ressort 28 et vient se loger par son autre extrémité librement dans un écrou de réglage 37, destiné à régler la force élastique du ressort 28 par vissage ou dévissage de celui-ci dans la paroi du boîtier 5. Enfin, l'axe transversal 38 reliant les portions coudées des deux bascules 29, 29' parallèles est pivoté dans les parois latérales du boîtier 5.As shown in FIGS. 6,7B and 8, the rod 19 is connected by its rear end to an elastic member constituted here by a spring 28 mounted fixed relative to the ski, longitudinally behind said rod 19. This connection is ensured by a lever 29, one of the ends of which cooperates with the rod 19 and the other end is connected by a link 30 to a piston 31 secured to the spring 28. More particularly, and as illustrated in FIG. 7B, a transverse axis 32, fixed between the corresponding ends of two rockers 29, 29 'arranged laterally parallel to one another, cooperates with the groove formed between two transverse projections 33, 33' which is provided with the rear end of the rod 19. Similarly, each of the two rockers 29, 29 'is connected to the piston 31 by a rods 30, 30', a transverse axis 34 being fixed to the articulation between the rockers 29, 29 'and the rods 30, 30' and a transverse axis 35 of which the ends serve as an articulation for the rods 30, 30 ′ cooperate with said piston 31. A guide rod 36 is moreover fixed longitudinally by one of its ends to the piston 31, passes through the spring 28 and is received by its other end freely in an adjustment nut 37, intended to adjust the elastic force of the spring 28 by screwing or unscrewing it in the wall of the housing 5. Finally, the transverse axis 38 connecting the bent portions of the two rockers 29 , 29 'parallel is pivoted in the par side of the housing 5.

Le mécanisme de liaison entre la tringle 19 et l'organe élastique 28 permet grâce à la présence des bascules 29, 29' de définir deux positions stables correspondant aux positions respectivement ouverte et fermée (figures 6 et 8) des mâchoires latérales 4, 4'.The linkage mechanism between the rod 19 and the elastic member 28 makes it possible, thanks to the presence of the latches 29, 29 ′, to define two stable positions corresponding to the respectively open and closed positions (FIGS. 6 and 8) of the lateral jaws 4, 4 ′ .

Comme illustré sur la figure 1, le levier de manipulation 6 est monté pivotant autour des extrémités de l'axe 38 à l'extérieur du boîtier 5, et est percé de chaque côté d'une ouverture 40 légèrement arquée dans laquelle se déplacent les extrémités de l'axe transversal 34 servant d'articulation entre les deux bascules 29, 29' et les deux biellettes 30, 30'.As illustrated in FIG. 1, the manipulation lever 6 is pivotally mounted around the ends of the axis 38 outside the housing 5, and is pierced on each side with a slightly arched opening 40 in which the ends move of the transverse axis 34 serving as an articulation between the two rockers 29, 29 'and the two links 30, 30'.

Le fonctionnement de la fixation de sécurité telle qu'elle vient d'être décrite en référence aux figures 1 à 8 est le suivant.The operation of the safety attachment as it has just been described with reference to Figures 1 to 8 is as follows.

La fixation de la chaussure 8 sur le ski 3 est obtenue en disposant celle-ci entre les mâchoires latérales 4,4' ouvertes, de telle sorte que la chaussure soit centrée grâce au cône de centrage 15 coopérant avec le retrait 14 correspondant pratiqué à l'arrière de la partie médiane 10 de la semelle 9. Puis il suffit de tirer sur le levier de tension 6 pour le lever et provoquer ainsi l'inversion de la position des bascules 29,29' ce qui provoque le déplacement vers l'arrière de la tringle 19 (voir figure 8) et par là la fermeture des mâchoires 4,4' sur la partie médiane 10 de la semelle 9 de la chaussure 8.The binding of the boot 8 on the ski 3 is obtained by placing the latter between the open side jaws 4, 4 ', so that the boot is centered by means of the centering cone 15 cooperating with the corresponding withdrawal 14 made at the 'rear of the middle part 10 of the sole 9. Then it is enough to pull on the tension lever 6 to lift it and thus cause the reversal of the position of the rockers 29,29' which causes the rearward movement of the rod 19 (see FIG. 8) and thereby the closing of the jaws 4,4 'on the middle part 10 of the sole 9 of the shoe 8.

La conception de la liaison tringle 19 - organe élastique 28 au moyen d'un système de bascule permettant un déplacement de l'axe d'appui de la biellette reliée audit organe élastique constitue un bras de levier se modifiant de manière graduelle, diminuant ainsi graduellement le moment de force nécessaire pour passer de la position ouverte à la position fermée et inver- sément. L'ouverture, respectivement la fermeture, des mâchoires est donc réalisée automatiquement immédiatement après le passage du point d'équilibre de la bascule (point d'inversion). On peut constater que le ressort 28 est moins comprimé en position de service (figure 8) qu'en position ouverte (figure 6), et par conséquent moins sollicité mécaniquement, ce qui tend à lui assurer un plus grande longévité.The design of the linkage rod 19 - elastic member 28 by means of a rocker system allowing a displacement of the support axis of the rod connected to said elastic member constitutes a lever arm modifying gradually, thus gradually decreasing the moment of force necessary to pass from the open position to the closed position and vice versa. The opening, respectively closing, of the jaws is therefore carried out automatically immediately after passing the balance point of the rocker (reversal point). It can be seen that the spring 28 is less compressed in the operating position (FIG. 8) than in the open position (FIG. 6), and therefore less stressed mechanically, which tends to give it greater longevity.

De plus, le système de biellettes 22,22';23,23' pour assurer la liaison entre l'extrémité avant de la tringle 19 et les mâchoires 4,4' permet une ouverture de celles-ci maximale pour un déplacement longitudinal très réduit de la tringle 19 et par là du ressort 28. Ceci est important pour permettre le dégagement complet de la chaussure lorsque les mâchoires sont en position ouvertes, soit par une manipulation volontaire du levier 6 obtenue en l'abaissant, par exemple en appuyant la pointe du bâton de ski dans l'encoche 41 prévue à cet effet à l'extrémité supérieure dudit levier 6 et en poussant vers le bas celui-ci, soit à cause d'une chute ayant conduit au fonctionnement du système de sécurité. En effet, la longueur de la partie médiane 10 de la semelle 9 étant inférieure à la distance minimale entre les mâchoires 4,4' en position ouverte, la chaussure 8 peut effectuer une rotation de 900 de chaque côté du ski au-dessus de ces mâchoires 4,4' grâce à la présence des gorges transversales 12,13 délimitant en avant et en arrière cette partie médiane lO. Il est ainsi remédié à l'un des plus graves inconvénients des fixations de sécurité à mâchoires latérales, le dégagement de la chaussure étant assuré dans n'importe quelle position.,In addition, the rod system 22.22 ';23.23' to ensure the connection between the front end of the rod 19 and the jaws 4.4 'allows a maximum opening of the latter for a very reduced longitudinal displacement. the rod 19 and thereby the spring 28. This is important to allow complete release of the shoe when the jaws are in the open position, either by voluntary manipulation of the lever 6 obtained by lowering it, for example by pressing the tip of the ski pole in the notch 41 provided for this purpose at the upper end of said lever 6 and pushing it down, either because of a fall leading to the operation of the security system. Indeed, the length of the middle part 10 of the sole 9 being less than the minimum distance between the jaws 4.4 'in the open position, the boot 8 can rotate 90 ° on each side of the ski above these jaws 4,4 'thanks to the presence of the transverse grooves 12,13 delimiting in front and in back this middle part lO. One of the most serious disadvantages of safety fasteners with side jaws is thus remedied, the release of the boot being ensured in any position.

En outre, l'utilisation de biellettes articulées permet d'obtenir une durée de vie supérieure du dispositif, les frottements étant nettement réduits par rapport aux systèmes connus.In addition, the use of articulated links makes it possible to obtain a longer service life of the device, the friction being markedly reduced compared to known systems.

Enfin, et surtout, la forme conique en plan des mâchoires 4,4' combinée avec la présence de rampes à angle variable d'avant en arrière permet de contrôler efficacement et simultanément les efforts de torsions latérales et de chute avant et arrière, ce qui n'est pas le cas avec les dispositifs connus du même type. Cet effet est encore amélioré par la présence de deux encoches ouvertes pratiquées dans le rebord supérieur de chaque mâchoire et des taquets de forme correspondante dont est munie la portion médiane de la semelle de la chaussure, comme décrit précédemment en variante. De plus, du fait de la présence d'un seul élément de centrage 15 coopérant avec un évidement 14 ouvert vers l'arrière de la partie médiane 10 de la semelle 9, la chaussure 8 peut le cas échéant, c'est-à-dire en cas de choc avant brusque dû par exemple à un impact frontal avec un obstacle caché, se dégager directement par glissement vers l'avant.Finally, and above all, the conical planar shape of the 4.4 'jaws combined with the presence of ramps at variable angle from front to back makes it possible to effectively and simultaneously control the forces of lateral torsion and of front and rear fall, which is not the case with known devices of the same type. This effect is further improved by the presence of two open notches made in the upper rim of each jaw and stoppers of corresponding shape with which the middle portion of the sole of the shoe is provided, as previously described as a variant. In addition, due to the presence of a single centering element 15 cooperating with a recess 14 open towards the rear of the middle part 10 of the sole 9, the shoe 8 can, where appropriate, that is to say say in the event of a sudden front impact due for example to a frontal impact with a hidden obstacle, disengage directly by sliding forward.

La seconde réalisation de la fixation selon l'invention représentée sur la figure 9 comporte deux plaques de base 101, 102 fixées sur un ski 103 et entre lesquelles sont montées deux mâchoires latérales 104, 104' déplaçables latéralement sous l'action d'un organe élastique contenu dans un boîtier 105 fixé sur le ski, l'organe élastique pouvant être actionné par exemple par un levier (non montré). Chaque mâchoire 104, 104' comporte une portion 106 dirigée de bas en haut et de l'extérieur vers l'intérieur et faisant avec le plan du ski un angle aigu croissant d'avant en arrière de manière à conférer à cette portion une allure légèrement vrillée. L'angle minimum (en avant) peut être de l'ordre d'environ 300, alors que l'angle maximum (vers l'arrière) peut être de l'ordre d'environ 60°.The second embodiment of the binding according to the invention shown in FIG. 9 comprises two base plates 101, 102 fixed on a ski 103 and between which are mounted two lateral jaws 104, 104 ′ which can be moved laterally under the action of a member elastic contained in a housing 105 fixed on the ski, the elastic member being able to be actuated for example by a lever (not shown). Each jaw 104, 104 ′ has a portion 106 directed from bottom to top and from the outside towards the inside and forming an acute angle increasing from front to back with the plane of the ski so as to give this portion a slightly twisted. The minimum angle (forward) can be on the order of about 30 ° , while the maximum angle (rearward) can be on the order of about 60 °.

Le dispositif d'actionnement (non illustré) des mâchoires latérales 104, 104' peut être, par exemple, le même que celui décrit précédemment en référence à la première forme d'exécution de l'invention.The actuating device (not illustrated) of the lateral jaws 104, 104 ′ may be, for example, the same as that described above with reference to the first embodiment of the invention.

De plus, entre les mâchoires latérales 104, 104' est disposé un organe de centrage constitué par une plaquette 107 présentant une empreinte conique 108 dont la pointe est dirigée vers l'avant du ski 103 et avec laquelle est destinée à coopérer, en position de service, la portion médiane 109 de la semelle 110 d'une seconde réalisation de la chaussure de ski 111 selon l'invention destinée à coopérer avec la fixation de sécurité ci-dessus.In addition, between the lateral jaws 104, 104 ′ is disposed a centering member constituted by a plate 107 having a conical imprint 108 whose tip is directed towards the front of the ski 103 and with which is intended to cooperate, in the position of service, the middle portion 109 of the sole 110 of a second embodiment of the ski boot 111 according to the invention intended to cooperate with the above safety binding.

Cette semelle 110, plus particulièrement illustrée sur les figures 11 à 16, peut être venue d'une seule pièce de fabrication en une matière plastique appropriée et comporte trois portions distinctes reliées les unes aux autres, à savoir une portion antérieure 112, une portion médianel09 et un talon 113, la liaison entre les trois portions consistant en des nervures 114, 114'. L'une ou l'autre de ces portions peut bien entendu également être simplement rapportée sur la surface inférieure de la chaussure.This sole 110, more particularly illustrated in FIGS. 11 to 16, may have come from a single production part made of an appropriate plastic material and has three distinct portions connected to each other, namely an ante portion lower 112, a middle portion 09 and a heel 113, the connection between the three portions consisting of ribs 114, 114 '. One or the other of these portions can of course also be simply attached to the lower surface of the shoe.

La partie médiane 109 de la semelle 110 présente des rebords latéraux supérieurs 115, 115' formant de chaque côté de cette partie médiane 109 une rampe dirigée de bas en haut de l'extérieur vers l'intérieur de celle-ci. Cette rampe forme avec le plan de la semelle un angle croissant d'avant en arrière et correspondant de chaque côté à la forme des mâchoires 104, 104' de la fixation (voir figures 11, 12, 14 et 15). De plus, chaque rampe 115, 115' présente une formation en saillie 116, 116' destinée à coopérer, en position de service, avec une encoche 106 de forme correspondante pratiquée dans l'arête supérieure de la portion vrillée 106 des mâchoires 104, 104'.The middle part 109 of the sole 110 has upper lateral edges 115, 115 ′ forming on each side of this middle part 109 a ramp directed from the bottom up from the outside towards the inside of the latter. This ramp forms with the plane of the sole an increasing angle from front to back and corresponding on each side to the shape of the jaws 104, 104 'of the binding (see Figures 11, 12, 14 and 15). In addition, each ramp 115, 115 'has a protruding formation 116, 116' intended to cooperate, in the service position, with a notch 106 of corresponding shape formed in the upper edge of the twisted portion 106 of the jaws 104, 104 '.

D'autre part, comme illustré sur les figures 11 et 13, la portion médiane 109 de la semelle 110 présente deux portions coniques de centrage 117, 118 respectivement à l'extrémité antérieure et postérieure de cette partie médiane 109. L'angle de chaque cône respectivement 117, 118 correspond aux angles respectifs correspondants de l'empreinte conique 108 de la plaquette 107 de lafixation de sécurité, lorsque la portion médiane 109 de la semelle 110 de la chaussure de ski 111 est en position de service entre les mâchoires 104, 104' de ladite fixation.On the other hand, as illustrated in FIGS. 11 and 13, the middle portion 109 of the sole 110 has two conical centering portions 117, 118 respectively at the front and rear ends of this middle portion 109. The angle of each cone respectively 117, 118 corresponds to the respective respective angles of the conical imprint 108 of the pad 107 of the safety fastening, when the middle portion 109 of the sole 110 of the ski boot 111 is in the service position between the jaws 104, 104 'of said fixing.

Ainsi, en position de service, la chaussure de ski 111 étant placée longitudinalement sur le ski 103, la portion médiane 109 de lasemelle 110 est serrée entre les mâchoires 104, 104' de la fixation, le dispositif de fermeture de celles-ci ayant été actionné. Dans cette position les mâchoires 104, 104' sont serrées sur les rebords 115, 116, 115', 116'de ladite portion médiane 109 alors que les portions coniques 117, 118 de celle-ci coopèrent avec l'empreinte conique 108 de la plaquette 107 de ladite fixation.Thus, in the service position, the ski boot 111 being placed longitudinally on the ski 103, the middle portion 109 of the sole 110 is clamped between the jaws 104, 104 'of the binding, the device for closing the latter having been operated. In this position the jaws 104, 104 ′ are clamped on the flanges 115, 116, 115 ′, 116 ′ of said central portion 109 while the conical portions 117, 118 of the latter cooperate with the conical imprint 108 of the plate 107 of said attachment.

Le fonctionnement de cette fixation en cas de chute du skieur est le même que celui décrit précédemment en référence à la première forme d'exécution. De plus, la présence de l'empreinte conique et des deux cônes de centrage de la semelle permet d'amorcer plus facilement le mouvement d'ouverture des mâchoires, et surtout provoque le dégagement de la chaussure vers le haut, sans risquer que celle-ci n'accroche les mâchoires de la fixation. Une parfaite sécurité tant pour l'ouverture des mâchoires que pour le dégagement complet de la chaussure est donc assuré.The operation of this binding in the event of the skier falling is the same as that described above with reference to the first embodiment. In addition, the presence of the conical imprint and the two centering cones of the sole makes it easier to initiate the opening movement of the jaws, and above all causes the shoe to be released upward, without risking that it does not hang the jaws of the binding. Perfect security both for opening the jaws and for the complete release of the shoe is therefore ensured.

Une variante de la seconde réalisation de la fixation selon l'invention, illustrée sur la figure 17, se distingue de celle-ci en ce que la plaquette avec empreinte conique est remplacée par quatre sabots de centrage 120, 121, 120', 121', fixés sur la face supérieure de la plaque de base 102 de la fixation dont seule une mâchoire latérale 104 est représentée. Chaque sabot 120, 121, 120' et 121' présente une face supérieure servant de rampe , la pente de cette rampe étant d'une part inclinée en direction de la surface supérieure de la plaque de base 102 de l'extérieur vers l'intérieur, et d'autre part légèrement inclinée vers le bas d'avant en arrière pour les sabots antérieurs 120, 120' et d'arrière en avant pour les sabots postérieurs 121, 121'.A variant of the second embodiment of the binding according to the invention, illustrated in FIG. 17, differs from this in that the plate with conical imprint is replaced by four centering shoes 120, 121, 120 ', 121' , fixed on the upper face of the base plate 102 of the binding of which only one side jaw 104 is shown. Each shoe 120, 121, 120 'and 121' has an upper face serving as a ramp, the slope of this ramp being inclined on the one hand towards the upper surface of the base plate 102 from the outside to the inside , and on the other hand slightly inclined downwards from front to back for the front shoes 120, 120 'and from back to front for the back shoes 121, 121'.

La variante illustrée sur la figure 17 est destinée à coopérer avec une semelle d'une chaussure de ski, telle qu'illustrée sur les figures 18 et 19, et qui comprend trois parties, respectivement une partie antérieure 122, un talon 123 et une partie médiane 124. De préférence, cette semelle est venue d'une pièce de fabrication en matière plastique, les trois parties constitutives étant réunies par des portions coniques 125, 126.The variant illustrated in FIG. 17 is intended to cooperate with a sole of a ski boot, as illustrated in FIGS. 18 and 19, and which comprises three parts, respectively a front part 122, a heel 123 and a part median 124. Preferably, this sole came from a plastic manufacturing part, the three parts constitutive being joined by conical portions 125, 126.

La partie médiane 124 de la semelle présente des rebords latéraux 127, 127' formant de chaque côté de cette partie une rampe dirigée de bas en haut de l'extérieur vers l'intérieur de celle-ci. Cette rampe forme avec le plan de la semelle un angle croissant d'avant en arrière et correspondant de chaque côté à la forme des mâchoires 104, 104' de la fixation (voir coupes des figures 20 et 21).The middle part 124 of the sole has lateral flanges 127, 127 ′ forming on each side of this part a ramp directed from the bottom upwards from the outside towards the inside thereof. This ramp forms with the plane of the sole an increasing angle from front to back and corresponding on each side to the shape of the jaws 104, 104 'of the binding (see sections of Figures 20 and 21).

En outre, comme indiqué précédemment, la portion médiane 124 est délimitée vers l'avant et vers l'arrière par deux portions transversales coniques 125, 126, dont les faces 128, 129, 128', 129' inclinées de bas en haut et du centre de la semelle vers l'extérieur de celle-ci correspondent aux faces supérieures des sabots de centrage 120, 121, 120', 121' avec lesquelles elles sont destinées à coopérer en position de service (voir figure 22).In addition, as indicated above, the middle portion 124 is delimited towards the front and towards the rear by two conical transverse portions 125, 126, whose faces 128, 129, 128 ', 129' inclined from bottom to top and from center of the sole towards the outside thereof correspond to the upper faces of the centering shoes 120, 121, 120 ', 121' with which they are intended to cooperate in the service position (see FIG. 22).

Ainsi, en position de service, les rebords latéraux 127, 127' de la partie médiane 124 de la semelle sont serrés par les mâchoires latérales 104, 104' de la fixation, et les faces 128, 129, 128', 129' des portions coniques transversales 125, 126 coopèrent avec les sabots de centrage respectifs 120, 121, 120', 121' de la fixation.Thus, in the service position, the lateral flanges 127, 127 'of the central part 124 of the sole are clamped by the lateral jaws 104, 104' of the binding, and the faces 128, 129, 128 ', 129' of the portions transverse conical 125, 126 cooperate with the respective centering shoes 120, 121, 120 ', 121' of the binding.

Le fonctionnement de cette variante est semblable à celui de la première décrite précédemment. Toutefois, dans ce cas, les mouvements de forces agissant par le centrage sont nettement supérieurs, étant donné que les portions coniques transversales coopérant - portions coniques de la semelle et sabots de centrage de la fixation - sont disposés à l'extérieur de la portion médiane de la semelle servant au serrage proprement dit par les mâchoires latérales, et non plus au-dessous comme décrit précédemment (voir schéma de la figure 23). De plus, les angles sont plus importants et le dégagement vertical de la chaussure lors d'une chute en torsion est nettement favorisé. La sécurité est donc encore augmentée. Enfin, la présence de cônes à l'avant et à l'arrière de la partie médiane de la semelle permet d'obtenir un centrage avant-arrière qui n'existait pas sur la réalisation précédente. De préférence, la partie médiane de la semelle de la chaussure selon l'invention, destinée à être serrée par les mâchoires latérales de la fixation, présente une longueur inférieure à la distance minimale entre ces mâchoires en position ouverte, de manière à permettre le dégagement complet de la chaussure même lorsque celle-ci est perpendiculaire à l'axe du ski.The operation of this variant is similar to that of the first described previously. However, in this case, the movements of forces acting by the centering are clearly greater, since the cooperating transverse conical portions - conical portions of the sole and centering shoes of the binding - are arranged outside the middle portion of the sole serving for the actual tightening by the lateral jaws, and no longer below as described previously (see diagram in Figure 23). In addition, the angles are greater and the vertical clearance of the shoe during a fall in torsion is clearly favored. Security is therefore further increased. Finally, the presence of cones at the front and at the rear of the middle part of the sole makes it possible to obtain a front-rear centering which did not exist in the previous embodiment. Preferably, the middle part of the sole of the shoe according to the invention, intended to be clamped by the lateral jaws of the binding, has a length less than the minimum distance between these jaws in the open position, so as to allow clearance full boot even when it is perpendicular to the axis of the ski.

Les figures 24 et 25 illustrent une butée réglable destinée à être disposée en avant des mâchoires (non montrées) de la seconde réalisation de la fixation selon l'invention. Cette butée réglable comporte un plot 130 solidaire de l'extrémité antérieure d'une lame 131 montée coulissante longitudinalement dans une ouverture axiale 132 prévue entre les deux plaques de base 101, 102 de la fixation. Cette lame 131 est munie de crans 133 destinés à coopérer avec un organe de verrouillage 134 actionnable depuis l'extérieur en vue de fixer la position longitudinale de la butée réglable. Ainsi, cette butée présente d'une part l'avantage de faciliter au skieur le chaussage de la fixation en déterminant la position avant contre laquelle doit être placée l'extrémité avant de la semelle de la chaussure et permet d'autre part, grâce à la forme extérieure aérodynamique donnée au plot 130 de faire dévier la neige sur les côtés et éviter l'accumulation de celle-ci contre la pointe de la chaussure.Figures 24 and 25 illustrate an adjustable stop intended to be disposed in front of the jaws (not shown) of the second embodiment of the binding according to the invention. This adjustable stop comprises a stud 130 secured to the front end of a blade 131 slidably mounted longitudinally in an axial opening 132 provided between the two base plates 101, 102 of the binding. This blade 131 is provided with notches 133 intended to cooperate with a locking member 134 operable from the outside in order to fix the longitudinal position of the adjustable stop. Thus, this stop has on the one hand the advantage of making it easier for the skier to put on the binding by determining the front position against which the front end of the sole of the shoe must be placed and, on the other hand, allows the aerodynamic outer shape given to the stud 130 to deflect the snow on the sides and avoid the accumulation of it against the tip of the shoe.

Enfin, la figure 26 illustre une troisième réalisation de la fixation selon l'invention, dans laquelle l'organe élastique contenu dans un boîtier 205 fixé sur le ski 203 et commandant l'ouverture et la fermeture des mâchoires 204 présentant des portions vrillées 207b, 207c est disposé en avant de celle-ci, c'est-à-dire en avant de la pointe de la chaussure de ski 208. Pour le reste, le fonctionnement de cette réalisation est le même que celui décrit en référence à la première forme d'exécution de la fixation selon l'invention. La bascule, dont les axes 234, 238 sont inversés par rapport à la première réalisation, est actionnée par le levier 206 et agit sur les bras (non montrés) pivotés entre les plaques de base 201, 202 en avant des mâchoires 204b, 204c et portant celles-ci.Comme précédemment, les mâchoires 204b, 204c coopèrent par serrage en position de service avec une rampe 211 que présente la portion médiane de la semelle de la chaussure de ski 208.Finally, FIG. 26 illustrates a third embodiment of the binding according to the invention, in which the elastic member contained in a housing 205 fixed to the ski 203 and controlling the opening and closing of the jaws 204 having twisted portions 207b, 207c is disposed in front of the latter, that is to say in front of the tip of the ski boot 208. For the rest, the operation of this embodiment is the same as that described with reference to the first embodiment of the binding according to the invention. The rocker, whose axes 234, 238 are reversed with respect to the first embodiment, is actuated by the lever 206 and acts on the arms (not shown) pivoted between the base plates 201, 202 in front of the jaws 204b, 204c and As before, the jaws 204b, 204c cooperate by tightening in the service position with a ramp 211 that has the middle portion of the sole of the ski boot 208.
