Definitions
- the invention relates to a shoe retention element on a ski.
- the invention also relates to a pair of retaining elements.
- the invention relates to a front retaining element which is designed to releasably retain the front of a shoe by means of a movable retaining jaw against the restoring force of a spring. And among these retaining elements, the invention relates to an element which releases the shoe in a lateral direction asymmetrically, that is to say more easily on one side than on the other. It is in fact known that the leg of a skier, in particular at the knee, can endure higher torsional stresses for an outward rotation of the foot than for an inward rotation, that is to say ie towards the other foot.
- Front retaining elements with asymmetrical triggering are for example known from the French patent applications published under the number 1 503 847 or even the German patent applications published under the numbers 1 807 074 or 2 919 266.
- the latter two documents describe in particular retaining elements of the elastic stroke type, that is to say of which the retaining jaw is movable against the restoring force of an elastic restoring means which increases progressively with the angular displacement of said jaw .
- An object of the invention is to improve the operating mode of the asymmetrically triggered retaining elements, that is to say to improve their influence on the handling of the ski.
- the jaw has on each side an elastic stroke phase followed by a release phase.
- the jaw has a symmetrical behavior, that is to say that for the same angular movement it is recalled with the same force on one side and the other.
- the elastic running phase is shortened, that is to say that the shoe is released prematurely.
- the shoe does have a symmetrical foot hold.
- Figure 1 is a side view of a retainer.
- FIG. 2 is a side view in section through a longitudinal plane of the retaining element of FIG. 1.
- FIG. 3 is a top view in section through a horizontal plane of an upper level of the retaining element of FIG. 1.
- FIG. 4 is a top view in section through a horizontal plane of a lower level of the retaining element of FIG. 1.
- FIG. 5 illustrates an alternative embodiment
- FIG. 6 illustrates the operating mode of the element of FIG. 1.
- FIG. 7 illustrates an alternative embodiment of the element of FIG. 1.
- FIG. 8 is a bottom view of the base visible in FIG. 7.
- Figure 9 relates to an alternative embodiment of the invention.
- Figure 10 shows a top view and in section a retaining element according to another embodiment of the invention.
- FIG. 11 shows in exploded perspective the pivot and the tie rod of the element of FIG. 10.
- the retaining element shown in FIG. 1 comprises a base 2 surmounted by a body 3.
- the body has, seen from the side, a front part 3a secured to the base and an upper cover 3b.
- the retaining element further comprises a jaw 4.
- the jaw is composed of two lateral retaining wings of the shoe 5 and 6.
- the vertical retaining sole clamp here has two parts respectively associated with each of the wings.
- Each of the wings is articulated around a substantially vertical axis 7, 8.
- Each of the wings has, beyond the articulation axis, an extension 5a, 6a.
- the axes 7 and 8 are carried by a deformable parallelogram structure which comprises two arms 9 and 10 and on the side of the wings a cross member articulated to the arms around the axes 7 and 8 of articulation of the wings.
- the cross-member is in two superimposed parts 11 and 12.
- the arms are mobile in rotation around axes 13 and 14 carried by the base 2.
- the parallelogram structure is deformable against the elastic return force of a spring 16 housed in the body.
- the spring is retained at its front end by a plug screwed into the body. Its rear end bears against a piston 18 guided in a longitudinal orifice of the body.
- the piston is pushed against a ramp 20 located on the front edge of the cross member 11.
- the ramp is symmetrical with respect to a longitudinal and vertical plane defined by the ski. The trace of this plane is shown diagrammatically at 21 in FIG. 2.
- the spring opposes an identical restoring force whatever the direction in which the wings and the arms move.
- the wings are linked to the arms 9 and 10 and to the cross member 11 in an unlockable manner.
- the opening of the wings is controlled by a toggle 22 having two levers 23 and 24 hinged together in their central part around an approximately vertical axis.
- Each of the two levers is connected to a wing extension 5a, 5b.
- the length of the levers 23 and 24 is provided so that the toggle switch 22 in the flattened position maintains the two wings 5 and 6 substantially in the respective extension of the arms 9 and 10. This position is a stable position.
- the articulation zone of the toggle joint is in abutment against the cross-member 12, beyond the alignment of the articulation axes with the wing extensions.
- Each of the levers has on the outside a return 23a, 24a oriented substantially perpendicular to the general direction of each of the levers.
- the returns are approximately parallel and directed towards the front of the element.
- the returns are movable laterally with the deformation of the structure in parallelogram.
- a central stud 26 secured to the base 2 is provided to retain one or the other return beyond a determined displacement of the structure. This produces a break in the knee pad 22, and an opening of the wings, under the impulse of the shoe.
- the stud is here offset with respect to the median longitudinal axis 21 so that the breaking of the toggle joint occurs earlier on one side than on the other in the movement of the structure.
- the stud 26 is asymmetrical with respect to the line 21, it is offset towards the top of the figure, that is to say towards the right of the element of restraint. This means that the opening of the wings will occur earlier for a movement of the jaw down the figure, that is to say to the left of the element than in the opposite direction.
- FIG. 5 shows the retaining element with the jaw moved to the right of the element, this displacement having caused the breaking of the toggle joint 22.
- the jaw offers the same resistance to movement and acts with the same restoring force for a movement to the right or to the left of the median plane 21.
- the asymmetry comes from the fact that the opening of the wings intervenes for different displacement races, it intervenes earlier on the side where an anticipated release of the shoe is sought.
- the elastic restoring force that the shoe must overcome in order to achieve this anticipated release is lower on this side than on the other side, because the range of elastic travel is smaller.
- the shape of the ramp 20 could be adapted to this asymmetry, that is to say have an asymmetrical zone at the end of elastic travel, this zone taking into account the difference in amplitude of the two ranges of elastic travel.
- Figure 6 illustrates an alternative embodiment.
- the stud 36 which controls the opening of the toggle joint is placed symmetrically with respect to the median plane of symmetry, and it is the wing returns 31a and 32a of the levers 31 and 32 which are made asymmetrically .
- the wider return 32a would cause the toggle to open earlier than the return 31a.
- Figures 7 and 8 illustrate an improvement of this method of construction.
- the stud 34 which is in fact close to the level of the base 35, is mounted on a slider 36 movable in a transverse direction.
- the cursor is guided in a shouldered light directed in a transverse direction.
- the cursor is accessible under the base. It has two or three stable positions. In the two extreme positions, the stud is offset to one side or the other of the median vertical plane. This allows to polarize at will the retaining element as a right or left element and to modify this polarization if necessary.
- the cursor is no longer accessible once the retaining element has been assembled to a ski. Possibly there is a third stable position of the cursor where the pot is centered on the median longitudinal plane. In this position, the retainer operates symmetrically.
- FIG. 9 illustrates another embodiment of the invention.
- the retaining element which is represented conforms essentially to that which is described in the French patent application published under the number 2 625 443.
- This element comprises a base 41 surmounted by a body 42.
- the jaw has two retaining wings 43 and 44 which are articulated at the end of arms 45 and 46 around substantially vertical axes 47, 48.
- the arms are themselves articulated around substantially vertical axes 49, 50 located in the front part of the body and of the base.
- the arms each have a return 51, 52 bearing against a piston 53 guided in the body, and pushed forward by a spring 54.
- each wing The angular orientation of each wing relative to the arm which carries it is controlled by a ramp 55 against which wing extensions 43a, 44a, are supported.
- the ramp 55 has two parts for each of the wings. Each of these two parts comprises a substantially rectilinear and transverse zone 57a, 58a where the wing is held in the extension of the arm, and followed by a break 57b, 58b, where the wing has the possibility of opening much more than the arm, thus allowing the release of the shoe.
- FIG. 9 shows by way of illustration the arm 42 pressed against the body.
- the wing 44 has its extension 44a in abutment against the area 58a of the ramp.
- the arm 45 is separated from the body, the extension 43a of the wing 43 has reached the break 57b.
- the wing is more open than the arm, allowing the release of the shoe.
- This retaining element is made asymmetrical by the asymmetrical position of the breaks 57b and 58b relative to a vertical and longitudinal median plane materialized by its trace 60. It is visible in FIG. 9 that the break 58b is closer to this plane than the break 57b.
- the areas 57a and 58a are on the other hand of the same nature, so that the elastic return of the arms 45 and 46 is the same in the area of elastic travel where the wings recall the shoe in centered position.
- the ramp 55 is constructed symmetrically, and it is the wing extensions (43a, 44a) which are asymmetrical, in particular by different lengths.
- the wing with the shortest extension will more quickly reach the break of the ramp, i.e. its opening phase.
- Figure 10 shows another embodiment of the invention. This embodiment implements a retaining element which is essentially in accordance with that described in the French patent application published under the number 2 633 191.
- This element has a base 61 surmounted by a pivot 62.
- a body 63 is rotatably mounted around the pivot 62.
- the body itself carries a jaw having two wings 65 and 66 for lateral retention.
- the wings are movable relative to the body around vertical axes 67 and 68. Beyond the axes 67 and 68, the wings have wing returns 65a and 66a which are engaged with the head 78 of a tie 69 which passes through the pivot 62 and is guided in the body.
- a return spring 70 housed in the body opposes the longitudinal movement of the tie rod.
- the tie rod also carries integrally a lock 72 for blocking the body. The lock cooperates with a housing 73 of the pivot. It gradually emerges from this housing with the forward movement of the tie rod induced by an outward rotation of one of the wings. This disengagement movement corresponds to the elastic stroke phase where the jaw provides a refocusing of the shoe when the stress ceases.
- the lock is entirely released from its housing.
- the body is then unlocked, it rocks laterally around the pivot 62 thus allowing release of the shoe.
- the rear face of the pivot 62 has a small flat 75 against which a piston 76 pushed by the spring 70 bears.
- the rotation of the body is thus accompanied by additional compression of the spring which ensures the return to the initial position of the assembly, once the shoe has been released.
- the asymmetry here comes from the fact that the lock releases the body in a different manner depending on the direction in which the body is rotated by the shoe.
- the latch has on one side a milling or a chamfer 79.
- the latch is released for a smaller amplitude of movement on the side of the milling.
- the body releases the shoe more easily for a stress exerted on the wing located on the side of the milling.
- the milling or any other suitable means could be located on the pivot.
- this element is designed to be associated with another element which has an asymmetry of the same nature but opposite, so that the asymmetries and therefore the polarizations of the elements are opposite to each other.
- the retaining element could be equipped with other functions than the lateral release function which has been described, in particular a function for releasing the shoe in rear fall, a function for lightening the restoring force exerted by the spring on the jaw in the event of a front fall, an automatic height adjustment function, and any other existing function.

Abstract
Description
L'invention concerne un élément de retenue d'une chaussure sur un ski. L'invention concerne également une paire d'éléments de retenue.The invention relates to a shoe retention element on a ski. The invention also relates to a pair of retaining elements.
Plus exactement, l'invention concerne un élément de retenue avant qui est prévu pour retenir de façon libérable l'avant d'une chaussure au moyen d'une mâchoire de retenue mobile contre la force de rappel d'un ressort. Et parmi ces éléments de retenue, l'invention concerne un élément qui libère la chaussure selon une direction latérale de façon asymétrique, c'est-à-dire plus facilement d'un côté que de l'autre. Il est en effet connu que la jambe d'un skieur, en particulier au niveau du genou, peut endurer des contraintes de torsion plus élevées pour une rotation du pied vers l'extérieur que pour une rotation vers l'intérieur, c'est-à-dire vers l'autre pied.More precisely, the invention relates to a front retaining element which is designed to releasably retain the front of a shoe by means of a movable retaining jaw against the restoring force of a spring. And among these retaining elements, the invention relates to an element which releases the shoe in a lateral direction asymmetrically, that is to say more easily on one side than on the other. It is in fact known that the leg of a skier, in particular at the knee, can endure higher torsional stresses for an outward rotation of the foot than for an inward rotation, that is to say ie towards the other foot.
Des éléments de retenue avant à déclenchement dissymétrique sont par exemple connus d'après les demandes de brevet français publiées sous le numéro 1 503 847 ou encore les demandes de brevet allemands publiées sous les numéros 1 807 074 ou encore 2 919 266. Ces deux derniers documents décrivent en particulier des éléments de retenue du type à course élastique, c'est-à-dire dont la mâchoire de retenue est mobile contre la force de rappel d'un moyen de rappel élastique qui croît progressivement avec le déplacement angulaire de ladite mâchoire.Front retaining elements with asymmetrical triggering are for example known from the French patent applications published under the number 1 503 847 or even the German patent applications published under the numbers 1 807 074 or 2 919 266. The latter two documents describe in particular retaining elements of the elastic stroke type, that is to say of which the retaining jaw is movable against the restoring force of an elastic restoring means which increases progressively with the angular displacement of said jaw .
Ces éléments libèrent bien l'avant d'une chaussure de façon asymétrique, mais leur inconvénient est que l'asymétrie se manifeste dès le début de la rotation de la mâchoire, c'est-à-dire que dans la phase dite de course élastique qui précède la libération de la chaussure, l'avant de la chaussure est tenu de façon dissymétrique selon le sens de rotation, et qu'il est ramené de façon dissymétrique dans la position alignée sur le ski au cas où la sollicitation de la chaussure n'a pas été suffisante pour provoquer la libération. De tels éléments de retenue produisent une conduite de ski dissymétrique car ce qu'on a l'habitude d'appeler la tenue de pied est dissymétrique selon le sens de pivotement de la mâchoire. La tenue de pied désigne la capacité de la mâchoire à recentrer la chaussure pour des petites sollicitations.These elements release the front of a shoe asymmetrically, but their disadvantage is that the asymmetry manifests itself at the start of the rotation of the jaw, that is to say that in the phase known as elastic stroke. which precedes the release of the boot, the front of the boot is held asymmetrically according to the direction of rotation, and that it is brought back asymmetrically into the position aligned with the ski in the event that the solicitation of the boot n was not enough to bring about the release. Such retaining elements produce an asymmetrical ski pipe because what we used to call the foot support is asymmetrical according to the direction of pivoting of the jaw. Footwear refers to the ability of the jaw to refocus the shoe for small stresses.
Un but de l'invention est d'améliorer le mode de fonctionnement des éléments de retenue à déclenchement asymétrique, c'est-à-dire d'améliorer leur influence sur la conduite du ski.An object of the invention is to improve the operating mode of the asymmetrically triggered retaining elements, that is to say to improve their influence on the handling of the ski.
Selon l'invention, la mâchoire présente de chaque côté une phase de course élastique suivie d'une phase de libération. Dans les phases de course élastique, la mâchoire présente un comportement symétrique, c'est-à-dire que pour un même débattement angulaire elle est rappelée avec la même force d'un côté et de l'autre. Toutefois, d'un côté, la phase de course élastique est raccourcie, c'est-à-dire que l'on provoque de façon prématurée la libération de la chaussure.According to the invention, the jaw has on each side an elastic stroke phase followed by a release phase. In the phases of elastic stroke, the jaw has a symmetrical behavior, that is to say that for the same angular movement it is recalled with the same force on one side and the other. However, on the one hand, the elastic running phase is shortened, that is to say that the shoe is released prematurely.
Ainsi, la chaussure présente bien une tenue de pied symétrique.Thus, the shoe does have a symmetrical foot hold.
L'invention sera mieux comprise en se référant à la description ci-dessous et aux dessins en annexe qui en font partie intégrante.The invention will be better understood by referring to the description below and to the accompanying drawings which form an integral part thereof.

La figure 8 est une vue de dessous de l'embase visible en figure 7.FIG. 8 is a bottom view of the base visible in FIG. 7.
La figure 9 est relative à une variante de mise en oeuvre de l'invention.Figure 9 relates to an alternative embodiment of the invention.
La figure 10 représente en vue de dessus et en coupe un élément de retenue selon un autre mode de mise en oeuvre de l'invention.Figure 10 shows a top view and in section a retaining element according to another embodiment of the invention.
La figure 11 montre en perspective éclatée le pivot et le tirant de l'élément de la figure 10.FIG. 11 shows in exploded perspective the pivot and the tie rod of the element of FIG. 10.
L'élément de retenue représenté en figure 1 comprend une embase 2 surmontée d'un corps 3. Le corps présente vu de côté une partie avant 3a solidaire de l'embase et un capot supérieur 3b.The retaining element shown in FIG. 1 comprises a
L'élément de retenue comprend en outre une mâchoire 4. La mâchoire est composée de deux ailes de retenue latérale de la chaussure 5 et 6. Le serre-semelle de retenue verticale présente ici deux parties respectivement associées à chacune des ailes.The retaining element further comprises a jaw 4. The jaw is composed of two lateral retaining wings of the
Chacune des ailes est articulée autour d'un axe sensiblement vertical 7, 8. Chacune des ailes présente au-delà de l'axe d'articulation un prolongement 5a, 6a. Les axes 7 et 8 sont portés par une structure en parallélogramme déformable qui comprend deux bras 9 et 10 et du côté des ailes une traverse articulée aux bras autour des axes 7 et 8 d'articulation des ailes. La traverse est en deux parties superposées 11 et 12. A l'avant, les bras sont mobiles en rotation autour d'axes 13 et 14 portés par l'embase 2.Each of the wings is articulated around a substantially
La structure en parallélogramme est déformable contre la force de rappel élastique d'un ressort 16 logé dans le corps. Le ressort est retenu à son extrémité avant par un bouchon vissé dans le corps. Son extrémité arrière est en appui contre un piston 18 guidé dans un orifice longitudinal du corps. Le piston est repoussé contre une rampe 20 située sur le bord avant de la traverse 11. La rampe est symétrique par rapport à un plan longitudinal et vertical défini par le ski. La trace de ce plan est schématisée en 21 dans la figure 2. De cette façon, le ressort oppose une force de rappel identique quelque soit le sens dans lequel les ailes et les bras se déplacent.The parallelogram structure is deformable against the elastic return force of a
Les ailes sont liées aux bras 9 et 10 et à la traverse 11 de façon déverrouillable. En se référant en particulier à la figure 4, l'ouverture des ailes est contrôlée par une genouillère 22 ayant deux leviers 23 et 24 articulés entre eux dans leur partie centrale autour d'un axe approximativement vertical. Chacun des deux leviers est relié à un prolongement d'aile 5a, 5b. La longueur des leviers 23 et 24 est prévue pour que la genouillère 22 en position aplatie maintienne les deux ailes 5 et 6 sensiblement dans le prolongement respectif des bras 9 et 10. Cette position est une position stable. Par exemple, la zone d'articulation de la genouillère est en appui contre la traverse 12, au-delà de l'alignement des axes d'articulation aux prolongements d'aile.The wings are linked to the
Egalement il est possible de prévoir un petit ressort de torsion pour ramener la genouillère dans cette position stable en l'absence de chaussure.Also it is possible to provide a small torsion spring to bring the toggle back into this stable position in the absence of shoes.
Chacun des leviers présente sur l'extérieur un retour 23a, 24a orienté sensiblement perpendiculairement à la direction générale de chacun des leviers. En position aplatie de la genouillère, les retours sont approximativement parallèles et dirigés vers l'avant de l'élément. Les retours sont mobiles latéralement avec la déformation de la structure en parallélogramme.Each of the levers has on the outside a
Un plot central 26 solidaire de l'embase 2 est prévu pour retenir l'un ou l'autre retour au-delà d'un déplacement déterminé de la structure. Ceci produit une cassure de la genouillère 22, et une ouverture des ailes, sous l'impulsion de la chaussure.A
Le plot est ici décalé par rapport à l'axe longitudinal médian 21 pour que la cassure de la genouillère se produise plus tôt d'un côté que de l'autre dans le déplacement de la structure. En d'autres termes, en se reportant à la figure 4, le plot 26 est dissymétrique par rapport à la ligne 21, il est déporté vers le haut de la figure, c'est-à-dire vers la droite de l'élément de retenue. Cela signifie que l'ouverture des ailes se produira plus tôt pour un déplacement de la mâchoire vers le bas de la figure, c'est-à-dire vers la gauche de l'élément que dans le sens inverse. La figure 5 montre l'élément de retenue avec la mâchoire déplacée vers la droite de l'élément, ce déplacement ayant provoqué la cassure de la genouillère 22.The stud is here offset with respect to the median
De cette façon, contrairement aux éléments de retenue dissymétriques usuellement connus, sur la plage dite de course élastique, où la mâchoire a pour fonction de recentrer l'avant de la chaussure après un déplacement latéral de faible amplitude, la mâchoire offre la même résistance au déplacement et agit avec la même force de rappel pour un déplacement vers la droite ou vers la gauche du plan médian 21.In this way, unlike the asymmetrical retaining elements usually known, on the so-called elastic range, where the jaw has the function of refocusing the front of the shoe after a lateral displacement of low amplitude, the jaw offers the same resistance to movement and acts with the same restoring force for a movement to the right or to the left of the
L'asymétrie vient de ce que l'ouverture des ailes intervient pour des courses de déplacement différentes, elle intervient plus tôt du côté où une libération anticipée de la chaussure est recherchée. La force de rappel élastique que la chaussure doit vaincre pour atteindre cette libération anticipée est plus faible sur ce côté que sur l'autre côté, car la plage de course élastique est plus réduite. La forme de la rampe 20 pourrait être adaptée à cette asymétrie, c'est-à-dire présenter une zone asymétrique en fin de course élastique, cette zone tenant compte de la différence d'amplitude des deux plages de course élastique.The asymmetry comes from the fact that the opening of the wings intervenes for different displacement races, it intervenes earlier on the side where an anticipated release of the shoe is sought. The elastic restoring force that the shoe must overcome in order to achieve this anticipated release is lower on this side than on the other side, because the range of elastic travel is smaller. The shape of the
La figure 6 illustre une variante de réalisation. Selon cette variante, le plot 36 qui commande l'ouverture de la genouillère est placé de façon symétrique par rapport au plan de symétrie médian, et ce sont les retours d'ailes 31a et 32a des leviers 31 et 32 qui sont réalisés de façon dissymétrique. Dans le mode de réalisation illustré, le retour 32a, plus large, provoquerait l'ouverture de la genouillère plus tôt que le retour 31a.Figure 6 illustrates an alternative embodiment. According to this variant, the
Les figures 7 et 8 illustrent un perfectionnement de ce mode de construction. Selon ce perfectionnement, le plot 34, qui se trouve en fait près du niveau de l'embase 35, est monté sur un curseur 36 mobile selon une direction transversale. Par exemple, le curseur est guidé dans une lumière épaulée dirigé selon une direction transversale. Le curseur est accessible sous l'embase. Il présente deux ou trois positions stables. Dans les deux positions extrêmes, le plot se trouve décalé d'un côté ou de l'autre du plan vertical médian. Ceci permet de polariser à volonté l'élément de retenue en tant qu'élément droit ou gauche et de modifier le cas échéant cette polarisation. Il faut noter que le curseur n'est plus accessible une fois l'élément de retenue assemblé à un ski. Eventuellement il existe une troisième position stable du curseur où le pot est centré sur le plan longitudinal médian. Dans cette position, l'élément de retenue fonctionne de façon symétrique.Figures 7 and 8 illustrate an improvement of this method of construction. According to this improvement, the
La figure 9 illustre un autre mode de mise en oeuvre de l'invention. L'élément de retenue qui est représenté est conforme pour l'essentiel à celui qui est décrit dans la demande de brevet français publiée sous le numéro 2 625 443.FIG. 9 illustrates another embodiment of the invention. The retaining element which is represented conforms essentially to that which is described in the French patent application published under the
Cet élément comprend une embase 41 surmontée d'un corps 42. La mâchoire présente deux ailes de retenue 43 et 44 qui sont articulées à l'extrémité de bras 45 et 46 autour d'axes sensiblement verticaux 47, 48. Les bras sont eux mêmes articulés autour d'axes sensiblement verticaux 49, 50 situés dans la partie avant du corps et de l'embase. Les bras présentent chacun un retour 51, 52 en appui contre un piston 53 guidé dans le corps, et repoussé vers l'avant par un ressort 54.This element comprises a base 41 surmounted by a
L'orientation angulaire de chaque aile par rapport au bras qui la porte est contrôlée par une rampe 55 contre laquelle des prolongements d'aile 43a, 44a, sont en appui. La rampe 55 présente deux parties pour chacune des ailes. Chacune de ces deux parties comprend une zone sensiblement rectiligne et transversale 57a, 58a où l'aile est maintenue dans le prolongement du bras, et suivie par une cassure 57b, 58b, où l'aile a la possibilité de s'ouvrir beaucoup plus que le bras, permettant ainsi la libération de la chaussure. La figure 9 représente à titre d'illustration le bras 42 plaqué contre le corps. L'aile 44 a son prolongement 44a en appui contre la zone 58a de la rampe. Inversement, le bras 45 est écarté du corps, le prolongement 43a de l'aile 43 a atteint la cassure 57b. L'aile se trouve plus ouverte que le bras, permettant ainsi la libération de la chaussure.The angular orientation of each wing relative to the arm which carries it is controlled by a
Cet élément de retenue est rendu asymétrique par la position dissymétrique des cassures 57b et 58b par rapport à un plan vertical et longitudinal médian matérialisé par sa trace 60. Il est visible dans la figure 9 que la cassure 58b est plus proche de ce plan que la cassure 57b. Les zones 57a et 58a sont par contre de même nature, si bien que le rappel élastique des bras 45 et 46 est le même dans le domaine de course élastique où les ailes rappellent la chaussure en positon centrée.This retaining element is made asymmetrical by the asymmetrical position of the
Comme dans le cas précédent, il serait possible de rendre mobile selon une direction transversale le bloc qui porte la rampe 55, de façon à polariser à volonté l'élément de retenue comme un élément droit ou gauche, et éventuellement à rendre l'élément symétrique.As in the previous case, it would be possible to make mobile in a transverse direction the block which carries the
Selon une variante de ce mode de mise en oeuvre de l'invention, la rampe 55 est construite de façon symétrique, et ce sont les prolongements d'ailes (43a, 44a) qui sont dissymétriques, notamment par des longueurs différentes. Dans ce cas, l'aile qui présente le prolongement le plus court atteindra plus rapidement la cassure de la rampe, c'est-à-dire sa phase d'ouverture.According to a variant of this embodiment of the invention, the
La figure 10 représente un autre mode de réalisation de l'invention. Ce mode de mise en oeuvre met en oeuvre un élément de retenue qui est pour l'essentiel conforme à celui décrit dans la demande de brevet français publiée sous le numéro 2 633 191.Figure 10 shows another embodiment of the invention. This embodiment implements a retaining element which is essentially in accordance with that described in the French patent application published under the
Cet élément présente une embase 61 surmontée d'un pivot 62. Un corps 63 est monté rotatif autour du pivot 62. Le corps porte lui-même une mâchoire présentant deux ailes 65 et 66 de retenue latérale. Les ailes sont mobiles par rapport au corps autour d'axes verticaux 67 et 68. Au-delà des axes 67 et 68, les ailes présentent des retours d'aile 65a et 66a qui sont en prise avec la tête 78 d'un tirant 69 qui traverse le pivot 62 et est guidé dans le corps. Un ressort de rappel 70 logé dans le corps s'oppose au mouvement longitudinal du tirant. Le tirant porte par ailleurs de façon solidaire un verrou 72 de blocage du corps. Le verrou coopère avec un logement 73 du pivot. Il se dégage progressivement de ce logement avec le mouvement vers l'avant du tirant induit par une rotation vers l'extérieur de l'une des ailes. Ce mouvement de dégagement correspond à la phase de course élastique où la mâchoire assure un recentrage de la chaussure à la cessation de la sollicitation.This element has a base 61 surmounted by a
Au-delà d'une rotation déterminée de l'une des ailes, le verrou est entièrement dégagé de son logement. Le corps est alors déverrouillé, il bascule latéralement autour du pivot 62 permettant ainsi une libération de la chaussure.Beyond a determined rotation of one of the wings, the lock is entirely released from its housing. The body is then unlocked, it rocks laterally around the
De préférence, la face arrière du pivot 62 présente un petit méplat 75 contre lequel un piston 76 repoussé par le ressort 70 prend appui. La rotation du corps s'accompagne ainsi d'une compression additionnelle du ressort qui assure le retour en position initiale de l'ensemble, une fois la chaussure libérée.Preferably, the rear face of the
L'asymétrie vient ici du fait que le verrou libère de façon différente le corps selon le sens dans lequel le corps est sollicité en rotation par la chaussure.The asymmetry here comes from the fact that the lock releases the body in a different manner depending on the direction in which the body is rotated by the shoe.
Par exemple, comme cela est illustré, le verrou présente sur un côté un fraisage ou un chanfrein 79. Le verrou est libéré pour une amplitude de déplacement plus réduite du côté du fraisage. Le corps libère plus facilement la chaussure pour une sollicitation exercée sur l'aile située du côté du fraisage. En variante, le fraisage ou tout autre moyen approprié pourrait être situé sur le pivot.For example, as illustrated, the latch has on one side a milling or a
Comme les éléments de retenue précédemment décrits, cet élément est prévu pour être associé avec un autre élément qui présente une asymétrie de même nature mais inverse, de façon que les asymétries et donc les polarisations des éléments soient inverses l'une de l'autre.Like the previously described retaining elements, this element is designed to be associated with another element which has an asymmetry of the same nature but opposite, so that the asymmetries and therefore the polarizations of the elements are opposite to each other.
Naturellement, la présente description n'est donnée qu'à titre indicatif, et l'on pourrait adopter d'autres mises en oeuvre de l'invention sans pour autant sortir du cadre de celle-ci. En particulier, l'élément de retenue pourrait être équipé d'autres fonctions que la fonction de libération latérale qui a été décrite, notamment une fonction de libération de la chaussure en chute arrière, une fonction d'allègement de la force de rappel exercée par le ressort sur la mâchoire en cas de chute avant, une fonction de réglage hauteur automatique, et toute autre fonction existante.Naturally, the present description is given for information only, and other implementations of the invention could be adopted without departing from the scope thereof. In particular, the retaining element could be equipped with other functions than the lateral release function which has been described, in particular a function for releasing the shoe in rear fall, a function for lightening the restoring force exerted by the spring on the jaw in the event of a front fall, an automatic height adjustment function, and any other existing function.
