- the present invention relates to a safety ski binding comprising means for holding the heel and means for holding the front end of the boot, optionally mounted on an underfoot plate.
- the object of the present invention is to provide damping of vibrations, in particular longitudinal vibrations, in a safety ski binding of the type defined above without resorting to a particular assembly or a complex device.
- the invention also aims to maintain the overall flexibility of the ski.
- the safety binding according to the invention is characterized in that it comprises at least one damping element interposed between at least two existing parts of the binding which are not intimately linked so as to allow movements of small amplitude between these two parts.
- the damping element is preferably made of viscoelastic material.
- the damping element has the effect of filtering vibrations and absorbing the shocks usually transmitted from the ski to the boot.
- the damping element can be arranged inside the safety attachment.
- the damping element can in particular be interposed between two existing parts of the binding subjected to opposing longitudinal dynamic forces.
- any ski binding there is at least one place where the fact of inserting an elastic element makes it possible to obtain an advantageous damping effect which does not disturb the operation of the binding while absorbing the vibrations generated by the relative micro-displacements.
- the damping effect can therefore be obtained practically without modification of the fixing.
- the elastic element can in particular be placed at the level of the connection of the heel piece of the toe piece or of the underfoot plate to the ski.
- the damping element can be arranged between two parts of the plate, if the latter is in two parts, or in the device for adjusting the length of the plate in the case where such a adjustment is possible.
- the damping element can also be arranged between two vertically superimposed parts so as to damp vertical or oblique vibrations.
- Figure 1 is a longitudinal sectional view of an underfoot plate binding in which the damping element is disposed between the binding and its means of connection to the ski.
- Figure 2 is a detail of Figure 1.
- FIG. 3 is an alternative embodiment of the attachment shown in FIG. 1.
- Figure 4 shows the same attachment as Figure 1, with the damping element arranged in a different way.
- FIG. 5 is a view in longitudinal section of an attachment to an underfoot plate of the same type as that shown in FIG. 1.
- FIG. 6 shows a similar attachment to a telescopic plate and means for adjusting the length.
- FIG. 7 shows, in plan, the means for adjusting the fixing shown in FIG. 6 with a damping element.
- Figure 8 shows a front stop seen from below.
- FIG. 9 is a sectional view along IX-IX of FIG. 8.
- FIG. 1 represents a ski binding comprising an underfoot plate 11 made up of two parts 12 and 13 mounted telescopically.

- the front part 13 is provided at the front with a fixed stirrup 15 for holding the front end of the shoe.
- the underfoot plate 11 is pivotally mounted on the ski 6 by means of a pivot 16 secured to a base plate 17 screwed to the ski 6 by screws 18 and 19.
- the ends 17a and 17b of the base plate 17 are raised relative to the ski so as to constitute, with the ski, two slides in which the curved edges 20a and 20b engage of a plate 20 fixed to the underfoot plate 11.
- This plate 20 has a central hub 21 in which the pivot 16 is engaged with a longitudinal play towards the front and towards the rear.
- the plate 20 is also engaged with a large clearance on the ends 17a and 17b of the base plate 17, the space thus left being occupied by two linings 22 and 23 of viscoelastic material.
- the linings 22 and 23 coat the edges 20a and 20b so that a damping is obtained both in the vertical direction and in the longitudinal direction, that is to say a damping in practically all directions.
- rollers 25 and 26 being interposed between the base plate 17 and the plate 20 to facilitate rotation of the plate 20 on the plate 17.
- the bottom of the curved part 20 a is occupied by a viscoelastic lining 24 against which abuts the edge 17a of the plate 17.

- a viscoelastic damping element 28 is disposed between the rear part 12 of the underfoot plate and the rear end of the plate 20. Under the effect of a longitudinal shock, the rear part 12 of the plate may therefore move slightly longitudinally relative to the plate 20 and to the front part 13 of the plate.
- a second viscoelastic damping element similar to element 28 can be mounted between the front edge of the plate 20 and the part 13 of the underfoot plate.
- the damping element can also be arranged at the pivot 16.
- FIG. 5 The fixing is of the same type as the previous fixing, the two parts 12 ′ and 13 ′ of the plate under - telescopic stand differing only in details.
- the parts 12 ′ and 13 ′ of the sub-foot plate are fixed to the raised ends of a plate 29 to which are bent pieces 30 and 31 defining two slides in which the ends of the base plate 17 are engaged with interposition rollers 25 and 26 as in the embodiment shown in FIG. 4.

- the lining 34 is divided into two crescent-shaped linings arranged in front and behind the pivot 16.
- Figures 6 and 7 show a sub-foot plate attachment similar to the attachment shown in Figure 5, but additionally equipped with a device for adjusting its length.
- the adjustment device consists of an endless screw 35 cooperating with a rack 36, as described in patent application FR No. 89 14841 of the applicant.
- the two telescopic parts 12 ′ and 13 ′ of the sub-foot plate are again mounted on a plate 29.
- the rear part 12 ′ is fixed to the plate 29, while the front part 13 ′ can slide on this plate 29.
- the worm screw 35 is mounted at an angle between two brackets 37 and 38 fixed on the plate 29 and holding the worm screw 35 axially with the interposition of a damping element 39 in viscoelastic material between the end of the screw on the heel side and the 'square 37.
- the part 13 ′ of the sub-foot plate can thus move slightly towards the rear by driving the endless screw 35 which slightly compresses the damping element 39.
- the pivot 16 is provided with a sleeve 40 of self-lubricating material and the parts 12 ′ and 13 ′ of the underfoot plate are covered by a protective plate 41.

- the hollow body 43 is provided with two wings 46 and 47 connected to the body 43 by flexible arms 48, respectively 49.
- the wings 46 and 47 are further connected to each other by a transverse rod 50 having two threaded parts with opposite steps 50a and 50b.
- the non-threaded central part of the rod 50 is held axially on the body 43 by two flanges and a plate 51 welded to the body 43.

- the threaded part 50a is screwed into a cylindrical part with a vertical axis 52 fixed in a cylindrical housing by means of a cap 53 made of viscoelastic material.
- the threaded part 50b is screwed into a cylindrical part 54 fixed in a cylindrical housing of the wing 47 by means of a cap 55 of the same material as the cap 53.
- the wings 46 and 47 are therefore held in place by the rod 50 and the cylindrical parts 52 and 54, the rod 50 making it possible to modify the spacing of the wings to adapt it to the shoe.
- the caps 53 and 55 absorb, in all directions, the microvibrations transmitted by the ski and the body 43 to the shoe.
- the damping element also has the advantage of improving the flexibility of the ski under the binding, that is to say the overall flexibility of the ski. . Indeed, in such a binding, when the ski flexes, the distance between the front stop 15 ′ and the pivot 16 of the plate decreases.
- the heel spring can certainly absorb this shortening, but its strength is such that it modifies the flexibility of skiing.
- the damping element 39 makes it possible to overcome the spring by absorbing the variation in length resulting from the flexing of the ski.
- the damping element situated in the binding isolates the part situated upstream of this damper from the part situated downstream.

Abstract
Description
La présente invention concerne une fixation de ski de sécurité comprenant des moyens de maintien du talon et des moyens de maintien de l'extrémité avant de la chaussure, éventuellement montés sur une plaque sous-pied.The present invention relates to a safety ski binding comprising means for holding the heel and means for holding the front end of the boot, optionally mounted on an underfoot plate.
Afin d'améliorer le confort et la sécurité par élimination des micro-traumatismes dus aux chocs importants encaissés par les jambes d'un skieur lors du passage d'amas de neige durcie ou de bosses très rapprochées formant des ondulations très dures, il a été proposé d'intercaler entre le ski et chaque pied du skieur une sorte de suspension élastique sous forme de plaque élastique, de type ressort à lames, telle que décrite dans les brevets FR 2 347 066 et 2 338 720 ou sous forme d'une plaque élastique montée sur ressorts à boudin ou sur des tampons élastiques tels que décrits dans les documents FR 2 409 776, WO 86/04 824, DE 2 259 375 et CA 1 215 403. Les systèmes ont toutefois pour inconvénient de modifier la sensation du ski sous le pied en perturbant la transmission des efforts exercés sur le ski à la jambe et inversement, ce qui a pour conséquence une imprécision du guidage des skis.In order to improve comfort and safety by eliminating micro-trauma due to large shocks received by the legs of a skier during the passage of piles of hard snow or very close bumps forming very hard undulations, it was proposed to insert between the ski and each foot of the skier a kind of elastic suspension in the form of an elastic plate, of the leaf spring type, as described in the patents FR 2 347 066 and 2 338 720 or in the form of a plate elastic mounted on coil springs or on elastic pads as described in documents FR 2 409 776, WO 86/04 824, DE 2 259 375 and CA 1 215 403. The systems have the disadvantage, however, of modifying the feeling of skiing under the foot by disturbing the transmission of the forces exerted on the ski to the leg and vice versa, which results in imprecision in guiding the skis.
Pour la pratique du surf sur neige, il est connu de monter élastiquement la fixation, mais les conditions relatives au guidage et à la prise de virage sont très différentes de celles du ski.For the practice of snowboarding, it is known to mount the binding elastically, but the conditions relating to guiding and cornering are very different from those of skiing.
On a par ailleurs constaté que lorsque le skieur descend une piste, il se produit des micro-déplacements longitudinaux entre le ski et le skieur, dont la fréquence se traduit par des vibrations nuisibles.It has also been observed that when the skier descends a runway, longitudinal micro-displacements occur between the ski and the skier, the frequency of which results in harmful vibrations.
Il a été proposé, dans le brevet FR 2 646 093, d'intercaler des bandes de matériau élastique entre un corps de fixation et une glissière fixée au ski dans le but de combler le jeu vertical nécessaire au déplacement du corps dans la glissière et réduire ainsi l'usure. Ces bandes n'ont toutefois pas d'effet amortisseur sur les micro-déplacements longitudinaux.It has been proposed, in patent FR 2 646 093, to interpose strips of elastic material between a binding body and a slide fixed to the ski in order to fill the vertical clearance necessary for the movement of the body in the slide and reduce thus wear. These bands however have no damping effect on the longitudinal micro-displacements.
La présente invention a pour but d'assurer un amortissement des vibrations, notamment des vibrations longitudinales, dans une fixation de ski de sécurité du type défini plus haut sans faire appel à un montage particulier ou un dispositif complexe. L'invention a également pour but de conserver la flexibilité globale du ski.The object of the present invention is to provide damping of vibrations, in particular longitudinal vibrations, in a safety ski binding of the type defined above without resorting to a particular assembly or a complex device. The invention also aims to maintain the overall flexibility of the ski.
La fixation de sécurité selon l'invention est caractérisée en ce qu'elle comprend au moins un élément amortisseur intercalé entre au moins deux pièces existantes de la fixation non liées intimement de manière à autoriser des mouvements de faible amplitude entre ces deux pièces.The safety binding according to the invention is characterized in that it comprises at least one damping element interposed between at least two existing parts of the binding which are not intimately linked so as to allow movements of small amplitude between these two parts.
L'élément amortisseur est de préférence en matériau viscoélastique. L'élément amortisseur a pour effet de filtrer les vibrations et amortir les chocs habituellement transmis du ski à la chaussure.The damping element is preferably made of viscoelastic material. The damping element has the effect of filtering vibrations and absorbing the shocks usually transmitted from the ski to the boot.
D'une manière générale l'élément amortisseur peut être disposé à l'intérieur de la fixation de sécurité.In general, the damping element can be arranged inside the safety attachment.
L'élément amortisseur peut notamment être intercalé entre deux pièces existantes de la fixation soumises à des efforts dynamiques longitudinaux antagonistes. Dans toute fixation de ski, il existe au moins un endroit où le fait d'intercaler d'un élément élastique permet d'obtenir un effet amortisseur intéressant ne perturbant pas le fonctionnement de la fixation tout en absorbant les vibrations générées par les micro-déplacements relatifs. L'effet amortisseur peut donc être obtenu pratiquement sans modification de la fixation.The damping element can in particular be interposed between two existing parts of the binding subjected to opposing longitudinal dynamic forces. In any ski binding, there is at least one place where the fact of inserting an elastic element makes it possible to obtain an advantageous damping effect which does not disturb the operation of the binding while absorbing the vibrations generated by the relative micro-displacements. The damping effect can therefore be obtained practically without modification of the fixing.
L'élément élastique peut être en particulier placé au niveau de la liaison de la talonnière de la butée ou de la plaque sous-pied au ski. Dans une fixation à plaque sous-pied, l'élément amortisseur peut être disposé entre deux parties de la plaque, si celle-ci est en deux parties, ou dans le dispositif de réglage de la longueur de la plaque dans le cas où un tel réglage est possible.The elastic element can in particular be placed at the level of the connection of the heel piece of the toe piece or of the underfoot plate to the ski. In a sub-foot plate attachment, the damping element can be arranged between two parts of the plate, if the latter is in two parts, or in the device for adjusting the length of the plate in the case where such a adjustment is possible.
L'élément amortisseur peut également être disposé entre deux pièces superposées verticalement de manière à amortir des vibrations verticales ou obliques.The damping element can also be arranged between two vertically superimposed parts so as to damp vertical or oblique vibrations.
Le dessin annexé représente, à titre d'exemple, quelques formes d'exécution de l'invention.The accompanying drawing shows, by way of example, some embodiments of the invention.
La figure 1 est une vue en coupe longitudinale d'une fixation à plaque sous-pied dans laquelle l'élément amortisseur est disposé entre la fixation et ses moyens de liaison au ski.Figure 1 is a longitudinal sectional view of an underfoot plate binding in which the damping element is disposed between the binding and its means of connection to the ski.
La figure 2 est un détail de la figure 1.Figure 2 is a detail of Figure 1.
La figure 3 est une variante d'exécution de la fixation représentée à la figure 1.FIG. 3 is an alternative embodiment of the attachment shown in FIG. 1.
La figure 4 représente la même fixation que la figure 1, avec l'élément amortisseur disposé d'une manière différente.Figure 4 shows the same attachment as Figure 1, with the damping element arranged in a different way.
La figure 5 est une vue en coupe longitudinale d'une fixation à plaque sous-pied du même type que celle représentée à la figure 1.FIG. 5 is a view in longitudinal section of an attachment to an underfoot plate of the same type as that shown in FIG. 1.
La figure 6 représente une fixation analogue à plaque télescopique et moyen de réglage de la longueur.FIG. 6 shows a similar attachment to a telescopic plate and means for adjusting the length.
La figure 7 montre, en plan, les moyens de réglage de la fixation représentée à la figure 6 avec un élément amortisseur.FIG. 7 shows, in plan, the means for adjusting the fixing shown in FIG. 6 with a damping element.
La figure 8 représente une butée avant vue de dessous.Figure 8 shows a front stop seen from below.
La figure 9 est une vue en coupe selon IX-IX de la figure 8.FIG. 9 is a sectional view along IX-IX of FIG. 8.
La figure 1 représente une fixation de ski comprenant une plaque sous-pied 11 constituée de deux parties 12 et 13 montées de façon télescopique. Une telle fixation est décrite dans la demande de brevet FR 2 643 568 de la demanderesse. La partie postérieure 12 de la plaque porte une talonnière 14, par exemple une talonnière telle que décrite dans la demande de brevet FR 2 643 567 de la demanderesse. La partie antérieure 13 est munie à l'avant d'un étrier fixe 15 pour le maintien de l'extrémité avant de la chaussure. La plaque sous-pied 11 est montée pivotante sur le ski 6 au moyen d'un pivot 16 solidaire d'une plaque de base 17 vissée au ski 6 par des vis 18 et 19. Les extrémités 17a et 17b de la plaque de base 17 sont surélevées par rapport au ski de manière à constituer, avec le ski, deux glissières dans lesquelles viennent s'engager les bords recourbés 20a et 20b d'un plateau 20 fixé à la plaque sous-pied 11. Ce plateau 20 présente un moyeu central 21 dans lequel est engagé le pivot 16 avec un jeu longitudinal vers l'avant et vers l'arrière. Le plateau 20 est également engagé avec un jeu important sur les extrémités 17a et 17b de la plaque de base 17, l'espace ainsi laissé étant occupé par deux garnitures 22 et 23 en matériau viscoélastique. Dans la forme d'exécution représentée, les garnitures 22 et 23 enrobent les bords 20a et 20b de telle sorte que l'on obtient un amortissement aussi bien dans le sens vertical que dans le sens longitudinal, c'est-à-dire un amortissement dans pratiquement toutes les directions.FIG. 1 represents a ski binding comprising an
Il est toutefois possible de se contenter d'un amortissement longitudinal. Une telle variante est représentée à la figure 3, des rouleaux 25 et 26 étant interposés entre la plaque de base 17 et le plateau 20 pour faciliter la rotation du plateau 20 sur la plaque 17. Le fond de la partie recourbée 20 a est occupé par une garniture viscoélastique 24 contre laquelle vient s'appuyer le bord 17a de la plaque 17. Les autres extrémités de la plaque 17 du plateau 20 sont agencées de la même manière.It is however possible to be satisfied with a longitudinal damping. Such a variant is shown in FIG. 3,
La figure 5 représente une variante d'exécution de l'exécution représentée à la figure 3, dans laquelle le moyeu 21 du plateau 20 est monté sur le pivot 16 au moyen de rouleaux 27, c'est-à-dire sans jeu longitudinal. Un élément amortisseur viscoélastique 28 est disposé entre la partie postérieure 12 de la plaque sous-pied et l'extrémité postérieure du plateau 20. Sous l'effet d'un choc longitudinal, la partie postérieure 12 de la plaque pourra donc se déplacer légèrement longitudinalement relativement au plateau 20 et à la partie antérieure 13 de la plaque. Un second élément amortisseur viscoélastique analogue à l'élément 28 peut être monté entre le bord antérieur du plateau 20 et la partie 13 de la plaque sous-pied.5 shows an alternative embodiment of the embodiment shown in Figure 3, wherein the
L'élément amortisseur peut être également disposé au niveau du pivot 16. Un tel mode d'exécution est représenté à la figure 5. La fixation est du même type que les fixations précédentes, les deux parties 12′ et 13′ de la plaque sous-pied télescopique ne différant que par des détails. Les parties 12′ et 13′ de la plaque sous-pied sont fixées sur les extrémités relevées d'un plateau 29 auxquelles sont fixées des pièces coudées 30 et 31 définissant deux glissières dans lesquelles sont engagées les extrémités de la plaque de base 17 avec interposition de rouleaux 25 et 26 comme dans la forme d'exécution représentée à la figure 4. Une vis 32, fixée dans la plaque de base 17 et traversant une lumière en arc de cercle du plateau 29, limite la rotation de la plaque sous-pied. Le plateau 29 est muni d'un moyeu 33 par lequel il est monté sur le pivot 16. Entre le moyeu 33 et le pivot 16 est disposée une garniture viscoélastique 34 constituant l'élément amortisseur de la fixation.The damping element can also be arranged at the
Le moyeu 33 peut avoir la forme oblongue représentée à la figure 2. Dans ce cas, la garniture 34 est divisée en deux garnitures en forme de croissant disposées en avant et en arrière du pivot 16.The
Les figures 6 et 7 représentent une fixation à plaque sous-pied analogue à la fixation représentée à la figure 5, mais équipée en plus d'un dispositif de réglage de sa longueur. Le dispositif de réglage est constitué d'une vis sans fin 35 coopérant avec une crémaillère 36, comme décrit dans la demande de brevet FR N° 89 14841 de la demanderesse.Figures 6 and 7 show a sub-foot plate attachment similar to the attachment shown in Figure 5, but additionally equipped with a device for adjusting its length. The adjustment device consists of an
Les deux parties télescopiques 12′ et 13′ de la plaque sous-pied sont à nouveau montées sur un plateau 29. La partie postérieure 12′ est fixée sur le plateau 29, tandis que la partie antérieure 13′ peut coulisser sur ce plateau 29. La vis sans fin 35 est montée de biais entre deux équerres 37 et 38 fixées sur le plateau 29 et maintenant axialement la vis sans fin 35 avec interposition d'un élément amortisseur 39 en matériau viscoélastique entre l'extrémité de la vis côté talonnière et l'équerre 37. La partie 13′ de la plaque sous-pied peut ainsi se déplacer légèrement vers l'arrière en entraînant la vis sans fin 35 qui vient comprimer légèrement l'élément amortisseur 39.The two
Dans la forme d'exécution telle que représentée, le pivot 16 est muni d'un manchon 40 en matériau autolubrifiant et les parties 12′ et 13′ de la plaque sous-pied sont recouvertes par une plaque de protection 41. A la figure 8, on distingue la lumière 42 dont il a été question dans la description de la figure 5.In the embodiment as shown, the
La vis sans fin 35 peut bien entendu être remplacée par l'un des autres mobiles rotatifs décrits dans le demande de brevet FR 89 14841.The
Les moyens élastiques peuvent être également introduits dans une butée avant. Les figures 8 et 9 représentent une telle butée. Cette butée, vue de dessous à la figure 8, est constituée d'un corps métallique 43 fixé sur une plaque 44 elle-même fixée au ski 45 au moyen de vis. A la figure 8 la plaque 44 et le ski 45 sont représentés en traits fins comme s'ils étaient transparents. Le corps évidé 43 est muni de deux ailes 46 et 47 reliées au corps 43 par des bras flexibles 48, respectivement 49. Les ailes 46 et 47 sont en outre reliées entre elles par une tige transversale 50 présentant deux parties filetées de pas opposés 50a et 50b. La partie centrale non filetée de la tige 50 est maintenue axialement sur le corps 43 par deux collerettes et une plaque 51 soudée au corps 43. La tige 50 est munie à l'une de ses extrémités d'une tête 50c présentant une fente de vis. La partie filetée 50a est vissée dans une pièce cylindrique d'axe vertical 52 fixée dans un logement cylindrique par l'intermédiaire d'une coiffe 53 en matériau viscoélastique. De manière analogue, la partie filetée 50b est vissée dans une pièce cylindrique 54 fixée dans un logement cylindrique de l'aile 47 par l'intermédaire d'une coiffe 55 de même matériau que la coiffe 53.The elastic means can also be introduced into a front stop. Figures 8 and 9 show such a stop. This stop, seen from below in Figure 8, consists of a
Les ailes 46 et 47 sont donc maintenues en place par la tige 50 et les pièces cylindriques 52 et 54, la tige 50 permettant de modifier l'écartement des ailes pour l'adapter à la chaussure. Les coiffes 53 et 55 amortissent, dans toutes les directions, les microvibrations transmissent par le ski et le corps 43 à la chaussure.The
Il est possible de prévoir plusieurs éléments élastiques à différents endroits de la fixation.It is possible to provide several elastic elements at different locations of the fixing.
Dans certains modes de réalisation, notamment dans le mode de réalisation représenté à la figure 6, l'élément amortisseur a en outre pour avantage d'améliorer la flexibilité du ski sous la fixation, c'est-à-dire la flexibilité globale du ski. En effet, dans une telle fixation, lorsque le ski fléchit, la distance entre la butée avant 15′ et le pivot 16 de la plaque diminue. Le ressort de la talonnière peut certes absorber ce raccourcissement, mais sa force est telle qu'il modifie totalement la flexibilité du ski. L'élément amortisseur 39 permet de s'affranchir du ressort en absorbant la variation de longueur résultant de la flexion du ski.In certain embodiments, in particular in the embodiment shown in FIG. 6, the damping element also has the advantage of improving the flexibility of the ski under the binding, that is to say the overall flexibility of the ski. . Indeed, in such a binding, when the ski flexes, the distance between the
D'autre part, dans tous les systèmes décrits ci-dessus, l'élément amortisseur situé dans la fixation isole la partie située en amont de cet amortisseur de la partie située en aval.On the other hand, in all the systems described above, the damping element situated in the binding isolates the part situated upstream of this damper from the part situated downstream.
Autrement dit, toutes les vibrations générées par la piste qui sont transmises au ski se retrouvent bloquées par l'élément amortisseur et ne sont donc pas transmises au skieur.In other words, all the vibrations generated by the track which are transmitted to the ski are blocked by the damping element and are therefore not transmitted to the skier.
