Le support est constitué de plusieurs éléments séparés qui sont montés sur le ski avec des espaces entre-eux et qui comportent chacun une plaque supérieure rigide ou semi-rigide (11, 14, 17) et une plaque inférieure élastique (13, 15, 18).The central ski binding with mounting support with separate elements has in its lower part pins (6, 7, 8, 9) which are intended to collaborate with corresponding openings (12, 16, 20) made in the elements constituting the support as well as screws (40) which are intended to collaborate with threads (10) made in the elements constituting the support. The support consists of several separate elements which are mounted on the ski with spaces between them and which each comprise a rigid or semi-rigid upper plate (11, 14, 17) and an elastic lower plate (13, 15, 18 ).

Description

La présente invention se rapporte à une fixation centrale de ski avec support de montage à éléments séparés et plus particulièrement à une fixation centrale destinée à être montée sur un support constitué de plusieurs éléments qui sont montés sur un ski.The present invention relates to a central ski binding with mounting support with separate elements and more particularly to a central binding intended to be mounted on a support consisting of several elements which are mounted on a ski.

La plupart des fixations centrales sont conçues de manière à être montées directement sur les skis avec des vis.Most central bindings are designed to be mounted directly on skis with screws.

Des formes d'exécutions avec des plaques de montage sont connues. Ces plaques sont destinées à être montées sur les skis et comportent des éléments de montage rapide, par exemple des ouvertures pour baïonnettes, qui sont destinés à collaborer avec des éléments correspondants montés sous la partie inférieure des fixations. Cette conception permet le montage et le démontage rapide des fixations. Le démontage rapide permet notamment de faciliter les opérations d'entretien des skis qui sont beaucoup plus aisées lorsque les fixations sont démontées. Le démontage des fixations permet également de faciliter le transport et le stockage des skis.Forms of execution with mounting plates are known. These plates are intended to be mounted on skis and include quick mounting elements, for example openings for bayonets, which are intended to collaborate with corresponding elements mounted under the lower part of the bindings. This design allows fast mounting and dismounting of fasteners. Quick disassembly makes it possible in particular to facilitate maintenance operations on skis which are much easier when the bindings are disassembled. Removing the bindings also makes it easier to transport and store the skis.

Toutefois les formes d'exécutions connues de plaques pour fixations centrales présentent plusieurs inconvénients dont le principal est constitué par le fait que ces plaques sont réalisées d'une seule pièce dont la longueur est sensiblement égale à la longueur hors tout de la fixation. Ces plaques sont soumises à des efforts importants, c'est-à-dire qu'elles nécessitent d'être réalisées avec des matériaux résistants, ce qui implique que ces plaques sont assez rigides. La portion du ski sur laquelle la plaque est montée est par conséquent rigidifiée ce qui a pour effet de modifier la courbe de flexion du ski, ce qui présente le désavantage important de modifier négativement les caractéristiques de skiabilité.However, the known embodiments of plates for central fasteners have several drawbacks, the main one being that these plates are made in one piece whose length is substantially equal to the overall length of the fastener. These plates are subjected to significant efforts, that is to say that they need to be made with resistant materials, which implies that these plates are fairly rigid. The portion of the ski on which the plate is mounted is therefore stiffened, which has the effect of modifying the flexion curve of the ski, which has the significant disadvantage of negatively modifying the skiability characteristics.

Les plaques en une pièce présentent encore l'inconvénient d'être d'un poids élevé.One-piece plates still have the disadvantage of being heavy.

Le but de la présente invention consiste donc à remédier aux inconvénients précités des formes d'exécutions connues. Le support de montage est constitué de plusieurs éléments séparés qui sont chacuns d'une longueur réduite. Avec cette conception le support de montage présente l'avantage important de ne pas rigidifier le ski et de ne pas modifier la courbe de flexion ce qui permet d'utiliser les caractéristiques de skiabilité du ski de manière optimale. La conception avec support en plusieurs éléments permet également d'obtenir un gain de poids important. Les éléments peuvent être montés sur des supports élastiques qui présentent l'avantage d'amortir les chocs et vibrations ce qui peut améliorer de manière assez importante les caractéristiques de skiabilité. Les supports élastiques peuvent être constitués par des plaques élastiques mais également par des plots élastiques qui présentent l'avantage de procurer un amortissement longitudinal et latéral. Les supports élastiques peuvent être réalisés en différentes épaisseurs selon les utilisateurs. Pour les moyens et bons skieurs une épaisseur importante, par exemple 4 à 5 mm, permet d'obtenir un amortissement important qui garantit un grand confort d'utilisation. Pour les très bons skieurs et compétiteurs un épaisseur réduite, par exemple 1 à 2 mm, permet d'obtenir un amortissement valable tout en conservant une grande précision de skiabilité . L'épaisseur des supports élastiques peut être différenciées, par exemple d'une épaisseur réduite dans la partie avant de la fixation et plus importante dans la partie arrière. Ces différences d'épaisseurs permettent de modifier l'angle formé par la semelle de la chaussure et la surface du ski, ce qui par exemple en ski de compétition peut permettre des réglages dans le but d'obtenir pour chacun une skiabilité optimale.The object of the present invention therefore consists in remedying the aforementioned drawbacks of the known embodiments. The mounting bracket consists of several separate elements, each of which is of reduced length. With this design, the mounting support has the important advantage of not stiffening the ski and of not modifying the bending curve, which makes it possible to use the skiability characteristics of the ski in an optimal manner. The design with support in several elements also allows to obtain a significant weight gain. The elements can be mounted on elastic supports which have the advantage of absorbing shocks and vibrations which can significantly improve the skiability characteristics. The elastic supports can be constituted by elastic plates but also by elastic studs which have the advantage of providing longitudinal and lateral damping. The elastic supports can be produced in different thicknesses according to the users. For the average and good skiers a significant thickness, for example 4 to 5 mm, makes it possible to obtain a significant damping which guarantees a great comfort of use. For very good skiers and competitors, a reduced thickness, for example 1 to 2 mm, makes it possible to obtain valid damping while retaining great skiability precision. The thickness of the elastic supports can be differentiated, for example a reduced thickness in the front part of the binding and greater in the rear part. These thickness differences make it possible to modify the angle formed by the sole of the boot and the surface of the ski, which for example in competition skiing can allow adjustments in order to obtain optimal skiability for each.

En référence tout d'abord à la figure 1, une fixation centrale 3 comporte des éléments d'accrochage latéraux 4 et 5 qui sont destinés à collaborer avec une empreinte 2 correspondante qui est montée dans une ouverture pratiquée dans la semelle d'une chaussure de ski 1, de manière à maintenir, en position de service, la chaussure sur la fixation. La fixation 3 est montée sur un support constitué par plusieurs éléments séparés qui comportent des plaques supérieures rigides ou semi-rigides 11, 14 et 17 qui sont assemblées, par collage par exemple, à des plaques inférieures élastiques, respectivement 13, 15 et 18 qui sont montées sur un ski 21. Les plaques supérieures comportent des ouvertures baïonnettes 12, 16, 19 et 20 qui sont destinées à collaborer avec des tourillons respectivement 6, 7, 8 et 9 qui sont montés sous la partie inférieure de la fixation 3, et des pas de vis 10 qui sont destinés à collaborer avec des vis 40 installées dans la fixation. Dans la pratique. le montage de la fixation s'effectue en introduisant les tourillons 6, 7, 8 et 9 dans la partie antérieure des ouvertures baïonnettes 12, 16, 19 et 20. La fixation est alors déplacée vers l'arrière de manière à ce que les tourillons soit introduits dans la partie postérieure des ouvertures baïonnettes, partie dans laquelle les tourillons sont maintenus verticalement. Dans cette position, les vis 40 sont introduites dans les pas de vis 10 de manière à maintenir la fixation longitudinalement. Le démontage de la fixation s'effectue en dévissant les vis 40 et en déplaçant la fixation vers l'avant jusqu'à ce que les tourillons se trouvent dans la portion des ouvertures baïonnettes qui permet leur dégagement vertical. Les plaques supérieures 11, 14 et 17 sont assemblées avec les plaques élastiques 13, 15 et 18 par collage par exemple.
Les plaques élastiques sont elle-mêmes montée sur le ski par collage, avec un adhésif double faces par exemple. Les plaques supérieures 11, 14 et 17 peuvent être réalisées avec des matériaux divers tels que, l'aluminium, les matériaux composites ou le plastique par exemple. Les plaques élastiques 13, 15 et 18 peuvent être réalisées en mousse synthétique ou en caoutchouc par exemple.Referring firstly to FIG. 1, a central binding 3 comprises lateral hooking elements 4 and 5 which are intended to collaborate with a corresponding imprint 2 which is mounted in an opening made in the sole of a shoe. ski 1, so as to maintain, in the service position, the boot on the binding. The fastener 3 is mounted on a support constituted by several separate elements which include rigid or semi-rigid upper plates 11, 14 and 17 which are assembled, by gluing for example, to elastic lower plates, respectively 13, 15 and 18 which are mounted on a ski 21. The upper plates have bayonet openings 12, 16, 19 and 20 which are intended to collaborate with pins respectively 6, 7, 8 and 9 which are mounted under the lower part of the binding 3, and screw threads 10 which are intended to collaborate with screws 40 installed in the binding. In practice. the mounting is mounted by inserting the pins 6, 7, 8 and 9 in the front part of the bayonet openings 12, 16, 19 and 20. The mounting is then moved backwards so that the pins are inserted into the rear part of the bayonet openings, part in which the pins are held vertically. In this position, the screws 40 are introduced into the threads 10 so as to maintain the fixing longitudinally. The fixing is dismantled by unscrewing the screws 40 and moving the fixing forward until the pins are in the portion of the bayonet openings which allows their vertical release. The upper plates 11, 14 and 17 are assembled with the elastic plates 13, 15 and 18 by gluing for example.
The elastic plates are themselves mounted on the ski by gluing, with a double-sided adhesive for example. The upper plates 11, 14 and 17 can be made with various materials such as aluminum, composite materials or plastic for example. The elastic plates 13, 15 and 18 can be made of synthetic foam or rubber for example.

Les figures 2 et 3 montrent en détail le support de montage constitué dans l'exemple présenté par trois éléments 11, 14 et 17 qui comportent des ouvertures baïonnettes 12, 16, 16′, 26, 26′ et 41 qui sont destinées à collaborer avec les tourillons montés sous la fixation. Les plaques supérieures 11, 14 et 17 sont montées respectivement sur des plaques élastiques 13, 15 et 18, elle-mêmes montées sur le ski 21. Les plaques 11, 14 et 17 sont destinées à être assemblées avec les plaques élastiques par collage par exemple et les plaques élastiques sont destinés à être montées sur le ski également par collage. Dans le cas des utilisations en compétition par exemple, les efforts transmis à la fixation et aux différents éléments constituant le support peuvent être très importants ce qui peut nécessiter un assurage par des vis 22, 24, 24′, 25, 25′, 26, 26′ et 27. L'élément central 14 du support de montage comporte des ouvertures baïonnettes dans sa partie postérieure et des pas de vis 23 et 23′ dans sa partie antérieure.Figures 2 and 3 show in detail the mounting support formed in the example presented by three elements 11, 14 and 17 which have bayonet openings 12, 16, 16 ′, 26, 26 ′ and 41 which are intended to collaborate with the pins mounted under the fixing. The upper plates 11, 14 and 17 are mounted respectively on elastic plates 13, 15 and 18, themselves mounted on the ski 21. The plates 11, 14 and 17 are intended to be assembled with the elastic plates by gluing for example and the elastic plates are intended to be mounted on the ski also by gluing. In the case of uses in competition for example, the forces transmitted to the fixing and to the various elements constituting the support can be very high which may require securing by screws 22, 24, 24 ′, 25, 25 ′, 26, 26 ′ and 27. The central element 14 of the mounting support comprises bayonet openings in its rear part and threads 23 and 23 ′ in its front part.

La figure 4 montre une forme d'exécution de support de montage constitué de plots élastiques. La fixation 3 comporte des tourillons 6, 7, 8 et 9 qui sont destinés à collaborer avec des ouvertures baïonnettes pratiquées dans des plots élastiques 28, 31, 32 et 33, et des vis 40 qui sont destinées à collaborer avec des pas de vis 10 pratiqués dans les plots 30. Le montage et le démontage de la fixation s'effectuent de la même manière que pour la forme d'exécution définie par la figure 1. La partie avant du support de montage comporte des plots 28 et 29 qui sont montés fixes sur une plaque 34 elle-même montée sur le ski 21. La partie centrale du support comporte les plots 30 et 31 qui sont montés fixes sur la plaque 35 elle-même montée sur le ski. Les plots 32 et 33 sont montés fixes sur la plaque 36 elle-même montée sur le ski. Les plaques 34, 35 et 36 sont montées sur le ski par collage ou par des vis par exemple. L'utilisation de plots élastiques présente l'avantage de procurer un amortissement vertical, longitudinal et latéral.FIG. 4 shows an embodiment of a mounting support made up of elastic studs. The fastening 3 comprises pins 6, 7, 8 and 9 which are intended to collaborate with bayonet openings made in elastic studs 28, 31, 32 and 33, and screws 40 which are intended to collaborate with threads 10 practiced in the studs 30. The mounting and dismounting of the fastening is carried out in the same way as for the embodiment defined in FIG. 1. The front part of the mounting support has studs 28 and 29 which are mounted fixed on a plate 34 itself mounted on the ski 21. The central part of the support includes the studs 30 and 31 which are fixedly mounted on the plate 35 itself mounted on the ski. The pads 32 and 33 are mounted fixed on the plate 36 itself mounted on the ski. The plates 34, 35 and 36 are mounted on the ski by gluing or by screws for example. The use of elastic studs has the advantage of providing vertical, longitudinal and lateral damping.

Les figures 5 et 6 montrent une forme d'exécution d'un support avec plots élastiques intégrés dans le ski. Les plots sont constitués par des éléments cylindriques élastiques dont la partie inférieure peut être introduite et fixée par collage, par exemple, dans un logement correspondant pratiqué dans le ski, ceci dans le cas où les plots sont destinés à être montés sur des skis conventionnels existants. La forme d'exécution présentée montre les plots 42, 42′ , 37, 37′, 38, 38′ et 39 qui comportent des ouvertures baïonnettes destinés à collaborer avec les tourillons de la fixation, les plots 43 et 43′ qui sont des plots d'appui, et les plots 44 et 44′ qui comportent des pas de vis destinés à collaborer avec les vis de la fixation. Dans le cas de skis destinés de fabrication à être utilisés avec une fixation centrale, les plots peuvent être intégrés aux skis directement lors du moulage des skis.Figures 5 and 6 show an embodiment of a support with elastic pads integrated in the ski. The pads are constituted by elastic cylindrical elements, the lower part of which can be introduced and fixed by gluing, for example, in a corresponding housing practiced in skiing, this in the case where the pads are intended to be mounted on existing conventional skis . The embodiment shown shows the studs 42, 42 ′, 37, 37 ′, 38, 38 ′ and 39 which have bayonet openings intended to collaborate with the pins of the fixing, the studs 43 and 43 ′ which are studs support, and the pads 44 and 44 ′ which include threads intended to collaborate with the screws of the fixing. In the case of skis intended for manufacture to be used with a central binding, the pads can be integrated into the skis directly when molding skis.

La forme des plots est indépendante du principe de l'invention, ceux-ci pouvant être de section carrée, rectangulaire, ou ovale par exemple. Les plots peuvent être réalisés dans des hauteurs diverses selon les utilisations prévues, une hauteur importante permettant un amortissement élastique important, la valeur de l'amortissement diminuant avec des hauteurs plus faibles. Des différences d'amortissement peuvent également être obtenues en utilisant des matériaux de fabrication plus ou moins élastiques. La hauteur des plots peut également être progressivement différente, par exemple une faible hauteur pour les plots disposés à l'avant et progressivement une hauteur plus importante pour les plots disposés à l'arrière, ceci pouvant permettre de varier la position de la fixation et par conséquent de la chaussure de ski par rapport à la surface du ski, c'est-à-dire par exemple que l'avant de la semelle de la chaussure se trouve à une hauteur plus faible que le talon, ceci par rapport à la surface du ski.The shape of the studs is independent of the principle of the invention, these may be of square, rectangular, or oval section for example. The studs can be made in various heights depending on the intended use, a large height allowing significant elastic damping, the value of the damping decreasing with lower heights. Differences in damping can also be obtained by using more or less elastic manufacturing materials. The height of the studs can also be progressively different, for example a small height for the studs arranged at the front and progressively a greater height for the studs arranged at the rear, this being able to allow the position of the fixing to be varied and by consequent of the ski boot relative to the ski surface, that is to say for example that the front of the sole of the boot is at a lower height than the heel, this relative to the surface ski.

Ces variations de hauteur et de matériaux sont également applicables pour les formes d'exécutions avec plaques élastiques.These variations in height and materials are also applicable for the forms of execution with elastic plates.

Les formes d'exécutions avec plaques élastiques montrent un support de montage avec trois éléments séparés. Le nombre d'éléments séparés n'est pas déterminant sur le principe de l'invention, le support pouvant aussi bien comporter deux ou quatres éléments séparés par exemple. Dans le cas des formes d'exécution avec plots élastiques, le nombre et la disposition des plots n'est pas déterminante sur le principe de l'invention. Les exemples présentés comportent onze plots à titre d'exemple. D'autres formes d'exécutions peuvent nécessiter moins ou plus de plots qui peuvent être disposés différemment.The execution forms with elastic plates show a mounting support with three separate elements. The number of separate elements is not decisive on the principle of the invention, the support being able to include two or four separate elements for example. In the case of embodiments with elastic studs, the number and arrangement of the studs is not decisive on the principle of the invention. The examples presented include eleven studs by way of example. Other forms of execution may require fewer or more studs which may be arranged differently.

Les tourillons sont montés dans les ouvertures correspondantes avec d'importants jeux de manière à permettre un déplacement qui peut être provoqué par la flexion des skis.The pins are mounted in the corresponding openings with large clearances so as to allow movement which can be caused by the bending of the skis.
