Description
DISPOSITIF DE FIXATION D'UNE CHAUSSURE SUR UN SORF A NEIGEDEVICE FOR FIXING A FOOTWEAR ON A SNOW SORF
La présente invention concerne un dispositif de fixa¬ tion d'une chaussure sur un surf à neige, et plus particu¬ lièrement un dispositif de fixation de sécurité, c'est-à- dire déclenchable en cas de chute, de choc ou de torsion, et qui comporte un système d'enclenchement automatique ("step-in"), ainsi qu'une chaussure de surf destinée à co¬ opérer avec ce dispositif de fixation.The present invention relates to a device for fixing a boot on a snowboard, and more particularly a safety binding device, that is to say triggerable in the event of a fall, impact or torsion. , and which includes an automatic engagement system ("step-in"), as well as a surf shoe intended to co¬ operate with this fastening device.
Actuellement, la pratique du surf ou planche à neige se fait généralement sans fixation de sécurité, contraire¬ ment à la pratique du ski alpin classique, en utilisant par exemple des étriers avant et arrière pour bloquer la chaussure sur la planche. Des fixations de sécurité pour surf à neige ont déjà été divulguées, par exemple dans le document FR-A-2.618.688, qui comportent par exemple sur un support lui-même fixé sur le surf une butée avant et une talonnière similaires à celles des fixations de sécurité des skis alpins conventionnels. De tels dispositifs pré¬ sentent les mêmes inconvénients que ceux prévus pour les skis alpins, à savoir une sécurité insuffisante en cas de choc dans l'axe butée/talonnière et la nécessité d'un ré¬ glage précis en fonction de la longueur de la semelle de la chaussure à fixer; de plus, la présence de deux dispo¬ sitifs mécaniques, respectivement avant et arrière, confère un poids supplémentaire non souhaité à la planche à neige.Currently, the practice of surfing or snowboarding is generally done without safety binding, contrary to the practice of classic alpine skiing, for example by using front and rear stirrups to block the boot on the board. Safety bindings for snowboarding have already been disclosed, for example in the document FR-A-2,618,688, which for example comprise on a support itself fixed on the boarding a front stop and a heel similar to those of Safety bindings for conventional alpine skis. Such devices pre¬ feel the same drawbacks as those provided for alpine skis, namely insufficient safety in the event of an impact in the toe / heel axis and the need for precise re-adjustment as a function of the length of the sole of the shoe to be fixed; in addition, the presence of two mechanical devices, respectively front and rear, gives additional undesired weight to the snowboard.
En conséquence, le but de la présente invention consiste à fournir un dispositif de sécurité pour la fixa¬ tion d'une chaussure sur un surf à neige qui ne présente
pas les inconvénients précités des dispositifs de fixation connus, permettant notamment d'utiliser le même dispositif de fixation pour des chaussures de longueurs différentes, sans nécessiter de réglage dudit dispositif, et qui com¬ porte en outre un système d'enclenchement automatique (ou step-in) .Consequently, the aim of the present invention is to provide a safety device for the fixation of a shoe on a snowboard which does not have not the aforementioned drawbacks of known fastening devices, making it possible in particular to use the same fastening device for shoes of different lengths, without requiring adjustment of said device, and which also carries an automatic engagement system (or step -in).
Le dispositif de fixation de sécurité d'une chaussure sur un surf à neige, qui constitue l'objet de la présente invention et vise à atteindre le but précité, présente les caractéristiques définies dans la revendication 1.The device for securing a boot securely to a snowboard, which is the object of the present invention and aims to achieve the above object, has the characteristics defined in claim 1.
Un second objet de l'invention consiste en une chaus¬ sure de surf destinée à être fixée sur un surf à neige au moyen du dispositif de fixation de sécurité selon l'inven¬ tion, et qui présente les caractéristiques énumérées dans la revendication 7.A second object of the invention consists of a surf shoe intended to be fixed to a snowboard by means of the safety fixing device according to the invention, and which has the characteristics listed in claim 7.
L'invention sera décrite ci-après en détails, et en référence au dessin annexé. Ce dessin illustre schémati- quement et à titre d'exemple une forme d'exécution parti¬ culière de l'invention.The invention will be described below in detail, and with reference to the accompanying drawing. This drawing illustrates schematically and by way of example a particular embodiment of the invention.
La figure 1 en est une vue en plan, et la figure 2 une vue de face, montrant également la portion de la semelle de la chaussure fixée.Figure 1 is a plan view, and Figure 2 a front view, also showing the portion of the sole of the shoe attached.
Les figures 3 et 4 en sont des vues partiellement en coupe horizontale, respectivement verticale, en position de service fermée.Figures 3 and 4 are views partially in horizontal section, respectively vertical, in the closed service position.
Les figures 5 et 6 en sont des vues partiellement en coupe horizontale, respectivement verticale, en position hors-service ouverte.Figures 5 and 6 are views partially in horizontal section, respectively vertical, in the open out-of-service position.
En référence tout d'abord aux figures 1 et 2, la forme d'exécution du dispositif de fixation selon l'invention
O 96/03185 PCMB95/00493Referring first to Figures 1 and 2, the embodiment of the fixing device according to the invention O 96/03185 PCMB95 / 00493
- 3 -- 3 -
illustrée à titre d'exemple comporte un boîtier 1, renfer¬ mant le mécanisme de fonctionnement de la fixation, et destiné à être fixé sur la surface supérieure S d'un surf ou planche à neige, et deux mâchoires latérales 2 action¬ nées par ledit mécanisme et munies chacune de griffes ou doigts d'accrochage 3; ces griffes 3 sont destinées à en¬ serrer en position de service fermée une empreinte ou por¬ tion profilée C faisant partie de la semelle de la chaus¬ sure à fixer (non montrée) ou rapportée sous celle-ci (voir figure 2) .illustrated by way of example comprises a housing 1, containing the operating mechanism of the binding, and intended to be fixed to the upper surface S of a snowboard or snowboard, and two lateral jaws 2 actioned by said mechanism and each provided with hooking claws or fingers 3; these claws 3 are intended to en¬ clamp in the closed service position an imprint or profiled por¬ tion C forming part of the sole of the shoe to be fixed (not shown) or attached thereto (see FIG. 2).
En pratique, deux dispositifs de fixation tels que celui illustré sur la figure 1 sont fixés sur le surf, parallèlement l'un à l'autre ou non, et selon un angle par rapport à l'axe longitudinal audit surf dépendant de ma¬ nière connue en soi des impératifs de la pratique de ce sport et des choix de l'utilisateur. Des moyens peuvent également être prévus entre le boîtier 1 et la surface S du surf pour permettre un réglage facilité de la position de chacun des deux dispositifs de fixation, notamment de l'angle précité.In practice, two fastening devices such as that illustrated in FIG. 1 are fixed to the surf, parallel to one another or not, and at an angle relative to the longitudinal axis of said surf depending on ma¬ manner known per se of the imperatives of the practice of this sport and the choices of the user. Means can also be provided between the housing 1 and the surface S of the surf to allow easy adjustment of the position of each of the two fastening devices, in particular the aforementioned angle.
Dans la position ouverte (traits mixtes), les m⬠choires latérales 2 ne maintiennent par contre plus entre elles la portion profilée C de la semelle de la chaussure. Le déplacement entre ces deux positions, respectivement fermée et ouverte, est provoqué par l'action d'un organe élastique 4 d'accumulation d'énergie disposé de préférence en avant des mâchoires 2.In the open position (dashed lines), the lateral jaws 2 no longer hold against each other the profiled portion C of the sole of the shoe. The displacement between these two positions, respectively closed and open, is caused by the action of an elastic member 4 of energy accumulation preferably arranged in front of the jaws 2.
On décrira maintenant, en référence aux figures 3 à 6, le mécanisme de fonctionnement du dispositif de fixation
O 96/03185 PCMB95/00493We will now describe, with reference to Figures 3 to 6, the operating mechanism of the fixing device O 96/03185 PCMB95 / 00493
- 4 -- 4 -
selon l'invention visant à passer de la position ouverte des mâchoires (position hors-service) à celle fermée (po¬ sition de service).according to the invention to move from the open position of the jaws (out of service position) to that closed (po¬ sition service).
L'action de l'ensemble du mécanisme est donc provoquée par un organe élastique représenté ici par un ressort 4 disposé en avant des mâchoires 2, et dont la force peut être ajustée par une vis de réglage 5. Ce ressort 4 agit sur les mâchoires latérales 2 par l'entremise d'un système de "bascule", destiné à définir deux positions stables du dispositif, correspondant aux positions ouverte et fermée des mâchoires 2, au-delà d'un "point mort" situé entre ces deux positions. Plus particulièrement, un double levier d'enclenchement 6 est monté pivotant sur un axe 7 horizon¬ tal et transversal, fixé latéralement par exemple dans les parois latérales du boîtier 1. Ce levier d'enclenchement 6 servant d'organe de "bascule" est relié vers l'avant par l'entremise d'une bielette axiale 8 à une tringle axiale 9 prolongeant l'organe élastique 4. Cette tringle 9 présente une ouverture 10 de guidage axial coopérant avec un axe vertical fixe 11, ici une vis de montage du dispositif. D'autre part le levier d'enclenchement 6 est relié vers l'arrière à un organe de manoeuvre 12 monté pivotant sur un axe 13 horizontal et transversal, fixé latéralement par exemple dans les parois latérales du boîtier 1, par l'en¬ tremise d'une bielette droite 14; l'organe de manoeuvre est lui-même commandé par un levier à main 14 prolongeant vers l'extérieur l'axe de pivotement transversal 13.The action of the entire mechanism is therefore caused by an elastic member represented here by a spring 4 disposed in front of the jaws 2, and the force of which can be adjusted by an adjusting screw 5. This spring 4 acts on the jaws lateral 2 by means of a "rocker" system, intended to define two stable positions of the device, corresponding to the open and closed positions of the jaws 2, beyond a "dead center" located between these two positions. More particularly, a double interlocking lever 6 is pivotally mounted on a horizontal and transverse axis 7, fixed laterally for example in the side walls of the housing 1. This interlocking lever 6 serving as a "rocker" member is forwardly connected via an axial link 8 to an axial rod 9 extending the elastic member 4. This rod 9 has an opening 10 for axial guide cooperating with a fixed vertical axis 11, here a mounting screw of the device. On the other hand the engagement lever 6 is connected rearwardly to an operating member 12 pivotally mounted on a horizontal and transverse axis 13, fixed laterally for example in the side walls of the housing 1, by the inlet a straight rod 14; the operating member is itself controlled by a hand lever 14 extending outward the transverse pivot axis 13.
D'autre part, chaque mâchoire 2 est articulée sur un bras 15 au moyen d'un téton d'articulation 16 vertical, l'extrémité libre du bras 15 étant monté pviotant sur un
pivot vertical 17 solidaire du dispositif, de telle sorte que ladite mâchoire 2 puisse pivoter dans le plan horizon¬ tal. L'articulation en 16 de la mâchoire 2 à l'extrémité de son bras support 15 est limitée dans son pivotement vers l'extérieur par un epaulement 18 que présente ladite mâchoire à son extrémité postérieure, cet epaulement 18 venant en butée contre ledit bras 15 lors de l'ouverture de la fixation et ceci après rattrapage d'un pas de fonc¬ tionnement.On the other hand, each jaw 2 is articulated on an arm 15 by means of a vertical hinge pin 16, the free end of the arm 15 being mounted pivoting on a vertical pivot 17 secured to the device, so that said jaw 2 can pivot in the horizontal plane. The articulation at 16 of the jaw 2 at the end of its support arm 15 is limited in its pivoting towards the outside by a shoulder 18 which said jaw has at its rear end, this shoulder 18 abutting against said arm 15 during the opening of the binding and this after catching a functional step.
Enfin, la liaison mécanique entre l'organe "bascule" 6, lui-même asservi à l'organe élastique 4, est assurée par une double tringle horizontale 19 solidaire en trans¬ lation axiale du double levier d'enclenchement 6 et reliée à une bielette triangulaire 20 horizontale par une bi¬ elette droite 21 , cette bielette triangulaire 20 présen¬ tant une ouverture allongée 22 avec laquelle coopère un téton d'articulation 23 solidaire de la mâchoire 2.Finally, the mechanical connection between the "rocker" member 6, itself slaved to the elastic member 4, is provided by a horizontal double rod 19 secured in axial trans¬ lation to the double engagement lever 6 and connected to a triangular connecting rod 20 horizontal by a straight rod 21, this triangular connecting rod 20 presenting an elongated opening 22 with which an articulation stud 23 fixed to the jaw 2 cooperates.
Ainsi, au mouvement de translation vers l'arrière du dispositif de la tringle 9, sous l'action du ressort 4 par exemple, correspond un mouvement d'ouverture des mâchoires 2. Comme déjà mentionné, l'organe "bascule", constitué par le levier d'enclenchement 6, permet de définir deux posi¬ tions stables du mécanisme, une première position ouverte (hors-service) correspondant à celle illustrée sur les figures 5 et 6, et une seconde position fermée ou de ser¬ vice correspondant à celle des figures 3 et 4. Pour passer d'une des positions à l'autre (passage du "point mort") contre l'action du ressort 4, il convient d'agir sur le levier d'enclenchement 6 soit directement, soit indirecte-
ment.Thus, the movement of translation towards the rear of the rod device 9, under the action of the spring 4 for example, corresponds to an opening movement of the jaws 2. As already mentioned, the "rocker" member, constituted by the engagement lever 6, makes it possible to define two stable positions of the mechanism, a first open position (out of service) corresponding to that illustrated in FIGS. 5 and 6, and a second closed or service position corresponding to that of FIGS. 3 and 4. To pass from one of the positions to the other (passage from "neutral") against the action of the spring 4, it is necessary to act on the engagement lever 6 either directly or indirect- is lying.
Lorsque la fixation est dans la position ouverte (figures 5 et 6) le levier d'enclenchement 6 sert de dis¬ positif d'enclenchement automatique ou step-in, l'utilisa¬ teur appuyant verticalement de haut en bas avec sa chaus¬ sure pour la mettre en position entre les mâchoires 2, pour faire pivoter ledit levier autour de l'axe 7 et ame¬ ner l'ensemble du système de bielettes dans la position fermée de service (figures 3 et 4), les griffes 3 des m⬠choires 2 enserrant alors entre elles la portion profilée ou empreinte C que présente la chaussure du surfeur.When the binding is in the open position (Figures 5 and 6) the engagement lever 6 serves as an automatic engagement device or step-in, the user pressing vertically up and down with his shoe to put it in position between the jaws 2, to rotate said lever around the axis 7 and ame¬ ner the entire system of rods in the closed service position (Figures 3 and 4), the claws 3 of the mâ ¬ choirs 2 then enclosing between them the profiled portion or imprint C that the shoe of the surfer has.
Pour ouvrir les mâchoires 2 et ainsi libérer la por¬ tion C de la chaussure, le surfeur devra alors actionner le levier à main 14 en le tirant vers le haut contre l'ac¬ tion du ressort 4 pour faire pivoter l'organe de manoeuvre 12 et faire ainsi remonter le levier d'enclenchement 6 dans sa position hors-service. Cette ouverture des m⬠choires peut bien entendu être provoquée en cas de chute, de choc ou de torsion, dès qu'un de ces événements pro¬ voque une tension sur les mâchoires 2 qui est supérieure à celle, préréglée, de l'organe élastique 4; le dispositif joue alors un rôle de sécurité, ce qui constitue un pro¬ grès indéniable sur les dispositifs de fixation actuelle¬ ment connus pour les surfs à neige.To open the jaws 2 and thus release the por¬ tion C of the shoe, the surfer will then have to operate the hand lever 14 by pulling it up against the action of the spring 4 to pivot the operating member. 12 and thus bring the engagement lever 6 back into its out-of-service position. This opening of the jaws can of course be caused in the event of a fall, shock or torsion, as soon as one of these events causes a tension on the jaws 2 which is greater than that, preset, of the organ elastic 4; the device then plays a safety role, which constitutes an undeniable progress on the fixing devices currently known for snowboarding.
La possiblité d'enclencher la fixation automatiquement (step-in) constitue ainsi un avantage pratique et un pro¬ grès important, les dispositifs de fixation pour surf à neige actuellement commercialisés nécessitant tous une ma¬ nipulation par le surfeur, par exemple pour fermer un étrier à l'avant de sa chaussure.
D'autre part, grâce à la réalisation du pivotement des mâchoires au moyen d'un bras articulé, les griffes 3 de ces mâchoires latérales 2 restent toujours en contact avec les empreintes correspondantes C de la semelle de la chaussure, même en présence souvent inévitable d'une épaisseur de neige, de glace, voire de terre ou de petits gravillons, entre cette semelle de chaussure et la plaque supérieure du dispositif de fixation, cette "épaisseur" non souhaitée étant en quelque sorte compensée par un jeu d'écartement un peu plus important (quelques mm) des m⬠choires 2 vers l'extérieur, rendu possible par l'articula¬ tion de celles-ci en 16 sur le bras de support 15, les té¬ tons d'articulation 16 étant eux-aussi écartés vers l'ex¬ térieur et la mâchoire 2 formant alors un angle légèrement obtu avec ledit bras 15.The possibility of engaging the binding automatically (step-in) thus constitutes a practical advantage and a significant step, the binding devices for snowboarding currently marketed all requiring manipulation by the surfer, for example to close a stirrup at the front of his shoe. On the other hand, thanks to the pivoting of the jaws by means of an articulated arm, the claws 3 of these lateral jaws 2 always remain in contact with the corresponding imprints C of the sole of the shoe, even in the often inevitable presence with a thickness of snow, ice, or even earth or small gravel, between this shoe sole and the upper plate of the fastening device, this unwanted "thickness" being in some way compensated for by a clearance clearance a slightly larger (a few mm) of the jaws 2 outwards, made possible by the articulation of these at 16 on the support arm 15, the hinge pins 16 also being separated towards the outside and the jaw 2 then forming a slightly obtuse angle with said arm 15.
Enfin, il convient de relever encore que le principe des mâchoires latérales apporte de nombreux avantages, dont les plus importants sont une sécurité de fonction accrue, la chaussure pouvant se dégager axialement vers l'avant et vers l'arrière sans obstacle, et le fait qu'il n'est plus nécessaire de procéder à un réglage de la fixa¬ tion lorsque le surf est utilisé par un autre utilisateur ayant des chaussures présentant une semelle de longueur différente. Cet avantage est particulièrement appréciable dans le cas des locations de planches à neige.Finally, it should also be noted that the principle of the side jaws provides numerous advantages, the most important of which are increased functional safety, the shoe being able to disengage axially forwards and backwards without obstacle, and that it is no longer necessary to adjust the fixa¬ tion when the surf is used by another user with shoes having a sole of different length. This advantage is particularly appreciable in the case of snowboard rentals.
Quant à la chaussure, il suffit que sa semelle pré¬ sente dans sa partie médiane une empreinte ou profil, ou des formations d'accrochage, correspondant à celles des mâchoires, soit venues de fabrication avec ladite semelle, soit rapportées sur celle-ci.
As for the shoe, it suffices for its sole to present in its middle part an imprint or profile, or attachment formations, corresponding to those of the jaws, which have come from manufacture with said sole, or be attached to it.
