Description

L'invention se rapporte au domaine des dispositifs de fixation d'un article chaussant sur un engin de glisse.The invention relates to the field of fastening devices of an article of footwear on a gliding machine.

L'invention sera plus particulièrement décrite dans son application à un dispositif de fixation d'une chaussure sur un engin de glisse (ski, surf des neiges, raquette à neige, patin à glace ou à roulettes, etc...), encore plus particulièrement dans son application à un dispositif de fixation de chaussure de ski de fond sur le ski correspondant.The invention will be more particularly described in its application to a device for attaching a shoe to a gliding device (skiing, snowboarding, snowshoeing, ice skating or roller skating, etc ...), even more particularly in its application to a ski boot binding device on the ski corresponding.

Dans tous les cas, une telle fixation comporte un mécanisme de verrouillage destiné à coopérer avec un organe de liaison de l'article chaussant, et un système d'ouverture manipulable par un utilisateur en vue de commander l'ouverture du mécanisme.In all cases, such a fastener comprises a locking mechanism intended to cooperate with a connecting member of the footwear, and an opening system manipulable by a user to control the opening of the mechanism.

Le mécanisme de verrouillage pourra être de types très variés, de même que l'organe de liaison correspondant de l'article chaussant.The locking mechanism may be of very varied types, as well as the corresponding connecting member of the footwear.

Dans de nombreux dispositifs de fixation, notamment de ski de fond, de randonnée ou de Telemark, l'organe de liaison de la chaussure est constitué d'un axe de liaison qui est destiné à être emprisonné dans une mâchoire. Un tel système est par exemple décrit dans les demandes de brevets FR-2.638.974 , FR-2.645.764 , FR-2.834.473 , FR-2.742.060 , FR-2.856.312 , FR-2.738.158 , EP-551.899 , EP-904.139 .In many fasteners, including cross-country skiing, hiking or Telemark, the binding member of the shoe consists of a connecting pin which is intended to be trapped in a jaw. Such a system is for example described in the patent applications FR-2638974 , FR-2645764 , FR-2834473 , FR-2742060 , FR-2856312 , FR-2738158 , EP-551 899 , EP-904 139 .

Dans d'autres dispositifs, l'organe de liaison de la chaussure est constitué de deux parties : soit deux axes de liaison parallèles ( EP-679.415 , FR-2.853.253 , FR-2.843.310 , WO-01/93963 ), soit une butée avant est un bec d'accrochage arrière ( FR-2.776.200 , FR-2.733.159 , EP-1.100.601 , DE-10.2004.018.296 ).In other devices, the binding member of the shoe consists of two parts: two parallel connecting axes ( EP-679 415 , FR-2853253 , FR-2843310 , WO-01/93963 ), a forward stop is a rear hooking spout ( FR-2776200 , FR-2733159 , EP-1100601 , DE-10.2004.018.296 ).

D'autres dispositifs sont décrits, par exemple dans le document EP-1.492.598 .Other devices are described, for example in the document EP-1492598 .

Tous ces dispositifs comportent un mécanisme de verrouillage, lequel est muni d'au moins une pièce mobile qui est destinée à coopérer avec l'organe de liaison de la chaussure. Cette pièce mobile est susceptible d'être déplacée entre une position active, dans laquelle elle assure le verrouillage entre l'organe de liaison et le dispositif de fixation, et une position de déverrouillage dans laquelle elle permet à l'organe de liaison, et donc aussi à la chaussure, d'être séparée du dispositif de fixation.All these devices comprise a locking mechanism, which is provided with at least one moving part which is intended to cooperate with the binding member of the boot. This movable piece can be moved between an active position, in which it ensures the locking between the connecting member and the fixing device, and an unlocking position in which it allows the connecting member, and therefore also to the shoe, to be separated from the fixing device.

Certains des dispositifs de fixation connus sont de type « step-in », (encore appelés semi-automatique ou à verrouillage automatique), dans la mesure où ils permettent que le verrouillage de l'organe de liaison sur le dispositif de fixation se fasse sans autre intervention de l'utilisateur que d'approcher l'organe de liaison du dispositif de fixation, et que d'exercer un certain effort pour provoquer le verrouillage. Dans la plupart des cas, c'est l'interaction de l'organe de liaison (ou d'une autre partie de la chaussure), avec un élément correspondant du dispositif de fixation qui provoque ce verrouillage automatique. Dans certains dispositifs, il est nécessaire d'amener la fixation dans un état ouvert (par une opération distincte, le plus souvent manuelle), l'interaction provoquant uniquement la fermeture du mécanisme de verrouillage (c.f. par exemple EP-1.100.601 ). Dans d'autres dispositifs, le mécanisme de verrouillage est dans un état fermé et l'interaction provoque l'ouverture du mécanisme qui se referme ensuite automatiquement, généralement sous l'effet d'un organe élastique (c.f. par exemple FR-2.645.764 ).Some of the known fastening devices are of the "step-in" type, (also called semi-automatic or automatically locking), insofar as they allow the locking of the connecting member on the fixing device to be done without other intervention of the user than to approach the connecting member of the fixing device, and that to exert a certain effort to cause locking. In most cases, it is the interaction of the connecting member (or another part of the shoe), with a corresponding element of the fixing device that causes this automatic locking. In some devices, it is necessary to bring the attachment into an open state (by a separate operation, usually manual), the interaction causing only the closing of the locking mechanism (cf, for example EP-1100601 ). In other devices, the mechanism of locking is in a closed state and the interaction causes the opening of the mechanism which then closes automatically, usually under the effect of an elastic member (cf, for example FR-2645764 ).

Dans d'autres dispositifs, l'utilisateur doit effectuer une opération spécifique d'ouverture et de fermeture à la fois pour le chaussage et pour le déchaussage.In other devices, the user must perform a specific operation of opening and closing for both the boot and the heaving.

Dans tous les cas cependant, les mécanismes de verrouillage comportent un système d'ouverture qui permet à l'utilisateur de commander le mécanisme vers son état ouvert (ou déverrouillé), ceci afin de permettre à l'utilisateur de libérer, à volonté et sans effort excessif, l'article chaussant du dispositif de fixation. Le système d'ouverture (généralement un levier, une tirette ou un bouton) doit ainsi être amené d'une première position à une seconde position pour provoquer le déverrouillage. L'utilisateur manipule ce système soit à la main, soit à l'aide d'un accessoire, par exemple un bâton de ski. Eventuellement, cette manipulation peut être une manipulation en deux temps, avec une pré-ouverture (consistant par exemple à provoquer le soulèvement d'un organe de préhension), puis une ouverture proprement dite (en manipulant l'organe de préhension précédemment mis à jour). Dans l'art antérieur, pour un système d'ouverture donné, la position d'ouverture est toujours la même et la direction de manipulation du système d'ouverture pour provoquer le déverrouillage est toujours la même.In all cases, however, the locking mechanisms include an opening system that allows the user to control the mechanism to its open (or unlocked) state, in order to allow the user to release, at will and without excessive stress, the footwear article of the fastening device. The opening system (usually a lever, a zipper or a button) must thus be brought from a first position to a second position to cause the unlocking. The user manipulates this system either by hand or with the aid of an accessory, for example a ski pole. Optionally, this manipulation can be a two-step manipulation, with a pre-opening (consisting for example of causing the lifting of a gripping member), then an actual opening (by manipulating the previously updated gripping member ). In the prior art, for a given opening system, the open position is always the same and the handling direction of the opening system to cause the unlocking is always the same.

Pour diverses raisons, tenant notamment à des considérations d'encombrement, de poids, de fiabilité et de nécessité de ne pas permettre une ouverture intempestive du dispositif de fixation, les systèmes d'ouverture ne sont pas toujours parfaitement ergonomiques. Ou alors, il sont relativement ergonomiques dans la plupart des situations, mais ne le sont pas assez dans d'autres situations dans lesquelles se trouve l'utilisateur.For various reasons, including considerations of space, weight, reliability and need not to allow inadvertent opening of the fastener, the opening systems are not always perfectly ergonomic. Or, they are relatively ergonomic in most situations, but not enough in other situations in which the user is.

Ainsi, dans le cas de fixation destinées à des enfants, on peut se trouver dans le cas où le système est assez facilement utilisable par l'enfant qui utilise le dispositif de fixation, mais peu facilement utilisable par une personne extérieure, par exemple un adulte qui souhaiterait aidé l'enfant à déverrouiller le système de fixation. Dans d'autres cas, il est possible que le système de fixation se révèle particulièrement complexe à manipuler par son utilisateur lorsque celui-ci a fait une chute et qu'il souhaite se dégager, alors qu'en utilisation normale, le système donne entièrement satisfaction.Thus, in the case of fixing intended for children, one can be in the case where the system is quite easily usable by the child who uses the fixing device, but can not easily be used by an outside person, for example an adult who would like to help the child unlock the fastening system. In other cases, it is possible that the fastening system is particularly complex to handle by the user when it has fallen and it wants to disengage, while in normal use, the system gives full satisfaction.

L'invention a pour but de proposer une nouvelle conception d'un dispositif de fixation dont la manipulation soit encore plus facile dans tous les cas de figures.The object of the invention is to propose a new design of a fixing device whose handling is even easier in all cases.

Dans ce but, l'invention propose un dispositif de fixation d'un article chaussant sur un article de sport, du type comprenant un mécanisme de verrouillage destiné à coopérer avec un organe de liaison de l'article chaussant, et du type comprenant un système d'ouverture manipulable par un utilisateur en vue de commander l'ouverture du mécanisme, caractérisé en ce que le système d'ouverture est susceptible d'être manipulé, directement ou indirectement, indifféremment selon au moins deux directions de manipulation distinctes pour commander l'ouverture du mécanisme. De ce fait, l'utilisateur ou une personne assistant l'utilisateur peut choisir le mode de commande le plus approprié pour lui.For this purpose, the invention proposes a device for fixing an article of footwear on a sports article, of the type comprising a locking mechanism intended to cooperate with a connecting member of the footwear, and of the type comprising a system aperture manipulable by a user for controlling the opening of the mechanism, characterized in that the opening system is capable of being manipulated, directly or indirectly, indifferently in at least two distinct directions of manipulation to control the opening opening of the mechanism. As a result, the user or a person assisting the user can choose the most appropriate control mode for him.

Selon une autre caractéristique de l'invention, le système d'ouverture comporte au moins deux organes de commande distincts qui sont manipulables chacun selon une des au moins deux directions de manipulation, privilégiant ainsi la possibilité d'adapter au mieux la géométrie de l'organe de commande à chacun des deux modes de manipulation. Dans ce cas, on peut prévoir que le système d'ouverture comporte un premier organe de commande qui, lorsqu'il est manipulé selon un première direction, commande directement l'ouverture du mécanisme de verrouillage, et un second organe de commande qui, lorsqu'il est manipulé selon une seconde direction de manipulation, commande l'ouverture du mécanisme par l'intermédiaire du premier organe de commandeAccording to another characteristic of the invention, the opening system comprises at least two distinct control members which can each be manipulated in one of at least two directions of manipulation, thus favoring the possibility of better adapting the geometry of the control member to each of the two modes of manipulation. In this case, it can be provided that the opening system comprises a first control member which, when manipulated in a first direction, directly controls the opening of the locking mechanism, and a second control member which, when it is manipulated in a second direction of manipulation, controls the opening of the mechanism via the first control member

En variante, le système d'ouverture peut comporter un organe de commande unique qui est manipulable selon les au moins deux direction de manipulation distinctes, privilégiant ainsi la simplicité, le faible coût de revient, et la fiabilité de fonctionnement du dispositif.Alternatively, the opening system may comprise a single control member which is manipulable in the at least two different handling direction, thus favoring simplicity, low cost, and reliable operation of the device.

L'invention sera ici décrite dans son application à des dispositifs de fixation destinés au ski de fond.The invention will be described here in its application to fixing devices for cross-country skiing.

Le premier exemple de réalisation d'un dispositif de fixation 10 illustré sur les figures 1 à 6 comporte une embase 12 qui est destinée à être fixée sur un article de sport 11, en l'occurrence donc un ski, mais qui pourrait aussi être directement intégré dans ce dernier. L'embase 12 pourrait aussi être réalisée en plusieurs parties, certaines ou non de ces parties étant éventuellement intégrées dans l'article de sport 11.The first embodiment of a fastening device 10 illustrated in FIGS. 1 to 6 comprises a base 12 which is intended to be fastened to a sports article 11, in the occurrence therefore a ski, but that could also be directly integrated in the latter. The base 12 could also be made of several parts, some or none of these parts being optionally integrated in the sport article 11.

Dans l'exemple illustré, le dispositif est destiné à assurer la fixation d'une chaussure 14 comportant des moyens de liaison en deux parties. La chaussure comporte deux barrettes de liaison 16, 18 qui sont agencées dans la semelle de la chaussure de manière à affleurer en dessous de celle-ci. Des barrettes de liaison 16, 18 de ce type sont décrites dans les demandes de brevet EP-A-913.102 et EP-A-913.103 auxquelles on se référera utilement pour plus de détails. Ainsi, il s'agit ici de deux barrettes cylindriques de révolution agencées en travers d'une rainure longitudinale aménagée dans la face inférieure de la semelle. La barrette avant 16 est par exemple située au voisinage de l'extrémité avant de la semelle et la barrette arrière 18 est décalée vers l'arrière d'une distance définie pour être agencée au niveau ou en avant d'une zone de la chaussure correspondant à la zone de flexion métatarso-phalangienne du pied de l'utilisateur. Cette disposition des zones de liaison est particulièrement appréciée en ski de fond car elle permet, avec une chaussure à semelle souple, de conserver une flexion de la chaussure correspondant à celle du pied. Cependant, l'invention pourrait être mise en oeuvre avec des organes de liaison présentant une autre géométrie ou une autre configuration, par exemple des barrettes de section non circulaire, des crochets, des becs ou des gorges d'accrochages formées directement dans le matériau de la semelle, etc...In the example shown, the device is intended to ensure the attachment of a shoe 14 having two-part connection means. The shoe comprises two connecting bars 16, 18 which are arranged in the sole of the shoe so as to be flush with it below. Link strips 16, 18 of this type are described in the patent applications EP-A-913102 and EP-A-913103 which will be usefully referred to for more details. Thus, it is here two cylindrical bars of revolution arranged across a longitudinal groove in the underside of the sole. The front bar 16 is for example located in the vicinity of the front end of the sole and the rear bar 18 is shifted rearwardly by a distance defined to be arranged at or in front of an area of the corresponding shoe to the metatarsophalangeal flexion zone of the user's foot. This arrangement of the binding areas is particularly appreciated in cross-country skiing because it allows, with a soft sole shoe, to maintain a flexion of the shoe corresponding to that of the foot. However, the invention could be implemented with connecting members having another geometry or another configuration, for example non-circular section bars, hooks, nozzles or grooves formed directly in the material of the sole, etc ...

La barrette avant 16 est destinée à coopérer, de façon connue en soi, avec un mécanisme de verrouillage 19 comportant une mâchoire mobile 20, en forme de crochet, et un bord transversal 22 de l'embase constituant une mâchoire fixe, pour le verrouillage rotatif de la chaussure sur l'article de sport. Une fois verrouillée dans le système de verrouillage, la barrette de liaison avant 16 peut pivoter librement à l'intérieur de la mâchoire, assurant donc une fixation articulée de l'extrémité avant de la chaussure.The front bar 16 is intended to cooperate, in a manner known per se, with a locking mechanism 19 comprising a mobile jaw 20, hook-shaped, and a transverse edge 22 of the base constituting a fixed jaw, for the rotary locking of the shoe on the article of sport. Once locked in the locking system, the front link 16 can pivot freely inside the jaw, thus providing an articulated attachment of the front end of the shoe.

La barrette arrière 18 est destinée à permettre l'accrochage d'un système de rappel élastique intégré à une arête de guidage 24 du dispositif. Un tel système de rappel élastique est par exemple décrit dans le document EP-768.103 au nom de la demanderesse. Il comporte ainsi une biellette 26 comportant une extrémité avant en forme de crochet 28 (destiné à venir s'accrocher sur la barrette arrière 18), et une extrémité arrière liée à l'embase 12 de manière à pouvoir coulisser longitudinalement et pivoter autour d'un axe transversal. Des moyens de rappel élastique (non visibles) tendent à ramener la biellette 26 dans la position de repos illustrée à la figure 1. De la sorte, lorsque le talon de la chaussure est soulevé, par pivotement de la chaussure autour de sa barrette avant 16, la biellette 26, accrochée sur la barrette arrière 18, peut suivre le déplacement vers le haut et vers l'avant de la barrette arrière 18, tout en exerçant sur celle-ci un effort de rappel qui tend à ramener la semelle de la chaussure vers la face supérieure du ski.The rear bar 18 is intended to allow the attachment of an elastic return system integrated in a guide edge 24 of the device. Such an elastic return system is for example described in the document EP-768 103 in the name of the plaintiff. It thus comprises a connecting rod 26 having a hook-shaped front end 28 (intended to hook onto the rear bar 18), and a rear end connected to the base 12 so as to be able to slide longitudinally and pivot around it. a transverse axis. Elastic return means (not visible) tend to return the rod 26 in the rest position shown in Figure 1. In this way, when the heel of the shoe is raised, by pivoting the shoe around its front bar 16 , the rod 26, hooked on the rear bar 18, can follow the upward and forward movement of the rear bar 18, while exerting on it a return force which tends to bring the sole of the shoe towards the upper face of the ski.

L'invention pourra aussi être mise en oeuvre pour des dispositifs comportant d'autres moyens de rappel élastique, par exemple comportant, à l'avant du dispositif de fixation, un tampon élastique contre lequel l'extrémité avant de la chaussure vient en appui lorsque son talon se soulève. Dans ce dernier cas, la chaussure peut ne comporter alors qu'une barrette de liaison.The invention may also be implemented for devices comprising other elastic return means, for example having, in front of the fixing device, a elastic buffer against which the front end of the shoe bears when its heel lifts. In the latter case, the shoe may then comprise only a link bar.

Les figures 2 à 6 illustrent plus particulièrement le mécanisme de verrouillage 19 de la barrette avant 16 de la chaussure. Pour la clarté des dessins, seule la barrette 16 de la chaussure est illustrée sur les figures 3, 5 et 6. Le principe de fonctionnement du mécanisme de verrouillage est ici parfaitement connu de l'art antérieur (comme par exemple dans les systèmes commercialisés par la demanderesse sous la dénomination commerciale « SNS Profil Auto »), et il n'est ici décrit qu'à titre indicatif, sachant que l'invention pourra être mise en oeuvre avec d'autres types de mécanismes de verrouillage.Figures 2 to 6 illustrate more particularly the locking mechanism 19 of the front bar 16 of the shoe. For clarity of the drawings, only the bar 16 of the shoe is illustrated in FIGS. 3, 5 and 6. The operating principle of the locking mechanism is here perfectly known from the prior art (as for example in the systems marketed by the applicant under the trade name "SNS Auto Profile"), and it is here described only as an indication, knowing that the invention can be implemented with other types of locking mechanisms.

Comme indiqué plus haut, le mécanisme 19 de verrouillage comporte pour l'essentiel un chariot 30 qui est mobile longitudinalement entre une position arrière de verrouillage (illustrée sur la figure 3), et une position avancée de déverrouillage (figures 5 et 6). Le chariot, par exemple réalisé en matière plastique moulée comporte un crochet supérieur 32 recourbé vers le haut et vers l'arrière. Le chariot peut comporter un renfort métallique 34 qui protège la face interne du crochet 32, laquelle est destinée à former un logement pour la barrette avant de la chaussure. En effet, lorsque le chariot 30 est en position reculée, le crochet 32 se trouve en regard du bord transversal 22 de l'embase 12 pour délimiter avec lui un logement, ouvert transversalement à ses deux extrémités, apte à recevoir la barrette 16. Lorsque la barrette 16 est reçue dans le logement et que le chariot est en position reculée, la barrette y est verrouillée et ne peut que pivoter autour de son axe. Au contraire, lorsque le chariot 30 est amené vers sa position avancée, le logement s'ouvre vers le haut, permettant la sortie la barrette hors du logement, ou son introduction dans le logement.As indicated above, the locking mechanism 19 essentially comprises a carriage 30 which is movable longitudinally between a rear locking position (illustrated in FIG. 3) and an advanced unlocking position (FIGS. 5 and 6). The carriage, for example made of molded plastic material has an upper hook 32 curved upwardly and rearwardly. The carriage may comprise a metal reinforcement 34 which protects the inner face of the hook 32, which is intended to form a housing for the front bar of the boot. Indeed, when the carriage 30 is in the retracted position, the hook 32 is facing the transverse edge 22 of the base 12 to delimit with it a housing, open transversely at both ends, adapted to receive the bar 16. When the bar 16 is received in the housing and the carriage is in the retracted position, the bar is locked there and can only pivot about its axis. On the contrary, when the carriage 30 is brought to its advanced position, the housing opens upwards, allowing the output of the bar out of the housing, or its introduction into the housing.

Les exemples de dispositifs de fixation 10 qui vont être décrits sont munis de mécanismes de verrouillage à engagement automatique. On peut voir en effet que le mécanisme de verrouillage comporte un ressort de compression 36 qui est en appui d'une part sur l'embase 12 et d'autre part sur le chariot 30 pour repousser ce dernier vers sa position arrière de verrouillage. Par ailleurs, on peut voir que le crochet 32 du chariot et le bord transversal 22 comportent des portions de rampes formant un profil en V. Un utilisateur peut ainsi engager la barrette avant 16 de sa chaussure en appui sur les rampes du crochet et du bord transversal de l'embase et, par simple appui vertical, provoquer, grâce aux rampes, l'avancée du crochet, à l'encontre de l'action du ressort 36. Une fois que le chariot 30 a avancé suffisamment, la barrette 16 peut s'engager à l'intérieur du logement, et le ressort 36 peut provoquer le retour du chariot 30 vers sa position de verrouillage dans laquelle le crochet 32 empêche que la barrette ne puisse sortir du logement. Un tel mécanisme de verrouillage à engagement automatique est avantageux car il permet le verrouillage de la chaussure sur le dispositif de fixation sans intervention particulière de l'utilisateur, contrairement à d'autres mécanismes ou le verrouillage de la chaussure nécessite une ou plusieurs opérations manuelles de l'utilisateur.Examples of fasteners 10 to be described are provided with self-locking mechanisms. It can be seen indeed that the locking mechanism comprises a compression spring 36 which is supported on the one hand on the base 12 and on the other hand on the carriage 30 to push the latter to its rear locking position. Furthermore, it can be seen that the hook 32 of the carriage and the transverse edge 22 comprise portions of ramps forming a V-shaped profile. A user can thus engage the front bar 16 of his shoe resting on the ramps of the hook and the edge. transverse of the base and, by simple vertical support, cause, thanks to the ramps, the advance of the hook, against the action of the spring 36. Once the carriage 30 has advanced sufficiently, the bar 16 can engage inside the housing, and the spring 36 can cause the carriage 30 to return to its locking position in which the hook 32 prevents the bar can go out of the housing. Such an automatic engagement locking mechanism is advantageous because it allows the locking of the boot on the fastening device without particular intervention of the user, unlike other mechanisms where the locking of the shoe requires one or more manual operations of the user.

De manière connue, le dispositif de fixation comporte un système d'ouverture manipulable par un utilisateur en vue de commander l'ouverture du mécanisme de verrouillage. Cependant, selon une caractéristique de l'invention, le système d'ouverture qui va être décrit est susceptible d'être manipulé, directement ou indirectement, indifféremment selon au moins deux directions de manipulation distinctes pour commander l'ouverture du mécanisme.In a known manner, the fixing device comprises a system that can be manipulated by a user in order to control the opening of the locking mechanism. However, according to one characteristic of the invention, the opening system that will be described is capable of being manipulated, directly or indirectly, indifferently in at least two distinct directions of manipulation to control the opening of the mechanism.

Dans les exemples décrits, l'ouverture du mécanisme de verrouillage nécessite de provoquer le déplacement du chariot 30 longitudinalement vers l'avant de sa position arrière de verrouillage à sa position avant ouverte. Bien entendu, avec d'autres mécanismes de verrouillage la commande d'ouverture pourrait nécessiter de commander d'autres mouvements de la pièce mobile (translation, rotation ou combinaison des deux), et/ou le même type de mouvement mais avec un sens différent.In the examples described, the opening of the locking mechanism requires causing the carriage 30 to move longitudinally forward of its locking rear position to its open forward position. Of course, with other locking mechanisms the opening control could require to control other movements of the moving part (translation, rotation or combination of both), and / or the same type of movement but with a different meaning .

Dans le premier exemple de réalisation de l'invention, le mécanisme d'ouverture est agencé à l'extrémité avant du dispositif de fixation, et il comporte deux organes de commande distincts qui sont manipulables chacun selon une des au moins deux directions de manipulation.In the first embodiment of the invention, the opening mechanism is arranged at the front end of the fixing device, and it comprises two separate control members which are each manipulable in one of at least two directions of manipulation.

Le premier organe de commande est un levier 38 qui est articulé par son extrémité avant d'articulation sur l'embase 12 autour d'un axe transversal A1. Le levier se prolonge par une palette de préhension 40 qui, dans sa position de repos illustrée aux figures 2 à 4, s'étend sensiblement horizontalement vers l'arrière au dessus de l'embase 12. Cette dernière est munie, sur ses faces latérales, d'évidements 42 qui permettent de rendre très accessible à la main de l'utilisateur les bords latéraux de la palette de préhension 40 du levier 38.The first control member is a lever 38 which is articulated by its hinge front end on the base 12 about a transverse axis A1. The lever is extended by a gripping pallet 40 which, in its rest position shown in Figures 2 to 4, extends substantially horizontally rearwardly above the base 12. The latter is provided on its side faces recesses 42 which make it possible to make the side edges of the gripping pallet 40 of the lever 38 very accessible to the user's hand.

Le second organe de commande est un tiroir 44 dont l'extrémité arrière est liée au chariot 30 par une tige d'articulation 46 d'axe transversal A2. La tige d'articulation 46 rend le tiroir 44 solidaire du chariot 30 en translation. L'extrémité avant du tiroir 44 est liée au levier 38 par une tige de liaison 48 d'axe transversal A3. La tige 48 traverse l'extrémité avant du tiroir 44 transversalement de part en part et présente deux portions d'extrémités transversales qui sont reçues dans des lumières 50 aménagées dans des flasques parallèles 52 du levier 38, lesquels flasques s'étendent verticalement et longitudinalement sous la palette de préhension 40. On remarque que l'avant du tiroir 44 est encadré transversalement par les deux flasques 52 et que les deux lumières 50 sont inclinées d'un angle d'environ 45 degrés vers l'avant et vers le bas. La tige de liaison 48 relie donc le tiroir 44 au levier 38 en permettant aux deux éléments d'avoir des déplacements relatifs en translation et en rotation.The second control member is a drawer 44 whose rear end is connected to the carriage 30 by a hinge pin 46 of transverse axis A2. The hinge pin 46 makes the slide 44 integral with the carriage 30 in translation. The front end of the slide 44 is connected to the lever 38 by a connecting rod 48 of transverse axis A3. The rod 48 passes through the front end of the slide 44 transversely from one end and has two transverse end portions which are received in slots 50 formed in parallel flanges 52 of the lever 38, which flanges extend vertically and longitudinally under the gripping pallet 40. Note that the front of the drawer 44 is transversely framed by the two flanges 52 and the two lights 50 are inclined at an angle of about 45 degrees forward and downward. The connecting rod 48 thus connects the slide 44 to the lever 38, allowing the two elements to have relative displacements in translation and in rotation.

Par ailleurs, on peut voir que le tiroir 44 comporte, dans sa partie avant, une tête 54 qui s'étend vers le haut de manière à dépasser vers l'extérieur au travers d'une ouverture 56 aménagée au centre de la palette de préhension 40 du levier 38.Moreover, it can be seen that the drawer 44 comprises, in its front part, a head 54 which extends upwardly so as to project outwardly through an opening 56 arranged in the center of the gripping pallet 40 of the lever 38.

Au repos, tel qu'illustré sur les figures 2 à 4, le levier 38 est en appui dams une position basse sur l'embase, tandis que le tiroir 44 est lui, sous l'effet du ressort 36 et via le chariot 30, dans une position reculée et haute dans laquelle la tige de liaison 48 qui est liée au tiroir 44 est reçue sensiblement à l'extrémité arrière haute des lumières obliques 50 du levier 38.At rest, as shown in Figures 2 to 4, the lever 38 is supported in a low position on the base, while the slide 44 is him, under the effect of the spring 36 and via the carriage 30, in a retracted and high position in which the connecting rod 48 which is connected to the slide 44 is received substantially at the high rear end of the oblique slots 50 of the lever 38.

Selon l'invention, l'utilisateur peut provoquer l'ouverture du mécanisme de verrouillage par deux actions distinctes.According to the invention, the user can cause the opening of the locking mechanism by two separate actions.

Premièrement, comme on peut le voir notamment à la figure 5, l'utilisateur peut exercer sur la tête 54 du tiroir 44 une pression sensiblement verticale du haut vers le bas, par exemple avec la main ou avec l'extrémité d'un bâton de ski (l'utilisation d'un bâton lui permettant d'ouvrir le dispositif sans avoir à se baisser). Sous l'effet de cette pression, la tige de liaison 48 qui est liée au tiroir 44 va coulisser dans les lumières 50 du levier 38. En effet, ce dernier reste alors immobile car il est en butée sur l'embase 12. En coulissant dans les lumières obliques 50, la tige de liaison 48 va provoquer une transformation de l'effort vertical exercé par l'utilisateur en un mouvement combiné du tiroir 44 (comme dans un système à came), ce mouvement étant la combinaison d'une translation longitudinale vers l'avant et d'une rotation autour de l'axe A2 (dans le sens anti-horaire sur las figures). Du fait que le tiroir 44 et le chariot 30 sont liés par une liaison pivot, la composante de translation longitudinale du mouvement du tiroir 44 est directement transmise au chariot 30, lequel est ainsi commandé vers sa position avant d'ouverture. Bien entendu, dès que l'utilisateur relâche son effort sur la tête 54 du tiroir 44, le ressort 36 ramène le tiroir 44 à sa position de repos, et, dans le même temps, le chariot 30 vers sa position arrière de verrouillage.First, as can be seen in particular in Figure 5, the user can exert on the head 54 of the drawer 44 a substantially vertical pressure from top to bottom, for example with the hand or with the end of a stick of ski (the use of a stick allowing him to open the device without having to bend down). Under the effect of this pressure, the connecting rod 48 which is connected to the slide 44 will slide in the slots 50 of the lever 38. Indeed, the latter then remains stationary because it is in abutment on the base 12. Sliding in the oblique lumens 50, the connecting rod 48 will cause a transformation of the vertical force exerted by the user in a combined movement of the slide 44 (as in a cam system), this movement being the combination of a translation longitudinal forward and rotation about the axis A2 (anti-clockwise in the figures). Because the slide 44 and the carriage 30 are connected by a pivot connection, the longitudinal translational component of the movement of the slide 44 is directly transmitted to the carriage 30, which is thus controlled to its position before opening. Of course, as soon as the user releases his effort on the head 54 of the drawer 44, the spring 36 returns the slide 44 to its rest position, and, at the same time, the carriage 30 to its locking rear position.

Deuxièmement, comme cela est illustré à la figure 6, l'utilisateur peut saisir la palette de préhension 40 du levier 38 et la soulever vers le haut, provoquant ainsi une rotation du levier autour de l'axe A1 (dans le sens anti-horaire sur les figures). Par ce mouvement de rotation, les lumières 52 des flasques 54 du levier 38 entraînent avec elles la tige de liaison 48 qui est solidaire du tiroir 44. Le tiroir 44 est ainsi entraîné vers l'avant, emmenant avec lui le chariot 30 vers sa position avant de déverrouillage. Comme dans le premier cas d'ouverture, dès que l'utilisateur relâche le levier 38, le ressort 36 ramène le chariot 30 et le tiroir 44 vers leur position de repos, et ce dernier ramène, par l'intermédiaire de la tige de liaison 48, le levier 38 vers sa position initiale.Secondly, as illustrated in FIG. 6, the user can grasp the handle pad 40 of the lever 38 and lift it upwards, thereby causing the lever to rotate about the axis A1 (counterclockwise in the figures). By this movement of rotation, the slots 52 of the flanges 54 of the lever 38 drive with them the connecting rod 48 which is integral with the slide 44. The slide 44 is thus driven forward, taking with it the carriage 30 to its position before unlocking. As in the first case of opening, as soon as the user releases the lever 38, the spring 36 returns the carriage 30 and the slide 44 to their rest position, and the latter brings back, via the connecting rod 48, the lever 38 to its initial position.

Conformément à l'invention, le système d'ouverture peut donc être manipulé de deux façons. La première façon est une pression exercée essentiellement vers le bas. La deuxième façon est une traction essentiellement vers le haut. A tout moment, l'utilisateur pourra donc choisir la façon de commander l'ouverture du mécanisme qui sera la plus pratique pour lui.According to the invention, the opening system can therefore be manipulated in two ways. The first way is a pressure exerted essentially down. The second way is essentially pulling upwards. At any time, the user can choose how to control the opening of the mechanism that will be most convenient for him.

Dans ce premier exemple de réalisation, le tiroir 44, lorsqu'il est manipulé vers le bas, commande directement l'ouverture du mécanisme de verrouillage, et le levier 38, lorsqu'il est manipulé vers le haut, commande l'ouverture du mécanisme par l'intermédiaire du tiroir 44, donc indirectement. On note par ailleurs que les deux organes de commande se déplacent selon des mouvements de natures différentes. On note aussi que le mécanisme de verrouillage et son système d'ouverture partagent un unique organe de rappel élastique, en l'occurrence le ressort 36.In this first exemplary embodiment, the slide 44, when it is handled downwards, directly controls the opening of the locking mechanism, and the lever 38, when it is handled upwards, controls the opening of the mechanism. through the drawer 44, so indirectly. Note also that the two control members move in different natures movements. It is also noted that the locking mechanism and its opening system share a single elastic return member, in this case the spring 36.

D'autres modes de réalisation de l'invention vont être décrits de manière très succincte ci-dessous, en référence aux dessins eux aussi très schématiques, destinés à illustrés différents systèmes possibles de commande d'ouverture. Ces exemples de réalisation sont décrits dans le cadre de dispositifs de fixation dont le mécanisme de verrouillage est réalisé sous la forme d'un chariot coulissant, comme celui qui vient d'être décrit un peu plus en détail. Outre que d'autres mécanismes sont envisageables, on se contentera ici d'une description schématique et sommaire, des éléments identiques ou similaires à ceux qui viennent d'être décrits pouvant ainsi être désignés par les mêmes chiffres de références. Notamment, pour simplifier la lecture, ces schémas de principe ne montrent pas de systèmes de rappel élastique du mécanisme de verrouillage et/ou des organes de commande de son ouverture. L'homme du métier pourra sans peine adapter des systèmes de rappel connus, par exemple des systèmes analogues au système à ressort 36 décrit ci-dessus.Other embodiments of the invention will be described very briefly below, with reference to the drawings, also very schematic, intended to illustrate different possible opening control systems. These exemplary embodiments are described in the context of fixing devices whose locking mechanism is designed as a sliding carriage, such as that which has just been described in a little more detail. In addition to other mechanisms are possible, it will be satisfied here with a schematic and summary description, elements identical or similar to those just described can thus be designated by the same reference numerals. In particular, to simplify the reading, these schematic diagrams do not show elastic return systems of the locking mechanism and / or the control members of its opening. Those skilled in the art can easily adapt known return systems, for example systems similar to the spring system 36 described above.

Le deuxième mode de réalisation de l'invention illustré aux figures 7 à 9 comporte lui aussi deux organes de commande d'ouverture distincts, mais, à la différence du premier mode de réalisation, ces deux organes sont animés, lorsqu'ils sont manipulés par l'utilisateur, d'un mouvement de même nature, en l'occurrence un mouvement de rotation.The second embodiment of the invention illustrated in FIGS. 7 to 9 also comprises two distinct opening control members, but, unlike the first embodiment, these two members are animated, when they are handled by the user, a movement of the same nature, in this case a rotational movement.

Ainsi, le chariot 30 du mécanisme de verrouillage comporte un prolongement vers l'avant qui se termine par un bec relevé 58 comportant une face d'appui 60 sensiblement verticale et tournée vers l'arrière.Thus, the carriage 30 of the locking mechanism comprises a forward extension which terminates in a raised beak 58 having a bearing face 60 substantially vertical and facing rearwardly.

Le système d'ouverture comporte un levier 38 qui est articulé sur l'embase 12 autour d'un axe transversal A4. Un basculeur 62 est articulé sur levier et/ou sur l'embase autour du même axe A4. Il pourrait éventuellement être articulé sur un axe décalé par rapport à l'axe A4.The opening system comprises a lever 38 which is articulated on the base 12 about a transverse axis A4. A rocker 62 is articulated on the lever and / or on the base around the same axis A4. It could possibly be articulated on an axis offset from the axis A4.

Le basculeur 62 comporte deux bras sensiblement perpendiculaires qui s'étendent sensiblement radialement depuis l'axe A4. Un bras supérieur 66 s'étend selon une direction sensiblement horizontale vers l'arrière et présente une face supérieure 68 sur laquelle un utilisateur peut venir exercer une pression verticale dirigée vers le bas, par exemple avec un bâton de ski. Un bras inférieur 70 s'étend sensiblement vers le bas et comporte un doigt de commande 72 qui est en appui vers l'avant contre la face d'appui 60 du bec relevé 58 du chariot 30. Lorsque l'utilisateur appuie vers le bas sur le bras supérieur 66, 68 (voir figure 8), il provoque une rotation du basculeur 62 autour de son axe A4 (dans le sens horaire sur les figures), le doigt 72 du basculeur 62 poussant alors le bec relevé 58 du chariot vers l'avant, jusqu'à sa position avant de déverrouillage.The rocker 62 comprises two substantially perpendicular arms which extend substantially radially from the axis A4. An upper arm 66 extends in a substantially horizontal direction towards the rear and has an upper face 68 on which a user can come to exert a vertical pressure directed downwards, for example with a ski pole. A lower arm 70 extends substantially downwardly and comprises a control finger 72 which bears forwards against the bearing face 60 of the raised beak 58 of the carriage 30. When the user presses down on the upper arm 66, 68 (see Figure 8), it causes a rotation of the rocker 62 about its axis A4 (clockwise in the figures), the finger 72 of the rocker 62 then pushing the raised beak 58 of the carriage to the 'before, to its position before unlocking.

On remarque par ailleurs qu'une butée 74 est prévue pour limiter la rotation du basculeur 62 dans l'une des deux directions. La butée est portée par le levier 38.Note also that a stop 74 is provided to limit the rotation of the rocker 62 in one of two directions. The stop is carried by the lever 38.

Lorsque l'utilisateur saisit l'extrémité avant du levier 38 et la soulève vers le haut (cf. figure 9), il provoque un rotation du levier 38 autour de l'axe A4, mais il provoque aussi, par l'intermédiaire de la butée 74, la rotation du basculeur 62, lequel, comme vu plus haut, provoque le déplacement vers l'avant du chariot 30. Dans l'exemple illustré, le levier 38 possède une tirette relevable 76 qui facilite la préhension et la manipulation du levier. Cependant, cette tirette 76 est optionnelle ; elle pourrait être remplacée par un cordon souple ou par une géométrie particulière du levier ou encore être omise, et elle n'est pas un organe de commande distinct du levier.When the user grasps the front end of the lever 38 and raises it upwards (see FIG. 9), it causes the lever 38 to rotate about the axis A4, but it also causes, via the stop 74, the rotation of the rocker 62, which, as seen above, causes the carriage 30 to move forwardly. In the illustrated example, the lever 38 has a liftable pull tab 76 which makes it easier to grip and handle the lever . However, this pull tab 76 is optional; it could be replaced by a flexible cord or by a particular geometry of the lever or be omitted, and it is not a control member separate from the lever.

Dans ce mode réalisation des figures 7 à 9, le système d'ouverture comporte deux organes de commande : le basculeur 62 qui commande directement l'ouverture du mécanisme de verrouillage, indépendamment de tout déplacement du second organe de commande, le levier 38 qui commande le mécanisme indirectement par l'intermédiaire du basculeur 62.In this embodiment of Figures 7 to 9, the opening system comprises two control members: the rocker 62 which directly controls the opening of the locking mechanism, independently of any movement of the second control member, the lever 38 which controls the mechanism indirectly via the rocker 62.

Un troisième mode de réalisation de l'invention est illustré aux figures 10 à 12, dans lequel le système d'ouverture du mécanisme de verrouillage ne comporte qu'un seul organe de commande. Comme cela ressort des figures, le système est identique au précédent, à la différence près que le levier et le basculeur sont confondus en une seule et même pièce : le basculeur 78 qui est articulé sur l'embase 12 autour de l'axe A4 et qui comporte d'une part une surface supérieure d'appui 68 agencée en arrière de l'axe A4, et d'autre part des moyens de préhension avant (en l'occurrence la tirette 76) agencés en avant de l'axe A4, de telle sorte que, pour provoquer le même mouvement de basculement du basculeur 78, l'utilisateur peut au choix appuyer vers le bas sur la surface arrière 68 ou tirer vers le haut les moyens de préhension avant 76. Dans les deux cas, le basculeur pivote autour de l'axe A4 et, par l'intermédiaire d'un doigt de commande 72, commande une translation vers l'avant du chariot 30.A third embodiment of the invention is illustrated in Figures 10 to 12, wherein the opening system of the locking mechanism comprises only one control member. As is apparent from the figures, the system is identical to the previous one, with the difference that the lever and the rocker are combined in one and the same piece: the rocker 78 which is articulated on the base 12 about the axis A4 and which comprises on the one hand an upper bearing surface 68 arranged behind the axis A4, and on the other hand front gripping means (in this case the pull tab 76) arranged in front of the axis A4, so that, to cause the same rocking movement of the rocker 78, the user can either press down on the rear surface 68 or pull up the front gripping means 76. In both cases, the rocker rotates about the axis A4 and, by means of a control finger 72, controls a translation towards the front of the carriage 30.

Les quatrième et cinquième modes de réalisation de l'invention décrits respectivement aux figures 13 à 15 et aux figures 16 à 18 comportent eux aussi un unique organe de commande de l'ouverture du mécanisme de verrouillage, lequel est, selon l'invention, susceptible d'être manipulé indifféremment selon deux directions de manipulation distinctes pour commander l'ouverture du mécanisme. Cependant, au contraire du mode de réalisation précédent, les deux directions de manipulation correspondent à des mouvements de l'organe de verrouillage qui ne sont pas de même nature.The fourth and fifth embodiments of the invention described respectively in FIGS. 13 to 15 and in FIGS. 16 to 18 also comprise a single device for controlling the opening of the locking mechanism, which, according to the invention, is capable of to be manipulated indifferently in two different directions of manipulation to control the opening of the mechanism. However, unlike the previous embodiment, the two manipulation directions correspond to movements of the locking member which are not of the same nature.

Ainsi, dans les deux cas, l'organe de commande est un levier 80 qui est lié à l'embase 12 par une tige de liaison 82. Cette tige de liaison 82 d'axe transversal A5 est solidaire de l'extrémité arrière du levier 80 et elle est reçue dans une lumière 84 de l'embase 12 (ou plusieurs lumières parallèles). La lumière 84 est sensiblement rectiligne et allongée selon la direction longitudinale de telle sorte que la liaison entre le levier 80 et l'embase 12 permet au levier de pivoter autour de l'axe A5 et de se translater longitudinalement. Par ailleurs, le levier 80 est en appui par son extrémité avant sur un pan incliné 86 de l'embase. Le pan incliné 86 est une face tournée vers le haut et vers l'avant, dont le profil est donc incliné vers le bas et vers l'avant. Le levier présente par exemple un pion ou un rouleau 88 qui est en contact avec le pan incliné 86. Par ailleurs, le levier 80 présente, à son extrémité avant, une surface supérieure d'appui 68, sur laquelle l'utilisateur peut exercer un effort sensiblement vertical vers le bas, et des bords latéraux 90 formant moyens de préhension pour permettre à un utilisateur de saisir l'extrémité avant du levier en vue de la soulever vers le haut. On remarque donc que le levier 80 est liée à l'embase 12 par une liaison à au moins deux degrés de liberté.Thus, in both cases, the control member is a lever 80 which is connected to the base 12 by a connecting rod 82. This link rod 82 of transverse axis A5 is integral with the rear end of the lever. 80 and it is received in a slot 84 of the base 12 (or several parallel lights). The lumen 84 is substantially rectilinear and elongate in the longitudinal direction so that the connection between the lever 80 and the base 12 allows the lever to pivot about the axis A5 and to translate longitudinally. Furthermore, the lever 80 is supported by its front end on an inclined portion 86 of the base. The inclined face 86 is a face facing upwards and forwards, whose profile is thus inclined downwards and forwards. The lever has, for example, a peg or a roll 88 which is in contact with the inclined face 86. Furthermore, the lever 80 has, at its front end, an upper bearing surface 68, on which the user can exert an substantially vertical downward force, and side edges 90 forming gripping means to allow a user to grasp the front end of the lever to lift upwardly. Note therefore that the lever 80 is connected to the base 12 by a connection to at least two degrees of freedom.

Dans le quatrième mode de réalisation illustré aux figures 13 à 15, le levier comporte, à son extrémité arrière, une came à excentrique 92 qui est agencée autour de l'axe A5 et qui est destinée à venir en appui contre la face arrière d'appui 60 du bec relevé 58 agencé à l'avant du chariot 30. Cette came 92 présente une excentricité telle que, lorsque l'utilisateur provoque le soulèvement du levier 80 en tirant son extrémité avant vers le haut, le levier 80 tournant alors autour de l'axe A5 de la tige de liaison 82, la surface de came 92 pousse le chariot 30 vers l'avant (cf. figure 15). On note que le levier 80 ne peut alors pas se translater vers l'arrière par rapport à l'embase 12 car la tige de liaison 82 est bloquée vers l'arrière contre l'extrémité arrière de la lumière 84. Le mouvement du levier est alors une pure rotation.In the fourth embodiment illustrated in FIGS. 13 to 15, the lever comprises, at its rear end, an eccentric cam 92 which is arranged around the axis A5 and which is intended to bear against the rear face of the cam. 60 of the raised beak 58 arranged at the front of the carriage 30. This cam 92 has an eccentricity such that, when the user causes the lifting of the lever 80 by pulling its front end upwards, the lever 80 then rotating around the axis A5 of the connecting rod 82, the cam surface 92 pushes the carriage 30 forwards (see Figure 15). Note that the lever 80 can not then translate backward relative to the base 12 because the connecting rod 82 is locked back against the rear end of the light 84. The movement of the lever is then a pure rotation.

Lorsque l'utilisateur appuie vers le bas sur la surface d'appui 68 du levier, le pion 88 tend à glisser sur le pan incliné 86 de telle sorte qu'il provoque (par un effet de système à came) une translation vers l'avant du levier 80. Cette translation est permise par le fait que la tige de liaison 82 peut alors se translater vers l'avant dans la lumière 84. La translation du levier 80 s'accompagne de fait d'une légère rotation du levier autour de l'axe A5 de la tige, mais c'est pour l'essentiel la translation globale du levier qui fait qu'il entraîne avec lui le chariot 30, par l'intermédiaire de la surface de came 92.When the user presses down on the bearing surface 68 of the lever, the pin 88 tends to slide on the inclined face 86 so that it causes (by a camming system effect) a translation towards the before the lever 80. This translation is enabled by the fact that the connecting rod 82 can then translate forward in the light 84. The translation of the lever 80 is accompanied by a slight rotation of the lever around A5 axis of the rod, but it is essentially the overall translation of the lever that it carries with it the carriage 30, through the cam surface 92.

Le cinquième mode de réalisation illustré aux figures 16 à 18 diffère du précédent uniquement par le fait que la tige 82 est au contact de la face arrière 60 du bec relevé 58 du chariot 30, et par le fait que le levier comporte une face arrière formant came 94 qui est destinée à venir en appui contre face de contact 96 correspondante de l'embase 12.The fifth embodiment illustrated in Figures 16 to 18 differs from the previous only in that the rod 82 is in contact with the rear face 60 of the raised beak 58 of the carriage 30, and in that the lever comprises a rear face forming cam 94 which is intended to bear against the corresponding contact face 96 of the base 12.

Lorsque l'utilisateur appuie sur la surface supérieure d'appui 68 du levier (cf.figure 17), le levier 80 se translate vers l'avant, comme pour le mode de réalisation précédent, et entraîne le chariot 30, cette fois par l'intermédiaire de la tige de liaison 82.When the user presses on the upper bearing surface 68 of the lever (see FIG. 17), the lever 80 translates forward, as in the previous embodiment, and drives the carriage 30, this time through the intermediate of the connecting rod 82.

Lorsque l'utilisateur soulève l'extrémité avant du levier 80 (cf. figure 18), la came 94 provoque, en fonction de l'angle de soulèvement, une translation horizontale vers l'avant de l'extrémité arrière du levier. Cette translation est alors directement répercutée au chariot 30 par la tige de liaison 82. Le mouvement du levier est ici un mouvement combiné de rotation et de translation.When the user raises the front end of the lever 80 (see Figure 18), the cam 94 causes, depending on the lifting angle, a horizontal translation forward of the rear end of the lever. This translation is then directly transmitted to the carriage 30 by the connecting rod 82. The movement of the lever here is a combined movement of rotation and translation.

Dans le sixième mode de réalisation de l'invention illustré sur les figures 19 à 21, le système d'ouverture comporte un unique organe de commande qui est un coulisseau 100 monté mobile en translation selon la direction verticale dans l'embase 12. Le coulisseau 100 possède une position centrale de verrouillage (figure 19) et deux positions basse et haute d'ouverture (figures 20 et 21). Le coulisseau 100 est lié au chariot 30 par un élément de liaison 102 qui est monté dans l'embase 12 de manière à pouvoir uniquement coulisser longitudinalement. L'extrémité avant de l'élément de liaison 102 comporte un pion transversal 104 qui est reçu dans une lumière 106 formée dans le coulisseau 100. La lumière 106 comporte deux branches : une branche supérieure 106a orientée vers le haut et vers l'avant, et une branche inférieure 106b orientée vers le bas et vers l'avant. En vue de côté, tel qu'illustré sur les figures, la lumière 106 présente donc un profil en V dont la pointe est dirigée longitudinalement vers l'arrière. Lorsque le coulisseau 100 est en position centrale, le pion 104 de l'élément de liaison est engagé dans la lumière 106 à l'intersection des deux branches, à la pointe du V.In the sixth embodiment of the invention illustrated in Figures 19 to 21, the opening system comprises a single control member which is a slide 100 mounted to be movable in translation in the vertical direction in the base 12. The slide 100 has a central locking position (Figure 19) and two low and high opening positions (Figures 20 and 21). The slider 100 is connected to the carriage 30 by a connecting element 102 which is mounted in the base 12 so as to be able to slide only longitudinally. The front end of the connecting element 102 comprises a transverse pin 104 which is received in a slot 106 formed in the slider 100. The light 106 has two branches: an upper branch 106a oriented upwards and forwards, and a lower branch 106b oriented downward and forward. In side view, as shown in the figures, the light 106 thus has a V-shaped profile whose tip is directed longitudinally backwards. When the slide 100 is in the central position, the pin 104 of the connecting element is engaged in the light 106 at the intersection of the two branches, at the tip of V.

Lorsque l'utilisateur enfonce le coulisseau 100 vers le bas, le pion 104, qui ne peut se déplacer verticalement, est forcé vers l'avant par la branche supérieure 106a de la lumière (figure 20), entraînant avec lui l'élément de liaison 102 et le chariot 30 vers l'avant.When the user pushes the slider 100 downwards, the pin 104, which can not move vertically, is forced forward by the upper branch 106a of the light (FIG. 20), driving with it the connecting element 102 and the carriage 30 forwards.

Lorsque l'utilisateur soulève le coulisseau 100 vers le haut, le pion 104 est forcé vers l'avant par la branche inférieure106b de la lumière (figure 21), entraînant avec lui l'élément de liaison 102 et le chariot 30.When the user raises the slider 100 upwards, the pin 104 is forced forward by the lower leg 106b of the light (FIG. 21), driving with it the connecting element 102 and the carriage 30.

Pour la manipulation du coulisseau 100 on a par exemple prévu qu'il comporte une face supérieure d'appui 68 et une tirette rabattable 76.For the handling of the slider 100, for example, it has been provided that it comprises an upper bearing face 68 and a folding pull-piece 76.

Chacun des modes de réalisation de l'invention permettent de concevoir un dispositif de fixation au maniement particulièrement ergonomique en toutes circonstances. Dans les modes de réalisations à deux organes de commande distincts, on privilégie la commodité d'emploi, en ayant la possibilité d'adapter au mieux la géométrie de l'organe de commande à chacun des deux modes de manipulation. Ainsi, suivant que l'organe de commande doit être par exemple tiré ou poussé, on peut mieux spécifier les surfaces de commandes pour par exemple faciliter la préhension manuelle ou l'appui avec un accessoire. On pourra aussi concevoir facilement des organes de commande présentant des effets de bras de levier adaptés à l'effort que l'utilisateur peut fournir selon la direction de manipulation correspondante, ceci en vue de commander avec une facilité équivalente le mécanisme de verrouillage selon les deux directions de manipulation. Dans les modes de réalisation à organe de commande unique, on privilégie la simplicité, le faible coût de revient, et la fiabilité de fonctionnement. Suivant la pratique à laquelle est destiné le dispositif de fixation, ou en fonction du type d'utilisateur visé, on peut ainsi choisir l'un ou l'autres des modes de réalisation, voire d'autres modes de réalisations dérivés de ceux illustrés ou décrits.Each of the embodiments of the invention makes it possible to design a fixing device that is particularly ergonomic in all circumstances. In embodiments with two separate control members, preference is given to the convenience of use, having the ability to better adapt the geometry of the control member to each of the two modes of manipulation. Thus, depending on whether the control member is to be pulled or pushed, for example, it is possible to better specify the control surfaces for, for example, facilitating manual gripping or support with an accessory. It is also easy to design control members having lever arm effects adapted to the effort that the user can provide according to the corresponding manipulation direction, in order to control with an equivalent facility the locking mechanism according to the two handling directions. In embodiments with a single controller, simplicity, low cost, and reliability of operation are preferred. Depending on the practice for which the fixing device is intended, or depending on the type of user targeted, one can thus choose one or the other of the embodiments, or even other embodiments derived from those illustrated or described.
