Description

TITRE : Canne télescopique notamment destinée à des personnes handicapées. TITLE: Telescopic rod especially intended for disabled people.
L'invention concerne une canne télescopique, munie d'un dispositif de préhension.The invention relates to a telescopic rod, provided with a gripping device.
Dans le domaine des outils de préhension utilisables, par exemple, par des personnes handicapées ou invalides, il est connu d'employer des cannes munies de pinces, lesquelles permettant à l'utilisateur de se saisir d'objets sans avoir à se baisser ou sans se déplacer.In the field of gripping tools that can be used, for example, by disabled or disabled persons, it is known to use canes equipped with tongs, which allow the user to grab objects without having to bend down or move.
Il est toutefois à remarquer qu'une telle destination n'est pas exclusive, et la canne de la présente invention pourra trouver de multiples applications domestiques, professionnelles, voire industrielles au, sens large.It should be noted, however, that such a destination is not exclusive, and the rod of the present invention will be able to find multiple domestic, professional and even industrial applications in the broad sense.
De même, le terme « canne » doit être compris au sens large comme tout moyen de manoeuvre pour un utilisateur dudit dispositif de préhension, tel que par exemple une tige ou un tube. Selon l'invention, ce moyen sera télescopique, comme on le verra dans la suite.Similarly, the term "rod" should be understood in the broad sense as any means of maneuver for a user of said gripping device, such as for example a rod or a tube. According to the invention, this means will be telescopic, as will be seen in the following.
Les cannes munies d'outils de préhension présentent à ce jour deux inconvénients importants :The rods equipped with gripping tools present to date two major disadvantages:
- la canne constituant le support de l'outil est fixe et rigide, et donc d'encombrement notable, ce qui présente un problème pour le rangement et le transport de l'instrument,the rod constituting the support of the tool is fixed and rigid, and therefore of significant size, which presents a problem for the storage and transport of the instrument,
- la canne munie de l'outil de préhension n'est utilisable que pour la fonction de préhension, ce qui pose aux utilisateurs le problème d'emporter avec eux un instrument uniquement dédié à la préhension des objets.- The cane equipped with the gripping tool can only be used for the gripping function, which poses the users the problem of carrying with them an instrument solely dedicated to gripping objects.
L'invention a donc pour objectif de résoudre ces principales difficultés en proposant une canne télescopique munie d'un outil de préhension à son extrémité qui soit notamment amovible. La présente invention concerne une canne télescopique, comprenant différents tronçons coaxiaux aptes à coulisser les uns dans les autres pour passer d'une position repliée à une position déployée, un mécanisme de verrouillage de la canne télescopique en position déployée, ladite canne présentant à son extrémité distale un dispositif de préhension actionnable par une seule main au moyen d'une manette installée sur une poignée, laquelle poignée étant placée à l'autre extrémité proximale de la canne, la manette et le dispositif de préhension étant reliés entre eux par une transmission, laquelle peut être actionnée quand la canne est en position déployée et verrouillée, pour la commande dudit dispositif de préhension.The invention therefore aims to solve these major difficulties by providing a telescopic rod with a gripping tool at its end which is particularly removable. The present invention relates to a telescopic rod, comprising different coaxial sections able to slide into each other to move from a folded position to an extended position, a locking mechanism of the telescopic rod in the deployed position, said rod having at its end distal a gripping device operable by a single hand by means of a lever installed on a handle, which handle is placed at the other proximal end of the rod, the handle and the gripping device being interconnected by a transmission, which can be actuated when the cane is in the deployed and locked position, for the control of said gripping device.
Selon l'invention, la transmission entre la manette et le dispositif de préhension est un système de tringlerie qui comporte au moins une tige de transmission rigide à l'intérieur de chaque tronçon constitutif de la canne télescopique, les tiges de transmission étant reliées entre elles, pour coopérer en butée lorsque la canne est en position déployée ? aptes à coulisser, à l'exception de celle installée dans le tronçon supérieur, pour se replier dans ledit tronçon supérieur lorsque la canne passe de la position déployée à la position repliée.According to the invention, the transmission between the handle and the gripping device is a linkage system which comprises at least one rigid transmission rod inside each constituent section of the telescopic rod, the transmission rods being interconnected. , to cooperate in abutment when the cane is in the deployed position? slidable, with the exception of that installed in the upper section, to fold into said upper section when the rod passes from the deployed position to the folded position.
Les avantages de la canne télescopique munie d'un dispositif de préhension selon l'invention sont multiples :The advantages of the telescopic rod provided with a gripping device according to the invention are multiple:
- la canne peut être repliée après utilisation et transportée sans difficulté en raison de son faible encombrement ;- The cane can be folded after use and transported without difficulty because of its small size;
- le dispositif de préhension, tout comme la poignée, peuvent notamment être démontés aisément pour être remplacés par un autre accessoire, par exemple le dispositif de préhension peut être remplacé par un pied simple ou un pied muni d'un amortisseur et la canne être ainsi utilisée pour aider à la marche une personne handicapée ou à mobilité réduite ; - l'aspect modulaire de l'instrument permet une personnalisation poussée des accessoires et une adaptation de la canne télescopique à de nombreux cas différents ;the gripping device, just like the handle, can in particular be dismounted easily to be replaced by another accessory, for example the gripping device can be replaced by a single foot or a foot provided with a shock absorber and the cane can be used to assist walking a disabled person or person with reduced mobility; - The modular aspect of the instrument allows for extensive customization of accessories and adaptation of the telescopic rod to many different cases;
- le système de tringlerie permet d'effectuer le repliement aisé de la canne en toute sécurité, sans risque de blocage des différents tronçons, pour constituer un ensemble replié ayant sensiblement la longueur du tronçon supérieur de l'instrument ;- The linkage system makes it easy to fold the rod safely, without risk of blocking the different sections, to form a folded assembly having substantially the length of the upper section of the instrument;
- les systèmes de couplage utilisés pour relier les différents éléments de la canne sont fiables et permettent un montage et un démontage rapide des accessoires installés à chaque extrémité de la canne ;- The coupling systems used to connect the different elements of the rod are reliable and allow quick assembly and disassembly of the accessories installed at each end of the cane;
- un mécanisme de verrouillage en fermeture du dispositif de préhension peut être avantageusement installé sur la poignée de manière à améliorer la fonctionnalité pratique de l'instrument.- A locking mechanism closing the gripping device can be advantageously installed on the handle so as to improve the practical functionality of the instrument.

La figure 22 représente en vue éclatée le tronçon inférieur de la canne, illustrée à la figure 19.22 shows an exploded view of the lower section of the cane, illustrated in Figure 19.
Tel que cela est représenté sur les figures 1 , 2, 5 et 6, la canne télescopique selon l'invention comporte plusieurs tronçons 1 à 3 formés de tubes coaxiaux emboîtables les uns dans les autres par coulissement lorsque le mécanisme de déverrouillage est actionné.As shown in Figures 1, 2, 5 and 6, the telescopic rod according to the invention comprises a plurality of sections 1 to 3 formed of coaxial tubes slidable in one another by sliding when the unlocking mechanism is actuated.
Au minimum, la canne télescopique comporte deux tronçons.At a minimum, the telescopic rod has two sections.
Selon un exemple de réalisation avantageux, la canne télescopique comporte un tronçon supérieur 1 , au moins un tronçon intermédiaire 2 et un tronçon inférieur 3 sur lequel est fixé le dispositif de préhension 8.According to an advantageous exemplary embodiment, the telescopic rod comprises an upper section 1, at least one intermediate section 2 and a lower section 3 on which the gripping device 8 is fixed.
Sur les figures, il est représenté deux tronçons intermédiaires identiques à la variation de diamètre près des différents tubes constitutifs.In the figures, there are shown two intermediate sections identical to the diameter variation near the various constituent tubes.
Le tronçon supérieur 1 est destiné à être connecté par son extrémité proximale 4 à une poignée 6, laquelle poignée 6 pouvant être configurée de différentes manières sans sortir du cadre de l'invention.The upper section 1 is intended to be connected by its proximal end 4 to a handle 6, which handle 6 can be configured in different ways without departing from the scope of the invention.
Le tronçon inférieur 3 est destiné à être connecté par son extrémité distale inférieure 5 au dispositif de préhension 8. Dans la configuration repliée de la canne, représentée sur la figure 2, on peut constater que l'emboîtement par coulissement des tubes qui constituent les différents tronçons 1 , 2, 3 conduit à une dimension de canne réduite à quasiment la longueur du tronçon 1.The lower section 3 is intended to be connected by its lower distal end 5 to the gripping device 8. In the folded configuration of the rod, shown in FIG. 2, it can be seen that the sliding engagement of the tubes constituting the different sections 1, 2, 3 leads to a rod dimension reduced to almost the length of the section 1.
La figure 3 illustre une poignée 6 pouvant être installée sur la canne télescopique, laquelle comporte une manette 7.FIG. 3 illustrates a handle 6 that can be installed on the telescopic rod, which comprises a handle 7.
La figure 4 illustre un dispositif de préhension 8 à deux mors 11 pouvant être installé sur le tronçon inférieur 3, à l'extrémité distale de la canne.FIG. 4 illustrates a gripping device 8 with two jaws 11 that can be installed on the lower section 3, at the distal end of the cane.
Selon l'invention, la manette 7 et le dispositif de préhension 8 sont reliés entre eux par un système de tringlerie, lequel peut être actionné quand la canne est en position déployée et verrouillée, pour la commande dudit dispositif de préhension.According to the invention, the handle 7 and the gripping device 8 are interconnected by a linkage system, which can be actuated when the rod is in the deployed and locked position, for the control of said gripping device.
Lorsque la canne est dans la position d'extension maximale, illustrée sur les figures 1 , 5 et 6, l'action de la manette est efficace sur le dispositif de préhension 8.When the rod is in the maximum extension position, illustrated in Figures 1, 5 and 6, the action of the joystick is effective on the gripping device 8.
A ce sujet, on notera que, selon l'invention, la fonction de verrouillage/déverrouillage du déploiement/repliement et la fonction de commande dudit dispositif de préhension sont dissociées et séparées.In this regard, it will be noted that, according to the invention, the function of locking / unlocking deployment / folding and the control function of said gripping device are separated and separated.
Lorsque la manette 7 est pressée contre la poignée 6, par la fermeture de la main de l'utilisateur qui serre la poignée, alors que la canne est en position déployée et verrouillée en position déployée, ladite manette se déplace et actionne le dispositif de préhension 8 en fermeture. Lorsque la pression sur la manette 7 se relâche, la manette est repoussée sous l'action de ressorts 14, représentés sur les figures 9 et 10, ce qui a pour effet d'ouvrir le dispositif de préhension 8.When the handle 7 is pressed against the handle 6, by closing the hand of the user who closes the handle, while the rod is in the deployed position and locked in the deployed position, said handle moves and actuates the gripping device 8 in closing. When the pressure on the handle 7 is released, the handle is pushed back under the action of springs 14, shown in FIGS. 9 and 10, which has the effect of opening the gripping device 8.
Les figures 5 et 6 montrent la canne télescopique en position déployée, ainsi que ledit dispositif de tringlerie de l'invention relié à la manette 7 par un côté, et relié au dispositif de préhension 8 par l'autre côté. Selon l'invention, le système de tringlerie comporte au moins une tige de transmission 9 rigide à l'intérieur de chaque tronçon 1 , 2, 3 constitutif de la canne télescopique.Figures 5 and 6 show the telescopic rod in the deployed position, and said linkage device of the invention connected to the handle 7 by one side, and connected to the gripping device 8 by the other side. According to the invention, the linkage system comprises at least one rigid transmission rod 9 inside each section 1, 2, 3 constituting the telescopic rod.
Sur les différentes figures et pour l'exemple décrit, chaque tronçon 1, 2 ou 3 comporte une seule tige de transmission 9.In the various figures and for the example described, each section 1, 2 or 3 comprises a single transmission rod 9.
Toutefois, il peut être envisagé deux tiges ou plus par tronçon de la canne sans sortir du cadre de l'invention.However, it can be envisaged two rods or more per section of the cane without departing from the scope of the invention.
Avantageusement, les tiges de transmission 9 sont reliées entre elles et sont aptes à coulisser, parallèlement au déploiement/reploiement de la canne, à l'exception de celle installée dans le tronçon supérieur 1 , pour se replier dans ledit tronçon supérieur 1 lorsque la canne passe de la position déployée à la position repliée.Advantageously, the transmission rods 9 are interconnected and are able to slide, parallel to the deployment / retreat of the rod, with the exception of that installed in the upper section 1, to fold in said upper section 1 when the cane moves from the deployed position to the folded position.
Dans la représentation de l'invention illustrée par les différentes figures, les tiges de transmission 9 coulissent les unes sur les autres en parallèle pour former après repliement de la canne un ensemble compact dans lequel les tiges sont superposées dans le tronçon 1.In the representation of the invention illustrated by the various figures, the transmission rods 9 slide over each other in parallel to form after folding of the cane a compact assembly in which the rods are superimposed in the section 1.
Sur les figures 5 et 6, les tiges de transmission 9 sont plates, ou de section ronde, et coulissent dans des guides 10 portés par les extrémités inférieures des tiges de transmission, dont la conformation, notamment en forme d'anneau, correspond au profil desdites tiges 9.In FIGS. 5 and 6, the transmission rods 9 are flat, or of round section, and slide in guides 10 carried by the lower ends of the transmission rods, the conformation of which, in particular in the form of a ring, corresponds to the profile. said rods 9.
Plus précisément, chaque tige 9 présente un guide 10 à l'une de ses extrémités apte à coopérer avec une autre tige 9 consécutive du tronçon suivant. Notamment, l'extrémité de ladite tige est repliée pour former ledit guide. Selon un autre mode de réalisation, les tiges de transmission 9 sont de section ronde.More specifically, each rod 9 has a guide 10 at one of its ends adapted to cooperate with another rod 9 consecutive next section. In particular, the end of said rod is folded to form said guide. According to another embodiment, the transmission rods 9 are of round section.
Avantageusement, et tel que cela est représenté sur les différentes figures, les tiges de transmission 9 ont sensiblement la longueur des tronçons coaxiaux. Par ailleurs, lorsque les tronçons 1 , 2, 3 sont déployés, lesdites extrémités inférieures équipées desdits guides 10 sont prévues pour coopérer avec l'extrémité distale d'une tige 9 contigϋe afin de venir en butée respectivement et ainsi permettre de véhiculer l'effort de traction engendré au niveau de la poignée 6. Dans l'autre sens, le coulissant est autoriser pour replier la canne.Advantageously, and as shown in the various figures, the transmission rods 9 have substantially the length of the coaxial sections. Moreover, when the sections 1, 2, 3 are deployed, said lower ends equipped with said guides 10 are provided to cooperate with the distal end of a contiguous rod 9 in order to abut respectively and thus allow the force to be conveyed Traction generated at the handle 6. In the other direction, the sliding is allowed to fold the cane.
La tige de transmission du tronçon supérieur 1 de la canne est reliée par un système de couplage avec le mécanisme d'actionnement de la manette 7.The transmission rod of the upper section 1 of the rod is connected by a coupling system with the actuating mechanism of the lever 7.
Les vues en coupe des figures 5 et 6 montrent que lorsque la manette 7 est pressée, les différentes tiges de transmission 9 se déplacent dans le sens de la manette, ce qui a pour effet de déplacer les mors 11 dans le sens de la fermeture.The sectional views of Figures 5 and 6 show that when the handle 7 is pressed, the various transmission rods 9 move in the direction of the handle, which has the effect of moving the jaws 11 in the direction of closure.
Avantageusement, selon l'invention la manette 7 comporte un moyen complémentaire de verrouillage 12 permettant de maintenir le dispositif de préhension dans la position de serrage, pour le blocage en position verrouillage du dispositif de préhension.Advantageously, according to the invention the handle 7 comprises a complementary locking means 12 for holding the gripping device in the clamping position, for locking in the locking position of the gripping device.
La poignée 6 et ses organes constitutifs sont représentés sur les figures 7 à 10 plus précisément. Les figures 9 et 10 montrent notamment le fonctionnement du moyen complémentaire de verrouillage 12 sous l'action de la gâchette 13.The handle 6 and its constituent members are shown in FIGS. 7 to 10 more precisely. FIGS. 9 and 10 show in particular the operation of the complementary locking means 12 under the action of the trigger 13.
La gâchette 13 est en fait une pièce articulée en rotation qui permet, lorsqu'elle est actionnée, d'empêcher le retour de la manette 7 vers sa position de repos, laquelle position de repos étant usuellement atteinte sous l'action des ressorts 14 lorsque l'utilisateur relâche la pression sur la manette 7.The trigger 13 is in fact a rotatably articulated piece which, when it is actuated, prevents the return of the handle 7 towards its rest position, which rest position is usually reached under the action of the springs 14 when the user releases the pressure on the handle 7.
Les figures 7 et 8 illustrent l'emboîtement de la poignée 6 avec le tronçon supérieur 1 et le mécanisme de couplage pour la transmission du mouvement de translation de la manette vers la tringlerie. Afin que la poignée 6 soit solidement maintenue avec le tronçon supérieur 1 , il est prévu que les éléments soient couplés par exemple par un dispositif à baïonnette et verrouillés en fermeture avec un ergot 15.Figures 7 and 8 illustrate the interlocking of the handle 6 with the upper section 1 and the coupling mechanism for transmitting the translational movement of the lever to the linkage. So that the handle 6 is firmly held with the upper section 1, it is expected that the elements are coupled for example by a bayonet device and locked in closure with a lug 15.
Pour effectuer le raccordement, les deux éléments sont d'abord emboîtés l'un dans l'autre et une rotation relative d'un élément par rapport à l'autre autour de l'axe de la canne est ensuite effectuée pour solidariser les parties.To make the connection, the two elements are first nested one inside the other and a relative rotation of one element relative to the other around the axis of the rod is then performed to secure the parts.
Selon l'invention, la tige de transmission du tronçon inférieur 3 de la canne comporte un système de couplage avec le dispositif de préhension 8.According to the invention, the transmission rod of the lower section 3 of the rod comprises a coupling system with the gripping device 8.
Un mécanisme de raccordement voisin du dispositif de connexion de la poignée est, par exemple, prévu pour maintenir fermement le dispositif de préhension 8 avec le tronçon inférieur 3.An adjacent connection mechanism of the connection device of the handle is, for example, provided for firmly holding the gripping device 8 with the lower section 3.
Avantageusement, selon l'invention, le dispositif de préhension 8 est une pince à deux ou à trois mors et les couplages entre la poignée 6 et le tronçon supérieur 1 et entre le tronçon inférieur 3 et le dispositif de préhension 8 emploient des coupleurs à baïonnettes.Advantageously, according to the invention, the gripping device 8 is a clamp with two or three jaws and the couplings between the handle 6 and the upper section 1 and between the lower section 3 and the gripping device 8 employ bayonet couplers .
Le dispositif de préhension est représenté plus en détail sur la figure 11.The gripping device is shown in more detail in FIG.
Cette figure montre le dispositif de couplage à baïonnette 16, un manchon de verrouillage 17 du dispositif de couplage, et les mors 11 aptes à se déplacer parallèlement sous l'action de la fourche 18. Ladite fourche transforme le mouvement de translation de la tringlerie 9, 10 qui s'opère dans l'axe de la canne en mouvement de traction perpendiculaire pour la fermeture et l'ouverture des mors 11.This figure shows the bayonet coupling device 16, a locking sleeve 17 of the coupling device, and the jaws 11 able to move parallel under the action of the fork 18. Said fork transforms the translational movement of the linkage 9 10 which operates in the axis of the rod in perpendicular traction movement for the closure and opening of the jaws 11.
Lorsque la manette 7 est actionnée, les tiges de transmission 9, 10 se déplacent en translation dans la direction de la poignée 6. Comme cela est représenté lors du passage de la figure 5 à la figure 6, la mise en traction de la fourche se traduit par un déplacement en fermeture des mors. Lorsque la pression sur la manette 7 est relâchée, les ressorts de rappel 14 ramènent la manette 7 dans sa position de repos et le système de tringlerie 9, 10 dans sa position initiale, soit donc avec les mors 11 en position d'ouverture.When the lever 7 is actuated, the transmission rods 9, 10 move in translation in the direction of the handle 6. As shown during the passage from Figure 5 to Figure 6, the traction of the fork is translated by a displacement in closing of the jaws. When the pressure on the handle 7 is released, the return springs 14 bring the 7 lever in its rest position and the linkage system 9, 10 in its initial position, so with the jaws 11 in the open position.
Selon un exemple avantageux de réalisation de l'invention, la canne télescopique avec sa poignée et sa pince a une longueur de 95 cm, la course en translation des mors est de l'ordre de 30 mm, la grande dimension du dispositif de préhension est sensiblement de 20 cm.According to an advantageous embodiment of the invention, the telescopic rod with its handle and its clamp has a length of 95 cm, the travel in translation of the jaws is of the order of 30 mm, the large dimension of the gripping device is substantially 20 cm.
La partie correspondant aux quatre tronçons coaxiaux mesure 65 cm en position déployée et 25 cm en position repliée.The part corresponding to the four coaxial sections measures 65 cm in the extended position and 25 cm in the folded position.
Plusieurs variantes de la canne télescopique munie d'une pince de préhension sont envisageables, notamment le mécanisme de couplage non définitif permet de placer différents organes de préhension et même éventuellement d'autres accessoires, un pied par exemple, sans sortir du cadre de l'invention. Ce qui permet de réaliser une canne multifonction.Several variants of the telescopic rod provided with a gripper can be envisaged, in particular the non-definitive coupling mechanism makes it possible to place different gripping members and even possibly other accessories, such as a foot, without departing from the scope of the drawing. invention. This allows for a multifunctional rod.
De la même manière, différentes poignées peuvent être agencées, comportant des formes variées et disposant de diverses fonctionnalités, par exemple notamment avec un dispositif de verrouillage du dispositif de préhension pouvant être conçu de plusieurs manières différentes sans sortir du cadre de l'invention.In the same way, different handles can be arranged, having various shapes and having various functionalities, for example with a locking device of the gripping device that can be designed in several different ways without departing from the scope of the invention.
La tringlerie interne à la canne peut être composée de tiges rigides de transmission plates ou rondes de différentes dimensions et les éléments peuvent coulisser pour leur repliement selon divers modes sans sortir du cadre de l'invention.The linkage internal to the rod can be composed of rigid flat or round transmission rods of different dimensions and the elements can slide for their folding in various modes without departing from the scope of the invention.
De même les guides permettant le maintien des tiges de transmission lors du repliement de la canne peuvent être prévus de différentes manières, c'est-à- dire par exemple sur les tiges elles-mêmes ou avec des inserts de guidage positionnés dans les tronçons coaxiaux constitutifs de la canne.Similarly, the guides for holding the transmission rods during the folding of the rod can be provided in different ways, that is to say for example on the rods themselves or with guiding inserts positioned in the coaxial sections constituent parts of the cane.
Divers mécanismes peuvent être envisagés pour le verrouillage de la canne télescopique en position déployée sans sortir du cadre de l'invention, par exemple au moyen d'ergots ou d'un dispositif à vis, lequel verrouillage ayant pour effet de permettre l'actionnement du dispositif de préhension.Various mechanisms can be envisaged for locking the telescopic rod in the deployed position without departing from the scope of the invention, by example by means of lugs or a screw device, which locking having the effect of allowing the actuation of the gripping device.
En particulier, le mécanisme de reploiement et de déploiement de la canne peut comporter au moins des ergots 25 de verrouillage pressés radialement vers l'extérieur par des ressorts, placés sur les différents tronçons coaxiaux 1 , 2, 3.In particular, the mechanism for folding and deploying the cane may comprise at least locking lugs 25 pressed radially outwards by springs, placed on the different coaxial sections 1, 2, 3.
En position verrouillée, tel qu'illustré aux figures 1 , 5 et 6, lesdits ergots 25 passent au travers d'orifices aménagés dans les tubes respectifs, constituant lesdits tronçons contigus, l'ergot 25 porté par un tronçon déterminé passant au travers de l'orifice d'un tronçon adjacent de manière à verrouiller les tronçons entre eux en translation et en rotation.In the locked position, as illustrated in FIGS. 1, 5 and 6, said lugs 25 pass through orifices provided in the respective tubes, constituting said contiguous sections, the lug 25 carried by a determined section passing through the orifice of an adjacent section so as to lock the sections together in translation and in rotation.
A contrario, lorsque ledit ergot 25 est repoussé vers l'intérieur dans son logement, et lorsque le ressort est comprimé, le tube porteur de l'ergot peut coulisser dans le tube adjacent en vue du repliement de la canne, tel qu'illustré à la figure 2.Conversely, when said lug 25 is pushed inwards in its housing, and when the spring is compressed, the lug carrier tube can slide in the adjacent tube for the folding of the rod, as illustrated in FIG. Figure 2.
Selon un mode de réalisation, le mécanisme de repliement ou de déploiement est aisément manipulable de la part de l'utilisateur, notamment voire avec une seule main, et sans effort important.According to one embodiment, the folding or deployment mechanism is easily manipulated by the user, especially with one hand, and without significant effort.
Une fois que le mécanisme de déverrouillage est actionné manuellement sur le tronçon supérieur, une pression peu importante dans l'axe de la canne permet de replier celle-ci par un déverrouillage en cascade de chaque tronçon.Once the unlocking mechanism is manually actuated on the upper section, a small pressure in the axis of the rod can fold it by unlocking a cascade of each section.
La pression appliquée est faible et réalisable avec une seule main au niveau de la tête de la canne lorsque la canne est appuyée sur un support quelconque à son extrémité inférieure, celle correspondant au pied de la canne.The applied pressure is low and achievable with one hand at the head of the cane when the cane is supported on any support at its lower end, that corresponding to the foot of the cane.
Selon un mode de réalisation, le mécanisme de repliement ou de déploiement comporte des bagues 27, ainsi que les ergots 25 de verrouillage actionnés avec des ressorts 26, placés en coopération sur les différents tronçons 1 , 2, 3,coaxiaux.According to one embodiment, the folding or deployment mechanism comprises rings 27, as well as the locking pins 25. actuated with springs 26, placed in cooperation on the different sections 1, 2, 3, coaxial.
Plus précisément, l'extrémité distale de chaque tronçon supérieur 1 et intermédiaire 2 comporte une bague 27 et l'extrémité proximale de chaque tronçon intermédiaire 2 et inférieur 3 comporte un ergot 25, les bagues 27 et ergots 25 étant aptes à coopérer pour assurer le déverrouillage desdits tronçons 1 , 2, 3.More specifically, the distal end of each upper section 1 and intermediate 2 comprises a ring 27 and the proximal end of each intermediate section 2 and lower 3 has a lug 25, the rings 27 and lugs 25 being adapted to cooperate to ensure the unlocking said sections 1, 2, 3.
Les figures 14 à 22 montrent les ergots 25 maintenus en pression vers l'extérieur par des ressorts 26, montés radialement par rapport aux tronçons. En position verrouillée, les ergots 25 passent au travers d'orifices aménagés dans les tubes respectifs constituant lesdits tronçons contigus, l'ergot porté par un tronçon déterminé passant au travers de l'orifice d'un tronçon adjacent de manière à verrouiller les tronçons entre eux, en translation et en rotation.Figures 14 to 22 show the lugs 25 held in pressure outwardly by springs 26, mounted radially relative to the sections. In the locked position, the lugs 25 pass through orifices arranged in the respective tubes constituting said contiguous sections, the lug carried by a determined section passing through the orifice of an adjacent section so as to lock the sections between them, in translation and in rotation.
A l'exception du tronçon supérieur 1 , tous les tubes portent un ergot 25 destiné à se verrouiller dans l'orifice d'un tube adjacent. De même, à l'exception du tronçon inférieur 3, tous les tubes comportent une bague 27 pour agir sur ledit ergot 25 correspondant.With the exception of the upper section 1, all the tubes have a lug 25 for locking in the orifice of an adjacent tube. Likewise, with the exception of the lower section 3, all the tubes comprise a ring 27 to act on said corresponding lug 25.
Lorsque l'ergot 25 est repoussé, vers l'intérieur, dans son logement et que le ressort 26 est comprimé, le tube porteur de l'ergot est apte à coulisser dans le tube adjacent. Cette configuration correspond à la position de repliement de la canne telle qu'elle se présente sur les figures 13 et 15.When the lug 25 is pushed inwards into its housing and the spring 26 is compressed, the lug carrier tube is slidable in the adjacent tube. This configuration corresponds to the folding position of the cane as it appears in FIGS. 13 and 15.
Dans la position repliée de la figure 15, les tubes coaxiaux sont emboîtés les uns dans les autres. Les ergots 25 se trouvent à l'intérieur de chaque tube et à proximité de la partie supérieure de la canne télescopique.In the folded position of Figure 15, the coaxial tubes are nested within each other. The lugs 25 are located inside each tube and near the upper part of the telescopic rod.
Selon l'invention, la conformation des bagues 27 assure, lors du repliement, le déverrouillage automatique en cascade des ergots 25 portés par les différents tronçons lorsque le tronçon supérieur 1 est déverrouillé et qu'une pression est appliquée entre les deux extrémités de la canne. La conformation des bagues 27 comporte, comme le montre notamment la figure 17, un chanfrein interne qui oblige automatiquement les ergots 25 à s'effacer dans les tubes lors du déplacement en translation desdites bagues et des tronçons les uns par rapport aux autres dans le sens de repliement de la canne.According to the invention, the conformation of the rings 27 ensures, during the folding, the automatic unlocking in cascade of the pins 25 carried by the different sections when the upper section 1 is unlocked and that pressure is applied between the two ends of the rod . The conformation of the rings 27 comprises, as shown in particular in FIG. 17, an internal chamfer which automatically forces the lugs 25 to disappear in the tubes during the translational movement of said rings and sections relative to each other in the direction folding of the cane.
Selon un mode de réalisation, le tronçon supérieur 1 , destiné à supporter la poignée, est déverrouillé manuellement par déplacement d'un manchon 28 monté coulissant sur le tronçon supérieur 1 de la canne. La figure 16 illustre ce déverrouillage manuel.According to one embodiment, the upper section 1, intended to support the handle, is unlocked manually by moving a sleeve 28 slidably mounted on the upper section 1 of the rod. Figure 16 illustrates this manual unlocking.
Tel que cela est représenté sur la figure 16, le manchon 28 est déplacé manuellement dans le sens de la flèche. Sa forme interne biseautée a pour effet de repousser l'ergot 25 vers son logement avec mise en compression du ressort 26. Une fois l'ergot replié le tube 29, constitutif du tronçon intermédiaire 2, est apte à coulisser à l'intérieur du tube 30, qui forme le tronçon supérieur 1.As shown in Fig. 16, the sleeve 28 is moved manually in the direction of the arrow. Its internal beveled shape has the effect of pushing the lug 25 towards its housing with compression of the spring 26. Once the lug folded the tube 29, constituting the intermediate section 2, is able to slide inside the tube 30, which forms the upper section 1.
Une fois que ce tube 29 a complètement coulissé l'ergot 25 suivant arrive au contact de la bague, laquelle bague chanfreinée se comporte de la même façon vis-à-vis de l'ergot 25 suivant en produisant son repliement dans le tube et en libérant le coulissement de ce dernier dans l'élément déjà replié, tel que cela est illustré sur les figures 17 et 18.Once this tube 29 has completely slid the next pin 16 comes into contact with the ring, which chamfered ring behaves in the same way vis-à-vis the next pin 25 by producing its folding in the tube and in releasing the sliding of the latter in the element already folded, as shown in Figures 17 and 18.
Et ainsi de suite, le repliement s'opère de la même manière pour les différents tronçons pour aboutir à la configuration illustrée sur les figures 13 et 15.And so on, the folding takes place in the same way for the various sections to arrive at the configuration illustrated in Figures 13 and 15.
Avantageusement, selon l'invention, la canne télescopique comporte un ressort de rappel 31 , positionné entre la bague 27 et le manchon 28, sur le tronçon supérieur 1, de manière à permettre audit manchon 28 de revenir dans une position de repos après son actionnement.Advantageously, according to the invention, the telescopic rod comprises a return spring 31, positioned between the ring 27 and the sleeve 28, on the upper section 1, so as to allow said sleeve 28 to return to a rest position after its actuation. .
Les figures 19 à 22 illustrent des vues éclatées des différents tronçons constitutifs d'une canne télescopique comportant, par exemple, quatre tronçons : un tronçon supérieur 1 , deux tronçons intermédiaires 2 identiques et un tronçon inférieur 3. Chaque tronçon est formé par un tube et par différents éléments rapportés.FIGS. 19 to 22 illustrate exploded views of the different constituent sections of a telescopic rod comprising, for example, four sections: an upper section 1, two identical intermediate portions 2 and a lower section 3. Each section is formed by a tube and by different elements reported.
Le tronçon supérieur 1 comporte les différentes pièces déjà décrites précédemment ainsi qu'une douille 32 à baïonnette maintenue serrée collée sur le tube 30. Laquelle douille 32 permet un couplage avec une pièce complémentaire portée par la poignée qui peut ainsi être maintenue de manière ferme mais non définitive sur la canne télescopique. A cet égard, un dispositif à ergot sert au verrouillage de l'accessoire sur la tête de la canne.The upper portion 1 comprises the various parts already described above and a sleeve 32 bayonet held tightly glued to the tube 30. Which sleeve 32 allows a coupling with a complementary part carried by the handle which can thus be maintained firmly but not definitive on the telescopic rod. In this regard, a pin device serves to lock the accessory on the head of the rod.
Un tel dispositif a pour avantage de permettre le remplacement de la poignée, ou une adaptation de cet élément, à la convenance des utilisateurs.Such a device has the advantage of allowing the replacement of the handle, or an adaptation of this element, to the convenience of users.
La figure 21 illustre en vue éclatée un tronçon intermédiaire de la canne et notamment la forme particulière d'un anneau 33 support du logement de l'ergot 25 et du ressort 26. Cette forme, avec un méplat, est associée à un bossage intérieur des tubes pour empêcher la rotation des tronçons entre eux.FIG. 21 illustrates, in exploded view, an intermediate section of the rod and in particular the particular form of a ring 33 supporting the housing of the pin 25 and the spring 26. This shape, with a flat part, is associated with an internal boss of the tubes to prevent rotation of the sections between them.
Selon un mode de réalisation, les tronçons coaxiaux sont guidés lors de leur déplacement en translation pour le repliement et le déploiement et les tubes formant les tronçons sont bloqués en rotation. En particulier, par exemple, l'intérieur de la bague 27 et l'extérieur de l'anneau 33 permettent le guidage droit du tube des tronçons.According to one embodiment, the coaxial sections are guided during their displacement in translation for folding and deployment and the tubes forming the sections are locked in rotation. In particular, for example, the inside of the ring 27 and the outside of the ring 33 allow the straight guide tube sections.
Avantageusement, le dispositif antirotation est obtenu par un bossage intérieur des tubes et est réalisé par la conformation spécifique des anneaux 33 portant les ergots 25.Advantageously, the anti-rotation device is obtained by an internal projection of the tubes and is produced by the specific conformation of the rings 33 carrying the lugs 25.
Les tubes sont guidés intérieurement par l'anneau 33 qui porte l'ergot et par la bague 27 chanfreinée qui permet d'escamoter l'ergot suivant.The tubes are guided internally by the ring 33 which bears the lug and by the chamfered ring 27 which makes it possible to retract the next lug.
Selon un mode de réalisation, la canne télescopique comporte au moins trois tronçons. Toutefois, de manière avantageuse, ladite canne est composée de quatre tronçons, dans laquelle canne, le tronçon supérieur 1 comporte un dispositif permettant de fixer un accessoire tel que notamment une poignée, et le tronçon inférieur 3 comporte un système de couplage 34 pour maintenir un accessoire, lequel accessoire pouvant être, par exemple, un pied ou une pince.According to one embodiment, the telescopic rod comprises at least three sections. However, advantageously, said cane is composed of four sections, wherein cane, the upper portion 1 comprises a device for attaching an accessory such as including a handle, and the lower portion 3 comprises a coupling system 34 for holding an accessory, which accessory may be, for example, a foot or forceps.
Le déploiement de la canne depuis sa position repliée est aisé. Il suffit à l'utilisateur de tirer sur les deux extrémités de la canne pour que les ergots s'enclenchent automatiquement dans leur logement du tronçon adjacent, lorsque l'étirement est complet.The deployment of the cane from its folded position is easy. It is sufficient for the user to pull on both ends of the rod so that the lugs automatically engage in their housing of the adjacent section, when the stretch is complete.
Selon un exemple avantageux de réalisation de l'invention, la canne télescopique est d'une longueur de 250 mm repliée, d'une longueur de 657 mm dépliée pour un diamètre externe maximal au niveau de la section du tronçon supérieur 1 de 33 mm et un diamètre minimal au niveau de la section du tronçon inférieur 3 de 25 mm.According to an advantageous embodiment of the invention, the telescopic rod is of length 250 mm folded, a length of 657 mm unfolded for a maximum external diameter at the section of the upper section 1 of 33 mm and a minimum diameter at the section of the lower section 3 of 25 mm.
