Description

La présente invention se rapporte à un embout de canne antidérapant.The present invention relates to a non-slip cane tip.

Pour amortir les chocs, les cannes et les béquilles sont munies d'un embout en élastomère. Un tel embout comporte un manchon dans lequel vient s'emboîter la partie terminale d'une canne et une embase de contact avec le sol, constitué par exemple par un silentbloc cylindrique. L'utilisateur ne peut cependant se déplacer en toute sécurité sur la plupart des sols, qui peuvent être glissants ou caillouteux ou présenter des surfaces inégales. Une instabilité résulte d'un manque d'adhérence au sol due à une seule zone d'appui insuffisante et aléatoire : lorsque l'utilisateur avance, la canne tourne autour de son point d'appui d'une inclination arrière vers une inclination avant, l'articulation de la canne par rapport au sol s'opérant par changement de zone d'appui. De plus, si l'on cherche à augmenter la surface de contact avec le sol pour augmenter l'adhérence et la stabilité, l'embout perd en souplesse et le taux d'usure s'accroit.To absorb shocks, canes and crutches are fitted with an elastomer tip. Such a nozzle comprises a sleeve into which the end part of a cane fits and a contact base with the ground, constituted for example by a cylindrical silentbloc. However, the user cannot move around safely on most floors, which can be slippery or stony or have uneven surfaces. Instability results from a lack of grip on the ground due to a single insufficient and random support zone: when the user advances, the rod turns around its support point from a rear inclination to a front inclination, the articulation of the rod relative to the ground operating by changing the support zone. In addition, if we seek to increase the contact surface with the ground to increase grip and stability, the tip loses flexibility and the wear rate increases.

La présente invention a pour but de pallier ces inconvénients, en proposant un embout de canne antidérapant en élastomère conçu pour garantir une meilleure stabilité et un meilleur confort à l'utilisateur.The present invention aims to overcome these drawbacks, by providing a non-slip elastomeric cane tip designed to guarantee better stability and better comfort for the user.

A cet effet, elle propose un embout de canne en élastomère du genre comportant un manchon adapté à s'emboîter avec une partie terminale de canne et une embase de contact avec le sol, caractérisé en ce qu'il présente en succession de haut en bas, une zone rigide de ceinturage, une zone souple d'articulation, un corps d'embase rigide et un ensemble d'éléments saillants souples antidérapants de contact avec le sol.To this end, it offers an elastomeric cane tip of the kind comprising a sleeve adapted to fit together with a cane end portion and a base contacting the ground, characterized in that it presents in succession from top to bottom , a rigid belt area, a flexible articulation zone, a rigid base body and a set of flexible non-slip projecting elements in contact with the ground.

Grâce à cette disposition de l'invention, il devient possible d'avoir une articulation de la canne par rapport au sol, non plus par rotation angulaire avec changement de zone d'appui au sol, mais par rotation angulaire de la zone souple d'articulation du manchon autour du corps de l'embase rigide. Le corps de l'embase demeure parallèle au sol et au contact de celui-ci dans la majorité des cas. De plus, le corps de l'embase étant rigide et le contact avec le sol se faisant selon la présente invention par l'intermédiaire d'éléments saillants antidérapants, il devient possible d'augmenter la surface du corps de l'embase en dehors de la projection du manchon et de gagner ainsi en stabilité. L'adhérence de l'embout au sol est également améliorée grâce à l'ensemble d'éléments antidérapants multipliant la possibilité de point d'appui avec le sol. Selon des caractéristiques préférentielles, le corps de l'embase présente une forme cylindrique à directrice trilobée et les éléments antidérapants sont constitués par des plots souples de contact avec le sol. Selon d'autres caractéristiques préférentielles, l'embout en élastomère est réalisé d'un seul tenant par moulage.Thanks to this arrangement of the invention, it becomes possible to have an articulation of the rod with respect to the ground, no longer by angular rotation with change of support zone on the ground, but by angular rotation of the flexible zone of articulation of the sleeve around the body of the rigid base. The body of the base remains parallel to the ground and in contact with it in most cases. In addition, the body of the base being rigid and the contact with the ground being made according to the present invention by means of non-slip projecting elements, it becomes possible to increase the surface of the body of the base outside the projection of the sleeve and gain stability. The grip of the nozzle on the ground is also improved thanks to the set of non-slip elements increasing the possibility of a fulcrum with the ground. According to preferential characteristics, the body of the base has a cylindrical shape with a three-lobed director and the non-slip elements consist of flexible pads in contact with the ground. According to other preferred characteristics, the elastomer end piece is made in one piece by molding.

L'invention sera mieux comprise à la lumière de la description qui va suivre, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels :

  • la figure 1 illustre une vue en élévation d'un embout de canne selon un exemple de réalisation de l'invention;
  • la figure 2 illustre une vue du dessus de l'embout selon la flèche II de la figure 1.
The invention will be better understood in the light of the description which follows, given solely by way of example and made with reference to the appended drawings in which:
  • Figure 1 illustrates an elevational view of a cane tip according to an exemplary embodiment of the invention;
  • FIG. 2 illustrates a top view of the end-piece according to arrow II in FIG. 1.

Dans l'exemple de réalisation choisi et représenté aux figures 1 et 2, l'embout de canne est réalisé en EPDM d'un seul tenant par moulage, avec différentes charges de poudre de carbone réparties de manière à obtenir de bas en haut la succession de zone souple et de zone rigide. Des additifs sont également ajoutés pour garantir des qualités de résistances à l'usure, à l'attaque d'agents chimiques, aux rayons UV et à l'ozone. Les zones rigides ont une dureté d'environ 85° shores et les zones souples d'environ 55° shores.In the embodiment chosen and shown in Figures 1 and 2, the cane tip is made of EPDM in one piece by molding, with different charges of carbon powder distributed so as to obtain from the bottom up the succession flexible zone and rigid zone. Additives are also added to guarantee qualities of resistance to wear, to attack by chemical agents, to UV rays and to ozone. The rigid zones have a hardness of approximately 85 ° shores and the flexible zones of approximately 55 ° shores.

L'embout est formé d'un manchon 5 et d'une embase 6 de contact avec le sol. Il comporte successivement de haut en bas, une zone rigide 1 de ceinturage, adaptée à maintenir la tige d'une canne (non représentée), une zone souple 2 d'articulation du manchon par rapport à l'embase, une zone rigide formant un corps d'embase 3 et une zone d'éléments saillants souples antidérapants constitués par un ensemble de plots, tels que 4.The tip is formed by a sleeve 5 and a base 6 for contact with the ground. It successively comprises from top to bottom, a rigid belt area 1, adapted to hold the rod of a rod (not shown), a flexible zone 2 for articulation of the sleeve relative to the base, a rigid zone forming a base body 3 and a zone of flexible non-slip projecting elements constituted by a set of studs, such as 4.

Le manchon 5 est constitué par la zone de ceinturage 1 et la zone d'articulation 2 laquelle présente une partie inférieure 7 de diamètre élargi. A l'intérieur du manchon est défini un logement cylindrique 8 d'assemblage avec la partie terminale d'une canne, s'étendant jusqu'au corps 3 de l'embase.The sleeve 5 is formed by the belt area 1 and the articulation zone 2 which has a lower part 7 of enlarged diameter. Inside the sleeve is defined a cylindrical housing 8 for assembly with the end part of a rod, extending to the body 3 of the base.

Le corps 3 de l'embase 6 présente une forme cylindrique à directrice trilobée et s'étend en dehors de la projection du manchon. Les trois lobes tels que 9, sont identiques et forment un "trèfle". Les plots 4 sont disposés par paire sous chaque lobe, chacun de part et d'autre d'une ligne radiale médiane M à proximité de la périphérie du lobe correspondant.The body 3 of the base 6 has a cylindrical shape with a three-lobed director and extends outside the projection of the sleeve. The three lobes such as 9, are identical and form a "clover". The pads 4 are arranged in pairs under each lobe, each on either side of a median radial line M near the periphery of the corresponding lobe.

La partie terminale d'une canne est placée dans le manchon 5 de l'embout en surmontant une déformation élastique de celui-ci. La zone de ceinturage du manchon par sa rigidité permet un maintien ferme de la tige de la canne. La zone d'articulation, située entre deux zones rigides, la zone de ceinturage et le corps de l'embase, par sa souplesse et sa flexibilité permet un débattement angulaire de la canne suffisant pour que le corps de l'embase rigide puisse rester pratiquement horizontal dans une majorité des cas. Les éléments saillants sont constitués d'un ensemble de plots de petit diamètre, de dureté faible, présentant ainsi un ensemble de surfaces de contact avec le sol permettant une meilleure adhérence et résistance à l'usure. Leur dimension et leur disposition par paire permet une meilleure adaptabilité aux sols : ainsi deux plots peuvent par exemple enserrer un obstacle et/ou s'adapter à la forme de celui-ci.The end part of a rod is placed in the sleeve 5 of the end piece overcoming an elastic deformation of the latter. The rigidity of the sleeve's belt area allows firm support for the rod. The articulation zone, located between two rigid zones, the belt zone and the body of the base, by its suppleness and flexibility allows an angular movement of the rod sufficient for the body of the rigid base to remain practically horizontal in most cases. The projecting elements consist of a set of small diameter studs, of low hardness, thus presenting a set of contact surfaces with the ground allowing better adhesion and resistance to wear. Their size and arrangement in pairs allows better adaptability to the soil: two studs can for example enclose an obstacle and / or adapt to its shape.

La forme préférentielle avec trois lobes du corps de l'embase contribue également à l'amélioration de la stabilité : un des lobes pouvant se trouver soulevé par exemple par un obstacle, n'empêchera pas les deux autres de rester en contact avec le sol, de sorte que l'ensemble restera stable.The preferential shape with three lobes of the body of the base also contributes to the improvement of stability: one of the lobes being able to be raised for example by an obstacle, will not prevent the two others from remaining in contact with the ground, so that the whole will remain stable.

Un tel embout permet à l'utilisateur de se déplacer avec plus de sécurité sur la plupart des sols. Selon une variante, l'embout peut être réalisé en trois parties, un manchon rigide dans lequel on positionne la canne, un silentbloc formant la zone d'articulation souple et un corps d'embase rigide muni d'éléments saillants souples, l'ensemble étant maintenu par des moyens de fixation appropriés.Such a tip allows the user to move more safely on most floors. According to a variant, the end piece can be made in three parts, a rigid sleeve in which the rod is positioned, a silentbloc forming the flexible articulation zone and a rigid base body provided with flexible projecting elements, the assembly being held by suitable fixing means.

Selon d'autres variantes, l'embout peut être réalisé avec d'autres élastomères et d'autres agents durcisseurs appropriés. Le corps de l'embase ainsi que les éléments saillants antidérapants peuvent également prendre une toute autre forme.According to other variants, the tip can be produced with other elastomers and other suitable hardening agents. The body of the base as well as the non-slip projecting elements can also take a completely different shape.

Il va de soi que la présente invention n'a été décrite qu'à titre explicatif et nullement limitatif.It goes without saying that the present invention has been described for explanatory purposes and in no way limitative.
