Description

La présente invention a pour objet un appareil d'aide à la marche, notamment une canne.The present invention relates to an apparatus for aiding walking, including a cane.

Un appareil d'aide à la marche tel qu'une canne comprend un corps de forme rectiligne ou sensiblement rectiligne, dont une extrémité, l'extrémité supérieure, comporte un moyen de préhension et d'appui, tandis que l'autre extrémité, l'extrémité inférieure, est munie d'un embout ayant une fonction antidérapante.A walking aid apparatus such as a rod comprises a body of rectilinear or substantially rectilinear shape, one end of which, the upper end, comprises a means of grip and support, while the other end, lower end, is provided with a tip having a non-slip function.

Une canne présente essentiellement deux inconvénients, d'une part celui de nécessiter d'avoir à se baisser jusqu'au sol pour la ramasser lorsqu'elle est tombée, et d'autre part celui d'avoir à trouver une surface verticale pour la poser en appui si on ne veut pas qu'elle tombe au sol.A cane has two main drawbacks, on the one hand that of having to bend down to the ground to pick it when it has fallen, and secondly to have to find a vertical surface to ask in support if we do not want it to fall to the ground.

On connaît déjà des cannes dont l'embout de l'extrémité inférieure est muni d'un élargissement sous forme d'un disque coaxial à la canne, destiné à constituer un levier permettant, lorsque la canne est au sol et qu'on exerce sur ledit disque une pression sensiblement verticale, de provoquer le relèvement de la canne.Canes are already known whose tip of the lower end is provided with an enlargement in the form of a disc coaxial with the cane, intended to constitute a lever allowing, when the cane is on the ground and that is exerted on said disk a substantially vertical pressure, to cause the raising of the cane.

Une telle canne présente cependant un inconvénient, celui de nécessiter un effort important, ou contrôlé pendant toute l'opération, pour faire se relever la canne, en sorte que le redressement de la canne est brusque et rapide, et que l'utilisateur peut ne pas pouvoir l'attraper lorsqu'elle se redresse, d'autant plus que les personnes qui généralement ont besoin d'une canne présentent des difficultés motrices.Such a rod has however a drawback, that of requiring a large effort, or controlled throughout the operation, to raise the cane, so that the recovery of the cane is sudden and fast, and that the user can not not being able to catch it when it is recovering, especially since people who generally need a cane present motor difficulties.

On connaît également des cannes auto-redressables équipées de moyens permettant qu'elles se maintiennent toujours à la verticale, c'est le cas de la canne décrite dans le document EP 0 661 010 . L'extrémité inférieure de cette canne est équipée d'un élément présentant inférieurement et périphériquement une surface convexe définissant un point de rotation, tandis que du fait d'un lest, le centre de gravité de la canne est situé en dessous dudit point de rotation.Self-straightening rods are also known which are equipped with means enabling them to always be held vertically, this being the case with the cane described in the document EP 0 661 010 . The lower end of this rod is equipped with an element having inferiorly and peripherally a convex surface defining a point of rotation, whereas due to a ballast, the center of gravity of the rod is located below said point of rotation .

Si une telle canne est effectivement auto-redressable, et demeure toujours à la verticale, elle apparaît toutefois, du fait de l'encombrement de son extrémité inférieure, d'un usage peu pratique dans sa fonction de base, à savoir l'aide à la marche.If such a cane is indeed self-healing, and still remains vertical, it appears however, due to the congestion of its lower end, a use impractical in its basic function, namely the assistance to walking.

On connaît également des cannes permettant d'assurer une certaine stabilité en utilisation, et leur maintien en position verticale sans appui. Ces cannes, décrites par exemple dans les documents US 5 992 434 , FR 2 668 690 , DE 203 09 568 et WO 99/35930 , comportent toutes à leur extrémité un embout muni d'une face plane d'appui, qui s'étend dans un plan perpendiculaire à l'axe principal de la canne.Also known rods to ensure a certain stability in use, and maintaining vertical position without support. These rods, described for example in the documents US 5,992,434 , FR 2,668,690 , DE 203 09 568 and WO 99/35930 , all have at their end a tip provided with a flat bearing face, which extends in a plane perpendicular to the main axis of the rod.

Si les cannes décrites dans ces documents comportent des caractéristiques qui leur permettent d'assurer d'une part une certaine stabilité en utilisation, et d'autre part un maintien en position verticale sans appui, elles présentent toutefois un inconvénient. En effet leur semelle plate impose, après une tentative de redressement au pied de la canne, ou lors du positionnement de cette dernière à verticale en vue de son maintien sans appui, d'opérer avec des gestes très précis afin que ladite semelle plate soit parfaitement au contact du sol, et d'éviter des mouvements d'oscillation susceptibles de provoquer son basculement.If the rods described in these documents have features that allow them to ensure on the one hand a certain stability in use, and secondly a vertical position without support, however, they have a disadvantage. Indeed their flat sole requires, after an attempt at recovery at the foot of the cane, or when positioning the latter to vertical to maintain it without support, to operate with very precise gestures so that said flat sole is perfectly in contact with the ground, and to avoid oscillation movements likely to cause it to tilt.

La présente invention a pour but de proposer une canne permettant de remédier aux divers inconvénients précités.The present invention aims to provide a cane to overcome the various aforementioned drawbacks.

La canne selon l'invention comporte un fût de forme rectiligne ou sensiblement rectiligne, une extrémité supérieure comprenant une poignée pour la préhension et l'appui, et une extrémité inférieure munie d'un embout ayant une fonction antidérapante, et qui présente un élargissement sous forme d'un disque coaxial à la canne, destiné à constituer un levier apte à permettre le relèvement lors de l'application d'une pression, et il se caractérise en ce que ledit fût et ladite poignée sont réalisés dans un matériau léger, et en ce que ledit embout renferme un lest, en sorte d'amener le centre de gravité de ladite canne au plus proche de ladite extrémité inférieure, tandis que ledit embout présente une paroi extrême de forme convexe.The rod according to the invention comprises a shaft of rectilinear or substantially straight shape, an upper end comprising a handle for gripping and support, and a lower end provided with a tip having a non-slip function, and which has a widening under form of a coaxial disc to the rod, intended to constitute a lever adapted to allow the raising during the application of pressure, and it is characterized in that said shaft and said handle are made of a light material, and in that said tip contains a ballast, so as to bring the center of gravity of said rod to the nearest of said lower end, while said tip has an end wall of convex shape.

Le positionnement du centre de gravité à proximité de l'extrémité inférieure, combiné à la forme de disque de l'embout, permet le relevage de la canne en exerçant un appui sur le bord dudit embout, sans que cela nécessite un effort important, ni un contrôle particulier de cet effort.The positioning of the center of gravity near the lower end, combined with the disc shape of the tip, allows the lifting of the cane by exerting a bearing on the edge of said tip, without this requiring significant effort, nor special control of this effort.

Le centre de gravité n'est pas suffisamment bas pour permettre le relevage automatique de la canne lorsqu'elle est posée au sol, mais il est suffisamment bas pour assister le relevage de la canne, assurer ce relevage à partir d'un certain angle d'inclinaison avec l'horizontale, et assurer sa stabilité lorsqu'elle est positionnée à la verticale.The center of gravity is not low enough to allow automatic lifting of the cane when it is placed on the ground, but it is low enough to assist the lifting of the cane, ensure this lift from a certain angle of tilt with the horizontal, and ensure its stability when positioned vertically.

La forme convexe de l'extrémité de l'embout permet d'amortir le relèvement, en offrant une multitude de positions stables, contrairement à une semelle plate qui n'en offre qu'une qui peut parfois être difficile à trouver.The convex shape of the end of the tip helps cushion the bearing, offering a multitude of stable positions, unlike a flat sole that offers only one that can sometimes be difficult to find.

Selon une caractéristique additionnelle de la canne selon l'invention, la paroi extrême de l'embout est en forme de calotte sphérique.According to an additional characteristic of the rod according to the invention, the end wall of the tip is in the form of a spherical cap.

Selon une autre caractéristique additionnelle de la canne selon l'invention, l'embout présente une paroi périphérique de forme tronconique, allant en rétrécissant vers l'extrémité.According to another additional feature of the rod according to the invention, the tip has a peripheral wall of frustoconical shape, narrowing towards the end.

Selon une autre caractéristique additionnelle de la canne selon l'invention, le bord supérieur de la paroi périphérique est relié au fût au travers d'une partie intermédiaire en forme de trompette.According to another additional feature of the rod according to the invention, the upper edge of the peripheral wall is connected to the barrel through a trumpet-shaped intermediate portion.

Du point de vue fabrication, le fût et la poignée sont réalisés dans un matériau composite, à savoir une matière plastique de préférence chargée en fibres, par exemple du polycarbonate chargé fibres de verre.From the point of view of manufacture, the barrel and the handle are made of a composite material, namely a plastic material preferably loaded with fibers, for example polycarbonate loaded with glass fibers.

L'embout est constitué de fonte, formant le lest, recouverte d'un élastomère, mais dans une version préférée, et de manière avantageuse, le lest consiste en des accus, utilisés pour faire fonctionner une électronique embarquée telle que du matériel de localisation, et/ou de comptage.The tip consists of cast iron, forming the ballast, covered with an elastomer, but in a preferred version, and advantageously, the ballast consists of batteries, used to operate an on-board electronics such as location equipment, and / or counting.

Les avantages et les caractéristiques de la canne selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the rod according to the invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

  • la figure 2 représente une vue schématique en coupe longitudinale médiane d'une partie de la même canne.
  • les figures 3a, 3b, 3c et 3d représentent des vues schématiques en élévation d'une partie de la même canne dans des phases d'utilisation différentes.
In the attached drawing:
  • the figure 1 is a schematic elevational view of a rod according to the invention.
  • the figure 2 represents a schematic view in median longitudinal section of a portion of the same cane.
  • the Figures 3a, 3b, 3c and 3d represent schematic views in elevation of part of the same cane in different phases of use.

En référence à la figure 1, on peut voir une canne 1 selon l'invention, qui comporte essentiellement un fût 10 rectiligne ou sensiblement rectiligne, une extrémité supérieure 11 consistant en une poignée en forme de crosse, et à son extrémité inférieure 12 un embout 2.With reference to the figure 1 , there can be seen a rod 1 according to the invention, which essentially comprises a straight or substantially rectilinear shaft 10, an upper end 11 consisting of a grip-shaped handle, and at its lower end 12 a tip 2.

L'embout 2 se présente sous la forme d'un disque coaxial au fût 10, et d'un diamètre bien supérieur à celui du fût 10, en sorte de créer un élargissement périphérique susceptible de servir de levier.The tip 2 is in the form of a disc coaxial with the barrel 10, and a diameter much greater than that of the barrel 10, so as to create a peripheral expansion that can serve as a lever.

En référence à la figure 2, on peut voir plus en détail l'extrémité inférieure 12 de la canne 1 et l'embout 2.With reference to the figure 2 , we can see in more detail the lower end 12 of the rod 1 and the tip 2.

L'embout 2 présente une paroi extrême 20 légèrement bombée, en forme de calotte sphérique de grand rayon de courbure, et une paroi périphérique 21 de forme tronconique, allant en rétrécissant vers l'extrémité, c'est-à-dire que le bord supérieur 23 de la paroi 21 consiste en un cercle d'un diamètre supérieur à celui que constitue le bord inférieur 24 de cette paroi.The tip 2 has a slightly convex end wall 20, in the form of a spherical cap with a large radius of curvature, and a peripheral wall 21 of frustoconical shape, narrowing towards the end, that is to say that the edge upper 23 of the wall 21 consists of a circle with a diameter greater than that constituted by the lower edge 24 of this wall.

Par ailleurs, la jonction entre le bord supérieur 23 de la paroi 21, et le fût 10, est réalisée au travers d'une partie intermédiaire 25 en forme de trompette.Furthermore, the junction between the upper edge 23 of the wall 21, and the shaft 10, is formed through an intermediate portion 25 trumpet-shaped.

L'embout 2 est essentiellement constitué d'un lest 3 recouvert d'une couche 22 d'un matériau élastomère, qui forme notamment les parois 20 et 21.The tip 2 essentially consists of a ballast 3 covered with a layer 22 of an elastomeric material, which forms in particular the walls 20 and 21.

Le lest 3 est destiné à abaisser le centre de gravité de la canne 1 au plus près de l'extrémité inférieure 12. Il peut consister en une masse métallique telle de la fonte, ou bien, de manière préférentielle en des accus destinés à alimenter une électronique embarquée.The ballast 3 is intended to lower the center of gravity of the rod 1 closer to the lower end 12. It may consist of a metal mass such as cast iron, or, preferably in batteries to feed a embedded electronics.

En effet il est possible de prévoir dans une canne des moyens de localisation, des moyens d'émission d'un signal d'alarme, ou bien des moyens de mesure divers, un podomètre par exemple.Indeed it is possible to provide in a cane locating means, means for transmitting an alarm signal, or various measuring means, a pedometer for example.

En référence maintenant aux figures 3a, 3b, 3c et 3d, on peut voir l'utilité des caractéristiques de la canne 1 selon l'invention.Referring now to Figures 3a, 3b, 3c and 3d we can see the usefulness of the characteristics of the cane 1 according to the invention.

Sur ces figures on peut voir l'extrémité inférieure 12 de la canne 1, lors de trois phases successives de son redressement lorsque l'on exerce une pression P, avec le pied par exemple, sur l'embout 2, en se servant de celui-ci comme levier.In these figures we can see the lower end 12 of the rod 1, in three successive phases of its recovery when exerting a pressure P, with the foot for example, on the tip 2, using the one as a lever.

Sur ces figures, on a représenté le centre de gravité G de la canne 1, situé au niveau du fût 10 à proximité de l'extrémité inférieure 12. La position du centre de gravité G dépend évidemment de la longueur du fût 10, de la nature du matériau dont sont faits le fût 10 et la poignée 11, ainsi que des dimensions et de la nature du lest 3, non visible.In these figures, there is shown the center of gravity G of the rod 1, located at the barrel 10 near the lower end 12. The position of the center of gravity G obviously depends on the length of the barrel 10, the nature of the material of which are made the shaft 10 and the handle 11, as well as dimensions and the nature of the ballast 3, not visible.

Sur la figure 3a, la canne 1 repose sur le sol S, entre sont extrémité supérieure 11, non visible, et l'embout 2, ou plus exactement en un point de l'arête que forme le bord 23.On the figure 3a , the rod 1 rests on the ground S, between its upper end 11, not visible, and the tip 2, or more exactly at a point on the edge formed by the edge 23.

Sur la figure 3b, on peut voir qu'en exerçant une pression P sur le dessus de l'embout 2, au niveau de l'arête 23 en une zone diamétralement opposée à celle en contact avec le sol S, on provoque, par un effet de levier, la remontée du fût 10.On the figure 3b it can be seen that by exerting a pressure P on the top of the tip 2, at the edge 23 in a zone diametrically opposite to that in contact with the ground S, it is caused, by a lever effect, the raising of the shaft 10.

Le redressement est obtenu par le pivotement de l'embout 2 selon l'arête 23, jusqu'à ce que, dans un premier temps, l'embout 2 repose au sol S par sa paroi périphérique 21.The straightening is obtained by the pivoting of the tip 2 along the edge 23, until, at first, the tip 2 rests on the ground S by its peripheral wall 21.

Sur la figure 3c, on peut voir qu'en prolongeant la pression P, on provoque la poursuite du redressement du fût 10, par pivotement selon l'arête que forme le bord 24, jusqu'à ce que la paroi 20 soit en contact avec le sol S, comme cela est visible sur la figure 3d.On the figure 3c it can be seen that, by prolonging the pressure P, it provokes the continuation of the straightening of the drum 10, by pivoting along the edge formed by the edge 24, until that the wall 20 is in contact with the ground S, as is visible on the figure 3d .

Le positionnement du centre de gravité G à proximité de l'embout 2 autorise une manipulation aisée de la canne 1, la pression à exercer est minime, elle diminue le porte-à-faux et favorise le contrôle du redressement.The positioning of the center of gravity G near the tip 2 allows easy manipulation of the rod 1, the pressure to be exerted is minimal, it decreases the cantilever and promotes the control of recovery.

On notera que la forme en trompette de la partie intermédiaire 25, présente un certain confort d'utilisation, pour appliquer la pression P avec le pied.Note that the trumpet shape of the intermediate portion 25, has a certain comfort of use, to apply the pressure P with the foot.

Par ailleurs, la canne 1 peut demeurer en position verticale sans nécessiter de prise d'appui contre une surface quelconque, du fait du positionnement du centre de gravité G, et du grand rayon de courbure de la paroi 20.Furthermore, the rod 1 can remain in a vertical position without the need to take any support against any surface, because of the positioning of the center of gravity G, and the large radius of curvature of the wall 20.

La forme convexe de la paroi 20 permet à la canne 1 de se stabiliser dans sa position d'équilibre, laquelle ne correspond pas obligatoirement à la verticalité du fût 10.The convex shape of the wall 20 allows the rod 1 to stabilize in its equilibrium position, which does not necessarily correspond to the verticality of the barrel 10.

Ainsi, avec un peu d'entraînement l'utilisateur peut être capable de redresser une canne 1 selon l'invention tombée au sol, pour l'amener dans une position verticale, et la maintenir dans cette position, sans qu'il soit nécessaire qu'il utilise ses mains.Thus, with a little drive the user may be able to straighten a cane 1 according to the invention fallen to the ground, to bring it into a vertical position, and maintain it in this position, without it being necessary that he uses his hands.
