Abstract

The bent and removable device for a blind person's stick according to the invention comprises an end-piece (1) with two holes which are inclined with respect to one another, one at its base for receiving a shaft (2) which supports a ball (3), the second, inclined, in its upper part for the engagement of the stick, the axis of its assembly with the stick forming an angle with the axis of rotation of the ball, a groove connecting, on each side of the base of the second hole, an orifice thereof, situated on its side, to a recess in which the end of the elastic part of the stick is placed. A pin (4) immobilises the shaft supporting the ball.

Description

La présente invention concerne un dispositif coudé et amovible pour canne de non-voyant. The present invention relates to a bent and removable device for blind cane.

Pour se déplacer le non-voyant utilise une canne, soit rigide, soit pliable, avec laquelle il balaie l'espace au devant de lui, le bout de la canne en contact avec le sol. To move the blind uses a cane, either rigid or foldable, with which he sweeps the space in front of him, the end of the cane in contact with the ground.

Actuellement les non-voyants possèdent des cannes avec embout tournant dont l'aie de rotation de celui-ci est le même que celui de la canne et en biais avec le sol. Le point de contact de l'embout tournant sur le sol étant proche de l'aie de la canne, ceci limite la rotation et entraine une usure prématurée avec méplat. Lorsque l'embout tournant est hors d'usage c'est 11 ensemble avec l'élastique qui est à remplacer. Currently the blind have canes with a rotating tip, the rotation of which is the same as that of the cane and at an angle to the ground. The point of contact of the tip rotating on the ground being close to the edge of the rod, this limits rotation and causes premature wear with a flat surface. When the rotating end piece is out of use it is 11 together with the elastic which is to be replaced.

Le dispositif selon l'invention permet de remédier à ces inconvénients. The device according to the invention overcomes these drawbacks.

Il comporte un embout avec deux trous inclinés l'un par rapport à l'autre, l'un à sa base pour le logement d'un axe support d'une boule, le second en pente, dans sa partie supérieure pour l'enmenchement de la canne, l'aie de son assemblage avec la canne formant un angle avec l'aie de rotation de la boule, une rainure reliant de part et d'autre du fond du second trou un orifice de celui-ci situé sur son côté à un évidement dans lequel se place l'extrémité de l'élastique de la canne.It has a tip with two holes inclined relative to each other, one at its base for the housing of a support axis of a ball, the second sloping, in its upper part for engagement of the cane, the area of its assembly with the cane forming an angle with the area of rotation of the ball, a groove connecting on either side of the bottom of the second hole an orifice of the latter located on its side to a recess in which the end of the elastic of the rod is placed.

Avec l'emploi de ce dispositif l'aie de la boule est parallèle au sol. With the use of this device the aie of the ball is parallel to the ground.

Cet aménagement permet d'amener le point de contact boule/sol sur un diamètre perpendiculaire à l'axe de rotation de la boule . chaque effet de ces deux éléments s'additionne à un troisième qui est l'éloignement du point de contact boule/sol de l'aie de rotation ce qui augmente le couple et facilite la rotation de la boule. Le diamètre de l'aie support de la boule étant réduit par rapport à l'ancien système, le couple en est encore augmenté et favorise donc la capacité à tourner de la boule.This arrangement makes it possible to bring the ball / ground contact point to a diameter perpendicular to the axis of rotation of the ball. each effect of these two elements is added to a third which is the distance from the point of contact between the ball and the ground of the rotation surface, which increases the torque and facilitates the rotation of the ball. The diameter of the ball support being reduced compared to the old system, the torque is further increased and therefore promotes the ability to rotate the ball.

La relation par la rainure entre le trou d'emmenchement et la partie située derrière le fond de ce trou permet lors du montage du dispositif, d'assembler l'embout à la canne à l'aide de ltélastique,sans démonter l'élastique de l'intérieur de la canne. Un noeud ou un grossissement quelconque de son extrémité estiseulement nécessaire pour solidariser l'ensemble. The relation by the groove between the engagement hole and the part located behind the bottom of this hole makes it possible during assembly of the device, to assemble the end piece to the rod using the elastic, without dismantling the elastic of inside the cane. Any knot or any enlargement of its end is only necessary to secure the assembly.

Le passage de l'extrémité de l'élastique se faisant d'abord dans le trou puis son orifice sur le c8té pour le placer ensuite dans l'évidement, le tube du bout de la canne venant emprisonner l'élastique, l'extrémité de celui-ci ne peut se dégager de son logement et maintient ensemble les différents éléments; il suffit de retirer le tube et de déplacer l'extrémité de l'élastique pour effectuer le démontage. The passage of the end of the elastic being done first in the hole then its orifice on the side to place it then in the recess, the tube at the end of the rod coming to trap the elastic, the end of it cannot be released from its housing and holds the various elements together; just remove the tube and move the end of the elastic to disassemble.

Avec un axe la boule est maintenue contre la base de l'embout; l'axe est muni d'une tête retenant sur son support la boule assemblée à l'embout. With an axis the ball is held against the base of the tip; the axis is provided with a head retaining on its support the ball assembled with the nozzle.

Une goupille placée dans un logement situé dans l'embout perpendiculairement au trou pour l'aie support de la boule immobilise cet axe; le blocage ou déblocage de l'aie s'effectue par rotation de la goupille, celle-ci restant dans son logement. A pin placed in a housing located in the endpiece perpendicular to the hole for the ball support immobilizes this axis; the blocking or unblocking of the web is done by rotation of the pin, the latter remaining in its housing.

L'assemblage de la boule et de l'embout avec l'axe muni d'une tête, réalisé avec l'emploi d'un tournevis pour la rotation de la goupille,s'effectue aisément et le remplacement seulement de la boule est possible. The assembly of the ball and the tip with the axis provided with a head, carried out with the use of a screwdriver for the rotation of the pin, is easily carried out and the replacement only of the ball is possible .

La goupille peut être un axe avec à un bout une fente pour tournevis et sur le côté un plat qui laisse le passage de l'axe support de la boule; ce peut être également comme représenté sur le dessin une goupille (4) "mécanindus" (marque déposée). The pin can be an axis with at one end a slot for a screwdriver and on the side a flat which allows the passage of the axis supporting the ball; it can also be as shown in the drawing a pin (4) "mechanindus" (registered trademark).

L'axe (2) sera réalisé en acier. The axis (2) will be made of steel.

L'embout (1) et la boule (3) pourront être réalisés en matière plastique, usinée ou en une opération de moulage par injection.  The end piece (1) and the ball (3) can be made of plastic, machined or in an injection molding operation.
