Description

"Dispositif pour le soulèvement de charges et, notamment pour le soulèvement de meubles et de portes" L'invention concerne un dispositif pour le soulèvement de charges et, notamment pour le soulè¬ vement de meubles et de portes. "Device for lifting loads and, in particular for lifting furniture and doors" The invention relates to a device for lifting loads and, in particular for lifting furniture and doors.
On connaît déjà des dispositifs de ce genre gui se composent d'un profilé, pourvu d'un rebord extérieur destiné à recevoir en appui la charge à sou¬ lever, ce profilé recevant à coulissement intérieur un support pour une embase destinée à s'appuyer sur le sol. Le déplacement du profilé par rapport au support afin de soulever la charge par rapport au sol, est obtenu par un ensemble à levier comprenant un bras de manoeuvre monté pivotant sur le profilé et relié par une biellette au support. Cet ensemble à levier et à biellette qui assure, d'une part le déplacement du support par rapport au profilé et son maintien à 1'intérieur du profilé, est cependant d'une construction fragile compte tenu, notamment, de la présente de la biellette et des différentes articulations dont les portées d'appui sont de surface faible et donc peu résistantes.Devices of this type of mistletoe are already known, which consist of a profile, provided with an outer rim intended to receive the load to be lifted, this profile receiving, with internal sliding, a support for a base intended to be supported. On the ground. The displacement of the profile relative to the support in order to lift the load relative to the ground is obtained by a lever assembly comprising an operating arm pivotally mounted on the profile and connected by a link to the support. This lever and link assembly which ensures, on the one hand the displacement of the support relative to the profile and its maintenance inside the profile, is however of a fragile construction taking into account, in particular, the present of the link and various joints whose bearing surfaces have a small surface area and are therefore not very resistant.
La présente invention a notamment pour but de remédier à ces inconvénients et concerne à cet effet un dispositif de ce type, pour le soulèvement de charges, caractérisé en ce que les moyens à levier reliant le support au profilé sont constitués par une came reliée à une tige de manoeuvre et montée à rotation sur un axe du profilé, cette came s'appuyant par sa périphérie sur le support.The present invention aims in particular to remedy these drawbacks and to this end relates to a device of this type, for lifting loads, characterized in that the lever means connecting the support to the profile consist of a cam connected to an operating rod and mounted for rotation on an axis of the profile, this cam being supported by its periphery on the support.
Suivant une autre caractéristique de 1'in¬ vention, la came s'appuie sur le support par l'intermédiaire d'un rouleau monté à rotation sur un axe du support. Suivant une autre caractéristique de l'in¬ vention, la came est réalisée de façon à présenter un point d'excentricité maximum précédé et suivi par des zones d'excentricité plus faibles, la rotation de la came par la manoeuvre de la tige déplaçant ce point d'excentricité maximum d'un côté à l'autre de son point d'appui sur le support et cela à proximité de l'extrémité de la course de cette came pour laquelle l'écart entre le rebord et l'embase est maximum.According to another characteristic of the invention, the cam rests on the support by means of a roller mounted for rotation on an axis of the support. According to another characteristic of the invention, the cam is produced so as to have a point of maximum eccentricity preceded and followed by weaker zones of eccentricity, the rotation of the cam by the operation of the rod moving this maximum eccentricity point from one side to the other of its support point on the support and this near the end of the travel of this cam for which the gap between the flange and the base is maximum .
L'invention est représentée à titre d'exemple non limitatif sur les dessins ci-joints dans lesquels : la figure 1 est une vue en coupe transversale d'un mode de réalisation du dispositif conforme à l'invention, - la figure 2 est une vue de droite partiellement arrachée de la figure 1,The invention is shown by way of non-limiting example in the accompanying drawings in which: FIG. 1 is a cross-sectional view of an embodiment of the device according to the invention, - FIG. 2 is a right view partially cut away from FIG. 1,
- la figure 3 est une vue correspondant à la figure 1, le levier de manoeuvre ayant été actionné,FIG. 3 is a view corresponding to FIG. 1, the operating lever having been actuated,
- la figure 4 est une vue de dessus de la figure 1.- Figure 4 is a top view of Figure 1.
La présente invention a en conséquence pour but la réalisation d'un dispositif robuste qui permet le soulèvement de charges importantes et qui assure un verrouillage automatique du dispositif en position soulevée de la charge. Ce dispositif comprend ainsi un profilé métallique à section sensiblement carrée 1 qui est pourvu au milieu de l'une de ses faces d'une fente longitudinale 11. Ce profilé, qui est également pourvu d'un rebord extérieur 12/ reçoit à pivotement sur un axe 2 une came 3 réalisée dans l'exemple représenté, sous une forme sensiblement cylindrique. Cette came 3 est actionnée par l'intermédiaire d'un levier de manoeuvre 3τ dont la largeur est telle qu'il peut se déplacer librement dans la fente 1- .The present invention therefore aims to achieve a robust device which allows the lifting of large loads and which provides automatic locking of the device in the raised position of the load. This device thus comprises a metal section with a substantially square section 1 which is provided in the middle of one of its faces with a longitudinal slot 1 1 . This profile, which is also provided with an outer rim 1 2 / receives pivotally on an axis 2 a cam 3 produced in the example shown, in a substantially cylindrical shape. This cam 3 is actuated by means of an operating lever 3τ whose width is such that it can move freely in the slot 1-.
A l'intérieur du profilé 1 est guidé un support 4 réalisé sous la forme d'une pièce en U dont la base 4^ est reliée à l'embase 5 d'appui au sol. Cette liaison est obtenue par l'intermé¬ diaire d'une tige filetée 5, solidaire de l'embase 5 et qui vient se visser dans un noyau 6 à épaulement 6 ce noyau étant d'une longueur suffisante afin d'assurer un montage robuste de l'embase et son guidage parfait dans la pièce 4. Ce noyau 6 est fixé sur la base de la pièce 4 par vissage d'un écrou 62.Inside the profile 1 is guided a support 4 made in the form of a U-shaped part whose base 4 ^ is connected to the base 5 of the ground support. This connection is obtained by the intermediary of a threaded rod 5, integral with the base 5 and which is screwed into a core 6 with shoulder 6 this core being of sufficient length to ensure robust mounting of the base and its perfect guidance in the part 4. This core 6 is fixed to the base of the part 4 by screwing a nut 6 2 .
Les deux branches de la pièce 4 sont reliées par un axe 7 sur lequel est monté à rotation un rouleau 8. La came circulaire 3 s'appuie par sa périphérie sur le rouleau 8 de façon que lors de la manoeuvre de la tige 3 la came 3 s'appuie sur le rouleau 8 en le faisant tourner autour de son axe 7 et déplace la pièce 4 afin d'écarter le rebord 12, qui supporte la charge, de l'embase 5 qui s'appuie au sol. La came circulaire 3 est établie de manière à ce qu'elle présente un point d'excentricité maximum 32 qui est précédé de deux zones d'excentricité moindres 33 et 3A. En outre, la position des axes 2 et 7 et la course de basculement de la tige de manoeuvre 3, sont déterminées de façon que le point d'excentricité maximum 32 passe d'un côté à l'autre du point d'application 8^ de la came 3 sur le rouleau 8 lorsque (voir figure 3) cette came 3 est à proximité de l'extrémité de sa course pour laquelle l'écart entre le rebord 12 et l'embase 5 est maximum, c'est-à- dire dans la position de soulèvement de la charge.The two branches of the part 4 are connected by an axis 7 on which a roller 8 is rotatably mounted. The circular cam 3 is supported by its periphery on the roller 8 so that during the operation of the rod 3 the cam 3 is supported on the roller 8 by rotating it around its axis 7 and moves the part 4 in order to separate the flange 1 2 , which supports the load, from the base 5 which is supported on the ground. The circular cam 3 is established so that it has a maximum eccentricity point 3 2 which is preceded by two lesser eccentricity zones 3 3 and 3 A. In addition, the position of the axes 2 and 7 and the tilting stroke of the operating rod 3 are determined so that the point maximum eccentricity 3 2 passes from one side to the other of the point of application 8 ^ of the cam 3 on the roller 8 when (see FIG. 3) this cam 3 is close to the end of its travel for wherein the gap between the flange 1 2 or the base 5 is maximum, that is to say, in the load lifting position.
Cette disposition constitue donc un verrouillage automatique en position soulevée de la charge, étant donné que la came s'est déplacée au-delà de son point de rebroussement par rapport au rouleau 8 tandis que cette came vient en appui contre la face interne du profilé 1.This arrangement therefore constitutes an automatic locking in the raised position of the load, since the cam has moved beyond its cusp with respect to the roller 8 while this cam comes to bear against the internal face of the profile 1 .
Le rebord 12 qui, soit fait partie inté¬ grante du profilé 1, soit constitue la branche d'une équerre rapportée contre ce profilé, est destiné à se placer sous la charge. Il est cependant possible que la base de cette charge présente un rebord en saillie à sa base, comme c'est souvent le cas des meubles. Afin d'éviter le basculement du dispositif lors du soulèvement d'un tel meuble, il est prévu sur le profilé 1 une butée réglable 10 constituée par une lame pliée en U dont les branches se logent à coulissement dans deux plots 11 fixés sur la face externe du profilé 1 sur des prolongements de l'axe 2. Des vis pointeau 12 sont prévues pour immobiliser la butée 10 de façon que sa branche 10, soit située à une distance du profilé 1 qui correspond à l'épaisseur du rebord en saillie du meuble à soulever.The rim 1 2 which either forms an integral part of the section 1, or constitutes the branch of a bracket added against this section, is intended to be placed under the load. However, it is possible that the base of this load has a protruding rim at its base, as is often the case with furniture. In order to avoid tilting of the device during the lifting of such a piece of furniture, there is provided on the profile 1 an adjustable stop 10 constituted by a blade folded in a U, the branches of which slide into two studs 11 fixed on the face profile 1 on the extensions of the axis 2. Needle screws 12 are provided to immobilize the stop 10 so that its branch 10 is located at a distance from the profile 1 which corresponds to the thickness of the protruding rim of the furniture to lift.
Dans l'exemple représenté sur les dessins, le profilé est pourvu de deux tiges 9 de renforcement, ces tiges placées entre le rouleau 8 et la base 4t du U constituant également un organe de retenue du U dans le profilé 1. In the example shown in the drawings, the profile is provided with two reinforcing rods 9, these rods placed between the roller 8 and the base 4 t of the U also constituting a retaining member of the U in the profile 1.
