Abstract

The device has a plate, and lower and upper frames (1, 2) overlapped with respect to each other. The two frames are articulated by two knuckles (3) without axles permitting the frames to pivot with respect to each other. The knuckles comprise two disks which are assembled by a squared section ring made of friction polymer, and a cord is fixed on the frame (1). One of the frames is fixed to the ground by two fixation plates (6) at its lower end and is in sliding connection with respect to the plate by its upper end.

Description

La presente invention concerne un dispositif pour elever une table aThe present invention relates to a device for raising a table a

plusieurs hauteurs. le dispositif selon !'invention comporte plusieurs caracteristiques permettant le levage dune table. Une cordelette par I'intermediaire d'une poulie de renvoi demultipliant !'effort par 2 permet en meme temps qu'une traction vers le haut de la table d'enclencher le levage de la table. La table peut ainsi se positionner de table basse a table haute avec toutes positions intermediaires possibles. La cordelette de levage se bloque dans un taquet coinceur. Une deuxieme 10 cordelette de securite coulisse dans un bloqueur pour eviter une descente brutale. Les dessins annexes illustrent ('invention, le plan 1 represente en coupe le dispositif. Le plan 2 represente la vue de dessus, systeme ferme, montrant les 2 cadres s'imbriquant run dans ratite. Chaque cadre etant compose de 15 quatre tubes en aluminium de section rectangulaire, assembles par I'intermediaire d'equerres en fonderie d'aluminium (plans 4 et 5). Ces equerres de part leur conception sont reversible gauche droite, deux usinages sont necessaires pour loger un axe commun a une roulette (8) ou une platine de fixation (6) 20 En reference a ces dessins le dispositif comporte 2 cadres (1) et (2). Ces 2 cadres sont relies par 2 rotules (3) voir details plan 3. Ces 2 rotules, qui font !'objet de ('invention ne comportent pas d'axe et sont constituees de chacune de 2 disques comportant 2 fraisages en demi-creux, ('assemblage de ces deux disques se faisant par un anneau de section carree en polymere de friction, 25 avec suffisament de jeu pour que les deux disques puissent pivoter run par rapport a I'autre. Le cadre est fixe sur le sol par I'intermediaire de deux platines (6) articulees en bout du cadre (1). La fixation sous la table se fait par deux platines (6) articulees en bout du cadre (2). Lors de !'elevation de la table (voir plan 1), 30 I' X du mecanisme porte sur le sol sur deux roulettes fixees en bout du cadre (1) et sous la table par deux autres roulettes fixees en bout du cadre (2). Pour elever la table , une cordelette fixee sur le cadre (1) au milieu de la largeur of se situent les platines (6) rejoint la poulie de renvoi (4) situee sur le cadre (2) puis revient vers le point d'attache, passant dans un taquet 35 coinceur (9). Une cordelette de securite non representee double la securite du taquet coinceur, se fixant dans un coinceur a cote du taquet coinceur.  several heights. the device according to the invention has several features for lifting a table. A cord through a pulley multiplying multiplier effort 2 allows at the same time a pull up the table to engage the lifting of the table. The table can thus be positioned from coffee table to high table with all possible intermediate positions. The lifting rope hangs in a jam cleat. A second safety cord 10 slides in a blocker to avoid a sudden descent. The accompanying drawings illustrate the invention, the plane 1 represents in section the device The plane 2 represents the top view, closed system, showing the 2 frames interlocking run in ratite Each frame being composed of four aluminum tubes of rectangular section, assembled by means of squares in aluminum foundry (planes 4 and 5) These squares by their design are reversible left right, two machining are necessary to accommodate a common axis to a roulette (8) or a mounting plate (6) With reference to these drawings the device comprises 2 frames (1) and (2) These 2 frames are connected by 2 ball joints (3) see details plan 3. These 2 ball joints, which make! The object of the invention does not have an axis and consist of each of two disks having two semi-hollow millings, the assembly of these two disks being made by a ring of square section made of friction polymer, with enough game so that both discs can rotate run in relation to each other. The frame is fixed on the ground by means of two plates (6) articulated at the end of the frame (1). The fixing under the table is done by two plates (6) articulated at the end of the frame (2). At the raising of the table (see plan 1), 30 I X of the mechanism is on the floor on two wheels fixed at the end of the frame (1) and under the table by two other wheels fixed at the end of the frame (2 ). To raise the table, a cord fixed on the frame (1) in the middle of the width of are located the plates (6) joins the deflection pulley (4) located on the frame (2) and then returns to the point of attachment passing in a camming cleat (9). An unrepresented safety cord doubles the safety of the jam cleat, fixing itself in a jam next to the jam cleat.
