Abstract

Device consisting of a board or platform for exhibiting, simultaneously imparted with movements of ascent or descent, rotation to the left or to the right, and inclination, including a motor 20 driving a shaft 8 and a rod 17, an electromagnet 22 when it receives a current, driving the disc 15 and causing the guide 12 to slide along the rod 14 upwards or downwards depending on the direction of rotation of the motor 20, the secondary arm 6 inclining or righting the board 1.

Description

Le présente invention concerne un dispositif pour permettre, ensemble, l'exbcution de ces trois mouvements, déplacement vertical, horizontal, inclinaison. The present invention relates to a device for enabling, together, the execution of these three movements, vertical, horizontal displacement, inclination.

C'est trois mouvements peuvent etre également désignés par la rotation, l'inclinaison, la montée. It is three movements can also be designated by rotation, tilt, climb.

L'exécution de ces mouvements est traditionnellement éffectué séparément. The execution of these movements is traditionally carried out separately.

Selon le modes particuliers de réalisation:
Le dispositif selon l'invention permet de faire éffectuer ensemble ou séparément, dans la totalité ou parciellement ces trois mouvement,avec un seule dispositif d'entrainement.According to the particular embodiments:
The device according to the invention allows these three movements to be carried out together or separately, in whole or in part, with a single drive device.

Ces mouvements peuvent être réalisés par des dispositifs mécanique, hydraulique, électromécanique, avec un ou plusieurs système d'entrainements. These movements can be carried out by mechanical, hydraulic, electromechanical devices, with one or more drive systems.

Le système d'entrainement retenu ici sera un seule et unique moteur électrique, qui peu tourner dans lee deux sens. The drive system used here will be a single electric motor, which can rotate in both directions.

Le double sens de rotation du moteur, permet le double sens des mouvements droite guauche, montée descente, inclinaison. The double direction of rotation of the motor allows the double direction of movements from right to left, up, down, tilt.

Ce dispositif est adapté ici, à une plateforme,de préférence ayant une forme ronde, au diamètre souhaité. This device is adapted here to a platform, preferably having a round shape, with the desired diameter.

La figure 1 représente l'ensemble du dispositif selon l'invention. Figure 1 shows the entire device according to the invention.

En référence à ce dessin, le dispositif selon l'invention comporte à sa partie supérieur, un plateau(1) de préférence rond muni d'une fixation(2) qui reçoit l'axe(3) pour maintenir les bras articulés(4) et une autre fixation(5) pour maintenir le bras annex(6)
A l'autre extrémité des bras articulée, au centre, b l'articulation(7), se trouve fixé un axe(e) qui descent à l'interieur par le centre , des deux tiges , de l'engrenage et de I'entrai- nement par friction , pour se poser sur un-pivot(9) fixé sur le suport principal(iO), l'axe est retenu par une rondelle(11) servant de butée, pour empêcher l'axe de remonter quand c'est en fonctionnement.Referring to this drawing, the device according to the invention comprises at its upper part, a plate (1) preferably round provided with a fixing (2) which receives the axis (3) to hold the articulated arms (4) and another fixing (5) to hold the adjoining arm (6)
At the other end of the articulated arms, in the center, b the articulation (7), is fixed an axis (e) which descends inside through the center, of the two rods, of the gear and of the friction drive, to land on a pivot (9) fixed on the main support (iO), the axis is retained by a washer (11) serving as a stop, to prevent the axis from going up when it is in operation.

A l'extremité des bras , se trouve fixé, au centre , un guide(12) qui pivot et glisse par un filetage(17) an éllipse le long de la tige(14).  At the end of the arms, there is fixed, in the center, a guide (12) which pivots and slides by a thread (17) an ellipse along the rod (14).

La tige (14) se trouve fixée sur la partie supérieur de la pièce (15) qui repose sur la pièce (16) , sur la partie inféreur du disque (16), se trouve fixé , une deuxième tige (17) qui reçoit à son extrémité, un engrenage (18) ayant un filetage élicoidal qui entraine l'ensemble étant également cixo h l'axe (e). The rod (14) is fixed on the upper part of the part (15) which rests on the part (16), on the lower part of the disc (16), is fixed, a second rod (17) which receives at its end, a gear (18) having an elicoidal thread which drives the assembly also being fixed to the axis (e).

Le guide (12) lorsqu'il est en position base,c'est à dire en bas de la tige (14) fait relever le plateau, avec les bras articulés (4) qui sétirent , le bras annex (6) fait incliner le pla- teau (1)
La longueur du filetage en éllipse (13) qui se trouve sur la tige (14) donne la course du guide (12) ainsi que la distance de la montée du plateau(1) qui peut être en rapport avec la longueur des bras(4).The guide (12) when in the base position, that is to say at the bottom of the rod (14) raises the plate, with the articulated arms (4) which extend, the adjoining arm (6) causes the tray (1)
The length of the elliptical thread (13) which is on the rod (14) gives the stroke of the guide (12) as well as the distance of the rise of the plate (1) which can be related to the length of the arms (4 ).

L'arbre (19) élicoidal du moteur (20) entraine l'engrenage(î8 le moteur (20) se trouve fixé sur le support principal (10). The elicoidal shaft (19) of the motor (20) drives the gear (î8 the motor (20) is fixed on the main support (10).

Le disque (15) prend son sens de rotation, à partirdu moment, ou la bobine (22) se trouve exitée, par le passage d'un courant électrique. The disc (15) takes its direction of rotation, from the moment, or the coil (22) is exited by the passage of an electric current.

L'dlectro-aiment (21) repose sur un support (23) qui se trouve fixé sur le support principal(10)  The electro-like (21) rests on a support (23) which is fixed on the main support (10)
