Abstract

The device has a rectangular dish which pivots on a base and supports a frame through two pairs of arms. Each pair of arms is joined by a pivot which runners at the ends engage in slides to allow the dish to be varied in height as the arms pivot. Two gas jacks working in compression modes articulate on a common axis to which arms are attached which have their remote ends connected to the lower axes of the pairs of pivoting arms. These jacks provide in return torque for a weight placed on a supporting table. This is mounted to pivot about the horizontal axis on the frame. A bellows enclose the operating parts.

Description

La présente invention a pour objet un support d'objet dont la hauteur est variable par simple déplacement vertical et qui reste la hauteur dans laquelle il a été amené. The present invention relates to an object support whose height is variable by simple vertical displacement and which remains the height into which it has been brought.

Le support selon l'invention est caractérisé en ce qu'il comprend une embase, un plateau de support relié à l'embase par au moins une paire de biellettes croisées qui sont montées pivotantes à frottement l'une par rapport à l'autre et dont l'une des extrémités est montée pivotante par rapport à l'embase ou au plateau alors que son autre extrémité est montée mobile horizontalement respectivement par rapport au plateau ou à l'embase, et des moyens élastiques exerçant sur l'axe de l'une des biellettes un couple de rappel tendant à amener le support dans sa position haute. The support according to the invention is characterized in that it comprises a base, a support plate connected to the base by at least one pair of crossed rods which are pivotally mounted with friction with respect to each other and one end of which is pivotally mounted relative to the base or the plate while the other end is mounted to move horizontally respectively relative to the plate or the base, and elastic means acting on the axis of the one of the links a return torque tending to bring the support in its high position.

Lorsqu'un objet est placé sur le plateau de support, son poids tend à faire descendre le plateau, à l'encontre du couple de rappel, qui varie suivant la hauteur du plateau. I1 est facile de déterminer le couple de rappel de façon que le plateau tende à prendre une position intermédiaire entre sa position haute et sa position basse. La position stable du plateau est cette position intermédiaire. Mais, lorsque le plateau est déplacé depuis cette position intermédiaire, dans un sens ou dans l'autre, le poids de l'objet ou les moyens élastiques sont insuffisants pour ramener le plateau dans sa position intermédiaire étant donné la force de frottement qui s'oppose au pivotement des deux biellettes l'une par rapport à l'autre. Le plateau reste ainsi à lalauteur à laquelle il a été amené. When an object is placed on the support plate, its weight tends to cause the plate to descend, against the return torque, which varies according to the height of the plate. It is easy to determine the return torque so that the plate tends to assume an intermediate position between its high position and its low position. The stable position of the plate is this intermediate position. But, when the plate is moved from this intermediate position, in one direction or the other, the weight of the object or the elastic means are insufficient to return the plate to its intermediate position given the friction force which s' opposes the pivoting of the two rods relative to each other. The plate thus remains with the author to whom it was brought.

Dans un mode de réalisation avantageux de l'invention, les deux biellettes sont reliées à un premier élément qui est monté pivotant à frottement par rapport au plateau, autour d'un axe horizontal, et à un second élément qui est monté pivotant par rapport à l'embase autour d'un axe vertical. I1 est ainsi possible de régler non seulement la hauteur du plateau de support, mais également son inclinaison et son orientation. In an advantageous embodiment of the invention, the two links are connected to a first element which is pivotally mounted with friction relative to the plate, about a horizontal axis, and to a second element which is pivotally mounted relative to the base around a vertical axis. It is thus possible to adjust not only the height of the support plate, but also its inclination and its orientation.

Pour permettre un réglage facile du couple de rappel, les moyens élastiques sont avantageusement reliés audit axe des biellettes par un élément de longueur réglable. Cet élément peut être constitué par deux plaquettes dont l'une est solidaire de l'axe et porte une lumière sensiblement radiale, alors que l'autre est mobile librement sur cet axe et porte une lumière non radiale, et qui peu vent être fixées l'une par rapport à l'autre dans la position angulaire désirée, les moyens élastiques étant reliés à un axe traversant simultanément les lumières des deux plaquettes. Lorsqu'on modifie la position angulaire des deux plaquettes, la distance entre l'axe de biellette et l'axe traversant les lumières varie, ce qui modifie la valeur du couple de rappel exercé par les moyens élastiques et permet de l'adapter au poids de l'objet à supporter. To allow easy adjustment of the return torque, the elastic means are advantageously connected to said axis of the rods by an element of adjustable length. This element may consist of two plates, one of which is integral with the axis and carries a substantially radial lumen, while the other is freely movable on this axis and carries a non-radial lumen, and which can be fixed l relative to each other in the desired angular position, the elastic means being connected to an axis simultaneously passing through the openings of the two plates. When the angular position of the two plates is modified, the distance between the link axis and the axis passing through the openings varies, which modifies the value of the restoring torque exerted by the elastic means and makes it possible to adapt it to the weight of the object to be supported.

Le dispositif selon l'invention convient, en particulier, pour supporter un terminal d'ordinateur. The device according to the invention is suitable, in particular, for supporting a computer terminal.

On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation du support selon l'invention avec référence au dessin annexé dans lequel
La Figure 1 en est une vue en coupe verticale, suivant
I - I de la Figure 2,
La Figure 2 en est une vue en plan.An embodiment of the support according to the invention has been described below, by way of non-limiting example, with reference to the appended drawing in which
Figure 1 is a vertical sectional view, along
I - I of Figure 2,
Figure 2 is a plan view.

Tel qu'il est représenté au dessin, le support selon l'invention comprend une embase 1 sur laquelle une cuvette rectangulaire 2 est montée pivotante autour d'un axe vertical 3. Un cadre 4 est relié à la cuvette 2 par deux paires de biellettes 5a et 5b disposées dans des plans verticaux. Les deux biellettes d'une même paire sont reliées l'une à l'autre par un pivot 6. L'extrémité supérieure de la biellette Sa et articulée en 7a sur le cadre 4 alors que son extrémité inférieure porte un axe Sa sur lequel est monté un galet 9a engagé dans une glissière 10a fixée à la cuvette 2; de manière correspondante, l'extrémité supérieure de la biellette 5b porte un axe 8b sur lequel est monté un galet 9b engagé dans une glissière lOb fixée au cadre 4 alors que son extrémité inférieure est solidaire d'un axe 7b monté pivotant dans la cuvette 2.Les deux biellettes 5b sont solidaires du meme axe 7b et les pivots 6 sont relativement serrés de sorte qu'il faut un certain effort pour faire pivoter l'urepar rapport a l'autre les deux biellettes 5a et 5b d'une même paire. As shown in the drawing, the support according to the invention comprises a base 1 on which a rectangular bowl 2 is pivotally mounted about a vertical axis 3. A frame 4 is connected to the bowl 2 by two pairs of rods 5a and 5b arranged in vertical planes. The two rods of the same pair are connected to each other by a pivot 6. The upper end of the rod Sa and articulated in 7a on the frame 4 while its lower end carries an axis Sa on which is mounted a roller 9a engaged in a slide 10a fixed to the bowl 2; correspondingly, the upper end of the link 5b carries an axis 8b on which is mounted a roller 9b engaged in a slide lOb fixed to the frame 4 while its lower end is secured to an axis 7b pivotally mounted in the bowl 2 .The two links 5b are integral with the same axis 7b and the pivots 6 are relatively tight so that it takes some effort to rotate the urea relative to the other the two links 5a and 5b of the same pair.

Sur l'axe 7b sont montées pivotantes deux biellettes 11 reliées l'une à l'autre par un axe 12. Le pivotement vers le bas de ces biellettes est limité par des vis réglables 23 représentées uniquement à la Figure 1 et venant en butée contre le fond de la cuvette 2. Deux vérins à gaz 13 travaillant à la compression sont articulés sur l'axe 12 et la tige de piston 14 de chacun d'eux est reliée à. l'axe 7b par l'intermédiaire d'une plaquette 15a qui est montée pivotante sur cet axe et d'une plaquette 15b qui est fixée sur ledit axe. Les deux plaquettes sont reliées l'une à l'autre pa: un boulon 16 qui traverse un trou de la plaquette 14b et une lumière 17 de la plaquette 14a, qui est centrée sur l'axe 7b.La tige de piston 14 porte, à son extrémité, un axe 18 qui traverse une lumière non radiale 19a de la plaquette 15a et une lumière radiale 19b de la plaquette 15b. On the axis 7b are pivotally mounted two rods 11 connected to each other by an axis 12. The downward pivoting of these rods is limited by adjustable screws 23 shown only in Figure 1 and abutting against the bottom of the bowl 2. Two gas cylinders 13 working under compression are articulated on the axis 12 and the piston rod 14 of each of them is connected to. the axis 7b by means of a plate 15a which is pivotally mounted on this axis and of a plate 15b which is fixed on said axis. The two plates are connected to each other pa: a bolt 16 which passes through a hole in the plate 14b and a slot 17 in the plate 14a, which is centered on the axis 7b. The piston rod 14 carries, at its end, an axis 18 which passes through a non-radial lumen 19a of the wafer 15a and a radial lumen 19b of the wafer 15b.

Un support 20 est monté pivotant à frottement sur le cadra 4 par l'intermédiaire de deux pivots horizontaux coaxiaux 21 et un soufflet 22 entoure le mécanisme en reliant l'un à l'autre le support 20 et la cuvette 2. A support 20 is pivotally mounted on friction on the cadra 4 by means of two horizontal coaxial pivots 21 and a bellows 22 surrounds the mechanism by connecting the support 20 and the bowl 2 to each other.

On voit de la description qui précède que le plateau de support 20 peut pivoter autour d'un axe horizontal par rapport à l'ensemble formé par le cadre 4 de la cuvette 2, qui peut lui-meme pivoter autour d'un axe vertical par rapport à 1'embase 1. On peut ainsi régler l'inclinaison et l'orientation d'un objet placé sur le plateau 20. It can be seen from the above description that the support plate 20 can pivot around a horizontal axis relative to the assembly formed by the frame 4 of the bowl 2, which can itself pivot around a vertical axis by relative to the base 1. It is thus possible to adjust the inclination and the orientation of an object placed on the plate 20.

La distance entre le cadre 4 et la cuvette 2 peut être modifiée, les galets 9a et 9b se déplaçant respectivement dans les glissières lOa et lOb. Quand aucun objet n'est placé sur le plateau les vérins 13 tendent à faire pivoter l'axe 7b dans le sens des aiguilles d'une montre à la Figure 1, donc à amener le plateau de support 20 dans sa position haute. Mais, quand un objet est placé sur le plateau, son poids s'oppose au couple exercé par le vérin. C couple dépend de la distance entre les axes du pivot 7b et de la tige 18, ainsi que de l'angle o( que fàit avec l'axe du vérin la droite joignant ces deux axes.En modifiant la position relative de plaquettes 15a et 15b, après avoir desserré le boulon 16, on peut régler la distance entre les dits axes de façon que, lorsque le plateau 20 est à mi-hauteur, le couple exercé par les vérins 13 contre-balance exactement le poids du plateau et de l'objet qu'il supporte. Lorsque le plateau est à une hauteur différente, le vérin 13 ou le poids de ce plateau tendent à ramener ce dernier dans sa p sition médiane. Mais la variation de couple est faible, ainsi par exemple, si l'angle i varie de 60C lorsque le plateau est en position haute, a 800 lorsqu'il est en position basse, le couple exercé par le vérin varie d'environ.6 % par rapport à sableur de réglage. The distance between the frame 4 and the bowl 2 can be modified, the rollers 9a and 9b moving respectively in the slides lOa and lOb. When no object is placed on the plate, the jacks 13 tend to pivot the axis 7b clockwise in FIG. 1, therefore bringing the support plate 20 into its high position. But, when an object is placed on the tray, its weight opposes the torque exerted by the jack. C torque depends on the distance between the axes of the pivot 7b and of the rod 18, as well as on the angle o (which is made with the axis of the jack the straight line joining these two axes. By modifying the relative position of plates 15a and 15b, after having loosened the bolt 16, the distance between the said axes can be adjusted so that, when the plate 20 is at mid-height, the torque exerted by the jacks 13 exactly counterbalances the weight of the plate and the When the plate is at a different height, the jack 13 or the weight of this plate tends to bring the latter back into its median position, but the variation in torque is small, for example if angle i varies from 60C when the plate is in the high position, to 800 when it is in the low position, the torque exerted by the jack varies by approximately 6% compared to the adjustment sandblaster.

Compte tenu du frottement du mécanisme, notamment aux pivots 6, oett variation de couple est insuffisante pour permettre un déplacement du plateau 20 et de sa chargé. Il en résulte que, lorsqu'on a déplacé le plateau 20 pour l'amener à la hauteur désirée, il reste à la hauteur à laquelle on l'a mis.Given the friction of the mechanism, in particular to the pivots 6, the variation in torque is insufficient to allow movement of the plate 20 and of its load. As a result, when the plate 20 has been moved to bring it to the desired height, it remains at the height at which it has been placed.

On voit ainsi que le plateau 20 est réglable non seulement en inclinaison, et en orientation, mais aussi en hauteur et qdil reste dans la position dans laquelle il a été amené. It can thus be seen that the plate 20 is adjustable not only in inclination and in orientation, but also in height and qdil remains in the position in which it has been brought.

I1 va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et repré senté, mais en couvre, au contraire, toutes les variantes.  It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
