Abstract

Device making it possible to obtain different heights for table tops as well as a clearance in high position for use as a desk, a table for meals, a work table, a work bench, etc. It consists of a double rod assembly 2 mounted on axles 3 making it possible to raise the table top 5 to an upper height by means of a pneumatic or compressable gas system 4 available commercially. The table top in its high position gives access to a storage container 1. Closure in a low position is obtained by locking the table top with the lock. The device according to the invention is particularly intended to turn low tables into high tables and desks.

Description

La présente invention concerne un dispositif permetd'élever un plateau de table et de le déporter. The present invention relates to a device for lifting a table top and deporting it.

Ce qui permet un dégagement sous ce plateau et trans foneune table basse en bureau, table repas ou autres services. This allows clearance under this tray and transits a coffee table into an office, dining table or other services.

I1 existe actuellement des tables basses à hauteurs variables à élévation verticale dont le fonctionnement est est au à des pressions pneumatiques ou mécaniques complexes. I1 currently exist low tables with variable heights with vertical elevation whose operation is due to complex pneumatic or mechanical pressures.

Le dispositif selon l'invention a pour but de faire monter le plateau et d'en dégager le dessous, ce qui permet à l'utilisateur, dans la position assise, de placer aisément ses jambes sous le plateau. The purpose of the device according to the invention is to raise the tray and release the underside thereof, which allows the user, in the seated position, to easily place his legs under the tray.

Selon une forme de réalisation simple, une table basse de hauteur 0,40 m, par exemple, comportant 4 pieds et dont le plateau est muni de ce système à double bras pivotants, permetren soulevent manuellement de surélever et déporter en un seul mouvment ce plateau pour des utilisations multiples (déjeuner, lecture, machine à écrire, courrier, bureau, etc...). According to a simple embodiment, a 0.40 m high coffee table, for example, comprising 4 feet and the tray of which is provided with this system with double swivel arms, allows the manual lifting and lifting of this tray in one movement for multiple uses (lunch, reading, typewriter, mail, office, etc ...).

La figure 1 représente en perspective une table dont le plateau est dessiné en pointillés en position basse et en trait plein en position haute. Figure 1 shows in perspective a table whose tray is drawn in dotted lines in the low position and in solid lines in the high position.

La figure 2 représente cette même table dont le plateau est en position haute. FIG. 2 represents this same table, the plate of which is in the high position.

Le système représenté sur les figures 1 et 2 comporte un bati (1) comprenant un cadre en bois avec 4 piètements d'environ 0,40 m, similaire au chassis d'une table basse normale, à l'intérieur du cadre sont fixéex 2 tringleries (2) montées chacune sur 2 axes (3) solidaires du chassis et 2 axes supérieurs (4) fixés sur le plateau (5). The system shown in Figures 1 and 2 includes a frame (1) comprising a wooden frame with 4 legs of about 0.40 m, similar to the frame of a normal coffee table, inside the frame are fixed x 2 linkages (2) each mounted on 2 axes (3) integral with the chassis and 2 upper axes (4) fixed on the plate (5).

La figure 3 représente la fixation de l'ensemble de l'axe, par l'intermédiaire d'une équerre (6) assemblée par vis sur le dessous du plateau. Figure 3 shows the attachment of the entire axis, via a bracket (6) assembled by screws on the underside of the plate.

La transformation pour surélever le plateau consiste à prendre à 2 mains (une de chaque coté) le plateau (5) dans le sens de l'axe du piètement, en soulevant le plateau les axes et la tringlerie vont décrire un arc de cercle et lorsque l'ensemble aura dépassé la verticale, le propre poid du plateau fera légèrement redescendre le double système pantographe jusqu'à la butée (7). Pour redescendre
Le pantographe, il suffit d'effectuer la manoeuvre inverse le plateau venant reposer sur le bati (1).The transformation to raise the plate consists in taking with 2 hands (one on each side) the plate (5) in the direction of the axis of the base, by lifting the plate the axes and the linkage will describe an arc of a circle and when the assembly will have exceeded the vertical, the own weight of the plate will slightly lower the double pantograph system until the stop (7). To descend
The pantograph, it suffices to reverse the plate coming to rest on the frame (1).

Selon une variante figure 4 et 5 le soele est constitué d'un caisson (1) dont l'intérieur est aménagé, par exemple, de porte documents (9) et la partie (10) en ranrangement pour les bouteilles, lorsque le plateau (5) est en position de table basse il peut être fermé par une serrure (8) et être assisté par un système pneumatique (11) à gaz comprimable. According to a variant in FIGS. 4 and 5, the soele consists of a box (1) the interior of which is arranged, for example, of document holders (9) and the part (10) in storage for the bottles, when the tray ( 5) is in the low table position; it can be closed by a lock (8) and assisted by a pneumatic system (11) with compressible gas.

La réalisation de la transformation est effectuée par l'évolution du paralléllogramme (2) qui dans le mouvement de montée ou de descente du plateau le maintient sur un plan horizontal, ce qui permet de régler la hauteur désirée en changeant la position de la butée (7). The transformation is carried out by the evolution of the parallelogram (2) which in the movement of raising or lowering of the plate maintains it on a horizontal plane, which makes it possible to adjust the desired height by changing the position of the stop ( 7).

Claims

1) Device for raising a table top and deporting it characterized in that it comprises a linkage (2) mounted on axes (3) and allowing, by lifting the plate (5) to give it two heights as well a horizontal offset in the high position in order to obtain a clearance allowing the passage of the legs of the user.

2) Device according to claim 1, characterized in that the rise of the plate (5) allows the opening of a box (Figure 4) forming a storage box (1).

3) Device according to claim 2, characterized in that a lock (8) allows the closure of the box (1) (Figure 5) by the plate.

4) Device according to one of claims 1 to 3 characterized in that the rise of the plate (5) is assisted by a pneumatic system (11) with compressible gas, the extension of the plate being controlled by unlocking using the lock (8).

5) Device according to claims 1 to 4 charac terized in that the rise and offset of the plate (5) are obtained by a double metal parallelogram (2).

6) Device according to claims 1 to 4, characterized in that the rise and the offset of the plate (5) are obtained by a double parallelogram in wood or chipboard panels.

7) Device according to claims 1 to 6 characterized in that the rise and the offset of the plate correspond to the opening of a storage chest.
