The invention relates to a device (1) having a base plate (2) and a support (5) for the height adjustment of an assembly group without tools, particularly of a kitchen module in an airplane. According to the invention two wedge bodies (3, 4) moving in opposite directions are disposed between the base plate (2) and the support (5) in a horizontally displaceable manner, wherein a lifting or lowering of the support (5) occurs for the height adjustment due to the manual displacement of the two wedge bodies (3, 4) placed opposite one another - when the latch levers (26, 27) are lifted - in the adjustment position. The connection of the assembly group to the support (5) occurs, for example, by means of a conventional screw connection through the attachment bore (44) in the support (5). Any maladjustment of the device (1) due to uncontrolled displacement movements of the wedge bodies (3, 4) is prevented by the spring-loaded latch levers (26, 27) that are accommodated in the wedge body in a deviating manner. The latch levers (26, 27) are further secured in position by a stopper (39, 40). The device (1) according to the invention enables a simple, quick height adjustment of an assembly group disposed thereon by a user without any tools, thus reducing the installation expense of pre-fabricated assembly groups, or modules, in airplanes.

L'invention concerne un dispositif (1) avec un socle (2) et un support (5) pour ajuster sans outil la hauteur d'un sous-ensemble, notamment d'un module de cuisine dans un avion. Selon l'invention, deux corps cunéiformes opposés (3, 4) sont disposés à translation horizontale entre le socle (2) et le support (5), le déplacement manuel en sens contraires des deux corps cunéiformes (3, 4) - tandis que des leviers d'encliquetage (26, 27) sont relevés - dans la = position d'ajustement = engendrant un relevage ou un abaissement du support (5), pour le réglage en hauteur. L'assemblage du sous-ensemble avec le support (5) s'effectue par exemple au moyen d'un assemblage vissé classique par le perçage de fixation (44) dans le support (5). Un désajustement du dispositif (1) suite à des mouvements de translation incontrôlés des corps cunéiformes (3, 4) est empêché par les leviers d'encliquetage (26, 27) sollicités par ressort, reçus à pivotement dans les corps cunéiformes. Les leviers d'encliquetage (26, 27) sont en outre chacun fixés en position par un tampon (39, 40). Le dispositif (1) selon l'invention permet à un utilisateur un ajustement en hauteur simple, rapide et surtout sans outil d'un sous-ensemble disposé sur ce dispositif, de sorte que l'effort de montage de sous-ensembles préfabriqués ou encore de modules dans des avions est considérablement réduit.
