Abstract

L'invention concerne un dispositif comportant un élément massif et des moyens permettant de soulever puis de relacher ladit élément. L'élément massif comprend une dalle (3) pouvant librement coulisser dans un chassis, et les moyens de levage comportent des moyens d'entrainement par friction (5) d'un coté de la dalle et des moyens applicateurs (6) de l'autre coté de la dalle, ces derniers pouvant etre déplacés entre une position active des soulèvement et une position passive dans laquelle ladite dalle est relachée pour sa chute libre.The invention relates to a device comprising a solid element and means making it possible to lift and then release said element. The solid element comprises a slab (3) which can slide freely in a chassis, and the lifting means comprise friction drive means (5) on one side of the slab and applicator means (6) of the other side of the slab, the latter being able to be moved between an active lifting position and a passive position in which said slab is released for its free fall.
