Abstract

La présente invention concerne un dispositif conçu pour transporter une charge entre une surface de représentation et une surface inférieure s'étendant sous celle-ci. Le dispositif comprend une surface de plate-forme qui reçoit la charge et dont les déplacements entre la surface de représentation et la surface inférieure s'effectuent le long d'éléments de délimitation latéraux, lesquels éléments de délimitation s'étendent entre un bâti supérieur pouvant être fixé dans une ouverture présente dans la surface de représentation et un bâti inférieur reposant sur la surface inférieure. L'invention est caractérisée en ce que les éléments de délimitation latéraux sont constitués d'une matière souple, et au moins deux des voies formées par cette matière, qui s'étendent l'une par rapport à l'autre de façon plane et parallèle, constituent une cage dans laquelle sont guidés les déplacements de la surface de plate-forme.
