These assure minimal displacement in the longitudinal direction of the part by the feet when the bed or table (M) moves from vertical to horizontal position. The device may comprise four points to ensure good stability. It may comprise a pair of connecting rods articulated at two symmetrical fixed points of a fixed mounting (R4).

Description

La présente invention concerne un dispositif permettant le basculement d'un lit ou d'une table d'examens, par un moteur, de la position verticale à la position horizontale et vice versa, dans le plan sagittal.The present invention relates to a device allowing the tilting of a bed or examination table, by a motor, from the position vertical to the horizontal position and vice versa, in the sagittal plane.

Les lits ou les tables d'examens basculants généralement existants ont un axe de basculement fixe et une partie fixe dont l'encombrement au sol dépasse la projection de la partie mobile en position horizontale.Typically existing tilting examination beds or tables have a fixed tilt axis and a fixed part whose footprint exceeds the projection of the moving part in a horizontal position.

Le dispositif selon l'invention permet de faire passer un lit ou une table d'examens de la position verticale à la position horizontale et vice versa de telle manière qu'aucune pièce mécanique ne se trouve au-dessus et (ou) en-dehors du lit ou de la table d'examens évitant ainsi tout risque d'interposition d'un membre.The device according to the invention makes it possible to pass a bed or a examination table from vertical to horizontal position and vice versa from such that no mechanical parts are above and / or outside of the bed or the examination table thus avoiding any risk of interposition of a member.

Le dispositif selon l'invention permet une bonne stabilité du lit ou de la table d'examens mobile par quatre points d'appui.The device according to the invention allows good stability of the bed or the mobile examination table by four support points.

Selon des modes particuliers de réalisation :

  • un moto-réducteur peut permettre la mobilisation d'un plan support de lit ou de table d'examens.
According to particular embodiments:
  • four parallel connecting rods two by two, articulated on a fixed frame can impose the displacement;
