Definitions

  • Figure 3a is a longitudinal section of the telescopic lifter of figure 2, taken along the cutting plane IIIA-IIIA;
  • Said kinematic chains are diagrammatically illustrated in figure 5 where they are developed on a plane and generally indicated with C. They comprise:
  • the first kinematic chain C1 consists of a first screw 10b connected to the first gearwheel 15.
  • telescopic lifters consisting of more than four mobile tubular elements.
  • Modifications can also be brought to the telescopic lifter of the invention, for example consisting of a different geometry of the rods that instead of being a prismatic section can have a circular section with longitudinal grooves or they can be replaced by grooved rods.

Abstract

L'invention concerne un châssis télescopique multi-étages (1) qui comprend: un élément tubulaire fixe (2) fermé à une extrémité par une bride (3); et un certain nombre d'éléments tubulaires mobiles (4, 6, 8), chacun étant fermé à une extrémité par une bride respective (5, 7, 9) et étant monté coaxial les uns à l'intérieur des autres et à l'intérieur dudit élément tubulaire fixe (2). Des moyens de type vis (10, 11, 12) sont reliés à chacune des brides (5, 7, 9) desdits éléments tubulaires mobiles (4, 6, 8), et appartiennent à une chaîne cinématique correspondante (C1, C2, C3) raccordée à une unité à moteur (13), ces vis permettant d'extraire simultanément et de manière télescopique chaque élément tubulaire mobile (4, 6, 8) dudit élément tubulaire d'appariement qui le contient.
