| 摘要 |
The invention concerns a treatment bed adjustable in height having a stand (8), whereof the upper frame (39) and the lower frame (41) are mutually connected through four pairs of hinged levers (42, 43). Said pairs of hinged levers (42, 43) are mutually connected, on either side of the bed, through horizontal (48) and oblique (50) linking spacers. The horizontal linking spacers (48) connect the hinged levers at the articulation while the oblique linking spacers (50) connect a lower lever arm (45) to an upper lever arm (44). The motor (51) for lifting and lowering the upper frame (39) relative to the lower frame (41), extends directly between the two frames, such that the hinged levers with their linking spacers act like a parallel guiding, exclusively activated by hinged articulations, not requiring slides.
