ABSTRACT:
The lifting device for use in a bath tub consists of a bottom frame, lying on the ground of a bath tub, and an upper frame which is in parallel to the bottom frame and adjustable in height, and a supporting plate being fixed on the upper frame. Between the bottom frame and the upper frame is arranged a pantograph type frame consisting of two interconnected slewing frames. In order to reach a large lifting height, a Z-shaped lifting hose is sectionally fastened at the slewing frame in such a way that the horizontal hose sections prop against correspondent and adjacent inclined hose sections. By this, in order to reach a large lifting height, not only the variation of length but also the increase of width of the lifting hose are used when supplying the hose with compressed water.
