Abstract
A mobile invalid hoist comprises a non-rectilinear lifting arm pivotably connected about first horizontal axis to the upper end of mast, a housing pivotably connected about second horizontal axis to one end of the lifting arm and supporting a vertical bearing, a sling hanger support pivotably supported about a vertical or substantially vertical axis by the bearing, and a sling hanger pivotably supported about a third horizontal axis by the sling hanger support. A flexible elongate element is connected between the mast and housing, and is guided through the lifting arm to effectively form with the lifting arm a parallelogram linkage. Thus, as the lifting arm pivots, the housing pivots in relation to the lifting arm and the bearing is kept vertical or substantially vertical.
