Abstract
An invalid hoist comprising a chassis having a main support member on which a mast is supported and two side members extending forwardly of the main support member. The side members are swivellable by a power operated device between a first position in which they extend from the main support member in parallel or substantially parallel spaced relationship, and a second position in which they diverge as they extend forwardly from the main support member. The power operated device comprises an electrically powered actuator and a linkage arrangement which ensures that the side members are swivelled in opposite angular directions at equal angular rates of displacement by the actuator.
