PCT No. PCT/GB95/00606 Sec. 371 Date Feb. 11, 1997 Sec. 102(e) Date Feb. 11, 1997 PCT Filed Mar. 20, 1995 PCT Pub. No. WO95/30400 PCT Pub. Date Nov. 16, 1995The invalid hoist comprises a mobile chassis 10, a lifting column 11 upstanding from the chassis and a lifting arm 12 supported by the lifting column. The chassis comprises a main portion 13 extending transversely of the hoist and two side members 14 which are movable between a first in-use position in which they project forwardly from the main portion, and a second storage position in which they extend parallel or substantially parallel to the lifting column. Side members 14 are also pivotable about a vertical axis, allowing them to spread away from one another at their forward ends. Releasable means 22 may be provided for holding the lifting arm in an operative position and for releasing the lifting arm to allow it to pivot into a storage position alongside the lifting column. Alternatively, an extendible, retractable device may be connected between the lifting arm and the lifting column at positions remote from the pivot axis between the lifting arm and the lifting column so that the lifting arm can be moved between an operative position and a storage position alongside the lifting column. |
