  • Patent number: 6718573
    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.

  • Patent number: 6708622
    Abstract: A rail mounted patient lift comprises a ceiling mountable rail 10, a carriage 16 mounted for displacement along the rail, a flexible elongate support element and power operated lifting means for extending and retracting the support element relative to the carriage. The rail 10 comprises a plurality of rail sections 10a, 10b which in use are suspended from a ceiling with a gap 13 therebetween at a position where the rail 10 is to cross the path of a curtain 14. Each rail section has at least one pivotable flap 19 engageable by the carriage 16 as it moves along the rail. The flap 19 of one of a pair of adjoining rail sections is pivotable by the carriage as it moves in one direction to bridge the gap between the two sections and the flap of the other of the pair of adjoining rail sections is pivotable by the carriage as it moves in an opposite direction to bridge the gap between the two rail sections.

  • Patent number: RE39254
    Abstract: The invalid lifting device comprises a first mast upstanding from a first elongate chassis member and a second mast upstanding from a second elongate chassis member which is parallel or substantially parallel to the first chassis member. The lifting device also comprises a lifting arm supported by and extending between the first and second masts, the lifting arm comprising two parts pivotable relative to one another so that the distance between the masts can be varied. One part is supported by the first mast and the other part is supported by the second mast. Power operated means are provided for moving the two chassis members towards and away from one another. Each part of the lifting arm comprises a parallelogram linkage to maintain the chassis members in parallel or substantially parallel relationship as the two chassis members are moved towards and away from one another.
