DESCRIPTION:
BRIEF SUMMARY
This invention relates to a device for lifting invalid patients.
According to one aspect of the present invention there is provided an invalid lifting device comprising two support members each having at least one vertical or substantially vertical leg and a transverse arm at or adjacent to the upper end of the leg, the two transverse arms being pivotable relative to one another about a vertical or substantially vertical axis so that the two support members can be displaced angularly relative to one another, and a hoist supported by one of the support members.
Preferably, power operated means are provided for pivoting the two transverse arms relative to one another. In this case, the power operated means may comprise an electric motor supported with respect to one of the transverse arms and drivingly connected to the other transverse arm, such as through gears.
Preferably, the hoist comprises a power operated winch, a flexible elongate element which can be extended and retracted by the winch and a sling support connected to the free end of the flexible elongate element. In this case, the flexible elongate element preferably depends from one of the transverse arms at or adjacent to the pivot axis of the transverse arms. The winch may be supported by said at least one leg of one of the support members and the flexible elongate element may be guided to a position in which it depends from one of the transverse arms at or adjacent to the pivot axis of the transverse arms.
In one embodiment, each support member has two spaced apart vertical or substantially vertical legs connected together at or adjacent to their upper ends by a transverse arm in the form of a cross arm. In this case, the cross arms are preferably pivotably connected together midway or substantially midway between their ends. The lower ends of the legs are, preferably, provided with wheels or castors. In this case, the legs of one of the support members may be provided with braking means which may take the form of extendible feet which can be extended to engage the floor.
Preferably, the two support members of said one embodiment are angularly displaceable relative to one another between a position in which the transverse arms extend perpendicularly or substantially perpendicularly to one another and a position in which the transverse arms extend at an angle no greater than 20.degree. to one another.
In another embodiment, each support member has only one vertical or substantially vertical leg and stabilizing means are provided at the lower end of each leg to prevent the lifting device from falling over. The stabilising means may be in the form of elongate chassis members which may be kept parallel or substantially parallel, such as by drive motors, as the support members are pivoted relative to one another. Each chassis member may have two wheels or castors and may be provided with braking means.
Preferably, the two support members of said another embodiment are angularly displaceable relative to one another between a position in which the transverse arms extend at an angle of at least 90.degree. to one another (and preferably at a greater angle, typically about 105.degree.) and a position in which the transverse arms extend at an angle no greater than 20.degree. to one another.
Preferably, at least one of the legs is provided with a handle whereby an operator can move the hoist along the floor.
Preferably, the sling support comprises a sling hanger and a sling hanger support, the sling hanger support being connected to the free end of the flexible elongate element and the sling hanger being connected to the sling hanger support for pivotable movement about a horizontal or substantially horizontal axis and having two spaced sling attachment points on one side of the horizontal axis and at least one sling attachment point on the other side of the horizontal axis.
According to another aspect of the invention there is provided an invalid lifting device comprising two support members movable relative to one another between a first position in which
