Abstract
A rail mounted patient lift comprises a ceiling mounted rail, a carriage mounted for displacement along said rail, power operated drive means for displacing the carriage along the rail, a sling hanger secured to a flexible elongate support element, power operated lifting means for extending and retracting the elongate support element relative to the carriage, a manually operable controller and control circuit means for moving said carriage to a selected one of a plurality of different positions along the rail in response to a first command signal from the controller.
Claims12
A rail mounted patient lift comprising:
- a ceiling mounted rail;
- a carriage mounted for displacement along said rail;
- power operated drive means for displacing the carriage along the rail;
- a sling hanger secured to a flexible elongate support element;
- power,operated lifting means for extending and retracting the elongate support element relative to the carriage;
- a manually operable controller;
- control circuit means for moving said carriage to a selected one of a plurality of different positions along the rail in response to a first command signal from the controller;
- and
- a load detector for detecting if a load is present on the sling hanger, the power operated lifting means being operable by the control circuit means to raise the sling hanger if in a down position with no load thereon when receiving a command signal from the controller to move the carriage along the rail.
A rail mounted patient lift comprising a ceiling-mounted rail, a carriage mounted for displacement along said rail, motorised drive means for displacing said carriage, a sling hanger secured to a retractable cable and vertically displaceable from said carriage by a lift motor, control circuit means for receiving command signals from a hand-operated controller, a load detector to detect if a load is present on said sling hanger, said control circuit operating said life motor to retract said sling hanger if in a down position with no load thereon when receiving a command signal from said control circuit to freely move said carriage on said rail from a homing position, said control circuit having a programmable memory with a homing function to automatically return said carriage to said homing position when receiving a homing signal, and means to arrest said freely moving carriage at a desired position along said rail.
A rail mounted patient lift comprising:
- a ceiling mounted rail;
- a carriage mounted for displacement along said rail;
- power operated drive means for displacing the carriage along the rail;
- a sling hanger secured to a flexible elongate support element;
- power operated lifting means for extending and retracting the elongate support element relative to the carriage;
- a manually operable controller;
- control circuit means for moving said carriage to a selected one of a plurality of different positions along the rail in response to a first command signal from the controller;
- a plurality of location identifying means mounted at predetermined positions along the track and detector means mounted on the carriage for detecting the presence of the location identifying means;
- and
- audible sound generator means for emitting a sound when said detector means detects any of said location identifying means to signal the movement of said carriage and its location along said rail.
