Abstract (en)
[origin: EP0244030A1] A hand-operated releasing and displacing apparatus for a staircase lift or similar transport apparatus, comprising a carrier portion movable along a rail by means of a wheel (4) driven by an electric motor (1) and a reduction gearbox (2). In the event of motor standstill or power failure, a brake (7) is automatically actuated. The apparatus comprises a drive means in the form of a spindle (12) mounted for rotation and being slidable longitudinally against the action of a spring (16) to a hand-operation position, and being adapted to be coupled on the one hand to the wheel drive mechanism and on the other hand to an actuation member (10). Said drive means, upon longitudinal sliding movement to the operable hand-operation position, actuates a current break contact (17, 18) and a mechanical brake releasing device (8). According to the invention, when the drive spindle (12) and the wheel drive mechanism are coupled, the intermediate means have a self-braking effect, the drive spindle (12) is retained automatically in its coupled position and the mechanical brake releasing device (8) is automatically retained in its releasing position.
