ABSTRACT:
An elevator hoistway door is coupled to an elevator car door so as to be opened and closed in unison therewith by means of a pair of shoes which are mounted on the elevator door and have cammed surfaces that allow the shoes to be spread so as to be wedged within the walls of a channel that is mounted on the hoistway door. The wedging action is caused by a solenoid actuator and the shoes are returned by means of a spring to a rest position in which they have adequate clearance within channels of all of the hoistway doors which the elevator may pass. Advance door opening and releveling is accommodated by means of rollers or sliding contact.
