ABSTRACT:
An elevator car includes a hold closed feature for an elevator car door. The hold closed feature maintains the elevator car door in a hold closed position when the elevator car is not at a landing or is "parked" at a landing. The hold closed feature includes a profiled ramp disposed on the elevator car and a roller disposed on the elevator car door. The roller engages the profiled ramp during the hold closed position of the elevator car until a certain predetermined force is exerted for the roller to disengage from the profiled ramp.
