ABSTRACT:
Sliding door operating means comprises a wall-mounted rack, operating mechanism connected to said door and having a pinion meshing with the rack and means for manually rotating said pinion to move the door between open and closed positions, and an energy-absorbing coupling between the manually actuated means and the pinion for absorbing rotational energy resulting from the inertia of the manually actuated means when the door reaches the end of its travel either to the open or completely closed position.
