Abstract:
A door latch operator includes a hand grip actuator lever for retracting one or more latch bolts mounted at a free side edge of a door, such as an entry door for a residence or place of business. The actuator lever is pivotally mounted at an inboard side of a manually grasped handle for grasping and squeezing with the fingers against the door handle to operate a torque converter or cam module for indexing a rotary cam through a rotary step. The rotary cam is coupled to a latch bolt retractor mechanism for retracting the latch bolt or bolts and thereby permit opening of the door. In a preferred form, the latch bolt retractor mechanism operates multiple latch bolts mounted along the free side edge of the door.
