Abstract

A door lever assembly having a locked and an unlocked position includes a trim housing and a lever handle rotatably connected to the trim housing. A cam is rotatably connected to the trim housing, and a pin mechanism is movably positionable to connect with the lever handle. A slider is attached for movement in the trim housing in response to rotation of the cam, anda lift arm is connected to the slider. The lift arm is rigidly movable with the slider when the door lever assembly is in its unlocked position and the lever handle is rotated. When the door lever assembly is in its locked position, the lift arm pivots toward the cam to disengage the pin mechanism from its connection between the lever handle and the cam.
