Abstract
A door lever assembly includes a lever handle rotatably connected to a trim housing. A pair of guide rods positioned in the trim housing support a stop plate and a movable slider. A cam is operably connected to the lever handle and positioned to rotate in response to rotation of the lever handle, converting its rotational movement to linear movement of the movable slider positioned adjacent to the cam. A lift arm is operably connected to the slider to engage and disengage door latches in response to movement of the slider when the door lever assembly is unlocked. When the door lever assembly is locked, an over-ride spring connected between the slider and the lift arm compresses in response to slider movement, preventing damage to components of the door lever assembly. When the door lever assembly is unlocked, a pivot rotates to control contact between the slider and the stop plate.
