Abstract:
An apparatus that at least assists in maintaining a lever or knob of a lock device in a relatively neutral and static position. The apparatus includes a biasing element that can be constructed from a compliant material that may at least assist in reducing impact forces between interfacing surfaces at least when the lever or knob is returns to the neutral, static position from one or more activated positions. The compliant nature of the damper can further alleviate issues relating to manufacturing tolerances and wear between interfacing surfaces.
