ABSTRACT:
A control button assembly for positioning an operating rod to "lock" and "unlock" a vehicle door lock includes a sleeve member and a button member. The button member has a hollow stem portion for threading onto an upper end region of the operating rod. The sleeve member is a tubular part that surrounds the stem of the button member. The sleeve member is mountable on a window sill of a vehicle door structure, with portions of the sleeve member extending through a sill opening to surround the threaded upper end region of the operating rod. The sleeve member has a plurality of integrally formed, resilient fingers that depend from the sill as they extend alongside the stem of the button. The fingers have inwardly turned tip portions that frictionally grip outer surface portions of the stem. The frictional grip of the fingers on the stem acts as a detent to assist in holding the button in its lowermost or "locked" position. When the button member is moved to its uppermost or "unlocked" position, the tip portions move radially inwardly to underlie and obstruct downward movement of the button member from its unlocked position. Inclined cam surfaces are provided on the tip portions to engage the bottom surface of the button stem and to flex the resilient fingers radially outwardly in response to forceful downward movement of the button member from its unlocked position toward its locked position.
