ABSTRACT:
A control knob assembly for a cooking appliance includes a control knob and a track body disposed in the control knob. A ring-shaped bezel having a plurality of inwardly projecting guide followers is mounted to the control knob, whereby the guide followers ride in tracks disposed within a top surface of the track body. The control knob is slidable over the track body, and is alternatively locatable in extended and retracted positions. When the control knob is located in a retracted position, the guide followers are releasably secured in notches contained in the tracks. When depressed, the guide followers are disengaged from the notches, permitting the control knob to move to an extended, operating position. In the operating position, the user depresses the control knob, thereby engaging a second plurality of notches which permit operation of a two-step gas valve by sequentially depressing and rotating the control knob.
