Patent ID: 8434199

Claim:
A knob safety assembly operative to restrict depression of a control knob of a cooking device, the assembly comprising: a bezel assembly comprising: an outer bezel defining a first angled camming surface and having and a rear face; an inner bezel disposed partially inside the outer bezel and rotatably coupled thereto for rotation about a rotational axis; wherein the inner bezel is selectively lockable against rotation with respect to the outer bezel; a blocking plate disposed inside the bezel assembly; wherein the blocking plate has an opening to receive a switch post of a cooking element control knob and has a first ear in sliding abutment with the first camming surface; wherein rotation of the inner bezel with respect to the outer bezel slides the first ear along the first camming surface to effect displacement of the blocking plate along the rotational axis between a raised position in which the blocking plate is further from the rear face to restrict depression of the control knob, to a recessed position in which the blocking plate is closer to the rear face to facilitate depression of the control knob; wherein the inner bezel engages the blocking plate to constrain the blocking plate against displacement along the rotational axis when the inner bezel is rotationally locked with respect to the outer bezel.
