Abstract

A knob assembly for a gas cooktop may include a knob configured to control a flow of gas from a burner of a cooktop starting at a resting position, the knob defining a hollow interior and having a support cylinder extending vertically through the hollow interior, wherein the support cylinder includes a projection flap protruding therefrom, an inner lock ring arranged at least partially within the hollow interior of the knob and having a chamfered region defining a ring opening adjacent an inclined portion, where the opening is configured to selectively receive the projection flap in response to depression of the knob and where the projection flap slides along the inclined portion in response to subsequent rotation of the knob, the inclined portion imparting frictional resistance on the projection flap to prevent against unintentional rotation of the knob.
