Patent ID: 7145107

Claim:
A adjustment interface for adjusting a controller that controls the temperature of a heating device comprising: a controller cover panel having a rotatable controller adjustment member having an end portion extending through an opening of the controller cover panel beyond an exterior surface of said controller cover panel, wherein said rotatable controller adjustment member is operable to adjust a controller when said rotatable controller adjustment member is rotated; a ring member mounted to axially extend beyond and away from the exterior surface of said controller cover panel in substantially the same direction as the extension of the rotatable controller adjustment member, wherein the ring member has projections radially extending from an exterior perimeter of the ring member; and a control member operatively connected to said rotatable controller adjustment member beyond the axial extension of the ring member and said control member operable to effect rotation of the rotatable controller adjustment member when said control member is grasped and turned and said control member having a deflection pin extending therefrom having sufficient length and orientation to crossingly engage the projections extending from the exterior perimeter of the ring member such that the deflection pin resistively engages the projections and flexes to travel radially over and disengaging the projections when the control member is turned with sufficient torque.
