Abstract
A springless adjustable bread guard for a heating appliance requires no springs for returning the guard to a desired position. The heating appliance includes a fixed structure relative to the bread guard, and the bread guard includes a resilient bread guard arm having a longitudinal axis and at least one cross member. Each cross member is attached to the bread guard arm spaced apart from a first end of the cross member and at a point along the longitudinal axis of the bread guard arm. The bread guard arm is attached to the fixed structure to rotate about the longitudinal axis. The bread guard operates responsive to a force applied to the arm to rotate a first direction about the longitudinal axis so that one of the cross members contacts a portion of the fixed structure and thereby applies a force to the cross member that causes the arm to bow placing the bread guard in an inward position. The bread guard operates when the applied force is removed to rotate a second direction about the longitudinal axis to an outward position responsive solely to a return force generated by the bowed bread guard arm.
