Abstract
A portable phone has a cavity at one end in which a hinge pin is rotatably mounted, with opposite ends of the hinge pin releasably secured to a flip panel rotatable between a closed position extending over part of one face of the phone, and an open position. The hinge pin includes a cam formation, and a biasing spring secured in the cavity has a bearing portion acting against the cam portion to releasably retain the flip panel in its open and closed positions. A cam retainer is mounted in the cavity to extend over the hinge pin and resist bending of the hinge pin out of a straight, axial orientation.
