Abstract: The belt or strap clip includes a main body and a clip arm. The main body is adapted to retain, via a button mount, a cellular telephone or other personal electronic device. A plastic leaf spring has a fore end mounted to the main body, a curvaceous mid-section and an elongated leg member. The leg has a proximal pivot member and the distal leg region is disposed in a capture channel in the clip arm. A complementary pivot member in the clip arm coacts with the proximal pivot member such that when the main body pivots with respect to the clip arm, the elongated leg member bows. The method includes capturing the distal end of the spring into the clip arm and permitting the elongated leg to bow inboard during the pivot between the clip body and the clip arm.

Abstract: The clip-mount operates with a button sub-mount system and includes a body defining a locking cavity for the button and a resilient locking tongue therein. The tongue biases the button into a locking position with a cam surface. A movable cam actuator on the body includes another cam surface which coacts with the first cam permitting the tongue to flex or unlock. An enhancement includes both an unlocking cam and a second locking cam structure. The method includes biasing the button to a locking position and moving one cam over another thereby flexing the tongue from a locked to a button release position. The actuator maybe biased outboard or upward via a plastic spring on the actuator-plunger. A plastic leaf spring may be provided between a clip arm and the button clip mount body. A lock or latch may lock on the actuator-plunger.
