An expanding and retracting belt buckle composed of a journal assembly connected to a spring disposed in the main body of the buckle. The main body contains a locking assembly to attach one end of the belt and also contains a pair of spaced parallel longitudinal tracks. The journal assembly has a cylindrical roller at each end which travels along the track in response to the urging of the spring. An outer plate is attached to the journal assembly for allowing longitudinal movement of the plate against the force of the spring. The opposite end of the plate has a projection for insertion into the other end of the belt. |
