ABSTRACT:
A hinge assembly includes a housing (1) encasing a spring (2), a cam follower (3), a cam member (4) and a washer (5) therein. The cam follower has a shaft (31), and a pair of tabs (32) perpendicularly formed on the shaft. The spring is coiled over the shaft, and is compressively engaged in the housing. The tabs of the cam follower slide in grooves (13) of the housing. The cam member includes a cam portion (43) and a connector (41). The cam portion forms a pair of peaks (46) and a pair of valleys (44), being engaged with the tabs of the cam follower. The connector extends outside of the housing. The washer is rotatably inserted over the connector, and is fitted in the housing for fixing the hinge components in the housing.
