Abstract

A hinge assembly (10) includes a tubular hinge housing (11) encasing a follower member (14), a cam (13) and a spring (12) in an interior space thereof. The follower member has a connector (141), a shaft (143), and a cylindrical portion (142) having a flat surface (1421) and at least one tab (1424) formed on the flat surface. The cam forms at least one peak (1321) and one valley (1322) thereon. The cam and the spring are respectively inserted over the follower member. Wherein the cam is sildably engaged in the hinge housing, and is rotatably and sildably coupled to the shaft of the follower member so that the tab of the follower member is received in the valley of the cam. An insert member (15) is inserted into the interior space of the tubular hinge housing for retaining the follower member therein.
