Abstract
A hinge assembly (100) includes a shaft (10), a cam (20), and an elastic member (30). The shaft is in the form of a rod and provided with a projection (16). The cam includes a body (21) and a center cavity (23). The body of the cam defines a cam face (22) at one end thereof, and the projection of the shaft is engaged with the cam face. The shaft travels through the center cavity of the cam. One end of the elastic member biases relative to a distal end portion of the shaft, and an opposite end of the elastic member abuts an end of the cam opposite the cam face.
