Abstract
A hinge assembly comprising a movable memberand a fixed memberrotatably connected to each other and a coiled spring (not shown) biasing the movable membertoward the fixed member. A receiving recessis formed in an opposing surfaceof the movable memberfacing the fixed member. A spherical bodyis received in the receiving recesssuch that the spherical bodyis movable in a circumferential direction of the movable member. A first cam portionis formed in an opposing surface of the fixed memberfacing the movable member. Rotation of the movable memberin a direction of an arrow causes the cam portionto be abutted against the spherical body. The cam portionconverts a biasing force of the coiled spring into a rotational biasing force. The rotational biasing force causes the spherical bodyto be rapidly abutted against a first hitting portionof the receiving recessand thereby to generate a clicking sound.
