Patent ID: 7681283

Claim:
A hinge assembly comprising: a fixed member; a movable member connected to said fixed member such that said movable member is rotatable about a rotation axis and movable toward and away from said fixed member along said rotation axis; and biasing means biasing said movable member toward said fixed member, one of opposing surfaces of said fixed member and said movable member facing each other having an abutment member disposed therein, said abutment member being abutted against the other of said opposing surfaces by said biasing means, said the other of said opposing surfaces having a first cam portion disposed therein, said first cam portion converting a biasing force of said biasing means into a first rotational biasing force by being abutted against said abutment member, said movable member being rotationally biased in a first circumferential direction by said first rotational biasing force via said abutment member, characterized in that said one of said opposing surfaces has a receiving recess formed therein; that said abutment member is received in said receiving recess such that said abutment member is movable in a circumferential direction about said rotation axis within a predetermined range; and that said receiving recess has a first hitting portion disposed in one end portion thereof in said first circumferential direction, said first hitting portion defining one of limit points of a movable range of said abutment member and generating a clicking sound by being abutted against said abutment member moved by said first rotational biasing force.
