摘要： A counterbalance hinge assembly includes a cam and compression device that counterbalances a weight of a door or a ramp. The compression device biases against a rotation of the door or ramp. The downward movement of the door or ramp drives cam followers in angled slots or cam surfaces of the cam. The angled slots or cam surfaces include varying angles of incline to correspond to varying torque forces of the door or ramp during the opening or closing movement of the door or ramp.
