Abstract: The weight of a pivoted body is counterbalanced by a spring acting on a cam connected to that body to pivot therewith. A band, connected to that spring, attaches to the cam and wraps around the cam. The cam's profile is contoured to produce moment arms of various lengths, through which the force of the spring acts, balancing the variable torque of the weight of the pivoted body.

Abstract: An emergency door closing device that can be installed upon existing doors and hinges to automatically close doors in the response to smoke and fire. The improvements incorporated therein include a hinge cam pivot member that attaches to an existing hinge member of a door and produces a moment force about the existing hinge member allowing a reduced force necessary to pivot the door into a closed position. Further, a novel spring, cam, and lever system is incorporated to activate the moment force to close the door.

Abstract: An apparatus comprises a base plate configured to be coupled to a door, the door configured to be positioned in an open position and a closed position; a closing mechanism coupled to the base plate and configured to be coupled to a hinge of the door and having an unprimed state and a primed state, the closing mechanism configured to be transitioned between the unprimed state and the primed state by a user; wherein in the unprimed state the closing mechanism is decoupled from operation of the door; and in the primed state the closing mechanism is configured to move the door into the closed position responsive to receipt of a signal, and the closing mechanism is configured to allow movement of the door between the open position and the closed position in absence of the signal.

Abstract: A refrigerator includes a cabinet, a door, and a door opening device. The door opening device includes a motor and a pushing member configured to be withdrawn out by the motor to open the door. The pushing member includes a first rack configured to be driven by the motor and to push one of the cabinet or the door, and a second rack configured to be driven by the motor and slidably coupled to the first rack in which the second rack at least partially overlaps with the first rack. The first rack is configured to move relative to the second rack in a first direction to open the door to a first angle, and to move together with the second rack in the first direction to move the door to a second angle greater than the first angle.
