Abstract: In a hinge structure suitable for use in a foldable mobile phone, the initial unfolding action is effected by converting a pushing stroke of an operating member into a rotational movement of the hinge by using a cam/cam follower mechanism. Thereby, an unexpected reaction force resulting from the inertia force acting between the two parts that are to be unfolded relative to each other can be avoided, and a favorable unfolding action without a shock can be achieved. In particular, it may be arranged such that the hinge is normally urged in the unfolding direction while a clutch is kept engaged to retain the hinge in the fully folded state, and that the hinge is resiliently driven in the unfolding direction by pushing the operating member and thereby disengaging the clutch.

The seat is provided with a receiving space in which the pivoting end of the pivoting member and the cam member are pivoted such that the pivoting member is capable of turning on the pivoting end acting as a fulcrum, and that the cam portion of the cam member is pressed by the elastic pressing member so as to regulate the angle at which the seat and the pivoting member are caused to intersect.

Abstract: A closure apparatus for a subsurface pit for servicing an aircraft located beneath an aircraft servicing surface across which aircraft travel is provided with an improved spring biasing arrangement. The system employs separate springs interposed between the hollow body of the pit and the lid so as to urge the pit lid from its horizontal seated position toward a fully raised position. Obstructions are provided for separately intercepting and disengaging the springs from acting against the pit lid as the pit lid is opened through intermediate angular positions between the horizontal seated position and the fully raised position. By sequentially isolating the pit lid from the action of each of the springs, one at a time, the moment of spring force opposing closure of the lid more closely follows the moment of the force of gravity tending to close the lid. This substantially reduces the maximum manual force that is thereby required to overcome gravity in opening the pit lid.

The hinge is characterized by its low profile and low number of parts.

Abstract: A double-pivot door hinge is disclosed that is particularly suited for household appliances such as refrigerators or microwave ovens. The hinge arrangement allows the appliance door to be opened a full 180 degrees from its closed position without coming into contact with a flush mounted wall such as an abutting kitchen cabinet. The hinge has a first pivot pin and a stop arrangement which allows a door to be swung outwardly until a 90-degree position is reached whereby the stop arrangement is engaged. Upon further outward movement, the assembly shifts to a second hinge pin until a 180-degree position is reached. The movement from the 90-degree position to a 180-degree position requires the overcoming of a spring force of the hinge arrangement.

Abstract: A gas spring is provided in an illustrational example between a framework and a trunk cover of a motor vehicle for compensating for the weight of the trunk cover during movement of said trunk cover. The gas spring is hinged to the framework and to the trunk cover. For eliminating the spring force action on the hinge between the trunk cover and the gas spring in the closed position of the trunk cover, the part of the gas spring hinged to the trunk cover is supported on the framework, when the trunk cover is in its closed position. Alternately, the gas spring is locked when the trunk cover is in its closed position.

The cam is of such a configuration that, when the hinge is moved from the open position to the closed position, just before it reaches the closed position, the line of thrust applied by the hairpin spring passes through the pivot axis of the link, but then the spring passes over onto a portion of the cam associated with the second position of the latter, thereby causing the cam to rock over and alter the line of thrust of the spring such that it seeks to close the hinge.

Abstract: A self-closing hinge comprises a pair of hinge leaves pivotally interconnected by an offset hinge pin. One leaf has a flanged head projecting substantially radially with respect to a sleeve of the other hinge leaf, within which the hinge pin is mounted.

The cam follower comprises a tubular spring-steel member oriented parallel to the hinge pin and generates a force through the head of the other leaf along an axis distally offset relative to the axis of the hinge pin. During closing of the hinge the follower is brought into registration with a pocket formed in the sleeve to effect a rocking movement of the follower about one edge of the pocket to generate a self-closing moment.

The hinge is intended to prevent slamming of the door while allowing enough speed to insure latching. The swing control hinge is housed in a hinge body that may be used as a third hinge. The hinge pin is made up of two cams that have cam parts on them which dissipate energy from conventional spring loaded hinges having helical spring or a block of rubber during the opening cycle of the door and the torsional force from the spring loaded hinges is dissipated in checking the door as it closes to keep the door from slamming.
