  • Patent number: 10754391
    Abstract: The description relates to devices that include hinged portions and controlling rotation of the portions. One example can include a display coupled to a first end of an arm. The example can also include a base rotatably secured to a hollow shaft that is fixed to the arm. The hollow shaft defines an axis of rotation of the arm relative to the base. The base can also include first and second opposing axial cam elements positioned on the hollow shaft and a spring positioned on the hollow shaft. The first and second opposing axial cam elements can be oriented relative to one another such that rotation of the arm toward the base causes the first and second axial cam elements to move away from one another along the hollow shaft thereby compressing the spring.

    Abstract: A hinge device prevents breakage of a structuring part from an increase in an internal pressure during overload. In the hinge device, first and second members are rotatable relative to each other. A case is fixed to either the first or second member, and a shaft body capable of rotating relative to the case is fixed to the other. A first chamber and a second chamber formed between the case and the shaft body are filled with viscous fluid. An orifice between the first and second chambers narrows a flow path for the viscous fluid moving from the first to second chamber, resisting rotation of the shaft body. A space region is provided in the shaft body, with a valve body movably placed therein. When pressure of the first chamber reaches a predetermined level, the valve body moves in the space region to increase the volume of the first chamber.

    Abstract: An asymmetrical resistant hinge set includes at least a resistant hinge and an elastic element coaxially positioned. The resistant hinge is hinged on a first pivotal means located on the bottom side of a body. The elastic element provides action forces on the resistant hinge and one-way resistance to generate an asymmetrical hinge effect with a greater resistance in one direction and a smaller resistance in another direction when a support lid is flipped in forward and reverse directions to reduce the resistance of the resistant hinge. As a result, when the support lid is flipped to a selected angle it still can bear the weight of the body of a portable electronic device at the anchored position without drifting.

  • Patent number: 7028373
    Abstract: A hinged housing portion (110) coupled to a second housing portion (120), for example in a wireless communications device, including a compression spring (134) coupled to one of the housing portions, a cam (142) coupled to the body member, and a follower (336) coupled between the cam and the compression spring. The compression spring compresses along a compression axis perpendicular to the axis of rotation. The contoured surface or cam surface urges the follower against a first side of the second housing portion with the follower force 724. The follower force is parallel to the slope of the contoured surface slope at the point of contact between the follower and the contoured surface. The follower force results in rotation of the second housing portion in a first direction or second direction of rotation about the first axis depending on the angle of the contoured surface relative to the compression spring axis.

  • Patent number: 6952860
    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.

  • Patent number: 6910665
    Abstract: An integrated door closing and leveling assembly for a refrigerator includes a spring biased door closure and an adjustable support integrated into a housing. The door closure includes an arm attached to the housing for relative sliding and pivoting movement, while being biased to a retracted position by a spring having an associated noise dampening element. The interaction between the spring and the arm is such that the spring provides a small degree of resistance to any opening force and also serves to maintain the door fully open once the door is opened beyond a critical point. The support structure houses both front and rear wheels for maneuvering the refrigerator, and feet for leveling and supporting purposes.
