Abstract: A multi-link hinge assembly includes a link rod unit including a base rod, two supporting link rods, two synchronization link rods, two supporting rods, and a supporting plate unit. The base rod has a base rod body, two base connecting portions respectively connected to opposite ends of the base rod body, and two central connecting portions disposed between the base connecting portions. Each synchronization link rod has a first synchronization end portion pivotably connected to a respective one of the central connecting portions, and a second synchronization end portion opposite thereto. The supporting plate unit includes two supporting plates respectively connected to the supporting rods and each having inner and outer portions. The link rod unit is operable between an unfolded position and a folded position, where the second synchronization end portions are away from each other, and the inner portions define a relief space therebetween.

Abstract: A wall vent door assembly including a multi-functional hinge including flexible and resilient material extending continuously along the hinge edge of the door; one edge of the door is configured to accept and/or otherwise interface with a complimentary edge of the hinge material, and the adjacent hinge edge of the mounting frame is configured to accept and/or otherwise interface with another complimentary edge of the hinge material. Besides providing the hinge connection between the door and the adjacent frame, the flexible material also seals the interface to prevent entry of light and wind when the door is closed. The flexible and resilient hinge material also acts as a spring, exerting force to assist in the movement of the door from the closed position to open positions.

Abstract: The invention relates to a hinge (10) comprising a swivellable hinge part (12), a stationary hinge part (14) and a tensionable spring element (34), wherein the stationary hinge part (14) is designed with a first bearing (16) as well as a second bearing (18), wherein the bearings (16, 18) have swivel axes (S1, S2) that are offset to one another. According to the invention, the swivellable hinge part (12) is mounted on the stationary hinge part (14) via the first bearing (16) such that it can swivel about a swivel axis (S1), and the tensionable spring element (34) is arranged on the stationary hinge part (14) via the second bearing (18).

Abstract: In an example, a hinge may include a first hinge component having a first friction surface, and a second hinge component having a second friction surface. The second hinge component may be rotatably engaged with the first hinge component such that the first friction surface and the second friction surface are abutted against each other and are to move relative to one another if the first hinge component and the second hinge component are moved relative to one another. The hinge may include a graphene coating disposed on either of the first friction surface, or the second friction surface.

Abstract: A joining structure for two door members forming a door member for entrance opening and closing of an aircraft lavatory unit is configured so that a pair of brackets provided on the pair of door members are joined swingably by a bracket joining shaft; and one ends of a pair of covers are joined to the pair of brackets by bracket cover joining shafts, and the other ends of the pair of covers are joined swingably by a cover joining shaft, at a section farther away from the lavatory than the bracket joining shaft.

Abstract: A hinge mechanism is provided, including a rotary member, a first member, a second member, a first shaft, and a first slider. The first member has a first guiding channel. The second member pivotally connects to the first member and has a first recess. The first shaft pivotally connects the rotary member and the first member, wherein the first shaft has a first cavity. The first slider is movable between the first recess and the first cavity. When the first slider is located in the first recess, the first member is prohibited from rotating relative to the second member by the first slider. When the first slider slides from the first recess along the first guiding channel to the first cavity, the rotary member is prohibited from rotating relative to the first member by the first slider.

Abstract: A hinge is provided, which comprises: at least one hinge pin defining a hinge axis in a first dimension; a hinge leaf; a housing comprising at least one recess for receiving a portion of the hinge leaf; and at least one user adjustable fastener arranged to enable user adjustment of the positioning of the hinge leaf within the at least one recess in a second dimension, wherein the second dimension is orthogonal to the first dimension.

Abstract: Provided is a stay which is capable of stabilizing movement of a component part used for transmitting, or not transmitting, the torque of one of a first member and a second member to the other. When a second member rotates relative to a first member in one direction, a cam base moves away from a disk in the direction of the rotation axis, and the second member and the cam base rotate relative to the first member and the disk. When the second member rotates relative to the first member in the opposite direction, the cam base moves towards the disk in the direction of the rotation axis, and the second member, the cam base and disk rotate relative to the first member with resistance force.

Abstract: A hinge, particularly for movable pieces of furniture, has at least two stop parts connected in an articulated manner (which is to say a hinge arm and a hinge cup) for fastening to pieces of furniture. The hinge has a damping device for damping the hinge movement, and has a restoring mechanism, by which an actuating element of the damping device can be moved into a starting position for the next damping stroke after damping has taken place. The damping device and the restoring mechanism are disposed as separate components on the hinge cup. The damping device, which has no restoring mechanism, is disposed on a lateral wall of the hinge cup, and the restoring mechanism is disposed on an opposing lateral wall of the hinge cup.
