A self-closing hinge has a housing shaft section with a bore extending therethrough in a direction substantially parallel to a longitudinal axis is attachable to a first rotatable member. A bore extends through the housing shaft section. The cross-sectional profile of the bore in a plane orthogonal to the longitudinal axis has at least one arcuate portion and at least one non-arcuate portion. A roll pin rotatably disposed in the bore has substantially the same cross-sectional profile as the bore. A pair of shaft members, each having a shaft-member body attachable to a second rotatable member, has a pin inserted in an interference fit in the opposed ends of the roll-pin bore. The pins have a cross-sectional profile corresponding to the roll-pin cross-sectional profile.

A rotating coupling system for a closing element, such as a door, window, door or the like, and a stationary support structure, such as a wall, floor, frame or the like includes a hinge device anchorable to the closing element and a mounting plate anchorable to the stationary support structure. The hinge device has a hinge body and a pivot defining a first axis, and are coupled each other to rotate one with respect to the other around the axis. In particular, the pivot includes a coupling portion, which protrudes from the hinge body, and the mounting plate includes a plate-shaped body having a seat that receives the coupling portion of the pivot. The plate-shaped body further includes an adjusting member to adjust its position with respect to the stationary support structure.

The present invention provides a hinge and a refrigerator having the same. The hinge has a fixing plate, a supporting plate perpendicularly connected with the fixing plate, and a hinge shaft perpendicularly mounted on the supporting plate to cooperate with a shaft sleeve, wherein the outside of the hinge shaft is plastic-encapsulated with a plastic encapsulating case, the plastic encapsulating case is provided with a protrusion protruding horizontally outwards along the extension direction of the supporting plate, and the protrusion is integrally formed with the plastic encapsulating case.

An appliance includes an outer cabinet having a front aperture for accessing a processing space. A door selectively engages the front aperture in a closed position to enclose the processing space. A hinge includes a cabinet mount attached to the outer cabinet and having a stop that defines an open position of the door. A hinge pin extends through the cabinet mount to define a rotational axis of the hinge. A sheet metal flange is press fit onto the hinge pin and is fixedly attached to the door. The sheet metal flange is wrapped around the hinge pin and is attached to the door via fasteners. The pin includes a protrusion that selectively engages the stop of the cabinet mount in the open position.

Systems and methods of co-printing a unitary hinge are provided. The unitary hinge may be co-printed using an additive manufacturing process. The unitary hinge includes a hinge pin that is substantially cylindrical in shape. The unitary hinge also includes a knuckle which surrounds a portion of the hinge pin and is configured to be manipulated about the hinge pin. The hinge pin is fabricated in situ with the knuckle such that further assembly is unnecessary. The unitary hinge may also include retention mechanism to retain the hinge within the knuckle without substantially restricting the knuckle from being rotated about the hinge pin. The unitary hinge may further be configured with a fluid port which may, for example, be used to provide a lubricant to an area between the hinge pin and the knuckle or to vacuum powder material or debris from the area.

A hinge for cold rooms or glass shutters, coupling a stationary support structure and a shutter movable between an open position and a shutter position, includes a hinge body having a working chamber; a pivot defining a first longitudinal axis coupled to the hinge body to rotate around the first axis between the open and the closed shutter position; a cam element integral with the pivot; a plunger element sliding in the working chamber along a second axis substantially perpendicular to the first axis, the plunger element having a slider with an operative face interacting with the cam element; and an elastic counteracting member acting upon the plunger element to move it along the second axis between a position proximal to the bottom wall of the working chamber and a position distal therefrom. The hinge body has a substantially plate shape.

A self-closing hinge has a housing shaft section with a bore extending therethrough in a direction substantially parallel to a longitudinal axis is attachable to a first rotatable member. A bore extends through the housing shaft section. The cross-sectional profile of the bore in a plane orthogonal to the longitudinal axis has at least one arcuate portion and at least one non-arcuate portion. A roll pin rotatably disposed in the bore has substantially the same cross-sectional profile as the bore. A pair of shaft members, each having a shaft-member body attachable to a second rotatable member, has a pin inserted in an interference fit in the opposed ends of the roll-pin bore. The pins have a cross-sectional profile corresponding to the roll-pin cross-sectional profile.

A hinge structure connected between two bodies of an electronic device is provided. The bodies are rotated to be folded or unfolded relatively through the hinge structure. The hinge structure includes a first rotating shaft, a second rotating shaft, and a torsion member that the first and the second rotating shafts being pivoted thereto, such that the torsion member surrounds and grasps an axial surface of the first rotating shaft and an axial surface of the second rotating shaft respectively. The first rotating shaft has a first actuating portion and a second actuating portion. The second rotating shaft has a third actuating portion and a fourth actuating portion. The torsion member has a first torsion providing portion located on a moving path of the first and the second actuating portions and a second torsion providing portion located on a moving path of the third and the fourth actuating portions.

An electric cooker having a base body provided with an electric heater, a lid member provided with an electric heater and pivotably supported to the base body by a hinge shaft, and a hinge-shaft-height adjustment mechanism for adjusting the vertical position of the hinge shaft. The hinge-shaft-height adjustment mechanism includes a support portion mounted on the base body, an adjustment guide hole formed on the support portion to have a wide-width portion and a narrow-width portion alternately in a vertical direction, the hinge shaft formed with an engaging shaft portion which is engaged with the adjustment guide hole to be capable of moving vertically and rotating, and an operating lever pivoting with the hinge shaft. The engaging shaft portion moves from either the wide-width portion in an upper or lower side to the other of those through the narrow-width portion by rotating according to operation of the operating lever.

A furniture connector connects two or more pieces of furniture together or may connect furniture to a wall, embodied, for example, as an adjustable room partition or modular storage unit. The furniture connector has a first spoke and a second spoke, which may be connected to a furniture piece or wall via respective locking mechanisms. The first and second spokes are joined by a pin, along a longitudinal axis of the pin. The connector allows the positions of two attached furniture pieces (or a furniture piece and a wall) to be adjusted about the longitudinal axis at a variety of discrete angles; once set to a desired angle, the connector limits the relative rotational movement of the first spoke and second spoke (about the longitudinal axis.) Other embodiments are also described and claimed.
