A hinge structure includes: a base having an axial hole whose an inner wall has positioning concave portions; at least one torque element, disposed in the axial hole and includes a torque providing portion and positioning convex portions; and a rotation shaft, passing through the through hole. The torque providing portion surrounds a central axis of the axial hole to form a through hole, the torque providing portion has a fracture adjacent to the through hole, and the positioning convex portions are connected to the torque providing portion and correspond to the positioning concave portions respectively. The torque providing portion and the positioning convex portions are located on a same virtual plane perpendicular to the center axis. A first virtual straight line on the virtual plane passes through the fracture and the center axis, and at least some positioning convex portions are not located on the first virtual straight line.

Examples disclosed herein relate to a hinge assembly with a compressible sleeve. In one example, a base member is coupled to an upright member via a hinge assembly. In an example, the hinge assembly include a first securing member, a second securing member including a shaft coupled to the first securing member; a compressible sleeve to engage the shaft, and a spring coupled to the first securing member. In an example, the spring is to engage the compressible sleeve and apply a compressive force on the sleeve in response to a rotational movement of the hinge assembly in a first direction and reduce a compressive force when the hinge assembly is rotated in a second direction.

A hinge arrangement for a switch cabinet, having a switch cabinet body and a switch cabinet door which is fastened thereto via at least two hinges arranged vertically one above the other, at least a first of the hinges, which is arranged above a second of the hinges, having a first body-side hinge half with a first hinge pin which projects vertically upwards from a first pin seat, onto which a first door-side hinge half is fitted, wherein the first hinge pin has an auxiliary mounting position in which it projects from the first pin seat by a first length which is greater than a second length by which a second hinge pin of a second body-side hinge half of the second hinge projects from its second pin seat. A corresponding method is also described.

An object is to provide a hinge which can attach a supporting part for supporting rotatably a holder part easily to the holder part holding the door. A hinge comprises a holder part for holding a door (front-side body receiving a left-and-right adjustment segment and back-side body), a supporting part for supporting rotatably the holder part (resin bush inserted in a rotation shaft), and a connection part (resin catcher) for connecting the holder part to the supporting part, and the resin catcher comprises an attachment part (recesses) for attaching to the holder part and a pawl for gripping elastically the supporting part.

A bearing including a substrate and a low friction layer, where the bearing includes an annular shape including a radial bearing portion in the form of an axially-extending base region, and an axial bearing portion in the form of a radially-extending flange, where the axial bearing portion terminates in a deep drawn axially extending lip, and at least one of a radial coining region or an axial coining region, where the radial coining region is positioned along the radially-extending flange and forms an annular depression, where the axial coining region is positioned along the axially-extending base region, and where the axial coining region is deformed so as to be non-parallel to a longitudinal axis of the bearing.

A protective case for a tablet computer includes a first support plate, a second support plate, and a cover plate that are located in a same horizontal plane and that are sequentially arranged in a first direction, where the first support plate is hinged to the second support plate by using a damping rotating shaft, the second support plate is rotatably connected to the cover plate, a bottom support is disposed on an edge of one end that is close to the cover plate and that is of an upper surface of the second support plate, the first support plate and the second support plate are configured to support and protect a rear surface of a tablet computer, the bottom support is configured to be detachably connected to a side wall of the tablet computer.

A hinge assembly is provided. The hinge assembly includes a first hinge component and a second hinge component. The first hinge component includes a leaf portion terminating in a first knuckle and a second knuckle. The first knuckle includes a protrusion and the second knuckle includes a recess. The second hinge component is rotatably coupled to the first hinge component and is structurally identical to the first hinge component. The protrusion of the first hinge component is configured to fit within the recess of the second hinge component, and the protrusion of the second hinge component is configured to fit within the recess of the first hinge component.
