A hinge device includes a base member, a lid member connected to the base member via a hinge structure having a hinge pin and a bearing hole loosely receiving the hinge pin. The base member is provided with a first abutting portion adjacent to the hinge structure, and the lid member is provided with a second abutting portion adjacent to the hinge structure so that the lid member can rotate relative to the base member from an open position to a closed position, the first abutting portion and the second abutting portion being configured to abut each other in a direction orthogonal to an axial line of a hinge axis of the hinge structure when an angle formed by the first member and the second member is within a first angular range preceding the closed position.

Tension hinge pins are disclosed. The tension hinge pins include a body with a hollow interior, an opening into the hollow interior, and an expandable body positioned within the hollow interior. The tension hinge pins include an actuator positioned to engage the expandable body and actuate expansion of expandable body to expand at least a portion of the expandable body outward through the opening. The tension hinge pins can be installed in a hinge used for hanging doors.

The invention relates to a hinge for a switchgear cabinet housing, comprising a first and a second hinge half, which can be connected to each other by means of a hinge pin and which can be pivoted relative to each other about a longitudinal axis of the hinge pin, the hinge pin extending only into the first or the second hinge half in a release position and extending into both the first and the second hinge halves in a locking position, wherein the hinge pin is releasably locked by means of at least one spring clip both in the release position and in the locking position. The invention further relates to a corresponding switchgear cabinet housing and to a corresponding method for mounting a door element on a switchgear cabinet body.

A sleeve for use in an assembly for coupling a wristworn device to a first end of a strap. The sleeve has a first end dimensioned to be received in the recess in the inner face of the first lug of a wristworn device, an inner cavity dimensioned to receive therein the first end of a conventional spring bar, and a retractor coupled to the sleeve for urging the first end of the spring bar towards the second end of the spring bar. The second end of the spring bar is coupled to the second lug, the spring bar is coupled to the strap, the first end of the spring bar is positioned in the inner cavity of the sleeve and the first end of the sleeve is coupled to the first lug. A removable retractor for use with a spring bar, which allows for the use of a plurality of spring bars and therefore, lends itself to widespread use and retrofitting of an assembly that couples a strap to a wristworn device, is also provided.

The present disclosure relates to a refrigerator and a hinge for a door of the refrigerator. In accordance with an aspect of the disclosure, there may be provided a refrigerator, including a main body having a storage space capable of storing food, a door configured to selectively open and close or shield the storage space of the main body, and a hinge rotatably fixing the door to the main body, wherein the hinge includes a lower hinge plate fixed to the main body, an upper hinge plate connected to the lower hinge plate, coupled to the door and including a pivot configured to enable the door to rotate, and a connection part connecting the upper hinge plate and the lower hinge plate and enabling the upper hinge to rotate with respect to the lower hinge plate.

A hinge assembly suppressing periodic motions and abrasive wear that supports an axial load and integrated a releasable hinge pin with retractable latch pins. The connector arms for the hinge assembly may include bearings, smooth outer surfaces, and tight fittings to help suppress the periodic motions and abrasive wear. Adjustable mounting apertures reduce stress on the hinge system. A hinge aperture for each member enables an axial load arm, such as thrust bearings, to pass through for reducing periodic movements during pivotal operation. A lock arm can also pass through the hinge apertures. The lock arm uses a locking pin to fasten the members together. A smooth outer surface inhibits abrasive wear and creates a smooth pivoting motion. Non-circular mounting apertures may enable adjustable mounting for reducing stress on the system.

The second end of the spring bar is coupled to the second lug, the spring bar is coupled to the strap, the first end of the spring bar is positioned in the inner cavity of the sleeve and the first end of the sleeve is coupled to the first lug. A removable retractor for use with a spring bar, which allows for the use of a plurality of spring bars and therefore, lends itself to widespread use and retrofitting of an assembly that couples a strap to a wristworn device, is also provided.

Disclosed are a foldable electronic device having a large-screen display and a folding device thereof. The disclosed electronic device comprises: a first electronic device having a first inner surface, a first outer surface, and first side surfaces arranged between the first inner surface and the first outer surface; a second electronic device having a second inner surface, a second outer surface, and second side surfaces arranged between the second inner surface and the second outer surface; and a connection part for connecting the first electronic device and the second electronic device, wherein the second electronic device has a folding part parallel to the connection part and can be thus folded on or unfolded from the first electronic device.
