  • Patent number: 11612069
    Abstract: The disclosure generally relates to an exemplary hinge of an enclosure that can house an electrical network protection element and provide protection to the electrical network protection element against damage in various environments such as when the enclosure is placed in an underground vault that may be flooded during rain, or when a liquid (e.g., oil) comes into contact with the enclosure. The hinge may include two portions, one portion attached to one or more doors of the enclosure and one portion attached to a housing of the enclosure. The hinge may be configured such that it may be adjusted in multiple directions (for example, beyond one plane of rotation that typical hinges may offer), and thus allow for greater adjustability of the one or more doors of the enclosure relative to the housing of the enclosure.

  • Patent number: 10012014
    Abstract: A hinge arrangement includes a first hinge plate assembly including a pivot housing movable about a pivot axis and including a threaded adjustment pin transverse to the pivot axis away from the housing. A second hinge plate assembly includes an adjustment housing, the adjustment housing including a threaded portion. The threaded adjustment pin is threaded into the adjustment housing to connect the first hinge plate assembly to the second hinge plate assembly. Relative rotation between the threaded adjustment pin and the threaded portion of the adjustment housing causes the second hinge plate assembly to move along a length of the threaded adjustment pin, altering a spacing between a mount plate portion of the first hinge plate assembly and a mount plate portion of the second hinge plate assembly. A connection between the pivot housing and the first hinge plate assembly may include a torsional and/or gravity closing bias.

  • Patent number: 8839489
    Abstract: A height adjustment device for a transit shaft and arm assembly that enables height adjustments without significant disassembly of a transit door. An additional advantage is that the device does not require the use of shims, spacers or adjustment rings to adjust the height of the shaft and arm assemblies. Rotation of a nut threaded on the shaft allows for the adjustment of how much of the shaft hangs below a support member and a bearing. A surface of the nut bears on the bearing and the attached shaft and arm assembly hangs from the bearing and the support member the bearing is attached to. This arrangement allows the arm assembly to pivot along the longitudinal axis of the shaft. This arrangement also allows the height of the shaft and arm assembly to change with changes in position of the nut by threading the nut along the shaft.

The hinge body can be pivotally engaged with the base hinge member. A self locking latch can be pivotally engaged with the base hinge member. When the hinge body is rotated around the first axis of rotation, the protruding latch engagement member can contact the self locking latch and can rotate the self locking latch around the second axis of rotation opposite to the bias direction. The self locking latch can rotate around the second axis of rotation in the bias direction and can block the hinge body from rotating around the first axis of rotation.

    Abstract: A refrigerator comprises: a body having a storage chamber; a door for selectively shielding the storage chamber; a hinge coupling portion for hinge-coupling the door to the body; and a height control unit for lifting up or lowering the door by repeatedly opening and closing the door. Since the door has a controllable height by being opened and closed, a moment arm becomes longer than when using the conventional tool such as a spanner. This may allow the height of the door to be controlled by using less force. Since the height of the door is controllable at a user's eye height, the user may control the height of the door more rapidly and precisely without errors.
