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.

The hinge assembly comprises a housing for mounting on a cabinet and a post member for mounting on a door and for rotation relative to the housing. A first electrical contact is mounted within the housing for connection to a source of electrical power in the cabinet and a second electrical contact is disposed in the post in electrical contact with the first contact for connection to an electrical appliance in the door. In one embodiment, the electrical contacts rotate relative to each other as the post member pivots on the housing while in other embodiments; the electrical contacts remain stationary relative to each other as the post member pivots on the housing.

A display case door assembly for a temperature-controlled storage device includes a vacuum panel, a hinge rail, and a lighting element. The vacuum panel includes a first vacuum pane, a second vacuum pane, and an evacuated gap between the first and second vacuum panes. The evacuated gap provides thermal insulation for the vacuum panel. The hinge rail is coupled to an edge of the vacuum panel and configured to rotate along with the vacuum panel between an open position and a closed position. The lighting element is coupled to at least one of the edge rail and the vacuum panel and configured to emit light toward an interior of the temperature-controlled storage device when the hinge rail and vacuum panel are in at least the closed position.

A hinge construction includes a hinge bracket that includes a hinge pin supporting plate and at least one opening extending through the hinge pin supporting plate. Also included in the hinge construction is a hinge pin that is held at the at least one opening. The hinge pin includes a hinge pin outer surface, a hinge pin bore extending through the entire length of the hinge pin and a hinge pin slot extending along the entire length of the hinge pin from the hinge pin outer surface to within the hinge pin bore. The at least one opening can be tapered, and the hinge pin outer surface can include a hinge pin outer surface first portion that also is tapered so as to be congruent with the at least one tapered opening. The hinge construction allows elements such as electrical wiring to be routed through the hinge construction.

A shower door hinge mechanism (201) for a half-height shower door, operable to lift the shower door (203) to remove any contact between the bottom seal element (209) and the shower floor area (203). The hinge mechanism (201) comprises first and second co-operable hinge parts (204, 205) mountable to a shower door (203), and a manually-operable element (206) engageable with at least one of the first and second parts (204, 205) such that operating the manually-operable element (206) causes one of the first and second parts (204, 205) to be moved into a raised position relative to the other. Shower door apparatus (202) comprising the hinge mechanism (201), and a shower door installation (301) comprising the shower door apparatus (202). A method of enabling a shower door (203) to be lifted to enable rotation of the shower door (203) free of contact with the shower area floor.

A self closing and adjustable closing force cam hinge includes a compression spring located on the hinge so that a hinge pin passes through the compression spring and the head of the hinge pin is retracted in a direction away from the compression spring to compress the compression spring. Compression of the spring applies a closing force to the hinge when the hinge is in the open position. The hinge also includes a spring adjuster having an adjustably positionable body that is adjustably positionable relative to the head of the hinge pin. Adjustment of the position of the adjustably positionable body raises or lowers the head of the hinge pin such that raising of the hinge pin increases compression of the compression spring to increase the closing force applied by the compression spring and lowering of the hinge decreases compression of the compression spring to decrease the closing force applied by the compression spring.
