Abstract: A refrigerator door is disclosed which comprises a plurality of extruded aluminum frame members of predetermined configuration, each having a number of channels on its inner surface; L-shaped alignment pins for attachment of the frame members to each adjacent member so as to form a frame of predetermined configuration, a groove for thermally insulating a front portion of the extruded aluminum members from a rear portion; front and rear panel members positioned in parallel non-contacting substantially perpendicular alignment in the channels of the frame members; a thermal insulation medium positioned within the space between the frame members and the front and rear panels; and hinge brackets for mounting the frame members upon a refrigeration cabinet by hinged connections.

Abstract: A hinge for rotatably mounting a barrier member to a structural member. The hinge comprises a first hinge assembly which comprises a first hinge bracket attachable to the structural member, a second hinge bracket attachable to the barrier member, a first hinge member mounted for rotation with the second hinge mounting bracket and a second hinge member mounted for rotation with the first hinge member. Both hinge members have correspondingly configured engaging surfaces which permit staged rotation between the hinge members. This facilitates a staged rotation of the barrier member in predetermined sequential increments as determined by the engaging surfaces. This first hinge assembly connects a lower portion of the barrier member to the structural member and is responsible for bearing substantially all of the weight of the barrier member. The invention further comprises at least a second hinge assembly for providing rotational alignment between an upper portion of the barrier member and the structural member.

Abstract: A system for supporting a refrigeration cabinet is disclosed wherein the cabinet has a base or lower portion on which it rests. The system includes roller support means mounted to the base portion of the cabinet at a first location closest to the front accessible part of the cabinet and roller support means mounted to the base portion of the cabinet at a second location remote from the first roller support. This last mentioned roller support is usually positioned at the rear corner of the cabinet which is normally inaccessible in built-in appliances. An adjusting mechanism is provided for conveniently adjusting the dimension between the base portion of the refrigerator cabinet and the first roller support. This adjusting mechanism is located at the first mentioned accessible location closest to the front part of the cabinet.

Abstract: A hinge for rotatably mounting a barrier member to structural means which comprises first hinge mounting means having means for attachment thereof to the structural means; second hinge mounting means having means for attachment thereof to the barrier member; a first hinge member mounted for rotation with the second hinge mounting means; a second hinge member positioned in engagement with the first hinge member and means for preventing rotation of the second hinge member with respect to the first mounting means. Each hinge member has corresponding engaging surfaces configured to permit a staged rotation of the barrier means into a plurality of predetermined positions. Applicants have also developed a novel method for constructing the hinge of the invention.
