Refrigerated display case door and method of manufacture
First Claim
1. A closure particularly adapted for accessing a climate controlled compartment comprising inner and outer substantially polygonal annular open frames defining respective inner and outer substantially polygonal border portions, said outer frame defining respective inner and outer substantially polygonal openings, said outer substantially polygonal frame being a single substantially homogeneous polymeric/copolymeric injection molded member, said inner substantially polygonal frame being formed of polymeric/copolymeric material, a substantially polygonal glass assembly having a peripheral edge portion located between said polygonal border portions and closing said outer frame opening, means for peripherally bonding at least one of said frames to said glass assembly, and means for peripherally forcefully snap-securing said frames to each other to substantially immobilize said inner and outer frames incident to solidification/curing of said bonding means.

Abstract
A refrigerated display cabinet IG door includes inner and outer polygonal annular frames each formed as a single substantially homogenous polymeric/copolymeric injection molded member. An insulated glass unit is bonded to the inner and outer frame members which are forcefully held together by a periphery snap fastening mechanism which avoids conventional use of clamps, vises or the like during adhesive cure/set-up. Conventional pivot pins carried by the display doors are uniquely guided into pivot pin openings through guiding and locating members which can be snap-secured in openings of a frame in a display case in but a single position.

- 1. A closure particularly adapted for accessing a climate controlled compartment comprising inner and outer substantially polygonal annular open frames defining respective inner and outer substantially polygonal border portions, said outer frame defining respective inner and outer substantially polygonal openings, said outer substantially polygonal frame being a single substantially homogeneous polymeric/copolymeric injection molded member, said inner substantially polygonal frame being formed of polymeric/copolymeric material, a substantially polygonal glass assembly having a peripheral edge portion located between said polygonal border portions and closing said outer frame opening, means for peripherally bonding at least one of said frames to said glass assembly, and means for peripherally forcefully snap-securing said frames to each other to substantially immobilize said inner and outer frames incident to solidification/curing of said bonding means.
- 15. A frame and closure combination comprising a substantially open frame defining an opening, a closure of a size and configuration to substantially close said opening in a closed position of said closure and frame, pivot means for effecting relative pivoting movement of said closure and opening, said pivot means including at least one pivot pin having a pivot pin end portion in a pivot pin opening for effecting relative pivoting movement about a common pivot axis, said pivot pin and pivot pin opening being carried one each by one of said closure and frame, and means for relatively guiding said pivot pin and pivot pin opening during frame and closure assembly from a first position at which an axis on one of said pivot pin and pivot pin opening is offset from said common pivot axis to a second position at which said pivot pin, pivot pin opening and common pivot axis are substantially coaxial.
- 33. A guide member adapted for assembling relatively movable elements from a first unassembled position to a second assembled position at which the first and second elements are respectively substantially axially misaligned and substantially coaxial comprising a guide member body defined by an opposite end surfaces and an outer peripheral surface between said opposite end surfaces, an inner peripheral surface of said guide member body defining an opening extending between said opposite end surfaces, and means for guiding an element for movement from a first position of misalignment relative to an axis of said opening and outboard therefrom to a second position of substantially coaxial alignment with said opening axis.
- 51. A structural unit comprising a first frame formed of molded synthetic polymeric/copolymeric plastic material, said first frame being defined by a peripheral wall and relatively spaced inwardly projecting inner and outer walls terminating in respective inner and outer terminal edges, said inner and outer wall terminal edges defining respective inner and outer openings, said inner opening being larger than said outer opening, a glass assembly, said glass assembly having a peripheral edge of a size to pass through said inner opening along a path substantially parallel to an axis of said inner opening but a size too large to pass through said outer opening, said glass assembly being located contiguous aid first frame outer wall, means for bonding said glass assembly to said first frame, a second frame located contiguous a second side of said glass assembly, and means for snap-securing said first and second frames to each other.
-
58. A method of manufacturing a closure comprising the steps of providing a polygonal annular outer frame having an inner polygonal opening larger than an outer polygonal opening, a polygonal glass unit having a peripheral edge portion larger than the outer opening but smaller than the inner opening and an inner polygonal annular frame having inner and outer peripheral edge portions;
- inserting the glass unit through the larger opening into the outer frame, bonding the glass unit peripheral edge portion and the outer frame to each other, bonding the inner peripheral edge portion of the inner frame to the glass unit, and securing the outer peripheral edge portion of the inner frame to the outer frame under sufficient peripheral force to substantially immobilize the inner and outer frames incident to solidification/curing of the bonding material utilized during the performance of the bonding steps.
