Abstract: Curtain structure for substantially covering the access opening of an open-sided, display-type, refrigerated food cabinet. A first curtain comprises a flexible sheet prestressed to roll up and fixed at its upper edge to the ceiling of the cabinet inboard of the access opening. The first curtain may be unrolled and its bottom edge attached to the floor of the cabinet to substantially block air movement into and out of the cabinet. A second curtain comprises a plurality of side-by-side, elongate strips of flexible transparent sheet material, fixed together at their upper ends and supported on the cabinet at the top of the access opening. The lower ends of the strips are free of each other and terminate slightly above the bottom of the access opening. The second curtain is spaced away from the closed position of the first curtain by an air layer providing a thermal barrier across the access opening when access to the interior of the cabinet is not needed.

Abstract: A cold display case which can be assembled easily and quickly on the spot without particular specialized skill is provided. Frames for the cold display case are constructed with generally rectangular pipes and connectors, said connectors each having a main body and a plurality of engaging arms crossing at right angles to each other.

Abstract: Energy losses from market refrigerated display cases, which are normally open, can be dramatically reduced by use of an access shield according to the present invention. The access shield comprises a plurality of transparent and resilient panels, each panel being adjacent to at least one other and having an overlapping relationship with the adjacent panel. The panels may be mounted in a rigid frame and allow access therethrough by stretching and bending of one or more of the panels along the overlapped line. The plurality of panels may also be fitted to a spring tensioned roller and stretched across the aperture of the display refrigeration case. In another embodiment, the plurality of panels may each be attached at an opposite ends to a holder having a bow tie shaped protrusion which is urged into a receiving indentation a fixture to temporarily lock the panel in a predetermined position and yet to permit free rotation within a sector to facilitate access.

Abstract: A deep-freeze cabinet provided with a closure comprising a pair of transparent, rigid sheets of a thermoplastic material which are bonded to each other and form a sealed double-walled enclosure having a peripheral flange. The closure may be contained in a surrounding metal frame or, preferably, is frameless with securing means, for attaching the closure to hinges on the deep-freeze cabinet, passing through spaced walls of the enclosure.

Abstract: A removable insulating cover for a display type refrigerating cabinet is formed of spaced sheets of flexible plastic secured along their edges and along spaced seam lines extending parallel to the length of the cover to form narrow contiguous panels. Relatively thick layers of loosely packed glass fibers fill the panels. The cover is adapted to be suspended across the opening of the cabinet to prevent a transfer of heat through the opening and into the interior of the cabinet during certain periods of time.

Abstract: A multi-curtain, open front refrigerated display case having unique energy saving capacity as a result of the combination of an attached, retractable night curtain specially located between the refrigerated air curtain and the adjacent warmer guard curtain and upon which frost and ice form during closed store hours, with a reverse air defrost flow system that melts the front and ice from the curtain surface prior to retraction thereof at store opening time.

Abstract: A walk-in cooler construction designed to be built into a corner of a room which is complete in and of itself together with hydroplaster walls, fiberglass and urethane insulation throughout, and at least one insulated entrance door. The cooler is complete with refrigeration unit of sufficient cooling capacity to keep the entire inside thereof at a desired low operating temperature. Provision is made to have a plurality of beverage can-supporting racks mounted adjacent multiple access doors for permitting a large number of cans of beer and the like to be kept at sufficiently cool temperture ready for immediate dispension and drinking thereof. A structure is also provided for supporting a plurality of draft beer kegs together with appropriate dispensing means therefor. Lighting structure, shelf and drain structure also are provided. Several modifications of the dispensing rack structure are also included.

Abstract: An improved device and method for displaying and suspending packaged articles is provided. The device includes at least one arm from which articles may be hung, preferably within a display case. The method includes contacting such suspended articles with a conditioned environment. In one embodiment, particularly well suited for use within a conditioned-environment display case, pairs of arms are staggered and lie along planes perpendicular to each other.

Abstract: A hot food counter is disclosed having a lower heated section for storage of food and an upper heated section for display of food. The upper section is enclosed with food being placed into the upper section by service personnel through sliding doors at the rear wall thereof, while food is withdrawn by customers through a pair of contoured openings in the front wall. The enclosure for the upper section is preferably transparent except for the sliding doors in the rear walls which preferably have mirror finishes, and the tray within the enclosure and upon which food is displayed is preferably inclined downwardly and forwardly, as is the top wall of the enclosure.

Abstract: A horizontally disposed shelf having an upstanding end wall adapted to be connected in cantilever fashion to a horizontal support bar on the forwardly disposed wall surface above food displayed in an open top refrigerated food display case.
