Abstract
Abstract A refrigerated cabinet having a canopy supported over an opening in the cabinet by a frame and normally resting on a surface of the cabinet which surrounds the opening, and having a substantially vertical panel of canopy canope which is slidably mounted in and supported by an oversized channel of the frame for limited vertical displacement from the surface of the cabinet to permit thorough cleaning of the surface and of the panel. When cleaning is desired, it can be accomplished by temporarily displacing the substantially vertical panel upwardly into the oversized channel. When the panel is vertically displaced from the surface of the cabinet, both the surface and the lower portion of the panel can be wiped clean by use of a suitable cleaning agent. When the cleaning process is completed, the panel can be lowered, causing the panel to once again be supported by the oversized channel in a normal position in which the lower edge of the panel is resting on the surface of the cabinet surrounding the opening therein.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
192 words
A refrigerated cabinet having a canopy, said cabinet having a plurality of vertical walls attached to define a top opening in said cabinet, said walls having top edges, and said canopy being supported by a frame on said top edges, said frame supporting a front panel, a back panel, a pair of side panels and a top panel of said canopy, at least one of said panels serving as an access door panel and being movably mounted on said frame for movement from a closed position in which said canopy covers said top opening to a fully open position in which said top opening is substantially exposed to the outside environment, and at least one other of said panels having a lower edge normally directly engaging a corresponding top edge of one of said walls, said other panel being slidably mounted in a channel of said frame and being restrained by said frame and channel to limited upward displacement to temporarily separate the lower edge of said slidably mounted panel of said canopy from said top edge of said wall for cleaning said panel and wall edge without substantially opening said cabinet.
Claim 2
Dependent Claim
192 words
A refrigerated cabinet having a canopy, said cabinet having a plurality of vertical walls attached to define a top opening in said cabinet, said walls having top edges, and said canopy being supported by a frame on said top edges, said frame supporting a front panel, a back panel, a pair of side panels and a top panel of said canopy, at least one of said panels serving as an access door panel and being movably mounted on said frame for movement from a closed position in which said canopy covers said top opening to a fully open position in which said top opening is substantially exposed to the outside environment, and at least one other of said panels having a lower edge normally directly engaging a corresponding top edge of one of said walls, said other panel being slidably mounted in a channel of said frame and being restrained by said frame and channel to limited upward displacement to temporarily separate the lower edge of said slidably mounted panel of said canopy from said top edge of said wall for cleaning said panel and wall edge without substantially opening said cabinet.
Claim 3
Dependent Claim
56 words
The refrigerated cabinet of claim 1 in which said canopy comprises a pair of substantially vertical side panels, a substantially vertical front panel, a substantially horizontal top panel and a back panel and in which at least one of said substantially vertical panels is slidably mounted in said channel of said frame for limited vertical displacement.
Claim 4
Dependent Claim
51 words
The refrigerated cabinet of claim 2 in which said back panel is movably mounted on said frame for movement from a closed position to a fully open position and in which said pair of substantially vertical side panels and said substantially vertical front panel are slidably mounted for limited vertical displacement.
Claim 5
Dependent Claim
88 words
The refrigerated cabinet of claim 3 in which said frame has at least four substantially vertical struts and at least four substantially horizontal support beams, said frame having lower ends of each of said struts attached to said cabinet, and having a first end of each substantially horizontal support beam attached to an upper end of a substantially vertical strut and a second end of each substantially horizontal support beam attached to an upper end of a next adjacent substantially vertical strut, said frame forming a box-like structure.
Claim 6
Dependent Claim
85 words
The refrigerated cabinet of claim 4 in which each substantially horizontal support beam of said frame provided for a slidably mounted panel has an oversized channel of a depth sufficient to support said panel in said frame and to permit limited vertical displacement of said panel and in which each substantially vertical strut of saiD frame provided for a slidably mounted panel has a channel of a limited depth sufficient to support said panel in said frame and to permit slidable movement of said panel.
Claim 7
Dependent Claim
42 words
The refrigerated cabinet of claim 4 in which said four substantially vertical struts comprise two front struts and two back struts and in which each front strut converges with a next adjacent back strut from said lower ends to said upper ends.
Claim 8
Dependent Claim
140 words
The refrigerated cabinet of claim 6 in which said substantially horizontal support beams of said frame attached to said upper ends of each front strut and next adjacent back strut and said substantially horizontal support beam attached to said upper ends of both front struts have oversized channels of a depth sufficient to support said slidably mounted panels in said frame and to permit limited vertical displacement of said panels, each front strut and next adjacent back strut having an oversized channel of a depth sufficient to support a substantially vertical side panel in said frame and to permit limited vertical displacement of said side panel, and each front strut of said frame having a channel of a limited depth sufficient to support said substantially vertical front panel in said frame and to permit slidable movement of said front panel.
