Abstract

A refrigerated cabinet (10) includes a cabinet base (20) defining an open top compartment having a refrigerated interior for housing a refrigerated product (50) and a canopy (30) disposed atop the refrigerated compartment. A transparent glass window in the front wall of the canopy (30) is extended downwardly to the product fill line within the refrigerated compartment thereby expanding the customer view area. The rear wall of the canopy (30) includes a transparent service door (40) and a framework (42). The service door (40) may be rotated independently of the framework (42) to an open position providing service access to the refrigerated compartment. The service door (40) and the framework (42) may also be rotated together as a unit to a second open position to provide access to the refrigerated compartment for cleaning and sanitizing. A lamp (80) for illuminating the cabinet interior is disposed externally of the canopy (30).

Claims

1. A refrigerated cabinet comprising:

a cabinet base having a front wall, a back wall and end walls defining an open top compartment having a refrigerated interior for housing a refrigerated product;

a canopy disposed atop said compartment, said canopy having a front wall having a transparent window through which the cabinet interior may be viewed, and a back wall having a transparent service door and a framework about said service door, the service door being hinged to the framework for rotation independently of the framework;

support system operatively interconnecting the framework with at least one of the end walls of the cabinet and independently operatively interconnecting the service door with at least one of the end walls of the cabinet, said support system being actionable in a first manner to rotate said service door inwardly between an open position and a closed position independently of said framework and being actionable in a second manner to rotate said service door and said framework together outwardly as a unit between a closed position and an open position.

2. A refrigerated cabinet comprising:

a cabinet base having a front wall, a back wall and end walls defining an open top compartment having a refrigerated interior for housing a refrigerated product;

a canopy disposed atop said compartment, said canopy having a front wall having a transparent window through which the cabinet interior may be viewed, and a back wall having a transparent service door and a framework about said service door, the service door being hinged to the framework for rotation independently of the framework;

a first gas cylinder operatively interconnecting the service door with one of the end walls of the cabinet for movement inwardly independently of the framework; and

a second gas cylinder operatively interconnecting the framework with one of the end walls of the cabinet for movement of the framework and the service door together outwardly between a closed position and an open position.
