Abstract

A temperature-controlled display case is convertible between a full-service mode and a self-service mode and defines a temperature-controlled space therein. A base has a back side and a front side and supports temperature-controlled food products within the temperature-controlled space. A back frame is coupled adjacent to the back side of the base and provides one or more openings for back-side access to the food products during the full-service mode. A top frame is supported by the back frame and a linkage has one end pivotally coupled to the top frame. A front panel has a top portion pivotally coupled to the linkage and is movable between a deployed position for the full-service mode with the front panel adjacent to the front of the base, and a stowed position for the self-service mode with the front panel disposed atop the top frame to provide front-side access to the food products.

First claim

What is claimed is:

1. A temperature-controlled display case convertible for operation in a full-service mode and a self-service mode, the temperature-controlled display case defining a temperature-controlled space therein and comprising:
a base having a back side and a front side, and configured to support temperature-controlled food products within the temperature-controlled space;
a back frame coupled adjacent to the back side of the base and providing one or more openings configured to provide back side access to the food products during the full-service mode;
a top frame supported by the back frame;
a linkage having one end pivotally coupled to one of the back frame and the top frame;
a front panel having a top portion pivotally coupled to an opposite end of the linkage and movable between a deployed position for the full-service mode with the front panel adjacent to the front side of the base, and a stowed position for the self-service mode with the front panel disposed atop the top frame to provide front side access to the food products.

2. The temperature-controlled display case of claim 1 , wherein the food products comprise heated food products and wherein the base further comprises heating elements and thermal insulation configured to maintain a temperature of the hot food products.

3. The temperature-controlled display case of claim 1 , wherein the food products comprise refrigerated food products and wherein the base further comprises a cooling coil and a fan configured to circulate refrigerated air through the temperature-controlled space.

4. The temperature-controlled display case of claim 3 , further comprising a switch operable to change a speed of the fan or an operating condition of the cooling coil when the front panel is moved from one of the deployed position or the stowed position to the other of the deployed position or the stowed position.

5. The temperature-controlled display case of claim 4 , wherein the switch is configured to be operated automatically upon movement of the front panel.

6. The temperature-controlled display case of claim 1 , wherein the front panel provides a substantially horizontal display platform supported by the top frame in the stowed position.

7. The temperature-controlled display case of claim 1 , further comprising a torsion spring operably associated with the linkage to assist upward movement of the front panel and to resist downward movement of the front panel.

8. The temperature-controlled display case of claim 1 , wherein the base, the back frame, the top frame and the front panel are all disposed within an upper portion, and the upper portion is disposed upon a lower portion, the lower portion comprising another temperature controlled space that is independent from the first temperature controlled space.

9. A temperature-controlled display case convertible for operation in a back-access mode and a front-access mode, the temperature-controlled display case defining a temperature-controlled space therein and comprising:
a base having a back side and a front side, and configured to support temperature-controlled products within the temperature-controlled space;
a back frame from the base;
a top frame supported by the back frame;
a pivot member having one end coupled to at least one of the back frame and the top frame;
a front panel having a top portion pivotally coupled to the pivot member and movable between a deployed position with the front panel enclosing the front side of the base,
and a stowed position for the front-access mode with the front panel disposed atop the top frame to provide front side access to the food products.

10. The temperature-controlled display case of claim 9 , wherein the food products comprise heated food products and wherein the base further comprises heating elements and thermal insulation configured to maintain a temperature of the hot food products.

11. The temperature-controlled display case of claim 9 , wherein the food products comprise refrigerated food products and wherein the base further comprises a cooling coil and a fan configured to circulate refrigerated air through the temperature-controlled space.

12. The temperature-controlled display case of claim 11 , further comprising a switch operable to change a speed of the fan or an operating condition of the cooling coil when the front panel is moved from one of the deployed position or the stowed position to the other of the deployed position or the stowed position.

13. The temperature-controlled display case of claim 12 , wherein the switch is configured to be operated automatically upon movement of the front panel.

14. The temperature-controlled display case of claim 9 , wherein the front panel provides a substantially horizontal display platform supported by the top frame in the stowed position.

15. The temperature-controlled display case of claim 9 , further comprising a torsion spring operably associated with the linkage to assist upward movement of the front panel and to resist downward movement of the front panel.

16. The temperature-controlled display case of claim 9 , wherein the base, the back frame, the top frame and the front panel are all disposed within an upper portion, and the upper portion is disposed upon a lower portion, the lower portion comprising another temperature controlled space that is independent from the first temperature controlled space.

17. A method of providing a temperature-controlled display case convertible for operation in a full-service mode and a self-service mode, comprising:
providing a base having a back side and a front side;
providing a back frame coupled to the base and having one or more openings configured to provide back side access to the food products during the full-service mode;
providing a top frame supported by the back frame;
providing a linkage having one end pivotally coupled to at least one of the back frame and the top frame;
pivotally coupling a top portion of a front panel to an opposite end of the linkage, so that the top panel is movable between a deployed position for the full-service mode with the front panel adjacent to the front side of the base, and a stowed position for the self-service mode with the front panel disposed above the top frame to provide front side access to the food products.
