Abstract

A modular food display case system permits a particular display case arrangement to be easily customized from a basic design. A plurality of modular bed sections, which are pre-manufactured from a lightweight composite honeycomb material, are used as the basic building blocks of the customized display case, and are arranged end to end. Their lengths may be cut and angled as desired to further customize the arrangement of the customized display case. Partitions divide different temperature-controlled zones within the display case, and may be positioned anywhere along the length of the case, according to the specific arrangement and lengths of hot, cold, and dry (ambient temperature) zones employed, without regard to the ends of the case or the location of joints separating each of the bed sections.

Claims

1. A modular case for displaying food or the like, comprising:

a bed section having a first length and having first and second ends;

a first zone having a variable second length;

a second zone having a variable third length, said first and second zones being arranged serially along a longitudinal axis of said bed section and being adapted for maintenance at substantially different temperatures relative to one another said different temperatures maintained constant regardless of the actual size of said variable lengths by providing each said zone with independent temperature control; and

a partition located in said case for dividing said first and second zones;

wherein said partition may be positioned at a location along the length of said bed section axially spaced from said first and second ends, and is adapted to be movable when modification of said second or third lengths is desired.

2. A modular case as recited in claim 1, said case comprising a plurality of said bed sections arranged serially end to end, such that a first end of one bed section abuts a second end of an adjacent bed section at a bed joint, wherein said partition may be positioned at a location axially spaced from said bed joint.

3. A modular case as recited in claim 2, wherein the length of at least one of said bed sections is different than the length of another of said bed sections.

4. A modular case as recited in claim 2, wherein adjoining ends of two adjacent bed sections are cut at predetermined opposing angles to form an angular portion of said case, the degree of angularity of said angular portion being directly related to the size of the predetermined opposing angles.

5. A modular case as recited in claim 2, including a premanufactured corner blank bed section having a predetermined angularity which is interposed between two adjacent bed sections to form an angular portion of said case.

6. A modular case as recited in claim 1, said case comprising a plurality of said bed sections arranged serially end-to-end, such that a first end of one bed section abuts a second end of an adjacent bed section at a bed joint, each of said first and second zones comprising a hot zone, a cold zone, or a room temperature zone.

7. A modular case as recited in claim 6, wherein each of said bed sections comprise a bed floor, a first upstanding wall, and a second upstanding wall, said cold zone further comprising a deck pan elevated a predetermined distance above said bed floor and supported by said first and second walls, such that a space is defined between said deck pan and said bed floor and said deck pan defines a floor of said cold zone upon which items to be displayed may be placed, a front glass enclosing said cold display zone, said space having an air inlet passage located at a forward end thereof and an air outlet passage located at a rearward end thereof, said air outlet passage including at least one deflector vane therein, a fan and a refrigeration coil being located in said space, such that when said fan is actuated, air flows from the fan through the coil, then exits said space through said outlet passage into the cold zone display area, said air being deflected forwardly by said at least one deflector vane across said display zone and back into the coil space through said inlet passage without substantially impacting said front glass, thereby minimizing fogging of the front glass.

8.
