Linear heating rack capable of compact stacking

Abstract

A wire type heating rack having a closed rectangular upper frame and a similar but smaller shaped wire metal lower frame. The heating frames can be nested, so that the straight line sections extending between the upper and lower frames contact each other when they are nested, and the upper frames of the stacked frames are closely held to each other. The upper and lower frames are connected by at least two substantially identically shaped and bent wires, each of which is integral and has a section thereof attached to the upper frame and extending outwardly therefrom to form a handle element for Linear heating rack. Each wire is attached to the lower frame and extends downwardly therefrom to form two support legs for the wire heating rack.

Description

technical field [0001] The present invention relates to an economical, easy-to-build wire-type heating rack that also nests and stacks very compactly for compact storage and maximum stability. Background technique [0002] The heating body and the heating rack are used to hold the pan, and often the heating device below the pan. Catering establishments and restaurants often use such devices when keeping food warm at a location other than where the food is initially prepared. For example, heating bodies are used in places such as banquet halls, where large quantities of food are always served directly. [0003] The heating body is often in the form of a rectangular metal container, generally of standard size, and filled with food to be heated and / or served. The heating body is usually supported during heating and supply on movable wire frames, each of which is hereinafter referred to as a "wire heating frame" and is usually made of steel. Prior art wire-type heating racks,...

Problems solved by technology

This in turn reduces competitiveness in geographically large areas where transportation costs and / or storage costs become prohibitive

[0005] When describing the linear frame structure of the heating body in the prior art, it is further noted that the structure that allows multiple frames to be stacked to reduce the height of the vertical column of each frame stacked by the stack almost always brings various disadvantages

These disadvantages include: complex wire frame design, which additionally increases manufacturing costs and makes the frame structurally and aesthetically bulky

[0006] A special problem in the prior art is that it is difficult to dismantle the stacked wire frames from each other
