DETAILED DESCRIPTION OF THE INVENTION

(7) Referring now to the drawings in which FIGS. 1-4 represent the preferred embodiment of the present invention showing two wire chafing stands 10 nested together with each wire chafing stand 10 being substantially identical in construction.

(8) Each wire chafing stand 10 of the present invention comprises an upper rim 11 composed of wire rod steel in a closed geometrical configuration having two lateral sides 12 and 12 and two longitudinal sides 14 and 14 adapted for the placement of a chafer containing a food product. The lateral sides 12 and 12 lie substantially transverse to the longitudinal sides 14 and 14 to circumscribe an open substantially rectangular surface area geometry. The upper rim 11 is spaced apart from a lower rim 15. The lower rim 15 has geometry substantially identical to the geometry of the upper rim 11 and includes two lateral sides 16 and 16 and two longitudinal sides 17 and 17, the dimensions of which are proportionally smaller than the lateral and longitudinal dimensions of the upper rim 11.

(9) Each wire chafing stand 10 further comprises a plurality of wire legs 18 joined, preferably by welding, to both the shorter lateral sides 12 and 12 of the upper rim 11 and to the shorter lateral sides 16 and 16 of the lower rim 15 on each opposite side of the chafing stand 10. The plurality of wire legs 18 preferably includes a first pair of wire legs 19 and 20 joined to the lateral side 12 of the upper rim 11 and to the lateral side 16 of the lower rim 15 and a second pair of wire legs 19 and 20 joined to the opposite lateral sides 12, 16 of the upper and lower rims 11 and 15 respectively. The first pair of wire legs 19 and 20 are welded to the upper rim 11 so that each of the welded connection 21 and 22 lies in close proximity to the longitudinal sides 14 and 14 on the lateral side 12 of the upper rim 11 such that a gap or space g is formed between the welded connections on the lateral sides of the upper rim relative to the longitudinal sides respectively corresponding to a distance of above zero and no more than about 1 in dimension to the centerline of the longitudinal sides and preferably less than in dimension. Likewise, the second pair of wire legs 19 and 20 are welded to the upper rim 11 on the opposite lateral side 12 in close proximity to the longitudinal sides 14 and 14 of the upper rim 11.

(10) Each pair of wire legs 19 and 20 and 19 and 20 on each lateral side of the upper rim 11 are preferably interconnected to one another to form handles 23 and 24 to grip the wire chafing stand 10 on each opposite lateral side of the chafing stand 10. The handles 23 and 24 extend outwardly from the welded connections 21, 22 with each of the handles 23, 24 having a straight section 30, 30 lying parallel to the lateral sides 12, 12 of the upper rim 11. The handles 23, 24 may be formed independent of the wire legs or without being interconnected thereto.

(11) The pair of wire legs 19, 20 extend from the lateral side 12 of the upper rim 11 to below the lower rim 16 to form base members 25 and 26. Similarly, the pair of wire legs 19, 20 extend from the lateral side 12 to below the lower rim 16 to form base members 25 and 26. The base members 25, 25 and 26, 26 the wire chafing stand in an upright position above ground. Each base member 25, 26 and 25, 26 on each lateral side is preferably formed by bending the wire legs 19, 20 and 19, 20 below the lower rim 16 and 16, on each lateral side, into a configuration with each base member 25, 26 including two upright wire sections 31, 32 and 37, 38 and each of the base members 25 and 26 into two upright wire sections 31, 32 and 37, 38 respectively. The upright sections 31, 32 of base member 25 are aligned in parallel to one another and the upright sections 37, 38 of base member 26 are aligned in parallel to one another with each upright section 31, 32 and each of the upright sections 37 and 38 being welded a fixed distance apart to the lower rim on the same lateral side. Similarly the upright sections 31, 32 of base member 25 are aligned in parallel to one another and the upright sections 37, 38 of base member 26 are aligned in parallel to one another with each upright section 31, 32 and each of the upright sections 37 and 38 being welded a fixed distance apart to the lower rim 16 on the opposite lateral side of the chafing stand 10. Each base member 25 and 26 also has a straight wire section 33 and 39 interconnecting the two upright sections and lying horizontal to the ground. Similarly, each base member 25 and 26 on the opposite lateral side of the chafing stand includes a straight wire section 33 and 39 interconnecting two upright sections and lying horizontal to the ground. The straight wire sections 33, 39 and 33, 39 of each of the base members 25, 26 and 25, 26 form the support for the stand to rest upon the ground.

(12) An offset 40 is located in each of the upright sections 31, 32, 37 and 38 on one lateral side of the chafing stand and a similar offset 40 located in each of the upright sections 31, 32, 37 and 38 on the opposite lateral side of the chafing stand 10. Each offset may be formed by a bending or crimping operation of the wire leg in which the offset is created to form an indent which will cause a lateral displacement between the longitudinal axis extending through the section of the wire leg above and below the indent. At least one offset is required in each wire leg 18 of the chafing stand 10.

(13) The pair of wire legs 19, 20 and 19, 20 are welded to each lateral side 12 and 12 of the upper rim 11 and to the lateral sides 16, 16 of the lower rim 15 with the pair of wire legs 19, 20 and the pair of wire legs 19, 20 lying in common planes at a common angle a as shown in FIG. 2 with respect to a vertical plane transverse to the upper and lower rims 11 and 15, respectively.

(14) A plurality of wire connectors 44, 45 and 46 are welded to the lower rim 15 in an arrangement with each of the wire connectors 44, 45 and 46 being bent to form depressed intersecting sections 48 and 49 adapted to support chafing fuel heaters (not shown).

(15) FIG. 5 represents an alternative embodiment of the invention with the chafing stand 10 constructed in a manner substantially identical to the construction of the chafing stand 10 in FIG. 1 except with regard to the location at which the wire legs 18 are welded to the longitudinal sides of the upper rim 11. Common reference numbers are used to identify the same elements. In FIG. 5, the gap g formed between each wire leg 19, 19 and 20, 20 with respect to the centerline of the longitudinal sides 14, 14 of the upper rim 11 is less than in dimension.
