Description

Description of the invention

This invention relates to an improved wire heating pad that can be easily stacked 2 by nesting with other wire heating pads of the same design for compact storage and transportation.

A wire warming rack is a device used to hold aluminum cookware and auxiliary heaters to keep warm and reheat precooked food in areas away from the kitchen where it was originally prepared and cooked. The price 70 of transportation from the place of production to the distributor and/or to the retailer is a decisive economic factor in the formation of the price of the wire heating stand.

The warming stand is made as an open structure primarily of steel wire elements having predetermined physical dimensions necessary to accommodate, hold and heat the warming pot on the table when placed thereon. Although the heating pad is light in weight, its 12 physical dimensions occupy a significant volume. Accordingly, in order to minimize the cost of loading and transportation, the heating stand should be designed to allow a large number of stands to be folded into one another into a compact structure in which the nested stands are easily separated from each other for independent use. Also, each stand must function to hold multiple fuel heaters for heating food for the purpose of heating a pan for warming food on the table. To minimize the cost of production, the wire heating stand should be designed for minimum human transportation costs, and the power supply for the fuel heaters for food heating should be integral with the stand structure. A commercially available heating pad is described by the applicant in (US Pat. No. 5,921,513), the disclosure of which includes reference numerals. This heating stand contains separate upper and lower wire rims connected to each other by means of symmetrically placed wire racks in each corner of the stand, which in combination with the upper and lower Ge) construction of the rim provide profile support for the stand. The bottom rim is made with the inclusion of several sections for fuel heaters for heating food.

The wire heating stand of the present invention is preferably constructed using only one wire rim and has at least two support posts extending therefrom. This significantly reduces the cost of production compared to the stand described in US Pat. No. 5,921,513. When the structure is limited to two posts, each of them must extend from the rim on opposite sides of the stand in a configuration that holds the stand parallel to the base and provides sufficient profile support for the stand. Although a rectangular shape is preferred, the lunch can be any desired Ge) shape. The sides of the rim can have handles for manually removing the heating grid from the 3o heating stand. These handles can be made integrally as part of the sides of the rim or separately welded to them. A connecting structure of wire sections is used to overlap the racks to hold fuel heaters for heating food. An alternative embodiment of the present invention uses two wire rims similar in design to the stand described in (US patent "

Mo5,921,513), but with an improved bottom rim design to hold multiple fuel sections - 50 food heating heaters. c The preferred embodiment of the presented invention contains a single rim, mainly rectangular

Of" configuration, which has two sides and two wire racks. Each wire rack has a configuration that forms two straight sections and one lower section. The bottom section can also be divided into several segments, which include, for example, two straight segments and a raised segment. The bottom section holds the stand parallel to the base. The stand also includes a connecting structure of wire sections that is preferably connected to a raised and segment of each wire rack for holding a plurality of fuel heaters for heating food. Wired

Ge») racks are preferably welded to the rim near the sides of the stand and preferably have a branch adjacent to the connection of the wire rack to the rim to facilitate sequential stacking of multiple stands one inside the other to minimize space for loading and transporting a plurality of heating stands. A branch in each rack 20 moves the rack transversely relative to the point of contact with the rim in such a way that the wire racks in one stand for heating can enter a considerable distance into another stand with close placement of the rims of each of them in relation to each other without leading to significant jamming.

The rest of the advantages of the presented invention will become apparent from the following detailed description of the invention with the accompanying drawings, which show:

Now let's turn in detail to Figures 1-3, which represent the preferred embodiment of the corresponding 70 inventive stand 10 for heating. The stand 10 includes only one rim 12, generally rectangular in shape, a handle 14 integrally formed on each opposite side of the rim 12, and two wire posts 15 extending from the rim 12. The rim 12 is preferably made of one solid wire with handles 14 performed in one operation. The design of the heating stand 10 with only one rim and two wire racks on its opposite sides allows the racks to be placed relatively deep when stacking several racks 10 /5 in a stack, thus allowing a larger number of racks to be stacked in a given space for storage and transportation relative to to the number of stands that have the design shown in (US patent Mo5921513). This creates a smaller stack of stands at a given vertical height.

Two wire supports 15 are welded at points 1ba, 16r, 16bs and 164 to the rim 12 on opposite longitudinal sides 13 of the support 10 and can be placed relatively close to each side 17. Each wire 20 support 15 has two straight side sections 18 connected between themselves by the lower section 19. The straight side sections 18 may taper obliquely to the lower section 19, as shown in Figures 1 and 2, or may be perpendicular to it, as shown in the embodiment of Figures 9 and 11. The lower section 19 may be made of three segments 20, 21 and 22, as shown more clearly in Figure 2 with the outer segments 20 and 22 positioned horizontally and coaxially with respect to each other in order to be positioned horizontally with respect to the base and with respect to the intermediate segment 21 raised to a higher level. A connecting wire section structure 24 overlaps each raised segment 21 and has a configuration suitable for holding a plurality of fuel heaters 25 for i) heating food, as shown in Figures 2 and 3. The connecting wire section structure 24 comprises two parallel wire sections of connecting elements 26, each of which is configured with two concave sections 27, in which fuel heaters 25 are installed for heating food, and two straight wire elements 28, parallel to the connecting elements 26 so that one wire element 28 is placed on each on the opposite side of the wire connecting element 26 for reliable retention in the concave sections 27 of the fuel heaters 25 for heating food. Gee!

To facilitate the nesting of a large number of wire supports 10 one into another, each wire stand 15 has a branch 30 located in the straight section 18 just below the welded connecting elements 1ba-164. ise) c5 Branches ZO can be made by bending or pressing, or by stamping in a press to cut the wire post 15 to cause lateral movement at each point of connection between the wire post and the rim 12. The branches 30 allow the wire posts 15 in a single wire stand 10 for heating easily fit into another wire support 10 for heating in such a way that the rims 12 of each support will lie in relative proximity without jamming. As such, each nested wire support 10 can be easily separated from the other. The support sections 18 preferably taper inwards as the wire struts 15 extend downward from the rim 12 to the bottom section 19, although they may be parallel as shown in Figures 9 and 11. Another embodiment of the invention is shown in Figures 4-6, which depends only on the conicity of the side sections 18 of each wire rack 15 to facilitate the nesting of several stands 10. In this embodiment, the wire racks 15 do not have branches 30. Accordingly, the ability to insert one in one - And a large number of stands 10 for heating for this version of the execution primarily depends on the angle of taper of the side sections 18 for the purpose of tight placement of the rims 12. Although in this version of the execution of the stand

Me, 10 will not be nested into each other in the same way as in the execution option from Figures 1-3, this option is much

Ge) is cheaper to produce. In all embodiments, the handles 14 can be separately welded to the rim 12 to further simplify manufacturing, and the wire section connecting structure 32 can be used having two wire connecting elements 33, each having only one concave section 34 for accommodation. fuel heaters 25 for heating food. Moreover, only two straight wire members 35 are needed on opposite sides of the connecting members 33 to provide support for the fuel heaters 25 for heating food; when they are located in the concave area 34. Two straight wire elements C6 are placed parallel to the connecting elements 33 with one wire element 36 located on each opposite side of the wire connecting element 33 for reliable placement of fuel

F) heaters 25 for heating food in concave sections 34. ka Another embodiment of the claimed invention uses a connecting structure of 24 wire sections with

Figure 1 with a heating pad 40 as shown in Figure 7 and otherwise similar in construction to the device disclosed in (U.S. Patent No. 5,921,513). The heating wire stand 40 includes both an upper rim 42 and a lower rim 43 and a number of wire posts 44 extending down to the lower rim 43 to hold the stand 40 parallel to the base. The connecting structure 24 of the wire sections is identical to its copy in the embodiment of Figure 17 for holding several fuel heaters 25 for heating food. Alternatively, the connecting structure 32 of the wire sections, as shown in Figure 4, can be used with a heating pad 40 connected to the lower rim 43, as shown in Figure 8.

Still another embodiment of the invention is shown in Figures 9-11, in which the heating stand 50 is shown as having an upper rim 52 and a lower rim 53 connected together using only two wire posts 54. Each of the wire posts 54 is made of a single solid wire rod in a configuration which forms a lower flat bottom section 55 which passes below the lower rim 53 to hold the stand 50 parallel to the base and two straight, generally vertical sections 56 and 57 connected together by a wire member 58 O- similarly shaped to function as a handle for the heating pad 50.

One of the wire racks 54 is separately shown in an enlarged view in Figure 11. As shown in Figure 10, the stand 50 includes a connecting structure of 24 wire sections connected to its lower rim 53.

The connecting structure 24 of the wire sections is identical to its counterpart as shown in embodiment 7/0 of Figure 1 for holding multiple fuel heaters 25 for heating food. Alternatively, the connecting structure 32 of the wire sections, as shown in the embodiment of Figure 8, can be used with the base 50 for heating.

Figures 12-14 are another alternative embodiment of the connecting structure 60 of wire sections for holding a plurality of fuel heaters 25 for heating food, which use only one connecting wire element 61 to overlap the raised segments 21 of two wire racks 15 as in the embodiment of Figures 1 and several ring-shaped elements 62 welded to the connecting element 61 and curved to form a cup-like shape that will hold the fuel heaters 25 for heating the food, as shown in Figures 13 and 14. This embodiment of the connecting structure 60 wire sections it is possible to replace the connecting structure of the wire sections in any of the other versions of the stand for heating according to the Claimed Invention.
