Abstract

A wire-type heating rack has a closed rectangular upper frame and a similar but smaller wire metal lower frame. The heating racks can be nested such that the straight line sections extending between the upper and lower frames contact each other during nesting and the upper frames of the nested racks are held tightly against each other. The upper and lower rims are connected by at least two wires that are substantially identically shaped and curved, each wire being unitary and having a section thereof attached to the upper rim and extending outwardly therefrom to form a handle element for the wire-type heating rack. Each wire is attached to the lower rim and extends downwardly therefrom to form two support legs for the linear heating rack.

Description

Wire type heating rack capable of being compactly stacked

Technical Field

The present invention relates to an economical, easily constructed linear heating rack that also enables very compact nesting and stacking, compact storage and maximum stability.

Background

The heating body and the heating frame are used for holding the plate, and the heating device is usually held below the plate. Catering establishments and restaurants often use such devices while keeping food warm at a location (rather than at the point where the food was initially prepared). For example, heating bodies are used in places such as banquet halls, where large quantities of food are always supplied directly.

The heating body usually takes the form of a rectangular metal container, having generally standard dimensions, and is filled with the food to be heated and/or served. The heating body is usually supported during heating and supply on movable linear carriages, each of which is hereinafter referred to as "linear heating carriage" and is often made of steel. The prior art linear heating rack, as exemplified in U.S. patent 5,921,513 filed by Robert skvorez, is a relatively simple structure having an upper rim and a lower rim formed by respective larger and smaller rectangular wire structures surrounding respective rectangular openings. The upper and lower frames are connected to each other by legs to form a truncated cone structure, which retains and supports the heating body having the food contained therein in specification. The legs are often welded to the upper and lower rims at the corners of the structure, with the legs extending below the lower rim so that they also serve as bottom supports to maintain the height of the rack relative to the ground and to maintain the lower rim at a predetermined height above the ground to position the heating fuel heater for use in a heating dish in the rack.

Since a plurality of heating bodies are sometimes used as needed, a plurality of linear heating racks are also required, and the heating bodies and the linear heating racks are separately transported and stored and stacked together in a plurality of units. Currently, linear heating racks, such as those shown and described in the aforementioned patents, allow the racks to partially nest with one another when stacked (i.e., when the racks nest together), but only to a limited extent. As further described in said patent, the costs of storage and transport are directly related to the vertical height of the stack of nested wire frames. Thus, for line frames having only limited nesting capabilities, the transportation costs for transporting such line frames over long distances become considerable in their sales price. This in turn reduces competitiveness in geographically large areas where transportation and/or storage costs become prohibitive.

In describing the linear frame structure of the heating body of the prior art, further attention is paid to: a structure that allows the nesting of multiple shelves to reduce the height of the vertical column in which the shelves are stacked, almost always entails various drawbacks. These disadvantages include: complex linear rack designs, which additionally increase manufacturing costs and result in the rack being structurally and aesthetically bulky.

One particular problem in the prior art is: it is difficult to remove the nested linear frames from each other. Generally, if the linear strands are securely nested, they tend to wedge into each other and are thus difficult to separate. The heating racks must be easily separable from each other, so that deep nesting is particularly avoided when the construction of the linear heating racks is generally considered.

Accordingly, there is a need in the art to provide a wire-type heating rack having improved nesting capabilities, less storage footprint, simpler manufacturing, and lower implementation costs.

Disclosure of Invention

The present application relates to a linear rack for heating or a linear heating rack capable of achieving deep nesting of a plurality of racks to minimize the size of stacking the racks. This allows the stacking height of a plurality of such shelves to be significantly less than the stacking height of the prior art without the structural complexity and expense problems mentioned in the prior art.

Detailed Description

The present application relates to a linear rack for heating or a linear heating rack capable of achieving deep nesting of a plurality of racks to minimize the size of stacking the racks.

Referring to the drawings, FIGS. 1-4 show a single linear heating block 10 of the embodiment described herein, including an upper line frame 20 and a smaller lower line frame 30, the lower line frame 30 being separate from the upper line frame 20 and positioned relative to each in a standard heat retention position. The upper and lower line frames 20, 30 form a generally rectangular closed configuration and have generally the same rectangular geometry (aspect ratio) of different dimensions.

The top border 20 includes a pair of long end sides 21, 23 and a pair of short end sides 22, 24. Similarly, downline border 30 includes: a pair of long end sides 31, 33 disposed generally below the long end sides 21, 23, and a pair of short end sides 32, 34 disposed generally below the short end sides 22, 24. The lower rectangular line frame 30 additionally includes: a longitudinal section 81 connecting the

short sides

32, 34, and a pair of

lateral sections

82, 83 connecting the

long sides

31, 33. In some embodiments, the

sections

81, 83 are symmetrically spaced relative to the

short sides

32, 34, with each

section

81, 83 being disposed about 1/4 the length of the

long sides

31, 33 from the corresponding

short side

32, 34. In some embodiments, the longitudinal section 81 comprises: a pair of sunken sections disposed below the plane of the lower rim 30, each sunken section being received in a corresponding sunken section formed in one of the two

sections

82, 83, thereby defining a pair of heating member seats in the bottom portion of the heating rack 10.

Curved integral lines 40 and 40' of the same size and shape are attached to the pairs of short end sides 22, 32 and 24, 34 of the rectangular upper and lower side frames 20, 30, respectively, and form

respective handles

45 and 46, pairs of

support legs

41, 42 and 43, 44, as described below. The paired

sections

91, 92 and 93, 94 of the wires 40 and 40' are straight sections that are attached at

bends

51, 52 and 53, 54, respectively, to the

long sides

21, 23 of the superior border 20 and to the

long sides

31, 33, respectively, of the inferior border 30, whereby they separate and hold the superior and

inferior borders

20, 30 with their respective long sides in a fixed position relative to each other.

The paired

straight line sections

95, 96 and 97, 98 of the lines 40 and 40' are attached to the short end side edges 22, 24 of the upper line border 20 at

locations

55, 56 and 57, 58, respectively, and to the short end side edges 32, 34 of the lower line border 30, respectively, whereby they separate and hold the upper and lower line borders 20, 30 with their respective short sides in fixed positions relative to each other. Thus, each of the lines 40 and 40' has four sections that extend between and are connected to the upper and

lower borders

20 and 30, thereby maintaining the upper and lower borders in a fixed position relative to each other.

The

curved line sections

45 and 46 are defined between respective pairs of

lines

95, 96 and 97, 98 of lines 40 and 40', are attached to the short end side edges 22 and 24 of the upper rim 20, respectively, and extend away from the side edges 22 and 24 at right angles to form lifting handles 45, 46 for the line-type heating rack 10. In some embodiments, the

handles

45, 46 are welded to the underside of the short end sides 22, 24.

Pairs of

curved line sections

41, 42 and 43, 44 defining support legs extend below the lower rim 30 at the

lower rim corners

36, 37 and 38, 39 respectively and are curved outwardly as shown to form respective support legs. It will be appreciated that in the illustrated embodiment the support legs form a quadrilateral, however, a triangle is also possible if the wire is able to accommodate bending stresses, which would reduce one bend.

As shown in fig. 1 and more clearly seen in fig. 7 and 8, the wire 40' (which is identical to the wire 40) implements 14 bends (or twists) a-n to provide the

respective legs

43 and 44, the handle 46, and the pairs of

support sections

93, 94 and 97, 98 between the upper and lower side frames 20, 30. As can be seen in fig. 3 and 4, the curved lines 40 and 40' (and the associated upper and lower borders 20 and 30) are symmetrical with respect to a vertical axis along the short end of the rack 10 and along the long end of the rack 10 so that the linear heating rack 10 can be easily nested, as shown in fig. 6, regardless of end or side orientation.

Fig. 5 illustrates a case in which 20 linear heating racks as disclosed in the aforementioned patent are stacked as a stack 60 in the prior art. In contrast, the linear heating rack 10 disclosed herein is shown in fig. 6 as similarly stacked in the same stack of 20 units. The height of the stack 60 is shown as height 61, with a single stack height of 61'. The stack 70 of the present invention has a stack height 71 that is less than 70% of the prior art stack height 61 and the individual stack height 71 'is less than 60% of the prior art individual stack height 61'. As is apparent in fig. 6, the various sections and elements of the internal bend line structure of the leg, handle, bezel separation section are closely arranged in a stack 70, wherein the large obtuse angle bend of the line enables an easily separable wire form frame without wedging.

Fig. 7 to 10 illustrate views of the shaped and bent wire 40' of the described embodiment, clearly showing each of the angled bends of 90 ° or greater, which provides an anti-wedging effect when the wire type heating racks are deeply nested. It should be appreciated that since wires 40 and 40 'are identically shaped, all descriptions of wire 40' apply equally to wire 40.

As shown in fig. 7-10, respectively, the shaped and bent wire 40' is unitary, or formed from a single piece of wire, and is shaped and configured to be attached to one side of vertically adjacent upper and lower rectangular bezels 20 and 30 (visible in fig. 1-4). Corresponding identically shaped wires 40 are configured to be attached to opposite sides of vertically adjacent upper and lower

rectangular borders

20 and 30. Each integral line 40, 40 'has reflective symmetry, also known as mirror symmetry, on both sides of a vertical axis V (as shown in fig. 10) that extends through the center of the integral elongate line 40' and is perpendicular to a horizontal portion of the line, such as the handle 46 of the line.

The wire is symmetrically curved along its length on both sides of a vertical axis V shown in fig. 10, including a plurality of bends or twists, labeled a-n. Particular features taught herein are: each bend a-n comprises only an obtuse angle of not less than 90 deg., thereby preventing wedging of the heating block when nested.

Turning to the specific bends, it is visible: the wire 40 'includes short lateral twists a formed successively from one end, which are configured such that the wire 40' is attached to the long end side of the upper frame 20. Extending downward at an angle therefrom are: a first inclined long end side straight line section 93 extending toward the proximal vertically adjacent corner 38 of the lower bezel 30 to effect attachment between the end of section 93 and the lower bezel 30. The continuous offset oblique bend b lies out of the plane of the line, providing a first side b-c of the support leg 43. The bend c is lateral to the first side of the support leg 43 providing a base c-d for the support leg 43.

The upwardly bent portion d is directed toward the distal side of the vertically adjacent corner 39, defines a second side d-e of the support leg 43 providing a leg quadrilateral, and enables attachment between the second side d-e of the support leg 43 and the lower rim 30. A further bent portion e is located in the vicinity of the attachment portion between the second side of the support leg 43 and the lower bezel 30, and a first inclined short-end side linear region 97 is provided, the first inclined short-end side linear region 97 being inclined in an upward direction away from the support leg 43 and away from the start line end and toward the second short-end side of the upper bezel 20, configured to attach the region 97 to the upper bezel 20. A laterally outwardly bent portion f from the attachment area between section 97 and upper rim 20 forms a first leg f-g of handle member 46. The wire is then bent at g, this bend being configured parallel to the second end side 24 of the upper rim 20 to form a first half of the gripping portion of the handle 46 at the vertical axis V (fig. 10) and the midpoint and half of the elongated wire 40'.

The mirror-symmetrical configuration of the other half of line 40' is provided successively from the line midpoint at axis V, through the bends and twists h-n: the second half of the handle 46, the second short end side straight line section 98, the second support leg 44, and the second long end side straight line section 94.

The lines 40 and 40' are identical and symmetrical along a vertical axis V (fig. 10) and thus can be used on either side of the vertically stacked upper and

lower bezels

20 and 30 and can be closely nested without wedging, with the legs, handles, angled sections fitting closely to each other as shown in fig. 6 to provide a minimum sized stacked structure suitable for economical transport and use.

Although the disclosed technology has been taught with specific reference to the above embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the disclosed technology. The described embodiments are to be considered in all respects only as illustrative and not restrictive. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.

Combinations of any of the methods, systems and devices described herein above are also contemplated and are within the scope of the invention.
