Description

  The present invention relates to charcoal combustion technology, and more particularly to a folding cooking stand.

  The structure of the cooking stand disclosed in Patent Document 1 is divided into a portion that cannot be folded and a portion that can be folded.

  The portion of the cooking stand that cannot be folded is an annular piece that cannot be folded together. During use, the ring piece blocks the area around the charcoal, so that the flame that burns the charcoal can be prevented from disappearing even when strong wind blows. However, when it was not used, it had to be laminated on the article and occupied space wastefully.

  A folding stand that can be folded connects two or three bent plates together using a large number of hinge structures, and is enclosed together to form a cooking stand space like a square tube. The curved plates are convexly curved, but cannot be folded by interfering with each other. Therefore, when storing, the independent curved plates could not be stacked unless all the hinge structures were removed. Thus, the conventional cooking stand is not only very troublesome to store, but also complicated to assemble.

  The folding cooking stand disclosed in Patent Document 2 is formed in a square tube, a triangular tube, or the like, respectively.

  The rectangular cylindrical cooking stand has two wide surface plates and four narrow surface plates, and is connected to each other by six hinge structures to form four sides. Each side may be a wide face plate or a pair of narrow face plates connected to each other. When two pairs of narrow plates are folded so as to face each other, the two wide plates collapse so that they face each other, the cooking stand changes from a square tube to a flat shape and can be easily stored, but there are many disadvantages There was, and the difficulty of assembly was high.

  The triangular cylindrical cooking stand has a hinge structure composed of one large and three small. The large hinge structure connects two wide surface plates, and the small hinge structure is connected between two narrow surface plates or between the wide surface plate and the narrow surface plate, and is an equilateral triangular cylindrical cooking stand. Configure.

  When storing, the cooking stand can be changed from a triangular tube to a flat shape by stacking two narrow plates toward a large hinge structure and tilting the two wide plates so as to face each other. However, since the volume of the hinge structure is different, the small hinge structure cannot be brought close to the large hinge structure, and when the large hinge structure is brought close to the small hinge structure, the cooking stand should be in a flat storage state. I couldn't.

  Therefore, there has been a demand for a technique for improving the disadvantages of folding a conventional hinged cooking stand.

  The folding stand according to the present invention has a volume of the hinge structure different when the cooking stand is folded by folding the sub-plate with respect to the main plate to leave a storage space for the hinge structure. Conventional problems that could not be brought close to each other can be improved.

FIG. 1 is an exploded perspective view illustrating a folding cooking stand according to an embodiment of the present invention. FIG. 2 is a plan view showing a state when a folding cooking stand according to an embodiment of the present invention is joined and opened. FIG. 3 is a perspective view showing a state in which a folding cooking stand according to an embodiment of the present invention is unfolded. 4 is a cross-sectional perspective view taken along line AA of FIG. FIG. 5 is a top view of FIG. FIG. 6 is a plan view showing a state in which a foldable cooking stand according to an embodiment of the present invention is folded.

  Please refer to FIG. 1 and FIG. As shown in FIGS. 1 and 2, a folding cooking stand according to an embodiment of the present invention includes at least a first joining plate 12, a second joining plate 14, a plurality of hinge structures 20, and a wide surface plate. 30 and the narrow plate 40.

  Each hinge structure 20 includes a combination of two rows of short tubes 21 and pins 23. The short tubes 21 in each row are formed on the sides of the first bonding plate 12 and the second bonding plate 14, the wide surface plate 30 and the narrow surface plate 40, and pins 23 are connected to the intersecting two rows of short tubes 21. The hinge structure 20 is configured to be inserted and turnable with a certain width. Since the diameter of each short tube 21 of this embodiment is the same, the volume of each hinge structure 20 is equal.

  The wide plate 30 is divided into two parts, a main plate 32 and a sub plate 34. The main plate 32 has an area substantially equal to the area of the first bonding plate 12 or the second bonding plate 14, and one side is connected to the side corresponding to the first bonding plate 12 via the hinge structure 20. The sub plate 34 is bent with respect to the main plate 32, and the main plate 32 and the sub plate 34 form a bending angle 36 (see FIG. 5). Further, the sub plate 34 and the first bonding plate 12 are not located on the same side of the main plate 32.

  The narrow surface plate 40 has one side connected to the second bonding plate 14 via the hinge structure 20 and the other side connected to the sub plate 34, and the total area of the narrow surface plate 40 and the sub plate 34 is the first bonding plate. 12 or approximately the area of the second bonding plate 14.

  In the present embodiment, each of the first bonding plate 12, the second bonding plate 14, the wide surface plate 30, and the narrow surface plate 40 is a stepped metal plate. For example, the narrow plate 40 has a long side 42 and a short side 44. The long side 42 and the short side 44 are substantially parallel. The narrow plate 40 has two hypotenuses 46. The oblique side 46 is connected to both ends of the long side 42 and the short side 44, respectively. Therefore, the cooking stand 10 exhibits a shape that spreads like a fan.

  Subsequently, the first bonding plate 12, the second bonding plate 14, the wide surface plate 30 and the narrow surface plate 40 have two circular holes 16, respectively. The circular hole 16 is adjacent to the short side 44. The second joining plate 14, the wide surface plate 30 and the narrow surface plate 40 have a plurality of support portions 22 in addition to the two long holes 18. Each support portion 22 may be a lateral plate 24 (for example, the second bonding plate 14 and the narrow surface plate 40) or a flexible plate 26 (for example, the wide surface plate 30).

  Please refer to FIG. As shown in FIGS. 3 to 5, the deployed angle 11 is formed by the first joining plate 12 and the second joining plate 14 at the deployed position. The shape of the cooking stand 10 is similar to a quadrangular pyramid cylinder, and the development angle 11 and the bending angle 36 are in a diagonal relationship. The deployment angle 11 is 90 ° ± 5 ° and is substantially equal to the bending angle 36.

  At this time, the second bonding plate 14 faces the wide surface plate 30, and the lateral surface plate 24 and the flexible plate 26 form a pair. Further, the narrow surface plate 40 obtains an auxiliary action through the lateral surface plate 24, supports the charcoal fire plate 50, is placed on the cooking stand 10 where the charcoal fire plate 50 is deployed, and is suspended in the air.

  The main plate 32 is provided with two pivot portions 28 so that a handle (not shown) can be connected.

  Please refer to FIG. As shown in FIG. 6, when the narrow plate 40 and the main plate 32 are tilted so as to face each other in the folding position, the first bonding plate 12 and the second bonding plate 14 are brought together, and the main plate 32 and the sub plate Since the hinge structure 20 between the first joining plate 12 and the second joining plate 14 is accommodated in the bent portion 34, the operation of the hinge structure 20 is prevented between the sub plate 34 and the narrow surface plate 40. There is nothing.
