Description

  The present invention relates to a bonfire that can be folded and transported easily.

  As human recreational activities become popular, the act of cooking outdoors is becoming more common. At that time, from the viewpoint of environmental beautification, it has become common not to carry out an open fire, and at the same time, as its diversity increases, the demand for firebeds that are particularly light and have a small storage volume is increasing. Conventionally, so-called barbecue firebeds have had high rigidity using iron or stainless steel and nets using metal wires, but there have been problems with weight and volume during transportation. It can still be accepted when transported by a car, but it can be said that there was no light and small folding volume that can be carried in a small bag. The present invention provides a technique for using a flexible fire bed having high heat resistance and stably supporting the fire bed with high strength.

  The problem to be solved is to provide a structure in which a woven fabric of silica fiber mainly composed of quartz having a high melting point is suspended and folded without damaging the strength of the woven fabric. . However, the present invention is not limited to silica fiber, and any material may be used as long as it has heat resistance that can withstand direct fire and has a flexible property that can be folded.

  FIG. 1 briefly shows one of the main structures of the present invention. A cloth woven from a fiber having high heat resistance such as silica, that is, a flexible fire floor surface 1 is wound around a hollow holding cylinder 3 made of a metal such as aluminum without making a hole in the woven cloth, and is sewn. The four corners of the suspension wire 4 made of stainless steel or the like passed through the hollow holding cylinder 3 are hooked and held on the support base 2.

  Fire or charcoal is placed on the flexible firebed surface 1 to burn the fire, but the weight of the firewood and charcoal works in the direction of expanding the support base 2, so that the entire structure does not collapse and has a stable structure. keep. Moreover, since the four sides containing the holding cylinder 3 are held at the same height, ash, firewood, small pieces of charcoal, etc. generated on the flexible fired floor surface body 1 will fly into a wind of considerable strength. It stays without. The effect is that the four sides are held at the same height.

  Further, the flexible fire bed planar body 1 is made of silica fiber having low thermal conductivity, and at the same time, the fire bed and the support base 2 are in contact with each other only by the suspension wire 4 and heat conduction hardly occurs, and the temperature of the support base 2 is increased. Is kept low. As a result, the cooling time after use is short and there is little trouble of storing. A barbecue or the like using a general firebed mainly composed of metal is advantageous also in this respect because it takes time to store it after use.

  FIG. 1 is a block diagram showing one specific overall image of the present invention, which is composed of main parts of a flexible firebed surface 1, a support base 2, a holding cylinder 3 and a suspension line 4.

  In particular, a fabric woven from a fine silica wire composed mainly of pure quartz, that is, a flexible fired floor 1 made of silica fiber, has high heat resistance, but is not necessarily strong against partial mechanical stress concentration and is damaged. Easy to tear. Accordingly, it is important to have a structure that holds the easily-breakable flexible firebed 1 without making a hole that easily causes mechanical stress concentration. As shown in FIG. 2, the present invention has a hollow cylinder made of metal such as aluminum having high rigidity. By using the holding cylinder 3, this problem was solved.

  That is, the flexible fire floor planar body 1 is wound around the holding cylinder 3 and folded, and the folded portion is sewn with a sewing fiber 5 which is also highly heat-resistant silica fiber or stainless steel fiber having high heat resistance. Since the holding cylinder 3 is individually attached to each side of the flexible firebed planar body 1 and is connected by a flexible suspension line, the following effects can be exhibited without impairing the foldability of the firebed. It becomes possible.

  Without this holding cylinder 3, not only the suspension wire 4 made of stainless steel directly hits and rubs against the flexible fired floor surface body 1, but also the four sides are curved, and charcoal and firewood easily spill out to the outside. is there. Further, by connecting the fire bed surface 1 and the support base 2 with the suspension line 4, it becomes possible to reduce the thermal conductivity of each other, preventing the support base from being deformed and altered, and further after use. This produces the effect of shortening the cooling time.

  Further, as shown in FIG. 3, the corners of the flexible fire floor planar body 1 are caulked with a caulking part 6 made of a rigid metal, and the caulking part 6 is caught and fixed to the support base 2. In the case of this structure, since the sewing work can be omitted, the manufacturing process can be simplified. However, the tensile resistance may be slightly reduced as compared with the folded structure shown in FIG.

  The flexible fired floor planar body 1 such as silica fiber is generally vulnerable to scratches, but if an appropriate diameter and processing step are selected, as shown in FIG. 4, a eyelet is provided in the corner and pulled through the suspension line 4. You can also do things. Also in this case, since the sewing process shown in FIG. 12 can be omitted, the productivity is improved, but it is necessary to appropriately select the perforation to the flexible firebed surface body 1 and the strength to crimp the eyelets. If the strength is too strong, the mechanical strength of the portion where the eyelet compresses the flexible fired floor surface body 1 decreases, and if it is too weak, a large tensile stress is generated in a part of the flexible firebed surface body 1 and the mechanical strength is increased. Strength decreases.

  In the case of Examples 1 and 2, the suspension line 4 is used. However, since the suspension line 4 passes through the hollow holding cylinder 3, a part of the ring needs to be cut. After passing through the holding cylinder 3, as shown in FIG. 5, it is fixed with male and female screws connected to both ends of the suspension line 4. Alternatively, both ends of the suspension line 4 are ring-shaped, and are connected by a detachable connection ring 10. Since the strength of the flexible firebed surface body 1 deteriorates with long-term use, such a structure that can be easily removed is important in order to easily replace the worn flexible firebed surface body 1. .

  The support base 2 for fixing the suspension line 4 for suspending the flexible fire floor surface body 1 also needs to be folded, and its function is realized as a structure that can be folded and disassembled as shown in FIG. The disassembled support base is deformed and folded by the folding rotation shaft 11, and the storage size can be reduced.

  As a result, a folded shape as shown in FIG. 7 can be realized. When the dimensions of the suspension line 4 in use are 40 cm × 40 cm, the height of the support base is 28 cm, and the thickness of the flexible firebed 1 is about 5 mm, it can be completely accommodated in a cylindrical tube having a length of 35 cm and a diameter of 9 cm. I can do it. In this case, the weight could be reduced to about 1 kg.

  As described above, as another embodiment of the present invention, the suspension structure using the flexible suspension line 4 has been shown. However, a structure using the integral frame 9 which is a rigid body as shown in FIG. Even in this case, the structure of folding and winding shown in FIG. 2, the structure using caulking shown in FIG. 3, and the method using the eyelet shown in FIG. 4 can be used.

  As described above, as another embodiment of the present invention, a cloth woven with silica fibers such as quartz is used for the flexible firebed 1, but it is also possible to use a net of fine metal wires. In this case, since the fire directly heats the fine metal wire, it is necessary to use a stainless steel, which is constantly used for a long time and has a higher heat resistance, such as a nichrome wire.

  Furthermore, as another embodiment of the present invention, in order to reinforce the flexible fire bed surface body 1 having relatively low mechanical strength, a structure backed with a metal net or another non-combustible cloth is provided. In this case, since the mechanical strength can be imparted to a metal net or a non-combustible cloth, a cloth woven with silica fibers such as quartz can be thinned, and heavier charcoal or firewood can be placed thereon.

  Since the silica fiber used in the present invention is sufficiently thick so that heat is not transmitted violently below, the non-combustible fabric does not need the heat resistance as the silica fiber, and has the purpose of mainly increasing the mechanical strength. In practice, non-combustible curtain fabrics can also be used.

  In this case, either the suspension structure using the flexible suspension line 4 shown in FIG. 1 or the structure using a rigid body as shown in FIG. 8 can be used, and the structure shown in FIG. The structure using the caulking shown in FIG. 3 and the method using the eyelet shown in FIG. 4 can be used.

  Moreover, although the continuous body of the stainless steel wire was used for the suspension wire 4 as description of the above this invention, even if it uses a chain | strand, this invention can be implemented similarly.

  Although the main structure of the present invention has been described above, in addition to the feature of being small and foldable and light, it is also possible to place a kettle, a pan, or a rice bowl on which five virtues as shown in FIG. 9 are placed. In this case, if the virtues are removed during use, a very dangerous state is assumed. Therefore, as shown in FIGS. 10 and 11, a structure that can be temporarily fixed to the support base 2 is indispensable.

  That is, as shown in FIG. 10, a fixing hole 21 for fixing the virtues is provided at the tip of the support base, and a fixing protrusion 22 is provided at the tip of the virtues, and the constricted portion of the fixing protrusion 22 is connected to the fixing hole 21. Do not get caught by the edge.

  Moreover, as shown in FIG. 11, if it fixes with the fixing screw 23 through the fixing hole 21 and the hole provided in the front-end | tip of the virtues, although the effort of attachment / detachment will arise, it is still safer.

  In addition, skewers can be made by placing a skewer stand 31 as shown in FIG.

  As described above, the embodiment of the present invention has shown an example using a substantially square flexible fire bed surface. However, depending on the purpose of use, an elongated rectangle, or a triangle or a polygon having five or more sides may be suitable. Similarly, the present invention can be applied. For example, a rectangle is convenient for barbecues where many skewers are laid out side by side.

  Among the polygons, the triangle has the feature that the support base is the smallest and lightest, and is particularly suitable for reducing the weight. In addition, if the surface on which the support base is placed is uneven, one side of the quadrilateral may float in the air and become unstable, but the apex of the triangle forms a plane, so the support base is placed. The surface does not necessarily need to be a flat surface, and the support is stable.

  The pentagonal or more polygonal shape increases the rigidity of the entire support base, which is advantageous not only for placing heavy combustibles, but also because there are few protruding parts at the end of the flexible firebed surface, It is excellent in that the area of the floor surface is effectively used.

  In addition, in the case of a polygon including a square, it is not necessary to match the number of sides and the number of legs of the support base, and a triangular flexible fire bed surface may be placed on the legs of the six support bases. It is also possible to place an octagonal flexible fire bed surface on a rectangular support. What is necessary is just to select suitably the shape of a flexible fire bed planar body, and the number of legs of a support stand according to a use.

  As mentioned above, the present invention has been used as one of the so-called camping supplies. However, if the advantage of being portable and easily ignited is used, it can be used for applications that require heat of about several hundred degrees Celsius outdoors. it can. For example, there is a bonfire that heats a grilled iron imprinted on livestock, and a bonfire that burns a soldering iron in the outdoors without electricity.
