Description

The present invention relates to a foldable bonfire.

Traditionally, in camping, mountain climbing, etc., various types of bonfires have been used to heat or warm cooked foods such as foodstuffs and beverages. In addition to the weight of cooking utensils and cooking utensils placed on the bonfire, the weight of the bonfires such as the trivet and rostrum and the weight of fuel materials such as firewood and charcoal are added to these bonfires. It is required to have sufficient strength to support the total weight of the bonfire, and it is also required to be convenient to carry and to accommodate when not in use. Therefore, many bonfires are designed as foldable bonfires that are strong enough when in use, foldable when not in use, and are convenient to carry.

For example, Patent Document 1 proposes a foldable bonfire capable of stacking and folding each member such as a bottom plate and a side plate constituting the bonfire. In this foldable bonfire, each member is made of a relatively thick metal plate so that it can withstand a load from above and repeated use, etc., and it has the necessary and sufficient strength. There is. However, on the other hand, since each member was composed of a thick metal plate, the weight increased, and it could not be said that the bonfire was suitable for carrying.

The method of connecting the first side plate plate 10, the second side plate plate 20, the fire bed plate 30, the first leg member 40, and the second leg member 50 has been described above. Next, the folding and using of the foldable bonfire 1 will be described below.

As shown in FIGS. 11 to 16, the foldable bonfire 1 has a first side plate plate 10, a second side plate plate 20, a fire bed plate 30, a first leg member 40, and a second leg member 50 when not in use. Each is overlaid and folded in a closed state. At this time, a fire bed plate 30 is sandwiched between the first side plate plate 10 and the second side plate plate 20, and the fire bed plate 30 is connected to the first side plate plate 10. It is folded with the connecting protrusions 31 and 31 on the lower side and the fire bed plate locking protrusion 32 locked on the second side plate plate 20 on the upper side. Further, the first leg member 40 and the second leg member 50 are also closed along the first side plate plate 10 and the second side plate plate 20 without making an angle to the first side plate plate 10 and the second side plate plate 20, respectively. It is folded in the folded state.

In the foldable bonfire 1, as shown in FIGS. 1 and 6 to 10, when used, the first side plate plate 10 and the second side plate plate 20 connected via the connecting portion 2 form the connecting portion 2. A fire bed plate 30 is bridged between the first side plate plate 10 and the second side plate plate 20 which are relatively opened as a shaft and in this relatively opened state. Specifically, the first side plate plate 10 and the second side plate plate 20 in the opened state have a substantially semicircular second side plate plate lower end portion 21 that draws an arc of the second side plate plate 20 as the first side plate. While being pushed into the flat plate portion of the plate 10, the slit portions 13 and 13 at both ends and the protrusions 23 and 23 at both ends of the connecting portion 2 repel the pushing of the lower end portion 21 of the second side plate plate, and the rigidity of the plate is increased. By pulling each other with each other, the vicinity of the center extending from the upper end to the lower end of the first side plate plate 10 and the second side plate plate 20 bends in a concave shape to form a substantially eaves gutter-shaped side plate. From above the gutter-shaped side plate, the fire bed plate 30 hinged with the first side plate plate 10 is bridged to the second side plate plate 20. At this time, the fire bed plate 30 has a rigidity force for the first side plate plate 10 and the second side plate plate 20 to return from a substantially eaves girder shape to a substantially flat plate shape and a rigidity for returning from an open state to a closed state. Since the bridge is bridged against the force, the fire floor plate locking protrusion 32 of the fire floor plate 30 is provided with the fire floor plate locking slit of the second side plate plate 20 so that the bridged state can be maintained. It is inserted into 25 and locked. As a result, the first side plate plate 10, the second side plate plate 20, and the fire bed plate 30 are firmly supported by each other. Further, the first side plate plate 10 and the second side plate plate 20 are kept in an open state while forming a substantially eaves gutter-shaped side plate.

Further, as shown in FIGS. 1 and 6 to 10, when the foldable bonfire 1 is used, the first side plate plate 10 and the second side plate plate 20 in the opened state are the first side plate plate 10 and the first side plate plate 20. It becomes self-supporting by being supported by the first leg member 40 and the second leg member 50 which are locked to each of the two side plate plates 20 at an angle. Specifically, as shown in FIG. 17, in the first side plate plate 10 in the closed state, the protrusions 42, 42 for locking the first side plate plate of the first leg member 40 are formed on the first side plate plate 10. The first side plate plate 10 in a state where the first leg member locking slits 17 and 17 are inserted and locked and the first leg member locking slits 17 and 17 are locked is opened as described above. In this state, as shown in FIGS. 1 and 6 to 10, the first leg member 40 is held at an angle to the first side plate plate 10. Further, similarly to the first leg member 40 shown in FIG. 17, in the second side plate plate 20 in the closed state, the second side plate plate locking protrusions 52, 52 of the second leg member 50 are second. The second side plate plate 20 in a state where the side plate plate 20 is inserted into and locked into the second leg member locking slits 27 and 27 and the second leg member locking slits 27 and 27 are locked is described above. By being in the opened state, the second leg member 50 is kept at an angle to the second side plate plate 20 as shown in FIGS. 1 and 6 to 10. As a result, in the foldable bonfire 1, the first side plate plate 10 and the second side plate plate 20 in the opened state are supported by the first leg member 40 and the second leg member 50 and become self-supporting. It is preferable that each of the first leg member 40 and the second leg member 50 is configured to bend in a state of being locked to the first side plate plate 10 and the second side plate plate 20. Due to this bending, it is possible to make a cooking fire stand stronger against a load from above.

As described above, this embodiment is configured. Next, the effect of this embodiment will be described.

As described above, the foldable bonfire 1 of the present embodiment has a first side plate plate 10, a second side plate plate 20 connected to the first side plate plate 10 by a connecting portion 2, and a hinge shape to the first side plate plate 10. The first side plate plate 10 and the second side plate plate 20 are overlapped with each other and closed with the fire floor plate 30 sandwiched between them at the time of folding. The plate 10 and the second side plate plate 20 are opened in a substantially V shape with the connecting portion 2 as an axis, and the fire bed plate 30 is locked to the second side plate plate 20, and the first side plate plate 10 and the second side plate plate 20 are engaged. It will be bridged over 20. That is, in the foldable bonfire 1, when not in use, the first side plate plate 10 and the second side plate plate 20 are folded with the fire floor plate 30 sandwiched between them, so that they are easy to carry and store, and when in use, they are easy to carry and store. , The first side plate plate 10 and the second side plate plate 20 are opened in a substantially V shape with the connecting portion 2 as an axis, and the fire bed plate 30 straddles between the first side plate plate 10 and the second side plate plate 20. Can be used as a bonfire with an open upper part in a state where the first side plate plate 10, the second side plate plate 20, and the fire bed plate 30 are firmly supported by each other. Therefore, since the bonfire can be ignited only by the foldable bonfire 1, it is excellent in convenience and storability, and the bonfire can be easily enjoyed.

Further, in the foldable bonfire 1, the fire bed plate 30 at the time of use functions as a fire bed on which fuel materials such as firewood and charcoal are placed, and further, the first side plate plate 10 and the second side plate plate 20 Since the lower part of each of the fire bed plates 30 below the bridged part functions as an ash tray for the bonfire, there is no need to lay a separate ash tray or heat-resistant sheet under the bonfire, which is convenient. It has excellent storability and you can easily enjoy the bonfire.

In the foldable bonfire 1, as described above, when the first side plate plate 10 and the second side plate plate 20 are relatively opened in a substantially V shape with the connecting portion 2 as an axis, the arc of the second side plate plate 20 is formed. The substantially semicircular lower end portion 21 of the second side plate plate is pushed into the flat plate of the first side plate plate 10 and repels the push of the lower end portion 21 of the second side plate plate to repel the push of the lower end portion 21 of the second side plate plate. Both ends, that is, the slits 13 and 13 at both ends and the protrusions 23 and 23 at both ends are pulled together by the rigid force of the substantially flat plate, and extend from the upper end to the lower end of the first side plate 10 and the second side plate 20 respectively. The vicinity of the center bends in a concave shape to form a side plate in the shape of an eaves gutter. Due to this gutter-shaped side plate, the foldable bonfire 1 is made of a relatively thin metal, which is stronger against a load from above than a bonfire composed only of flat plates. Even if it is composed of the above plates, it can sufficiently withstand the load from above.

As described above, in the foldable bonfire 1, the protrusions 22 are formed in a hook shape as the protrusions 23 and 23 at both ends and the central protrusion 24. That is, as described above, in the foldable bonfire 1, the first side plate plate 10 and the second side plate plate 20 are connected by inserting the protrusion 22 into the slit portion 12 at the connecting portion 2. When the first side plate plate 10 and the second side plate plate 20 are relatively opened in a substantially V shape, the force with which the lower end portion 21 of the second side plate plate is pushed into the first side plate plate 10 and the substantially flat plate shape of each other. The first side plate plate 10 and the second side plate plate 20 are configured to bend due to the rigidity of the plates. Therefore, when the first side plate plate 10 and the second side plate plate 20 are opened in a substantially V shape, a load due to the above-mentioned force is likely to be applied to the protrusion 22 and the slit portion 12, and the protrusion 22 is the slit portion 12. There is a risk of falling out of. Therefore, by forming the protrusion 22 as an uncinate process, it is possible to prevent the protrusion 22 from coming off and safely open and close the first side plate 10 and the second side plate 20.

In the foldable bonfire 1, an air discharge hole 36 composed of a round hole 34 and a rectangular hole 35 for circulating air is formed in the fire bed plate 30, and both ends of the shaft in the connecting portion 2 during use are formed.

That is, in the foldable bonfire 1, when fuel materials such as firewood and charcoal are put on the fire bed plate 30, the air required for burning the fuel materials is the air discharge hole 36 and the air supply hole 60. By being supplied through and, the fuel efficiency of the fuel material can be improved. Further, the ash after the fuel material has finished burning is more than the portion where the fire bed plate 30 is bridged in each of the first side plate plate 10 and the second side plate plate 20 which function as ash receivers through the air discharge hole 36. By falling to the bottom, it is possible to prevent the fuel material from being buried in the ash and becoming difficult to burn.

The foldable bonfire 1 is a first for locking a mounting table on which a mounting body, which is a cooking utensil or a cooking utensil, is placed, at the upper end of the first side plate plate 10 and the upper end of the second side plate plate 20, respectively.
