Description

本発明は、焚火台に関し、分解・折畳みができる機能を有する焚火台に関する。 The present invention relates to a fire pit, and more particularly, to a fire pit that has the ability to be disassembled and folded.

キャンプ場やバーベキュー場等の屋外では、調理をすると共に、明かりを灯し、且つ暖をとるために焚火が用いられているが、焚火は、基本的に認められた場所以外で行うことが禁止され、さらには、認められた場所においても、地面で直接焚火を行うことが禁止されていることが多い。 Bonfires are used outdoors, such as at campgrounds and barbecue areas, for cooking, lighting, and warmth, but bonfires are generally prohibited outside of authorized locations. Moreover, even in permitted places, it is often prohibited to light a fire directly on the ground.

このため、地面から離れた位置に火床を備え、この火床上で焚火ができる焚火台が開発されている。また、持ち運びに便利なように、分解・折畳みができる機能を有する焚火台も開発されている（特許文献１参照） For this reason, fire pits have been developed that are equipped with a fire bed located away from the ground and on which a fire can be started. Additionally, fire pits have been developed that can be disassembled and folded for convenient portability (see Patent Document 1).

特許文献１に記載の従来の焚火台は、分解・折畳み自在な支持台および支持台に着脱自在に取り付けられる火床を備えている。支持台は２つの部材で構成され、部材夫々が折畳める構造を有し、火床は、柔軟性を有する織布であり折畳み自在である。 The conventional fire stand described in Patent Document 1 includes a support stand that can be disassembled and folded, and a fire bed that is detachably attached to the support stand. The support base is composed of two members, each of which has a foldable structure, and the fire bed is made of flexible woven fabric and is foldable.

火床の四隅には懸架線が設けられており、この懸架線を組立てられた支持台の四隅に引っ掛けることで火床を支持台に設置することができ、懸架線を支持台から外すことによって火床を支持台から取外すことができるようになっている。 Catenary wires are provided at the four corners of the fire bed, and by hooking these wires to the four corners of the assembled support base, the fire bed can be installed on the support base, and by removing the catenary wires from the support base. The grate can be removed from the support.

しかしながら、従来の焚火台は、火床が織布であるため空気の通りが悪く燃料の燃焼効率が低いという問題がある。また、支持台には火床の懸架線を引っ掛けるための掛止凹部が形成されているが、支持台に対する火床の着脱の度に、掛止凹部に対して懸架線を引っ掛けたり取外したりすることが面倒であるという問題がある。さらに、支持台が２つの部材の組み合わせであるため、組立て・分解が面倒であるという問題がある。 However, since the fire bed of the conventional fire pit is made of woven fabric, there is a problem in that the airflow is poor and the fuel combustion efficiency is low. In addition, the support base is formed with a hooking recess for hooking the firebed's suspension line, and each time the firebed is attached to and removed from the support base, the suspension line is hooked to and removed from the hooking recess. The problem is that it is troublesome. Furthermore, since the support base is a combination of two members, there is a problem in that it is troublesome to assemble and disassemble.

そのため、現在では、高い燃焼効率を有すると共に、支持台に対する設置・取外しが簡単な火床を備え、しかも、組立て・折畳みが簡単な支持台を備えた焚火台の開発が望まれている。 Therefore, there is currently a demand for the development of a fire stand that has high combustion efficiency, is equipped with a fire bed that is easy to install and remove from the support stand, and is equipped with a support stand that is easy to assemble and fold.

In the following description, the same reference numerals in different figures indicate parts with the same function, and redundant explanation in each figure will be omitted as appropriate.

[全体の構成]
焚火台Ａは、図１および図２に示すように、火床Ｂと、火床Ｂを着脱自在に載置する支持台Ｃと、支持台Ｃ上において、調理器具等を載置する五徳Ｄとを備えたものである。火床Ｂは、屈曲変形自在な弾性を有したネットが用いられており、支持台Ｃに対して着脱自在に載置されている。支持台Ｃは、折畳み自在であり、収納（運搬）時には図７に示すように折畳み、使用時には図１に示すように拡開することができるようにされている。 [Overall configuration]
As shown in FIGS. 1 and 2, the bonfire stand A includes a fire bed B, a support stand C on which the fire bed B is removably placed, and a trivet D on which cooking utensils and the like are placed on the support stand C. It is equipped with the following. The fire bed B is made of an elastic net that can be bent and deformed, and is placed on the support base C so as to be detachable. The support stand C is foldable, and can be folded up as shown in FIG. 7 when stored (transported), and expanded as shown in FIG. 1 when used.

[火床の構成]
火床Ｂは、図１および図２に示すように、耐熱性および可撓性を有するメッシュ材を用いて、平面長方形のメッシュシートとして形成されており、火床Ｂの使用時においては、図１に示すように断面半円状に湾曲させて支持台Ｃに載置することで燃料（木炭や薪等）の置き場を確保し、火床Ｂを取外したときには、図２に示すように平坦状にすることができると共に、筒状に丸めて収容状態（図示せず）とすることができるようにされている。 [Fire bed configuration]
As shown in FIGS. 1 and 2, the fire bed B is formed as a mesh sheet with a rectangular plane using a heat-resistant and flexible mesh material. As shown in Figure 1, by placing the fuel (charcoal, firewood, etc.) on a support stand C with a curved cross section, a place for storing fuel (charcoal, firewood, etc.) can be secured, and when the fire bed B is removed, it will be flat as shown in Figure 2. It can be made into a shape, and can also be rolled into a cylindrical shape to be in a stored state (not shown).
