好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。 Embodiments of the present invention which are considered to be suitable will be briefly described by showing the operation of the present invention based on the drawings.

本発明の焚火台Ａは、支持脚３を地面に接地させると、この支持脚３に支持されている火床２が地面から浮上状態に配設されることとなり、この火床２の燃料収容部10に薪１Ａなどの燃料１を収容して燃焼させることで焚火を行うことが可能である。 In the bonfire A of the present invention, when the support leg 3 is brought into contact with the ground, the fire bed 2 supported by the support leg 3 is arranged in a floating state from the ground, and the fuel storage of the fire bed 2 is provided. It is possible to bonfire by accommodating fuel 1 such as firewood 1A in part 10 and burning it.

また、この際、支持脚３に設けられている支承部13に、焼き網12Ａや五徳などの加熱調理用器具12を支承してこの加熱調理用器具12を支持脚３に支持した火床２の上方に配設すると、焚火で暖を取りつつ加熱調理用器具12を用いて加熱調理を行うこともできる。 At this time, the fire bed 2 which supports the cooking utensil 12 such as the grill 12A and the trivet to the support portion 13 provided on the support leg 3 and supports the cooking utensil 12 on the support leg 3. If it is arranged above the above, it is possible to cook by using the cooking utensil 12 while keeping warm with a bonfire.

また、本発明の火床２は、本体枠４に前板５と後板６と左板７と右板８とが夫々回動自在に枢着され、この前板５と後板６の回動先端部同志が、前記本体枠４より下方位置で連結されることで燃料１を収容可能な凹所９が形成されていると共に、この凹所９上に前記左板７と前記右板８の回動先端部が載置されることにより凹所９の左右両端が塞がれて燃料収容部10が形成されており、更に、前記前板５の回動先端部は、前記後板６に設けられているスライドガイド部11にスライド移動自在に連結されている。 Further, in the fire bed 2 of the present invention, the front plate 5, the rear plate 6, the left plate 7, and the right plate 8 are pivotally attached to the main body frame 4 so as to be rotatable, and the front plate 5 and the rear plate 6 are rotated. A recess 9 capable of accommodating the fuel 1 is formed by connecting the moving tip portions below the main body frame 4, and the left plate 7 and the right plate 8 are formed on the recess 9. The left and right ends of the recess 9 are closed by placing the rotating tip portion of the front plate 9, and the fuel accommodating portion 10 is formed. Further, the rotating tip portion of the front plate 5 is formed by the rear plate 6. It is connected to the slide guide portion 11 provided in the above so that it can be slidably moved.

そのため、不使用時には、支持脚３から取外した火床２を、前記左板７と前記右板８とを上方へ起動回動させてから前板５の先端部を後板６に対しスライド移動させて前板５と後板６を上方へ起動回動させると、この前板５と後板６とが前記本体枠４に沿った偏平状態に重ねられることになり、この偏平に重ねられた前板５と後板６上に更に左板７と右板８を重ねることによって偏平折畳み状態にできる。 Therefore, when not in use, the fire bed 2 removed from the support leg 3 is started and rotated upward with the left plate 7 and the right plate 8, and then the tip portion of the front plate 5 is slid with respect to the rear plate 6. When the front plate 5 and the rear plate 6 are started and rotated upward, the front plate 5 and the rear plate 6 are overlapped in a flat state along the main body frame 4, and the front plate 5 and the rear plate 6 are overlapped in the flat state. By further stacking the left plate 7 and the right plate 8 on the front plate 5 and the rear plate 6, a flat foldable state can be obtained.

即ち、本発明の火床２は、四枚の板材（前板５と後板６と左板７と右板８）が全て偏平に重ねられた非常にコンパクトな折畳み状態にできるので、上記特許文献１よりも収納スペースを取らず、携帯性にも優れる。 That is, the fire bed 2 of the present invention can be in a very compact folded state in which all four plate materials (front plate 5, rear plate 6, left plate 7, and right plate 8) are stacked flat. It takes up less storage space than Document 1 and is also excellent in portability.

一方、前板５の回動先端部となる下側端部には、この回動先端部がカール形状に折曲加工されることによりこの円筒状下端内に連結部材20としての連結軸20が装着されていると共に、この連結軸20の両端部が円筒状下端から左右外側に突出するようにして設けられている。 On the other hand, at the lower end portion which is the rotation tip portion of the front plate 5, the connecting shaft 20 as a connecting member 20 is formed in the cylindrical lower end portion by bending the rotating tip portion into a curl shape. Along with being mounted, both ends of the connecting shaft 20 are provided so as to project outward from the lower end of the cylinder to the left and right.

そして、この連結軸20の両端部が、左右のガイド長孔11に貫通された上でガイド長孔11より径大な円板状に形成されていることにより、連結軸20の両端部が左右のガイド長孔11から抜止状態となり且つガイド長孔11に沿って後板６の上面（前板５との対向内側面）上をスライド移動自在となるように構成されている。 Then, both ends of the connecting shaft 20 are formed in a disk shape having a diameter larger than that of the guide elongated holes 11 after being penetrated through the left and right guide elongated holes 11, so that both ends of the connecting shaft 20 are left and right. It is configured so that it can be pulled out from the guide elongated hole 11 and can be slidably moved along the guide elongated hole 11 on the upper surface of the rear plate 6 (the inner surface facing the front plate 5).

即ち、前記左板７と前記右板８とを邪魔にならないように上方へ起動回動退避させておいてから前板５を上方へ起動回動させると、この前板５の先端部が後板６上をその前記円筒状端部22の方向へスライド移動（連結軸20がガイド長孔11に沿って後板６の円筒状端部22の方向へスライド移動）することとなり、これに伴い後板６も上方へ起動回動していき（図４（ｂ），図５（ｂ）参照）、やがて後板６上に前板５が重ねられてこの前板５と後板６とが前記本体枠４に沿った偏平状態となり、続いてこの偏平に重ねられた前板５と後板６上に、退避させていた左板７と右板８とを重ねることにより、本実施例の火床２は略本体枠４大の偏平折畳み状態とし得るように構成されている（図４（ｃ），図５（ｃ）参照）。 That is, when the left plate 7 and the right plate 8 are started and rotated and retracted upward so as not to be in the way, and then the front plate 5 is started and rotated upward, the tip portion of the front plate 5 is rearward. The connecting shaft 20 slides on the plate 6 in the direction of the cylindrical end 22 (the connecting shaft 20 slides in the direction of the cylindrical end 22 of the rear plate 6 along the guide slot 11). The rear plate 6 also starts and rotates upward (see FIGS. 4 (b) and 5 (b)), and eventually the front plate 5 is superposed on the rear plate 6 and the front plate 5 and the rear plate 6 are connected to each other. A flat state is formed along the main body frame 4, and subsequently, the left plate 7 and the right plate 8 that have been retracted are superposed on the front plate 5 and the rear plate 6 that are superposed on the flat surface. The fire bed 2 is configured so as to be in a flatly folded state having substantially four large main body frames (see FIGS. 4 (c) and 5 (c)).

また、前記凹所９を構成するこの後板６上の左右の前記スライドガイド部11より内側に、前記左板７と前記右板８の回動先端部が載置されて前記燃料収容部10が形成されるように構成されており、これにより燃料収容部10で燃焼した燃料１の灰や燃えカスがスライドガイド部11に至って前板５と後板６のスライド移動を阻害することがない（火床２の折畳みに支障が出ない）ように構成されている。 Further, the rotating tip portions of the left plate 7 and the right plate 8 are placed inside the left and right slide guide portions 11 on the rear plate 6 constituting the recess 9, and the fuel accommodating portion 10 is provided. Is formed so that the ash and burning debris of the fuel 1 burned in the fuel accommodating portion 10 do not reach the slide guide portion 11 and hinder the slide movement of the front plate 5 and the rear plate 6. It is configured so that (the folding of the fire bed 2 is not hindered).
