Description

【0001】
【発明の属する技術分野】
この発明は、液化ブタン等が充填されたカセットボンベを燃料とする携帯用コンロに関するものである。またこの発明は、コンパクトに折畳むことができる携帯に便利な携帯用ガスコンロに関するものである。
【0002】
【従来の技術とその課題】
従来、ガスを燃料とする携帯用のガスコンロは、種々あっても未だポケットに簡単に収容するほどコンパクトなものはない。
【0003】
その理由の一つは、コンパクトにすると、使用中に下方のテーブルなどへの遮熱を行いにくいという問題である。
【0004】
また、液化ブタン等が充填されたカセットボンベを燃料とするバーナーやコンロなどの器具の端部には、カセットボンベを装着するために、装着キャップが設置されているが、バーナーやコンロなどの器具に設けられる装着キャップは、カセットボンベの頭部の凹部端面に設けられたリングに被せられるため、装着キャップの大きさが、カセットボンベ頭部のリングよりも大きくなる。このため、装着キャップの径よりも厚みの薄いコンパクトな携帯用コンロは、製作できないとされていた。
【0005】
そこで、この発明は、従来の携帯用のガスコンロよりも格段に薄くて、ポケットに容易に収容することができ、しかも、使用する際には、下方への熱を遮断して、テーブルなどを焦がさない安全性に優れた携帯用ガスコンロを得ようとするものである。
【0006】
【課題を解決するための手段】
この発明に係る携帯用ガスコンロは、ヒンジによってV字形に開く左右一対の箱体からなる矩形の金属製の収容ケースと、この収容ケースに対して着脱可能で、収容ケース内に収容されるコンロ本体と、上記左右の箱体をV字形に開いた状態で立てる脚部とを備え、
コンロの不使用時に、上記収容ケース内に上記コンロ本体を収容して、上記左右一対の箱体を閉じる一方で、コンロの使用時に、V字形に開かれた上記左右の箱体の上辺を、鍋等を載置する五徳部として用いるようにしている。
【0007】
V字形に開いた左右の箱体にコンロ本体を取り付けると、左右の箱体が遮熱板になると共に、上方に熱を反射するので、熱効率がよい。また、開いたV字形の箱体の上辺にそのまま鍋等を載置することができるので、五徳などを別途用意する必要がなく、携帯用ガスコンロの大きさをコンパクトにできる。
【0008】
また、V字形に開いた左右の箱体は、風防として作用する。
【0009】
さらに、上記コンロ本体の端部に設置するカセットボンベ装着装置を、次のような構造にすることにより、より厚さの薄い携帯用ガスコンロを得ることができる。
【0010】
即ち、カセットボンベ装着装置は、カセットボンベの頭部の開栓バルブに被せる開栓筒と、カセットボンベの頭部の装着用リングの外面で、一直線状に揃った状態から十字形に開くように、互いに中央部分で回動可能に組み合わされている扁平形状の一対のアーム部材とからなる。上記一方のアーム部材には、その中央部に、開栓筒と同形状の底部と、この底部から起立する一対の固定壁とからなる開栓筒保持部を設けている。この開栓筒保持部の固定壁の先端外面には、カセットボンベの頭部凹部の内周面に形成された段部に引っ掛かる割り爪部を形成している。上記他方のアーム部材の中央部には、上記開栓筒保持部が回転可能に嵌まる凹所を設けている。上記一対のアーム部材の中央部分には、コンロ本体の燃焼部に接続される接続筒を貫通させる貫通孔を形成し、この貫通孔を通して接続筒と開栓筒とを接続している。上記コンロ本体の接続筒の先端には、左右に突き出すロック部が形成され、このロック部の通過孔を、上記一対のアーム部材の中央部分に形成した貫通孔に連続して形成している。
【0011】
上記一対のアーム部材を一直線状に揃え、開栓筒を開栓筒保持部の底側に位置させた状態で、カセットボンベの頭部凹部の内周面に形成された段部に、アーム部材の開栓筒保持部の割り爪部を嵌め入れる。この後、コンロ本体とカセットボンベとを押し付けて、開栓筒を開栓筒保持部の割り爪部側に位置させて、接続筒のロック部を、一対のアーム部材の中央部分に形成した通過孔を通過させた状態で、一対のアーム部材を十字形に開くと、ロック部がアーム部材に形成した開栓筒保持部の底部の内側に位置し、開栓筒が開栓筒保持部の割り爪部側に位置させた状態に保持され、 一対のアーム部材とカセットボンベとが固定される。
【0012】
上記のカセットボンベ装着装置は、装着前の状態では、一対の装着用のアーム部材を一直線状に揃えておくことができるので、より厚さの薄い携帯用ガスコンロが得られる
