Claims (3)
- ハウジングと、
該ハウジングの一端に設けられ、可燃性ガス通路が形成されたヘッド部と、
該ハウジングの他端側に設けられ、工作物への押圧時に移動可能なプッシュレバーと、
該ハウジング内に固定して設けられたシリンダと、
該シリンダの軸方向に該シリンダに対して往復摺動可能なピストンと、
該プッシュレバーに連接され、該ハウジング内において該シリンダに移動可能に案内され、該ヘッド部に当接、離間し、該ヘッド部、該シリンダ、該ピストンと共に燃焼室を画成する燃焼室枠と、
該ピストンから反燃焼室方向に延びるドライバブレードと、
該燃焼室内の可燃性ガスと空気との混合気に着火するために該燃焼室に臨む点火プラグと、
該燃焼室内に配置されて可燃性ガスと空気とを攪拌混合するファンとを有し、
該燃焼室枠は、該プッシュレバーに連接される枠基体と、該枠基体の反プッシュレバー側に位置して該ヘッド部に当接可能な枠頭部とを有し、
該枠頭部は、外端が該枠基部に接続され該ファンの回転軸に向って延びる接続部と、該接続部の内端から該ファンの回転軸方向に沿って延び該ヘッド部に当接、離間する当接ガイド部とを有し、
該可燃性ガスが該可燃性ガス通路を介して該燃焼室に供給され、該点火プラグの点火動作により該混合気が爆発燃焼して該ピストン及び該ドライバブレードを移動させる燃焼式動力工具において、
非作動の状態における該回転軸方向の該ファンの中央部が、該接続部よりも該ピストン側に位置するように、該ファンが配置されていることを特徴とする燃焼式動力工具。 - 非作動の状態における該回転軸方向の該ファンの該ヘッド部側の端部が、該接続部と一致するか又は該接続部よりも該ヘッド部側に位置するように、該ファンが配置されていることを特徴とする請求項1に記載の燃焼式動力工具。
- 該ハウジング内には、該プッシュレバーが工作物に押しつけられて該プッシュレバーが該ハウジング内に後退し該燃焼室枠が所定位置に達したことを検出するヘッドスイッチが設けられ、
該ヘッド部には、該ファンを回転させるためのモータが設けられ、
該モータは、該ヘッドスイッチの検出開始によって電力が供給され、該ファンを回転させるとともに、該混合気の爆発燃焼後に、該プッシュレバーを該ハウジングから突出動作させ該燃焼室枠が該所定位置から移動して、該ヘッドスイッチが検出を終了してから7秒以内に電力供給が停止されることを特徴とする請求項2に記載の燃焼式動力工具。
