Claims (2)
- 可燃性ガスと空気とを攪拌混合して得た混合ガスを爆発的に燃焼させる燃焼室と、この高圧の燃焼ガスを打撃シリンダ内に収容された打撃ピストンに作用させて打撃ピストンを打撃シリンダ内で衝撃的に駆動させ、この打撃ピストンの下面側に結合されているドライバを摺動案内して釘を打ち出すノーズ部と、
ノーズ部の下方に配置されてマガジンに収容された連結釘に係脱する送り爪を上記ノーズ部側に送る送りピストン・シリンダ機構とを備え、上記送りピストン・シリンダ機構は上記燃焼室で発生した高圧の燃焼ガスによって上記打撃ピストンの打撃と同時に送りピストンが上記送り爪による送りを解除する方向に作動するガス燃焼式打込み工具において、
上記送り爪によって上記ノーズ部に向かって送られる連結釘に係合し、該送り爪による送りが解除されても先頭の釘が上記ノーズ部内で安定するように上記連結釘を保持する保持機構を備え、
上記保持機構は、連結釘の先頭の釘が射出口内に位置するときに次段の釘に係合するように付勢される逆止爪と、連結釘を連結するワイヤを連結釘の通路の内壁に押し付けて保持するように付勢されるラチェットと、で構成され、上記送り爪による連結釘の送りが解除されても上記逆止爪と上記ラチェットとで連結釘が動かないように保持することを特徴とするガス燃焼式打込み工具。 - 前記保持機構に代えて、前記ドライバがノーズ部内の釘を打撃開始するまで、送り爪の退避を遅延させる遅延構造を前記送りピストン・シリンダ機構に設け、
上記遅延構造は、送りピストンの先端に軸方向に形成した長穴で構成され、この長穴に送り爪の係合軸を係合させて送り爪を送りピストンに連結し、送りピストンが長穴の長さ分だけ移動しないと送り爪が動き始めないように形成したことを特徴とする、請求項1記載のガス燃焼式打込み工具。
