- 銃本体に前進後退可能に設けられ、弾丸発射によって発生したガスの圧力により後退してボルトスプリングを蓄圧し、蓄圧された圧力の解放により前進して弾丸装填の動作を行なうボルト部材と、ボルト部材の前進を停止させるボルトストップを備えた銃において、
ボルトストップは、最終弾丸発射後に前進して来るボルト部材と係合する係合手段を有し、上記係合によってボルトストップに加えられる衝撃力を緩衝するために、ボルトストップに作用する緩衝手段を具備し、
前記ボルトストップは、銃本体側に設けられた軸が配置される前後方向の長孔を有しており、上記長孔の範囲で移動可能、かつ、軸を中心として回転可能に設けられている銃におけるボルトストップ緩衝装置。 - 銃本体に前進後退可能に設けられ、弾丸発射によって発生したガスの圧力により後退してボルトスプリングを蓄圧し、蓄圧された圧力の解放により前進して弾丸装填の動作を行なうボルト部材と、ボルト部材の前進を停止させるボルトストップを備えた銃において、
ボルトストップは、最終弾丸発射後に前進して来るボルト部材と係合する係合手段を有し、上記係合によってボルトストップに加えられる衝撃力を緩衝するために、ボルトストップに作用する緩衝手段を具備し、
前記係合手段は、ボルト部材に設けられた係合部とボルトストップに設けられた係合相手部とから成り、ボルト部材の前進方向に対して鋭角を構成するように設けられている銃におけるボルトストップ緩衝装置。 - 銃本体は、銃の操作に伴って装弾部に供給される弾丸の有無を検出する弾切れ検出手段を有し、上記弾切れ検出手段は、弾切れを検出するとともに、ボルト部材が前進後退する際の軌道内にボルトストップを突出させ、係合手段による係合を可能にする連絡のためのリンク機構を具備している請求項1または2記載の銃におけるボルトストップ緩衝装置。
- ボルトストップは、前進して来るボルト部材の衝撃を受け止めるとともに、緩衝手段に伝達するボルトストップ機構をボルト部材と緩衝手段の間に具備しており、緩衝手段は、上記衝撃の伝達によって弾性変形する弾性部材を備えている請求項1または2記載の銃におけるボルトストップ緩衝装置。
