Abstract
簡単な構成でありながら、従来よりも一層制振効果を顕著にすることができる衝撃吸収装置1を提供することである。
【解決手段】
制振対象物3に接触させた質量要素11を備え、前記制振対象物3に外力が加わると、その質量要素11が前記外力によるエネルギを吸収して前記制振対象物3から離間運動するように構成した衝撃吸収装置1であって、
前記制振対象物3に前記外力が加わる際に、前記制振対象物3に前記外力と逆向きの方向に力を与える加圧手段を備えていることを特徴とする
【選択図】図1

- 制振対象物に接触させた質量要素を備え、前記制振対象物に外力が加わると、その質量要素が前記外力によるエネルギを吸収して前記制振対象物から離間運動するように構成した衝撃吸収装置であって、
前記制振対象物に前記外力が加わる際に、前記制振対象物に前記外力と逆向きの方向に力を与える加圧手段を備えていることを特徴とする衝撃吸収装置。 - 前記加圧手段が、
前記質量要素に接続された弾性体と、
前記弾性体を弾性変形させた状態で保持する保持機構と、を備え、
前記制振対象物に前記外力が加わる際に、前記保持機構が前記質量要素を開放して、前記弾性体の弾性復帰力を前記制振対象物に前記外力と逆向きの方向に与えることを特徴とする請求項1記載の衝撃吸収措置。 - 前記外力が、衝撃力であることを特徴とする請求項1又は2記載の衝撃吸収装置。
- 前記質量要素が、前記制振対象物が外力を受けて動く方向と略同一な方向に進退するものであることを特徴とする請求項1、2又は3記載の衝撃吸収装置。
- 前記外力を前記制振対象物に加える作用体が制振対象物から所定距離離れた位置にあること検出する検出機構をさらに備え、
当該検出機構が、前記作用体が所定位置にあることを検出してから、所定時間経過後に、前記保持機構が前記質量要素を開放するものであることを特徴とする請求項1、2、3又は4記載の衝撃吸収装置。 - 前記質量要素を前記制振対象物に点又は面接触させていることを特徴とする請求項1、2、3、4又は5記載の衝撃吸収装置。
- 前記質量要素が前記制振対象物から離間運動した後に、再び前記質量要素を前記制振対象物に接触させる復元機構をさらに備えていることを特徴とする請求項1、2、3、4、5又は6記載の衝撃吸収装置。
- 前記復元機構が、弾性体と、減衰器とからなることを特徴とする請求項7記載の衝撃吸収装置。
