Claims (3)
- ロープで連結されたかごとカウンターウェイトが昇降するエレベータの昇降路に設けられ、昇降路ピット上のカウンターウェイト昇降エリアに作業者が入り込むのを防止するエレベータの作業保護装置において、
保護板をカウンターウェイト昇降エリアとかご昇降エリアに近接・離反する方向に移動可能に設置し、その保護板を、カウンターウェイトとかごに対する干渉を回避するように両者の昇降作動に応じて移動させることを特徴とするエレベータの作業保護装置。 - カウンターウェイトとかごの昇降作動に連動して前記保護板を進退移動させる連動機構を設けたことを特徴とする請求項1に記載のエレベータの作業保護装置。
- 前記連動機構は、前記保護板をカウンターウェイト昇降エリア方向に付勢する付勢手段と、カウンターウェイトが昇降路ピット近くまで下降したときに、カウンターウェイトの下降作動を前記保護板のかご昇降エリア方向の前進作動に変換するカム機構と、を備えていることを特徴とする請求項2に記載のエレベータの作業保護装置。
