LIFT FOR WHEELCHAIR

PROBLEM TO BE SOLVED: To provide a lift for a wheelchair with higher safety by having a blockage bar for preventing a user from falling from a table and depending on a state of this blockage bar by restricting a lifting motion of a lift for a wheelchair and a standing state and a lodging state of a slope or a bridge.SOLUTION: A lifting part is arranged on both right and left sides of a table of a lift for a wheelchair and a safety device constituted of a plurality of linkages is provided for operating simultaneously an operation of an open state and a closed state of a blockage bar bearing pivotably to an end of the blockage bar, and an operation of a standing state and a lodging state of a slope and a bridge bearing pivotably to front and rear both ends of the table. The safety device of a slope side is provided with an opening and closing locking mechanism for restricting an operation of the safety device to operate only at the lowest position by interlocking to a lifting of the table.SELECTED DRAWING: Figure 5 【課題】利用者がテーブルから転落するのを防止するための遮断棒を備えると共に、この遮断棒の状態によっては車椅子用昇降機の昇降動作及びスロープもしくはブリッジの起立状態と倒伏状態を制限することで、より安全性が高い車椅子用昇降機を提供すること。【解決手段】車椅子用昇降機のテーブルの左右両側に昇降部を配設し、この遮断棒の端部に回動自在に支承される遮断棒の開放状態と遮断状態の操作と、テーブルの前後両端縁部に回動自在に軸支されるスロープ及びブリッジの起立状態と倒伏状態の操作を同時に操作できるように複数のリンクで構成される安全装置を具備し、スロープ側の安全装置はテーブルが最低位でしか操作できないようにテーブルの昇降に併せて連動することで安全装置の操作に規制をかけることが可能な開閉ロック機構を具備した。【選択図】図５
