Zusammenfassung:PROBLEM TO BE SOLVED: To provide an electric bed device having a safety mechanism for preventing a user from being injured by getting caught in an actuation process of an electric bed.SOLUTION: An electric bed device includes: a base 1; a bed board 2 positioned above the base; lifters 3 to which the base and the bed board are connected and that controls lifting/lowering of the bed board; sensor structures 4 arranged under the circumference of the bed board so as to detect a foreign matter; multiple mandrels 5 for connecting the sensor structures to the bed board; multiple projections 7 arranged in the bed board so as to limit an actuation direction of the multiple mandrels; and multiple limit switches 6 arranged in the bed board and positioned close to the multiple mandrels, so as to control behaviors of the lifters. When a foreign matter collides with the sensor structure in lowing the bed board, the sensor structure is displaced toward the bed board and also the multiple mandrels are moved toward the bed board. Then, the multiple limit switches are turned off, so as to stop the behaviors of the lifters.SELECTED DRAWING: Figure 2 【課題】電動ベッドの作動過程において挟まれることによりけがをすることを防ぐ安全機構を有する電動ベッド裝置を提供する。【解決手段】ベース1と、ベースの上方に位置するベッド板2と、ベースとベッド板とが接続され、ベッド板の昇降を制御することができるリフター3と、ベッド板の周囲の下に設けられ、異物を検出するセンサー構造4と、センサー構造とベッド板とを接続する複数のマンドレル5と、ベッド板に設けられ、複数のマンドレルの作動方向を制限する複数の凸部7と、ベッド板に設けられ、且つ複数のマンドレルの近くに位置し、該リフターの動作を制御する複数のリミットスイッチ6とを含み、該ベッド板が下降する際に、異物がセンサー構造に衝突して、センサー構造をベッド板に向かって変位させ、且つ複数のマンドレルをベッド板の方向へ移動させ、複数のリミットスイッチをオフさせ、リフターの動作を停止させる。【選択図】図2
