PROBLEM TO BE SOLVED: To provide a bed in which a leg part of a sleeping bed has a structure in which a patient repeats a rise/fall in a horizontal position, so that the patient has a posture to be hardly fatigued because the patient does not become an unnatural posture, and becomes an easy posture.SOLUTION: An existing bed immediately fatigues a patient because patients legs in a horizontal position obstructs a natural posture. If making a leg part have a structure to come down in a chair state not but a level, the legs are not the hindrance. An elevated bed is made to have a structure to use a power source for coming down the leg part also as a derricking motor of the back. A part in which a legless chair rises/falls by operation of the derricking motor and a part in which the leg part rises/falls are connected by levers, and a part in which each lever 1 bends is made to have a joint structure 2. Because the bed comes into a chair state and becomes a bed for sleeping, there is no case that the patient becomes an unnatural posture and is fatigued.COPYRIGHT: (C)2015,JPO&INPIT【課題】就寝ベッドの脚部は、患者が水平の位置で起伏を繰り返す構造であり、不自然な姿勢とならず、楽な姿勢で疲労の少ないベッドを提供する。【解決手段】既存のベットは水平な位置の自分の足が邪魔になりすぐに疲れてしまう、脚部を水平ではなく椅子状に下がる構造にすれば、邪魔になることは無くなる。脚部を下げる動力源を背中の起伏用モーターと兼用した構造としたことで、起伏用モーターが作動して座椅子が起伏する個所と脚部が起伏する個所をテコで連結し、各々のテコ1が屈曲する個所は関節構造2とする。ベッドは椅子状になったり、就寝のベッドになったりするので患者が不自然な姿勢で疲労するなどということは全くない。【選択図】図2
