<p>PURPOSE:To make it possible to perform easily conversion of body position by dividing a floor plate of a bed into three parts in the width direction, connecting them freely bending each other, supporting freely rotatively floor parts of end sides on freely movable supporting link supported freely rotatively on a floor-supporting body and placing an elevation driving mechanism between the floor plate and the floor supporting body. CONSTITUTION:A floor plate 1 of a bed is divided into three parts in the width direction and they are connected freely bending each other. A central floor part 1b is supported with free vibration on a floor supporting body 3 at the central part as a fulcrum 2 and floor parts 1a and 1c of the end parts are supported with free rotation on freely movable supporting links 4a and 4b supported with free rotation on the floor supporting body 3. In addition, an air pressure-movable bellows type elevation driving mechanism 5 is placed between the floor plate 1 and the floor supporting body 3 to constitute a floor supporting mechanism of the bed. To perform conversion of body position of a patient 10 on the floor plate 1, the central floor part 1b is at first gradually inclined so as to make the left side lower, e.g. to 45 deg.-60 deg. and then, an attendant on the sick can easily let the patient 10 turn over furthermore to the inclined direction.</p> |
