PROBLEM TO BE SOLVED: To provide a motor-driven bed capable of lowering a floor.SOLUTION: The motor-driven bed includes: an upper frame part 2 for mounting a bed floor plate 3 a leg part 4 for supporting the upper frame part 2 above an installation surface A an auxiliary leg part 5 set to the upper frame part 2 and the leg part 4 and an actuator 6 for the upper frame part to be flexibly driven for the vertical movement of the upper frame part 2. A slide part 7 slid in parallel along the upper frame part 2 is provided at the upper end of the leg part 4. The motor-driven bed 1 is constituted so as to freely rotatably pivot at the upper frame part 2 at one end of the auxiliary leg part 5 and freely rotatably pivot at the leg part 4 at the other end. The proximal end of the actuator 6 for the upper frame part is attached to the side of the upper frame part 2 and the end is freely rotatably pivoted at the slide part 7.COPYRIGHT: (C)2008,JPO&INPIT【課題】 低床化を図ることのできる電動ベッドを提供する。【解決手段】 ベッド床板3を載設する上枠部2と、上枠部2を設置面Aの上方位置に支持するための脚部4と、上枠部2と脚部4とに渡される補助脚部5と、上枠部2の上下移動のために伸縮駆動される上枠部用アクチュエータ6とを備える。脚部4の上端に上枠部2に沿わせて平行に摺動させる摺動部7を設ける。補助脚部5の一端を上枠部2に回転自在に枢支すると共に他端を脚部4に回転自在に枢支して成る電動ベッド1である。上枠部用アクチュエータ6の基端を上枠部2側に取り付けると共に、先端を上記摺動部7に回転自在に枢支する。【選択図】図1
