SOLUTION: This system is provided with the bed plate for which a back plate member 11, 1st hinge part 21, hip plate member 12, 2nd hinge part 22, thigh plate member 13, 3rd hinge part 23 and leg plate member 14 are successively linked in this order, and a base 30 arranged under the bed plate is equipped with a driving member 35, 1st and 2nd operating shafts 40 and 50 and 1st and 2nd operating members 60 and 70. While turning (b) the 1st operating shaft 40 at a prescribed angle through the elongating action of this driving member 35, the back plate member 11 is turned like an arrow c1 through a turn (c) of the 1st operating member 60 and the hip plate member 12 is raised up to the upside of a bed. Further, a pull arm 71 of the 2nd operating member 70 is moved back and forth (e), the thigh plate member 13 is turned like an arrow e1, and the leg plate member 14 is pulled to the side of head of the bed.</p> |
