駆動構造。 A drive structure for an elevating bed that drives an elevating body on the side of the bed main body up and down with respect to a support base, in which a first link and a second link are pivotally connected at an intermediate position by a rotation axis so as to be relatively rotatable. A driving link is pivotally connected and interposed between the support base and the elevating body, and the first link and the second link have a lifting position in which the upper ends and lower ends of the first link and the second link are close to each other, and the first link and the second link A drive means is provided for switching to a lowering position in which the upper and lower ends are separated from each other, and a driven link having the same shape and size as the drive link is arranged in parallel with the drive link in the length direction of the support platform and the elevating body. It is pivotally connected and interposed between the support base and the elevating body, and the rotation shaft portion of the drive link and the rotation shaft of the driven link are connected by a connecting rod, and the movement of the drive link and the movement of the driven link are controlled. A drive structure for an elevating bed that makes the same movement.
