Abstract: An automatic care-taking system for a bed-ridden patient comprising a bed body having three rectangular, horizontally disposed bed plates arrayed on a bed frame in planar relationship to each other, the three bed plates being pivotally connected to each other, the first bed plate to the second bed plate and the second bed plate to the third bed plate. The pivotally connected bed plates are adapted to be driven by bars and rockable rods. When the rod connecting the first and second bed plates is driven, the first and second bed plates tilt to form a V-shape while the third bed plate remains horizontal. When the bar connecting the second and third bed plates is driven, the second and third bed plates tilt to form a V-shape while the first bed plate remains in a horizontal position.
