Abstract
Abstract A cushion unit with an opening section is placed atop a bed frame. Rails are laid under the bed frame, and a truck reciprocated by a drive mechanism is placed on the rails for traveling. The truck carries movable units on which an elastic pad and a urinal are mounted. Each of the units is provided with guide rollers for vertical movement within guide members extending under the bed frame, facing the opening section. The guide rollers associated with the elastic pad or the urinal engage with the guide members according to the direction of travel of the truck, thus raising either the elastic pad or the urinal from the truck to fit the same into the opening section of the bed cushion unit.
