Abstract
Abstract When bathing invalided persons, it is desirable that the bath tub be located at a certain level above the base flooring. This may be brought about by lifting an ordinary low tub, or by lifting the person to be treated into a high tub. The person rests in a cradle pivotably mounted at a pillar structure, so it can be swung in and out with respect to the tub.
