Abstract
Abstract The apparatus is useful to turn an invalid patient ninety degrees from one resting position to a second resting position by standing the patient on a foot plate. A base platform supports the foot plate with a turntable mounted between the foot plate and base platform. A central bore in the foot plate, turntable and base platform permits a bolt to hold the foot plate, turntable and base platform together. An eccentric bore in the foot plate receives a long shafted bolt attached to the foot plate with a portion of the shaft descending below the foot plate to move within a groove in the base plate to permit about a ninety degree rotation of the foot plate.
