Abstract
Abstract An improved movable support bar which is mounted by an upstanding support tube to aid disabled or invalid persons. The movable support bar includes a pivotal support arm mounted into the support tube which is securely retained in the support tube and can be adjusted in height relative to the support tube. The pivotal support arm can be rotated freely between positions by lifting the pivotal support arm or can include a trigger release. The pivotal support arm is retained in the support tube by a bushing mounted in the support tube and retaining pins extending through the pivotal support arm above and below the bushing. The upper pin is secured in slots in the bushing surface to fix the positions of the pivotal support arm. The support tube can be mounted onto a floor surface by a base support member or onto a bed frame by a flange.
