ABSTRACT:
Front and rear downwardly extending arm rest support tubes are received in correspondingly positioned front and rear vertical receiving tubes on the side of a wheelchair. A pin is arranged to project into registered openings in the front telescoping tubes so that an arm rest on the arm rest support tubes can be positioned at a selected height and locked in such adjusted position. A specially designed handle is arranged to retract the pin when urged forwardly, the handle being engaged by the web of a patient's hand between the thumb and forefinger, unlocking of the tubes permitting vertical adjustment. Release of the specially designed handle results in automatic biasing of the pin into registration with aligned openings in the front telescoping tubes.
