Abstract: A support comprises a first support member formed for mounting to a wheelchair frame. A second support member is formed to carry a joystick. A pair of bars has first ends and second ends. The first ends are pivotally mounted to the first support member at spaced apart locations. The second ends are pivotally mounted to the second support member at spaced apart locations to form a four-bar pantographic linkage assembly. The four-bar pantographic linkage assembly produces pantographic movement of the second support member with the joystick carried by the second support member between an extended position and a retracted position. A latch mechanism is provided between the pair of bars for releasably securing bars together in either the extended position or the retracted position. The latch mechanism includes a magnet exposed along an inner facing side wall of at least one bar. A steel insert is exposed along an inner facing side wall of the other one of the bars.
