Abstract
A swing-away joystick mounting assembly (20) for mounting a joystick (12) to a wheelchair frame member (11). The joystick mounting assembly (20) produces pantographic movement of the joystick device (12) between a retracted position and an extended position to adjust the placement of the joystick (12). Ingress and egress to and from the wheelchair are eased while, further, permitting the wheelchair to be moved closer to a table or desktop (14). A pair of arms (24, 24') are pivotally mounted at first ends (25, 25') to a first mounting mechanism (21) at spaced apart locations and pivotally mounted at second ends (26, 26') to a second mounting mechanism (22) at spaced apart locations. This four-bar configuration produces pantographic movement of the second mounting mechanism with the joystick device (12) carried thereby between the retracted position and the extended position. A latch mechanism (27) releasably secures the arms (24, 24') together in either the retracted position or the extended position. A spring biasing mechanism (30 ) biases the arms (24, 24') toward an intermediate position from both the retracted position and the extended position. This permits one-handed operation…
