Abstract
A work-engaging member is attached to the wheelchair frame adjacent to the footrest assembly of a wheelchair to cause latching and releasing of the footrest assembly for rotation about a vertical axis. As the work-engaging member is turned by a rotatable means a surface thereon which is spaced from the axis of rotation slidably contacts the footrest assembly to push the footrest assembly latch and causes the footrest assembly to swing to the side of the wheelchair. Rotation of the work-engaging member in the opposite direction causes the device to contact a surface of the footrest assembly thereby laterally urging the footrest assembly around the vertical axis so as to reposition and cause the latching of the footrest assembly into a locked position in front of the wheelchair.
