Abstract
A locking apparatus is operative to selectively prevent the folding of a wheelchair of the type having a pair of centrally pivoted cross braces under the wheelchair seat. A bracket member is provided at each end of a pin which is adapted to constitute the pivot for the cross braces. An elongate bar is hinged at one end to one of the brackets and is adapted to be swung into a position between the cross braces so as to obstruct folding. A locking device operates between the other end of the bar and the other of the brackets for selectively retaining the bar in obstructing position.
