    Abstract: A recreational chair converter is disclosed. The chair converter will convert a folding chair with a U shaped rear support leg from its normal use as a chair to a transport cart. The chair converter is provided with a pair of wheels mounted on an axle and has a pair of elongated segments attached to each other by means of living hinges and bolts. Each segment has two lengthwise grooves so that the pair of segments, when attached together, will form two parallel cylindrical openings which receive and hold the axle equipped with wheels and the rear support leg of a recreational chair. The pair of segments are securely attached to and are completely around the rear tubular leg of a recreational chair. There is also provided a tension strap and buckle which holds the chair securely to said pair of segments and allows the converter device to be used as a transport cart when it is desired.
