Abstract
Abstract An accessory to make suitcases wheeled for manual propulsion. The base of an accessory unit - one near each end of the suitcase - is tied to the same by a strap which is adjustable by a buckle either on top or on the side of the suitcase. The bases receive slides underneath which carry the wheels, with latches to keep the slides in place. When these are unlatched and removed, the straps and bases remain with the suitcase; and the slides and wheels make a small package conveniently carried by the owner of the suitcase.
