Abstract
A suitcase surrounded by paired circular raceways forming an endless track is disclosed. Into each of these raceways there is mounted a complementary revolving rim rotating upon bearings placed at intervals around the raceway. The rim, preferably taking the form of a circular tube, surrounds the suitcase. This rim forms the points of rotating transport over the ground. In operation, the suitcase is propelled by a handle which protrudes from the end wall of the suitcase between the raceways, yet permits convenient opening of the suitcase. The suitcase, because of its attachment at the handle, does not rotate. The tubes within the raceways do rotate and provide continuously revolving contact points with the ground.
