Removable travel case caster system

摘要

A wheeled caster assembly engages a carrying case at the handle thereof, but the assembly is easily removed from the case. The caster assembly has a base on which the case rests. The base is supported by a wheeled caster at one end and a strut at the other end. A keel on the underside of the base is disposed between the caster and the strut. The keel contacts the crossbar of the handle such that the upper side of the base faces against the case. A corner of the case fits with a complementary corner formed by the base and an upright flange at the one end of the base.
