ABSTRACT:
A retractable wheel assembly, housed in an inverted well, has an elongated arm mounting wheels, is pivotally mounted in the well and is pivotally movable manually between a retracted position by which the arm is releasably locked interiorly of the inverted well and an extended operative position by which the arm is releasably locked with its wheels exposed. The arm has spring-biased detents for such manipulatively releasable locking engagements with detent recesses for both positions. Wheel assemblies in bottom rear-corner wells of a suitcase allow "wheel-barrowing" movement of the suitcase. Wheel assemblies in the bottom inverted wells at all four suitcase corners allow "trolleying" movement of the suitcase.
