Abstract
A case having at least one wheel mounted adjacent the case's floor, that wheel being retractable interiorly of the case into a storage position and extendable exteriorly of the case below the floor where the case can roll on the wheel. One feature is that a retract operator connected to the wheel is manually movable in one of generally parallel and normal directions relative to the floor in order to retract the wheel into the storage position, and a separate extend operator also connected to the wheel is manually movable in the other of the generally parallel and normally directions relative to the floor in order to extend the wheel into the use position. Another feature is that a single spring motor is connected with both the retract and extend operator in order to continually bias both those operators toward one of each operator's first and second operational positions. A third feature includes a pivotable drum to which the wheel is connected by a crank arm, the drum moving the wheel between storage and use positions in response to the operators and a drum spring motor, and a latch cooperable with the drum to hold it in that position to which the drum is not continually spring biased, that latch being continuously being biased toward the latching position by that same spring motor.
