  • Patent number: 4852705
    Abstract: The case has a self-contained handle and wheels which can be extended for rolling the case along or retracted for stowing the case. The wheels are mounted to framework inside of the case by a mounting rod, which rod turns to move the wheels between the stowed and the deployed positions. The handle is also coupled to the framework and can be extended from a stowed position inside of the case to a deployed position outside of the case. The handle is coupled to the wheel mounting rod through a linkage rod which turns the mounting rod. As the handle is extended to the deployed position, the linkage rod turns the mounting rod to deploy the wheels. The wheels are stowed into the case by stowing the handle.
