  • Patent number: 11089852
    Abstract: A retractable wheel mechanism of a suitcase has a main housing, a retractable handle mounted in the main housing, two slidable panels mounted separately in the main housing, and two wheel sets separately mounted in the main housing. By extending or shortening the retractable handle, the slidable panels are driven to slide transversely and drive the wheel sets to protrude out of the main housing or to be retracted in the main housing. An owner of the suitcase can retract the wheel sets whenever he has to carry the suitcase without dirty his clothes, or whenever he has to pull the suitcase into an office or a room without revealing the dirty wheel. Moreover, an appearance of the suitcase becomes compact when the wheel sets are retracted.

  • Publication number: 20190000198
    Abstract: A luggage includes a case and a handle. The handle is connected to the case through two telescopic rods which are provided for stretching or withdrawing the handle with respect to the case, and the bottom of the case has two wheels. The wheels are disposed in the case, and the luggage has a wheel moving means for moving the wheels outwardly from the case or inwardly towards the case when the handle is moved. When the handle is pulled to stretch towards the outside of the case, the wheels are moved outwardly from the case. When the handle is withdrawn towards the case, the wheels are withdrawn inwardly towards the case. With the wheel moving means, the wheels can be moved and stretched or withdrawn to reduce the height of the luggage, so as to facilitate storage.
