  • Patent number: 5749503
    Abstract: A luggage container which conveniently converts for use as wheeled suitcase, a backpack and a hand-carry bag having a first and second compartment for storage of belongings. A pair of wheels are rotatably mounted to an axle which is at an edge along the bottom of the first compartment. A pair of shoulder straps are provided in the second compartment and are concealed by a cover. When the container is used as a backpack, the cover is opened to reveal the shoulder straps. The cover is wrapped over the wheels and secured to the bottom side of the first compartment. In this manner the traveler and the traveler's belongings are protected when cartage is on the traveler's back from filth that accumulates on the wheels.
