Backpack with detachable wheels

Abstract

The present invention relates to backpacks, particularly for use by children and young adults. The backpacks are normally used to transport books and other educational materials to and from educational facilities, such as schools. A plurality of wheels are secured to the bottom or lower portion of the backpack. In a preferred embodiment, the wheels are attached to a frame which is attachable to and removable from the backpack. The wheels and frame are stored on the backpack when not in use, such as when the child is in school. The wheels permit the backpack to be rolled behind a user rather than be carried by the user on their back. Rolling of the backpack avoids physical injuries resulting from carrying the backpacks on the user's back.
