The backpack with retractable handle and wheels comprises an extendable handle, a plurality of wheel mechanisms and a luggage item. The luggage item is modified to further comprise a center channel, a grip aperture, a plurality of wheel cavities, and a plurality of wheel covers. The extendable handle is stored within the center channel. The extendable handle projects through the grip aperture such that the extendable handle may be withdrawn from the center channel. The backpack with retractable handle and wheels is designed such that each of the plurality of wheel mechanisms is stored in a wheel cavity selected from the plurality of wheel cavities. Each of the plurality of wheel mechanisms is mechanically linked to the extendable handle such that when the extendable handle is withdrawn from the center channel each of the plurality of wheels extends out of its corresponding wheel channel.

1. A container with a retractable rolling device comprising: an extendable handle, a plurality of wheel mechanisms and a luggage item;wherein the luggage item comprises a center channel, a grip aperture, a plurality of wheel cavities, and a plurality of wheel covers;wherein the extendable handle is a handle that is stored within the center channel;wherein the grip aperture is located the top of the luggage item;wherein the plurality of wheel cavities are formed at the bottom of the luggage item;wherein the extendable handle projects through the grip aperture such that the extendable handle may be withdrawn from the center channel such that the extendable handle projects into the exterior space of the luggage item;wherein each of the plurality of wheel mechanisms is stored in a wheel cavity selected from the plurality of wheel cavities;wherein each of the plurality of wheel mechanisms is mechanically linked to the extendable handle such that when the extendable handle is withdrawn from the center channel each of the plurality of wheel mechanisms extends out of its corresponding wheel cavity into the exterior space of the luggage item;wherein each of the plurality of wheel covers encloses a wheel cavity selected from the plurality of wheel cavities;wherein the extendable handle comprises a shaft, a grip, and a cross brace;wherein the shaft is a first member that is further defined with a first end and a second end;wherein the cross brace is a third member that is further defined with a third end and a fourth end;wherein the grip is a second member;the first end of the shaft attaches to the center of the grip such that the center axis of the grip is perpendicular to the center axis of the shaft;wherein the second end of the shaft attaches to the cross brace such that the center axis of the cross brace is perpendicular to the center axis of the shaft;wherein the center channel is an enclosed cavity that is formed within the luggage item;wherein the extendable handle is contained within the center channel;wherein the end of the center channel that is proximal to the first end of the shaft contains the grip aperture;wherein the grip aperture is an aperture that is sized to allow the shaft to be inserted through the grip aperture;wherein the grip is attached to the first shaft on the exterior side of the grip aperture;wherein each of the plurality of wheel mechanisms comprises a collection of individual wheel mechanisms;wherein each of the plurality of wheel mechanisms are identical;wherein each of the plurality of wheel cavities is a cavity that is formed in the luggage item such that each of the plurality of wheel cavities is accessible from the exterior of the luggage item;wherein each individual wheel mechanism is installed in a wheel cavity selected from the plurality of wheel cavities;wherein each individual wheel mechanism comprises a wheel, a wheel mount, a pivot, a pulley, a cable, and a spring;wherein the cable is a cord that is further defined with a fifth end and a sixth end;wherein the spring is further defined with a seventh end and an eighth end;wherein the wheel, the pulley, the cable, and the spring are attached to the wheel mount;wherein the wheel is mounted in the wheel mount such that the wheel can rotate freely within the wheel mount;wherein the wheel mount is a mounting structure that further comprises a fork, an axle shaft, and a rotating shaft;wherein the axle shaft attaches the wheel to the wheel mount;wherein the ends of the rotating shaft are attached to the interior walls of the selected wheel cavity associated with the individual wheel mechanism;wherein the fork comprises two parallel plates between which the wheel is inserted such that the arc of rotation of wheel is parallel to the planes of the two parallel plates;wherein the two parallel plates of the fork attach to each other using the rotating shaft such that the fork will rotate around the center axis of the rotating shaft;wherein the rotating shaft forms the pivot around which the individual wheel mechanism will rotate to extend the wheel mount and wheel out of the selected wheel cavity;wherein a pulley is attached to the fork such that the pulley fits around the rotating shaft;wherein a pulley is attached to the fork such that the center axis of the pulley is aligned with the center axis of the rotating shaft. 2. The container with a retractable rolling device according to claim 1wherein the fifth end of the cable is attached to an end of the cross brace selected from the group consisting of the third end and the fourth end;wherein the sixth end of the cable is attached to the fork of the wheel mount. 3. The container with a retractable rolling device according to claim 2 wherein when the wheel mount is in the retracted position the cable is looped around the pulley such that the linear direction of the cable is changed. 4. The container with a retractable rolling device according to claim 3 wherein the cable rotates the wheel mount around the pivot formed by the rotating shaft in a manner that extends the wheel mount and the wheel into the exterior space beyond the luggage item. 5. The container with a retractable rolling device according to claim 4wherein the spring is a tension spring;wherein the seventh end of the spring is attached to the fork;wherein the eighth end of the spring is attached to an interior surface of the selected wheel cavity;wherein the spring pulls the wheel mount back into the selected wheel cavity. 6. The container with a retractable rolling device according to claim 5 wherein each of the plurality of wheel covers is a textile flap that is attached to the luggage item such that the individual wheel mechanism can be enclosed within the selected wheel cavity by the selected wheel cover. 7. The container with a retractable rolling device according to claim 6wherein each selected wheel cover is secured over the selected wheel cavity using a fastener;wherein the fastener is selected from the group consisting of a zipper, a snap, or a hook and loop fastener. 8. The container with a retractable rolling device according to claim 7wherein the plurality of wheel mechanisms comprises a left wheel mechanism and a right wheel mechanism;wherein the plurality of wheel cavities comprises a left wheel cavity and a right wheel cavity;wherein the plurality of wheel covers comprises a left wheel cover and a right wheel cover;wherein a snap is used as the fastener for each of the plurality of wheel covers;wherein the cable is formed from a metal wire. 9. The container with a retractable rolling device according to claim 8 wherein the luggage item is selected from the group consisting of a trunk, a suitcase, or a backpack. 10. The container with a retractable rolling device according to claim 8 wherein the luggage item is a backpack. 11. The container with a retractable rolling device according to claim 10wherein the interior space of the backpack is further subdivided into a plurality of storage compartments comprising a main compartment, a secondary compartment, and a front compartment;wherein the exterior surface of the backpack is further fitted with a plurality of pockets for the purpose of providing readily accessible storage locations;wherein the exterior surface of the backpack is further fitted with a first pocket, a second pocket, a third pocket and a mesh pocket;wherein the backpack further comprises a first shoulder strap and a second shoulder strap;wherein the backpack further comprises a fixed handle.
