A multi-position display rack includes first and second sides having parallel mounting faces and front and rear columns of spaced apertures aligned in opposition to define front and rear sets of apertures. A removable shelf is adapted to be supported between the first and second sides and includes a frame having front and rear hooks. The front hooks are connected to the frame for rotative and sliding movement within an adjustment zone. Support elements extend through the adjustment zone and contact the front hooks to transfer loads from the shelf to the first and second sides. The rear hooks lock the shelf to a set of rear apertures and the front hooks may engage a plurality of selected sets of front apertures.

The storage apparatus of claim 5 wherein the elongated track has a back side positioned adjacent to the wall and an opposite front side, wherein the support mechanism has a front end located at the front side of the elongated track and a back end located at the back side of the elongated track, and wherein between the first and second ends, the cable is coupled to the back end of the support mechanism.8. The storage apparatus of claim 7 wherein between the first and second ends, the cable is further coupled to the front end of the support mechanism.9. The storage apparatus of claim 8 wherein the support mechanism has a horizontal centerline, wherein the cable is coupled to the front end of the support mechanism above the horizontal centerline, and wherein the cable is coupled to the back end of the support mechanism below the horizontal centerline.10. The storage apparatus of claim 8 wherein the front end of the support mechanism includes a front pulley, wherein the back end of the support mechanism includes a back pulley, and wherein between the first and second ends the cable passes over the front and back pulleys.11. The storage apparatus of claim 10 wherein the upper end of the elongated track includes a track pulley, and wherein between the front pulley and the back pulley the cable passes over the track pulley.12. The storage apparatus of claim 8 wherein the drive drum has a drive surface such that the cable, between the first and second ends, passes over the drive surface defining a friction drive region between the drive surface and the cable, the friction drive region, when the object on the support mechanism does not exceed the maximum weight limit of the storage apparatus, providing sufficient frictional interaction between the drive surface of the drive drum and the cable, such that rotation of the drive drum moves the cable to thereby move the support mechanism between the loading and storage positions, and the friction drive region, when the object on the support mechanism does exceed the maximum weight limit of the storage apparatus, providing insufficient frictional interaction between the drive surface of the drive drum and the cable, such that upon rotation of the drive drum, the drive surface slips relative to the cable preventing movement of the support mechanism between the loading and storage positions.13. The storage apparatus of claim 12 wherein the drive assembly further includes: a crank releasably engageable with the drive drum, the crank when engaged with the drive drum allowing a user to turn the crank thereby rotating the drive drum. 14. The storage apparatus of claim 12 wherein the drive surface is a cylindrical drum surface of the drive drum, and wherein between the first and second ends, the cable passes over the cylindrical drum surface at least one time.15. The storage apparatus of claim 14 wherein between the first and second ends the cable passes over the cylindrical drum surface three times.16. The storage apparatus of claim 15 wherein the cylindrical drum surface includes three grooves for receiving the cable to define the friction drive region between the drum surface and the cable.17. The storage apparatus of claim 16 wherein the drive mechanism further includes: a second drive pulleys rotatably mounted to the elongated track, wherein the cable, between the first and second ends, passes over the first and second drive pulleys. 18. The storage apparatus of claim 17 wherein the cable passes over one of the first and second drive pulleys between adjacent cable passes over the drum surface of the drive drum.19. The storage apparatus of claim 14 wherein the drive assembly further includes: means for tensioning the cable about the drum surface of the drive drum to create the friction drive region between the drum surface and the cable. 20. The storage apparatus of claim 19 wherein tensioning means includes a movable threaded fastener en
