A device for supporting consumer products includes a transmission, a first end plate, a second end plate, and a shelf. The transmission includes a worm wheel coupled to a socket; a worm gear engaged to the worm wheel and coupled to a back axle shaft; a first pinion gear coupled to a first end of the back axle shaft; and a second pinion gear coupled to a second end of the back axle shaft. The first end plate is coupled to a first end of a back axle shaft shroud, where the back axle shaft shroud includes a first shelf hook and a second shelf hook. The second end plate coupled to the second end of the back axle shaft. The shelf is coupled to the first and second end plates and includes a first and a second shelf pin.

1. An adjustable shelving system for supporting consumer products, comprising: a support frame comprising: a base structure;a first vertical support member coupled to the base structure, the first vertical support member comprising a first vertical rack gear;a second vertical support member coupled
1. An adjustable shelving system for supporting consumer products, comprising: a support frame comprising: a base structure;a first vertical support member coupled to the base structure, the first vertical support member comprising a first vertical rack gear;a second vertical support member coupled to the base structure adjacent the first vertical support member, the second vertical support member comprising a second vertical rack gear; anda third vertical support member coupled to the base structure adjacent the second vertical support member, the third vertical support member comprising a third vertical rack gear, each of the first, second, and third vertical rack gear comprising a base end and a top end;a first adjustable shelf assembly comprising: a first transmission module coupled to the first and second vertical rack gears, the first transmission module adapted to traverse the first and second vertical rack gears; anda first shelf coupled to the first transmission module;a second adjustable shelf assembly comprising: a second transmission module coupled to the first and second vertical rack gears, the second transmission module adapted to traverse the first and second vertical rack gears independently of the first transmission module at substantially infinite intermediate positions between the base ends and the top ends of the first and second vertical rack gears; anda second shelf coupled to the second transmission module; anda third adjustable shelf assembly, the third adjustable shelf assembly comprising: a third transmission module coupled to the second and third vertical rack gears, the third transmission module adapted to traverse the second vertical rack gear independently of the first and the second transmission modules at all intermediate positions between the base end and the top end of the second vertical rack gear; anda third shelf coupled to the third transmission module. 2. The system of claim 1, wherein the second transmission module is adapted to decouple from the first and second vertical rack gears independently of the first transmission module. 3. The system of claim 1, wherein a topside of at least one of the first shelf, the second shelf, or the third shelf is adapted to be disposed at an angle of less than 90 degrees from substantially downward vertical. 4. The system of claim 1, wherein the first shelf is adapted to vertically traverse the support frame using a single point of control through substantially infinite increments between a first end of the support frame and a second end of the support frame without unloading one or more consumer products from a topside of the shelf. 5. The system of claim 4, wherein the single point of control comprises a ratchet socket. 6. The system of claim 5, further comprising a ratchet handle detachably coupled to the ratchet socket. 7. The system of claim 5, wherein the first shelf comprises a front edge and a back edge, the ratchet socket accessible through the first shelf substantially proximate to the back edge. 8. The system of claim 7, further comprising a drive extension coupled to the ratchet socket and longitudinally extended proximate to the back edge. 9. The system of claim 8, wherein the first transmission module is adapted to fail at a first load, and the drive extension further comprises: a stem;a detent coupled to the stem, the detent adapted to secure the stem within the ratchet socket; anda cap coupled to the stem and adapted to receive a ratchet drive, the cap comprising a shear pin, the shear pin adapted to fail at a second load, the second load less than the first load. 10. The system of claim 1, wherein the adjustable shelving system is adapted to support consumer products located in a walk-in cooler. 11. The system of claim 1, wherein the first shelf is a cantilevered adjustable shelf. 12. The system of claim 1, wherein the first transmission module comprises: a worm wheel coupled to a ratchet socket;a worm gear engaged to the worm wheel and coupled to a back axle shaft;a first pinion gear coupled to a first end of the back axle shaft; anda second pinion gear coupled to a second end of the back axle shaft. 13. The system of claim 12, wherein the first pinion gear is adapted to engage the first vertical rack gear and the second pinion gear adapted to engage the second vertical rack gear. 14. The system of claim 12, wherein the first shelf is adapted to support a maximum load of approximately 200 pounds, the worm gear comprising a self-locking worm gear adapted to maintain the first and second pinion gears engaged with the first and second vertical rack gears at a static position at the maximum load. 15. The system of claim 12, wherein the worm gear comprises a worm gear with a ratio between and including about 3:1 to about 10:1. 16. The system of claim 1, wherein the first vertical support member comprises a vertical rib, the first adjustable shelf assembly further comprising a slide bearing that comprises a grooved edge and a chamfered edge, the grooved edge rotatably engageable with the vertical rib.
