Claim 0:
1. An adjustable refrigeration rack system, comprising:
a pair of parallel shafts arranged on a rear interior cabinet side of a refrigerator;
a plurality of pairs of attachment mechanisms, each attachment mechanisms having one attachment mechanism arranged on one rail, and another arranged at equal height on the other rail, the attachment mechanisms configured to hold a shelf and selectively engage the respective shafts,
wherein each attachment mechanism includes a clamping mechanism having two halves, each defining half of a shaft opening and configured to engage the shaft when the halves are in an engaged state, and disengage when the halves are in a disengaged state,
wherein each of the halves of the clamping mechanism define a wall opposite the wall of the other of the halves, the clamping mechanism including a rotatable cam arranged between the walls on a side of the halves and having a lever portion configured to selectively apply pressure to at least one of the walls to push the halves apart, creating a gap between the halves to create the disengaged state; and

a drive mechanism configured to drive the shafts vertically when the clamping mechanism is in the disengaged state, wherein movement of the shafts causes movement of the shelf arranged on the attachment mechanisms selectively engaged with the shafts, but not movement of a shelf arranged on the attachment mechanisms unattached to the shafts.
