Patent ID: 8851300

Claim:
A roll-out shelving storage rack system, comprising: a frame; a first shelf member, the shelf member comprising: a base support mounted to the frame, a shelf support tray engaged with the base support and movable between a retracted position and an extended position, a shelf engaged with the shelf support tray and movable between a retracted position and an extended position, and a first driver coupled with the base support and the shelf, wherein actuation of the first driver moves the shelf from its retracted position to its extended position, further wherein, when the shelf reaches its extended position, the shelf support tray moves from its refracted position to its extended position, thereby extending the shelf substantially, completely exterior to the frame; a second shelf member, the second shelf member comprising: a base support mounted to the frame, a shelf support tray engaged with the base support and movable between a retracted position and an extended position, a shelf engaged with the shelf support tray and movable between a retracted position and an extended position, and a second driver coupled with the base support and the shelf, wherein actuation of the second driver moves the shelf from its retracted position to its extended position, further wherein, when the shelf reaches its extended position, the shelf support tray moves from its retracted position to its extended position, thereby extending the shelf substantially, completely exterior to the frame; and a drive system coupled with the first driver and the second driver for moving the first shelf member and the second shelf member between extended and retracted positions, wherein the drive system disables the second driver during extension and retraction of the first shelf member, further wherein the drive system disables the first driver during extension and retraction of the second shelf member, the drive system, comprising: a manifold coupled with a source of pressurized air for distributing pressurized air throughout the drive system, a first start system for the first shelf member, the first start system comprising an “out” push button valve and an “in” push button valve, and a first air valve switch coupled with the first start system, wherein activation of the “out” push button valve of the first start system actuates the first air valve switch such that the first air valve switch operates the first driver of the first shelf member to extend the first shelf member, further wherein activation of the “in” push button of the first start system actuates the first air valve switch such that the first air valve switch operates the first driver of the first shelf member to retract the first shelf member.
