ABSTRACT:
The push back storage rack system comprises a framework defining a storage bay for multiple pallets including a plurality of generally vertical uprights and a plurality of generally horizontal shelf beams. A pair of laterally spaced, generally parallel rails is supported by the framework and extends into the storage bay. Each of the rails defines inner and outer wheel tracks and is inclined in a direction towards the rear of the storage bay. A generally rectangular first cart has a pair of front wheels and a pair of rear wheels. The front and rear wheels roll along the inner wheel tracks. The generally rectangular second cart is positioned behind the first cart and has a pair of front wheels and a pair of rear wheels. The front wheels roll along the outer wheel tracks and the rear wheels roll along the inner wheel tracks. A generally rectangular third cart is positioned behind the second cart and has a pair of front wheels and a pair of rear wheels. The front and rear wheels roll long the outer wheel tracks. The third cart supports a second pair of laterally spaced, generally parallel rails, each of which defines an outwardly facing wheel track. The rear of the second pair of rails is supported by a pair of wheels that roll along the inner wheel tracks. A fourth generally rectangular cart is positioned behind the third cart and has a pair of front wheels and a pair of rear wheels. The front wheels roll along the second pair of rails and the rear wheels roll along the outer wheel tracks. The second pair of rails is oriented such that downward forces placed on the front wheels of the fourth cart inhibit development of a horizontal force component tending to move the fourth cart rearwardly into the storage bay.
