Abstract
In a storage system comprising rows of shelves defining lanes for the storage of cartons or pallet loads and like wherein the shelf lanes are adapted to receive inventory loads one behind the other, a push-pack system comprising a pair of track adapted for wheels to roll upon the inner and outer edges of the top surface thereof, a first cart with a rectangular frame with wheels to ride on one edge of the tracks, a second cart having a U-shaped frame adapted to receive the first cart nested within the frame at approximately the same elevation and having wheels to ride upon the other edges of the track. Variations may provide for three or four carts providing storage of loads four or five pallets deep.

In a storage system comprising rows of shelves defining lanes for the storage of cartons, pallet loads, and packages, wherein the shelf lanes having front and back ends are adapted to receive more than one load of inventory positional one behind the other from front to back, a push-back system comprising;
- at least one pair of tracks running from front to back in each shelf lane, each track having a substantially flat horizontal top surface for wheels to roll upon, and having inside edges facing a center of said lane and outside edges facing sides of said lane;
- a first cart having a rectangular shaped frame and having at least one wheel on each side mounted to said frame and adapted to roll on the top of each said track;
- a second cart adapted to move relative to said first cart and having a U-shaped frame open at one end to permit said first cart to nest within said second cart frame, and having at least one wheel on each side adapted to run along the top of each of said tracks respectively;
- the wheels of one cart being adapted to run along the inside edges of said tracks and the wheels of the other cart being adapted to roll along the outside edges of said tracks;
- the top surface of said tracks being wide enough to permit wheels on the inside and outside edges to pass without colliding.
A system as claimed in clam 3 in which said wheels have vertical flanges adapted to bear against and maintain said wheels adjacent to the respective inner and outer edges of the top surface of said vertical track respectively, and said tracks have vertical flanges adjacent to the track edges on the opposite side of said wheel flanges from said track edges to prevent said wheels running off the top surface of said tracks.
