A shelving system for use with a load cell has a frame, to which the load cell is mounted, and a rack residing within the frame and having a load cell proximity surface supported on the load cell by a pivotal contact element. The rack is stabilized by an anti-sway system having three lever arms connected between the frame and the rack and spaced apart from the load cell proximity surface. A first and a second lever arm are parallel and spaced apart from each other, and extend parallel to two faces of the rack, while a third lever arm extends substantially normal to the first and the second lever arms. A fourth lever arm can be provided, located in close proximity to the load cell proximity surface and extending parallel to at least one of the other lever arms.

What is claimed is: 1. A shelving system for use with a load cell, the shelving system storing inventory while the load cell monitors the weight of inventory stored thereon, the shelving system comprising: a frame having a frame height HF and terminating in a first pair of frame faces and being further bounded by a second pair of frame faces, said frame having a frame footprint and having a load cell support platform for attaching and supporting the load cell; a rack having a rack height HR and terminating in a first pair of rack faces separated by a first rack face pair separation distance D1 and further bounded by a second pair of rack faces separated by a second rack face pair separation distance D2, said rack having a rack footprint which resides within said frame footprint, said rack having at least one shelf and a load cell proximity surface; a pivotal contact element for interposing between said load cell proximity surface and the load cell; and an anti-sway and transient damping system having, a first lever arm affixed to said frame and to said rack at first lever arm connection points on said frame and said rack, said first lever arm connection points being spaced apart from each other by a first arm effective length L1, a second lever arm affixed to said frame and to said rack at second lever arm connection points on said frame and said rack, said second lever arm connection points being spaced apart from each other by a second arm effective length L2, said first and second lever arms being substantially parallel to each other and to said second pair of frame faces and being spaced apart from each other by an arm separation SA, a third lever arm affixed to said frame and to said rack at third lever arm connection points on said frame and said rack, said third lever arm connection points being spaced apart from each other by a third arm effective length L3, said third lever arm extending substantially normal to said first lever arm and said second lever arm, said first lever arm, said second lever arm, and said third lever arm being spaced apart with respect to said load cell proximity surface such that the closest of said lever arms resides at a substantial minimum vertical separation SV from said load cell proximity surface. 2. The shelving system of claim 1 further comprising: a fourth lever arm affixed to said frame and to said rack at fourth lever arm connection points on said frame and said rack, said fourth lever arm connection points being spaced apart from each other by a fourth arm effective length L4, said fourth lever arm being substantially parallel to at least one of said first lever arm, said second arm, and said third lever arm, said fourth lever arm being positioned in close proximity to a horizontal plane in which said load cell proximity surface resides. 3. The shelving system of claim 2 wherein the load cell is attached to said load cell support platform such that the attachment resides between said fourth lever arm and said pivotal contact element. 4. The shelving system of claim 2 wherein said fourth lever arm is substantially parallel to said first lever arm. 5. The shelving system of claim 4 wherein the load cell is attached to said load cell support platform such that the attachment resides between said fourth lever arm and said pivotal contact element. 6. The shelving system of claim 1 wherein said at least one shelf of said rack includes a lower shelf, further wherein said first, second, and third lever arms are located in close proximity to said lower shelf of said rack, said rack further comprising: an upper cross member residing in a top region of said frame, said load cell proximity surface being provided on said upper cross member. 7. The shelving system of claim 1 wherein said at least one shelf of said rack includes a lower shelf, further wherein said first, second, and third lever arms are substantially displaced from said lower shelf of said rack, and further wherein said load cell proximity surface resides below said lower shelf of said rack. 8. The shelving system of claim 2 wherein said at least one shelf of said rack includes a lower shelf, further wherein said first, second, and third lever arms are located in close proximity to said lower shelf of said rack, the rack further comprising: an upper cross member residing in a top region of said frame, said load cell proximity surface being provided on said upper cross member. 9. The shelving system of claim 2 wherein said at least one shelf of said rack includes a lower shelf, further wherein said first, second, and third lever arms are substantially displaced from said lower shelf of said rack, and further wherein said load cell proximity surface resides below said lower shelf of said rack. 10. The shelving system of claim 1 wherein said first lever arm, said second lever arm and said third lever arm are parallel to a common plane, and still further wherein said arm separation SA is greater than about �� of said second rack face pair separation distance D2. 11. The shelving system of claim 10 wherein said minimum vertical separation SV is at least about �� of said rack height HR. 12. The shelving system of claim 11 wherein said first arm effective length L1, said second arm effective length L2, and said third arm effective length L3 are each at least about �� of the minimum of said first rack face pair separation distance D1 and said second rack face pair separation distance D2. 13. The shelving system of claim 12 further comprising: a fourth lever arm affixed to said rack and to said frame at fourth lever arm connection points on said frame and said rack, said fourth lever arm connection points being spaced apart from each other by a fourth arm effective length L4 that is at least about �� of the minimum of said first rack face pair separation distance D1 and said second rack face pair separation distance D2, said fourth lever arm being substantially parallel to at least one of said first lever arm, said second arm and said third lever arm, said fourth lever arm being positioned in close proximity to a horizontal plane in which said load cell proximity surface resides. 14. The shelving system of claim 1 wherein said first pair of frame faces form a frame front face and a frame rear face of said frame, said frame front face having an opening to allow access to said rack. 15. The shelving system of claim 2 wherein said first pair of frame faces form a frame front face and a frame rear face of said frame, said frame front face having an opening to allow access to said rack. 16. The shelving system of claim 1 wherein all of said lever arms are cylindrical. 17. The shelving system of claim 2 wherein all of said lever arms are cylindrical. 18. The shelving system of claim 10 wherein all of said lever arms are cylindrical. 19. The shelving system of claim 11 wherein all of said lever arms are cylindrical. 20. The shelving system of claim 13 wherein all of said lever arms are cylindrical.
