  "abstract": "Beams and posts are disclosed. The beams and posts may be used for racks or shelving. The beams and posts may be formed by folding a sheet of metal. For example, the beams and posts may be non-volumous or hollow. Optionally, a portion of the wall of the beam or post is thickened, for example, by folding over the metal back and forth. Optionally, the thickened portion runs the length of the beam or post. In some embodiments, a fastener (e.g., a loop and/or hook) is formed in the thickened portion of the wall. For example, the fastener formed by punching out of the wall. Optionally, the fasteners are used to connect the posts to the beams.",
  "claims": [
    "1. A bar comprising: a wall on at least one side of the bar and including a thinner portion running an entire length of the wall and a thicker portion running the entire length of the wall, said thicker portion being thicker than said thinner portion; and a fastener punched out from said thicker portion, wherein the bar is hollow and wherein said wall at a location of said fastener is a wall of a hollow of the bar; wherein said thicker portion includes multiple layers of metal folded against each other; wherein said thicker portion includes an odd number of layers.",
    "2. The bar of claim 1, wherein said wall is formed of a single sheet of folded metal.",
    "3. The bar of claim 1, wherein said fasteners include at least one of a hook and a loop.",
    "4. A storage rack comprising: a bar including: a wall forming at least one side of the bar and including a thin portion running an entire length of the wall and a thickened portion running the entire length of the wall, the thickened portion being thicker than a thinner portion of the wall; and a fastener formed in said thickened portion, wherein the bar is hollow and wherein at a location of said fastener said wall is a wall of a hollow of the bar wherein the bar is configured to be positioned horizontally for use as a horizontal beam of the rack and said fastener connects the horizontal beam to an upright post of the rack.",
    "5. The storage rack of claim 4, wherein said thickened portion includes multiple layers of metal folded against each other.",
    "6. The storage rack of claim 4, wherein said wall is formed of a single sheet of folded metal.",
    "7. The storage rack of claim 4, wherein said fasteners include at least one of a hook and a loop.",
    "8. A method of making a bar comprising: supplying a sheet of metal; folding over a portion of the sheet onto itself to form a thickened portion of multiple layers along a full length of the sheet; punching a fastener out of said thickened portion; and further folding the sheet into a bar with said thickened portion running a full length of the bar and said fastener in a wall of the bar, wherein said further folding the sheet into a bar include at least two folds to form a hollow bar with said thickened portion and said fastener in a wall of a hollow of the bar.",
    "9. The method of claim 8, wherein said folding over a portion includes folding back and forth to form a line of multilayered material.",
    "10. The method of claim 8, wherein said further folding the sheet into a bar includes at least two folds to form a hollow cylinder of non-circular cross section.",
    "11. The method of claim 8, wherein said folding over and said further folding the sheet are along parallel folds.",
    "12. The method of claim 8, wherein the bar is a positioned horizontally for use as a horizontal beam of a rack and said fastener connects the horizontal beam to an upright post of the rack.",
    "13. A storage rack comprising: a bar including: a wall forming at least one side of the bar and including a thin portion running an entire length of the wall and a thickened portion running the entire length of the wall, the thickened portion being thicker than a thinner portion of the wall; and a fastener formed in said thickened portion, wherein the bar is hollow and wherein at a location of said fastener said wall is a wall of a hollow of the bar; wherein said thickened portion includes multiple layers of metal folded against each other; wherein said thicker portion includes an odd number of layers.",
    "14. The storage rack of claim 13, wherein said wall is formed of a single sheet of folded metal.",
    "15. The storage rack of claim 13, wherein said fasteners include at least one of a hook and a loop."

  "description_excerpt": "The present invention relates to metal shelving. The construction of pallet racks from components and specifically to joining upright posts with the horizontal beams to form a scaffolding unto which shelves are laid.\n\nThe use of pallet racks is common in warehouses and stores. Such appliances are designed to receive product bearing pallets typically from a forklift truck.\n\nTypically, such racks are constructed from upright posts into which horizontal beams are connected. See for example European patent application EP 3042865A1.\n\nAccording to an aspect of some embodiments of the invention, there is provided a bar including: a thin wall; a thickened portion of the thin wall; a fastener formed in the thickened portion.\n\nAccording to some embodiments of the invention, the thickened portion includes multiple layers of metal folded against each other.\n\nAccording to some embodiments of the invention, the thickened portions run a length of the bar.\n\nAccording to some embodiments of the invention, the bar has a plurality of the walls formed of a single sheet of folded metal.\n\nAccording to some embodiments of the invention, the fasteners include at least one of a hook and a loop.\n\nAccording to an aspect of some embodiments of the invention, there is provided a storage rack including: a bar including: a thin wall; a thickened portion of at the thin wall; a fastener formed in the thickened portion.\n\nAccording to some embodiments of the invention, the thickened portion includes multiple layers of metal folded against each other.",
