Definitions

  • This invention relates to an improved connector or buckle for securing the opposite ends of a flexible strap loop which is arranged in taut relation about a package, bail, box or bundle or other object that is to be tied.
  • nonmetallic strapping such as nylon, polypropylene, rayon and the like, whether in rope or cord configuration, or band or strap configuration
  • fasteners or buckles for securing and tensioning the opposite ends, particularly of strap loops, by means of frictional engagement rather than by means of strapping and sealing tools.
  • fasteners or buckles have emerged for non-metallic strapping; those made from a rigid or semi-rigid molded plastic material and those made from spring wire steel. Both types have serious limitations which have unduly limited the full exploitation of the unique advantages of plastic strapping over steel strapping.
  • the invention therefore contemplates a buckle for use in connection with flexible strapping comprising a single piece of wire formed as follows:
  • a second generally U shaped portion including a distal leg formed from the other end of said single piece of wire, a proximal leg, and a bight;
  • FIG. 1 is a plan view of the embodiment of the invention
  • FIG. 2 is a section through the buckle of FIG. 1 along lines 2-2;
  • FIG. 3 is a side elevation of the buckle laced with strap material.
  • a buckle 10' includes a first generally U-shaped portion 1'1, slightly distorted, with distal leg 12, proximal leg 13 and doglegged bight 14.
  • the doglegged bight 14 has two portions 21 and 22 interconnected by a third portion 23 which is disposed essentially parallel to the proximal leg 13 so that a seat or notch 24 is established.
  • a second generally U-shaped portion 15 includes a distal leg 16, proximal leg 17 and bight 18.
  • An intermediate wire portion 19 connects the proximal legs 13 and 17 into a U-shaped planar portion. -It should be noted that the distal leg 16 and bight 18 are in different parallel planes (see FIG.
  • the interjoining bend 27, between distal leg 16 and bight 18 is preferably in a plane perpendicular to the plane of the distal leg 16 and bight 18.
  • the bend 27 is snug to the seat 24. It is this snug relationship between the seat 24 and the bend 27, and the fact that the distal legs 12 and 16 extend across the intermediate wire portion 19 which constrains the distal legs to retain parallelism each to the other as well as to the proximal legs 17 and 13.
  • the distal legs 12 and 16 lie in one plane while the proximal legs 17 and 13 lie in a superadjacent parallel plane which is almost coincident with the first plane such that the distal leg 12 lies essentially superadjacent to the second proximal leg 17.
  • the second distal leg 16 lies essentially superadjacent to the first proximal leg 13. It can also be seen that the distal legs 12 and 16 are disposed nearer to each other than proximal legs 13 and 17 and preferably nearer to each other by the diameter thickness of the wire used to form the buckle itself.
  • the free end 51 of a strip 50 is thread over the distal leg 12 and thence disposed between the distal leg 12 and the adjacent proximal leg 17 and thence beneath and around the proximal leg 17 to overlie the strap 50 essentially as shown in the right hand portion of FIG. 3 wherein the strap 50 is shown in its tight position about the distal leg 12.
  • the end 51 of the strap should extend at least about one inch beyond the buckle 10 in order to provide sufficient free strap should there be flexing of the buckle 10 and stretching of the strap 50 during tightening.
  • the other end of the strap 50 after having been looped about a package (not shown) which is to be tied, is threaded over the other proximal leg 13 and thence between the proximal leg 13 and its adjacent distal leg 16 as more particularly shown in the left hand portion of FIG. 3.
  • a buckle for use in connection with flexible strapping comprising a single piece of Wire formed as follows:
