Definitions

  • the present invention relates to an improved star picket which is provided with a novel arrangement for the attachment of wires and the like from one star picket to another.
  • the present invention is directed to star pickets made of plastics material which include this novel attachment means.
  • Star pickets are well known in the field. They are typically constructed from steel and have proved to be a convenient, effective and relative inexpensive product for use in a number of applications, and in particular, fencing. As is well known the commonly available star picket consists of a core and three radially extending, substantially equally spaced webs. Typically, at least one of the webs is provided with number of holes through which fencing wire is passed or attached to the picket in the formation of a fence.
  • the present inventor has developed a star picket which includes a novel mean of attaching fencing wire (or any other flexible or deformable strip material) to the picket.
  • the present invention consists in an elongate star picket comprising a core and at least three radially extending substantially equally spaced apart webs, wherein one ore more of the webs is provided with at least one attachment means, the attachment means comprising at least one slot extending from an outer edge of the web and a hole positioned near the slot and extending through the web.
  • the attachment means has two slots spaced apart in the longitudinal direction of the web, and wherein the hole is intermediate the two slots.
  • a pin is provided in the hole, the pin extending on either side of the web.
  • the slots are enlarged at one end digital from the edge of the web, the enlargement being on a side of each slot which is closest to the hole.
  • the improved star picket includes a plurality of the attachment means, each being provided at spaced locations along the same web.
  • the improved star picket and the pin are formed of a plastics material. Any plastics material may be used, however, it is presently preferred that the plastics material is recycled PET.
  • a plurality of cavities are provided in the webs along an end portion of the star picket which is to be driven to the ground. These cavities are of particular use where the star picket is formed of plastics material and is to be set in concrete as there is very little bonding of concrete to plastic. The cavities cause the picket to be interlocked with the concrete.
  • the star picket 10 consists of a core portion 12 and three radially extending webs 14, 16 and 18. Web 16 is provided with attachment means generally shown as 20.
  • the attachment means 20 consists of two generally L-shaped slots 22 and 24 and hole 26 in which is provided pin 28.
  • the slots 22, 24 extend from the outside edge 29 of the web 16 towards the core portion 12 and are spaced apart a short distance along the length of the web 16.
  • the hole 26 is provided intermediate the slots 22, 24.
  • the ends 30, 31 of the slots 22, 24 are enlarged in the direction towards the hole 26. Further, the enlarged ends 30, 31 are generally aligned with the hole 26.
  • fencing wire 28 can be readily attached to the star picket 10 without the need to thread the wire 28 through a hole provided in the star picket 10.
  • the wire is passed through slot 24, around pin 27 over the edge 29 of web 16 around pin 27 once again and then through slot 22.
  • attachment of wire to the star picket of the present invention is much simpler than attachment of wire to presently available star pickets. That is, the attachment means 20 provides an easy and effective means of securely attaching a wire or other flexible filament to the picket 10.
  • the attachment means consists of a single slot and a hole which is provided with a pin.
  • the slot is similar to either of slots 22 or 24 described above and the hole and pin are essentially the same as the hole 26 and pin 27 described above.
  • fencing wire can be attached to the star picket by passing the wire from one side of the web 16 through the slot to the other side of the web 16, around the pin, over the edge 29 of the web 16, around the pin once again, and then back through the slot to the other side of the web 16.
  • the star picket of the present invention when forms of plastics material is ideally suited for electrified fencing where the gauge of wire used is less than in other applications. This small gauge wire makes it even easier to pass the wire through this attachment means provided on the picket.
  • the picket 10 is also provided with a number of cavities 32 along an end portion 33 of the picket 10 which is to be driven into the ground.
  • the cavities 32 enable the picket 10 to be securely located in a concrete footing (not shown) in that the concrete is caused to extend through the cavities 32. The picket 10 is thereby interlocked with the concrete footing.
