Definitions

  • the invention relates to a hollow post with an accompanying mounting element for securing wires, pipes, mesh panels constructed of wire, etc. to the post, in which the post is provided with at least one aperture and in which the mounting element is provided, on the one hand, with a connecting pin specially adapted to the aperture with longitudinal openings for the formation of movable wedges or legs and, on the other hand, with a longitudinal bore hole and an accompanying nail specially adapted to the bore hole for securing the pin in the aperture.
  • Such a hollow post with an accompanying mounting element is known from the German patent 2.231.337.
  • Such hollow posts are usually constructed out of thin-walled pipe or plate material having a thickness of a few millimetres.
  • the introduction of apertures, even with accompanying mounting elements, in such a hollow post has the disadvantage that rainwater can get into the hollow post via the apertures, with all the consequent damage, such as rusting of the post, cracking of the post from freezing, etc., which considerably shortens the lifespan of the post.
  • the invention presents a hollow post with an accompanying mounting element of the type described in the introduction, in which the aperture is provided with a bushing connected to it and in which the longitudinal openings in the connecting pin extend only over a part of the length of the pin, such that the pin is provided at its base with a closure section for its insertion into the bushing.
  • Each aperture and the bushing which forms one piece with it are by preference produced by flow-drilling.
  • the process of flow-drilling which has been known for a long time, is used to produce bushing-shaped apertures in thin-walled metal workpieces, such as posts.
  • Figure 1 shows in perspective a hollow post 1 with an accompanying mounting element 2.
  • the use of hollow metal posts 1 with accompanying mounting elements 2 for securing wires, pipes and mesh panels constructed of wire to the posts 1 is generally known.
  • the hollow post 1 is by preference constructed of a thin-walled pipe or plate material having a thickness of a few millimetres.
  • the thickness of the plate material is, for example, between 1 and 4 mm, and by preference between 1.5 and 2.5 mm.
  • the mounting element 2 is by preference constructed of a plastic, such as polyamide.
  • the hollow post 1 is provided with the necessary apertures 3 for securing the mounting elements 2 to the post 1.
  • each mounting element 2 is provided with a connecting pin 4 specially adapted to the aperture 3, or, in other words, the diameter of the pin 4 is for all intents and purposes equal to the diameter of the aperture 3.
  • the diameter of the aperture 3 and the accompanying pin 4 vary, for example, between 10 and 20 mm, and by preference between 12 and 16 mm.
  • the connecting pin 4 is provided with four openings 5 which are oriented longitudinally in the form of a cross and are intended to form four wedges or legs 6 that will move under pressure.
  • the mounting element 2 is provided with a longitudinal bore hole 7 with an accompanying nail 8 which is specially adapted to the bore hole for the purpose of securing the connecting pin 4 in the accompanying aperture 3.
  • the mounting element 2 represented in Figure 1 exhibits two vertical longitudinal grooves 9 through which the vertical wires on the edges of the two wire panels to be secured to the post 1 are to pass. It is evident that the mounting element 2 can also be provided with other grooves or other means for holding wires, pipes, etc.
  • the aperture 3 is provided with a bushing 10 which forms one piece with it and which is of the same diameter as the diameter of the aperture 3.
  • the height of the bushing 10 is preferably equal to between two and four times the thickness of the plate, which means for example that it is between 3 and 6 mm for a plate thickness of 1.5 mm.
  • the aperture 3, the bushing 10 and the sealing rim of the aperture 3 are by preference produced in the post 1 in one operation, as with the already known flow-drilling process.
  • the flow-drilling process is a method in which apertures in the form of bushings are produced in thin-walled metal workpieces by means of flow-drilling; in other words, the flow-drilling process makes it possible to bore apertures 3 in thin-walled metal posts 1 without removing metal, while at the same time forming a bushing 10.
  • the longitudinal openings 5 in the connecting pin 4 which form the four movable wedges or legs 6 run only over a part of the length of the pin 4, such that the connecting pin 4 is provided at its base with a closure section 11 with an entirely closed circumference having a height of a few millimetres.
  • Figures 2a, 2b and 2c show in cross-section the consecutive phases of the process of securing the mounting element 2 on the post 1.
  • Figure 2a shows in cross-section the mounting element 2 with the nail 8 in the accompanying longitudinal bore hole 7 before the introduction of the connecting pin 4 into the accompanying aperture 3. It is clear from Figure 2a that between the four wedge-shaped legs 6 a cone-shaped opening or cavity 12 has been introduced to receive the pointed end of the nail 8.
  • Figure 2b shows the mounting element 2, with the connecting pin 4 already fully settled in the aperture 3 and the bushing 10, but before the nail 8 has been completely driven into the longitudinal bore hole 7.
  • Figure 2b clearly shows that the legs or wedges 6 have not yet been deformed.
  • the bushing 10 and the closure section 11 must fit well into one another or overlap one another over a sufficient distance of a few millimetres to obtain a watertight seal of the pin 4 in the bushing 10.
  • the longitudinal openings 5 now run up to the bushing 10 or even for a small distance into the bushing 10.
  • Figure 2c shows the mounting element 2, with the nail 8 completely driven into the element 2.
  • the legs or wedges 6 are greatly displaced or deformed, which results in the mounting element 2 being firmly secured in the aperture 3 and the bushing 10.
