Definitions

  • a central barrier according to the invention has a cover member 16, which covers the upper cable 11.
  • On the inside of the cover member there is an undercut groove 17 with opposing mouth flanges 18, 19.
  • a holder element 20 is inserted and attached.
  • the mouth flanges 18, 19 are arranged at different levels.
  • the holder element portion 21, which is intended to be in- serted into the undercut groove has such a shape that it can be obliquely positioned and inserted under the flange 18.
  • the other end of the holder element 20 is Y-shaped to form a cable groove 23. At the aperture end of the groove, there are outwardly directed flanges 24.
  • a clip 25 has corresponding inwardly directed flanges 26 to be able to be mounted on the holder element 20.
  • the clip 25 has a wedge-shaped projection 27, which is directed inwards towards the cable groove 23, when mounting the clip, and which is pressed against the cable 11 and locks the holder element 20 and thus also the cover member 16 in the mounted position.
  • the cover member is provided with inwardly projecting support flanges 28.
  • FIG. 9 shows yet another preferred embodiment of a central barrier according to the present invention.
  • the design of the different parts is substantially the same as in Figs 2-4, except that the parts corresponding to the support flanges 28 have a different design (the details 34 of the cover member 16 and the details 35 of the hub cap impact-absorbing rods or rails 33, respectively) .
  • the support flanges 34, 35 have a more frail construction.
  • the purpose thereof is to provide a construction, in which the impact-absorbing cables, if possible, are prevented from breaking by having the possibility of sliding out of their grooves 13, 14 in the posts 10 upon a very violent collision. The reason for this is that the cables 11, 12, at the best, should hold upon impact and that only the posts near the location of the collision should need to be replaced.
