It will further be appreciated that the length of each retaining member is substantially the same as the height of the panels
  • a locking arrangement may be provided for locking each retaining member to its associated post.
  • the locking arrangement may comprise having the channel formations dimensioned such that they are an interference fit over the lip formation and fencing panel edge portion combinations, such that they have to be forced over their associated lip formation and fencing panel edge portion combinations and are not easily removable therefrom.
  • the locking arrangement may comprise a screw threaded bolt engageable with a complementary engaging formation in or on an associated retaining member, a head of the bolt being engageable with the inwardly facing external surface of the inner wall of the post. It will be appreciated that holes will be provided in the inner wall through which shanks of the bolts pass, in use.
  • the complementary engaging formation may be a longitudinally extending groove on an inner side of each retaining member. Each groove may have a plurality of longitudinally extending ribs to facilitate locking engagement of the screw threads of the bolts with the groove.
  • Each fencing panel may have a vertically oriented edge bar at each lateral end.
  • Each edge bar may then, in use, be positioned adjacent an inner edge of its associated lip formation, with end regions of the horizontal bars being in contact with the outer surfaces of their associated lip formation.
  • a number of cleats may be provided, that are securable to the lip formations, when the fencing panel edge portions are in position and before the retaining members are engaged therewith, to hold the fencing panel edge portions in place, when the retaining members are engaged over the lip formation and fencing panel edge portion combinations.

  • Figure 5 shows a cross sectioned view of a post, edge portions of fencing panels and a second embodiment of a retaining member.
  • a length of fence in accordance with the invention is designated generally by reference numeral 10.
  • the fence has a plurality of posts 12 with wire mesh fencing panels 14 secured between them by means of retaining members 16.
  • Each post 12 is of mild steel, being hollow and defining a lipped channel profile.
  • each post 12 has two opposed lip formations 18 that face one another, with an outer surface 20 of the lip formations 18 of each post 12 being substantially coplanar.
  • the lip formations 18 extend vertically, in use.
  • the wire mesh fencing panels 14 have a number of horizontal bars 22 and vertical bars 24. There is a vertical bar 24 at each end of each panel 14.
  • the retaining members 16 have a pair of opposed channels 26, with each channel 26 being defined by an inner side wall 28, a base 30 and an outer side wall 32. Each outer side wall 32 has an outer surface 34.
  • the two channels 26 are connected by a bridge 36 that is aligned with the outer side walls 32, such that the outer surfaces 34 of the two outer side walls 32 and the bridge 36 define a planar surface.
  • the ends of the outer side walls 32 have lips 38 for attaching signage (not shown) to the retaining members 16.
  • Cleats 40 are optionally provided to hold edge portions of the fencing panels 14 in position on the outer surfaces 34 whilst the channels 26 of the retaining members 16 are slid over the lip formations 18 with the edge portions of the fencing panels 14 in contact therewith, as is explained below.
  • Caps 42 are provided to close off the upper ends of the posts 12.
  • lower end regions of the posts 12 are anchored in the ground 44 in predetermined spaced apart positions as determined by the widths of the fencing panels 14, with their lip formations 18 extending vertically and with their lip formations facing outwardly.
  • Edge portions of a fencing panel 14 are brought into contact with the respective outer surfaces 20 of adjacent posts 12, with the end bars 24 lying against the inner edges of their associated lip formations 18.
  • the cleats 40 are placed in position, between horizontal bars 22, with their tips engaging the vertical end bars and secured to the outer side walls 32 by screws 46.
  • a retaining member 16 When edge portions have been secured to both lip formations 18 of a post 12 a retaining member 16 is positioned above the post with its channels 26 aligned with the lip formations 18 and its lips 38 outside, and it is slid downwardly over the lip formations 18 and the edge portions secured thereto, such that the channels 26 retain the edge portions against their associated lip formations 18, the lip formations 18 and edge portions being held between the inner and outer side walls 30, 32.
  • the gap between the inner and outer side walls 30, 32 is dimensioned so that the lip formations 18 and edge portions are an interference fit therein, thereby providing a locking arrangement.
  • a degree of force is required to move the retaining members down over the lip formations 18 and edge portions and it is difficult to remove them.
  • FIG. 5 a second embodiment of a retaining member 16 is shown, which uses a different locking arrangement.
  • the bridge 36 has a longitudinally extending inner groove 39 with longitudinal ribs 41 on the inner surfaces thereof and the gap between the inner and outer side walls 30, 32 is dimensioned so that the lip formations 18 and edge portions are a snug fit therein, so that the retaining members 16 may more easily be slid into position and removed therefrom.
  • the retaining members 16 are locked in place by bolts 48 that are inserted into holes 50 provided in an inner wall 52 of the posts 12 with heads 54 of the bolts engaging an inwardly facing external surface 56 of the relevant inner wall 52.
  • Screw threaded shank portions 58 of the bolts 48 engage with the grooves 39 to pull the side walls 32 against the edge portions and to lock them against the lip formations 18.
  • the bolt 48 is shown not fully screwed in, to assist in showing the ribs 41.

Abstract

Selon l'invention, un système formant clôture comprend une pluralité de poteaux, chaque poteau comportant une lèvre qui s'étend en longueur, une pluralité de panneaux à grille formant clôture, un bord de chaque panneau formant clôture se mettant en contact avec la lèvre du poteau correspondant, et une pluralité d'éléments de rétention allongés, chaque élément de rétention possédant un canal qui, à l'utilisation, met en prise par coulissement la lèvre du poteau correspondant et le bord du panneau formant clôture qui se entre en contact avec ladite lèvre, de manière à retenir le panneau formant clôture contre le poteau. Les éléments de rétention sont verrouillés en place par des boulons soit par ajustement serré. Les panneaux formant clôture possèdent un bord orienté verticalement qui se met en prise avec les extrémités intérieures des lèvres. A l'utilisation, les poteaux sont ancrés dans le sol à des endroits dûment espacés, leurs lèvres étant généralement tournées vers l'extérieur; les panneaux formant clôture sont placés contre les poteaux et les éléments de rétention sont déplacés par coulissement légèrement vers le bas par-dessus les lèvres et les bords associés des panneaux formant clôture. En cas de besoin, on utilise des crampons pour garder en place les bords lorsque les éléments de rétention mettent en prise les poteaux.
