Description

The present invention relates to a cl 8 ture intended in particular, but

not limited to surrounding

sports fields.

  Fences around sports fields or stadiums usually consist of vertical poles and horizontal poles resting on the poles at their ends. In order to allow the passage of ground or stadium maintenance machines, such as lawn mowers for example, this fence must necessarily have interruptions that are frequently closed by removable chains We are therefore obliged to unlock and re-lock these chains at each field maintenance operation, or not to provide any channels at all

  leaving therefore the opening of passage consta-

free.

  The present invention aims to overcome these disadvantages by providing a fence that can be easily opened and closed to let the maintenance equipment, and without requiring any element

Annex.

  According to the invention, the clnture comprises, at the top of each post, a projecting piece integral with

  this one, and the ends of the adjoining

  on this post have corresponding recesses

  to the configuration of the projecting piece so that said ends can come to fit on the protruding part, which thus ensures the maintenance of the smooth on the pole. The posts and the rails may be of concrete and are held in place by gravity, the protruding part being made of metal (protected against corrosion) or of a suitable plastic material such as extruded polyvinyl chloride, polypropylene, etc., sealed in the

  top of the post by embedding in the concrete.

  Preferably, an expansion joint is reserved between the end faces opposite the adjacent rails, the recesses thereof being dimensioned for this purpose according to the dimensions of the protruding part. Thus for concrete rails of about two meters in length and weighing 60 kg, it is possible to provide a joint of about 0.5 cm, allowing the rails to expand freely.

and without disorder.

  Under these conditions, each rail can be easily removed by simply lifting to release the protruding parts that hold these ends, and this at any point of the fence the structure provided by the invention therefore has great flexibility since it allows to easily open a passage in any place of the fence, and to close it again just as easily by replacing the rail on the two pieces of restraint.

  Other peculiarities and advantages of

visible in Figure 6.

  The cross section shown in FIG. 1 comprises two vertical posts 1 at the top of each of which bear the ends opposite two adjacent rails 2, 3 and 3, 4 The posts 1 and the rails 2, 3, 4 are for example made of concrete, the slats having a hexagonal section, such cl 8 ture being used in particular to achieve the entourage of sports fields

and stages.

  To ensure the maintenance of the rails 2, 3, 4 on the posts 1, the invention provides, at the top

  of each post 1, a protruding part 5 integral with that

  ci (Figures 2 to 4) The ends of the adjoining smooth 2, 3 and 3, 4, which rest on this pole 1 each have a recess 6 corresponding to the configuration of the part 5, so that said ends will stick; vezir nest on the piece 5 which ensures the maintenance of

  smooth 2, 3, 4 on the corresponding post 1.

  In the embodiment illustrated in FIGS. 2 to 5, the projecting piece 5 has an H section and is sealed or embedded in the upper part of the post 1.

  in Figure 3 that this piece may have varying heights

  The piece 5 shown in continuous lines having the minimum height, while the part 5 has been shown in broken lines at a much greater height. This part can be embedded in the concrete of the post 1, the part which can be inset recessed. on the height shown in broken lines, and projecting above the top

  of the post 1 by its part shown in full line.

  Each end of the rails 2, 3 and 3, 4 is hollowed out so as to have a housing 6 having a T-section substantially corresponding to half the H-section of the piece 5, which allows to embed the end the smooth on the piece 5; the two ends opposite the adjoining rails have complementary housing 6 to fit on the part 5 in H. A seal 7 (Figure 1) of expansion is reserved between the end faces vis-à-vis adjoining rails 2, 3 and 3, 4 etc., the housings 6 of which are dimensioned for this purpose. As a numerical example, for concrete rails with a length of two meters and a weight of kg, the joint 7 can have a width of 0.5 cm as

indicated above.

  In the embodiment shown in FIGS. 6 and 7, the right-angle connection of two rails 8, 9

  at an angle of closure is first ensured by

  parallel to each other the end faces

  11, 12 of the rails 8, 9, at 45 degrees on the axes of these

  ci Complementarily, the support pole 13 of the smooth 8, 9 is provided at its top with a protruding piece 14 having in this example a section substantially S, or more

  precisely in the form of two L connected by their ends.

  The part 14 thus consists of two parallel vertical wings 14a and a transverse connecting branch 14b ndicular wings 14a It can have a variable height as the protruding part 5, and be embedded in the LJ-tone of the post 13 on a height h equal to the height of

  part of the piece 14 c shown in broken lines.

  ) Complementarily, the biased ends of the corresponding lissers 8, 9 have housings 15 of identical shape T, allowing said ends U to be engaged: the part 14 The housings 15 are dimensioned so as to be able to fit between the end faces 11, 12

anointed with dilation of width d.

  The wing 14 has recessed into the smoothing beam 9

  culairement to the axis thereof, opposes the withdrawal of this smooth by traction parallel to its axis and thus maintains the smooth 9 in place in this direction, while I rz intermediate branch 14 b maintains the smooth 9 in the

  perpendicular connection, and the same for the rail 8.

  As in the previous embodiment, the smooth-t 9 can be easily installed and removed and easily to open a passage at the closing angle. It is possible to seal the

  smooth on the poles by sinking into the expansion joints

  A liquid mortar may also be left on the inner side of the stringers to secure the tensioning wires of a mesh, which presents

  particular interest for stadiums.

  The invention is not limited to the forms of

  described and may include variants of

  p.ion Thus it is obvious that one can give to the retaining parts set up at the top of the posts sections different from those illustrated by way of examples, the lodgings formed in the end portions of the rails

There are corresponding sections.

  In the case where it is desired to secure the beam with the post, this securing can be performed, either with a horizontal key through the soul of

  part 5, either by having the beam pass through the recess

  6, and casting a mortar after installation

of the smooth.

  The fence according to the invention is usable for various applications, not only for sports fields and stadiums, but also for racetracks.

  or to close land intended for other uses.
