Abstract

The fence post (1), designed to be fitted with mesh panels (2) made from horizontal (3) and vertical (4) rods with local horizontal ribs (5), has edges that are curled over to receive vertical end rods (8) on the panels. The curled edges are divided into sections by slots at intervals corresponding to the distance between horizontal panel rods and have additional slots for the ribs (5). The rods (8) are fitted into the curled edges with the aid of a special tool with hooked ends.

Description

Enclosure.

The invention relates to an enclosure.

To materialize a separation between two plots or delimit a closed space, it is known to raise a enclosure in the separation line.

This enclosure consists of posts and panels.

The posts are arranged at intervals regular and these panels are detachably fixed panels, especially welded reticulated panels.

To keep these panels on these posts, it They know different assemblies.

A first assembly (see document FR-A-2,697,565) is to hold the vertical wire located at the end of the panel by means of a flange held in position by a bolt that crosses the bottom of the groove in which the vertical edge of the panel is located.

This solution offers resistance important.

Another mode of assembly is known (see EP-0.478.454) which consists of replacing the flange held by a bolt, by a clip that hooks elastically in highlights that the profile presents.

This solution offers worse resistance, but allows to fix the fixing means more quickly.

These two solutions thus turn to poles, more or less rigid cross-linked panels and fixing means complementary, namely a flange or a clip.

Thus, the provisioning of the works of placement should be followed meticulously to prevent the fixing means are insufficient

Another mode of assembly is known (see documents FR-A-2,676,488, FR-A-2.316.414, EP-1 098 051) that does not need additional fixing means.

To this end, the post presents along its longitudinal axis, a multitude of hooks regularly spaced to which hooks the panel.

These hooks are relatively wide sheets so that they limit the displacement of the panel with respect to the longitudinal axis of the post.

For manufacturing, the pole is manufactured generally in folded or extruded metal and, locally, are provided notches whose passage corresponds to the passage of horizontal wires of the hooked cross-linked panel above.

The width of these notches is therefore of the order of the diameter of the horizontal wires and the distance between two notches corresponds to the passage of the wires horizontal or to a multiple or submultiple.

The width of the hooks is therefore slightly less than the distance between two horizontal wires successive or a submultiple.

Sometimes, at the tip of the pole, the hook it is much less wide than the others, but this results from the post length choice.

For example, the distance between two wires horizontal corresponds to twice the width of a sheet increased in the width of the notch that separates these two sheets.

The strength of the enclosure depends on the anchoring of the posts, of the connection means used between the post and the panel, and the peculiarities of the panel.

To improve the panels and especially limit their flexion when these are subjected to a force perpendicular to the panel plane, these are folded locally to constitute a nerve or several horizontal nerves.

These are obtained by folding or deformation of Vertical wires

With the flange or clip type assembly mode, These nerves are not annoying.

Unfortunately, this is not the case with a hook type assembly.

Indeed, at the level of the nerve, the wire terminal is deflected and cannot be inserted into the hook correspondent.

The solution currently retained consists of suppress locally and in sectioning this terminal wire level of the fold.

This solution weakens the panel and, therefore, therefore, the enclosure, since there is no continuity of the wires  horizontal of the nerve with the terminal wire.

The invention is particularly intended to provide A solution to the problems mentioned above.

For this purpose, the invention aims at a enclosure according to the features of the claim principal.

The invention will be well understood with the help of the description that follows as a non-limiting example, referring to the attached drawings, which represent schematically:

- Figure 1: a pole according to the prior art

- Figures 2 to 5: a pole according to the invention

- Figure 6: an enclosure according to the invention

- Figures 7 to 10: assembly kinematics from a panel to a pole by means of a positioning key

- Figure 11: a vertical sectional view of a panel assembled to a pole.

Referring to the drawings, you see a post 1 to constitute an enclosure.

To this post 1, a panel 2 is hooked reticulate formed by horizontal wires 3 and vertical 4 in Particularly distributed regularly, presenting this panel locally 5 horizontal nerves to improve their resistance to flexion.

These nerves usually have a section in V.

In the exemplary embodiment shown, this post presents a symmetry so that, to the mentioned post, you can hook two panels.

Post 1 has a global form of H.

This one, therefore, presents a 1A soul that it comprises, on one side, a plate 1B and, on the other, two series 1C of 6 flattened hooks.

Plate 1B may be combated or replaced by a tubular part.

So, this post has two slots A, B opposite.

Each post, according to the prior art (see figure 1) includes along its axis, regularly distributed, 6 curved sheets to form, each, a hook, the hooks being spaced apart from each other according to a multiple step or submultiple of the passage of the horizontal wires of the panel that should hooked on him.

Thus, each hook 6 is formed by two lips 6A, 6B joined by a rounding 6C.

These two lips 6A, 6B form a V that allows receive wires 8 panel terminals that have a section different.

One 6A of the lips is associated at least indirectly to the soul of the pole and the other 6B to a free edge 6D to be inserted through the panel mesh and retain the wire vertical terminal 8.

According to the prior art, the width of each sheet 6 is approximately equal to the distance between two consecutive horizontal panel wires or a multiple or a submultiple of this distance.

The distance between the sheets is of the order of one to three times the diameter of the horizontal wire so that This sizing ensures a block in vertical translation of the panel.

According to the invention, at least some of the curved sheets have, at least locally, a width "l" at least equal to the width "L" of the rib 5 of the panel intended to catch on the pole.

The width "L" of the nerve is the distance taken at the level of the location of the hook blade after of the pole / panel assembly.

This is defined between the points of intersection of the inclined branches 10, 11 of the nerve and of a straight 12 which, parallel to the terminal wire 8, is removed from this terminal wire a value at least equal to the thickness of the sheet 6.

A width "l" of the sheet 6 less than This distance "X" facilitates the placement of the hook.

This avoids sectioning the terminal wire level of the nerve This appears clearly in Figure 6 in which it is seen that the nerve is not cut

Thus, this allows to suppress the panel weakening and therefore get a very close resistant. This reduction in hook width can be applied in the place where the nerve is placed, but, for convenience, this reduction can be done on all hooks.

In one embodiment, it is the entire hook the one with a reduced width.

In a second embodiment (see the Figures 2, 3, 4), the reduced width of the sheet is located exclusively on that (6B) of the two lips 6A, 6B that form the hook presenting the free edge of said hook.

According to this last embodiment (see Figure 2), preferably, but not necessarily, the intersection between the lip of reduced width and the remaining part of the hook not reduced width has a supplementary rounded cutout 13 to allow the angular orientation of the panel beyond the angle straight formed between the bottom of the groove and the panel.

Figures 2 to 5 show different posts of according to the invention.

Figures 2 to 4 show that all hooks have a reduced width located only at the level of the lip which carries the free edge of the hook.

Figure 5 shows hooks whose width is reduced in almost all the hooks of the post and, for the fixation in translation, it is expected that certain notches "Z" separating two hooks remain, however, of restricted dimension.

For the provisional maintenance of the panel in The post uses a tool 20 for placement.

This tool or placement wrench is presents in the form of a piece 20 that, by rotation, rests between the bottom of the post groove and the terminal wire.

Figures 7 to 10 show the key in several positions. This key comes in the form of a piece that has A hook shape.

This piece is inserted from the slot.

It has a straight-guided guide face 21 which rests on the bottom of the groove.

The guiding face is joined by a curve 22, to face 23 of maintenance in position which, relying on the soul of the pole, block the wire, leaning the front part 24 of the hook on the terminal wire.

This rests on the bottom of the groove for be positioned so that it performs a blockade by reaction of the wire on the bottom of the slot through the key.

The concave part of the hook allows free of lip 6b bearing the free edge.
