Description

BACKGROUND OF THE INVENTION

Field of the invention

The present invention relates to a flap making it possible to raise a fence element such as a fence post, and to secure a place delimited by a fence.

It also relates to an assembly comprising a fence element and such a flap.

Technological background

The flap is a well-known protective element intended to equip a fence to raise its height and delay the intrusion on sensitive sites (military, airports, ...) or prevent the escape of people (prisons).

These flaps are generally installed in the extension of fence posts, at the upper end of these posts, the latter themselves being planted in the ground to support a solid or hollow panel, for example of the mesh type, and form a fence. .

These flaps can be arranged in a straight or inclined manner, towards the inside or towards the outside of the fence, for example by forming an angle greater than 45 ° with the corresponding post.

Between two adjacent flaps are placed protective devices such as rows of brambles, ribbons of barbed wire or defensive systems intended to dissuade the crossing of the fence.

By way of illustration, these flaps take the form of bent pieces produced by the assembly by welding of a first profile intended to be force-fitted through its base into the upper part of a post, and of a second profile intended to support protective devices.

Fasteners such as metal wires or collars, are typically attached to ensure the attachment of the protective devices on these flaps.

It follows logistical considerations for the management of these fasteners and a painful work of installation for the operators.

We also observe that these flaps are particularly heavy and bulky for their transport and storage.

In addition, these flaps generally have a shape related to that of the fence post on which they are intended to be introduced by force. These flaps are thus designed for specific fence posts and they cannot generally be adapted on other posts. They are thus not versatile.

In addition, the cost of manufacturing these flaps and the ecological impact of their production are significant.

There is therefore a pressing need for a flap whose original design overcomes the various drawbacks of the prior art mentioned above.

Object of the invention

The present invention relates to a flap for a fence element, simple in its design and in its operating mode, versatile, economical and allowing the attachment of a protection device without any attached fastener.

Another object of the present invention is such a flap whose weight is reduced significantly while remaining robust, and whose size is minimized to facilitate its storage and transport.

Another object of this invention is such a flap whose need for material is reduced and the ecological impact of its manufacture is limited.

The present invention also relates to a fence element such as a fence post or a movable fence gate, equipped with such a flap. BRIEF DESCRIPTION OF THE INVENTION

To this end, the invention relates to a flap for a fence element comprising an assembly part for a fence element and an anti-crossing part, said anti-crossing part being intended to support at least one protective wire or tape.

According to the invention,

said anti-crossing portion comprises an elongated wing for receiving said at least one protective wire or tape, said elongated wing comprising a lateral edge and comprising at least one L-shaped cutout opening out onto said lateral edge for the passage of a wire or protective tape, and

- Said L-shaped cutout forming a housing in the thickness of said elongated wing defining a foldable tongue for trapping said protective wire or tape in this housing so as to assemble said protective wire or tape to said anti-crossing part.

The large branch of this L-shaped cutout thus delimits with the lateral edge of the elongated wing which is thus cut out, a foldable tongue. This tab is foldable for before folding, allow the introduction or engagement of a protective wire or ribbon in the housing defined by said cut in L and after folding, enclose this wire or ribbon in this housing, fixing the latter on the flap.

Advantageously, before folding down, this tongue which forms an integral part of the free lateral edge of the elongated wing, determines part of the edge of this elongated wing and is therefore level, or substantially level with this edge of the wing. lying down.

With the flap of the invention, the user no longer needs to use, when installing a protective wire or tape, fasteners for securing this protective wire or tape on the flap , but only has to fold, or fold down, each corresponding tab to trap the latter in the corresponding housings. The assembly operations of the protective elements are therefore particularly simplified.

The leverage when folding each tab can be all the more important as the large branch of the L-shaped cut is long, making it easier to fold the tab. In addition, or alternatively, this folding can be facilitated by the presence of a structural weakness at the base of the tongue obtained by removal of material.

Preferably, the protective wire or tape is a barbed wire also called a bramble, or a barbed tape in which can optionally be placed a current transport cable and / or a feed cable, or a tension wire intended for serve as support and allow the deployment and assembly of a defensive system.

Different particular embodiments of this flap are conceivable, each having its particular advantages and susceptible of numerous possible technical combinations:

this flap is made in one piece, or in one piece. It is thus reahsed in a single material such as metal, preferably steel, and even better of galvanized and plasticized or powder coated steel.

For purely illustrative purposes, this flap is reheated from a cut and shaped sheet metal or phée.

Having no weld, this advantageously strengthens the mechanical structure of this flap.

this flap is straight, angled or Y-shaped.

Preferably, when the latter is bent, the anti-crossing part forms an angle greater than 45 ° with the corresponding assembly part.

the anti-crossing part and said assembly part each define an angle iron, one wing of which is common to said two parts.

Advantageously, the assembly part comprises two wings connected by a folding hgne, this assembly part comprising one or more holes for the passage of the rod of a fixing placed on at least one of said wings. Preferably, this attachment comprises a screw and a self-breaking nut.

Alternatively, this assembly part may not form an angle and have a shape intended to cooperate with the shape of the upper part of the post on which the flap is intended to be placed.

each L-shaped cutout determining a large branch and a small branch, said small branch opens onto the lateral edge of the elongated wing of said anti-crossing part for the introduction of a protective wire or tape, said foldable tongue comprises a zone of least mechanical resistance, preferably at its base, in order to facilitate and orient its folding towards the interior of the housing defined by said L-shaped cutout.

The folding of the tab to trap a wire or protective tape in its housing after introduction is thus made particularly easy and quick.

Preferably, a portion of said large branch is wider than the rest of said cut to create this zone of less mechanical resistance.

Advantageously, this large branch has a recess of circular shape, preferably placed at its end connecting it to the rest of the elongated wing, that is to say at the base of the tongue, to facilitate the folding of that -this. Could this recess take any other form?

said anti-crossing part comprises at least two L-shaped cutouts to receive at least two rows of defensive wire or tape. Preferably, it includes at least 3 L-shaped cutouts.

The present invention also relates to a fence element and a flap as described above.

This set may be in the form of separate elements and therefore form an integral part of a kit or may be in the form of assembled elements.

Advantageously, this fence element is a fence post or a movable fence panel.

The present invention also relates to a fence comprising at least one flap as described above.

The present invention also relates to an element for raising and anti-crossing a wall comprising at least one flap as described above.

Advantageously, this or these flaps can be assembled on said wall by any fixing means. For example, they are installed on the wall.

BRIEF DESCRIPTION OF THE DRAWINGS

Other advantages, aims and particular characteristics of the present invention will emerge from the description which follows, made, for explanatory purposes and in no way limitative, with reference to the appended drawings, in which:

- Figure 1 schematically shows a front view of a flap according to a particular embodiment of the invention;

- Figure 2 is an enlarged and partial view of the anti-franking part of the flap of FIG. 1 showing the free end thereof;

- Figure 3 is a partial perspective view of the flap of FIG. 1;

DETAILED DESCRIPTION OF THE EMBODIMENT OF THE INVENTION First of all, it is noted that the figures are not to scale.

Figures 1 to 3 show schematically a flap 10 for a fence element such as a post, according to a particular embodiment of the present invention.

This flap 10 comprises an assembly part 11 to this fence element and an anti-crossing part 12, which is intended to support several rows of briar, also called a barbed wire.

These assembly and anti-crossing parts each define an angle here, a wing 13 of which is common to the two parts, the flap 10 being in one piece and produced by cutting a sheet and folding it.

The assembly part 11 to the fence element thus has two support wings each provided with holes 14 for the passage of the fastening rod making it possible to secure the base of the flap 10 to the fence element.

The anti-crossing part 12 forms an angle of 45 ° with this joining part 11. Advantageously, depending on the face of the post retained for mounting the joining part 11, this anti-crossing part 12 can be inclined towards the inside or outside the fence.

The anti-crossing part 12 comprises an elongated wing 15 for receiving several barbed wires, this elongated wing 15 comprising a free lateral edge and for each barbed wire to be supported, an L-shaped cutout 16 opening onto this lateral edge for the introduction and the passage of the corresponding barbed wire.

Each L-shaped cutout 16 thus forms a housing in the thickness of the elongated wing 15 of the anti-crossing portion 12 by delimiting in the elongated wing 15 a foldable tongue 17 to trap this barbed wire in this housing so as to '' assemble to this anti-crossing part 12.

As shown in particular in FIG. 2, each L-shaped cutout 16 determining a large branch and a small branch, the small branch opens onto the lateral edge of the elongated wing 15 of the anti-crossing section 12 for the introduction of a wire or protective tape. The end of the large branch is wider than the rest of the cut to create a zone 18 of less mechanical resistance at the base of the tongue 17 in order to facilitate and orient its folding towards the interior of the housing defined by said cut in L.

Such a flap 10 is of less weight compared to the flaps 10 of the state of the art and is therefore easier to handle. It advantageously makes it possible to support, in addition, loads which can reach several tens of kilograms, here, 80 Kgs. It also offers more installation possibilities.
