Description

Fence comprising at least one post and at least one ribbed panel The invention relates to the technical field of metal fences composed of panels attached to posts. The invention relates more particularly to metal fences comprising wire mesh panels. Typically, these wire mesh panels are hung on the posts during the laying of the fence.

An advantage of this fence is that when the fence is laid, the removal of malicious signs is more difficult.

In the present text, the words "lattice panels" refer to woven or welded wire panels, metallic or not, with or without a decorative and / or protective coating, said coating being metallic or of polymeric material.

Conventionally, these lattice panels are composed of square or rectangular meshes and comprise, at first, parallel son which, when using the panels, are essentially installed in a vertical position. These first threads are indicated in this text by the words "longitudinal threads".

In a second stage, the lattice panels comprise parallel wires which, when using the panels, are essentially installed in a horizontal position. These yarns are indicated in the present text with the words "transverse yarns." In the prior art, several principles of fastening lattice panels to columns are described.

Canadian patent application CA2059777 discloses a fence comprising posts for securing ribbed panels between posts. This type of panel comprises a first flat portion and a second rib portion having at least one rib for increasing the rigidity of the panel.

The posts according to Canadian Patent Application CA2059777 are provided with hooks being dimensioned to ensure that the different hooks can hang the end of the panel, that is to say the longitudinal son at the ends of the panel, on the flat part said panel. In addition, the hooks are sized to allow the hooks to enter the interior of the rib and this to prevent the branches constituting said rib does not hit the hooks, thus making possible a proper attachment of the panel on the pole.

One of the disadvantages of the solution disclosed by Canadian Patent Application CA2059777 is that the length of the hook is essentially determined by the length of the rib.

In practice, by placing a fence on sloping ground, adjacent poles may not be positioned at the same height.

The underlying panels are moved to a vertical position to compensate for the slope of the terrain. By moving a panel relative to the adjacent panel, the minimum vertical displacement pitch for the panel is at least equal to the length of a hook.

In other words, in the solution proposed in the prior art, the minimum differences in height between two adjacent panels are at least a length of a hook determined by the relatively large length of the rib.

The object of the present invention is to provide a fence comprising at least one post and a panel for attachment to the post in which the minimum distance over which the board can be moved in the vertical position on said post is no longer determined by the length of the rib.

The object of the invention is a fence comprising at least one lattice panel and at least one pole for fixing said panel, wherein said lattice panel is formed of longitudinal and transverse wires, said panel being provided with at least one flat portion and at least one ribbed portion, said ribbed portion comprising at least one rib, said ridge comprising two branches, the first leg extending from a first transverse wire via a first bending zone to a second transverse wire, and the second leg extending from said second transverse wire via a second bending zone to a third transverse wire, said post comprising hook type hooking means for hooking the longitudinal wires at the ends of the panel, said hooks are separated by openings adapted to receive the ends of the transverse son of the panel, wherein each hook comprises a first and a second tab, located on the free edge of said means and spaced by a distance sufficient to allow the passage of one of the branches of said rib, wherein the hooks are sized to hang the panel on the pole between the first transverse wire and the first zone of curvature of the rib by a first tongue of a first hook, and between the end of the second bend zone and the third transverse wire by a second tongue of a second hook.

The technical result of these measurements lies in the fact that the panel can be fixed in a first position to the post. In the case where the user wishes to move the panel in a vertical position along the pole, this displacement can be carried out over a distance which is no longer determined by the length of the rib but which is determined solely by the length of the rib. a hook, said hook being, according to the present invention, not determined by the length of said rib.

In practice, this means that two panels can be attached to the pole, in a vertical position, with a minimum distance.

According to a preferred embodiment, the hooks are sized to hang the panel on the post between the first transverse wire and the beginning of the curvature zone of the rib by a first tab of a first hook, and between the end of the second bending zone and the third transverse wire by a second tongue of a second hook adjacent to the first hook.

According to a preferred embodiment, the rib has essentially the shape of a V.

In a second step, the invention also relates to a post, adapted for the fence according to the invention, wherein the post comprises hook type hooking means for hooking the longitudinal son at the ends of a lattice panel being formed of longitudinal and transverse yarns, said panel being provided with at least one flat part and at least one ribbed part, said ribbed part comprising at least one rib, said rib comprising two branches and in which said attachment means are separated by openings adapted to receive the ends of the transverse son of said panel, each attachment means comprising a first and a second tongue, located on the free edge of said means and spaced by a sufficient distance to allow the passage of one of the branches of said rib.

The invention will be better understood and the advantages better appreciated on reading the description which follows and with reference to the following figures, in which: FIG. 1 shows the detail of a fence according to the present invention, FIG. according to Figure 1 in "front view" view, Figure 3 shows the pole according to the invention, in section, and - Figure 4 shows the fence according to the invention in "side" view.

In Figure 1, the fence 1 according to the invention is shown. The fence includes a pole 10 on which a first 20 and a second panel 20 are hung. The profile of the post 10 is shown "in section" in FIG. 3. The post comprises a first element 11, essentially in the form of a flattened tube, a central part 12 directly connected to the part 11 and the part allowing to to hang the panels comprising a first element 13 and a second element 14, essentially in the form of a "J". As clearly indicated in FIG. 3, the post 10 is obtained by folding a flat metal element into its final form. To ensure this shape, the two walls forming the central element 12 are connected to the zone 15. The parts 13 and 14 each have a free edge, respectively 16 and 17. These free edges 16 and 17 are adapted to hang a panel on the post 10, as shown in Figure 1.

Continuing with Fig. 1, the post 10 is provided with a cap 18 for protecting the upper end of the post. The panel 20 comprises at first longitudinal son 21. These son are substantially parallel. The various wires 21 are connected by transverse wires 22. The panel 20 is also shown in FIG. 2 where it is clearly indicated that this panel 20 has a flat portion 23 having at each end a ribbed portion 24. It is necessary to understand that the embodiment of the panel 20 according to Figure 2 is merely an example. In the case where the panel is longer, it is possible to have, for example, a first rib, a second rib and a third rib at both ends and in the middle of the panel. Other embodiments of the panel are also possible.

The connection of the ribbed portion 24 to the post is clearly indicated in FIG. 1. This ribbed portion begins with a first connection between a longitudinal wire 21 and a transverse wire 22 '. The beginning of the rib is indicated using the reference letter A. From this connection A, the rib extends, at first, towards a zone of curvature B. This means that the rib begins at a distance from the transverse wire 22 '. From the first curvature B, the rib continues forming a first branch 25 to a second connection point between the longitudinal wire 21 and a second transverse wire 22. This connection point is indicated by means of the letter of reference C. From this connection point C, the rib continues forming a second branch 26 in the direction of a second zone of curvature D. From this second curvature zone D, the rib continues towards a third point of contact between the longitudinal wire 21 and the transverse wire 22 ". This third point of contact is indicated by reference letter E.

There are several possibilities for hanging the panel 20 around the ribbed portion 24. A first possibility is to ensure that all the hooks present at the post 10 each have a length less than the distance between the points B and D in the direction of the wire 21. In this case, it is ensured that the hook can enter the curved portion of the panel without preventing the connection of the panel 20 with the pole 10.

A disadvantage of this solution lies in the fact that the panel is not correctly hooked around the connection A or around the connection E between the longitudinal wires 21 and the transverse wires 22.

A second possibility is to ensure that all the hooks on the post 10 each have a length less than the distance between the points A and E in the direction of the wire 21.

With such a solution, it is possible to hang the panel 20 correctly, but in this case the length of the hooks is determined by the shape and the length of the rib 24.

According to the invention, the post 10 is provided with hooks 30 formed at the end of the parts 13 and 14, as shown in Figure 3. The hooks 30 are separated by notches 33 adapted to receive the ends of the transverse son 22 Each hook 30 is, at its free edge, provided with two tongues 31 and 32. Between the tongues 31 and 32, a certain distance is respected in order to allow the passage of the branches 25 and 26 of the rib 24.

In practice, the panel 20 can be hooked to the post 10 by means of a first tongue 31 of a first hook 30 in the space existing between the fixing point A, between the longitudinal wire 21 and the transverse wire 22, and the zone at the same time, a second tongue 32 of a second hook 30 is placed between the second zone of curvature D and the point of attachment A, between the longitudinal wire 21 and the transverse wire 22.

As indicated in FIG. 1, the branches 25 and 26 of the rib 24 can pass between the first tongue 31 and the second tongue 32 of the hooks 30. In the embodiment according to FIG. 1, two hooks 30 are present between the transverse wires. 32 forming the rib 24. It should be understood that three or more hooks can also be used.

As clearly indicated in FIG. 1, the major advantage of the fence 1 according to the present invention lies in the fact that the user can, if necessary, move the panel with respect to the pole over a length corresponding to the length of the fence. one hook. In other words, the distance, on which the panel can be moved, is minimal. In addition, this distance is no longer determined by the length of the rib. In practice, the distance between point A and point E, as indicated in FIG. 1, lies in a range of between 10 and 15 cm. This means that the minimum distance over which the panel can be moved is of the order of 4 to 8 cm.

As indicated above in FIG. 2, the fence 1 according to the invention is shown in "rear face" view. In the middle, the pole 10 is shown and on each side a panel 20 is hooked. Figure 2 clearly shows the ribbed portions 24 as well as the flat portion 23 of the panel 20. Figure 3 is described in detail above.

FIG. 4 shows the connection of the post 10 on the panel 20 and clearly shows that a first tab 31 is present between the connection A and the bending zone B (see FIG. 1) and, at the same time, a second tab 32 a second hook is present between the second curvature zone D and the connection E (see FIG. 1).

This means that the panel 20 is correctly hooked to the post 10 on the flat part 23 (see Figure 2) but also around the point A and the point E. This attachment around the point A and the point E (see Figure 1) is essential to properly secure the panel to the post.

In this text, reference is made to the attachment of a ribbed panel on the pole. It should be understood that the post can be used in combination with a flat panel. 10
