Abstract

The post has a rabbet (11) including two sidewalls (16, 17), where the rabbet receives an end of a panel having a corrugated profile with warped chain edges (21) and weft threads (19). The sidewalls are spaced apart a distance equal to the width of the corrugated profile, where free edges of the sidewalls are not bent. One of the sidewalls includes cut-outs opening laterally towards the outside of the post, where the cut-outs are elongated for receiving an end of some of the weft threads of the panel to allow the introduction of the corrugated profile in the rabbet to lock the panel.

Description

The present invention relates to a fence post comprising a device for assembling this post with a panel, in particular for producing a metal fence. It is more particularly intended to improve and simplify assemblies of the type consisting of welded mesh panels whose edges intended to be assembled to the posts are defined by undulating profile warp son and poles provided on at least one of their lateral faces. a reception channel of the vertices of the corrugated profile.

This type of fence used to materialize a separation between two parcels or to delimit an enclosed space is well known.

This fence is constituted by poles and welded mesh panels, at least the edge warp son have a corrugated profile. The posts are arranged at regular intervals and on these posts are attached the panels removably.

To ensure the attachment of the edge warp son in the channels in the poles, fasteners such as clips, rivet or screws, are implemented.

We still know by the patent application EP 0 903 452 in the name of the present applicant, a fence of this type comprising panels of the welded mesh type with undulating profile warp son, and poles provided on at least one of their lateral faces, a rebate delimited in particular by two side walls placed opposite, one of these walls having a channel.

The Figure 1 shows such a fence of the prior art. The side wall 1 of the rabbet 2 of the post 3, opposite to that comprising a channel 4 has an inclined face 5 to facilitate the insertion of the panel 6 in this channel 4.

This technical solution is particularly advantageous in that it allows a direct assembly of the panel 6 and the corresponding post 3 without added elements.

The mounting of such a fence is thus greatly simplified because the operator does not need to have at his disposal many fasteners. In addition, the time required to construct such a fence is reduced and accordingly, its cost is lower.

However, and although this solution gives very satisfactory results, it can still be improved.

It has indeed been observed that the assembly of this fence is subject to the accuracy of realization of the rigid welded mesh panel which is housed in the rabbet of the post.

Indeed, to ensure the inviolability of this fence, the welded mesh panel must not be removed by lifting the latter.

However, this inviolability is ensured by the jamming of the wire 7 of the fold head, or the top of the corrugation, the panel 6 in the channel 4, or groove. For this, the width of the channel 4 is slightly less than the diameter of the wire 7 of the fold head.

Moreover, during the rotation of the panel for insertion into the rabbet of the post 3, the other face of the panel comes into contact with the flange 1 of the rabbet opposite to that comprising the channel 4. The reaction then exerted on the panel constrains the wire 7 of the fold head to fit forcefully in the channel 4.

As a result, this method of assembly requires the use of a single diameter of wire during the manufacture of the panel. It is therefore necessary to provide for each wire diameter of the panel, a different pole.

In addition, it requires a precise tolerance of the depth of the fold of the panel, which is difficult to obtain in manufacture.

Finally, it also requires a precise tolerance of the profile of the pole, which requires to realize this aluminum pole only.

All these constraints increase the cost of manufacturing such a fence and require in addition either to work with a single and unique diameter warp son, or to have a particular pole for each diameter of warp.

The present invention aims to overcome these various drawbacks by providing a fence post, simple in its design and its operating mode, economic and ensuring a simplified direct assembly of this post with a welded mesh panel.

Another object of the present invention is such a pole accepting different diameters for the constituent warp son of the panels.

Yet another object of the present invention is such a pole requiring lower manufacturing tolerances and thereby allowing the use of other less expensive constituent materials such as steel.

Finally, an object of the present invention is a fence equipped with such posts and welded mesh panels, which is not weakened and whose tamper is improved.

For this purpose, the invention relates to a fence post comprising on at least one of its lateral faces, a rabbet comprising two sidewalls, said rabbet being intended to receive an end of a panel comprising edge profile warp threads. corrugations and weft yarns, said flanks being spaced apart by a distance equal to or substantially equal to the width of said corrugation profile, each of said flanks being devoid of any portion projecting from the rest of this flank towards the inside of the rabbet, at least at the entrance to it.

According to the invention, this post defining a longitudinal axis, one of said flanks of said rabbet has cutouts opening laterally outwardly of the post, said cutouts being elongate to receive and house at least partly the end of at least some said weft yarns of said panel so as to allow the introduction of said corrugation profile into said at least one rabbet for the blocking of this panel.

Once the panels and posts are assembled, the panels can no longer be removed. The extraction from the posts, anchored to the ground, said panels is prohibited by the weft son taken in the notches, or cuts, poles.

Advantageously, these cuts are flared cuts, the narrowest portion of these cuts being placed towards the inside of the post. The introduction of the weft son of the welded mesh panel in these notches is thus facilitated.

Preferably, the narrowest portion is greater than or equal to the smallest diameter of the weft son to be housed at least in part.

The opening providing access to the housing formed by the flanks and the bottom of the rabbet to receive the corrugated profile, therefore extends over the entire distance separating the flanks facing this rabbet. Thus, the flanks placed opposite this rabbet do not have curved free edges such as curved flanges, projecting from the rest of the flanks towards the inside of the rabbet, which would be placed at the entrance of the rabbet. The transverse dimension of the housing is thus not reduced.

Advantageously, the fence post of the present invention has a high mechanical strength while being simpler to manufacture and more compact than the fence posts of the prior art. Its simple geometric shape reduces its manufacturing time and compactness reducing the amount of material needed to obtain it, its manufacturing cost is thus reduced.

Thus, and advantageously, the present fence post is used to receive corrugation panels having corrugations, without modification of these panels, but modification of the structure of the column by the formation of cutouts, or notches, made in the sidewall. rabbet opposite to that intended to receive the peaks of these undulations, and in which the horizontal son, or son of weft, are housed.

The Figures 2 , 3 and 5 show a fence and its fence post according to a preferred embodiment of the invention.

The fence post 10 consists of a section for example of steel or any other material defining on two opposite side faces of the post 10, two rabbets 11 or symmetrical housings, identical and generally rectangular shape, being back to back. The post 10 has front and rear faces 12, 13 curved.

On one side and / or the other, the post 10 can receive the side edge or slice of a panel 14, which then engages in the rabbet 11, or housing, corresponding.

Each rabbet 11 is delimited by a bottom 15 and two flanks 16, 17 which are placed opposite. Each flank 16, 17 has no portion protruding from the rest of the flank 16, 17 towards the inside of the rabbet, particularly at the entrance thereof, so that the space separating said flanks is completely free at this entrance. to allow the introduction of said ripple profile. The free edges of these flanks 16, 17 are therefore not curved but planar. The distance separating these flanks 16, 17 is equal to or substantially equal to the width of said corrugation profile over the entire depth of the rabbet.

The panels 14 are conventional and of the welded mesh type consisting of round metal wires 18 and weft 19, the warp wires 18 having from place to place corrugations 20, only one of which is shown in FIGS. figures 2 and 3 .

The warp 21 of the panel is intended to be engaged in a rabbet 11, the plane of the corrugations 20 of said wire then being perpendicular to the weft threads 19 and parallel or substantially parallel to the flat bottom wall 15. the rabbet 11.

One of the sidewalls 16, 17 of the rabbet 11 is provided with a groove 22 parallel to the longitudinal axis of the post 1, at a short distance from said bottom wall 15 of the rabbet. This groove 22 has a semicircle section equal here to the diameter of the edge warp thread 21.

Since the fence post advantageously makes it possible to work with several diameters of warp threads, the diameter of this groove 22 could be greater than the diameter of the edge warp thread 21.

In accordance with the present invention, this post has on its flank 16 opposite to the side 17 intended to receive the vertices of the corrugations 20, notches 23.

These notches 23 are intended to receive only some of the weft threads 19 of the panel 14, that is to say those which are integral with the straight or substantially straight portions of the edge warp thread 21 placed between the corrugations 20.

When the panel 14 is in the mounted position on the pole 10, as illustrated by the figure 2 , the vertices of the corrugations 8 of the edge warp thread 21 are partially engaged in the groove 22, whereas the straight or substantially linear portions of this edge warp thread 21 placed between its corrugations are substantially in contact with the sidewall. 16 opposite the flank 17 having the groove 22. The weft son integral with these straight portions, or substantially linear, are in turn received in the notches 23.

As shown in Figure 5 the groove 22, or groove, comes to retain the thread of the fold head without jamming it, and some weft son 19 of the panel 14 are housed in the notches 23. Once the panel 14 is trapped between two posts 10 it can not be removed except by destroying it. The inviolability of the fence by lifting the panel is provided precisely by the horizontal weft son engaged in the notches 23.

In addition, any displacement in its plane of the panel 14 for example to extract it from the pole 10 from above is blocked.

On the other hand, the introduction of the panel 14 into the post requires an angle of rotation (r) less than the angle of rotation required to introduce the panel in the groove of a post of the prior art as described by the patent EP 0 903 452 and less accuracy of the depth (p), or width, of the fold of the panel.

The establishment of the panel 14 in the rabbet 11 of the post 10 is illustrated by the Figures 3 and 5 .

The post 10 being anchored in place, the panel is shown as symbolized at 24 ', the vertices of the undulations being placed opposite the groove 22. The ends of the weft threads 19 intended to be introduced into the notches 23 of the opposite sidewall 16 to that having the groove or groove 22, are then gradually introduced into these notches 23 by a rotating action on the panel 14 along the arrow r to force the panel to penetrate completely into the rabbet.

Once the panel 14 in place in the rabbet 11, another pole 10 can be put in place at the other end of this panel.

The two posts being then firmly anchored to the ground, by any appropriate means, the panel 14 can not be extracted.
