[0031] DETAILED STATEMENT OF IMPROVEMENTS

[0032] In the following description, terms relating to a position are taken with reference to a fence system which is in the position of use, that is as shown in Figs. 1 and 2, where Z shows the vertical direction from bottom to top.

[0033] Figures 1 and 2 show the fencing system 100 according to the invention, which comprises a post 102 planted vertically in the ground and which here takes the form of a square-section post, although a different section is possible. Several posts 102 are installed one after the other around the area to be delimited. In the embodiment of the invention presented here, the fencing system 100 also includes a handrail 101 attached to the top of each post 102. Of course, in other embodiments, the handrail 101 may be omitted.

[0034] The post 102 can also be erected on top of a wall directly or by means of a plate attached to the base of the post 102.

[0035] In addition, the fence system 100 can be of different heights depending on the destination of said fence system 100.

[0036] Between two consecutive posts 102, a mesh panel 104a-b is fixed to the two posts 102. The fence system 100 thus comprises, for one post 102, two mesh panels 104a-b.

[0037] Each lattice panel 104a-b is made for example by welding rigid metal wires together with horizontal and vertical wires.

[0038] Each lattice panel 104a-b thus has, at each end, a vertical end bar 106, a top horizontal rail 108a fixed at the top between the vertical end bars 106 and a bottom horizontal rail 108b fixed at the bottom between the vertical end bars 106. Of course, it is possible to have intermediate horizontal rails 108c between the top horizontal rail 108a and the bottom horizontal rail 108b and intermediate vertical bars 107 between the vertical end bars 106.

[0039] As more clearly shown in [Fig. 2], for each horizontal rail 108a-b of each lattice panel 104a-b, the fence system 100 includes a support 110 fixed to the post 102 and on which the horizontal rail 108a-b rests. For each lattice panel 104a-b, there is thus a support 110 for the upper horizontal rail 108a and the lower horizontal rail 108b of said lattice panel 104a-b.

[0040] When there are intermediate horizontal rails 108c, the fence system 100 may include, for at least one of these intermediate horizontal rails 108c, a support 110 fixed to the post 102 and on which the intermediate horizontal rail 108c rests.

[0041] In the embodiment of the invention presented here, the supports 110 for the adjacent lattice panels 104a-b are common and form a single element fixed to the post 102 by a fastening means 103 ([Fig. 4]), here a fixing screw. Thus, the The upper horizontal rails 108a of the two adjacent lattice panels 104a-b rest on the same element forming the two supports 110. Similarly, the lower horizontal rails 108b of the two adjacent lattice panels 104a-b rest on the same element forming the two supports 110. The same arrangement can also be implemented for the intermediate horizontal rails 108c.

[0042] Fig. 4 shows a section at the level of a vertical median plane of the post 102 passing through the fixing screw 103.

[0043] For each support 110 associated with a mesh panel 104a-b, the fence system 100 has a lug 112 which is integral with the support 110 and which is arranged opposite a lug 112 which is also integral with the support 110 and which is associated with the other mesh panel 104a-b.

[0044] Thus, for the upper horizontal rails 108a of the two adjacent lattice panels 104a-b, the fence system 100 has two lugs 112, each being integral with the support 110 corresponding to the lattice panel 104a-b in question, and the two lugs 112 are horizontally opposite each other. The same implementation applies to the lower horizontal rails 108b and the intermediate horizontal rails 108c.

[0045] In the embodiment of the invention presented here, the two supports 110 and the two associated lugs 112 form a single element made of cut and folded sheet metal. Of course, the supports 110 can be made in a different way, for example by molding.

[0046] Between the two opposing lugs 112, a space 109 is provided to receive an end vertical bar 106 of each of the two lattice panels 104a-b and the two end vertical bars 106 are thus arranged between the two lugs 112.

[0047] Each lug 112 has a slope 112a which rises from the support 110 away from the post 102. In other words, the slope 112a descends towards the support 110 while approaching the post 102 to form a sort of clamping wedge.

[0048] The fence system 100 also includes a nut 114 whose axis is vertical, i.e., parallel to the vertical direction Z, and housed in a recess 116 of each support 110 associated with the upper horizontal rail 108a. The nut 114 is removably housed in the recesses 116 to allow the passage of the vertical end bars 106 through the space 109.

[0049] The housings 116 take the form of cutouts in the lugs 112 and the nut 114 is inserted into the housings 116 perpendicular to the vertical direction Z, which ensures a translational locking of the nut 114 parallel to the vertical direction Z.

[0050] The fence system 100 also includes a cover 120, which is best seen in [Fig. 3] and is in the form of a hollow tube oriented vertically parallel to the vertical direction Z. The cover 120 has a wall which is pierced, for each lug 112 associated with a horizontal rail 108a-c, by a slot 122 in which said lug 112. In the embodiment of the invention presented here, each lug 112 takes the form of a flat surface and each slot 122 extends vertically.

[0051] In the embodiment of the invention presented here, the cover 120 also includes, at the slots 122 receiving the lugs 112 associated with the upper horizontal rails 108a, a window 121 passing through the wall of the cover 120 to allow the passage of the nut 114.

[0052] The closure system 100 also includes a shutter 124 fixed at one upper end of the cover 120 and having a bore 124a. The shutter 124 may be an additional element in relation to the cover 120 or a part of the cover 120. Thus, the shutter 124 may be placed on the upper end of the cover 120, inserted into the hollow part of the cover 120, or fixed to the cover by gluing, welding, etc.

[0053] The obturator 124 is above the nut 114.

[0054] The closure system 100 also includes a clamping screw 118 which has a threaded shank 118a and a head 118b. The threaded shank 118a is inserted into the bore 124a of the shutter 124 to be screwed into the nut 114 by passing through the bore 124a and such that the head 118b is in contact with the shutter 124.

[0055] When the nut 114 is in the housings 116 and in the cover 120, it is preferably kept locked in rotation by the adjustments between the nut 114 and the housings and / or by contact with a wall of the cover 120, namely here the wall which is opposite to the wall carrying the slots 122.

[0056] A method for installing such a fence system 100 thus includes an erection step during which the post 102 is erected vertically in the ground or other ground, and then a fixing step during which each support 110 is fixed to the post 102. The fixing step can be carried out prior to driving the post 102 into the ground.

[0057] The installation process continues with a first installation step during which each of the two lattice panels 104a-b is put in place so that the horizontal rails 108a-c (top, bottom and intermediate) rest on the supports 110 and a vertical end bar 106 of each lattice panel 104a-b is arranged between the lugs 112 in the space 109.

[0058] Next, the implantation process continues with a second installation step during which the nut 114 is housed in the housings 116 of the supports 110 associated with the upper horizontal rails 108a, and a third installation step during which the cover 120 is put in place so that each lug 112 fits into a slot 122.

[0059] The implantation process continues with a fourth step in which the shutter 124 is placed at one upper end of the cover 120. The fourth placement step can be carried out beforehand, for example, if The shutter 124 is welded to the cover 120.

[0060] Then during a screwing step, the threaded rod 118a is screwed into the nut 114 by passing through the obturator 124.

[0061] This process is repeated for each post 102.

[0062] During screwing, the cover 120 sinks in following the slope 112a, i.e. going down and getting closer to the post 102. The wall of the cover 120 which has the slots 122 then comes into contact with the horizontal rails 108a-c and pushes them against the post 102, which clamps said horizontal rails 108a-c and therefore the lattice panels 104a-b.

[0063] Fig. 5 shows a section offset from the vertical median plane of the post 102 which shows the interaction between the cover 120, the upper horizontal rail 108a, the slope 112a and the support 110.

[0064] To ensure good contact of the horizontal rails 108a-c against the post 102, the horizontal distance, i.e. perpendicular to the vertical direction Z, between the post 102 and the beginning of the slope 112a is less than the sum of the thickness of the horizontal rail 108a-c and the thickness of the slot 122, i.e. the thickness of the wall of the cover 120 carrying the slots 122.

[0065] To limit the vibrations of the lattice panels 104a-b and the noise that may result from them, in particular at the level of the intermediate horizontal rails 108c for which no support 110 is provided, elastic rings 130 are threaded onto the vertical end bars 106 at the level of at least some of the horizontal rails 108a-c, in particular the intermediate horizontal rails 108c.

[0066] Each elastic ring 130 is split to allow its placement and is made of a flexible material such as silicone or rubber.
