Title of the invention: FENCE SYSTEM Technical field

[0001] The present invention relates to a fencing system which comprises a trellis and a cover ensuring the locking of the trellis, as well as a method of installing such a fencing system. STATE OF THE PRIOR ART

[0002] A state-of-the-art fencing system typically comprises posts which are driven into the ground one after the other and lattice panels, each end of which is fixed to a post by fixing means.

[0003] Various means of fixing are known, but none give complete satisfaction. Statement of the invention

[0007] - two lattice panels, each having a vertical end bar at each end, a high horizontal rail fixed at the top between the vertical end bars and a low horizontal rail fixed at the bottom between the vertical end bars,

[0008] - for each horizontal rail of each lattice panel, a support fixed to the post and on which the horizontal rail rests,

[0009] - for each support associated with a lattice panel, a lug secured to the support and arranged opposite a lug secured to the support associated with the other lattice panel, where a vertical end bar of each lattice panel is arranged between the two lugs, where each lug has a slope which rises from the support away from the post,

[0010] - a nut with a vertical axis and housed in a housing of each support associated with the rail high horizontal,

[0031] DETAILED DESCRIPTION OF EMBODIMENTS

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

[0033] [Fig.l] and [Fig.2] show the fencing system 100 according to the invention which comprises a post 102 which is planted vertically in the ground and which here takes the form of a square-section post, but a different section is conceivable. Of course, several posts 102 are installed one after the other around the land to be delimited. In the embodiment of the invention presented here, the fencing system 100 also comprises a handrail 101 which is fixed to the top of each post 102. Of course, in other embodiments, the handrail 101 may be absent.

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

[0035] Furthermore, the fencing system 100 may be of different heights depending on the purpose of said fencing system 100.

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

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

[0038] Each lattice panel 104a-b thus has a vertical end bar 106 at each end, a top horizontal rail 108a fixed in the upper part between the vertical end bars 106 and a bottom horizontal rail 108b fixed in the lower part 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 shown more clearly in [Fig.2], for each horizontal rail 108a-b of each lattice panel 104a-b, the fencing system 100 comprises 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 fencing system 100 may comprise, 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 neighboring lattice panels 104a-b are common and form a single element fixed to the post 102 by a fixing means 103 ([Fig.4]), here a fixing screw. Thus, the upper horizontal rails 108a of the two neighboring lattice panels 104a-b rest on the same element forming the two supports 110. In the same way, the lower horizontal rails 108b of the two neighboring lattice panels 104a-b rest on the same element forming the two supports 110. The same layout can also be implemented for the intermediate horizontal rails 108c.

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

[0043] For each support 110 associated with a lattice panel 104a-b, the fencing 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 lattice panel 104a-b.

[0044] Thus, for the upper horizontal rails 108a of the two neighboring lattice panels 104a-b, the fencing system 100 has two lugs 112, each being integral with the support 110 corresponding to the lattice panel 104a-b concerned, and the two lugs 112 are horizontally opposite each other. The same implementation applies for 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 produced in a different manner, for example by molding.

[0046] Between the two facing lugs 112, a space 109 is provided to receive a vertical end bar 106 of each of the two lattice panels 104a-b and the two vertical end 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 fencing system 100 also comprises a nut 114 whose axis is vertical, that is to say parallel to the vertical direction Z, and housed in a housing 116 of each support 110 associated with the upper horizontal rail 108a. The nut 114 is removably housed in the housings 116 to allow the passage of the end vertical bars 106 in the space 109.

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

[0050] The fencing system 100 also comprises a cover 120 which is best seen in [Fig.3] and which 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, with a slot 122 in which said lug 112. In the embodiment of the invention presented here, each lug 112 takes the form of a planar surface and each slot 122 extends vertically.

[0051] In the embodiment of the invention presented here, the cover 120 also comprises, at the level of 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 comprises a shutter 124 fixed at an upper end of the cover 120 and having a bore 124a. The shutter 124 may be an additional element relative 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, pressed into the hollow part of the cover 120, or fixed to the cover by gluing, welding, etc.

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

[0054] The closure system 100 also comprises a clamping screw 118 which has a threaded rod 118a and a head 118b. The threaded rod 118a is introduced into the bore 124a of the shutter 124 to be screwed into the nut 114 by passing through the bore 124a and so that the head 118b bears against 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 the wall carrying the slots 122.

[0056] A method of installing such a fencing system 100 thus comprises a raising step during which the post 102 is raised vertically in the ground or elsewhere, 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.

[0057] The implantation method continues with a first installation step during which each of the two lattice panels 104a-b is installed so that the horizontal rails 108a-c (high, low 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] Then, the implantation method 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 is housed in a slot 122.

[0059] The implantation method continues with a fourth step during which the shutter 124 is put in place at an upper end of the cover 120. The fourth installation 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 passing through the shutter 124.

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

[0062] During screwing, the cover 120 sinks following the slope 112a, that is to say descending and approaching the post 102. The wall of the cover 120 which carries 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 application 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 start 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 pollution which may result therefrom, 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 end vertical 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 it to be put in place and is made of a flexible material such as silicone or rubber.
