Description

The present invention relates to the technical field of fences, including the field of fences consisting of an alternation of poles and grillage panels.

In the state of the art, it is known that the fastening of the grilling panels is carried out by screwed fasteners or else by grooves comprising notches.

A disadvantage of the state of the art is that the fixing of the roasting panels is not easy and depends on the diameter of the wire of the mesh. Another disadvantage is that although editing is not easy, dismantling the fence is possible, which makes it vulnerable to malicious intrusions. Finally, it is not possible to make a depth adjustment of panels or to vary the angle formed by the posts and panels.

An object of the invention is then to provide a simple barrier fixing device, allowing a deep adjustment of the barriers and the possibility of varying the angle between a post and a barrier, and conferring a certain security by making disassembly difficult roasting panels.

An object of the invention is a pole having a longitudinal direction, characterized in that it comprises internal and parallel surfaces vis-à-vis one of the other and, on each of these internal surfaces, notches oriented in the longitudinal direction of the pole.

Advantageously, the post has a constant section I-shaped with a core - central part - connecting two wings perpendicular to the latter, each wing forming an inner surface carrying the notches.

According to a particular embodiment of the post, the post comprises grooves adapted to accommodate at least one member for fixing a bar element.

Another object of the invention is a fastening clip characterized in that it comprises a central portion, two opposite ends and has an elasticity allowing its opposite ends to approach one another.

Thus, a barrier is trapped between the pole and the clip when the latter is positioned on the pole.

According to a particular embodiment of the clip, the opposite ends are bent so as to be applied against the internal surfaces of the pole.

According to a particular embodiment of the clip, it has complementary notches to those of the inner surfaces of the pole, preferably on its bent ends, if any.

Thus, the complementary notches collaborate with the notches of the post in order to achieve a secure fixation.

According to a particular embodiment of the clip, the central portion comprises at least one corrugation.

An advantage of the corrugation is that it provides the possibility of setting the position of the wire mesh wire in the width of the pole, for example to vary the angle between the barrier and the pole.

According to a particular embodiment of the clip, the corrugation consists of a central corrugation.

According to a particular embodiment of the clip, the corrugation consists of an angle corrugation located at each of the two angles formed by the central portion and the corresponding inner surface.

An object of the invention is a device for fixing barriers, characterized in that it comprises a pole and a clip according to any one of the preceding claims and in that the distance between the two internal surfaces is such that the clip is forced between the two inner surfaces by elastic deformation and is held in position in the post by its opposite ends retained in the notches.

Thus, it is possible to perform a deep adjustment of the barrier during the nesting of the clip on the pole through the interaction between the series of notches on the clip and the post. In addition, this depth adjustment allows the support of barriers of several diameters, for example 4, 5, 6 or 8 mm.

According to a particular embodiment of the barrier fixing device, the notches of the post and / or the complementary notches of the clip have a shape adapted to allow a fixation by irreversible interlocking preventing any removal of the fixing clip mounted in the post.

One advantage of the shape that is suitable for fixing by irreversible engagement is that the device is tamper-proof, in the sense that the dismantling of a panel is made impossible.

An object of the invention is an assembly of a barrier fixing device as described above and of a member for fixing a bar element, characterized in that the fastener is sized to slide in the grooves of the post.

According to a particular embodiment of the assembly of the barrier fixing device and the fixing member of a bar member, the fixing member comprises a point of weakness capable of allowing the passage of a self-drilling screw. .

According to a particular embodiment of the assembly of the barrier fixing device and the fastener of a bar element, the post comprises: external faces transverse to the general plane of the fence, bordered by the grooves and longitudinal external faces to the general plane of the fence and wherein the fastener member has a bearing face against the post of complementary shape to that of the longitudinal outer faces of the post.

Thus, it is possible to fix bar elements on all four sides of the pole.

The invention will now be described with reference to the following examples, which are not limiting in nature. The invention will be better understood on reading the appended figures, which are provided by way of example and are not limiting in nature, in which: FIG. 1 represents, in perspective, the upper part of a post carrying two panels. FIG. 2 is a view in section from above of FIG. 1, FIG. 3 is a view similar to that of FIG. 2, showing two other panels mounted differently, FIG. the upper part of another post bearing two other roasting panels, - Figure 5 is a sectional view from above of Figure 4, - Figure 6 is a view similar to those of Figures 2, 3 and 5 showing the Figure 7 is a detail view VII of Figure 6, Figure 8 is a perspective view of a clip, Figure 9 is a sectional view of IX-IX of Figure 8; FIG. 10 is a view of detail X of FIG. 9; FIG. 11 is an analog view. Figure 12 is a view similar to that of Figure 11, of another post; Figure 13 is a perspective view of a fastener; FIG. 14 is a sectional view along line XIV-XIV of FIG. 13, FIG. 15 is an elevational view of the fastener of FIGS. 13 and 14, FIG. is a view, in perspective and in partial section, of a post comprising a plurality of members for fixing a bar element, - FIG. 17 represents, in perspective, a post fixing foot, - FIG. 18 represents the base. of the foot of Figure 17, - Figure 19 shows the mast of the foot of Figure 17.

The post 1 of FIGS. 1 and 2 is an extruded piece of constant cross-section, of generally capital I-i shape with bars at the ends.

In this example, the section comprises a core 3 which corresponds to most of the width of the post 1 and, at each end of this core 3, a flange 5 perpendicular to the core 3.

The post 1 is symmetrical, in the sense that it has two sides mirror one of the other. On each side, the post 1 has two internal surfaces 7, namely a first inner surface 7a and a second inner surface 7b, parallel and vis-à-vis each other, since each wing 5 forms the two opposite internal surfaces 7 on either side of the core 3. In view of this symmetry, only one side of the post 1 and a single panel are described below and the references of parts or parts of parts are reported symmetrically in the figures.

On each of its internal surfaces 7, the post 1 can receive the edge of a panel 9.

The extruded post 1 is here a hollow body, but it could be replaced by an I-beam, whose core would serve as an internal surface by its two faces, for both sides of the post 1.

The panel 9 is a mesh, formed by welding of metal son 13 which are then usually galvanized or coated with a waterproof layer, such as a plastic or a paint. The panel 9 may also be for example a solid panel. The shape of the panel 9 may vary, including its thickness. It can be seen that the panel 9 shown in FIG. 1 has a longitudinal projection 11.

The metal wires 13 of the panel 9 are here oriented in two perpendicular directions, one horizontal, the other vertical, in the use position of the panel 9. In FIG. 1, three horizontal wires 15 and a dozen vertical son 17, including a border wire 17a.

This border wire 17a is used for fixing the panel 9 on the post. This attachment is performed using a clip 21 which traps the border wire 17a against the inner surface 7a of the post.

More specifically, as seen in the section of FIG. 2, the clip 21 comprises a central portion 23 and two opposite ends 25. The opposite ends 25 are bent so as to be applied against the inner surfaces 7 of the post . The distance between these opposite ends 25 is such that the clip can be forcefully introduced between the inner surfaces 7 of the post. In other words, the overall length of the clip 21 is slightly greater than the distance between the inner surfaces 7 of the post.

The clip 21 has an elasticity allowing its opposite ends 25 to approach each other slightly. The clip 21 can be imparted elastically by producing it in a sufficiently flexible material and taking advantage of the wavy shape of its central portion 23, as described below.

The inner surface 7a is provided with notches 27 substantially parallel to the longitudinal direction of the post 1 and arranged so as to be able to retain one of the opposite ends 25 of the fastener clip 21 by housing this end between two adjoining notches 27a, 27b.

In the example, the clip 21 comprises, on each of its opposite ends 25, additional notches 29 at the notches 27 of the inner surfaces 7 of the post 1. The interlocking of the notches 27 with the complementary notches 29 favors the retention of the opposite ends 25 of the clip 21 in the post 1, by anchoring several complementary notches 29 between contiguous notches 27 of the post 1. The notches 27 and the complementary notches 29 are all inclined in the direction of a recoilless progression of the clip 21 towards inside the post 1. Recoil means the fact that it would alter or even destroy the clip or the post 1, to retract the clip 21 towards the outside of the post, exerting an abnormally high force .

Thus, it is understood that the implementation of the clip 21 is a relatively simple operation: simply present the clip 21 in front of one side of the pole, between the two inner surfaces 7, and push it inwards, forcing to cross the notches 27 and complementary notches 29, until the clip 21 has reached its final position in the post 1.

In a very simple version (not shown) of the central part of the clip, this central part is flat. The border wire 17a of the panel 9 is trapped between said central portion and the post 1. The clip does not ensure the positioning of the border wire 17a in the width of the post 1, but this positioning can be provided by other means, for example by a width of the panel 9 substantially equal to the distance between the inner surfaces 7.

In the embodiment shown in the figures, the central part of the clip 21 comprises at least one corrugation 31, which is sized to house the edge wire 17a by imposing a position in the width of the pole 1. In FIG. the two clips - a clip 21 on each side of the post 1 - each comprise three corrugations, namely a central corrugation 31a and, at each of the two angles formed by the central portion and the corresponding inner surface, an angle ripple 31b. The central corrugation 31a of the clip 21 has a greater amplitude than the angle corrugations 31b.

In the position of the grid panel 9 of FIGS. 1 and 2, the edge wire 17a is immobilized by the clip 21 in an angle corrugation 31b. In this example, the panel 9 has a width less than the distance separating the two internal surfaces 7. Its position in the post 1 is entirely fixed by the clip 21.

In Figure 3, there is another panel 33 (two symmetry) consisting of horizontal son 35 and vertical son 37, including a border wire 37a. Unlike the panel of the previous figures, it is flat, that is to say that it does not have a projection. The post 39 is of generally identical shape to that of the previous figures.

In the position shown in Figure 3, the central corrugation 31a serves to immobilize the edge wire 37a in the middle of the width of the pole. This immobilization avoids the vibrations caused by the wind.

Note that the border wire 37a is slightly further away from the side of the pole than in the previous embodiment. This positioning is due to the structure of the panel 33, the horizontal son 35 protrude beyond the border wire 37a. This difference illustrates the flexibility of the clip 21, which can support small geometric variations of the panels without losing its effectiveness. The same applies to the diameter of the edge wire, which may vary slightly from one panel to another, for example in a range of 4 mm to 6 mm. This variation is absorbed by the positioning of the clip 21, which is less embedded in the post, by the flexibility of the clip 21 and the increased amplitude and the flared shape of the corrugation.

FIGS. 4 and 5 show a post 39 identical to that of FIG. 3. This post 39 cooperates with a clip 21 for fixing a panel 45 (two by symmetry) of a structure similar to the panel 9, except for greater spacing between the vertical wires along the horizontal lines. The greater amplitude of the central corrugation 31a makes it possible to place the panel 45 so as to make an angle between it and the post 39. contact with the web of the post 39 when positioned within the central corrugation 31a. These are angles of the ends of the two horizontal wires 49b which are in contact with the core of the pole 39 when the clip 21 is positioned, as illustrated in FIG. 5. It is then possible to vary the angle between the pole 39. and the panel 45 using one or other of the corrugations of the clip 21.

FIGS. 6 and 7 show a pole 50. The I-shape with the two wings 53 perpendicular to the core 55 is clearly visible. The wings 53 have on their internal surfaces 57 situated on either side of the core 55 a series of notches 27 substantially parallel to the longitudinal direction of the pole 50.

It is clearly seen in Figure 7 that the notches 27 have an identical shape with respect to each other. The inner faces 61 of the notches 27, that is to say those closest to the core 55 are perpendicular to the wings 53 while the outer faces 63 are inclined towards the core 55 with an angle less than 90 Relative to the wings 53. Thus, the clip 21, which has its complementary notches 29 to the notches 27, can be inserted into force on the pole 50 by interaction with the outer faces 63 and be retained by the internal faces 61 of the notches 27.

In Figures 8, 9 and 10, we see the clip 21 shown alone. The central portion 23 comprises a central corrugation 31a and two corner corrugations 31b distributed evenly along the length of the central portion 23. The angle corrugations 31b are of equal amplitude while the central corrugation 31a has an amplitude more important for the reasons mentioned previously (support for variable diameters of threads and possibility of varying the angle between the post and the panel). The opposite ends 25 have on their outer surface 65 the complementary notches 29 to the notches 27, this complementarity being illustrated in FIGS. 2, 3 and 5. The complementary external faces 67 of the complementary notches 29 allow the clip 21 to slide between the flanges 3 or 53 when interacting with the outer faces 63. When the clip 21 is positioned, the complementary inner faces 69 of the complementary notches 29 interact with the inner faces 61 of the notches 27 in order to retain the clip 21 in the pole as previously described.

As indicated above, the clip 21 is made of a material giving it a certain elasticity. It is for example made of aluminum.

The post may be adapted to have a different resistance depending on its size. Posts 1 and 39 previously described (hereinafter light poles) have a resistance of 155 kg at 1 m from the ground. Figure 11 shows an intermediate post 71 having wings thicker than previously presented posts (16 mm against 9.5 mm) to have a strength of 254 kg to 1 m from the ground. FIG. 12 shows a wide post 73 having wings even thicker than the intermediate post 71 (24.5 mm) and a core 75 thicker than the souls of the light posts and the intermediate post 71 (15.5 mm against 4, 40 mm) in order to have a resistance of 460 kg at 1 m from the ground.

The intermediate post 71 and the wide post 73 have a general structure similar to the poles described above (ie a core, wings perpendicular to the core and located on either side of the latter and notches arranged on the inner surface of the wings). However, grooves 77 are formed in the wings 79 of the intermediate post 71 and in the wings 80 of the wide post 73 at the junction between the latter and the core 76 of the intermediate post and the core 78 of the wide post. These grooves 77 allow the pole to receive a fixing member of a bar element which will be described later. The grooves are of constant section on the height of the post so as to form a slide for the fasteners of bar elements, which are described below. In addition to the fastening elements of bar elements (barred panels), the grooves can receive several other accessories to adapt to the pole other types of panels such as panel occlusions, fences glass panels, etc.

The intermediate post 71 and the wide post 73 may be equipped with fasteners 81 of bar elements, such as that illustrated in Figures 13 to 16. These fasteners 81 comprise a curved base 83 and two fins 85 perpendicular to the base 83 and extending from the same face of this base 83. A bar element (for example the high and low rails of bar elements) can be fixed to the fasteners 81 by simply interlocking on the fins 85 This assembly can be secured by hardware elements (self-drilling screw, self-breaking nut, rivets, ...).

The base 83 has two ends 87 of a shape allowing them to be inserted and slid into the grooves 77. In other words, the ends 87 are inserted into the grooves 77 and positioned at the desired sliding height. As illustrated in Figure 15, the fasteners 81 include, for example in the center of the base 83, a weak point 89 for the perforation of the fasteners 81 by a self-drilling screw. This makes it possible to fix the fasteners 81 as soon as they are placed at the desired height on the intermediate post 71 or the wide post 73.

The base 83 is curved, as is illustrated in FIGS. 13, 14 and 16. This shape enables the fastening members 81 to conform to the shape of the longitudinal external faces in the general plane of the fence 92 of the wings 79 of the intermediate post 71 and wide post 73, as illustrated in Figure 16.11 is thus possible to fix bar elements, a portion 93 is shown in Figure 16, at the four faces of the intermediate post 71 and the wide post 73.

The poles described above are fixed to the ground by means of a fixing foot 95 shown mounted and disassembled in FIGS. 17 to 19. The fixing foot is composed of a base 97 intended to be fixed to the ground. This base is here of trapezoidal shape (it may have any other form if any) and has 5 notches, three oblong slots 99 distributed around the periphery of the base 97 to ensure the attachment of the base 97 on the ground and two notches rectangular 101 located substantially in the center of the base 97 to allow attachment to the base of the second part of the attachment foot 95. It is a mast 103 of substantially rectangular shape. The mast 103 comprises two portions 105 projecting from one end 107 of the mast, these two portions being intended to be inserted into the rectangular notches 101 as illustrated in FIG. 17. The mast 103 also comprises two square notches 109 enabling the fixing a pole like those described previously.

When mounting a panel as shown in Figures 1 to 5, it starts by fixing at least one fixing foot 95 to the ground through the three oblong slots 99. One then fixes a pole among those previously described at the fixing foot 95 through the two rectangular notches 101.

A panel is then placed among those described above with respect to the post, as illustrated in FIGS. 1 to 5. Once the panel has been placed in the desired position, the panel is trapped in the post by the use of at least one clip 21. As explained above, the clipping is carried out by depressing the clip 21 on the post in order to force the complementary notches 29 to pass through the notches 27 until the clip 21 is positioned. The other end of the panel is fixed in the same manner to another post, post fixed as described above. This series of steps is repeated several times in order to mount the complete screen.

It is possible to fix a pole, then to fix a panel on a pole and finally to fix a second pole to fix the free end of the panel. It is also conceivable to fix all the posts and then put the panels between the posts from above and finally to fix the panels on the posts through the clips.

In the case of a bar element, at least one post is fixed to at least one fixing foot 95 previously fixed to the ground, then at least one fixing member 81 is inserted into the slide formed by the grooves 77 of the post and blocks this fastener 81 at the desired height on the post using a self-drilling screw. A locking element (not shown) is then mounted by interlocking (which can be secured as explained above) on the fastener 81. Alternatively, the fastener 81 may be fixed to the outer surface 90 of the post, as illustrated in Figure 16.

Again, it is possible to fix a pole, then to fix a fastener 81 on a pole and finally to fix a bar element to the fastener 81. This operation is then repeated several times to achieve a fence . It is also possible to fix all the posts and then fix all the fasteners to the posts and finally fix all the bar elements to the fasteners. The invention is not limited to the embodiments presented and other embodiments will become apparent to those skilled in the art.
