Description

FIXING DEVICE FOR A CLOSING GRID ON A POST AND CLOSURE

IMPLEMENTING SUCH ORGANS

  The present invention relates to a fastening member of a fence fence on a post or post, traditionally used to erect such a fence. It also refers to a fence put in place by means of such bodies.

  A large number of fences are made from a grid, flexible or rigid, fixed on a plurality of posts or fence posts, substantially periodically distributed and erected along the perimeter to be fenced. These posts or fence stakes may, for example, consist of metal sections in T or L-shaped cross-section. The mesh used may be a flexible grid, with single, double or triple torsion, formed from threads, generally of metal, of square, rectangular or diamond-shaped mesh. The choice of the combination of the mesh, the diameter of the wire and the mode of torsion depends on the required solidity. A second type of grid, rigid this time, is formed from welded wire mesh, rectangular mesh.

  Conventionally, the flexible screens assume the prior establishment of one or more tension son provided with tensioner, extending substantially horizontally between the various aforementioned columns. These tension son are particularly likely to be received at each of said posts in a through hole.

  The rigid type of screens are, in turn, generally attached to said posts by means of a clip or a collar from gripping one of the son that constitute them with said poles.

  It is known from EP A - 0.481.100 a clamping clamp being positioned on the tip of a fence rod substantially triangular. Orifices are provided at the tip, to allow the maintenance of this flange by screwing on the stake.

  However, this flange mount allows only a height adjustment in successive discrete steps, following the orifices. In addition, this attachment is provided for the attachment of tension son on which is secured the actual wire mesh.

  Also known from US-A-5,676,351 a fixing system of a fence to a post, implementing a member which is snapped into an opening in the post. The member comprises two lateral tabs which maintain by plating one or more son of the mesh against a flat area of the stake.

  The disadvantage of this system lies in the fact that there can be no precise adjustment in height. In addition, the adjustment that can be obtained is discrete, because imposed by the number of orifices and the spacing between them. In addition, this fixing system by wedging does not seem reliable, slippage between the legs of the body and the son or son of the grill may occur.

  It is known from documents FR A - 2.686.640 or DE A - 34.22.049 a clip to be fixed at a desired height on the profile of a post. This clip is intended to allow insertion of son kept under tension belonging to traditional screens. The son are thus maintained by being pressed against one side of the amount.

  However, this clip fastening system only allows the securing of the wire and not a grid. In addition, this system is not self-locking, both with respect to the post and relative to the wire. Indeed, in case of heavy stress, this clip can move along the pole and the wire can also slide under the clip. Finally, because of the direct friction, this system leads to wear or local oxidation phenomena of the wire, the staple and the post.

  A first objective that the invention proposes to achieve is to obtain a member for installing and fixing a screen, capable of adapting to all types of screens and all types of posts or posts.

  A second objective that aims to achieve the invention lies in the realization of a member for setting and fixing the mesh, capable of easily allowing the height adjustment of the mesh relative to the stake.

  A third objective of the present invention lies in the development of a fixing member which does not damage the wire of the grid, or the amount or post 35 on which is fixed the grid.

  A fourth objective of the present invention is the rapid assembly of a fence with a fence attached to posts or fence posts, and adapted to all configurations encountered in the field.

  According to a first aspect of the invention, the fastening member of a fence fence on a post made of a T-shaped cross section profile comprises: E a first element able to snap onto the profile constituting said post and having at least one housing for receiving one of the son forming part of the grid or participating in its fixing, and E a second cover member for cooperating with said first element, and coming to close the housing of the latter so as to maintain said wire forming part of the grid or participating in its fixing within this housing.

  In other words, the invention makes it possible, by means of said first element, to easily assemble by simple snapping on the fence post of a fixing means, the height of which can be freely selected by the user, by the fastening retained. The tension wire of the mesh or the wire of the mesh itself, whether flexible or rigid, is placed inside the housing of the first element. The second element then firmly secures the wire of the wire mesh by blocking this wire in the first element and thus on the fence post considered.

  According to the invention, said first element comprises two independent parts intended to cooperate with each other, respectively: E a main part, provided on one of its faces with one or more housings intended to receive the wire of the mesh or the tensioning wire of the mesh, and on its other face a hook intended to cooperate with the constituent section of the pole; É and a staple, also provided with a hook intended to cooperate with the constituent section of the post, ensuring by its cooperation with said main part, the snap of said first element on the constituent section of the post.

  According to a characteristic of the invention, the constituent body of the main piece has a slot inside which is housed a free tab of the clip.

  According to another characteristic of the invention, the free tab of the clip is provided near its end with a pin, capable of being deployed laterally and intended to cooperate with a projection formed inside the slot of the clip. main piece, said projection may be constituted by a rack. This particular architecture thus allows an adaptation of the body to all types and dimensions of profiles.

  The main piece and the staple may have a shape complementary to the constituent section of the fence post. In this case, the constituent body of the main piece is pressed against the upper bar of the T, and the respective hooks of the main part and the clip come to grip the free ends of the upper bar T. These hooks are for example constituted by the curved flange, in particular U-shaped, respectively of the main part and the staple.

  The second cover member is advantageously provided with one or more pins, intended to allow its easy attachment by snapping into holes, through or blind, provided for this purpose within the body of said main part.

  In addition, in order to allow an adaptation of the member according to the invention to several mesh sizes, the second cover member may have two fixing positions on the first element, defined by the location of said pins, the two positions. drifting from each other by simply rotating said lid 180 on itself.

  According to a second aspect of the invention, a fence comprising T-shaped cross-section profiles and a grid is characterized in that at least one of the constituent wires of said grid or participating in its installation is fixed. on the profiles using one or more fasteners of the type of those described above.

  The invention will be better understood and its various advantages and different characteristics will emerge more clearly from the following description of the nonlimiting exemplary embodiment, with reference to the appended diagrammatic drawings, in which: FIG. 1 represents an exploded perspective view the member for fastening a flexible grid by means of a tensioning wire according to the invention; Figure 2 shows an exploded perspective view of the fastener of a square mesh or rectangular mesh, in accordance with the invention; - Figure 3 shows a top view, also exploded of the fixing member of the invention mounted on a fence post; - Figures 4, 5 and 6 respectively show a side view, a view from above and a front view of the main part forming part of the first element of the fastener of the invention; Figure 7 shows a side view of the clip also forming part of the first element of the fastener of the invention; and Figure 8 shows a top view of the lid.

  Traditionally, the establishment of a fence consisting of a flexible type of wire mesh (not shown in detail) imposes the tension of a so-called tension wire (1) between posts or fence posts (2), erected at more or less regular or periodic intervals. This or these tension son are fixed on these poles (2), at least two son tension in the same vertical plane, to give some strength to the fence in addition to some resistance.

  On the other hand, when the fence consists of rigid type grid panels (3), specific pieces of shapes adapted to the geometry of said panels and to the geometry of the stakes or posts are fixed to the post or post (2), also in several places in the same vertical plane, to ensure the mechanical connection between the rigid type of grid panels and the stakes or poles.

  The peg (2) consists of a metal section or T-shaped cross-section composite material that can be obtained by means of rolling, extrusion or profiling ..., and this so known. This peg (2) has two flat portions, perpendicular to each other, respectively the upper bar (7) of the T, and the base (8), ie the classically vertical element of the T If the upper bar (7) of the T is generally linear or plane, its two ends or free edges (9, 11) may be slightly bent towards the base (8), as for example described in FIG. document FR03 / 09638 of the Applicant.

  A standard fastening member (12), according to the invention, is used to ensure the laying and the firm fixing of the tension wire (1) or the wire or wires (6) of the grid (3) at the level of the posts (2).

  According to the invention, this member (12) comprises firstly, a first element ensuring its attachment to the post (2), and consisting of a main part (13) and a clip (14), and secondly a second element acting as a cover (16), intended to be reported, possibly reversibly, on said first securing element.

  The main part (13), for example made of plastic or composite material by injection, for example made of polyamide and fiber or glass beads, is in the form of a parallelepiped or a rigid plate (see FIGS. 6), provided with a flat bottom (17), intended to be pressed against the apparent surface (18) of the upper bar (7) of the T-section. The face (20) opposite to the flat bottom (17) of the main part (13) has a continuous groove (19) forming a housing for receiving and housing the son or son (1, 6).

  One edge of the wafer constituting the main piece (13) has a curved protrusion U-shaped (21) forming a hook, returning partially cover the edge of the flat bottom (17). In the example described, the width of this protrusion (21) substantially corresponds to the offset induced by the bending of the curved free ends (9) of the upper bar (7) of the T of the stake (2), as well as observe it in Figure 2. The free end (9) curved is housed in the bottom of the U of the projection (21) of the main part (13). The hook-shaped U-shaped protuberance (21) is in fact a first point of attachment of the first element on the stake (2).

  Said main piece (13) further comprises a slot (22) formed at its side face (23) of the constituent wafer, opposite to the side face adjacent to the U-shaped end (21). The slot (22) opens into an internal volume defined within the wafer, and having a rack (24) de-creasing a series of projecting notches. The rack (24) is visible and accessible from the face (20) of the main part (13), through an opening (26) opening into the volume accessible through the slot (22).

  This main piece (13) is intended to cooperate with a staple (14), hereinafter described in more detail. This clip (14) is in the form of a hook and is made of a flexible material in the plane perpendicular to the vertical axis of the post or stake, for example metal made of spring steel (see Figure 7), but however rigid in the other plane. The clip (14) thus comprises a first lug or elongated blade (27), extending by a curved protrusion U-shaped (28) partially returning to cover the edge of the blade (27), and constituting the aforementioned hook. The curved protrusion U-shaped (28) has in the vicinity of its free end two lateral lugs (29), extending substantially perpendicular to the plane defined by the clip. In addition, these lateral lugs (29) define by construction an angular and pointed zone (30), directed towards the bottom of the U constituting this outgrowth.

  In the example described, the width of this protrusion (28) substantially corresponds to the offset induced by the bending of the curved free ends (9) of the upper bar (7) of the T of the post (2), so that one can well see Figure 2. The curved free end (11) is housed at the bottom of the U of the protuberance (28) of the clip (14). The hook-shaped U-shaped projection (28) is in fact the second attachment point of the first element on the stake (2).

  Thus, the cooperation of the staple (14) with the main part (13) allows it to define two attachment points, able to locate the actual locating position of the fastener of the invention at any point of the stake (2), and no longer at more or less regular intervals, and in any case discrete of the prior art.

  For this purpose, the elongate blade (27) of the staple (14) has a width and a thickness compatible with the dimensions of the slot (22) of the main part (13), in order to allow its insertion within the -this.

  In addition, a lug (31), derived from cutting, unfolds from the elongated blade (27) in the vicinity of its free end, and towards the U-shaped protrusion (28). Thus, when the elongate blade (27) is inserted into the slot (22) of the main part (13), the lug (31) cooperates with one of the notches of the rack (24), inducing the locking of the staple (14) on the main part (13). By this locking, the lug (31) prevents any exit of the blade (27), and therefore of the clip (14) from the slot (22) and thus any separation of the clip (14) of the main room (13). The lug (31) positioned between two notches of the rack (24) ensures a snap of the clip (14) on the main part (13).

  The rack (24) allows an adaptation of the length of the member (12) to several dimensions of the upper bar (7) of the peg (2).

  When the staple (14) is thus secured to the main piece (13), the two U-shaped protrusions (21, 28), respectively of the main piece (13) and the staple (14), thus enclose each free ends (9, 11) of the two wings of the upper bar (7) of the T of the peg (2).

  Moreover, the physical principles used, in this case action reaction, induce the attempt to withdraw the clip (14) out of the slot (22), and thus corollary the recoil of the U-shaped outgrowth (28) in the direction of the upper bar (7) of the T, but in a direction away from the base (8). As a result, the angular and pointed zones (30) tend to penetrate into the curved wing (11) of the upper bar (7) of the T, thus favoring the anchoring of this point of attachment. This anchoring is further optimized, when the metal section constituting the post (2) is coated with one or more layers of paint.

  In addition, the relatively flexible nature of the clip (14) allows the adaptation of the fastener of the invention to any type of T-profile, including any type of inclination of curved flanges of the bar upper (7) of said T. The second element forming part of the fastener of the invention is constituted by a cover (16). This has dimensions complementary to those of the main part (13) (see Figure 8). The lid (16) closes the housing (19) when the wire (1, 4 and 6) is inserted therein. The lid (16) is provided with a plurality of pins (32) projecting towards the main piece (13). The pins (32) are intended to be inserted into blind holes (33), provided for this purpose within the face (20), thus allowing a 180-angle pivoting of the lid (16) on the main room (13).

  The positioning of these orifices (33) within the face (20) of the main part (13) is chosen to allow a certain latitude of cooperation with the cover (16). Indeed, during the establishment of the rigid mesh, a vertical wire (4) constituent is likely to interfere with the positioning and maintenance of the lid (16). A pivoting 180 of this cover (16) on itself allows to shift the place of cooperation thereof with the main part (13), and therefore not to be bothered by this vertical wire. Indeed, as can be seen in Figures 1 and 5, the face (20) of said main portion (13) is provided with two sets of four orifices (33), offset with respect to the other of the value of about one diameter of said orifices.

  It will be understood the great ease of implementation of the fastener of the invention. A simple insertion of the staple (14) within the lateral slot (22) of the main part (13), followed by a manual tightening, makes it possible to locate at the desired height the first element of the fastener .

  Of course, the user positions said first element as a function of the mechanical stresses or localization of the son or tension or constituent of the flexible mesh or rigid panel that he is brought to meet.

  In the case of flexible mesh, once this first element positioned, it only remains for him to introduce the tensioning wire, or the wire of the mesh retained in the housing (19) of the main part (13) of said first element , then to close it by bringing the cover (13) to this level.

  In the case of rigid type grid panel, once this first element is positioned, it only remains for him to put in place a support plate, not detailed here, of said rigid panel, in the housing (19) of the main part. (13) of said first element, then to close it by bringing the cover (13) to this level.

  The present invention is not limited to the embodiments described and illustrated. Many modifications can be made, without departing from the scope defined by the scope of the set of claims.
