    ACCESSORY FOR FIXING A GRILL PANEL TO A FENCE POST COMPRISING A LOCKING PIECE AND A CLAMPING PIECE
    Technical area
    The present invention relates to the field of fences comprising mesh panels, in particular mesh-welded mesh mesh panels, which are constituted by the assembly of spaced vertical rods or spaced vertical wires, commonly known as "chains" or "wires. warp "and spaced horizontal rods or spaced horizontal threads, commonly known as" wefts "or" weft threads ". In this area, the main object of the invention is a new fixing accessory allowing the fixing of a mesh panel to a fence post while being positioned in a longitudinal groove of this fence post.
    Prior art
    There are different known types of fixing accessory allowing the fixing of a grid panel to a fence post while being positioned in a longitudinal groove of this fence post.
    In international patent application WO2010 / 121789, the fixing accessory comprises a blocking piece comprising an internal face, which is intended to be fixed in abutment against the bottom wall of the longitudinal groove of a fence post, and in which is formed at least one open housing, which extends in length and is capable of receiving a portion of a warp wire (vertical wire or vertical rod) end of a mesh panel. This finishing accessory also necessarily includes a fastening element for this blocking piece in the groove of the fence post, for example a threaded rod with self-breaking nut, which is designed to be passed through the blocking piece and the wall. the bottom of the fence post groove. The mesh panel is fixed to the fence post by means of at least one fixing accessory, with a portion of the end warp wire of the mesh panel positioned in said housing of the workpiece.
    BE2019 / 5481 blocking and the blocking piece being fixed in abutment against the bottom wall of the groove of the fence post, so that said end chain wire of the grid panel is blocked between the blocking piece and the wall of bottom of the fence post groove.
    In the French patent application FR 2 908 440, the fixing accessory comprises a blocking piece, which in a manner comparable to the fixing accessory of the above-mentioned international patent application WO2010 / 121789 has an internal face, which is intended to be immobilized in abutment against the bottom wall of the longitudinal groove of a fence post, and in which is formed at least one open housing of the groove type, which extends in length and is capable of receiving a portion of a chain wire (vertical wire or vertical rod) at the end of a wire mesh panel. However, unlike the solution described in this international patent application WO2010 / 121789, the fence post comprises, facing the bottom wall, two longitudinal retaining projections oriented towards the inside of the longitudinal groove; the blocking piece is elastically deformable so as to be able to be fully inserted by force into the groove of the fence post by pivoting it and by exerting sufficient pressure on this piece to deform it and make it completely penetrate into the groove of the throat post. Once completely inserted into the post groove, this blocking piece is immobilized by self-tightening between the retaining projections and the bottom wall of the post groove.
    Compared with the fixing accessory described in the international patent application WO2010 / 121789, the fixing accessory described in this French patent application FR 2908 440 has the advantage of not requiring the use of an element of fixing passed through the blocking piece and the bottom wall of the post groove. However, in practice the deformation of the blocking piece requires the implementation of a significant mechanical pressure, which makes the operation of inserting by hand this blocking piece into the groove of the post very difficult for the fence installer. In practice, we are forced with this type of solution to use a
    BE2019 / 5481 tool, pliers type, for forcibly inserting said blocking piece into the groove of the post.
    In addition, it frequently happens that during installation, the fence installer is forced to dismantle part of the fence to reassemble it, in particular to better take into account a difference in level or a slope of the ground. With the solution described in the above-mentioned French patent application FR 2 908 440, once the blocking piece is inserted into the groove, it is difficult to remove it, which in the event of incorrect positioning of the blocking piece or in the event of the need to dismantle / reassemble the fence complicates operations for the installer.
    In French patent application FR 2 908 439, the attachment accessory comprises a blocking piece, which in a manner comparable to the attachment accessory of the abovementioned international patent application WO2010 / 121789 or to the French patent application FR 2 908 440 above mentioned has an internal face, which is intended to be immobilized in abutment against the bottom wall of the longitudinal groove of a fence post, and in which is formed at least one housing which extends in length and is able to receive a portion of a warp wire (vertical wire or vertical rod) end of a mesh panel. However, unlike the solution described in French patent application FR 2 908 440, the blocking piece is designed so as to be easily inserted into the groove of the fence post and to be blocked with play in the groove. between the bottom wall and the retaining projections by rotating it by an angle of 90 °. Once inserted and rotated by 90 °, the blocking piece is not immobilized in the groove and can slide longitudinally in the groove because of the play in the groove imposed by its pivoting by 90 °. Thus in this solution, in a manner comparable to the attachment accessory of the above-mentioned international patent application WO2010 / 121789, it is essential to fix the blocking part in the groove of the post by means of a fixing element passing through the part. blocking and bottom wall the throat of the fence post.

    FIGS. 15 to 21 respectively illustrate the main stages of fixing the end warp wire of a wire mesh panel to a fence post by means of the fixing accessory of FIG. 2.
    detailed description
    FIG. 1 shows an accessory 1 in accordance with the invention and used to fix a mesh panel 2 to a fence post 3.
    The fence post 3 has two opposite faces, each having a longitudinal groove 30. Each longitudinal groove 30 is delimited by a bottom wall 30a, two longitudinal retaining projections 30c, which extend over the entire height of the post 3 vis-à-vis opposite the bottom wall 30a, and two front or rear connecting walls 30b which are opposite one another and which respectively connect the two retaining projections 30c to the bottom wall 30a .
    In the particular embodiment of FIG. 1, the mesh panel 2 is a rigid panel of the lattice-welded type, constituted by spaced vertical rods 20, commonly designated “chains” or “chain wires” welded to rods. horizontal 21 spaced apart commonly known as "wefts" or "weft son". In this particular example, the panel 2 is of the pleated panel type, each vertical rod 20 (warp thread) forming a V-fold in the upper part and if necessary in the middle part and / or in the lower part.
    The invention is not limited to pleated panels, but extends to any type of known mesh panel comprising warp threads
    BE2019 / 5481 spaced apart, and can in particular also be applied to straight panels in which the vertical rods (warp threads) are rectilinear over their entire length. The grid panel can also be of the “double wire” type, that is to say comprise pairs of weft yarns spaced vertically, the weft yarns of a pair being fixed at the same height on both sides. other warp threads.
    The fixing accessory 1 comprises two separate parts 10, 11, which in FIGS. 2 to 5 are positioned one on the other, namely a clip 10 having a function of blocking part (FIGS. 6 to 9), and a counter clip 11 (FIGS. 10 to 13) having a clamping part function.
    Figures 6 to 9 - Locking piece 10
    The locking piece 10 is a flat piece having a central axis of symmetry 10a, and having an outer face 100, intended to be oriented towards the clamping piece 11, and an inner face 101, intended to be oriented towards the fence post. 3. This blocking piece 10 has a length L10 and a width lw measured in a plane (X, Y) perpendicular to its central axis of symmetry 10a (FIG. 7),.
    In the internal face 101 of the locking piece 10 are formed four open rectilinear housings 102A, 102B, 102C, 102D, which are each delimited by a rectilinear groove having a U-shaped profile and which extend parallel to each other. other in the direction Y of the width of the blocking piece and over the entire width of the blocking piece 10.
    The two housings 102 A and 102D are symmetrical to each other with respect to a central plane of symmetry 10b (FIG. 8) of the locking piece 10 and the two housings 102B and 102C are symmetrical to one another. other with respect to said central plane of symmetry 10b. This symmetry of each pair of housings 102A / 102D-102B / 102C advantageously allows greater flexibility in mounting the blocking piece 10 in the groove of a fence post 3 with two possible mounting directions.
    The two extreme housings 102A and 102D have more
    BE2019 / 5481 particularly a shallower depth than the other two housings 102B and 102C.
    Each housing 102A, 102B, 102C, 102D is dimensioned so as to be able to receive a portion of an end warp wire 20 from a grid panel 2.
    Preferably, but not necessarily, the dimensions of each housing 102A, 102B, 102C, 102D can be adapted to the diameter of the end warp wire 20 of the mesh panel 2, so that said end warp wire can be inserted into the housing 102A, 102B, 102C, 102D with a tightening of the locking piece 10 on the warp thread. Thus, when the warp thread is inserted into the housing 102A, 102B, 102C, 102D, the blocking piece 10 is held relative to the warp thread and does not slide under the effect of its weight relative to the warp thread .
    Generally, in the context of the invention, the number of housings of the blocking piece 10 is unimportant, the main thing being that the blocking piece 10 comprises at least one open housing capable of receiving with clamping or without tightening, the extreme chain wire 20 of a grid panel 2.
    In the particular variant of the appended figures, the blocking piece 10 is preferably resiliently deformable to facilitate its elastic fitting in the groove 30 of the fence post 3.
    Preferably, this deformation can be obtained by hand when mounting the blocking piece 10 in the groove 30 of the fence post 3, without requiring the use of a specific tool.
    More particularly, in the particular embodiment illustrated in the figures, this deformation of the locking piece 10 is made possible by the use of two clamping lugs 103, which are elastically deformable in a plane parallel to the plane (X , Y), so as to allow, in the deformed state, a reduction in the length L10 of the locking piece 10.
    Thus, in the absence of mechanical stress, the length L10 of the
    BE2019 / 5481 blocking piece 10 at rest in the non-deformed state (FIG. 7) is maximum (Lio = Lmax). This maximum length Lmax is chosen so that it is slightly greater than the maximum spacing Emax (FIG. 14) between the two connecting walls 30b of the groove 30 of the fence post.
    The elastic deformation of the two clamping lugs 103 allows a sufficient reduction in the length L10 of blocking piece 10 to allow its elastic fitting into the groove 30 of the fence post 3 between the two connecting walls 30b (FIG. 14), such that this will be described in more detail later.
    More particularly, the width lw of the blocking piece 10 is less than the minimum spacing Emin (FIG. 14) between the two retaining projections 30c and the length L10 of the blocking piece 10 at rest (L10 = Lmax) is greater. at the minimum spacing Emin (FIG. 14) between the two retaining projections 30c.
    More particularly, to facilitate its deformation in contact with the connecting walls 30b of the groove 30, the blocking piece 10 has four rounded corner edges 106A, 106B, namely (FIG. 7):
    - two corner edges 106A which are diametrically opposite with respect to the central axis of symmetry 10a of the locking piece 10 and which are rounded so as to form curved bearing surfaces in the thickness of the locking piece convex diametrically opposite with respect to the central axis of symmetry 10a of the locking piece 10 and
    - two other corner edges 106B which are diametrically opposite with respect to the central axis of symmetry 10a of the clamping piece and which are rounded so as to form convex curved bearing surfaces diametrically opposite with respect to the axis of central symmetry 10a of the locking piece 10.
    Preferably, but not necessarily, the two clamping lugs 103 are symmetrical to each other with respect to the central axis
    BE2019 / 5481 vertical 10b of the locking piece 10.
    In another variant, the blocking piece 10 may have only one clamping tab 103.
    The invention is not limited to the particular variant embodiment of the locking piece 10 with deformable clamping lugs 103, nor to an assembly of this locking piece by rotation.
    In another variant, the clamping lugs 103 can be replaced by any equivalent means fulfilling the same function.
    The blocking piece 10 could also be designed to be inserted into the groove 30 without pivoting on itself and for example by simple translation in the direction of the bottom wall 30a of the groove 30.
    In another variant, the blocking piece 10 could also be non-deformable.
    The locking piece 10 is not necessarily symmetrical, the central axis 10a not necessarily being an axis of symmetry of the part.
    Preferably, but not necessarily, the blocking piece 10 has a central cylindrical through hole 104 (FIGS. 5 and 6) which allows, if necessary, the passage of a fixing piece of screw type, through the blocking piece 10.
    Preferably, but not necessarily, the blocking piece 10 comprises in its external face 100, a hollow female imprint 105 capable of cooperating with a male imprint in relief of the clamping piece 11, for the blocking in rotation of the piece of tightening 11 relative to locking piece 10 around a central axis 1a of the fixing accessory 1, when the two pieces 10 and 11 are aligned in their final fixing configuration of FIG. 1.
    The locking piece 10 is preferably a single piece which can be manufactured by any known means and for example by molding or by 3D printing.
    The material of the blocking piece 10 is of no importance for the invention. In a non-limiting and non-exhaustive manner, the piece of
    BE2019 / 5481 blocking 10 can be made of plastic, and for example polyamide 6. The blocking piece 10 can also be made of metal or a metal alloy, and for example a metal alloy, in particular zinc alloy, aluminum, magnesium and copper, Zamak type.
    Figures 10 to 13 - Clamping piece 11
    The clamping piece 11 is intended to be inserted in part between the locking piece 10 and the two longitudinal retaining projections 30c of the groove 30 of the fence post 3.
    The clamping piece 11 is a flat piece which has a central axis of symmetry 11a, which has an outer face 110 and an inner face 111 intended to be oriented towards the locking piece 10. This clamping piece
    It has (FIG. 10) a length L11 and a width I11 measured in a plane perpendicular to its central axis of symmetry 11a.
    More particularly, as for the locking piece 10, the width
    III of the clamping piece 10 is less than the minimum spacing Emin (FIG. 14) between the two retaining projections 30c, so as to facilitate its introduction into the groove 30 of the post 3. The length L11 of the clamping piece 11 is greater than the minimum spacing Emin (FIG. 14) between the two retaining projections 30c, but is less than the minimum spacing E'min between the two connecting walls 30b (FIG. 14)
    The clamping piece 11 comprises, in two diametrically opposite angles, two curved edges 112A symmetrical to one another and diametrically opposite with respect to the central axis of symmetry 11a of the clamping piece. Each curved edge 112A forms in the thickness of the clamping piece 11 a convex curved face.
    The clamping piece 11 also comprises, in two other diametrically opposite angles, two curved edges 112B symmetrical to one another and diametrically opposite with respect to the central axis 11a of the clamping piece. Each curved edge 112B forms in the thickness of the clamping piece 11 a convex curved face.
    Each curved edge 112A is connected to a curved edge 112B by a
    BE2019 / 5481 edge 112C substantially straight and is connected to the other curved edge 112B by an edge 112D substantially straight.
    The curved edges 112A make it possible to facilitate the insertion of the clamping piece 11 between the blocking piece 10 and the two longitudinal retaining projections 30c of the groove 30 of the fence post 3, by rotation of the clamping piece 11 on itself. in a first direction of rotation R1 FIG. 10) around the central axis 11a of the clamping piece.
    The curved edges 112B make it possible to facilitate the insertion of the clamping piece 11 between the blocking piece 10 and the two longitudinal retaining projections 30c of the groove 30 of the fence post 3, by rotation of the clamping piece 11 on itself. in an opposite direction of rotation R2 (FIG. 10) around the central axis 11a of the clamping piece.
    The external face 110 of the clamping piece 11 also comprises at its periphery two clamping ramps 113 which are diametrically opposite, and which are preferably identical and symmetrical to each other, with respect to the central axis 11a of the clamping piece 11.
    These two clamping ramps 113 have the function of allowing progressive clamping of the clamping piece 11 between the blocking piece 10 and the two longitudinal retaining projections 30c of the groove 30 of the fence post 3, during the rotation of the clamping piece 11 in one or other of the above-mentioned directions of rotation R1 or R2.
    More particularly, each clamping ramp 113 has a central portion 113a which defines a substantially flat clamping surface and parallel to the central axis 11a, at which the thickness e of the clamping piece 11 is maximum (e = emax / figure 12). This central portion 113a is extended at each end by an inclined portion 113b whose upper face forms a slope and at the level of which the thickness e of the clamping piece 11 gradually decreases from the central portion 113a corresponding to the maximum thickness Emax up to a minimum thickness Emin (figure 12).
    With reference to FIGS. 5 and 13, the clamping piece 11 comprises
    BE2019 / 5481 in its internal face 111, a raised male imprint 114 able to cooperate with the abovementioned female imprint 105 above of the clamping piece 11, for locking in rotation of the clamping piece 11 relative to the piece blocking 10 around a central axis 1a of the fixing accessory 1.
    Preferably, but not necessarily, the clamping piece 11 has a central through hole 114, preferably of non-circular cross section, which if necessary allows the passage of a fixing piece of screw type, through the clamping piece 11.
    The invention is not limited to the particular variant embodiment of the clamping piece with clamping ramps 113.
    In another variant, the clamping ramps could be formed on the internal face 100 of the clamping piece 11 or could be formed on the outer face 100 of the locking piece 10. More generally in another variant, the clamping ramps 113 can be replaced by any equivalent means fulfilling the same progressive tightening function by relative displacement of the clamping part with respect to the blocking part 10.
    The clamping part 11 is not necessarily symmetrical, the central axis 11a not necessarily being an axis of symmetry of the part.
    The clamping part 11 is preferably a single piece which can be manufactured by any known means and for example by molding or by 3D printing.
    The material of the clamping piece 11 is of no importance for the invention. In a non-limiting and non-exhaustive manner, the clamping piece 11 can be made of plastic, and for example of polyamide 6. The clamping piece 11 can also be made of metal or a metal alloy, and for example a metal alloy, in particular of zinc, aluminum, magnesium and copper alloy, of the Zamak type.
    Preferably, the locking piece 10 can be chosen from a material different from that of the clamping piece, in order to reduce its cost price, knowing that once the fixing accessory has mounted the piece of
    BE2019 / 5481 blocking 10 is masked by the clamping piece 11 and is protected by the clamping piece 11, in particular from UV radiation from the sun.
    By way of example and without limitation of the invention, the blocking piece 10 can advantageously be made of plastic, and for example of polyamide 6 and the clamping piece 11 can be made of metal or a metal alloy, and in particular by Zamak.
    Figures 15 to 21 / t Figures 1 and 14 - Attaching a wire mesh panel 2 to a fence post 3 using the mounting accessory 1
    To fix a grid panel 2 to a fence post 3 by means of the fixing accessory 1, the procedure is for example as follows. Figure 15
    The mesh panel 2 is positioned relative to the fence post 3, the end warp wire 20 of the mesh panel 2 being positioned in the vertical groove 30 of the fence post 3.
    Figures 16
    The locking piece 10 is oriented and positioned in line with the groove 30 of the fence post 3, so that its internal face 101 with the housings 102A to 102D is oriented towards the bottom wall 30a of the groove 30, that its central axis 10a is oriented substantially perpendicular to the bottom wall 30a of the groove 30 and its width lw is oriented substantially horizontally. In this orientation, the two deformable clamping legs 103 are aligned vertically, being oriented respectively upwards and downwards.
    Figure 17
    The blocking piece 10 is introduced by hand into the groove 30 of the fence post 3 simply by moving it in translation in the direction of the bottom wall 30a of the groove 30, the blocking piece 10 passing easily between the two projections of restraint 30c (l10 <Emin).
    Figure 18
    The locking piece 10 is pivoted by hand on itself, in a vertical plane, around its central axis 10a oriented perpendicular to
    BE2019 / 5481 the bottom wall 30a, in one direction of rotation or the other, so as to bring, as a function of the direction of rotation of the piece 10, the opposite rounded edges 106A or the opposite rounded edges 106B of the tabs clamping 103 in contact with the connecting walls 30b. By continuing the rotation of the blocking piece 10 around the axis 10a, the clamping lugs 103 deform, which causes the length L10 of the blocking piece 10 to decrease, thereby allowing it to be force-fitted between the two connecting walls 30b of the groove 30. This rotation of the blocking piece 10 is carried out at an angle of approximately 90 °, until the length L10 of the piece 10 is aligned substantially horizontally, the clamping tabs 103 being substantially aligned horizontally.
    When the locking piece 10 is released in its position in FIG. 18, the clamping tabs 103 tend to return to their initial shape at rest and thus advantageously exert clamping forces on the connecting walls 30b of the groove 30 which immobilize the blocking piece 10 relative to the fence post 3, by elastic clamping of this blocking piece 10 in the groove 30 of the post 3. Figure 19
    The blocking piece 10, clamped between the two connecting walls 30b, is pushed by hand towards the bottom wall 30a of the groove 30, so as to introduce a portion of the end warp wire 20 into the housing of the piece of blocking 10 which is opposite this end warp wire 20, that is to say in the particular case of FIG. 19, the housing 102A or 102D. During this translation of the locking piece 10 towards the bottom wall 30, the clamping lugs 103 remain in contact with the connecting walls 30 of the groove 30 and thus maintain their tightening of the locking piece 10 in the groove 30, without obstructing the movement of the locking piece 10. Figure 20 and 21
    The clamping piece 11 is oriented and positioned by hand on the blocking piece 10, so that its central axis 11a is oriented substantially perpendicular to the bottom wall 30a of the groove 30, that
    BE2019 / 5481 its width lii is oriented substantially horizontally, and its internal face 111 is brought into plane contact against the external face 100 of the locking piece 10. The clamping ramps 113 of the clamping piece 10 are aligned substantially horizontally in being oriented respectively upwards and downwards, and the clamping face of their central part 113a is positioned in a plane situated between the retaining projections 30c and the locking piece 10.
    Figure 1 and 14
    The clamping piece 11 is pivoted by hand on itself, relative to the blocking piece 10, in a vertical plane and around its central axis 11a, in a direction of rotation R1 or in the other R2, at an angle of approximately 90 °, until the clamping ramps are aligned substantially horizontally (Figure 1). During this rotation and thanks to the clamping ramps 113, a progressive clamping of the clamping piece 11 is obtained between on the one hand the blocking piece 10, which is pushed into abutment against the bottom wall 30a of the groove 30 , and on the other hand the retaining projections 30c of the post 3 (Figure 14). The fixing accessory 1 is thus immobilized by clamping in all directions in the groove 30 of the post, and the end warp wire 20 of the grid panel 2 is blocked between the locking piece 10 and the bottom wall 30a of the throat 30 of the post 3.
    Once the clamping piece 11 has pivoted 90 ° about its axis 11a and its length L11 is aligned horizontally, the male fingerprint 114 anti-rotation of the clamping piece 11 is fitted into the female fingerprint 105 anti rotation of the locking piece 10 (FIG. 5), which allows the clamping piece 11 to be blocked in rotation relative to the locking piece 10 in both directions of rotation R1 and R2.
    During the installation of one or more mesh panels 2, the installer can firstly temporarily position all the locking pieces 10 in the grooves 30 and on the end chain wires 20 of the mesh panel (s) 2, then can check the correct positioning of the grid panel (s) 2, and if necessary correct the installation of a panel
    BE2019 / 5481 incorrectly positioned grid by removing the corresponding blocking piece (s) 10 and repositioning them once the positioning of the grid panel 2 has been corrected.
    Once the installer has ensured the correct positioning of the grid panel (s) 2, he can advantageously in a second step place all the clamping pieces 11 on the locking pieces 10, as previously described.
    All the above-mentioned laying operations can advantageously be carried out quickly and easily, in particular without using a specific tool for fitting the fixing accessories 1.
    Optionally, but without this being compulsory, it is also possible, once a fixing accessory 1 has been finally installed, to fix it to the fence post 3 by means of a screw or equivalent, penetrating into the bottom wall 30a of the groove 30 being passed through the clamping piece 11 and through the blocking piece 10 of the fixing accessory 1.
    In the particular variant embodiment, which has been described with reference to the appended figures, the two parts 10 and 11 of the fixing accessory 1 are separated from one another. This is not limitative of the invention. In another variant, the two parts 10 and 11 of the fixing accessory 1 could be mechanically connected together before and during their mounting in the groove of a fence post.
