Description

Technical Field

[0001] This application relates to the field of fencing, including wire mesh panels, particularly welded lattice type panels, which are assembled from spaced-apart vertical bars or spaced-apart vertical wires (commonly referred to as "warp bars" or "warp wires") and spaced-apart horizontal bars or spaced-apart horizontal wires (commonly referred to as "weft bars" or "weft wires"). In this field, the main objective of this application is to provide a novel fastening fitting that allows the wire mesh panels to be secured to fencing posts by positioning them within longitudinal grooves in the posts. Background Technology

[0002] There are known different types of fastening fittings that allow the mesh panels to be secured to the fence posts by positioning them in the longitudinal grooves of the fence posts.

[0003] In international patent application WO2010 / 121789, the fastening fitting includes a locking member with a rear surface for securing against the bottom wall of a longitudinal groove in the fence post. The locking member has at least one open seat groove extending in length to accommodate a portion of the end warp wire (vertical wire or vertical rod) of the mesh panel. This fastening fitting also necessarily includes a fixing element for securing the locking member in the fence post groove, such as a threaded rod with a self-breaking nut, designed to pass through the locking member and a pre-drilled through-hole in the bottom wall of the fence post groove. The mesh panel is secured to the fence post by at least one fastening fitting, a portion of the end warp wire of the mesh panel is positioned in the open seat groove of the locking member, and the locking member is secured against the bottom wall of the fence post groove, such that the end warp wire of the mesh panel is locked between the locking member and the bottom wall of the fence post groove.

[0004] In French patent application FR 2 908 439, the fastening fitting includes a rigid, elongated oval-shaped rotary locking element. Similar to the fastening fitting in the aforementioned international patent application WO2010 / 121789, this locking element includes a rear surface with at least one longitudinally extending groove capable of receiving a portion of the end warp wire (vertical wire or vertical rod) of the mesh panel. Unlike the scheme described in international patent application WO2010 / 121789, the profile constituting the fence post includes two longitudinal wings that are bent inward to form two longitudinal retaining protrusions facing the bottom wall of the longitudinal groove of the fence post. The installer can easily and manually pass the rotary locking element between the two longitudinal retaining protrusions to insert it with a gap into the groove of the fence post within the groove between the retaining protrusions and the bottom wall; the locking element is designed to pivot 90° within the groove of the fence post about an axis of rotation perpendicular to the bottom wall of the longitudinal groove (i.e., practically a horizontal axis of rotation). Once the swivel locking element is inserted into the groove of the fence post, particularly at a height advantageously selectable by the installer and pivoted 90°, the locking element is secured in the groove of the fence post by a fastening screw passing through the swivel locking element. The fixing element is supported on the bottom wall of the longitudinal groove and presses the swivel locking element against the two longitudinal retaining protrusions of the fence post.

[0005] Once inserted and pivoted 90°, the aforementioned rotary locking element is not fixed vertically until it is secured with the fastening screw. In particular, under its own weight, it may slide freely vertically within the groove of the fence post, forcing the installer to hold it by hand when installing the fastening screw, which unfavorably complicates the installation of the rotary locking element.

[0006] In French patent application FR 2 908 440, the fixing fitting is a locking member comprising two wings, one of which is elastically deformable. The locking member is introduced into the longitudinal groove of the fence post in the following manner: first, the rigid wing of the locking member is introduced into the groove, pressing against one of the longitudinal retaining protrusions; then, the locking member is pivoted to bring the other elastically deformable wing into contact with the other longitudinal retaining protrusion; subsequently, sufficient pressure is applied to the locking member to cause it to elastically bend into contact with the longitudinal retaining protrusion and be introduced into the longitudinal groove of the fence post. Similar to French patent application FR2 908 439, the locking member is then secured in the groove of the fence post by a fastening screw passing through the rotary locking member.

[0007] The locking element in French patent application FR 2 908 440 requires significant mechanical pressure to deform, making it difficult for fence installers to manually insert the locking element into the fence post recess. In practice, with this solution, installers have to use tools like pliers to force the locking element into the fence post recess.

[0008] Furthermore, during installation, fence installers may have to remove a portion of the fence to reinstall it, especially to better account for terrain undulations or slopes. Using the solution described in the aforementioned French patent application FR2 908 440, once the locking element is inserted into the groove, it is difficult to remove, thus posing a challenge to installers when the fence needs to be removed / reinstalled.

[0043] Figures 6 to 9 The image shows a fastening fitting A conforming to this application, which is suitable for securing the mesh panel 3 to the fence post 4.

[0044] The fence post 4 is constructed of a metal profile including two opposing longitudinal grooves 40 extending along the entire height (Z-axis) of the fence post. Each longitudinal groove 40 is defined by a bottom wall 40a, two longitudinal retaining protrusions 40c (which face the bottom wall 40a and extend along the entire height of the fence post 4), and two connecting walls 40b (which face each other and connect the two longitudinal retaining protrusions 40c to the bottom wall 40a respectively).

[0045] exist Figure 9In a specific embodiment, the mesh panel 3 is a rigid plate of the welded grating type, welded together from spaced-apart vertical bars (commonly referred to as "warp bars" or "warp wires") and spaced-apart horizontal bars 31 (commonly referred to as "weft bars" or "weft wires"). In this specific embodiment, the mesh panel 3 is a folded mesh panel type, with each vertical bar (warp wire) forming a V-shaped bend at the top. In other variations, each vertical bar (warp wire) may also form a V-shaped bend in the middle and / or at the bottom.

[0046] This application is not limited to folded screens, but extends to any type of known screen including spaced warp threads, and is particularly applicable to straight screens in which the vertical bars (warp threads) are straight along their entire length. The screen can also be of the "double-wire" type, meaning that such a screen may include multiple pairs of vertically spaced weft threads, each pair of weft threads fixed at the same height on both sides of the warp threads.

[0047] Fixed accessory A is included Figures 1 to 5 The rotary locking element 1 and the resilient rear fastening element 2 are shown separately in the image. Figures 6 to 8 ), and then the fastening element 2 is fixed to the rotary locking element 1.

[0048] Figures 1 to 5 Rotary locking element 1

[0049] Rotary locking element 1 is a flat, rigid component.

[0050] It has a central symmetry axis 1a ( Figure 3 and Figure 6 The central axis of symmetry corresponds to the (virtual) axis of rotation of the rotary locking element when it is installed in the fence post 4.

[0051] The rotary locking element 1 is not necessarily symmetrical, and the axis of rotation of the rotary locking element 1 is not necessarily a centrally symmetrical axis.

[0052] The rotary locking element 1 is more specifically oblong in shape, ( Figure 3 and Figure 4 It has a length L1 and width l1 measured in a plane (Y, Z) perpendicular to its central axis of symmetry 1a, and a thickness E1 measured parallel to its central axis of symmetry 1a.

[0053] The width l1 is less than the spacing E between the longitudinal retaining protrusions 40c of each longitudinal groove 40 of the fence post 4. Figure 9 ), while the length L1 is greater than the spacing E between the longitudinal retaining protrusions 40c of each longitudinal groove 40 of the fence post 4.

[0054] The rotary locking member 1 includes a rear surface 10 oriented towards the bottom wall 40a of the longitudinal groove 40 of the fence post 4. Figure 4), and the front surface 11 which is oriented in the opposite direction to the fence post 4.

[0055] The rear surface 10 includes a protrusion 12 and a post 13, which define a rear end plane P perpendicular to the central axis of symmetry 1a. Figure 4 ).

[0056] The protrusion 12 and the protrusion 13 recede relative to the rear end plane P to define the space forming the rear seat groove 14 with depth P1. Figure 4 The rear seat groove is straight and open, and in terms of length ( Figure 3 and Figure 4 It extends in the direction Y of the width of the rotary locking member 1 and over the entire width of the rotary locking member 1.

[0057] The rear seat groove 14 is sized to accommodate a portion of the end warp wire 30 of the mesh plate 3.

[0058] More specifically, to facilitate the rotation of the rotary locking member 1 into contact with the connecting wall 40b of the longitudinal groove 40 of the fence post, the two short sides of the rotary locking member 1, each with a width of l1, respectively form two curved edges 15. Figure 1 and Figure 3 These curved edges are rounded to form a convex curved support surface 15a radially opposite to the central axis of symmetry 1a of the rotary locking member 1 within the thickness of the rotary locking member 1.

[0059] The front surface 11 of the rotary locking member 1 also includes two front support surfaces 11a at two ends spaced apart along the length L1 of the rotary locking member 1. Figure 1 and Figure 2 ).

[0060] The two front support surfaces 11a are more specifically flat and coplanar in a plane perpendicular to the axis of rotation of the rotary locking member 1.

[0061] In another variation, the front surface 11 can be flat across its entire surface.

[0062] Rotary locking element 1 includes ( Figure 1 An inclined cylindrical eyelet 16, which is through and threaded, allows the pressure screw to pass through the rotary locking member 1.

[0063] The rotary locking element 1 is preferably a single piece and can be manufactured by any known method, such as by molding or by 3D printing.

[0064] The material of the rotary locking element 1 is not important to this application. In a non-limiting and non-exhaustive manner, the rotary locking element 1 may be made of metal or metal alloy, such as, in particular, a metal alloy of zinc, aluminum, magnesium and copper of the Zamak type. The rotary locking element 1 may also be made of plastic material, such as polyamide 6.

[0065] Figures 6 to 8 Rear fastening element 2

[0066] The rear fastening element 2 is fixed to the protrusion 12 of the rotary locking member 1 by any means, such as by adhesive, such that it protrudes completely from the rear surface 10 of the rotary locking member 1 in the lateral direction X (which also corresponds to the direction of the rotation axis of the rotary locking member 1) transverse to the rear surface.

[0067] The rear fastening element 2 is elastic and can be secured by pressure PR applied in the direction toward the rear surface 10 of the rotary locking element 1. Figure 7 And elastic deformation.

[0068] As will be more clearly shown below, the elasticity of the rear fastening element 2 must be sufficient to allow the fastening accessory A to elastically self-clamp between the two longitudinal retaining protrusions 40c and the bottom wall 40a of the longitudinal groove 40 of the fence post 4, so that the fastening accessory remains stationary in the vertical direction, preventing the fastening accessory A from sliding downward under its own weight after being installed in the fence post 4.

[0069] More specifically, the rear fastening element 2 is a foam pad with a maximum thickness of E2 in the resting state. Figure 7 and Figure 8 The thickness is elastically compressible under the pressure PR applied in the direction of the rear surface 10 of the rotary locking member 1.

[0070] The rear fastening element 2 does not necessarily protrude completely from the rear surface 10 of the rotary locking member 1 in the lateral direction X. In another variation, only a portion of the rear fastening element 2 may protrude from the rear surface 10 of the rotary locking member 1 in the lateral direction X, while another portion may retract relative to the rear end plane P and be accommodated in the rotary locking member.

[0071] In another variation, the fastening fitting A of this application may include a plurality of elastically deformable rear fastening elements.

[0072] Within the scope of this application, the rear fastening element is not necessarily an attachment element separate from and fixed to the rotary locking member 1. In another variation, the rear fastening element may also be an integral part of the rotary locking member 1, for example, it may be in the form of at least one flexible rear claw, forming only a single integral part integral with the rotary locking member 1. In another variation, the rear fastening element may also include a spring.

[0073] This application is not limited to implementing the elastic rear fastening element 2 in the form of a compressible pad, but such a compressible pad can be replaced by any equivalent rear fastening element 2, that is, the equivalent rear fastening element is elastically deformable by pressure PR applied in the direction of the rear surface of the rotary locking member, and can achieve the same function of elastically self-clamping the fixing accessory in the fence post to prevent the fixing accessory from sliding downward under its own weight after being installed in the fence post.

[0074] Figures 9 to 13 Fix the mesh panel 3 to the fence post 4.

[0075] To secure the mesh panel 3 to the fence post 4 using the fixing accessory A described above, for example, as follows.

[0076] Figure 9

[0077] Position the mesh panel 3 relative to the fence post 4, so that the end wire 30 of the mesh panel 3 is positioned in the vertical longitudinal groove 40 of the fence post 4, and is usually locked vertically by hanging the mesh panel 3 on the fence post 4 or supporting it on the ground.

[0078] Align and position the fixing accessory A with the longitudinal groove 40 of the fence post 4 (first rotation orientation) so that the rotation axis of the rotary locking member 1 is approximately perpendicular to the bottom wall 40a of the longitudinal groove 40, that is, the rotation axis is a horizontal axis, the length L1 of the rotary locking member 1 is approximately vertically oriented and the rear fastening element 2 is oriented toward the bottom wall 40a of the longitudinal groove 40.

[0079] The positioning of the fixing fitting A in the fence post 4 can be advantageously done at different heights.

[0080] Figure 10

[0081] The fixing fitting A is manually introduced into the longitudinal groove 40 of the fence post 4 as follows: the fixing fitting is horizontally translated toward the bottom wall 40a of the longitudinal groove 40, and the rear fastening element 2 is pressed against the bottom wall 40a to deform it sufficiently so that the two curved edges 15 and the front support surface 11a of the rotary locking element 1 are introduced into the longitudinal groove 40, and the rotary locking element 1 passes easily between the two longitudinal retaining protrusions 40c (l1 < E).

[0082] Figure 11

[0083] Maintain the pressure of the rear fastening element 2 against the bottom wall 40a, and manually move the rotary locking element 1 in the vertical plane, around the central symmetry axis 1a perpendicular to the bottom wall 40a, along the rotation direction R ( Figure 10The rotation (second rotation orientation) positions the two front support surfaces 11a of the rotary locking member against the longitudinal retaining protrusion 40c.

[0084] In this example, this rotation of the rotary locking element 1 is more specifically performed at an angle of approximately 90° until the length L1 of the rotary locking element 1 is roughly horizontally aligned.

[0085] In the second rotational position of the fixing accessory A, a portion of the end warp wire 30 of the mesh plate 3 is positioned in the rear seat groove 14 (vertical orientation) of the rotary locking member 1, and is horizontally locked between the rear seat groove 14 and the bottom wall 40a of the fence post 4.

[0086] Finally, Figure 11 In the second rotation position, release the fixed accessory A.

[0087] When the fixing accessory A is released, the rear fastening element 2 of the rotary locking member 1 tends to return to its initial resting shape due to its elasticity, and applies a fastening force to the bottom wall 40a of the fence post. The counterforce from the bottom wall 40a allows the front support surface 11a of the rotary locking member 1 to press tightly against the two longitudinal retaining protrusions 40c. Thus, the fixing accessory A is elastically self-clamped between the bottom wall 40a and the two longitudinal retaining protrusions 40c, keeping it vertically stationary. The elasticity of the rear fastening element 2 must be sufficient to prevent the fixing accessory A from sliding downwards under its own weight after being installed in the fence post 4.

[0088] Figure 12

[0089] Once the fixing accessory A is installed in the fence post 4, it is secured by a fastening screw or similar component that passes through a threaded through-hole 16 in the rotary locking member 1 and is tightened using a special tool (e.g., a bent wrench 17) to abut against the bottom wall 40a of the fence post 4. The fastening screw, by abutting against the bottom wall 40a of the fence post, allows for a stronger push of the fixing accessory A against the longitudinal retaining protrusion 40c, thus reinforcing the fastening of the fixing accessory A in the fence post.

[0090] When installing one or more mesh panels 3, the installer can first temporarily install all the fixing accessories A in the fence post 4 and on the end wire 30 of the mesh panel 3. Then, the installer can check whether the mesh panel 3 is well positioned. If necessary, the improperly positioned mesh panel can be corrected by removing the corresponding fixing accessories and repositioning them after the mesh panel 3 is properly positioned.

[0091] Once the installer confirms that the one or more mesh panels 3 are correctly positioned, it is advantageous to reinforce the fastening of the fastening fittings by tightening screws, as previously described.

[0092] Figure 13

[0093] exist Figure 13 In certain variations, in a manner that is optional rather than essential for this application, once the fixing fitting A is installed in the fence post and secured by screws or similar components, the cover plate 18 is preferably removably engaged on the front surface 11 of the rotary locking member 1, in particular to conceal the through hole 16 and the fastening screw.

[0094] When necessary, to prevent the theft of the fence panels, within the scope of this application, and in a manner known per se, each fixing accessory A may also be permanently secured by using a threaded rod with a self-breaking nut that passes through the bottom wall 40a of the fence post and through or into the fixing accessory A.
