Description

[0001] The present invention relates to a fastening element for attachment to a double-wire fence, wherein the fastening element has at least two teeth on its underside for insertion into the gaps between horizontal double wires of a double-wire fence and a recess on its front side, the recess being a continuous recess extending from the top to the underside of the fastening element for insertion of the fastening element onto a vertical wire of a double-wire fence, characterized in that the teeth are arranged centrally and perpendicular to the recess on the underside of the fastening element. The invention further relates to a double-wire fence comprising a fastening element according to the present invention. The invention also relates to the use of the fastening element according to the present invention for attaching objects, in particular a privacy screen, to a double-wire fence.

[0002] Double-wire fences are produced worldwide in large quantities and are characterized by their durability and weather resistance. They feature double horizontal wires and single vertical wires. Double-wire fences are primarily used to separate or enclose properties.

[0003] Double wire mesh fences are often retrofitted with privacy screens to create an opaque boundary. In particular, PVC privacy strips are woven between the vertical wires of the double wire mesh fences.

[0004] Attaching conventional privacy screens, for example made of wood or metal, to double wire mesh fences is costly and labor-intensive due to insufficient fastening elements.

[0005] German patent DE 20 2014 100 913 U1 describes a connector for attaching building components, such as privacy screens, to double-wire fences. The connectors are screwed between two vertical wires of a mesh of the double-wire fence.

[0006] However, these connectors have the disadvantage that they can shift vertically, especially with heavy conventional privacy screen elements.

[0007] Furthermore, the mesh width between the two vertical bars is limited by the connector.

[0008] Furthermore, attaching these connectors involves a great deal of work, as it must be ensured that each connector is mounted at the correct height so that the privacy screen element is properly attached to the double wire fence.

[0009] DE 10 2014 111 631 B4 relates to a method for assembling a gabion comprising mesh panels defining a filling space, wherein the mesh panels each comprise at least two spaced-apart double bars forming a free space and at least two spaced-apart single bars, wherein the single bars run perpendicular to the double bars and wherein at least one connector is provided for connecting each pair of adjacent mesh panels, which has at least one base part with at least one holding area.

[0010] DE 10 2019 134 964 B3 refers to a mounting bracket for double wire mesh fences.

[0011] DE 10 2016 003 211 A1 refers to a flexible metal rod fence screw-in bracket with screw lock, for flexible hanging in individual wire mesh panels of rod fences of various types, for fastening and mounting common objects for daily private and commercial use.

[0012] The invention is based on the objective of easily attaching privacy screen elements to a double wire fence.

[0013] The aforementioned problems are solved with a fastening element for attachment to a double wire fence, wherein the fastening element has at least two teeth on the underside for insertion into the gaps between horizontal double wires of a double wire fence and a recess on the front, wherein the recess is a continuous recess extending from the top to the underside of the fastening element for insertion of the fastening element onto a vertical wire of a double wire fence, characterized in that the teeth are arranged centrally and perpendicular to the recess on the underside of the fastening element.

[0014] Likewise, the problem is solved by a double wire mesh fence according to claim 5 and by the use according to claim 8.

[0015] The fastening element according to the invention is suitable for attachment to a double wire fence. However, the fastening element according to the invention can also be attached to a single wire fence.

[0016] Double-wire and single-wire fences are available in various designs. The diameter of the individual wires in these fences is typically 4 to 8 mm, or 4 mm, 5 mm, 6 mm, or 8 mm. The individual wires are usually made of metal or steel with a powder coating. The metal may also be galvanized. The powder coating is typically applied and cured after the individual wires are joined together, for example, by welding, to form the fence panel. Consequently, the diameter of the wires in a fence panel can vary. The tolerance is typically + / - 0.2 mm. The vertical wires of a double-wire fence can have a diameter of 4 to 6.5 mm, preferably 5 to 5.5 mm and / or 6 to 6.5 mm. The rods of the horizontal double bars can each have a diameter of 5 to 8.5 mm, preferably 6 to 6.5 mm and / or 8 to 8.5 mm.

[0017] The diameter of the individual wires in a double-wire fence is usually specified with a three-digit number, where the first and last digits describe the diameter of the respective horizontal double wires, and the middle digit describes the diameter in millimeters of the vertical wire located between the two horizontal wires. Accordingly, a 6 / 5 / 6 double-wire fence has horizontal double wires with a diameter of 6 mm each and one vertical wire with a diameter of 5 mm. As described above, the tolerance for the diameters is typically + / - 0.2 mm.

[0018] For example, double wire mesh fences are available in the following configurations: 4 / 4 / 4, 4 / 5 / 4, 4 / 6 / 4, 4 / 8 / 4, 5 / 4 / 5, 5 / 5 / 5, 5 / 6 / 5, 5 / 8 / 5, 6 / 4 / 6, 6 / 5 / 6, 6 / 6 / 6, 6 / 8 / 6, 8 / 4 / 8, 8 / 5 / 8, 8 / 6 / 8, 8 / 8 / 8. The fastening element according to the invention can be used for all the aforementioned double wire mesh fences. In particular, the fastening element according to the invention can be used for 5 / 5 / 5, 6 / 5 / 6 and 8 / 6 / 8 double wire mesh fences.

[0019] Single-wire mesh fences usually have wires of a specific diameter, for example 4 mm, 5 mm, 6 mm, or 8 mm. Accordingly, the diameter of the horizontal and vertical wires is the same.

[0020] The individual wires of mesh fences are typically welded together, with a weld depth of approximately 2 mm. Accordingly, the overall diameter of a double-wire fence at the weld point of the three wires can be smaller than the overall diameter of the individual, unwelded wires. For example, the overall diameter at the weld point of a 6 / 5 / 6 double-wire fence can be 13 mm with a weld depth of 2 mm.

[0021] The area between the horizontal and vertical wires is called a mesh. In a double-wire fence, a mesh is defined by two vertical, parallel wires and two horizontal, parallel double wires.

[0022] The spacing between the vertical wires of a fence panel is usually constant. The distance between the centers of the vertical wires of a double-wire fence panel is generally 50 mm, and the distance between the centers of the horizontal double wires is generally 200 mm (mesh size). However, the fastening element according to the invention can be attached to fence panels with any mesh size.

[0023] A privacy screen element can be attached to a mesh fence or a double-wire fence using the fastening element. The privacy screen element can be made of wood, metal, or plastic. Preferably, a privacy screen element is made of wood, such as a wooden board. However, the fastening element according to the invention can be used to attach any object to a mesh fence, such as a double-wire fence.

[0024] The fastening element according to the invention is used for attachment to a double wire fence. The fastening element has at least two teeth on its underside for insertion into the gaps between horizontal double wires of a double wire fence and a recess on its front side, wherein the recess is a continuous depression extending from the top to the underside of the fastening element for insertion of the fastening element onto a vertical wire of a double wire fence.

[0025] The recess is preferably designed so that the fastening element can be attached to a vertical rod of a double wire fence, so that the vertical rod of a double wire fence fits into the recess and the teeth each fit into a gap of horizontal double rods, the meshes separated by the vertical rod.

[0026] The fastener can be inserted into a vertical bar using the recess, with the teeth positioned between the gaps of the horizontal double bars. Thus, after the fastener is mounted to a double-wire fence, the vertical bar of the fence is positioned in the recess.

[0027] The fastening element is designed to fit into the gap between two double wires described above, with the teeth fitting into the corresponding recess of the vertical wire mesh fence. It is advantageous if the width of the fastening element is chosen to match the width of the double wires or be narrower. This allows the privacy screen to fit flush against the double wire mesh fence without any gaps. The double wires are the horizontal wires of a double wire mesh fence.

[0028] The fastening element can (A) have a length of 30 to 50 mm, preferably 35 to 45 mm, particularly preferably 39 to 43 mm, most preferably 40 to 42 mm, (B) have a width of 14 to 25 mm, preferably 16 to 22 mm, particularly preferably 18 to 20 mm, most preferably 19 to 21 mm, (C) have a height without teeth of 10 to 40 mm, preferably 15 to 30 mm, particularly preferably 18 to 22 mm, most preferably 20 to 21 mm, and / or (D) have a width corresponding to the width of the horizontal double wires of a double wire mesh fence.

[0029] The teeth of the fastening element can (A) each have a length of 10 to 25 mm, preferably 12 to 20 mm, particularly preferably 14 to 18 mm, most preferably 15 to 16 mm, (B) each have a width of 1 to 7 mm, preferably 2.5 to 6 mm, particularly preferably 3 to 5 mm, most preferably 2.5 to 3.5 mm, (C) each have a height of 4 to 15 mm, preferably 5 to 12 mm, particularly preferably 6 to 10 mm, most preferably 7 to 9 mm, (D) each have a height corresponding to the diameter of one of the double wires of a double wire fence, (E) each have a width corresponding to the width of the gaps between horizontal double wires of a double wire fence, and / or (F) each have a distance from each other of 6 to 15 mm, preferably 7 to 12 mm, particularly preferably 7.5 to 10 mm, preferably 8 to 9.5 mm.

[0030] The teeth are positioned centrally and perpendicular to the recess or indentation on the underside of the fastening element. "Perpendicular to the recess or indentation" means that the longitudinal axis of the two teeth and the longitudinal axis of the indentation should be orthogonal.

[0031] The teeth should extend centrally on the underside of the fastening element and parallel to the longitudinal axis of the fastening element.

[0032] The fastener can be made from any material. Possible materials include wood, plastic, or metal. Suitable plastics include thermoplastics, thermosets, and elastomers. Elastomers have the advantage that the fastener can adapt to the structure or shape of the mesh fence or privacy screen. Thermoplastics are particularly suitable for manufacturing fasteners by extrusion. Thermosets are especially suitable for fasteners because they are particularly robust and can therefore support even heavy privacy screens. Suitable plastics include polyvinyl chloride (PVC), polyester, melamine resins, silicone resins, polyurethanes, polyamides, polypropylene, acrylic resins, polycarbonates, polyphenylene oxide, polystyrene, polytetrafluoroethylene, and polyethylene.

[0033] The fastener can be made of a thermoplastic material. The fastener can be coated.

[0034] The teeth can be curved towards the rear and at least partially enclose one of the horizontal double wires with the curve. Additionally, there can be two recesses on the underside of the fastening element for the respective horizontal double wires of a double-wire fence. Accordingly, a first recess is located parallel to the teeth, or rather to the longitudinal axis of the teeth, on the underside of the fastening element towards the front, and a second recess is located parallel to the teeth, or rather to the longitudinal axis of the teeth, on the underside of the fastening element towards the rear. These recesses may be interrupted by the recess for the vertical wires.

[0035] The recess on the front side can have a depth corresponding to half the width of the fastener and half the diameter of the vertical bar of a double-wire fence, and / or the recess can have a depth of 9 to 16 mm, preferably 10 to 14 mm, particularly preferably 11 to 14 mm, most preferably 12 to 13.5 mm. The depth can be measured from the top or bottom of the fastener. The depth is the maximum depth of the recess when viewed from the top or bottom. The maximum depth takes into account that the vertical bar of a fence is round and the recess is also rounded when viewed from the top or bottom. The depth when viewed from the top or bottom is, for example, the Fig. 2 can be seen.

[0036] Viewed from the front, the fastener has a recess that extends continuously and perpendicularly to its longitudinal axis. This recess is positioned centrally. Viewed from the underside, a cutout is visible, extending from the center of the underside to one of the fastener's outer edges. Thus, the recess forms a cutout on both the top and bottom surfaces of the fastener, extending perpendicularly to the fastener's longitudinal axis from the center point of the top or bottom surface to the outer edge, towards the front.

[0037] The recess can narrow from top to bottom and / or the opening from outside to inside. In this case, the narrowing should have a smaller diameter or width at its narrowest point than the vertical bar of the mesh fence, so that the vertical bar can be forced into its final position in the fastener with a specific force. The recess should have a central area, relative to the top or bottom of the fastener, with a larger diameter or width than the narrowing; the inner diameter of this area should preferably be equal to or 1 to 10% larger than the outer diameter of the vertical bar.

[0038] The fastening element can have at least two bores. The bores preferably extend centrally through the left and right halves of the front and back of the fastening element, respectively. Particularly preferably, each bore additionally includes a countersink for a fastening element, e.g., a screw. The respective bores on the front and back of the fastening element particularly preferably each have a countersink for a fastening element, in particular a screw head.

[0039] In addition, a double wire mesh fence is provided, which includes a fastening element according to the invention.

[0040] The fastening element according to the invention is used for attaching objects, in particular a privacy screen, to a double wire fence.

[0042] Fig. Figure 1 shows a fastening element (100) according to the invention in a three-dimensional perspective. A recess (104) is arranged on the front of the fastening element (100). The recess (104) extends centrally from top to bottom on the front of the fastening element (100). Also on the front are two bores (105) for fastening materials, such as screws, which allow privacy screens to be attached. Two teeth (102, 103) are located on the underside of the fastening element (100). The back of the fastening element (100) is not visible in this figure.

[0043] Fig. Figure 2 shows a projection (200) of the fastening element according to the invention. The projection (200) shows the front (201), back (202), top (203), bottom (204), left side (205), and right side (206).

[0044] On the front side (201) is the recess (104) and two boreholes (105). On the back side (202), the boreholes (105) extend continuously from the front side (201) through the back side (202). The two teeth (102, 103) are arranged orthogonally to the longitudinal axis of the recess. A gap is present between the two teeth (102, 103). The distance (213) between the teeth (102, 103) is greater than the width (218) of the recess. The width (218) of the recess can be the diameter of the vertical bar of the mesh fence. The width (218) of the recess can be 4 to 6.5 mm, preferably 5 to 5.5 mm and / or 6 to 6.5 mm. The distance (213) between the teeth (102, 103) can be 4.5 to 10 mm, preferably 5.5 to 9 mm and / or 6.5 to 8 mm. The distance (213) between the teeth (102, 103), which is greater than the width (218) of the recess, has the advantage that the fastening element can be easily attached to the mesh fence.A weld is typically located where the fastener is attached to the mesh fence. The distance (213) between the teeth (102, 103) creates a gap that provides space for the weld. The height (211) of the fastener (100) consists of the height (214) without teeth and the height (215) of the teeth.

[0045] Fig. Figure 3 shows a projection (300) of the fastening element according to the invention with two curved teeth (102, 103). The projection (300) shows the front (301), back (302), top (303), bottom (304), left side (305), and right side (306).

[0046] The teeth (102, 103) are curved towards the rear (302), as can be seen from the left side (305) and the right side (306). Accordingly, it is possible to insert the fastening element (100) with two curved teeth (102, 103) at an angle into the gaps between the horizontal double wires and, with a twisting motion towards the front (301), hook the fastening element into the double wire fence so that the vertical wire of the double panel sinks into the recess (314). This has the advantage that the fastening element (100) is fixed to the double wire fence and cannot be lifted out in an upward motion without twisting. In particular, it is then no longer possible to remove the fastening element (100) with an attached privacy screen element from the double wire fence.

[0047] To allow the horizontal double bars to rest against the fastening element (100) with the curved teeth (102, 103), recesses (310, 311) for the horizontal double bars are arranged on the back side (304) of the fastening element (100) on both sides separated by the teeth. The recesses have a rounded shape, each corresponding to one of the double bars. The teeth also have a rounded surface. Accordingly, the fastening element (100) with the curved teeth (102, 103) has a rounded surface on the teeth and on the underside (304) of the fastening element (100) so that the respective horizontal double bars fit into it. For example, a fastening element (100) with the curved teeth (102, 103) can be manufactured and finally drilled from the right side (306) along and through the left side (305), with the respective holes corresponding to the diameter of one of the horizontal double bars.The hole should be centered so that the fastening element (100) fits into the gap between the two horizontal double bars.

[0048] The Fig. Figure 3b shows the attachment of a fastening element (100) according to the invention, having two curved teeth (102, 103), wherein the fastening element (100) is inserted at an angle into the gaps of the horizontal double bars and is brought into its final position by a rotation (marked with an arrow). The front side (303) of the fastening element (100) faces the vertical bar so that the vertical bar can be inserted into the recess (104).

[0049] The Fig. Figure 4 shows a double-wire fence (401) with two fastening elements (100) according to the invention. The double-wire fence (401) comprises vertical wires (402) and horizontal double wires (403). The vertical wires (402) and the horizontal double wires (403) form a mesh (404). As can be seen in this figure, the fastening elements (100) are mounted parallel to the horizontal double wires (403), so that the fastening elements (100) can always be mounted at a constant height. This allows for easy installation of the fastening elements (100) and facilitates the attachment of privacy screens.

[0050] The Fig. Figure 5 shows a section of a double-wire fence (401) in which a fastening element (100) is attached. The vertical wire (402) is inserted into the recess (104), which has a rounded shape (marked with dashed lines). The recess (104) is designed such that the vertical wire (402) is centered and can be inserted (501) centrally on the top surface (203) by the fastening element (100). The teeth (502, 503) are inserted into the respective gaps of the horizontal double wires (403) (marked with dashed lines).

[0051] The Fig. Figure 6 shows a double-wire fence (401) with four fastening elements (100) according to the invention, which were used to attach a privacy screen element (601). The privacy screen element (601) is connected to each fastening element (100) by two screws (602). The fastening elements (100) sit on the horizontal double wires (403), so that the load-bearing capacity of the privacy screen element (601) is transferred to the horizontal double wires (403). This prevents vertical displacement of the fastening elements (100), especially under heavy loads.

[0052] The Fig. Figures 7a to 7c each show a section of a double wire mesh fence (401) with a fastening element (100) from different perspectives. Fig. Figure 7a is a view from below, where the fastening element (100) does not project beyond the width (702) of the horizontal double bars. The teeth (102, 103) are positioned in the gaps (701) between the horizontal double bars (403). Accordingly, one tooth in the gap (701) is located to the left of the vertical bar (402) and one tooth in the gap (701) is located to the right of the vertical bar (402). The gap between the teeth is larger than the diameter of the vertical bar (402).

[0053] Fig. Figure 7b is a top view, where the width (212) of the fastening element (100) is equal to the width (702) of the horizontal double bars. Fig. Figure 7c shows the front (201) of the fastening element (100). The two teeth (102, 103) are arranged in the gap (701) between the horizontal double bars (403) (marked with dashed lines).

[0054] The Fig. Figure 8 shows a fastening element (100) with recesses (801) for a fastener, such as a screw. Accordingly, a screw can be used to fasten, for example, privacy screen elements, and the screw countersinks in the recess. This allows a privacy screen, which is attached to the opposite side by means of another fastening element (100), to be attached to the double-wire fence (401) without a gap or space. In the illustration, the recesses (801) for a fastener are visible on the front (201) of the fastening element (100). However, it is particularly preferred that the bores (105) on the front (201) as well as on the back (202) have recesses (801) for a fastener. Accordingly, a privacy screen element (601) can be mounted from both sides and a screw head can be countersunk.

[0055] The Fig. Figure 9 shows a fastening element (100) wherein the recess (901) narrows from the outside to the inside. In other words, the recess (901) narrows from top to bottom. The end of the recess (902) is rounded and has a diameter corresponding to the diameter of the respective vertical rod (402). The diameter of this rounding (902) for the respective vertical rod (402) can be 4 to 6.5 mm, preferably 5 to 5.5 mm and / or 6 to 6.5 mm. The diameter of the rounding (902) means that a rod of this diameter fits into the rounding (902) or that a bore is present which has been drilled from the top (203) to the bottom (204) centered with a drill of this diameter. Accordingly, the recess of a fastening element (100) can be produced by drilling a bore centered from the top (203) to the bottom (204) and the area orMaterial is removed between the bore and the front (201).

[0056] The Fig. Figure 10 shows the front face (201) of a fastening element (100). Line A represents the longitudinal axis of the fastening element (100). Line B represents the longitudinal axis of the two teeth (102, 103). Line C represents the longitudinal axis of the recess (104).
