Description

[0001] The invention relates to a fence fastening device for attaching mesh panels to fence posts, comprising a fence post, a support bracket, and a fastening screw. The support bracket has a through-hole for the fastening screw and can be fastened to the fence post by means of the fastening screw. Furthermore, the invention also relates to a support bracket for attaching two mesh panels to a fence post, the support bracket having a front side, a back side, and a through-hole for a fastening screw extending from the front side to the back side.

[0002] Fences made of mesh panels are widely used in both private and commercial areas to demarcate or fence off properties. The individual mesh panels, consisting of multiple vertical and horizontal bars, are available in various heights and widths. These types of mesh panels are often referred to as double-bar panels because the vertical bars are typically welded to several pairs of parallel horizontal bars. Due to their minimalist design, mesh panel fences blend into any environment. Their applications are diverse thanks to the various designs and manufacturing methods.

[0003] When erecting a fence, the individual mesh panels are each attached to the corresponding fence post. Fence posts commonly have several support trestles mounted lengthwise along the fence post at a distance from each other, onto which two mesh panels can be suspended. The individual support trestles are attached to the fence post using screws; for this purpose, blind rivets with a corresponding internal thread are first inserted into holes in the hollow fence post. To secure the mesh panels, one mounting plate per support trestle can be pressed against the outer vertical bars of the attached mesh panels using the screw. Alternatively, to using one mounting plate per support trestle, a cover strip extending the length of the fence post can be attached to the support trestles or the fence post using the screws.

[0004] Such a fence, in which the support blocks are attached by means of screws screwed into rivet nuts in the fence post, is known from EP 2 020 473 A2. According to this document, the installation of a cover strip on the fence post is to be simplified by providing a fixing slot in each of the edges of the U-shaped legs of the U-shaped support block facing away from the fence post. The fixing slots serve to accommodate corresponding sheet metal edges of the cover strip, so that the cover strip does not need to be screwed to the support blocks.

[0005] A slightly different way of attaching mesh panels to fence posts is known from DE 299 06 653 U1. This fence fastening also comprises a fence post, a support bracket and a fastening screw, whereby the support bracket has a through-hole for the fastening screw. Instead of a rivet, with this fence fastening a dowel is inserted through the through-hole in the support bracket into a corresponding hole in the fence post. Barbs are formed on the dowel which grip behind the wall of the fence post surrounding the hole in the fence post, so that a support bracket is pre-assembled on the fence post after the dowel is inserted. To ensure the support bracket is firmly in place, after the mesh panels have been hung on the support bracket, a fastening screw is screwed into the dowel, which spreads the dowel and presses it against the edge of the hole in the fence post.The support bracket and the dowel are designed as individual parts made of plastic in accordance with the teaching of DE 299 06 653 U1.

[0006] The present invention is based on the object of providing a fence fastening system as described above, which is particularly simple in design and allows for easy attachment of mesh panels to fence posts. Furthermore, a support bracket is also to be provided that can be used for fence fastening and easily attached to the fence post.

[0007] This problem is solved with the fence fastening system described above, having the features of patent claim 1, in that a hole collar with an internal thread is formed in the fence post, into which the fastening screw can be screwed. By forming the hole collar with an internal thread in the fence post, both the use of rivets and dowels can be dispensed with. This reduces the number of components required for the fence fastening, making the fence fastening particularly simple. Furthermore, the hole collar can be manufactured directly during the manufacture of the fence post, simplifying the installation of the mesh panels on the fence post for the customer, as they do not first have to attach rivets or dowels to the fence post.

[0008] As stated above, to secure the mesh panels, several support brackets are usually attached to a fence post at a distance from each other. According to the invention, the fence post is then provided with at least as many hole collars with internal threads as the number of support brackets to be attached to the fence post. However, the number of hole collars in the fence post can also be greater than the number of support brackets. The fence fastening according to the invention then consists of a corresponding fence post and several support brackets, as well as a number of fastening screws corresponding to the number of support brackets.

[0009] According to a preferred embodiment, the hole collars in the fence post are produced by flow drilling or as a punch thread. This allows for simple machine production of the fence posts with hole collars. The hole collar in the fence post preferably has a length that is significantly greater than the wall thickness of the fence post. This enables secure attachment of the support brackets to the fence post, as sufficient screw-in length can be provided for the fastening screw.

[0010] According to a further advantageous embodiment of the fence fastening according to the invention, the support bracket has at least one locking element on its rear side facing the fence post. Corresponding to the locking element, at least one opening for receiving the locking element is formed in the fence post. The provision of at least one locking element on the support bracket allows it to be easily pre-assembled on the fence post by inserting the locking element into the corresponding opening in the fence post.

[0011] The support bracket preferably has a plurality of locking elements, in particular three or four locking elements, with a plurality of openings correspondingly formed in the fence post for receiving a respective locking element. By providing a plurality of locking elements, the support bracket can be pre-assembled even more securely on the fence post before the fastening screw is screwed into the internal thread of the hole collar formed in the fence post. The plurality of locking elements are preferably arranged on the rear side of the support bracket such that the through-hole is located centrally between the locking elements.

[0012] The mesh panels are then attached to the support trestles attached to the fence post in the usual way: first, two mesh panels are hooked onto the support trestles. To secure the mesh panels, one mounting plate per support trestle can then be pressed against the attached mesh panels using the fastening screw. Alternatively, a cover strip can be attached to the support trestles, the length of which essentially corresponds to that of the fence post.

[0013] The aforementioned support bracket can be used particularly easily to attach two mesh panels to a fence post because the support bracket has at least one locking element on its back. The design of the at least one locking element on the support bracket allows it to be easily pre-assembled on the fence post by inserting the at least one locking element into a corresponding opening in the fence post. The support bracket is thus already held to the fence post before it is then securely fastened by screwing the fastening screw into the hole collar.

[0014] The support block preferably has a plurality of locking elements, for which purpose a plurality of openings are formed in the fence post, each of which accommodates a locking element. The plurality of locking elements, for example three or four locking elements, are arranged on the support block in such a way that it does not tilt or slip when the locking elements are inserted into the openings in the fence post. The locking elements are preferably positioned symmetrically to the longitudinal and / or transverse axis of the support block, in particular near the edges of the support block. The plurality of locking elements are preferably arranged on the rear of the support block in such a way that the insertion opening is located centrally between the locking elements.

[0015] According to a further preferred embodiment of the support frame, the through-hole on the front side of the support frame is surrounded by a recess for receiving the head of a fastening screw. This prevents the screw head from protruding beyond the front side of the support frame when the support frame is attached to the fence post using the fastening screw, so that the screw head does not interfere with the mesh panels' contact with the support frame.

[0016] The support frame is preferably H-shaped, with two legs protruding from the front and two legs protruding from the back. The legs protruding from the front serve to laterally support two vertical bars of two mesh panels, and the legs protruding from the back serve to laterally support the support frame against the fence post, preventing the support frame from slipping perpendicular to the longitudinal axis of the fence post.

[0017] The support frame is preferably made of plastic, especially polypropylene, so that it can be easily manufactured by machine, for example, by injection molding. The material of the support frame preferably contains a UV stabilizer to ensure colorfastness even after prolonged exposure to sunlight.

[0018] In detail, there are several possibilities for designing and developing the fence fastening and support frame according to the invention. Reference is made to the dependent claims as well as to the following description of a preferred embodiment in conjunction with the drawing. The drawing shows: Fig. 1 shows a section of a mesh fence with a fence fastening, Fig. 2 shows an exploded view of a fence fastening, Fig. 3 shows a sectional view of a fence post with a separate support bracket, Fig. 4 shows the fence post from the front, with a separate support bracket, Fig. 5 shows the fence post from the front, with a mounted support bracket, Fig. 6 shows a perspective view of a support bracket of the fence fastening, and Fig. 7 shows the support bracket according to Fig. 6 , from the front.

[0019] Fig. 1 shows a fence fastening 1 of a partially shown mesh fence, in which two mesh panels 2 are attached to a fence post 3. For this purpose, several support blocks 4 are arranged on the fence post 3, of which Fig. 1 The two upper ones are shown. The support blocks 4 are each attached to the fence post 3 with a fastening screw 5.

[0020] In addition, the two mesh panels 2 are fixed to the fence post 3 or to the support brackets 4 by mounting plates 6, in which the outer vertical bars 21 of the two suspended mesh panels 2 are pressed against a support bracket 4 by a mounting plate 6 using the fastening screw 5. The fastening screws 5 thus serve both to fix the mesh panels 2 to the support brackets 4 using the mounting plates 6 and to fix the support brackets 4 to the fence post 3.

[0021] Fig. 2 shows an exploded view of a fence fastening 1 consisting of a fence post 3, a support bracket 4 and a fastening screw 5 and Fig. 3 a representation of the fence post 3 in cross section, with a support block 4 arranged next to it, not yet attached to the fence post 3. As can be seen from these figures and the separate representation of the support block 4 in the Figs. 6 and 7As can be seen, the support frame 4 has a front side 41, a back side 42, and a through-opening 43 that extends from the front side 41 through the support frame 4 to the back side 42. The through-opening 43 serves to accommodate a fastening screw 5, with which the support frame 4 can be fastened to the fence post 3. When the support frame 4 is mounted on the fence post 3, the front side 41 serves to support the bars 21 of the mesh mats 2, and the back side 42 serves to support the support frame 4 on the fence post 3.

[0022] For fastening the support bracket 4 to the fence post 3, a hole collar 31 with an internal thread 32 is formed in the fence post 3, into which the fastening screw 5 can be screwed with its external thread 51. The hole collar 31, which is preferably produced in the hollow fence post 3 by flow drilling or as a punch thread, is shown in the sectional view of the fence post 3 according to Fig. 3visible. It can also be seen there that the hole collar 31 has a length L which is significantly greater than the wall thickness d of the fence post 3. Preferably, the length L of the hole collar 31 is a multiple of the wall thickness d of the fence post 3, in particular at least 3 times. This ensures secure fastening of the support bracket 4 to the fence post 3, since a sufficient screw-in length is available for the fastening screw 5. Due to the formation of the hole collar 31 in the fence post 3, it is not necessary to fasten blind rivets in openings in the fence post 3 in an additional work step in order to be able to fasten the fastening screws 5 in the fence post 3.

[0023] From the front view of the support bracket 4 according to the Fig. 5 and 7It can be seen that the through-hole 43 on the front side 41 of the support frame 4 is surrounded by a recess 44. The recess 44 serves to accommodate the screw head 52 of the fastening screw 5, so that the screw head 52 does not protrude beyond the front side 41 of the support frame 4 when the support frame 4 is fastened to the fence post 3 using the fastening screw 5. As a result, the screw head 52 does not hinder the attachment of the bars 21 of the mesh panels 2 to the support frame 4.

[0024] So that the support frame 4 can already be attached to the fence post 3 before the fastening screw 5 is screwed into the hole collar 31, the support frame 4 has a plurality of locking elements 45 on its rear side 42 facing the fence post 3, which can be inserted into corresponding openings 33 in the fence post 3. The support frame 4 can thus be easily pre-assembled on the fence post 3 before it is fixed to the fence post 3 by means of the fastening screw 5 after the mesh panels 2 have been hung in. The locking elements 45 can, for example, be designed as locking hooks, the locking lug of which engages behind the edge of the opening 33 in the fence post 3.

[0025] The four locking elements 45 in this case are arranged on the support frame 4 in such a way that it does not tilt or slip when the locking elements 45 are inserted into the openings 33 in the fence post 3. For this purpose, the locking elements 45 are arranged symmetrically to the longitudinal and transverse axes of the support frame 4. Furthermore, the locking elements 45 are arranged on the rear side 42 of the support frame 4 in such a way that the through-opening 43 is located centrally between the locking elements 45 (see Fig. 6 ).

[0026] Correspondingly, the openings 33 in the fence post 3, into which the locking elements 45 are inserted, are arranged symmetrically to the longitudinal and transverse axes of the support bracket 4, wherein the hole collar 31 is located centrally between the openings 33, corresponding to the through-opening 43 in the support bracket 4 (cf. Fig. 4). In the illustrated embodiment, the four openings 33 form the corners of an imaginary rectangle, in the center of which the hole collar 31 is arranged.

[0027] As can be seen particularly from the perspective view of the support bracket 4 according to Fig. 6As can be seen, the support frame 4 is H-shaped. The support frame 4 has two legs 46 protruding from the front side 41 and two legs 47 protruding from the rear side 42. The legs 46 protruding from the front side 41 each serve to laterally support the outer vertical bar 21 of a mesh panel 2 on the support frame 4, so that the mesh panels 2 can be easily positioned. In addition, the support frame 4 has a nose 48 on the upper and lower edge of each of the legs 46 protruding from the front side 41, wherein when the support frame 4 is assembled, the upper nose 48 engages between the two parallel horizontal bars 22 of the mesh panels 2. As a result, the mesh panels 2 have a defined distance from the fence post 3.The legs 47 protruding from the rear side 42 serve to laterally support the support bracket 4 against the fence post 3, so that the support bracket 4 cannot slip perpendicular to the longitudinal extension of the fence post 3. The lateral legs 47 thus also serve as protection for the locking elements 45, preventing them from being damaged if a lateral force acts on the support brackets 4 during assembly of the support brackets 4 or the mesh mats 2.
