Description

The invention relates to a fence with fence posts and fence mats, the fence mat consisting of lattice bars arranged vertically and horizontally to the ground and connected at crossing points, the fence mat being fastened or capable of being fastened to the fence post by means of holders, the holders having a base element which, by means of a a fastening element engaging in a receiving opening of the fence post is fastened or can be fastened to the fence post, the base element having parallel webs which on the one hand form support areas for horizontally running bars of the fence mat, the webs engaging behind vertical bars of the fence mat, and a securing element which covers the webs or at least covers the area between the bars and fixes the bars of the fence mat to the base element.

Such fences and in particular their base elements, which can be fastened or attached to the fence post for holding the fence panels, are known in the prior art and are extremely popular.

It is common in a solution known and widely used in the prior art to fix the base element to the fence post by means of a rivet connection projecting into the fence post.

This usually requires the use of special tools.

When assembling such a fence known in the prior art, the first step is to fasten the base element to the fence post, for example by riveting. After this attachment has taken place, a fence mat with the horizontally running lattice bars can be hung on corresponding support areas, which are formed on the base element by parallel webs. Then, in a further work step, a flat bar made of metal is often screwed into the rivet, which fixes the base element to the fence post, thus fixing the fence mat.

Fastening the fence panels to corresponding fence posts in this way is extremely time-consuming and often requires the use of special tools, particularly for fastening the base elements to corresponding recesses or perforations in the fence post, and requires a large number of parts to be carried along and stored.

Due to the state of the art mentioned at the outset, the object of the present invention is to create a fence of the type mentioned at the outset, in which the assembly time is significantly reduced, which can be carried out particularly easily even by inexperienced people without the help and stockpiling of special tools, which only has an extremely small number of parts to be used, which enables the fence panels to be securely and permanently fixed to corresponding fence posts.

To solve this problem, the invention proposes that the fastening element be formed by fastening areas that protrude from the base element and can be inserted or inserted into the receiving opening of the fence post and spread or can be spread open, with at least one fastening area being designed like a hook at or near a free end area and in the The fixing layer inserted into the receiving opening engages behind the edge of a perforation forming the receiving opening and fixes the base element in this position on the fence post, with the securing element having a protruding web which engages in the securing areas or reaches through them and thereby spreads the securing areas so that the securing element on the one hand The rod of the fence panel is fixed to the base element and on the other hand the base element is fixed to the fence post.

In such a solution according to the invention, the base element is first fixed to a hole in the fence post that forms the receiving opening, similar to the solutions known in the prior art. However, this fixation takes place by manually inserting the fastening areas of the base element into the perforation, without the need for a special tool, such as a riveting device. After the fastening areas of the base element have been pushed or pressed into the perforation of the fence post, they can reach behind the perforation and, if necessary, spread them open automatically, so that the base element can be attached to the through a perforation formed receiving opening of the fence post is attached. Then, in a manner known per se, a fence mat can be placed or hung on the support areas, which are formed by parallel webs of the base element. To fix the bars of the fence mat, a securing element is then inserted into the base element, which on the one hand fixes the bars of the fence mat on the base element and on the other hand the base element on the fence post. The base element is fixed to the fence post by means of the securing element in this way, that the securing element prevents the fastening areas of the base element from splaying into a loose position, that is to say in a position in which the fastening element could be removed again from the receiving opening of the fence post. The securing element thus serves on the one hand to fix the lattice bars and thus the respective fence mat to the base element and on the other hand to effectively prevent undesired loosening or removal of the base element from the perforation of the fence post forming the receiving opening.

Such a base element according to the invention, together with the safety element, can be installed at any time, even by inexperienced users, in a very short time in order to erect a corresponding fence, with the installer only having to store and keep a small number of different parts in stock and thus be able to install a fence in a very short time which the fence mats are held securely and permanently on the fence post in comparison to the solutions known in the prior art, with a significantly reduced assembly time.

It can particularly preferably be provided that the safety element is approximately T-shaped in cross section, with the vertical part of the T-shape forming the protruding web and the horizontal part of the T-shape forming the bar of a fence mat or one bar of two adjacent ones Fence mats fixed to the base element.

In particular, the formation of a T-shape enables insertion into the base element on the one hand and secure covering of the suspended or inserted bars of the fence mat on the other.

The horizontal part of the T-shape has a length that is sufficient to cover the suspended or inserted bars of the fence mat in relation to the base part and to prevent them from being removed from the base element. On the other hand, the vertical part of the T-shape has a length that is suitable for being arranged between the opposing fastening areas of the base element in the intended assembly position, i.e. in the position in which the securing element is fixed to the base element and secures the fence mat against removal and to fix them in the spread position. In this position, removal of the base element from the fence post is prevented, since the spread fastening areas engage behind the perforation of the fence post forming the receiving opening and thus fix the base element to the fence post.

The vertical part of the T-shape of the securing element thus effectively prevents the fastening areas from being shifted into a loose position, ie a position in which the base element can be removed from the receiving opening forming the perforation and removed.

In addition, it can particularly preferably be provided that the protruding web and the fastening areas of the base element have friction-increasing means or latching elements at least in their contact area, which fix the securing element on the fastening area in the fixing position of the protruding web inserted into the base element.

The arrangement of such friction-increasing means or latching elements according to the invention makes it significantly more difficult to remove the securing element from the base element. Accidental loosening or removal of the securing element from the base element is effectively prevented, for example, by vibrations or similar movements by the friction-increasing means or latching element.

In addition, it can particularly preferably be provided that feed aids, for example insertion bevels, are formed on the free ends of the fastening areas.

Insertion of the base element into the respective perforation, which forms the receiving opening of the fence post, is made significantly easier by means of such insertion bevels arranged at the free ends of the fastening regions.

Provision can also be made particularly preferably for the hook-like end region to be formed by a projection or a hook contour, with the projection or contour pivoting automatically into the fixing position after insertion into the perforation of the fence post and the desired position of the base element has been reached.

Such hook-like end regions according to the invention allow the layer inserted into the perforation, which forms the receiving opening of the fence post, to remain particularly secure on the fence post. After the fastening areas are inserted into the perforation and pivot slightly towards each other due to the contact of the insertion bevels with the reveal of the hole, they can pivot back independently after reaching the target position into the original position in which the hook-like end area engages behind the wall of the fence post and there stuck. It is thus only possible to remove the inserted base element if the fastening areas are moved towards one another again.

This results in a particularly secure and stable hold of the base element on the fence post or on the perforation of the fence post forming the receiving opening.

In a manner known per se, provision can be made particularly preferably for two fence mats to be fastened or fastened to the base element in a mutually aligned position.

A solution according to the invention can thus be used both for fastening a single fence panel and for fastening two fence panels aligned with one another.

It can also be particularly preferred that both fastening areas are hook-like at or near a free end area and in the fixing layer inserted into the receiving opening engage behind the edge of the perforation forming the receiving opening adjacent to the fastening area.

The formation of hook-like end regions on both sides makes it even more difficult to remove a base element that is in the intended assembly position, that is to say plugged in, and provides an even more secure hold.

Provision can also be made particularly preferably for the horizontal part of the T-shape of the securing element to have a perforation which opens into a recess formed on the vertical part (web), with a fastening means reaching through the perforation and entering the recess of the Web is arranged protruding, wherein the fastener projects beyond the recess of the web laterally and in this position secures the fastening areas in the spread position.

By forming such a perforation and a recess in the web adjacent to the perforation, after the base element and the fence mat arranged on the base element have been fastened, an additional fastening means can be arranged that penetrates the safety element and protrudes into the base element, in order to provide even greater protection, for example against vandalism or unwanted removal of a fence panel from the base member.

It can particularly preferably be provided that the fastening means is formed by a screw.

A screw that passes through the hole in the securing element and into the mouth of the web represents a simple fastener that is easy to assemble. The screw engages so far into the base element that its threads opposite the screw head secure the expandable fastening areas of the base element contacted and possibly even spread open in the fixing position. In any case, an adjustment or splaying of the fastening areas in the direction of the central point, which effectively prevents the base element from being removed from the perforation that forms the receiving opening of the fence post, is prevented.

A screw of this type can, for example, have an attachment point for a special tool on its screw head, so that it can only be removed with a special tool that is only available to appropriate fitters.

Also a screw removal preventing attack could be provided here to prevent later removal of the screw and thus increase the security of the fence.

Finally, it can particularly preferably be provided that a cover part is provided, which can be fastened or is fastened to the horizontal part of the T-shape of the safety element, which in the fastened position optionally closes the perforation flush and covers the fastening means.

Such a cover part according to the invention covers the screw or the fastening means that penetrate through the base element, so that this is not visible from the outside.

Parts of a fence 1 are shown in the figures. An assembly of a fence 1 is shown in detail in 5 shown. The fence 1 consists of fence posts 2 and fence panels 3. The fence panels 3 in turn consist of lattice bars 4 and 5 which are arranged vertically and horizontally to the ground and are connected at crossing points.

The respective fence mat 3 is attached to the fence post 2 with a holder ( 5 ) or attachable. The holders have a base element 6 which is fastened to the fence post 2 by means of a fastening element which engages in a receiving opening in the fence post 2 ( 5 until 7 ) or can be attached. The fastening element 6 has parallel webs 7 , which on the one hand form support areas 15 for horizontally extending bars 4 of the fence mat 3 . The webs 7 engage behind vertical bars 5 of the fence panel 3, so that the fence panels 3 or their bars 4 and 5 can be positioned and fixed on the base element 6. It is fixed by means of a securing element 11 which covers the webs 7 or at least covers the area between the webs 7 and fixes the rods 4 and 5 of the fence mat 3 to the base element 6 .

According to the invention, the fastening element is formed by fastening regions 8 that protrude from the base element 6 and can be inserted or inserted into the receiving opening of the fence post 2 formed by a perforation and spread or can be spread open in the inserted position. At least one fastening area 8 is designed like a hook at 9 on or near a free end area. In the fixing position inserted into the receiving opening formed by the perforation, this hook-like formation 9 engages behind the edge 10 of the perforation and thus fixes the base element 6 in this position on the fence post 2. By grasping behind the hook-like end region at 9, removal of the base element 6 or of the base element 6 protruding attachment areas 8 from the perforation forming receiving opening of the fence post 2 effectively prevented. In addition, according to the invention, the securing element 11 has a protruding web 12 which, in the intended assembly position in which the securing element 11 is attached to the base element 6 , engages in the fastening areas 8 or passes through them and thereby spreads the fastening areas 8 open. In this spread position of the fastening areas 8, the securing element 11 is fixed to the base element 6 and a removal of the fence mat 3 or the rods 4 or 5 of the fence mat 3 from the base element 6 is effectively prevented. In addition, the hooking of the hook-like end at 9 is ensured by the securing element 11 .

As can be seen from the figures, the securing element 11 has an approximately T-shaped cross section. The vertical part of the T-shape forms the protruding web 12 and the horizontal part of the T-shape fixes the rod 4 of a fence mat 3 on the base element in the intended installation position, i.e. in the position in which the securing element 11 is arranged on the base element 6 6.

To assemble such a fence 1 according to the invention, a fitter first only has to prefix the base element 6 according to the invention by inserting the fastening areas 8 into the perforation of the fence post 2 that forms the receiving opening, until the hook-like end areas (at 9) reach behind the receiving opening and there automatically move into a fixed position to pivot. The fence panel 3 or fence panels 3 can then be arranged on the base element 6 in a manner known per se. To fix the fence mats 3 in place, the securing element 11 according to the invention is merely pushed into the opening of the base element 6 . When it is pushed in, the vertical part of the T-shape of the securing element 11, which forms the protruding web 12, makes contact with the fastening areas 8 of the base element 6 and, if necessary, displaces them to the outside. This effectively prevents the fastening areas 8 and in particular the hook-like ends 9 formed thereon from pivoting into a position in which the base element 6 can be removed from the receiving opening of the fence post 2 forming the hole. No special tools are required to assemble such a fence according to the invention and it can be assembled within a very short time if only a small number of parts are kept in stock.

The fence panels 3 are effectively protected against removal by the securing element 11 .

As in particular from the 1 and 2 As can be seen, the protruding web 12 and the fastening areas 8 of the base element 6 can have friction-increasing means 13 at least in their contact area. This friction-increasing means 13 can also consist of latching elements. Such friction-increasing means 13 or locking elements according to the invention make it more difficult to remove the securing element 11 or its protruding web 12 from the fastening area 8 of the base element 6.

To facilitate assembly, as in particular from the 1 , 4 , 6 , 7 , 8th and 9 visible, be formed at the free ends of the attachment areas 8 feeding aids, in the exemplary embodiment chamfers 14.

In the exemplary embodiment, the hook-like end region 9 is formed by a hook contour, with the contour pivoting automatically into the fixing position after insertion into the perforation of the fence post 2 and the desired position of the base element 6 being reached, and the base element 6 being fixed to the fence post 2 .

Like in particular 5 As can be seen, two fence mats 3 arranged in a mutually aligned position can also be fastened to a base element 6 .

As shown in the figures, both fastening areas 8 can also be hook-like (at 9) at or near their free end area. In the intended assembly position, both hook-like end regions (at 9) engage behind the edge 10 of the perforation forming the receiving opening, which edge is adjacent to the fastening region 8.

This enables the base element 6 to be held particularly securely on the fence post 2 .

In order to effectively prevent unwanted removal of the fence panels 3 from fence posts 2, in a further embodiment of the invention, which is in the 7 until 10 is shown, the horizontal part of the T-shape of the securing element 11 has a perforation 16 which opens into a recess 17 formed on the vertical part of the web 12 . In this case, in a particularly secured target assembly position, a fastening means can be arranged that extends through the perforation 16 and projects into the recess 17 of the securing element 11 . The fastening means also protrudes laterally beyond the recess of the securing element 11 and secures the splayed fastening areas 8 in this position. effectively prevented.

A fence secured in this way is therefore largely protected against vandalism or attempts at manipulation.

In the exemplary embodiment, how in particular 8th As can be seen, the fastening means is formed by a screw 18, which also has a screw head, which is not shown in the figures and is protected against manipulation, or has a tool grip arranged there. This can be, for example, a tool attack for a special tool or a tear-off head that effectively prevents removal.

In addition, a cover part 19 is provided in this exemplary embodiment, which can be fastened or is fastened to the horizontal part of the T-shape of the securing element 11 . If necessary, the hole 16 can be closed flush by the cover part 19 in the fastened position and the fastening means, for example the screw 18, can be hidden from the outside.

The invention is not limited to the exemplary embodiment, but is variable in many ways within the scope of the disclosure.

All individual and combination features disclosed in the description and/or drawing are regarded as essential to the invention.
