Description

FIELD OF THE INVENTION

The invention relates to a mesh fence according to the preamble of claim 1. Accordingly, it is envisaged that the mesh fence, of crosswise spot welded lattice panels arranged on both sides of vertical bars, in particular at the same height, Norizontalstäben and with the lattice panels by a plug-in receiving, spaced apart fence post corresponding Height exists.

TECHNOLOGICAL BACKGROUND

Grid fences are among others out of the DE 2 427 705 A1 known for a long time.

FIG. 1 shows an example of a grid fence from above and / or juxtaposed, self-supporting horizontally or horizontally inclined horizontal bars (1) and vertical or inclined extending vertical bars (2) formed lattice panels, which are fixed to anchored in the ground fence posts (5).

In these known fences, in which the grids are clamped between posts and fastener, always at least two opposite surfaces, or points on the post and separate fasteners for the grid attachment are required. These are usually on the one hand, the surfaces of the fence post and on the other hand terminal strips, Klammem, shaped discs, fittings, counter surfaces, etc.

The types of grid connections are usually expensive and associated with higher installation costs. In many cases, many irregularities such as brackets, screws, strips and discs, which in many cases do not adapt to the color of the fence, disturb the good design of the linear fence.

From the EP 0 443 441 is a generic mesh fence known that allows a pure plug connection between posts and lattice panels, the fence posts are provided with a relatively expensive to produce male and nub-like Verrastungsmittein.

PRESENTATION OF THE INVENTION

The invention is based on the problem of facilitating and accelerating the handling, in particular the installation of mesh fences, and of expanding their possible uses. In particular, it is desired to create a new and economical fencing system of good design, low cost production and easy assembly that meets high demands. The invention solves the problem with a mesh fence with the features of claim 1. Accordingly, in a generic mesh fence provided that the adjacent fence posts for each grid connection in each case at least one Einsteckflansch (6) and the lattice panels to be fastened at their vertical edges pockets or slots (7). According to a preferred embodiment, it is further provided that on the one hand on the, preferably fully automatically produced grid on the, preferably two, vertical edges relatively far projecting, horizontal double wire ends are arranged through which a closed by the last vertical wire unilaterally closed slot is formed. These slots are so large that vertical Einsteckflansche, which are preferably arranged on both sides of the post with the fence aligned, are inserted into the slot.

The invention makes it possible to use very different posts, but also very different lattice panels. The fence posts need only be provided on one side, but preferably on both sides with the Einsteckflanschen invention. The flanges can be worked on any post, for example in the form of sheet metal strips or integrally formed with the post. According to a particularly preferred embodiment of the invention, the surfaces of the fence post and the Einsteckflansche by mutual bends of a flat strip of material, in particular made of sheet metal, may be formed. At a special simple embodiment ( FIGS. 2 and 3 ) only three bends are required. A particularly inconspicuous optical image of the finished mesh fence results in four bends, as in FIGS. 4 and 5 are shown, so that a fence post with triangular cross section is formed. Particularly stable fence posts are created by six bends FIG. 5 , where on both sides of the lattice panels arise in cross-section triangular post parts. In such an integral fencing fence can contact each other vertical edges point or line, in particular by welding connected.

The Einsteckflansche can have very different thicknesses of material, which are less than, equal to or greater than the width of the associated slots in the lattice panels. In particular, a certain bias between the Einsteckflansche and the pockets or slots on the side lattice panel edges can be achieved by doubling, beading or by the direction of escape of the lattice panel slightly inclined, Einsteckflansche.

In order to improve the assembly and / or cohesion of adjacent lattice panels, U-shaped clamps can be provided which engage adjacent edge-side vertical bars of adjacent lattice panels and are secured by overlapping horizontal bars on bent clip ends.

The above-mentioned and the claimed components to be used according to the invention described in the exemplary embodiments are not subject to special conditions of size, shape, material selection and technical design, so that the selection criteria known in the field of application can be used without restriction

Further details, features and advantages of the subject matter of the invention will become apparent from the dependent claims, as well as from the following description The accompanying drawings and table, in which - by way of example - an embodiment of a lattice fence is shown. Also, individual features of the claims neither of Embodiments may be combined with other features of other claims and embodiments.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In the embodiments according to FIGS. 2 to 15 limit the fixed in the ground post 5 the lattice panels 1, 2 in such a way that they can avoid either to the right or to the left. The movement of the lattice panels upward is possibly limited by the fact that in the vertical Einsteckflansche 6 of the post 5 bosses 10 are pressed, blocking the way ( Fig. 5B . 13A The humps 10 are guide points for the lattice panels and also serve for the horizontal alignment of the fence, as well as a support point for graduated grating.

To compensate for dimensional differences between the material thickness of the Einsteckflansche 6 and the width of the slots 7 on the grid, it is expedient to provide you einsteckflansche 6 up to 15 ° deviating from the alignment line, creating a Inclination within the slot 7 is formed and when alignment of the grid with the post, a voltage occurs. This will make the fence rattle-free ( Fig. 10, 11A, 11B ). Comparable is achieved with a vertical bead 11 in the Einsteckflansch 6 ( Fig. 5C and 10 ).

The effects of the bosses 10 or beads 11 can also be achieved by edge elevations 9 on the free longitudinal edges 6A of the insertion flank 6. Such edge elevations are very easy to do e.g. by an embossing step or (not shown) by Randeinkerbungen and bending out an edge portion realize.

If, in the individual case, the Einsteckfilansch 6 be stronger than the width of the slot 7, the vertical edges 3 of the lattice panels get a stronger end bar 13 ( Fig. 9 ), whereby an enlargement (16) of the slot 7 is achieved during welding of the grid. Another, version for better introduction of the edge of the Einsteckflansches 6 in the slot 7 of the lattice panel is to achieve the double bar ends 4 of the lattice gate opposite by wedge-shaped breaking of the inner edges (12) of the horizontal bars 12 ( Fig. 8 ).

A special type of rapid insertion of the Einsteckflansche 6 is achieved in that the opposite horizontal bars 1 are offset in the longitudinal direction by about 6 mm or different lengths ( Fig. 7 ). In this case, grid and / or posts at an angle plugged together, so that a support, or a stop 15 is made by the longer horizontal bar end, for better uniform insertion.

The simplest way of producing a post 5 for this fencing system is achieved by sending endless strips of strip of the required width through an automatic roll forming machine equipped with 3 bends ( Fig. 2, 3rd and 12A / B ) produces the post profile and equips with required 6 einsteckflanschen. The profiles obtained in this way 5 to desired lengths to a finished post cut. These open, bead-shaped posts 5 are stackable and require the least space for storage and transport.

A development consists of post profiles in the same production machines with multiple bends (four bends after Fig. 4A-C , six bends behind FIGS. 5A-C and 13 ), wherein the edges of the strips of sanding strip are respectively formed to einsteckflanschen 6 of the posts. The other embodiments of posts ( Fig. 14 A to H ) show further profiles with 3, 4 and 6 bends, the final product is always a finished post with appropriately formed Einsteckflanschen 6.

1. 1. Setzen eines Pfostens im Betonfundament oder Befestigung einer Bodenplatte des Pfostens auf einem Untergrund.
2. 2. Danach wird ein Rand einer Gittertafel mit den überstehenden Stabenden über den benachbarten Flansch des stehenden Pfosten geschoben.
3. 3. Der andere Rand des Gitters wird durch Einführen des Flansches nächsten Pfostens den zweiten Schlitz der Gittertafel eingesteckt.
4. 4. In diesem Zustand wird der Pfosten einbetoniert und ausgerichtet. Die Pfosten/Gitterverbindung ist perfekt.

Zur Montagevereinfachung ist es vorteilhaft, in den Flächen der Einsteckflansche 6 Buckel 10 oder Sicken 11 in dem Blechstreifen anzubringen, an denen die Gittertafeln auf vorbestimmter Höhe hängen bleiben. Ferner kann als Montagehilfe eine Schelle 18 vorgesehen sein, die den letzten Vertikalstab 3 einer Gittertafe umgreift und mit einer Schraube durch den Einsteckflansch 6 des Pfostens 5 die Gittertafeln am Herausgleiten hindert.The assembly of this fence system according to the invention is carried out as follows:

1. 1. Setting a post in the concrete foundation or fixing a floor plate of the post on a substrate.
2. 2. Thereafter, an edge of a grid panel is pushed with the projecting rod ends over the adjacent flange of the standing post.
3. 3. The other edge of the grid is inserted by inserting the flange of the next post the second slot of the grid panel.
4. 4. In this condition, the post is set in concrete and aligned. The post / grid connection is perfect.

To simplify assembly, it is advantageous to mount in the surfaces of the Einsteckflansche 6 boss 10 or beads 11 in the sheet metal strip on which the lattice panels hang at a predetermined height. Further, as a mounting aid, a clamp 18 may be provided which engages around the last vertical rod 3 of a lattice gate and with a screw through the Einsteckflansch 6 of the post 5 prevents the lattice panels from slipping out.

An additional safeguard against digging the lattice panels can after Fig. 12A / B can be achieved by bending the upper, outer corners 17 of the post 5, whereby the material thickness of the Einsteckflansche 6 is doubled and thereby greater than the width of the slot 7 of the grid panel.

To increase the stability of the fence posts produced by folding, it is within the scope of the invention to weld adjoining edges (contact points 8) in places or continuously ( Fig. 4C, 5C . 14A, 14D, 14 14G ).

An alternative mounting aid and fuse after Fig. 15A / B consists of a U-shaped bracket 19 which comprises two adjacent vertical end bars 3 of two lattice panels horizontally, which are inserted with their rod ends 4 on the Einsteckflansche 6 of a fence post 5. To protect the bent ends 20 of the U-shaped bracket 19 surround the horizontal bars 1 of the lattice panels after the clamp 19 has been pivoted into the illustrated securing position by about 90 °, wherein the U-base forms the pivot axis.

With the screwless and tool-free mullion / grid connection and the advantages in production and assembly, the fence system according to the invention opens up new ways and possibilities.
