Description

Protective fence against wild cats

The invention relates to a protective fence against wild cats, consisting of wire mesh or wire grid stretched on posts and an obstacle projecting downwards from the upper end to one side.

It is well known that protective fences are erected along sections of highway that run through areas rich in wildlife to keep wildlife away from the road. However, the normal protective fences can be overcome by wild cats.

In order to prevent animals such as wild cats, which are very good climbers, from climbing over the protective fences, it has been suggested that a strip of sheet metal with an inverted V-shaped cross-section be attached to the upper end of the fence between two posts in such a way that one leg is held vertically to the post, while the other leg protrudes diagonally downwards from the apex of the sheet metal strip, which forms the upper edge of the fence. However, this solution is relatively expensive due to the high cost of corrosion-resistant or corrosion-protected, profiled sheet metal. The assembly costs are also high because the sheet metal profiles are stiff and can only be adapted to local peculiarities at the construction site with great effort. This results in the cost-effective requirement that the posts must be set up exactly vertically with very even spacing between them so that the sheet metal profiles can be assembled without any particular difficulties. Further problems also arise during dismantling and recycling if the fence is dismantled with the individual metal sections attached

and these bulky parts made of other material must be recycled separately.

The invention is therefore based on the object of providing a protective fence against wild cats which can be manufactured and recycled more cost-effectively and which also blends better into nature.

The above object is achieved according to the invention in that the upper end sections of the posts are angled to one side and are also covered with wire mesh or wire grid in this area, and in that an apron made of wire mesh or wire grid hangs down from the cantilevered upper end of the fence.

The new protective fence can be built using the materials traditionally used for protective fences. These are flexible and can be adjusted using simple wire cutters. The usual fastening techniques for attaching wire mesh and wire grids to posts can be used. The same applies to dismantling such a fence. Since all of its parts are made of wire mesh or wire grids, the view passes through them and is not caught, as it would be on an opaque strip of metal. Finally, the flexible hanging apron made of wire mesh or wire grid is an obstacle that is more difficult for wild cats to overcome than a rigid metal profile, because they would have to climb around the lower edge of the apron, which swings when touched.

The invention is explained in more detail below using an example embodiment shown in the drawing. Show:

The fence shown consists of tubular posts 10, each having a straight lower section 12 and an angled upper section 14 and in the usual way
covered with a square wire mesh 16. The posts 10 are rammed into the ground with their lower sections 12 at a distance of e.g. 3 m and then have a height of e.g. 2 m. After several posts have been rammed in, a concreted post can follow in order to improve the stability of the fence. Alternatively, the posts could also be provided with heavy base plates and on
the earth's surface.

After the lower sections 12 of the posts 10 have been driven into the ground in the example case, the
upper angled sections 14 with a suitable tubular cross-section are plugged or inserted and fixed, for example, by means of a screw. In the example,
the angled post sections 14 have a length of 60
cm, because square wire mesh of this width is available in rolls. If narrower wire mesh

of e.g. 50, 40 or 30 cm width is available, the upper sections 14 of the posts 10, which in the example case are angled at 45° to the vertical, can also be correspondingly shorter. Since the fastening of the galvanized or plastic-coated square wire mesh 16 with a width of 2 m to the lower, vertical post sections 12 and with a width of 60 cm to the angled upper post sections 14 is carried out in the conventional manner by means of tension wires 18, which are fastened to the posts 10 by means of tension wire holders 19, this known technique for producing wire fences does not need to be discussed in more detail.

The special feature of the fence shown, apart from the bending of the upper sections 14 of the posts 10, is that an apron 20 is also attached to the uppermost ends of the posts 10 and the tension wire 18 extending between them. In the example shown, this apron is also about 60 cm high and hangs down freely. Because of the more precise appearance, spot-welded wire mesh is preferably used for the apron 20, which is inherently more rigid than normal wire mesh. In principle, however, the latter could also be used for the apron 20. The plastic-coated or galvanized wire mesh can be used in individual pieces that are about as long as the distance between the posts 10, or rolled up in longer lengths. In both cases, attaching the apron 20 is very simple. It is sufficient if the wire mesh of the apron 2 0 is attached to the posts at a distance of approximately 1 m using eyelets 22 on the top tension wire 18 and the top tension wire holders 19. Since this connection is relatively loose and flexible, large tolerances in the distance, height and vertical extension are also possible.

direction of the posts has no negative impact on the installation of the apron 20.
