Protective net

Protective nets for catching people, vehicles, objects and the like are known.

However, the previous safety nets have the disadvantage that these give the falling body a rebound, which can cause shock, compression or other physical injuries to people.

The aim of the innovation is for accident prevention purposes or To provide a protective net for blocking purposes, which does not have these disadvantages and, if possible, in the event of an impact a body to be captured does not rebound, but absorbs the falling or impact forces through its own stretching deformation.

This object is achieved by the present innovation in that the elements forming the protective net by a Combination in a certain mechanical arrangement and material selection or setting of the material properties are specifically adapted to the purpose of use.

The object of the innovation is a protective net, in which the network is provided with an edging line that is tied with binding thread is posted to the network, characterized in that the

920027

Tying thread in at least three adjacent stops gene is arranged on the mesh side,

Figure 1 illustrates a special embodiment of the protection * * network, the edging line 1 being drawn through the meshes located on the outer edge of the network 2 and in this Arrangement with binding thread 4 is posted.

In a preferred embodiment, the edging line 1 consists of a rope whose elongation at break value is at least 1/5 lower than the elongation at break value of the network fabric used. In the preferred embodiment, the binding thread has one Elongation at break value which is equal to or less than the elongation at break value of the network fabric.

As shown in FIG. 1, the network is on the outside the mesh-Khc sens side at least twice on both sides of the knot 3 with the binding thread 4 · to the binding line 1 posted.

To attach the protective net, the edging line 1 has at least 5 thimbles 6 and given «* · if one or more, depending on the size of the protective net Thimbles 6 arranged on the sides.

In a particularly preferred embodiment, the binding thread 4 consists of synthetic fiber material, which is used for stabilization the strength properties when exposed to light is colored black.

Figure 2 illustrates a special embodiment of the Scttutznotzes, wherein light-reflecting marking elements 7 are placed or incorporated on the edging line 1 or in the edging line 1. This ensures that the Limitation of the protective net when it is exposed to light

- 5 - emerges.

So that the protective net even under unfavorable weather conditions from plant or animal pests does not rot prematurely, the protective net has an impregnation of algicides and / or fungicides and / or Bactericidal.

This impregnation is expediently carried out with active ingredients from the genaiift th type carried out, which a yellow and red respectively Have their own color, since the presence of one of these colors - similar to an indicator - indicates the presence of the protective impregnation can be easily recognized and, moreover, the boundary of the protective net is designed to be more easily recognizable. In addition, the preferably black impregnated twisted binding thread is lighter due to the optical contrast effect can be checked against unintentional damage or wear.

Characterized in that the binding thread 4- arranged at least in three adjacent stops on the mesh side .des network is, the network is mechanically connected relatively firmly and with little stretch to the edging line 1.

This arrangement helps to make the protective net rebound-free. This effect can be obtained with a particularly high degree of certainty if the network is given a predefined Elongation granted by thermosetting. Through this thermal Treatment can be the Nefczflimaterial, which as the starting material wifcä used low stretch, about 8 to 16 # elongation at break obtained, where nsrCh der ^ is the elongation at break depending on the used Number of twists when making the net twine, the elongation at break is increased by about 5 to 10 units. To the To obtain optimal mechanical properties of the protective netting, the thermal treatment of the protective netting in

take place in two stages. In the first stage there is thermal treatment with the application of voltage and thereby the nodes fixed. Thereafter, the thermal treatment continues stress-free in order to achieve the optimum elongation at break for the finished network Example, $ 25- $ 30, to be granted.
