Definitions
- the invention relates to large-volume wire bodies for the temporary protection of objects, as auxiliary protection for barriers and fences and also for the protection of plantings and tree crops.
- the known wire fences are primarily designed for long-term stationary use and are dimensioned in terms of size and strength so that they cannot be overcome without technical aids. The same applies to the barbed wire barriers and the tapes with cutting; e.g. DE 43 17 204 AI. Electric pasture fences are known for changing enclosures of cattle pastures,
- the object of the invention are wire bodies consisting of microwires, which have an extremely low volume and basis weight and which have only a limited tensile strength in comparison with the conventional wire obstacles, in order to be able to free themselves in the event of accidental catching without tools and without the risk of injury.
- Such an obstacle should not prevent unauthorized access, but only delay and make it more difficult.
- these wire obstacles should be light in weight and have a storage volume and, depending on the situation, should be able to be deployed in an extremely short time and without special preparation. The service life of these wire obstacles should be adjustable and limited. Finally, scheduled self-dissolution and environmentally friendly self-disposal must be provided.
- large-volume wire bodies made of micro wire with a small wire diameter serve as an obstacle.
- these wire bodies are compacted to a minimum volume and expand after being deployed due to the elastic deformation energy stored in the micro wire or due to external forces.
- a wire cross section of, for example, 10 "8 m 2 which corresponds to a diameter of approx. 0.12 mm
- the edge length is halved to 0.25 m, the same wire length provides 128,000 cubes.
- they have a total weight of 2.7 kg. If the wire diameter is doubled, 25 km of wire length are still available with the same weight.
- the kink and bending strength of the micro wire is increased by the area moment of inertia, e.g. B. with a wire bundle provided by a spacer, by linear trusses or two-dimensional surface structures.
- area moment of inertia e.g. B. with a wire bundle provided by a spacer
- linear trusses or two-dimensional surface structures This means that scaffolding can also be realized for extremely light and very high wire bodies and / or with a certain contour.
- predetermined breaking points or resilience are provided in the micro-wire spanning the wire body, so that unintentional entanglement in the wire obstacle makes it possible for the operator to release himself.
- the wire obstacles are provided; once directly before the time of litter or at the serve. Activation after an adjustable time is also possible via fuses or timers, via an acoustic or radio trigger. Finally, the activation can also be triggered by external influences.
- the three- or quasi-three-dimensional wire body is not formed from one, but from two or more types of wire. A supporting skeleton made of stronger wire is used to absorb the weight even of larger vertical obstacles. A fine-meshed wire mesh is hung in it. In order to make this wire obstacle completely or partially opaque, for example, flat inserts, for example plastic membranes, are also possible as privacy screens or markings.
- the micro wire is additionally designed for self-dissolution and disposal.
- several micro wires are connected at a point or over a line e.g. connected by gluing or soldering.
- the connecting material is designed in such a way that the wire body can move after an adjustable time, e.g. UN light, due to aging and / or due to the natural weather influences, collapses itself and becomes ineffective.
- an adjustable time e.g. UN light

In the initial state, the wire bodies are compactly wound, folded or compressed. The unfolding is preferably carried out by the elastic energy stored in the wire.
- the wire has a circular cross-section or a tube, star, strip, U, X or T profile with a higher buckling stiffness.
- means X2 and X3 are provided to increase the area moment of inertia of the micro wire XI. It is essentially a spacer and truss construction.
- X4 predetermined breaking points in the micro wire Xl with adjustable breaking force to avoid injuries.
- X5 Wire windings integrated in the micro wire XI, which only unfold after tensile load in order to extend the micro wire XI or to develop another wire body X0.
- X6 connection points of micro wires XI also with provisions for self-dissolution of the wire body X0, for example adhesives which are quickly delayed by sublimation or delayed by the action of moisture and / or light or deliberately dissolved by water. In the case of soldered connections, a very long service life and targeted elimination of the wire body X0 can be achieved via electrical corrosion.
