Description

ELASTIC BELT ASSEMBLY WITH CONDUCTIVE SURFACE

The invention relates to an elastic covering arrangement comprising a conductive filament surface.

From DE 199 27 213 Cl a covering arrangement made of elastic fabric of synthetic fibers is known, which serves as a base during sports fencing. The synthetic fibers of the fabric are completely coated with a corrosion resistant metal. The tissue is in this case designed as electrically conductive tissue, so that hits can be made recognizable by optical or acoustic signals. The coated fibers are embedded in a latex-like thermoplastic matrix. The covering arrangement is fixed, for example, with the aid of adhesive tape directly on the floor of a sports hall. When not in use, the covering arrangement can be folded together, in particular rolled up.

The object of the present invention is to further improve the handling of the lining arrangement.

Confirmation copy | To solve the problem, the invention with the preamble of claim 1, characterized in that at least one of the filament surface having top layer and a bottom layer are provided, wherein the bottom layer is formed as an anti-slip layer.

The particular advantage of the invention is that the covering arrangement has at least two layers which assume different tasks and are designed to be optimized for the respective task. The top layer has the required conductivity for the sport fencing and mechanical stability or robustness. For customization of the covering arrangement, the synthetic filament yarn can be dyed customer-specific. Moreover, further color markings, for example for marking the center line, start line, lateral boundary or warning zone, can be introduced into the top layer. The conductivity is preferably below 10 Ω / cm ² .

Optionally, the topsheet layer may be formed as a sealed layer. As a result, the abrasion resistance and the durability are further improved. For example, silicone can be used for sealing.

In contrast, the underside layer serves to secure the lining arrangement against slipping. The anti-slip layer can therefore be optimally designed for this task and independently of the top layer. In particular, it is not necessary to make the underside layer or the entire covering arrangement conductive.

Due to the elasticity of both the topsheet and the backsheet layer, the pad assembly can be easily collapsed or rolled up. The inherent resilience of the two layers ensures that the filament is not damaged during folding or rolling up and the conductivity of the filament surface is maintained. According to a preferred embodiment of the invention, the anti-slip layer is based on polyurethane. The use of polyurethane means that the covering arrangement is sufficiently strong on almost all sports floors without additional measures. A fixing of the covering arrangement after spreading, for example by means of adhesive tape, can therefore usually be dispensed with. As a result, simplifies the structure of the pad assembly, so that especially in training mode, the infrastructure can be made quickly available and the net training time can be maximized. Moreover, the degradation simplifies, since the pad assembly can be easily collapsed or rolled up. The release of adhesive tape and the removal of adhering to the hall floor or the covering arrangement adhesive residues eliminated.

According to a development of the invention, a shock-absorbing intermediate layer is formed between the top layer and the bottom layer. Advantageously, by the provision of the intermediate layer, a coating-imminent damping realized, which reduces the burden on the athlete. At the same time the deposit of the lining arrangement on the ground is further improved by the damping intermediate layer, that is, the intermediate layer counteracts a displacement of the lining arrangement.

According to a development of the invention, the intermediate layer is formed as felt and in particular as needle felt. The felt is preferably made in a weight range of 500 to 1500 g / m ² and has a thickness of 1.5 to 3.5 mm. Advantageously, it has been shown that the realization of the intermediate layer as a felt with the properties mentioned represents a particularly good compromise with regard to damping properties and elasticity on the one hand and handleability and mechanical stability on the other hand. In particular, the pad assembly can be readily rolled up and carried by a single person.

According to a development of the invention, the top layer and the bottom layer are laminated. Advantageously, the lamination results in stabilization and particular strength in the conductive filament surface, so that a long service life is provided even with intensive use of the covering arrangement. According to a development of the invention, the underside layer is profiled on a flat side facing away from the intermediate layer (underside). Advantageously, the anti-slip property of the covering arrangement improves by the provision of a profiled underside. The profiling is, for example, regularly formed and wave-shaped or sawtooth-shaped.

According to a development of the invention, the layers of the pad assembly are ultrasonically welded at their outer edges. By providing the ultrasonically welded outer edges fraying of the outer edges of the covering arrangement is reliably prevented, even under heavy sporting conditions. At the same time ultrasonic welding can be automated and cost-effective.

Embodiments of the invention will be explained in more detail with reference to drawings.

Show it:

FIG. 1 is a sectional view of an elastic covering arrangement according to the invention,

FIG. 2 shows a combat course for fencing, created from the elastic covering arrangement according to FIG. 1 and partially rolled up;

FIG. 3 shows a bottom view of the lining arrangement according to FIG. 2 in the direction A,

Figure 4 is a section B-B through the pad assembly of Figure 3 and

FIG. 5 shows an alternative underside of an elastic covering arrangement according to the invention. An elastic covering arrangement 1 according to FIG. 1 has an upper side layer 2, a lower side layer 3 and an intermediate layer 4 arranged between the upper side layer 2 and the lower side layer 3, wherein the upper side layer 2, the hiding layer 4 and the lower side layer 3 are substantially parallel to one another in the covering plane extend. The lining arrangement 1 has a layer or sandwich construction, which allows the individual layers 2, 3, 4 to be optimized for different properties or requirements.

The topsheet layer 2 is formed of a conductive textile material, for example, a conductive fabric or knitted fabric of synthetic filament (preferably polyester PES or fibers of other synthetic polymers) and a metal wire. The metal wire serves as a winding yarn for the filament. The filament can be customized and give the pad assembly 1 an individual look. The wrapping thread is used 100% in warp and weft. To achieve a uniform surface, an identical warp and weft yarn is used.

The lower surface layer 3 is formed as a polyurethane-based anti-slip layer. The covering arrangement 1 is laid with the underside layer 3 on a substrate (eg hall floor 6). The underside layer 3 prevents slippage of the pad assembly 1 on almost all surfaces. An additional securing the pad assembly 1 against slipping, for example by gluing the pad 1, is usually not required.

The intermediate layer 4 is produced, for example, as a felt, in particular as a needle felt made of synthetic fibers. The intermediate layer 4 may be, for example, water-repellent and have a specific gravity of 50 to 3000 g / m ² , preferably of 250 to 2000 g / m ² and more preferably of 500 to 1500 g / m ² . A thickness of the felt layer is between 0.5 and 10 mm, preferably between 1 and 5 mm and more preferably between 1.5 and 3.5 mm. The thickness di of the intermediate layer is larger in the present embodiment than a sum of a thickness d ₂ of Top layer 2 and a thickness d _{3 of} the bottom layer 3. This leads to advantageous damping properties.

The low specific weight of the felt layer 4 allows easy handling of the covering arrangement 1. Moreover, the felt layer 4 ensures a favorable degree of damping and elasticity in the thickness and weight range according to the invention. In particular, the joints are spared athletes and allows use of the pad assembly directly on a hard surface. An intermediate construction, for example made of wood, is not required.

The top layer 2 and the intermediate layer 4 are connected to each other. In particular, the top layer and the intermediate layer 4 may be formed laminated. The lamination results in a high stability and strength of the conductive fabric or knitted fabric of the top layer 2.

From the lining arrangement 1, for example, a fight course 5 can be produced for fencing. FIG. 2 shows such a fencing track 5 which is spread out on a hall floor 6. The fencing 5 can be folded or rolled out due to the elasticity of the pad assembly 1 in a simple manner. The low specific weight of the pad assembly 1 allows a single person to roll out and join the fencing track 5.

In order to reliably prevent fraying of outer edges 7 of the fencing track 5 both during repeated assembly and disassembly as well as during exercise, the outer edges 7 are formed ultrasonically welded.

On an underside 8 of the covering arrangement 1, the underside layer 3 (anti-slip layer) can be profiled. An exemplary embodiment according to FIGS. 3 and 4 shows a wavy underside 8 with profiled shafts 10 running substantially parallel. The shafts 10 preferably extend transversely to a longitudinal direction 9 of the fencing path 5. The profiled underside 8 track 5 on the hall floor 6 further improved. At the same time, the profiling ensures additional flexibility and flexibility of the lining arrangement 1.

An underside 8 of the covering arrangement 1 in an alternative embodiment according to FIG. 5 has a crosswise profiling. Of course, any other profilings can be realized, for example, the profiling can be wavy, zigzag-shaped or irregular formed in a covering layer.

The same components and component functions are identified by the same reference numerals.
