Abstract

The secure case according to the invention consists of a known textile structure which is resistant to cutting and has integrated conductive thread layers which trigger an alarm signal in the event of being subjected to mechanical stressing. If use is made of spacer fabrics which are resistant to cutting, the inner surfaces of the upper side and the entire underside, or the inner surfaces thereof, are conductive. Additional weft threads are arranged as spacers, parallel to the spacing threads, between the upper side and underside, in order to prevent unintended contact under the action of pressure.

Description

Security packer

The cut-resistant textile safety packaging device relates to cases and bags, e.g. Carrying bags, bicycle and motorcycle bags, belt bags and rucksacks u. Ä., Which are protected against mechanical damage and theft by an alarm function.

With the increase of petty crime and vandalism, for transporting valuables, vandalism and theft-proof flexible transport containers such as e.g. Valuable cargo bags, travel bag, etc. asked. For the mechanical protection of the textile structures used, there are a variety of solutions for improving the cut resistance. The reinforcing material used is spring steel wire and / or para-aramid filament yarn. For the achievement of a high cutting resistance, the formation of so-called cable effects is necessary. These are thread accumulations, which presented a high resistance to the cutting tool. This effect is achieved by loosely fixed and easily displaceable reinforcing threads, which are used in alternation with floats. (AI F- Final Report 33ZBR / 1 / V of the TU Dresden).

Furthermore, it is also generally known to incorporate the cut-resistant layers as separate surfaces in connection with the confection. In EP 0441919A1 for this purpose a weiterrei ßständige textile construction for the packaging of cargo is described, which consists of two tissues, with an interposed metallic knitted net.

A cut-resistant composite structure with a closed top surface for subsequent lamination and a grid-like reverse side with orthogonal, diamond or hexagonal arrangement of the reinforcing threads was produced as a spacer fabric on a right / right warp knitting machine (Finkelmeyer, Technische Textilien 44 (2001), p. 32, 34 -35).

For electronic security of luggage, preferably handbags, very loud sirens are arranged inside, with a kind of ripcord, which is on the wrist of the wearer / the carrier is used. In the case of theft, a continuous tone is triggered when the bag is torn off, which can not be turned off without further ado.

From the company Infineon Technologies AG a way was found to equip large-scale textiles with intelligence, which can be used for a variety of monitoring functions. For this purpose, microelectronic modules are integrated into the textile structure (see, for example, http://www.texbac.de/html/intel teppich.html).

The G PS system is used for retrieving or locating persons or objects. The fields of application of so-called "know-where" solutions are practically unlimited, for which purpose the corresponding electronics with GPS antenna are integrated, for example, in clothing.

The object of the invention is to provide a safety pack device which is cut-resistant, triggers an alarm in the event of damage and can be located at any time. The location should be done via the internal positioning by GPS and transmitter unit which is designed as a GSM module, the owner of the security pack device or another defined receiver to be transmitted.

The security pack device according to the invention consists of a known cut-resistant textile structure with integrated conductive thread layers which trigger an alarm signal in the event of mechanical stress. When using cut-resistant spacer fabrics, the inner surfaces of the upper side and the entire lower side or their inner surfaces are conductive. Between the top and bottom additional to the spacer threads parallel weft threads are arranged as spacers to prevent inadvertent contact under pressure.

According to the invention, a cut-resistant composite knit can be used for the safety pack device, which contains two conductive fabrics with an insulating layer arranged therebetween. In both textile structures, an electrical contact is created when piercing with a cutting tool between the conductive layers, which causes immediate, without major damage to the packing device, alarm is triggered. Stolen safety pack devices can be retrieved or located via a GPS device integrated in the packing device.

The invention will be explained in more detail using an exemplary embodiment. The accompanying drawings show:

The security pack device may be formed as a suitcase, carrying case, motorcycle luggage bag, bicycle luggage bag, backpack, valuables bag, belt bag or other, any shaped flexible transport container. The outer wrapping surfaces 2 of the safety pack device 1 consist of a known cut-resistant textile construction. The use of spacer fabrics with a top 4 and a bottom 5 is advantageous, wherein the inner surfaces of the sides 5 and 7 consist of electrically conductive (partial) weft threads 12, which are kept at a distance by the weft threads 9 even with strong Druckeiwirkung, so no conductive connection arises. The spacer threads 8 ensure the normal spacing of the textile surfaces. The safety pack device incorporates a GPS system from the outside invisibly. When a metallic blade is pierced, an electrical connection is made between the conductive threads 12 which form the inner surfaces of the upper surfaces 5 and the inner surface of the lower surface 7, respectively, whereby an alarm is triggered. The alarm device is integrated in the safety pack device. The alarm can also be forwarded in case of need to a central security point and / or with the owner's mobile preferably as a silent alarm. The cut resistance is ensured by the steel wires, metal threads or para-aramid threads incorporated in a known manner.

As a cut-resistant textile structure, it is further possible to use a composite knitted fabric which contains, inside the composite, two conductive sheets of non-woven, woven or knitted fabric 14 which are electrically separated from an interposed electrically non-conductive insulating layer 15 having high flexibility and low puncture resistance , The top 13 of the composite can be made of prefabricated fabrics such. B. nonwovens or fabrics are made, which can be coated in case of need with a cut-resistant coating material of ceramic substances, glass beads or graphene in the coating composition. The Graphene shares in the layer mass allow not only a cut resistance but also an electrical conductivity of the layer. If there is another conductive layer in the textile composite, there is a short circuit in the case of a puncture with a metallic object (knife). In combination, the reinforcing threads for the cut protection 16 are arranged. The underside of the composite structure 17 may consist of any fabrics. However, it is also possible to realize a closed surface by a thread composite.

The alarm is triggered in a puncture attempt by electrical connection of the conductive thread materials, coatings or films as a result of the cut and contacting the electrically conductive structures.
