Abstract

Hand gun has a visually readable identification strip on an identification holder (1) which is connected to an electronic data holder (8) with electronically readable identification. At least part of said electronic data holder is situated between identification holder and hand gun or on the identification holder. The electronic data holder, formed by a contact-sensitive processing chip or an RFID transponder, is embedded in a recess on the gun. The identification holder forms a functional component of the electronic data holder.

Description

The invention relates to a handgun with a visually readable identifier and an electronic data carrier with an electronically readable identifier.

The visually readable identifier of a weapon, which is mandatory in most countries, is often formed by numbers and letters that are hammered into the handle when it is made of metal. In a handle made of plastic, a metal plate is used with stamped identifier, which is embedded in the plastic. This identifier is intended to ensure that an authorized person can not unlawfully pass on his weapon. By overstamping or the like manipulation of the visually readable identifier of the claimant who has passed the weapon, but no longer be determined. It is therefore also known to provide the weapon with an electronic data carrier in which the identifier is additionally stored in electronically readable form.

If, for example, out DE 39 11 804 A1 known, to a contact microchip is used, however, the contacts are visible, so that such a disk can be easily replaced. To EP 0 955 618 A2 Therefore, an RFID transponder is used, which is embedded in the handle of the weapon visually untraceable. However, such a transponder is easily findable on the basis of the strength of the coupling with a commercially available RFID reader and thus interchangeable, so that the cost of embedding the Transponders at an untraceable point is ultimately futile.

The object of the invention is to be able to easily identify manipulations of the identifier of a handgun with the least possible effort.

The invention is based on the recognition that a total exchange of the identifiers, that is to say both the visually readable and the electronic identifier, can not be completely prevented anyway. In addition, by changing the visually visible identifier and deleting the electronic identifier, the claimant who illegally passed the weapon can no longer be determined. The electronic identifier can be destroyed, for example, by the fact that the weapon is placed in a microwave oven. By arranging the electronic data carrier locally separated from the visually readable identifier, the security is thus not noticeably increased.

According to the invention, therefore, the electronic data carrier is connected to the identifier carrier, that is attached to the location of the weapon at which the identifier carrier is located with the visually readable identifier. This significantly reduces costs. In addition, manipulations of the visually readable identifier are easier to detect when the visually readable and electronic identifiers are attached and connected to the same location of the weapon.

The identifier carrier can be formed by a metal plate, for example made of stainless steel, in which the visually readable identifier, for example consisting of numbers, letters or the like, is stamped, embossed, engraved or introduced in another way.

For example, in the case of a handle made of plastic, the identification carrier can be placed in front of the trigger guard, e.g. be provided on the underside of the handle. The electronic data carrier can e.g. be arranged between the identifier carrier and the handle in a recess. Since the metal plate, which forms the identifier carrier, preferably has anchoring sections which are cast or otherwise embedded in the plastic, it and thus the data carrier is securely fixed to the handle.

If, as mentioned, the identifier carrier has anchoring sections which are embedded in the plastic, it is also possible to connect the electronic data carrier to the identifier carrier by arranging the electronic data carrier on an anchoring section and embedding it in the plastic together with it.

Furthermore, it is possible to use the electronic data carrier with the identifier carrier, e.g. by gluing, riveting or otherwise mechanically fixed. This also destroys the electronic data carrier in a manipulation of the visually readable identifier on the identifier carrier, in any case changes recognizably.

The electronic data carrier may be a contact-based memory chip or an RFID transponder.

Memory chips are powered and read via a galvanic connection to the reader. In this case, preferably a memory chip is used with security logic, as it is known for example from smart cards.

In contrast, the energy supply of the RFID transponder and the data exchange between transponder and reader is not done by galvanic contacting, but non-contact, in particular using magnetic or electromagnetic fields. For this purpose, the RFID transponder has a chip which is connected to a coupling element, for example an antenna coil.

The RFID transponder can be connected to the identifier carrier, for example, by the identifier carrier passing through the antenna coil of the transponder. For this, the transponder within the coil may have a slot through which the e.g. formed as a metal plate identifier carrier is plugged so that it overlaps the antenna coil. If manipulated on the metal plate, the antenna is interrupted, making the manipulation recognizable.

Instead of a slot and two slots can be provided within the antenna coil through which the metal plate is inserted, wherein the slots have a distance from each other, which is at least as long as the length of the identifier on the metal plate, so that the identifier between the two slots can be read visually.

The identifier carrier with the visually readable identifier can also be connected to the electronic data carrier by forming a functional component of the electronic data carrier. That is, the identifier carrier may be an electronically integrated component in the data carrier.

For this purpose, the identifier carrier can form different components of the data carrier. Thus, in the case of a chip, a contact of the chip can be connected to the identification carrier embodied as a metal chip, so that the metal chip forms, for example, a contact for the galvanic connection with the reading device.

If an RFID transponder is used, the identifier carrier may be e.g. form a part of the coupling element or a part of the line between the chip and the coupling element.

With inductive coupling between read element and transponder, the identifier carrier can thus be used, for example. form part of the antenna coil or the dipole antenna.

Apart from the galvanic coupling and the inductive coupling between the electronic data carrier and the reading device, a capacitive coupling can also be provided. Thus, with capacitive coupling of the identifier carrier form a coupling surface of the transponder for a coupling surface of the reader. Also, on the one hand a galvanic and on the other hand a capacitive coupling can be provided. Thus, the chip of the data carrier on the one hand be connected to at least one coupling surface for capacitive coupling with the coupling surface of a reader and on the other hand with the identifier carrier to form a contact for electrical connection to the reader. In the case of capacitive coupling, the two coupling surfaces on the data carrier or reading device are placed parallel to one another to form a plate capacitor.

If the identifier carrier is a functional component of the electronic data carrier, the electronic data carrier is destroyed in a manipulation of the identifier carrier, in any case changed so that the electronic identifier can no longer be read.

In order to still be able to read the data carrier, if the identification carrier forms a contact for the chip, an additional hidden contact can be provided on the weapon, which is connected to the chip in order to be able to connect the reading device.

If the chip of the data carrier is connected on the one hand to a coupling surface for capacitive data transmission and on the other hand to the identification carrier for galvanic contacting with the reading device, an additional coupling surface for capacitive data transmission can be provided, which is embedded in the plastic of the grip, also to conceal it ,

On the other hand, in the case of inductive coupling, if the tag carrier is e.g. forms a part of the supply line from the chip to the antenna coil or part of the antenna coil and can no longer be read by manipulation of the identifier carrier of the transponder, preferably another antenna coil or the like inductance connected to the chip to still read it.

If the handle is made of plastic, the electronic data carrier can be manufactured as a so-called "Molded Interconnecting Device" (MID). Thereafter, the image of the circuit is engraved with the laser beam in the surface of a plastic containing a laser-cleavable organometallic complex. The metal particles formed during the laser treatment of the organometallic complex then serve as crystallization nuclei for the subsequent reductive metal deposition to build up the circuit.

After the MID method, for example, the lines, the antenna coil, the coupling surfaces, contacts and the like can be prepared and then poured into the plastic, injected or embedded in another way. However, instead, it is also possible to use corresponding stamped and bent parts for the circuit for embedding in the plastic.

As shown in Figure 1, an identifier carrier 1 consists of a metal plate or strip, e.g. made of stainless steel. At the middle section 2, the visually readable identifier (not visible in FIG. 1) is embossed on the underside, for example, or incorporated in another way. The lateral sections 3, 4 form anchoring sections, which are embedded according to Figure 2 in the plastic of the handle 5 of the gun 6, on the underside in front of the trigger guard 7. On the anchoring section 3, an electronic data carrier 8 is arranged, the thus also in the handle 5 is embedded. The middle section 2 with the visually readable identifier, however, is arranged on the surface of the handle 5.

According to FIG. 3, an RFID transponder 9 with antenna coil 10 as data carrier 8 is mechanically fastened to the identification carrier 1, for example with rivets 12, soldering points, by laser welding or the like.

A further mechanical fastening is shown in FIGS. 4 and 5, according to which the identifier carrier 1 with the identification 13 consisting of letters and numbers passes through the transponder 9 in the middle within the coil 10. According to FIG. 4, a slot 14 is provided inside the coil 10 through which the identifier carrier 1 is inserted. In contrast, according to Figure 5, two slots 15, 16 are provided within the coil 10, through which the identification carrier 1 is inserted, wherein the slots 15, 16 have a distance which is greater than the length of the identifier 13 in order to read them visually ,

According to Figure 6 to 8, a transponder 9 is embedded in the handle 5 of the gun 6, wherein the identifier carrier 1 is a functional component, namely a part of the antenna coil 10 of the transponder 9, to which the chip 17 is connected. While the antenna coil 10 and the chip 17 are embedded in the handle 5, the identification carrier 1 is arranged with the identifier 13 on the surface of the handle 5 (Figure 8), on the anchoring portion 4 (see Figure 2).

According to FIGS. 9 and 10, the identifier carrier 1 additionally has projections 22 for anchoring in the grip piece 5. While the identification carrier 1 is arranged according to Figure 9 in the middle of the coil 10, it is laterally offset according to Figure 10, whereby the field lines are less damped.

According to FIGS. 7 to 10, the chip 17 is arranged on the outside of the coil 10, so that it can optionally be arranged in a protected position, for example in a metal part of the gun 6. In contrast, the embodiment of Figure 11, in which the chip 17 is disposed within the coil 10, the advantage of greater compactness and thus easier installation.

FIG. 12 shows a section through the antenna coil 10 of the transponder 9 according to FIG. 7, which has been produced by the MID method described above. After attaching the chip 17 and the tag carrier 1 to the antenna coil 10, the antenna coil 10 is cast with the chip 17 or embedded in the handle 5 in some other way.

According to FIG. 13, a memory chip 18 is embedded in the grip piece 5 and, on the one hand, connected to the identifier carrier 1 with the visually readable identifier 13 and, on the other hand, to the contact 19. The chip 18 can thus be read out with the reading device 21 when it is contacted on the one hand with the metallic identifier carrier 1 and on the other hand with the contact 19.

In order to read the chip even if the identification carrier 1 has been damaged, an additional hidden contact 23 is provided in the handle 5.

According to FIG. 14, the transponder 9 can be coupled to a reading device 24 for inductive data transmission. In order to read the transponder 9 even when the antenna coil 10 is destroyed by manipulation of the identifier carrier 1, a further inductor L1 is connected to the chip 17 and the coil 10, which is cast into the handle 5 or embedded in some other way ,

In the embodiment according to FIG. 15, the memory chip 18 is connected in the grip piece 5 on the one hand to the identification carrier 1 and on the other hand to a coupling surface 25. The identifier carrier 1 is made of metal and is arranged, as usual, at least in the region of the identifier 13 on the surface of the handle 5. The coupling surface 25 is in the vicinity the surface of the handle 5 embedded in the plastic and hidden.

The reader 26 has on the one hand a coupling surface 27, which, when it is arranged parallel to the coupling surface 25, forms a plate capacitor for capacitive data transmission. On the other hand, the reader 26 is galvanically connected via a common ground contact 28 with the identifier carrier 1 to read the chip 18.

In order to read the chip 18 even when it has been manipulated on the identification carrier 1 so that it no longer forms a contact 28, an additional coupling surface 29 is connected to the chip 18, which is also hidden in the plastic of the handle 5.

The capacitive coupling according to FIG. 15 has the advantage that the identifier carrier 1 can consist of virtually any desired shape since no field lines are influenced.

The coupling surface 25 may be provided in the holder of the reader 26. The read data from the reader can be forwarded to another system, such as a PC.

Referring to Figures 16 and 17, two coupling surfaces 31, 32 are connected to the chip 18 on either side of the tag carrier 1, e.g. are introduced into the handle 5 by the MID method.
