Description

The invention relates to a safety device for a rifle according to the preamble of claim 1.

Due to increasing frequency of abuse, efforts are often made to prevent the unauthorized use of handguns. So was u.a. Claiming to store weapons only in gun cabinets or vaults with biometric security. Also for immediate securing of the weapon, electronic security mechanisms with personal authentication systems have already been proposed in addition to mechanical solutions with lock-type latches. However, the previously known security devices are usually designed for pistols or revolvers and have a relatively complex locking mechanism.

From the US 2006/0080881 A1 a security device with a insertable into a magazine shaft instead of a magazine insert is known, on which a biometric sensor and a coupled to the biometric sensor adjusting device for actuating a Verriegelungsmechnismus for the detachable barrier of the magazine shaft is arranged. The locking mechanism consists of two via a magnet assembly mutually adjustable bars, which are designed to engage in corresponding recesses on the magazine shaft.

The object of the invention is to provide a safety device of the type mentioned, which allows simple means improved security against unauthorized use of guns.

This object is achieved by a securing device having the features of claim 1. Advantageous embodiments and advantageous developments of the invention are specified in the dependent claims.

The locking mechanism suitably contains locking elements arranged on the insert for locking the insert in a magazine shaft of the rifle in a lockable manner. Advantageously, the locking mechanism may include locking elements associated with the locking elements that are movable between a locking position to prevent removal of the insert from the rifle and a release position to remove the insert from the rifle. The adjustment of the locking elements is advantageously carried out by the preferably designed as an actuator actuator, wherein the locking position, for example. can be achieved in a mechanical manner when inserting the insert into the magazine shaft and the release or unlocking position by the adjusting device upon detection of the proper data by the biometric sensor. But it is also possible that both the displacement of the locking elements in the release position and the displacement of the locking elements in the blocking position by the adjusting device in dependence on the data determined by the biometric sensor.

In the FIGS. 1 to 6 there is shown a security device for preventing unauthorized use of a rifle. The security device includes an insertable in the magazine shaft of a rifle instead of a magazine insert 1, which includes a locking mechanism 2 for releasably fixing the insert 1 within the magazine shaft. In the embodiment shown, the insert 1 consists of a magazine-shaped housing which comprises a lower part 3, a frame-shaped upper part 4 fastened on the lower part 3 and an upper cover, not shown. The adapted to the shape of the magazine shaft frame-shaped upper part 4 is suitably made of plastic, while the lower part 3 may consist of metal or plastic. The insert 1 can also be made in one piece from plastic or other suitable material. The lower part 3 is designed such that it closes when inserting the insert 1 in the magazine shaft whose opening in the fixed position.

The locking mechanism 2 comprises in the embodiment shown, two arranged on the opposite longitudinal sides of the frame-shaped upper part 4 of the insert 1, laterally resilient locking elements 5 with outer or inner locking lugs 6 for latching engagement in corresponding counter-elements on the housing or system box of the rifle. The locking lugs 6 are designed such that they automatically engage in the associated counter elements on the housing or system box of the rifle when inserting the insert 1 in the magazine shaft of the rifle and thereby fix the insert 1 within the magazine shaft.

In the illustrated embodiment, the locking elements 5 are designed as formed on the upper part 4 and divided by slots 7, downwardly projecting locking tabs with outside gripping pieces 8 at the downwardly projecting ends. To remove the insert 1, the opposite tab-shaped locking elements 5 by compressing the two handles 8 inside are pressed so that the locking lugs 6 get out of engagement with the corresponding counter-elements on the housing or system box and the insert 1 can be removed from the magazine shaft.

Like from the FIGS. 3 and 4 shows the locking mechanism 2 further comprises a arranged on the upper side of the lower part 3 locking mechanism with two transversely to the longitudinal direction of the insert 1 in the lower part 3 slidably disposed locking elements 9, which has a in FIG. 5 shown longitudinal slide 10 between a in FIG. 3 shown blocking position and a in FIG. 4 shown release position are movable. At the in FIG. 3 shown blocking position, the two locking elements 9 are pressed over the longitudinal slide 10 to the outside against the tab-shaped locking elements 5, whereby a compression of the locking elements 5 and thus unwanted removal of the insert 1 is prevented from the magazine shaft. For displacement of the two locking elements 9, the longitudinal slide 10 in FIG. 5 recognizable wedge-shaped footprints 11 for contact with corresponding inclined mating surfaces 12 of the locking elements 9. At the in FIG. 4 shown release position of the longitudinal slide 10 is corresponding FIG. 5 pulled back, so that the locking elements 9 are pressed by the resilient locking elements 5 or a separate return spring inward.

At the bottom of the base 3 is an in FIG. 2 shown biometrics sensor 13 for detecting person-specific biometric data arranged. The biometric sensor 13 may be formed, for example, as a fingerprint recognition sensor or as a sensor for detecting other biometric characteristics. In a particularly expedient embodiment, the biometric sensor 13 may be designed as a line sensor which detects the fingerprint line by line by passing the finger.

The biometric sensor 13 is connected to a in the FIGS. 3, 4 and 6 Logic module 14 shown schematically, in addition to a memory unit for storing in a learning phase read reference data also includes a processor for comparing the data detected by the biometric sensor 13 with the reference data and for driving a here designed as actuator or actuator actuator 15 as a function of the processor performed data comparison. The logic module 14 is mounted on the bottom plate 3 of the insert 1 together with the adjusting device 15 and a power supply device 16 designed as a battery unit. The Power supply device 16 for supplying the logic module 14 and the adjusting device 15 may consist of a battery compartment with one or more batteries. The adjusting device 15 designed as a servomotor or actuator is connected to a longitudinal slide 10. By appropriate control of the actuating element 15, the locking elements 9 via the longitudinal slide 10 between the in FIG. 3 shown blocking position and in FIG. 4 be moved shown release position.

The displacement of the longitudinal slide 10 and thus the adjustment of the locking elements 9 is controlled in response to the biometric sensor 13, which detects the fingerprint or other suitable biometric data and transmitted to the processor within the logic module 14. In the processor 11, the data detected by the biometric sensor 13 are compared with the reference data stored in the memory unit of the logic module 14. It can thereby be achieved that the insert 1 can only be removed or used by persons who have been recognized as being authorized by means of the biometric sensor 13 and the associated evaluation circuit within the logic module 14.

In the FIGS. 7 and 8 there is shown a securing device in which an additional blocking element 17 for blocking the closure is provided on the insert 1, which is otherwise constructed as in the previously described embodiment. The locking element 17 may consist either of a fixed to the insert 1 or displaceable by the adjusting element 15 locking bolt 18 which engages in the closure of the rifle and prevents its actuation. As a result, the supply of individual cartridges can be prevented.
