CZ15782U1 - Device for marking barrels of firearms - Google Patents

Description

Marking equipment for spherical barrels

Technical field

This technical solution relates to spherical firearms that need a barrel for their operation. It mainly concerns personal firearms, often used by criminals and terrorists. This technical solution will greatly facilitate ballistic expertise.

BACKGROUND OF THE INVENTION

At present, firearms are registered by means of numbers stamped on each of their important parts - on the frame, on the barrel, etc. From the traces left by the projectile shot, it is possible to prove which particular weapon was fired. These tracks are characteristic of each barrel, but cannot be used to identify them unless the weapon and its barrel are available.

The essence of the technical solution

The above-mentioned deficiency removes the marking devices for the barrel weapons according to the present invention. In the barrel of the weapon is located device, which at each shot marks the projectile with a known known imprint, that is, predefined unmistakable features, determined by the device in the barrel itself. The barrel-marking device is formed, for example, by a mechanically modified inner surface of the barrel, which produces an imprint on the circumference of the projectile fired from the spherical weapon. This imprint takes the form of mechanical deformations. Another technical solution of the marking device for the barrel weapons is formed by a ring, in which a system of grooves or sharp projections is formed. When a projectile is fired from a barrel-marked weapon, the ring creates an unmistakable, predefined imprint on the projectile.

Equipping weapons with a marking device for mainly spherical weapons is meaningful only if all such weapons are registered in the database of weapons, respectively. barrel, equipped with the device in question, which allows only by the projectile fired from such a modified weapon always accurately determine from which weapon the projectile fired. It is not necessary to have the weapon itself for this determination. The existence of weapons, respectively. main, equipped with marking devices for mainly spherical weapons, it is therefore not possible to separate them from the database of such marked weapons and vice versa.

Thus, each new weapon or detachable barrel produced with a marking device for mainly spherical weapons will be assigned a unique, unmistakable code. Under this code the weapon will be registered. This will make it easy to determine from what projectile the specific weapon the projectile was fired from, without having the weapon physically available. Marking equipment for mainly spherical weapons also makes it possible to clearly distinguish legally held weapons from illegal weapons, such as terrorist weapons, because all legally held weapons will be equipped with the equipment.

The same results will be achieved by retrofitting of already manufactured and used spherical weapons by adding equipment for marking mainly spherical weapons to their main.

Examples

In the barrel of the weapon we create, for example, a system of grooves or sharp protrusions placed, for example, in one ring, which on the projectile during the shot engrave their unmistakable footprint (barcode equivalent). This will be determined in advance for each manufacturer and each individual weapon.

In weapons manufactured prior to the introduction of this system, a marking ring will be formed additionally. The weapon will be legalized on this occasion by the relevant national authorities.

Industrial applicability

To create a functioning system of registration of barrel firearms and to introduce the possibility to identify only by fired projectile weapons owner.
