Description

DISPLAY AND / OR SECURITY DEVICE FOR A FIRE ARM

description

The invention relates to a display and / or safety device for a firearm. The display and / or safety device is used in particular to identify an uncharged or non-ready state of a firearm and / or to secure a firearm by putting it into a non-ready state by inserting the display and / or safety device is offset. The invention also relates to the use of a display and / or safety device for displaying and / or identifying an unloaded and / or not-ready state of a firearm and a method for displaying an uncharged state of a firearm.

The use of firearms, especially Flandish firearms such as handguns or long guns, is learned and trained within the framework of various training methods. Among other things, training measures are known in which a shooter completes target exercises, for example on a shooting range, in which live ammunition is fired. In exercises of this type, the shooter is given, in particular, a realistic impression of the recoil behavior of the firearm.

However, there are also known practice practices in which no live ammunition is fired. In particular, in the context of dry-firing exercises (in German about "dry exercises" or "dry shooting"), the firearm is operated without a cartridge or only a dummy cartridge without propellant is introduced into the cartridge chamber of the firearm. Performing such dry-firing exercises is generally much safer than performing exercises in which live ammunition is used. However, live ammunition that has been forgotten, for example, in the cartridge chamber or in a magazine of the firearm can pose a risk.

The present invention is based on the object of making exercises with a firearm, in particular dry-firing exercises, safer.

This object is achieved according to the invention by a display and / or safety device for a firearm with the features of claim 1, the use of a display and / or safety device according to claim 14 and a method for displaying an unloaded state of a firearm according to Claim 15 solved.

The display and / or safety device according to the invention for a firearm with a cartridge chamber and a barrel aufwei send a barrel comprises

a dummy cartridge which can be introduced into the chamber of the firearm and has a distal and a proximal end and

- An extended along a central longitudinal axis and at least partially insertable into the barrel of the firearm display element with a distal and a proximal end.

At the distal end of the dummy cartridge and at the proximal end of the display element, corresponding fastening means are arranged which are designed for fastening the proximal end of the display element at the distal end of the dummy cartridge. A longitudinal extension of the display element along the central longitudinal axis is greater than the barrel length of the firearm. The display and / or safety device is designed to clearly indicate to the outside that the firearm, in particular the handgun, is not in a ready-to-fire state and therefore there is no immediate danger from the firearm. As a handgun in the context of this description, a firearm is understood that can be carried by a single person and without additional tools, such as a gun carriage or the like, can be fired. Typically, the handgun is a long or short weapon. In particular, by definition, a handgun is not a long weapon. A handgun in this sense is a handgun whose barrel with the breech closed has an overall length that is shorter than a predetermined length, for example shorter than 25 cm to 45 cm, in particular shorter than 30 cm. Correspondingly, a long weapon is a handgun whose barrel with the breech closed has an overall length that is longer than this predetermined length, for example longer than 25 cm to 45 cm, in particular longer than 30 cm. The handgun can in particular be a handgun within the meaning of the German Weapons Act. Accordingly, the long weapon in particular can be a long weapon within the meaning of the Weapons Act applicable in the Federal Republic of Germany.

When the trigger safety device is used as intended, the barrel of the firearm, especially a handgun, is directed in the distal direction. The opposite direction to this is referred to as the proximal direction. With regard to a shooter using the firearm, in particular hand-held weapon, as intended, the distal (from Latin distare, "to move away") or proximal (from Latin proximus, "the closest") direction is in itself a common way with reference to defines the body of the archer.

In the context of this description, the barrel length is defined as the length of the barrel from a distal end of a cartridge or a dummy cartridge inserted into the cartridge chamber to the distal end of the barrel. This is generally to be distinguished from the total length of the barrel or the pipe length.

The barrel length of the firearm is in particular shorter than the axial length of the display element along the central longitudinal axis. In the assembled state, the end of the display element protrudes from the distal end of the barrel when the display element is attached to the dummy cartridge introduced into the cartridge chamber of the firearm.

In refinements, the fastening means are designed as screw connections.

In refinements, the display element comprises an external thread which extends at least in sections around the central longitudinal axis and along the central longitudinal axis. The proximal end of the display element is in particular provided with the external thread so that it can be screwed into a correspondingly complementary internal thread at the distal end of the dummy cartridge.

In embodiments, the external thread extends over at least 30%, preferably over at least 50%, particularly preferably over at least 75% of the longitudinal extent of the display element along the central longitudinal axis. The display element is preferably designed to be shortened to a certain length which is predetermined by the barrel length of the firearm. For example, part of the display element is cut off with the aid of a knife or scissors. Since the external thread extends over a relatively large part of the longitudinal extent of the display element, it can be ensured that a shortened display element can also be releasably attached to the dummy cartridge by means of the screw connection provided for this purpose. In alternative embodiments, the fastening means are designed as a bayonet connection, for example. Both bayonet connections and screw connections are fastened or loosened by a relative rotation of the components to be connected and are equally suitable for fastening the display element to the dummy cartridge when the latter is already inserted in the cartridge chamber.

In embodiments, the display element is at least partially made of cutable material, in particular made of cutable plastic, so that it can be shortened to the desired length in a particularly simple manner. In particular, the material should be able to be cut with a knife or a gravity.

In refinements, the dummy cartridge is designed to be flexible or deformable at least in a floor area that can be acted upon by a striking device, in particular by a striking pin, of the firearm.

The dummy cartridge is designed as a snap cap dummy round, for example, and designed to reduce the mechanical stress on the impact device that may arise during dry-firing exercises. The flexible or deformable formed Bodenbe rich of the dummy cartridge is typically where the primer is located in live ammunition. The flexible or deformable bottom area dampens the movement of the striking device, in particular the striking pin, in order to avoid mechanical damage.

In embodiments, the dummy cartridge is gebil det at least in the acted upon by the impact device bottom area made of plastic.

In embodiments, the dummy cartridge is a dummy of a central fire cartridge. In alternative embodiments to this, the dummy cartridge is a dummy of a rimfire cartridge. In embodiments, an end piece is arranged at the distal end of the display element, which is designed to protrude from the end of the barrel of the fire weapon. The end piece clearly shows that the firearm with the display and / or safety device is not in a ready-to-fire state.

In refinements, the end piece has an essentially cylindrical shape. An outer diameter of the end piece is larger than an inner diameter of the barrel of the firearm so that it cannot be inserted into the barrel of the firearm.

The end piece indicates that it is safe to use the firearm, especially in the context of dry-firing exercises. In preferred refinements, the end piece is additionally visually specially marked or highlighted by means of coloring.

The invention also relates to the firearm described above, in particular a handgun, with a display and / or safety device of the type described above.

The display and / or safety device described above is used as intended to display or identify an uncharged or not-ready state of the firearm, in particular a handgun.

The use of the display and / or safety device relates in particular to the display of the uncharged state during dry-firing exercises. The display and / or safety device is specially adapted for this purpose, since no means are used to secure the firearm which act on the trigger mechanism of the firearm. In other words, the firearm with the solid display device can be actuated and used in a conventional manner, in particular a trigger of the firearm can be actuated and triggered in the context of dry-firing exercises.

The invention also relates to a method for displaying an uncharged state of a firearm, in particular a firearm used for dry-firing exercises. The firearm has a cartridge chamber and a barrel having a barrel length. The procedure comprises at least the following steps:

- Introducing a dummy cartridge with a distal and a proximal end in the cartridge chamber of the firearm;

- Imports of a display element extended along a central longitudinal axis into the barrel of the firearm in such a way that a proximal end of the display element points in the direction of the distal end of the dummy cartridge inserted in the Patronenkam mer and at least one distal end of the display element protrudes from the barrel at the end;

- Attaching the proximal end of the display element inserted into the barrel at the distal end of the dummy cartridge in such a way that at least the distal end of the display element attached to the dummy cartridge protrudes from the barrel at the end.

In embodiments, the display element is rotated when attaching the proximal end of the inserted in the barrel display element at the distal end of the dummy cartridge at least over an angular range around the central longitudinal axis relative to the dummy cartridge. The fastening means suitable for fastening the display element on the dummy cartridge are designed, for example, as screw or bayonet connections.

The invention is explained in more detail below also with regard to further features and advantages using the description of exemplary embodiments and with reference to the accompanying schematic drawings. Show it

FIG. 1 shows, in a kind of exploded view, the components of a display and / or safety device 1 and a firearm 10. In the exemplary embodiment shown, the firearm 10 is designed as a short weapon, in particular as a pistol. The display and / or safety device 1 is designed to put the firearm 10 in a non-feuerbe riding state and to secure it in this sense. The display and / or safety device 1 is also designed to visibly indicate to the outside that the firearm 10 is in a non-ready-to-fire state. Such a display signals to the user or other persons, for example, that the firearm 10 can be used safely in the context of dry-firing exercises. The display and / or safety device 1 has a two-part structure with two components that can be releasably fastened to one another. The first component is a dummy cartridge 2 which is designed to be introduced into a cartridge chamber 12 of the firearm 10 to be secured. The dummy cartridge 2 has an external shape which essentially corresponds to the shape of regular ammunition which is usually fired by means of the firearm 10. The dummy cartridge 2, however, has neither a projectile nor an ignition and / or propellant charge and is, for example, partially or completely formed from a plastic material in embodiments.

The dummy cartridge 2 is designed for example in the form of a snap cap dummy round, which is elastically and / or deformable in a bottom area 4, which can be acted upon by a striking device, in particular firing pin, of the firearm 10 . For example, the dummy cartridge 1 in the bottom area 4 is at least partially made of a relatively soft material, in particular a plastic, in order to at least partially cushion the force of the impact device when the trigger of the firearm 10 is triggered, and so in particular material fatigue in the event of repeated Ge need to counteract the firearm 10 secured by means of the display and / or safety device 1 as part of dry-firing exercises.

The dummy cartridge 2 is in the exemplary embodiment shown in the drawing figures and is not to be understood as restrictive, a dummy of a central fire cartridge. The flexible and / or deformable bottom area 4, which can be impacted by the striking device of the firearm 10, is located in the center in the area of the central longitudinal axis M.

In other embodiments, the firearm 10 is designed for rimfire ignition. In such designs, the dummy cartridge 1 is a dummy of a rimfire cartridge. In such designs, it is flexible and / or deformable bottom area 4 of the dummy cartridge 2, which can be acted upon by the striking device of the firearm 10, arranged offset with respect to the central longitudinal axis M at the edge.

The dummy cartridge 2 has a proximal end 21 directed in the proximal direction P when the display and / or safety device 1 is used as intended, and a distal end 22 directed in the distal direction D. The bottom area 4 of the dummy cartridge 2 is located at the proximal end 21 of the dummy cartridge 2. At the opposite distal end 22 and at a proximal end 71 of a längli chen display element 7, corresponding fastening means 5, 6 are arranged, which are used to fasten the display element 7 to the In particular, the dummy cartridge 2 already inserted in the cartridge chamber 12 of the firearm 10 is used.

In the illustrated embodiment, the fastening means 5, 6 are designed as a screw connection. In the distal end 22 of the dummy cartridge 2, an internal thread 51 is introduced, into which an external thread 61 of the display element 7 can be screwed.

In other configurations, other fastening means, such as, for example, a bayonet lock, are provided for fastening the display element 7 to the dummy cartridge 2.

The display element 7 has an elongated shape extending along a central longitudinal axis M he. The external thread 61 extends in the form of a type of threaded rod 62 over a large part of the axial length of the display element 7, in the illustrated and non-restrictive exemplary embodiment in particular over approximately 80% of the axial length of the display element 7. At the distal end 72 of the display element 7, an essentially cylindrical end piece 8 is attached, which in the assembled state (cf. in particular FIG. 2) protrudes at the end from a barrel 13 of the firearm 10. The end piece 8 is highlighted in embodiments by a corresponding color scheme to make it clear that the firearm 10, on which the display and / or safety device 1 is mounted, is not in a ready-to-fire state, and in particular in the context of dry -Firing exercises can be used safely.

The end piece 8 is non-rotatably connected to the threaded rod 62. The end piece 8 can in particular be gripped by a user in order to rotate the display element 7 about the central longitudinal axis M relative to the dummy cartridge 2. In this way, the external thread 62 of the display element 7 in particular can be screwed into the internal thread 51 of the dummy cartridge 2.

Figure 2 shows the display and / or safety device 1 in the assembled state. The firearm 10 is shown transparently in FIG. 2, in particular to illustrate the position of the components of the display and / or safety device 1 arranged within the firearm 10.

The dummy cartridge 2 is located inside the cartridge chamber 12. The display element 7 is screwed into the distal end 22 of the dummy cartridge 2 at the end. The display element 7 has an axial length along the central longitudinal axis M which is greater than a barrel length L of the barrel 13. The barrel length L is measured in the context of this description from the distal end 22 of the dummy cartridge 2 to the distal end 14 of the barrel 13 . The end piece 8, the outer diameter of which is slightly larger than the inner diameter of the barrel 13, thus protrudes in the distal direction D in the mon-oriented state in front of the barrel 13. FIG. 3 illustrates a method for displaying an uncharged state of a firearm 10, in particular during dry-firing exercises. The dummy cartridge 2 is first introduced like a dog into the cartridge chamber 12, for example with the slide 15 withdrawn. In other Ausgestal lines, the dummy cartridge 2 is loaded into a magazine of the firearm 10 and transported into the cartridge chamber 12 by means of the regular conveying mechanism of the firearm 10.

In a subsequent step, the display element 7 is inserted with its proximal end 71 first into the distal end 14 of the barrel 13 and is attached to the dummy cartridge 2 by a rotary movement about the central longitudinal axis M. The display element 7 is longer than the barrel length L, so that at least the end piece 8 protrudes distally from the barrel 13 in order to indicate that the firearm 10 cannot be fired.

The display element 7 is made in configurations, as illustrated schematically in particular in FIG. 4, at least in regions, in particular in the region of the threaded rod 62, from a material that can be cut, in particular plastic. The display element 7 is designed to be shortened to the barrel length L of the firearm 10, for example with a knife or scissors, in particular such that the end piece 8 protrudes from the barrel 13 and is more or less flush with it.

The display and / or safety device 1 described above is particularly for use for Flandfire weapons, so fen for handguns, such as pistols or revolvers, as well as for long weapons, such as rifles or shotguns, rifles, carbines, assault rifles or Maschi nenpistolen - if these to be counted as long guns - provided. The firearm 10 identified with the aid of the display and / or safety device 1 relates, for example, to a self-loading weapon, a single-action weapon, a single loader, a repeating weapon, a semi-automatic weapon or a fully automatic weapon. The firearm 10 can be, for example, a pistol, a machine pistol or a revolver. The display and / or safety device 1 for the firearm 10 is provided, for example, for exercises, in particular dry-firing exercises, and is used, for example, when training private individuals, military units or personnel of a security authority, in particular police authorities or law -Enforcement authority and / or bodyguards in dealing with firearms. In other cases, the firearm 10 is a hunting weapon.
