Abstract

The invention relates to a mass-lockable weapon locking system (1) having a locking piece (3) that can be movably mounted in a receiver housing (2) of a corresponding weapon and an elastic locking device (5) that acts on the rear of the locking piece (3). To ensure that the locking of powerful munition does not involve any significant weight increase of the locking device (5), a gas spring is used as the locking device (5) according to the invention. To this end, the receiver housing (2) comprises a pneumatic cylinder (4) extending in the direction of the barrel bore axis (100) of the weapon, in which pneumatic cylinder (4) the locking piece (3) is moveably arranged as a sliding piston, wherein the cylinder region (5) that extends at the rear behind the locking piece (3) and is filled with a gas, forms the locking element that acts as a gas spring.

Description

 DESCRIPTION

Mass lockable weapon locking system

The invention relates to a mass-locking weapon locking system with a closure part that can be displaceably mounted in a closure housing of a corresponding weapon and an elastic closing element acting on the rear part on the closure part.

In automatic or semi-automatic weapons with mass lockable closure system, the weapon barrel of the corresponding weapon is closed at the rear by a closure part, wherein the closure member slidably disposed in a nrohr to the weapon axially subsequent closure housing of the weapon and an elastic closing element (Vorholer), in which it usually is an expensive special spring (closing spring), is acted upon (see, for example: Rheinmetall "Weapon Technique Paperback", Dusseldorf, 7th Edition 1985, pages 248 f.).

To shoot powerful ammunition you need in each case a strong closing spring in the known mass-locking locking systems. This leads when using long closing springs to increase the weight of the corresponding weapon or the spring characteristic of the respective closing spring must have a steep increase in force. In addition, the closing springs are exposed in the known closure systems environmental influences and can easily pollute.

The invention has for its object to provide a mass-locking locking system, which ensures a high reliability and which is also connected for firing high-performance ammunition with no significant increase in weight of the Vorholers. This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.

The invention is based essentially on the idea to use as a prefetcher for the closure part no mechanical closing spring, but a gas spring.

For this purpose, the closure housing comprises a pneumatic cylinder extending in the direction of the bore axis of the weapon, in which the closure part is displaceably arranged as a sliding piston, the cylinder area extending behind the closure part and filled with a gas forming the closing element acting as a gas spring, i. stores the energy required for the Vorholvorgang.

In order to be able to take into account changes in the ambient air pressure and / or the ambient temperature, a path-dependent adaptation of the characteristic curve of the gas spring can preferably be achieved by arranging at least one throttle opening in the cylinder wall of the pneumatic cylinder, through which part of the rearward and / or backward opening Forward movement of the closure member in the Vorholzylinder compressed gas can escape to the outside.

Advantageously, it may be provided that a plurality of throttle bores are arranged in the cylinder wall of the pneumatic cylinder and that an annular gap remains between the outer wall of the closure part and the inner wall of the pneumatic cylinder, wherein at least one of the throttle bore is arranged in the cylinder wall in the region of the annular gap.

The throttle bores may each be provided with an adjusting device such that they are opened or closed depending on the direction of movement of the closure part, the pressure level or the distance traveled by the closure part in a predetermined direction (flow, return).

The gas for the gas spring may be air.

Further details and advantages of the invention will become apparent from the following, with reference to figures explained embodiments. Show it: 1 shows the longitudinal section of a schematically represented weapon locking system according to the invention with a closure part arranged in a weapon housing in its starting position;

2 shows the closure system shown in Figure 1 after firing at the end of the return of the closure part and

3 shows the closure system shown in Figure 1 during the flow to its starting position.

In FIGS. 1 to 3, denoted by 1 is a mass-locking weapon locking system, which comprises a closure housing 2, which adjoins the rear of the cartridge chamber of a weapon barrel (not shown).

In the closure housing 2 is a in the direction of the tube bore axis 100 of the weapon barrel (Fig.1) axially displaceable closure part 3, which also contains the reasons not shown for clarity, required for firing and for removing the cartridge after firing elements.

According to the invention, it is now provided that the closure housing 2 and the closure part 3 form a pneumatic cylinder 4 (pneumatic recuperator), wherein the closure part 3 is designed as a sliding piston and air is used as the gas.

The rear side of the closure part 3 extending, and filled with air cylinder area 5 (storage cylinder) of the pneumatic cylinder 4 forms a closing element acting as a gas spring.

In order to adapt the spring characteristic of the gas spring to the conditions of use of the weapon closure system 1, a plurality of throttle openings 7 are provided in the side wall 6 of the closure housing 2, through which a portion of the compressed air can escape from the closure housing 2 to the outside for pressure relief during the displacement of the closure part 3 , In this case, some throttle openings 7 are also arranged in the region of an annular gap 8 between the outer surface 9 of the closure part 3 and the inner surface 10 of the closure housing 2. The throttle openings 7 can be opened or closed with the aid of adjustment devices, not shown, depending on the direction of movement of the closure part 3, the pressure level or the path-dependent of the closure part in one direction (flow, return).

Hereinafter, the operation of the weapon closure system 1 according to the invention will be discussed in more detail with the aid of FIGS. 1 to 3:

In the illustrated in Figure 1 starting position of the closure system 1, the closure member 3 is in its forward position and is fixed to a housing stop 11 by a mechanism, not shown. In the storage cylinder 5 is ambient air.

When firing a (not shown) cartridge, the propellant charge gases act on the impact bottom 12 of the closure part 3. This leads to an acceleration of the closure member 3 against the weft direction (in Fig.2 with the arrow 1 10 indicated) and thus to a movement of the closure part. 3 in the return direction.

The air in the storage cylinder 5 is compressed and the pressure in the storage cylinder 5 is increased, so that the closure part 3 is decelerated in its movement in the return direction.

If desired, can be done by the annular gap 8 and the throttle openings 7 in the side wall 6 of the closure housing 2, a pressure relief by escape of a portion of the compressed air from the closure housing 2.

After the return of the closure part 3 has been completed (FIG. 2), the closure part 3 is again displaced in the weft direction by the pressure force of the compressed air acting on its rear side 13 facing the storage cylinder 5 (FIG. 3) until the closure part 3 returns to its starting position has reached (Fig.).

Since in the Vorholvorgang an increase in volume of the storage cylinder 5, the internal pressure of the closure housing 2 may already correspond to the external air pressure before the closure part 3 has reached its starting position. In this case, in the last region of the feed, the internal pressure of the storage cylinder 5 can be reduced below the ambient pressure of the air sink.

Nevertheless, even in such a case, the closure part 3 due to the inertia of the sealing compound and optionally by an additional flow device (not shown) reaches its starting position (Figure 3). In addition, after the initial position has been reached, the ambient air flows back into the storage cylinder 5 until the internal pressure in the storage cylinder 5 corresponds to the external air pressure.

The invention is of course not limited to the specific embodiment shown. Thus, it is not absolutely necessary for the pneumatic cylinder to act on the closure housing itself, but it may also be a separate cylinder arranged in the closure housing and connected thereto, in which the closure part is displaceably arranged as a sliding piston.
