DETAILED DESCRIPTION

[0048] In FIG. 1, a drive 1 for a breechblock 2 of a weapon system 3 is shown schematically.

[0049] Drive 1 is, for example, an external drive which, in this embodiment, is formed of a chain 1.1 and a motor. Chain 1.1 is in turn guided as a round guide 4 around four sprockets 1.2 within a housing 5. Drive 1 has at least two drive cams 17.

[0050] Dwell times of a breechblock 2 to be conveyed by breechblock drive 1 are defined in the front area, as seen in the firing direction, i.e., between the two front sprockets 1.2, as well as in the rear area, between the two rear sprockets 1.2. The length of chain 1 between front sprockets 1.2 and rear sprockets 1.2 is determined by the caliber of weapon system 3. In these sections of chain 1.1, breechblock 2 of weapon system 3 is taken from a front to a rear position or from a rear to a front position within the scope of weapon functioning. Drive 1 is thus responsible for the general weapon functioning.

[0051] In the present exemplary embodiment, breechblock 2 is formed by a breechblock carrier 6 and by a breechblock head 7. Breechblock head 7 is carried by breechblock carrier 6. Breechblock head 7 comprises, in a known manner, an extractor groove 25 which is used to remove a cartridge case. Drive 1 can be mechanically coupled to breechblock carrier 6.

[0052] Breechblock 2 can be locked to and unlocked from a weapon barrel via its breechblock head 7. The locking is realized by a chamber sleeve, which in practice is connected to the weapon barrel and usually to a recoil damper.

[0053] Drive 1 is accommodated in a housing 5. Housing 5 can be part of a weapon housing 5′. Alternatively, this can also be an independent housing 5 of drive 1. The structural variant has the advantage that housing 5 together with drive 1 forms a drive module. As a result, the drive module can be interchangeably attached to the weapon housing as a modular unit.

[0054] Two guides or round rods 8 are introduced preferably over the entire length of housing 5. These are guided in bores 9 of breechblock carrier 6. Guides 8 are used to enable a free movement towards drive 1 for the expected weapon recoil when breechblock 2 is locked. Round rods 8 can additionally be used for support and stabilization during the conveying of breechblock 2 within the weapon functioning.

[0055] Breechblock carrier 6 has a cam track 10 in which a control pin 11 of breechblock head 7 is guided.

[0056] A control cam 12 is integrated on the side of housing 5 (5′) in the path of the weapon recoil. FIG. 2 shows some details from FIG. 1 in more detail. For this purpose, breechblock carrier 6. As can be clearly seen, four slides 13, 14, 15, 16 are provided which are structurally incorporated in breechblock carrier 6. Slides 13, 14, which can be locked against one another and are controlled in the area of a drive cam 17 of chain 1, bring about the forward and reverse movement of breechblock 2 during weapon functioning. Drive 1 disengages automatically at the end of the forward or reverse movement of breechblock carrier 6. For this purpose, a control shaft 18 is provided, which is also structurally integrated in breechblock carrier 6. Control shaft 18 operates slide 13, in order to couple breechblock carrier 6 to drive 1, or slide 14 in order to separate it from drivel.

[0057] Housing 5 (5′) preferably has a central elevation 19 which is run longitudinally within housing 5. Elevation 19 comprises detent points 20, 21 which define the stopping at the rear and at the front for breechblock 2.

[0058] FIG. 3 shows some components from FIG. 2 in more detail. Control cam 12 and slides 13-16 can be clearly seen. Control cam 12 interacts with slide 16 during the weapon recoil. Control cam 12 has a front slope 12.1 and a rear ramp 12.2.

[0059] Control shaft 18 for its part interacts with a control plunger 22 which is disposed below housing 5 (5′) and which is actuated by a control flap 23 mounted below housing 5.

[0060] FIG. 4 shows the components from FIG. 3 in a front perspective view.

[0061] FIG. 5 shows breechblock carrier 6 with breechblock head 7, wherein breechblock 2 is opened and is in its loading position (rear position).

[0062] The function will be described in more detail with the use of the figures:

[0063] During firing, breechblock 2 is separated from drive 1 and disengaged from it. With the weapon recoil, a weapon barrel and breechblock 2, i.e., breechblock carrier 6 and breechblock head 7, are accelerated opposite to the firing direction.

[0064] During the recoil of the recoiling masses, slide 16 passes over control cam 12 and pushes it away downwards. After the reversal point of the weapon recoil during the forward motion of the recoiling masses, slide 16 is guided along ramp 12.2 and thereby pressed out of a locking groove 7.1 of breechblock head 7. Locking groove 7.1 is preferably provided at the rear end of breechblock head 7. Breechblock head 7 is released. Breechblock carrier 6, in contrast, is held in place. Breechblock head 7 with the weapon barrel, the chamber sleeve, and, if applicable, the recoil damper, if present, is pulled further forward in the forward motion. At the same time, breechblock head 7 is caused to rotate along cam track 10 until the “unlocked” state is reached. The chamber casing and the weapon barrel move further forward without breechblock head 7 until both are in the starting position (end position).

[0065] With the unlocking, a cartridge case is also pulled out of the weapon barrel, at least to some extent. This is done via extractor groove 25 on breechblock head 7, which engages in a groove in the cartridge bottom of the cartridge case.

[0066] During the forward motion of the recoiling masses, control plunger 22 is additionally pushed upwards via the control flap or control ramp 23. Slide 14 located above control plunger 22 is pushed upwards. Slide 13 is controlled downward via control shaft 18.

[0067] A drive cam 17 of drive 1, which is decoupled from breechblock carrier 6 at this point in time and continues to run in the weapon functioning, runs into slide 13 which is controlled downwards. Drive 1 is now connected to breechblock carrier 6 via slide 13 for the actual weapon functioning.

[0068] Breechblock carrier 6 and breechblock head 7 are then moved backwards into the “open position” by coupled drive 1 within weapon system 3 until the position for presenting the next cartridge is reached. In this position, breechblock carrier 6 stands still and is disengaged or uncoupled from breechblock drive 1.

[0069] When the cartridge is inserted, breechblock carrier 6 is held in place in housing 5 (5′). This retention is supported by the rear detent point 20. Breechblock head 7 is locked in the “open position” by slide 15 during weapon functioning.

[0070] If there is a new cartridge in front of breechblock 2, breechblock carrier 6 is connected to drive 1 again. For this purpose, slide 14 is controlled downwards, which is possible by a similar construction at the rear end of housing 5, 5′, similar to the mimic 18, 22, 23.

[0071] Breechblock carrier 6 with breechblock head 7 is moved into the front position via drive 1. In so doing, they transport the cartridge into a cartridge chamber in the gun barrel. In the front position, breechblock 2 is locked to the weapon barrel or the chamber case.

[0072] When breechblock 2 is locked, the chamber sleeve, breechblock head 7, and breechblock carrier 6 are locked against one another by slide 16, but are freely movable towards drive 1 for the expected weapon recoil on round guides 8.

[0073] In addition, a firing pin is cocked during the locking process.

[0074] When drive 1 is disengaged, the shot is fired or the weapon recoil is waited for. In this regard, weapon system 3 can be operated both selectively as a single shot and in continuous fire.

[0075] The cycle starts again with the onset of the weapon recoil.

[0076] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
