Description

DESCRIPTION

Function control for feeding an ammunition into a weapon barrel

DE 10 2006 022 622 A1 describes a linear feed of the ammunition into a weapon barrel or cartridge chamber, which has a control link used for function control in the horizontal plane parallel to the path of a closure of the closure weapon leading in a straight line. This functionally cooperates with a so-called also in the horizontal plane drive link for guiding a connected to the closure means. The drive link is integrated in a movable slide, which in turn is adjusted by a universal design drive. For a locking of the closure further comprises a locking link is provided, which is preferably integrated together with the drive link in the movable slide. In this locking link can engage a bolt preferably a weapon side arranged locking ring. This bolt in turn then moves the locking ring. Within the co-acting control link and the drive link a connecting rod or the like is forcibly guided through the scenes and the slide along these scenes. With this connecting rod, the shutter is moved back and forth.

A use for a drum weapon is neither planned nor possible.

Here, the invention has the object to show a function control for a drum weapon, with a simple feeding of the ammunition can be achieved in a gun barrel.

The object is achieved by the features of claim 1. Advantageous embodiments are listed in the subclaims.

The invention is based on the idea to realize the function control also by means of scenes and in this guided connecting rod. The function control itself includes the feeding of an ammunition into the drum or the respective cartridge chamber and the circuit of a drum for adjusting selbiger. Both connecting rods are operated by a common slide or guided in the scenes of the slider. Located in one of the scenes Thus, the connecting rod, which interacts with a slide switch, in the other backdrop, the connecting rod of the feed is performed. The slide or the scenes integrated therein are preferably divided or at least in two levels, wherein the two levels are mutually adjustable (displaceable). A further division would be possible, but is not considered necessary.

The slide switch or cam of the slide switch of the drum is in turn guided in a switching curve, which is peripherally integrated on the drum. In continuation of the invention can be reduced or minimized by dividing this switching curve, the drum length to the maximum cartridge length. That makes this area smaller.

In a particular embodiment, the drum is housed in a closed housing. In this case, the ammunition is introduced from the front into the chamber of the drum.

Reference to an embodiment with drawings, the invention will be explained in more detail. It shows:

1 shows a part of a weapon in a sectional view with the essential elements for explanation,

2 is a plan view of the weapon,

3 shows a schematic sequence of the drum movement,

4 is an illustration of the drum circuit according to a preferred embodiment,

5 is a sectional view in section A-A of Figure 1 with attached magazine,

6 is an enlarged view of FIG. 5 without magazine,

Fig. 7 shows a preferred embodiment with a spiral magazine in opposite directions to the drum. In Fig. 1 can be seen the parts essential for the explanation of a not otherwise detailed weapon 1 shown with gun barrel 2.

The weapon 1 comprises a drum 3, which is characterized in this embodiment in that it has a closed housing 4. Four cartridge chambers 5 for receiving a munition (21, FIG. 2) that can be fed from the front (P) are preferably integrated into this. Behind the drum 3 is completed by a preferably housing own lid or shock bottom. 6

The drum 3 beisitzt circumferentially a drum circuit in the form of a guide cam 20 and is rotated by a slide switch 7. The special feature in the preferred embodiment in this embodiment is that the drum circuit or the guide curve 20 is divided. For this purpose, the slide switch 7 two cams 8, 9, wherein the rear cam 8 is mounted vertically movable, preferably resiliently. Connected to the slide switch 7 is a connecting rod 10th

If, however, the guide cam 20 is undivided, the slide switch 7 in turn requires only one cam 8.

With these elements functionally via the connecting rod 10 is a further front of the gun barrel 2 integrated and divided into two levels slider 11 with two upper cams 11 a, 11 b and two lower cams 11 c, 11 d connected, the upper cam 11 a and the lower cam 11 c with the connecting rod 10 of the slide valve 7 and the cams 11 b, 11 d with a connecting rod 13 of a feed slide 14 (FIG. 2) for the ammunition 21 work together. The cams 11 a and 11 c and 11 b and 11 d have a comparable with a hockey stick curve guide and complement each other functionally. The upper level of the slider 11 is movable. A plan view of this is the Fig. 2 can be removed.

In particular, with reference to FIG. 3, the sequence of loading or feeding the ammunition 21 of the weapon 1 will be illustrated. Although the weapon 1 is shown here as a self-propelled weapon (gas pressure), another type of drive (driven externally) can also be used. By means of the drive, here a gas piston 22 (alternatively also external drive possible), the upper level of the slide 11 located previously in its starting position (FIG. 3a) is moved to the lower level of the slide 11 (FIG. 3b). With this adjustment, the control cam 11a moves along the connecting rod 10, while the connecting rod 10 itself stops. The connecting rod 13, however, is moved by the control cam 11 b and thus also the Zuführschieber 14. In about the same time reach the connecting rod 10 and the connecting rod 13, the reversal point U in their upper cams 11 a, 11 b (FIG. 3c), the ammunition 21 is fed. Now act the lower, fixed cams 11c, 11d. The feed slide 14 stops because the connecting rod 13 is stored and not moved further, the slide switch 7, however, is moved by the in the control cam 11 a further adjusted connecting rod 10. With taking the common end point E in the lower and upper level, both connecting rods 10, 13 have taken their disfigurement within their switching curves 11a, 11c, and 11b, 11d, the upper level of the slide 11 moves back (Fig. 3d ), the slide switch 7 performs on the cams 8, 9, the drum movement or drum circuit, for example, by 45 ° (four cartridge chamber 5) (Fig. 3e). Reached the connecting rod 10, the end of its lower cam 11c and the reversal point U in its upper cam 11a, the system is in the firing position S. Thereafter, the slide 11 goes back, takes over the connecting rod 13, the feed slide 14 in the so-called starting position and with it in the ignition position with (Fig. 3f).

The process repeats to reload and trigger.

In the preferred embodiment, the drum circuit 20 is provided as a split drum cam. This allows the shortening of the drum 3 on the cartridge length. This embodiment is shown in more detail in FIG. 4, from which both versions can be seen.

The rear resilient cam 8 is in the starting position (no cartridge 21 supplied) in engagement with the rear guide cam 20.1, the front cam 9 is not yet. By moving the slide switch 7 (by connecting rod 10), the cam 8 is guided along this guide curve 20.1. Even before the cam 8 emerges from this, the second cam 9 comes into engagement with the front guide curve 20.2. The movement of the slide valve 8 is now defined by the design of the front guide curve 20.2. In this is for Totpunktverlagerung and avoiding disturbances a so-called manual shift curve H in the form of a slope involved, whereby no dead center can be caused. So that the rear cam 8 does not come out of its guide curve 20. wegungsumkehrung break out, a lateral increase in the guide curve 20.1 is provided.

Before exit of the cam 9 from the front guide curve 20.2 again engages the rear cam 8 in the action, that is, in the rear guide curve 20.1 and takes together with the slide switch 7, the starting position 0 ° - shot release S - a. If a continuous fire is set, the initial position is slightly differentiated from the original starting position further forward (FIG. 4a). This effect can be exploited to counter the current masses to the recoil of the next shot.

With the path of the slider 7 to the rear, the drum 3 is thus rotated by 45 °, with the forward movement of the slider 7, the rotation of the drum 3 is carried by the remaining 45 °. These degrees of rotation necessary rotation of the drum 3 are determined by the number of existing cartridge bearings 5 in a drum, so that would be in a different number of cartridge bearings 5 than the four described, the curve shape of the split guide curve 20 would adjust.

The sum of both guide curves 20.1 and 20.2 to a common drum cam 20, however, would give the simplest variant. In this case, the front guide curve 20.2 would connect seamlessly to the rear guide curve 20.1 and only the one cam 8 would start the common guide curve 20. On the cam 9 can then be dispensed with.

In Fig. 5 is a sectional view in section A-A from Fig. 1, which is shown in Fig. 6 partially enlarged and show advantageous connections to the weapon 1. With 15 storage of the weapon return is characterized, which causes a very simple but effective storage by the shaft integration of the guide rail. Z is the feed position, S is the shot position and A is the ejection position. A magazine 16 stores the ammunition 21 to be supplied. This embodiment does not require a gradual feeding of the ammunition 21 into the firing position, but alternatively a control cam can be integrated between the cartridge feed and the magazine drive, by means of which a clocked feed can be realized.

Fig. 7 shows in a preferred embodiment, the inclusion of a spiral magazine 16 ', which opposite direction to the drum 3 acting causes a torque balance.
