Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a double loading prevention device in a cartridge feeder (86) for automatic weapons, where the cartridge (12) is fed from two sides, and the cartridge (12) is fed from one side. A first conveying device (10) for feeding the cartridge (12), a 2111th feeding device (11) for feeding the cartridge (12) from the other side, and a cartridge support for the gun barrel (67). (84); a device for ejecting the cartridge (12) or the cartridge (88) from the cartridge support (84) of the gun barrel (67); a device for checking whether the cylinder (12) or the bullet (88) has been ejected; and a first or 21st feeding device (10,
11) and a device (42) for shutting off the drive (89).

(Prior Art) A known device of this type (West German Patent Publication No. 20455
No. 83), in an automatic firearm equipped with a gun barrel having a cartridge chamber, there is a loading device for inserting the cartridge into the loading chamber of the gun barrel. On the side of the loading chamber there is an exit opening for the cover of the closed cartridge.

This known device has a device which responds to the ejection of a cartridge into the trajectory of the ejected cartridge in order to initiate the operation of said loading device, so that an empty cartridge of the preceding cartridge is loaded. When the cartridge is ejected, the cartridge is forced into the loading chamber. The device has a baffle that is ejected and deflects the cartridge from the firearm. This deflector plate can be pivoted by the ejected cartridge in order to start the operation of the loading device.If the preceding cartridge is still in the loading chamber, this known device allows the deflection plate to move into the gun barrel. cannot enter the loading chamber of the gun, but check whether an empty cartridge or a leading cartridge has been ejected from the gun barrel.

Devices for this have the disadvantage of a relatively slow response.

The problem to be solved by the present application consists in particular in the creation of a double-loading prevention device which prevents a cartridge from being accidentally pushed in before the next cartridge is withdrawn from the magazine of a gun barrel. This results in the next cartridge hitting and igniting the preceding cartridge in the magazine with its tip. Such ignition of the cartridge when the obturator opens is dangerous to defense and can lead to destruction of the firearm.

The double loading prevention device that should solve this problem is the ammunition M (1

7) is not ejected from the cartridge support (84), this is solved by not driving any of the reconveying devices (10, 11) in the neutral position.

(Example) (Structure) According to FIGS. 1 and 4, the ammunition cartridge feeding device has two star-shaped carriers 10.11, and the star-shaped carriers supply the ammunition barrel 12 to the firearm 13. , the right star carrier 10 moves the cartridge 12 from the right in the direction of the arrow and the left star carrier 11
supplies the cartridge 12 to the firearm 13 from the left in the direction of arrow B. As soon as the cartridge 12 is in the position shown in FIG.
A lever 14, only partially shown, pushes into the gun barrel, only the axis 15 of which is shown here. Star-shaped carrier 10
．． 11 is driven by the rear seat of the gun barrel via a drive in a manner not shown in detail. Since the two cartridges 12 are not fed into the gun barrel 15 at the same time, it is only necessary that one or the other star carrier 10 or 11 be driven. According to FIG. 1, therefore, two clutches 16.17
These require that, via the pivot lever 18, when one clutch is engaged, the other clutch is disengaged. This pivot lever 1'8 is mounted pivotably about an axis 19. In the central position shown, both clutches 16.17 are disengaged and the star carrier 10.11 is driven, so that the cartridge 1 can be accessed from both the right and the left.
2 is not supplied. However, the double-legged carrier 10 or 11
When one of them is input, the other star-shaped carrier 11 or 10
is prevented from rotating. The double-legged carrier 10.11 is pivotably mounted in the housing 20. This housing has two different pins 21, one of which is represented in FIG. This pin 21 is pushed into the hole 20 of the star carrier 11, so that the star carrier 11 is prevented from rotating. This pin 21 is fixed to a sliding member 23, and the sliding member is movable by a lever 24 having two arms. The two-armed lever 24 enters this sliding member 23 with one arm and into the slider 25 with the other arm. By means of this slider 25 the already mentioned swivel lever 1
8 is pivoted. As will be described later, the slider 25 serves to insert and disengage the star-shaped carrier 11, and when the pin 21 is engaged and disengaged by the slider 25, it is inserted into the hole 22 via the two-armed lever 24 and via the sliding member 23. pushed into.

According to FIG. 3, the clutch 16 consists of two clutch halves 2
6.27, each with one tooth.

One clutch half 26 is rigidly connected to the star-shaped carrier 10, and the other clutch half 27 is movable.
It is fixed to the drive shaft 31 in a non-rotatable manner. Behind this clutch half 27 is a ring 28 which is likewise movable but is fixed non-rotatably on the shaft 31. The driver 32 grips the second clutch half 27 . Between the second clutch half 27 and the ring 28 there are a number of coil springs 33, only one of which is shown in FIG. The driver 32 is fixed to the slider 25 already mentioned.

To engage the clutch, the slider 25 is moved in the direction of the arrow in FIG.
64, thereby causing the teeth 29 on the end face to abut against each other.
30 interlock with each other. When the tooth hits the teeth of both teeth 29.30, the coil spring 33 is compressed and the teeth of both teeth 29.30
As soon as they are properly engaged, they are stretched.

For the movement or actuation of the slider 25, the batten 34 is fixed on the slider 25 on the one hand and on the actuating rod 35 on the other hand.

According to FIG. 2, this actuating rod 35 is connected to a joint 36.
It is connected to the angle lever 37 via.

This angle lever 37 is rotatably supported around a shaft 38 having a rectangular cross section. Angle lever 37's other arm 3
9 is engaged in the recess 40 of the slider 41. The slider 41 can be locked in three different positions by a switching locking device 42. In the illustrated central position of the slide 41, both clutches 16, 17 are engaged and disengaged, and the cartridge 12 is not fed from either the right or the left. The cam 43 can be locked in one of the three recesses 440 of the slider 250 by the electromagnet 45. The spring tends to hold the slider 41 in its neutral position.

According to FIG. 4, the cartridge 12 is moved from the barrel 1 by the lever
Pushed to 5. Since the lever 14 grips the bottom of the cartridge 12 from below, there is a risk that the cartridge 12 will be slid upwards by the lever 14. Therefore, the cartridge 12 is
It is necessary to guide it upwards. rail 46
is fixed to a pivotable lever 47 which is pivotably mounted about an axis 90. This rotation possibility is 12 cartridges.
As is clear from both positions, the cartridge is located on the star-shaped carrier 10.
or 11 into the pushing position from the right or from the left, the cartridge 12 according to FIG.
It is necessary to reach below 6. The lever 47 has two arms 48, each of which carries a spring-loaded shaft 49 (FIG. 5) at its lower end. The upper end of the shaft 49 rests on the slider 41 according to FIG. 5, so that the lever 47 is not pivoted to the left or to the right in the illustrated position of the slider 41, so that the cartridge 12 is not fed at all. I can't. Each shaft 49 has one coil spring 5
0, the spring presses the shaft 49 against the arm of the pivot lever 47. In addition to the recess 44 described above, the slider 41 has two other recesses 51. When the slider 41 is moved to the right or left, one or the other shaft 49 is engaged in one or the other of the recesses 51, and the pivotable lever 4
7 can be pivoted to the right or to the left to release the cartridge from the right or from the left. Groove 5 of slider 51
The two locking pins 52 entering 3 attempt to hold the slider 47 in the neutral position shown. According to FIG. 7, there is an overload clutch inside the star carrier 10, which is constructed as follows. Clutch 1 shown in Figure 3
6, the clutch half-off 26 is fixed to a short shaft 54 (FIG. 7) by a vertical groove 55. The shaft 54 is rotatably mounted in a bushing 56 screwed into the housing 57 of the star carrier 10. Two star wheels 58, 59 of the star carrier 100 are fixed to this housing 57. The shape of this star wheel 58,59 is clear from FIG. The shaft 54 is rotatably connected via two star wheels 60, 61 to an axially movable shaft 62. ring spring 63
attempts to press the star wheels 60, 61 of both shafts 54 and 62 together. The shaft 62 has a longitudinal groove 64 at the end opposite the teeth 61 on the end face, the longitudinal groove being connected to the housing 57 of the star-shaped carrier 10.
are connected to corresponding longitudinal grooves 65, so that the axis 62 is prevented from rotating inside the housing 57 and is only movable in the axial direction.

The star carrier 10 is thereby driven by the clutch 16 (FIGS. 1 and 3) via the shaft 54 via the star wheel 60, 61 and the shaft 62. If the torque is too large,
The oblique surface 66 of the end face 60 exerts an axial movement of the shaft 62 against the force of the ring spring 63, so that damage to the star carrier 10 is avoided.

According to FIG. 6, the cartridge 12 supplied by the cartridge supply bag W86 of the present invention is pushed into the gun barrel 67. When the cartridge 12 is pushed into the gun barrel 67, the shoulder 68 of the cartridge 88 abuts against the detection pin 69. This detection pin 69 abuts on a lever 70 that abuts on a lever 71 of the two arms. A shaft 72 for operating an electric switch 73 is supported on the two-armed lever 71. This electric switch 73 activates the switching lock 42 shown in FIG. Upon actuation of the switching lock, according to FIG. 2, the cam 43 is returned, whereby the slide 41 can be moved into a neutral position, in which the cartridge 12 is not fed from either the right or the left.

According to FIG. 5, in the neutral position of the slider 41, the swing lever 47 is also rotated in its neutral position, and according to FIG. prevent it from being supplied to

According to FIG. 6, the gun barrel 67 is in its forward position under the action of a not-illustrated rear seat spring, which is compressed during the rear seat of the previously fired cartridge and then released again. Gun barrel 67 is fixed in housing 74, which is movably supported within firearm housing 75. In this movable housing 75 the cartridge 12 is in its closed position after being pushed into the gun barrel 67 . This pushing device 77 is fixed to a movable housing 74 and has a carriage 78 with a cam 79. A two-armed lever 80 serves for the movement of the carriage 78. This two-armed lever 80 is pivotably supported in the housing 74 and uses one of its arms to open the slit 80 of the carriage 78.
Enter 1. In the other arm, the lever 80 has a roller 82 which controls the firearm housing 75 in a fixed position.
It is guided through the groove 83. Depending on the shape of the control groove 83, during the forward movement of the housing 74, the two-armed lever 80 is pivoted counterclockwise and the carriage 78 is moved from the rear to the front. At this time, the cam 79 of the carriage 76 abuts against the bottom of the cartridge 12, thereby accelerating the cartridge and pushing it toward the barrel 6.
7 into the cartridge support portion 84. In FIG. 6, the cartridge 12 is completely within the cartridge support 84 of the gun barrel 67. The carriage 78 is movably guided in a guide 85 in the movable housing 74 .

Ammunition cartridges 12 are fed by a cartridge feeder 86.

The cartridge feeding device 86 has star wheels 58,59 by which the cartridges 12 are fed from the right side, ie transversely to the firing direction. There is also a guide rail 46 between the castors 58, 59, on which the cartridge support 8 of the gun barrel 67 is moved by means of a cam 79 of the carriage 78.
Pushed into 4. The insertion device 77 is not an object of the present invention and will not be described in detail.

(Action of invention) The double loading prevention device functions as follows.

The cartridge 12 is in the automatic weapon's loading chamber 84 and the firing pin 8
Suppose that it is stabbed by 7. The projectile is ejected forward by the emitted gas, and the rear seat force generated thereby moves the gun barrel 67 rearward together with the movable housing 74, tensioning a rear seat spring (not shown). When rearing the gun barrel, the following occurs:

1. The wedge-shaped closure device 76 is moved from the closed position to the released position.

2. The empty cartridge 88 is ejected from the cartridge support 84 of the gun barrel 67.

3. The carriage 78 of the cartridge feeder 77 is moved from its forwardmost position to its rearmost position.

4. The cartridge feeding device 86 is driven by the rear gun barrel 67 and the movable housing 74, the star carrier 10 or 11 being rotated and the cartridge 12 being fed into the firearm. The drive, which is actuated by the rotational speed of the star carrier 10 or 11 on the one hand, is not the object of the present application and will not be described in detail.

However, if the device for the ejection of an empty cartridge is in question and an empty cartridge 88 is loaded into the cartridge support 84 of the gun barrel 67, the detection bin 69 is in its uppermost position.

The lever 70 and the two-armed lever 71 are not pivoted, and the shaft 72 is not moved. Switch 73 is thereby not activated. Switching lock device 242 connected to Sui and Tsuchi 73
cam 42 (FIG. 2) is not released; this means that cam 42 (FIG. 2)
3 is not held by the electromagnet 45 of the device 42 and is not inserted into any recess 44 of the slider 41. The slider 41 is moved to its neutral position by the action of a spring (not shown). Via the angle lever 37, the actuating rod 35 and the batten 34, both the slider 25 and the pivot lever 18 are pivoted into their neutral position.

Both clutches 16, 17 are disengaged and the cartridge 12 is not fed. The slider in the neutral position (FIG. 5) prevents the pivot lever 47 from pivoting via the shaft 49, thereby allowing the fourth
The illustrated rail 46 also prevents the feeding of further cartridges 12. If both clutches 16, 17 are to be engaged, the overload clutch 60 integrated in the star carrier 10 or 11
~63 prevents damage to the cartridge feeding device 86 (.

When the ammunition barrel 12 is pierced by the firing pin 67, the ammunition barrel 12 is not ignited, and the ammunition barrel support portion 84 of the gun barrel 67 is treated as an unexploded ordnance.
, the cartridge must be removed by hand. For this purpose, there is a manual chuck device (not shown).
This device allows the gun barrel 67 to be returned against the force of the rear seat spring. Gun barrel 67 with manual chuck device
During rearing, the same steps as described occur when the gun barrel is reared by the rearing force of the radiant gas. In this case, it is not an empty cartridge, but rather a cartridge that is "ignited..."
is dispensed, in which case double loading prevention is particularly important.
