Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is an ammunition supply device for automatic firearms, and is used to supply ammunition for automatic firearms equipped with a magazine in which a cartridge filled with cartridges is movable. Regarding the supply device.

BACKGROUND OF THE INVENTION In such ammunition feeding devices, the commissioning process is such that an empty cartridge is inserted only when the magazine is completely empty, and then the desired number of filled cartridges are inserted. is required. This commissioning is necessary to ensure acceptable functioning of the ammunition feeding device.

Such an operational introduction is not always followed, and even if the magazine is emptied, a filled cartridge is first inserted instead of an empty one, thereby ensuring that the acceptable functioning of the ammunition feeding device is achieved. Occurred when not guaranteed.

OBJECTS OF THE INVENTION The invention consists in creating a device in which insertion of a cartridge is made difficult if there is no cartridge in the magazine. In particular, this blocking device should be designed in such a way that it can be easily integrated into known and existing ammunition feeding devices.
Faced with this difficulty, the inventors conceived that an empty cartridge must be inserted into the magazine in order to release the blocking condition before a filled cartridge can be inserted.

SUMMARY OF THE INVENTION It is an object of the invention that the magazine has a pivotably mounted blocking lever, which is inserted under the action of a spring force when the magazine is empty. A cartridge which enters into the trajectory of the cartridge to be inserted and prevents insertion of the cartridge by its stopper, and which is inserted against the force of a spring when inserting an empty cartridge. can be pivoted out of the trajectory of the magazine, thereby allowing the insertion of a loaded cartridge, with a pivotably mounted blocking lever being mounted about an axis in the magazine; The problem is solved by an automatic firearm ammunition feeding device featuring:

(Example) An example of an ammunition supply device equipped with a blocking device of the present invention will be described based on the drawings.

According to FIGS. 1 and 2, the magazine 10 has a number of cartridge strips 11. Each cartridge belt 11 has seven cartridges 12. As shown by arrow A, insert belt 1
1 is moved downward in the magazine 10 and the cartridge 12 is removed from the lowermost cartridge strip 11 to the left as indicated by arrow B. Finally, as indicated by arrow C, the cartridge 12 which has been pulled out of the lowermost cartridge belt 11 passes from the magazine 10 via a curved duct 13 to a firearm 14, which is only indicated by a rectangle. An endless chain 15 guided around two deflecting rollers 16 and 17 for the movement of the cartridge strip 11
is used. A pawl 18 is pivotally supported on this endless chain 15, and the pawl abuts against the cartridge belt 11 to be moved. Two other endless conveyor chains 19 are provided for the removal of cartridges 12 from the lowermost cartridge belt 11.
and 20 are used, this endless conveying chain being guided around two deflection devices 21, 22.
As is clear from FIG. 2, the endless chains 19 and 20 are tilted diagonally downward, so that when the cartridge 12 comes out of the cartridge strip 11 in the direction of arrow B, the cartridge strip 11 simultaneously moves along the arrow A. can descend in the direction of The resultant force of both movements in the direction of arrows A and B corresponds to this inclination of the endless conveying chains 19 and 20. These two endless conveyor chains 19
and 20, respectively, are fixed to two guide bodies 23 and 24, and the guide bodies are arranged at the end of the cartridge belt 11 in order to take out all cartridges 12 of the cartridge belt 11 from the cartridge belt 11 to the left. It hits the cartridge 12 of the cartridge. In order to convey the cartridge 12 projecting from the lowermost cartridge belt 11 through the curved duct 13 to the firearm 14, another endless conveyor belt 25 is used, which is also referred to as an elevator. It has a number of elevator teeth 26 between which the cartridge 12 is located. The endless conveyor belt of the elevator 25 is guided around three deflection devices 27, 28 and 29.

The lowermost bullet strip 11 has two conveyor screws 3
0 and 31, the tip of the cartridge 12 in the lowermost cartridge belt 11 is on the bullet guide plate 32, and the bottom of the sleeve of the cartridge 12 is engaged with the cartridge belt 11. It is supported not to do so. The downward movement of the bullet guide plate 32 is caused by the movement of another conveying screw 33.
controlled by. According to FIG. 1, the return of the bullet guide plate 32 to its upper position is effected impulsively by the spring 34 as soon as the last cartridge 12 has been ejected from the lowermost cartridge strip 11. A retaining pawl 35 is shown in FIG. 2, which faces the firearm and prevents the cartridge 12 from being accidentally returned to the cartridge belt 11. These holding claws 35 hold the cartridge 12
is automatically returned by being pushed out.
The return of the cartridge from the canister 13 is prevented by a slider 36. This slider 36 is a gear 38
and is raised and lowered by a rack 37 fixed to a slider 36. These movements of the slider 36 must coincide with the downward movement of the cartridge belt 11. The empty cartridge belt 11 is thrown downwards in a manner not shown in detail here.

The magazines of the firearms described up to now belong to the state of the art and will be explained here insofar as is necessary for an understanding of the blocking device according to the invention (FIGS. 3 to 5). As soon as the magazine described is emptied, all cartridge strips 11 are pushed into the magazine 10 from above. This insertion of the magazine into the cartridge should take place before the last empty cartridge strip is ejected, otherwise during the pushing of the first filled cartridge strip 11 both cartridges 12 This is because the endless conveying chains 19 and 20 could impinge on one or the other of the two carriers 23 or 24, whereby parts of the magazine could be damaged or the orderly functioning of the magazine could no longer be guaranteed. . In order to avoid this, a blocking lever 39 is arranged in the magazine 10 described.
The blocking lever should prevent the insertion of a filled cartridge 11 if the last empty cartridge 11 has already been ejected.

According to FIGS. 3 to 5, these blocking levers 3
9 is supported around an axis 40, and when the magazine 10 is empty (FIGS. 1 and 2),
It is pivoted by the spring 41 into the position according to FIG. However, if the cartridge belt 11 (empty or full) is
0, then the blocking lever 39 remains in the position according to FIG. As long as the blocking lever 39 is in the position according to FIG. 3, the stop 42 prevents the insertion of the filled cartridge strip 11. However, bullet belt 1
1. As soon as a particularly empty cartridge 11 is pushed into the magazine 10, this cartridge 11 pushes the blocking lever 39 into the position according to FIG. By means of this blocking lever 39, when inserting a cartridge into the empty magazine 10 of a firearm, first an empty cartridge belt 11 is inserted and only then the required number of filled cartridge belts is inserted. inserted. This first empty cartridge strip 11 prevents the cartridge 12 from striking the driver 23 or 24 of the endless conveyor chains 19 and 20. The operator must push the filled cartridge belt 11 into the magazine 10 with both hands due to the weight of the cartridge 12 and is therefore not in a position to pivot the blocking lever 39 with one hand. On the other hand, the empty cartridge belt 11 can be inserted into the magazine 1 with one hand.
0 and the blocking lever 39 can be pivoted away with the other hand. When inserting the cartridge belt 11 into the empty magazine 10, the empty cartridge belt 1 is first inserted into the empty magazine 10.
1 is inserted, then the cartridge strip is supported on both conveying screws 30 and 31, and the second cartridge strip 11 filled with a cartridge 12 is inserted so that the cartridge 12 abuts against the driver 23 or 24. Magazine up to 10
pushed inside. This means, for example, that the entrainer 24
may also be performed in a position slightly to the left of FIG. 2, rather than in the position shown in FIG. According to FIG. 5, the blocking lever 39 is tilted as soon as the left clip 11 is pushed downwards.
