Abstract

The housing (1) is of a shape corresponding to that of the hand guard of the rifle (2) and is exchangeable for this. The barrel (4) of the accessory firearm is consequently closely adjacent to the barrel of the rifle (2). The trigger (21) and safety device (22) are arranged in the housing (1) at the support point of the firearm combination and both are designed for both left-handed and right-handed actuation. For firing grenades, therefore, the attitude of the rifle (2) does not have to be changed in relation to normal handling. <IMAGE>

Description

The invention relates to a grenade launcher additional weapon for attachment to rapid-fire rifles with a housing designed as a holder which carries at its rear end a breech box in which a firing pin which can be tensioned by hand and a trigger device for the blow Bolt and a locking device is arranged for a tube movably mounted relative to the housing, which tube in its rest position with its rear end adjoins a locking plate forming the front end face of the locking box and is locked with the locking box and the rear end thereof for the insertion of garnet ammunition in the Closure plate is removable.

Such a grenade launcher additional weapon is known from DE-PSs 1 944 625 and 1 944 650. In the known grenade launcher auxiliary weapon, the barrel is slidably mounted in the housing in its longitudinal direction and has a pistol grip with trigger near its rear end on its underside, which engages with the trigger device arranged in the breech box via a rod. when the tube is in its rear position, in which it is adjacent to the lock box and locked with the lock box. After releasing the lock, the tube can be moved from its rear rest position into a front position, so that a space is created between the lock box and the rear tube end, which allows the insertion of ammunition.

Another grenade launcher additional weapon is known in the form of the Grenade Launcher M 203 for the American rapid-fire rifle M 16 A1. To operate this additional grenade launcher, the shooter must hold the rapid-fire rifle with his front hand on the Schnell magazine Detect fire rifle so that he can pull a trigger in close proximity, which is located on the underside of this additional weapon. Here, too, the tube can be displaced in its longitudinal direction in order to release its rear end for the insertion of garnet ammunition.

The known grenade launcher additional weapons have the disadvantage that the rifle cannot be held in their usual manner when shooting, but that the front hand instead of the forearm either grips the pistol grip attached to the auxiliary weapon or even the magazine of the rifle got to. As a result, the two hands holding the rifle are closer together than is favorable for targeted shooting. If the rifle and grenade launcher are to be operated alternately, the shooter must at least grasp the Grenade Launcher M 203.

Accordingly, the invention has for its object to develop a grenade launcher additional weapon of the type mentioned so that its operation does not require changing the hand position compared to normal shooting. This object is achieved according to the invention in that the actuating means for triggering and securing in the housing of the grenade launcher additional weapon are arranged in the support point of the weapon combination above the tube and are accessible on both sides of the housing for both left-handed and right-handed actuation.

Since in the grenade launcher auxiliary weapon according to the invention the triggering and securing means are arranged in the housing in the support point of the weapon combination, the shooter can leave his hands in the usual place on the rifle if he wants to fire the auxiliary weapon instead of the rifle. Since the trigger members for the rifle and the additional weapon are completely different from one another and can be operated with different hands, there can be no confusion. On the other hand, the shooter can concentrate fully on the shot in this case because he is not disturbed by an unusual posture.

In a further embodiment of the invention, the actuation means for the device for tube locking and firing pin tensioning arranged in the lock box are arranged one behind the other in the actuation direction. The arrangement of two separate actuating means for releasing the tube lock and for tensioning the shutter bolt allows the tube to be opened for loading, in particular pivoting out, and thus reloading the weapon without the firing pin having to be tensioned at the same time. The additional weapon according to the invention can therefore be carried in a loaded and at the same time relaxed state, which is optimal both for rapid fire readiness and for high security. On the other hand, the arrangement of the two actuating means one behind the other allows the tube to be swung out for loading with only one hand movement sliding over from the locking lever to the tensioning lever and, at the same time, the firing pin can be cocked when it comes to a very high rate of fire.

In a preferred embodiment of the invention, a locking mechanism controlled by the tube lock releases the trigger device only when the tube is completely locked to the lock box. This ensures the greatest possible security against incorrect handling of the weapon and ensures that a grenade can only be fired when the barrel is properly locked to the housing.

In a preferred embodiment of the invention, the housing is designed in accordance with the handguard of the rifle and can be exchanged for it. In this way, it is possible to integrate the grenade launcher auxiliary weapon into the rifle in such a way that it does not interfere with the underside of the rifle. In particular, the barrel of the additional weapon can be arranged particularly well in this way in the extension of the shoulder system of the rifle, so that no turning torque can occur as a departure error when firing from the shoulder. This design of the grenade launcher additional weapon according to the invention is also of particular advantage for supporting the rifle with the front hand.

The grenade launcher additional weapon shown in the drawing has a housing 1 designed as a holder, which is designed in the same way as the handguard of a rifle and, as illustrated in FIG. 1, can be attached to the rifle 2 instead of the handguard. The housing 1 is provided at its rear end with a lock box 3, to which the tube 4 connects to the front, which in its rest position extends parallel to the housing 1 up to its front end. The tube 4 is connected near its front end to the housing 1 by a hinge consisting of a bearing eye 6 attached to the top of the tube 4, a hinge bearing 7 attached to the front end of the housing 1 and a hinge pin 8 passing through the eye and the bearing consists. On the hinge pin 8 is a biased torsion spring 9 is arranged, which is supported on the one hand on the housing 1 and on the other hand on the tube 4 and strives to bring the tube 4 into the open position shown in dash-dotted lines in Fig. 1, in which the tube is pivoted away from the housing 1 and its rear end is free to insert garnet ammunition. The swivel angle of the pipe is limited by a pipe stop 10 attached to the top of the pipe. This limitation is selected so that the extension of the tube 4 pivoted away from the housing passes the magazine 11 of the rifle 2 and therefore there are no obstacles to inserting garnet ammunition of any length into the tube 4.

In its rest position, the tube is held by locking arms 12 of a bolt arranged in the lock box, which engage in grooves 13 serving as a detent lock, which are mounted in a flange 14 arranged at the rear end of the tube. This flange 14 has wedge-shaped projections 15 serving as a locking slide and hooks 16 which support the locking. A semicircular recess 17 in the flange 14 shows in the rest position of the tube whether the tube contains a grenade.

In the exemplary embodiment shown, the tube 4 has at its rear end a grooved surface 18 that supports the grip. The attachment of the housing 1, breech box 3 and tube 4 to the rifle 2 is carried out at the front end of the housing 1 by a cylindrical pin 19 and in the loading range of the breech box 3 through two cylinder pins 20, the corresponding holes in the grenade launcher and in the rifle 2 penetrate.

As can be seen from FIG. 1, the additional grenade launcher shown is provided with a trigger 21 and a safety slide 22, both of which are arranged above the tube 4 in the housing 1 at a point where the shooter's support hand is located. 3 and 4, the trigger 21 is formed by an angle lever, which engages with an arm 23 in a form-fitting manner in a trigger rod 24, which is arranged on it by a compression spring 25 in FIGS. 3 and 4 Starting position is held. A trigger force F1 acting on the trigger 21 in the direction of the arrow causes a longitudinal movement of the trigger rod 24, so that its rear end deflects the long arm of a trigger pawl 28 pivotably mounted about an axis 27 and thereby pivots the trigger pawl. A nose 29 on the other arm of the release pawl 28 is thereby pulled off a pressure point catch 30 of the firing pin 31, so that the firing pin 31 is released to trigger the shot. The firing pin 31 is then driven by the tensioned firing pin spring 32 to trigger the shot.

The firing pin 31 is guided in a bearing body 33 inserted into the locking box 3, in which a pin 34 is also displaceably mounted in its longitudinal direction and forms a fall protection for the firing pin 31. This bolt 34 has a recess 35, which is in the rest position of the bolt under the release pawl 28. The bolt 34 is held in this rest position by a spring 36. For example, mass accelerations caused by falling or impact, which are suitable for pulling the release pawl 28 from the pressure point latch 30, also cause the bolt 34 to be displaced counter to the force of the spring 36, as a result of which an extension 37 assumes the release pawl 28 and thereby prevents the release pawl from rotating .

3, 5 and 6, the bearing body 33, which is fixedly connected to the housing 1, receives the aforementioned locking bolt 38, which is displaceable in the longitudinal direction of the weapon and by the force of two locking springs 39 arranged on both sides thereof its operative position is pressed, in which its locking arms 12 pass through recesses in the closure plate 41, so that they engage in the grooves 13 on the tube flange 14 when the tube is pressed (FIG. 1). A locking lever 46, which can be actuated in the direction of arrow F2, serves to pull the locking bolt 38 out of its operative position. The locking lever 46 rotatably mounted about the axis 47 engages with two arms 48 in a form-fitting manner in the locking bolt 38 and moves it back against the force of the locking springs 39. A nose 49 on the locking bar 38 engages with a shoulder 50 on the firing pin 31 and takes the firing pin a short distance. As a result, the firing pin tip is retracted behind the front of the closure plate 41 so that it pivots of the pipe is not in the way. Even before the locking arms 12 release the tube, the nose 29 of the release pawl 28 falls into a catch 51 attached to the firing pin 31. If the locking lever 46 is released after opening the lock, the locking lever 46 and the locking bolt 38 are released from the locking springs 39 into the starting position brought back. The simultaneously released firing pin 31 wedges under the force of the firing pin spring 32 with its catch 51 on the nose 29 of the release pawl 28 such that a force exerted on the release pawl 28 is supported by the self-locking catch 51.

An arm 42 arranged in the middle of the locking bolt 38 interacts with a locking mechanism 43 arranged in the locking plate 41, which prevents the firing of a shot if the tube is not properly locked to the locking box. Only when the locking bar 38 assumes its operative position, i.e. the locking arms 12 are advanced as far as the arm 42 stops on the locking plate 41, the middle arm 42 of the locking bolt 38 holds down the spring-loaded bolt 44 of the locking mechanism 43 via inclined surfaces formed on the arm 42 and the bolt 44 and thus holds it in one position, in which the upper end of the bolt 44 is located outside the recess 45 in the trigger rod 24. On the other hand, if the lock is not complete, the Rierel 44 engages in the recesses 45 of the trigger rod 24 and thereby prevents a shot from being fired.

In the bearing body 33, a rocker 54 is also pivotally mounted about an axis 53, which engages around a tongue 52 attached to the rear of the locking bolt 38 and is supported on the bearing body 33 under the load of a spring 55. In the case of a mass acceleration caused, for example, by falling or impact, which is suitable for moving the locking bolt 38 out of its operative position against the force of the locking springs 39, the rocker 54 performs a tilting movement against the force of the spring 55 and thereby engages with an edge 56 in an am Locking bar 38 provided recess 57 a. This reliably prevents the barrel from being accidentally unlocked due to the weapon falling or thrusting.

The guided in the bearing body 33 and movable in its longitudinal direction firing pin 31 is in a manner not shown in positive engagement with a pivotally mounted about an axis 66 tension lever 58 in a positive connection, such that by pivoting the tension lever 58 by a force acting in the direction of arrow F3 a Longitudinal movement of the firing pin 31 with simultaneous tensioning of the firing pin spring 32 results. The firing pin 31 can be moved in this way until the nose 29 of the release pawl 28, which is loaded on its long arm by two springs 26, engages in the pressure point latch 30 on the firing pin and thereby fixes the firing pin in its tensioned position. After release, the tensioning lever 58 is returned to its starting position by a spring 60. During the cocking movement of the firing pin 31, a signal pin 59 formed on the firing pin emerges from the rear wall of the breech box and thereby indicates the cocked state of the weapon.

3 and 4, the above-mentioned fuse 22 is formed by a slide mounted in the housing 1 and movable transversely to the housing, which engages with a shoulder 62 in a corresponding transverse groove 63 of the trigger rod 24. In this position, the trigger rod 24 is accordingly secured against displacement in its longitudinal direction. By moving the safety slide 22, its shoulder 62 can be disengaged from the recess 63 of the trigger rod 24, so that the trigger rod is then released to trigger a shot. In order to prevent unintentional unlocking of the weapon or even an unintentional firing of a shot by lateral forces exerted on the safety slide 22 or the trigger 21, protective webs 64 and 65 protruding laterally on the weapon housing 1 are formed above the trigger 21 and the safety slide 22, which largely prevent unwanted touching of the trigger and safety slide by hitting or passing objects.
