Definitions

• the invention relates to a fully automatic self-loading weapon with a functional part which is movable by the firing of a shot, and with an individual firing device which can be switched on and off and which permits the firing of individual fires (preamble of claim 1).
• “Functional part” here means a component that is moved by the energy released when a shot is fired, such as the barrel, a gas cylinder, the breech, other parts forced by these elements, such as a cock, etc.
• a movable mass body that is mechanically completely independent of the barrel and breech can also form such a functional part if it acts during the backward movement of the weapon ceases to fire as a result of firing a shot, seeks to maintain its position and consequently shifts relative to the weapon.
• a switchable individual firing device is often provided, which is set up to enable a single shot to be fired after being switched on.
• a fire selection device is provided which enables the shooter to operate the weapon either in single or continuous fire mode.
• the individual fire mechanism is generally controlled by a functional part of the type mentioned above, but can in principle also have an independent mechanism, for example a delay mechanism.
• Such a delay mechanism causes the connection between the trigger, which is then still being pulled, and a latching arrangement to be interrupted shortly after its release after the firing of a shot, so that the cock or the hammer (in the case of a shooting weapon) or can hold the breech (in the case of a firing weapon) to prevent the firing of a second shot.
• the invention has for its object to develop a weapon of the type mentioned in such a way that the delivery of a reliably short burst of fire is made possible with simple means.
• This object is achieved according to the invention in that after the firing of a shot with the individual firing device switched off, it can be actuated by the movement of the functional part in such a way that only a single, further shot is fired.
• the invention now not only reduces the known three-shot burst to two shots, but in particular does not require any further mechanism in that, controlled by the movement of the functional part, after the first shot has been fired in the continuous fire mode, the latter automatically fires into it changes the single-fire mode so that the second shot is fired with the gun set to single fire, which thus interrupts the fire after this second shot.
• the functional part can be diverse.
• the closure is the most functional part.
• the breech could also be used with a weapon that has a cock.
• a weapon that has a cock.
• the switching process according to the invention for individual fires does not take place so early that there is a risk that the individual firing device will interrupt the sequence of movements required to fire a shot as soon as the first shot is fired.
• the gunner could not rely on a "two shot” weapon to really fire two shots.
• the tap itself is used as a functional part, then the point in time when the individual firing device is switched on can be determined structurally without adding up tolerances, as would be possible in the transmission from a further functional part.
• the applicant has developed a trigger device which has already been referred to above and which, like the trigger device of the rifle G3, has a longitudinally displaceable and pivotable trigger lever on the top of the trigger, which causes the interruption process in the single fire.
• the cock presses the trigger lever backwards so that its rear end is located over a projection of the trigger.
• the projection is in turn behind the pivot point of the trigger.
• the projection moves upwards, which in turn engages under the rear end of the trigger lever and thus pivots it with its front end downwards and out of engagement with the latching recess.
• the tap knocks off, and at the same time the trigger is pushed forward so that its rear end slips forward from the projection and assumes its original swivel position, in which it can again engage in the stop of the tap.
• the projection dips down under the trigger, which is released and is pushed back. The starting position before the shot is fired is restored.
• This holding claw could be mounted so loosely that it is able to avoid the cock when it moves backwards (clamping movement). It is particularly advantageous, however, that the holding claw has a pawl which is designed so that it dodges the cock during its tensioning movement, but is grasped by the cock during its downward movement and is carried along until the cock as a result of the circular path it travels , disengages from the latch (claim 5).
• the holding claw After the holding claw has been pivoted by the pawl that has been carried along and has thereby released the slide, it is moved back to its starting position by a spring in order to be able to reach behind the slide again when the trigger lever holds the cock cocked after the second shot. If the trigger is now released and pulled again, the process described for firing two shots is repeated. In order to enable continuous fire, the holding claw must therefore be pivoted out of engagement with the slide and held in this pivoted-out position.
• a fire selection shaft known per se, which carries an actuating lever on one or both ends and which can push through the slide so that it can move the slide for by protrusions on its outside depending on its rotational position allow the single fire, and can prevent the continuous fire.
• either the retaining claw has a projection and the fire selection shaft has a recess or the retaining claw has a recess and the fire selection shaft has a projection, which are arranged such that the respective projection falls into the associated recess when the fire selection shaft is still in one position located in the single fire area (claim 6).
• the holding claw is permitted to intervene in an inhibiting manner in the slide.
• a locking position for the actuating lever is created.
• the fire selection shaft rotates and the projection of the holding claw runs onto the outer circumference of the shaft or the projection of the shaft onto the outer edge of the holding claw, so that it swings away from the fire selection shaft and thus from engagement with the slide and is therefore ineffective .
• Fig. 1 shows a longitudinal section through a handle with trigger device equipped with the two-shot device according to the invention
• FIG. 2 is a partial external view of the handle piece of FIG. 1.
• a cock 1 is in Fig. 1 in a cocked position, in which the front tip of a trigger lever 2 engages in the rear of the two locking recesses of the valve 1 and the valve 1 presses the trigger lever 2 against the action of a trigger spring 7 to the rear.
• the trigger lever 2 has an elongated hole, with which it is pivotally mounted about the pivot pin of a trigger 3 and movable longitudinally.
• the trigger 3 is in its rest position, in which it is prevented from pivoting further about the pivot pin to the front, and has at its upper, rear end a projection on which the rear end of the trigger lever 2 is seated. Therefore, this can not give in to the torque that is applied by the cock 1 loading him at the front end.
• the trigger 3 If the trigger 3 is moved backwards, i.e. pulled off, then the projection of the trigger 3 presses against the rear end of the trigger lever 2 and swivels it with its front end downward, so that the trigger lever 2 with its front end comes out of the locking recess of the tap 1 exits and has this knocked off.
• the tap 1 now strikes the shutter bolt (not shown), the cartridge is ignited and the shutter moves backwards, causing the tap 1 to be tightened again (moving clockwise when looking at the drawing).
• the valve 1 runs through with its rear locking recess under the front end of the trigger 2, reaches its dead center and reverses its direction of movement, since meanwhile the closure also moves forward again.
• the rear locking recess runs onto the front end of the trigger 2 and pushes it backwards.
• the trigger lever 2 can not give in, however, because it strikes with its rear end against the projection of the trigger 3, which is still pulled.
• the trigger 3 If the trigger 3 is now released, then it returns to the position shown in FIG. 1. His protrusion dips back under the rear end of the trigger 2 and the trigger 2 is moved so far back by the tap 1 that it sits with this rear end again over the projection and assumes the position shown in FIG. 1.
• the weapon can only be fired in single fire.
• the tap 1 also has a front latching recess, into which a latching formation can engage, which is designed as part of a trigger 5, which is mounted on the front part of the handle on the upper side and projects upwards into the movement path of the closure (not shown).
• the tap 1 only moves a short distance until the front end of the trigger 2 engages in the rear catch recess.
• a slide 4 is slidably mounted, which is perforated and penetrated by a fire selection shaft 12 which has cams on its outer surface which can be brought into engagement with the walls of the opening.
• a first angular position of the fire selection wave 12 continuous fire position
• the slide 4 is in a rear position and is held there.
• a second angular position single fire position
• the slide 4 can move in the longitudinal direction over a certain distance.
• the slide 4 has at the front on its underside a downwardly extending slide finger 4b which engages in a recess in the trigger lever 2 from above.
• the trigger 2 can move freely in its longitudinal direction and thereby trigger the interruption process.
• a leg spring 11 counteracts this movement with its upper leg, but is overcome by the stronger trigger spring 7.
• the slide finger 4a holds the trigger 2 in its position shown in FIG. 1, so that it only swings, but not in its position Can move longitudinally. If the trigger 3 is now pulled and the trigger lever 2 is pivoted so that it must release the engagement with the tap 1, then the trigger lever 2 can no longer pivot back, but must release the tap 1 as long as the trigger 3 remains pulled. The trigger 5 then takes over the control of the tee-off process.
• the cock 1 has a cock hump la, the radius of the movement path of which is greater than that of the rest of the cock 1. Furthermore, a holding claw 10 is pivotally mounted at its rear end on a bearing pin 13 and pivoted downward by the second, lower leg of the leg spring 11 .
• a pawl 8 is pivotally mounted, which is pivoted forward by a pawl spring 9 relative to the holding claw 10. In the position of Fig. 1, the pawl 8 projects into the movement path of the tap hump la.
• the holding claw 10 has at the front on its underside a downwardly extending holding claw hook 10a, which in the position of FIG. 1 engages behind a slide lug 4a of the slide 4 from the front and thus holds the slide 4 in its rear position, even though it is in the shown position of the fire selection shaft 12 should move forward.
• the tap 1 knocks off (moves counterclockwise) and is cocked again after the triggering of a shot (moves clockwise).
• the Hahnhöcker la passes the upward slope of the pawl 8 and presses it temporarily against the action of the pawl spring 9 into the holding claw 10.
• the tap 1 since it has been released by the latching formation, again passes the trigger lever 2 and practically takes the pawl 8 with the tap hump la at the same time.
• the pawl 8, together with the holding claw 10 on which it is mounted, is pivoted upward out of the movement path of the tap hump la, as a result of which the holding claw hook 10a is lifted upward above the slide block 4a.
• the slide 4 is pressed forward by the compression spring 7 via the trigger lever 2, and the trigger lever 2 can assume its front position and hold the rear catch of the valve 1 when it starts up against it again in the manner described above.
• a new two-shot burst can now be fired when trigger 3 is pulled again.
• the top of the fire selection shaft 12 has a depression into which a projection (in the position shown in FIG. 1) falls on the underside of the holding claw 10. If the fire selection shaft 12 is rotated, then this projection and thus the holding claw 10 are pushed up into a position in which the pawl 8 is out of engagement with the movement path of the tap hump 1 a.
• the slide 4 can by the respective angular position of the fire selection shaft 12 in the rear continuous fire position fixed or released for single fire for longitudinal movement.
• the fire selection shaft 12 also has a recess on its underside, into which an extension (not shown) at the rear, upper end of the trigger 3 can be inserted. If the fire selection shaft 12 is rotated so far that this immersion is no longer possible, the trigger 3 is blocked and the weapon is thus secured.
• a fire selector lever 14 is shown, which sits firmly on the end of the fire selector shaft 12 and this optionally in the position "S" (safe), “E” (single fire), “2" (two-shot) and “F” ( Continuous fire) can move.
• a bearing pin for the holding claw 10 is designated.
