Abstract

The invention relates to a shooting system comprising a housing (1) and parts that can be moved relative thereto, i.e. a tube (2), a tube closure (3), and a silencer (5), as well as a non-self-locking threaded spindle which has a left-handed threaded section (4a) in one of the halves thereof while having a right-handed threaded section (4b) in the other half. The silencer and the tube closure are mechanically coupled to one respective threaded spindle section by means of one respective nut (N, N1) such that a translational movement of the silencer (5) is converted into a rotational movement of the spindle and the movement of the spindle is converted into a translational movement of the tube closure (3), in such a way that both parts perform translational movements in opposite directions because of the right-handedness and left-handedness of the spindle. The tube (2) is disposed to also be movable relative to the housing (1) and can be coupled to the tube closure (3) in such a way that the tube is entrained by the tube closure at least during a translational movement of the tube closure, during which the tube closure moves away from the silencer from a shot-triggering position.

Description

Shooting system and method of operating the shooting system

The invention relates to a shooting system for shooting large-caliber projectiles and shells and a method for operating the shooting system.

There are known large-caliber firearms, which are operated manually in terms of target setting and operation and are transported by a person. In order to ensure the target setting, the manual operation and the transportability, such a shooting device must be easy and simple to use and have a high accuracy of aiming. In order to achieve high efficiency, the shooting system should be able to fire several shots in rapid succession, ie at a high frequency. For use in the field is also required that the shooting system has a simple and robust design, so that their function is not impaired if soiled or shock. The shooting system should work as quietly as possible in order to make it difficult to locate them. For reasons of security of the shooting and increasing the effectiveness of the shooting system, it is also necessary that the shooting system in a short time in shooting readiness can be brought. To avoid high costs in the operation of the shooting system, it is advantageous if the shooting system allows the use of low-cost ammunition.

However, it is also known that in large-caliber shooting facilities due to the high mass of the projectiles to be accelerated large recoil forces occur and that heavy caliber ammunition is difficult to reload manually. That is, due to the large recoil forces, regardless of the aiming ability of the shooter at relatively fast successive shots the required accuracy is not guaranteed. Furthermore, the high weight of the ammunition makes it difficult for the shooter to reload quickly. It is known from DE 692 11 563 T2 a weapon system with a damping device, in which a fired when firing a projectile recoil is directed to a launching tube and this launching tube shifts due to the recoil force in the opposite direction to the firing direction of the projectile, wherein it Displacement process is slowed down and continues to shift after the deceleration. This means that in the weapon system shown in DE 692 11 563 T2 the recoil takes place in two stages, so that the full recoil pulse does not act on a shooter when firing.

US 2003/0056639 A1 discloses a recoil control mechanism in which the expansion of explosive gases and the pressure applied by the gases to adjacent components serve to temporarily displace the launching tube during firing in the same direction as the projectile emotional. This largely minimizes recoil on the entire system.

Some of the above drawbacks have already been overcome by a firing system disclosed in the Georgian patent specification GE P 2006-3883. This document discloses a shooting system in which a muffler and a tube closing a tube closure are each coupled via a nut to a spindle, wherein the muffler is coupled to a threaded portion of the spindle with right-handed thread and the tube closure to a left-hand threaded portion of the spindle. The respective spindle threads have such a pitch that the spindle or its threaded portions do not act self-locking, ie the spindle is fixed in the middle by two thrust bearings and is in the rotatable state. The central spindle bearing takes place in the housing of the shooting system. The tube or the barrel of the shooting device is also firmly connected to the spindle bearing or the housing. In case of explosion of a charge of a projectile in the pipe of the shooting system Exploded gases expand in the shooting system in such a way that they act laterally on the muffler. Due to the pressurization, the muffler performs a translational movement in such a way that it moves away from the pipe support in the housing. By coupling the muffler via a nut to a spindle portion and by the non-self-locking action of the spindle, the spindle begins to rotate, resulting in entrainment of the nut for coupling the tube closure to the spindle, resulting in an opposing pitch of the spindle portion on which the nut of the tube closure is arranged, the tube closure moves with the tube in the locked state in the opposite direction to the muffler relative to the housing. That is, as the spindle rotates, the muffler and the tube shutter synchronously move away from each other in opposite directions. The recoil pulse of the movement of the tube closure is thus directed counter to the recoil impulse of the projectile and the silencer. This results in a minimization to the cancellation of the bullet recoil impulse, since the silencer and the pipe closure are connected by nuts to the spindle and the weight of the pipe closure corresponds to the weight of the silencer and the explosion gas pressure surface of the silencer corresponds to the explosion gas pressure surface of the pipe closure.

A drawback in this embodiment is that in order to compensate for the recoil pulse from the projectile in the muffler, the tube closure must be correspondingly heavy in order to generate an approximately equal recoil pulse as the recoil pulse is generated by the movement of the projectile and muffler as the tube closure moves , However, the relatively high weight of the tube closure thus causes an increase in weight of the entire shooting device, whereby the handling and transportability of the shooting device difficult. The present invention is therefore an object of the invention to provide a shooting system with zero recoil and method for operating a shooting system available, which allows a low-precision and easy handling accurate shooting of large-caliber cost-effective projectiles in high frequency.

This object is achieved by the features mentioned in claims 1 and 40. Advantageous embodiments are specified in the respective subclaims.

It is a shooting system with housing and relatively movable parts pipe, pipe closure and muffler and a non-self-locking threaded spindle (ie, a freely rotatable spindle) provided in which the threaded spindle in one of its halves a left-hand threaded portion and in the other half having right-handed threaded portion, wherein the muffler and the pipe closure are mechanically coupled via a respective nut to a spindle threaded portion, so that in a translational displacement of the muffler whose movement is converted into a rotational movement of the spindle and their movement in turn into a translational movement of the pipe closure is converted so that due to the right and left handedness of the spindle or its sections, the two components silencer and pipe closure perform translational movements in opposite directions. The tube of the shooting system is also arranged to be movable relative to the housing and can be coupled to the tube closure such that it is taken away from the tube closure at least in a translational movement of the tube closure, in which the tube closure from the muffler from its firing position. By the system according to the invention takes place while shooting a movement of the mass of the tube and the tube closure in the opposite direction to the movement of the projectile and the muffler, whereby a recoil is generated by the movement of the tube and the tube closure, which is directed opposite to the recoil of the projectile and the silencer.

The threaded spindle is advantageously a ball screw, which has at its two halves each having a thread with different orientation of the edge pitch, that is, that the threaded portion is left-handed at one end of the spindle and the threaded portion at the other end is right-handed. The pitch itself can be the same or different in amount for both threaded sections. The greater the pitch in the threaded portion coupled to the tube closure, the more effectively the recoil of the bullet is reduced. With the same pitch value in the two threaded sections of the spindle, the translatory movements of the pipe closure and silencer are synchronized in opposite directions.

In a preferred embodiment, the shooting system further comprises an automatic triggering mechanism which, upon reaching a path end position of the pipe closure and the pipe at a maximum distance from the muffler, effects a solution of the pipe from the pipe closure. With the design of the shooting system with the automatic release mechanism is achieved that in the movement in which removes the tube closure of the muffler and thus the storage of the spindle in the housing, the tube is taken from the tube closure, so that the weight of the tube and tube closure or whose total inertial force is used to minimize the recoil of the projectile, wherein upon reaching a path end position, this connection between the pipe and pipe closure is released.

Furthermore, it is envisaged that the shooting system comprises a first force-applying device which, at least in its path end position at a maximum distance from the tube Silencer exerts a force in the direction of the silencer. This force-applying device is advantageously a spring which acts on the pipe so that after the solution of the coupling of the pipe from the pipe closure at the maximum distance from the muffler that this moves back without the pipe closure in the direction of muffler or shot firing position. An ammunition chamber formed by tube closure and tube is thus opened and a sleeve still in the ammunition chamber after the shot can be removed through the opening of the ammunition chamber.

Furthermore, it is provided that the shooting device has a fixing element, which causes in the position of the pipe closure in the maximum distance from the muffler a latching and thus fixing the pipe closure in the housing. By means of this fixing element ensures that the pipe closure is held at this maximum distance from the muffler in the housing. As a result, as already described, the ammunition chamber formed by the pipe and the pipe closure can open when the pipe is loosened from the pipe closure and the pipe is returned to the firing position.

In an advantageous embodiment of the shooting system is further provided that a second force-exerting device is provided between the spindle and at least one of the two components silencer and pipe closure, which upon removal of the respective component from the center of the spindle, a force on the component towards the center the spindle exercises. As the center of the spindle is understood in this case the anchoring or storage of the spindle in the housing. In this case, the second force-exerting device acts on the muffler or on the tube closure such that they are pressed in the direction of the bearing of the spindle in the housing or in the direction of transition between the two differently aligned spindle thread sections. Furthermore, it is provided that the tube has a driver which comes into contact with a stop of a traction mechanism when the tube moves from the coupled position at maximum distance from the silencer back into the firing position, thereby actuating the traction mechanism in that the fixing element coupled to the pulling mechanism releases the latching with the tube closure, so that the tube closure returns to its firing position under the action of the second force-applying device. This means that shortly before reaching its firing position (position of the shooting readiness), the pipe actuates a further mechanism via a driving lug, which causes a movement of the fixing element, which thereby also releases the pipe closure, under the force of the second power device towards the silencer and thus moves towards firing position and thus closes the ammunition chamber again. Prior to this closure of the ammunition chamber has added this new ammunition. The delivery of a new shot can thus be initiated.

Advantageously, the second force applying device consists of two spring trains, each spring pull comprises at least one pull rod and both spring sets and tie rods are in the hollow core of the spindle and one of the tie rods at one end by means of a nut in the muffler and the second pull rod by means of a nut in Pipe closure is attached.

The second ends of the tie rods of the second force-applying device are in the starting position freely on the inner flange of the spindle and have at their ends flanges for limiting the displacement of the spring trains or for their investment.

In an advantageous embodiment it is provided that the spindle at their outer end regions in each case a flange has, on which a second coil spring is supported to cushion a pulse generated by a nut in the translational movement of the muffler and the tube closure. At the same time causes this second coil spring in the depressed state also a force on the sound and the tube closure in the direction of the respective opposite component, ie in the direction of transition between the two differently oriented threaded portions of the spindle.

In a further advantageous embodiment of the shooting system is provided that on the housing two handles are arranged displaceable relative to each other, wherein the second handle has a second driver which cooperates with a third driver on the muffler such that at a distance-increasing displacement of the two handles the muffler is entrained by the second handle and is also removable from the first handle. That is, the two handles are displaceable relative to each other and relative to the housing, and that displacement of the muffler (and the tube with tube closure in opposite directions to the stop) relative to each other causes displacement of the muffler and thus rotation of the spindle without there being any detonation of ammunition in the ammunition chamber formed by the pipe and pipe closure. Thus, the first time loading a cartridge into the tube and the production of the shot readiness is possible when under the force of the first and the second force applying devices, the tube and the tube closure have returned to their original positions or shot firing positions. In the relative movement of the two handles to each other so that they are pulled apart, a trigger mechanism is tensioned, so that the shooting device is now ready to fire. When a trigger mechanism is triggered, a new shot can be fired. To actuate the automatic release mechanism on the housing a paragraph is provided, which realizes the solution of the pipe from the pipe closure in the movement in which the pipe plug from the silencer.

It is envisaged that the automatic release mechanism is arranged in the pipe closure and having a separator which comes with maximum removal of the pipe closure from the muffler at the shoulder to the plant, being due to the relative movement of the pipe closure to the housing, the automatic triggering mechanism is actuated in such a way that it causes an unlocking of the coupling between the tube and the tube closure. That is, a disconnector in the automatic release mechanism abuts the heel on the housing, this disconnector being moved, thus actuating the automatic release mechanism such that, under the action of a force on the tube, the tube disengages from the tube closure and retracts towards the muffler , which opens the ammunition chamber.

Advantageously, it is further provided that the release mechanism having the automatic release mechanism further comprises a pivotally mounted in the pipe closure rocker arm, one end of which is pivotally mounted on the separator and the other end in the ready to fire state and during movement of the pipe closure and the pipe in the this is removed from the muffler, is engaged in a recess in the tube and thus couples the tube closure with the tube and blocks a relative movement of the tube to the tube closure. The rocker arm thus forms a lock connecting the pipe with the pipe closure.

When the separator is applied to the heel, the rocker arm is swung out of the recess in the pipe. The coupling of the pipe with the pipe closure in the removal movement from the muffler thus happens by a rocker arm, the one-stop in one of tube and pipe closure co-formed recess engages. When the trigger mechanism or the separator on the shoulder on the housing of the rocker arm is actuated so that it is swung out of the recess in the pipe and thus lifts the coupling between the pipe plug and pipe. The tube can now, as described, move back under the action of a constantly acting force in the direction of the silencer and thus in the firing position.

In a further embodiment of the invention, it is provided that a sleeve is arranged concentrically on the tube relative to this longitudinally displaceable whose longitudinal displaceability on the tube is limited by a first and a second shoulder on the tube. The first paragraph on the tube is located at the mouth end of the tube, from which the bullet escapes after firing.

It is further provided that the first force-applying device is at least one spiral compression spring which is arranged substantially concentrically on the sleeve and in the muffler between these components, wherein the spiral compression spring on the one hand on a mouth-side outer shoulder at the end of the Sleeve, which is opposite to the coupling of the tube on the pipe closure, supported and wherein the other end of the spiral compression spring is supported on an inner shoulder on the muffler. When driving apart of the muffler and pipe and pipe closure in opposite directions, the inner shoulder presses on one side of the silencer against the spiral compression spring and the mouth-side outer shoulder of the sleeve is located on the muzzle-side first paragraph on the pipe, wherein the movement of the pipe itself the sleeve shifts relative to the muffler and thus the spiral compression spring is compressed or clamped. Thus, it turns out that when the separator on the shoulder on the housing of the rocker arm is pivoted out of the recess in the pipe and that the spiral compression spring on the one hand against the inner shoulder of the muffler and on the other hand presses against the mouth-side outer shoulder at the end of the sleeve, which in turn rests against the pipe at the first mouth-side shoulder, so that the pipe is pulled back toward the muffler in this.

The shooting system furthermore has a cartridge chamber or ammunition chamber, the inner wall of which is essentially formed by the pipe and the pipe closure. That is to say, the inner wall is a cartridge chamber designed substantially as a hollow cylinder, for example, which is formed partly through the tube and partly through the tube closure. Upon displacement of the tube due to the spring force in the muffler inside, thus opening the cartridge chamber.

The cartridge case is held in the tube cap with a locking hook until the cartridge chamber is fully opened and ejected by the butt of the reflector attached to the returning tube (moving to the home position).

This structural design has the advantage of venting and cooling of the exposed cartridge chamber interior. The venting of the cartridge chamber after each shot results in a temperature reduction of the cartridge chamber even with a large number of shots fired in a short time, so that ammunition can be used with housing materials having a low melting point. For example, unlike conventional ammunition, this material used to make the ammunition can be a plastic.

In an advantageous embodiment, it is further provided that the shooting system comprises a recharging device which is mechanically coupled to the pipe and / or the pipe closure such that the movement of the pipe and / or the pipe closure recharge a new cartridge from a brought to the shooting device coupled magazine in the cartridge chamber. It can thus be automatically recharged new ammunition, wherein the kinetic energy of the tube and / or the tube closure is used for the reloading of a new cartridge in the cartridge chamber of the shooting system.

To trigger a shot of the shooting system is provided that this has a spring-assisted firing pin, wherein the force acting on the firing pin spring is a compression spring which acts in the compressed state on the firing pin in the direction of the muffler. Taking advantage of the spring force of the firing pin can be pressed in the direction of the muffler and thus in the direction of the cartridge, the firing pin abuts with its tip into the cartridge and thus causes an explosion of the explosive charge of the cartridge.

In a particular embodiment of the shooting system is further provided that the shooting system comprises a trigger mechanism, which combines the functions of the autonomous and automatic trigger and is configured such that the autonomous-automatic trigger mechanism, the firing pin in the approach movement of the pipe closure to the muffler holding in a position in front of the tube closure position of the shot readiness, and the firing pin releases on reaching the position of the shot readiness of the tube closure, so that it also moves under the action of a spring force in the direction of the cartridge chamber and thereby pushes into a cartridge. This ensures that a new shot is triggered by the impact of the firing pin in the cartridge only when the tube closure is back in the position of the shot readiness and a new cartridge was invited. In this embodiment, it is provided that the autonomous automatic trigger mechanism has a stop which is coupled to a tilting element on which the firing pin comes into abutment in its fixed position and thus blocked, wherein the stop, the coupling to the tilting element and the Tilting element itself are designed such that the tilting element then causes the release of the firing pin, when the separator comes to rest in his approaching movement of the muffler at the stop and this moves. The stop and the tilting element can be coupled together by means of a coupling rod. On the firing pin, the spring force of a compression spring, which causes the firing pin is moved abruptly towards the muffler, when the firing pin is released when the disconnector abuts the stop. Thus, the shot firing can be effected autonomously, without manually a process must be initiated.

Preferably, it is provided that a compression spring is arranged in the tilting element, whose spring force presses the tilting element in the blocking position. This means that the compression spring pushes the tilting element into such a position that the tilting element blocks the movement of the firing pin until the disconnector comes into abutment against the abutment and counteracts the compression spring force, lifting the blockage of the firing pin, so that the latter is subjected to spring force in the direction of the muffler moves and thus enters a cartridge.

In order to enable a repetitive shot firing, it is provided that the firing pin and the autonomous-automatic trigger mechanism are designed such that when the removal movement of the pipe closure and the firing pin mounted in it from the muffler passes the firing pin on the tilting element, without this to be blocked. For this purpose, the needle has on the side facing away from the muffler a slope, which causes when the impact of the striker to the tilting element in the Removal movement with respect to the muffler of the firing pin the tilting element simply moves against the spring force and thus can go over the tilting element.

Furthermore, it is provided that the stop, the disconnector and the rocker arm are designed such that upon contact of the disconnector on the stop the disconnector pivots the rocker arm back into such a position that the rocker engages again in the recess in the pipe and thus the pipe locked with the pipe closure. This configuration causes the pipe can not solve the pipe closure due to friction and gas pressure forces in a new shot.

In a further embodiment of the shooting system, this has a hand-operated trigger mechanism, which in turn comprises a coupled to a trigger gear, which acts on a tilting rocker.

To connect the trigger or the gear of the manually operated trigger mechanism with the tilting rocker is provided that the manually operable trigger mechanism comprises at least one tie rod between the trigger and the tilting rocker. By means of this tie rod is ensured that the movement of the trigger cock is converted into a tilting movement of the tilting rocker.

It is advantageously provided that the tilting rocker is rotatably mounted in the housing so that it holds the firing pin in the approach movement of the pipe closure to the muffler in a position in front of the position of the shot readiness. By the detention of the firing pin in the approach movement of the pipe closure, on which the firing pin is arranged, it is ensured that the force acting on the firing pin spring is tensioned. Through the actuation of the trigger cock, the tilting rocker can be tilted over the gear or via the pull rod of the manually operable trigger mechanism such that it releases the firing pin. Under the influence of the tense Spring or its spring force thus shoots the firing pin toward the muffler and strikes a cartridge and triggers the explosion of the explosive charge in the cartridge, whereby a new shot is initiated.

In order to increase the flexibility of the shooting system according to the invention, it is provided that the firing pin is designed such that the tilting rocker of the manually operated trigger mechanism as well as the tilting element of the autonomous automatic trigger mechanism can be applied next to each other on the firing pin for the purpose of their blocking. That is, the shooting system can have both the manual trigger mechanism and the autonomous-automatic trigger mechanism. Both trigger mechanisms are designed in such a way that the actuation of one trigger mechanism does not hinder the actuation of the other trigger mechanism. Both trigger mechanisms partially comprise the same components.

It is further expediently provided that the firing pin and the manually operable trigger mechanism are designed such that during the removal movement of the tubular closure and the firing pin mounted in it the firing bolt passes over the tilting rocker, without being blocked by this. For this purpose, the needle on the side facing away from the muffler has a slope which causes when tilting the firing pin on the tilting rocker in the removal movement of pipe, pipe closure and firing pin away from the muffler away the firing pin, the tilting rocker simply against a force acting on the tilting rocker Spring force shifts and thus can go over the tilting rocker.

In a preferred embodiment of the hand-operated trigger mechanism, this further comprises a two-toothed carriage with a first tooth rotatably supported on the carriage and the second tooth fixedly mounted on the carriage and the first tooth against a spring force from a substantially vertical position is tiltable relative to the carriage exclusively in the direction of trigger. This means that the first tooth can be tilted in the direction of the trigger with a force acting on it in the direction of the trigger, wherein the first tooth is fixed in the opposite direction when force is applied.

For reasons of structural simplification can be provided that the carriage is made in one piece with the pull rod.

Furthermore, it is provided that acts on a rocker beam of the tilting rocker on the housing supporting compression spring which presses the tilting rocker in the compressed state in the direction of the position in which is provided with a provided on the tilting rocker first tooth of the firing pin lockable. This means that blocks the tilting rocker of the firing pin when only the loading rocker with the compression spring force.

In a further embodiment, it is provided that the tilting rocker is articulatedly mounted in the housing and has a second tooth at its end opposite the first tooth, wherein each of the teeth extends from the rocker beam in opposite directions substantially perpendicular to the rocker beam.

Furthermore, it is provided that the second tooth of the tilting rocker is in blocking the firing pin by the tilting rocker in such a position that it can be contacted by the sliding of the carriage in the direction of one of the two teeth on the carriage, so that a shift of the second tooth and thus a rotational movement of the tilting rocker such that it gives up the blocking of the firing pin. This means that when the first tooth rests against the firing pin, it is blocked. However, if the tilting rocker is moved because a tooth of the carriage presses against the second tooth of the tilting rocker, then this turns and releases the blockage of the firing pin. The released firing pin shoots towards the cartridge and penetrates into it, causing a shot is fired. By the rotational mobility of the first tooth on the carriage has the advantage that the trigger can be pulled through quickly first, whereby a first shot is triggered. The tooth on the tilting rocker is then between the two teeth on the slide. The carriage can thus be pulled further in the direction of the trigger, whereby the second tooth on the carriage comes into engagement with the second tooth on the tilting rocker. Upon pressure of the second tooth on the slide on the second tooth on the tilting rocker a sustained fire is thus triggered, since in this situation only the autonomous trigger mechanism is operated, which runs automatically. After releasing the trigger, the carriage moves away from the trigger, the second tooth presses on the tilting rocker against the first tooth on the carriage, which is rotated about its pivot and against a spring force, so that at unchanged angular position of the tilting rocker of the carriage in the Position can be reached, in which single fire is triggered by pressing the trigger. This means that the second tooth on the tilting rocker rotates the first tooth on the carriage, so that the entire removal mechanism can again reach a position corresponding to the resting state of the shooting system.

In a preferred embodiment of the shooting system is further arranged in this a separator which is movable in displacement of the first handle relative to the housing and the subsequent displacement of the fixedly connected to the first handle plunger, whereby the separator a the tube in Schuss- Release position fixing lock of the entire lock opens. This can be done via the relative displacement of the first handle, the unlocking of the pipe to allow it to be taken from the pipe plug and thus can be removed from the muffler in the housing.

It is provided that the disconnector is a rotatably mounted in the housing rocker arm, which performs a rotational movement upon application of force by the plunger, that it presses on a pressure surface of the likewise rotatably arranged in the housing lock and this moves so that a volume element of the lock of the entire lock from a complementary to the volume element configured recess in the tube is moved out. By pulling out the volume element of the lock from the recess in the pipe is thus ensured that the tube can move relative to the housing in this.

It can further be provided that between the housing and the first handle a detection device is arranged, which allows a fixation of the first handle and the plunger in a position in which the plunger via the separator causes an opening of the lock of the entire lock. Thus, a constant release of the tube in the firing position in the direction of movement of the removal of the tube and the tube closure can be ensured by the muffler. This allows the continuous repetition of the shooting process (continuous fire) without having to constantly move the handles relative to the housing.

In a special embodiment of the shooting system it is provided that the pipe forms at least one chamber together with the silencer and the sleeve in the ready-to-fire state, wherein the pipe forms at least one wall of the chamber and the pipe connects at least one pipe connecting the interior of the pipe with the interior of the chamber Having discharge opening, so that in detonation of the explosive charge of the cartridge resulting explosive gases flow from the interior of the tube into the chamber. The explosion of the explosive device of the cartridge, which is triggered by the impact of the firing pin in the cartridge, produces explosive gases that expand within a very short time while the bullet is still in the barrel. The explosive gases are under a very high pressure in the pipe so that they flow through the gas discharge opening into the chamber between the pipe and the muffler. Due to the all-round pressurization, the flowing explosion gases press through gas-discharging openings on the one hand on the muffler and on the other hand on the sleeve. Since the sleeve, muffler, tube and tube closure are in the locked state, the explosion gases act on the sprung sleeve, which presses on the separator and opens the shooting system. By the movement of the muffler relative to the housing, the nut is moved on the muffler on the spindle so that it rotates and thus the nut on the tube closure in translation, so that the tube closure together with the tube on the one hand and the muffler on the other in opposite directions remove each other. This described procedure, however, only starts when the lock, which locks the position of the pipe in the housing, has been opened prior to the firing of the shot via a relative displacement of the first handle and the plunger. In the above-mentioned fixation of the first handle and the plunger in a position in which the plunger causes an opening of the lock on the separator, it is thus possible to realize sustained fire, without making any further manual actions on the shooting system. This results in the advantage of the shooting system according to the invention that it can be operated without an operator must be present during the continuous fire mode.

It is further provided that the tube forms a tube paragraph, where the sleeve can be applied with an end-side paragraph in the gas pressure. By applying pressure to the sleeve in the chamber, the sleeve moves in the direction of the tube closure, and it comes after pressing the spring in a certain travel to rest on the tube paragraph and thus in addition to the translation of the tube, due to the coupling of the tube to the Pipe lock and spindle rotation and nut displacement, also a force on the pipe to Displacement of the tube closure in the opposite direction to the movement of the muffler generated.

For better handling of the shooter is provided that the shooting system has at least one support support on the housing. The support support is designed such that it allows a comfortable support of the shooting system on the shoulder of a shooter and facilitates the relative movement of the shooter for the shooter. When arranging a plurality of support posts they can be formed and arranged so that it allows a stable installation of the shooting system on the ground. In particular, in the continuous fire mode can thus set up the permanent operation of the shooting system without the presence of an operator.

For better alignment of the shooting system is provided that between the support post and the housing at least one joint is arranged, which allows a change in position of the housing relative to the alignment of the support post.

The integration of a fixing device on the joint also makes it possible to turn off the shooting system on the ground and accurately and operate in continuous fire, with a fixed installation of the shooting system on the floor in a simple manner, a change in the shooting angle of the shooting system can be made. Conveniently, two joints between the housing of the shooting system and the support bracket are provided so that a rotation of the shooting system in all three rotational degrees of freedom can be made.

Furthermore, an object of the invention is a method for operating a recoil-minimized shooting system, wherein in explosion of a charge of a projectile in a pipe of the shooting system due to the explosion pressure wave, a silencer in the direction of the projectile to be ejected and a pipe closure in the opposite direction relative to a housing of the shooting system, wherein the pipe is connected to the pipe closure during its removal movement from the muffler such that the pipe is also removed from the muffler. Thus, recoil pulses can be generated in opposite directions in the shooting system and the recoil pulse of the projectile can be canceled.

It is provided that the removal movement of the muffler on the one hand and the pipe and pipe closure on the other hand at the earliest begins when the projectile has passed at least the gas discharge opening, so has covered about two-thirds of the way in the pipe.

Furthermore, it is provided that after reaching a Weg- end position of the pipe closure and the pipe at a maximum distance from the muffler, a solution of the pipe is caused by the pipe closure, so that the tube is moved under the action of a muffler acting force in this direction, whereby the pipe closure is fixed at the maximum distance from the muffler. This process step ensures the opening of a cartridge chamber formed by tube and tube closure.

In addition, it is provided that the pipe substantially causes the lifting of the fixation of the pipe closure when reaching its initial position in the position of the shot readiness, so that it is also displaced in this direction under the action of a force acting in the direction of the muffler. Thus, after opening of the cartridge chamber and removal of the cartridge case from the cartridge chamber by the movement of the tube closure in the direction of muffler, the cartridge chamber are closed again, the kinetic energy of the tube and / or the tube closure for mechanical reloading the shooting device is exploited with another cartridge. Furthermore, a method is provided for manually producing the shooting readiness of a shooting system, whereby a relative movement of two handles arranged on the housing of the shooting system are converted into movements by the sound absorber and pipe and pipe closure, so that the silencer on the one hand and the pipe and on the other hand, remove the pipe closure from each other. This makes it possible to tension springs in such a way that their spring forces can be triggered if necessary and actuate mechanisms, which in turn trigger a new shot. By means of the relative movement of the handles arranged on the housing, the first cartridge can thus be loaded into the shooting system.

The invention will be described with reference to the accompanying drawings. It shows:

FIG.

First, the structural design of the shooting system according to the invention will be described in their individual parts. Subsequently, the description of the dynamic operation of the shooting system according to the invention.

The shooting system according to the invention comprises a housing 1, in which, arranged displaceably relative to the housing 1, a tube or barrel 2 and a tube closure 3 are arranged. The tube closure 3 closes the end of the tube 2 opposite the mouth of the tube 2 in the state of the shot triggering readiness. The return spring 24, which is designed as a spiral compression spring, is located on the tube and concentric with the longitudinal axis of the tube 2. Above the tube closure 3 and the tube 2 is a threaded spindle, which is mounted in its center by means of a flange O in the housing 1. The flange O forms two opposing coaxially arranged support bearings Dl and D2. Coaxial is on the spindle 4 at its two opposite ends in each of sections in which the spindle has no thread, a second coil spring Z is arranged. At a threaded portion of the spindle 4 is a right-hand thread 4b, on which a nut N is arranged, which is designed as an integral part of the pipe closure 3. At the other threaded portion of the spindle 4 is a left-handed thread 4a, on which the nut Nl is arranged, which is designed as an integral part of a muffler 5. The silencer 5 essentially consists of a cylindrical element which surrounds the tube 2 in the ready-to-shoot state and of further housing elements which at least partially surround the spindle 4. Located in the muffler 5, there is a second force-applying device, which is substantially in the core the left-handed threaded portion 4a is arranged. This second force-applying device A consists of a pull rod which is anchored in the muffler at one end, wherein a coil spring is arranged on the pull rod on a flange of the tie rod and coaxial with the longitudinal axis of the tie rod. Analogous to the second force-exerting device A, a second force-exerting device B is arranged in the housing of the tube closure 3. Like the second force-applying device A, this second force-exerting device B consists of a pull rod, on whose uniquely arranged flange a spiral compression spring is supported, wherein the pull rod and coaxially arranged on the pull rod coil spring in the region of the longitudinal axis of the right-hand threaded portion 4b , In the position of the shot trigger readiness, the tube 2 and the tube closure 3 together form a cartridge chamber 27, in which a projectile 30 is arranged when the shooting system is ready to fire.

Arranged in the tube closure 3, located below the spindle 4 is a rocker arm 10 (the lock of the tube with the

Pipe closure), the position of the tube 2 relative to

Pipe closure 3 locked in certain positions of the two components in the housing 1 with each other. At this rocker arm 10th

(The lock of the tube with the tube closure) is coupled to a separator 11, which actuates the rocker arm 10 (the lock of the tube with the tube closure) for the purpose of opening or closing the coupling of the tube 2 to the tube closure 3. Also arranged in the tube closure 3, there is the firing pin 12 and the firing pin compression spring 12 a coupled thereto. Under the pipe closure 3 is the autonomous trigger mechanism 13, 14 with the compression spring 13b and the manually operated trigger mechanism. The autonomous trigger mechanism comprises a first stop 14. Furthermore, located below the pipe closure 3, a fixator 15 of the pipe closure, which is connected to a train coupling, which in turn with a Stop 17 is connected. On the second stop 17, the force of a compression spring 17a acts.

Furthermore, a shoulder 18 is arranged on the housing 1. In the lower part of the housing, there is furthermore a joint 21, to which a support post 19 is articulated via a further joint 20.

In addition, two handles 7, 7a are arranged below the tube 2, wherein in the region of the first handle 7 a release 23 is arranged for releasing the relative movement of the handles 7 and 7a in opposite directions. The relative movement of the two handles 7, 7a is used to manually invite a new cartridge. At the first handle 7 also the trigger 22 is arranged. The first handle 7 is connected via a plunger 7 b with a separator 8 in connection, which is rotatably mounted in the housing 1. The disconnector 8 in turn acts with its rotary motion on a lock 9, on which the force of a lock spring 9a acts.

Further details of the shooting system according to the invention are explained in connection with the dynamic behavior of individual components during firing. For firing from the shooting system according to the invention this is preferably placed with the support post 19 on the shoulder of a shooter, and then activates the release 23, which allows a relative displacement of the two handles 7 and 7a. Subsequently, the two handles 7, 7a are pulled apart in opposite directions. Thereupon, the plunger 7b fixedly attached to the first handle 7b displaces the angular position of the separator 8 via a second driver 7d arranged at the end of the plunger 7b. Its rotation acts on the lock of the entire latch 9 such that a volume element 9b of the lock consists of a recess 3a is tipped out at the pipe closure 3. Contrary to the spring pressure of the lock spring 9b thus takes place the release of the pipe closure 3 for a translatory movement in the housing 1. Due to the relative movement of the Both grips 7 and 7a, the muffler 5 moves towards the mouth of the shooting system and the first handle 7 moves the tube and the tube closure 3 in the coupled state back, that is, in the opposite direction with respect to the movement of the muffler. 5 As a result, the first force-exerting device 24, which consists of a spiral compression spring, tensioned and acts on one side of the tube 2 and on the other side on the muffler 5 at respectively provided on the components flanges. The introduction of the pressure force by the first force-applying device 24 on the pipe or on the muffler 5 can be seen in Figs. Ic and Id. At the same time, the second force-applying devices A and B, which consist of the tie rods and compression springs, stretched, so that in the second force-applying devices A and B fixing nuts N and Nl forces on the pipe closure 3 and the muffler 5 in the direction of these components be exercised in firing position. In order to avoid retraction of the nuts N and Nl on the left or right threaded portions of the spindle 4 beyond the ends thereof, second spiral springs Z are arranged on the threaded portions, the Verschieweweg- limitation of the nuts N and Nl on the threaded portions 4a and 4b of the spindle 4 realize, wherein the second coil springs Z also serve an impact absorption at the end of the spindle sections 4a and 4b.

Due to the displacement of the tube closure and the translational movement of the nut Nl on the spindle section 4a, the non-self-locking spindle 4 is set in rotary motion, as a result of which the nut N also translationally moves on the spindle in the threaded section 4a, so that with the same pitch the two threaded sections 4a and 4b results in a synchronous movement of the muffler 5 and pipe closure 3 in opposite directions.

By locking the tube 2 with the tube closure 3, the tube moves analogously to the tube closure movement also against the movement of the muffler 5 and against the direction of a projectile to be ejected until the separator 11 on the shoulder 18, which is fixed to the housing 1, applies. By the system or the back pressure of the separator 11 on the shoulder 18 of the separator 11 is moved relative to the pipe closure 3, resulting in an unlocking of the coupling connection between the pipe 2 and pipe closure 3 results. Due to the force of the first force-applying device 24 on the tube 2, this shifts after decoupling from the tube closure 3 again in the direction of its initial position in firing position. This process is shown in Fig. Ic.

As a result of the fact that the fixator 15 fixes the tube closure 3, as shown in FIG. 1c, in the stop position of the separator 11 on the shoulder 18, the tube closure 3 remains in this position, so that the tube 2 moves back to the firing position alone. About 5 mm before reaching the firing position of the tube 2 pushes a arranged on the tube 2 driver 2b against the second stop 17. Contrary to the force of the spring 17a on the second stop 17 then moves the second stop 17, so that he pull the coupling 16 acts on the fixator 15 such that it performs a rotational movement. Due to this rotational movement of the fixator 15 this tilts out of a recess on the pipe closure 3, whereby the locking of the pipe closure 3 in the maximum distance from the muffler 5 in the housing 1 is canceled. Due to the effects of the second force-applying devices A and B, the pipe closure 3 also moves in the direction of the mouth of the shooting system, ie in the direction of the muffler 5. By connecting the pipe closure 3 via the nut N to the spindle 4, the spindle 4 again set in rotation, whereby the nut Nl of the muffler 5 is also taken, so that the muffler 5 moves translationally in the direction of tube closure 3. That is, for the same pitch values of the threaded portions 4a and 4b lead after release of the pipe closure 3 of the pipe closure 3 and the muffler 5 synchronously approaching movements. The kinetic energy of the tube closure is used to reload new ammunition into the cartridge chamber 27. When entering the firing position of the pipe closure 3, the separator 11 strikes against the first stop 14, whereby the autonomous trigger mechanism 13, 13b is actuated. The rotatably mounted in the housing 1 tilting element 13 is thereby changed in its angular position. Since the firing pin 12 stuck in the direction of muffler 5 on the tilting element 13 in the movement of the pipe closure 3, it is thus released by the rotational movement of the tilting element 13. However, the firing pin 12 does not shift due to the force of the firing pin compression spring 12a in the direction of the cartridge, but remains due to the prepared by the tilt rocker 13a of the manual trigger mechanism fixing in a cocked position. It then follows the movement of the first handle 7 in its initial position and thus a relaxation of the first force-applying device 24. Also, the second handle 7a returns to its original position, whereby also the second force-applying devices A and B are relaxed. The releaser 23 can be locked again or a determination device 23a can be actuated, which fixes the positions of the handles 7, 7a relative to one another.

The operation of the shooting system according to the invention in the fire mode is described below. After movement of the trigger cock 22, a pull rod T, as indicated in a section in Fig. 12a, pulled in the direction of the mouth of the shooting device, so that a first tooth Tl acts on a second tooth S2 on the tilting rocker 13a. By the tilting movement of the tilting rocker 13 a, a first tooth Sl on the tilting rocker 13 a is moved so that it moves away from the firing pin 12, whereby it is released. The firing pin 12 shoots due to the application of force by the firing pin compression spring 12 a in the explosive charge in the Cartridge chamber 27 located cartridge. This will trigger the explosion of the explosive charge. Under the pressure of the propagating explosive gases, the projectile 30 is fired from the cartridge chamber 27 or from the tube 2 and thus from the shooting system according to the invention. Until the projectile 30 has reached the mouth end of the tube 2, the muffler 5, the tube 2 and the tube closure 3 remain in the firing position. At the exit of the projectile 30 from the shooting gas discharge openings 25 are released, which extend from the interior of the tube 2 in a chamber 26 formed by the tube 2, muffler 5 and sleeve 6. The explosive gas flows into these chambers. Due to the pressure spreading on all sides, the explosion gases press on one side on a wall of the muffler and on the opposite side to a flange 6b of the sleeve 6, whereupon it is displaced by the explosion pressure application of force in the direction of the pipe closure 3 and thereby on the separator 8, as shown in Fig. Ia, acts. The rotation of the separator 8 causes, as described above, a disengagement of a volume element 9b on the lock 9 of the entire lock from a recess on the pipe 2 or pipe closure 3 such that the pipe closure 3 together with the tube 2 from the muffler 5 in the housing. 1 can remove. The further movements of pipe 2, pipe closure 3 and muffler 5 and the nuts N and Nl connected to them and the autonomous release mechanism and the manually actuable release mechanism are as described in the activation process of the shooting system (by relative movement of the two handles 7 and 7 a).

In the following, the detailed description of the invention will be made with reference to the individual drawings. Fig. Ia shows the shooting system according to the invention in the state in which the firing pin 12 pushes into the cartridge of the projectile 30, but the projectile has not yet left the sleeve. An explosion of the explosive charge is generated. FIG. 1 b shows how the projectile 30 moves away from the pipe closure 3 when the explosive gases are pressurized. The explosion gases spread on all sides in the tube 2, so that they pass through the gas discharge openings 25 into the chamber between the tube 2, muffler 5 and sleeve (jacket) 6. It can be seen that the plunger 7b and the sleeve 6 have shifted in the direction of the pipe closure 3, that they have tilted the separator 8 so far that this has also caused a tilting movement of the lock 9, so that a release of the tube 2 or Pipe closure 3 is done in the housing.

In Fig. Ic, the state of the shooting system is shown, in which the projectile 30 has already left the shooting facility, and have due to the spreading on all sides exploding gases of the muffler 5 and the pipe closure 3 and 2 pipe away from each other. It can be seen that the coupled to the muffler 5 nut Nl and coupled to the pipe closure 3 nut N have moved on the spindle 4 to the end portions so that they come to rest on the second coil springs Z. In this case, the first coil springs 29 have tensioned in the second force-applying devices A and B. Furthermore, the first force-exerting device 24, which is arranged on the tube 2 or on the sleeve 6 and which is designed as a compression spring, has likewise likewise been tensioned.

The explosion gases act on the muffler 5 and on the tube 2 or on the tube closure 3 such that they move away from each other. Due to a pitch in the threaded portions 4a and 4b of the spindle 4, which prevents self-locking of the spindle in tensile or Druckkraftbeaufschlagung the nuts N and Nl in the spindle longitudinal direction, a displacement of the nuts N and Nl on the spindle is possible, the spindle is set in rotary motion, so that at the same slope value of the spindle sections 4a and 4b, a synchronous movement of the muffler 5 in the one and of the tube 2 and tube closure 3 in the other direction. Upon reaching a maximum distance of the pipe closure 3 from the muffler 2, the separator 11 abuts the shoulder 18 at. Thereby, the rocker arm (ie the lock of the tube with pipe closure) 10 is moved, so that it is pivoted out of a recess 2a in the pipe. Thus, the coupling between pipe 2 and pipe closure 3 is released. Under the action of the force of the first force-applying device 24, the tube 2 moves again in the direction of the firing position, that is, it moves toward the muffler 5. In this case, the cartridge chamber 27 formed by the tube closure 3 and the tube 2 is opened, so that a sleeve of the cartridge can fall out. Shortly before reaching the firing position of the tube 2 pushes this with an integrally formed on the pipe 2 driver 2b against the second stop 17, which thereby against the spring 17a in the direction of Silencer 5 is moved, whereby it generates by its movement a train in the train coupling 16, which then tilts the fixator 15 of the pipe closure in a position from which it is removed from a recess in the pipe closure 3. This causes the release of the tube closure 3, so that the tube closure 3 also returns to the silencer 5 under the influence of the second force-exerting devices A and B and also when the first force-exerting device 24 is exerted on the silencer 5. In the return movement of the tube closure 3 in the firing position, its kinetic energy is used to load a new cartridge into the cartridge chamber 27.

In Figs. 101 to 108 of the trigger mechanism of the shooting system according to the invention is shown. After the return movement of the tube closure 3 in the firing position, as shown in Fig. 101, due to the overlap of the tilting rocker 13a and its first tooth Sl with the firing pin 12 this remains in a cocked position in Housing fixed. That is, the firing pin 12 is stretched over the deflection of the firing pin compression spring 12a and is held by the first tooth Sl on the tilting rocker 13a. After actuation of the trigger 22 (not shown in FIGS. 101 to 108, but indicated by an arrow), the pull rod T is displaced in the direction of the silencer 5. An integrally formed on the pull rod T carriage on which the first teeth Tl and T2 are arranged, also shifts in the direction indicated. In Fig. 101 it is shown that the first tooth Tl comes to rest on the second S2, whereby the tiltable rocker 13a arranged rotatably in the housing 1 is changed in its angular position. In Fig. 102, the state is shown shortly before release of the firing pin 12. In Fig. 103 it is shown how the firing pin 12 shoots under the force of the firing pin compression spring 12a in the direction of the cartridge. During further movement of the pull rod T in the direction of the muffler 5, the second tooth S2 slides over the first tooth T1, so that the second tooth S2 is located between the two teeth T1 and T2. The firing pin 12 strikes, as shown in Fig. 104, in the cartridge and generates the explosion of the cartridge disposed explosive charge. The movements of the components silencer 5, pipe 2 and pipe closure 3 are carried out as indicated above. The second tooth S2 is still between the two teeth Tl and T2 on the pull rod T. After again made return movement of the pipe closure 3 in the firing position of the firing pin 12 remains hanging on the tilting rocker 13 and the first tooth Sl. Upon further displacement of the drawbar T in the direction of the muffler 5 by further movement of the trigger 22, the second tooth T2 comes to rest against the second tooth S2. It is thus again the release of the firing pin 12, as shown in Fig. 106, triggered, with a new shot is fired. In the fixation of the drawbar T in the specified position by means of the determination device 23a or other means a continuous fire mode is adjustable. This means, the shooting system according to the invention shoots continuously, without further operation by an operator. When canceling the continuous fire mode, the trigger cock 22 is released, so that, as shown in Fig. 107, the pull rod T moves in the opposite direction. Due to the one-sided rotational mobility of the first tooth Tl on the pull rod T, the second tooth S2 presses against the tooth Tl, so this is rotated against the force of the compression spring 13c, so that the pull rod T move under the tilt rocker 13a in the direction of the paragraph 18 can. In Fig. 108 is shown how the first tooth Tl almost completely flaps around to allow the complete displacement of the drawbar T in the state of the firing position.

The individual parts are explained below with reference to the individual part representations.

In Fig. 1, the housing 1 is shown, in which fixed the paragraph 18 is integrated to the system of the separator 11. Fixed to the housing 1, is located on the underside of the support post 19, which is connected via two joints 20, 21 on the housing.

Fig. 2 shows the tube 2 of the shooting system according to the invention in front and side view. At the front end of the tube are gas discharge openings 25. At the rear end of the tube is a section with a larger diameter than the diameter of the front section. In this section with a larger diameter is a recess 2e, which is in the locked state of the shooting system with the lock of the entire lock 9 in engagement. The opposite is a recess 2a arranged, in which a rocker arm 10 engages in the locked state. Furthermore, located at a rear outer edge portion of the tube 2 of the driver 2b, which cooperates when returning the tube to the starting position with a second stop 17. In Fig. 3, the pipe closure 3 is shown, on the underside of which the recess 3a is located, in which engages the volume element 9b of the entire lock in the locked state. At the top of the tube closure 3 is the nut N, which moves on the spindle 4 in its longitudinal axis. Fig. 4 shows the spindle 4 having two threaded portions 4a and 4b. The spindle 4 has a bearing in its center. At its end, it has flanges 4c and 4d for supporting the second coil springs Z. The spindle is hollow in its two threaded portions 4a and 4b, thus providing space for the arrangement of the second force applying means A and B. The two threaded sections 4a and 4b have threads that are oriented in different directions. That is, one of the two threaded portions 4a has a left-hand increase, and the other threaded portion 4b has a right-hand gain, or vice versa. It is preferably provided that the pitch value of the two threaded spindle sections is the same, resulting in a synchronous movement of the nuts N and Nl coupled to the spindle.

Fig. 5 shows the muffler 5, on which the nut Nl is arranged for engagement in the threaded spindle section 4a. On the underside of the muffler 5 there is a third driver 5a, on which the second handle 7a acts when the handles 7 and 7a are pushed apart. In the area surrounding the tube 2 of the muffler 5, this has an inner shoulder 5b. On this inner shoulder 5b, the sleeve 6 acts.

This sleeve 6 is shown in Fig. 6. In addition to its essentially cylindrical construction, it also comprises an end side

Paragraphs 6a and 6b. The paragraph 6b is used to train the

Chamber 26 and to rest on a paragraph on the pipe 2 and the

Paragraph 6a is for attachment to the inner paragraph 5b on

Silencer 5. By means of these paragraphs 6 forces can be transmitted from the sleeve to the muffler or to the pipe which force these components to translational movements.

In Fig. 7, the first handle 7 is shown, to which one side of the plunger 7b connects, which has at its end the first driver 7d. This first driver 7d presses upon activation of the shooting system against the separator 8 of the castle. In Fig. 7a, the second handle 7a is shown, which has a paragraph which acts on the third carrier 5a on the muffler with relative movement of the two handles 7 and 7a. In Fig. 8 the disconnector of the lock is shown, which is arranged rotatably in the housing 1.

9 shows the lock of the entire lock of the shooting system, which brings about the first shot solution when actuated. Actuated by the separator of the lock 8, the volume element of the lock 9b is pivoted out of the recess 2e in the tube and the recess 3a in the tube closure, so that the tube 2 and the tube closure 3 in the housing 1 can move as described.

Fig. 10 shows the rocker arm 10 which is also rotatably disposed at its one end in the housing 1, and the pivoting movement, the coupling between the tube 2 and the tube closure 3 dissolves.

Fig. 11 shows the separator of the system 11, the one-sided

Swivel joint for attachment to the rocker arm 10 (the lock of the pipe with pipe closure). In Fig. 12 is the

Firing pin shown having a slope 12 b, the

Sliding over the tooth Sl in the movement of the distance from

Silencer 5 allows. Fig. 13 shows the tilting element of the autonomous release mechanism, which is rotatably mounted in the housing 1.

13a shows a partial view of the manually actuatable trigger mechanism with the pull rod T, the first tooth T1, the second tooth T2, the tilting element 13 and the teeth S1 and S2 arranged on them. In Fig. 14, the first stop 14 is shown, on which the

Trenner 11 when retracting the pipe closure in the

Schussauslöseposition comes to rest, and is connected via a gear with the tilting element 13.

Fig. 15 shows the fixator 15, the swinging out of the pipe closure 3 causes the release of the pipe closure 3. FIG. 16 shows the tension coupling 16, which is arranged between the fixator of the tube closure 15 and the first stop 14. In Fig. 17, the second stop 17 is shown, which is connected via a hinge at its end via a gear with the fixator of the pipe closure 15. The paragraph on the second stop 17 is used to rest the compression spring 17a, against the spring force, the second stop 17 moves when the driver 2b on the tube 2. In Fig. 18 the paragraph 18 is shown in an enlarged view, on which the separator 11 during opening movement, that is, during a movement of the pipe closure of the tube 2, in which they remove from the muffler 5 comes to rest.

FIG. 19 shows the support support 19 for supporting the shooting system on the shoulder of a shooter. The support bracket 19 is doing with the two coupled joints 20 and 21, which are shown in Figures 20 and 21, on

Housing 1 attached so that pivotal movements for setting a shooting angle and lateral pivoting movements are possible.
