Description

Weapon with recoil damping

The present invention relates to a handgun, in particular a grenade weapon or a so-called attachment with a lafettierten in a housing assembly barrel assembly and a recoil damper assembly which acts between the housing assembly and barrel assembly.

Directional information such as front, back, up, down, right and left are from the perspective of a shooter holding the weapon in the attack.

Especially for large caliber handguns, it is known to provide lafettierte barrel assemblies to reduce the occurring recoil effects on the shooter. From EP 0 911 599 Bl it is known, for example, to provide a flexible barrel in which a recoil damper arrangement acts as an elastomeric spring assembly between the housing assembly and the barrel assembly, and surrounding the barrel assembly is disposed within a guide tube associated with the housing assembly ,

From US 4,689,912 a hand-held high-speed grenade launcher is known, in which also the barrel is lafettiert with respect to the housing. The recoil damping takes place here over the barrel surrounding and acting between this and the housing plate spring packets.

In the known Lafettierungen there is the problem that the arranged around the barrel assembly recoil damper or

Buffer arrangements must either be made relatively long (see EP 0 911 599 B1) or, in the case of a short, compact design, tion, the space around the already large-caliber run around in addition (see US 4,689,912). Both are undesirable.

From DE 717 000 a rifle grenade launcher with a recoil brake or recoil damper assembly is known in which the launcher tube is mounted longitudinally displaceable. The recoil brake may be a rubber buffer, a spring or a liquid brake and is arranged axially between a shock-absorbing portion of the launcher tube and a support portion of a frame assembly.

In particular, in such handguns, in which garnet ammunition or intelligent garnet ammunition is fired, and may have a transverse to the axis of the swing-out barrel assembly, such known Lafettierungen are not or only with considerable constructive or manufacturing effort to realize. Therefore, such handguns (see, for example, DE 10 2005 019 594 Al), so far only without Lafettierung and without recoil damping have been realized.

For modern handgun systems but there is an increasing demand, instead of the usual grenade ammunition with a projectile pulse of about 13 N / s to shoot those with higher projectile pulses of 25 N / s or above, and this in a caliber range of 25 mm to 40 mm. But such projectile impulses are difficult to tolerate without effective Lafettierung for the shooter.

On this basis, it is the object to provide an improved Lafettierung in conjunction with an effective recoil damper assembly. Another object may be seen to provide a compact handgun with a recoil damper assembly which is capable of high Projectile impulses (25 N / s and more) and / or large caliber (25 mm and more) is suitable as well as easy to use (swing-out barrel) and easy to maintain or can be converted (replaceable barrel assemblies).

This object is fulfilled by the handgun according to claim 1, which can be embodied in particular as a grenade weapon or as a so-called attachment, and can be used independently or with another weapon (for example automatic rifle).

The invention is characterized in that the recoil damper assembly is disposed axially between the shock bottom portion of the barrel assembly and a support portion of the housing or frame assembly, wherein the recoil damper assembly is penetrated by a firing pin guide; This measure makes it possible to separate the Lafettierung - the linear Laufführung / - recording - spatially and functionally from the recoil damping. In this way, the running assembly can be made simpler and additional functional features of the run assembly can be realized with less design effort (operability, ease of maintenance, interchangeability of functional elements). The recoil damper arrangement or the buffer arrangement is thus largely independent of the most important running functions (cartridge receiving, bullet guidance). The space thus gained around the barrel is thus available, for example, for data transmission devices (programming coils) which are necessary in connection with so-called intelligent ammunition. Thus handguns may also be suitable for exceptionally large calibers (40 mm and more) and high projectile impulses without the space requirement growing impermissibly transversely to the axis of the soul. The invention enables a compact, slim, versatile and usable handheld Firearm with effective recoil damping, which can be provided with further advantageous features.

According to claim 2, the barrel assembly is arranged in a receptacle that fulfills two functions: It takes over the running or Lafettierung without this would have to absorb high forces, since the shock absorber assembly is realized independently of this Lafettierung. At the same time, this receptacle - and thus the barrel itself - is pivotable about a pivot axis extending perpendicular to the axis of the soul between a reloading and a firing position. This swiveling arrangement has proven itself especially when reloading grenade weapons. When the barrel is swiveled out, the cartridge storage area is easily accessible for reloading. Depending on the design of the weapon, the barrel can be swung out laterally to the right or left or laterally upwards or downwards for reloading or for removal of the cartridge case. This flexibility is particularly advantageous in so-called attachments that are attached to another weapon. Namely, the handgun according to the invention can be arranged below or laterally on any other weapon. The pivoting of the barrel can be set up so that the necessary handles for reloading the weapon can be performed even with a weapon held in the stop, without the shooter would have to change his body position or the weapons position significantly.

According to claim 3, the recoil damper assembly comprises an elastomer spring assembly. Such elastomer springs are particularly easy to adjust with regard to their spring and damping properties and are also largely insensitive to external environmental influences. Proven materials include polyurethane foams or other elastomer materials. The claims 4 to 6 relate to advantageous embodiments of

Firing pin guide and tee mechanics in conjunction with the recoil damper assembly. The firing pin guide passing through the elastomer spring arrangement simultaneously assumes a guiding function of the spring arrangement and optionally forms a friction surface pairing with a spring arrangement that additionally advantageously influences the damping effect.

An acting between the firing pin guide and the housing assembly bounce element according to claim 4 attenuates the stop of the leading barrel assembly or the Rückstoßdämpferanordnung when it returns to its normal position. With this measure, both the recoil itself and the subsequent flow are effectively damped. The ease of use of the weapon is significantly improved and the mechanical stresses on the moving weapon parts are reduced.

5

According to claim 5, the firing pin guide acts in the recoil effect so on a knock-off (hammer or cock), so that it is brought into its cocked position. The hammer does not need to be cocked manually, but the weapon is immediately ready for use immediately after reloading.

The claims 6 to 9 relate to advantageous designs of the impact floor or a shock-absorbing element, which is designed according to claim 6 as a cartridge bearing cap, which is pivotable about a parallel to the axis of the axis pivot axis between its open and its closed position. The shock-absorbing element is thus pivoted in the impact plane and can thereby safely and tightly close the cartridge chamber in conjunction with easy-to-design support flanges. The swing hinge itself does not have to absorb any shot loads. The training of claim 7 ensures that the shock bottom with properly inserted ammunition always assumes its closed position when the barrel assembly is pivoted into its closed position. The axially resiliently disposed in the shock bottom element firing pin allows complete decoupling of the barrel assembly of the recoil damper assembly. The trained according to claim 9 interface level improves this decoupling and provides a largely backlash-free load transfer between the barrel assembly with shock bottom element and recoil damper assembly and thus with the housing assembly safely.

The further developments according to claims 10 and 11 ensure the secure locking of the barrel assembly in the firing position, wherein in the embodiment according to claim 11, the locking is to be ensured even if the spring effect in the detent arrangement by damage or contamination reduced or complete should have failed.

According to claim 12 barrel assemblies of different Ka over can be added. Thus, a handgun according to the invention can cover a very large ammunition spectrum.

According to claim 13, a coupling device or an interface for coupling to other weapons is provided. This is an armament assembly according to claim 14 to realize in which the handgun according to the invention is designed as a so-called attachment and in particular as a grenade weapon.

An embodiment of the present invention will now be explained with reference to the drawings. Showing:

Weapon.

Structure and basic functions of a weapon 1 according to the invention are described below with reference to FIGS. 1 and 2.

The weapon 1, as an essential housing assembly on a main frame 2, which has a plurality of interfaces 4a to d, which serve to attach the weapon 1 to another weapon (not shown). The weapon 1 can be hooked, for example, at the interface 4d and then connected via a locking pin with a corresponding receptacle on the carrier weapon (for example, at the gas loss). On the main frame is still a housing element 6 with handle 8, deduction area 10 and the tee 12 are arranged. The connection of the housing assembly 6 also takes place via corresponding locking pins 14. At the bottom of the main frame a Picatinny rail 16 is formed.

The main frame 2 forms the spine of the weapon and receives in its interior (FIG. 2) the barrel assembly 20 and the recoil damper assembly 50. On the right side of the frame by a wall 18 is closed (see Fig. 7) and at its front end, it has a pivot fork 19, in which the Lafettierhülse 22 is pivotally received via hinge pin 24. On the left side, an electronic unit 26 is provided on the barrel assembly 20 as a cover, which can be swung in and out together with the barrel assembly 20 (see also FIGS. 3 and 4). At its rear end face, this electronic unit has display and control elements 26a which serve to provide programmable ammunition 5 located in the run 21 with corresponding function and / or target data.

The barrel 21 is guided over its mouth end in the Lafettierhülse 22. Serves a screwed onto the mouth guide sleeve 23 to which a Vorholfeder 25 attaches, which is supported on a shoulder 27 and so the barrel 21 pushes forward into the Lafettierhülse 22 and against a buffer ring 28 provided there. On the run 21, a pivot spring 30 engages, which is supported on the main frame 2 and the run assembly 20 about the hinge pin 24 swings laterally (see Fig. 3 and 4) when the locking of the barrel assembly 20 is solved with the main frame 2. At its rear end, the barrel 21 in the cartridge storage area 32 is screwed to a closure assembly 40 (see also FIG. 5). The closure assembly 40 includes a closure block 42 in which a pivot bottom 44 is arranged, which is parallel to the Axle axis 3 extending pivot axis 45 can be pivoted out of the closure block 42 when the barrel assembly 20 is in the pivoted position (Fig. 3 and Fig. 4). In the pivoted-out position, the pivot bottom 44 exposes the cartridge bearing 32, so that ammunition can be introduced into the barrel. This position is shown in Fig. 3. In its closed position, the pivot bottom 44 serves with its inner side as a shockbottom which is fixed in the direction of the axis of the soul in the edge region 46 by a corresponding retaining flange 47 in the closure block. In the pivot bottom 44, the firing pin head 49 is received axially via a leaf spring 48.

Breech block 42, pivot bottom 44 and firing pin head 49 each border with their rear free end faces in a plane 50 to the recoil damper assembly 60 which is coupled in the pivoted position of the barrel assembly with the shutter block 42, and thus the lafettierten barrel 21.

The recoil damper assembly 60 includes a cleat 62 from which extends rearwardly a guide sleeve 64. The guide sleeve 64 receives in its interior the firing pin guide 65, which is closed at the rear end with a control head 66 which is screwed into the guide sleeve 64. The firing pin 68 is spring-loaded between the firing pin guide 65 and the adjusting head 66 clamped so that its front end in the plane 50 an opening in the cleat 62 passing through the firing pin 49 abuts. The rear end of the firing pin 68 protrudes from a corresponding hole in the adjusting head 66 addition.

Between the rear surface of the cleat 62 and a likewise formed on the main frame 2 support portion 5 extends the recoil spring 70 which surrounds the guide sleeve 64. The recoil spring 70 is formed as an elastomer spring, the alternately arranged, annular guide 71 and damping elements 72 has. The guide elements 71 are made of metal or plastic and the damping elements 72 made of an elastomer material, in particular of a PU foam material.

On the rear end of the firing pin 68 acts in a known manner, the knock-off mechanism 12 with its spring-loaded hammer 13, which is triggered via the trigger 11. The triggered hammer 13 strikes the firing pin 68 forward, which strikes with its front end through the clapper plate 62 on the firing pin 49, which ignites with its firing tip through the pivot bottom 44 through the ammunition located in the barrel 21. The propellant catapults the missile from barrel 21 - hopefully towards the target.

The recoil action pushes the cartridge bottom back against the inside of the pivot bottom 44, which acts through the edge lock 46, 47 on the closure block 42. The closure assembly 40 pushes the rebound damper assembly 60 rearwardly in the plane 50 against the support portion 5 on the main frame 2 via the cleat 62. The damper members 72 of the recoil spring 70 are compressed and the annular guide members 71 slide along the outside of the guide sleeve 64. The deformation of the recoil spring 70 damps the recoil elastic by the hysteresis effect of the damping elements 72. An additional damping effect is possibly effected by the friction of the damping elements 72 on the outside of the guide sleeve 64.

In the recoil movement moves the barrel 21, the

Lock assembly 40 and the recoil damper assembly 60 to the rear in the main frame 2. This moves the rear End of the guide sleeve 64 through the opening in the support area 5 to the rear and presses over the control head 66 against the hammer 13, which is brought back into its cocked position. In this position, a safety shaft 15 can be rotated over a safety lever so that the optionally unlocked hammer 13 can no longer hit the rear end of the firing pin 68.

After the actuator head 66 has reached its rear reversal point, the recoil spring 70 attaches to the cleat 62 attaching the closure assembly 40 and the barrel 21 again forward to the starting position. This dampens that

Ring spring element 74 the impact of the adjusting head 66 against the

Supporting portion 5 and the buffer ring 28, the impact of the guide sleeve 23 at the front end of the Lafettierhülse 22 in

Mouth area.

For reloading, the barrel assembly 20 is unlocked and laterally swung out (FIGS. 3 and 4). In this case, the spring 25 keeps the barrel 21 in the starting position and the pivot spring 30 holds the barrel 21 in the pivoted position.

For reloading the pivot bottom 44 is pivoted down out of the retaining flange 47 of the closure block 42, so that the cartridge storage area 32 is accessible. The empty cartridge case is removed and a new cartridge is reloaded. Before swiveling in, the swiveling bottom 44 can either be closed manually and the run assembly 20 can then be pivoted in again. But it is also enough to turn only the barrel assembly 20. In this case, the lower edge 44a of the pivot bottom 44 abuts an edge 2a of the main frame 2. The edge 2a causes the pivoting of the running group 20 at the same time pivoting the pivot bottom 44 in its closed position. This ensures in a simple manner that the pivot bottom 44 pivoted Running assembly 20 always its properly closed

Position assuming that the ammunition is properly inserted into the cartridge chamber 32, or the cartridge chamber (32) is empty (see Fig. 4).

The locking of the barrel assembly 20 via a spring-loaded in the closure block trap 80, which locks when pivoting the barrel assembly in a corresponding recess in the main frame 2. If the spring action of the detent spring 82 should not be sufficient for proper locking, the latch 80 may be inserted into the lock via the locking slide 84 (see FIGS. 5, 6, 7 and 8) via the pin 86 (FIG locked position to be moved. In this case, a locking lug 88 protrudes inwardly from the side wall 18 of the main frame 2 and presses on the upwardly projecting from the closure block 42 bolts 86 (see Fig. 3, 4 and 5). The position of the lock slider 84 also indicates to the shooter whether the weapon is properly locked (Figure 6).

To unlock the pivot lever 90 (FIG. 7), which engages from below on the latch 80 and is arranged around the pin 92 transversely to the axis of the soul 3 pivotally mounted in the main frame 2. To actuate the button 94, which protrudes down into the trigger area 10 and can be operated there for unlocking with the trigger finger. When unlocking the Entriegelungslasche 96 acts on the release lever 90 on the case 80 and pushes them up from their rest.

In order to limit the pivoting of the unlocked barrel assembly 20, the stop 100, which is also received transversely to the axis of the soul 3 rotatable in the main frame 2 serves. In its first rotational position, the protruding edge 101 of the head 102 projects into the pivoting path of the barrel assembly 20. At the opposite end, the stop 100 holds a spring catch 104 in this position. For complete disassembly of the barrel, the stopper 100 can be rotated by 180 °, so that the flat side 106 then releases the pivoting path of the barrel assembly 20.

The main frame 2 is dimensioned so that it can accommodate different barrel assemblies. For example, alternate barrel assemblies for 25 mm or 40 mm caliber can be used. The interfaces of the different closure modules to Rückstoßdämpferanordnung are also carried out the same. Optionally, the recoil spring 70 can be replaced according to the pulse of the ammunition used.

The weapon 1 can be used by itself. The attachment interfaces 4a-d can then be used, for example, to attach an additional shoulder support and possibly also additional sighting device to the weapon 1. But it can be used together with a standard (not shown) rapid-fire weapon, to which it is then coupled via the interfaces 4a-d. The weapon according to the invention is thus part of a very flexible weapon system and versatile.

Further advantages and embodiments will be apparent to those skilled in the following claims.
