Description

The The invention relates to a closure system comprising a kind of block closure for in particular foreign or self-powered small and Medium-caliber weapons.

From the prior art, various drives such as foreign or self-propelled weapon systems are known. In third-party drives electric drives are often provided, which then drive, for example, a chain. A well-known chain drive is used in the known under the name Bushmaster or Chain Gun automatic cannon. Here, necessary downtime for closing the shutter, for the firing of the shot, for opening the shutter and the presentation of a cartridge before closing by a rotating, driven by a motor chain realized ( http://de.wikipedia.org/wiki/M242_Bushmaster ). The closure with the preceding ammunition or cartridge is thereby fed linearly to the cartridge chamber.

In the DE 10 2006 022 622 A1 a linear supply of the ammunition is described in a gun barrel or cartridge chamber, which has a control link used for function control in the horizontal plane parallel to the path of a straight-to-leading closure of the closure weapon. For a locking of the closure, a locking link is provided, which is incorporated in the movable slide. In this locking link can engage a bolt preferably a weapon side arranged locking ring. This bolt in turn then moves the locking ring.

A feature control for a drum weapon is not subject to public release DE 10 2008 015 892.5 , Here, a function control is also realized by means guided in scenes connecting rod. The function control itself includes the feeding of an ammunition into the drum or the respective cartridge chamber and the circuit of a drum for adjusting selbiger.

A locking centering of a self-loading handgun is the DE 199 07 967 B4 removed and has a rotatably locked closure with warts, which is ver slidable in the longitudinal direction of the weapon for driving and for inserting a cartridge into a chamber. The closure has a closure head by means of which the closure is functionally connected by rotation with the barrel.

With the DE 196 00 459 A1 a closure for a firearm is proposed, which unlocks the locking head from the locking piece of the gun barrel end and locked during the forward movement during a backward movement of a chamber handle. The closure head has warts obliquely to the axis, whereby a rotational movement is caused during the unlocking and locking operation of the closure head from the Verrieglungsstück the barrel. The Weitern is a Drehkammerverschluss from the DE 292 22 251 U1 known.

Information about a self-loading handgun with a movable shutter with locking lugs on the bolt head can also be taken from the DE 199 03 322 B4 be obtained. The closure consists of a closure carrier and the closure head, which is mounted rotatably and longitudinally movable on the closure carrier. The warts are arranged circumferentially distributed at corresponding placement points on the closure head. The barrel sits with its rear end in a sleeve, at the end of a ring of longitudinal grooves is formed, which open into an annular groove adjacent to a chamber. The locking lugs of the closure head slide when closing along the longitudinal grooves of the sleeve and run after turning the closure head in the annular groove.

The Present solutions have in common that either one Rotary movement of the closure head or a locking ring or the like in the process of closing as well as opening of the closure must be included.

Tipping rifles with a block closure, for example, with the DE 10 2007 044 993 B3 as well as with the DE 199 09 580 B4 published, wherein the running unit is arranged in each case tiltable.

A vertical locking system for another Kipplaufwaffe is with the DE 44 39 054 B4 proposed.

From the field of large caliber weapons wedge closures are known with a rear side of a gun barrel arranged bottom piece, such as in the DE 10 2004 052 550 A1 or DE 695 05 951 T2 ( EP 0 747 651 B1 ) or DE 199 28 277 C2 described.

The Invention has set itself the task of a simple closure system especially for a foreign or self-powered weapon show what also in an advantageous manner, even space-saving is constructed.

Solved The object is achieved by the features of claim 1. Advantageous Embodiments are listed in the subclaims.

The invention is based on the idea that To put closure or closure carrier by a wedge-like block which is displaceable approximately vertically to the closure and thus to lock it, so that a form fit is produced between the weapon housing and the closure or closure carrier. As vertical, all directions are to be regarded, which are possible weapons technology, such as vertically from below, vertically laterally, vertically from above.

Of the preferably block-like executed locking slide has at least one nose-like projection, with which the locking slide in a matching recess of the closure or closure carrier can intervene positively. The nose (s) should be there have a relatively steep flank to the barrel and can at the but fall slightly off the other flank. Preferably, an easy oblique integration of the recesses (towards the weapon barrel) shown in the closure or fastener carrier, through this construction a larger power input the recoil is possible. Therefore, will the locking slide preferably obliquely forward in Weft direction slidably guided into the recesses into it.

Of the Block can be integrated laterally on the weapon housing, why the housing narrower than the closure or closure carrier should be so that the extension can intervene in the recesses. Preference is given to a bilateral lateral integration. alternative but it is also conceivable a central position of the block.

The Lock movement is by a to the weapon housing (longitudinally) movable Sliders realized and controlled in the for the downtime for closing the closure, for firing the shot, for opening the closure and presenting a cartridge in front of the shutter needed times in the form are involved by scenes or curves. The for the Closing motion responsible backdrop acts with at least a fixed curve, for example, integrated in the weapon housing, functionally together. Another, with the Verschiebekulissen cooperating Setting serves for horizontal adjustment of the block. The slider should be parallel, in the preferred embodiment vertical be aligned to the weapon housing.

Of the Slider is in continuation of the idea preferably U-shaped executed so that he embrace the weapon housing can and a stable locking system is created and the slider with its both sides of the closure or closure carrier existing scenes can be moved by a drive. Possible but it is also a slider on each side of the gun case to attach so that both functional, but not firmly together are connected. The block as well as the shutter will be in both Variants positively controlled by the bilaterally integrated curves.

Based an embodiment with drawing, the invention be explained in more detail. It shows:

1 a schematic and only partial view of a supplied closure with slide and scenes,

2a Movements of the shutter feed,

3 a representation of the shot firing with hidden parts.

In 1 is a shutter feeder 1 for a weapon system shown only schematically 2 with a gun barrel 3 , a closure 4 as well as a closure carrier 5 demonstrated. With 6 is a movable approximately vertically in the direction of the running axis locking slide, with at least one nose 7 in at least one corresponding recess 8th of the lock 4 or of the closure carrier 5 for locking the lock 5 at the barrel 3 intervenes. Be beneficial two to three noses 7 on the locking slide 6 proposed. The preferably block-like locking slide 6 is preferably laterally relative to the weapon housing 10 aligned.

Opposite the weapon case 10 is a parallel aligned slider 11 with scenes 12 . 13 movably mounted. This effect the scenery 12 as supply gate the supply of the shutter 4 and the scenery 13 as a slider curve moving the locking slide 6 , This is the locking slide 6 by means of a bolt or connecting rod 15 in the scenery 13 guided. With the feed gate 12 of the slider 11 Functionally working together is a fixed backdrop 14 , as another Zuführkulisse. The curve 14 can in the weapon case 10 to be involved. The common functionality is through another connecting rod 16 allows one end with the fastener carrier 5 connected and with the other end in both scenes 12 . 14 intervenes.

The different backdrops of the scenes 12 . 13 . 14 arise from their task. This clearly shows that the slider curve 13 a long straight slide section 13.1 having. this section 13.1 defines the time of the open lock slider 6 , The shorter section of scenery, on the other hand 13.2 the slider curve 13 includes the lock time, ie, the time in which the shutter 4 remains locked until the shot is fired. Involved here is an internal return option, so the gun barrel 3 and the Ver Enough 4 are floating. The straight scene section 12.1 the supply gate 12 determines the rear downtime of the shutter 4 for feeding the ammunition (ammunition supply time). At this time, the slider can 11 continue driving due to an overstroke, the discarded connecting rod 16 remains in the angled rear end 14.2 the curve 14 ,

The shutter feeder 1 should be on both sides of the gun case 10 be provided, for example in the form of two sliders 11 , The slider (s) 11 are connected to a non-illustrated external drive (via a bolt V) and / or a self-propelled (via a gas piston linkage G, only indicated here) such that this (e) is moved by the respective drive (will). As already mentioned, a U-shaped encompassing of the common slider is preferred 11 around the weapon case 10 What a simple (central) connection of the drives to the slider 11 allows.

The essential movements and interactions of the scenes or feeds 12 . 13 . 14 are in the 2a to d recorded, the representation for the purpose of illustrating the processes carries only an exemplary character and refers in a perspective manner to one side of the system.

In 2a indicated is the locking of the closure 4 , The noses 7 of the locking slide 6 fully reach into the recesses 8th of the lock 4 , The connecting rod 16 is in the ascending end 14.1 the scenery 14 as well as in the longitudinal section 12.2 the scenery 12 ,

With moving the slider 11 to the rear to open the shutter 4 slides the connecting rod 15 of the locking slide 6 along the scenery 13 down in the gate section 13.1 while the connecting rod 16 in the short slide tour 12.2 and in the end 14.2 the scenery 14 remains, so the shutter 4 is not moved ( 2 B ). With entrance of the connecting rod 15 in the lower part of the scenery 13.1 and thus completed unlocking the closure 4 (nose 7 are from the recesses 8th pulled and give the closure 4 free), the connecting rod slides 16 cut into the backdrop transition between the Kulissenab 12.1 . 12.2 and gets through the slider 11 and the fixed slide guide 14 along this constraint (the backdrop 14 ) together with the closure 4 or fastener carrier 5 pushed behind ( 2c . 2d ). For the ammunition feed not shown slides the connecting rod 16 in the lower part of the scenery 12.1 , so while the slider 11 along the connecting rod 15 . 16 but not the shutter 4 can be adjusted. This will be together with the connecting rod 16 stored. The slider 11 However, in turn, during the time of ammunition supply (presenting the ammunition 21 in front of the shutter 4 ) continue. The connecting rods 15 . 16 are as long as, with the forward movement of the slider 11 the corresponding curve sections to the connecting rods 15 . 16 attack and this forward towards the barrel 3 move.

3 shows a representation of an integrated in this construction in an advantageous manner Zündauslösung with fuse.

One with 20 marked primer one in the barrel 3 placed and from the shutter 4 transported cartridge 21 gets through in the clasp 4 integrated firing pin 22 pierced and ignited.

The firing pin or Zündnadelauslösung for single fire, single sustained fire or continuous fire is conventional, for example, magnetic / electric and is in this case via a kinematics 30 stimulated.

The kinematics 30 is composed of a rocker-like manner about a pivot point D mounted first lever 31 , a second lever mounted around another pivot point R 32 in interaction with a hammer 33 together. This is movable by a spring force, not shown, about its pivot point S and with a firing pin system 34 in the lock carrier 5 functionally connected in a manner not shown. The first lever 31 the kinematics 30 is functional with the locking slide 6 coupled.

The function is generalized as follows:
Will the lock 4 through the locking slide 6 safely subordinated and locked, grab the nose 7 in the recesses 8th of the lock 4 , In this case, it works with the locking slide 6 connected levers 31 such that he has the second lever 32 from the hammer 33 pull away and this can be moved about its axis S to the firing pin system 34 including firing pin 22 against the primer 20 the cartridge 21 to move.

However, if there is no proper locking, the locking slide remains 6 in its starting position, is the lever 31 then tipped so that the second lever 32 the hitting piece 33 assumed, this can not be moved.

Is the locking slide 6 For example, in an unwanted intermediate position, which also no proper locking is guaranteed, the hammer remains 33 through the lever 32 assumed.

In general, such active systems must be protected. Therefore, it is proposed in the kinematics 30 one, but preferably two fuses 35 . 40 which monitors a shot firing that approves a corresponding shot when properly locked and with the lock unlocked 4 prevented.

This is the firing pin system 34 through a first fuse 35 a lever 37 with recess 38 formed, secured, with the recess 38 the cross section of the firing pin system 34 corresponds, so in the locked state of the lever 37 the firing pin 22 with firing pin system 34 at a distance 36 to the primer 20 holds. firing pin 22 and striker system 34 are preferably made in one piece and also form a technical / constructive unit.

For example, to avoid that in an unsafe state, an accidental ignition of the cartridge 21 could be done is another (second) backup 40 involved. This further backup 40 is due to a placement of the firing pin system 34 as a parallel backup 40 for the first backup 35 through another lever 41 realized. This lever 41 works with the kinematics 30 together, what a moving means 42 involved is that the lever 41 with the kinematics 30 functionally connects.

Upon successful locking of the closure 4 is the moving medium 42 on the lever arm of the first (lower) lever 31 the kinematics 30 on. This guarantees a dip of the (upper) subordination 41 over the way 43 , As well as the safety lever 37 the firing pin system 34 has released, is the firing pin system 34 with firing pin 22 spring assisted on the way 36 for piercing the primer 20 emotional.

In case of a faulty locking, the movable means 42 not at all or not the full way 43 for the subordination 41 release the subordination 41 needed to hit the striker system 34 on the firing pin 22 to ensure that even with unintentional Freigebe the firing pin system 34 an ignition by the second fuse 40 is excluded.

It is understood that the two ways 36 and 43 are coordinated.

Only for the sake of completeness it should be mentioned that with another fixed, preferably Waffengehäuseseitig integrated backdrop 50 a check is provided, with which it can be checked whether the weapon barrel 3 is properly locked. If this is not the case, the entire shutter supply 1 / Locking system locked.
