Description

Closure guide device for a closure arrangement and

The invention relates to a closure guide device for a

Closure assembly of an automatic rapid-fire weapon and an automatic rapid-fire weapon with a closure guide device.

The directional indications used above, below, at the front, at the back, at the right and at the left refer to a weapon held in the attack from the point of view of a shooter.

Generally, various closure guide means for guiding a weapon lock are known. For example, DE 103 49 160 B3 of the same applicant shows a weapon component with a hollow body profile for receiving individual weapon elements. in the

Housing is arranged a slide rail with a cross-sectional profile, the

Engagement is designed in a corresponding groove in a closure element. The slide can be designed to guide the closure element as a roller rail.

From DE 43 45 591 B4 a self-loading grenade launcher of the same applicant is known in which the closure head a centrally arranged cam lever driver is formed. The cam follower may be formed as a roller rotatable about a vertical axis. This roller runs in a curved cam in the cam lever, which forms the control cam, and controls the Muntionszufuhr

(Belt promotion). A so-called pass-round rod fastened in a steel block passes through the housing and guides the ground-locking fastener as it moves along its longitudinal axis. US 3,563,132 shows a cam lever with a control rail which extends between two guide rollers on the closure head.

DE 1 678 508 B shows a gas pressure charger with a gas piston operated closure for a firearm. Lock carrier and lock head each comprise laterally oriented guide vanes which slide in corresponding grooves in the weapon housing. Further, a roller is arranged on the closure carrier, which enters the return mechanism of the closure in a cam groove on the belt switching mechanism and the gear switching mechanism via a sprocket on.

DE 197 26 032 A1 shows a closure system for a firearm MKM 88. A control lug and a lateral control cam are arranged on a closure carrier of the gas pressure charger. The cam prevents a twisting of a

Lock head control bolt, which is intended to reduce the brake friction of the bolt head. A locking lug guides the individual elements. In addition, in the

Weapon housing laterally arranged slide rails provided in which the

Locking piece is slidably mounted.

Finally, DE 38 35 556 AI shows a straight-pull system for

Firearms. For straight guidance of the closure two skids are provided. CH 51 131 A shows a straight-pull fastener with locking lugs, which have inclined locking surfaces.

Overall, known closure guide devices are usually complicated and cost-intensive to manufacture because of the necessary tight tolerances and may only provide limited functionality of the closure guide. For example, tilting of the closure guide device can occur, in particular in the case of rail guides, since there is often a large amount

Guide clearance is required to keep the guides insensitive to dirt. In the case of tightly guided guide or control bolts, on the other hand, high frictional forces can occur which increase the wear and / or the available actuating forces for

Reduce weapon functions (e.g., belt conveyance).

Against this background, it is an object of the present invention to provide an improved Verschlussfuhrungseinrichtung, which at least partially overcomes the above disadvantages. This object is achieved by the subject matters of the independent claims. Further advantageous embodiments and preferred embodiments are in the

Subclaims shown. According to claim 1, a closure guide assembly according to the invention comprises a carrier element arranged in the closure arrangement, a control element arranged on the carrier element and a guide element which guides the closure arrangement along a closure guide path, the carrier element having an axis of symmetry perpendicular to a axis of the axis on which the control element and the guide element are arranged coaxially.

Claim 13 relates to a rapid-fire weapon with a closure guide device.

A closure guide device according to the invention can also each comprise a plurality of control and guide elements, which are arranged on the carrier element.

Preferably, the closure guide device according to the invention each comprises a control and a guide element.

Control and guide elements are mounted on the carrier element coaxially to the axis of symmetry. The control and the guide element can the same

Have dimensions, or the control can be made larger or smaller than the guide element. Control and / or guide element can be arranged for example laterally from the closure assembly outstanding or at the top of the closure assembly.

The guide element is guided during a closing movement of corresponding guideways of a weapon housing. The guideways may be formed in the weapon housing and are configured to form a functional unit with the guide member. For example, in the housing

Rail-like guide profiles may be formed, on which the guide element is guided slidingly and / or rolling during a closing movement. About the coaxial arrangement of the control and the guide element can be on the control acting transverse forces on the guide element rolling and or sliding in the housing or the housing half shells initiate. Overall, a high

Efficiency of the closure effect achieved by low friction or sliding resistance. According to claim 2, the control and the guide element on the

Carrier element slidably mounted. A sliding bearing allows high dynamic peak loads with low frictional resistance. It can, for example

self-lubricating lubricious coatings are provided. Alternatively, other suitable bearings, such as rolling bearings or ball bearings can be provided here.

In accordance with claim 3, the control element is arranged and formed axially displaceably together with the carrier element in a receptacle surrounding the carrier element.

According to claim 4, the control element and the support element are mounted against the action of an actuating element (for example the spring pressure of a spring element) in the receptacle. Thus, the control can be moved together with the carrier element axially against the spring pressure and in the closure assembly, for example in the closure carrier, which then forms the receptacle, are added. In a corresponding embodiment of the spring element and dimensioning of the control and support member, the control can be completely submerged in the lock carrier. For example, if the control is formed on the top of the closure assembly, e.g. When closing a cartridge feeder cover, open the lateral edge of the guideway on the control lever on the control and push it into the lock carrier without damage.

In the embodiment according to claim 5, the support element passes through the

Guide element and is designed to be displaceable relative to the guide element. Thus, the control with the carrier element independent of

Guide element to be moved axially, whereby a simple component-saving design is possible. If the guide element is held in the guideway via the closure arrangement (claim 6), a secure guidance of the guidance element is ensured on the one hand and, on the other hand, the guiding stability of the closure movement

Closure assembly increases, extending over the guide element along the

Guideway supported on the housing.

Also, in the closure guide device according to the invention, the

Carrier be secured against the action of the actuating element via a securing element on the Verschlussfiihrungseinrichtung. As a securing element, a correspondingly suitable securing means, such as a pin, a bolt or a screw can be used. When mounting the closure guide device in the closure assembly, the spring element is first used, after which the one or more guide elements are used with the carrier element in a formed in the closure assembly recess. In this position, the

Guide elements are fixed (for example, by the support member), so that a

Falling out of the closure assembly is prevented.

Claim 7 relates to an embodiment in which the control and the

Guide element are each formed as a role in a movement of the

Unwind closure assembly on lateral guide and / or control surfaces. The carrier element forms the control and guide roller axis. An independent storage of the control and the guide element allow a comparatively small guide clearance between the guide roller and the guideways on the housing parts or housing sides. Thus, the control or the control roller friction higher actuating and control forces, e.g. transferred to the cam lever of Gurtförderung. The resulting counter forces are introduced via the guide element rolling into the housing. Overall, the shutter movement is characterized by low

Friction resistance of the control and the guide element further facilitated.

Upon movement of the closure assembly, the rollers may also rotate in opposite directions. (Claim 8) Since the rollers face each other Supported lying sides, they rotate in a closing movement and the operation of a cam lever in opposite directions. Advantageously, the stability of the closure guide can thus be increased. According to claim 9, at least one of the rollers on a spherical roller surface. A crowned cam roller, which serves as a control, can not tilt a guideway (eg cam lever). Overall, the coaxial design of the crowned cam roller and the guide roller allows a Verschlussfuhrung, in which

Guide element / guide roller or control / cam roller improved

support against each other and manufacturing tolerances can be increased. Crowned rolling surfaces improve the rolling properties at different axial angles of the rollers to the guide or control tracks.

According to claim 10, the control accesses the flow and return of the

Closure arrangement for controlling a cartridge feed on the control edge of a

Cam lever on. For this purpose, the control element can be arranged on the upper side of the closure carrier and the control curve can be arranged and formed in a cartridge feeder cover. The control controls so in a shutter movement - during a reload or a firing - a belt conveyor provided in the housing cover on, and transmits the mutually acting actuating forces on the guide element with little play on the weapon housing.

The control element moves along a control path defined by the guide element and controls the oscillating pivoting motion of the control element

Control lever, which in turn drives the delivery mechanism for cartridge feed.

The close tolerance of the guideways to each other reduces lateral accelerations of the weapon, which can affect their accuracy.

Overall, the invention provides a compact Verschlussfuhrungseinrichtung, with which the Gurtförderkraft increases, reduces the Bewewgungswiderstand the closure device and so the overall function of the weapon to be improved can ensure that the entire fire cycle is low-friction and low-lateral acceleration and so ultimately the reliability and accuracy are increased.

The invention will be described in more detail by way of example with reference to the drawings. In the figures, like reference numerals designate like elements throughout.

An embodiment of the present invention will be described below with reference to the drawings, in which shows

Functional sequences in the locking / unlocking;

FIG. 7 shows a representation of the closure head in a side view, FIG. 7a shows a detailed illustration of a locking lug of the closure head from FIG. 7 (detail Y); and

(A-A).

The embodiment shown in the figures shows a closure assembly of a machine gun, not shown, which is designed as a gas pressure loader. FIGS. 1 to 5 show the essential components.

The closure assembly comprises a closure support 1, which is coupled at its front end via a gas pressure linkage 2 with the (not shown) Gasabnahme the weapon. It builds in a known manner, the gas loss over a

Gas take-off cylinder (not shown) on the front end surface of the piston 4 to a gas pressure which transmits a force on the gas pressure rod 2 on the closure support and this in the housing 6 (see Figure 3) moves backwards.

The housing 6 (see FIG. 3) is here formed by two housing shells 8 and 10, which in their interior serving as a closure guideways guide rails 12, 14, 16 and 18, which guide the lock carrier 1 in its reciprocation in the housing 6 ,

The lower guide rails 12, 14 engage in the guide grooves 20 and 22 on the left and right sides of the closure support 1 and guide it horizontally in the longitudinal direction - transversely and vertically fixed -. along a soul axis 24

(see FIGS. 1 and 2) in the housing 6.

Since between the front and rear left guide 20 and right

Guide grooves 22 a guide-free gap 21 is formed, the guide is particularly low friction and insensitive to contamination. Dirt is from the guide grooves 20, 22, which surround the guide rails 12 and 14 claw-like, stripped and removed from the guide rails 12 and 14, so that the Dirt can not fix in the actual management area. In this way, the actual guide surfaces and thus the friction forces occurring are kept low. Characterized in that the guide grooves 20 and 22 are arranged in pairs at the front and rear ends of the closure carrier 1, this is supported over its entire length and guided without tilting in the housing.

In addition, the lock carrier 1 at the upper rear end of a

Closure guide device 30 which serves as a carrier element

Guide shaft 32 includes, which rotatably receives at its upper end serving as a control control roller 34 and one in a transverse recess 26 of the

Closing support 1 axially guided, serving as a guide element guide roller 36 passes through, which is also rotatably mounted on the guide shaft 32 and laterally beyond the side cheeks of the closure support 1 protrudes. Guide shaft 32, control roller 34 and guide roller 36 are arranged coaxially with respect to an axis of symmetry 33 which is perpendicular to the axis of the soul 24. The guide shaft 32 itself is seated axially displaceable in a receiving opening 38 of the closure carrier 1 and is pressed by a spring 40 upwards and is against the spring pressure down into the serving as a receptacle closure carrier 1 in displaceable. The axial travel is defined by a recess 42 on the outside of the guide shaft 32, in which a locking pin 44 passing through the locking carrier 1 in the transverse direction forms a stop. The guide shaft 32 is thus displaceable between the upper and lower stop surface of the recess 42 against the retaining pin 44, which also prevents the guide shaft 32 of the spring 40 upwardly from the Aufnahmeöffhung 38th

is postponed. The control roller 34 is via a rivet 46 and a

Washer 48 is rotatably fixed to the upper end of the guide shaft 32.

In the illustrated embodiment, the control roller 34 (control) engages in the U-shaped control link of a cam lever 50, the control roller 34 with its spherical Umfangsfiäche alternately engages the inner edges of the lateral legs 52 and 54. Thus, in the case of advancing and returning closure carrier 1, the

Control roller 34 as a drive cam which reciprocates the cam lever transversely to the axis of the soul 24, which in turn drives a cartridge conveying mechanism. Of the Cam lever 50 transmits depending on its direction of movement via its legs 52, 54 transverse forces on the control roller 34 and thus on the guide shaft 32 on the lock carrier 1, which is tilted transversely to the right or left to the housing 6. So that these transverse forces do not impair the guiding properties and the mobility of the closure carrier 1 along the axis of the soul 24, the likewise crowned guide roller 36 on the guide rails 16 and 18, respectively, transfers these transverse loads to the housing 6. Thus, the guide grooves 20 and 22 do not jam with the guide rails 12 and 14. The control and transport function of the control roller 34 thus causes only a very small, the movement of the

Lock carrier 1 in the housing 6 retarding friction effect.

The execution of these guiding or control elements as crowned rollers 34, 36 ensure a particularly smooth running. For example, if the right leg 52 causes a left-acting force on the right side of the control roller 34 via the control edge, the guide roller 36 on the left side engages with the

Leading edge of the left guide rail 16. i.e. the rollers 34 and 36 roll in opposite directions on opposite flanks. By a corresponding clearance or a dimensioning of the distance between the mutually facing flanks of the guide rails 16 and 18 and the legs 52 and 54 so that a particularly smooth guiding function can be realized. The crowned rolling surfaces of

Rollers 34, 36 ensure a clean unrolling function even with slightly tilted position of the closure support 1, and roll in slightly tilted position with their rolling surfaces on the guide flanks of the guide rails 16, 18 and the inner flanks of the legs 52, 54 of the cam lever 50th

The cam lever 50 is arranged in a swing-down hinged lid 56 which receives a belt conveyor mechanism (not shown). Since the guide shaft 32 is designed to be retractable with the control roller 34 via the spring 40 in the lock carrier 1, the cover 56 can be closed in any desired closed position without the risk that the cam lever 50 or the control roller 34 will be damaged. If one of the legs 52, 54 reaches the control roller 34 with its downwardly pointing end face, this is combined with the control roller 34 Guide shaft 32 is moved into the receiving opening 38 in the lock carrier 1 into it. In a through-loading movement of the closure carrier 1 along the axis of the soul 24 then slides the upper end face of the control roller 34 as long at the lower end face of the legs 52 or 54 along until the control roller 34 again completely enters the path of the cam lever 50 and there by action of the spring 40 occurs.

To improve the rolling properties of the control roller 34 and guide roller 36, the outer surface of the guide shaft 32 and / or the inner surfaces of the

Control roller 34 and the guide roller 36 have particularly lubricious surfaces (coating, processing). It is also possible for the control roller 34 and the

Guide roller 36 in turn via suitable roller bearings with the guide shaft 32 to connect. In other embodiments (not shown), roller bearings can also be provided in the region of the guide grooves 20 and 22 in order to further reduce the frictional resistances to the guide rails 12, 14, 16, 18 during the movement of the closure carrier 1 in the housing 6 in these regions. There are also embodiments in which instead of the rollers (control roller 34, guide roller 36) slidably to the

Guiding flanks or the inner flanks of the cam lever attacking control / guide elements are provided, which are also with respect to the guide shaft (32) movable / displaceable Such elements are then at least Klappsymetrisch to one of the core axis (24) and the axis of symmetry (33) spanned

Plane of symmetry.

The closure arrangement shown is provided with a so-called. A rotary cam closure in which a closure head 100 is axially displaceable and rotatably received between a locking and unlocking in a guide sleeve 58 at the top of the closure carrier 1. At the front end of the carries

Locking head 100 in two consecutive wreaths four front 104v and four rear 104h locking warts, each one (in dial orientation) in pairs one behind the other between one and two o'clock of the four and five o'clock, the seven and eight o'clock and the ten and eleven Clock position are arranged. Between

Locking lugs 104v, 104h are laterally longitudinally extending gaps provided, which serve for the locking function in a locking piece 200 and for guiding the closure head 100 in the housing 6.

The illustrated closure assembly is intended for a so-called gun to fire, in which the entire closure assembly is located behind the ammunition before firing and advances upon firing a shot, feeding the ammunition into the ammunition bearing (not shown) chambered there and after latching of the lock ignites. In Figures 1, 2, 4 and 5, the locking head 100 is shown in its unlocked position and in Figures 6d-f in its locked position. During the movement of the closure assembly in the housing 6, the closure head 100 against

unintentional rotation out of the unlocked position by the guide rails 16 and 18, which extend in the two lateral gaps (nine o'clock and three o'clock position) between the locking lugs 104v and 104h.

Furthermore, two feed tabs 108 are provided at the front end of the closure head 100 in 12 o'clock position, between which a Ausstoßerschlitz 110 extends. These Zuführnasen 108 serve the cartridge feed, while a fixedly arranged on the housing ejector (not shown) in the backward movement of the empty shot

Cartridge ejects from the gun (see below). The pairs exist

Feed tabs 108 allow stable guidance of the cartridge in ammunition transport in the weapon. The rotational movement of the closure head 100 is transmitted via a downwardly projecting control bolt 102 (see Figures 4, 5 and 7), which projects into the control link 60 of the closure carrier and there during the relative movement of the closure head 100 to the closure support 1, depending on the direction of movement and the operating state of the weapon is deflected in different rotational positions. For this purpose, the

Control link 60 a front linear guide portion 66 and a rear

Linear guide portion 68, which merge via a control edge 62 for locking and a control edge 64 for unlocking each other. At the rear end of the front Linear guide portion 66 is a transverse to the axis of the soul 24 arranged plane

Stop surface 70 is formed, the so with a rear end face 128 on

Control pin 102 cooperates, that in the leading lock carrier 1 and arranged in the linear guide portion 66 control pin 102, no angular momentum is transmitted to the closure head 100.

The control pin 102 is formed with a wedge-shaped radially outwardly widening cross-sectional profile and engages in the correspondingly formed

Receiving profile of the control link 60 and in particular the linear guide portions 66 and 68 a. Thus, the closure head 100 is held in the control link 60 as in a dovetail guide and secured against tilting in the guide sleeve 58. The closure head (e.g., with the closure assembly removed) can not be accidentally levered out of the guide sleeve 58, particularly if the rear end of the closure head is in the guide sleeve 58 only with slight overlap (see position in Figure 4).

For the scheduled removal of the closure head, a removal window 71 is provided at the rear end of the linear guide region 68, from which the control bolt 102 can be swiveled out by means of a rotational movement of the closure head 100 in the guide sleeve 58, so that then the closure head 100 forward from the guide sleeve 58th is removable.

In the closure head 100 extends coaxially to the axis of the soul 24, a firing pin channel 1 16, in which the firing pin 1 18 is slidably guided. The firing pin 1 18 is at its rear end with a ball head 120 in a receiving camp 59th

taken and there via a transverse pin 122 axially fixed in the lock carrier 1. During the relative movement between the closure carrier 1 and the closure head 100, the firing pin 1 18 moves together with the closure carrier 1, relative to the closure head 100 to the front and to the rear. During the firing, the firing pin 1 18 pushes through the firing pin opening 124 and exits the impact floor 126 at the front end of the bolt head 100, where the bottom of the cartridge to be fired abuts and strikes the firing plate. In the extraction of the cartridge engages an extractor claw 1 12, which is pressed via a spring-loaded pressure pin in its holding position. In this case, the clamping force is adjusted so that it can be swung radially in the cartridge feed over the rear edge of the cartridge bottom, and then to invade the Auszieherrille the cartridge fixed in the cartridge chamber.

The locking lugs 104 on the closure head 100 interact with the locking lugs 204 on the locking piece 200 during the locking process. First, the bumps 104 between the recesses 202 (FIG. 8) dip into the locking piece 200 and are brought into a position in which the

Control edge 62 engages to lock in the control link 60 on the control pin 102 and this twisted and thus the locking lugs 104 before the

Locking lugs 204 in the locking piece 200 brings (the locking head 100 is twisted), so that the rearwardly facing end faces 106 of

Locking lugs 104 on the forward facing end surfaces 206 of the

Apply locking lugs 204 and thus lock the locking head in the linear direction (in the direction of the core axis 24), ie lock it. This is the

Locking head 100 also accurately to the cartridge chamber (not shown) set, which is worked out at the rear end of the gun barrel (not shown), which in turn is fixed and connected in a defined position with the locking piece.

When unlocking the control edge 64 engages in the control link 60 in a relative movement of the closure carrier 1 to the closure head 100 on the control pin 102 and turn it out of its locking position, so that the closure head 100 again with the locking lugs 104hv through the recesses

202 on the locking piece 200 can be led out linearly to the rear.

To improve the locking and unlocking function in the locking piece 200, a guide channel 209 (see Fig. 6c) is provided, which partially on

Cams portion 208 (see Figures 6 and 8) along and with a

Control shutter cam 104h 'cooperates on the closure head 100. The guide channel 209 extends between the dot-dashed lines shown in Figure 6c. He is defined by the facing each other

Side surfaces 207a and 207b of the circumferentially adjacent

Locking lugs 204a and 204b, through the cam portion 208 at the control lug 204b and a guide surface 205 at the

Locking wart 204a. The thus defined guide channel 209 leads the

Control plug cam 104h 'on its side edges 109a and 109b via a control section 132 and a guide section 111 (see also Figures 6, 7 and 7a). The effect of this arrangement is mainly used to improve the cartridge extraction process and to make the entire movement during unlocking and locking liquid and low-stress.

The exact function becomes clear from a complete cycle of movement that the shutter assembly undergoes in delivering a shot. This is shown schematically in FIGS. 6a to 6k. Locking warts 104 and 104h ', 104v and

Locking warts 204 and 204a, b are unwound and shown twisted to each other. The corresponding position of the control pin 102 in the control link 60 is shown hatched.

Trigger the shutter

When the weapon is cocked, the closure assembly (lock carrier 1 and closure head 100) is in its rear position in the housing 6

Locking springs (not shown) are tensioned and engage in the region of the two closure spring eyes 72 on the closure support 1 and are on the closure spring guide rods (not shown), which

Pass closure eyelets 72, cocked. The closure carrier 1 is held by the trigger mechanism (not shown) on the detent lugs 74. The closure head 100 is in its unlocked position and is held on the guide rails 16 and 18 in this rotational position. The control pin 102 is located in the front linear guide portion 66. Upon release of the shutter assembly of the detent lug 74 is released, and the

Shutter assembly speeds forward under the action of the shutter springs (in the arrow direction, see Fig. 6a to 6e).

Cartridge feed (Fig. 6a)

The Zuführnasen 108 attack at the bottom of a aufgegurtete cartridge, unbegurten this and lead the cartridge in the further movement of the closure assembly forward through the locking piece 200 into the cartridge chamber of the gun barrel (not shown) in the

Locking piece 200 is fixed. At the latest when hitting the Zuführnasen 108 on the cartridge bottom of the closure head 100 is pushed in the lock carrier 1 to the rear. In this case, the control pin 102 moves relative to

Lock carrier 1 in the control link 60, in the front

Linear guide portion 66 to the rear and hits there to the level

Stop surface 70 at. The bumps 104 dive the recesses 202 between the locking lugs 204 passing into the locking piece 200, at the top there is a feed ramp 210 for the cartridge, via which it is further inserted into the chamber of the gun barrel. The Steuerverschlusswarze 104h 'is doing in the Guide channel 209 introduced, and axially guided over the side surfaces 207a, b at their side edges 109a, b in the guide channel 209.

Lock the lock (Fig. 6b-d)

The leading, 100 guided by the guide rails 16, 18 positively in the housing closure head 100 leaves with its front lobes 104v the guide rails 16, 18 and overflows with the front

Buttress row 104v, first the rear locking lug row 204 of the locking piece 200. During further forward flow of the closure head 100 and the rear locking lug series 104h of the closure head 100 runs from the guide rails 16, 18 from.

The closure head 100 remains in its unlocked position until the control shutter cam 104h 'abuts with its control section 132 against the cam section 208 in the locking piece 200, which transmits an angular momentum to the closure head 100, so that it is twisted with its locking lugs 104 - in the present case Case against the

Clockwise by about one-third of its total rotation. At this time, the control shutter cam 104h 'becomes at its control portion 132 and its

Guide section 11 1 on the guide surface 205 and the

Cam section 208 in the guide channel 209 between the

Locking warts 204a, b out.

By the one-sided impact of the control section 132 of

Control plug cam 104h 'on the cam portion 208 of

Steuerverriegelungs warze 204 b, the closure head 100 is biased on one side and has a tendency to escape transverse to the axis of the soul 24 and to

jam.

The outer diameter of the cylindrical shank surface 105 (FIGS. 1, 2 and 5) extending between the locking lugs 104 is set to the inside width w (inner diameter) between the radially inwardly facing head surfaces 203 of the locking lugs 204 tuned (see Fig. 8). In such a way that the closure head 100 can not escape and tilt during the locking process. Rather, it is supported with its cylindrical shaft surface 105 on the corresponding top surfaces 203 of the locking lugs 204. As a result, the closure head 100 is guided axially in the locking piece 200, does not tilt, converts its forward movement into a rotational movement without major friction losses, and locks smoothly in the locking piece 200.

In this case, the rear stop surface 128 of the control pin 102 from the area of the stop surface 70 in the control link 60. The control edge 62 for locking in the control link 60 engages a corresponding control surface of the control pin 102 and continues the locking function, by the relative movement between cam section 208 and control section 132 has been initiated. In this case, the control edge 62 sets for locking on a corresponding control surface of the control pin 102 and thereby twists the closure head 100 further into its locking position.

In this case, the cartridge bottom sets completely against the impact bottom 126 of the closure head 100, and the extractor claw 1 12 snaps into the

appropriate Auszieherrille on the cartridge bottom.

Upon further rotation of the closure head 100, the locking lugs 104 reach in front of the locking lugs 204, and the rear end surfaces 106 of the lobes 104 behind the front end faces 206 of

Locking warts 204 complete. In this case, the closure head 100 performs a rotation about another two thirds of its total rotation. The locking end surfaces 106 and 206 are inclined at a self-locking angle to the axis of the soul 24, and the remaining locking takes place in a kind of screwing movement with a flat pitch between the locking lugs 104 and the locking lugs 204. The surface coupling is self-locking. That is, an axial effect on the closure head does not lead in that the bumps 104 move independently from their Verrieglungslage.

The locking process described above proceeds extremely smoothly and without strong rebound movements by the pilot control (cam section 208 and control section 132, about one third of the total rotational movement) and the final final locking. The inclination of the end surfaces 106 and 206 facilitates this process and reduces the internal frictional resistance. The inclination of the cam portion 208 corresponds to the inclination of the control portion 132, and the inclination of the guide surface 205 and the guide portion 11 1 and is adjusted to the inclination of the control edge 62 for locking or the control surface on the control pin 102 so that both processes smoothly merge into each other , Of the

Inclination angle of the control edge 62 for locking the closure head is selected with respect to the inclination angle of the cam portion 208 so that the rotational acceleration of the locking closure head is increased in the transition of the closure head control from

Cam section 208 on the lock control edge 62nd

The inclination angle of the control edge 62 corresponds to the inclination angle of the control edge 64 for unlocking, to ensure that the

Control bolt 102 with as little side play over the entire length of the control link 60 and above all by the control edge regions 62 and 64 can move.

Firing / Firing the Cartridge (Fig. 6d)

The control pin 102 is now at the front end of the rear linear guide region 68, and the closure head 100 itself is fixed in the linear direction in the locking piece 200 and locked in the circumferential direction. The closure carrier 1 now moves further relative to the closure head the front and pushes the firing pin 1 18 in the firing pin channel 1 16 to the front and so far that the tip of the firing pin 1 18 pushes forward through the firing pin opening 124 and ignites the cartridge. In this case, the control pin 102 moves in the linear guide region 68 relative to the further forward sliding closure carrier 1 to the rear until the closure carrier 1 with its front 61 on the rearwardly facing end face 201 of

Locking piece hits and its forward movement stops. As a result, the relative movement between the closure carrier 1 and the locking piece 200 is interrupted.

After firing, the closure carrier 1 is pressed back against the action of the closing springs via the gas pressure acting on the piston 4 and initially moves back relative to the closure head 100 (in the direction of the arrow, see FIGS. 6f to 6k). The firing pin 1 18 is pulled over the ball head 120 back into the firing pin channel 1 16. In this case, the control pin 102 moves forward in the linear guide region 68 and comes into engagement with the control edge 64 for unlocking. (Fig. 6f)

Unlocking and removing the cartridge (Fig. 6f-6h)

Due to the now beginning unlocking the

Locking lugs 104 are rotated out of the area of the locking lugs 204 (FIG. 6g). In this case, the contact pressure between the impact floor 126 and cartridge case bottom relaxes, and the extractor claw 112 can rotate in the Auszieherrille the cartridge case. The rotational movement is first applied between the control edge 64 and the control pin 102. By firing the cartridge case can be widened (gelidert) and very firmly wedged in the chamber of the barrel. In this case, in the unlocking rotation, the control section 132 is supported on the

Cams portion 208 and pulls over a screw with increased force and reduced axial velocity, the cartridge case from the (shown in Fig. 6g shown in Fig. 6h position) cartridge chamber. In this case, the control shutter cam 104h '- similar to the locking - at its control portion 132 and at its guide portion 11 1 on the

Cam portion 208 on the locking lug 204b and the

Guide surface 205 of the locking lug 204a guided in the guide channel 209.

After completion of the rotation of the locking lugs 104 are aligned with the recesses 202 in the locking piece 200. The control pin 102 abuts against the front end of the linear guide portion 66 and is now linear - with entrainment of the closure head 100 and the loosened, held by the extractor claw 112 cartridge case - from continue

moving back closure carrier 1 to the rear (Fig. 6i). In this case, lock head 100 and cartridge case reach out of the cartridge chamber and the locking piece 200 (FIG. 6k).

During the further return movement, the closure head 100 returns to the area of the guide rails 16 and 18, and the ejector projecting into the ejector slot 110 strikes the cartridge case down through the window 3 in the gas pressure linkage 2 and further out of the weapon. Upon further return, the closure carrier 1 abuts with a stop pin 76 on the bottom plate (not shown) of the weapon, which in the lower region of the closure carrier 1 in

Extension of the gas pressure linkage 2 is arranged.

In the interior of the closure carrier 1, this stop pin 76 is cushioned by a mechanical buffer 78, which realizes a high mechanical energy intake via an annular spring arrangement 80 and swallows a high proportion of the kinetic energy of the closure arrangement with low recoil. When you release the trigger, the closure assembly is again on the

Locking lugs 74 locked; after the last cartridge has been removed from the belt, the closure remains in its locked position. Further features and variants of the present invention will be apparent to those skilled in the art from the following claims.
