Definitions
- the invention relates to a breech block for a firearm, the breech block comprising at least one breech block head with a control bolt and a slide piece with a mounting groove and control link, and the bolt head and the slide piece being slidably inserted and detachably connected to one another, according to the preamble of claim 1.
- Firearms with a rotating head lock have long been known. Examples include the types M4 / M16 / AR15 and their derivatives.
- the breechblock comprises a slider arranged movably in the housing, or also called a breechblock carrier, as well as a breechblock head which can be rotated and displaced about the barrel axis in the slider along the barrel axis.
- the locking head is usually rotated by the interaction of a control bolt (or control cam, sometimes also referred to as a sliding block), which is arranged on the locking head, with a control link, which is arranged in the slider.
- the control link also called control cam
- the control link is often designed as a closed, elongated, essentially S-shaped groove with a helical or helical section.
- the helical section causes the rotational movement of the locking head by interacting with the control bolt when the locking head moves relative to the slider.
- control bolt As a separate component. It is inserted in a transverse bore in the bolt head and held there in position, for example, by the firing pin located in the firing pin bore. During assembly, the bolt head is pushed into the slide, then the control bolt is inserted into the bolt head through the closed control link located inside the slide. The control pin is often secured against falling out by the firing pin. Since the control bolt needs a corresponding material strength to absorb the forces during the locking process, only smaller wall thicknesses of the locking head remain in the area of the Cross hole for the control pin. This results in a relative weakening of the locking head and breaks repeatedly occur at this point in known locking heads of this type.
- the control bolt can be attached integrally to the bolt head.
- a locking head with an integral control bolt can be inserted into a split slide so that the control bolt is brought into the closed control link during assembly. It is then necessary to secure the locking head in the slider with clasps, slides or similar elements. Because of the complex geometries required, the manufacture of such split sliders requires a very high level of manufacturing effort. In addition, due to the large number of components, the assembly of such a locking head in the slider is more user-friendly.
- EP 0423678 A2 describes a lock with a control link that is open to the front and that extends in the circumferential direction to the rear; the locking head is secured in the slider or the control bolt in the control link via a separate, small-scale component that is secured by means of a pin. Assembly and disassembly are only possible using tools.
- EP 1718914 A2 describes a lock carrier with a control link that is open to the front and extends to the rear, with a push rod acting, among other things, on the control bolt.
- the closure described also has a fixed ejector, which causes a lateral slot in the slide. This slotted design of the slider has an unfavorable effect on the mechanical stability, which in turn increases the risk of breakage.
- the closure is constructed as simply as possible, that is to say with preferably as few components as possible, and that it can be dismantled without tools.
- Another task is to create a non-disintegrable coupling of the locking head with the slider in the installed state.
- the closure comprises at least one locking head with a control bolt and a slider, the slider having an end face and a mounting groove and a substantially S-shaped control link with locked position and entrainment position, wherein the mounting groove adjoins the locked position of the control link and is essentially U-shaped.
- S-shaped control links are known from the prior art.
- the control bolt When the lock is unlocked, the control bolt is located in an unlocking section of the control link that is closed towards the front, in the driving position.
- the control bolt When the lock is completely locked, the control bolt is in the locked position in the rear so-called locking section of the control link.
- the locking section and the unlocking section are connected to one another by a helical, or spiral-shaped, central section.
- the essentially U-shaped assembly groove begins on the end face of the slide in the running direction towards the rear and ends at the rear end of the control link and adjoins it.
- a mounting groove that merges into the control link in this way has the advantage that the locking head together with the control bolt can be inserted into the slide piece along the mounting groove. So it's easy possible to move the control bolt into the control link so that the bolt head is ready for operation.
- the bolt head and control bolt can be assembled before they are inserted into the slider. With the aid of an assembly groove and control link formed in this way, it is also possible for the control bolt to be formed integrally on the locking head.
- a high material thickness of the slider remains, for example on the front side for the, preferably symmetrical, interaction with a gas linkage, or also in the lateral and vertical direction, which promotes the stability of the slider.
- the number of components can be reduced compared to known sliding pieces. At the same time, tool-free disassembly / assembly of the locking head is promoted.
- the assembly groove has a first section, which extends backwards starting at the end face, and a second section adjoining the first section, which extends in the circumferential direction and a third section adjoining the second section which extends to vome.
- the U-shaped assembly groove with a first rearwardly extending section allows easy and simple insertion of a locking head with control bolt, the control bolt being guided in the first section of the assembly groove.
- the locking head is rotated in the direction of the third section, with the control bolt being guided in the second section.
- the third section is reached, the bolt head is moved forward again in the direction of travel and the control bolt is guided in the third section.
- the first, second and / or third section can be straight or also helical or spiral-shaped. It has proven to be particularly advantageous, in particular, to design the second and / or third section in a spiral shape. For the user, it is relatively easy - even without a direct line of sight - to see in which section the control bolt is located.
- the locking head cannot be secured in the slide, for example by means of additional components.
- the third section of the assembly groove can be viewed in the running direction and can extend to the rear adjacent to the locked position of the control link. It has proven to be advantageous that the third section extends 0.1 to 3 times the diameter of the control bolt to the rear, preferably 0.5 to 1.5 times the diameter of the control bolt. This measure has the advantage that the locking head has to be moved backwards at least partially from the locked position of the control link in order to bring the control bolt into the assembly groove and subsequently to be able to remove the locking head from the slider.
- unintentional twisting of the locking head into the second section of the mounting groove directly from the locked position is not possible. Additional components to prevent unintentional twisting can thus be omitted.
- a special embodiment is advantageous in which the first section is oriented parallel to the axis of the barrel core, since this particularly facilitates production.
- the second section is advantageous to design as a circular arc segment viewed from above, which, viewed from above, is oriented normally to the barrel axis, since the relatively simple manufacture and good visibility of the position of the control bolt during insertion is also given.
- a mounting groove designed in this way can essentially be viewed as U-shaped and is particularly easy to manufacture, e.g. by means of drilling and / or milling.
- the above-mentioned possibilities of forming individual or all of the three sections in a spiral shape can mean that additive manufacturing processes have to be used.
- the straight backward running assembly groove allows maximum space utilization in the slide while maintaining the integrity of the slide.
- the control pin can have a correspondingly large length, which is advantageous when interacting with the control link.
- the aforementioned designs are also advantageous with regard to simple assembly.
- the three sections are each formed approximately at right angles to each other, the description of the following situation also being analogous to any spiral sections:
- the locking head is guided straight back with the control bolt in the first section until the control bolt strikes the end of the first section .
- This position which is easy to determine, is followed by a rotation of the locking head with the control bolt in the second section of the control link as far as the stop at the end of the second section. Now the locking head is brought forward into the third section and then into the control link.
- the assembly groove and the control link have the same width at the locked position.
- the transition from the mounting groove to the control link is thus stepless and allows the control bolt to be introduced particularly easily from the mounting groove into the control link.
- This design is also particularly advantageous in production, since the assembly groove and the control link can be machined, e.g. milled, in one go at the locking position. This reduces work steps and costs in production.
- Another special embodiment can be designed in such a way that the control pin axis of the control pin is arranged in the assembly position in the first section of the assembly groove at an angle a to the weapon center plane, the angle a being 20 ° to 65 °, preferably 35 ° to 45 ° and the control pin axis of the control pin in the driving position at the front, closed end of the control link at an angle g on which the control pin axis of the control pin is in the assembly position, the angle g being 50 ° to 120 °, preferably 80 ° to 100 °.
- This arrangement of the mounting position and the driving position allows a sliding piece with very high integrity, in particular at the end face there is sufficient space for the interaction with a push rod, which is also centered around the locking head can be arranged.
- a purely “internal” assembly groove can thus be formed on the slide, which has a positive effect on the mechanical load-bearing capacity of the slide.
- the internal assembly groove allows a defined, necessary rotary movement to guide the locking head into the control link.
- the slide has at least one guide groove on the side, which is designed to guide the slide along a guide rail in a housing, preferably an upper housing part, the guide groove intersecting the control link and exposing it upwards.
- This arrangement of the guide groove in the slider is particularly advantageous since the slider can be guided precisely along the guide rail in the housing. Furthermore, this configuration allows a control window formed in the guide rail to release the rotary movement of the locking head, in addition to guiding in the control link, only when the control bolt can reach “through” the guide rail when the locking head is rotated through the control window.
- the arrangement of the control window is designed in such a way that precisely this rotational movement for locking the breech can only take place when the breech is in the locking sleeve of the firearm. If the lock with the slider is in a different, unlocked state, the interaction of the guide rail and control pin prevents the lock head from rotating.
- control bolt is designed as an incline at its outer end - viewed in the radial direction to the barrel axis - which in the driving position is parallel to the guide rail and is arranged flush with the guide groove.
- the control bolt can - at least on one side - achieve a maximum length, which is due to the Leverage has an advantageous effect when moving in the control link.
- the contact surface sliding surface
- the surface of the control bolt which is designed as an incline, when it interacts with the guide rail, and a low overall height of the sliding piece is promoted.
- control bolt is attached integrally to the locking head and preferably has a concave recess in the transition area between the locking head and the control bolt.
- An integral control bolt has a positive effect on the mechanical load-bearing capacity of the bolt head and the number of components required for a firearm can be reduced.
- a preferably circumferential clearance can be provided in the transition area of the control bolt to the locking head body. This clearance can be concave, preferably lenticular. Such a transition area from the locking head to the control bolt can reduce the notch effect in the transition area and the risk of the control bolt breaking is prevented.
- a firing pin is arranged in a firing pin bore in the bolt head in such a way that a firing pin spring arranged around the firing pin is supported on the bolt head and preloads the firing pin.
- the firing pin is supported by the spring preload on the slider in such a way that the control pin on the bolt head can only be moved from the control link into the mounting groove against the spring force of the firing pin spring.
- the invention is suitable for firearms in general, and therefore also for pistols, but is explained below using a carbine.
- Other components of the firearm such as the Fauf, cartridge chamber, locking sleeve with locking wreath, firing pin and firing pin spring, magazine or shaft are not explained in more detail here, since it does not affect the essence of the invention and the person skilled in the art Knowledge of the invention, if necessary or desired at all, can easily make modifications and adaptations based on his specialist knowledge.
- FIG. 1 shows a simplified side view of a firearm
- FIG. 2 shows a simplified exploded view of a slide according to the invention with a locking head from obliquely vome
- FIGS. 3a and b show a partially cut-out housing with slider and locking head in the unlocked and locked state as a 3-D view
- FIGS. 4a and b show the cross-sections, corresponding to FIGS. 3a and b, of a housing with slider and locking head along the control bolt axis in the unlocked and locked state
- FIGS. 6a and b show a top view of the slider from the front and a corresponding longitudinal section
- Control link and mounting groove in different positions and Figs. 8a and b a side plan view and a longitudinal section of the slider with bolt head and firing pin.
- left, right, up, down, front and rear always refer to the firearm from the point of view of the firearm when it is held ready to fire.
- the weapon has, going through the axis of the fan and oriented vertically, a weapon center plane, designated below as 90, which cum grano salis, forms a plane of symmetry.
- the upward direction is indicated by arrow 91, the normal direction upward by arrow 93 and the transverse direction to the left by arrow 92.
- the terms “front”, “rear”, “top”, “bottom” and so on are used in their usual form and with reference to the object in its usual position of use. This means that the muzzle of the barrel is “in front” of the weapon, that the bolt or slide is moved “backwards” by the explosion gases, etc .. Transverse to a direction essentially means a direction rotated by 90 °.
- the breech of a firearm comprises a slide piece and bolt head and firing pin and requires a locking collar of a locking sleeve, which is usually connected to the barrel.
- a lock for the sake of simplicity and better readability, the combination of sliding piece with bolt head (possibly with firing pin and firing pin spring) will also be referred to as a lock.
- the parts of the breech such as bolt head and slide are functionally connected to one another and form a unit, but the breech is not necessarily built into the firearm. If the breech is built into the firearm and functionally connected to it, this is referred to below as the built-in state or when the breech is built-in.
- the firearm is then typically in an operational state. If the bolt is locked (in the locked state or when the bolt is locked), the bolt head interacts with the locking ring and locks the cartridge chamber to the rear during the barrel, so that the weapon is ready to fire. If the lock is unlocked (in the unlocked state) the lock head no longer interacts with the locking ring and is in an (end) position.
- FIG. 1 shows a firearm schematically and has a barrel 1 with barrel core axis 11 and muzzle 14, a housing 2 with upper housing part 21 and lower housing part 22, a fore-end 81, a trigger 82, a magazine 83, a handle 84 and a stock 85 on.
- FIG. 2 shows an exploded view of a slide 4 according to the invention with a locking head 3, subsequently and for the sake of simplicity and better readability also known as a closure.
- the elongated locking head 3 has a firing pin bore 35 running in the axial direction and locking lugs 31 formed radially outward at the front end.
- the control bolt 33 which is preferably embodied as an integral part, projects radially outward, and the transition region of the locking head 3 to the control bolt 33 is embodied as a concave recess 331, preferably lens-shaped.
- the slider 4 comprises a longitudinal bore, referred to as a locking head receptacle 42, which is used to receive the locking head 3. At least one end face 49 is formed at the front end, which can interact with a push rod of a gas extraction system in order to bring the breech back after a shot has been fired during the automatic reloading process.
- the slider 4 further comprises, at least on one side, a lateral guide groove 45 which interacts with a guide rail 25 of a housing 2 and guides the closure in the housing 2 in the axial direction (see FIGS. 5a and b).
- a rearwardly extending assembly groove 46 is formed along the locking head receptacle 42, which, when the locking head 3 is inserted into the locking head receptacle 42, receives the control bolt 33 and guides the locking head 3.
- the assembly groove 46 merges into a control link 43; details on this are explained in a further sequence and in particular in FIGS. 6 and 7.
- the slider 4 is shown in plan view from the front.
- the end face 49 and the guide groove 45 (preferably formed on both sides) are clearly visible.
- the locking head receptacle 42 and the assembly groove 46 are located on the inside.
- a longitudinal section of the slider 4 along the sectional plane III is shown clearly in FIG. 3b, the assembly groove 46, which merges into the control link 43 (see also FIG. 4b).
- the sliding piece 4 has a high structural integrity and stability, the locking head 3 located in the sliding piece 4 is partially enclosed on its central part in the longitudinal direction and completely in the circumferential direction and the forces coming from the push rod can be transmitted over a large area at the end face 49 .
- 4a shows the position of the locking head 3 in the slide 4 when the lock is locked.
- the locking head 3 lies in the slider 4 in such a way that the control pin 33 lies in the control link 43 or partially protrudes through it.
- the locking sleeve 15 with the locking rim 16 of a barrel group is indicated by dashed lines. In the installed and locked state, this position of the locking head 3 in the slide 4 is the rearmost possible position, since the locking ring 16 blocks any further movement of the locking head 3 to the rear.
- FIG. 4b in which the U-shaped mounting groove 46 and the S-shaped control link 43 are shown schematically.
- This representation is a flat representation of the projecting person (development) through the control pin 33 in the respective position along the mounting groove 46 or control link 43.
- the U-shaped mounting groove 46 is viewed in the direction of travel 91 merges into the control link 43 from behind.
- the mounting groove 46 has an end that is open to the front and extends from this open end in a first section, preferably at least partially parallel to the barrel axis 11, to the rear. Adjacent to the first section follows a second section which is rotated in the circumferential direction, preferably essentially perpendicular to the first section. Adjacent to this is a third section which extends forward, preferably formed at least partially parallel to the barrel axis 11.
- the shape of the mounting groove 46 essentially corresponds to a “U” with a shorter leg (or also a “J”).
- Fig. 4b it can be seen that at the transition line 47, the mounting groove 46 merges into the control link 43, which extends further forward and, according to the prior art, is essentially S-shaped with a helical middle section, comprising locking cam 65 and unlocking cam 63, is trained.
- the locking curve 65 and the unlocking curve 63 can be formed parallel to one another or else be formed at different angles on the barrel core axis 11.
- the normal distance between the locking cam 65 and the unlocking cam 63 can correspond to the diameter of the control bolt or, in certain cases, a multiple thereof.
- the front end of the control link 43 is formed essentially parallel to the barrel core axis 11 and is closed towards the front and is arranged behind the open end of the mounting groove 46. In this way, the slider 4 has a relatively high material thickness at its end 49 in this area.
- the rear end of the control link 43, which adjoins the assembly groove 46, is designed essentially parallel to the barrel axis 11.
- the width of the mounting groove 46 and that of the control link 43 are preferably the same and essentially correspond to the diameter of the control bolt 33.
- the third section of the mounting groove 46 extends further back than the control link 43, namely 0.1 to 3 times the diameter of the control pin 33, preferably 0.5 to 1.5 times .
- the assembly position 61 shows the position of the control bolt 33 adjacent to the open end of the assembly groove 43, so to speak the first position of the control bolt 33 in the assembly groove 46 when assembling the lock.
- the locked position 62 shows the position of the control bolt 33 in the locking area of the control link 43 when the lock is locked.
- the locked position is directly adjacent to the fictitious transition line 47 shown in dashed lines and is the rearmost possible position of the control pin in the control link 43 (see FIG. 4a).
- the entrainment position 64 shows the position of the control bolt 33 in the unlocking area of the control link 43 when the lock is unlocked.
- the driving position 64 is directly adjacent to the closed front end of the control link 43 and is the foremost possible position of the control pin in the control link.
- the dismantling position 66 shows the position of the control bolt 33 in a rearmost possible position in the mounting groove 46.
- the distance between a locked position 62 and a dismantling position 66 corresponds to the shape of the third section in the range from 0.1 to 3 times the diameter of the control pin 33, preferably 0.5 to 1.5 times.
- This shape means that unintentional turning of the locking head out of the locked position (as would be possible with an L-shaped assembly groove) is prevented, since a movement must first be made to the rear in order to reach the dismantling position.
- the U-shape according to the invention thus provides protection against disintegration without the need for an additional component.
- the lock head 3 (with firing pin 50 and, if necessary, firing pin spring 51 - compare Figs. 2, 3b and 4b) is inserted with its rear end from the slide 4 into the lock head receptacle 42, so that the control pin 33 is in the assembly groove 46 is guided to the rear.
- the locking head 3 is rotated in the circumferential direction, so that the control bolt 33 is guided in the second section of the mounting groove 46.
- the locking head 3 and with it the control bolt 33 are moved forward and thus into the third section and further into the control link 43. The closure is thus in the assembled state.
- Figs. 5a and b show the slide 4 with the locking head 3 from FIG. 2 in an upper housing part 21 of a housing 2 of a firearm.
- the upper housing is partially cut out, which enables a clear view of the interaction of the control bolt 33 with the guide rail 25 of the upper housing part 21.

- Fig. 6a and b shows the lock in the locked state
- Fig. 6a and b shows the lock in the locked state
- FIGS. 7a and b show, corresponding to FIGS. 5a and b, representations of a slide with a locking head without a housing with the lock unlocked (FIG. 7a) and locked (FIG. 7b).
- the slider is arranged in the housing in such a way that the guide rail 25 of the upper housing part 21 engages in the guide groove 45 and the slider 4 can be moved back and forth in the housing.
- a guide rail 25 is formed on both sides of the housing, which has sliding piece 4 correspondingly also each have a corresponding lateral guide groove 45.
- a control window 255 is also formed on a guide rail 25 facing the control link 43.
- the first section of the mounting groove 46 lies on one side of the weapon center plane 90, the control link 43 on the other side.
- the control pin 33 is essentially cylindrical with a jacket surface 333 and extends outward in the radial direction of the locking head 3, along the control pin axis 334.
- the control bolt 33 is guided on its lateral surface 333 in the mounting groove 46 and the control link 43.
- the outer end of the control pin 33 is designed as a bevel 332 which is at an acute angle to the control pin axis 334.
- the bevel 332 can interact with the guide rail 25 of the housing and, when the lock is unlocked, as can be seen in FIG. 6a, preferably ends flush with the guide groove 45. Rotation of the lock head 33 when the lock is unlocked is prevented by the interaction of the control pin 33 (or its bevel 332) with the guide rail 25 in this position.
- the guide rail 25 has a control window 255 at the position of the control link 43.
- the control pin 33 can reach through this control window 255, that is, during the locking process, the control pin 33 is guided along the helical central section of the control link 43 and rotated in the circumferential direction, which is made possible by the control window 255.
- the control pin 33 extends along its control pin axis 334 to the outside.
- the control bolt axis 334a is at an angle ⁇ 36 on the weapon center plane 90.
- the control pin axis 334b is at an angle ⁇ 37 to the control pin axis 334a in the assembly position 61.
- the control pin axis 334c is at an angle g 38 to the control pin axis 334a in the assembly position 61.
- the angle a 36 can be 20 ° to 65 °, preferably 35 ° to 45 °.
- the angle ß 37 can be 35 ° to 90 °, preferably 55 to 65 °.
- the angle g 38 can be 50 ° to 120 °, preferably 80 ° to 100 °.
- the mounting position 61 (and thus angle a 36) is on one side of the weapon center plane 90, the locked position 62 and driving position 64 are usually on the other side of the side of the weapon center plane 90.
- the arrangement of the control pin axis 334a, 334b and 334c with the corresponding angles ⁇ , ⁇ and g enables a mechanically stable slider with high integrity with as much space as possible on the end face 49 for interaction with the push rod (preferably arranged centrally around the locking head) of a gas system.
- the firing pin 50 lies, preferably centrally, in a firing pin spring 51 in the firing pin receptacle 35.
- the rear end of the firing pin protrudes from the slider 4 for cooperation with a striking device, not shown.
- a collar on the rear section of the firing pin 50 the latter is supported on the inside on the slide 4, so it cannot fall out to the rear.
- the firing pin spring can be supported on the firing pin 50 and bolt head 3. Since the firing pin 50 is supported to the rear in the slide 4, the firing pin spring 51 pushes the bolt head 3 forwards. In the assembled state, the bolt head 3 is thus pushed forward by the spring preload of the firing pin spring 51 in the slide 4, the The control pin 33 is correspondingly in contact with the front, closed end of the control link 43 and is in the driving position 62.
- the lock head 3 in the slider 4 can be pushed backwards against the spring force, with the control bolt 33 into the dismantling position 66 of the assembly groove 46, and after turning so that the control bolt 33 lies in the first section of the assembly groove 46, it can be pushed forward can be taken from the slider 4.
- the lock according to the invention can be made very robust in the assembled state and can be dismantled without tools if necessary; the lock is secured against disintegration in the installed state only by means of guide rail 25 and without further components.
- the “essentially S-shaped control link 43” has two end sections which essentially run in the direction of the fan axis 91.
- the “essentially U-shaped or J-shaped” assembly groove 46 has two legs which run essentially in the direction of the fan axis 91.
- “essentially” means an alignment that preferably means parallel to the fan axis 91, but includes a deviation of up to 30 °, better just 15 ° for each of the legs or the end sections, each independently of one another.
- U-shaped or J-shaped does not necessarily mean the end with an arch, a rectangular design, as shown, is also possible.
- the two legs or end sections do not have to be parallel to one another.
- the invention is not limited to the illustrated and described exemplary embodiments, but can be modified and configured in various ways.
- the shown cross-sectional shapes of the mentioned housing and locking parts, bolts, rails, recesses, etc. can be adapted to the given basic data, even the catches and the questions with regard to the housing can be easily adapted for the person skilled in the art with knowledge of the invention.
- equivalent embodiments are obvious with knowledge of the invention and can be carried out without further ado by a person skilled in the art.
- an “essentially L-shaped cross section” comprises two elongated surfaces, which merge at one end into the end of the other surface, and whose longitudinal extension is arranged at an angle of 45 ° to 120 ° to one another.
