Definitions
- the invention relates to a lock system for a firearm according to the preamble of claim 1.
- the lock system for a firearm should be understood to mean the arrangement of functional components that are used to trigger the shot, including the components that are used to secure the system and, in particular, to temporarily define the components used to trigger the shot.
- Firearms have different lock systems depending on their design.
- break-open rifles there are lightning locks, box locks and sidelocks.
- the lock By tilting the barrels of a single shot rifle, for example a shotgun, a single shot rifle, a double rifle or a triplet, the lock is cocked, that is, a hammer is moved against the spring pressure of a mainspring into a non-triggered spring loaded position and there with a Detent set.
- this locking position can be released so that the striker hits a striker under the pressure of a striker spring, which emerges from a striker opening and pushes in the primer of a cartridge and thereby ignites.
- the firing pin With rotating chamber locks of bolt-action rifles, the firing pin itself is in principle brought into operative connection with the mainspring or is in operative connection with this, whereby when opening (in rare cases also closing) the breech and thus the locking of the chamber in the barrel or in a sleeve head the Striker spring is tensioned.
- a firing pin nut at an axially opposite the cartridge chamber opposite the end of the chamber, which is moved backwards when the breech is opened or closed, thus tensioning the mainspring.
- the firing pin nut When the chamber lock is pushed into the sleeve in which the rotary chamber lock is axially displaceable, the firing pin nut is axially blocked by a detent so that the clamping tion of the mainspring is retained.
- the catch By operating the trigger, the catch is usually lowered down, so that the firing pin is suddenly moved forward under the spring pressure of the Schlagfe, emerges from the bottom of the chamber and ignites the cartridge.
- rotary head locks With rotary head locks, as they are usually found on semi-automatic, partly also on fully automatic firearms, a striker is pressed into a detent position by running back the closure and held there by a detent against the pressure of a mainspring. If the lock snaps back into the locked state again, in particular through the action of a lock spring, and locks with the barrel or a case head, the striker can also pivot forward in the direction of the striker by releasing the latching connection by actuating a trigger and strike the striker, with
- the Schlagbol zen is resiliently mounted within the rotary head lock and by striking the striking piece at the back, it also shoots out of the shock base and ignites a cartridge via the primer.
- the lock can thus be an integral part of the breech, as in the case of rotary chamber locks for bolt-action rifles (in which the firing pin nut is sometimes also referred to as a lock), but can also be functionally separated from the actual breech, as in drop barrel rifles.
- a lock is to be understood as the functional unit that interacts to trigger the shot and also includes a safety device.
- the structure is determined by the functions.
- Such firearms have a barrel to give the projectile the direction and also to provide for the development of the gas pressure, thereupon a breech that closes the barrel tightly to the rear at the moment the shot is fired and holds the cartridge in place, a magazine or another Cartridge feed area, from which the slide, when moving towards the barrel in order to close it, pushes a cartridge out and pushes it into the chamber of the barrel before it pushes the chamber backwards.
- the lock which includes the hammer, usually a trigger rod or a comparable component and the trigger.
- the detent and the counter-detent are formed, which cooperate restrainedly in the cocked state of the hammer and thus of the lock, the hammer.
- the striker spring is present, which holds the striker under pretension in the cocked state in order to enable a very rapid movement towards the firing pin.
- a shoulder piece is usually attached in order to be able to pull the weapon into the shoulder when the shot is fired, on the one hand to enable precise target acquisition and on the other hand to intercept the recoil.
- firing pin safety is considered to be safest because it secures the last functional component in front of the cartridge's primer against displacement, even if the lock is accidentally triggered.
- rod safety device which secures the trigger rod so that if the trigger is accidentally triggered, the trigger rod is not moved and thus the latch of the trigger rod and the counter-latch of the hammer or the bolt nut do not disengage.
- Even the rod safety is less secure than the firing pin safety, since it cannot be ruled out that the locking connection is released and the striker hits the firing pin and triggers a shot due to external influences, such as falling or falling.
- a third known safety device is the trigger safety, in which only the trigger blade is secured against movement so that accidental pressure on the trigger blade does not move the trigger bar.
- This security has an even lower security potential compared to the two aforementioned security devices, since the mechanical chain of the trigger rod and striker or firing pin nut is not secured and can also be loosened by impact or impact.
- so-called hand tensioning systems were developed, in particular by the company Blaser, in which the mainspring is tensioned before the shot is fired, while the locking connection between the striking piece and the trigger bar or the firing pin nut and the trigger bar already exists, the whole However, the system does not trigger even when the trigger is pulled, as the force of the firing pin spring is missing.
- the object of the invention is to create a lock system which allows a firearm with a shorter overall length, has an improved safety device and is also robust and insensitive.
- aiming aids such as a telescopic sight or a reflex sight or also a rear sight and front sight, or which has the line of sight.
- the lock system according to the invention is constructed in such a way that the actual components required for firing the shot, such as striking piece, striker spring, trigger bar, etc., are arranged above a locking track.
- the breech track is the track in which the lock runs when it is moved backwards from the position closing the chamber and then moved forward again to feed a cartridge from a magazine that is inserted in the magazine well insert the cartridge into the chamber and close the barrel to the rear behind the chamber.
- the safety mechanism is therefore also moved from the bottom to the top, with both the action of the trigger and the action of a safety slide being mechanically translated from the bottom to the top, around the lock, the barrel or a barrel receptacle.
- the striking unit of the lock i.e. the striking piece or a lever arm acting as a striking piece and lever elements connected to it, is designed as a toggle lever. If the hammer or the lever is moved into the cocked position and thus the mainspring is cocked, a trigger rod interacts with the hammer or this lever in a latching manner, the trigger rod being pressed into the detent with the pressure of a spring.
- the invention makes use of the fact that a toggle lever has a dead center in the fully extended state. If it is pivoted in one direction or the other, it assumes a mechanically more stable state from which it can only be brought back over dead center by external influence.
- the toggle lever is the essential feature of the invention.
- the safety device acts here in such a way that the toggle lever mechanism of the hammer and the mechanical parts that are operatively connected to it are pressed upwards against the direction of impact, which is a downward pivoting movement, and held there. So the toggle lever is moved upwards against the impact direction over the dead center and remains there in a mechanically stable position.
- the safety bar ensure that the striker cannot be moved in the direction of the striker because the movement is blocked, but the special feature of the toggle lever ensures that whatever force acting on the striker is exactly the opposite , ie away from the firing pin, acts.
- a particularly secure safety device is created which is far superior to known safety systems and manual tensioning systems.
- a simply constructed, robust lock for a firearm, in particular a special repeating firearm is formed which has a particularly reliable safety device and is also very robust due to its construction.
- the invention thus relates to a lock system for a firearm with an arrangement of at least two lever arms, the lever arms being articulated in the manner of a toggle lever with an axis or shaft, the toggle lever formed in this way on both sides of a dead point in which the arrangement is maximally stretched, is pivotable, one of the lever arms is designed as a striker for a firing pin.
- a pivoting direction on one side of the dead center closer to the firing pin defines an impact position and a pivoting to the other side of the dead center defines a safety position.
- the at least one lever arm acts on the axis of rotation under the pressure of a spring, so that the dead center has to be overcome against the pressure of the spring.
- a lever with a detent detachably counteracted with a Ge or surface of a trigger bar is designed to cooperate.
- the system comprising the lever arms is arranged on a weapon upper side above a locking track.
- a trigger translation lever is available to translate a trigger movement on a trigger tongue on a trigger bar arranged above the slide rail, which transfers the movement of a trigger slide located on the underside of the weapon to the top of the weapon, with the trigger translation Lever is arranged at a free end diametrically opposite a free end of the trigger bar and is articulated there and the trigger transmission lever is also articulated in the trigger slide on the underside of the weapon, the trigger transmission lever being guided around the components and / or a locking track lying between the upper side of the weapon and the lower side of the weapon, so that a movement of a trigger slide in one axial direction is translated into a counter-rotating axial movement of the trigger rod.
- the trigger rod engages in a tensioned, non-triggered position of the lock with the underside of a free end in a detent or a detent recess in the cylindrical region of one lever, the underside of one end of the trigger rod as a counter-locking element for a through the recess formed, transversely, ie with the first axis of rotation, it acts as a hammer axis of rotation, axially extending flat locking surface interacts so that the lock lay the lever assembly against the pressure of a spring on a shock bar, which is articulated to the other lever arm and from the trigger bar is held when the surface of the trigger bar rests on the surface of the lever.
- the trigger bar is arranged axially movable into the latching engagement between the surfaces and axially out of the engagement, the trigger bar being spring-loaded in the direction of the engagement, so that the release of the latching connection against the pressure of a spring must be done.
- the safety arrangement having a safety rod, the safety rod having means which are designed to cooperate with countermeans of one of the levers, such that the means move the toggle assembly of the hammer assembly to secure it from the hammer position over the dead center can pivot the locking position and for unlocking from the locking position over the dead center into the impact position.
- the lock has a striker arrangement which has a striker and at least one striker actuating lever arm, where the striker can be pivoted about an axis of rotation towards and away from a striker and at least one striker actuating lever arm on the striker with an axis of rotation is articulated, wherein the axis of rotation is arranged away from the axis of rotation on the hammer, wherein the hammer and the hammer actuating lever arm form a toggle lever which is pivotable about the axis of rotation on both sides of a dead center
- the fuse has two inclined surfaces as a means, which have a rectified inclined position and the means on the striker arrangement is a laterally protruding pin, so that the striker arrangement by sliding the pin along an inclined surface over the striker arrangement Dead center moves into the safeguarding and when moving the securing rod into the firing position, the inclined surface pushes the pin and thus the hammer assembly from the securing position through the dead center into the firing position or striking position.

- the trigger transmission lever 6 can be designed in such a way that it engages around the components that are located between the lock located on the upper side of the weapon and the trigger slide 7 arranged on the lower side of the weapon.
- These components can in particular be a barrel extension, a barrel with a cartridge chamber, the breech or an area in which the breech runs, namely the breech track.
- the trigger transmission lever 6 is designed, for example, as a ring which engages through the Boh tion 24 of the trigger rod 5 and in the same way either engages through the trigger slide 7 or is hinged to the actuating section 6a in the opening 7a.
- a fuse arrangement 40 is provided.
- the safety arrangement 40 comprises a safety rod 41, a safety transmission lever 42, a safety slide 43 and the driver pin 21.
- the safety arrangement ( Figures 3, 4) is a safety rod 41, in particular arranged parallel to the trigger rod 5, the safety rod 41 being axially movable with respect to the weapon longitudinal axis in the same way as the trigger rod 5.
- the safety rod 41 is flat and elongated with narrow sides facing up and down and broadsides facing laterally.
- the securing rod 41 is adjacent and to the side of which the driver pin 21 aufwei send Sch lay piece cheek 20 is arranged, preferably in close proximity or slightly adjacent.
- the securing rod 41 has from its upper narrow side 44 adjacent to the impact piece arrangement 2, a recess 45 which extends, for example, by the width of the driver pin 21 downward.
- the recess is continuously formed up to a lower narrow side 47, the recess 45 not extending from broad side to broad side of the securing rod 41, but rather the securing rod 41 on the broad side facing away from the Sch lay piece cheek 20 te is formed continuously, so that the recess 45 or groove 45 extends only over a partial width of the securing rod 41.
- the recess 45 deepens in the area of the free end 46, as already stated, towards the narrow side 47 lying below, an inclined surface 48 being formed.
- the end region 49 of the securing rod 41 is again fully formed, with a surface 49a extending obliquely from the bottom to the top being formed.
- the width of the recess 45 and the complete opening in the area of the free end 46 is dimensioned such that it corresponds approximately to the amount by which the driver pin 21 protrudes from the hammer cheek 20.
- the securing rod 41 is designed to be axially movable. In an ent secured position ( Figure 3), the hammer assembly 2 is in a cocked and ready-to-fire state. In this state, the driver pin 21 is located between the bevels 48, 49a and can thus be pivoted on the underside or downwards without touching the securing rod 41. A shot can therefore be triggered in this position.
- the safety rod is pushed towards the hammer assembly 2, whereby the driver pin 21 slides along the inclined surface 48 into the recess 45.
- the entire knee joint arrangement is raised in such a way that the axis of rotation 17 is located above the axis of rotation 9.
- the toggle lever arrangement is pivoted over the dead center in the counter-stroke direction, from which it - according to the nature of the toggle lever - cannot return without external influence.
- the striker rod 4 would execute a movement on the striker arm 8 or the toggle lever received an impulse in the direction of the dead point, the striker 8 would also be moved away from the striker 30.
- the force of the striker rod 4 thus has an additional protective effect, since the striker 8 is actively held away from the firing pin by the spring pressure of the striker spring.
- the driver pin 21 lies in the recess 45, whereby the movement is also made impossible in the direction of the firing pin.
- the safety rod In order to unlock the weapon, the safety rod is moved in the firing direction until the driver pin 21 is again in the area between the inclined surfaces 48 and 49a0. Even in this state, firing of a shot is not possible, since the striker rod 4 or the striker spring around the striker rod 4 (not shown) continues to hold the toggle lever arrangement comprising striker arrangement and striker actuating lever arrangement 3 away from the firing pin by the spring pressure.
- the safety rod 41 In order to move the lock into the firing position, the safety rod 41 is thus moved further in the firing direction, so that the driver pin 21 slides along the slope 49a and thus the lock or the toggle assembly consisting of the striker arrangement and striker actuation lever arrangement over the dead center of the toggle lever (after below) is moved to the firing position.
- the free end of the pull rod 5 In this firing position, the free end of the pull rod 5 is now again in the recess 25, so that the free end 22 and the Rastflä surface 26 are supported on each other under the pressure of the mainspring (not shown).
- the securing arrangement 40 has an anti-twist device for the closure via the securing rod 41. The breech is used to close the barrel to the rear and to feed the cartridge into the chamber.
- the closure 35 preferably has a locking pin 36, the locking pin 36 being arranged on a surface of the closure body.
- the securing rod 41 preferably has a lock or pocket formed on the underside which, in the secured state, is arranged around the securing pin 36 or around it so that the securing pawl 37 or securing pocket 37 prevents the lock from rotating in the opening direction.
- a securing transmission lever 42 is arranged on the securing rod 41 at a free end 45a of the securing rod 41, the free end 45a of the securing rod 41 being diametrically opposite the free end 46.
- the safety transmission lever 42 is designed, for example, around the breech and / or a pat ronenlager and can be designed in the same way as the trigger transmission lever 6 round, C-shaped or the like, wherein it rests in a hammer arm 51 of the safety rod 41, which is either the safety rod engages through the broad sides or is introduced from a lower edge 47 and rests on an opposite lying guide lever arm 52 in an opening of a bore or a recess of the safety slide 43.
- the safety translation lever 42 also has a fulcrum between the recesses 46 and the safety slide 43 in order to bring about a rotation about a pivot point, so that a pushing movement of the safety slide 43 against the firing direction moves the securing rod 41 in the firing direction and thus unlocks the lock system 1 .

- the catch 72 preferably runs with respect to the upper side 62 of the guide lever arm 52 or the lower side 63 sloping slightly outwardly.
- the detent 72 is angled downwards outwards, or at an angle of 3 to 25 °.
- a threaded bore 74 is introduced, which runs obliquely downward from the wall 73 to the surface 63 and approximately in the transverse center of the guide lever arm 52 between the front side 64 and the rear end area 65, which is used to receive a grub screw with which a trigger bar to be described later the detent length and thus the trigger path can be screwed in to adjust.
- the bore 74 is here for example closer to a surface 61, i.e. between the surface 61 and the slot 66 adjacent to the slot 66.
- a recess from the underside 63 is introduced from the front side 64, which, for example, extends over approximately half the extent of the guide lever arm 52 from the front side 64 to the rear side 65.
- the recess is designed in such a way that the lower side 63 including the cylindrical area 68 is spared in this area.
- the recess 75 extends into the guide lever arm 52, with the recess 75 having a recess roof 76 toward the top 62.
- the recess roof 76 has a front area 77 and a rear area 78 and a transition 79 between them.
- the front area 77 extends from the wall 73 in a semicircular arc.
- the front recess roof area 77 reaches the transition area 79 in that the spatial orientation of the recess roof 76 changes, so that the transition area 79 up to a recess end 80 of the rear recess roof area 78 in the direction of an underside 63 also extends with a semicircular cross-section towards the end of the recess 80, so that the front recess roof area 77 and the rear recess roof area 78 are angled to each other and in particular are inclined to each other at an angle of 25 to 50 °.
- the recess roof 76 is designed to be semicircular or in the shape of a segment of a circle for reasons of practicality and in particular for manufacturing reasons, but these areas can also be flat without further ado.
- the hammer lever arm 51 and the guide lever arm 52 form the toggle lever arrangement.
- the guide lever arm 52 can be pivoted up and down about the stub shaft 69, 70
- the hammer lever arm 51 can be pivoted up and down about the shaft 54 and both are connected to one another via the rotary guide shaft 58.
- the toggle lever arrangement formed from the hammer arm 51 and the guide lever arm 52 is acted upon by spring pressure via the hammer rod 4 and a Schlagfe arranged around it (not shown).
- the guide lever arm 52 is fixedly arranged by the shaft stub 69, 70 on the chassis of a firearm, while the hammer lever arm 51 and the hammer rod 4 can be moved in the firing direction and against the firing direction to a limited extent by pivoting the toggle lever arrangement.
- the toggle lever arrangement comprising hammer lever arm 51 and guide lever arm 52 is in a secured position when the rotary guide shaft 58 is located above the shaft stub 69, 70 (FIGS. 5, 6, 7) and in an unsecured, ready-to-fire position when the Rotary guide shaft 58 or its axis of rotation is located below the stub shaft 69, 70 or its axis of rotation (FIGS. 8, 9, 10) and in a cut-off position (FIGS.
- a securing rod 85 is provided for pivoting the guide lever arm 52 and thereby for guiding the secured and unsecured positions.
- the securing rod 85 is, for example, elongated and square and / or rectangular in cross-section with a top 86 and a bottom 87. Parallel to the top 86 and bottom 87, continuous guide slots 89 are provided in side walls 88, which are supported by corresponding bolts, shafts or the like (not shown) and hold the safety rod 85 only axially movable, but otherwise fixed on a firearm chassis.
- the safety rod 85 has a front end 90 on the firearm side, with a recess 91 for the lever 42 (not shown) already described with the first embodiment being present in the area of the front end 90 on the underside 87.
- the securing rod 85 also has a rear end 92.
- the underside with a control surface 93 is formed adjacent to the recess 91 to the rear end 92 and approximately on fleas of a slot 89, which the safety rod in its fleas between the underside 87 and the top 86 from the area of the recess 91 widened with a kind of Ram pe.
- the securing rod 85 is formed on its upper side 86 with a rounded portion 94, the rounded portion 94 being, for example, semicircular and / or having at least two bevels 94 on both sides, the free end 92 of the upper side being formed with a control bead 95 is, which protrudes round on the top.
- the bead 95 is designed so that it can interact with the recess 75 and in particular with the recess roof 76 and in particular has such a corresponding shape that it can interact with the recess roof 76 in a form-fitting manner or over the entire surface.
- the width of the securing rod 85 is dimensioned such that it corresponds to the width of the recess 75 or is slightly smaller, the bead 95 being curved in such a way that it can slide together with the front recess roof area 77 and the rear recess roof area 78, with a flat Formation of the roof areas of the bead is possibly only arched in the longitudinal direction, but is flat in the transverse direction.
- the securing rod 85 functions here as follows.
- An initial position is the unlocked, cocked position of the lock, in which, for example, after loading or firing a shot and repeating the lock is in a ready-to-fire state (FIGS. 8, 9, 10).
- control bead 95 is located at the entrance of the recess 75 in the area of the wall 73.
- the rotary guide shaft 58 is located below the axis of rotation 71 of the guide lever arm 52. If the lock is now to be secured, the safety rod 85 is directed against the firing direction Recess 75 moved into it. As a result, the bead 95 slides on the top side first along the front recess roof area 77 before it gets into the transition area 79 and then meets the rear recess roof area rich.
- the guide lever arm 52 Since the safety bar 85 cannot move up or down, the guide lever arm 52 is pivoted about the axis of rotation during a further forward movement, since the bead 95 slides along the sloping rear recess roof area 78 and thereby lifts the guide lever arm 52. Through this movement, the toggle lever assembly of hammer arm 51 and guide lever arm 52 is moved against the pressure of the hammer spring (not shown) on the hammer rod 4 and brought into the area of dead center in which the toggle assembly sits its greatest length be. When the bead 95 is pushed further into the recess 75, the guide lever arm and the hammer arm pivot upwards beyond the dead center (supported by the hammer spring), so that the secured position (FIGS.
- the securing rod 85 is moved in the firing direction, whereby a front side 96 of the bead 95 first reaches the area 79 and then moves into the area of the front recess roof area.
- the front recess roof area is then deflected by the front side 96 of the bead 95 against the force of the striker spring (not shown) and thus the toggle lever arrangement composed of hammer lever arm 51 and guide lever arm 52 is initially deflected to the dead point, in which the striker spring experiences the greatest compression and the toggle lever arrangement, has its greatest elongation based on the longitudinal axis of the weapon.
- the trigger bar 98 is arranged parallel to the safety bar 85, but approximately to the transverse center of the guide lever arm 52.
- the trigger bar 98 is also a square or rectangular bar in cross section with a free end (front) 99 and a free end (rear) 100.
- the trigger bar Aligned with the transverse recesses 89 of the safety bar 85, the trigger bar has recesses 101, which are of the same Bolts like the recesses 89 are penetrated to allow axial movement, but to prevent movement up or down.
- the trigger rod 98 has a recess 102 for a lever 6 with which the trigger rod can be actuated from the underside of the weapon.
- the trigger bar At its free end (rear) 100, the trigger bar has an area with a flat lower surface (not shown) which, like the first embodiment of a trigger bar, is designed to interact with the catch 72 of the guide lever arm 52 against rotation of the guide lever arm 52.
- a front end face 103 of the pull rod 98 which is usually arranged orthogonally to the lower surface, can bear against the wall 73 in the region of the bore 74.
- the position of the trigger bar 98 can be adjusted by means of a screw arranged in the bore 74. and in particular the degree of overlap between the catch 72 and the lower surface in the region of the free end 100 of the trigger bar 98.
- the trigger rod 98 and the safety rod 85 can have an abutment 104 on the top in the region of their free ends (front) 99, each of which has a receiving bore 105, in particular for a compression spring (not shown), with which both the safety rod ge in the direction of a secured position is pressurized as well as the trigger bar in a locked position.
- These compression springs are optional, but not mandatory, on the trigger bar.
- the lock system la has a locking bar 110 in an advantageous embodiment.
- the locking bar 110 runs parallel to the trigger bar 98 and is designed in the same way and also acts like a trigger bar 98, with an abutment 104 and a receiving bore 105 for a compression spring (not shown) also being present.
- the locking rod also has a lower surface (not shown) and an end surface 103 with which the locking rod can be brought into engagement with the catch 72 in the manner of the trigger rod.
- the locking rod 110 has a Steuervor jump 111 on the underside, with which the locking rod can be brought into locking engagement and thus the locked position and can be brought out of this.
- the task of the locking bar is to prevent the lock from knocking off when the lock is not in a forward position, but is behind the lock in the firing direction in relation to the longitudinal axis of the weapon. If the weapon were knocked off in this state and then the breech was moved forward, the breech would come against the knocked-off hammer arm 51 from behind and possibly damage the lock.
- the advantage of this embodiment is that the construction of the toggle lever solely by means of the hammer lever arm 51 and the guide lever arm 52 ensures a comparatively simple construction of the toggle lever arrangement.
- the hole in the guide lever arm enables the lock to be secured and unlocked very reliably, but also with little effort. It goes without saying that the above-described geometric configuration of the hammer lever arm 51 and the guide lever arm 52 can also be modified and, in particular, greatly simplified, for the implementation of the invention.
