Definitions

  • the invention relates to a lock system for a firearm according to the preamble of claim 1.
  • the lock system for a firearm is to be understood below as meaning the arrangement of functional components that serve to fire the shot, including the components that serve to secure the system and in particular to temporarily fix the components used to fire the shot.
  • Firearms have different lock systems depending on their design.
  • WO2008086545 A1 discloses a toggle lock system.
  • drop-barrel weapons there are flash locks, box locks and side locks.
  • a break-barrel weapon for example a shotgun, a break-barrel rifle, a double rifle or a treble
  • the locks are cocked, i.e. a hammer is moved against the spring pressure of a main spring into a non-released, spring-loaded position and fixed there with a detent .
  • This detent position can be released with the aid of the trigger, so that the hammer hits a firing pin under the pressure of a firing spring, which emerges from a firing pin opening and presses in the primer of a cartridge and thereby ignites it.
  • the firing pin In the case of rotary chamber breeches of bolt-action rifles, the firing pin itself is brought into operative connection with the firing spring or is in operative connection with it, with the firing spring opening (in rare cases also closing) the breech and thus locking the chamber in the barrel or in a case head is stretched.
  • a firing pin nut is usually located at an end of the chamber axially opposite the cartridge chamber, which is moved backwards when the breech is opened or closed and thus tensions the firing spring.
  • the firing pin nut When the bolt breech is pushed into the sleeve, in which the rotary bolt breech is mounted so that it can move axially, the firing pin nut is blocked axially by a detent, so that the tension of the mainspring is retained.
  • the catch By pulling the trigger, the catch is usually lowered so that the firing pin is abruptly moved forward under the spring pressure of the firing spring, emerges from the breech head of the chamber and ignites the cartridge.
  • swivel head breeches such as are usually found on semi-automatic firearms and, in some cases, also on fully automatic firearms, the recoil of the breech causes a hammer to be pressed into a latched position and held there by a latch against the pressure of a firing spring.
  • the hammer can also pivot forwards in the direction of the firing pin and strike the firing pin by releasing the locking connection by actuating a trigger
  • the firing pin is spring-mounted within the rotating head breech and, by striking the hammer on the back, also shoots forwards out of the breech head and ignites a cartridge via the primer.
  • the breech can thus be an integral part of the breech, as in the case of rotary chamber breeches of repeaters (where the firing pin nut is sometimes also referred to as the breech), but it can also be functionally separate from the actual breech, as in break-open rifles.
  • the lock is to be understood as that functional unit which interacts to trigger the shot and also includes a fuse.
  • the structure is determined by the functions.
  • Such firearms have a barrel to direct the projectile and also ensure the development of gas pressure, then a breech that tightly closes the barrel backwards at the moment of firing and holds the cartridge in place, magazine or other Cartridge feed area from which the bolt, moving towards the barrel to lock it, pushes a cartridge out and into the barrel chamber before locking the chamber backwards and then the lock, which includes the hammer, usually a trigger bar or a comparable component, and the trigger.
  • the detent and counter-detent are formed on the hammer and on the trigger rod, which interact to hold the hammer back in the cocked state of the hammer and thus the lock.
  • the firing spring is present, which keeps the hammer under tension when cocked in order to enable a very rapid movement towards the firing pin.
  • handguns are then followed by a shoulder piece in order to be able to draw the weapon into the shoulder when the shot is fired, in order to enable precise target acquisition on the one hand and cushioning of the recoil on the other.
  • a minimum overall length is predetermined, at least between the cartridge chamber, magazine well, lock and shoulder rest attachment due to the type of construction.
  • the safest is the so-called firing pin safety, because it secures the last functional component in front of the cartridge's primer against displacement, even if the lock is accidentally released.
  • the so-called rod safety which secures the trigger rod so that if the trigger is accidentally released, the trigger rod is not moved and thus the catch of the trigger rod and the counter catch of the hammer or the firing pin nut are not disengaged.
  • Even the rod safety is less secure than the firing pin safety, since it cannot be ruled out that external influences, such as falling or falling, will nevertheless loosen the latching connection and the hammer hits the firing pin and fires a shot.
  • a third known safety 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 safety has an even lower safety potential compared to the two aforementioned safety devices, since the mechanical chain of trigger bar and hammer or firing pin nut is not secured here and can also be loosened by impact or impact.
  • the object of the invention is to create a lock system that allows a firearm with a shorter overall length, has improved security and is also robust and insensitive.
  • this is the side of the weapon when the shooting position is correct, such as the ejection window for cartridges.
  • the lock system according to the invention is constructed in such a way that the actual components required for firing the shot, such as the hammer, main spring, trigger rod, etc., are arranged above a slideway.
  • the slide track is the track in which the slide runs when it is moved backwards from the position that closes the cartridge chamber and is then moved forwards again to feed a cartridge from a magazine that is in the magazine well in order to insert the cartridge into insert the cartridge chamber and close the barrel backwards behind the cartridge chamber.
  • the safety mechanism is also moved from the bottom to the top, with both the effect of the trigger and the effect of a safety slide being mechanically translated from the bottom to the top, around the breech, the barrel or a barrel mount.
  • the hammer unit of the lock i.e. the hammer or a lever arm acting as a hammer and lever elements connected thereto are designed as toggle levers. If the hammer or the lever is moved into the cocked position and the mainspring is thus cocked, a trigger bar engages with the hammer or this lever in a latching manner, with the trigger bar being pressed into the detent by the pressure of a spring.
  • the invention makes use of the fact that a toggle lever has a dead center when it is fully extended. 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 the dead center by external influence.
  • the toggle lever is the essential feature of the invention.
  • the safety device works in such a way that the toggle lever mechanism of the hammer and the mechanical parts that are operatively connected thereto are pressed upwards against the direction of impact, which is a downward pivoting movement, and is held there. So the toggle lever is pushed up past the dead center against the impact direction and remains there in a mechanically stable position. Not only does the safety bar ensure that the hammer cannot be moved in the direction of the firing pin because the movement is blocked, but the special feature of the toggle lever ensures that any force acting on the hammer is exactly the opposite, i.e. away from the firing pin.
  • a particularly secure fuse is created that is far superior to known security systems and manual cocking systems.
  • the advantage of the invention is that a simply constructed, robust lock for a firearm, in particular a 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 to an axis or shaft in the manner of a toggle lever, with the toggle lever formed in this way being pivotable on both sides of a dead center in which the arrangement is maximally stretched is, wherein one of the lever arms is designed as a striking piece for a firing pin.
  • a pivoting direction on one side of the dead center closer to the firing pin defines a striking position and 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 must be overcome against the pressure of the spring.
  • a lever with a detent is detachably designed to interact with a counter-detent or surface of a trigger rod.
  • the system comprising the lever arms is arranged on a weapon top above a breech track.
  • a trigger lever that transfers the movement of a trigger slide located on the underside of the weapon to the upper side of the weapon, with the trigger lever on a , a free end of the trigger rod is arranged diametrically opposite the free end and is articulated there and the trigger transmission lever in the trigger slide is also articulated on the underside of the weapon, the trigger transmission lever being guided around the components and/or a slideway between the upper and lower sides of the weapon, so that a movement of a Trigger slide is translated in an axial direction in an opposite axial movement of the trigger rod.
  • the underside of a free end of the trigger bar engages in a detent or a detent recess in the cylindrical area of one lever, with the underside of one end of the trigger bar acting as a counter-locking element for a Recess formed, transversely, i.e. with the first axis of rotation, which acts as the axis of rotation of the hammer, interacts axially running flat locking surface, so that the lock holds the lever arrangement against the pressure of a spring on a hammer rod, which is connected to the other lever arm in an articulated manner and is held by the trigger rod when the surface of the trigger bar is in contact with the surface of the lever.
  • the trigger rod is advantageously possible for the trigger rod to be arranged such that it can be moved axially into the latching engagement between the surfaces and axially out of the engagement, with the trigger rod being spring-loaded in the direction of engagement, so that the latching connection can be released against the pressure of a spring must take place.
  • a safety device with the safety arrangement having a safety bar, with the safety bar having means which are designed to interact with counter-means of one of the levers, such that the means activate the toggle lever arrangement of the hammer arrangement for safety from the striking position beyond the dead center in can pivot the safety position and unlocking from the safety position over the dead center in the impact position.

  • These compression springs are optional on the trigger bar, but not mandatory.
  • the lock system 1a has a locking bar 110.
  • the locking rod 110 runs parallel to the trigger rod 98 and is designed in the same way and also acts like a trigger rod 98, with an abutment 104 and a receiving bore 105 for a compression spring (not shown) also being present.
  • the locking bar also has a lower surface (not shown) and an end face 103, with which the locking bar can be brought into engagement with the catch 72 in the manner of the trigger bar.
  • the locking bar 110 has a control projection 111 on the underside, with which the locking bar can be brought into and out of the locking engagement and thus the locked position.
  • the task of the locking bar is to prevent the lock from being knocked off if the lock is not in a front position, but is located behind the lock in the firing direction in relation to the longitudinal axis of the weapon. If the weapon were to be cut off in this state and the breech then moved forward, the breech would hit the broken off hammer arm 51 from behind and possibly damage the lock.
  • Another advantage is that the hole in the guide lever arm enables a very reliable, but also energy-saving locking and unlocking of the lock.
