Definitions

  • the invention relates to a weapon closure system, d. H. a closure system for firearms.
  • Such systems are generally used to close a firearm with a shutter mechanism for delivering a shot, then open again, reload with a loading mechanism and to be able to deliver a shot again.
  • Closure systems with different loading mechanisms are known. Such systems are used to automatically load or reload an automatic or semi-automatic weapon. You can also operate manually. Incidentally, repeating systems for manual loading or reloading and for opening and closing a shutter mechanism are also known.
  • gas boosters are self-loading firearms in which the closure is firmly locked.
  • a part of the propellant gas is discharged from the pipe by one or more gas discharge (s) and supplied to a self-charging mechanism.
  • the energy of this under very high pressure propellant gas unlocks and opens the shutter and initiates a Nachladevorgang.
  • gas pressure charging systems direct the propellant gases through a gas pipe into the interior of the weapon.
  • the propellant gas is removed from the pipe via a gas take-off, but then fed via a pipe system to the closure, more precisely the closure carrier. There it acts directly on the closure carrier, which is driven by the direct propellant jet.
  • a pipe system is used for example in the standard rifle of the US armed forces M16 and the M4 carbine.
  • Rebound loaders have predominantly non-locked closure systems. They get the energy to eject a cartridge case and reload directly from the recoil energy of a shot. This acts directly on the front side of the closure head. This moves the entire closure so far back that the empty cartridge case is ejected and reloaded, such as when unlocked ground closure or semi-rigid roller shutter. Examples are the HK G3, the Israeli Uzi or the German submachine gun of the Wehrmacht -MP40.
  • firearms, gas pressure boosters, recoil loaders and also manual repeating systems have the disadvantage that they are not functionally reliable, usually at all when used out of a liquid, for example when surfacing from the sea or after immersion or after a stay in a liquid are not functional.
  • the liquid in particular water, penetrates into the interior of the weapon, in particular the weapon closure system.
  • gas pressure chargers without gas piston the liquid penetrates into the gas pipes of the gas pressure charging system.
  • the already described gas pressure charging system of the M16 or the Colt carabiner M4 runs full of water due to the missing gas piston.
  • the ignition of a cartridge can be prevented.
  • the necessary for ignition movable elements, such as the firing pin, can be slowed down so much of the liquid that, for example, the firing pin strikes only with an insufficient for a shot firing energy on the Zündplättchen.
  • the closure carrier and the closing spring piston are designed cooperatively in such a way that the closing spring piston displaces liquid from the at least one fluid passage opening when the closure carrier returns.
  • the weapon closure system comprises at least one fluid passage opening connecting a functional space, in particular a functional cavity, so that fluid which has entered the functional space and adversely affects the function of the closure system can easily and quickly pass through the fluid passage opening (s) outside is derivable.
  • Sol remain the functioning of the moving mechanical elements and the reliability of the closure system or a so equipped. Guaranteed weapon, liquid should have penetrated into the interior of the closure system or the weapon.
  • An inventive closure system can in principle be used in all types of weapons, from small arms to a mount fixed mounted weapons, such as automatic, semi-automatic, small caliber, large caliber weapons, such as assault rifles, machine guns, submachine guns, repeaters, light machine guns or grenade launcher - be it Gas pressure loaders, blowback or manual repeaters or weapons with other locking and charging system.
  • weapons from small arms to a mount fixed mounted weapons, such as automatic, semi-automatic, small caliber, large caliber weapons, such as assault rifles, machine guns, submachine guns, repeaters, light machine guns or grenade launcher - be it Gas pressure loaders, blowback or manual repeaters or weapons with other locking and charging system.
  • An inventive closure system is directly or at least after a very short time interval, for example, after the emergence of a weapons guide from the water - be it a combat diver or fighter, a member of a landing force or a special unit - Functional and reliable and allows a firing of a weapon equipped with it.
  • At least one fluid passage opening allows a targeted water or liquid channel guide, in particular such that - after a submergence of the weapon in a liquid - liquid penetrated into the weapon expire quickly and any liquid residues in a firing and reloading from the Inside the closure system or can be displaced from the weapon.
  • Several fluid passage openings in particular their clever arrangement and the resulting interaction, make the closure system according to the invention particularly robust against functional impairments due to penetrating water.
  • the at least one fluid passage opening can be configured and arranged as desired, as long as it guarantees a fluid outlet from the weapon.
  • it can be round, oval, tortuous, angular, in particular rectangular or triangular, or have any other shape.
  • an insert element such as a pipe, a box or other element suitable form of any materials, such as metal, plastic or the like can be used.
  • This may be fixedly connected to the fluid passage opening, for example, welded, glued, riveted, soldered, clamped or pressed, or, alternatively, releasably on and be releasably connected to the fluid passage opening.
  • a fluid passage opening can be integrated in any manner in a weapons locking system, for example by a hole or milling or by recesses, deletions or omissions in the manufacturing process, during extrusion or after.
  • the fluid passage opening is designed as a round bore into which a pipe section is inserted.
  • a Such a design can be cost-effective and allows a quick drainage of liquid.
  • the closure system further preferably comprises at least one closable closure and a closing spring mechanism and more preferably at least two functional spaces, in particular functional cavities (claim 6).
  • the closure may in principle be in one piece, but preferably comprises a closure carrier arranged thereon a closure head, more preferably in the closure carrier a functional space is arranged (claim 7).
  • This functional space is preferably a firing pin guide (claim 8), which usually comprises a firing pin, a firing pin spring and a schlagbolzenfeder entry (claim 9).
  • the front fluid passage opening may extend laterally, obliquely, radially upwards or downwards or otherwise. Preferably, it extends in the closure carrier, perpendicular to the axis of gravity weapon below the firing pin end as a radial bore down and is arranged so that it is adjacent to the closure head and below the firing pin is (claims 10, 11).
  • This arrangement has the advantage that the firing pin remains freely movable and functional, if there is a liquid here. It ensures a rapid drainage of the liquid or it can be easily displaced by the triggering of the firing pin from the firing pin guide area.
  • the firing pin can be actuated or triggered independently of the reloading mechanism and thus ensures the delivery of at least one shot from a weapon equipped with such a closure system.
  • At least one rear fluid passage opening is preferably located directly in the wall of the closing spring guide tube (claim 15) and / or in the shaft and / or in the shoulder support (claim 16).
  • the rear fluid passage openings may extend laterally, obliquely, radially upwards or downwards or otherwise (claim 17).
  • the weapon comprises in the rear region of the closure system at least two radial and three axial fluid passage openings in the wall of the closing spring guide tube and / or in the shaft and / or in the shoulder support.
  • the at least two fluid passage openings are arranged and configured such that they communicate with each other (claim 5), as this significantly increases the liquid channel guide.
  • At least one fluid passage opening in the closure carrier and at least five fluid passage openings in the closing spring mechanism are particularly preferably arranged (claim 20).
  • a functionality of the firing pin and other movable elements in one of the functional (hollow) spaces and a return of the closure is ensured.
  • the closure thereby can be activated both actively via a manual reloading, as well as passively via an automatic reloading.
  • the fluid passage openings are preferably also designed and arranged such that through them a fluid in the functional (hollow) space can be introduced (claim 3).
  • a gas can enter, so as to exclude a suction effect on the firing pin or any other blockade, for example, of the firing pin or the closing spring piston.
  • the drainage of a liquid is accelerated.
  • the closure system preferably comprises a closing spring housing and a functional (hollow) space arranged therein (claim 12).
  • a closing spring mechanism in this functional (hollow) space (claim 13).
  • This preferably comprises a closing spring piston, a closing spring, a closing spring guide tube and a closing spring piston buffer (claim 14).
  • the closure system preferably comprises at least one latching opening for longitudinal adjustment of the shoulder support and a radially arranged fluid passage opening (claim 18). Particularly preferably, two fluid passage openings are arranged in the latching openings.
  • the at least one fluid passage opening is particularly preferably arranged and configured in such a way that, after immersion or residence of the closure system in a liquid or other penetration of liquid into a functional (hollow) space, a liquid discharge within 1- Guaranteed 3 seconds (claim 19), as a particularly fast use of weapons is possible.
  • such weapons locking system according to the previous versions in weapons such as gas pressure, recoil or manual or other repeating systems used and usable, but it is particularly preferably used in a gas pressure supercharger.
  • a short stroke gas piston system is used with a short gas piston.
  • such a gas pressure loader comprises an actuating rod, a piston and a short cylinder (claim 22).
  • the piston is a short gas piston
  • the cylinder is a short gas cylinder
  • the actuating rod is a gas take-off rod.
  • This preferably extends from a gas take-off to the closure carrier and cooperates with the closure system in such a way that it drives the closure carrier and thus displaces liquid from the at least one fluid passage opening of the closing spring mechanism via the closing spring piston driven by the closure carrier (claim 23).
  • the gas rod and the closure carrier may or may not be coupled together. Preferably, however, the gas rod and the closure carrier are not coupled together.
  • At least one piston ring is preferably arranged on the gas piston, which bears against the inner wall of the gas cylinder. This removes deposited combustion residues there. With such a gas pressure supercharger, no propellant gases and corresponding propellant gas deposits reach the weapon interior. This shortens the cleaning effort and increases the reliability of the weapon.
