Definitions

  • the invention is related with a locked breech mechanism for firearms which allows for slide/breech block and barrel locked together at the point of firing .
  • the inertia pushes the slide/breech block and barrel together for a certain distance .
  • the mechanism disengages after a certain amount of travel .
  • firearm capable of pushing bullet by the propulsion of powder gas.
  • firearm connotes any small caliber weapon carried by a person .
  • the firearms include all sorts of weapons of any si ze from huge cannon to ri fle and to pistol .
  • the principle of firing a proj ecti le from a firearm is that when the propellant in bullet ' s casing is ignited, the propellant burns quickly for a very short time . This creates a high-pressure pocket of gas that expands , pushing the proj ectile (bullet ) out of the chamber and down the barrel of the firearm . I f the high-pressure gas were not confined within certain parts of the weapon, it could damage the firearm or inj ure the shooter .
  • Recoil is described by Newton ' s third law of motion, which states that for every action there is an equal and opposite reaction . This force is felt in the hand or on the shoulder when a person fires a handgun or a rifle. It takes the form of a quick sharp push away from the path the bullet is flying in and directly against the hand or shoulder of the shooter .
  • Locked breech is a design of a breech-reloading firearm's action and one way to slow down the opening of the breech of a self-reloading firearm when fired.
  • the source of power for the movement is recoil.
  • muzzle flip refers to the tendency of a firearm's muzzle (front end of the barrel) to rise upwards when the bullet exits the barrel after firing. It's mostly influenced by the recoil energy which is rearward energy generated when a bullet is discharged. It varies mostly based on firearm design, buffer system, slide/breech block mass & travel distance, bullet weight, muzzle velocity, combined recoil from multiple shots being fired in quick succession etc.
  • Muzzle flip occurs when a projectile exits the muzzle of a barrel, the resultant energy release causes the barrel to move. Normally, because of the way firearms are held by humans, the flip is upward and slightly to the weaker holding side. One way of reducing the muzzle flip may be reducing the distance between the barrel axis and contact point of the grip.
  • the term "frame" means a part o f a handgun, or variants thereof , that provides housing or a structure for the component .
  • the frame is the lower portion/body of the pistol or firearm .
  • WO2019/ 029851A1 describe a breech block system for a firearm .
  • Breech block and barrel arranged movably, wherein a control block and a locking block arranged movably .
  • the locking block in a first position of breech-block system engages in an interlocking manner in the barrel , in the breech block and in the control block in such a way that the position of the barrel and the breech block in relation with one another is fixed .
  • a second position of breech-block system engages in an interlocking manner only in the barrel and in the control block, and so in this position the breech block is movable relative to the barrel .
  • control block is located under the chamber of the barrel which does not help to reduce the distance between the barrel axis and the contact point of the grip .
  • locking block and locking block extens ions are tiny and perhaps disadvantageous .
  • the other patent application numbered as US2011 / 0088304 describes a handgun having two s lides .

  • the invention is a new locked breech mechanism which allows for barrel (2) and slide (7) / breech (16) locked together at the point of firing by locking block (6.1) . While all locked parts move backwards, locking block (6.1) moves backwards and downwards and so pulled between locked parts.
  • Breech block (6) is mounted in the frame (21) which is lower body/portion of the firearm. More precisely all breech block (6) parts are mounted forward of the trigger guard (13) and below the barrel (2) in the frame (21) , allowing for shortening the distance between barrel (2) axis and contact point of the grip (10) .
  • Locking of the breech is provided by locking surface on barrel (22) , which is an area on the barrel (2) , which is almost perpendicular to barrel axis and so direction of the inertia and locking surface on slide (23) which is an area on the slide (7) , which is also almost perpendicular to slide axis and so direction of the inertia, are locked by locking block (6.1) .
  • Breech block (6) parts consists of locking block (6.1) , block link (6.2) , block link pin (6.3) and block spring (6.4) .
  • Breech block (6) may consist of one or more of the parts listed above.
  • new breech block mechanisms are also applicable for fixed barrel firearms with/without main spring (1) if magnitude of inertia allows.
  • the inertia pushes the slide (7) / breech (16) backwards for a certain distance.
  • Such movement pushes locking block (6.1) to move backwards and downwards and so allowing slide (7) / breech (16) disengaged.
  • Breech block (6) mounted the frame (21) allowing for shortening the distance between barrel (2) axis and contact point of the grip (10) .
  • Breech block (6) is designed such a way that keeps slide (7) / breech (16) , barrel (2) and locking block (6.1) together for certain amount of distance. At the same time, movement of locking block (6.1) and block link (6.2) provides locking block (6.1) is pulled between locking surface on slide (23) and locking surface on barrel (22) smoothly . While inertia pushes slide (7) / breech block (16) and the barrel (2) together for a certain distance. The combined weight of slide (7) / breech block (6) and barrel (2) helps to reduce the recoil. The mechanism disengages after certain amount of travel when locking block (6.1) is disengaged from slide (7) and barrel (2) .
  • a new slide (7) design is presented containing locking surface on slide (23) and notch (24) .
  • Slide (7) is connected to frame (21) with rails which allows for slide (7) moving on the frame (21) and around the barrel (2) .
  • the locking surface on barrel (22) is higher than locking surface on slide (23) .
  • the locking surface on slide (23) passes under the locking surface on barrel (22) since the height difference between locking surface on slide (23) and locking surface on barrel (22) .
  • Notch (24) on the slide (7) and locking surface on barrel (22) are at same height. While slide (7) is moving backwards under the barrel (2) , backward movement of slide (7) is stopped with notch (24) on the slide (7) and locking surface on barrel (22) .
  • Barrel is connected to frame (21) of the firearm by means of barrel pin (4) .
  • Barrel extension (3) has a horizontally opened barrel pin (4) housing, allowing barrel (2) can move backwards and onwards. Barrel (2) movement is limited with barrel pin (4) in both directions. When barrel (2) is moving backwards, it moves against the tension of the main spring ( 1 ) .
  • Main spring (1) tension is effective on slide (7) up to disengagement of slide (7) from barrel (2) .
  • Remaining main spring (1) tension is reserved for slide (7) stop.
  • slide (7) stop force is compensated by recoil spring (8) and remaining tension on the main spring (1) which helps for softer stop of the slide ( 7 ) .
  • Recoil spring (8) reciprocates the slide (7) onwards, while slide (7) is keeping the breech block (6) down and disengaged up to the end of the slide (7) travel.
  • Breech block (6) works in accordance with the principle explained above.
  • Breech block (6) consists of locking block (6.1) , block links (6.2) , block pins (6.3) and block spring (6.4) .
  • Breech block (6) keeps the slide (7) / breech (16) and barrel (2) locked at the point of firing. The inertia pushes slide (7) / breech (16) and the barrel (2) together for a certain distance.
  • locking block (6.1) moves backwards and downwards and so pulled between locked parts.
  • the breech block (6) disengages after a certain amount of travel when locking block (6.1) is disengaged from slide (7) and barrel (2) .
  • the height of the locking block (6.1) is different at barrel (2) side and at slide (7) side. Such height difference is needed to lock the locking surface on slide (23) and the locking surface on barrel (22) . So, locking surface on slide (23) moves under the locking surface on barrel (22) when breech block (6) is disengaged .
  • FIG. l.B an alternative breech block (6) is shown. It functions with same principle explained above but with less parts.
