RU2763612C1 - Firearm shutter design and method for the shutter manufacturing - Google Patents

Abstract

FIELD: firearms.

SUBSTANCE: design of the bolt of a firearm, in which the bolt covers the barrel, that in the bolt with the striker located in the central hole, the striker in the form of a rod is located in the channel made in the part that closes the barrel and in the part of the bolt that covers the barrel. The impact from the striker to the striker is made through the transmission mechanism. A method for manufacturing a shutter is proposed, in which a long rod with longitudinal channels is rolled, then cut into blanks for shutters and a plug is installed in the channel designed to cover the barrel, and it is fixed. The plug is designed to grip the cartridge, chamber it and lock the barrel together with the bolt.

EFFECT: eduction of the length of the bolt locking part of the barrel, simplification of the shutter manufacturing technology.

Description

The invention relates to the field of armaments and can be used in hand firearms, which have automation due to the recoil of the shutter or the removal of gases.

From the book “All about Pistols and Revolvers” (Babak F.K. Sib., Polygon Publishing House LLC, 2003, p. 146), the device of the Stechkin I.Ya. The figure on page 146 shows the striker, which is located in the central channel of the shutter.

The author does not know anything about the technology of manufacturing a shutter from a bar rolled especially for this technology.

The disadvantage of a weapon with a central location of the striker is the large length of the shutter, the location of the firing mechanism in the frame behind the magazine, and the expensive technology for manufacturing the shutter.

The objective of the invention is to reduce the length of the locking barrel part of the shutter and to simplify the manufacturing technology of the shutter.

This problem is solved due to the fact that in the shutter covering the barrel with the location of the drummer in the form of a rod in the central channel, the drummer, in the form of a rod, is installed in the channel made outside or inside the shutter and in the part locking the barrel and in the part covering the barrel out of alignment with the barrel .

The drummer has the ability to move out of the bolt and strike the striker through the transmission mechanism installed in the part of the bolt that locks the barrel and move into the bolt when it rests against the rear wall of the weapon body during the "rollback" of the bolt after the shot.

The technical result of this solution is to reduce the length of the locking part of the bolt. A method for manufacturing a shutter is also proposed. It consists in the fact that first a long rod with channels is rolled (wired), after which blanks for shutters are separated with transverse cuts and a plug is inserted and fixed into the channel designed to cover the barrel, which will send the cartridge and lock the barrel during operation of the shutter.

The essence of the invention is illustrated by the drawing, where in Fig. 1 shows a weapon with local sections of the body and bolt and on which the letters indicate: ST - stopper, CM - trigger, R - lever (transmission mechanism schematically); in fig. 2 - cross section of the shutter and body along the stopper; figure 3 - profiles rolled rods.

In the shutter 1, a channel 2 is made for its entire length, in which the drummer 3 is placed with the ability to move out of the shutter and slide into it.

The shutter works like this. Pick up a weapon and pull the trigger of the SM trigger. Then the stopper CT will fall off the cocking of the firing pin. The drummer will move out of the bolt and act on the firing pin. There will be a shot. The shutter will “roll back” and the drummer will rest against the rear wall of the case. The drummer will cock. Next, the shutter captures the cartridge, chambering it and locking the barrel. The shutter is ready for the next firing cycle.

The method of manufacturing the shutter of a firearm is carried out in accordance with the claims and description.

The technology of rolling (drawing) rods, fixing the plug can be any of the known ones.

Claims (2)

1. The design of the bolt of a firearm, in which the bolt covers the barrel, and the drummer in the form of a rod is located in the central channel of the part of the bolt that locks the barrel, characterized in that the drummer in the form of a rod is located in the channel made outside or inside the bolt and in the part that locks the barrel and in the part covering the barrel, out of alignment with the barrel, with the ability to move out of the bolt and strike the striker through the transmission mechanism located in the part locking the barrel, and slide into the bolt while resting against the rear wall of the weapon body during the "rollback" of the bolt after the shot. 2. A method for manufacturing a shutter, which consists in the fact that first a long rod with longitudinal channels is rolled or wired, after which blanks for shutters are separated by transverse cuts, and a plug is inserted and fixed into the channel designed to cover the barrel, which will send the cartridge and lock the barrel when the shutter is working.
