RU97822U1 - SHUTTER DELAY - Google Patents

Abstract

The utility model relates to small arms, more specifically to devices that lock the weapon in a safe position when the magazine is empty. To increase the practical rate of fire of a weapon, a slide delay containing a lever mounted on an axis in the receiver and protruding beyond the bottom of the weapon receiver contains a shutter stop connected to the lever located inside the prefabricated housing, and the lever is mounted to interact with the weapon store feeder. In this case, the shutter stop can be connected with the lever detachably. Additionally, to increase the reliability of the shutter lag and improve the safety of using weapons, the shutter stop or lever can be spring-loaded.

Description

The utility model relates to bolt delays, that is, to mechanisms that keep the bolt in its extreme rear position by using up all the cartridges in the magazine.

From the prior art, carbines hunting smooth-bore "Saiga", produced since 1993, containing a jumper installed in the receiver, are known. A protrusion of the reflector is made on the jumper to eject the spent sleeve, as well as a protrusion for attaching the magazine.

The shutter lag is known from the prior art (Operating Instructions SK-308.RE “Saiga-308-1”, self-loading hunting carbine, p.13, fig. 09-12, published at: http://talks.guns.ru/ forummessage / 56 / 61259-2.html) containing a spring-loaded lever mounted in the receiver on the axis. The slide delay allows you to put on it the moving parts of the gun to facilitate the attachment of the equipped store. To do this, move the movable parts back to the stop and drown the bolt lever protruding beyond the bottom of the receiver, and holding it gently release the moving parts with your hand. After this, attach the equipped magazine to the gun and remove the moving parts from the slide delay. To remove the moving parts from the slide delay, it is necessary to take the moving parts back to the stop and release them sharply.

The objective of the proposed utility model is to increase the practical rate of fire of the weapon due to the fact that the shutter is delayed automatically when the magazine is empty, and the shutter is removed from the delay using the lever.

To accomplish this task, the shutter lag, containing a lever mounted on the axis of the receiver and protruding beyond the bottom of the weapon receiver, includes a shutter stop connected to the lever, located inside the prefabricated housing, and the lever is mounted to interact with the gun store feeder. In this case, the shutter stop can be connected with the lever detachably.

Additionally, to increase the reliability of the shutter lag and improve the safety of using weapons, the shutter stop or lever can be spring-loaded.

The utility model is illustrated in the drawing (figure 1).

The slide delay comprises a lever 1 mounted in the receiver on the axis 2, a stop 3 of the shutter 4 containing a groove 5 into which the lever 1 is inserted. When the magazine is empty, one end 6 of the lever 1 interacts with the feeder 7, and the other end 8 projects beyond the bottom of the receiver 9. Stop 3 of the shutter 4 is placed inside the housing, composed of the upper 10 and lower 11 parts, fastened to each other by a thread.

Moreover, in the case of installing the proposed gate delay in a weapon known from the prior art containing a jumper, a prefabricated housing with a stop 3 of the shutter 4 can be placed inside the jumper (not shown).

To prevent unauthorized operation of the bolt delay during firing, the bolt delay can be equipped with a spring 12 acting on stop 3 or a spring 13 acting on lever 1. In this case, spring 11 is set to stop 3, and stop 3 is equipped with a nut 14 that limits the movement of the spring 11 along stop 3.

Shutter lag works as follows.

When the equipped magazine is connected to the weapon, the end 6 of the lever 1 is at the lower point. When the magazine is empty, the feeder 8 acts on the lever 1, moving the end 6 to the highest point. Due to the fact that the lever 1 is inserted into the groove 5, the stop 3 of the shutter 4 moves to the zone of movement of the shutter 4 while the shutter 4 is retracted. Under the action of the bolt spring, the bolt 4 begins to move forward and becomes stopped 3. After that, the empty magazine is disconnected from the weapon and the equipped magazine is installed. To remove the shutter 4 from stop 3, it is necessary to drown the end 8 of the lever 1, protruding beyond the bottom of the receiver 9.

Due to the presence in the design of a shutter connected to the stop lever located inside the prefabricated housing, and a lever installed to interact with the weapon magazine feeder, the shutter is delayed automatically when the magazine is empty. This increases the practical rate of fire of the weapon. An additional increase in the practical rate of fire is achieved due to the possibility of removing the shutter from the delay by acting on the end of the lever located close to the trigger.

The execution of the hull is prefabricated, it allows equipping weapons with automatic shutter lag, both in mass production and in the modernization of previously manufactured products. Moreover, in the case of installing the proposed gate delay in a weapon known from the prior art containing a jumper, the composite housing with a stop can be placed inside the jumper.
