Another patents in same IPC classes:

Pistol / 2278343

The pistol has a barrel, body, firing mechanism with a trigger, and a cartridge clip with cartridges. A slot for the forefinger is made on the outer side in parallel with the body barrel, the trigger for the thumb is installed on the other side of the body.

Small-arms trigger mechanism / 2311601

The small-arms trigger mechanism has a spring-loaded sear, intermediate sear and a spring-loaded trigger. The trigger is made hollow. The intermediate sear is fastened inside the trigger on a common axle, it is made double-arm with one arm positioned vertically, and the other-horizontally. The vertical arm of the intermediate sear is permanent engaged with the spring-loaded sear for engagement with the front wall of the trigger. The horizontal arm is made for engagement with the lower edge of the trigger front wall.

Error neutraliser / 2331032

Invention relates to small-arms weapon. The invention for error compensation while firing small-arms weapon is meant for putting it between fingers of a shooter and trigger, and is made in the form of two platforms which can move towards each other over the contact surface. One of the platforms is made so as to interact with the finger of the shooter, and the second one to interact with the trigger. The device can be supplied with an additional platform, which is located between the said two platforms. Note, all platforms are provided with devices which return them to the initial position and are made as a thin resin fixed on the platforms. The platforms can be joined with each other by dovetail connection.

Small arms replaceable magazine / 2355974

Invention relates to small arms, particularly, to repeating fire rifles. The rifle comprises a breechblock and detachable magazine with trigger bow and trigger attached to its bottom. The rigger assembly can be removed from the rifle together with the detachable magazine.

Trigger assembly with locator / 2355975

Invention relates to small arms. The trigger assembly comprises a latch, sear, spring, trigger and extra grooved hook to be shifted along the gun lengthwise axis and locked at required position.

Bull pup gun trigger mechanism / 2525464

Invention relates to weapons. Trigger mechanism comprises trigger, lengthwise link arranged along left inner side of breech box under structural web and above autorelease and trigger pins. One end of said link is connected with trigger and opposite end is connected with adapter fitted on the pin of standard trigger. Or, directly with standard trigger adapted to link connection.

(57) Abstract:

The scope of the invention: sniper rifles, which uses a trigger warning. The invention consists in the following: trigger made spring loaded and connected through a rod with septula, which is installed on the axis. The deadlift performed two tabs to interact with septula and window to allow free operation whispered. The invention allows to create a trigger warning, which will provide reliable retention cocked. 2 Il.

The invention relates to small arms and can be used, for example, sniper rifles, which uses triggers a warning.

A device trigger warning, providing signal since the collapse of the trigger with the sear (see the book by A. A. Blagonravov of the "Material part of the small arms survey, book 1, Barongis the NCAP, Moscow, 1945, page 106), which has a trigger, rotating on its axis, while its projection head resting against the wall of the receiver and the dewatering whispered, compressing the spring release lever, in the last mammoliti pressed on him. This increase is a warning arrow that very slight rotation of the trigger will lead to the final tripping the sear with a combat platoon trigger.

The disadvantage of this device is the lack of free running trigger that increases the probability of a random shot.

The prototype was taken to the device trigger warning, providing a signal of the beginning of the engagement of the trigger with septula (SU 1820168 A1, F 41 A 19/00, 07.06.1993), which has a spring-loaded trigger with a free stroke, rotating on its axis and its projection head resting against the wall of the receiver. Free running trigger can be adjusted. When turning the trigger abuts the ledge on septile, which leads to an increase of the pressing force on him, this increase is a warning arrow that subsequent very slight rotation of the trigger will lead to the final tripping the sear with a combat platoon trigger.

The disadvantage of this device is a complex interaction scheme that increases the probability of a random shot.

The technical result obtained by carrying out the invention, is to increase the operating reliability of the weapons.

This technical result is achieved by the fact that in the known trigger mechanism having a trigger, a sear, a trigger, two tabs, it trigger made spring loaded and connected through a rod with septula mounted on the axis, with the two tabs are made on the deadlift to interact with septula, with the possibility of free running.

Compared with the prototype of the proposed technical solution has the following distinctive features:
- trigger spring made;
"the trigger through the cravings associated with septula;
- sear mounted on the axle;
two tabs are made on the deadlift to interact with septula;
whispering has the opportunity to freely turn.

The above distinguishing features provide increased reliability trigger warning, because this device provides overtravel trigger.

Thus the proposed solution has a "Novelty" and "Inventive step".

In Fig. 1 from the and from the trigger.

The trigger mechanism includes a trigger 1, spring spring 2 mounted on the axis 3 and having a head 4 for communication with a thrust of 5, which made the two tabs 6 and 7 to communicate with septula 8 and box 9 to provide free motion of the sear 8, rotating on the axis 10 and interacts with the trigger 11.

The trigger mechanism works as follows.

When pressing the trigger 1, the head 4 pulls forward rod 5, and the first time you select the free space of the window 9. When the contact protrusion 7 and whispered the last 8 starts to split, with the trigger 11, at the last moment before the final disengagement with septula 8 begins to interact with the protrusion 6, which leads to abrupt increase in resistance to rotation of the trigger and is a warning arrow.

Trigger warning for a firearm that contains a spring-loaded trigger, sear, set on an axis, a trigger, means of prevention, including two tabs, characterized in that the means of prevention is a rod connecting the trigger with septula, both protrusion placed on the deadlift for engagement with the sear is
