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 invention relates to small arms and can be used in the manufacture of hunting rifles. The closest in technical essence of the prototype - is the trigger sporting rifles (ed. St. USSR №929989, F41 19/00)containing the base, trigger, main and intermediate whispered, lever and spring shutter is hinged in the upper part of the intermediate sear adjustable support, with the tab on the upper arm in contact with the lever, and an adjusting hole in the lower arm, the intermediate septal made adjusting holes, and the combined pair of holes on the support and the intermediate septal has a restraining pin. The disadvantage of the trigger is the low reliability due to the possibility of establishing engagement whispered close to zero, which can lead to spontaneous breakdown whispered with intermediate whispered when reloading or concussion weapons. The disadvantages of the known trigger mechanism should also include excessive design complexity due to the presence of such details as the lever, the node adjustment, as well as the inconvenience of Assembly. The technical result is to increase the reliability of the trigger mechanism, simplifying its design and ease of Assembly. For the achievement is of a technical result in the release mechanism of small arms, containing a spring-loaded sear, intermediate sear and spring-loaded trigger, the trigger is made hollow, intermediate sear attached inside the trigger on the same axis and made two shoulders with the location of one shoulder vertically and the other horizontally, with a vertical shoulder intermediate whispered performed with a constant mesh with the intermediate septula and interoperable with the front wall of the trigger, and a horizontal shoulder made interoperable with the bottom edge of the front wall of the trigger. In addition, whispered provided with an annular ledge located above the side wall of the trigger, with the center of the circle coincides with the axis whispered. The invention is illustrated in the drawing, which shows the trigger mechanism of small arms in the cocked position. The trigger mechanism includes a spring-tensioned spring 1 sear 2 and the spring hollow spring 3 trigger 4, inside which, on the same axis 5, is fixed intermediate sear 6, made two shoulders, while its vertical shoulder 7 is made with a constant predetermined's engagement with septula and communicates with the front wall 8 of the trigger, and a horizontal shoulder 9 is located below the bottom edge 10 of the front wall and the trigger. Whispered provided with an annular projection 11, is placed above the side wall 12 and the trigger. The center 13 of the annular protrusion coincides with the axis 14 whispered. On septal withheld drummer 15. The trigger mechanism for firearms is as follows. When the trigger is pulled, 4 he povorachivaetsa, while its lateral wall 12 is out of the annular protrusion 11 sear 2. Upon further turning of the trigger, the lower edge 10 of the front wall 8 of the hook clicks on a horizontal shoulder 9 of the intermediate sear 6, and outputs the vertical shoulder 7 out of engagement S septula. Drummer 15 turns whispered, breaks with him. Is shot. When you release the trigger it under the action of the spring 3 is rotated and pressed the trailing edge 16. 1. The trigger mechanism for firearms, containing a spring-loaded sear, intermediate sear and spring-loaded trigger, wherein the trigger is made hollow, intermediate sear attached inside the trigger on the same axis and made two shoulders with the location of one shoulder vertically and the other horizontally, with a vertical shoulder intermediate whispered performed with a constant engagement with the spring-loaded septula and interoperable with the front wall of the JV is the risk of the hook, and the horizontal shoulder made interoperable with the bottom edge of the front wall of the trigger. 2. The trigger mechanism according to claim 1, characterized in that the sear is equipped with an annular ledge located above the side wall of the trigger, with the center of the circle coincides with the axis whispered.
