Abstract

The invention relates to a firing mechanism having a cocking device for shooting weapons, consisting of a trigger, a cocking lever and an adjusting screw. The object of the invention is to create a design having few components and increased reliability. The invention comprises the trigger being provided with a tab for engaging with the tab on the cocking lever.

Description

The invention ее relates to a trigger mechanism with a firearm turnbuckle, which is arranged as a single tongue and solves the simplification of the trigger mechanism.

Known solutions are based on the requirement that the trigger run until the percussion mechanism is released is sensitive and gentle and that the weapon is safe. Sometimes it is necessary for the trigger mechanism to have a normal resistance and firing pattern. On the contrary, it is sometimes required, especially for very accurate shooting when using a telescope, that the trigger mechanism operates as smoothly as possible1 ·

The above mentioned requirements are fulfilled by the construction of a single-tongue trigger mechanism with a tensioner, where the firing is triggered by pulling the trigger tongue upwards until the lever of the tensioner engages the claw of the rotating catch. backwards when the catch turns to release the tensioner lever. This spring will accelerate the trigger flap further backward until the trigger lever is pivoted, the firing pin is released, and the firing trigger is triggered. Sensitivity and softness of the trigger can be controlled by the adjusting screw ·

The disadvantage of this arrangement is the large number of components that functionally connect to each other and quite a lot of space in the weapon, so many weapons can not be used for this reason.

These drawbacks are overcome by the invention, in which the trigger mechanism with a firearm tensioner consisting essentially of the trigger, the tensioner lever e of the adjusting screw, is designed such that the trigger is provided with a tooth for engaging the tooth of the tensioner lever.

Another aspect of the invention is that a spring is inserted between the tensioner lever arm recess and the longitudinal recess of the box frame longitudinally.

Essentially, it is necessary to include 1 that in the trigger there is a threaded control screw whose end is in cooperation with the support surface of the tensioner lever.

Finally, the last part of the essence is that the turnbuckle lever is provided with a surface for engaging the trigger pin.

The effect of the invention is to reduce the number of individual components by a rotating catch, resulting in reduced manufacturing costs, increased reliability of function and reduced space requirement in the weapon.

An exemplary solution according to the invention is shown in the drawing, in which Fig. 1 is a schematic arrangement of the trigger mechanism in the non-tensioned state; Fig. 2 represents a schematic arrangement of the trigger mechanism in the tensioned state;

The trigger 1 is rotatably mounted in the box 2 of the pin 3, is provided with a tongue 22, a tooth 13, a nose 9, a through hole 18 for the adjusting screw 8 whose end 16 is adapted to abut the abutment surface 17 of the tensioner lever 4.

The tensioner lever 4, rotatably mounted in the box 2 of the pin 5, has a tooth 19, a surface 12 adapted to engage the pin 3, an arm 7 with a recess 15 to hold the end 20 of the spring 6 whose second end 21 is mounted on the surface 23 14 of the box frame 2 · The nose 9 of the trigger 1 engages the trigger lever 10 which engages the firing pin 11 ··

The device according to the invention operates as follows:

By pressing the shooter's finger on the trigger tab 22 in the N direction, the trigger 1 is rotated about the pin 3 and the tensioner lever 4 is rotated by engaging the tensioner lever tooth and the trigger lever tooth until the teeth 13, 19 of the trigger 1 and the tensioner lever 4 engage · Depth of engagement It is given by the tensioner lever 4 at the end 16 of the adjusting screw 8 · By turning the tensioner lever 4 the spring 6 is compressed · The firing gun acts on the trigger 22 of the trigger 1 towards R · Oakmlle Resistance is overcome

CS 368 369 B1 of the trigger 1 against movement, the tooth 13 of the trigger 1 and the tooth 19 of the tensioner 4 engages relative to each other, and by the action of the spring 6 the tensioner lever 4 is turned up

In this case, the further action of the trigger 13 of the trigger 1 and the trigger 19 of the trigger tensioner 4 is accelerated by its tongue 22 in the R direction, so that the impact of the nose 9 of the trigger 1 causes the trigger 10 to swing.

When firing the firearm in the event that the tensioner 4 is not tensioned, the trigger swing 10 is caused by the nose 9 of the trigger 1 exerted by the shooter's finger pressure on the tongue 22, without accelerating the trigger 1. when using a turnbuckle ·
