UA57964U - Mechanism of non-automated safety lock of manual fire arms - Google Patents

Abstract

A mechanism for non-automated safety lock of manual fire arms includes trigger with safety lug for interaction with safety lug of safety lock that has locking boss and stopper that fixes the safety lock in positions “on” and “off”. The safety lug of the trigger is placed in front and higher than axis of its rotation. The safety lock is arranged as “cross slide” that is placed in front of trigger. The locking lug is formed by section A and section B that adjoin each other. Section A is formed as result of cutting three sectors of its cross section that are restricted with axles of symmetry. Section B is formed as result of cutting two opposite sectors of cross section that are restricted with axles of symmetry, at that one of those is continuation of sector at section A that is not cut.

Description

as an underbarrel grenade launcher, it can serve as a fuse in its channel and as a safety fuse for the underbarrel trigger in each variant of its grenade launcher, while maintaining the possibility of installation. setting the motor fuse from any side The fuse mechanism works as follows and the function of blocking from simultaneously appears. th pressing of the triggers of the machine gun and the grenade. To turn on the fuse (right version of the tomet. installation) Fig. 2 arrows click on the protruding one

The claimed mechanism of the fuse Fig. 2-3, place In the case of the use of the fuse mechanism, the trigger hook (1), the axis of the trigger hook (2), together with the shock-trigger mechanism under the barrel of the fuse motor (3), the lock of the fuse grenade launcher, Fig. 11, its trigger (4), the fuse lock spring (5) and the channel (20), which moves along the guides with its own to accommodate the fuse (6). The trigger rod (21), which has a safety protrusion (22) and a layer- consists of a tail (7), a safety protrusion (8), is connected to the trigger by means of a hole for a trigger rod (9), holes for an axis (10) of the axis (23) when the fuse (3) is turned on, the block and opening for lightening the weight and reducing it is kicked by its closing protrusion (12). At the output gear (11). The fuse motor (3) includes, in the closed state of the fuse and the pressed trigger, sections A and B of Fig. 7-8, by which the movement of the trigger hook formed by the locking hook of the machine gun (1), the switching protrusion (12), the channel for the latch (13), the grenade launcher (20) is blocked by the safety protrusion, the stop collar (14) and two holes (15) and ( 16) for (8) the trigger (1) that has gone down. When nati- lightening of weight. scan the trigger of the grenade launcher (20) its thrust

The channel for placing the fuse includes in (21) with its safety protrusion (22) two lugs, right (17) and left (18), which have a safety protrusion (8) of the trigger of the automatic machine, a cylindrical shape with a fi (1) and blocks it. Thanks to this property, the bellows groove (19) for interaction with the locking device prevents accidental or intentional simultaneous pressing of the fuse (4). At the same time, if the groove of the right ear is not possible to pull two triggers. turned forward, the groove of the left lug is 90" This design of the mechanism allows it to be significantly upward relative to the right one. This is due to the fact that to increase the reliability of operation and improve the figured grooves, in addition to fixing the fuse, the operational qualities of the sample of automatic weapons are also intended to prevent spontaneous rotation, which it will be applied.
