RU2241942C1 - Firing mechanism of double-barreled gun - Google Patents

Abstract

FIELD: armament, applicable in sporting double-barreled guns.

SUBSTANCE: the firing mechanism of a double-barreled gun is assembled on a separate base and includes hammers, sears, trigger, spring-loaded disconnector and a safety lock. The novelty in the firing mechanism is in the fact that the disconnector has a spring-loaded trigger-lever plunger engageable with the copying surface and the supporting pad made on the safety lock fixing arm, which in its turn, is provided with a shoulder locking the trigger through the disconnector, the latter has a lug engageable with the recesses and profile surfaces formed in the triggers.

EFFECT: enhanced operating characteristics due to provision of the second shot at a misfire of the first one, prevented "doubled" shots, enhanced safety of weapon handling.

Description

The invention relates to weapons technology and can be used in hunting and sporting double-barreled guns.

Known trigger mechanism of a double-barreled gun [1], containing the base, trigger, whisper, disconnector, switch the order of shots.

The disadvantage of this mechanism is the impossibility of firing a second shot after the misfire obtained during the first trigger release, since for the second shot it is necessary to push (hit) the back of the gun’s butt, then the disconnector under the influence of inertia will come out from under the sear and then drop under the second was whispering and the gun was ready to fire.

The prototype of the invention adopted the trigger mechanism of a double-barreled gun [2], which includes a base, triggers, whispered, disconnector, button for switching the sequence of shots (fuse), support, lever.

In this mechanism, it is also impossible to produce a second shot in the event of a misfire after the first trigger release. To produce a second shot, it is necessary to transfer the fuse to its extreme rear position, while the lever will remove the disconnector from under the sear and after moving the fuse to the forward position, the disconnector will pop under another sear. These additional manipulations lead to inconvenience during operation. The mechanism provides for the exclusion of “double” shots due to contact after the shot of the copy surfaces in the back of one of the whispers with the corresponding surface located under the middle tooth of the disconnector at the time of the rifle, which does not give a 100% guarantee of protection from “double” shots, t. to. the trip time of the disconnector tooth under the second sear will largely depend on the efforts of the disconnector spring and the trigger.

The disadvantages of this mechanism should also include the fact that when setting the gun on the fuse, the disconnector and the sear are opened, while the trigger does not lock, i.e. it is possible to move the trigger needle and there is a feeling by the shooter that the gun is not in the “fuse” position.

The invention solves the problem of increasing operational characteristics by providing a second shot when misfiring at the first and eliminating “double” shots.

The problem is solved due to the fact that in the trigger mechanism of a double-barreled gun mounted on a separate base, including triggers, whispers, trigger, spring-loaded disconnector and fuse, new according to the invention is that the disconnector has a spring-loaded pressure switch in contact with the copy surface and supporting platform, made on the fuse holder, which, in turn, is equipped with a ledge locking the trigger through the disconnector, while the latter has a protrusion interacting with recesses and profile surfaces formed in the triggers.

Figure 1 shows the trigger mechanism when cocked, the fuse in the "fire" position, General view.

Figure 2 shows the trigger mechanism at the time of the shot.

Figure 3 shows the position of the parts of the trigger mechanism before the second shot.

The trigger mechanism includes a base 1, triggers 2, 3, sear 4, 5, trigger 6, disconnector 7 with spring 8, switch 9, operating spring 10. The triggers have recesses 11 and profile surfaces 12 for placement and contact with one of ledge 13 disconnector 7.

In the disconnector 7 there is a spring-loaded pressure switch 14, which is in contact with the copy surface 15 and the support pad 16 of the retainer 17 of the fuse 18, as well as the middle 19 and two extreme teeth 20 and 21, whispering alternately in contact with the platforms 22, 23. The latch 17 has ledges 24, locking the trigger 6 through the disconnector 7.

The trigger mechanism works as follows.

For firing a shot, it is necessary to move the fuse 18 to the “Fire” position, while the ledges 24 of the latch 17 release the disconnector 7 and, accordingly, the trigger 6, then you need to press the trigger 6, while the disconnector 7, interacting through the middle tooth 19 with the pad 22 4, will disengage it from the trigger 2. Trigger 2 under the action of the mainspring 10, turning forward, will hit the striker. A shot is taking place.

When you turn the trigger 2 with its profile surface 12 will hit the protrusion 13 of the disconnector 7, located in the recess 11 of the trigger. The disconnector 7, stretching the spring 8, begins to turn back, while the spring-loaded pressure switch 14 is in contact with the copy surface 15 of the latch 17, the disconnector 7 is braked.

The sear 5, released by disconnector 7, falls under the action of the spring. Under the action of the recoil trigger 6 comes out of contact with the finger of the hand. The trigger 6 under the action of the spring and inertial forces is lowered down. At the end of the turn, the inlet 14 of the disconnector 7 will disengage from the supporting platform 16 of the latch 17.

The disconnector 7 under the action of the spring begins to turn forward. At the same time, the rollback process of the gun is completed and, under the action of elastic forces, the gunner begins to move forward. The inertia forces of the disconnector 7 inhibit the rotation of the disconnector, slowing down the time of its rotation. With further movement of the gun, the trigger 6 rests on the finger arrow. An unauthorized shooter pulls the trigger. By holding the disconnector 7 in the back position by the support pad 16 of the latch 17 and slowing its forward rotation, the tooth 20 of the disconnector 7 does not have time to go under the platform 23 whispered 5. As a result, an unauthorized (“double”) shot does not occur.

To produce the second shot, release the trigger 6. In this case, the tooth 20 of the disconnector 7 becomes under the platform 23 of the whisper 5. When you press the trigger 6, a second shot occurs.

To produce shots in a different sequence, move the button of the switch 9.

The interaction of the details will be similar.

To put the gun on the fuse, you must move the fuse 18 back. In this case, the ledges 24 of the latch 17 rise above the disconnector 7 and, through it, the trigger is locked.

This design of the trigger mechanism is planned to be used in serial production of double-barrel sports and hunting rifles TsKIB SOO.
