Description

The invention relates to sporting ^{1 * * *} hunting weapons and is a trigger for a double-barreled gun.

Known trigger double-barreled shotgun containing one ⁵ trigger, whispering, uncoupler with a spring and a sequence of shots [1].

A disadvantage of the known mechanism is the large magnitude of the trigger stroke when fired from the second barrel, which negatively affects the accuracy of shooting.

The trigger of a double-barreled shotgun is also known, containing a trigger, whisper, trigger, inertial disconnector and a spring-loaded selector with a latch mounted on it with a beveled tooth [2). _m

The disadvantage of this device is that it does not provide increased trigger force and a small stroke of the trigger during the second high-

/ arrow, which degrades the performance of the weapon.

The purpose of the invention is to improve the operational characteristics of the mechanism.

This goal is achieved by the fact that in the trigger mechanism, the trigger, whisper, trigger, inertial disconnector, spring-loaded selector and retainer with a tooth, the inertial disconnector is made in the form of a freely swinging lever with a tooth, interacting with the selector, the lock is mounted on the same axis as the trigger hook, and on the selector formed the upper and lower protrusions that interact respectively with the tooth of the retainer and with the sear.

The drawing shows the trigger of a double-barreled shotgun, a General view.

The trigger mechanism is assembled in the block 1. on the base 2, on the axis 3 of which the trigger 4 and the spring-loaded latch 5 / are pivotally mounted. 929988 with tooth 6. In the trigger 4, a spring-loaded selector 7 is pivotally mounted, having a protrusion 8, interacting with the tooth 6 of the retainer 5, and a protrusion 9 for whispering 10, whispering 11.

In the trigger 4, the switch 12 for selecting a sequence of shots is assembled.

The inertial disconnector 13 "ball-10 peacefully mounted in the shank of the block 1, has an emphasis 14 for interaction with the link 15 and the tooth 16 for contact with the selector 7. The link 15 is mounted on the axis 17 and has a kinematic connection with the locking plate and hvstrovik 15 ( not shown).

The mechanism works as follows.

When the gun is opened, the shank, through the locking bar, rotates the link 15 ”which, acting on the stop '14 of the inertial disconnector 13, rotates it clockwise. In this case, the tooth 16, acting on the selector 25 7, installs it on the tooth 6 of the latch 5. Switch 12 set a certain sequence of shots. When you press the trigger 4, the switch 12, raising one of the whispers 11, disengages it from the trigger (not shown), which fires from the first barrel.

At the same time, the selector 7 rises 35 together with the trigger 4, disengaging from the tooth '6 of the retainer 5.

The gun moves back, the finger begins to lag behind the trigger. A shot from the second barrel is not possible, since there is no kinematic connection with the second sear. At the time of the shot, under the action of inertia forces, the inertial disconnector 13, rotating clockwise, forcibly puts the selector 7 with its protrusion 8 over the tooth 6 of the latch 5. After hitting the shoulder, the arrow finger runs onto the trigger 4, releasing the selector 7 from engagement with a latch 5. Moreover, since there is still no kinematic connection of the trigger 4 with the second sear

11, the shot does not occur. This is achieved by reducing the possibility of a double shot, regardless of the duration of the cycle of the inertial disconnector.

When the trigger 4 moves under the influence of its spring to the initial position, the selector 7 with its protrusion 9 rises under the protrusions 10 of both whispers 11. To produce the second shot, you must again press the trigger 4. At the same time, the selector 7 raises both whispers 11, firing from the second barrel , and since both whispers rise, the descent force becomes greater than during the first shot due to overcoming the additional spring force of the second whisper.

The proposed trigger mechanism will increase the reliability of preventing a double shot and, in the normal course of the trigger, provides a higher trigger force during the second shot compared to the first, i.e. improves its performanceί

(5) TWIN-TREATED MECHANISM The invention relates to sporting and hunting weapons and is a trigger for a double-barreled rifle. Known trigger double-barreled shotgun containing one trigger, sear, disconnector with a spring and switch sequence of shots tl. A disadvantage of the known mechanism is the large value of the stroke of the trigger when fired from the second barrel, which adversely affects the accuracy of shooting. Also known is a trigger for a double-barreled shotgun containing a trigger, sears, triggers, an inertial disconnector and a spring-loaded selector with a lock fixed to it with a beveled tooth 21. The disadvantage of this device is that it does not provide increased triggering force and slow trigger. hooks at the second CUTTER. boom, which degrades the performance of the guns. The purpose of the invention is to increase the operating characteristics of the mechanism. The goal is achieved by the fact that in the trigger mechanism containing the trigger, the sear, the trigger, the inertial uncoupler, the spring-loaded selector and the retainer with the tooth, the inertial uncoupler is made in the form of a freely swinging lever with the tooth, interacting with the selector, the retainer is installed on the same axis with the trigger hook, and on the selector upper and lower ledges are formed, interacting respectively with the tooth of the fixer and with the sear. The drawing shows the trigger of a double-barreled gun, a general view. The trigger mechanism is assembled in block 1, on the base 2, on the axis 3 of which the trigger is pivotally mounted and the spring-loaded latch 5/3 9 with the tooth 6. In the trigger k the spring-loaded selector 7 has a protrusion 8 that interacts with the tooth 6 of the latch 5 , and the protrusion 9 for interacting with the protrusions 10 whispered 11. In the trigger hook k is assembled the switch 12 of the selection sequence of shots. The inertial uncoupler 13 is hinged in the shank of the pad 1, has an abutment 1 t for engaging with the slide 15 and a tooth 16 for contacting with the selector 7 o The curtain 15 is mounted on the axis 17 and has a kinematic connection with the locking bar and the chopper (not shown). The mechanism works as follows. When opening the gun, the shank through the locking bar turns the slide 15 which, acting on the stop of the inertial disconnector 13, turns it clockwise. In this case, the tooth 16, acting on the selector 7, places it on the tooth 6 of the latch 5. Switch 12 sets a specific sequence of shots. When the trigger k is pressed, the switch 12, raising one of the whisper 11, disengages it from the hook with the trigger (not shown), which shoots from the first barrel. At the same time, the selector 7 rises along with the trigger H, the release from engagement with the tooth 6 of the latch 5. The gun moves backward, the finger begins to lag behind the trigger. A shot from the second barrel is not possible since there is no kinematic connection with the second sear. At the moment of the shot, under the action of inertial forces, the inertial uncoupler 13, rotating clockwise, forces the selector 7 with its protrusion 8 to the tooth 6 of the latch 5. After hitting the shoulder, the arrow finger runs onto the release hook t, releasing the selector 7 from meshing with the latch 5. In this case, since there is still no kinematic connection of the trigger k with the second sear 84 11, the shot does not occur. With this, reduction of the possibility of double shot is achieved, regardless of the duration of the inertial separation cycle. When the trigger A moves under the action of its spring to the initial position, the selector 7 with its protrusion 9 rises under the projections 10 of both whispered 11. For the second shot it is necessary to press the trigger again hook k. In this case, the selector 7 raises both of the whispers 11, making a shot from the second barrel, and since both of the whispers rise, the descent force becomes greater than during the first shot by overcoming the additional effort of the spring of the second whisper. The proposed trigger mechanism increases the reliability of preventing double shot and provides, during the normal course of the trigger, a higher trigger force on the second shot compared to the first, t, e. improves its performance; Formula of the invention: The trigger of a double-barreled shotgun containing the trigger, sears, triggers, inertial splitting, spring-loaded selector and lock with a tooth, characterized in that, in order to improve the operating characteristics of the mechanism, the inertial uncoupler is made free a lever with a tooth interacting with the selector, the lock is mounted on the same axis with the trigger, and the selector has upper and lower protrusions that interact with Respectively with claw tooth and with whispers.
