SU591031A1 - Double-barreled gun trigger mechanism - Google Patents

Description

The invention relates to triggers for double-barreled shotguns with one selector trigger, equipped with a disconnector, which serves to prevent a double shot.

Known trigger mechanism, with an inertial disconnector, which is a massive body mounted on an axis offset from the center of gravity. At the time of the shot due to recoil, the disconnector, under the action of inertia, rotates around its axis, blocking the trigger and ·· thereby preventing a double shot.

However, the disconnector of such a mechanism at the time of recoil strikes. It stops and spontaneously bounces, as a result of which premature unlocking is possible, and consequently, an arbitrary shot from the second barrel. .

Also known is the trigger of a double-barreled gun with a spring-loaded inertial disconnector, serving at the same time for the production of the second shot. At the moment of the first shot as a result of the recoil, the disconnector is pressed against the switch, then, during the release, under the influence of inertia, it is deflected backward, and at the next moment it is installed under the second sear under the action of the spring. Thus, the disconnector is installed under the second sear with a delay, in time, due to which there is no double shot.

However, such a design of the mechanism is difficult to manufacture and to debug.

The purpose of the invention is to increase the reliability of preventing double shots and simplifying the design.

This is achieved by the fact that the trigger is equipped with a tooth that interacts with a profile recess made on the disconnector and provides preliminary blocking of the trigger with the disconnector.

The drawing shows the proposed trigger before the shot, General view.

A spring-loaded trigger 2 is placed in the groove of the base 1 with the possibility of rotation around the axis 3. The disconnector 4 is mounted on the axis 5 so that its center of gravity is located above the axis of rotation. The disconnector is spring-loaded 6. The selector 7, mounted in the trigger, alternately interacts with the sear 8 holding. at the cocking of the trigger 9. The construction of the whispers and the trigger is the same for both barrels. The tooth 10 of the trigger is placed in the profile recess 11 of the uncoupler, having a tooth 12 and a surface 13 interacting with the surfaces 14 and 15 of the trigger.

To fire a shot, press the trigger 2, turning it about the axis 3 counterclockwise (according to the drawing), while the selector 7 turns the sear 8 of the barrel from which the first shot should be fired. At the same time, the tooth 10 of the trigger 2, located in the profile recess 11. of the disconnector 4, rotates it about the axis 5 counterclockwise, and the tooth 12 of the disconnector 4 becomes below the surface 14 of the trigger 2, blocking the latter in the upper position. At the moment of the shot, the gun due to recoil is fed back, while the uncoupling 4, under the influence of inertia, tends to continue to move counterclockwise and is pressed by the surface 13 to the surface 15 of the trigger 2. At the same time, the trigger itself, under the action of its spring and inertia, returns to the initial position (clockwise), but, pressing its surface 14 to the tooth 12 of the disconnector, cannot fall down. At the moment of counter-release, the disconnector 4 under the action of the spring 6 starts to rotate clockwise oh arrow. The trigger remains in the upper position until the tooth 12 of the uncoupler completely leaves the zone of interaction with the surface 14 of the trigger, which means unlocking the latter. After that, the trigger descends to its original position, and the selector rises under the second sear, and the gun is ready to fire from the second barrel. This embodiment of the trigger mechanism ensures that the disconnector is forcedly set to the trigger locking position by the trigger itself, holding it at the moment of recoil in this position by inertia forces, and at the moment of counter recoil by the interaction of the disconnector tooth with the trigger. Therefore, the trigger takes its initial position with a time delay sufficient to prevent an accidental shot from the second barrel.

A device made in this way is reliable and easy to manufacture and debug.

(54) LAUNCH MECHANISM OF THE DOUBLE GUN 35 The drawing shows the proposed trigger mechanism before the shot, general view. In the groove of the base 1, a spring-loaded trigger 2 is placed so as to rotate around axis 3. Uncover the 4 mounted on axis 5 in such a way that its center of gravity lies above the axis of rotation. The uncoupler is spring-loaded spring 6. The selector 7, installed in the trigger, alternately interacts with the sear 8, holding the cocks 9 on the cocking squad 9. The design of the sear and the cocks is the same for both trunks. The trigger tooth 10 is located in the profile recess 1 of the disconnector, which has tooth 12 and surface 13, interacting with the surfaces 14 and 15 of the trigger. To carry out a shot, they press the trigger hook 2, turning it about the axis 3 counterclockwise (according to the drawing), while the selector 7 turns the sear 8 of the barrel from which the first shot is to be fired. At the same time, the tooth 10 of the trigger 2, located in the profile recess 11. the uncoupler 4, rotates it about the clockwise axis 5 and the tooth 12 of the uncoupler 4 becomes under the surface 14 of the trigger 2, blocking the latter in the upper position. At the moment of firing, the shotgun is fed back due to recoil, while the uncoupler 4 under the influence of inertia forces tends to continue to move counterclockwise and presses surface 13 to the surface 15 of the trigger 2. At the same time, the trigger itself, under the action of its spring and inertial force, tends to return to its original position (one arrow at a time), but, pressing its surface 14 to the tooth 12 of the uncoupler, cannot descend, At the moment of counter-return f) The guard 4 under the action of the spring b begins to rotate clockwise. The trigger remains in the upper position until the tooth 12 is separated. The whole l will not leave the zone of interaction with the trigger surface 14, which means unlocking the latter. After that, the trigger is lowered to its original position, and the selector gets up under the second chipper, and the gun is ready to shoot from the second barrel. This embodiment of the trigger mechanism provides a forced installation of the disconnector into the position of blocking the trigger by the trigger itself, holding the inserter at the moment of return in this position, and at the moment of counter-return by the interaction of the disconnector tooth with the trigger. Consequently, the trigger takes its initial position with a time delay sufficient to prevent an accidental shot from the second barrel. The device executed in such a way is reliable and simply in - production and in debugging. Claims The trigger of a double-barreled shotgun containing a trigger with a selector, whispered, triggers and a spring-loaded inertial uncoupler, characterized in that, in order to increase the reliability of preventing double shot and simplify the design, the trigger has a tooth, interconnecting a squad and a frame. on the disconnector.
