Description

Technical field

The invention relates to a device for cocking the trigger mechanism of small arms according to the restrictive part of paragraph 1 of the claims.

State of the art

Such a cocking mechanism is known from patent document DE 4223498 C2. In this cocking mechanism, the cocking handle (slider), made with the possibility of movement in the receiver between the rear unzipped position and the front cocked position, is connected with the cocking lever, made in the form of a pusher, for cocking or unloading the shock spring connected to the hammer. The cocking handle has a rear lock for engaging with a stopper rigidly mounted in the receiver to hold the cocking lever in the front cocked position. The rear end of the cocking handle is made with the possibility of lifting it outward in the front cocked position by approximately the depth of the stopper from the receiver, so that in the cocked position, the lock provided in the cocking handle latches into the stopper by moving the cocking handle forward and is held by the pressure of the shock spring. When you press on the rear end of the cocking handle, it is easy and convenient to unlock it.

The patent documents DE 19749290 C2 and DE 10118046 A1 also describe trigger mechanisms to prevent a second shot.

Disclosure of invention

The objective of the invention is the creation of a cocking mechanism of the aforementioned type, which provides independent from external influences automatic return of the cocking lever after the rebound of the hammer.

This problem is solved by the cocking mechanism of the trigger mechanism with the features of paragraph 1 of the claims. Suitable improvement options and preferred embodiments of the invention are the subject of the dependent claims.

In the cocking device of the firing trigger mechanism of small arms according to the invention, a platoon slider adapted to move between an unarmed position and a cocked position is affected by a return spring, by means of which a platoon slider automatically returns to a non-cocked position after the striker bounces. The return of the platoon slider does not have to be done manually, and it does not depend on external influences, for example, on the recoil force when firing. Even with light loads or during misfires, the platoon slider automatically returns, so that it is possible to produce a subsequent cocking and a new shot faster.

In a suitable embodiment, the return spring is located on the platoon slide in the direction of its movement. In this case, the return spring exerts a force on the platoon slider acting directly in the direction of its movement, as a result of which the platoon slider automatically returns to the unarmed position when unloading the shock spring caused by the firing of a shot.

In a particularly preferred embodiment, the stopper associated with the latch on the cock slider is located at the upper end of the backward inclined beveled platform. When the shock spring is unloaded after firing and the platoon slider is essentially only exposed to the backward spring force, the slider part of the platoon slider has the ability to slide its rear end along the beveled platform. As a result of this, a simple and reliable separation of the fixed holding position of the slider and its movement into the rear uninvolved position is achieved.

In another preferred embodiment, the stopper is located in a removable insert mounted in the receiver. If damage or wear is possible, this insert is easy to replace.

The return spring is preferably placed in tension between the lateral protrusion of the lower part of the cocking handle and the holding pin inserted into the receiver, and in the next preferred embodiment, is carried out on a stem extending in the direction of movement of the cocking slide.

The implementation of the invention

The single-shot trigger mechanism of the double-barreled shotgun shown in Fig. 1 includes a hammer 2 located in the receiver 1 with the possibility of movement on the lower body part 1a (the lock plate), for influencing the two strikers 3a and 3b. The shock spring 4 and the corresponding platoon 5 are located in the hammer 2. To compress the shock spring 4, the platoon 5 is moved by the platoon slider 6 by means of the platoon lever 7 from the rear unstressed position shown in Fig. 1 to the forward stressed position shown in Fig. 2.

As follows from figure 1, the firing pin 2 corresponds to two fuses 8, rotated between the locked and unlocked positions, and the trigger rod interacting with each of them 9. Both fuses 8, located next to each other, are coupled with the receiver 1 with the possibility of rotation around the first transverse pin 10 and have upper locking latches 11 to hold the hammer 2 in the rear locked position. Using the springs not shown, the fuses 8 are loaded so that their locking latches 11 are fed up. Each of the trigger rods 9 is located in the receiver 1 in the form of a two-shouldered lever with the possibility of rotation around the second transverse pin 12, and on the lower side of the rear shoulder of the lever, which is fed down by the corresponding pressure spring 13, has a groove 14 for receiving the pin 15 located on the lower the end of the corresponding fuse 8. The pressure springs 13 are in a tense position between the receiver 1 and the front shoulders of the trigger rods 9. The grooves 14 and pins 15 are adjusted to each other so that when lifting the rear shoulders with USKOVA rods 9 pins 15 are disengaged from slots 14 trigger rods 9, so that the fuses 8 are released.

The impact on the trigger rods 9 to release the fuses 8 is made using two intermediate levers 16 located in the main body 17 parallel to each other with the possibility of rotation around a common transverse axis 18. The intermediate levers 16 are made in the form of two-arm rotary levers, each of which is on the front, in the direction of the shot, the end of the front shoulder has a forward protruding nose 19 for engaging with a latch 20 at the lower end of the corresponding trigger rod 9. In addition, the intermediate levers 16 have outgoing 3 protrusions 21, one of which is engaged with the rear trigger 22, and the other with the front trigger 23. On its rear shoulders, the intermediate arms 16 have protruding protrusions 24, each of which is caught by a locking bolt 25, which can be moved to main body 17. Spring-tightened locking valves 25 pass in the main body 17 with the possibility of movement between the rear released position and the front locking position and are part of the fuse th device which is described in more detail in the German patent application DE 102008003722.

The main body 17 is located in the lower part of the receiver 1 with the possibility of movement in its longitudinal direction between the front unlocked position and the rear locked position, so that the intermediate levers 16 corresponding to the trigger levers 9 are able to move between the rear initial position shown in Fig. 1 and front trigger position. In the rear starting position, the front spouts 19 of both intermediate levers 16 are located at a distance from the latches 20 of the release levers 9. The protrusions 21 of the intermediate levers 16, extending downward from them, are also located at a distance from the triggers 22 and 23, so that this position does not exist no connection between the triggers 22 and 23.

When exposed to the slider 6, the main body 17 together with the intermediate levers 16 is pushed forward, so that they with their front spouts 19 grab the latches 20 of the trigger levers 9. At the same time, the intermediate arms 16 with their lower protrusions 21 mesh with the triggers 22 and 23, so that there is the possibility of pressing the trigger 22 or 23 to make the first shot. Depending on the choice of the trigger 22 or 23, the rear end of the corresponding trigger rod 9 is lifted by means of the intermediate lever 16 corresponding thereto, as a result of which either the right or left fuse 8 with a locking latch is released. The other fuse 8, by contrast, remains blocked, so that the firing pin can deviate to the right or left and actuate the strikers 3a or 3b. The front end of the hammer 2 has such a shape that when it deviates to the right, it activates the hammer 3a, and when deflected to the left - the hammer 3b.

The design and principle of operation of the single-shot trigger mechanism with a common striker 2 acting on both the strikers 3a and 3b is explained in the German patent application DE 102008003 722 of the same applicant. The applicant refers to this publication, and its content is also included in the content of this application.

Figure 2 in more detail presents a device for cocking the above trigger mechanism single action. The cocking device includes a slider 6, which contains a handle 28, movable in the longitudinal guide 26 on the upper side of the receiver 1, and the lower slide part 29 rigidly connected to it. As follows from the image in figure 3, on the lower side of the handle 28 two removable sleds 30.

The slider portion 29, shown in FIGS. 4 and 5 in side view and in horizontal projection, is rigidly connected to the handle 28 by means of an upwardly projecting finger 31 having an oval section. To connect with the handle 28 in the upper part of the finger 31 there is a transverse hole 32 provided with a thread. The slider portion 29 at the rear end has a longitudinal section 33 and beveled end pads 34 with a stopper 35 made in the form of a locking edge. At the rear end of the slider portion 29, there is also a transverse hole 36 for the transverse pin 37 shown in FIG. On the side of the slider part 29 in the region of the transverse hole 36, a laterally extending protrusion 38 with a longitudinal hole 39 is provided.

In the longitudinal hole 39 of the protrusion 38, extending to the side of the slider portion 29, the rear end of the stem 40 shown in FIG. 1 is movably mounted. The front end of the rod 40 is fixed in the mounting pin 41, inserted laterally into the receiver 1. The rod 40 is equipped with a pressure spring 42, by means of which the slider portion 29 is pressed back. As can be seen from figure 2, the transverse pin 37, located in the rear region of the slide part 29, enters the groove 43 of the upper part of the cocking lever 7, which is included in the longitudinal section 33 of the slide part 29. By means of the cross pin 44, the cocking lever 7, rotated relative to the transverse pin 45, is associated with a platoon 5 located in the striker 2, designed to tension the shock spring 4.

The finger 31 of the slide part 29 extends with the possibility of movement in the longitudinal hole 46 of the insert 47, shown separately in FIGS. 6 and 7. The insert 47 is fixed in the receiver 1 and contains on its lower side made with a slope back in the opposite direction to the end platform 34 the slider part 29, the beveled platform 48 with the stopper 49 related to the latch 35 of the slider part 29. The stopper 49 is located on the upper end of the beveled platform 48. As can be seen in figure 2, between the rear beveled end pads 34 of the slider part 29 and An acute angle α is formed by the front beveled pad 45 of the insert 47.

The above-described cocking device of the trigger mechanism operates as follows.

When pushing the handle 28 forward with the thumb, the slider portion 29 is pushed forward, and the shock spring 4 is pulled by the platoon 5 via the platoon lever 7. When the slider part 29 comes to the front cocked position shown in FIG. 2, the latch 35 in the slider part 29 is latched onto the corresponding stopper 49 in the insert 47, the slider part 29 together with the handle 28 slightly tilting forward. The latch 35 is held within the stopper 49 of the slider part 29 of the insert 47 by the shock spring 4, which by means of the cocking lever 7 produces an upward component of the force acting on the slider part 29.

When, by pressing one of the two triggers 22 or 23, the hammer 2 is released to act on the hammer 3a or 3b and as a result the first shot is fired, the shock spring 4 is almost completely weakened and exerts only a slight upward force on the slide part 29 through the cocking lever 7. After that, the slider part 29 by the force of the return spring 42, acting in the direction of movement of the slider part 29 back, along the inclined plane 48 is advanced from the stopper 49 and then moves back to the uninclosed position. When the slider part 29 moves backward, the hammer 2 also, under the action of the cocking lever 7, again moves to its rear starting position, locked by the locking latches 11 of the fuses 8. Then, by moving the handle 28 forward, the slider part 29 can be pushed forward again for a new cocking of the shock spring 4. After that, the slider part 29 is again fixed in the insert 37, and the trigger mechanism is ready for the production of the second shot.

This cocking mechanism is also easily transformed from a cocked state to an unclosed one. To do this, you only need to press the rear end of the handle 28. Thus, the latch 35 is pushed down from the stopper 49, and the slider portion 29 together with the cocking lever 7 is again squeezed into the uninclosed position shown in FIG. 1 under the action of the shock spring 4. In this position, the shock spring 4 is unloaded.
