Description

The invention relates to hand-held short-barreled firearms with automatic reloading, and in particular, to automatic revolvers with a cylindrical drum and a curved barrel (referred to by the authors as “curved-shaped revolvers”), mainly of police and civilian types.

Most revolvers are equipped with a frame (case), a straight barrel installed immediately behind it by a classical (cylindrical) drum, the axis of rotation and the axis of the chambers of which are parallel to the axis of the barrel, then the rotation and fixing mechanism of the drum (MPFB) and the trigger mechanism (trigger) , then - the handle, while part of the trigger (the mainspring) can be placed in the cavity of the handle [1. Zhuk A.B. Revolvers and pistols. - M.: Military Publishing House "Lokid", 1992. - 431 p.: Ill. - S. 30-218].

With all the advantages of revolvers, this arrangement leads to the fact that the proportion of the barrel length in the overall dimension of the revolver is small in length (which limits the power of the shot), the high level of the barrel location above the handle determines the imbalance of the weapon (the overturning moment when giving back with the barrel tossing), and the bulging one the sides in the middle part of the frame (case) the drum makes it difficult to carry and remove such weapons.

So, along with the problem of increasing the compactness of short-barreled hand weapons, the problem of the aforementioned shot power continues to take place. One of the ways to increase it is to lengthen the bore. But this conceptually contradicts the very concept of “short-barreled weapons” and is in clear antagonism with the desire for compactness.

Nevertheless, a whole variety of revolvers has recently appeared, characterized by a barrel bent along the radius in the longitudinal vertical plane, partially entering the handle cavity, where the drum is located. Such weapons were developed by the authors of the claimed technical solution and patented in the Russian Federation [2. RU 2620125 C1, F41C 3/14, F41A 21/16, 05/23/2017, Bull. No. 15; 3. RU 2635938 C1, F41C 3/14, F41A 21/16, 11/17/2017, Bull. Number 32; 4. RU 2611444 C1, F41F 9/27, 02.22.2017, Bull. No. 6; 5. RU 2650300 C1, F41C 3/14, 04/11/2018, Bull. No. 11; 6. RU 2630042 C1, F41C 3/14, 09/05/2017, Bull. Number 25; and etc.]

All curvilinear concepts are not automated.

In the version of "flat revolvers" (also proposed and previously patented by the authors) there is an automatic concept of revolver type weapons [7. RU 2630019 C1, F41C 3/14, 09/05/2017, Bull. No. 25].

In it, the barrel along its entire length (from the muzzle to the hemp) is made rectilinear in all longitudinal planes, and the drum is made of a disk, with a chamber orientation sealed chordally and is located completely in the space between the shaft stump on the one hand and the handle with the trigger on the other , and is made reclining to the side with the possibility of access to its rear end and the bottoms of cartridges / cartridges in the chambers. This constructively removes it from the revolver considered here with a “classical” cylindrical drum and an “exotic” curved barrel and, accordingly, does not allow to use its automation circuit in a construction with a cylindrical drum.

Closest to the claimed invention in terms of purpose and a set of design features (prototype) is a crank revolver with a cylindrical drum, comprising a body with a hollow handle and a lid, and a barrel mounted therein with a straight front section from the muzzle, oriented horizontally, and rear bent in radius section to the bullet entrance (short straight section from the hemp of the trunk), oriented back and down and entering the cavity of the handle, a cylindrical drum with an axis of rotation and several through cameras spaced apart from each other with the same angular pitch, the axes of which are parallel to the axis of rotation of the drum, with the possibility of manually equipping them with cartridges and manually extracting spent cartridges, a locking device, a mechanism for turning and fixing the drum in combat positions with any camcorder aligned to the bullet entrance the bore of the barrel and the micro-clearance between the front end of the drum and the surface of the hemp of the barrel, the trigger mechanism with a spring-loaded trigger, and a safety device, with p most of the memory location of said revolver components including drum, at the bottom of the cavity of the handle [2. RU 2620125 C1, F41C 3/14, F41A 21/16, 05/23/2017, Bull. No. 15].

In it, the drum has only one degree of freedom - a stepwise angular rotation.

However, with all its advantages, such a weapon has still not enough tactical, technical, operational characteristics, inferior to pistols in terms of automation (see above on automation of revolvers). It should also be noted that the spectrum of variety of models of revolvers is narrowed taking into account the factor of product attractiveness (the latter is applied to export supplies and to the market of civilian, in particular traumatic, weapons).

The task (problem), the solution (elimination) of which the claimed invention is directed, is to automate the revolver with simple technical means, while expanding the functionality of the drum, and therefore to improve its tactical and operational characteristics as a result.

It also seems appropriate to expand the variety of models of revolvers taking into account the factor of commodity attractiveness (the latter - in relation to export supplies and to the market of civilian, in particular traumatic, weapons).

The solution of the complex task (elimination of the problem) is achieved by the fact that in an automatic curvilinear revolver with a cylindrical drum containing a body with a hollow handle and a lid, and a barrel installed in it with a straight front section from the muzzle, oriented horizontally, and a rear section curved along the radius to the pool entrance, oriented back and down and entering the handle cavity, a cylindrical drum with the possibility of rotation and several spaced apart from each other with the same angles step through cameras, the axes of which are parallel to the axis of rotation of the drum, with the possibility of manually equipping them with cartridges and manually extracting spent cartridges, a locking device, a mechanism for turning and fixing the drum in combat positions, aligning any of the chambers with the pool entrance of the barrel channel and a micro-gap between the front end of the drum and the stump of the barrel, trigger mechanism with a spring-loaded trigger, and a safety device, with the location of most of the mentioned components of the revolver, including the bar aban, in the lower part of the cavity of the handle, according to the claimed invention, the reloading device is automatic due to the recoil energy, while the drum is mounted with the possibility of axial reciprocating movement, a pallet spring loaded by the return spring of the drum is rigidly attached to the rear end of the drum with the possibility of operational disassembly / installation when equipping and fixing cartridges in the chambers from falling out, it is installed sequentially behind the pallet, also with the possibility of axial reciprocating movements, a spring-loaded cylindrical firing pin with a bounce spring in the blind hole and the striker opposite the war chamber, from the trigger is laid under the curved section of the barrel and through the hollow axes of the drum and the pallet to the firing pin, the horizontal-leaf spring of the firing mechanism drive with a beveled pusher of the firing pin at the end for interactions in its extreme working position with a retarded beveled sear stationary relative to the body, a drum, lower links of the trigger mechanism and a recharge device Niya covered by a common glass, removably integrated into the cavity of the handle, fixed by a stopper with a lock and which is a guiding element for the drum, and on the outer surface of the drum there are curved or inclined blind grooves for spring sliders in the longitudinal grooves in the glass, connected with the pallet, with the possibility of rotation of the drum one angular step with full axial stroke of the pallet.

The solution of this problem is also achieved due to an additional set of design features (with the main set of features formulated above), namely: a drum closer is installed parallel to the glass with a manual control unit pulled outward from the back of the handle with freedom of reciprocating movement along the axis of the glass, with the possibility duplicating, in relation to automation, manual rotation of the drum by a fixed angular pitch in case of misfire.

Among the known devices and methods, no such combination of essential features would coincide with the declared one. At the same time, it is due to the latter that a new technical result is achieved in accordance with the task (problem being solved).

An automatic crank revolver with a cylindrical drum comprises a housing 1 with a hollow handle and a cover 21. In the housing 1, a barrel 2 is installed with a straight front section from the muzzle section, oriented horizontally, and a rear (taking into account the rectilinear bullet entry at the hemp - middle) section to the bullet entrance, oriented back and down and entering the handle cavity. There is a cylindrical drum 4 with the possibility of rotation and several through cameras spaced apart from each other with the same angular pitch, the axes of which are parallel to the axis of rotation of the drum 4, with the possibility of manually equipping them with cartridges 5 and manual extraction of spent cartridges. A locking device, a mechanism for turning and fixing the drum 4 in combat positions with the alignment of any of the chambers to the pool entrance of the barrel 2 and the micro-clearance between the front end of the drum 4 and the hemp of the barrel 2, trigger mechanism (trigger) with a spring-loaded trigger 8, and a safety trigger are provided device. Most of the mentioned components of the revolver, including drum 4, are located in the lower part of the handle cavity.

The reloading device is automatic due to the recoil energy, while the drum 4 is mounted with the possibility of axial reciprocating movement (centered on its outer cylindrical surface). To the rear end of the drum 4 is rigidly attached spring-loaded return spring 11 of the drum 4, the pallet 7 of the drum 4 with the possibility of rapid dismantling / installation with equipment and fixing cartridges 5 in the chambers from falling out. Sequentially behind the pallet 7 is installed, also with the possibility of axial reciprocating movement, a spring-loaded (mainspring 12) cylindrical drummer 6 with a breakaway spring 25 in the blind hole and the striker opposite the combat chamber. From the trigger 8, it is laid under the bent portion of the barrel 2 and through the hollow axis of the drum 4 and the pallet 7 to the hammer 6 to the horizontal-leaf spring 9 of the trigger actuator with a pusher 13 made with an end stepped cut for stop in the hammer 6 and a bevel for interaction in the extreme working its position with a response beveled sear 14, stationary relative to the housing 1.

The drum 4, the lower links 6, 11-14 of the trigger and the reloading device are covered by a common glass 3 (see Fig. 3), removably integrated into the cavity of the handle. In this case, the cup 3 is fixed (see Fig. 1) by the stopper 20 (with the engine 19 and the lock 17 (on the screw 18) and which is the guiding element for the drum 4. On the outer surface of the drum 4 (which it is paired with the cup 3) are curved or inclined blind grooves (see Fig. 4) for spring-loaded (spring-loaded) sliders 24 in the longitudinal grooves 23 in the cup 3 (see Fig. 3), with the possibility of turning the drum 4 by one angular step with full axial stroke of the pallet 6.

In parallel with the cup 3, a spring closer 15 (see FIG. 3) of the drum 4 can be installed (and it is recommended to install) of the drum 4 with a manual control unit pulled outward from the back of the handle with freedom of reciprocating movement along the axis of the cup, with the possibility of duplicating, automation, manual rotation of the drum 4 (through its longitudinal movement) by a fixed angular pitch in case of misfire.

There may be some increase in height dimensions when switching to 9 Parabellum cartridges, at which the drum length will increase by 5 mm. Here we should return to the development of "curved" barrels under the cartridge 7.62 TT, carried out in the USSR in the late 40s, but they can be considered reasonable for other cartridges.

The described examples (specific particular embodiments) of the design do not exclude other possible variants of the device within the scope of the claimed combination of essential structural features (see the claims).

It is possible to introduce a flag, button or other “special” (that is, in addition to the taut self-resetting characteristic of revolvers as a safety device) fuse (not shown).

The inventive device works (use a revolver) as follows.

When you press the trigger 8, the one, compressing the trigger spring 10 of the trigger, through the leaf spring 9 of the trigger of the trigger sends the impact on the plunger 13. He, moving back and down, takes the hammer 6 back, compressing the war spring 12. With further displacement, the oblique cut of the pusher 13 enters into interaction with the reciprocal oblique slice of the sear 14 and, bending the spring 9 of the USM drive in one direction (side-to-front), and the hammer 6 to the other (side-back, due to the installation of the hammer 6 with side clearance, as well as some lateral compliance springs 12 in radial directions lation, its stepped cut-out engages with drummer 6. The latter, under the action of the mainspring 12, rushes towards the drum 4 - forward and, overcoming the resistance of the break-off spring 25, enters the hole of the pallet 7 and strikes the cartridge 5. The shot is fired.

After the shot, the break-off spring 25 leads the drummer 6 out of the hole of the pallet 7 and, at the same time, under the action of recoil, the pallet 7 starts to move backward, dragging the drum 4 and compressing the return spring 11 of the drum 4 (of course, the pallet 7, which is rigidly connected to the drum 4) and the mainspring 12. At the same time, spring-loaded (spring-loaded) sliders 23 included in blind grooves on the surface of the drum 4 (see Figs. 3, 4), while remaining stationary, ensure its rotation by a given angle (angular step) during all of his "rollback" (transformation Yelnia drum 4 into rotational movement is possible due to excess torque recoil forces on the drum 4 above the retaining moment resistance forces rotation of the drum 4). That is, the drum 4 additionally performs the functions of a shutter moving under the action of recoil when fired.

When you release the trigger arrow 8 with your finger, the trigger elements 8, 9, 4, 7, 6 trigger the springs 10, 11, 12 and move forward (to the initial axial position), dragging the trigger spring 9, which pulls the pusher 13. , in turn, due to the flexibility of the spring 9 of the trigger actuator, a stepped cut catches the surface of the hammer 6 (i.e., returns to its original state).

In the case of misfire, the transfer of the drum 4 to the next angular step is carried out manually, by pressing the spring closer 15 by pressing the thumb and forefinger (see Fig. 3): the reciprocating device is informed of the working body parallel to the axis of rotation of the drum 4.

To reload the revolver (change the “shot” drum 4 to the equipped spare one), rotate the lock 17 of the cup 3 around the axis of the elements 16, 18. In this case, the protrusion of the lock 17 comes out of the spring hole 16 of the lock 24 of the lock 17, the cup 3 is shifted in the handle axially outward to a distance limited by the stopper 20. After that, replace the drum 4 with another (main option) with the combination of grooves and sliders 23.

To recharge the same drum 4, the pallet 7 is disconnected (unscrewed) from the drum 4, the cartridges 5 are shaken out or pushed out 5 and cartridges 5 are inserted into the chambers, after which the pallet 7 is again attached (screwed) to the rear end of the drum 4, making sure that the holes in the pan 7 coincided with the capsules of the cartridges 5.

To remove the cup 3 from the cavity of the handle, the stopper 19 engine connected to the stopper 19 is fed forward, while the stopper spike 19 comes out of the groove of the cup 3, and the latter is completely pulled out.

Using the invention allows to increase the combat (tactical, technical, operational) characteristics of the weapon: to automate the revolver, while expanding the functionality of the drum due to the additional function of the movable shutter, and also to expand the variety of models of revolvers, taking into account the factor of commodity attractiveness (the latter applies to export deliveries and to the market of civilian, in particular traumatic, weapons).

The claimed device is unique: the applicants are not aware of any other designs or designs of automatic turret revolvers.

The revolver is recommended for reasonably limited production and use, in order to expand the range of hand-held short-barreled firearms.
