Description

The invention relates to weapons and can be used for quick multiple installation of auxiliary devices (silencer, optical sight, video sight, laser pointer, flashlight, butt, recoil compensator, collimator sight, bipod, weaver or dovetail trims) on a Makarov pistol (PM) and its analogues. Known mounts of laser target designators (LCC) of collimator sights, and a silencer, and recoil compensator, and other auxiliary devices on the PM, and its analogues:

a) LTSU, using a screw clamp for a bracket (Amba-PM ZAO "Kantegir", Saratov),

b) LCC, using a bracket mounted on the under-barrel part of the frame by drilling holes in it, threading them and installing the “Dovetail” lath with screws according to patent RU 2141093 of the Izhevsk Mechanical Plant,

c) a collimator sight, using a bracket mounted on the upper part of the arrester screwed onto the PM barrel with thread (http://www.makarov.com/graphics/scopemount_new.jpg),

g) LCC, by changing the design of the PM frame by casting the frame together with the LCC case (patent RU No. 2141093 C1, Izhevsk Mechanical Plant), by placing the LCC in the handle according to US Pat. US No. 5435091).

e) it is known that the silencer and recoil compensator are fastened to the PM by replacing the standard barrel with an elongated barrel with a thread at the end, screwing (http://www.makarov.com/makpics.html),

f) it is known that the tactical flashlight and the LCC are mounted on the Glock pistol by fixing to the frame on the Weaver built-in rail (Glock Autopistols 2006, vol. 12 No. 1) and the same mount of the collimator sight, flashlight on the Bul Cherokee pistol (Israel), as well removable butt to the bottom of the handle (http://world.guns.ru/handguns/hg206-r.htm).

The disadvantages of the known devices are:

- under item (a) - unreliability of fastening due to the mobility of the trigger guard and the need for adjustment after each removal and installation of the LCC on the PM;

- under item (b) - violation of the PM design when drilling a frame for installing the “Dovetail” bar, which is unacceptable according to the rules for using weapons;

- under item (c) - the impossibility of installing a collimator sight on a gun that does not have a thread at the end of the barrel;

- under item (d) - the impossibility of using the LCC with standard PM, since it is required that the LCC housing be cast together with the PM frame at the stage of its manufacture;

under item (e) - the impossibility of attaching the muffler by screwing onto the barrel of a standard PM due to the lack of a threaded part on the barrel of a standard PM;

- under item (e) - the impossibility of attaching a tactical flashlight and laser sight to the Weaver bar due to its absence on a standard PM; the inability to attach the butt to the PM handle due to the lack of appropriate fasteners on it.

In addition, for all the listed mounts there is no universality, i.e. the impossibility of installing various auxiliary devices on one bracket, due to the inability of most bracket designs to withstand large dynamic loads, as well as the reproducibility and speed of their fastening.

The closest in technical essence is the mounting bracket LTSU "Korsak-3" (http://www.belomo.by/rus/5_3_11raz.htm), made in the form of a frame with a slot, worn on the underbarrel end of the gun frame in front of the trigger guard and fixed on the side of the frame of the gun clamp with four screws.

The disadvantages of this device are: unreliable fastening with four screws on the side surface of the PM frame due to the lack of a base mounting point and the need to push the sharp ends of the screws into the metal of the frame, which spoils the appearance of the gun and its anti-corrosion coating. After removing the LTC with PM, re-alignment of the LCC is required. An additional tool is required to mount the bracket to the gun frame. It is possible to fix only one auxiliary device to the bracket - LCC. Inability to use a standard holster with a bracket mounted on the gun.

The objective of the invention is the creation of a universal bracket that allows fast, reproducible mounting of auxiliary devices (both one and several at the same time) on a standard PM and its analogs without changing the design of the gun.

1. The task is achieved in that the universal bracket for mounting auxiliary devices on a Makarov pistol and its analogues contains a frame with a slot made in the form of a two-shouldered lever mechanism having sliding planes interconnected by two supporting platforms, on one of which there are mounting T -shaped and guide grooves, threaded holes with screws for attaching auxiliary devices and a support screw, and on another support platform, made in the form of a segment located under scrap to sliding planes, in the center of which there is an adjusting screw, and having two protrusions, one of which has a threaded hole, in which there is a screw with a slider, at the end of which there is a recess, and the other is a recess coaxial with this screw, one of the sliding planes has an extension, at the end of which there is a hook of the butt plate of the pistol frame, pivotally connected to the extension by an axis; on the lateral side of the extension there is a rotary latch, with the possibility of rotation on the axis perpendicular to the sliding planes and having a protrusion, with a support pad for the finger, under which there is a protrusion-lock for fixing the butt, and the latch rests on one end of the butt plate of the gun frame, and the other at the end, it enters the hat of the rivet located on the lateral surface of the sliding plane, and on the lateral surfaces of the sliding planes there are threaded holes for fastening sockets, inside of which there are I have holes parallel to the sliding planes for attaching auxiliary devices.

The essence of the claimed invention lies in the fact that the bracket is made in the form of a slot with a slot into which the gun is inserted so that when screwing the fastening screw and clamping the axis of the trigger guard, four brackets appear on the bracket on the frame of the gun - on two supporting platforms, on the axis of the trigger guard and on the swinging hook on the rear of the gun frame.

The bracket frame is made in the form of a two-shouldered lever mechanism with a rotation axis coinciding with the axis of the trigger guard of the gun, and when you try to rotate the sliding plane around this axis, the bracket frames abut against the bottom surface of the pistol shutter, excluding the displacement or rotation of the bracket relative to the pistol frame. The presence of a fixed fulcrum (axis of the trigger guard of the gun) contributes to the accuracy of restoring the position of the bracket during repeated removal and installation on the gun. The presence of only two clamping fasteners provides quick installation and removal of the bracket on the gun, without the use of additional tools. The design provides for incomplete disassembly of the gun without removing the bracket. The presence of adjusting screws on the bearing pads contributes to the accuracy of the bracket installation and the restriction of the pistol trigger stroke, which increases the accuracy of shooting. The bracket allows you to install various auxiliary devices on three mounting planes at the same time.

The bracket has a shape that fits the plane of the gun frame.

The inventive arm (1) (Figs. 1-4) comprises a frame (2) with a slot (3), into which a gun is inserted with the trigger pulled down. The frame is made in the form of a two-shouldered lever mechanism having sliding planes (4) and (5), on the surface of which the lower surface of the pistol shutter rests, with the possibility of sliding, interconnected by two supporting platforms (6, 7), on one (6) of which has a T-groove (8) for attaching a silencer, LOC, recoil compensator, and threaded holes with screws (9) for attaching quick-detachable brackets for a lantern, LOC, or dovetail, Weawer trims, and also on the bottom of the supporting platform (6) there are guide grooves ( 10), parallel to the sliding planes (4, 5) and used to orient the silencer bracket, and on another supporting platform (7), made in the form of a segment with protrusions and located at an angle to the sliding planes (4; 5), coinciding with the handle surface behind the trigger, there is an axis (aa ') of rotation of the lever mechanism, coinciding with the axis of attachment of the trigger guard of the gun (with the bracket mounted on the gun), and formed when the axis of the trigger guard of the gun is clamped between the screw (11) and the protrusion (12) reference area (7). On the inner surface of the protrusion (12) there is a recess (13) located on the axis (a-a '), into which the end of the axis of attachment of the trigger guard protruding beyond the limits of the pistol frame, the second end of which is clamped by a screw (11) with a slider, at the end which also has a recess (14). The screw (11) is located in the threaded hole of the protrusion (12 ') of the support platform (7). When the screw (11) is clamped, the ends of the axis of the bracket of the gun are centered in the recesses (14) of the end of the screw (11) and (13) of the protrusion (12) and it coincides with (aa '), ensuring the accuracy of the bracket on the gun. The sliding plane (4) is limited by the dimensions of the supporting platforms (6, 7), and the sliding plane (5) from the side of the platform (7) has an extension (15) that forms the second shoulder of the lever mechanism, at the end of which there is a hook of the butt plate (16) of the gun frame pivotally connected to the extension (15) by an axis (17). Also on this extension on the side surface is a rotary latch (18), rotating on the axis (19) perpendicular to the slip planes (4, 5). On the side sliding surfaces (4, 5) between the supporting platforms (6, 7) there are threaded holes (20) for mounting removable sockets (21, 22), designed for mounting a video sight, a collimator sight, a butt, inside which there are holes (23) parallel to the slip planes (4, 5).

On the inside of the segment of the support platform (7), behind the trigger, in the hole (24) there is an adjustment screw (25), restricting the stroke of the trigger of the gun from “falling through” after the trigger is released.

On the rotary latch (18) there is a protrusion (26), in a horizontal position towering above the sliding surface (5) of the extension (15). The latch (18) has a plane (27), bent at 90 °, which serves as a support platform for the finger when it rotates around its axis (19). On the side surface of the latch (18) there is a protrusion-lock (28) for fixing the butt. There is a stop (29) on the lateral surface of the butt plate (16) of the butt plate of the gun, in which the end of the latch (18) abuts in a horizontal position. The second end of the latch (18) in this case extends beyond the rivet head (30), which is located on the lateral surface of the sliding plane (5). On the platform (6) there is a threaded hole in which the support screw (31) is located.

The device operates as follows:

The rotary latch (18) is translated into a position perpendicular to the elongation (15), releasing the hook (16) of the back plate of the pistol frame, which is able to rotate on the axis (17). The screw (11) is unscrewed until its end coincides with the inner surface of the protrusion (12 ').

On the PM pistol, the trigger guard is pulled so that its end extends beyond the frame and, into the resulting gap, pass the support platform (7). Circle the trigger with the support pad (7) at the back until the outer surface of its segment and the protrusions coincide with the surface of the handle behind the trigger and charge the bracket to the frame of the gun so that the end surface of the screw (11) is above the end of the axis of the trigger guard of the gun. The second end of the axis of the trigger guard, while falling into the recess (13) of the protrusion (12). Since the ends of the axis of the PM trigger guard protrude beyond the gun frame and have conical or rounded ends, when clamping it between the recess (13) of the protrusion (12) and the recess (14) in the end of the screw (11), the axis is firmly fixed in a certain position, providing accuracy of installation of an arm on the gun at repeated installation. In this case, the sliding planes (4, 5) abut against the lower surface of the pistol shutter with the possibility of sliding the bolt along them, and the extension (15) prevents the bracket from deflecting downward, and the planes (4, 5) upward with respect to the axis of rotation a-a '.

By turning the lock (18) to a horizontal position, the hook (16) is taken out from the back plate of the gun frame, achieving its hard stop in the back plate. The stop force is regulated by the degree of pressure on the support platform (27) of the lock (18). In this case, the end of the latch, located under the support platform (27), comes under the hat of the rivet (30) for additional fixation of this end. The second end rests against the stop (29) of the hook (16) and rigidly fixes the position of the hook on the extension (15) and on the back plate of the gun frame.

Using the support screw (31) from the bottom of the support platform (6), select the backlash of the pistol frame relative to the bracket so that the pistol slide freely slides along the sliding planes (4,5) and the bracket does not have a backlash on the frame.

The adjusting screw (25) limits the free movement of the trigger after the trigger is pulled to a minimum.

After these operations, the bracket is considered mounted on the gun. In subsequent removal-settings, adjustment of the screws (25) and (31) is not required, and all operations are reduced only to tightening the screw (11) and turning the lock (18). The installation time of the bracket on the gun is 10-15 seconds.

When installing the “Dovetail” (Fig. 12) and “Weaver” (Pikatinni) (11) strips on the bracket, fixing them in the threaded holes with screws (9), it becomes possible to quickly install the LCC, a flashlight, and other auxiliary devices on the gun having appropriate mounting brackets. Since the dimensions of the seating surfaces on the bracket are the same on the sides, two brackets (including different ones) can be simultaneously installed on the bracket, which allows two or three different devices to be fixed on them simultaneously. At the same time, the removability of additional devices is ensured by the design of the slats.

The muffler, LCC, recoil compensator, bipods are fixed directly to the bracket (1) without installing the straps (Fig.6-9; 15; 16) in the T-slot (8), with fixing screws. Tactical flashlight (Fig.6) and LCC (Fig.8) can also be mounted on the bracket (1) using additional quick-detachable brackets on the screws (9).

The butt (Fig. 14) on the bracket (1) is installed, when the rotary latch (18) is turned 90 degrees, by inserting the ends of the butt rods into the holes (23) of the removable sockets (21.22) until they stop. The stock in the sockets (21, 22) is fixed by turning the lock (18) to a horizontal position in which the protrusion-lock (28) enters the slot of the stock bar.

The video sight and collimator sight (Figure 10, 13) are also installed in removable sockets (21, 22) and are fixed by turning the lock (18) to a horizontal position.

When fired, the pistol slide moves along the slip planes (4, 5) and the upper extension surface (15). In this case, all the support points of the bracket (1) on the gun are saved and it does not change its position.

The bracket can be easily removed from the pistol, as with some additional devices - a silencer, a flashlight, an LCC, a recoil compensator, and without them, it does not interfere with incomplete disassembly of the pistol and placing it in a holster. The weight of the bracket with removable sockets installed on it is 100 g.
