Description

The invention relates to the field of small arms, and in particular to mechanisms for holding and retrieving a magazine, and is applicable, in particular, to a standard Makarov pistol and its analogs.

There is a known mechanism for holding and retrieving a magazine from a Makarov pistol using a push-button latch (passport of a Baikal-442 pistol, see www.baikalinc.ru), consisting of a button, a spring, a mainspring stopper and a magazine with a special spring cutout.

A similar design has a mechanism for fixing a small arms magazine (RF patent 2127410), which also consists of a latch button, a spring and a magazine with a spring cut-out.

In these designs, the magazine is removed by pressing the thumb holding the gun on the magazine latch button located on the side surface of the gun frame. In this case, the spring of the latch leaves the cutout of the magazine, and the magazine falls out or partially extends from the handle of the gun.

The disadvantages of this design are: the inapplicability of this device for Makarov pistols that do not have appropriate cutouts in the frame and stores; the lack of a fuse for pressing the latch button, which can lead to the ejection of the store if it is accidentally pressed; inconvenience of removing the magazine in the shutter position of the pistol “at shutter delay” when the magazine spring does not work and it does not extend out of the handle; inconvenience of removing the store when shooting with gloves in the winter due to the difficulty of pressing the latch button; incomplete removal of the magazine when turning the handle of the gun sideways or up.

There is a known mechanism for holding and removing a pistol magazine, consisting of a latch located on the lower end of the mainspring of the pistol and a projection of the magazine for which it engages (website htth: //talks.guns.ru/forummessage). The latch is located at the bottom of the end of the gun handle. To remove the magazine from the base of the handle, holding the gun by the handle with your right hand, use the left hand thumb to push the magazine latch back to failure, while simultaneously pulling the protruding part of the magazine cover with the left finger, and remove the magazine when the magazine latch releases the hook.

The disadvantages of this device, taken as a prototype, are: the inability to remove the store with one hand; the duration of the process of replacing an empty magazine with an equipped one; the inconvenience of changing the store when shooting with gloves in the winter; inconvenience of removing the magazine in the shutter position of the pistol "on the slide valve" when the magazine spring does not work.

The objective of the invention is the creation of an ejector store, allowing quick authorized removal of the store from the gun with one hand, including in the shutter position "on the shutter lag"; at any angle of the handle; in gloves (in winter conditions), and a pistol design that does not require rework (for example, PM or its analogues).

The task is achieved by the proposed ejector pistol magazine, including a latch located on the lower end of the mainspring of the pistol, and the protrusion of the magazine, for which it engages, and additionally containing a pin with a slot and a support screw, ejector spring, rod, made in the form of a frame with slots and protrusions with holes at one end thereof, and a support platform, located at an angle to the draft frame, with a fuse pivotally mounted on it with a bend at its other end, and a pin connecting the latch at the pistol with traction, through the slot of the pin and the holes of the protrusions of the traction.

On Fig depicts a check.

The device comprises a rod 1, a pin 2, an ejector spring 3 and a pin 4 mounted in the lower part of the handle of the frame 5 of the gun (Figs. 1-4).

Rod 1 (Figure 5) is made in the form of a thin-walled frame with a slot 6 for a magazine and a slot 7 for a pistol latch. The dimensions of the slot 7 are limited by protrusions 8 having holes 9 for securing the rod 1 to the gun using a check 4. On the other end of the rod 1 there is a sector platform 10, in the upper part of which a spring-loaded fuse 11 is pivotally mounted to prevent unauthorized ejection of the magazine. The fuse 11 is made in the form of a wire bracket, the ends of which form two rings 12 passing through the holes 13 in the upper part of the sector site 10, in which the fuse holder 11 is rotatable at an angle of 45-90 °. The fuse holder has a bend of 14 at a distance of 3-4 mm from the axis of the bracket rings at an angle of 60-80 °.

The internal dimensions of the thrust frame 1 correspond to the external dimensions of the end face of the handle of the gun and provide the possibility of displacement along the end of the handle.

The pin 2 (Fig.6) is made in the form of a cylinder having a diameter corresponding to the diameter of the hole of the latch 15 of the gun. The pin length is also limited by the size of the latch. On the side surface of the pin 2 there is a sector slot 16 for the checks 4 and a threaded hole 17 located at an angle of 25-35 ° relative to the plane of the slot 16. In this hole there is a support screw 18 with a hexagonal head, which serves to fix the position of the pin 2 in the hole of the latch fifteen.

The ejector spring 3 (Fig. 7) serves to ensure the ejection of the gun magazine at any position of the handle in space, including the shutter-off position, when the magazine spring does not allow the magazine to slide out of the handle of the gun.

The spring 3 is made of a wire in the form of a curly bracket, in the central part having protrusions 19, by which it is placed under the bolt of the gun 20, and rounded ends 21, inserted into the frame 5 of the gun in the shop window, so that the ends 21 abut against the side protrusions of the cover 22 magazines 23, when the magazine is inserted into the gun and locked with a latch 15.

Check 4 (Fig. 8) is made in the form of a wire rod having a bend 24 in the middle, which serves to fix it inside the slot 16 of pin 2. At one end of the check 4 there is a ring 25, which serves to facilitate removal of the check from the holes 9 of the rod 1 and the slot 16 pins 2.

The ejector store is installed on the gun (for example, Makarov) as follows:

a) remove the plastic handle of the gun, take out the magazine 23, and insert the pin 2 into the hole of the latch 15 so that the slope of the slot 16 is in the direction of the trigger guard of the gun. If the diameter of the hole of the latch 15 is larger than the diameter of the pin 2, the pin is removed from the hole of the latch 15, the support screw 18 is slightly unscrewed so that when the latch 15 is inserted into the hole, the pin fits tightly into it. In this case, a through hole is formed between the wall of the latch 15 and the slot 16 of the pin along the axis of the latch hole. (Check 4. is inserted into this hole during further assembly of the store ejector.);

b) insert the ejector spring 3 with the protrusions 19 under the protrusions of the valve 20 of the pistol coil spring, leading the rounded ends 21 into the window of the gun frame 5 so that they protrude slightly from the magazine window above the plane of the end face of the gun handle (Figure 1);

c) install the plastic handle on the gun;

g) on the end of the handle impose a rod 1 so (Figure 4) so that the slot 6 coincides with the shop window in the frame 5 of the gun, and the slot 7 is combined with the tabs 8 with the latch 15 of the gun. The holes 9, in this case, are combined with the hole formed by the slot 16 of the pin 2 and the wall of the latch 15;

e) insert the end of the pin 4 into the hole 9 through the slot 16 into the latch 15 and withdraw it from the opposite side of the latch through the hole 9 in the second protrusion 8. The check 4 is fixed inside the slot 16 by a bend 24. The hole of the ring 25 of the check is installed, across traction on its edge, half protruding beyond the edge.

Sector site 10 of the rod 1, when securing the rod with a check 4, is set to fit to the gun handle under the trigger guard in the lower part of the handle, 3-4 times back from the handle under the action of the latch spring 15. The fuse 11 is pressed against the surface of the handle (Figure 1).

The magazine 23 is inserted through the slot 6 of the rod 1 into the window for the magazine of the frame (5) of the pistol grip, compressing the ejector spring 3 against the side tabs of the lid 22 and secured by the protrusion 26 by the latch 15. The fixing of the magazine is no different from fixing it in the gun, not having an ejector.

The device operates as follows.

When shooting, the pistol is held in hand (in either) by a conventional grip. At the same time, the little finger lies on the sector site 10, and the ring finger presses the fuse 11 to the handle (Figure 2).

The bend 14 on the fuse 11 in this position prevents the pad 10 from being pressed against the surface of the handle of the gun and the movement of the rod 1 toward the latch 15. This allows the gun to be used without fear of unauthorized throwing of the magazine. The ergonomics of the handle when gripping the handle with the installed ejector store does not change due to its small size in the grip area of the hand.

If necessary, store replacements weaken the grip of the handle with the ring finger. In this case, the fuse 11 deviates from the plane of the handle by an angle of 90-45 °, releasing the pad 10 from the stop through its bend 14 into the surface of the handle. The little finger, at the same time, continues to press on the pad 10, and it moves to the surface of the handle. The rod 1 moves along the end of the pistol grip, pushing the latch 15 away from the little finger through the pin 4. When the protrusion 26 of the magazine disengages from the catch of the latch 15, the latch continues to be withdrawn from the magazine under the pressure of the rod 1. The magazine is released from the hook and is completely free (without friction on the latch 15), due to the continued pressure of the little finger on the pad 10, and the spring 3, at the same time, throws the magazine out of the pistol grip, independently, the shutter is in the “shutter delay” position or in the closed position, at any position and gun handles in space. The same operations are easily performed with gloves in winter conditions.

The test results showed that the magazine ejector is a workable, convenient and safe device that accelerates the magazine replacement (two aimed shots with magazine replacement can be performed in 2.5 s), which allows working with a gun in gloves in winter conditions, at any position of the gun handle in the space, with any hand and not preventing the insertion and removal of the gun from the closed holster. The installation time of the ejector parts on the gun does not exceed 1 min. The weight of the device does not exceed 10 g. If desired, the magazine can be removed from the gun as if the ejector was not on the gun - by pressing the fingers of the other hand on the latch.
