Description

TECHNICAL FIELD

The invention refers that when firing does not deviate from the sight line in vertical direction, that shall be applied, either as a means of self-defense, or as a hand-held fire weapon for sports, military and hunting firing,

PRIOR ART

When firing with pistols—representatives of the well-known systems of hand-held smallarms, it is found shifting of the barrel “upwards”, because of the following:

When firing with pistols from the well-known systems, there are reaction forces created (the so-called recoil), directed “backwards” along the bore line of the weapon, as these forces create a torque round the weapon support point and as a result the front end of the barrel jumps “upwards”. The reason causing the motion is the disposition of the bore line above the place of weapon retaining, i. e. above the support point.

This effect is obtained when firing with pistols, one-charge and many-charge non-automatic hand-held weapons and is the reason for their basic disadvantage—the low rate of fire accuracy. (1)/“Reference Book of Smallarms”, A. B. Zhuk/

At automatic self-loading weapons, the deviation from the sight line, when firing, is accelerated due to the motion of bolt parts, as the change in location of weight centres of elements of the weapon at high speeds creates inertia forces and moments additionally that aggravate accuracy.

In order to overcome the action of inertia forces during fire at this type of weapons, extra measures are taken as: corrections in sighting devices; mounting muzzle compensators, balances and retarders of fire rate; introducing disconnectors and buffers.

A disadvantage of automatic pistols is the complicated design that leads to difficulties in their handling. (2)/“Reference Book of Smallarms”, A. B. Zhuk/

There are pistols known where the barrel axis is guided to the weapon support point (the firer's palm) and it is avoided bouncing the pistol “upwards”. (3)/U.S. Pat. No. 4 268 987 and pistols “Tourbean” 1883 and “Protector” 1882/ “Reference Book of Smallarms”, A. B. Zhuk//

Disadvantages of these pistols are: the complicated design that hampers usage, reloading, reduces reliability, requires special ammunition; bad ergonomics and low effectiveness of firing.

It is known a sports pistol of T-shaped location of grip and barrel, consisting of a casing provided with a grip, a barrel, a trigger located above the barrel within the zone between the muzzle rear end and the grip, a bolt, a striker, a fire spring and a magazine. (4)/History of Tula Military Plant/

Disadvantages of this pistol are the risen overalls and its complex design that make its handling difficult

The famous sports pistol can not be regarded as an analogue of the present invention, as it is provided with special devices ensuring improved aiming fire that complicates its design and makes it importable.

It is known a pistol consisting of a casing, a barrel, a trigger, a striker, a fire spring and a magazine, the casing and the barrel being located in a heat-insulating grip and forming a T-shape connection by means of a dismountable multi-element clamp provided with a trigger mounted on it and situated above the bore line of the barrel within the zone between the front and the rear muzzle ends connected with the feeding mechanism consisting of a feeding lever, a feeding pawl being fixed on its opposite end by means of a trigger mechanism consisting of a transfer bar geared into a striker lever provided with a cog so that the casing is provided with an inner bore of rectangular cross-section and set inside it a magazine provided with a cartridge nests set in a row and saw-like cogs set along the height of the side neighbour walls just before the rear wall of the magazine and fixing grooves located along the axes direction of cartridge nests so that the number of saw-like cogs situated on each of the neighbour walls of the magazine corresponds to the number of cartridge nests, the casing being closed from above and a striker, a fire-spring, an upper stop and a lower stop being fastened to its rear wall and a profile opening. (5))/FR-A-550 415/

The disadvantages of this pistol are the complicated design which includes a multi-element clamp connecting the barrel with casing upper end, the indirect connection between the trigger and the feeding mechanism by means of the trigger mechanism the result being a difficult use and reloading, a decreased reliability and a low fire efficiency. The ergonomics and the heat insulation of the grip are not reliable enough witch determine the insufficient fire accuracy.

The goal of this invention is to be created a portable pistol for self-protection of T-shaped disposition of the barrel and the casing, reduced weight and overalls of the weapon, high accuracy of fire and convenient handling.

HANDLING THE INVENTION

When using the Pistol, subject of the present invention, of design described in Example 1 , cartridges are arranged in a metallic magazine with cartridge nests formed inside and the magazine is moved in a step-like down-up way behind the barrel through the action of the trigger pull./ FIG. 1 , & FIG. 3 /

Handling is carried out in the following way:

After filling the magazine 15 with cartridges in the cartridge nests 15 , it is proceeded with the pistol loading. To this end, the filled magazine 14 is inserted into the grip 3 through the lower opening of the inner bore 13 from the bottom to the top till the moment the first from the saw-like cogs 16 , located along the right neighbour wall, contacts the short arm 24 of the V-shape upper stop 20 . At the same time the lower stop 21 situated on the opposite wall locks it in this position so that the top most cartridge is set under the bore line. Through the profile opening 22 in the rear wall of the casing 1 , the feeding pawl 12 is facing the saw-like cogs 16 of the magazine 14 .

Pulling the trigger 5 brings simultaneously to rotating the striker 18 “backwards” round its axis set under the bore line, through the action of the transfer bar 8 that draws out the striker lever 9 upwards, the cog 10 pushes the long arm 25 of the upper stop 20 “backwards” and takes out the short arm 24 from gearing with the magazine 14 .

From the other end the feeding pawl 12 starts gearing with the fixing grooves 17 of the magazine 14 and drawing it upwards sliding along the vertical edge of the profile opening 22 . When the feeding pawl 12 contacts with the upper edge of the profile opening 22 , it changes the motion direction into, “forward” locking the magazine 14 to the casing 1 . Besides, the first cartridge has been fed against the barrel 2 . At the same time the transfer bar 7 releases the striker lever 9 and through the action of the fire spring 19 , the striker 18 hits the cartridge primer and takes a shot.

Through the action of the spring 66 depressing its upper end, the upper stop 20 enters over the subsequent saw-like cog 16 of the magazine 14 along with the striker 18 , as its short arm 24 gears with the saw-like cogs 16 of the magazine 14 and its long arm 25 remains behind the cog 10 of the striker lever 9 and the lower stop 21 has already missed one saw-like cog 16 and is geared under the next one. Releasing the trigger 5 , which is under-spring, brings to going out of the feeding pawl 12 from the fixing groove 17 of the magazine 14 and reversing in home position. The transfer bar 7 moves downward till the cog 10 gears again with the striker lever 9 . So, the pistol is ready for the next shot. After firing the cartridges from the magazine 14 or upon other necessity, the lower end of the lower stop 21 is pushed forward, so that its lower under-spring end is below the level of the grip 3 and the magazine 14 goes out through the action of its own weight. Afterwards the pistol is loaded with a second filled up magazine 14 or the cases of the magazine already taken out are replaced with cartridges.

When using the pistol, subject of the present invention, of design described in Example 2 , cartridges are arranged in a metallic magazine with cartridge nests formed inside in a row and the magazine is moved in a step-like up-down way behind the barrel through the action of the feeding spring folded in advance./ FIG. 1 , FIG. 4 , FIG. 5 & FIG. 6 /

Handling is carried out in the following way:

The magazine 14 is set in the inner bore 13 of the casing 1 . To load the pistol, the grip 39 is withdrawn backwards, as the cap 31 is opened up to 90°, so that the upper stop 36 , the lower stop 37 , the latch 38 of T-shape, the striker 18 and the fire spring 19 are moved along with the cap 31 backwards and upwards, as the excess to the magazine 14 is released being in lower extreme position depressed by the feeding spring 44 . The arm 32 of the cap 31 pushes downward the elevating frame 34 till the elevating cog 35 seizes the lock pin 30 situated at the lowest point of the vertical slot 43 . Cartridges are set into cartridge nests 15 . After loading the magazine 14 , the cap 31 is closed. The elevating draws the magazine 14 upwards so that the feeding spring 44 is depressed, so when reaching an upper position, the elevating cog 35 releases the lock pin 30 . At the same time the lower stop 37 has entered the zone of gearing with the lowest saw-like cogl 6 of the magazine 14 . Through the action of the feeding spring 44 the lower stop moves downward along its elongated opening. The upper stop 36 gears with the lowest saw-like cog 16 of the magazine 14 from its opposite side. The first cartridge has been introduced into the barrel 2 and the pistol is ready for fire.

Pulling the trigger 5 brings simultaneously to rotating the striker 18 “backwards” round its axis set under the bore line, through the action of the transfer bar 8 that draws out the striker lever 9 upwards, the cog 10 pushes the short arm 24 of the lower stop 37 “backwards” and takes out the long arm 25 from gearing with the magazine 14 , so that its long arm 25 skips the top of the saw-like cog 16 and goes out of gearing with it and through the action of the spring 67 , the lower stop 37 raises along its elongated opening clamping into the inter-cogs area At the same time the cradle 27 geared into the trigger 5 turns round and withdraws the fixing pawl 29 along the fixing slot 41 into the subsequent fixing groove 17 of the magazine 14 .

Afterwards the transfer bar 8 releases the striker lever 9 and through the action of the fire spring 19 , the striker 18 hits the cartridge primer fires a shot

Releasing the trigger 5 brings to pushing the fixing pawl 29 from the current fixing groove 17 of the magazine 14 . The so-released magazine 14 , through the action of the feeding spring 44 , goes downward and the lower stop 37 meets the next saw-like cog 16 of the magazine 14 with its long arm 25 , descending along its elongated opening, depressing the spring 67 , so that the next cartridge has been introduced into the barrel 2 . After firing all the cartridges from the magazine, the cap 31 is unclamped by drawing the grip 39 backwards. Meanwhile, the ejector 33 has remained before the rims of cases moving downwards and when opening the cap 31 , seizes and draws them from cartridge nests 15 of the magazine 14 , so that the magazine 14 is ready for refilling.

The Pistol, subject of the present invention, of design described in Example 3 , is a self-loading pistol and functions according to the system-long stroke of barrel forward at an immovable bolt./ FIG. 7 , FIG. 8 /

Its handling is carried out in the following way:

After filling the magazine 47 with cartridges, it is proceeded with pistol loading. To this end the filled magazine 47 is thrust into the grip 3 through the lower opening of the inner bore 13 down-up till the moment when the closing cover 49 fixes to the casing 1 by means of the S-shaped latch 59 , so that the upper cartridge is clamped to the outer surface of the barrel 2 within the thickened zone. After that the grip 39 of the cover 54 is withdrawn backwards till stoppage. By the kinematics chain, the cover 54 , the cradle 55 , the guiding pawl 65 and the cross groove 53 , the barrel 2 is pushed forward depressing the spiral recoil spring 50 . The upper cartridge is pushed upwards by the pushing spring 48 of the magazine 47 till its rim enters the ejector 57 . When releasing the grip 39 of the cover 54 , through the action of the spiral recoil spring 50 , the barrel 2 reverses backwards and thrusts onto the fed cartridge. The cover 54 also returns back and closes from above the inner bore 13 of the casing operating as a case outlet. The pistol is ready for fire, as the first cartridge has been introduced into the barrel 2 .

Pulling the trigger 5 cocks the striker 18 by means of the transfer bar 8 , afterwards it releases the striker lever 9 and through the action of the fire spring 19 , the striker 18 hits the cartridge primer and fires.

When firing, the bullet sets forth into the barrel and the friction forces affect it. The barrel shifts forward, as moves simultaneously linear and rotary motion round its axis and as a result of sliding the cogs 61 along the guiding grooves 52 , slant longitudinally towards the bore line. Shifting forward, the barrel 2 goes out of the case scope, opens the cover 54 and folds the spiral recoil spring 50 . When reaching front extreme position, the end of the cradle 55 , moving backward, hits the upper end of the deflector 56 , so that the pawl 58 knocks out the case from the ejector 57 and it flies upwards through the case outlet. At the same time the unoccupied place has been taken from the next cartridge, so that the barrel 2 , returned back by the spiral recoil spring 50 , is thrust onto it. After releasing the trigger 5 , the pistol is ready for the next firing. Reloading is carried out, as the S-shaped latch 59 is pressed backward, so that the emptied magazine 14 is taken out and replaced with a newly-filled one.
