ABSTRACT:
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.
TECHNICAL DESCRIPTION
The essence of the invention is the design of a Pistol that consists 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. The trigger connected with the feeding mechanism consisting of a feeding lever, a feeding pawl is 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. The casing is provided with an inner bore of rectangular cross-section and set inside it. The magazine is provided with 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 is closed from above and a striker, a fire-spring, an upper stop and a lower stop are fastened to its rear wall and a profile opening. The clamp is an integral one and connects the upper part of the casing with the front end of the barrel. The trigger is connected with both the trigger mechanism and the feeding mechanism. The fixing grooves of the magazine are located along the axes direction of the cartridge nests between the highest and the lowest points along the height of the saw-like cogs. The striker is a metallic circular sector with a fire pin in one of arc ends with an opening in the centre of the circle situated below the bore line . The point of the fire pin coincides with the bore line. The fire spring is connected with the arc end opposite the fire pin, the upper stop having the form of a reverse “Y” provided with a short arm and a long arm and is situated above the bore line,. The lower stop being situated below the striker pin so that its lower under-spring end is below the level of the grip.
As a second variant of the invention a Pistol consists 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. The trigger is connected with the trigger mechanism consisting of a transfer bar geared into a striker lever provided with a cog. The casing is provided with an inner bore of rectangular cross-section and set inside it. The magazine is provided with 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 are 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 is closed from above a striker, a fire spring are fastened to its rear wall and a profile
