Description
2 PCT/IB2018/050079 Locking mechanism of a slide of a weapon Technical field The invention relates to a locking mechanism of a slide of a weapon, especially of a self-loading pistol, with a stationary barrel mounted fixedly in a frame, on which a slide is mounted displaceably for forward and backward movement.
Background art GB 127642A discloses an automatic rifle, the automation of which is based on the use of the energy of the powder gases discharged from the barrel channel.
Under the barrel is arranged a piston which moves forwards and actuates a mechanism consisting of a complex lever system, telescopic connecting rods, a sliding element and a row of springs. After a pressure drop in the barrel, the springs stretched by the piston are activated by a locking mechanism to reload the rifle whereby the locking mechanism first opens and then closes due to the force of the springs.
The locking mechanism consists of two parts, the body of the slide and the screw of the slide. The barrel is locked with a screw that rotates around its axis during the firing, and its catches fit into the protrusions of the barrel bushing in which the rifle barrel is mounted.
The device is too complicated and cannot be used for self-loading pistols.
Known is the pistol CZ-83 produced by Oeska zbrojovka, Uhersky Brod, Czech Republic (www.czub.cz), as well as the pistol SIG-Sauer P232 produced by J. P. Sauer & Sohn GmbH, Germany (www.sauer-waffen.de; www.sich sauerde).
These are self-loading-pistols, whose barrel is fixedly and non-movably mounted on a frame. During the firing process the locking of a barrel channel till the moment of the ejection of a cartridge out of the channel and a pressure drop of powder gases take place due to the force of inertia of a massive slide and due to the force of a recoil spring, maintaining the slide during shooting in the frontmost position.
The important features of the above-mentioned pistols include a high degree of accuracy of shooting, since the barrel is fixedly mounted in the frame of the pistol, as well as the simplicity of the construction.
The drawback of pistols with this system of locking the slide is the fact that it is not possible to use high-performance cartridges, since to be able to use such cartridges it would be necessary to increase considerably the weight of the slide, which would lead to an increase in the weight of the whole pistol and would result in a great slide impact force between the slide and the pistol frame on reaching its rearmost position after the shot.
The aim of the invention is to provide a locking mechanism of a slide during the shot of a self-loading pistol with a barrel, which is fixedly and non-movably mounted in a frame, which allows to use high-performance cartridges for shooting without increasing the weight of the slide.
Principle of the invention The above-mentioned aim is achieved by a locking mechanism of a slide of a weapon according to the present invention, whose principle consists in that between the movable slide and the non-movable frame of the weapon under the barrel is arranged a pair of levers which are rotatably connected to each other by a common axis, whereby the common axis of the pair of levers is situated under a line interlaid by the outer axes of rotation of the pair of levers.
During the shot, the energy of the recoil movement strives to reduce the internal angle between the front lever and the rear lever and move their common axis downwards, with the resistive force in the initial phase of the shot resisting inertia force of the slide, the elastic force of the retractable spring, the elastic force of the material of the levers and their connection, the frictional force in the connection, as well as the mounting of the levers. It is only after overcoming these forces that the slide begins to move backwards. This ensures

During the firing process the locking of a barrel channel till the moment of the ejection of a cartridge out of the channel and a pressure drop of powder gases take place due to the force of inertia of a massive slide and due to the force of a recoil spring, maintaining the slide during shooting in the frontmost position.
The important features of the above-mentioned pistols include a high degree of accuracy of shooting, since the barrel is fixedly mounted in the frame of the pistol, as well as the simplicity of the construction.
The drawback of pistols with this system of locking the slide is the fact that it is not possible to use high-performance cartridges, since to be able to use such cartridges it would be necessary to increase considerably the weight of the slide, which would lead to an increase in the weight of the whole pistol and would result in a great slide impact force between the slide and the pistol frame on reaching its rearmost position after the shot.
The aim of the invention is to provide a locking mechanism of a slide during the shot of a self-loading pistol with a barrel, which is fixedly and non-movably mounted in a frame, which allows to use high-performance cartridges for shooting without increasing the weight of the slide.
Principle of the invention The above-mentioned aim is achieved by a locking mechanism of a slide of a weapon according to the present invention, whose principle consists in that between the movable slide and the non-movable frame of the weapon under the barrel is arranged a pair of levers which are rotatably connected to each other by a common axis, whereby the common axis of the pair of levers is situated under a line interlaid by the outer axes of rotation of the pair of levers.
During the shot, the energy of the recoil movement strives to reduce the internal angle between the front lever and the rear lever and move their common axis downwards, with the resistive force in the initial phase of the shot resisting inertia force of the slide, the elastic force of the retractable spring, the elastic force of the material of the levers and their connection, the frictional force in the connection, as well as the mounting of the levers. It is only after overcoming these forces that the slide begins to move backwards. This ensures
3 the possibility of shooting with high-performance cartridges, while maintaining low weight of the slide and of the entire weapon.
The exact value of the internal angle is determined according to the performance of the projectile and the construction of a specific embodiment of a pistol or another type of a weapon.
In a preferred embodiment, the pair of levers consists of a rear lever, which is rotatably mounted on the rear axis situated in the front part of the frame under the barrel, and a front lever, which is rotatably mounted on the front axis situated in the front part of the slide under the barrel, whereby the rear lever and the front lever are rotatably connected by a common axis, the internal angle between the rear lever and the front lever being less than 1800 .
In order to facilitate the handling of the weapon before the first shot, on either side of the common axis of the rear lever and the front lever are provided grippers for to be gripped by the shooter's fingers when pulling the slide.
In a specific embodiment, the retractable spring is disposed between the rear lever and the front lever and is formed by two arms, whereby the rear arm leans against the top of the rear lever and the front leg leans against the top of the front lever.
Furthermore, it is advantageous if the retractable spring is arranged on the common axis of the rear lever and the front lever.
In another alternative unillustrated embodiment, the retractable spring is mounted between the rear lever and the front part of the frame of the weapon.
In another alternative embodiment, the retractable spring is mounted on the barrel, which acts as a guide for it and which leans by one end against the frame and by the other end against the slide.
Also, the retractable spring may be mounted under the barrel on a separate guide, which is parallel to the barrel, and leans by one end against the frame and by the other end against the front part of the slide.

6 In another alternative unillustrated embodiment, the retractable spring 10 is arranged on the barrel 3, which acts as a guide for it, whereby the retractable spring leans by one end against the frame 1 a by the other end against the front part of the slide 4.
In yet another alternative unillustrated embodiment, the retractable spring is disposed under the barrel 3 on a separate guide, which is parallel to the barrel 3 and leans by one end against the frame 1 and by the other end against the front part of the slide 4.

To load a pistol, it is necessary to hold the pistol by the grip 2 with one hand, with two fingers grasping the grippers 91 arranged on the common axis 9, which are in the illustrated embodiment formed by knurled knobs, and pull them vigorously downwards and backwards towards the stop and then let go.
Simultaneously, the rear lever 5 turns on the rear axis 6 anticlockwise and by means of the common axis 9 pulls the front lever 7 downwards and backwards, which, turning on the front axis 8 connected to the front lower part of the slide 4, pulls the slide 4 backwards. The slide 4 reaches its rearmost position. At the same time, the retractable spring 10, which leans against the two levers 5 and

To load a pistol, it is necessary to hold the pistol by the grip 2 with one hand, with two fingers grasping the grippers 91 arranged on the common axis 9, which are in the illustrated embodiment formed by knurled knobs, and pull them vigorously downwards and backwards towards the stop and then let go.
Simultaneously, the rear lever 5 turns on the rear axis 6 anticlockwise and by means of the common axis 9 pulls the front lever 7 downwards and backwards, which, turning on the front axis 8 connected to the front lower part of the slide 4, pulls the slide 4 backwards. The slide 4 reaches its rearmost position. At the same time, the retractable spring 10, which leans against the two levers 5 and
7, is compressed. After releasing the grippers, the retractable spring 10 begins to move the levers 5 and 7 vigorously away from each other. The rear lever 5 rotates around the rear axis 6 mounted in the front part of the non-movable the frame 1, whereby the common axis 9 returns to its initial position and moves towards the barrel 3. As a result, also the front lever 7 returns to its initial position and pushes the slide 4 forwards by the pressure through the front axis
8 to its front lower part. During the movement forwards the slide 4 in a known manner pulls the upper projectile from the magazine and feed is to a cartridge chamber of the barrel 3 of the pistol to perform a shot. Once the slide 4 has reached its frontmost position, it closes by the cartridge case of the projectile the channel of the barrel 3. The system of levers 5 and 7 expands from the rear axis 6 in the front part of the frame 1 forwards to the front axis 8 in the front lower part of the slide 4, and forms by its shape a broken line having an internal angle less than 180 0. Thus, the slide 4 is blocked before the shot. In this position the pistol is loaded and ready to shoot.
During the firing process, the bullet moves under the pressure of the powder gases through the channel of the barrel 3. Simultaneously, the powder gases through the ends of the cartridge casing push on the slide 4, pass it the energy of the recoil movement and try to move it backwards. The slide 4 by the front lower part passes the pressure of the powder gases to the front lever 7, through the common axis 9 to the rear lever 5 and through the rear lever 5 and the rear axis 6 to the front wall of the non-movable frame 1 of the pistol.
The energy of the recoil movement being passed tries to reduce the internal angle between the front lever 7 and the rear lever 5, bring the front axis 8 and the rear axis 6, to each other, move down the common axis 9 and compress the retractable spring 10. Several forces resist the force of the recoil movement, which do not allow to move the slide 4 backwards in the initial phase of the shot:
the inertia force of the slide 4 itself, the elastic force of the retractable spring 10 of the slide 4, the elastic force of the material of the levers 5 and 7 and their axes 6, 8 and 9 and the frictional force in the axes 6, 8 and 9.
During the movement of the bullet through the channel of the barrel 3 the slide 4 obtains enough energy of the powder gases for overcoming the resistance of the above-mentioned forces which maintain the slide 4 in the frontmost position. As a result, after the ejection of the bullet out of the channel of the barrel 3 the slide 4 pushes down the common axis 9 of the levers 5 and 7 and begins to move backwards, whereby it makes the levers 5 and 7 move towards by reducing the internal angle between them and compresses the retractable spring 10. During the movement backwards the slide 4 pulls the used cartridge case in a known manner from the cartridge chamber of the barrel 3, the used cartridge being subsequently propelled out by an unillustrated ejector. Once the slide 4 has reached its rear position and strikes the stops on the non-movable frame 1, the slide 4 begins due to the action of the retractable spring 10 move forwards and feeds the next projectile from the magazine to the cartridge chamber of the barrel 3 to perform the next shot. Once the slide 4 has reached its frontmost position, it closes by means of a cartridge case the channel of the barrel 3. The system of levers 5 and 7 expands from the rear axis 6 in the front part of the non-movable frame 1 forwards to the front axis 8 in the front lower part of the slide 4 and forms by its shape a broken line having an internal angle less than 1800, thereby and the slide 4 is blocked before the shot.
The pistol is now ready to fire again.
In this manner, the invention provides, as compared with the background art, the possibility of shooting from a pistol with a stationary barrel fixedly mounted on the frame, using high-performance cartridges, while maintaining low weight of the slide and of the whole pistol.
The same locking mechanism of a slide 4 during the firing process can be used on automatic shotguns, automatic rifles, self-loading hunting guns and machine guns. A t the same time, the main principles of the locking mechanism must be maintained:
- the rear lever 5 and the front lever 7 must be rotatably connected to each other;
- the system of levers 5 and 7 must be located between the movable slide 4 and the non-movable frame 1 of the weapon;
- the common axis 9 of the rear lever 5 and the front lever 7 must not be situated in the line interlaid with the rear axis 6 and the front axis 8, and so the levers 5 and 7 must form a broken line having an internal angle opposite the barrel 3 less than 180 and having a corresponding external angle greater than 180';
Exact values of the angles are determined according to the performance of the cartridge and the construction of a specific embodiment of the weapon.
Industrial applicability The invention is intended for weapons with a stationary barrel fixedly mounted in a frame for shooting with high-performance cartridges.
During the firing process, the bullet moves under the pressure of the powder gases through the channel of the barrel 3. Simultaneously, the powder gases through the ends of the cartridge casing push on the slide 4, pass it the energy of the recoil movement and try to move it backwards. The slide 4 by the front lower part passes the pressure of the powder gases to the front lever 7, through the common axis 9 to the rear lever 5 and through the rear lever 5 and the rear axis 6 to the front wall of the non-movable frame 1 of the pistol.
The energy of the recoil movement being passed tries to reduce the internal angle between the front lever 7 and the rear lever 5, bring the front axis 8 and the rear axis 6, to each other, move down the common axis 9 and compress the retractable spring 10. Several forces resist the force of the recoil movement, which do not allow to move the slide 4 backwards in the initial phase of the shot:
the inertia force of the slide 4 itself, the elastic force of the retractable spring 10 of the slide 4, the elastic force of the material of the levers 5 and 7 and their axes 6, 8 and 9 and the frictional force in the axes 6, 8 and 9.
During the movement of the bullet through the channel of the barrel 3 the slide 4 obtains enough energy of the powder gases for overcoming the resistance of the above-mentioned forces which maintain the slide 4 in the frontmost position. As a result, after the ejection of the bullet out of the channel of the barrel 3 the slide 4 pushes down the common axis 9 of the levers 5 and 7 and begins to move backwards, whereby it makes the levers 5 and 7 move towards by reducing the internal angle between them and compresses the retractable spring 10. During the movement backwards the slide 4 pulls the used cartridge case in a known manner from the cartridge chamber of the barrel 3, the used cartridge being subsequently propelled out by an unillustrated ejector. Once the slide 4 has reached its rear position and strikes the stops on the non-movable frame 1, the slide 4 begins due to the action of the retractable spring 10 move forwards and feeds the next projectile from the magazine to the cartridge chamber of the barrel 3 to perform the next shot. Once the slide 4 has reached its frontmost position, it closes by means of a cartridge case the channel of the barrel 3. The system of levers 5 and 7 expands from the rear axis 6 in the front part of the non-movable frame 1 forwards to the front axis 8 in the front lower part of the slide 4 and forms by its shape a broken line having an internal angle less than 1800, thereby and the slide 4 is blocked before the shot.

- the system of levers 5 and 7 must be located between the movable slide 4 and the non-movable frame 1 of the weapon;
- the common axis 9 of the rear lever 5 and the front lever 7 must not be situated in the line interlaid with the rear axis 6 and the front axis 8, and so the levers 5 and 7 must form a broken line having an internal angle opposite the barrel 3 less than 180 and having a corresponding external angle greater than 180';
Exact values of the angles are determined according to the performance of the cartridge and the construction of a specific embodiment of the weapon.
Industrial applicability The invention is intended for weapons with a stationary barrel fixedly mounted in a frame for shooting with high-performance cartridges.
