Abstract
A weapon includes a stationary barrel mounted fixedly in a frame, and a slide movably mounted to the frame for forward and backward displacement relative to the frame. A locking mechanism for the slide includes a retractable spring acting on the slide in a direction towards a forward-most position of the slide, and a pair of levers arranged under the barrel between the slide and the frame. The pair of have opposite end axes of rotation and are mutually rotatably connected by a common axis. The common axis lies under a line that extends between the end axes of rotation of the pair of levers.
Description
- 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 the slide is mounted displaceably for forward and backward movement.
- 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 forward 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 Česká zbrojovka, Uherský 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.sig-sauer.de).
- 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.
- An aim of the invention is to provide a locking mechanism of a slide during the shot of a self-loading pistol having a barrel that 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. Additional objects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention.
- The above-mentioned objects are 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 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 may be less than 180°.
- 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 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 arm 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 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 the spring, and 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.
- The principle of the invention is schematically represented in the drawings of an exemplary embodiment of a self-loading pistol, wherein:
-
FIG. 1 shows an overall view of the pistol, wherein the position of the components of the locking mechanism of the slide of the pistol are in the starting state before the shot; and -
FIG. 2 shows an overall view of the pistol, wherein with the position of the components of the locking mechanism of the slide of the pistol are shown after the shot and after moving the slide to the rearmost position. - Reference will now be made to embodiments of the invention, one or more examples of which are shown in the drawings. Each embodiment is provided by way of explanation of the invention, and not as a limitation of the invention. For example features illustrated or described as part of one embodiment can be combined with another embodiment to yield still another embodiment. It is intended that the present invention include these and other modifications and variations to the embodiments described herein.
- The locking mechanism of a slide during shooting according to the invention will be described based on an exemplary embodiment of a pistol. The locking mechanism can be used on shotguns, such as automatic shotguns, automatic rifles, self-loading hunting guns, and machine guns. It is important to note that only the components which are directly connected with the invention and which are shown in the drawing will be described here.
- The pistol in the exemplary embodiment comprises a
frame 1 provided with agrip 2 for holding the pistol with the shooter's hand. In theframe 1 is fixedly mounted thebarrel 3, in which a well-known unillustrated barrel channel is formed. On theframe 1 is provided a well-known unillustrated guide, on which is reversibly slidably mounted aslide 4, able to move between a front position and rear position. - In the front part of the
frame 1 under thebarrel 3 is arranged arear axis 6, on which arear lever 5 is, by its rear end, mounted displaceably for rotatable movement with respect to theframe 1. The rotation of therear lever 5 with respect to theframe 1 can be realized either by the rotatable mounting of therear axis 6 on theframe 1 and by the fixed mounting of therear lever 5 on therear axis 6, by the fixed mounting of therear axis 6 on theframe 1 and by the rotatable mounting of therear lever 5 on therear axis 6, or by the rotatable mounting of therear axis 6 on theframe 1 by the rotatable mounting of therear lever 5 on therear axis 6. In an unillustrated embodiment therear axis 6 may be a part of theframe 1 or of therear lever 5. - In the front part of the
slide 4 under thebarrel 3 is arranged afront axis 8, on which afront lever 7 is, by its front end, mounted displaceably for rotatable movement with respect to theslide 4. The rotation of thefront lever 7 with respect to theslide 4 can be realized either by the rotatable mounting of thefront axis 8 on theslide 4 and by the fixed mounting of thefront lever 7 on thefront axis 8, or by the fixed mounting of thefront axis 8 on theslide 4 and by the rotatable mounting of thefront lever 7 on thefront axis 8, or by the rotatable mounting of thefront axis 8 on theslide 4 and by the rotatable mounting of thefront lever 7 on thefront axis 8. In an unillustrated embodiment, thefront axis 8 may be a part of theslide 4 or thefront lever 7. - The free end of the
front lever 7 is rotatably connected to the free end of therear lever 5 by acommon axis 9, which is movable in the space under thebarrel 3 and theslide 4. On either side at the end of thecommon axis 9 are providedgrippers 91 to be gripped by the shooter's fingers when pulling theslide 4. On thecommon axis 9 is also mounted aretractable spring 10 with two arms, whereby the front arm leans against the top of thefront lever 7 and the rear arm leans against the top of therear lever 5. Thecommon axis 9 is arranged with respect to thebarrel 3 under a conceived connecting line of thefront axis 8 and therear axis 6. The angle directed to thebarrel 3 between therear lever 5 and thefront lever 7 will be hereinafter referred to as an internal angle between these twolevers retractable spring 10 lean against thefront lever 7 and therear lever 5 in the direction of thelevers front lever 7 and therear lever 5, whereby this internal angle is always less than 180°. The strength of theretractable spring 10 maintains theslide 4 in the front position, acting on thecommon axis 9 in the direction towards thebarrel 3. In an unillustrated embodiment, thecommon axis 9 may be a part of therear lever 5 or thefront lever 7. - In an alternative unillustrated embodiment, the
retractable spring 10 may be mounted on therear axis 6 and may lean by one end against theframe 1 and by the other end on therear arm 5, its strength acting clockwise, that is in the direction towards thebarrel 3. - In another alternative unillustrated embodiment, the
retractable spring 10 is arranged on thebarrel 3, which acts as a guide for it, whereby the retractable spring leans by one end against theframe 1 and by the other end against the front part of theslide 4. - In yet another alternative unillustrated embodiment, the retractable spring is disposed under the
barrel 3 on a separate guide, which is parallel to thebarrel 3 and leans by one end against theframe 1 and by the other end against the front part of theslide 4. - Depending on the construction of the weapon, there are also other suitable places of mounting the
retractable spring 10, whose strength always acts on theslide 4 in the direction towards its frontmost position. - To load a pistol, it is necessary to hold the pistol by the
grip 2 with one hand, with two fingers grasping thegrippers 91 arranged on thecommon 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, therear lever 5 turns on therear axis 6 anticlockwise and by means of thecommon axis 9 pulls thefront lever 7 downwards and backwards, which, turning on thefront axis 8 connected to the front lower part of theslide 4, pulls theslide 4 backwards. Theslide 4 reaches its rearmost position. At the same time, theretractable spring 10, which leans against the twolevers retractable spring 10 begins to move thelevers rear lever 5 rotates around therear axis 6 mounted in the front part of thenon-movable frame 1, whereby thecommon axis 9 returns to its initial position and moves towards thebarrel 3. As a result, also thefront lever 7 returns to its initial position and pushes theslide 4 forwards by the pressure through thefront axis 8 to its front lower part. During the movement forwards theslide 4, in a known manner, pulls the upper projectile from the magazine and feeds it to a cartridge chamber of thebarrel 3 of the pistol to perform a shot. Once theslide 4 has reached its frontmost position, it closes by the cartridge case of the projectile the channel of thebarrel 3. The system oflevers rear axis 6 in the front part of theframe 1 forwards to thefront axis 8 in the front lower part of theslide 4, and forms by its shape a broken line having an internal angle less than 180°. Thus, theslide 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 theslide 4 and pass the energy of the recoil movement to the slide and try to move theslide 4 backwards. Theslide 4 by the front lower part passes the pressure of the powder gases to thefront lever 7, through thecommon axis 9 to therear lever 5 and through therear lever 5 and therear axis 6 to the front wall of thenon-movable frame 1 of the pistol. The energy of the recoil movement being passed tries to reduce the internal angle between thefront lever 7 and therear lever 5, bring thefront axis 8 and therear axis 6 to each other, move down thecommon axis 9, and compress theretractable spring 10. Several forces resist the force of the recoil movement and do not allow theslide 4 to move backwards in the initial phase of the shot: the inertia force of theslide 4 itself, the elastic force of theretractable spring 10 of theslide 4, the elastic force of the material of thelevers axes axes - During the movement of the bullet through the channel of the
barrel 3, theslide 4 obtains enough energy of the powder gases to overcome the resistance of the above-mentioned forces that maintain theslide 4 in the frontmost position. As a result, after the ejection of the bullet out of the channel of thebarrel 3 theslide 4 pushes down thecommon axis 9 of thelevers levers retractable spring 10. During the movement backwards, theslide 4 pulls the used cartridge case in a known manner from the cartridge chamber of thebarrel 3, the used cartridge being subsequently propelled out by an unillustrated ejector. Once theslide 4 has reached its rear position and strikes the stops on thenon-movable frame 1, theslide 4 begins, due to the action of theretractable spring 10, to move forward and feeds the next projectile from the magazine to the cartridge chamber of thebarrel 3 to perform the next shot. Once theslide 4 has reached its frontmost position, it closes by means of a cartridge case the channel of thebarrel 3. The system oflevers rear axis 6 in the front part of thenon-movable frame 1 forwards to thefront axis 8 in the front lower part of theslide 4 and forms by its shape a broken line having an internal angle less than 180°, thereby theslide 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. At the same time, the main principles of the locking mechanism must be maintained: -
- the
rear lever 5 and thefront lever 7 must be rotatably connected to each other; - the system of
levers movable slide 4 and thenon-movable frame 1 of the weapon; - the
