Description

Pistol

The invention relates to a pistol which is suitable for military use, e.g. military or police, and on the civilian side, e.g.

Generally, gun structures are such that when disassembled, at least 4 pieces of various parts are removed for maintenance and inspection, some of which may easily be lost in small size, it has been found necessary to develop a structure which does not present the problem.

Generally, pistols using powerful military cartridges are based on their principle of short-barreled weaponry, with the barrel of the barrel locked to each other at the time the cartridge is fired.

Such a structure requires that the barrel of the weapon be able to move in the weapon structure both longitudinally and / or vertically and must be removed from the weapon as a highly movable part each time it is unloaded.

Typically, the following parts will separate from the pistols when disassembled for maintenance:

Frame, slide / shutter, barrel, slide return spring and return spring spindle.

Instead, the operating principles of the weapon subject to the invention may be based on two weapon engineering structures, which are a mass barrier and a gas piston structure.

In both configurations, the barrel of the gun does not move at all and allows the barrel to be attached to the gun body in this case by a hinge connection, whereby a generally detachable barrel can be left on the body.

In addition to this, generally the guns are released when the skid return spring and spring guide spindle are disassembled. In the pistol which is the subject of the invention, these parts are not detached either, but they are detached with the slide as a subassembly, which also includes the central part of the invention, i.e. the release latch.

In other words, the pistol which is the subject of the invention is disassembled during normal maintenance into two subassemblies, the body and the barrel hinged on its axis, and a slide with a longitudinal guide attached to the unlatching structure.

A distinctive feature of the pistol is its unlocking structure, which comprises parts of a latch piece (1), a slide retraction spring (14) and a spring guide spindle (6), which may be retained when necessary as a subassembly in the gun barrel / slider (2).

The unlocking structure allows quick and easy disassembly of the weapon structure for maintenance and inspection.

This design allows the weapon to be disassembled, if necessary, into only two easy-to-handle, large-sized subassemblies, allowing extremely quick and easy maintenance / inspection of the weapon.

The unlocking structure is part of the weapon's body structure, holding the parts of the weapon together when the weapon is assembled, thus constituting a significant structural solution within the weapon.

In the following, the basic techniques and operating principles of the pistol in question are based on numerous and commonly used weapon structures for which patents are either obsolete or could not be patented as commonly used structures, whereas the central area of the invention is the unlocking structure of the pistol body.

Basic technology and principle of operation of the pistol in question:

Basic gun technology is very traditional and commonly used in guns.

The basic technique of the pistol is built around the body (3), comprising a slide (2), or barrel of the weapon, which moves along the top of the body by a conductor connection in the direction of the barrel.

The pistol body includes the gun's trigger components (not shown) and, when loading the weapon, into the cartridge mount (not shown).

The gun is operated by holding the handle in the transverse / vertical position of the gun body in the transverse / vertical position of the barrel and loading it by inserting the cartridge magazine into the magazine compartment (not shown), then pulling the gun slider back to its front position. the gun is ready to shoot.

The weapon is fired from the trigger portion of the trigger mechanism on the front of the handle portion, which is operated with a finger and pulled toward the handle.

The weapon's firing capability is removed by removing the cartridge magazine from the inside of the handle and pulling the slide to the rear position to remove the non-fired cartridge from the barrel.

The basic principle of the pistol is self-loading / semi-automatic, ie when firing the weapon technology utilizes a small amount of energy released from the ammunition, tune the gun's firing mechanism and load a new cartridge into the barrel of the weapon.

The central part of the pistol's self-loading / semi-automatic function is the slide (2), the barrel of the weapon which first fires the firing mechanism, removes the fired cartridge from the weapon and fires (3) from the existing spring loaded cartridge magazine to the new cartridge gun barrel (4), the gun is again loaded ready to shoot.

The self-loading / semiautomatic operation of the pistol in question may be based on two weapon-technical structures, namely a mass barrier structure and a gas piston structure.

In the mass barrier structure, the mass of the freely moving slide and the slide's return spring store a small amount of energy generated from the cartridge, tune and charge the weapon in the basic operating principle.

In the gas piston structure, the slide has a separate locking piece which locks into the barrel and which is locked and unlocked by a slide in a direction parallel to the barrel line. The lock is locked in the barrel at the time of firing and stays closed until the powder gas from the bore in the barrel pushes the gas piston and slider in contact with the slider, unlocking the lock, whereupon the weapon's machinery continues to mass-tune and reload.

Gas piston technology is necessary when using powerful cartridges because mass sealing would render the structure impractically heavy, the mass of the closure and the resistance of the slide return spring increase as the cartridge power increases.

3

If the cartridge is too strong in relation to the mass of the barrel and the resistance of the slider's return spring will cause the cartridge to rupture and can be injured by powdered gas directed at the shooter, the barrel speeds will become too high and disrupt the weapon technology.

The purpose of the gas pellet technology is to extend the condensation time of the cartridge's powder gases in the barrel of the weapon so that the weapon's machinery does not receive too much energy from the cartridge and is thus not damaged. The operating principles described above are thus generally used in weapons and thus do not make the weapon in question abnormal in structure.

Also used structures, though not so common, include a barrel (4) hinged from the front end of the gun to the bore of the gun (4), which projects from the rear to the bore in the slide (2) to form a barrel centered barrel.

Patentable design and function of the weapon concerned:

The pistol in question has been developed with a disarming mechanism which allows for a partial quick and easy disassembly of the weapon structure for maintenance and inspection, which allows for less detachable parts of the weapon compared to conventional structures and which makes the weapon structure characteristic.

How it works:

Disassembly of the weapon can be done as needed.

When disassembling the release latch (1) with the operating lugs on both sides of the gun, push it forward in the direction of the barrel centerline until the frame locking wires (10) end to release the release latch (1) and slide (2) and rear barrel (4). apart from the body, on the barrel front hinge joint.

The slide can then be pulled back around the barrel's rear end, whereby the slide and the unlocking catch on the guides on its underside are released from the gun.

At this first stage, the weapon is basic serviceable and verifiable, consisting of only two large, easy-to-handle subassemblies, namely the slide and unloader assembly and the barrel and frame assembly.

If it is still necessary to disassemble the gun further with the release latch including the latch piece (1), the slide return spring (14) and the spring spindle (6) can be detached from the lower slide guides (16) by pushing the release latch forward lifts off the underside of the skate.

If the gun has a gas piston design, a separate locking piece can be removed from the inside of the slide at this point, the mass barreled gun does not have a separate locking piece.

The barrel can also be removed from the body by pushing the shaft at the front end of the barrel out of its bore, thereby opening the hinge connection between the barrel and the body and lifting the barrel out of the body.

This gun does not normally require the gun to be dismantled.

Discharge latch technology and operation:

In principle, the release latch (1) locks the slide (2) onto the body (3), also forming a lock for the hinge connection of the body (3), the barrel (4) and the barrel (7).

The disassembly assembly comprises a disassembly piece (1), a slide return spring (14) and a return spring spindle (6) which together lock the slide (2), i.e. the barrel of the weapon, and the barrel hinged from the front end to the body.

The unloading latch has barrel center guides on the upper (8) and lower (9) surfaces which correspond to the barrel center line guides (16) and the barrel center barrel guides (10) on the lower surface of the slide.

When unloading the gun, push the unlocking latch (1) forward along the barrel centerline until the frame locking wires (10) terminate, releasing the connection between the unloading latch and the frame so that the slide (2) and barrel (4) can be pivoted away from the frame. It is also characteristic of the structure that the slide locking guides (16) are longer than the body locking guides (10), thus, when unlocking the gun, the locking wire connection between the release latch (1) and the slide (2) is retained. and accelerate.

The release latch (1) can be detached from the slide (2) if desired by pushing the release latch forward in the direction of the barrel center until the slide locking guides (16) end and the conductor connection opens and the release latch can be lifted off the underside of the slide.

With the unloading latch (1) attached to the slide (2), the skid's skirt guides (5) limit the rearward movement of the unloading barrel barrel.

The pistol is also characterized by a locking structure between the barrel shaft (7) and the spindle return spring spindle (6) of the slide release assembly.

The locking device consists of a locking groove (15) rotating about the center line of the shaft (7), which, when assembled, protrudes the front end of the spindle return spring spindle (6) transversely to the centerline of the shaft.

When the gun is unloaded, the slider return spring spindle (6) leaving the slider (2) releases the locking connection and, if so desired, the barrel shaft (7) can be removed from the bore in the body and barrel to release the barrel from the body.
