Description

The invention relates to weapons technology, and in particular to devices that increase accuracy, and is intended for use in small arms for combat, sports and hunting purposes.

The main condition for accurate shooting is the need for precise aiming, which is possible only when maintaining the position of the weapon at the moment of pulling the trigger and the shot.

It is possible to reduce the oscillations of the weapon if the arrow support for the shooter’s aiming and shooting is located near the fore-end, therefore, to increase the accuracy of aiming, folding handles mounted on the fore-end forearm in the combat position and horizontally in the stowed position were used. When the shooter grabs the handle vertically located at the fore-end, the shooter's hand occupies a natural position, providing a reliable grip and less weapon mobility when shooting.

Known folding handle for small arms containing a fork, an axis with a spring, the base of the hinge with a clamping screw and recesses to accommodate the spring clips (Utility Model Patent No. 55114, published on July 27, 2006).

This well-known handle is attached to the forearm with a Picatinny rail, which allows not to increase the dimensions and mass of the small arms as a whole, contributing to a more ergonomic holding of the weapon in the shooter's hand and its most accurate aiming, which reduces the shooter's physiological effect on aiming accuracy, and, moreover, this the handle is capable of folding, so it does not require time for its removal and subsequent installation.

The disadvantages of such a handle are the impossibility of using it for weapons with a standard handguard that does not contain a guide for fixing the base of the folding handle, copying the guide of the Picatinny rail, as well as the inability to use this handle on weapons with a grenade launcher, because its mount is intended only for full-time fore-end.

In addition, the installation of such a handle on a weapon with high dynamics determines its fragility due to the lack of reliable connection of its base with the mounting surface of the forend, and the use of spring-loaded components in the design complicates it and requires additional time for systematic maintenance.

At the same time, the use of a clamping screw for attaching the base of the handle to the forend guide and the need for an additional tool for this eliminates the rapid replacement of the handle in the field, and the U-shaped shape of this handle is inconvenient for holding the weapon.

Closest to the claimed invention is a folding handle for small arms, containing a holding handle on a weapon forearm base; axis connected with it; handle body indirectly interacting with the base; thrust coaxially located inside it with the possibility of axial movement, pivotally connected to the axle shaft; and made with the possibility of covering the half-axis of the sleeve with a lateral slot for fixing the handle in the stowed position by pulling the traction through the slot of the sleeve from the vertical combat position to the horizontal stowed position corresponding to the position of the axis of the hinge assembly connecting the traction with the half-shaft F41A 11/04, F41C 23/00 publ. 07.27.06.).

This folding handle, which is closest to the claimed invention, is more convenient to hold in the hand due to the round shape of the handle body compared to the above known one and has increased reliability when it is mounted on a weapon with high dynamics due to the completion of its base and body with reinforcing elements capable of dampen impacts, as well as through the use of 2 clamping screws for attaching the base of the handle to the forend guide, instead of one, as in the above known handle.

The disadvantages of this handle, which is closest to the claimed invention, as well as the one given above, are the inability to use it for weapons with a standard handguard that does not contain a guide for fixing the base of the folding handle that copies the Picatinny rail guide, as well as the inability to use this handle on weapons with a grenade launcher, as its mount is intended only for full-time fore-end. In addition, the installation of such a handle on a weapon with high dynamics determines its fragility due to the lack of reliable connection of its base with the mounting surface of the forend, and the use of spring-loaded components in the design complicates it and requires additional time for systematic maintenance. Also, the use of clamping screws for fastening the base of the handle to the forend guide and the need for an additional tool for this eliminates the rapid replacement of the handle in the field.

The purpose of the invention is the creation of a folding handle for small arms with a standard handguard of reliable design.

The technical result from the use of the present invention is to ensure the reliability of a folding handle for small arms with a standard forearm by creating its optimally simple design and reliable communication between its parts and a weapon forearm.

This is achieved by the fact that in the folding handle for small arms with a standard forend, containing the base holding the handle on the arm forearm, the axis connected to it, the handle body indirectly interacting with the base, coaxially located inside it with the possibility of axial movement of the rod pivotally connected to the axis, and made with the possibility of covering the axis of the sleeve with a side slot for fixing the handle in the stowed position by pulling traction through the slot of the sleeve from a vertical combat position in the mountains the horizontal stowed position corresponding to the axis position of the hinge unit connecting the rod to the semi-axis, the axis of the handle is integral with the horizontal shelf at its free end, and the rod and the handle body are made in the form of a threaded pair: a rod in the form of a screw and a handle body screwed onto it, and the base of the handle is made of 2 axisymmetric, counter-mounted brackets on the forearm with the possibility of full coverage of their outer surface, each with its shank in the form of a half-cylinder located above m horizontally oriented bore in the body of the brackets, assembled with their shanks to form a hollow cylinder with a lodgement of docked bores, and the sleeve is made with the possibility of free coverage of the hollow cylinder of the docked shanks of the base brackets and installed separately from the housing with the possibility of guaranteed pressing it to the base of the brackets provided by its threaded connection with the rod, while the semi-axis of the handle assembly is installed in the hollow cylinder from the docked shanks of the brackets with the possibility of placing its horizontal shelf in their lodgement of docked bores.

The manufacture of at least one of the brackets of the base of the handle with the possibility of mounting on its outer side surface a guide that copies the guide of the Picatinny rail for subsequent fastening to it a device of a certain functional purpose, for example a flashlight, allows you to expand the operational capabilities of the handle as a whole.

The implementation of the elements holding the base of the brackets on the weapon forend, with the possibility of installing on them the mounting straps of the collimator sight, improves the fighting characteristics of the handle by providing the shooter with a high aiming speed.

The invention is illustrated by drawings, presented in the figures:

Folding handle for small arms with a standard forearm contains a holding handle on the arm forearm (not shown) base 1 (Fig. 1, 2 and 7); connected to the base 1 axis 2 (Fig. 2 and 6) with a horizontal shelf 3 at one end; indirectly interacting with the base 1, the housing of the handle 4 (Fig. 1, 2 and 7); located inside the housing 4 with the possibility of axial movement of the rod 5 (Fig. 2 and 6) in the form of a screw, pivotally connected to the axis 2 by a pivot axis 6; and a sleeve 7 (Figs. 1, 2, and 7) with a side slot 8 in its body for withdrawing the rod 5 from a vertical combat position to a horizontal stowed position corresponding to the position of the axis 6 of the hinge assembly connecting the rod 5 with the axle shaft 2.

The base of the handle 1 (Fig. 1, 2, 3, 4 and 7) consists of 2 axisymmetric, opposite mounted on the forend (not shown) staples 9 and 10 with the possibility of full coverage of their outer surface and holding on it, each with with its shank 11 and 12 in the form of a hollow half cylinder with a horizontally oriented U-shaped bore 13 and 14 in the body. Both brackets 9 (Figs. 3 and 5) and 10 (Fig. 4) are assembled together with their shanks 11 and 12 to form a hollow cylinder spanning the half shaft 3 with a lodgement of joined bores 13 and 14, in which a horizontal shelf 3 of the half shaft 2 is installed.

The housing of the handle 4 (Fig. 1, 2 and 7) is screwed onto the rod 5 with the formation of a threaded pair assembled by them.

In the combat position, the assembly of the handle parts: base 1, half shaft 2, rod 5, sleeve 7 and body 4 are located on the same vertical axis of symmetry and the end face of the body 4 is pressed against the free end of the sleeve 7.

On the outer side surface of the bracket 9 (Fig. 3) of the base 1 of the handle, a guide 15 is mounted that copies the Picatinny rail for fixing a device of a certain functional purpose, for example, a lamp (not shown).

On the elements 16 and 17 (Fig. 2) of the brackets 9 and 10 of the base 1, a mounting bracket for the collimator sight 18 is installed.

The assembly and installation of the folding handle on a small arms with a standard forearm is as follows.

First, the axle shaft 2 is connected with the rod 5 by a hinge assembly with the axis 6. Then, brackets 9 and 10 are mounted on the opposite side surfaces of the forend (not shown), joining their shanks 11 and 12 with the formation of a hollow cylinder with a lodgement of docked bores 13 and 14. Holding a hollow cylinder from the joined shanks 11 and 12 in the hand, into it are inserted the interconnected half shaft 2 with a thrust of 5 until the horizontal flange 3 of the half shaft 2 rests into a lodgement of U-shaped bores 13 and 14. Then put the sleeve 7 on the free end of the thrust for 5 s axle shaft 2 until the end stop of the sleeve 7 into the outer surface of the base 1 of the brackets 9 and 10, while observing that the slot 8 of the sleeve 7 is located in the region of the hinge assembly, and its axis 6 is perpendicular to the axis of the sleeve 7.

After that, the handle housing 4 is screwed onto the rod 6 until its end is pressed tightly against the free end of the sleeve 7, thereby guaranteeing, by means of a threaded connection of the housing 4 with the rod 5, that all parts of the handle are securely joined together.

If necessary, guides 15 are copied to one or two outer side surfaces of the brackets, which copy the guide of the Picatinny rail, for subsequent fastening to it fixtures of a certain functional purpose, for example, a flashlight.

Also, if necessary, on the elements 16 and 17 of the brackets 9 and 10 of the base 1, holding it on the arm forearm, set the mounting bracket of the collimator sight 18.

Assembled in this way and mounted on small arms with a standard handguard, the handle is in a combat position.

To set this handle in the stowed position (Fig. 7), screw the housing 4 from the rod 5 to such a position that it can be moved its rod 5 through the slot 8 of the sleeve 7 to a horizontal position corresponding to the axis 6 of the hinge assembly connecting the axle shaft 2 with the rod 5. After that, screw the housing 4 until the end of the end stops against the surface of the sleeve 7, closing it with its slot 8 and guaranteeing them to be tightly pressed against each other due to the threaded connection of the housing 4 with the rod 5, reliably joining together all the handle parts.

The proposed folding handle for small arms with a standard handguard with a combination of its essential features allows you to create an optimally simple and reliable design of a folding handle for use on weapons with a standard handguard due to the combination of all its distinctive essential features, namely: the manufacture of the shaft of the handle along with a horizontal shelf at its free end, the manufacture of a rod and a handle body in the form of a threaded pair: a rod in the form of a screw and a handle body screwed onto it, and made I am the base of the handle of 2 axisymmetric, counter-mounted brackets on the forearm with the possibility of full coverage of their outer surface, each with its shank in the form of a half cylinder with a horizontally oriented bore in the body of the bracket, assembled with its own shanks to form of them a hollow cylinder with a lodgement of docked bores, as well as the manufacture of the sleeve with the possibility of free coverage of the hollow cylinder of the docked shanks of the brackets of the base and its installation about separately from the body with the possibility of guaranteed clamping to the base of the brackets, provided by its threaded connection with the rod, and the location of the semi-axis of the handle in the hollow cylinder from the docked shanks of the brackets so that its horizontal shelf was installed in the lodgement of brackets from the docked bores.

The folding handle for small arms with a standard forearm has successfully passed the tests and is currently preparing for production for use on small arms with a standard forearm.
