Description

FIELD OF TECHNOLOGY

The invention relates to firearms in general and, in particular, to rifle stocks and accessories to them.

BACKGROUND

Despite the long history of firearms and continuous research and development aimed at improving the characteristics and ergonomics, the shape and configuration of the stocks for a typical modern sports rifle are comparable to the stocks of similar weapons that were used many decades ago. Significant deviations from the original form of the rifle box with its forearm, pistol grip, cheek and butt in hunting / sporting weapons are rare and not even characteristic of army weapons.

Partly due to the conservative attitude of the shooters to the adoption of radical weapons innovations and partly due to the prevailing view that all the possible advantages and improvements in the ergonomics of the lodge have already been studied, the main R&D in the field of weapons is limited mainly to improvements in materials, ammunition, reliability and ease of manufacture. This conservative attitude is characteristic even for shooting positions occupied by the shooter. Indeed, the instructions on the shooting technique are often limited to the classic "positions": shooting from a prone position, sitting, from a knee and standing.

However, it should be noted that in these and other positions for firing, stocks of weapons of a conventional design do not always allow the shooter to conveniently and efficiently hold the weapon.

It is safe to say that in the foreseeable future, conventional rifle ammunition will continue to be used. Own characteristics of the length of the barrel and the weight of such rifles inevitably require the shooter to support the weapon with one hand in the fore-end region and pull the trigger with the other. In different situations, support by the hand is supplemented and / or replaced by the use of supports, either attached to the weapon itself, for example, bipods (bipod bipod), or external, for example, a fence post, etc.

Ergonomic shortcomings of conventional rifle stock designs led to the development of various modifications of the stock and / or attachments to it, which are used in many target and sniper rifles. By definition, a criterion of accuracy is a very important performance criterion for these rifles. In order to achieve the greatest accuracy of fire, the shooter must maintain the most ergonomically effective, convenient and repeatable position when shooting.

Some target rifles in the fore-end area have adjustable handles with which the user supports the rifle with the hand that does not press the trigger.

Such devices are often adjustable in the vertical and / or horizontal plane. However, they are inconvenient and cumbersome for any sports and / or military use. Ergonomic problems are partially, but not completely resolved, using lodges with a thumb hole, adjustable cheeks and upper edges of the butt, as well as adjustable butt plates of the butt.

Moreover, many gunners, army and civilians, require or wish to use weapons accessories for optional attachment to weapons. We are talking about accessories such as two-legged, one-legged bipod, additional handles, swivels, sights, spare shops, etc. Conventional weapon boxes do not allow efficient attachment of such accessories without affecting the functionality or practicality of the weapon and / or this equipment.

Therefore, there is a need for an easily adaptable, practical box that provides improved ergonomic capabilities for the shooter in a wide variety of shooting positions and at the same time improves the usability and / or effectiveness of the various weapons that the shooter wishes to use.

One of the objectives of the present invention is to eliminate these drawbacks, or at least provide the public with a choice.

Other aspects and advantages of the present invention will become apparent from the following description, which is given here for illustrative purposes only.

SUMMARY OF THE INVENTION

According to one aspect of the present invention, there is provided a weapon bed adapted to accommodate a warhead including a barrel and a receiver connected to the barrel, said bed having a first pistol grip located between the first forearm located in front and the butt located in back, so that in the assembly with the specified warhead, the specified barrel is located next to the specified first forearm closer to the front end, characterized in that the said bed also has an elongated element of the lower second chain vyu, spatially separated from the specified box and located below it, at least in part of its length in a place located on the first pistol grip or below it, and passing to a distance equal to or less than the distance between the end of the barrel, far for the specified receiver and the indicated rear end of the specified butt, and the specified second forend is attached to the specified box in two or more attachment points, and at the specified box the second forend at one or more of the indicated attachment points does not form a whole with the decree Anna box.

It is understood that references to the orientation of the lodge according to this invention and its parts throughout the description are given only for explanation and are given for the case of using the proposed lodge in the normal position for standing firing, and parts of the proposed lodge next to the user are referred to as such from the "rear end" , and those parts of the proposed box that are removed from the user are referred to as those closer to the "front end".

References to places or positions of the invention and its parts in the vertical plane are made relative to the user aiming from the rifle containing the present invention in the usual way in the horizontal plane. However, the references cited do not limit the application of the present invention to one particular direction and / or one particular orientation.

The expression "forms a whole", used in connection with the fastening of the second forend to the lower forearm, refers to a manufacturing method, as a result of which the parts are not removable during the normal / intended use of the weapon, or do not separate without damaging the stock, and / or means continuous, uniform, uniform non-breakable, non-segmented, non-articulated, fixed, non-slip, non-removable, non-releasable design.

When constructing a box with one or more attachment points that do not form a single unit, in addition to the improved positions during shooting and ergonomics of the weapon, many additional features are described below. These features include variants of known cyclic weapon mechanisms (e.g., weapons with a pump-action shutter), devices for increasing stability (biped attachment, side racks, etc.), attachment of magazines / weapon accessories and weapons storage positions.

In the text of the present description, the term "pistol grip" means any handle adapted to or suitable for the user to be able to hold it with the entire brush or part thereof.

The terms “weapons” and “rifle” used in the text of this description include assault rifles, automatic and semi-automatic weapons, hunting and sports weapons, self-defense weapons, sniper rifles and rifles for target shooting, smoothbore weapons, etc.

References to the free hand, free shoulder, free hand, etc. refer to parts of the hand that are not used to lower the trigger.

In one aspect of the present invention, said second forend extends substantially parallel to said trunk. In other embodiments, the implementation of the specified second forend in the direction of the front end has a slope up or down.

In yet another aspect of the present invention, a portion of the second forend between the first pistol grip and the rear end of the stock in the direction of the rear end slopes up or down.

The specified second handguard can be attached to the bed in a variety of configurations, including mounting with attachment points on the specified first pistol grip and / or the specified first handguard.

The attachment points of the second forend may alternatively be located on the indicated buttstock in combination with the attachment to the first forend and / or first pistol grip.

In yet another aspect of the present invention, at least one attachment point of said second forend is attached to said first forearm with one or more fasteners extending (s) downward from the first forend.

In one embodiment of the invention, said fastener is a handle, preferably in the form of a second pistol handle.

The presence of the lower second fore-end gives a number of advantages, especially with respect to the shooting positions, which are impossible with the known designs of the weapon box. Even in positions when shooting using various supports (one-legged bipods, two-legs, tripods, etc.), almost all of these positions require some form of additional support for the gunner’s body. Typically, the shooter uses a free hand / hand for this, although a knee and even the shooter's body can be used.

In the standing position, the configuration and dimensions of the usual rifle stocks do not allow the user to freely hold the usual (first) upper handguard, while simultaneously using the torso to support the shooter's free elbow. This is mainly due to the fact that the lower side of a conventional forearm is not sufficiently separated from the trunk in a vertical plane to make using the abutment of the elbow in the torso ergonomically or practically possible.

In the provisions for firing from a knee or sitting, the indicated position of the lower surface of the first forearm does not allow the practical use of the shooter's knees as a direct support when firing.

These disadvantages are eliminated by adding the lower second forearm in a position well below the position of the first forearm. The lower second handguard can be used as a direct support in the position for shooting from the knee or while sitting and, in addition, as the contact surface for the free hand of the shooter to rest the elbow of the free hand on the thigh or upper part of the torso for additional support.

The presence of the lower second fore-end also gives advantages in the position for shooting while lying down, since in this case the fingers, palm and fist can be used to adjust the weapon in height and as its support.

In addition to these and other provisions, possible using the present invention, it does not interfere with occupying the usual positions for firing or using conventional racks and clamps for weapons.

It would be very useful if the embodiment of the present invention with a continuous lower second forearm extending between the first pistol grip or butt and the front end of the upper first forearm provides some practical advantages that would prevent tangling in the undergrowth or other obstacles, as well as prevent incidents that have to be encountered while hunting or during hostilities.

However, it should be noted that the lower second forend does not have to be continuous only to provide support when firing, as described above.

Therefore, in one embodiment of the present invention, said lower second forend is discontinuous at one or more points between the butt and / or first pistol grip and the front end of the first forend towards the far end of the barrel, and in an alternative embodiment of the present invention, said lower the second forearm extends continuously from the specified butt and / or the specified first pistol grip towards the front edge of the first forearm.

Small arms, especially long-barreled ones, such as rifles and the like, are relatively bulky and heavy equipment, which are often worn for a much longer time compared with the time spent on the actual shooting. Arms belts of various shapes are well-known means of solving such problems, which inevitably entails the use of flexible strips of material. The use of these strips can in principle lead to the fact that the shooter and / or his equipment will become entangled in them or they themselves will become entangled in the surrounding objects. Further, gun belts and swivels for them can tear (break) or require periodic care / adjustment for proper functioning.

In yet another embodiment of the invention, said butt at least partially limits a first opening configured to include a user's shoulder and a weapon hanging on his shoulder, i.e. served as a shoulder gun belt.

According to another embodiment of the present invention, said lower second fore-end at least partially limits a second opening configured so that the user's shoulder enters and the weapon hangs on the shoulder, i.e. served as a shoulder gun belt.

In other aspects of the present invention, said fastenings of said second forend to any (any) of said butt, first pistol grip, second pistol grip or first forend, in addition to a fixed or rigid mount, can be adjustable, removable, rotatable and / or sliding mounts, or a combination thereof.

The mounting methods described above can be combined to produce a wide variety of properties, for example, an angle-adjustable cross member, in particular a second pistol grip. In such an embodiment, the second pistol grip can be pivotally attached to the first forearm and slide attached to the second forearm with an adjustable sliding configuration. With this solution, the vertical angle of the second pistol grip can be changed by sliding the lower end of the second pistol grip to the desired position and then fixing it in this position in an appropriate way, for example, with a screw, protrusions, etc.

It would be very useful if the sliding mount could take several forms, for example, a mount with a transverse pin / screw, placed in the hole with slots in the lower second forend. Alternatively, the second pistol grip can be pivotally attached to a portion of the lower second forearm, which in turn is telescopically attached to the rest of the lower second forearm.

The use of the telescopic and / or sliding parts of the lower second forearm is intended to close one or more gaps between the parts of the lower second forearm. For example, an opening configured so that elongated magazines can be used, when using truncated magazines, it is possible to overlap with the sliding / telescopic part of the lower second forearm.

According to another aspect of the present invention, said lower second forend and / or said butt has (have) one or more support elements pivotally attached to the lower surface of the lower second forend and / or butt, which can be turned outward from the stock outward in the transverse direction to create support for the stock in an almost vertical position relative to the horizontal when installed on a solid or semi-solid surface.

According to another aspect of the present invention, the lower second forend is removably attached to the bed at the first end, and can be rotated at the second, and the lower second forend can be turned down relative to the specified second end and used as a support for weapons when mounted on a hard surface or on an auxiliary element worn by the user, for example, a belt or scabbard.

Automatic reloading operations are known for almost all types of small arms. However, manual reloading is still preserved and even preferable for some types of weapons, for example, for weapons with a pump action shutter mechanism, such as, say, shotguns, grenade launchers, etc. Manual reloading mechanisms are usually lighter, more reliable, and less complex than their automatic counterparts.

The use of the proposed second lower fore-end according to this invention provides an additional increase in reliability and efficiency. In typical shotguns with a pump-action shutter mechanism, the neck of the lodge or shutter is used to cyclically repeat the charging / ejection of cartridges. The requirement for a specific form of such a sliding mount creates structural difficulties when using the front pistol grip mount as a shutter handle. Any transverse or torsional forces exerted on the pistol shutter handle can cause malfunction or damage to the pump mechanism. When a second lower fore-end is added, the lateral stiffness of the pistol shutter grip increases.

The pump action mechanism can be used in several configurations. The attachment of the second pistol grip to the second lower forearm is not a rigid attachment to the second lower forearm and / or the first forearm, and this non-rigid attachment can be selected from the group consisting of articulated, sliding, swivel, removable mounts and / or any combination thereof.

The effectiveness and applicability of this invention can be shown on the example of a box with a second lower forearm with attachment points to the first pistol grip and to the upper first forearm of the second pistol grip. Such a bed can have three main attachment points: the base of the first pistol grip (OPR), the base of the second pistol grip (OVPR) and the top of the second pistol grip (GDPR). Among the possible configurations of these attachment points are the following:

GDPR can be performed as

i) a fixed hinge that can rotate (relative to a fixed pivot point) in a vertical plane parallel to the barrel. Thus, the angle of the pistol grip can be changed at the request of the user by changing the angle of inclination;

ii) a removable hinge with the same properties as the fixed hinge described above, with the additional possibility of easy removal from the stock of the second pistol grip;

iii) a sliding hinge, which can also be lockable or removable and, in addition to the properties of the removable hinge, can also change the distance of the second pistol grip from the shooter;

iv) articulated pump (removable or fixed), where the hinge mount is fixed with respect to the pump / shutter arm for cyclic repetition of the action of loading / ejecting cartridges;

v) a sliding hinge of the pump, combining the properties of the hinge pump described above and the sliding hinge described above.

It would be very useful if the sliding and / or rotational movement in the above joints could be limited in size or completely eliminated with the help of appropriate adjusting stops, stops, screws, protrusions, etc. at the request of users.

OPPR can, of course, be performed both as a non-hinged, non-sliding mount either removable or integral with the fixed or sliding first handguard of the pump mechanism.

Locking the pump-action shutter also serves as an additional safety measure to prevent accidental or unauthorized use. Such locking can be easily carried out in many different ways, for example, simply using a padlock, the handle of which is inserted into the hole in the shutter guide in the second lower forend.

Similarly, with an approximate list of possible OVR compounds, you can perform as:

vi) forming a single fixed compound;

vii) a hinge that allows adjustment to change the tilt of the second pistol grip (in combination with a hinged or sliding GDPR), and as an axis for scissors (for example, for cutting wire) and for turning the second lower forearm when removing from any other attachment points (for example , the first pistol grip) to use it as a one-legged bipod, etc .;

viii) a removable hinge with the same properties as the hinge described above, with the additional possibility of turning the second lower forearm relative to another attachment point for use, for example, as a one-legged bipod;

ix) a simple, non-integral mount, removable for storage, but not for use in the field;

x) a hinge / series of holes (also applicable to any attachment point, including GDPR), allowing various adjustments to the distance from the pistol grip to the shooter and the inclination of the pistol grip depending on the attachment configuration used for the GDPR;

xi) an arcuate slot providing the same properties as the hinge / row of holes in paragraph (x), but without limiting the specific location of the row of holes, and which can ensure the invariance of the angle of the second lower forearm when adjusting the second pistol grip;

xii) a horizontal slot that provides another option for properties according to points (x) and (xi).

The connection described above allows you to get several configurations of the pump-action shutter mechanism, including the following:

- the usual push action, in which the used sleeve (if any) is removed by pushing back to the side of the arrow and a new cartridge is inserted forward in reverse;

- the action of pushing, proceeding in the reverse order, which can be used for underbarrel grenade launchers;

- pump action of the forend, in which the second pistol grip or other suitable fastener rotates in an arc to cyclically repeat the pump action (pushing or pushing). This ensures a previously inaccessible pump action, which is created by the action of the wrist, and not by the linear action of the hand. The geometric sequence of turning the rotational movement of the pistol grip into the linear movement of the first forend as a shutter is possible only through the use of the above-described fastening nodes (articulated, with slots, etc.) of the present invention.

And finally, OPPR connections can be performed as:

xiii) fixed, forming one unit or not forming one unit (for example, bolted) connection;

xiv) hinge, fixed or removable. As in the case of GDPR and OVPR, the hinge can be used in combination with a slot and / or several spaced holes.

The (removable) hinge allows

- remove the second lower fore-end;

- use the second lower fore-end as a lever, a support for shooting, a one-legged bipod, etc .;

- adjust the slope of the second pistol grip;

- ensure the action of the fore-end as a pump-action shutter mechanism (as described above).

Thus, the presence of a second lower forearm with at least one attachment point to the bed, which does not form a whole, provides a number of advantages described above, including the removal of the lower forearm either in the OPPR or OVPR and rotation relative to the other to obtain a one-leg support bipod for shooting or lever action for cutting a wire or the like. Further, the configuration of the entire stock allows the use of hanging / wearing devices that are impossible or impractical in the case of conventional weapons, including gun mounts located at the four corners of the weapon. This configuration is stable and allows you to carry the box as a backpack.

Due to the structural improvement provided by the present invention, the gun belt can be mounted on said first forend without causing any structural failure of the pump shutter mechanism.

It is also clear that in order to provide the advantages and signs discussed above, it is possible to redo the well-known stocks of rifles - add a second lower fore-end.

In yet another embodiment of the present invention, there is provided a method of remaking a weapon box by adding a second lower forearm as described above.

Further, a second lower forend is described, which is described above, which can be attached to an existing box.

In yet another embodiment of the present invention, there is provided a bracket for attaching a gun belt to a first forearm, covering at least partially a specified barrel.

Further, the lower second forend serves as a convenient place for attaching various equipment. The latter is preferably mounted on the upper surface of the lower second forearm so that the forearm also protects it. However, at the request of the user, these accessories / accessories can also be installed on the side of or below the lower second forend.

In yet another embodiment of the present invention, said lower second forend is configured to mount one or more weapons thereon, including bipods, additional arms, magazines, bayonets, wire cutters, communication devices, computing devices, ammunition, charging devices, rechargeable batteries, laser designators, etc.

In cases where long-barreled weapons, such as rifles, are not used by arrows, their irregular shape creates certain difficulties in terms of preventing possible damage and / or accumulation of unwanted dirt or foreign matter on or in the weapon. Such weapons can, of course, be made upright, although without a special pyramid or other convenient or suitable vertical support, this is not such a simple task, especially in the field.

Putting weapons directly on the ground is associated with obvious potential problems in terms of dirt getting into the weapons working mechanism and / or sighting optics. Weapons warehouses and workshops are undoubtedly equipped with a vise and other restraints necessary to perform work on weapons in a horizontal position. However, for many tasks, the time and effort spent putting each weapon in a vice is disproportionately large compared to the small amount of work that needs to be done.

It would be very useful if, in order for the bed to meet different functional, industrial, technological, practical, ergonomic and aesthetic requirements, various bends, curves, holes or curvatures could be provided on the lower second forend within the scope of the present invention.

Description of preferred embodiments of the invention

Returning to the drawings, in which similar parts in all the shown embodiments are denoted by the same position, Fig. 1 shows a preferred embodiment of the present invention in the form of a stock of weapons (1) adapted to accommodate a warhead (2) consisting of a barrel (3) and a receiver (4) connected to the barrel (3). The warhead (2) can be any known type of mechanism used in rifles and other long small arms, including assault rifles, sniper rifles, target rifles, hunting and sporting rifles, automatic and semi-automatic weapons, shotguns, etc.

The box itself (1) consists of the first pistol grip (5) located between the first forend (6) and the butt (7). The fore-end (6) is located closer to the front end of the rifle and adjoins the barrel (3) after attaching the box (1) to the warhead (2). Butt (7) is located at the rear end of the weapon and when firing, rests on the shoulder of the user. In addition, the bed (1) has a second lower forend (8) located on the first pistol grip (5) or lower and extending to a distance equal to or less than the distance between the distal end (3a) of the barrel (3) and the butt end (7) )

In the embodiment shown in FIG. 1, the second forend (8) extends substantially parallel to the barrel (3), although the invention is not limited to such a configuration. The lower fore-end (8) may alternatively slope up or even down from the region of the first pistol grip (5) towards the front edge of the stock.

The lower second forend (8) can be attached to the bed (1) in different configurations. In Fig. 1, the lower second forend (8) is attached to the lower end of the first pistol grip (5), the butt (7) and the front end of the first forend (6) with two fasteners extending downward from the first forend (6). At least one of the fasteners should preferably be in the form of a handle (9) in the form of a second pistol grip (10). In alternative embodiments, a single fastener (9) may be used, preferably in the form of a second pistol grip (10).

The lower second forend (8) and, optionally, one or more fasteners (9) / pistol grip (10) can be performed as an element of a specialized box (1) or, alternatively, can be mounted on a known bed, as shown in figure 2 . A second pistol grip (10) and a lower second forend (8) extending from the second pistol grip (10) to the butt end of the butt (7) are attached to the usual rifle bed (1a) - shown in Fig. 2, although it would be very useful, if the lower second forend (8) could also be attached to the first pistol grip (5).

For proper operation, the lower second handguard (8) between the fastener (9) / second pistol grip (10) and the first pistol grip (neck) (5) and / or butt (7) need not be continuous. Figure 3 shows a gap in the lower forend (8), through which, for example, you can attach / disconnect the magazine (11) to / from the warhead (2). When using shortened magazines (11), this gap can be closed (partially or completely) by the sliding or telescopic part (8a) of the lower second forend (8).

Regarding the adaptation of the present invention to stores, in particular, alternatives to the discontinuous lower second forend in FIG. 3 are shown in FIGS. 4 (a) to (c).

Figure 4 (a) shows a bottom view of a linear elongated lower second forend (8) (shown in figure 1), which can be used in combination with relatively short magazines (11).

Figure 4 (b) illustrates the lower second forend (8), curved sideways, allowing longer magazines (11) to pass vertically down past the lower second forend (8), while allowing the insertion of medium or short magazines (11) into the warhead (2) ) The lower second handguard (8) can be bent left or right (in plan) depending on whether the left-handed or right-handed shooter and with which hand he prefers to change the magazine (11).

Fig. 4 (c) illustrates an alternative to the embodiment shown in Fig. 4 (b), in which an additional elongated element (8a) is used to give the lower second forearm (8) a laterally curved shape.

The use of the lower second forend (8) provides additional firing positions that are not possible with conventional box configurations. We are talking about the provisions for shooting standing, from the knee, sitting and lying, although it should be understood that these provisions are given only as an example and that the invention is not limited to them.

When shooting from ordinary rifles from a standing position, the shooter, as a rule, should take with his free hand (not the one that pulls the trigger) the usual first forend (6) to support the weapon during aiming and shooting. This firing position (shown in FIG. 5) can still be used with the stock (1) of the present invention.

However, when using the proposed lodge, alternative positions for standing shooting are also possible. Figure 6 shows a user who, with his free hand, supports the lower second fore-end (8) from below and at the same time, for additional stability, rests the elbow of the free hand in the thigh / upper body.

Variants of the standing position include a standing position in which the shooter with his free hand holds the second pistol grip (10) (or other appropriate mounting element (9)) (Fig. 7). Alternatively, the shooter can hold alternative holders in his free hand, for example, a bipod leg (12) attached to the bed (2) or a special handle (13) attached to the first pistol grip (5), as shown in Figs. 8 and 9, respectively .

The present invention also makes it possible to use a previously unused shooting position in which the shooter supports the lower second fore-end (8) on the bend of the elbow of the free hand (13) and uses the brush (15) of the free hand (16) to hold the gun or clothing of the shooter on the opposite shoulder (fourteen). This position is reminiscent of a "hug" and can be used in positions for shooting while sitting and from the knee, as shown in Figs. 11 and 12, respectively.

With particular regard to firing from a sitting position, the present invention provides additional advantages with respect to supporting a weapon during aiming and shooting. 11 illustrates the use of the hug position described above with reference to FIG. 10, with the difference that the lower second fore-end (8) rests on the forward knee (17) of the arrow, i.e. the knee closest to the front end of the trunk (3). Alternatively, to support one or both elbows (13), one or both knees (17, 18) can be used and / or the lower second fore-end (8) can be supported directly on the forward knee.

FIG. 13 also shows the shooter in the sitting position, as in FIG. 11, but in this case, the shooter holds the second pistol grip (10) with his free hand (15).

Variants of this position include a sitting position with legs apart (as shown), a sitting position with knees (17, 18) apart, but with feet together, and a sitting position with legs crossed. The “classic” sitting position with an elbow on each knee and with a free hand (15) on the first forend (6) also belongs to these options.

On Fig and 14-16 shows the shooter in position for shooting from the knee. On Fig illustrates the position for shooting "hugging" (described above), in which the elbow (13) of the free hand rests on the forward knee of the arrow. In Fig. 14, the arrow rests the elbow (13) of the free hand on the forward knee (17), and with the free hand (15) supports the lower second forend (8).

Alternatively, the lower second forend (8) can be supported directly on the forward knee (17) of the arrow, and with your free hand hold the second pistol grip (10), as shown in FIG. In this case, it is possible to perform height adjustment without violating stability by inserting the free hand (15) arrow (clenched fist, open hand or just fingers) between the lower second forend (8) and the knee (17) pointing forward, as shown in Fig. 16 .

The same method of placing the part of the free hand (15) arrow for support under the lower handguard (8) (shown in enlarged view in figa) can be used in the position for shooting lying, as shown in Fig.17. The configuration of the part of the lower second forend (8) behind the first pistol grip (5) with an upward slope allows the shooter in the prone position to shoot more easily to adjust the height of all weapons. It is clear that the shooter can alternatively support the box (1), holding in his hand a second pistol grip (10) or upper forend (6).

Hinging the lower second forearm (8) to the lower end of the second pistol grip (10) / fastener (9) or the first pistol grip (5) and the removable fastening of the other end of the lower second forearm (8) allows you to deploy the lower second forearm (8), to get a one-legged support bipod. On Fig shows the shooter in the position for shooting sitting, using the lower second forend (8) as a one-legged bipod, pivotally attached to the first pistol grip (5). The maximum vertical height of such a one-legged bipod, of course, is determined by the length of the unfolded part of the lower second forend (8). A smaller vertical height can be achieved by securing the one-legged bipod / lower second forend (8) at an acute angle to the ground. Longer lengths can be achieved with an elongated configuration of the second forend (8), for example, with its telescopic design.

Further embodiments of the present invention include non-removable means of supporting a weapon when it is worn in a manner directly comparable to using a conventional gun belt. Instead of using a flexible piece of material attached to two (or more) fixed points on the bed (1), the bed itself is configured as a gun belt.

On Fig (a) and 19 (b) shows a shooter using both versions of such a "gun belt lodge." Figures 1 and 19 (a) show the rear "gun belt of the stock" formed by the first hole bounded by the parts of the stock (7), the lower second forend (8) and the first pistol grip (5), through which the shooter can insert a hand to the shoulder and put a weapon on him. To fit the normally rounded contours of the human shoulder, the rear part (19) of the indicated first hole formed by the butt (7) and part (20) of the lower second handguard (8) behind the first pistol grip (5) is optionally configured with a convex profile. For further convenience to the user, soft material may be provided around the perimeter of said first hole.

Another "gun belt box" can optionally be performed on the front end of the box in the form of a second hole bounded by the lower second forearm (8), the second pistol grip (10) and the upper forearm (6). Unlike the rear “gun belt of the box”, when carrying a weapon on the front “gun belt of the box” (as shown in FIG. 19b), the weapon is directed downward. In the case of a box of the usual construction (1a), redone with the addition of the lower second forend (8) (as shown in figure 2), using the rear “gun belt” is impractical, although the front one can be provided if desired.

In other preferred embodiments, convenient methods of fastening and wearing gun accessories on a bed (1) are provided. These accessories can be very different and can include bipods, extra handles, magazines, bayonets, wire cutters, communication devices, grenade launchers, etc. The enclosing properties of the solid lower second forend (8) attached to the first pistol grip (5) and the second pistol grip (10) provide a safer way to place these accessories on the weapon itself than is possible with conventional stock configurations.

Figure 1 illustrates the fastening of the bipod (21) between the upper first and lower second forend (6, 8), in which the free ends of both legs in order to avoid accidental release are placed in specially made for this groove.

FIG. 20 illustrates another embodiment in which additional stores (22) are placed on the upper side of the lower second fore-end (8). According to one embodiment, the device for fixing additional magazines (22) is configured in such a way that until the magazine (11) inserted into the warhead is removed, it is impossible to remove any additional magazine (22).

Fig. 21 illustrates the fastening of a bayonet (23) to the lower second forearm (8) using its sheath (24) placed in an inclined slot (25) in the second forend (8).

The examples described above are by no means limiting and are provided solely for illustration and explanation.

Installing unused weapons in an upright position, for example, in a conventional gun pyramid, is not always possible or is easily practicable.

On Fig shows the support element (26) attached to the butt (7). The supporting element (26) is made in the form of a long pin, which is attached at one end to the butt (7) and can rotate in the transverse direction outward from the bed (1) and maintain it in an almost vertical horizontal position when installed on a solid surface. In FIG. 22 (a), the support member (26) is shown in the assembled position, and FIGS. 22 (b) and (c), respectively, are a side view and a plan view of the unfolded support member (26).

Although a single support member (26) is shown attached to the buttstock (7), it is understood that the invention is not limited to this. If desired, several support elements (26) can be provided that are attached at any convenient place on the lower second forend (8) and / or butt (7).

The attachment of the lower second forend (8) to the first pistol grip (5) or the second pistol grip (10) or the butt (7) or to all does not have to be rigid or fixed. In alternative embodiments, releasable, sliding, articulated and / or removable fasteners of the lower second forearm can be used (8).

23 illustrates one embodiment in which a second pistol grip (10) is attached to the first forearm (6) using an axis (27). The lower end of the second pistol grip (10) has a sliding fastening to the lower second forend (8) using a transverse finger or threaded bolts (28) passing through an elongated longitudinal (or arcuate) slot (29) in the side walls of the lower second forearm (8) .

Bolts (28), screwed into the base of the second pistol grip (10), allow the second pistol grip to be reliably and with the possibility of release in any particular place within the slot (29), thereby allowing the angle of inclination of the second pistol grip (10) to be adjusted. On Fig the second pistol grip is shown in the most extreme rear position in the slot (29), which gives the second pistol grip (10) backward inclination.

For comparison, in Fig.24, the second pistol grip (10) is shown fixed in the extreme front position of the slot (29), and the second pistol grip (10) has a forward inclination. The change in the angular position of the lower second forend (8) at the attachment point to the first pistol grip (5), caused by the sliding of the second pistol grip (10) along the slot (29), is allowed by the axis (30). If, as already noted above, the slot (29) has an arched shape that describes an arc relative to the axis (27), then the fastening of the lower second fore-end (8) to the first pistol grip (5) is not required to be rotary.

The slot (29) does not have to be at the front end of the lower second forend (8) (as shown in FIGS. 23 and 24); it can be performed in the place of attachment to the first pistol grip (5), as shown in Fig.25. In this embodiment, the fastening of the second pistol grip (10) to the lower second forend (8) is rotatable, but without slip correction.

In other embodiments, the simple sliding mount configuration shown in FIGS. 23-25 can be replaced with a telescopic configuration, as shown in FIG. Instead of the sliding fastening of the second pistol grip (10) in the slot in the lower second forend (8), the second pistol grip (10) is hinged to the part (8b) of the lower second forend (8). This part (8b) is attached telescopically to the rest of the lower second forend (8).

Although in FIGS. 23-26, the second pistol grip (10) with an adjustable angle of inclination is shown as part of a box (1) of a special design, the known box, for example, shown in figure 2, can also be redone so that it has the same features.

On Fig and 28 shows another embodiment of the present invention in relation to rifles with a pump-action shutter mechanism. In this embodiment, the upper first fore-end (6) is a pump-action shutter mechanism that is slidably mounted to a guide tube / magazine (31) located directly below the barrel (3) and shown (in FIG. 27) in its extreme forward position travel in the guide tube (31). The lower second handguard (8) is attached to the butt (7) and the first pistol grip (8) and has a sliding point to the lower end of the second pistol grip (10). In this embodiment, the sliding attachment of the lower fore-end (8) is made in the form of a guide (32) with an internal slot extending in the longitudinal direction, configured to keep the pistol grip (10) not falling out of the guide (32). The pistol grip (10) of the pump shutter mechanism performs a reciprocating linear motion parallel to the barrel. In order to remove a new cartridge (not shown), the shutter (6) is pulled back towards the butt (7) (as shown in Fig. 28), and then returned to its original position, shown in Fig. 27, in order to drive new cartridge in the box.

Adding a second lower fore-end (8) significantly improves the structural integrity of the pump-action shutter mechanism. In the case of conventional weapons with a pump-action shutter mechanism, the second pistol arms (10) that are free-standing without support are rarely used due to the potential malfunction of the pump mechanism due to transverse or torsional forces applied to the pistol grip (10). The present invention eliminates these disadvantages.

As a precaution, the lower fore-end (8) has an opening (33) through the guide (32), into which you can insert the handle of a padlock (not shown) to prevent unauthorized use of weapons.

On Fig shows a configuration comparable to that described with reference to Fig.27 and 28, in relation to the adaptation of known weapons with a pump-action shutter mechanism. All necessary changes are limited to replacing the conventional fore-end serving as a shutter, pistol-grip (or even attaching a second pistol grip to an existing shutter (6)) and adding a second lower fore-end (8) with attachment points on the second pistol grip (10), the first pistol handle (using the connecting rod (34)) to the butt (7).

On Fig also shows the mount (35) to the forearm of the gun belt, which is attached to the slider of the pump. And in this case, the increased structural rigidity of the weapon when adding the lower fore-end (8) allows you to position this mount without adversely affecting the action of the weapon. Fig. 30 is a section through the barrel (3) and the pump slider along line XX in Fig. 29 and illustrates the fastening (35) to the forearm of the gun belt and the corresponding swivel (36).

Further adaptation of the embodiment described with reference to FIGS. 27-30 is shown in FIG. Although in this embodiment, the second pistol grip (10) is shown attached to the shutter (6a) of the grenade launcher (37), the main difference lies in the reload sequence. Contrary to the action of the pump-action mechanism of the above embodiments, during the “push” stroke outward from the arrow, the grenade launcher pushes out the expended grenade cartridge and performs a reload during the reverse stroke in the direction of the arrow. And in this case, the pumping action is a reciprocating movement, and the lower end of the second pistol grip (10) is held in the second lower forearm.

On the contrary, on Fig shows an embodiment with a different cyclic action, in which the attachment of the lower fore-end (8) to the second pistol grip is a hinge (38) in a fixed place, and not a sliding mount. The charge / eject action of the pump mechanism is still the usual “eject” action described with reference to FIGS. 27-29. However, the linear movement of the second pistol grip (10) is replaced by movement along an arcuate path with rotation about the axis (38). Changing the angle of the lower fore-end (8) during the movement of the pistol grip (10) along the arc is allowed due to the hinged fastening (30) of the second fore-end (8) to the first pistol grip (5). Alternatively, a vertical slot can be made in the lower forend (8) at the attachment point to the second pistol grip (10). This will allow the fastening point (38) to move in the vertical direction during the pumping action and at the same time provide a rigid fastening of the lower fore-end (8) to the first pistol grip (5) and / or butt (7).

It is understood that a weapon with a pump-action shutter mechanism is only one of numerous examples of the application of the present invention. On Fig shows the use of the second lower forearm (8) as a support for shooting / aiming. The lower second fore-end (8) is disconnected from the second pistol grip (10) and rotated about the axis (30), and its free end is fastened to the arrow belt (39) or to the sheath or holder of a special design (not shown) that carries the arrow. This embodiment is suitable for standing shooting positions both in cases where long-term observation of the target is required (for example, at the border), and when hunters shoot from cover from trees, etc.

If it is possible or required a position for firing while sitting or crouching, the free removable end of the second forend (6) can be placed directly on the ground, as shown in Fig. 34. In Fig. 35, in more detail, one configuration of the attachment point between the second pistol grip (10) and the first forend (6) and the second forend (8), as shown in Fig. 34. In this embodiment, the second pistol grip (10) is attached using an axis (38) mounted in the second lower forearm through one of the three holes (41, 42, 43). These several holes allow you to change the slope of the pistol grip (10). The upper end of the second pistol grip (10) is pivotally attached to the first forearm (6) on an axis (27) attached to the palm rest (44). In an alternative embodiment (not shown), the inclination of the second pistol grip (10) can be determined by an adjusting screw or an emphasis in the upper part of the second pistol grip (10), and the lower end is fixed to the second forearm (8) using a slot of a certain shape. In the embodiment shown in FIG. 35, the second pistol grip (10) can also be adjusted to slide by loosening and tightening the bolts (43) passing through the palm rest (44). The thickening for the palm can be moved a predetermined linear distance under the first forend (6) and thereby set the angular position / inclination of the second pistol grip (10).

Another example of the universality of the lower second forend (8) is shown in Fig.36. In this case, the second fore-end (8), disconnected from the first pistol grip (5), together with the lower part of the second pistol grip (10) give a "nutcracker" configuration. In addition, by adding a pair of protruding cheeks (45) (as a continuation of the two levers of the nutcrackers), the configuration of the levers of the "nutcrackers" can be converted into a torch / crimping tool for wire, etc.

As another example, to illustrate the potential variety of lodge configurations possible in the practice of the present invention, other lodges (1) are shown in FIGS. 37-39. On Fig shows the bed, in which the attachment points of the second lower forearm (8) are on the butt (7), the first pistol grip (5) and the second pistol grip (10), and the second forearm is tilted down from the first pistol grip (5) in the direction of the butt (7). In addition, the bed has a backward facing third pistol grip (46) located between the butt (7) and the first pistol grip (5). The third pistol grip that is turned back is another place that the shooter’s free hand can hold in the hug position.

On Fig and 39 shows further examples of the installation of the lower second forearm on a known weapon. Fig. 38 illustrates the adaptation of a typical slide-lock rifle by adding a second articulated pistol grip (10) and an adjustable palm thickening (44) at one end of the lower fore-end (8) with the other end attached to the butt (7). The connecting rod or brace (34) creates an intermediate support for the lower fore-end (8) in the area of the first pistol grip. The rifle in FIG. 38 is further enhanced by the addition of a removable bipod, which is stored in the lower fore-end (8), and a support stand (26).

On Fig shows that the present invention can be applied even to a rifle with a lever shutter mechanism. This mechanism requires a free path for its movement, and therefore mounting on the first pistol grip is impossible. But the connecting rod or brace (34) can be attached to the first forend (6) from the near midpoint of the lower forearm (8) with further attachment points on the butt and (using the new second pistol grip (10)) closer to the front of the first forearm (6 )

Thus, the specialist understands that the proposed box with the second lower fore-end can be easily installed on a variety of existing small arms, as well as included in the design of the box at the development stage.

It is clear that the present invention is not limited to the described mounting methods, and that a wide variety of known alternative mounting methods may be equally suitable.

The features of the present invention are described by way of example only, and it is clear that other embodiments are possible within the scope of the invention defined by its claims.
