Description

The invention relates to the field of hand firearms, in particular to a quick-release bipod attached to it.

The bipod of the present invention is designed to be mounted on various types of small arms, having a mate in the form of a rail mounting system, for example, Picatinny or Weaver (PicatinnyRail/Weaverbase).

Known bipod, described in the patent "Method of quick attachment bipod assembly with adjustable and lockable control of rotation and tilt" (patent US2011126444 (A1), which consists of a mounting frame carrying the first and second retractable legs, and the bipod mounting frame is adapted for attachment to Said bipod mounting frame includes a tilt/rotate controller comprising first and second opposed clamping jaws. Said first and second retractable legs are movably pivotally connected to the mounting frame via a ball connector. Said tilt/rotate control includes a threaded shaft carrying the first a control handle, said threaded shaft is configured to forcibly loosen or tighten the first and second opposite clamping jaws and clamp on said ball connector. release of the clamp on the specified mounting post and controlled by the second control knob.

The disadvantages of analog are:

1. A large number of moving parts, which will complicate the use of a bipod in the field;

2. Impossible to mount on rifles with Picatinny/Weaver rails installed;

3. There is no discrete fixation of bipod supports.

The closest analogue ( prototype ) is a small arms bipod (patent RU 2345308 C2), which contains a base made in the form of a cylinder with a tide in the upper part and with pairs of blind holes for supports, supports with retractable racks located in them, devices for regulating the height of the racks and a spring device for fixing the supports in various positions relative to the base. The spring device is equipped with two deep glass-shaped thrust bearings suspended on trunnions and a guide core. The device for adjusting the height of the racks is made in the form of tension springs located inside the retractable racks, equipped with a latch and connecting the retractable racks with supports, and longitudinal grooves made in the supports with lateral inclined sockets for interacting with the mentioned clamps.

The disadvantages of the prototype are:

1. The inability to install a bipod on a modern weapon equipped with Picatinny / Weaver rails, in addition, the well-known bipod is made for one type of firearms - SV-98, it is not intended to constructively use this type of bipod on any other rifles;

3. The impossibility of a discrete change in the angle of inclination of the bipod supports;

4. There is no possibility of fixing a limited rotation relative to the longitudinal axis of the weapon, so the bipod is not fixed at the desired angle;

5. There is no possibility of mounting a bipod on a rifle in the upper and side positions.

To date, a large number of rifles are equipped with side, lower and upper Picatinny or Weaver rails, while the design of most bipods limits the shooter's ability to install the bipod in the upper and rarely in the lateral position relative to the rifle.

The technical problems of the claimed invention are:

- the use of a bipod on almost any type of firearms equipped with a Weaver or Picatinny rail;

- improving the accuracy of shooting from weapons,

- improving the usability of the bipod.

Technical problems are solved by the fact that a bipod for firearms, containing a base, supports with retractable posts with paws located in them, devices for adjusting the height of the posts and a spring device for fixing the supports in various positions relative to the base, holes are made in the lower part of the base for fixing telescopic supports in the working and stowed positions, differs from the prototype in that it contains a steel central with a protruding rod, made with the possibility of fixing on a rail attachment system, for example, a Picatinny rail or a Weaver, while the central rod is installed in a through hole made in the base of the bipod, while the central is provided with a screw that limits the rotation of the base on the central relative to the longitudinal axis of the weapon, and the base contains a spring-loaded screw that fixes the angle of inclination of the central at the base of the bipod; the side ends of the base contain holes with the possibility of discrete displacement and fixation of the supports at the angles relative to the shaft axis: 45 degrees, 90 degrees, 135 degrees and 180 degrees.

The essence of the invention is illustrated by sketches, which show:

Fig. 1 - expanded general view of the bipod of small arms with the center removed;

Fig. 2 - general view of the bipod assembly;

Fig. 3 - the upper position of the fixation of the bipod on the Picatinny rail / Weaver;

Fig. 4 - lower fixation position of the bipod on the Picatinny rail / Weaver.

The bipod of small arms (Fig. 1) contains a steel central 1, made with the possibility of fixing on the Picatinny rail or Weaver either in the upper (Fig. 3) or in the lower (Fig. 4) position using a clamp 11, made in the form of a rectangle with a reciprocal part that wraps around the Picatinny or Weaver rail during landing and securely fixes it by pressing the screws. The steel central 1 contains a protruding rod 10 with a shaft at the end, which is installed in the base of the bipod 2 through a through hole 9. The steel central 1 is equipped with a screw 7 that limits the rotation of the base of the bipod 2 on the central 1 relative to the longitudinal axis of the weapon in order to fix the angle of inclination weapons mounted on a bipod in a horizontal plane. The upper platform of the bipod 2 base contains a spring-loaded screw 8, which fixes the angle of inclination of the central 1 in the bipod base 2. Screw 8 attracts central 1 and does not allow it to rotate. Two spring-loaded supports 12 with a retractable stand 4 are fixed to the base 2 of the bipod. Each support 12, together with a spring (not shown in Fig.), is fixed to the base 2 with a screw 13. Each support has a spring-loaded button 3 for extending the stand 4 from the support 12. Height bipod in working position can be adjusted within 190-260 mm. Each rack 4 at its base contains a paw 5. Paw 5 has its own axis of partial rotation in order to compensate for the angle of inclination of the bipod support 12. Also, the paws 5 have an increased area, so that the area of conjugation of the paws 5 with the surface on which the bipod is installed is maximum. This increases the stability of the structure. The side (left and right) ends of the base of the bipod 2 contain holes 6 of discrete displacement of supports 12. Discrete displacement of supports 12 involves the installation of supports 12 in various variations of a fixed direction - at angles relative to the axis of the barrel: 45 degrees, 90 degrees, 135 degrees and 180 degrees . In each position, the support 12 of the bipod is rigidly fixed, and allows the shooter to fire from below, not only in the horizontal plane, but also from top to bottom and from bottom to top, and also allows you to transfer the bipod to the traveling or working position. In the stowed idle state, the bipod supports 12 are folded in the direction of the barrel of the weapon or in the direction of the receiver. Holes 6 are blind (like a groove) into which a spike (not shown in Fig.) is inserted, located on the inside of the bipod supports 12, which rigidly fixes the angle of inclination of the support 12 and has equal angles of inclination on each side of the ends of the bipod base 2. In this case, the supports 12 can be placed parallel to each other. In addition, the spike and holes 6 for fixing are made in the form of a cone, which eliminates the appearance of play during the operation of the product and provides a more accurate fit.

As the material of the central 1 and supports 12 with uprights 4 can be used, for example, duralumin.

Moving the bipod from the traveling position to the working position.

The base 2 of the bipod can be carried separately from the central 1, which is pre-installed and fixed on the weapon (on the Picatinny rail or Weaver).

In this case, the bipod is put on the base 2 through the hole 9 on the central 1 fixed on the bar. After the lock button in the form of a spring-loaded screw 8 snaps the neck of the shaft of the rod 10 of the central 1, the bipod is securely put on the rifle. Then, releasing the screws 13 and pulling the supports 12 from the base 2 (each support is spring-loaded), the supports 12 are installed with a spike (not shown in the figure) in the hole-groove 6 that corresponds to the choice of the shooter.

The principle of choosing a thorn-groove position: for example, if it is necessary to perform shooting from a limited space in height, use the direction of the supports not 90 degrees, but 45 degrees in the front or 135 degrees in the rear installation. 0 degrees and 180 degrees for ease of transportation. 90 degrees is the classic method of using bipods on weapons.

So it is necessary to do with each of the two supports 12, setting them parallel to each other. Then, racks 4 with paws 5 are pulled down from the supports 12 to the required height. The height is fixed with a spring-loaded button 3. After that, the bipod is placed with its paws on a horizontal surface. The rifle is then considered mounted on a bipod.

Moving the bipod from the working position to the traveling position.

By pressing the locking button 3, the racks 4 are pushed (removed) into the supports 12 to the minimum level. Pulling the supports 12, releasing the screws 13, place the supports 12 in the extreme right (or left) position by placing the spike in the corresponding hole-groove 6. The extreme left and right holes-grooves 6 are transport positions. By depressing the button 8 for fixing the central 1 in the base 2 of the bipod, the base 2 of the bipod is removed from the central 1. After that, the bipod is brought into the transport position.

Thus, the technical results of the invention are:

1. The ability to quickly and easily install a bipod on a rifle in any position, even sideways: when mounted on the top, the area of \u200b\u200bsupport for the rifle on the surface increases, which gives advantages when shooting, since a large area of \u200b\u200bsupport increases the stability of the shooter as a whole, which means it increases accuracy shooting from weapons;

2. The ability to discretely change the angle of inclination of the bipod supports, which increases the ease of use of the weapon, which in general also increases the accuracy of shooting.
