RU2533861C1 - Small arms bipod - Google Patents

Abstract

FIELD: weapons and ammunition.

SUBSTANCE: small arms bipod comprises a base with ledges, on which two folding supports are hingedly fixed by the axes. On each of the supports the tubular handle is mounted, pressed by a spring in the direction of the hinge joint. On each of the supports there is a helical groove, and on the handle - the screw having an end with the cylindrical part, which enters into the groove. The groove and the screw together form a screw pair.

EFFECT: enhanced ease of performing of operation of folding the bipod supports.

Description

The invention relates to firearms, in particular to the device of machine guns and sniper rifles.

Known bipod small arms (see patent RU No. 57883 U1, 10.27.2006), adopted as a prototype. The bipod contains the base and the folding hinge supports mounted on it. On the base there are conical recesses into which the ends of the supports enter and are held inside them by means of springs. When pulling the support from the base, the end of the support comes out of the conical recess, which allows the support to rotate on the axis for folding or unfolding.

The disadvantage of the design of the bipod is the inconvenience of the operation of folding (unfolding), especially if the manipulations are performed from uncomfortable positions for the shooter, for example lying down, stretching his arms forward.

The proposed invention solves the problem: creating the convenience of bringing the bipod in a combat or traveling position.

The technical result obtained by carrying out the invention consists in the fact that, for the convenience of performing the operation of unfolding the supports, the new design of the bipod allows replacing the pulling movements on the outstretched arms, in which the shoulder muscles participate, by an action by turning the wrist, in which the muscles of the hand and forearm are involved . The latter are performed easily, regardless of the position of the body occupied by the shooter.

The specified technical result is achieved in that in the bipod of small arms containing a base and folding hinge supports, it is new that on each of the supports there is installed a tubular spring-loaded handle with the ability to move along the support to lock or release the hinge, and the support is connected with the handle screw pair.

When the handle rotates, thanks to the screw pair, the handle moves along the support to the side of the hinge, revealing it, and thereby allowing the support to be folded. And, on the contrary, with the reverse action, when the bipod is unfolded, if the handle is not held by the hand, it is pushed over the hinge under the action of the spring, fixing the support relative to the base.

Thus, when unfolding the bipod, the support is unlocked by axial rotation of the handle using only one hand, which is ergonomically more convenient in comparison with the transverse pulling of the supports, where the shoulder muscles are also involved.

Technical solutions with features distinguishing the claimed solution from the prototype are not known and do not explicitly follow from the prior art. This suggests that the proposed solution is new and has an inventive step.

The essence of the technical solution is illustrated by drawings, which in a simplified form shows a structural diagram of the bipod of small arms. Separate structural elements of the bipod, not related to the subject of the invention, conventionally not shown.

Figure 1 - General view of the bipod (support laid out);

figure 2 is a section aa;

figure 3 - image of the support in the folded position.

The small arms bipod (Fig. 1) contains a base 1 with protrusions 2, on which two folding supports 4 are pivotally mounted using the axles 3. A tubular handle 5 is mounted on each of the supports 4, which is pressed by a spring 6 to the side of the hinge joint. On each of the supports there is a spiral groove 7, and on the handle there is a screw 8 having an end with a cylindrical part 9 by which it enters the groove 7. Together, the grooves and the screw form a screw pair.

In the folded position, the support 4 is held due to the fact that the handle 5 is pressed by the spring 6 to the side surface 10 of the protrusion 2.

To unfold the support 4, it is enough to pull it in the transverse direction (in a plane perpendicular to axis 3). At the same time, the handle 5, sliding along the surface 10, first compresses the spring 6. And when the support 4 takes a vertical position, the handle 5 slides along the support 4 upwards, covering the protrusion 2, and with it the axis 3 of the hinge joint. Support 4 will take a fixed position, the bipod is unfolded.

Thanks to the screw pair during axial rotation of the handle 5, it is shifted down along the support 4, revealing the axis 3. Thus, the support 4 is able to rotate to translate it into a folded position (figure 3).
