Description

The invention relates to the military field, in particular to the attachment of various attachments to the barrel of a hand-held grenade launcher.

Various types of barrel attachments are known from the prior art, for example, a muzzle brake, a flame arrester, a silencer, a rifled attachment, a projectile programmer (control of the trajectory and/or the moment of detonation).

To attach known attachments to the barrel, various methods are currently used, for example, the threaded method of attaching the attachment (see, for example:

- thread on the Saiga barrel (https://rotor43.ru);

- muzzle attachment KK Saiga (https://www.huntworld.ru/);

- muzzle attachments for barrel threads (https://tempgun.ru/catalog/tyuning_oruzhiya/dulnye_nasadki_i_udliniteli_stvola/?ysclid=m2umt5ays y849699856);

- a nozzle with a groove for a smoothbore gun (https://www.pro-shooter.ru/product/dulnaya-nasadka-sayga-12-sdu-150-paradoks).

The threaded mounting method requires a change in the design of the existing attachmentless models, and prevents the use of standard hand-held grenade launcher aiming devices and standard attachments for attachmentless models.

The flange-bolt mount of the nozzle of the Swiss Oerlikon Contraves AHEAD projectile programming system is known from the state of the art (see https://btvt.narod.ru/4/rarn_airburst.htm).

The disadvantage of the known method of fastening is the impossibility of quickly removing and/or replacing the nozzle.

The objective of the claimed invention is to create a fairly simple, easy-to-use and lightweight (weighing less than 330 g) attachment to the barrel of a hand-held grenade launcher (RG).

The technical results of the claimed invention are:

- the ability to ensure simple and quick installation (within 15 seconds) and dismantling (within 5 seconds) of various attachments, including a programming device, without additional tools and changes to the design of a standard attachmentless hand-held grenade launcher;

- ensuring reliable fixation of the brackets between themselves and various attachments on the hand-held grenade launcher;

- elimination of obstacles to aiming through sighting devices, such as a bar and/or optical sight, when installing the mount;

- improving the performance characteristics of a hand-held grenade launcher due to the simplicity and ease of installation of various attachments.

The technical results are achieved by the fact that the attachment to the barrel of a hand-held grenade launcher contains:

- primary and secondary clamps - pincers, connected to each other by a hinge, with the ability to grasp the barrel of a hand-held grenade launcher from two outer sides;

- a fixing ring designed to be placed on the brackets to fix them in a compressed position and to fix the attachment on the brackets.

In particular, preferred embodiments:

- to facilitate installation and removal of the fastener, the brackets can be connected to each other through two hinges, with an intermediate element;

- to ensure more reliable fixation of the brackets between themselves and various attachments on the hand-held grenade launcher, the brackets are made with an internal radius close to or equal to the external radius of the barrel in the area of attachment (due to the increase in the area of contact of the attachment to the barrel);

- one or both brackets may have a cutout or cutouts for gripping protrusions on the barrel, in particular, for geometrically locking the fastening on the barrel in the axial direction;

- to enable the screwing of the retaining ring onto the primary bracket with fixation of the position of the secondary bracket and the attachment, the primary bracket and retaining ring may have a mutually coordinated thread;

- the mount is designed with the possibility of transmitting signals between the grenade programming attachment and the control unit of the said attachment installed on the mount.

The features and essence of the claimed invention are explained in the following detailed description, illustrated by drawings, which show the following.

Figures 1 and 2 show the design of the claimed attachment to the barrel of a hand-held grenade launcher, where the following is designated under identical reference positions:

1 - barrel;

2 - primary bracket;

3 - secondary bracket;

4 - nozzles;

5 - fixing ring;

6 - internal thread of the retaining ring;

7 - external thread of the primary clamp;

8 - sight mount;

9 - external element of the barrel;

10 - slot in the secondary bracket;

11 - recess of the secondary bracket;

12 - primary bracket flange;

13 - intermediate element;

14 - axis of rotation of the secondary bracket and intermediate element;

15 - axis of rotation of the primary bracket and intermediate element.

The attachment of the nozzle to the barrel of a hand-held grenade launcher (see Figs. 1 and 2) comprises a pair of clamps - pincers (2,3), connected to each other by a hinge, with the possibility of grasping the barrel 1 of the hand-held grenade launcher from the outside, and a fixing ring (5), made with the possibility of being put on the clamps (2,3) for fixing them in a compressed position and fixing the nozzle (4) on the clamps (2,3).

The primary bracket (2) is made with an internal radius equal to or close to the external radius of the barrel (1) of the hand-held grenade launcher and contains a cylindrical part in the area of the barrel cut (1), which has an external thread (7), and a cutout for placing a mount (8) for the sight.

The secondary bracket (3) is pivotally connected to the primary bracket (2) via an intermediate element (13) and comprises a recess (11) matched in size to the flange (12) of the primary bracket (2), which allows the flange (12) of the primary bracket (2) to fit tightly into the recess (11) of the secondary bracket (3). Also, the secondary bracket (3) has slots (10) for the outer element (9) of the barrel (1).

A fixing ring (5) with the possibility of limited axial displacement is placed on the nozzle (4), which has an internal thread (6) matched with the external thread (7) of the primary bracket (2).

The principle of installing the attachment (4) on the barrel (1) of a hand-held grenade launcher is as follows.

The primary bracket (2) is placed on the barrel (1) of the hand grenade launcher, and the mount (8) for the sight enters the slots of the primary bracket (2), thereby fixing the primary bracket (2) in the axial direction.

The secondary bracket (3) rotates on hinges and is placed on the barrel (1) on the opposite side relative to the primary bracket (2), wherein the flange (12) of the primary bracket (2) enters the recess (11) of the secondary bracket (3), thereby fixing the secondary bracket (3) in the axial direction.

The locking ring (5) is placed on the primary bracket (2) and screwed onto the thread, whereby the locking ring (5) clamps the secondary bracket (3) from the outside, fixing both brackets (2,3) in the radial direction on the barrel (1) and simultaneously presses the nozzle (4) to the primary bracket (2).

The analysis of the state of the art made it possible to establish that there are no analogues with a set of essential features identical to the essential features of the claimed fastening, which indicates that the claimed invention meets the patentability condition of “novelty”.

The results of the search for known technical solutions in order to identify essential features that coincide with the essential features of the claimed device that are distinctive from analogues have shown that they do not follow explicitly from the state of the art, and the influence of the distinctive essential features on the specified technical results has not been established. Consequently, the claimed invention meets the patentability criterion of "inventive step".
