Abstract

The present utility model pertains to a disposable grenade launcher with a dual sight module and would be applied in the weapons industry and in particular in the manufacture of portable grenade launchers. The disposable grenade launcher with a dual sight module created according to the present utility model consists of a container (4) with a front lid (2) and a rear lid (3), wherein a hammer-and-trigger assembly (1) is mounted near the rear lid (3). A mechanical sighting module including a movable arm (9) which carries a back sight (8) and a muzzle sight (7) is mounted between said hammer-and-trigger assembly (1) and front lid (2). Also mounted on a carrying section (14) established in the rear end of said arm (9) is an optical collimator sight (13). The dual sight module also includes a ballistic plate (5) secured laterally and directly to the container (4). Said movable arm (9) can be rotated around an axle (6) and can be locked in holes (10) in said ballistic plate (5) by means of a retainer (11) under the force of a spring (12) which functions in a direction parallel to said rotational axle (6).

Description

Field of technique

The present utility model relates to a single-use grenade launcher with a dual sighting module that will find application in the arms industry and in particular in the production of hand grenade launchers.

Prior art

The hand-held grenade launcher is an individually portable, single-action firearm designed to engage tanks, self-propelled artillery, and other armored vehicles, as well as to engage manpower in bunkers, light field shelters, and urban-type brick structures.

The main mechanisms that each grenade launcher includes are an aiming mechanism, a grenade, which consists of a cumulative warhead with a piezo-electric detonator, a jet engine and a node for attaching the grenade. From practice, disposable grenade launchers are known, including a front sight and a sight, fixed on a movable arm, which is locked in a vertical ballistic plate, clamped to a horizontal base on top of the container. Locking is provided by a spring force acting perpendicular to the arm's axis of rotation.

From Registered Utility Model No. 5660 U, a single-use grenade launcher with a mechanical sighting module is known, which includes a container with a front cover and a rear cover. Near the rear cover, a shock-trigger mechanism is installed, and between the shock-trigger mechanism and the front cover there is a movable arm with a sight fixed on it at its front end and a sight at its rear end. According to the utility model, the movable arm with the sight and front sight located on it is part of a mechanical sighting module that also includes a ballistic plate clamped laterally and directly to the container. The movable arm is able to rotate around an axis and can be locked in holes made on the ballistic plate by means of a retainer, under the influence of a spring operating in a direction parallel to the axis of rotation.

Technical nature of the utility model

The task of the utility model is to create a single-use grenade launcher with a dual sighting module with a simplified design, containing an optical collimator sight that provides fast, reliable and accurate aiming.

The task was solved by creating a single-use grenade launcher with a dual sighting module, including a container with a front cover and a rear cover. Near the rear cover, a shock-trigger mechanism is installed, and between the shock-trigger mechanism and the front cover there is a movable arm with a sight fixed on it at its front end and a sight at its rear end. The front sight and sight are part of a mechanical sight module that also includes a ballistic plate clamped laterally and directly to the container. The movable arm is capable of rotating around an axis and capable of being locked in holes made on the ballistic plate by means of a retainer, under the influence of a spring operating in a direction parallel to the axis of rotation.

According to the utility model, the dual sight module also includes an optical collimator sight mounted on a support portion of the movable arm formed at its rear end.

An advantage of the created single-use grenade launcher is that the created design is technologically simplified, and the presence of an optical collimator sight increases the accuracy and speed of aiming. In addition, due to the fact that the direction of the locking force of the spring has been changed to horizontal, the action with the grenade launcher is easier and more precise.

Explanation of the attached figures

The present utility model is illustrated in the attached figures, where:

Figure 1 is an axonometric view of a single-use grenade launcher with a dual sighting module, according to the utility model;

Figure 2 is a view of a mechanical sight module according to the utility model;

Figure 3 is a section along B-B of Figure 2 and

Figure 4 is a view of the movable arm of a single-use grenade launcher with a dual sighting mechanism, according to the utility model.

Examples of implementation of the utility model

The created single-use grenade launcher with a mechanical sighting module, shown in figure 1, includes a container 4 with a front cover 2 and a rear cover 3, and a shock trigger mechanism 1 is installed near the rear cover 3. Between the shock trigger mechanism 1 and the front cover 2 a mechanical sighting unit shown in Figures 2 and 3 is located, comprising a movable arm 9 with a front sight 7 mounted on it at its front end and a sight 8 at its rear end. The front sight 7 and the sight 8 are part of a mechanical sight module, including a ballistic plate 5, clamped laterally and directly to the container 4. The movable arm 9 is capable of rotation around the axis 6 and can be locked in holes 10 made on the ballistic plate 5 through a retainer 11, under the influence of a spring 12, operating in a direction parallel to the axis 6 of rotation. The double sight module also includes an optical collimator sight mounted on a supporting part 14 of the movable arm 9 formed at its rear end.

The single-use grenade launcher with dual sight module works as follows.

The catch 11 is pulled out, which rests the movable arm 9, allowing it to be rotated to the desired firing distance, then when the catch 11 is released, it enters the corresponding hole 10 and moves to aiming using the front sight 7 and sight 8 or with the optical collimator sight 13. The latch 11 acts under the influence of the spring 12, which works in a direction parallel to the axis 6 of rotation. In this way, easier and faster positioning of the mobile arm 9 is ensured.
