BG4411U1 - Disposable grenade launcher with a mechanical sighting module - Google Patents

Abstract

The present utility model relates to a disposable grenade launcher with a mechanical sighting module that would be applied in the armaments industry and in particular in the production of portable grenade launchers. The disposable grenade launcher with a mechanical sighting module created according to this utility model includes a container (4) with a front lid (2) and a rear lid (3), wherein a firing assembly (1) is accommodated near the rear lid (3). A mechanical sighting module consisting of a movable arm (9) which carries a back-sight (8) and muzzle sight (7) is accommodated between the firing assembly (1) and the front lid (2). The mechanical sighting module also include a ballistic plate (5) secured directly to one of the sides of the container (4). The movable arm (9) can be rotated around an axis (6) and fixed in holes (10) machined in the ballistic plate (5) by a fixator (11) under the force of a spring (12) the action of which is in a direction parallel to that of the rotational axis (6).

Description

The present utility model relates to a single-use grenade launcher with a mechanical aiming module, which 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 individual portable single-action firearm and is designed to engage tanks, self-propelled artillery and other armored vehicles, as well as to engage manpower located 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.

Technical nature of the utility model

The task of the utility model is to create a single-use grenade launcher with a mechanical aiming module with a simplified design that provides fast and reliable aiming.

The task was solved by creating a single-use grenade launcher with a mechanical aiming module, which includes a container with a front cover and a rear cover. Near the rear cover there is a shock trigger mechanism, and between the shock trigger mechanism and the front cover there is a movable arm with a sight and front sight installed on it. According to the utility model, the movable arm with the sight and front sight located on it is 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.

An advantage of the created single-use grenade launcher is that the created structure is technologically simplified. 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 disposable grenade launcher with a mechanical sighting module, according to the utility model;

Figure 2 is a view of a mechanical sight module according to the utility model; and Figure 3 is a section along B-B of FIG. 2.

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 near the rear cover 3 a shock trigger mechanism 1 is installed. Between the shock trigger mechanism 1 and the front cover 2 a mechanical sighting module shown in Figures 2 and 3 is located, including a movable arm 9 with a sight 8 and front sight 7 fixed thereon. The mechanical sighting module also includes a ballistic plate 5 clamped laterally and directly to the container 4. The movable arm 9 is capable for rotation around the axis 6 and with the possibility of locking in holes 10 made on the ballistic plate 5 by means of a retainer 11, under the influence of a spring 12 operating in a direction parallel to the axis 6 of rotation.

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

The latch 11 is pulled out, which rests the movable arm 9, allowing it to rotate to the desired firing distance, then when the latch 11 is released, it enters the corresponding hole 10 and moves to aiming using the front sight 7 and sight 8 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 arm positioning is ensured.

Claims (1)
