Description

The utility model relates to the design of devices designed to protect a serviceman from bullets and shrapnel in combat conditions.

A connecting protective shield is known, and the shields inserted into each other form a single protective wall, which more evenly distributes the pressure of the advancing crowd and the load on each individual employee of law enforcement agencies. A single system of connected shields eliminates the danger of breaking the chain of shields and employees, eliminates the possibility of thrown objects or strikes between the shields. A single wall of connected shields can more effectively restrain the onset of the crowd when streets are blocked, various passages in buildings and between buildings (utility model patent RF 199058, publ. 11.08.2020).

As a result of patent research, a lightweight armor protection system has been identified, consisting of articulated armored shields that can be folded and form a parapet (WO 2009131727).

As a result of a comparative analysis of the essential features, the applicant adopted as a prototype a protective device made of separate flat protective segments interconnected by a hinged joint by means of an axis, characterized in that the connecting axis is located vertically, the protective segments are located at an acute angle to each other and are fastened with a connecting rod, the end parts of which are made with locks, one of which is made removable in the form of a nut mounted on the threaded shank of the rod, the end parts of the rod are placed in the through holes of the protective segments, while one protective segment has a viewing window covered with bulletproof armor glass, and in the other - a hole for placing small arms, in each segment there is a hole with an internal thread, in which an L-shaped stopper is installed, one end of which is made with an external thread, and the other is pointed (utility model patent of the Russian Federation No. 154962, publ. 20.09 .2015).

The disadvantage of this device is that when a bullet or shrapnel hits the armor protection panel, the entire panel as a whole fails, so it is necessary to replace the completely deformed panel during repairs. In addition, the known device has limited functionality.

The technical task of the claimed utility model is to expand the functionality while improving the reliability of operation.

The technical result is to ensure the versatility of the proposed device while improving the reliability of its operation.

The technical result, aimed at improving the reliability of operation, is expressed in maintainability in the field by providing the possibility of replacing the deformed section of the armor protection panel with an undamaged panel and increasing the service life of the shield.

The technical result, aimed at providing versatility, is that the inventive design can be used at the same time as a shield itself, and it also provides the possibility of transforming it into a parapet, the possibility of using it as an auxiliary means for transporting the wounded and / or ammunition, the possibility of using it as a temporary , and a relatively permanent, conditionally capital type (dugout / dugout) shelter, for example, from flying vehicles, in particular reconnaissance drones, the ability to reinforce firing points in buildings and structures.

The stated technical problem is solved by the fact that a transformable shield against impact-fragmentation is declared, made of separate protective segments interconnected by a swivel by means of an axis, characterized in that the swivel is made along the edges of the shield, the articulating parts of the swivel at the edges of adjacent protective segments represent are hollow cylinders, the protective segments are curved and arranged one after the other, with each axle having a stop in the lower part, and a latch in the upper part.

Comparison of the proposed technical solution with the prototype shows that it has the following features:

swivel is made along the edges of the shield;

the articulating parts of the swivel at the edges of the protective segments are hollow cylinders;

protective segments are curved;

protective segments are located one after another;

each axis has a stop in the lower part, and a lock in the upper part.

Therefore, we can assume that the proposed technical solution meets the criterion of "novelty".

The utility model can be manufactured on well-known equipment, so it meets the criterion of "industrial applicability".

Figure 1 schematically shows the inventive transformable shield,

figure 2, 3 schematically shows the protective segment,

figure 4 schematically shows the use of a transformable shield as a parapet.

The device contains curved protective segments 1, assembled into a shield (figure 1), in which they are located one after the other by means of a swivel spaced along the edges of the shield. The articulated parts of the swivel at the edges of the protective segments are made in the form of hollow cylinders 2, 3 (figure 3), preferably at half the height of the segment 1. stops 6, 7 in the upper part, and latches 8, 9 in the upper part. Any elements known for these purposes can be used as stops 6 and 7 and latches 8 and 9. The protective segment 1 can be made of a single layer of armor plate, for example, alloy steel, or aluminum alloys, or titanium alloys, metal ceramics or can be made of two layers, for example, an armor plate and a polymer layer, such as UHMWPE, aramid fibers and other suitable materials .

The transformable shield can be assembled right on the battlefield to protect the soldier. To do this, the protective segments 1 are sequentially threaded on the axles 4 and 5 by means of hollow cylinders 2 and 3 on both sides. In this case, the axles 4 and 5 in the initial position are located with stops 6 and 7 down. In order to prevent the protective segments 1 from flying off the axles 4.5 during the movement of the shield, clamps 8.9 are installed in the upper part of the axles 4.5. The assembled shield is shown in figure 1, where the protective segments 1 are curved in one direction. In case of failure of any protective segment 1, when hit by a bullet or shrapnel, it is replaced, while maintaining entire protective segments in the shield. To replace the deformed protective segment 1, it is necessary to remove the clamps 8 and 9, remove the deformed protective segment from the axes 4 and 5, replace it with a whole one by stringing it on the axis 4, and reinstall the clamps 8 and 9 on the axes 4 and 5.

Transformable shield can be assembled in the form of a parapet (figure 4). To do this, the protective segments 1 are also successively threaded by means of hollow cylinders 2 and 3 on the axis 4 and 5 as shown in Fig.4. In the offensive, when moving lying down, a soldier can move in front of him, and in defense, crushed stone, broken stone, soil, etc. can be loaded into the cavity of the parapet, which will increase the effectiveness of protection.

At present, a prototype of a transformable shield has been made. Tests have shown that the inventive shield, assembled in the form of a parapet, protects against armor-piercing bullets of caliber 7.62 × 54 at a distance of up to 200 m in 50% of hits, at a distance of more than 500 m it protects completely. Smaller bullet calibers do not penetrate the parapet assembled from the inventive convertible shield. If a partition made of ballistic materials is installed inside such a parapet, armor-piercing bullets of normal caliber (up to 12.7 mm inclusive) do not penetrate the parapet even at distances up to 200 meters. Large calibers (from 12.7 mm and above) require either the additional installation of additional partitions from ballistic partitions in the claimed shield, or the installation of several claimed shields in front of each other, or the creation of partitions filled with soil and other materials, or without them, but with significant increases personnel destruction distance (over 1000 m and more).

When the inventive transformable shield is installed to large trees in the forest, the fighters have the opportunity to survive and continue to fight under fire from heavy machine guns and rifles.

When installing the inventive transformable shield inside broken capital structures (apartment or other buildings, industrial production shops, etc.), it becomes possible to create reinforced conditionally long-term firing points like a pillbox and / or dugout in those places where, without the use of armor, firing points or impossible, or limited possible (openings of windows, broken openings of walls, ceilings, etc.).

When installing the inventive convertible shield inside a truck, it is possible to create a semi-armored dumbbell, and when booking a cab - a full-fledged dumbbell, while the design of the proposed shield provides the possibility of both open and, more importantly, hidden booking.

The inventive shield can also be used to transport ammunition or the wounded, because. the curved shape of the shield provides a small frictional force in contact with any type of surface, and the shape allows you to place the wounded or items of ammunition or other equipment in the box formed by the bending of the segments. This greatly facilitates the above tasks and allows you to save the physical strength of the fighters.

Also, the inventive convertible shield can be transported to the place of its assembly by any means of transport, tk. guards can be stacked on top of each other without taking up much space and allow for relatively easy unloading/carrying by almost any fighter.

The inventive design of the shield due to the provided swivel allows for quick installation in front of or directly at the fire contact on the line of clashes. At the same time, in case of loss of the axis or stop or latch, their function can be performed by improvised means - branches, stones, etc.

The inventive shield, due to the shape of the protective segments and their connection by the inventive swivel joint, is able to provide protection against bullets of caliber 5.45, 5.56 7.62 at distances less than 700 meters and, more importantly, from fragments of mines 80-82 mm, less often from 120-122 mm mines and other high-explosive fragmentation artillery shells, and from aviation NURSs (like high-explosive fragmentation missiles S5 or S-8OFP1).

Thus, the claimed utility model allows for the multifunctionality of the shield, while increasing the reliability of its operation, including by repairing by replacing the deformed segment of the shield in the field in the event of protracted battles, and when the combat situation changes, it provides the ability to use it as a parapet or as temporary and relatively permanent shelter, of a conditionally capital type, protection against existing systems for destroying enemy rifle and machine-gun fire or mortar fire, for real protection of personnel from fire damage.
