Description

The invention relates to means of protecting a person from the effects of an explosion, namely, to means of protecting a person from an explosion of a military grenade accidentally dropped by him when it is thrown for educational purposes.

In the Armed Forces of the Russian Federation, as well as in the armies of other countries, the training plans for combat training provide for a lesson called "throwing a combat grenade." (In the future, a man throwing a combat grenade will be called a soldier). Every year, in the Armed Forces of the Russian Federation, in military training classes when throwing a combat grenade for training purposes, soldiers accidentally drop grenades with an extracted safety pin that falls next to the soldier, followed by an explosion 4 seconds after the grenade leaves the soldier’s hand. Most often, such cases end in the death of a soldier, since he does not have time to pick up a grenade and at least throw it aside, and he can only move away from it by a few steps. There are times when an instructor or commander standing next to a soldier manages to take several steps, covers the grenade with his body and at the cost of his life saves the life of a soldier.

Here are the last two cases that have become widely known due to the fact that the officers who accomplished the feat were awarded the title “Hero of the Russian Federation”. 03/28/2013 Major S. Solnechnikov at the cost of his life he saved the soldiers subordinate to him when one of them accidentally dropped a combat grenade. 09/25/2014 Colonel Sultangabaev S.G. he covered his body with a grenade accidentally dropped by a soldier and saved his life. Colonel Sultangabaev S.G. He was seriously injured, but remained alive thanks to body armor. He is still under treatment.

Many cases of deaths and injuries of soldiers in combat training classes, and not only as a result of the explosion of randomly dropped combat grenades, for well-known reasons, are not widely publicized. Poor training of soldiers, their lack of discipline, poor organization and provision of training, exercises, training in combat training, and other shortcomings and mistakes in this area, undoubtedly, in many cases are the causes of the death of soldiers. However, the death of soldiers as a result of the explosion of a randomly dropped combat grenade is a special case. The fact is that, even if all the shortcomings listed above are eliminated, the deaths of soldiers as a result of the explosion of a randomly dropped combat grenade will continue. Here we are dealing with the fundamental law of nature: everything that a person can hold in his hands, he can accidentally drop. People drop dishes, keys, pens, tools, weapons, food, etc., and even their own children. A combat grenade in the hand of a soldier who first took it in his hands is a lot of stress and anxiety. And the latter are the prerequisites for committing errors and wrong actions (Kotik MA Psychology and Security. Ed. 2nd ed. And add. - Tallinn: Valgus, 1987. - 440 p.). To overcome this stress and anxiety, training and simulation grenades have recently appeared. At the exhibition "Integrated Security - 2015", which was held at VDNH in Moscow in May 2015, training and simulation grenades of the RAG type were presented, which simulate not only the sound of an exploding grenade, but also the flight of its fragments. These training and simulation grenades help reduce the stress and anxiety of a soldier who first picked up a combat grenade, and helps to raise morale and morale before throwing it. It helps to reduce, but does not eliminate stress and anxiety. This means that soldiers dropped, drop and will drop combat grenades during their training throw. Explosions of combat grenades at the feet of soldiers will continue, and no training, any training, imitations, psychological influences with the aim of raising morale and morale will reduce the probability of this event to zero. It is for this reason that it is necessary to focus on technical counteraction to the consequences of a grenade explosion. The invention is aimed at solving this problem.

To date, many countries have patented devices to protect people and property from explosion. Typical of them are, for example, inventions according to A.S. USSR No. 1251722, No. 2047923 (both class G12B 17/08). These devices and their analogues long before the alleged explosion are between the protected object and the place of the explosion. A soldier who accidentally drops a combat grenade in combat training classes has only 4 seconds to seek refuge. Even if you put, for example, a shield against the effects of the explosion according to the patent of the Russian Federation No. 2047923 (G12B 17/08), or another similar device, during training exercises in combat training with a military grenade throwing, the latter may be accidentally dropped between the shield and the soldier or behind his back. This is the same as throwing a grenade from a trench. For this reason, various devices or screens for protection against explosion cannot be considered analogues of the claimed invention. Analogues of the claimed invention, that is, devices that prevent the fall of a combat grenade between a soldier and a protective shield in case of accidental drop, were not found. Therefore, we assume that the claimed invention has no analogues.

The purpose of the invention is the protection of a soldier from the consequences of an explosion of a military grenade accidentally dropped by him when it is thrown for educational purposes.

This goal is achieved in that the device includes a protective container made in the form of a straight, circular, hollow, truncated cone, and a hoodie, the hem of which is worn on top of the truncated part of the cone around its entire perimeter.

In FIG. 1 shows a perspective view of a protective container made in the form of a straight, circular, hollow, truncated cone; in FIG. 2 - hoodie; in FIG. 3 - the position of a soldier at the time of throwing a combat grenade for educational purposes; in FIG. 4 - the position of the soldier at the time of the explosion of a correctly thrown combat grenade; in FIG. 5 - position of a soldier at the time of the explosion of a military grenade accidentally dropped by him; in FIG. 6 is a variant of a protective container made in the form of a collapsible, regular, truncated pyramid.

The protective container is made of steel or other material and contains a side surface 1, a hatch 2, a bottom 3 made integrally with the side surface 1, or welded to it, or attached in another way. Hoodie 4 is made of smooth material of medium rigidity, does not have pockets, buttons and other details for which the grenade can catch. The sleeves 5, 7 and the collar 6 are provided with cuffs to prevent the grenade from slipping between the sleeve, the collar and the body of the soldier. Cuffs on sleeves 5, 7 can be equipped with elastic bands. Hem 8 below is equipped with sinkers 9, attached around its perimeter. The size of hem 8 in its diameter and length corresponds to the diameter of the truncated cone and hatch 2 so that the hem can freely move up and down along surface 1. Hood 4 can be, as is customary in the Armed Forces for workwear, of three sizes - small, medium and big. The size of the protective container and the diameter of the exit hatch 2 correspond to the size of the hoodie.

Device operation

The soldier puts on a hoodie 4 corresponding to its size, fits into the protective container through the hatch 2 (or, on the contrary, first fits and then puts it on), puts hem 8 on a truncated cone (hatch) along its side surface 1, weights 9 pull hem 8 down, straightening it way from the folds of the entire hoodie 4 (Fig. 3). The soldier is ready to throw a combat grenade. The instructor gives the soldier a combat grenade with an unexploded safety check and leaves for a safe place. (The instructor may be next to the soldier in the same device to protect against the explosion of the grenade in which the soldier is located). A soldier with one hand presses the fuse trigger to the grenade body, with the other removes the safety pin from the grenade's fuse (most often at that moment he drops it), and after removing the safety pin, throws it in the desired direction. In FIG. Figure 3 shows the moment before throwing a grenade. In FIG. 4 presents the moment of the explosion of a correctly thrown grenade and the position of the soldier at the time of the explosion. After the grenade leaves the soldier, he has 4 seconds at his disposal. During this time (or rather, in less than one second), the soldier crouches in a protective container so that his head is below the side surface 1 (hatch 2) of the container. When squatting, the knees and buttocks require horizontal space. That is why the protective container is made in the form of a direct, circular, hollow, truncated cone. The fragments of an exploding grenade 10 fly towards a protective container, which is made of sufficiently strong material to withstand their impact. The safety of the soldier is ensured.

In Fig 5. presents the moment of the explosion of a randomly dropped grenade and the position of the soldier at the time of the explosion. In FIG. Figure 3 shows the moment before throwing a grenade. If at this moment, or at another moment, for example, when a soldier takes a safety pin from a grenade, he accidentally drops a grenade, wherever a grenade falls — on his head, shoulder, back, stomach, etc. - it will slip or slide along the hoodie 4 and along the side surface of the protective container 1 to its base. Here she will explode after 4 seconds from the moment she leaves the soldier’s hands. During this time, the soldier, as in the case when he threw the grenade correctly, will have time to sit down. In this case, the hoodie does not interfere and does not prevent the soldier from sitting down. Hoodie 4, being tailored sufficiently free, not hampering the movements of the hands and body of a soldier when throwing a grenade, simply turns out, as shown in FIG. 5 (view, if you remove the front side surface 1). The bottom 3 and the side surface 1 of the protective container are strong enough to withstand the explosion of a closely lying grenade 10.

To facilitate transportation, the protective container can be made in the form of a regular truncated pyramid, assembled from several faces. In FIG. 6 shows a hexagonal, truncated, collapsible pyramid including faces 11, inner hoop 12, screws 13 for attaching faces 11 to hoop 12, bottom 14, screws 15 for attaching faces 11 to bottom 14.

The implementation of the protective container in the form of a straight, circular, hollow, truncated cone, in which a soldier dressed in a hoodie is located, the hem of which is dressed around the perimeter on the upper (truncated) part of the cone (hatch), prevents a grenade accidentally dropped by a soldier inside the protective container and thus ensures its safety in the explosion of a grenade.
