Description

[Detailed description of the invention] The present invention relates to a method for manufacturing a bullet-proof bullet capturing device, and a method for manufacturing a bullet-proof bullet capturing device. Concerning the application of bullet capture devices.

In army combat, soldiers, especially infantry, are exposed to gunfire and/or radiation. It is often necessary to hide within the shortest possible time.

Banks and embankments made as small as possible are also used for this purpose.

If you have a little more time, make an artificial shelter - 1, especially a breastplate, or a breastplate in the front. The attached manhole is dug. However, it is only a temporary shelter. At times, this may be too difficult, especially in hard, stony and/or rocky areas. It takes too much time.

The ramparts, which have stones placed all over them, have an additional drawback: they can put your teammates at risk when exposed to sunlight. be exposed to danger. Other bullet capture devices, such as those at shooting ranges, also protect against ricochets. are rarely optimally equipped, and when they are, they are very spending money.

The DE-C7583B from the last century is a box filled with a paste-like substance. It describes a bullet capture device consisting of. This viscous substance is, for example, Consists of a mixture of asphalt, tar, pitch, loam and sand; The material can be remelted for bullet recovery. This bullet capture device is complicated. The production cost is high, and it is suitable only for fixed equipment. D　E　-C75 The bullet capture device described in 83B cannot be used in mobile combat.

The object of the invention is to provide a bullet capture device of the type detailed at the outset, namely at low cost. It can be produced quickly, does not ricochet, provides good military shielding, Meets strict safety requirements for bullet capture devices for shooting range applications .

Regarding the method, the problem is solved according to the invention as follows. That is, Contains cellulose pulp made of superabsorbent material contained within an expanding, sealed interior chamber. , at least one element consisting of a water-permeable, tear-resistant cover on all sides; Place the cartridge in the area where the bullet capture device is to be fabricated and insert it into the swellable element. Water is supplied until the mixture is saturated, thereby forming a gel. of the cover Extensibility is such that even when the pulp is completely saturated with water, it still has some strength. Ku. Particular embodiments and developments of the invention are the subject of the dependent claims.

Cellulose pulp, which consists of so-called superabsorbents, is generally used for infants and adult incontinence. Used in the manufacture of sanitary products for water protection devices or water protection devices. dry Superabsorbent materials can be in the form of powders or fibers, and when they come in contact with water, they They increase in weight and volume many times over a very short period of time, forming a gel-like mass. . IKg superabsorbent material can absorb up to approximately 800Kg of water and has a corresponding Expands to a smaller size. Superabsorbents are also known by the abbreviated name SAP-s. However, polymers with a high degree of absorption, such as those based on acrylic acid It is the body.

Superabsorbents may have support materials other than cellulose pulp, such as non-woven fabrics. It is a well-known fact that this is not the case. For easy cellulose pulp or re- All of these variants which also consist of raw fiber pulp are meant. this They are of particular importance for economic and ecological reasons.

Superabsorbents, or gels, that are completely saturated with water are made mostly of water. ing. For example, a bullet fired from a personal attack weapon can travel very quickly underwater. be stopped. In the case of flares, there is always a risk of fire; , the shell is immediately quenched.

When the bullet hits the element, a strong blast wave is created.

For this reason, it is possible to attenuate this as well without causing any damage and for a short period of time. It is particularly important that it can be absorbed after some time. Otherwise, it is a gel-like super absorbent material. The elements would be torn into pieces by the blast waves.

Depending on its velocity, weight, and diameter, the bullet penetrates the element to different degrees. It's coming. The general penetration depth is about 20 cm at most. However, cheap For all the above reasons, the bullet capture device shall have a depth of at least 50 cm. It is necessary to It is a circular or rounded shape having several intermediate chambers. This is especially important when using elements.

Therefore, an element consisting of a bellows-shaped folded cover is advantageously used. be done. Upon absorption of water, these elements expand into essentially rectangular solids. , giving little space for an intermediate chamber.

To prevent the elements from expanding before use, they are Store and store in groups in water-impermeable protective films that can be torn apart. It is advantageous to transport the In addition to the tearing means, this protective film also has 1 One or more carrying handles can also be provided.

The cover of the element is preferably made of water-permeable non-woven, woven, knitted or plastic fabric. It consists of formed into a non-woven fabric, woven, knitted or bonded Minerals, polypropylene, polyester and/or Also, polyamide fibers have very good tear resistance and remain strong after absorbing water. even has it.

i.e. using the DuPont product PULPLUS. Advantageously enhanced by thermoforming loin fibers at many points to bond them together be able to. However, be careful not to affect the extensibility of the cellulose pulp. At the very least, it must be ensured that the extensibility is not significantly inhibited. No.

The extensibility margin of the water-saturated cellulose pulp cover is preferably small. It is at least 10%. As mentioned earlier, this elongation occurs when the bullet enters. It helps to capture and attenuate the blast waves caused by the explosion. Extensibility is e.g. Unfinished bellows, stretchy knitted fabrics, or relatively large bulges. This can be ensured by forming, etc. However, bullet capture devices do not allow the blast wave During the temporary expansion to capture and attenuate the motion, one bullet flies at the same time. However, it must be designed so that it cannot be penetrated.

Additionally, bullet holes are prevented from tearing the cover during expansion. There must be.

The dry elements are preferably connected or separable. are connected to each other. If one discrete element is not used enough, It is easier to stack connectable elements to form a bullet capture device.

Drying elements that are already connected to each other in multiples may be removed if they are separable. It is especially easy to stack them to form a bullet capture device if they are connected in a similar manner.

Therefore, the necessary elements can be made from folded aggregates or rolled It can be used separately from the In this way, in the rose element Instead, the entire collection or roll is covered with a water-impermeable plastic cover. can be protected.

The element is divided into several chambers by longitudinal and/or transverse partitions. It can be divided into. These bulkheads can be sewn, knitted or welded. It is created by searching.

According to a first aspect, the bullet capture device manufactured by the method of the present invention is Used as a combat shelter, especially as a temporary shelter.

Stacked or rolled drying elements are extremely light in weight and Since it does not take up much space, it can be used with a protective cover to protect it from moisture. , and can also be carried in small combat formations.

What is needed to create a temporary combat shelter can be absorbed in a few seconds. It is just the water that is accommodated and the volume expands accordingly. Even if the terrain is changed by human power Protection of areas unsuitable for digging until a combat unit corps is formed Objects can be created within minutes.

For example, adding earth or sand to a shelter made according to the invention is particularly It's advantageous. This is not only because the gaps are well filled, but also because it is psychologically important. The purpose is to increase the sense of security of the soldiers.

Temporary combat shelters are quite sufficient for short-term occupations. longer term When occupying a country, you can create a temporary combat center by carrying out regular earth digging operations. - can protect and reinforce.

According to a second aspect, a bullet capture device made according to the invention can be used indoors or outdoors. It can be used either at the target face of the firing range or behind the target. Ru. The bullet capturing device according to the present invention can be used when the allotted number of shots has been completed or when the bullet is damaged. In case of an accident, it can be easily replaced. Therefore, the shooting range The bullet capture device preferably consists of several bullets with a final weight of about 20-30 kg. The elements to be replaced can be easily removed one by one. It is now possible to do so. The bullets that have entered the chamber will be recovered after taking the prescribed measures. can do.

The bullet capture device according to the invention can be used both in military combat and on the firing range. This also has the advantage that no bullet ricochet occurs.

For some embodiments of the invention, which are also the subject of dependent claims, reference is made to the accompanying drawings. This will be described in more detail below with reference to the following.

The bullet capture device 2 shown in FIG. , serving as a temporary combat shelter for two infantrymen.

The bullet capture device 2 consists of elements 14 arranged laterally and rearward to each other, The element contains water-swollen superabsorbent material. In this case, element 14 The geometric dimensions of are different. This involves placing the joints behind each other. There is an advantage that there is no required force.On the other hand, if these are combined to form two columns If you do not plan to form a unit, use two different types of drying elements. I have to carry 14 (I have to accept the drawback of 1).

As an example not shown, elements 14 are of comparable dimensions, but at least It is also possible to shift the position laterally. Shift height and position It is preferable to place something under one row, for example loose soil material8. It is a good idea to

The bullet capture device 2 can also be designed to have half this height. At that time, Ayumi Soldier 4 is only protected when his body is in a horizontal position.

Furthermore, soil material 8 or sand is packed into the joint and/or on top of the bullet capture device 2. It is preferable to cover it. This will only increase safety and the sense of security for infantry 4. Instead, it camouflages the bullet capture device. A battle with a temporary character For shelters, place a heap of dirt or sand on top of the entire bullet catcher. can be done.

The bullet 10 lodged within the element 14 is shown with extremely exaggerated dimensions. There is. This bullet was stopped after reaching a penetration depth of approximately 15 cm and is now an electric It is loosely held and stopped in the expanded mass of the ment 14.

In the dry state, the folds 12 of the bellows-shaped element 14 are still visible. It is visible. These folds are designed to attenuate and absorb blast waves. Guaranteed to have 5% extensibility.

Figures 2 and 3 show several layers of non-woven fabrics stacked on top of each other to which superabsorbent materials have been applied. This diagram illustrates the element 14 that is made of. When it comes to its features, it's super Non-woven fabrics made of absorbent material are cellulose pulp containing dispersed superabsorbent substances It corresponds to 16. Therefore, non-woven fabrics made of superabsorbents and those containing superabsorbents The reference number 16 is used to represent both cellulose pulp and cellulose pulp. Continuously The nonwoven fabric stacked on top is a tear-resistant synthetic water-permeable knitted fabric. They are kept together by a cover 18 made of. Non-woven fabric made of super absorbent material dries , and therefore has not yet absorbed any water.

The two halves of the cover 18 are stacked together to prevent water leakage. An annular edge 20 is formed by two outer surfaces.

The upper lip 20 is made relatively wide, and the handle 22 shown in dotted lines is cut out. You can make it. Of course, you can add some handles 22, small holes, tabs, etc. Can also be done.

Overall, the elements 14 have a flat shape, can be stacked, and have a small It can be transported with only a small amount of space required. After absorbing water, the cover 18 Mento 14 swells up to the point where it becomes almost round. some round elements , placed behind each other to form a dense spherical bag, it becomes an extremely good bullet catching device. The place is completed.

Figures 4 and 5 show a cover filled with cellulose pulp 16 containing superabsorbent material. 18 represents the configuration of element 14 before and after water absorption. lying on the ground The element 14 has a bellows-shaped folded side wall 26, which absorbs water and expands to its full capacity.

Therefore, the cover retains approximately 12% residual extensibility, which allows the bullet to enter the It is useful for catching and absorbing the blast wave caused by the explosion.

Additional, e.g. 2 to 6, carrying tabs (not shown) are provided on the top of the cover 18. You can also

The design of the bullet capture device 2 according to FIG. 1 is based on the element 14 according to FIGS. 4 and 5. I'm there.

The device according to FIG. It consists of elements 14 and is arranged on the ground 28. mutually between the plurality of covers 18 The edges 20 that stick together have small holes and can be connected by appropriate means. It is Noh. The hook 30 has already been inserted into one of the two adjacent small holes 30. Good too.

The sheets of elements 14 according to FIG. 6 may be stacked in layers behind and on top of each other. The edges 20 of the two sheets that do not overlap each other and the surrounding area is preferably filled with, for example, earth or sand.

Before use, the interconnected elements 14 are rolled or folded. can be done. It saves space and eases transportation, making it suitable for rapid deployment. ing.
