Description

AREA OF INVENTION

The present invention relates to the area of armor against ordinary and armor penetrating Firearms and their debris and aims at deployment a light armor, which is suitable for a variety of purposes is how B. for the production of protective clothing or the construction of closed areas with opaque or clear armored wall sections and the same.

In particular, the present invention is concerned with a light armor arrangement as defined in the preamble of the appended claim 1. Such arrangements are for example from US-A-3 380 406 or US-A-2318301 and are based on the observation that when an inclined body put in the path of a firearm bullet that the latter is asymmetrical forces is subjected, which cause the projectile from its Trajectory in the direction of that formed between the trajectory and the body obtuse angle is deflected. In addition, the projectile can be disassembled and all of this means that the projectile either through the body or stopped by a back body can be.

The sloping front body of this Arrangement consists of a high-modulus material, such as. B. glass or Ceramics in US-A-3 380 406 and metal in US-A-2 318 301.

BACKGROUND THE INVENTION

There is a widespread need for protected locked Areas with clear wall sections resistant to firearms, with typical examples showcase in riot-prone Areas, armored vehicle windows, spasm, aircraft cockpits, Helicopter windows, pulpits for a tank commander’s post, etc. According to the state of the art it is usual, for such Laminated glass plates, for example 11 to 40 mm thick or to use more by the action of their mechanical properties against the penetration of projectiles of different types of firearms resistant are. However, such plates are very heavy and weigh approximately 3 to 4 times opaque armor, and are too expensive and therefore for many purposes cannot be used. There is therefore an ever increasing Need for a light, transparent armor material.

There is also a wide-ranging one Need for a deformable material resistant to firearm projectiles, for example for the production of protective clothing, bulletproof tarpaulins and the like.

There is also a need for a hardened lightweight, opaque armor against firearms.

It is the task of the ending, all those needs to fulfill.

GENERAL DESCRIPTION OF THE INVENTION

Thus, according to the invention, one against that Penetration of firearm bullets resistant light armor arrangement provided as defined in appended claim 1.

The terms "front body" and "rear body" refer only to the relative positions of the two bodies and do not include an additional, non-inclined front plate as shown in FIG 4 out.

If desired, the armor arrangement can according to the invention two or more front bodies include.

That according to the present invention Light, weak, low modulus material used can be see-through or opaque and be either soft or hard. Where outside of the two between the Trajectory of the firearm projectile and the surface of the at least one front body trained complementary Angle the upper angle is obtuse and the lower one is pointed, it will Firing gunshots shot distracted above. In contrast, where the bottom angle is blunt and the upper one is pointed, an impacting firearm projectile down distracted.

In the case of a transparent front body is also the back body preferably transparent. A clear front body can made of PMMA (acrylic glass), various synthetic materials, such as z. B. polycarbonates, epoxy resins, PVC and the like exist.

An opaque front body can be made of a heavy-duty clothing material, such as. B. Kevlar ^TM , Spektra ^TM and various epoxy materials and the like exist. Such materials can be used in a soft, deformable form or in a composite-hardened form, for example impregnated with a suitable polymeric material which is hard after setting.

The front body in the lightweight according to the invention Armor assembly can be a monoblock, i. that is, from only one single material. Alternatively, it can be laminated and can consist of two or more layers of the same material or be a composite and can be made up of two or more layers different Materials exist. In any case, there will be adjacent layers glued or cemented together in a suitable manner.

If desired, the front body in a light pan according to the invention Cerification arrangement forming laminate or composite block, the individual layers may be inclined with respect to the expected trajectory of an incoming firearm projectile.

In use, an incoming firearm bullet penetrates across the at least one front body and if it emerges from them either intact or broken, dependent from the inclination of the front body distracted either upwards or downwards with respect to the trajectory and does not penetrate the back body. In the case of a thick one front body can distract the projectile become without at all the back body hold true.

It can thus be seen that according to the invention the required impact resistance of the back body far is less than in the prior art. For example in the case where the body is a see-through wall or sheet of glass, the weight of which per unit area the half of that of a body according to the state of the art, which is the full impact an incoming firearm bullet must resist.

SUMMARY THE DRAWINGS

For a better understanding The invention will now be described with reference to the accompanying drawings described in which:

1 Fig. 3 is a schematic diagram showing the manner in which the invention works in the case of only a front inclined body made of light material;

2 Figure 4 is a similar representation for two consecutive inclined front bodies made of light material;

3 a schematic representation similar to that of 1 wherein the front body is a composite body; and

4 is a schematic representation of a further embodiment of the invention.

DESCRIPTION THE SPECIFIC EMBODIMENT

In 1 an arrangement is shown schematically, which is an inclined light front plate 1 and a vertical back plate 2 having. An arrow 3 stands for the incoming firearm projectile and the trajectory of the projectile 3 is, as can easily be inferred from the figure, substantially perpendicular to the vertical rear plate and of those at the point of intersection of the projectile's trajectory 3 with the plate 1 trained two angles, the upper angle is obtuse. As a result, once the projectile 3 the plate 1 has penetrated this as in 4 shown, either as a whole or disassembled upwards and either does not hit the vertical rear panel at all 2 or is otherwise easily intercepted by them without penetrating them.

In the schematic in 2 Embodiment shown, in which similar components are denoted by the same reference numerals, are two different inclined transparent front plates 1 and 5 intended. In this arrangement the incoming firearm bullet 3 through the plate 1 in the at 6 illustrated way distracted where it is still in position to the second plate 5 to penetrate where it turns into the at 7 direction is deflected, the end result similar to that in 1 is.

At the in 3 schematically illustrated embodiment of the invention, which is substantially similar to that of 1 , with similar components again being identified by the same reference numerals, is the plate 1 with layers 8th and 9 of a different light material coated. In essence, this embodiment operates in a similar manner to the embodiment of FIG 1 ,

In the 1 The illustrated embodiment includes a front plate 10 , a light block of material 11 , which consists of a variety of inclined plates 12 exists, which are glued or cemented together, and a vertical rear plate 13 , Passing through the block 11 becomes the firearm projectile 3 through each of the plates 12 distracted, which it hits on its way, therefore does not deflect and penetrate the rear plate 13 ,

In each of the above embodiments can the light front and rear panels are transparent according to the requirements or be opaque.
