Abstract

Improved bullet-proof device made up of a variable number of aramide or similar material band layers (1), partially overlapped in a preferably parallel way, with the peculiarity that the successive band layers are preferably arranged in alternate horizontal and vertical positions, intercrossed or interlaced or in various combinations with other materials Fig. 5).

The invention is applicable to bullet-proof vests or to people or objects that must resist all types of impact, in order to minimize the effects caused by such impacts, specifically the decrease in the trauma effect, with ideal constructuve and utility contributions.

Description

The purpose of this request for a Patent is an improved bullet-proof device that provides for the function for which it is intended various advantages to be detailed later on, apart from others inherent to its organization and constitution.
More specifically, a bullet-proof device has been designed in the invention that has noteworthy advantages and novelties compared to the present bullet-proof devices or materials, the structure of which can be applied both to the manufacture of bullet-proof vests as well as to many other applications, such as cars, helmets and others, as this invention presents maximum resistance to projectiles, weapons and, in short, to all types of impact, together with many other advantages which will be described later on.

HISTORY

At present and as a reference to the state-of-the-art, it should be mentioned that the bullet-proof vests and devices of today are made of aramide plates and other materials, joined together by resin forming a sandwich type group.

DESCRIPTION OF THE INVENTION

The improved bullet-proof device, purpose of this invention, is made up of a variable number of aramide or similar material band layers, partially overlapped in a parallel way, with the peculiarity that the successive band layers are alternately arranged in the horizontal and vertical positions, respectively, crossed and intercrossed, or forming various combinations with other materials. Thus the invention has multiple performance variants, such as the formation of the device based completely on intercrossed bands; unwoven bands (cut from clothing, etc.); stiff bands and layers; bands and a structure that provides stiffness to the set; a materials formed by intercrossed layers where each layer has individual layers and band parallelism with bands already crossed, as well as any other possible combination.
The device of the invention has better anti-trauma protection, that is it reduces the deformation depth of the impact, as the special arrangement of its intercrossed band layers not only do not let the projectile or similar pass through but also create a mesh or net that traps the projectile and does not let it penetrate the material. Therefore, as the projectile advances it meets with more and more resistance during its path and the crossed material acts as a brake, because what really stops the projectile is the stress made by the most perpendicular threads to its path, produced on a large scale and geometrically multiplying the efficiency of the device.
One of the main advantages of said device is that it does not lose its bullet-proof qualities with the first shot, due to the fact that, as described in the above paragraph, only two bands touch, one vertical and the other horizontal, in such a way that the device keeps on maintaining its properties for more impacts as the deformation is precise and does not extend through the surface of the device, thus increasing the performance and durability of the device.
Furthermore, it should be mentioned that as the material is based on bands, it is completely moldable as opposed to the stiff plates of which the present bullet-proof vests and devices are made. Therefore, the convenience when making bullet-proof vests or other clothing by weaving bands is much greater for the persons who makes them and for the person who has to wear this clothing for long periods of time, apart from being flexible and light thanks to its mentioned constitution and design.
In order to complement the description which follows and to help with a better understanding of the characteristics of the invention, this descriptive report includes a set of drawings in which the most significant details are represented in an illustrative but not limiting way.

BRIEF DESCRIPTION OF THE DRAWINGS

Figures 1 to 5 show both performance alternatives of the invention.

PERFORMANCE EXAMPLE DESCRIPTION OF THE INVENTION

In view of the figures commented above and in accordance with the numbering used, various examples constituting different performance alternatives of the invention can be seen. The invention consists of an improved bullet-proof device made up of aramide or similar material band layers -1-, partially overlapped in a parallel way so that the successive band layers are arranged alternately in the horizontal and vertical positions and are intercrossed, as shown in figure 5. They could also be interlaced or in various combinations with other materials, as shown in figures 1 to 4. In all cases, the advantages described above are obtained as regards all types of impact, as well as many other advantages arising from the physical, constructive and functional properties of each performance variant that this invention can offer.
Thus, as an example, in figure 1 a performance variant of the invention can be seen, in which stiff layers -2- have been added to the previous band layers -1-.
In figure 2 another performance variant of the invention is shown in which the band layers -1- are included between two groups of stiff layers -2-.
Figure 3 shows another performance variant of the invention in which stiff layers of different materials -2-2'-in various combinations have been added to the band layers.
Figure 4 shows another performance variant of the invention in which an individual layer -3- with bands -1-previously intercrossed appears.
