    Description Field of the invention [0001] The present invention relates to the field of protection devices against firearms, and in detail concerns a ballistic plate.
    [0002] The present invention also relates to a method of producing said ballistic plate.
    Prior art [0003] The ballistic plates are protective devices designed to stop a shot typically fired by a firearm.
    [0004] The ballistic plates are integrated within bulletproof vests, which are worn by the user in case of need of protection, when there is the risk that the latter may be subjected to fire by one or more armed individuals.
    [0005] The ballistic protections in general, both those intended to protect an individual from a direct impact of a projectile or part of a projectile launched by a thermobalistic device such as a firearm, so those intended to protect the individual from objects or projectiles launched from a purely mechanical device, differ in two subgroups: - flexible protections; or - rigid protections.
    [0006] Flexible protections are typically made by assembling shaped panels by overlapping fabrics of similar or not similar characteristics, in order to obtain an overall non-penetrable assembly from a given projectile.
    [0007] The rigid protections are instead equipped with at least one rigid element, absolutely not foldable by hand, and apparently monolithic, capable of stopping a given projectile at speed.
    [0008] Typically, in the context of protection against bullets thrown by thermo-ballistic means, the flexible protections - also known as softarmors - are designed to protect the user from gunshots, which in general has a speed lower than 500 m / s and a very high ratio between diameter and speed. In fact, many ammunition for pistols have a diameter greater than 7 mm, and many even greater than 10 mm. Consequently the impact area of the projectile is quite high, in relation to its speed.
    [0009] Conversely, rigid protections are designed to protect the user not only from gunshots, but also from gunshots. Rifle-fired bullets can hit a target at speeds well above 500 m / s, with peaks of even over 1000 m / s. The projectiles fired from rifles, in particular when a ruled barrel has a more sharp point, and except in rare cases of bullets for anti-material rifles, the diameter of the projectile is typically less than one centimeter. Consequently the ratio between area and speed is decidedly lower. To make a comparison between the energies in play, take into account that a projectile of 44 mag, which represents one of the most powerful revolver calibers, has an energy at the mouth of about 1500-2000 J on a diameter of 10, 9 mm, while a 5.56x45 NATO projectile has an energy of about 1700 J on just 5.5 mm of diameter and a more powerful 7.62x51 NATO an energy of about 3500 J on 7.6 mm of diameter.
    [0010] The impact of a projectile against a rigid surface causes, in the case in which it is able to resist the perforation of the projectile itself, a deformation in the opposite part with respect to the point of impact which in jargon is called "trauma". This phenomenon is carefully considered in the certification standards, as a protection that resists impact without being perforated, but generates a deformation out of the normal, is not however suitable for use as personal ballistic protection.
    [0011] The standard, in any case, requires that the deformation be recorded by measuring the groove impressed on a mass of standardized plasticine to which the protection itself is previously fixed. The level of protection of ballistic plates to date is defined as follows: Level I NIJ: (.22 LR; .380 ACP) This armor protects against 22 caliber Long Rifle Round nose (40 grains) at a speed of 329 m / s .380 caliber ACP Full Metal Jacket RN (95 grains) at a speed of about 322 m / s. It's no longer part of the standards (it's too light).
    [0012] Level Ila NIJ: (9 mm; .40 S & W) Protects against bullets 9x19 mm Parabellum Full Metal Jacket Round Nose (FMJ RN) (124 grains) at a speed of about 373 m / s and from caliber .40 bullets Smith & Wesson (180 grains) at a speed of about 325 m / s. It also protects against the threats listed in Level I.
    [0013] Level II NIJ: (9 mm; .357 Magnum) Protects against 9 mm FMJ RN projectiles (124 grains) at a speed of 398 m / s and from .357 caliber bullets Magnum Jacketed Soft Point (JSP) (158 grains) at a speed of about 436 m / s. It also protects against the threats listed in levels Ila and I.
    [0014] Level NIJ Mia: (.357 Sig.; .44 Magnum) Protects against .357 caliber SIG Fiat Nose (FN) bullets (125 grains) at a speed of 448 m / s and .44 caliber Bullet Magnum Semi-jacketed Hollow Point (SJHP) (240 grains) at a speed of about 436 m / s. It also protects against most gun bullets, but also from the threats listed in the previous levels (I, Ila and II).
    [0015] Level III NIJ: (Rifles) Protects against NATO bullets 7.62x51 mm (Ammunition M80) (148 grains) at a speed of about 847 m / s. It also protects against the threats listed in the previous levels (I, Ila, II, Mia).
    [0016] Level IV NIJ: (armor-piercing rifles) Protects from .30-06 caliber Springfield M2 Armor Piercing (AP) bullets weighing 166 grains (approximately 10.7 grams), at a speed of 878 m / s. It provides at least protection from a single shot of the threats mentioned in all previous armor levels.
    [0017] The Applicant has realized that many ballistic protections, although they are able to offer excellent protections on a shot received from both a pistol and a rifle, even of large caliber, do not offer sufficient protection in the event of multiple impacts.
    [0018] The Applicant has in particular found that in the case of several shots fired closely together, most of the ballistic plates yield, or allowing splinters to penetrate or projecting towards the user at such a speed as to compromise their life.
    [0019] The object of the present invention is therefore to describe a ballistic plate capable of solving the preceding drawbacks.
    Summary of the invention.
    [0020] According to the present invention, a ballistic plate is thus realized comprising a body defined on a first axis, a second axis and a third axis, said third axis being orthogonal to said first and second axis, said ballistic plate being characterized by comprising a body of elastomeric material made of an integral element and a substantially planar metal element, said metal element being included within said body of elastomeric material so as to identify a layer of elastomeric material between said metal element along said third axis and a perimeter of external elastomeric material with respect to said metallic material along a plane parallel to the plane identified by said first axis and second axis.

    Detailed description of the invention [0036] With the reference number 100, a ballistic plate is indicated as a whole. The ballistic plate 100 extends with a body on a first vertical axis X, a second axis Y in the sense of width and a third axis Z in the sense of depth.
    [0037] The ballistic plate 100 object of the present invention comprises a main body made of elastomeric material, typically polyurethane-based, identifying a front face 103 and a rear face 104. The front face 103 is the one that in use receives the shot fired by the 'firearm or from a more general thermo-ballistic device (direction identified by the arrow F). In the first embodiment illustrated in fig. 1 and 2, the front face 103 and the rear face 104 are planar.
    [0038] The ballistic plate 100 object of the present invention further comprises a metallic element 102, which extends for the substantial part of the area of the plate itself. The metallic element 102, which in the first embodiment illustrated in fig. 1 and 2, is made from a flat plate, is embedded in the elastomeric material 101.
    [0039] The body made of elastomeric material 101 is made integrally, without solution of continuity, in such a way as to completely envelop the metal element 102. As will be described better in the following portion of description, it is possible that in the body of elastomeric material 101 are included, but also in this case it is always possible to identify a continuous closed path along the surface of the elastomeric material 101 such as to maintain the said continuity and therefore complete winding unchanged. More in detail, the construction of the plate 100 of the present invention is such that the metallic element 102 is completely surrounded by at least one portion of elastomeric material 101, so as to identify a first and a second layer 111, 112 respectively frontal and rear and lower and upper of elastomeric material 101 between the metallic element 102 and the front face 103 and between the metallic element 102 and the rear face 104 (thus, looking at the plate on a plane that includes the axis Z), and identifying, when observing the plate object of the present invention frontally as from fig. 2, a perimeter 108,109,110 of elastomeric material 101 with respect to the edges of the plate itself, preferably equal to 20 mm. The perimeter 108,109,110 is identified by a plane parallel to the plane identified by the X axis and the Y axis.
    [0040] The applicant has observed that the impact of one or more rifle shots on a metal material is such as to project splinters of the shot itself or of the metal material all around it. Thus the presence of a metallic element 102 completely incorporated within a structure of elastomeric material therefore significantly softer, advantageously allows to always leave, on each axis, a layer of elastomeric material 101 which allows to reduce the speed of the splinters projected by the impact of the projectile against the metallic element 102 without letting them out at the same time preventing the generation of a trauma on the user.
    [0041] Furthermore, in addition to the above-mentioned effects, the presence of a layer of elastomeric material also behind the metallic element 101 ensures a considerable reduction of the impact force per area unit transmitted to the user, which therefore suffers from the impact of the blow significantly less than it would suffer if that layer were not there. Therefore, even in this case the trauma is reduced.
    [0042] From studies carried out by the applicant, it has been verified that the minimum thickness 111 between the metallic element 101 and the front face 103 of the plate 100 object of the present invention, measured along the axis Z, is equal to 5 mm, and preferably it is not greater than 15 mm.
    [0043] The same studies have verified that the minimum thickness 111 between the metallic element 101 and the rear face 104 of the plate 100 object of the present invention, measured along the axis Z, is equal to 3 mm, and preferably it is not greater than 10 mm.
    [0044] These limits define a correct relationship between prevention of the risk of splinter projections anteriorly or posteriorly with respect to the metallic element 101, with respect to the total weight assumed by the plate 100 object of the present invention.
    [0045] Similarly, the applicant has found that the minimum perimeter necessary on the X-Y plane to prevent the projection of splinters laterally is equal to at least 10 mm.
    [0046] The applicant in particular has verified that the projection of splinters laterally is particularly insidious because, if projected, these splinters risk striking sensitive areas such as arms, the neck area (projection of the splinters upwards) and, if the user is crouching, even the legs.
    [0047] The perimeter of elastomeric material 102 therefore advantageously allows to reduce and almost eliminate the risk that a blow, even an incident on an end portion of the metal element 101, produces splinters coming out of the plate 100 object of the present invention.
    [0048] The studies carried out by the applicant were carried out with multiple shots of ammunition both of the pistol and of the rifle, at least in the following calibers: 7.65 mm pistol, 9x19 mm, 45 ACP, 5.56 x 45 NATO, 7.62 x 51 mm NATO, 7.62x39 mm, 7.62x54 Russian. All the impacts of the aforementioned projectiles did not produce either perforation of the metal plate or the production of splinters on the outside of the plate 100. In all cases, the thickness of the metal plate with characteristics such as austenitic steel, for example although not limited to Cr-Ni-Mo alloy, was 3-7 mm. The 3 mm limit is conservatively considered the minimum necessary for effective protection against large-caliber gun shots, for example and not limited to .50AE, .454, etc.
    [0049] The applicant has also realized a surprising effect obtained through the plate as described above. In particular, he verified that multiple firing on a reduced area, less than 10 cm2, causes neither the passage of the blow beyond the metallic element nor the projection of splinters outside the plate 100.
    [0050] Thus, with the construction as described above, a plate is made which is capable of effectively repairing the user even if it is subjected to blows fired in a very restricted area, a situation which is typical for example of a combat in the area restricted if the offending subject strikes the user wearing the plate object of the present invention with a burst of three shots, for example, which represents one of the typical operating conditions of the weapons supplied to NATO.
    [0051] To further reduce the weight of the plate 100 object of the present invention, part of the rear portion of elastomeric material 101 can be replaced by expanded polyurethane in equivalent or higher thickness.
    [0052] Observed from the front, the plate 100 of the present invention can take on a square or other shape according to the needs of the user. Fig. 2 illustrates an embodiment in which the lower portion is tapered with respect to the upper one, but this configuration must not be understood in a limiting manner.
    [0053] Fig. 3 shows a second embodiment of the plate 100 object of the present invention. This second embodiment differs from the first one in that on the X-Z plane it has a curvature such as to make the front face 103 convex and the rear face 104 concave. This configuration, according to the Applicant, ensures greater adaptability to the user's chest and therefore a more effective distribution of the impact energy of a bullet.
    [0054] Preferably, the curvature of the front face 103 has a same radius of the curvature of the rear face 104. This ensures the constancy of thickness of elastomeric material between the metallic element 101 and the edges of the plate. Thus, in the second embodiment illustrated in fig. 3, also the metallic element 101 assumes a curvature, of characteristics equal to those of the front face 103 and rear 104.
    [0055] In order to ensure greater protection for the user from heavy gunshots, for example of the caliber 30-06 or 8 mm IS, the applicant has devised a pair of further embodiments of the ballistic plate 100, shown in fig. 4 and in fig. 5.
    [0056] Said third and fourth embodiments differ from each other in that they have one, the front faces 103 and back 104 planar, as in the case of the first embodiment, while the second has the front faces 103 and rear 104 curved, and respectively a convex and the other concave as in the case of the second embodiment.
    [0057] The third and fourth embodiments have at least one additional stop layer 120, which can be in aramid fiber embedded in the elastomeric material 101 or glass or polyethylene. In particular, the applicant has found the effectiveness of the aramid material (kevlar, for example) if it is in fibrous form and not strictly woven. In this case, the juxtaposition of the additional kevlar stop layer on the face of the metal element 102 which gives onto the front face 103 of the plate 100, well blended in the elastomeric material 101, guarantees an optimal reduction of the impact speed of the projectile against the metallic material 102, and with the same overall thickness of the plate 100 along the axis Z, with the same thickness as the metal plate 102, allows the user to be repaired from significantly heavier gauges than the plate 100 without the said additional layer of stop 120 could offer instead.
    [0058] The ballistic plate 100 object of the present invention is realized with a low pressure or gravity pouring method of said elastomeric material. More precisely, the ballistic plate 100 object of the present invention is realized starting from the positioning or introduction of the metallic element 102 in a mold 200 having a first and a second shell 202 which can be opened to allow the introduction of the metallic element 102 itself to their internal.
    [0059] The metallic element 102 is positioned on support elements 203 of a size such as to define an intermediate volume on three dimensions between said metal element 102 and the inner walls of the two shells of the mold. In particular, the support elements 203 are preferably made of the same elastomeric material with which the body of the plate 100 is made. This advantageously allows, at the end of the injection or pouring, to have a more uniform structure, able to have no interruptions discontinuous material density, in order to ensure that - regardless of the area where the blow goes to impact - you always have the same action of stopping the body without risk to the user.
    [0060] Alternatively, said support elements 203, which in use then become the blocks 130-133 part of the body of the plate 100 object of the present invention, can also be made of other elastomeric or nylon materials with identical or similar density that of the elastomeric material 101; the identity of material and density ensures the maximum uniformity of the features of stopping the fired shots.
    [0061] At this point a low-pressure injection step or casting step of the said elastomeric material takes place in the said intermediate volume, and a waiting step for the solidification of the said elastomeric material. The elastomeric material is poured or injected through one or more injection holes 201 present in the shells 202. The low pressure casting or injection advantageously allows to have a greater production economy. Furthermore, the applicant observed that high-pressure injections, especially with plates of reduced thickness, cause a deformation of the metal plate itself which can compromise the overall protection efficiency of the plate. The casting is advantageously carried out by tilting the plate so as to prevent the formation of bubbles, according to a known technique. If the additional stop layer 120 is present, these are juxtaposed to the metallic element 102 and held therewith by the support means 203.
    [0062] In fig. 8 and in fig. 9 shows respectively a side section view of a variant of the mold for the production of the plate object of the present invention and a perspective detail of the support means 203 object of the present invention.
    [0063] In particular, in fig. 8 there is a support means 203 of a truncated pyramid shape which is introduced above and below the metal element 101 in such a way as to keep it centrally positioned within the volume of the mold, leaving enough space to allow the elastomeric material to be cast.

    [1]
    [0064] As shown in fig. 9, in fact, the support means 203 in this case has a body having a bottom wall 203a in the tapered portion of the truncated pyramid, which in use is adapted to rest respectively on the bottom and on the upper portion of the shells 202. [0065] From the bottom wall 203a two inclined lateral walls 203c depart which are opposite to each other and each having a portion of a lateral wall perpendicular to the bottom wall 203a. Between the two portions of lateral wall perpendicular to the bottom wall 203a there is a recess 203b with a planar bottom, which has a terminal wall parallel to the bottom wall 203a. The thickness of the terminal wall, and therefore of the recess 203b, is at least equal in size to the thickness of the metal element 101, possibly slightly thicker, so as to allow its introduction and fixing. Also in the latter case, the support means 203 is preferably made of the same elastomeric material which is subsequently cast into the mold, although the possibility remains of realizing the support element 203 with other characteristics, particularly of density, as previously described. [0066] In summary, the ballistic plate created as described above combines characteristics of strength with lightness and ease of wearing characteristics, guaranteeing optimal protection for the user from a great variety of shots, fired from both guns and shotguns, preventing not only that the blow passes, but also preventing the formation of splinters towards each side, and preventing gusts of multiple shots fired in very restricted areas from leading to a puncture of the plate itself with an impact of the blow on the user's body. [0067] Finally, it is clear that additions, modifications or variations, obvious to a person skilled in the art, can be applied to the ballistic plate of the present invention, without thereby departing from the scope of protection provided by the annexed claims. claims
