[0001] The present invention relates to an absorption projectile arrester.
[0002] More specifically, the invention concerns an absorption projectile arrester of the
cartridge type, particularly suitable for the 3^ class firearms (up to 3000 J).
[0003] During the recent years, many solution have been proposed, also and particularly
by the same Applicant, in order to try to realize projectile arresters suitable for
the different requirements.
[0004] Among the requirements, it particularly important the one concerning the safety.
[0005] Further, the projectile arrester provided according to the present invention realizes
an extremely easy solution under a constructive point of view.
[0006] Another object of the present invention is that of providing a projectile arrester
easily transportable, particularly, although not exclusively, within ISO containers.
[0007] It is a further object of the present invention that of providing a projectile arrester
that avoids the harmful creation of lead vapors in the environment, due as it is known
to the impact of the projectiles.
[0008] This and other results are obtained according to the present invention providing
a technical solution to realize a projectile arrester of the so called cartridge type,
wherein in order to decelerate the projectiles a material is employed that does not
permanently deforms and that does not tears for the passage of the projectiles through
it.
[0009] It is therefore specific object of the present invention an absorption projectile
arrester of the type insertable within a container and having all the walls, except
the wall faced toward the shooters, made up of ballistic sheet, the surface of the
projectile arrester faced toward the shooters being made up of a rubber shield, behind
the shield granular material being provided, and between said granular material and
said shield means for sustaining the thrust of the granular material and a layer allowing
the passage of the undeformed projectiles being provided, said layer does not tear
or permanently deform after the passage of the projectiles.
[0010] Preferably, according to the invention, said ballistic sheets have a total inner
lining.
[0011] Still according to the invention, said projectile arrester is contained within an
ISO container having dimension normally transportable.
[0012] Always according to the invention, said shield faced toward the shooters is realized
by para rubber and is perimetrically fixed.
[0013] According to a first embodiment of the projectile arrester of the invention, said
means for sustaining the thrust of the granular material are made up of a plurality
of hardened steel vertical elements, fixed to the ballistic sheets of the floor and
of the roof, and said layer is made up of a plastic diaphragm transparent with respect
to the projectiles and realized with a material that does not tear for the passage
of the same undeformed projectiles, i.e. the projectiles that have not previously
impacted against other structures of the projectile arrester, and the closes again
after the passage of the projectile.
[0014] According to a further embodiment of the projectile arrester according to the invention,
said means for sustaining the thrust and said layer are made up of a plurality of
blocks of plastic material with a very high ductility, provided in such a way that
they close all the surface faced toward the shooters, and that allow the passage of
the projectiles without cracks and able to sustain the horizontal thrust.
[0015] Still according to an embodiment of the projectile arrester according to the invention,
said means for sustaining the thrust and said layer are made up of a layer comprised
of pressed and glued elastomeric granular material blocks.
[0016] Further according to the invention, said means for sustaining the thrust and said
layer are made up of rubber vertical elements.
[0017] Still according to the invention behind said back wall of the projectile arrester,
an inspection passage reachable by the operators can be provided.
[0018] Further, according to the invention, between said means for sustaining the thrust
of the granular material and the back wall of the projectile arrester ballistic sheet
transverse walls can be provided.
[0019] According to the invention, said granular material placed behind the front shield
is elastomeric granular material.
[0020] The present invention will be now described for illustrative, but not limitative
purposes, according to its preferred embodiments, with particular reference to the
figures of the enclosed drawings, wherein:
figure 1 is a plan view of a first embodiment of the ballistic projectile arrester
according to the invention;
figure 2 shows a particular of the ballistic projectile arrester of figure 1;
figure 3 is a section view of the ballistic projectile arrester of figure 1;
figure 4 is a section view of a second embodiment of the ballistic projectile arrester
according to the invention;

figure 6 is a section view of a third embodiment of the ballistic projectile arrester
according to the invention;
figure 7 shows a particular of the projectile arrester of figure 6;
figure 8 is a perspective view of a further embodiment of the projectile arrester
according to the invention; and
figure 8 is a perspective view of a further embodiment of the projectile arrester
according to the invention.
[0021] Making first reference to the figures 1-3, it is shown a ballistic projectile arrester
1 according to the invention that, in the embodiment shown is depicted included within
an ISO container, having normally transportable dimensions.
[0022] Said projectile arrester 1 can be installed within already existing rooms.
[0023] As already said, it can be contained in any metallic structure having a rectangular
or cylindrical shape.
[0024] The projectile arrester 1 according to the invention provides walls 2 made up of
ballistic sheet with an inner total lining, except for the surface faced toward the
shooters.
[0025] Said surface faced toward the shooters is closed by a para rubber shield 3, perimetrically
fixed.
[0026] Within said shield 3, on the surface faced toward the shooters, a plurality of vertical
elements 4 is provided, realized by hardened steel, fixed to the ballistic sheets
2 of the floor and of the roof.
[0027] The vertical elements are suitable to sustain the thrust of the elastomeric granular
material 5 provided behind them.
[0028] Between the vertical elements 4 and the elastomeric granular material 5, a plastic
diaphragm 6 is provided, having features making it "transparent" with respect to the
projectiles striking it with a direct trajectory.
[0029] On other words, said diaphragm 6 allows the passage of the projectile without any
deformation of the same along the thickness of the diaphragm, without being torn and
closing again after the passage of the projectile.
[0030] The granular material 5 provided behind said diaphragm will have a suitable thickness
in order to absorb the energy of the projectiles shoot by the abovementioned type
of arms, corresponding to 3600 J.
[0031] As it will be easily understood by those skilled in the art, the solution proposed
according to the present invention is particularly advantageous since allows to absorb
projectile of the third class firearms without deforming the projectiles, thus avoiding
the problems connected with the production of harmful vapors as occurs in the traditional
projectile arresters.
[0032] Making reference to the figures 4, and 5 and 6 and 7, the parts of the projectile
arrester corresponding to the parts of the preceding embodiment are indicated by the
same references.
[0033] Observing first the figures 4 and 5, it can be noted a solution wherein the structure
realized in the preceding embodiment by the hardened steel vertical elements 4 and
by the plastic diaphragm 6 has been replaced by a plurality of blocks 7.
[0034] Said block 7 are realized by plastic material having a very high ductility. The features
of the material by which the blocks are realized are such that they allow the passage
of the projectile without any damage for the projectiles.
[0035] The blocks 7 are provided in such a way to completely close the front surface, faced
toward the firing trajectory from the firearms.
[0036] Further, they must be able to sustain the horizontal thrust imposed behind by the
granular material 5.
[0037] Coming now to observe figures 6 and 7, it is shown a further embodiment, structurally
very similar to the embodiment shown in figures 4 and 5.
[0038] In this case, instead of the plastic blocks 7, blocks 8 are provided realized using
pressed and glued elastomeric granular material.
[0039] Also the material employed to realize the blocks 8 must allow to the blocks to have
the mechanical features previously indicated, so as to realize a stopping structure
for the projectiles having the abovementioned advantages.
[0040] Referring now to figure 8, it is shown a further embodiment of the projectile arrester
according to the invention, structurally equal to the ones previously described, with
the sole difference that in this case instead of the steel vertical elements 4, rubber
elements or supports 9 are provided.
[0041] The other technical features of the projectile according to the invention correspond
to those of the preceding embodiments, so that the same references are used.
[0042] Above the elastomeric granular material 5, as well as in the previous embodiments,
ballistic sheet baffle plates 10 are provided.
[0043] The embodiment illustrated in figure 9 in somewhat different with respect to those
previously described. In this case too, for the corresponding parts, the same references
have been used.
[0044] In the solution shown, a granular material 5' is employed that allows to reduce the
thickness of the absorption mass.
[0045] In this it is possible to provide behind the mass of granular material an inspection
passage reachable by the door 11.
[0046] In this solution, it is not necessary to provide the baffle plates 10.
[0047] Each one of the described solutions making reference to the different figures can
provide transverse walls between the single elements 4, 7, 8 or 9 and the back wall
2 of the projectile arrester in order to realize many little rooms of granular material
5 or 5'.
