Description
BULLET TRAP FOR SHOOTING RANGES
The present invention relates to a bullet trap for shooting ranges.
Nowadays several different kinds of bullet trap for shooting ranges are known, and they are known in the jargon as 'backstops'.
Backstops not only have the task to cancel out the energy of the bullet. They also have to simultaneously provide for two other important functions: protecting the environment, and ensuring healthy working conditions for the employees and users.
A first type of such bullet trap are steel backstops, in which the principle is to brake the bullets by allowing them to slide on steel plates that are inclined with respect to the path.
By grazing these plates, the bullet is braked, but this brings problems and consequences, which are constituted by the shattering of the bullet, the production of highly-polluting lead dust, and the creation of noise pollution.
Such a backstop is known in various different configurations, i.e. ramp backstops, Venetian blind backstops, involute-shaped backstops and wells backstops, but none of these is preferable insofar as it improves the above-mentioned drawbacks, which all of these have in common.
A second type of such bullet trap is the backstop made of recycled rubber, i.e. rubber obtained from tires, conveyor belts, blocks of swarf and the like.
These systems are effective only for a very short period of time, since the rubber deteriorates rapidly and, in breaking up, it does not provide an efficient and long-lasting retardation of the kinetic energy of the bullet.
The shattered rubber, thus transformed, becomes highly flammable.
Furthermore, the separation of the lead of the bullets from the rubber, for the separate disposal of these materials, is an operation that effectively cannot be achieved without involving very high costs.
In general the types of bullet trap mentioned above do not allow the recovery of the bullets in a substantially integral state.
The aim of the present invention is to provide a bullet trap for shooting ranges which is capable of improving the known art in one or more of the above mentioned aspects.
Within this aim, an object of the invention is to provide a bullet trap by virtue of which the shattering of the bullet and the release of lead dust are greatly reduced, if not eliminated.
Another object of the invention is to provide a bullet trap that does not require costs for the separation of materials in order to recover the lead of the bullets.
Another object of the invention is to provide a bullet trap that makes it possible to recover the bullets in a substantially integral state.
Another object of the invention is to provide a bullet trap by virtue of which the separation of the bullets collected does not require any special labor.
A still further object of the present invention is to overcome the drawbacks of the known art in a different manner to any existing solutions.
This aim and these and other objects which will become better apparent hereinafter are achieved by a bullet trap for shooting ranges according to claim 1, optionally provided with one or more of the characteristics of the dependent claims.
Further characteristics and advantages of the invention will become better apparent from the detailed description that follows of a preferred, but not exclusive, embodiment of the bullet trap according to the invention, which is illustrated for the purposes of non-limiting example in the accompanying drawings wherein:
- Figure 1 is a schematic side view of a bullet trap according to the invention;

- Figure 3 is a schematic view from above of the bullet trap according
to the invention;
- Figure 4 is a partially exploded side view of a detail of the bullet trap according to the invention;
- Figure 5 is a schematic transverse cross-sectional view of a part of the detail in Figure 4;
- Figure 6 is a schematic cross-sectional side view of another detail of the bullet trap according to the invention;

- Figure 8 is a view from below of the detail in Figures 6 and 7;
- Figure 9 is a partially exploded cross-sectional side view of another detail of the bullet trap according to the invention.
With reference to the figures, a bullet trap according to the invention is generally designated by the reference numeral 10.
Such bullet trap 10 comprises:
- a deflection chamber 11 with converging inclined walls 12, 13, 14,
15, with a front opening 16 for bullet entry and a rear slot 17 for bullet exit,
- means 18 of wetting the inclined walls with cooling liquid,
- a liquid curtain 19 arranged so as to affect the front bullet entry opening 16,
- a rear tubular body 20 with a vertical axis, for dissipation of the kinetic and thermal energy of the bullets, which is connected to the deflection chamber 11 by way of the rear bullet exit slot 17,
- means 21 of automatic recovery of the bullets from the cooling liquid,
- a collection tub 23 for the cooling liquid 24.
The deflection chamber 11 comprises four inclined walls, i.e. a triangular upper wall 12, a likewise triangular lower wall 13, and two opposite trapezoidal side walls 14 and 15.
The inclined walls 12, 13, 14 and 15 define a deflection chamber 11
that is substantially shaped like a truncated pyramid, with a rectangular front bullet entry opening 16 and a likewise rectangular rear bullet exit slot 17, which extends predominantly vertically.
In the embodiment described herein by way of non-limiting example of the invention, the means 18 of wetting the inclined walls 12, 13, 14 and 15 comprise a pump assembly 22, which is arranged so as to draw a cooling liquid 24 from a collection tub 23, and is adapted to dispense such liquid, pressurized, filtered through a filter 25, by way of a first upper manifold 26, fed by means of corresponding first pipes 28, which is designed to dispense liquid against the upper inclined wall 12, from which the liquid then descends, inundating the side walls 14 and 15 and the lower wall 13.
Such wetting of the walls 12, 13, 14 and 15 has the result that it slows down the bullets before they impact with a wall, plus it cools the bullet proper and cools the walls proper.
The liquid curtain 19 comprises a second upper manifold 27, which is arranged above the front opening 16, is fed by the pump assembly 22 by way of corresponding second pipes 29, and extends for the entire width of the front opening 16.
The second upper manifold 27 is provided with two liquid intakes 31 and 32, each one of which is connected to a corresponding pipe 29, an intake chamber 33, where the liquid enters under pressure with a vortical motion, and an underlying flow stabilizing partition 34.
Such flow stabilizing partition 34 is constituted for example by a plate with through openings in a honeycomb pattern.
The liquid descends, by way of the flow stabilizing partition 34, with a laminar flow into a chamber 36 that tapers downward and that is provided with an array of exit holes 35.
Such array of exit holes 35 has a plurality of rows of holes 37, 38, 39 and 40.
The liquid descends from such array of exit holes 35 with a laminar
flow, which produces the liquid curtain 19 indicated with dotted lines in Figures 1 and 2.
Such liquid curtain 19 comprises as many closely- spaced films of liquid as there are rows of holes in the array of exit holes 35, for example four.
The liquid curtain 19 acts as a liquid barrier, with no splashes or turbulence, that affects the front opening 16 across its whole width and for its whole height, and is adapted to slow the bullets before they reach the inside of the deflection chamber 11 , and at the same time cool them.
The fall of the liquid from the second manifold 27 also has the effect of maintaining that liquid at ambient temperature.
The rear tubular body 20, with a vertical axis, for the dissipation of the kinetic and thermal energy of the bullets, is constituted by an external pipe 41 inside which there are multiple vertical redirection walls 42, 43, 44, 45, 46 and 47, which are arranged so as to divert the bullet that enters through the slot 17 toward one of the subsequent walls so that the bullet travels along a spiral trajectory, thus dissipating its kinetic energy and falling downward into the central region 48 of the tubular body 20 proper.
Such vertical redirection walls 42, 43, 44, 45, 46 and 47 are made of ballistic steel.
The tubular body 20 is inundated by the collection and cooling liquid in the compartment defined by the vertical redirection walls, by way of an upper conical diffuser 50 which is clearly visible in Figure 4, supported by a lid 53.
In this case too, the liquid is pumped by the pump assembly 22 and reaches the upper conical diffuser 50 by way of a corresponding pipe 51.
The liquid introduced through the upper diffuser 50 cools the redirection walls 42, 43, 44, 45, 46 and 47, slows the bullets and cools them, and cooperates to entrain downward any fragments and dust into which a bullet may have disintegrated.
Below the tubular body 20 there is a funnel-shaped bottom 52 by way of which the bullets, any fragments and residual dust descend into the underlying means of automatic recovery of the bullets 21.
The funnel-shaped bottom 52 is also provided with a lower conical diffuser 54 which is adapted to both diffuse the descending liquid into the automatic recovery means 21 , and at the same time to protect the underlying recovery means 21 from any bullets that are still ricocheting and whose kinetic energy is not yet exhausted.
In the present, non-limiting embodiment of the invention, such means 21 of automatic recovery of the bullets from the collection and cooling liquid comprise a centrifugal separator 55 and a collection container 56.
Such centrifugal separator 55 is fixed below the funnel-shaped bottom 52 and is connected thereto.
The funnel-shaped bottom 51 introduces collected liquid and bullets into a rotating perforated basket 57, which is rotated by corresponding motorized means, for example an electric motor 58, for example by way of a belt transmission 59.
The rotating basket 57 is contained in a liquid collection chamber 60, with a liquid discharge outlet 61 on the bottom.
The rotation of the perforated basket 57 causes the exit of the collected bullets, which are heavier than the liquid, from the upper opening 62 of the rotating basket 57, from which the bullets fall onto an annular chute 63 and from there into an exit duct 64.
By way of the exit duct 64, the collected bullets are introduced into the collection container 56.
The collection container 56 is constituted by a hermetically- sealed container, made of plastic material or made of metallic material.
The liquid 24 used in such a bullet trap is constituted for example by a non-flammable liquid substance, non-toxic on contact, inhalation and ingestion; such liquid is preferably odorless and colorless.
As previously mentioned, the function of such liquid is to slow and cool the bullets, without evaporating, and to maintain the walls, both of the deflection chamber 11 and of the tubular body 20, at ambient temperature, and also to retain any hazardous dust created with the impacts of the bullets.
The liquid curtain 19 further prevents any vapors, fragments and dust from exiting the deflection chamber 11 through the front.
The collection tub 23 is contoured and dimensioned so as to collect the liquid that descends from the walls of the deflection chamber 11 , the liquid that descends from the liquid curtain 19 and the liquid that descends from the centrifugal separator 55.
The collection tub 23 is provided, in the fall zone of the liquid curtain 19, with a splash guard 70, which is constituted by a metallic grille covered in an upper region by a mat made of micro-perforated plastic material, which is adapted to eliminate splashes and turbulence in the liquid 24 created by the flows descending from the liquid curtain 19 and from the deflection chamber 11.
In practice it has been found that the invention fully achieves the intended aim and objects.
In particular, with the invention a bullet trap has been devised by virtue of which the shattering of the bullet and the release of lead dust are greatly reduced, if not eliminated, by virtue of the cooling and collecting effect produced by the liquid on the bullets, the deflection chamber and the vertical redirection walls.
Furthermore, with the invention a bullet trap has been devised that does not require costs for the separation of materials in order to recover the lead of the bullets, by virtue of the means of automatic recovery of the bullets.
In addition to this, with the invention a bullet trap has been devised that makes it possible to recover the bullets in a substantially integral state, since the cooling to which the bullets are subjected decreases the risk of
sublimation or disintegration.
Moreover, with the invention a bullet trap has been devised by virtue of which the separation of the bullets collected does not require any special labor, it being carried out automatically by the centrifugal separator, which is motorized.
The invention, thus conceived, is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims. Moreover, all the details may be substituted by other, technically equivalent elements.
In practice the components and the materials employed, provided they are compatible with the specific use, and the contingent dimensions and shapes, may be any according to requirements and to the state of the art.
The disclosures in Italian Patent Application No. 102016000097550 (UA2016A006929) from which this application claims priority are incorporated herein by reference.
Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
