Description

TECHNICAL FIELD

[0001] This presentation concerns the field of target shooting and securing environments in which projectiles travel and are stopped. More specifically, it concerns a device for braking and recovering projectiles propelled by weapons towards targets, as well as a target system incorporating such a device. STATE OF THE ART

[0002] The practice of shooting with firearms, whether handguns or shoulder-fired, using compressed air, gas, or powder as propellant, is a widespread activity. This practice is generally carried out at shooting ranges, either outdoors (or "outdoor" according to Anglo-Saxon terminology), as in sport shooting disciplines or in the discipline of biathlon, or indoors (or "indoor" according to Anglo-Saxon terminology), in which the objective is to hit one or more targets successively with a projectile propelled by the firearm.

[0003] For obvious safety and space reasons, it is necessary to stop the projectile once it has reached the intended target. However, projectiles can have energies ranging from a few joules to several thousand joules. But since targets are generally consumables, they present very little resistance to the projectile and therefore do not allow for the desired stopping function.

[0004] It is possible to place mounds or piles of sand or earth behind each target to stop the projectile after it passes through. However, these mounds are bulky, difficult to set up in some shooting ranges, and not very adaptable. Furthermore, they do not allow for easy retrieval of the projectiles once they have been stopped, as they are buried in the mound, which is problematic in terms of pollution and recycling.

[0005] It is also possible to set up cages, called bullet traps, directly behind each target. These bullet traps present a sufficiently strong obstacle to stop the projectile. They use a fixed wall, often metallic, to impede the projectile's trajectory.

[0006] In biathlon, the projectile passes through an opening in a first steel target plate and strikes a steel paddle, usually black, positioned behind the opening in the first plate. The impact of the projectile on the paddle slows its trajectory and, more importantly, causes the paddle to tilt, confirming that the shot has indeed passed through the opening in the first target plate.

[0007] However, such bullet traps or pallets can cause projectiles to ricochet in dangerous directions, such as towards the shooter, which poses a safety risk. Furthermore, stopping a projectile, for example against a wall, plate, or pallet, causes it to crush and release dust. Projectiles commonly used are made of metallic materials, such as lead, whose dust is harmful to health and the environment. It is common for a projectile to lose a portion, on the order of 2 to 3% of its mass, when stopped by such means. This explains why air pollution at shooting ranges can, in some cases, exceed the permitted threshold of 100 µg / m³, and why surface pollution can reach values ​​several hundred times higher than the permitted threshold of 1,000 µg / m².These bullet traps therefore present significant safety and pollution problems by dispersing lead dust into the air of the shooting range. Furthermore, for biathlon, current targets introduce inaccuracies if the projectile makes contact with the edge of the opening in the steel target plate, and require manual adjustment of the opening size depending on whether the shooting position is standing or prone.

[0008] Document FR 2865534 proposes the use of a system comprising vertical fabric tubes positioned within a housing that supports a target. These tubes are fixed to the upper wall of the housing and are intended to slow down projectiles fired toward the targets. However, the concentration of shots at the center of the target causes significant wear on the central tubes and greatly reduces the lifespan of such a system. Therefore, this system cannot reliably slow down or retrieve a large number of successive projectiles without requiring maintenance or replacement of some tubes.

[0009] Relevant additional prior art EP3444559B1, DE4436060A1, DE10221527A1, US5577734A, DE858951C.

[0010] It would therefore be advantageous to address all or part of the problems outlined above. GENERAL STATEMENT

[0011] One aim of the presentation is to solve at least one of the problems mentioned above, by enabling, for example, the improvement of the reliability of firing results and the recovery of moving projectiles while reducing the release of polluting particles and the risk of the projectile bouncing back in a simple and efficient way over time.

[0012] To this end, according to one aspect of this presentation, a projectile braking and recovery device is proposed, comprising: a support from which several brake tubes or strips are suspended, the brake tubes or strips being suspended by one of their ends on the support; a motor driving the support in rotation around an axis of rotation; the brake tubes or strips hanging from the support, by gravity so as to absorb the energy of a projectile impacting a brake tube or strip.

[0013] This system improves projectile braking by placing a greater number of tubes along the trajectories most frequently followed by projectiles, namely those passing through the center of the target. The number of tubes used is thus reduced by minimizing the number of tubes along the less frequent projectile trajectories, i.e., those to the sides relative to the firing axis.

[0014] Furthermore, it distributes wear across all the tubes, despite the higher concentration of shots passing through the center of the device, by rotating them so that the same tube is not always positioned behind the center of the target. This increases the device's lifespan before the first maintenance.

[0015] Advantageously, but optionally, the device in question includes at least one of the following features, taken alone or in any combination: the brake tubes or strips are arranged on the support according to several annular alignments around the axis of rotation; the support is a plate whose axis of rotation is parallel to the brake tubes (3), the brake tubes being suspended by one end on an underside face of the support and the alignments being concentric; the brake tubes adjacent to the same alignment as well as the brake tubes adjacent to adjacent alignments are spaced apart by a distance greater than 1 mm and less than the diameter of the brake tubes; each straight line passing through the center of rotation of the plate intercepts at least one of the brake tubes of at least one of the alignments; the support is a shaft, parallel to the axis of rotation and perpendicular to the brake strips hanging from the support, each alignment of brake strips being arranged around the support and the alignments being juxtaposed along the axis of rotation of the support;The support comprises, for each brake tube or strip: a hole in which the brake tube or strip can slide freely, and a shoulder for fixing the brake tube or strip to the support, the shoulder being wider than the hole in the support into which the brake tube or strip fits; the device comprises a housing defining a cavity within which the support and the brake tubes or strips are positioned, the housing comprising a lateral opening parallel to the axis of rotation of the support for the entry of projectiles into the device; the device comprises a braking plate for slowing a projectile, the braking plate being positioned parallel to the axis of rotation and perpendicular to a projectile trajectory and being configured to slow a projectile before the projectile impacts a brake tube or strip; the braking plate is made of polyurethane;The motor is positioned on a top cover of the housing and outside the cavity, the motor being connected to the disc by means of a connecting screw fixed to the disc on one side and to the motor on the other, and passing through the top cover; the disc is supported by the top cover by means of: the connecting screw and a pin, blocking the connecting screw in translation relative to the top cover of the housing, and a needle bearing, on which the pin rests, allowing the connecting screw to rotate relative to the cover.

[0016] According to another aspect, a targeting system is proposed comprising a device as previously described and an electronic target, the electronic target being positioned in front of the device so that a projectile passing through the target is then slowed down and recovered by the device;

[0017] Advantageously, the targeting system can include: a display device for the effectiveness and / or success of a shot; the display device controlled by an electrical signal emitted by the target according to a trajectory of a projectile in the target and a target parameter.

[0019] Across all figures, similar elements bear identical references. DETAILED DESCRIPTION OF IMPLEMENTATION METHODS

[0020] In the following description, a radial direction will be defined as that which is directed by a vector collinear with a radius, and an axial direction as that which is directed by a vector collinear with an axis of rotation. Furthermore, since the device of the invention is intended to be positioned relative to the ground, the lower part will be defined as the portion of a component closer to the ground in the direction of gravity compared to a portion, referred to as the upper part, which is further from the ground in the direction of gravity.

[0021] A targeting system 100 may include one or more target(s) 200 and a projectile braking and recovery device 1 P.

[0022] The target 200 supports one or more visual elements serving as a reference point for the shooter, allowing them to aim and the device 1 The braking and recovery system allows the projectile to be stopped downstream of the target 200 P shot by the shooter.

[0023] The device 1 braking and recovery includes a support 2, to which are suspended several tubes or braking strips 3, and an engine 4 leading to the support 2 rotating around an axis of rotation X. By rotating the support 2, the engine 4 allows one to avoid being exposed to projectiles P always the same tubes or brake strips 3. Indeed, various projectiles P successive wheels can thus be slowed down by encountering different tubes or braking strips. 3. Wear on brake tubes or strips 3 is thus distributed across each of the brake tubes or strips 3.

[0024] Brake tubes or strips 3 hanging from the support 2, by gravity and are suspended by one of their ends 3b on the support 2. Brake tubes or strips3 are configured to absorb the energy of a projectile P impacting them.

[0025] The entire set of brake tubes or strips 3 is arranged in relation to the support 2 according to several subsets, the subsets are called alignments 5. In each alignment 5 brake tubes or strips 3 are arranged at regular intervals around the axis of rotation X. The alignments 5 can be arranged radially or axially relative to each other, with respect to the axis of rotation X, on the support 2. Each alignment 5 can be annular in order to present a uniform obstacle to the projectile despite the rotation of the support 2. Low-energy projectile braking and recovery device

[0026] According to one embodiment, the support 2 is a plate on which the brake tubes are suspended 3. The motor drives the plate 2 rotating on itself around the axis of rotation X, the axis of rotation X being parallel to the tubes 2 (in other words, vertical, or parallel to the direction of gravity).

[0027] The plaque 2, as illustrated by the Figures 2A and 2B , includes a so-called lower face 2a, a so-called upper surface 2b and a slice 2c. Plate 2 further includes a centroid O and an axis orthogonal to the lower faces 2a and superior 2b and passing through the center of gravity O Subsequently, and due to the geometry of the plate 2, we will assimilate the plate to a single plane. The plate 2 includes a maximum length and a minimum length in the plane orthogonal to the axis. The shape of the plate 2is such that the difference between the dimensions of the maximum length and the minimum length is small compared to the dimension of the maximum length. In this way, the evolution of the length of the projection of the slice 2c, on a fixed plane orthogonal to the plate 2, during the rotation of the plate 2 around its axis, is small compared to the maximum length of the plate 2. Thus, the surface area presented by the tubes 3 suspended from the plate 2 The rotational speed is relatively constant over time. Advantageously, the plate 2 forms a regular polygon or preferably a circle. According to a preferred embodiment, the plate 2 is a disc.

[0028] The tubes 3, as illustrated by the figure 3 include an upper end 3b and a lower end 3a. Their upper end 3bis attached to the underside 2a of the plate 2 and their lower end 3a is free to move. The plate 2 includes for each tube 3 a hole 2d in which the tube 3 can slide freely. Each tube 3 includes a shoulder 31 attached or integrated into the tube. The shoulder 31 includes a head 311 wider than the hole 2d of plate 2. Each shoulder 31 therefore allows a tube to be fixed 3 on the plate 2. Such a fixing makes replacement easier of a single tube 3 and to simplify the attachment of each tube 3 on the plate 2..

[0029] The tubes 3 are suspended from the plate 2due to gravity, they are all parallel to each other. This allows them a pendulum-like motion so that they can absorb the energy of projectiles. P by their deformation and by their movement.

[0030] The tubes 3 They are preferably cylindrical in shape and circular in cross-section, so as not to present any angular parts to the projectiles. P. In this way, when the projectile P comes into contact with a tube 3, This cylindrical shape promotes the lateral repulsion effect of the tube 3 and thus reduces the risk of it being severed.

[0031] According to one embodiment, the tubes 3 They are hollow, which improves the absorption of the projectile's energy. P through the tube 3.

[0032] The tubes 3 are made of a flexible material, so that they can absorb the energy of projectiles.P. The tubes 3 They can be made of fossil-based, recycled, or bio-based polymer materials such as elastomer, polyurethane elastomer, polyvinyl chloride, thermoplastic, synthetic rubber, or other similar materials. The tubes 3 They can also be made of flexible materials of natural origin, such as natural rubber, leather, or other similar materials. Thus, the tubes 3 absorb the projectile's energy P by deforming and swaying, which prevents the projectile from deforming. P himself.

[0033] Advantageously, and as illustrated by the figure 2A the tubes 3 can be arranged on the underside 2a of the plate 2 according to one or more alignments 5 centered at the center O of the plate 2. The different alignments5 tubes 3 are therefore concentric. We will subsequently call this a cylinder C tubes 3 the volume defined by all these alignments 5 tubes 3 and axis of rotation X the axis parallel to tubes 3 and passing through the center of gravity O of the plate 2. We will also call it the firing axis Y, an axis perpendicular to the axis of rotation X. Preferably, the different tubes 3 of each alignment 5 are not all positioned on the same radii; in other words, each straight line passing through the center of gravity of plate 2 intersects at least one of the tubes 3 of at least one of the alignments 5 tubes 3 fixed to the underside of the plate 2. According to one embodiment, the tubes 3 alignments 5neighbors are arranged in a staggered pattern, so that the trajectory of a projectile P cannot intersect two alignments 5 successive without encountering at least one tube 3.

[0034] Advantageously, the tubes 3 are spaced apart from each other, that is to say between two tubes 3 neighbor in the same alignment 5 and between tubes 3 neighbors of two alignments 5 neighbors, at a distance d on the order of half a tube diameter 3.

[0035] The diameter of a tube 3 optionally, it can be chosen based on the diameter of the projectiles. P to stop, in which case the diameter of tubes 3 will advantageously be on the order of one and a half times that of the projectiles P.

[0036] This sizing allows the device 1 to be able to slow the projectile down Pgradually using several tubes 3 each of which will capture a portion of the projectile's energy. Indeed, each tube 3 is thick enough to offer some resistance to the projectile P, without breaking, and sufficiently spaced from the tubes 3 neighbors so they can move around and leave the projectile P impact other tubes 3. Furthermore, such an arrangement allows for the display of a greater number of tubes 3 to the projectiles P passing through the center of the device 1 and therefore the cylinder C depending on its diameter while allowing for rotation. The device is ideally suited for slowing down projectiles. P propelled by means of a weapon using compressed air energy. The device is therefore advantageously used for projectiles P exhibiting an energy of a few joules to a few tens of joules.

[0037] The engine 4 is connected to the upper surface 2b of the plate 2. The engine 4 allows the plate to be driven 2 rotating around the axis of rotation X passing through its center of gravity O. The motor 4 is connected to the plate 2 by means of a connecting screw 10. The connecting screw 10 is preferentially collinear with the X axis of rotation. The connecting screw 10 is attached to the upper surface 2b of the plate 2 on the one hand and to an output tree 4a of the engine 4 On the other hand. The connection between the connecting screw 10 and the plate 2 is a fixed link that allows the connecting screw 10 to rotate the plate 2, It can be of several types, such as a bolted connection.

[0038] The engine 4It can be of any type, such as an AC or DC motor, or a stepper motor, etc...

[0039] The engine 4 rotates at a speed between half a revolution per minute (0.5 revolutions per minute) and five revolutions per minute (5 rpm) so as to prevent two projectiles P successive impacts on the same tube 3. Thus, the projectiles P do not always encounter the same tubes 3 due to the rotation of the plate 2 and the uncertainty of the point of impact due to the accuracy of the shooter.

[0040] According to a first embodiment, the axis of rotation X of the plate 2 is collinear with the axis of revolution of the plate 2. According to a second embodiment, the rotation axis X of the plate 2 is inclined angularly with respect to the axis of revolution of the plate 2.This second embodiment also allows for the distribution of any potential impacts over a larger portion of the height of each tube. 3. Indeed, due to the angular inclination, the projectile P could impact a tube at the beginning of the race 3 on its lower part, and at the end of its travel, the last tube 3 on its upper part.

[0041] Thus, such a device 1 braking and projectile recovery P allows a projectile to be slowed down P propelled in its direction while avoiding being crushed by the projectile P. In addition, it guarantees a good lifespan for the tubes 3 due to the rotation of the plate 2 through which two projectiles P Shots fired along the same trajectory but with a time lag will not impact the same tubes 3.

[0042] Advantageously, the device 1braking and projectile recovery P may include a case 6. The case 6 includes a side wall 14, a lid 8 upper and lower face 15. The case 6 therefore defines a cavity 7 inside which the plate 2 and the tubes 3 are positioned. The cavity defined by the casing is large enough to contain plate 2, the volume of cylinder C, and the projectiles fired and fallen to the bottom of the casing 6. However, a drawer can be added to the lower part of the case. 6 in order to be able to regularly evacuate the projectiles P pulled and retrieved. According to the embodiment illustrated by the figure 1 the axis of rotation X of the tube 3 passes through the center of the top lid 8 and the underside 15.

[0043] The side panel of the case 6 includes a side opening 9 Coaxial with a paper or electronic target placed in front of it. The lateral opening 9 It has a width and a height. The width of the cavity 7 is of a dimension less than or equal to the diameters of the alignments 5 concentric tubes 3 and the height of the cavity 7 is of a dimension smaller than the length of the tubes 3. The cavity 7 is preferably centered on the X axis of rotation of the cylinder C. In this way, the device 1 allows a projectile P projected along the Y-axis of fire towards the target to enter the cavity 7 of the device 1 and to encounter at least one tube 3. Such an arrangement also allows for the matching of, on the one hand, the density of the number of tubes 3and on the other hand, the concentration of the projectiles P. Indeed, since a shooter's objective is to hit the center of the target, projectiles more often pass through its center than its periphery. However, the center of the cavity 7 being facing the axis of the cylinder C, a projectile P passing through the cavity 7 at its center crosses diametrically the cylinder C tubes 3 and therefore meets the number of tubes 3 as much as possible.

[0044] Furthermore, the cavity 7 is advantageously positioned halfway up the tubes 3 in order to protect the plate 2 potential projectile impacts P while opposing the projectiles P the most important moment possible by leaving the largest possible portion of the tube 3 free below the point of impact. The casing 6This allows for good positioning of the target relative to the cylinder C and therefore to guarantee that the projectiles P impacting the center of the target, they pass through the cylinder C diametrically and in its center.

[0045] Preferably, and as illustrated by the figure 3 , the lid 8 can support the engine 4 and the disc 2, regardless of the engine 4. In other words, the weight of the disc 2 and the cylinder C, so tubes 3, can be supported by the lid 8 of the case 6 and not by the engine 4 itself, that is to say through its output tree 4a, via the connecting screw 10. According to one embodiment, the connecting screw 10, attached to the plate 2, through the lid 8and includes in a portion above the cover 8 a radial drilling 16 opening into which a pin 11 is inserted. Such an assembly allows the plate to be locked in translation. 2 in the direction of gravity. To facilitate the rotation of the connecting screw 10 in relation to the lid 8, it is possible to put it in place around the connecting screw 10 and between the pin 11 and the lid 8 a needle stop 12. The pin 11 therefore rests on the needle bearing 12 which itself rests on the lid 8. Thus, the plate 2 is supported by the lid 8 and is free to rotate relative to the lid 8.

[0046] The lid 8 of the case 6 allows the engine to be supported 4. The engine 4 can be fixed to a part 18 in shape of omega, itself screwed onto the lid 8, as illustrated by the figure 4 . Thus the engine 4 is positioned above the connecting screw 10. The connecting screw 10 connecting the plate 2 to the engine 4 through the lid 8, is supported in translation by the lid 8 and is attached to the output shaft 4a of the engine 4. Advantageously, the connecting screw 10 and the output tree 4a of the engine 4 are fixed to each other by means of an intermediate piece 17.

[0047] According to one embodiment, the intermediate piece 17 is pinned onto the output shaft 4a of the engine 4 and has a tenon at one end. The connecting screw 10 has a mortise so that it can be fixed to the intermediate piece 17 by a mortise and tenon joint.

[0048] According to another embodiment, the intermediate piece 17 includes a jaw coupling, the upper half of which is fixed to the output shaft 4a of the engine 4 and a lower half on the connecting screw 10.

[0049] Advantageously, the case 6 may include a drawer 13. The drawer 13 is positioned in a lower part of the cavity 7, under the tubes 3, to receive the projectiles P once their energy has been released.

[0050] In this way, the projectile P entering the cavity 7 gives its energy to the tubes 3, is slowed down upon contact with them, then falls to the bottom of the casing 6 and is thus recoverable without having encountered the side wall 14 of the case 6 and therefore did not crash.

[0051] According to a particular embodiment, the casing 6 is a rectangular parallelepiped whose width and length (in a plane parallel to the ground) are between 50 and 500 mm, and preferably between 200 and 250 mm, and whose height is between 50 and 600 mm, and preferably between 300 and 400 mm. The lateral opening 9 of the case 6 has a width and height between 20 and 400mm and preferably between 150 and 200mm.

[0052] According to a particular embodiment, the casing 6 is a rectangular parallelepiped with a width and length of 210mm and a height of 360mm. The side opening 9 of the case 6 It has a width and a height of 175mm.

[0053] According to a particular embodiment, which may or may not be combined with the previous one, the diameter of the disc constituting the plate 2is between 100 and 250 mm and preferably between 190 and 195 mm and the height of the tubes 3 is between 200 and 300 mm and preferably 280 mm

[0054] The case 6 can include from 10 to 300 tubes 3 with a diameter between 2 and 20mm and spaced 0.5 to 5mm apart.

[0055] Thus, this device 1 The braking and recovery system helps reduce pollution in a firing environment caused by the dispersion of lead particles in the air when a projectile stops. This device is configured to progressively brake projectiles with energies ranging from a few joules to several thousand joules, and preferably a few tens of joules, which is considered low energy. Medium-energy projectile braking and recovery device

[0056] In some embodiments, the device 1Braking and recovery may include a brake plate 20, as illustrated for example by the figure 5A The brake plate 20 is configured to slow the projectile down P before the projectile P does not encounter the braking lines 3. The brake plate 20 is positioned on the trajectory of the projectile P, between the target 200 and the braking strips 3.

[0057] The presence of the brake pad 20 This improves braking performance and thus reduces wear on the brake pads. 3. A device 1 braking and recovery with a braking plate 20 This allows you to slow down and recover projectiles. P whose energy is greater than a device 1 braking and recovery without a brake plate 20,without damaging the projectiles or therefore generating pollution upon impact.

[0058] The brake plate 20 is made of polymer of a thickness and hardness chosen according to the energy to be absorbed. The braking plate 20 It can be made of urethane or polyurethane polymer, which closes on itself after the projectile passes through (in other words, the plate is self-healing). The braking plate 20 is configured to be impacted by projectiles P whose energy can range from a few tens of joules to a few hundred joules and more particularly up to 150 joules.

[0059] Advantageously, the brake plate 20 can comprise two parts: a central part 21 and part of the outline 22, as illustrated for example by the figure 5B The central part 21can be removable and thus easily replaced in the contour part 22. Indeed, the central part 21 being in the middle of the brake pad 20 It is more often struck by a projectile. P that the edges of the contour part 22 (since a shooter's objective is to hit the center of the target) and is therefore worn out more quickly. The central part 21 may include a shoulder 21a and / or grooves to prevent any potential rebound or backward movement, and to maintain the central part 21 in the outline 22 when the central part 21 is struck by a projectile P.

[0060] Thus, a device 1 braking and recovery according to the first embodiment combined with the braking plate 20This device helps reduce pollution in a shooting environment caused by the dispersion of lead particles in the air when a projectile stops. 1 is configured to gradually slow down projectiles whose energy can be between a few joules and a few thousand joules and preferably a few hundred joules, which is considered an average energy. High-energy projectile braking and recovery device

[0061] According to a second embodiment, illustrated for example by the Figures 6A and 6B the device 1 The braking and recovery system differs from the first embodiment in that the support 2 is a tree extending around the axis of rotation X, and in that it includes braking strips 3 which hang by gravity from the shaft 2 perpendicular to the axis of rotation X.In this embodiment, the tree extends in a horizontal direction, that is, perpendicular to the direction of gravity. Tree 2 can be a bar or a hollow cylinder.

[0062] The alignments 5 braking strips 3 are juxtaposed along the X axis of rotation of the shaft 2. Each alignment 5 consists of braking strips 3 arranged around the circumference of the tree 2. The braking strips 3 adjacent to two alignments 5 adjacent are in contact, or spaced less than 3mm apart.

[0063] During firing, motor 4 drives shaft 2 in rotation around the X-axis, so that each braking strip 3 of each alignment 5 it winds and then unwinds around the tree 2, due to the rotation of the X-axis. The braking strips 3 of the different alignments5 thus form a curtain parallel to the axis of rotation X. The progressive winding of the brake strips 3 on the tree 2, and therefore their relative translation in the vertical plane, allows the braking strips 3 to avoid being impacted in the same place by a projectile aimed at the same fixed target. This also prevents the projectile from always presenting the same braking surface. 3, of each alignment 5, as the first obstacle, but to present them one after the other. This increases the lifespan of the tapes and extends their longevity.

[0064] The engine 4 is a low-speed geared motor with a rotational speed between 0.05 and 0.2 rpm, and preferably 0.1 rpm. The shaft 2 and the engine 4 are supported by a metal structure 23.

[0065] The rotation speed of bar 2 and therefore the winding speed of the brake bands 3 around the bar 2 This can be a function of a predetermined firing rate by the shooters. Thus, a rotation speed of the bar of approximately 0.1 to 0.2 revolutions per minute induces a displacement of the braking bands. 3 In the vertical direction, the environment moves at 25 cm per minute, for a bar with a diameter between 170 and 400 mm. Such a movement affects braking surfaces. 3 contributes to improving the longevity of brake pads 3. Indeed, a first projectile P can impact a first braking strip 3 in the first part of the strap, near the brake band attachment 3 to bar 2. And a second projectile P following the first projectile P by a time interval during which the bar rotates and wraps around the first braking strip 3,may impact the first braking band 3 in a section of the braking zone 3 different from the first part, and further from the attachment of the brake band 3 to the bar 2 than the first part due to the winding of the brake band 3 around bar 2.

[0066] Furthermore, a projectile that would become stuck in one of the braking zones 3, can be detached thanks to the relative sliding movement between a braking strip 3 and a braking strip 3 neighbor induced by the winding / unwinding around the bar 2.

[0067] Advantageously, the metal structure 23 can support a tree 2 of great length, such as a length corresponding to several firing positions, for example 5 times 0.75 m for 5 shooting ranges. But it can also support only one tree2 whose length corresponds to a single firing position, i.e., 0.75. In this latter case, several sets of firing positions can be linked together to form sets of 1, 2, 3, 4, or 5 firing positions. Whether it is a structure with 1 or more firing positions, the shaft is always rotated by the motor. 4.

[0068] Whether it's a single-position or multi-position firing system, the entire assembly can be moved in translation (for example, using feet with lockable casters) relative to one or more targets. 200. This allows for adaptation to the needs of a shooting range, but also for the ability to distribute wear evenly across all braking surfaces. 3. It is therefore sufficient to translate the braking and recovery device 1 along the axis of rotation X.

[0069] Each braking strip 3It can be a strip with a width between 10mm and 300mm, but preferably 100mm, and a thickness between 1mm and 10mm, preferably 8mm. The width and thickness of the braking band 3 are chosen based on the energy of the projectiles P to absorb. The braking strips 3 They can be made of polymer, and more specifically PVC. Preferably, the brake strips 3 can be made of so-called crystal PVC and have a hardness between 30 and 80 shore A, preferably between 50 and 70 shore A.

[0070] To prevent a projectile P does not pass between the braking lines 3 of two alignments 5 neighbors without being slowed down, each braking lane 3 of the same alignment 5 can be offset by half a width from each of the braking strips 3 neighbor in alignment5 considered. It is also possible to foresee that the braking strips 3 of two alignments 5 adjacent ones should be arranged in a staggered pattern.

[0071] The number of braking strips 3 by alignment 5 is a function of the desired thickness to absorb the energy of projectiles. In other words, the number of braking strips 3 by alignment 5 is a function of the energy of the projectiles to be slowed down. The number of braking strips 3 by alignment 5 can be between 5 and 30 braking strips 3. Preferably, for braking projectiles with energy on the order of a thousand joules, the number of braking strips 3 by alignment 5 can be 18 and for braking projectiles with energy on the order of a hundred joules, the number of braking strips 3 by alignment 5can be between 5 and 12.

[0072] Thus, a device 1 The braking and recovery system according to the second embodiment reduces pollution in a firing environment caused by the dispersion of lead particles in the air when a projectile stops. Indeed, depending on the number of braking strips 3, this device 1 is configured to gradually slow down projectiles whose energy can range from a few joules to a few hundred joules, or even a few thousand joules, which is considered high energy.

[0073] Furthermore, the rotation of the brake bands 3 helps improve the lifespan of brake pads 3, as explained previously, and therefore to guarantee good braking of projectiles for longer without requiring the braking strips to be changed 3.

[0074] The braking plate described above can also be used with this second embodiment of the braking device. Target

[0075] The target 200 of the targeting system 100 can be electronic, as illustrated for example by the figure 7 This improves the accuracy of shot readings and also prevents contact with the target. 200 and the projectile P which can release lead particles, as for example in the case of targets used in biathlon, known as tilting targets.

[0076] The projectile P can thus pass through the target 200, the accuracy of the shot being measured electronically, and then entering the device 1 braking and recovery to be recovered.

[0077] The target 200 may include a sighting zone 210 and a display area 220.

[0078] The target area 210 (or target visual) may include one or more frame(s) 211 each comprising a detection device 212 and a targeting device 213. Each frame 211 is configured to be traversed by a projectile P and is associated with a device 1 braking and recovery system into which the projectile emerges after passing through frame 211. The aiming device 210 is configured to give shooters indications of the area to hit within the frame 211 with the projectile P. The detection device 212 is configured to detect the passage of a projectile P within the frame 211 and the position of the projectile P in order to determine if the projectile P reached the target area. The detection device 212 may include one or more sensor(s) 214such as infrared, laser or optical sensors.

[0079] The display area 220 is configured to indicate to the shooter if the projectile P reached the target area of ​​the frame 211 considered. The display area 220 can therefore include, for each frame 211 of the target area 210, an indicator of success 221, like a color palette, for example white, activated according to an electronic signal from the detection device 212. The display area 220 can also include, for each frame 211 of the target area 210, a firing indicator 222 to inform a spectator whether the shot was taken or not.

[0080] The target 200 Electronics allows the function of a mechanical target to be fulfilled without inducing contact with the projectile. P. A projectile Pfired in the direction of a target 200 therefore crosses the frame 211 of the target area 210, his crossing of the frame 211 is detected by the detection device 212, and the projectile P then enters the device 1 braking and recovery.

[0081] Thus, the target 200 electronics allows with the device 1 braking and recovery systems facilitate projectile firing P towards a predetermined target area, to improve the accuracy of the reading and to slow down and recover the projectile without crushing the projectile against a wall.
