Description

TECHNICAL FIELD

[0001] The present invention relates to the field of targets, in particular for practicing shooting with firearms. The various disciplines of clay pigeon shooting are particularly targeted. STATE OF THE ART

[0002] The shooting discipline is clay pigeon shooting. In this field, we know target throwing devices also called clay pigeons. Clay pigeon shooting consists of throwing a pigeon by a mechanical launcher that a shooter tries to reach by firing pellets using a rifle. The pellets then dislocate the target if it is reached. These targets are generally dome-shaped targets, for example about 110 mm in diameter; the convex shape produced by the dome creates a first face while the interior volume of the dome creates a second face, opposite the first.

[0003] They are generally made of a material capable of resisting the forces of the launcher but also allowing dislocation when the target is reached by a projectile such as a pellet from a firearm.

[0004] Currently, in order for targets to have sufficient resistance to throwing but break upon impact with a pellet, the first convex face can have different geometries.

[0005] The targets all have four distinct concentric zones. The skirt is located at the periphery, it is surmounted by the tread, which is connected to the dome itself containing in its center a pellet typically in the form of a flat disc. The skirt and the tread are subject to a strict design limiting any modification because these parts are involved in the projection phases of the target. The pellet itself can be impacted by a pellet without causing dislocation of the target.

[0006] Thus, there remains mainly only the part of the dome that can influence the breakability of a target.

[0007] Currently, there are two shapes for the dome. The first shape is shown in Figure 2A, it has a smooth shape. This shape has the advantage of being simple to make, however the resistance to impact forces from pellets is significant. This smooth shape of the dome means that the target does not necessarily disintegrate when a pellet hits it.

[0008] The second dome shape currently realized is shown in Figure 2B and has at least one annular floor which includes at least one step and one riser, each riser having a slope.

[0009] This dome geometry has the advantage of increasing the possible impact surfaces and creating high stress zones on the edges of the steps.

[0010] However, the compromise to be found, between the resistance of the targets during launch while maintaining a low mechanical resistance for dislocation upon impact with the pellet, is not optimal, especially over long distances. Some targets with this geometry, launched at distances of more than 50m, will not dislocate. Indeed, at this distance, the pellets projected by the firearm will disperse and lose their kinetic energy (illustrated in Figure 1 ). In addition, increasing the distance limits the density of the pellet spray and therefore the number of impacts. Thus, many pellets that will still impact the target will not break it but will ricochet off it.

[0011] The second form may additionally have cavities as illustrated in patent publication FR1341223 A1. However, these do not allow dislocation of the target.

[0012] An object of the present invention is therefore to propose a target architecture having stress concentration zones in particular to improve the efficiency of energy transfer upon impact of pellets at long distance and therefore increase the vulnerability of the target. The other objects, characteristics and advantages of the present invention will appear on examining the following description and the accompanying drawings. It is understood that other advantages may be incorporated. SUMMARY

[0013] To achieve this objective, according to one embodiment, a target for clay pigeon shooting is provided, in the general shape of a dome having axial symmetry along a z axis and comprising a first convex face comprising, from its periphery, a skirt then a tread then a dome having an envelope which comprises at least one annular stage centered on the z axis, each annular stage comprising a step and a riser.

[0014] The target is configured such that for at least one annular stage, the riser comprises a plurality of cavities and such that each cavity has a prism shape having two side walls connected to a transverse wall extending from a bottom wall along the z axis.

[0015] Thus, the invention proposes a solution that is particularly resistant to projection and aerodynamic. This solution makes it possible to have a target that is both resistant to the forces during the projection of the target by a target launching machine and to have the necessary vulnerability to rupture during a point force applied with the impact of a pellet fired by a rifle at a great distance. This vulnerability is induced by the cavities which are a favorable location for the impact of the pellets to effectively affect the resistance to rupture of the target: on the one hand the pellets are trapped there and on the other hand the cavities are areas that weaken the target due to the stress concentrations that they produce.

[0016] While current techniques direct professionals towards optimizing the materials used to manufacture targets for better dislocation, a particular architecture is proposed here that allows an increase in the impact zone, promoting better energy transfer and limiting the ricochet effect by "trapping" the pellets in the target. As a result, the proposed solution allows for a concentration of stresses that promote fracture by cracking of the target.

[0017] A second aspect concerns a system comprising the target, a cartridge loaded with pellets, and a firearm configured to fire pellets from the cartridge at the target, the pellets having a caliber between 7 and 8, preferably having a caliber of 7.5. Therefore, the solution has cavities sized to obtain optimal breakability for the pellets most used in the discipline. BRIEF DESCRIPTION OF THE FIGURES

[0018] The aims, objects, as well as the characteristics and advantages of the invention will emerge more clearly from the detailed description of an embodiment thereof which is illustrated by the following accompanying drawings in which: There Figure 1 represents a view of a system of the present invention. The Figures 2A And 2B show target geometries according to the prior art. The Figure 3 shows a view of the target according to the invention. The Figures 4A to 4B show two embodiments of the cavities present on the target according to the invention.

[0019] The drawings are given by way of example and are not limiting of the invention. They constitute schematic representations of principle intended to facilitate the understanding of the invention and are not necessarily to the scale of practical applications. DETAILED DESCRIPTION

[0020] Before commencing a detailed review of embodiments of the invention, optional features which may optionally be used in combination or alternatively are set out below: According to one embodiment, the transverse wall extends from the bottom wall substantially over a height less than 1.5 mm, preferably less than or equal to 1.1 mm along the z axis. The transverse wall thus has a height less than the diameter of a lead usually used in the discipline. Thus, if the lead impacts the transverse wall of a cavity tangentially, it will impact its upper edge. Since the edges are high stress zones, the target will dislocate upon impact of the lead on this edge.

[0021] In one example, the cavities are distributed periodically around the circumference of the riser.

[0022] The periodic distribution of cavities allows for a uniform distribution of impact surfaces and stresses.

[0023] In one example, the at least one annular stage includes a first annular stage and a second annular stage each having a plurality of cavities, the cavities of the first annular stage being angularly offset from the cavities of the second annular stage.

[0024] The staggered distribution of the cavities from one annular level to another in a checkerboard format allows it to act as a lead trap regardless of the orientation of the target and thus limits the ricochet effect.

[0025] According to one example, the cavities of the first annular stage and the second annular stage have the same width dimension.

[0026] In one example, the cavities of the first annular stage are angularly offset by half a cavity width relative to the cavities of the second annular stage.

[0027] According to one example, the first annular stage and the second annular stage are immediately successive.

[0028] According to one example, each cavity has a cavity bottom wall front edge, a cavity transverse wall top edge, two side wall lateral edges, and also has a cavity bottom rear edge, two cavity bottom lateral edges, two transverse wall edges formed by the preferably orthogonal intersection of the side walls, the transverse wall and the bottom wall.

[0029] The edges preferably have angles between two walls of the order of 90°. This geometry makes it possible to create stress concentration zones promoting fracture by cracking of the target during an impact on these edges.

[0030] In one example, the cavity bottom front edge has a width greater than a cavity bottom rear edge width.

[0031] The difference in width between the front and back of the cavity allows for better capture of pellets in the cavity and thus avoids ricochet effects.

[0032] According to one example, the width d1 is less than or equal to 4 mm, preferably less than or equal to 3.9 mm.

[0033] The width d1 is thus greater than 1.5 times the diameter of a lead, thus ensuring the capture of a lead in the cavity.

[0034] According to one example, the two side wall edges are configured to form a slope with an angle between 20° and 40°, preferably between 24° and 34°.

[0035] In one example, the slope varies depending on the annular stage along the z axis.

[0036] The slope allows the curvature of the target to be respected and does not impact its aerodynamics.

[0037] In one example, the side walls have a rounded shape that is concave relative to the center of the cavity.

[0038] According to one example, the concave rounded shape of the side walls has a concavity within a radius R2 between 1.7 mm and 2.2 mm, preferably the concavity has a radius R2 of 2 mm.

[0039] The concavity of the side walls of the cavities provides better reception of pellets and better propagation of forces upon impact.

[0040] According to one example, the cavities follow the circumference of the target at an angle preferably less than or equal to 60°.

[0041] In one example, the side walls are flat.

[0042] In the following detailed description, use may be made of terms such as "horizontal", "vertical", "longitudinal", "transverse", "upper", "lower", "top", "bottom", "front", "rear", "inner", "outer". These terms must be interpreted relatively in relation to the normal position of a target, cavities on this target or the normal position of an element having a convex dome shape.

[0043] In the remainder of the description, the term "on" does not necessarily mean "directly on". Thus, when it is indicated that a part or member A is supported "on" a part or member B, this does not mean that the parts or members A and B are necessarily in direct contact with each other. These parts or members A and B may be either in direct contact or be supported on each other by means of one or more other parts. The same applies to other expressions such as, for example, the expression "A acts on B", which may mean "A acts directly on B" or "A acts on B by means of one or more other parts".

[0044] The present invention relates to a target 1 used for clay pigeon shooting. The target 1 has a general shape of a convex dome having two faces. The two faces are configured so as to allow the target 1 to resist the throwing forces of a throwing machine but also to be sufficiently fragile to break if a pellet 2 fired from a firearm 2001 (illustrated in Figure 1 ) impacts target 1. Target 1 then has a precise geometry on its first face 10 to increase the vulnerability of target 1 when it is hit by a pellet 2. Generally, the first face 10 is directed upwards in its flight when it is projected by a machine.

[0045] According to one embodiment, the circle 1 may comprise four zones having axial symmetry along a z axis. These four zones will be described from the periphery of the target 1 to its center.

[0046] According to one embodiment, the target 1 comprises a skirt 101. The skirt 101 is subject to a strict design prohibiting any modification. The skirt 101 is preferably dimensioned to withstand frictional forces during the transport of the target 1 to the launch zone. Overall, the skirt 101 may have the shape of a ring surrounding the remainder of the target.

[0047] According to one embodiment, the target 1 comprises a tread 102. The tread 102 surmounts the skirt 101. Like the skirt 101, the tread is subject to a strict design prohibiting any modification. The tread 102 may correspond to the area in contact with the throwing arm of a target launcher 1. It must be strong enough for this function.

[0048] When projected by a target throwing machine 1, the target 1 may be subjected to two speeds orthogonal to each other. The first speed is linear, along the x axis (perpendicular to z and along a radius of the target), the second speed is gyroscopic, along the z axis. The gyroscopic speed makes it possible to increase breakability by internal tensions that it generates and can cause fragility to the skirt 101 and the tread 102. However, this speed decreases with the distance L (illustrated in Figure 1 ) and can thus limit the vulnerability of the skirt 101 and the tread 102 for distances L greater than 40 m, preferably for distances L greater than 50 m.

[0049] According to one embodiment, the target 1 comprises a dome 100. The dome 100 has a surface, or envelope 110. This envelope 110 can be exposed to a shower 20 of lead 2, illustrated in Figure 1, depending on its orientation in space when projecting the target 1 according to a percentage which can be between 20% and 60%, preferably between 28% and 53%. This percentage corresponds to the percentage of the dome surface 100 relative to the total surface of the first face 10. Thus the lead 2 coming from the weapon 2001 has a significant percentage of impacting the target at the level of the envelope 110.

[0050] According to one embodiment, the envelope 110 may have a specific shape. The shape of the envelope 110 may provide the target 1 with aerodynamic lift during its flight. The shape of the envelope 110 in synergy with the possible percentage of impact on this envelope 110 implies that it is important to take this envelope into account in the design of the target 1. According to one embodiment, the target 1 comprises a pellet 103 at the center of the dome 100. The pellet 103 is substantially planar and preferably circular in shape. The pellet 103 allows the target 1 to have sufficient lift to be projected into the air over distances at least greater than 50 m.

[0051] The dome envelope will now be described according to the Figure 3 .

[0052] According to one embodiment, the envelope 110 of the dome 100 comprises at least one annular stage 120 a, b, c. The at least one annular stage has axial symmetry along the z axis, as, preferably, the rest of the target. The at least one annular stage 120 a, b, c can be described as a circle having a projected height along the z axis.

[0053] According to one embodiment, the at least one annular stage 120 a, b, c comprises a step 121a and a riser 121b. According to one example, each riser 121b may have a slope. This slope is understood to be a slope which rises along the z axis as one moves towards the center of the target 1. Thus, the presence of the step 121a and the riser 121b makes it possible to increase the possible impact surfaces and to create high stress zones on the edges formed by the junction of the step 121a with the riser 121b.

[0054] According to one embodiment, the at least one annular stage 120 a, b, c comprises at least a first annular stage 120a and a second annular stage 120b. The first annular stage 120a and the second annular stage 120b being positioned immediately successively.

[0055] According to one embodiment, the envelope 110 may, according to one example, have up to four immediately successive annular stages.

[0056] The succession of annular stages 120a, 120b, 120c makes it possible to increase the impact surfaces and the stress zones by the more annular stages 120a, b, c there are.

[0057] According to one embodiment, each annular stage 120 a, b, c comprises a plurality of cavities 131. According to one example, the plurality of cavities 131 is positioned on the riser 121b. The cavities 131 make it possible to increase the impact surface of the pellets 2 on the casing 110. Compared to a smooth casing 110 of the prior art illustrated in Figure 2A , the presence of the cavities 131 can increase the impact surface by approximately 16%.

[0058] According to one embodiment, the cavities 131 are, according to one example, distributed periodically around the circumference of the riser 121b. Similarly, the cavities 131 can be positioned at equal distances from each other on the annular stage 120a, b, c. Thus, the periodicity of the position of the cavities 131 allows a uniform distribution of the impact surfaces and stresses.

[0059] According to one embodiment, the cavities 131 of the first annular stage 120a may be positioned with an angular offset relative to the cavities 131 of the second annular stage 120b. Similarly, the cavities of the third annular stage 120c are positioned with an angular offset relative to the cavities 131 of the second annular stage 120b. According to one example, the cavities 131 are positioned in a staggered pattern from one annular stage 120a, b, c to another annular stage 120a, b, c, making it possible to form a checkerboard 130. Therefore, according to one example, the cavities 131 of an annular stage 120a, b, c may be positioned aligned with the cavities 131 of a non-successive annular stage 120a, b, c.

[0060] The staggered distribution in the format similar to a checkerboard 130 of the cavities 131 from one annular stage 120 a, b, c to another annular stage 120 a, b, c makes it possible to trap the pellets in the cavities 131 and to avoid the ricochet effects observed in the versions of the prior art.

[0061] According to one embodiment, the cavities 131 may have the same width d1 (illustrated in Figure 4A ) from one annular stage 120 a, b, c to another annular stage 120 a, b, c.

[0062] According to one embodiment, the cavities 131 are angularly offset by a cavity width between two annular stages 120a, 120b. The offset by a width makes it possible to optimize the number of cavities 131 and thus maximize the quantity of impact surfaces. According to one embodiment, the cavities 131 positioned on an annular stage 120a, b, c, preferably follow the circumference of the target 1. Preferably the cavities 131 have an opening having an angle θ1 preferably less than or equal to 60°.

[0063] The cavities 131 will now be described according to the Figures 4A And 4B .

[0064] The sizing of each cavity 131 is the result of a study so that each cavity 131 can be of sufficient size to capture a pellet 2 coming from a caliber for example 7 to 8, preferably coming from a caliber 7.5 at a distance L preferably of more than 50 m. Thus the pellets 2 can have a diameter of substantially between 2.25 mm and 2.5 mm and can preferably have a diameter of 2.37 mm. The cavities 131 act as pellet sensors 2, the cavities 131 can have larger dimensions to receive the pellets 2.

[0065] According to one embodiment, the cavities 131 preferably have the shape of a right prism with a triangular base. The shape of the cavities 131 thus makes it possible to capture the pellets 2 regardless of the orientation of the target 1 and thus limit the ricochet effects. Each cavity 131 preferably has four walls. The cavities 131 then comprise, according to one example, two side walls 1312, 1312' connected to a transverse wall 1313 and to a bottom wall 1311.

[0066] According to one embodiment, the transverse wall 1313 extends from the bottom wall 1311 along the z axis substantially over a height d3 less than 1.5 mm, preferably less than or equal to 1.1 mm. The transverse wall 1313 has a height d3 thus less than the diameter of a lead 2 usually used in the discipline. Thus, if the lead 2 impacts the transverse wall 1313 of a cavity 131 tangentially, it will impact an upper edge 1314. The edges being areas of high stress, the target 1 will dislocate upon impact of the lead 2 on this edge 1314.

[0067] According to one embodiment, the intersection, according to one example, orthogonal of the side walls 1312, 1312', of the transverse wall 1313 and of the bottom wall 1311 forms edges 1311a, 1311b, 1311c, 1311c', 1312a, 1312a', 1313a, 1313a'. In a similar manner, the angles between two walls 1311, 1312, 1312', 1313 have an angle substantially equal to 90°. The junction between the walls can therefore be abrupt, so the edges 1311a, 1311b, 1311c, 1311c', 1312a, 1312a', 1313a, 1313a', 1314 form stress concentration zones promoting fracture by cracking of the target 1 during an impact on these edges.

[0068] According to one embodiment, the bottom wall 1311 comprises a rear edge 1311b, due to its junction with the transverse wall 1313. The bottom wall 1311 also comprises a front edge 1311a corresponding to its junction with the step 121a. The front edge 1311a of the bottom wall 1311 may, according to one example, have a width d1 greater than a width d2 of the rear edge 1311b of the bottom wall 1311 of each cavity 131. A greater width at the level of the front edge 1311a relative to the rear edge 1311b is intrinsic to the fact that the cavities 131 are located on an annular stage 120 a, b, c. However, it is preferable that the widths d1 and d2 of cavity 131 are sufficient for a lead 2 to be captured by cavity 131. According to one embodiment, the width d1 may thus be less than or equal to 4 mm, preferably less than or equal to 3.9 mm. The width d1 is thus greater than 1.5 times the diameter of a lead 2.The opening of the cavity 131 can thus be large enough for a lead 2 to be captured by the cavity 131.

[0069] According to one embodiment, the width d2 may thus be less than or equal to 2.7 mm, preferably less than or equal to 2.6 mm. The transverse wall 1313 may thus have a size slightly larger than the diameter of a pellet 2. Thus, in the event of an impact, the pellet 2 may impact the transverse wall 1313 tangentially and cause the target 1 to break. According to one embodiment, the bottom wall 1311 also comprises two lateral edges 1311c, 1311c' of the bottom wall 1311 of the cavity 131, due to its junction with the lateral walls 1312, 1312'. The edges 1311c and 1311c' may, depending on the embodiment, be concave or rectilinear; these embodiments will be detailed below.

[0070] According to one embodiment, each cavity 131 comprises two lateral edges 1312a, 1312a' of lateral walls 1312, 1312'. The two lateral edges 1312a, 1312a' are substantially positioned so as to have a slope with an angle θ2 of between 20° and 40°, preferably of between 24° and 34° with respectively the two lateral edges 1311c, 1311c' of bottom wall 1311 of cavity 131. The shape of the dome can induce different angles θ2 depending on the vertical position of the cavities (131). Thus, according to one example, the slope produced by the lateral edges 1312a, 1312a' on the first annular stage 120a may be greater, for example 34° than the slope on the third annular stage 120c, which may be for example 24°. The slope produced by the lateral edges 1312a, 1312a' makes it possible to maintain the curvature of the target 1 and thus not impact the aerodynamics of the target 1.

[0071] According to one embodiment, the lateral edges 1312a, 1312a' of the lateral walls 1312, 1312' connect, according to one example by their ends, the front edge 1311a of the bottom wall 1311 and the upper edge 1314 of the transverse wall 1313.

[0072] According to one embodiment, the transverse wall 1313 of each cavity 1313 also comprises two longitudinal edges 1313a, 1313a' which extend substantially along the z axis over a height d3, with a height d3 preferably less than or equal to 1.1 mm.

[0073] The cavities 131 will now be described according to a first embodiment of the invention illustrated in Figure 4A .

[0074] According to this first embodiment, the side walls 1312 and 1312' of a cavity 131 have a rounded shape. The rounded shape of the side walls 1312, 1312' allows a cavity 131 to have a larger impact surface. Indeed, compared to a smooth casing 110, the presence of the rounded cavities 131 increases the impact surface by approximately 16%. Thus, the pellets 2 can impact an edge with greater probability and promote better energy transfer, making it possible to limit the ricochet effect by "trapping" the pellets in the target. The side walls 1312, 1312' are, for example, concave relative to the center of the cavity 131 with a radius R2. The radius R2 of a rounded cavity 131 is preferably between 1.7 mm and 2.2 mm, preferably the concavity has a radius R2 of 2 mm.

[0075] It thus follows from the preceding description that the presence of the transverse wall 1313 and the side walls 1312, 1312' makes it possible to create a zone for receiving the pellets 2 while creating strong stress zones at the level of each of the edges 1313a, 1313a', 1312a, 1312a', 1311c, 1311c', 1314, 1311b, 1311a.

[0076] The cavities 131 will now be described according to a second embodiment of the invention illustrated in Figure 4B .

[0077] According to this second embodiment, the side walls 1312 and 1312' are flat. The flat side walls 1312 and 1312' have the disadvantage of reducing the impact surface compared to the first embodiment. However, this embodiment forms an interesting alternative; in fact, despite the reduction in the impact surface of the pellets, it has been found that the sharp and straight edges make it possible to compensate for this reduction.

[0078] Target 1 can thus be used in a 2000 system with a 2001 firearm loaded with 2 pellets from a cartridge. In order for target 1 to effectively trap pellets, the 2 pellets to be used may preferably be 7, 7.5 or 8 gauge pellets, or any value between 7 and 8 gauges. DIGITAL REFERENCES
