Description

TECHNICAL FIELD

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

[0002] The target shooting discipline is clay pigeon shooting. In this field, target launching devices, also known as clay pigeons, are used. Clay pigeon shooting involves launching a pigeon using a mechanical launcher, which a shooter attempts to hit by firing pellets from a shotgun. The pellets then dislodge the target if it is hit. These targets are generally dome-shaped, for example, approximately 110 mm in diameter; the convex shape of the dome forms one face, while the internal volume of the dome forms a second face, opposite the first.

[0003] They are generally made of a material that can withstand the forces of the launcher but also allows them to dislocate when they hit the target with 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 feature four distinct concentric zones. The skirt is located at the periphery, surmounted by the track, which is connected to the dome itself. The dome contains a pellet, typically in the shape of a flat disc, at its center. The skirt and track are subject to a strict design that limits any modification, as these parts are involved in the target's projection. The pellet, however, can be struck by a pellet without causing the target to disintegrate.

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

[0007] Currently, there are two forms for the dome. The first form is represented in Figure 2AIt has a smooth shape. This shape has the advantage of being simple to manufacture; however, its resistance to the impact forces of pellets is significant. This smooth dome shape means that the target does not necessarily shatter upon impact with a pellet.

[0008] The second dome shape currently being developed is shown in Figure 2B and presents 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 areas of strong stress on the edges of the steps.

[0010] However, the compromise between target resistance during launch and low mechanical resistance to disintegration upon impact with the pellet is not optimal, especially over long distances. Some targets with this geometry, launched at distances exceeding 50 meters, will not disintegrate. Indeed, at this distance, the pellets propelled by the firearm will disperse and lose their kinetic energy (illustrated in Figure 1 Furthermore, increasing the distance limits the density of the shot pattern and therefore the number of impacts. Thus, many of the pellets that do hit the target will not break it but will ricochet off it.

[0011] The second form may additionally present cavities as illustrated in patent publication FR1341223 A1. These, however, do not allow for dislocation of the target.

[0012] One object of the present invention is to propose a target architecture featuring stress concentration zones, particularly to improve energy transfer efficiency upon pellet impact at long range and thus increase the target's vulnerability. The other objects, features, and advantages of the present invention will become apparent from the following description and 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, generally in the form of a dome exhibiting axial symmetry about an axis z and comprising a first convex face including from its periphery, a skirt then a tread then a dome having an envelope which includes at least one annular stage centered on the axis z, each annular stage including a step and a riser.

[0014] The target is configured so that for at least one annular stage, the riser comprises a plurality of cavities and so that each cavity has a prism shape having two lateral walls connected to a transverse wall extending from a bottom wall along the z-axis and is according to claim 1.

[0015] Thus, the invention proposes a solution that is particularly resistant to projection and aerodynamic. This solution allows for a target that is both resistant to the forces exerted during its launch by a target-launching machine and vulnerable to breakage from a point force applied by the impact of a pellet fired from a rifle at a great distance. This vulnerability is induced by the cavities, which are favorable locations for the pellet impact to effectively affect the target's breaking strength: firstly, the pellets are trapped within these cavities, and secondly, the cavities weaken the target due to the stress concentrations they produce.

[0016] While current techniques encourage professionals to optimize target materials for improved dislocation, this design proposes a unique architecture that increases the impact zone, thereby enhancing energy transfer and mitigating ricochets by trapping pellets within the target. This solution, in turn, concentrates stresses that promote target fracture through cracking.

[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, features and advantages of the invention will become clearer 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 following 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 as examples and are not limiting to the invention. They constitute schematic representations of principle intended to facilitate understanding of the invention and are not necessarily to scale with practical applications. DETAILED DESCRIPTION

[0020] Before proceeding with a detailed review of embodiments of the invention, optional features that may be used in combination or alternatively are stated below: According to one embodiment, the transverse wall extends from the bottom wall to a height of approximately 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 pellet commonly used in the discipline. Therefore, if the pellet impacts the transverse wall of a cavity tangentially, it will impact its upper edge. Since edges are areas of high stress, the target will disintegrate upon impact of the pellet 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] According to one example, the at least one annular stage comprises 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 cavities from one annular level to another in a checkerboard pattern allows it to act as a shot trap regardless of the target's orientation 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] According to 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 front edge of cavity bottom wall, a top edge of cavity transverse wall, two lateral edges of side walls, and also has a rear edge of cavity bottom, two lateral edges of cavity bottom, two transverse wall edges formed by the preferably orthogonal intersection of the side walls, the transverse wall and the bottom wall.

[0029] The edges preferentially have angles between two walls of around 90°. This geometry creates stress concentration zones that promote cracking of the target upon impact on these edges.

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

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

[0032] According to an 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 therefore 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 edges of the side walls are configured so as to form a slope with an angle between 20° and 40°, preferably between 24° and 34°.

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

[0036] The slope allows us to respect the curvature of the target and 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 an 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 lateral walls of the cavities provides better reception of the 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 detailed description that follows, terms such as "horizontal," "vertical," "longitudinal," "transverse," "superior," "inferior," "high," "low," "front," "rear," "inside," and "outside" may be used. These terms should be interpreted relatively in relation to the normal position of a target, cavities on that target, or the normal position of an element having a convex dome shape.

[0043] In the following description, the term "on" does not necessarily mean "directly on." Thus, when it is stated that a part or component A rests "on" a part or component B, this does not mean that parts or components A and B are necessarily in direct contact with each other. These parts or components A and B may be either in direct contact or supported by one or more other parts. The same applies to other expressions, such as "A acts on B," which can mean "A acts directly on B" or "A acts on B through 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 convex dome shape with two faces. The two faces are configured so as to allow the target 1 to withstand the launching forces of a launching machine but also to be sufficiently fragile to break if struck by a pellet 2 fired from a firearm (illustrated in Figure 2001). 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, circle 1 can comprise four zones exhibiting axial symmetry about an axis z. These four zones will be described from the periphery of target 1 to its center.

[0046] In one embodiment, the target 1 includes 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 area. Overall, the skirt 101 may be in the form of a ring surrounding the rest of the target.

[0047] In one embodiment, the target 1 includes a tread 102. The tread 102 is mounted on top of 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 launching arm of a target launcher 1. It must be sufficiently robust for this function.

[0048] When launched by a target-launching machine 1, target 1 can be subjected to two velocities orthogonal to each other. The first velocity is linear, along the x-axis (perpendicular to z and along a radius of the target), and the second velocity is gyroscopic, along the z-axis. The gyroscopic velocity increases brittleness through the internal stresses it generates and can cause fragility in the skirt 101 and the tread 102. However, this velocity decreases with 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 spray 20 of lead 2, illustrated in Figure 1, depending on its orientation in space during the projection of target 1, by a percentage that 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 pellet 2 from weapon 2001 has a significant percentage of impacting the target at the level of the envelope 110.

[0050] In one embodiment, the envelope 110 may have a specific shape. The shape of the envelope 110 can provide the target 1 with aerodynamic lift during its flight. The shape of the envelope 110, in synergy with the potential percentage of impact on this envelope 110, implies that it is important to consider this envelope in the design of the target 1. In one embodiment, the target 1 includes a disc 103 at the center of the dome 100. The disc 103 is substantially flat and preferably circular. The disc 103 allows the target 1 to have sufficient lift to be projected into the air over distances of at least 50 m.

[0051] The dome's 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. This at least one annular stage exhibits axial symmetry about the z-axis, preferably like the rest of the target. The at least one annular stage 120 a, b, c can be described as a circle with a projected height along the z-axis.

[0053] In one embodiment, the at least one annular floor 120 a, b, c comprises a tread 121a and a riser 121b. As an example, each riser 121b may have a slope. This slope is understood to be a slope that ascends along the z-axis as one moves towards the center of the target 1. Thus, the presence of the tread 121a and the riser 121b increases the potential impact surfaces and creates areas of high stress on the edges formed by the junction of the tread 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 can, in one example, have up to four immediately successive annular floors.

[0056] The succession of annular floors 120a, 120b, 120c increases the impact areas and stress zones as the number of annular floors 120a, b, c increases.

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

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

[0059] According to one embodiment, the cavities 131 of the first annular stage 120a can 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. In 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, thus forming a checkerboard pattern 130. Therefore, in one example, the cavities 131 of an annular stage 120a,b,c can be positioned aligned with the cavities 131 of a non-consecutive annular stage 120a,b,c.

[0060] The staggered distribution in a format similar to a checkerboard 130 of the cavities 131 of one annular floor 120 a, b, c to another annular floor 120 a, b, c allows the lead to be trapped in the cavities 131 and to avoid the ricochet effects observed in the versions of the earlier art.

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

[0062] In one embodiment, the cavities 131 are angularly offset by one cavity width between two annular stages 120a, 120b. This offset of one width optimizes the number of cavities 131 and thus maximizes the amount of impact surface area. In another 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 with 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 dimensions of each cavity 131 are based on studies to ensure that each cavity 131 is large enough to capture a shot size 2, for example, 7 to 8 caliber, preferably 7.5 caliber, at a distance L of more than 50 m. Thus, the shot size 2 can have a diameter between approximately 2.25 mm and 2.5 mm, and preferably a diameter of 2.37 mm. The cavities 131 act as shot size 2 catchers; the cavities 131 can be larger to receive the shot size 2.

[0065] In one embodiment, the cavities 131 preferably have the shape of a right prism with a triangular base. The shape of the cavities 131 thus allows the pellets 2 to be captured regardless of the orientation of the target 1, thereby limiting the effects of ricochet. Each cavity 131 preferably has four walls. The cavities 131 then comprise, in one example, two lateral walls 1312, 1312' connected to a transverse wall 1313 and a bottom wall 1311.

[0066] According to one embodiment, the transverse wall 1313 extends from the bottom wall 1311 along the z-axis to a height d3 of less than 1.5 mm, preferably less than or equal to 1.1 mm. The transverse wall 1313 thus has a height d3 less than the diameter of a pellet 2 commonly used in the discipline. Therefore, if the pellet 2 impacts the transverse wall 1313 of a cavity 131 tangentially, it will impact a superior edge 1314. Since edges are areas of high stress, the target 1 will disintegrate upon impact of the pellet 2 on this edge 1314.

[0067] According to one embodiment, the orthogonal intersection, for example, of the side walls 1312, 1312', the transverse wall 1313, and the bottom wall 1311 forms edges 1311a, 1311b, 1311c, 1311c', 1312a, 1312a', 1313a, 1313a'. Similarly, the angles between two walls 1311, 1312, 1312', 1313 are approximately 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 areas of stress concentration which promote cracking of target 1 when impacted on these edges.

[0068] According to one embodiment, the bottom wall 1311 includes a rear edge 1311b, due to its junction with the transverse wall 1313. The bottom wall 1311 also includes a front edge 1311a corresponding to its junction with the step 121a. The front edge 1311a of the bottom wall 1311 may, in 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 front edge 1311a compared to the rear edge 1311b is intrinsic to the fact that the cavities 131 are located on an annular floor 120 a, b, c. Preferably, the widths d1 and d2 of cavity 131 must be sufficient to allow a lead 2 to be captured by cavity 131. In one embodiment, the width d1 may 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 cavity 131 can therefore be large enough for a lead 2 to be captured by cavity 131.

[0069] According to one embodiment, the width d2 can thus be less than or equal to 2.7 mm, preferably less than or equal to 2.6 mm. The transverse wall 1313 can therefore be slightly larger than the diameter of a pellet 2. Thus, in the event of an impact, the pellet 2 can strike the transverse wall 1313 tangentially and cause the target 1 to break. According to one embodiment, the bottom wall 1311 also includes 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' can, depending on the embodiment, be concave or straight; 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 present a slope with an angle θ2 between 20° and 40°, preferably 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, as an example, the slope formed by the lateral edges 1312a, 1312a' on the first annular stage 120a could be greater, for example by 34°, than the slope on the third annular stage 120c, which could be, for example, 24°. The slope formed by the lateral edges 1312a, 1312a' allows the curvature of target 1 to be maintained and thus not impact the aerodynamics of target 1.

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

[0072] According to one embodiment, the transverse wall 1313 of each cavity 1313 also includes 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 lateral walls 1312 and 1312' of a cavity 131 have a rounded shape. The rounded shape of the lateral walls 1312 and 1312' allows a cavity 131 to have a larger impact surface. Indeed, compared to a smooth shell 110, the presence of the rounded cavities 131 increases the impact surface by approximately 16%. Thus, the pellets 2 can impact an edge with a greater probability and promote better energy transfer, thereby limiting the ricochet effect by "trapping" the pellets in the target. The lateral walls 1312 and 1312' are, for example, concave with respect 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 follows from the previous description that the presence of the transverse wall 1313 and the lateral walls 1312, 1312' allows both to create a receiving area for the lead 2 while creating strong stress areas 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 area compared to the first embodiment. However, this embodiment provides an interesting alternative; indeed, despite the reduction in the impact area of ​​the pellets, it has been observed that the sharp, straight edges compensate for this reduction.

[0078] Target 1 can thus be used in a 2000 system with a 2001 firearm loaded with pellets 2 from a cartridge. For target 1 to effectively trap the pellets, the pellets 2 used should preferably be caliber 7, 7.5, or 8, or any size between 7 and 8. DIGITAL REFERENCES
