Description

"Targets for shooting" TECHNICAL AREA 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 The shooting discipline is clay pigeon shooting. In this field, we know of target launching 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. They are generally made of a material capable of resisting the forces of the launcher but also allowing dislocation when the target is hit by a projectile such as a pellet from a firearm. Currently, in order for the targets to have sufficient resistance to throwing but break when hit by a pellet, the first convex face has at least, from an external crown to a central circular portion, a step and a riser, each riser having a slope. The second face is smooth. However, the resistance of the targets to the launchers while keeping a minimum thickness for a dislocation during the impact with the lead is not optimal. Some targets can break when thrown by the thrower and others may not disintegrate visibly or at least not spectacularly. An object of the present invention is therefore to propose a target architecture having stress concentration zones thus promoting the rupture of the target while maintaining resistance to throws. 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 To achieve this objective, according to one embodiment, a target for clay pigeon shooting is provided, comprising a body in the general shape of a dome comprising a first convex face and a second concave face opposite the first face, the body comprising an outer crown connecting the first face to the second face, and in which the second face comprises at least one central circular portion having an axis of axial symmetry z. The target is configured such that the second face of the body comprises an alternation of trenches and ribs each extending radially from the outer crown to the circular portion. In addition, it comprises, for each trench, for at least one portion at the bottom of the trench up to the first face, a body thickness less than or equal to 2 mm, preferably less than or equal to 1.5 mm. Thus, the invention proposes a particularly resistant and aerodynamic solution. 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 a fragility necessary for rupture during a point force applied with the impact of a pellet fired by a rifle. While current techniques guide those in the trade towards optimizing the materials used to manufacture targets for better dislocation, a particular architecture is proposed here allowing increased resistance to throwing while maintaining optimal breakability for shooting. As a result, the proposed solution allows for a distribution of constraints favorable to throwing by a mechanical throwing arm while allowing for an increase in target breakage during lead impacts. BRIEF DESCRIPTION OF THE FIGURES The aims, objects, as well as the features and advantages of the invention will become more apparent from the detailed description of one embodiment thereof which is illustrated by the following accompanying drawings in which: Figure 1 shows a profile view of a target. Figure 2 shows the second face of a target. Figures 3A to 3B show the second face of a target and a cross section at the trenches. Figures 4A to 4B show the second face of a target and a cross section at the ribs. Figure 5 shows a section of a trench. The drawings are given as examples 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 Before beginning 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 trenches and the ribs have an obtuse junction angle less than or equal to 110°, preferably less than or equal to 108°. This strong variation in angle provides a concentration of stress, thus avoiding stiffening the target in certain directions, in particular by avoiding triangulating the structure. According to one example, the thickness of the body at the at least one rib portion up to the first face
