[0001] Base for target launching machine
[0002] TECHNICAL FIELD
[0003] The present invention relates to the field of target throwing machines. It finds particularly advantageous application in the shooting sports industry, and in particular clay pigeon shooting.
[0004] STATE OF THE ART
[0005] In the target shooting industry, and particularly in the clay pigeon shooting world, customers are keen on a wide variety of shots. This requires machine manufacturers to allow for a wider range of possible target trajectories.
[0006] Many existing target launching machines have mobilities allowing the angles at which the targets are fired to vary. Thus, the machine presented in patent publication FR 3066813 A1 discloses a target launching machine equipped with a base allowing two mobilities at 90° to each other, by means of arc-shaped slides.
[0007] An object of the present invention is therefore to provide a machine base, and a launching machine system equipped with such a base, providing improved mobility of the machine relative to the base.
[0008] 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.
[0009] SUMMARY
[0010] To achieve this objective, according to one embodiment, a base for a target launching machine is provided, comprising: • a lower part;
[0011] • an upper portion configured to carry a target launching machine, the upper portion being mounted with mobility relative to the lower portion;
[0012] • an actuator configured to control the mobility of the upper part relative to the lower part.
[0013] Advantageously, the basis is such that:
[0014] • the lower part includes an external arch;
[0015] • the upper part includes an inner arch nested in the outer arch;
[0016] • mobility includes a rotation of the inner arch into the outer arch along a swing axis.
[0017] Thus, the base has a double arch configuration allowing an optimized movement of the upper part relative to the lower part. In one aspect, the optimization is aimed at obtaining a greater angular amplitude, in particular to obtain extreme trajectories for the targets. In another aspect, alternative or cumulative, the optimization is related to a better distribution of the loads applied to the inner arch, in particular to limit the forces that the actuator must apply.
[0018] For example, it is possible to increase the success rate of shooters to attract a wider clientele than experienced shooters. Standard targets are in fact discoidal in shape and have a domed cap and except in trajectories flying over the shooter, the orientation of the target in flight only exposes its lateral profile to interfere with the pellet spray, which adds a certain complexity to the shots. A greater angular travel of the machine, made possible here, therefore makes it possible to increase the surface area that the pellets can reach.
[0019] The arch shape also provides significant rigidity in a preferred direction by limiting the overall volume of the part equipped with this arch, whether lower or upper.
[0020] Furthermore, it allows the inner arch to be nested in the outer arch, preferably forming a relatively homothetic superposition of the two arches, without substantially increasing the height of the base. Overall, the lower part of the inner arch, and preferably a majority of the height of the inner arch, is integrated into the interior volume of the latter, when the inner arch is in the same plane as the outer arch. This shape is also favorable to the greatest possible movement of the inner arch during its rotation.
[0021] Another aspect relates to a target launching system comprising a target launching machine and a base as shown herein, the target launching machine being carried by the base.
[0022] Considering the significant weight of the machine, its mounting on such a base advantageously allows for optimized positioning to limit the influence of the displacement of the center of gravity of the mobile assembly when the machine is inclined. BRIEF DESCRIPTION OF THE FIGURES

[0047] • the secondary axis 44 is perpendicular to the swing axis 34 and / or in which the secondary axis 44 and the swing axis 34 are concurrent;
[0048] • the base 4 comprises a plurality of anchoring points 47, preferably four anchoring points uniformly distributed at 90° around the secondary axis 44, each configured to interchangeably mount one end of the secondary actuator 45;
[0049] • the secondary axis 44 is located in the plane of symmetry;
[0050] • the primary axis 14 is located in the plane of symmetry;
[0051] • the upper part comprises a counterweight 37, preferably removably mounted.
[0052] • the target launching machine 5 comprises a target storage barrel 52, and the system comprises a maximum load configuration in which the barrel 52 is fully filled with targets 6, and a minimum load configuration in which the barrel 52 is completely empty of targets 6;
[0053] • an assembly formed by the target launching machine 35 and the upper part has a first center of gravity in the maximum load configuration and a second center of gravity in the minimum load configuration, the assembly having an extreme position in which the outer arch 1 and the inner arch 3 have a maximum relative angle, the swing axis 34 being located so that a torque value exerted by the weight of the assembly, in the direction of the swing axis 34, in the maximum load configuration is substantially equal to a torque value exerted by the weight of the assembly in the minimum load configuration in the extreme position;
[0054] • the orthogonal projection of the center of gravity of the assembly on the support plane 21 is located in a central third of the orthogonal projection of the support on the support plane 21.
[0055] It is specified that in the context of the present invention, the expression "substantially equal" means a value which is not more or less than 10% different from another value.
[0056] The arch shape offers a concave geometry. "Imbricated" means that the inner arch is mounted so that it can swing in the concavity of the outer arch. Typically, this imbrication is such that, when the inner arch is in a vertical plane at rest, it extends generally parallel to the outer arch, the profiles of the two arches being superimposed. This does not exclude the inner arch from protruding beyond the outer arch, in particular above the swing axis. In other words, when the two arches are in the same plane and close to each other, the inner arch fits into the concave space defined by the outer arch above it, the concave profiles of the two arches being oriented in the same direction.
[0057] The invention presented here comprises a machine 5 configured to launch targets 6. The latter may be of the clay pigeon type, which have a circular, plate-shaped section and which are generally used for the practice of clay pigeon shooting. This application is not limiting. In particular, targets made of polymer material for the practice of archery on a moving target is another possible application.
[0058] Overall, a machine 5 of common design can be implemented and reported on the basis described in detail in the remainder of the description. Typically, the machine 5 comprises a launching part 51. In the latter, a target ready for launching is generally arranged on a launching plane 511 to be projected by an arm 512 movable in rotation and controlled by a motorized arming and triggering system.
[0059] To allow repeated shooting practice, it is generally known to associate a barrel 52 with the launching part 51. As reflected in Figures 1 and 2, the barrel 52 is arranged above the launching part 51 and it has means for successive delivery of at least one target 6 thus removed, in the direction of the launching plane 511.
[0060] The barrel 52 typically comprises a plurality of columns in each of which the targets 6 can be superimposed. It is thus typically possible to store several dozen targets 6. It is easily understood that the weight of the machine 5 is substantial, especially when many targets are stored. For example, the weight of an empty machine 5 can be 70 kg and the maximum target load 30 kg. The base on which the machine 5 rests must therefore be capable of supporting such a weight, and this in different positions of the machine, to allow different firing directions. In particular, this may include very inclined positions of the machine relative to the base, as can be seen for example in Figures 11 and 12.
[0061] As can be seen in particular in the embodiment of figures 1 and 2, the base presented here comprises from a support plane 21 typically corresponding to the ground, a support 2 carrying an external arch 1. This assembly typically belongs to a lower part of the base. It is surmounted by an internal arch 3 mounted to move relative to the external arch 1. The internal arch 3 itself carries a base 4 at the level of which the machine 5 is received. Typically, the internal arch 3 and the base 4 belong to an upper part of the base which is thus movable relative to the lower part.
[0062] At the very least, there is therefore relative rotational mobility between the arches 1, 3. Figures 1 and 2 show an actuator 35 for controlling this mobility. They also reveal a primary actuator 15 for controlling relative mobility between the support 2 and the outer arch 1, as well as a secondary actuator 45 for controlling relative mobility between the inner arch 3 and the base 4. Although not essential to the implementation of the invention, the primary and secondary actuators and the movements they allow give the base a greater variety of configurations to allow very varied positions of the launching machine 5.
[0063] According to one possibility, at least one of the actuators 15, 35, 45 is a jack, and preferably an electric jack. In particular, at least one of these jacks can be controlled by means of a control interface such as a remote control, and / or by means of a programmable device ensuring random or non-random variations in position.
[0064] With reference to Figure 3, illustrating the isolated base of the machine 5, we can first note an example of the embodiment of the external arch 1. The latter can be produced in the form of a profile, either in a single piece, or from an assembly of a plurality of elementary profiles. In the example shown, the cross-section of the external arch is rectangular, and more precisely square.
[0065] In this example, the outer arch 1 has a first branch 11 forming part of its length, and a second branch 12 forming another part of its length, the two branches being opposite. Still in this example and without limitation, the branches 11, 12 are fixedly connected by a junction block 13 typically located halfway along the length of the outer arch 1. As will be seen later, the block 13 also preferably provides the possibility of making a connection to the support 2.
[0066] For example, the length of the interior arch projected onto the support plane 21 may be greater than or equal to 80 cm and / or less than or equal to 150 cm.
[0067] Preferably, the first branch 11 and the second branch 12 are symmetrical relative to a plane passing through the middle of the length of the outer arch 1 and directed according to the section of the branches. It will be seen that this plane can comprise an axis of rotation 14 of the arch 1 relative to the support 2.
[0068] Preferably, the outer arch 1 also has a symmetry according to a plane 17 illustrated in figure 3 and extending vertically by cutting the arch 1 in the middle of its width.
[0069] Preferably, the branches 11, 12 and the block 13 are made of a material or based on a metallic material, such as steel. The configuration in the form of arched profiles of the branches makes it possible to use hollow elements limiting the weight of the arch 1. At the same time, satisfactory rigidity is provided.
[0070] The outer arch 1 defines, between these two distal ends 111, 121, a concavity oriented upwards forming a clearance space for the upper part, and in particular for the inner arch 3.
[0071] This movement is permitted around a swing axis 34 shown diagrammatically in Figure 4; typically, the axis 34 is horizontal in a normal position of use; at the very least, it is advantageously parallel to the ground, that is to say to the support plane 21. The swing is produced by the articulation of the inner arch 3 relative to the outer arch at the two distal ends of these arches. In particular, one end 311 of the inner arch 3 is connected to one end 111 of the outer arch 1 by a pivot connection which can be materialized by a shaft 341. On the opposite side, another end 321 of the inner arch 3 is connected to another end 121 of the outer arch 1 by another pivot connection which can be materialized by a shaft 342.
[0072] Reference may be made to the description of the outer arch 1 for examples of possible construction details for the inner arch 3; in particular for the choice of materials, the geometry and the construction in the form of profiles. In particular, the arch 3 may comprise a first branch 31 and a second branch 32 fixedly connected by means of a junction block 33 advantageously located in the center of the inner arch 3 and opposite the junction block 13 in the situation of FIG. 3.
[0073] The length, in projection on the plane 21, of the inner arch 3 is less than that of the outer arch 1 so that the branches of the outer arch 1 frame the branches of the inner arch 3. In a height direction, the inner arch 3 extends mainly, or even completely, between these two ends so as to be located in the concavity of the outer arch 1 when it is directed in the plane 17, as is apparent from figure 3. In this situation, the concavity of the inner arch 3 is directed in the same direction as that of the outer arch 1, meaning that the two arches are nested. According to the possibility illustrated in figure 3, it will be noted that a basal part of each of the arches, at the level of the junction blocks, is rectilinear, so that the two arches are parallel at this level in a direction parallel to the axis 34.
[0074] As indicated previously, the rotation around the axis 34 is carried out by an actuator 35. Figures 3 and 4 make it possible to visualize this control by a movement of the rod 352 of this actuator 35 relative to its body 351. In the illustrated case, one end of the actuator 35 is mounted on the outer arch 3, here by means of a mounting part 36 fixed on the arch 3. The opposite end of the actuator is mounted on the inner arch 1, and, in this example, by means of a lever arm 353. While the rod 352 is retracted in the case of Figure 3, it is at least partially deployed in the case of Figure 4 so as to induce a rotation of the inner arch 3 following the movement of the arrow in Figure 4.
[0075] This arrangement allows a degree of freedom between the lower part and the upper part of the base, to vary the inclination of the machine in the direction 34. For example, Figure 11 and Figure 12 give two examples of the result produced by this inclination, examples in which arch 3 has a non-zero angle relative to arch 1. The inclination that can be reproduced is not limited, but can very well cover a movement of up to 80° around the vertical position shown in Figure 3.
[0076] To drive the machine 5 in this inclination, the base comprises a base 4 carried by the inner arch 3. As shown in FIG. 4 in particular, the base 4 may have a plate 41 supported by the junction block 33 as well as an upright 42 projecting from the upper surface of the plate 41, the machine being advantageously fixed to the upright 42, in particular by screwing. Preferably, a pivot 43 makes it possible to adjust the inclination between the upright 42 and the plate 41, thus providing additional adjustment capacity for the orientation of the machine 5.
[0077] Preferably, the base 4 is mounted in rotation on the inner arch 3, around an axis 44 visible in Figure 5. This rotation is also controlled by the actuator 45. One end of the actuator 45 is mounted on the inner arch 3, as is the case for the body 451 of the actuator 45 in the figures, while the other end of the actuator 45 is mounted on the base 4, as is the case for the rod 452 in the figures. It is understood that a translational movement of the rod 452 makes it possible to modify the angular position of the base 4 relative to the inner arch 3. This is revealed by the variations in position as visible in particular in Figures 4, 5 and 6 and the arrows illustrating the rotation in Figures 5 and 6.
[0078] According to an advantageous option, the actuator 45 can be mounted on the base 4 at different locations on the plate 41 corresponding to the anchoring point 47 referenced in FIGS. 5 and 6. For example, by simple screwing and unscrewing operations, it is possible to modify the angular sector of rotational movement of the base 4 relative to the inner arch 3, for a limited actuator 45 stroke. For example, if the stroke is configured to be able to produce a 90° movement, the positioning of four anchoring points 47 spaced 90° apart on the plate 41 allows a 360° movement capacity of the base 4 relative to the inner arch 3.
[0079] To guide this rotation, a pivot is preferably positioned in the center of the plate 41 opposite the junction block 33.
[0080] Figure 7 shows an example of orientation of a machine 5 thanks to the base of the invention. The arrow visible there shows in particular that it is possible to project a target 6 by the arm 512 in a very downwardly inclined manner, the launching plate 511 being very inclined in this case. With the same inclination of the inner arch 3, Figure 8 shows a very different orientation of the firing direction by an arrow directed strongly upwards, the base 4 having been rotated by the actuator 45 relative to the position of Figure 7. Still by way of example, Figure 9 shows by an arrow another firing direction with another orientation of the base 4 produced by the actuator 45 possibly with the use of a modification of the anchoring point of the latter.
[0081] Figure 10 shows a diagram of another optional movement capability, between the support 2 and the outer arch 1. As mentioned previously, rotational mobility is advantageously permitted between these two parts around an axis 14. For this purpose, a pivot connection is organized between the support and the junction block 13 and the actuator 15 ensures the control of the rotation. As previously, a first end of the actuator 15, here that of the body 151 of the actuator 15, is mounted on the outer arch 1, here by means of a mounting part 16 while the other end, here that of the rod 152, is mounted on the support 2. The movement produced is illustrated by the arrow in Figure 10.
[0082] For example, an angular movement of approximately 90° can be allowed.
[0083] In the case of the different figures, the support 2 comprises a plurality of feet 23 extending from a central zone 24 to legs 22 configured to form a support surface of the support 2 on the support plane 21, these numerical references being visible in figure 11.
[0084] Preferably, a flat support is formed between the legs 22 and the plane 21. The feet 23 preferably have an inclination of between 20° and 60° relative to the support plane 21. Preferably, the central zone 24 extends along a plane parallel to the support plane 21. Still advantageously, the axis 14 is perpendicular to the support plane 21. And the plane 17 of the outer arch preferably comprises the axis 14. The lower part of the base is thus centered in its movement with respect to the support 2.
[0085] Figure 11 also shows that the base makes it possible to optimize the relative position of the machine 5 and the base to reduce the forces involved. In particular, the axis 34 can be judiciously placed at an intermediate height level of the machine 5 so as to distribute the weight of the latter around the axis 34 by forming a pendulum effect.
[0086] For example, one can consider a configuration of the assembly formed by the machine and the upper part of the base corresponding to a maximum load, that is to say when the barrel 52 is completely filled with targets 6. This maximum load configuration adds the fixed weight of the machine and the upper part, for example a total of substantially 70 kg, and that of a full load of targets, for example substantially 30 kg, corresponding to a maximum load of 100 kg. Conversely, a minimum load configuration corresponds to a situation in which the barrel is empty of targets, equivalent for example to a total load of 70 kg.
[0087] It is understood that the position of the center of gravity of this assembly changes when the machine is tilted. As a result, the moment of force exerted by its weight on the lower part of the base also varies, passing from a minimum value around a position in which the inner arch 3 is directed in the plane 17 to a maximum value when the inner arch 3 is in a position of extreme tilt, for example in the case of figure 11.
[0088] In addition to placing the axis 34 in an intermediate position depending on the height of the machine, which is permitted by the internal arch 3 whose concavity allows it to receive a lower portion of said machine, it is also possible to refine the position of the axis 34 so as to avoid too great a variation in the torque caused by the weight of the assembly between the maximum load and minimum load configurations.
[0089] To this end, the aim is to maintain the ratio between the weight of the assembly and the distance between a vertical axis G3y passing through axis 34 and a vertical axis G2y and G1y passing through the center of gravity of the assembly, respectively in the maximum load configuration and in the minimum load configuration, identical.
[0090] In the example of a maximum load of 100 kg and a minimum load of 70 kg, Figure 11 shows a determination of a distance between G3y and the two directions G1y and G2y such that: [G1 yG3y]*70 = [G2yG3y]*100.
[0091] As a more approximate option, we can simply place axis 34 at least between the directions G2y and G3y.
[0092] Furthermore, it is possible to arrange for the projection onto the support plane 21 of the direction G2y (vertical direction passing through the center of gravity of the assembly formed by the machine at the upper part of the base in the maximum load configuration) to always be inscribed within the surface of the central zone 24 of the support 2. This latter zone 24, thus cleverly dimensioned, ensures good stability, insofar as the unbalance of the machine is never too eccentric so that it does not risk tipping over. It is thus possible to dimension the ground surface area of the support 2 as best as possible, which can be, surprisingly, relatively reduced thanks to the invention and the optimization of the placement of the center of gravity of the mobile elements relative to the lower part of the base.
[0093] Figure 12 also reflects this arrangement, with the center of gravity Gt of the assembly in the maximum load configuration, and the direction G2y remaining inscribed in the surface of the central zone 24.
[0094] Figure 12 shows another option of the invention in the form of a counterweight 37. Indeed, the maximum load of the assembly carried by the lower part of the base can change, either during variations in the loading of the barrel 52, or depending on the type of machine that can be carried by the base. The machines do not all have the same weight. The counterweight 37 can equip the assembly carried by the arch 1 and in particular it can be mounted on the inner arch 3. According to the example of Figure 12, the counterweight 37 is fixed to the junction block 33. Preferably, to achieve a balancing effect with respect to the upper part of the machine 5, the counterweight 37 is located at the level of the lower portion of the inner arch 3.
[0095] According to an additional possibility, the position of the counterweight is adjustable in height, so as to vary its influence in terms of moments of force on the overall load produced by the assembly carried by the base. According to another possibility, cumulative or alternative, the counterweight is made removable on the base, so as to be able to use it only when necessary and / or so as to be able to mount a counterweight having the mass most suited to the situation.
[0096] The invention is not limited to the embodiments previously described.
