Definitions
- the present invention relates to the field of target launching machines. It finds a particularly advantageous application in the shooting sport industry, and in particular clay pigeon shooting.
- An object of the present invention is therefore to provide a machine base, and a launching machine system equipped with such a base, offering improved mobility of the machine relative to the base.
- a base for a target launching machine comprising: • a lower part;
- the base is such that:
- the lower part includes an outer arch
- the upper part includes an inner arch nested in the outer arch
- the base has a double arch configuration allowing optimized travel of the upper part relative to the lower part.
- the optimization is aimed at obtaining a greater angular amplitude, in particular to obtain extreme trajectories for the targets.
- the optimization relates to a better distribution of the loads applied to the inner arch, in particular to limit the forces that the actuator must apply.
- the standard targets are indeed discoidal in shape and provided with a domed cap and except in the trajectories flying over the shooter, the orientation of the target in flight exposes in practice only its lateral profile to interfere with the sheaf of pellets, which gives a certain complexity to the shots.
- the arched shape also makes it possible to have significant rigidity in a preferred direction by limiting the overall volume of the part equipped with this arch, lower part or upper part.
- the lower part of the interior arch and preferably a majority of the height of the interior arch, is integrated into the interior volume of the latter, when the interior arch is in the same plane as the arch exterior. This shape is also favorable to as large a movement as possible of the inner arch during its rotation.
- Another aspect relates to a target throwing system comprising a target throwing machine and a base as shown herein, the target throwing machine being carried by the base.
- Figure 1 shows a front view of a system comprising a base and a launch machine loaded with targets.
- Figure 2 shows a rear face view of this system.
- Figure 3 shows an embodiment of the base, isolated from the machine it carries, in perspective.
- Figure 4 shows the base in the embodiment of the previous figure, with an inclination of the inner arch.
- Figure 5 shows an example of the mobility of a base of the base.
- Figure 6 is a second illustration of this base mobility.
- Figures 7 to 9 show a plurality of non-limiting possible firing positions by varying the mobility of the base.
- Figure 10 reflects mobility relative to a support.
- Figure 11 illustrates in profile an indicative extreme position that can be reached thanks to the invention.
- Figure 12 shows an embodiment with counterweight.
- the outer arch 1 comprises a first arm 11 and a second arm 12 extending on opposite sides of the outer arch 1; wherein the inner arch 3 comprises a first arm 31 and a second arm 32 extending on opposite sides of the inner arch 3, and wherein the rotation of the inner arch 3 in the outer arch 1 is effected by a first pivot between the first arm 11 of the outer arch 1 and the first arm 31 of the inner arch 3 and a second pivot, opposite the first pivot, between the second arm 12 of the outer arch 1 and the second arm 32 of the inner arch 3;
- the actuator 35 has one end mounted on the inner arch 3 and another end mounted on the outer arch 1;
- the actuator 35 is a jack having a stroke perpendicular to the swing axis 34;
- the base comprises a support 2 on which is mounted the outer arch 1 and in which the support 2 comprises a lower support surface according to a support plane 21, and in which the swing axis 34 is parallel to the plane;
- the outer arch 1 is rotatably mounted on the support 2 along a primary axis 14, the base comprising a primary actuator 15 configured to control the rotation of the outer arch 1 relative to the support 2;
- the primary axis 14 is perpendicular to the swing tilt axis 34 and/or the primary axis 14 and the swing tilt axis 34 are concurrent;
- a base 4 is mounted on the inner arch 1 and comprises a support zone for the machine 5 for launching targets;
- the base 4 is rotatably mounted on the inner arch 3 along a secondary axis 44, the base comprising a secondary actuator 45 configured to control the rotation of the base 4 relative to the inner arch 3;
- 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;
- the base 4 comprises a plurality of anchor points 47, preferably four anchor points evenly distributed at 90° around the secondary axis 44, each configured to interchangeably mount one end of the secondary actuator 45 ;
- the upper part comprises a counterweight 37, preferably removably mounted.
- the target launching machine 5 comprises a barrel 52 for storing targets, and the system comprises a maximum load configuration in which the barrel 52 is completely filled with targets 6, and a minimum load configuration in which the barrel 52 is completely empty of targets 6;
- 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 axis of swing 34 being located so that a torque value exerted by the weight of the assembly, in the direction of the axis of swing 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;
- 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 .
- the expression “substantially equal” means a value which is not more or less than 10% different from another value.
- the arched shape offers a concave geometry. “Nested” means that the inner arch is mounted so that it can struggle in the concavity of the outer arch. Typically this interlocking 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 protruding beyond the outer arch, especially 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 profiles concaves of the two arches being oriented on the same side.
- the invention presented here comprises a machine 5 configured to launch 6 targets.
- the latter can be of the clay pigeon type, which have a circular section, in the form of a plate and which are generally used for the practice of clay pigeon shooting.
- This application is not limiting.
- targets made of polymer material for the practice of archery on a moving target is another possible application.
- the machine 5 comprises a launching part 51 .
- a target ready for launch is generally placed on a launch plane 511 to be projected by an arm 512 mobile in rotation and controlled by a motorized arming and triggering system.
- the barrel 52 is arranged above the launch part 51 and it has means for the successive delivery of at least one target 6 thus removed from storage, in the direction of the launch plane 511 .
- 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 tens of targets 6. It is easy to understand that the weight of the machine 5 is substantial, especially when many targets are stored. For example, the weight of an empty 5 machine can be 70 kg, and the maximum load of targets can be 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 can include very inclined positions of the machine relative to the base, as can be seen for example in figures 11 and 12.
- the base presented here comprises from a support plane 21 typically corresponding to the ground, a support 2 carrying an outer arch 1.
- This set typically belongs to a lower part of the base. It is surmounted by an inner arch 3 mounted movable relative to the outer arch 1.
- the inner arch 3 itself carries a base 4 at which the machine 5 is received.
- the inner arch 3 and the base 4 belong to an upper part of the base which is thus mobile relative to the lower part.
- Figures 1 and 2 show an actuator 35 making it possible to control this mobility. They also reveal a primary actuator 15 allowing to control a relative mobility between the support 2 and the outer arch 1, as well as a secondary actuator 45 allowing to control a relative mobility between the inner arch 3 and the base 4.
- 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.
- At least one of the actuators 15, 35,45 is a jack, and preferably an electric jack.
- 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 position variations.
- outer arch 1 can be made in the form of a profile, either in one piece or from an assembly of a plurality of elementary profiles.
- the cross section of the outer arch is rectangular, and more precisely square.
- 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 mid-length of the outer arch 1. As will be seen later, the block 13 also gives preferentially the possibility of making a connection to the support 2.
- the length of the interior arch in projection on the support plane 21 can be greater than or equal to 80 cm and/or less than or equal to 150 cm.
- 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 along the section of the branches. It will be seen that this plane can include an axis of rotation 14 of the arch 1 relative to the support 2.
- the outer arch 1 also has symmetry along a plane 17 shown in Figure 3 and extending vertically by intersecting the arch 1 in the middle of its width.
- 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 allows the use of hollow elements limiting the weight of the arch 1 . At the same time, there is a satisfactory rigidity.
- the outer arch 1 defines, between these two distal ends 111, 121, a concavity facing upwards forming a clearance space for the upper part, and in particular for the inner arch 3.
- This clearance is allowed around a swing axis 34 shown schematically in Figure 4; typically, pin 34 is horizontal in a position of usual 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.
- 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.
- another end 321 of the inner arch 3 is connected to a other end 121 of the outer arch 1 by another pivot connection which can be materialized by a shaft 342.
- the arch 3 may comprise a first branch 31 and a second branch 32 fixedly connected via a junction block 33 advantageously located in the center of the inner arch 3 and opposite the block of junction 13 in the situation of figure 3.
- 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.
- 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 the figure 3.
- 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.
- a basal part of each of the arches, at the level of the junction blocks, is straight, so that the two arches are parallel at this level in a direction parallel to the axis 34.
- FIG. 3 and 4 make it possible to visualize this command by a movement of the rod 352 of this actuator 35 relative to its body 351 .
- one end of the actuator 35 is mounted on the outer arch 3, here via 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, via 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 of figure 4.
- figure 11 and figure 12 give two examples of the result produced by this inclination, examples in which the arch 3 has a non-zero angle relative to the 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.
- the base comprises a base 4 carried by the inner arch 3.
- the base 4 can 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.
- a pivot 43 makes it possible to adjust the inclination between the upright 42 and the plate 41 thus offering an additional adjustment capacity to the orientation of the machine 5.
- 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 of the rod 452 in the figures.
- a displacement in translation 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 such as visible in particular in Figures 4, 5 and 6 and arrows illustrating rotation in Figures 5 and 6.
- the actuator 45 can be mounted on the base 4 at different places on the plate 41 corresponding to the anchor point 47 referenced in FIGS. 5 and 6.
- the actuator 45 can modify the angular sector of displacement in rotation of the base 4 relative to the inner arch 3 and this, for a limited actuator stroke 45.
- the stroke is configured to be able to produce a movement of 90°
- the positioning of four anchor points 47 spaced 90° apart on the plate 41 allows a capacity for 360° movement of the base 4 relative to the arch. interior 3.
- a pivot is preferably positioned in the center of the plate 41 vis-à-vis the junction block 33.
- Figure 7 shows an example of orientation of a machine 5 thanks to the base of the invention.
- the arrow which is visible there shows in particular that it is possible to project a target 6 by the arm 512 very inclined downwards, the launching plate 511 being very inclined in this case.
- Figure 8 shows a very different orientation of the firing direction by an arrow pointing strongly upwards, the base 4 having been turned by the actuator 45 relative to the position of the Figure 7.
- 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 anchor point of the latter .
- FIG. 10 diagrams another capacity for optional movement, between the support 2 and the outer arch 1.
- mobility in rotation is advantageously allowed between these two parts around an axis 14.
- pivot is organized between the support and the junction block 13 and the actuator 15 controls the rotation.
- 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 via 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.
- the support 2 comprises a plurality of feet 23 extending from a central zone 24 to legs 22 configured to form a bearing surface of the support 2 on the support plane 21, these numerical references being visible in FIG. 11 .
- a plane support is formed between the tabs 22 and the plane 21 .
- the feet 23 preferably have an inclination of between 20° and 60° relative to the support plane 21.
- the central zone 24 extends along a plane parallel to the support plane 21 .
- the axis 14 is perpendicular to the support plane 21.
- the plane 17 of the outer arch preferably includes the axis 14. The lower part of the base is thus centered in its movement vis-à-vis -bracket screws 2.
- FIG. 11 also shows that the base makes it possible to optimize the relative position of the machine 5 and of the base to reduce the forces involved.
- 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.
- 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 cylinder 52 is completely filled with targets 6.
- This configuration of maximum load 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.
- 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.
- the projection on 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 configuration of maximum load) is always inscribed in the surface of the central zone 24 of the support 2.
- This last zone 24, thus cleverly dimensioned, ensures good stability, insofar as the unbalance of the machine is never too off-center so that 'She's in no danger of tipping over. It is thus possible to size the surface as well as possible. ground occupation of the support 2, which can be, surprisingly, relatively small 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.
- Figure 12 also reflects this arrangement, with the center of gravity Gt of the assembly in maximum load configuration, and the direction G2y which remains inscribed in the surface of the central zone 24.
- Figure 12 shows another option of the invention in the form of a counterweight 37.
- the counterweight 37 can equip the assembly carried by the arch 1 and in particular it can be mounted on the inner arch 3.
- the counterweight 37 is fixed to the junction block 33.
- the counterweight 37 is located at the level of the lower portion of the inner arch 3.
- 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.
- the counterweight made in a removable manner 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 most suitable mass for the situation .
