Description

FIELD OF THE INVENTION

The present invention relates to a target launching machine and a method of adjusting this machine.

It finds its application in the field of the projection of targets for shooting the trap-type for which targets are used in the form of saucer-shaped trays often called clay pigeons.

STATE OF THE ART

Machines have been known to launch targets for several decades. These machines generally use a rotary arm mounted launch arm, for example by a spring tension system, so that the release of the rotation of the arm, on command, generates a sharp movement of the arm. The latter intercepts a target placed on a projection surface and the target is projected at high speed.

In the most advanced machines, it is possible to launch a large number of targets without reloading the machine. For this purpose, the machine comprises a target storage magazine, the targets being delivered one by one to the projection surface. A store design includes a barrel having a rotational movement. The barrel incorporates a plurality of columns each for storing multiple targets in superposition. The rotational movement of the barrel ensures the sequential positioning of one of the columns facing a hole for the delivery of the lowest placed target in the column to the projection surface.

Generally, the sequential rotation of the barrel (whose angular pitch is a function of the number of columns) is coupled to the cycle of rotation of the arm, a cycle of the arm generating a movement of the barrel so as to place a next column next to the hole and thus by this circular movement, gradually empty the columns of the barrel.

On the basis of this technology, attempts have been made to provide a variety of shooting possibilities, so as to multiply the configurations of clay pigeon drills. One of the possibilities is to vary the direction of rotation of the throwing arm so as to produce a projection to the right or left of the machine. Machines have been proposed for which the arm, and thus also the barrel, rotate in the trigonometrical direction and, in addition to the machines for which the arm and the barrel rotate in the clockwise direction. It appears that you need several specific machines - at least two - to afford this variety of shots US 2002/112712 constitutes a relevant document of the state of the art.

There is a need to allow target launch variants, especially with different rotations of the arm without causing cost multiplication. There is also a general need to adjust the projection direction of the machines.

SUMMARY OF THE INVENTION

The present invention relates, in one aspect, a machine for launching targets, comprising a frame on which is mounted a support relative to which a cylinder is rotatably mounted along an axis of rotation, the cylinder comprising a plurality of target storage columns in stack, the columns each having a longitudinal axis parallel to the axis of rotation, the frame comprising a target receiving surface for launching, the support having a hole configured to allow the passage of a target from a barrel column to the receiving surface.

According to an advantageous aspect, the support comprises a first fixing position relative to the frame, and at least a second fixing position relative to the frame, the first position and the second position having an angular offset in a direction parallel to the axis of rotation. .

It is thus possible to adjust the projection direction of the target. This is particularly useful for compensating the effects of the inertia of the target passing through the hole. Specifically, the target in question passes through the hole having previously undergone a force, substantially tangential to the trajectory of the barrel, due to the rotation of the latter. The target does not fall on the receiving surface with the sole application of its weight, but also with a component related to its inertia in this movement induced by the rotation of the barrel. In practice, the target does not reach the receiving surface at the exact right of the hole, but slightly shifted.

The presence of two angular positions for the support makes it possible to move the position of the hole to take account of the natural shift of the target. One application of this adjustment is to allow operation of the machine either in a first direction of rotation of the arm, or in an opposite direction, while keeping the same direction of rotation of the barrel (and thus avoiding having to design and produce barrels dedicated to a unique direction of rotation of the arm). In practice, thanks to the invention, the user can use the machine in a direction of rotation of the arm corresponding to that of the barrel, then simply mount the arm (and possibly the receiving surface) so that the arm rotates in the opposite direction and produce a target launch on the other side of the machine. The barrel, meanwhile, remains in place and its direction of rotation is not changed. The position of the target falling on the receiving surface is simply corrected by changing the angular position of the support, so as to take account of the fact that the barrel and the arm turn this time in the opposite direction. This ensures a fixed starting position of the target relative to the arm, on the receiving surface. Only the direction of rotation of the arm is changed.

It then has a scalable machine with two directions of rotation of the arm by simply adding one or more supports to fix the receiving surface and especially using 100% of the original machine parts; the manufacturing is standardized.

The adjustment of a trajectory is obtained by an angular adjustment of the base of the machine vis-à-vis its support. It is a very simple operation and very fast. Changing the position of the barrel to achieve a similar effect would be much longer to implement especially if the machine is filled.

The invention is also related to a method.

With reference to the figure 1 , the machine of the invention may comprise a frame 1, for example metal allowing support on the ground or on any other surface of the machine. The frame typically has a lower bearing surface and supports a plurality of functional elements for launching the target. In particular, the chassis receives a motorization 7, preferably electric, allowing by a motion transmission system, to load a spring kinematically connected to a throwing arm 9. When the spring is loaded, a controlled trigger system allows to relax the spring and to ensure a sudden movement of the arm 9 so as to produce the launching energy of a target 13. It will be possible to use geared motors, springs and conventional launch arms in the context of the invention . An example of launching arm 9 is shown in Figures 1 to 4 with an axis of rotation 11 around which the arm is rotatably mounted when actuated to launch a target 13. A front portion of the throwing arm provides contact with a target 13. Overall, the throwing arm 9 can have a configuration substantially elongated between a proximal end at which the axis of rotation 11 is located and a distal end. The angular displacement of the throwing arm 9 is made partly above a receiving surface 12 at which at least one target 13 can be loaded so as to produce the launch. The distance offset along the axis of rotation 11 between the throwing arm 9 and the receiving surface 12 is adjusted so that the throwing arm 9 is applied to the edge of the target 13 to be projected. Preferably, the receiving surface 12 is perpendicular to the axis of rotation 11.

The actuating system of the throwing arm 9 operates in a cyclic manner so that, after the relaxation of the spring, the throwing arm 9 is brought from a rest position to a rearmed position by the intervention of the engine 7.

Such a machine allows the launch of at least one target 13 during such a movement. In order to make the machine autonomous in launching a large number of targets 13, the machine advantageously comprises a barrel 3 at which a plurality of targets 13 can be stored. More specifically, the barrel 3 comprises a plurality of columns 4, these columns extending in parallel with each other and being organized in an annular sector, at the periphery of the barrel 3, about an axis 10. The number of columns 4 is not limited. Each column 4 is for example delimited by rods 5 extending along the axis 10 and serving as a lateral abutment surface to the targets 13 which are stacked in each of the columns 4. Thus sets of targets 13 are superimposed on each other. In the upper part of the barrel 4, an upper frame 6b is advantageously positioned to connect together all the distal ends of the rods 5. In the lower part, the barrel 3 advantageously comprises a lower frame having the same function as the upper frame but to connect the proximal ends of the stems 5. The terms "inferior" and "superior" are, unless otherwise provided in this description, to mean a relative position of parts as compared to the action of gravity in the moving targets 13.

As shown, the lower frame 6a defines openings for each column 4 so that a target 13 placed in the lowest position in a column 4 can be extracted from the barrel 3 by its lower end. At this level, on the face of the lower frame 6a opposite to the rest of the barrel 3, is present a support 2 allowing the retention of the targets 13 in the columns 4, opposing the gravity. Preferably, to limit the friction, the support 2 comprises a retention surface 8, for example in the form of two annular portions extending along the path of the columns 4 about the axis 10 so as to produce a localized support of the lower face of the targets 13 placed in the lowest position of each column 4. The retention surface 8 advantageously does not extend along the entire angular movement of the support 2 so as to leave a lower level portion than that of the surfaces Retention 8 at the support 2. This part is illustrated as a transfer zone 19 at the level of the figure 10 . The barrel 3 is rotatably mounted about the axis 10 so that the columns 4 are advanced progressively according to this rotational movement. Advantageously, the rotational movement of the barrel 3 around the axis 10 is carried out sequentially with a step corresponding to 360 ° divided by the number of columns. Still preferably, the sequential movement of the barrel 3 is coupled to that of the throwing arm 9 so as to use a common motor for these two kinematics. Thus, each launching cycle of the arm 9 generates a movement of the barrel 3 sequentially by a determined step as a function of the number of columns 4.

The support 2 comprises, as shown in particular in figure 10 , a hole 14 through which a target 13 can pass from a column 4 of the barrel 3 to the receiving surface 12. The hole 14 is located on the trajectory of the columns 4 so that successively one of the columns 4 comes, at the level of its lower end, opposite the hole 14. In this way, the target 13 located lowest in column 4 in hole 14 can cross the latter and move to the receiving surface 12. During this movement, a retention system of the other targets 13 of the column 4 in question is provided.

With reference to Figures 5 and 6 and at the figure 10 , we explain in more detail the transit of a target 13 for projection. In a first step, the target 13 which is located lowest in one of the columns 4 moves during the successive movements of rotation of the barrel 3 around the axis 10, the target 13 being retained, against of its gravity, by the retention surfaces 8.

With reference to the figure 10 , having a barrel 3 rotatably mounted in the counterclockwise direction, the target 13 of the column 4 considered progressively reaches the transfer zone 19. The latter is advantageously located at a lower height level than the retention surfaces 8. These latter surfaces 8 may also be organized in the form of a ramp so that the level of the target 13 considered decreases progressively toward the transfer zone 19. Once on the transfer zone 19, the target 13 is shifted relatively to the rest of the stack of targets in the column 4 considered and continues its movement, in the trigonometric direction, towards the hole 14. At this level, the target 13 passes through the hole 14 and is found by its fall on the receiving surface 12. This mechanism is illustrated in Figures 5 and 6 . In particular, figure 5 , the target 13 is located on the transfer zone 19 and, continuing to be driven by the rotation of the barrel 3, gradually arrives at the hole 14. When the target 13 is sufficiently above the hole 14, it passes through the latter as represented in figure 6 . By gravity, the target 13 thus passes from the support 2 to the reception surface 12. The result obtained is illustrated in FIG. figure 7 .

The example of Figures 5 to 7 illustrates this advance of the target 13 and its descent on the receiving surface 12 and further schematically an offset between the situation of the target 13 at the end of its path, resting on the receiving surface 12 relative to the edge of the hole 14 So, the figure 7 shows a distance L ₁ between the upstream edge of the hole 14 relative to the direction of rotation of the barrel 3 and the upstream edge of the edge of the target 13 on the receiving surface 12. The distance L ₁ reflects that the kinetic energy of the target 13 has generated a shift relative to the right of the hole 14 so that the target 13 is not exactly opposite the hole 14 at the end of its transfer movement. This offset is not conducive to the precise adjustment of the launch of the target 13 insofar as the position of the target 13 on the receiving surface 12 is likely to change the launch trajectory by the throwing arm 9. moreover, if the machine is inverted, for use with rotation of the throwing arm 9 in the opposite direction, this shift has an effect opposite to the previous case on the relative position of the arm 9 and the target 13.

To limit the influence of this lateral shift of the target 13, one preferably uses an aspect of the invention in which the offset between the support 2 and the receiving surface 12 is very small, in the direction of the axis of rotation 10, so as to produce a significant decrease in the lateral offset between the hole 14 and the upstream edge of the target 13. The effect of this distance reduction between the support 2 and the receiving surface 12 is illustrated in FIG. figure 8 with a lag L ₂ greatly decreased. Preferably, the offset between the support 2 at the hole 14 and the receiving surface 12 is such that the residual clearance between the lower surface of the support 2 and the upper surface of the target 13 positioned on the receiving surface 12 is less than at 3 mm and preferably less than 2 mm. This dimension is marked "e" in figure 8 .

For example, the height of the target 13 may be of the order of 20 to 30 mm and for example of the order of 25 mm. An offset of 27 mm between the lower face of the support 2 at the area of the hole 14 and the upper face of the receiving surface 12 provides a residual clearance "e" of 2 mm.

Since the targets are of standard height in most cases, the offset can be set at the manufacturing stage. Optionally, an offset adjustment system may be incorporated.

According to another aspect of the invention, again in order to limit the shift of the target 13 during its loading in the receiving surface 12, the present invention may have, at the hole 14, a deflector 16 configured to limit the movement component of the target 13 passing through the hole 14 directed in the plane of the support 2. For this purpose, the deflector 16 has a configuration allowing a support on an area of the outer periphery of the target 13 to force the displacement the target 13 downwards, that is to say along the axis of rotation 10. Thus, it promotes the component of movements along the axis of rotation 10 for the target 13 by opposing the component perpendicular thereto by the support on the deflector 16. Preferably, the deflector 16 comprises an inclined flat surface, this inclination going out of the hole 14 when passing from the support 2 to the receiving surface 12. An example of e deflector 16 is presented in figure 9 . The situation of the latter on the support 2 appears in particular in figure 10 , in which figure the deflector 16 is situated at the edge of the hole 14. figure 11 shows another view of the deflector 16 in bottom view of the support 2. The inclination of the deflector is preferably between 30 ° and 60 ° and in particular 45 °. We understands that the deflector limits the advance of the target 13 on the receiving surface 12 during its fall. Thus, the offset between the hole 14 and the target 13 is still limited as reflected by the distance L ₃ represented in FIG. figure 9 . Advantageously and non-limitatively, both the baffle 16 and the approach between the receiving surface 12 and the support 2 are taken advantage of.

Without limitation, this adjustment capacity can be used to produce indifferently thanks to the invention a machine capable of launching targets by the right or left. The figures 1 and 3 show a first mode of use of the machine of the invention wherein the throwing arm 9 is mounted so as to have a rotation in a clockwise direction, the barrel 3 operating in the trigonometric direction. The figures 2 and 4 illustrate another mode of use of the machine of the invention in which the barrel 3 continues to rotate in the counterclockwise direction but in which the throwing arm 9 rotates in the trigonometric direction and no longer in the clockwise direction. Thus, in the case of figures 1 and 3 , the targets are projected by the left of the machine while they are projected by the right in the case of figures 2 and 4 . To achieve these two modes of operation of the machine, the present invention requires only slight modifications and in particular preferably the inversion of the launching arm 9 and the receiving surface 12.

Nevertheless, the present invention does not imply a modification of the system for storing and loading the targets on the receiving surface 12 and in particular the barrel 3 is not modified. Thus, it can be seen that in both operating modes of the machine, the barrel 3 continues to rotate in the same direction.

Preferably, at least one of the previously described aspects relating to the height difference between the support 2 and the receiving surface 12 and the presence of a deflector 16 is implemented so that, whatever the direction of rotation of the launching arm 9, the target 13 is brought on the receiving surface 12 almost from the hole 14 so that the inversion of the direction of rotation of the arm 9 does not influence the launch of the target 13.

As an additional or alternative to these aspects, the present invention may include a capacity of adjustment of the machine so as to modify the relative angular position between the support 2 and the frame 1 and compensate for the effect of the change of rotation of the arm 9. For this purpose, the support 2 is mountable on the frame 1 between a first position and at least a second position, these two positions having an angular offset along the axis of rotation 10 of the barrel or an axis which is parallel thereto. It is thus possible, for example, to compensate for the residual offset L ₂ or L ₃ or L ₁ of the target 13 in the two directions of rotation (it must indeed be remembered that in reversing the direction of rotation of the throwing arm 9 without reversing the direction of rotation of the barrel 3, the effect of the shift L ₁ , L ₂ , L ₃ is reversed for the relative position of the target 13 in position on the receiving surface 12 relative to the throwing arm 9).

To achieve the angular adjustment in the position of the support 2, the latter preferably comprises a first anchoring zone 17 and at least a second anchoring zone 18 at which the support 2 can alternatively be fixed on the frame 1. A As an example, the first and second anchoring zones 17, 18 may be holes passing through the support 2 and making it possible to constitute a point of attachment of the support 2 relative to the frame 1. Nevertheless, an oblong hole or another Continuous adjustment mode of the bracket angle may be suitable. Preferably, it also takes advantage of the holes 17, 18, to carry out the mounting of the axis of rotation 11 of the arm 9. Thus, two alternative positions are set to adjust the angular offset between the support 2 and the frame 1 while mounting the throwing arm 9 to rotate.

Note that the rotation axis 10 of the barrel is advantageously parallel to the axis of rotation 11 of the arm. Similarly, the angular displacement between the support 2 and the frame 1 operates around an axis parallel to the two previous ones.

The pivot of the support 2 between the two angular positions preferably operates along an axis parallel to that of rotation of the barrel 3. The figure 10 shows an example of location of the pivot axis 20 of the support 2.

The result of the invention is particularly surprising insofar as although using a barrel 3 always rotating in the same direction of rotation, one can realize two machine configurations (rotation of the trigger arm 9 trigonometric or hourly) without to disturb the direction of the shot. For example, in the illustration of Figures 3 and 4 , despite the reversal of the direction of rotation of the arm 9, the firing direction is unchanged in that the trajectories from these two modes of operation of the machine are parallel. The effect of the shift of the target 13 during its fall on the reception surface 12 has thus been completely annihilated.
