Definitions

European patent 80200346.7 describes, through a few exemplary embodiments, a device in which the percussion lever is of low mass and which is arranged to recover, before impact with the ball, the kinetic energy accumulated by the other elements of motion transmission.
a player modifies the point of impact on the ball so that it is animated by a rotational movement around an axis which depends on the position of the point d impact relative to the center of gravity of the ball.
European patent 79200221.4 describes a device which gives a left trajectory to the balloon by imposing on the latter, in the sending position, a rotation of predetermined speed around a predetermined axis.
the positioning cup which, by suction, firmly holds the ball before kick-off and / or the size of the drive device, possibly giving this positioning cup a rotational movement at a determined speed it may be that despite an adjustment in height of the positioning cup the percussive mass of the balloon launcher does not strike the balloon low enough to obtain the desired type of trajectory.
the primary trajectory given to the ball by the impact of the striking mass must be modified by an appropriate device.
the usual way is to arrange an inclined plane according to a chosen slope at a determined level.
the contact between the balloon and the inclined plane communicates to the balloon a rotation about a horizontal axis perpendicular to the greatest slope of the inclined plane.
This rotation modifies the trajectory of the ball by shortening its point of fall and gives a false rebound.
the ball is felt more harshly.
the modification of the coefficient of friction between the ball and the inclined plane depending on whether both are dry, wet, covered with mud ... the trajectory is not very repetitive during successive shots.
the present invention overcomes the various drawbacks mentioned above thanks to the fact that the percussive end of the percussion lever is shaped to have several points of impact simultaneously striking the ball and arranged symmetrically with respect to a plane passing through the departure path of the ball.
the symmetrical arrangement of the impact points of the percussive end with respect to the plane perpendicular to the axis of suspension of the lever passing through the balloon's departure trajectory compensates for the surface irregularities of the balloon and greatly reduces the deformation of the outer envelope thereof In this way, this device improves the precision of the trajectory of the balloon.
Figure 1 shows an embodiment of a percussive mass 1 distributed at several points.
a percussion lever 2 is terminated by a fork made up of two teeth 3 each equipped, at the free end, with an axis 4 intended to receive two rollers 5 free to rotate around this axis 4.
the orientation of each axis 4 is approximately parallel to the axis of rotation along which the ball turns when wants to communicate a left path to it.
Each axis 4 is therefore parallel to the axis of rotation 6 ′ of a presentation device 7 for the balloon 8 .
the balloon 8 shown in phantom is placed on a small diameter cup 9 connected to a non-suction system shown which maintains the balloon 8 on the cup regardless of the speed of rotation of the presentation device 7.
the orientation of the teeth 3 of the fork can be adjustable by an appropriate device for modifying the points of impact of the rollers 5 on the ball 8.
the balloon 8 When the striking mass hits, by means of the four rollers 5, the balloon 8 simultaneously at four points, the deformation of the outer envelope of the balloon 8 is slight and practically does not interfere with the rotation given beforehand to the balloon 8 along the axis 6 In addition, the striking of the ball, distributed in several points, requires less of its envelope and thus contributes to reducing wear.
FIG. 2 represents an exemplary embodiment of the device for modifying the trajectory of the balloons.
a stirrup 10 made integral with the frame II by fixing means comprises two branches 12 arranged symmetrically with respect to the plane defined by the arrival and departure trajectories of the ball.
This bracket 10 serves as a support for a movable assembly 13 which can oscillate around a horizontal axis 14, 'placed perpendicular to the plane defined by the first and modified trajectories of the balloon to occupy either a high position or a low position as shown in Figure 2.
This movable assembly 13 comprises two forks 15 each threaded on a branch 12 of the stirrup 10 and joined together by a flat 16.
Each fork 15 carries an axis 17, parallel to the axis 14, around which a roller 18 freely pivots These rollers 18 occupy a symmetrical position relative to the plane perpendicular to the axis 14 passing through the modified trajectory of the balloon.
balloon 8 When balloon 8 is fired, it strikes the rollers 18 which, according to the adjustable position of the mobile assembly 13 deviates more or less strongly the first trajectory. of the balloon to give it a modified, more ascending trajectory.
the rollers 18 are of small diameter and of low inertia.
the position of the rollers 5 and 18 is symmetrical both to the plane of movement of the percussion arm 2 and to the shooting axis of the ball.
the symmetry with respect to the plane of movement of the percussion arm 2 ensures, on the one hand, good centering of the balloon 8 when the rollers 5 release it from the positioning cup 9 and project it forward.
the symmetry with respect to the firing axis allows, on the other hand, the rollers 18 to maintain the correct guidance of the balloon 8 when it crashes on these rollers and then reshapes resiliently to resume a more ascending trajectory.
the rollers are cylindrical in shape with strongly rounded edges so as not to damage the balloons.
the shape, the diameter or the number of rollers can vary as long as the principle of a symmetrical arrangement with respect to the plane of movement of the percussion arm is respected.
the rollers 5 and 18 can be of frustoconical or hyperbolic shape.
the invention is in no way limited to the examples of realization described by way of example.
it includes all the technical equivalents executed according to its spirit and in particular percussive masses according to the invention which are not mounted on the end of a percussion lever, but for example on the end of a piston.
