Definitions

  • These devices propel the ball along a trajectory, of curved or tense shooting, according to the height adjustment of a guide corridor, with variable orientation according to the horizontal setting of the device.
  • the object of the present invention is a method and an installation for launching a balloon which makes it possible to give the balloon a left trajectory. It is characterized in that the balloon is printed, in the sending position, with a predetermined speed rotation about a predetermined axis.
  • Figure 1 is a sectional view of part of the installation, in this case, the support device of the ball.
  • Figures 2, 3, 4 and 5 are views of other embodiments of support devices.
  • Figures 6 and 7 show sectional views of one end of a percussion arm.
  • a hollow shaft 1 is supported by two bearings 2 and rotated by means of a pinion 3 connected to a motor by a transmission member, not shown.
  • the hollow shaft 1 supports, at its upper end, a support device 4 for a balloon 5.
  • the device is a concave plate, of diameter much smaller than that of the balloon 5, intended to position the latter rigorously.
  • the lower end of the hollow shaft 1 opens into a chamber 6 made hermetic by a seal 7.
  • a tube 8 opening into this chamber 6 is placed in communication with a suction system, not shown.
  • the closing of the concave plate 4 allows the suction system to create a certain vacuum therein via the circuit constituted by the tube 8, the hermetic chamber 6 and the hollow shaft 1 and thus ensure that the suction balloon is held very firmly. From this instant, the hollow shaft 2 can be driven in a rotational movement by means of the pinion 3 thus driving the balloon at a well-determined rotational speed.
  • a transmission member of a motor allows the pinion 3 to be driven at a speed which can be adjusted at will.
  • FIG. 2 represents a variant of the device making it possible to impart a rotational movement to the balloon 5 before kick-off.
  • This device consists of a centering ring 10 of diameter slightly smaller than the balloon 5, coaxial with two rods 11 and 12 respectively located above and below the balloon 5 along a same vertical axis, each terminated by a nozzle 15 and 16 much smaller in diameter than the balloon.
  • Two coil springs 17 and 18 are threaded respectively on the rods 11 and 12.
  • the rods 11 and 12 and the ring 10 are associated with each other by means of a frame formed by at least one vertical upright 19, by at least one upper horizontal arm 20, integral with the vertical upright 19 and at least one lower horizontal arm 21 sliding on the vertical upright 19.
  • the stroke of this rod 11 is limited by a stop 23.
  • the lower horizontal arm 21 supports at one of its ends a nozzle 24 in which the lower rod 12 slides.
  • the other end of the lower horizontal arm 21 supports at least one nozzle 25 allowing the arms 21 to move relative to the vertical upright 19.
  • the stroke of the upright 19 relative to the arms 21 is limited by a stop 26.
  • the lower horizontal arm 21 also supports the ring 10 by means of oblique uprights27.
  • the lower rod 4 integral with the nozzle 16, is driven in a rotational movement by means of a transmission device, not shown.
  • the end piece 15 pivots freely on the upper rod 3 which ends in a stop 28 receiving the thrust of the helical spring 17.
  • the frame formed of the arms 19 and 20 is in the raised position.
  • the ring 10 is pushed by the helical spring 18, via the lower horizontal arm 21 and the oblique upright 27, to occupy a high position allowing the ball 5 to be centered without it touching the end piece. 16 of the lower rod 12.
  • the frame formed of the arms 19 and 20 compresses the spring 17 by means of the nozzle 22 and thus ensures that the balloon 5 is held increasingly firm. Simultaneously the thrust of the stop 26 on the nozzle 25 progressively retracts the ring 10 and thus frees access to the balloon 5. The descent maneuver stops when the ring 10 arrives at the end 16 of the rod 12.
  • the rotation of the balloon by means of the lower rod 12 secured to its endpiece 16 is made by a motor device, not shown, giving the balloon 5 the desired speed.
  • L ? pressure of the helical spring 17 ensures the retention of the balloon 5 along a constant axis, materialized by the rods 11 and 12 and the pivoting endpiece 15 allows the balloon to rotate without driving the helical rod 11 rod 17 in the rotational movement.
  • the kick-off is given in a direction perpendicular to the plane of the frame formed by the elements 19, 20 and 21.
  • FIG. 3 shows another embodiment of the support device making it possible to impart a rotational movement to the balloon 5 before kick-off.
  • the hollow shaft 1, terminated at its upper end by a concave plate 4 is provided with a groove 30 and is provided with an oblong hole 31 at its lower part.
  • a tube 32, co-axial of the hollow shaft 1, mounted on two ball bearings 2, is provided with a hole 33 facing the hole 31 in the hollow shaft 1 and is provided with a positioning screw 34 which secures the tube 32 to the hollow shaft 1.
  • the bore of the tube 32 allows the hollow shaft 1 to slide axially therein with greasy friction, for a height adjustment with respect to the striking mass.
  • the tube 32 is rotated by means of a pinion 3 connected to a motor by a drive device not shown.
  • the transmission of the rotational movement from the tube 32 to the hollow shaft 1 takes place by means of the screw 34, the end of which is engaged in the groove 30 of the hollow shaft 1.
  • the groove 30 formed in the shaft hollow 1 is of such a length that it allows the displacement of the hollow shaft 1 with respect to the tube 32 over a sufficient height for the concave plate 4 to present the balloon 5 at the different levels required and thus the impactful mass 9 prints the desired trajectory effects on the balloon.
  • the balloon 5 is held on the concave plate 4 by suction through the tubing 8 and the circuit consisting of the hollow shaft 1 and the holes 31 and 33, respectively made in the hollow shaft 1 and the tube 32.
  • the balloon support device 5, constituted in FIG. 1 by the concave plate 4, can be replaced by other variants shown in FIGS. 4 and 5. These variants can be used with or without a suction device. However, the descriptions given below relate to the use of a suction system through the hollow shaft 1.
  • FIG. 4 represents a sectional view of a variant of the device for supporting the ball 5.
  • It consists of a hollow shaft 1 terminated by a shoulder 35 on which a helical spring 36 is supported and a basket 41 centered on the hollow shaft 1 by means of the helical spring 36 and articulated with respect to this hollow shaft 1 via a ball joint.
  • This ball joint comprises a convex part 37 made integral with the shoulder 35 and provided with a hole 38 coaxial with that of the hollow shaft 1 and a concave part 39 fitted with a hole 40 and secured to the basket 41.
  • the coil spring 36 After firing, the coil spring 36, if stiff enough to avoid oscillations of the rotation device, center the basket 41 again on the hollow shaft 1 and the process can start again.
  • FIG. 5 represents a sectional view of another variant of the device for supporting the balloon 5.
  • the latter consists of a hollow shaft 1 terminated at the end by a plate 42 carrying over its entire periphery a brush 43 formed of stiff bristles.
  • the implantation of the bristles of the brush 43 is of sufficient density for the brush 43 to present, under the weight of the balloon 5, a deformation in spray which gives a contact surface with the balloon 5, making it possible to drive the latter at the desired speed.
  • the brush 43 is lined over the entire periphery with a thin strip 44 of elastic material, the height of which is approximately equal to half the length of the bristles of the brush 43 This elastic strip 44 further contributes to increasing the stiffness of the bristles of the brush 43.
  • the retractable part of the support device consists of the bristles of the brush 45 and of the strip 44 which, when fired, deform elastically under the force developed by the ball.
  • the percussion device 9 consists of a roller free to rotate on an axis capable of be oriented in different directions.
  • FIG. 6 represents an exemplary embodiment of the percussion device. It consists of a bent arm 50, provided at its end with a hole 51_in which a lug 52 secured to a stirrup 53 is threaded until abutment of the shoulder 54.
  • the stirrup 53 carries an axis 55 around which pivots a percussive mass 9, of small diameter, of small mass and with rounded edges so as not to injure the balloon on impact.
  • the adjustment of the orientation of the axis 55 is obtained by making pivot the pin 52 in the hole 51 of the percussion lever 50.
  • the orientation of the axis 55 is maintained by a fixing device 56.
  • the left trajectory of the ball can also be obtained by giving the striking mass a rotation of suitable direction and of adjustable speed according to the effect sought in the trajectory.
  • Figure 7 is an exemplary embodiment of this other method.
  • the axis of rotation 55 of the percussive mass 9 is mounted on two needle bearings 57 and has an end piece 58 on which is threaded a flexible hose 59 held on the end piece 58 by a fixing device 60.
  • a motor gives the striking mass 9 a rotational movement in the direction and at the desired speed by means of the hose 59 made integral with the endpiece 58 by means of the fixing device 60.
  • the latter In order not to thwart the rotational movement imparted to the striking mass 9, upon impact with the ball in the sending position, the latter is held on a support device, free to pivot along an axis parallel to the axis 55 of the striking mass 9.
  • the rotational movement can be transmitted to the striking mass 9 via a gear train.
