Definitions

  • the present invention relates to a new apparatus for tennis training, but which can be used, in general, for training in any other game in which a ball moving at high speed over long distances is used; this device is used as an effective partner, both by beginners and by people already used to these games.
  • the apparatus according to the invention has an important advantage over known "ball-throwing machines", which require, for their use, a large quantity of balls. It requires only one ball for training.
  • This important advantage results from the fact that even if one of the ball throws is badly directed, it still penetrates inside the device, due to the width of the mouth of it, a beginner can be placed less than two meters from the device.
  • This device provides a game that is both educational and entertaining and can be applied to a large number of different games. This is not the case, for example, of the apparatus described in document WO-A 8 001 650, which comprises inclined lateral uprights and supported by feet, a fabric stretched between the lateral uprights, the apparatus having a cover shape at its upper part; this cover allows the bounce of the ball.
  • This device does not include means for holding the ball in an area facing the player; it follows that the player must show great skill in order to train with only one ball; if his address is unimportant, this player must have a large quantity of balls, to avoid picking up any ball lost as a result of an awkward stroke.
  • This known device is also not very adaptable to a large number of different games.
  • the invention remedies these drawbacks by proposing an apparatus, in which, after the ball has entered it, it cannot come out of it randomly because it is always directed towards one of the exit paths planned; these again direct the ball into the area where the player is located, who can then resume playing in peace.
  • the apparatus consists of a receptacle defined by uprights forming a structure of parallelepipedic external shape, closed on its sides and supported by four feet, a pair of which carries movable parts which can allow them to vary their height, and whose lower upright of the structure comprises a front extension articulated in its junction part and which is provided with a tie rod making it possible to make the whole rigid, this extension as well as the rest of the uprights facilitating the support of a net which, subdivided into various different zones and having a shape with a parabolic tendency, closes the apparatus both at the lower part than at the rear part, and which is extended to the front part by the front part and remains immobilized by means of a counterweight placed at its lower part, said net remaining stretched at its rear part by a transverse plate in its first zone, while the end of a conde zone is fixed to a tilting hatch closing the device at its upper rear; this hatch having another net which hangs from one of the plates which form it, while the rest of the upper surface
  • the player stands opposite the front part and throws the ball inwards, so that it strikes the nets which occupy the lower and rear parts; the speed of the ball is damped and the ball changes direction depending on the angle of incidence; in any case, the ball reaches the outside by crossing the mouth of the device, even when a flap, located at the top, is closed.
  • the hatch is provided with an operating rod provided with two orifices.
  • the second hole allows it to be fixed in position thanks to a protruding stud; it follows that when the hatch is open the two half-parts can have the shape of a double-pitched roof; the ball which reaches the hatch can then be returned with a different inclination depending on the position of the slope of the roof that it strikes.
  • the new device especially for tennis training, is therefore very complete and also makes it possible to try and repeat a large quantity of distinct games, which ensures its wide use, and justifies its great usefulness.
  • the new device according to the invention for training in a game of ball and in particular in tennis has a rectangular parallelepidedic structure 1, inclined, mounted on four feet; the rear feet 2 are provided with wheels 3, to facilitate the transport of the device, while each front foot has a lower part 5, connected to this foot by a pin 6 around which this lower part can pivot; this pivoting makes it possible to place the part 5 in the extension of the foot 4 (FIG. 2) and thus to increase the height of the foot 4.
  • the lower part 5 is inclined backwards.
  • the paralleledipedic structure 1 which constitutes the general body of the apparatus, comprises external uprights 7, the lower front parts of which extend forward at 8 (FIG. 3); each external upright comprises an arm 9 joined to the lower front part 8 by means of a pin 10; a tie rod 11 retains this arm in position so that it makes it possible to adjust the relative position of the arm 9 with respect to the front extension 8 of the upright 7.
  • This arm and this tie rod thus have a variable angle.
  • a lower net extends in the device, both at the lower part than at the rear part; this net is subdivided into three zones 43, 44, 55, two of which are related (43 and 44).
  • the front part of the zone 43 hangs freely and is ballasted with a mass 14; the upper end 15 of the zone 44 is connected to a movable hatch 16 extending transversely and which closes the device at its rear upper part.
  • the rear part of the device is provided with a transverse cover 17 whose lower part 18 can move at will by means of a hinge, this cover is located below the hatch 16, facing the player.
  • the apparatus also comprises an upper thread 19, folded in two parts around a transverse bar 20.
  • the upper end 21 of the thread 19 is fixed by a tensioner 13, while the opposite lower end 22 moves on guides 23, thus allowing the said ends to be brought closer or further apart, by enlarging or decreasing the length of the thread 19.
  • the hatch 16 is open, the ball comes out through the opening thus formed in the upper part of the apparatus for sliding on the net 19 and falling in a damped fall in front of the player, at a variable distance.
  • this is fixed to a means 24 for controlling the rotation of the hatch projecting relative to the device and being able to rotate about an axis 25.
  • This rotation is facilitated by the existence of a posterior element 26, joined to element 24, which, when pulled down, forces said hatch to rise, as shown in FIGS. 4 and 5.
  • the hatch 16 is retained by means of a rod 27, the end 28 of which is introduced into one of the separate orifices presented by an extension 29 of one of the rear legs 2 of the structure.
  • the hatch 16 proper it consists of two rectangular plates 30 and 31, hinged together by a hinge 32.
  • a bent metal lug 33 prevents the separation of the two plates when the hatch is closed.
  • a counterweight 34 which moves rearward when the hatch is raised to the maximum, allows, when desired, to move the plate 31 relative to the plate 30 so as to place it in a perfectly open position relative to the plate 30 It is then possible to hold the plate 31 in its position, thanks to another rod 35, one end of which 36 is fixed to an extension of a rear leg, opposite to the extension 29 to which the rod 27 described above is fixed. In this position, the ball rises almost vertically and strikes the net 15 which dampens its movement, then the ball slides on the net 19, falling gently in front of the player.
  • the rear part of the device also comprises a transverse rectangular flap 37 fixed to an axis 38 around which it can rotate. In its lower part, this flap is joined, by a cord or the like 39, to the plate 30 of the hatch 16. The end of this cord, opposite the end by which it is fixed to the rectangular flap 37, is connected by a spring 40, to a part 41 integral with a handle 26 which allows you to move the hatch.
  • the flap 37 bears against the net 44; in this position, we can play as if it were a pediment, by throwing the ball against a hard surface, while when the hatch is open, contact ceases between the flap 37 and the net 44 and we avoid thus dangerous bounces of the ball.
  • This second embodiment of the hatch 48 lies in the fact that the hatch is divided transversely into two rectangular plates 51 and 53 joined by a hinge 54 and directed from the rear to the front of the structure. This allows this hatch to take the form of a double-pitched roof, ensuring that the axis 50 is perfectly introduced inside the corresponding orifice of the rod 2T, by means of a spring 55.
  • the movement of the rod 27, is transmitted to the hatch 48 by means of an articulated bar 56 fixed at 57 to the plate 52, placed at the top of the hatch.
  • FIG. 12 represents a second embodiment of the structure 1 in which the front leg 4 is offset towards the rear, allowing the front uprights 8 and 57 to protrude which can rotate around their junction points 58 and 59 so that the whole structure can be folded.
  • An improvement in the overall structure of the device can be made by virtue of an axis 60 around which the front part of the net 12 forms a loop. A portion of this loop, close to the end of the net passes over another axis 61.
  • This axis 61 is made movable by a double part 62. This part makes it possible to move the net according to the positions shown in the two views of the figure 13. These views show how it is possible to vary the angle of the lower zone of the net significantly with respect to the ground and thus obtain different directions of the ball, according to a more or less stretched parabola.
