Definitions

  • the present invention relates to a new apparatus for tennis training which can be used, in general, for training in any other game in which a ball moving at high speed and over great distances is used, using it , as an effective collaborator both for beginners and for people already used to said games.
  • the apparatus according to the invention represents an important advantage over known "ball-throwing machines", in which it is necessary to have a large quantity of balls for their use, while with the apparatus currently claimed it only takes one ball, when it comes to training.
  • the new device according to the invention basically consists of a carcass whose general shape is parallelepiped, provided with side walls and whose front face is open, the assembly being mounted on feet, the height of the feet front can vary at will, while the rear feet advantageously have wheels that allow the transport of the device when not in use.
  • the side parts of the device are advantageously made of sheet metal, while the bottom consists of a net which begins at the front part of the device and extends to the rear part, subdivided into three zones, while being attached to the upper part to a flap, the inclination and geometry of which can be modified, to serve in various distinct uses.
  • the upper part of the device is also provided with a net, the ends of which can vary in position, which results in a change in the length of this net, thereby allowing to use also said part as an element of direction of the ball in the general use of the apparatus.
  • the player places himself at the front part and throws the ball against the inside, so that it strikes the nets which occupy the lower and rear part, which dampens the speed of the ball, by making it change direction according to the angle of incidence, so that, in any case, it falls outside by crossing the mouth of the device, while the upper hatch closes.
  • the new apparatus for tennis training is therefore extremely complete and allows to try and repeat a large amount of distinct games which ensures its wide use, and justifies its great usefulness.
  • the new apparatus for tennis training consists of a parallelepipedic structure of inclined rectangular tendency 1, mounted on four feet, the rear feet 2 of which are provided with wheels 3, to facilitate the transport of the device, while the front feet 4 have a lower part 5 connected to the rest by means of a pin 6 around which it can rotate, allowing the part 5 to be aligned aligned as an extension of the foot 4 whose height it increases or by tilting it backwards, when you don't want to use it.
  • the parallelepipedic element 1 which constitutes the general body of the apparatus, it is constituted by external uprights 7, the lower uprights of which extend forwards at 8, have a zone 9 joined to it front part by means of pins 10 while tie rods 11 hold it in position, said tie rod allowing the relative position of 9 with respect to 8 to have a variable angle.
  • a net 12 covers the device both at the bottom and at the back, it is subdivided into three zones, two of which are related, 43, 44, and, 45, the front part of 43 hanging so independent and being immobilized by a weight 14, and its opposite end being connected to the plate 47 while the upper end 15 of 44 is connected to a hatch 16 which closes the device at its rear upper part, while the rear part of the device is provided with a zone 17, the lower zone 18 of which can move at will by means of a hinge.
  • the apparatus also has a net 19, folded in two parts around a bar 20 and the end 21 of which is fixed by a tensioner 13, while the opposite end 22 moves on guides 23, thus making it possible to bring said ends apart or to separate them, by enlarging or decreasing the length of the net 19, which has the result that when the hatch 16 is open, the ball which leaves through the upper part slides on said net and comes to fall in soft fall in front of the player at a variable distance.
  • the rear hatch 16 it is fixed to a protruding element of the device 24, located in a position such that it can rotate about an axis 25, this rotation being facilitated by the existence of a rear element 26, joint, which, when pushed down, forces said hatch to rise.
  • this hatch fixed by means of a pin 27 whose end 28 is introduced into separate orifices which has the upright 29, which constitutes the extension of one of the rear legs of the structure.
  • the hatch itself, it consists of two rectangular blades 30 and 31, connected together with the possibility of turning around an axis 32, due to the fact that there is a bent metal wire 33, which avoids the separation of one with respect to the other when the hatch is closed, while thanks to the counterweight 34 which moves backwards when the hatch is raised to the maximum, it is possible, when desired , to move the plate 31 relative to the plate 30 and once it is perfectly open, to fix the part 31 in its position, thanks to the existence of another pin 35, the l end 36 is fixed in the rear upright opposite to the upright 29 to which the previously described pin is fixed. In this position, the ball rises almost vertically and strikes the net 15 which dampens its movement and the ball slides on the net 19, falling gently in front of the player.
  • a rectangular plate 37 fixed by means of an axis 38, around which it rotates.
  • this plate is joined by means of a cord or the like 39 to the plate 30 of the hatch 16, while the end of this cord, which is opposite to that by which it is fixed to the rectangular plate 37 , is connected by means of a spring 40, to the part 41 secured to the handle which moves the hatch, so that, when this hatch is closed, the part 37 bears against the net 44 and in this position, 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 37 and net 44 and this avoids dangerous rebounds.
  • FIG. 4 shows the way in which the new machine for tennis training is placed, once the hatch 16 and its two surfaces 30 and 31 separated from each other, by pivoting about the axis 32; at this moment, the rectangular plane 37 ceases to bear on the net 45 which, being pulled outwards by the hatch, exits through the upper part of the apparatus, allowing a once the hatch is perfectly fixed by means of pins 27 and 35, that the ball launched by the lower part of the apparatus, leaves outside by the upper part, falling while being braked at the top of the net 19 which directs it towards the player in a completely distinct position from that which occurs when one plays in the manner of a pediment, as that is represented on figure 1.
  • FIG 5 shows another view of the new apparatus according to the invention for tennis training, the hatch 16 being open, as well as the two plates 30 and 31, which constitute it, and which are parallel to each other.
  • FIGs 8, 9, 10 and 11 show a second embodiment of the upper hatch for closing the device, figures in which said hatch 48 is constituted by a longitudinal plane element, joined by means of two axes 49 and 50 to the general structure 1.
  • the displacement of this hatch is carried out by means of a rod 27 ′ which in this case has two orifices 51 and 52 to facilitate the introduction of the projecting axis 50.
  • the fundamental characteristic of the second embodiment of the hatch 48 resides in the fact that the hatch is divided transversely into two half-parts 51 and 53 joined by a hinge 54 which allow it to take the form of a roof, in s' ensuring that in this second position, its end 50 is perfectly inserted inside the corresponding orifice of the rod 27 ', 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, placed at the top of the hatch.
  • FIG. 12 represents a second embodiment of the structure 1 in which the front support 4 is offset towards the rear, leaving the front uprights 8 and 57 projecting, with the possibility of turning around their junction points 58 and 59 , which allows the entire structure to be folded.
  • the whole of the invention improves the arrangement of the front part of the net 12 which at its end is retained by a passing axis 60, forming a loop around it, a loop which is linked at the other end to another axis 61, movable thanks to a double part, located at its ends 62.
  • This part allows the net to move in arrangements which are shown in the two views of FIG. 13 where we can see how we can vary it so important the angle of the net and thus obtain different outputs of the ball, according to a more or less large parabola.
