The present invention "relates to a device for g

Collecting tennis balls from one on a playing field |

arranged ball throwing device. |

Door practice purposes, especially for beginners, are provided at t

Tennis often uses ball throwing facilities that target h

be placed on one side of the net on the playing field |

and constantly throwing balls to the practitioner, which the practitioner hits ^? the other side of the network has to play. The balls are released in short order and in large numbers,

which, however, is also connected with the fact that the practitioner then

send all the balls that are available and dispensed, j who must collect again, whereby a considerable period of time for the Practice is lost.

The object of the present invention is to provide a device i

of the type mentioned at the beginning, with which it is possible:

will, at least the majority of the balls played i

to collect again. 1

For this purpose, a single is provided according to the invention, |

which is placed along the back of the tennis court, |

wherein the one is funnel-shaped. Under trich- |

The area of the deepest part of the one is located

direction for transporting the balls to the court surface |

and especially for the handover to another ball throwing \

device which is arranged in such a way that the balls \

can pass.

Usually there are nets on the back of a playing field or the like. arranged of which the balls when they hit this hit, fall down, these balls are picked up by the gutter, roll to their lowest point, where the device for transporting the balls to the surface of the court is is located, are transported with this to the surface of the court and to another ball throwing device adjacent to the channel to hand over.

Although this ball throwing device can be used directly to pass balls to the practitioner, since this ball throwing device but must be located on the back of the playing field - otherwise openings had to be in the area of the playing field in which players would move in a normal game, so that the playing field is only for practice | purposes would be available - the balls reach too high a speed for beginners and can use them not be played. For this reason, the balls are expediently from the ball throwing device on the back side of the tennis court to the ball throwing device arranged on the playing field. The latter can be used for this purpose have a collecting funnel at their upper end, which is preferably formed from a bed in order to ensure safe entry. ensure catching the balls.

Although the vast majority of the the ball throwing device located on the field of play. Balls can be seeded, it is also preferred to arrange an additional funnel-shaped collecting channel in the area of the fletzes in the middle of the playing field, which is connected to the Binne is connected to the back of the tennis court via a drill that runs under the surface of the court with a slope.

In this way, almost all balls can be collected automatically and released again from the ball throwing device for practice so that the (tennis player practically no practice time loses more by picking up bales.

You sense at the back of the tennis court can be made up of several There are funnel-shaped sections, with a funnel-shaped section being formed as the deepest, with which the other are connected, with the device in the deepest section, into which all of the collected balls finally roll «To transport the balls to the court surface and to handover to the further ball throwing device on the buck side of the Place is arranged, wherein the latter can consist of a rotatable disk "which is in operative connection with a vertical tube stands and the age of the balls in the tube are pushed upwards, however, can also be a device with the. the balls are transported up via an Archimedean spiral, are used.

Openings in the movement of the players in the upper surface can be avoided according to the invention.

The invention is described below with reference to the appended in FIGS Illustrations illustrated embodiment explained in more detail.

device 4 facing away from the Eetzes 3 is a collecting device 5 in the form of a one above the playing field surface provided, which, however, could also be embedded in the ground, whereby the senses 5 are inclined, for example, to one side or approximately from the ends towards the center, i.e. designed in the shape of a funnel is. The channel 5 stands above an inlet 6 with a box 7 in the bottom 8 of the playing field 2 in connection. Balls made by the Practitioners are hit against the net 3, fall into the channel 5 and roll from this into the box 7-

At the back of the tennis court there is a channel 1o, which according to FIG. 2 in the illustrated embodiment consists of a plurality of funnel-shaped sections 11 which are attached to the deepest point have a cylindrical shaft 12 or 14 * the shafts 12 being less deep into the ground δ than
