Definitions

  • the invention relates to a tennis training system with a game net attached to a frame and a ball catcher and a ball throwing machine behind the game net.
  • Ball throwing machine is arranged on one side of a training area and throws balls at different speeds and in different directions over a net, these balls being intended to be played back by an opposing player over the net.
  • the ball throwing machine can, for example, be electrically controlled in such a way that it throws the balls once more to the left or right or more in the center, less sharply or sharply, depending on the exercise program of the player.
  • the net is firmly attached to a stationary rack, and after the entire supply of balls has been ejected, these balls are collected and filled into the ball throwing machine.
  • manually operated, wheeled ball throwing machines are described in U.S.
  • Patents 4,086,903 and 3,610,223 these ball throwing machines are set up at the desired location on a tennis court and the balls are filled into them manually. Not only is collecting and refilling the balls tedious and disadvantageous, but it is above all disadvantageous that only a limited exercise program can be completed, namely essentially only a so-called "baseline game", whereas the game on the net is practically not practiced can be because the net is almost stationary in front of the ball throwing machine.
  • DE-OS 2 456 997 describes a tennis training facility in which, in addition to a stationary game network and a ball throwing machine or a ball catcher with a catch net or the like. is provided so that the manual collection of the balls is eliminated. Nevertheless, only a one-sided training program is possible here. The same also applies to the training device described in DE-AS 2 638 037, in which a fixed game net and also a fixed exercise net above it and a safety net in front of the game net are provided, to which a ball outlet is connected.
  • the game network can thus be moved with its frame by a motor towards the player or away from it towards the ball-throwing machine in order to select a specific type of game, e.g. to practice the baseline game or the game on the net.
  • the game network can simply be brought into a position such that extremely effective training, realistically adapted to a real tennis game with an opponent, is possible.
  • the play net frame can, for example, run on rollers in rails which are embedded in the floor and thus guide the rollers or the play net frame. But since it should be aimed at, the bottom of the exercise To make the place completely flat, it is preferred that the movable play net frame is guided in at least one guide arranged in the side area of the system and extending perpendicular to the plane of the net. It is sufficient if there is a guide on only one side of the net frame, and it is advantageous if the play net frame is supported on the ground by at least one wheel in the cantilevered area facing away from the guide provided in the side area of the system.
  • a guide channel is provided as a guide in a lateral boundary wall, in which a lateral support of the game net frame is guided by means of rollers.
  • the game net with its frame can be moved back and forth between the player and the ball throwing machine on the training area, there is the particularly advantageous possibility of using this game net or its frame for collecting the balls played on the practice area, to use.
  • the lower edge of the game net or game net frame should preferably run at a distance greater than the diameter of a tennis ball above the floor of the facility so that it can be moved over any tennis balls lying on the floor, and now when the net frame is moved back to Ball throwing machine to sweep or collect the balls in the manner of a sweeping system can advantageously be attached to the underside of the game net frame, a ball busbar extending essentially over the entire width of the game, net or the system pivotable about a pivot axis parallel to its horizontal longitudinal axis .
  • This ball busbar is pivoted downwards in an approximately vertical position when the game net frame is moved back to the ball throwing machine, so that it sweeps just above the floor and thus all between it and the ball throwing balls.
  • this ball collecting machine is pivoted up into an approximately horizontal position so that it can be moved over the balls lying on the court.
  • stationary control cams are arranged in the reversal points of the network frame, on which the actuating lever runs.
  • the operating lever can e.g. carry a three rotatably mounted roller with which it runs on the control cams.
  • a stop for the pawl for releasing the actuating lever is provided in the area of at least one control cam.
  • the pawl then runs against the stop, for example when the game net frame is moved towards the player, and is held back by this, while the side support of the game net frame and the actuating lever still move a little up to Move the reversal point further so that the actuating lever is released from the pawl and can be controlled by the control cam in the other pivoting position, ie in the position which corresponds to the collecting position of the ball busbar. In this position, the actuating lever is then simply held, for example, simply by the mass of the ball busbar pulling downwards.
  • a chain or cable pull is preferably provided to drive the game net frame, which is firmly connected to the game net frame and is driven by an electric motor with a switchable direction of rotation.
  • Such a motor drive is particularly preferred in terms of its control options and also the simple power transmission, the electric motor being able to be arranged in a stationary manner.
  • a limit switch for automatically switching off the electric motor is provided in the area of the reversal point of the game net frame closer to the ball throwing machine and a switch for automatically switching the direction of rotation of the electric motor in the area of the reversal point of the game net frame further away from the ball throwing machine .
  • the net frame has a preferred position in the area near the ball throwing machine, which corresponds to the position for the baseline game, and the net frame can also independently carry out a "collect ball" cycle by first automatically moving towards the player (with the ball busbar folded up) and after automatically switching over to the end position is again moved towards the ball throwing machine (this time with the ball busbar pivoted downwards).
  • a manual control for the electric motor and thus the game net frame can also be provided (in order to bring the game net frame into a certain position between the player and the ball throwing machine as desired and to stop in this position).
  • the ball throwing machine can also advantageously be arranged to be adjustable in height or inclination. It is possible to automatically adjust the ball throwing machine as a function of the position of the net frame, for example with the aid of electrical position switches which are provided in the area of the guide for the net frame, or with the aid of a common control device.
  • a conventional, well-known ball throwing machine can be used in the tennis training system according to the invention.
  • the ball throwing machine can then be a ball conveyor, for example with or the like on a driven endless chain.
  • attached bowl-like or fork-like drivers for the balls, assigned, the lower receiving point is provided in the region of a floor recess which connects to the game net frame in its rear, the ball throwing machine reverse position.
  • a vibrator can also be arranged in the bottom recess, which is provided below the bottom surface of the bottom recess and vibrates the bottom surface in this area near the deepest point, the ball collecting point. This allows the balls to be safely brought into the ball conveyor and filled into the ball throwing machine.
  • the game net frame has a frame for the game net arranged on the side support and the side support with the roles protruding forward and backward rails is provided.
  • the frame is pivotally mounted on the carrier about a vertical axis. As a result, the frame with the play net can simply be pivoted into a lateral parking position.
