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.
  • hand-operated ball-throwing machines equipped with running wheels are described in the patents US-A-4 086 903 and US-A-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 it difficult and disadvantageous to collect and refill the balls, but it is also disadvantageous that only a limited exercise program can be completed, namely essentially just a so-called "baseline game", whereas practicing the net is practically not practiced can be because the net is almost stationary in front of the ball throwing machine.
  • DE-A-2 456 997 describes a ten training system in which, in addition to a stationary game net and a ball throwing machine, a ball catch device with a catch net or the like is also provided, so that there is no need to manually collect the balls.
  • a very similar tennis sports training facility with a fixed net, a ball throwing machine and a ball collecting and conveying device with a carrier belt is known from DE-A-2 643 790. Nevertheless, even with these known systems, only a one-sided training program is possible. The same also applies to the training device described in DE-B-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.
  • GB-A-403 184 discloses a portable net frame in which heavy castors also serve as a weight for the upright structure of the net frame in order to fix the manually movable net frame firmly to the installation site. Furthermore, rubber pads are provided at the opposite ends of spar-like rods, which form the basic construction of the frame, in order to additionally increase the friction. It is accordingly only thought in this known device to facilitate transport between the parking space and the installation site. Once set up, however, this well-known network device remains stationary. This is also the case with the game net device according to US-A-4 008 317, in which hollow cylindrical housings are provided as side posts for tensioning the game net and are provided on their underside with feet and with foldable wheels.
  • the wheels are folded up and the system can therefore be regarded as stationary.
  • US-A-4 082 271 describes a device to be set up on a tennis court, on which a conventional stationary game net is provided, at any place, with a live net for throwing back the hit balls. This rebound device thus replaces the otherwise usual ball throwing machines.
  • a similar exercise device is also disclosed, which essentially consists of a plate against which the balls are to be struck, and in the lower area of which, immediately in front of the plate, a game net is provided, the Balls above this net are played against the plate.
  • a safety net is provided above the plate. Again, only the entire facility can be manually moved to the desired location and the facility will be installed there in a stationary manner.
  • US-A-4116436 describes an additional device for a tennis court, namely a device for collecting tennis balls on a tennis court, wherein pairs of link rods are provided and the balls are taken from the link rods to the desired location.
  • guides for the articulated rods and side chain drive devices are provided in the side area of the tennis court.
  • DE-B-2 651 835 further discloses another additional tennis device in the form of a movable hand-held device for collecting tennis balls, with guide rails projecting obliquely forward and outward, which guide the balls towards the center of the device, to a collecting and transport device.
  • a collecting container for the balls is provided in this hand-held device, which container receives the balls from the transport device.
  • US-A-4 108432 describes a ball collecting and ejecting system which has a floor recess provided behind a stationary game net for collecting the tennis balls.
  • a motor drive is assigned to the game net frame and the game net frame with the help of the motor drive between a rear position, in the area of the ball throwing machine and the ball catching device, and a front position, in the area of the player , is arranged movable in the direction perpendicular to the network plane.
  • the game network with its frame can thus be moved by motor towards the player or away from it towards the ball-throwing machine in order to select a specific type of game, e.g. B. 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 game net frame can, for example, run on rollers in rails which are embedded in the floor and thus guide the rollers or the game net frame.
  • 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 network plane. 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 downward in an approximately vertical position when the game net frame is returned to the ball throwing machine, so that it sweeps just above the ground and thus takes all the balls between it and the ball throwing machine.
  • 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.
  • the ball busbar can be pivoted, for example, with the aid of a linkage, manual operation being conceivable, for example.
  • a Bowden cable is provided for pivoting the ball busbar, which is connected to an actuating lever pivotably mounted on the game frame.
  • the actuating lever is assigned a pawl which is movably arranged on the game net frame for at least the position of the actuating lever which corresponds to the pivoted-up position of the ball busbar. This pawl therefore absorbs the load due to gravity on the pivoted-up ball busbar.
  • stationary control cams are arranged in the reversal points of the network frame, on which the actuating lever runs.
  • the actuating lever can z. B. carry a 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 jack then runs, for example when the game net frame is moved towards the player, against the stop and is held back by it, while the lateral support of the game net frame and the actuating lever move a little further to the reversal point, so that the actuating lever is released from the pawl and through the control curve into the other pivot position can be controlled, ie in that position that corresponds to the collecting position of the ball busbar. In this position the operating lever is then z. B. simply held by the pulling mass of the ball busbar.
  • 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 carry out a cycle ⁇ Collect ball '' by automatically moving first towards the player (with the ball busbar folded up) and after automatically switching 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 result is now, in connection with the collecting activity of the game net frame, d. H. the associated pivotable ball busbar, furthermore the particularly advantageous possibility of feeding the balls back to the ball throwing machine completely automatically, d. H. to avoid manual filling.
  • the ball throwing machine can then be assigned a ball conveyor, for example with bowl-like or fork-like carriers for the balls attached to a driven endless chain or the like, the lower receiving point of which is provided in the area of a floor recess which is connected to the game net frame in its rear, the Ball throwing machine connects closer 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 play net frame has a frame for the play net arranged on the side support and the side support is provided with rails which project outwards and backwards and carry the reels.
  • the frame is pivotally mounted about a vertical axis on the carrier. As a result, the frame with the play net can simply be pivoted into a lateral parking position.
  • a play net frame 1 which can be moved over the playground is provided, to which a conventional play net 2 is fastened with a net band 3 with the aid of tendons 4.
  • the game net frame 1 consists of a frame 5 which is fastened to a side support 6 so as to be pivotable about a vertical axis 7 (FIG. 2).
  • the frame 5 with the game net 2 can, for example for cleaning purposes, be pivoted backward from its normal operating position by approximately 45 ° to 60 °, as can be seen from FIG. 2, cf. Arrow A.
  • the pivot mounting of the frame 5 on the carrier 6 can be done in any known manner, for. B.
