Definitions

  • the invention concerns a device comprising a table tennis robot that serves, collects and returns balls in accordance with the introduction to Claim 1.
  • the main purpose of the present invention is to devise a table tennis robot that gives a training situation that really provides a game.
  • An other objective with the present invention is to devise a table tennis robot that returns varied balls.
  • a further objective with the present invention is to devise a table tennis robot that returns balls from different positions as a response to shots from the player.
  • a further objective with the present invention is to devise a table tennis robot that returns balls after a serve from the player, or after a player has pressed an impulse switch.
  • a further objective with the present invention is to devise a table tennis robot that returns balls only after the player has hit the other side of the table.
  • a further objective with the present invention is to devise a table tennis robot that is almost silent.
  • a further objective with the present invention is to devise a table tennis robot that does not return more balls than the number the player returns.

  • fig. 6 shows a side perspective of a table tennis table as a second design of the present invention
  • fig. 7 shows a front perspective of the design in fig. 6.
  • Each of the pendulum frames 8 is connected to its own microswitch 5, located on the top side of the axis of movement around mounting point 7, where the microswitches are mounted on the top cover of the collection unit.
  • the plate 1 When a player hits a ball, the plate 1 will dampen the ball and control its bounce. The ball then travels horizontally towards the damping plate 2. The force of the ball starts the pendulum plate 8 to move around the axis of its mount 7.
  • the microswitch 5 is activated by this movement through an adjustable scr «ew 6.
  • the microswitch 5 is connected to an automatic launcher, with feed, generally-termed 26 (Figs. 4-5) and a per se known firing mechanism. There are openings 17 between the pendulum frames 8 where the firing mechanism has space to shoot balls towards the player.
  • the firing unit is fitted on tracks 9 to provide a means of regulating the lateral direction.
  • This firing robot provides a controlled return of the next ball.
  • Below the receiver plate 2 there is an open tube 4, which has a fall towards each side with its highest point in the middle.
  • photoelectric cells 5 can be used to register when the balls come and where they hit. This is a particular advantage with slow balls (slice shots), as the impetus of the ball will be too slow to make the pendulum frames move.
  • the photoelectric cells 5 can be positioned just above the surface of the table.
  • Fig. 3 shows the collection system in accordance with the present invention.
  • Open tube 4 is connected at its end to tube 21, that the balls are sucked into.
  • Tube 21 has an internal diameter which is fairly close to the outer diameters of the balls, this ensures good suction.
  • Tube 21 is connected at its other end to the suction chamber 16, which contains a motor 27, a fan 29 and a cap 28, all of known design.
  • the motor 27 for the fan 29 can be regulated and used to control the speed of the game.
  • a coiled spring 23 is located inside the suction chamber 16 where tube 21 ends.
  • Coiled spring 23 guides the balls through the chamber 16 and has a diameter that is a little larger than tube 21.
  • Coiled spring 23 ends in a tube connection 24, that guides the balls to another coiled spring 30.
  • a ball in the space between the chamber 16 and the tube connection 24 will act as a valve until the next ball comes.
  • the balls go into a feed unit 26 through a tube connection 25, that is flexibly connected to chamber 16.
  • the coiled spring 30 and the tube connection 25 mean that the feed unit 26 can be placed in different positions and at different angles.
  • Figs. 4 and 5 show the feed unit 26 in detail.
  • This consists of a restraining spring 33, that keeps balls in place until an impulse on a microswitch 5 gives the message that a ball is to be fired.
  • This impulse goes to a propulsion mechanism 31, and works by a spring piston, or similar, 32 striking the ball with enough force to release it from the. restraining spring 33, so that the ball is fired.
  • the propulsion mechanism 31 can be an electromagnet (piston or motor), air cylinder, or be another Known system tiiat is not part of the invention. After the propulsion mechanism 31, a non-illustrated firing mechanism of known design can fire the balls towards the player.
  • Fig. 6 shows a simple playing machine that is designed along the same damping plate principle as shown in Fig. 1.
  • the damping plate 1 is identical, and the guide plate 15 is also used.
  • Damping plate 2 has no fixing frame, but is attached to mount 12 which also serves the purpose of acting as a frame between the support 14 and the wheels 13.
  • a cover 11 holds the damping plates 2.
  • Fig. 7 where the collection tube 4 has a fall to one side. The player can adjust this fall to the side he/she wishes to get the return balls from.
  • the frame 10 can be fitted to both sides. After the feed mechanism, the ball goes through a tube connection 24 to a chute 6 and rolls towards the player who gets enough time to prepare a shot. Chute 6 can be adjusted in height as well as sideways.
  • This design is particularly useful to train beginners in hitting straight returns. This is done by allowing balls from chute 6 be hit to plate 1, and damped between plates 1 and 2 and fall down into the open tube 4. Then balls will roll along one side, be sucked up through the riser tube 21 by the motor 27 and the fan 29.
  • the suction chamber 16 can be designed as in Fig. 3, but a simpler design is preferred. Tube 21 is connected diagonally to chamber 16, in the chamber there are guide springs for the balls. At the bottom of the chamber, there is a tube connection 24 where a ball will hang suspended by the suction from the fan 29. When the next ball comes, this will fall on the ball that is in connection 24, and force this to roll down chute 34, and stop in connection 24 itself.
  • the system has two to three balls in circulation, depending on the tempo that is required.
  • this design has a return tube that can be used when a player wants training in serving. In this case the fan is stopped and there is an opening between tube 4 and the chute 36. This means that the player does not need to pick up balls, but gets them returned to the playing position.

Abstract

L'invention concerne un robot pour tennis de table envoyant une balle à un joueur afin de simuler une situation de jeu réaliste, le dispositif comprenant une unité de tir, une unité de réception et une unité de récupération. Une plaque d'amortissement (1) est située sur la table de ping-pong, sur le côté de la table opposé au joueur. Ladite plaque d'amortissement (1) ralentit et dirige les balles venant du joueur. Un mécanisme de déclenchement assure que le joueur reçoit une balle de retour lorsque celui-ci frappe une balle correctement. Ledit dispositif peut comprendre plus d'une unité de tir auxquelles sont associés des mécanismes de déclenchement, de sorte que les balles de retour proviennent de la même zone que celle vers laquelle le joueur a envoyé la balle.
