Definitions

  • the invention relates to a training device for tennis, in particular for the exercise of the ball throw at the serve to support the tennis instructor.
  • the invention specified in claim 1 is based on the problem of creating an exercise device for the ball throw during a tennis serve, which indicates the correct execution of the ball throw by an optical and / or acoustic signal and thus enables support for the tennis instructor.
  • the advantages achieved by the invention are, in particular, that the exerciser, regardless of the tennis instructor, receives information about the correct execution of the ball throw on the tennis serve through the exercise device.
  • the exercise device enables group work or the simultaneous supervision of several practitioners by only one teacher without the quality of the supervision being reduced.
  • the exercise device can increase the intensity of the exercise.
  • the exercise can also be carried out without the constant supervision of a teacher individually.
  • the transmitting and receiving device in one apparatus it is achieved that the energy supply is only necessary on one stand. This simplifies production and increases user friendliness.
  • the use of the exercise device can be expanded and thus the quality of the exercise device can be improved by also giving acoustic and / or optical signals from the exercise device when the ball exceeds a certain height.
  • the practitioner can and should be trained and adjusted to throw the ball at a specific ball height.
  • Stands the transmitting and receiving devices are arranged with a solar cell unit.
  • the exercise device in its basic variant consists of two height-adjustable stands 1 with preferably three-legged feet 2, which are provided with rollers 7 for easier displacement of the stand 1.
  • the practitioner works between the stands 1 set at a sufficient distance.
  • a transmitter 4 for example a light source, is attached to the upper end of one stand 1 and is supplied with energy via an energy source or an energy supply 3.
  • a receiver 5 for example a photocell, which forwards a corresponding signal to an optical and / or acoustic signal transmitter 6 via known connections and circuits if, as in the case described, the light beam passes between transmitter 4 and receiver 5 a thrown ball is interrupted.
  • a plurality of transmitters 4 and receivers 5 can be arranged next to and / or one above the other, which can trigger different optical and / or acoustic signals.
  • a transmitter 8 in the lower third of one stand 1 and a corresponding receiver 9 on the other stand 1 the location of the exercising person can be checked, ie the exercising person has assumed the correct location when throwing the ball.
  • the stands 1 are adjustable in height, preferably telescopically extendable and provided with a length measuring device. This can quickly
  • the exercises device to be adapted to the respective body size of the practitioner and the horizontal adjustment of the transmitter 4 and receiver 5 is easily possible. It is also conceivable for the stands 1 to be designed without feet 2 and to be vertically rotated by 180 ° on a support structure, for example on the hall ceiling, so as to be adjustable in height.
  • the exercise device with three or more stands 1 is particularly suitable for group training.
  • the inner stands 1 each have a transmitter 4 and a receiver 5 opposite each other at the upper end a practitioner works between two stands 1. Depending on the available area and stand 1 of the exercise device, several practitioners can work simultaneously.
  • a transmitting and receiving device 10 is arranged as an apparatus only on a stand 1. Thus, only this stand 1 needs a power supply.
  • the exercise device can also consist of only one stand 1. However, this requires a special reflector, for example on the wall of the tennis hall, for the signals from the transmitter 10.
  • the transmitting and receiving device 10 works on the basis of the light barrier,
  • Ultra-barrier or as a laser device It is also possible for the power supply to be taken over by a battery 3 and / or a solar cell unit 11 installed on the stand 1. In this case, since the exercise device is easy to transport due to the elimination of the cable, it can also be used cheaply in open spaces where the use of solar energy is particularly useful.
  • the control of the exercising person can be further improved by arranging a plurality of transmitting and receiving devices 10 one above the other on the stand 1.
  • the number of switched on transmitting and receiving devices 10 is freely selectable and is determined in practice by the level of the trainee.
  • the exercise device can be set so that a signal tone is given when the thrown ball has reached the desired height, but an additional signal is given when the ball rises further.
