Definitions

  • the invention relates to an additional device for training purposes on a tennis net, which is held between side posts on a rope stretched horizontally between them, with vertical additional posts arranged on the side posts of the tennis net, which project above the posts and each carry an additional rope at its free end, which is stretched over the horizontal rope to form at least one ball passage window that can be selected in size and position over the tennis net.
  • the additional rope forms a continuous opening above the tennis net and forms a ball passage opening, which can optionally be divided by vertical strips attached to the additional rope.
  • a ball passage opening which can optionally be divided by vertical strips attached to the additional rope.
  • An actual control of the training result is not possible in case of doubt.
  • the known arrangement of the additional rope does not make it possible to form an asymmetrical flyover area for the ball above the tennis net.
  • the invention has for its object to provide an additional device for training purposes on a tennis net, through which precisely determined, also asymmetrically located flight openings of the ball over the net can be specified.
  • the ball should be prevented from flying over the net if the flight opening is not hit.
  • an additional device of the type mentioned at the outset that at least two, preferably a plurality of additional nets are independently and slidably tensioned on the additional rope, and that the additional rope on the additional posts on both sides is also independently below
  • the height of the rope or the post in inclined positions can be adjusted in height in order to form ball passage windows and / or ball pass areas of different shape and position between the additional nets and / or above the additional rope.
  • the trainer has the possibility of specifying certain ball passage openings over the net for the training tennis player, which after
  • Y ⁇ ri. " w ⁇ aPo " _ Size and location can be adjusted quickly. It is only necessary to move the additional nets on the additional part accordingly. The balls not reached by the trainer, which are not reached by the trainer, are caught by the additional nets, so that a reliable control of the success is possible. Due to the inclinability of the additional rope, where one side of the additional rope can be lower than the height of the tennis net, an asymmetrical flyover area can be formed over the tennis net, in which, for example, the forehand side is partially covered by the additional nets that this area can only be flown over with topspin hit balls, while the backhand area has the normal net height and can be passed with slize hit balls.

  • the additional nets have hooks on their lower edge, which can be hooked onto the tennis net under tension of the additional net.
  • the vertical edges of the additional nets expediently carry a border and at least at the lower end of the border there is a hook in each case in order to tension and fix the edges of the additional nets delimiting the respective flight window formed and by the border the flight window well marked.
  • the border may be contrasted in color with the additional network.
  • the additional rope is designed as a flat band.
  • the rings carrying the additional nets do not slip on such a band, in particular when the additional rope is stretched in a strong inclined position.
  • the additional rope can be an inextensible band which is stretched between the additional posts with a tensioning device.
  • the additional rope or band can also be elastic to use a double hook according to a further embodiment of the invention, which can be hooked on the one hand on the additional rope and on the other hand at one point on the tennis net or the rope to the additional rope in a flat V-shaped position hold.
  • a flyover area can thus be formed above the tennis net, which has the normal height of the tennis net in the middle, but is increased on the sides by the additional nets, so that lateral balls can only be brought over the net in topspin.
