Definitions

  • the invention relates to a baffle for tennis training using an inflatable air space.
  • Such a baffle is known from DE-A-2 308 082.
  • a cushioning padding made of elastic foam material is arranged on a rigid wall, which can additionally have an inflatable air space on the back to increase the cushioning.
  • baffle is intended to dampen impinging balls, i.e. that their speed is greatly reduced and that the balls, regardless of whether they are hit hard or soft by the player, bounce back as evenly and weakly as possible.
  • the strong damping is achieved in that the baffle consists only of a foam layer that is relatively soft, is compressed on impact and thus significantly dampens the impact force and allows the ball to spring back only in a straight direction.
  • the present invention is therefore based on the object of creating an impact wall which has a considerably greater resilience without substantial damping and thus comes closer to the conditions in a real game on the field with opponents.
  • the air space forming the impact element consists of a one-piece, low-damping, rectangular plate made of a rubber-coated spacer fabric filled with air under excess pressure of 0.5 to 1.5 bar, the two outer fabric webs of which are perpendicular to it running hollow threads are kept at a constant distance and are connected airtight to each other at the peripheral edge.
  • Such a rubber-coated spacer fabric is known in principle from DE-B 2 148 401 after its manufacture and use for floatable bodies, without special attention being paid to the essential property of an internal resilience.
  • the plate 3 according to the invention made of rubber-coated spacer fabric is suspended above the tennis net 2.
  • the spacer fabric consists of the two fabric webs 5 and 6, which are connected to one another via so-called pile threads 7 and are kept at a constant distance from one another.
  • the fabric webs 5 and 6 are provided on their outside with an airtight rubber coating and glued or vulcanized together at the peripheral edge 8.
  • a filling valve 9 via which the plate 3 can be filled with air by means of an air pump.
  • the pressure which is expediently to be selected is expediently from 0 to 1.5 bar, the desired spring characteristic of the plate 3 being able to be set continuously by means of different internal pressures.
  • the spacer fabric plate 3 is now expediently glued over the entire surface to a rigid rear wall 10, for example a plywood or chipboard.
  • This rear wall 10 is then hung via brackets 11 attached to its upper edge over the stationary wall 1 and can thus be easily removed at any time.
  • the free gap between the upper edge of the plate 3 and the upper edge of the rigid wall 1 is expediently provided with a cover 12 in order to prevent balls from falling into this intermediate space.
  • Practice balls 15 can then be struck in a conventional manner against the plate 3 thus assembled, which has a size of approximately 1.5 by 5 m and which is subjected to an appropriate air pressure.
  • the air-filled spacer fabric plate 3 has a considerably higher resilience than a conventional exercise wall made of rigid material and its properties are very close to the conditions on the field with a real opponent. This significantly improves the desired training options. Since the plate 3 is also very weatherproof, it can also be left outdoors when it rains and practically only needs to be removed after the end of the outdoor season.
