Definitions

  • the present invention relates to a new coating composition for tennis, squash or badminton rackets, which is capable of improving the ball guidance by the racket.
  • Strings with string covering e.g. Tennis, squash or badminton rackets, hereinafter referred to as "tennis rackets" are usually strung with longitudinal and cross strings which cross at right angles, the material of the string, its elasticity and the tension being essential for the playing characteristics .
  • the gut strings originally used are increasingly being replaced by plastic strings, especially in popular sports, since they are much easier and cheaper to manufacture.
  • the plastic string has a comparatively much smoother surface, so that the ball guidance is less good.
  • strikes which are struck with a spinning or twisting lead to sideways pressure on the main strings, so that they move out of position, which changes the suspension properties of the stringing and the ball guidance is no longer precise is. Since the strings once shifted are rarely compensated for by corresponding counterforces in later beats, the spier can only re-establish the stringing after the end of the change of beats and thus restore the ideal beating conditions.
  • the strings of the racket are coated thinly with a solution of a recent or fossil resin, in particular in the central area which is particularly important for the ball guidance, and the solvent evaporates.
  • the remaining, very thin film causes the strings to adhere better to one another, so that they are not easily moved out of position by transverse forces, ie they do not slip on a ball with spinning.
  • the contact between the string and the ball to be struck is strengthened, so that the ball is guided better and thus allows a more precise striking technique.
  • Rosin which is obtained from coniferous wood as a distillation residue of the balm and is used as a resin and has been used in technology for the production of lacquers, paints, printing inks, soaps, adhesives, as a flux during soldering, for coating violin bows etc. becomes.
  • Colophonium is soluble in many organic solvents. All readily volatile solvents are suitable as solvents for the purpose according to the invention. Since the evaporating solvent could be partially inhaled when the clubs were sprayed, the solvent should be as health-compatible as possible. Ethanol, isopropanol, acetone, methyl ethyl ketone and ethyl acetate are therefore particularly preferred.
  • rosin other recent or fossil resins can be used, which are similar to rosin in properties such as hardness, melting and softening properties, and solubility.
  • Canada balsam, Peru balsam or Japanese lacquer are examples of tree resins, shellac as the most important resin of animal origin, and montane resin or montan wax as fossil resins.
  • the resins used are used as 1-50%, preferably 2-20%, solution (g / ml), with about 2-5% solutions being preferred for spraying.
  • Concentrated solutions have the disadvantage that their viscosity becomes too large and the amount of solution to be applied is too small to be uniform Allow resin to spread over the surface of the string. Concentrations which are too low have the disadvantage that excessive amounts of the solution have to be applied, so that large amounts of solvent are evaporated unnecessarily.
  • the preferred range between about 2 and 5% has proven to be a particularly favorable compromise between the two limit values.
  • the solution according to the invention is preferably applied as a spray, application in a pressure bottle being possible, but for environmental reasons a pump mechanism which is customary in cosmetics and which uses an air jet as the transport medium is preferred.
  • the clubs are thoroughly sprayed once with the spray liquid according to the invention, for which 0.5 to 1 cm 3 of a 4-5% solution are sufficient and later the abrasion of the resin which occurs in the game by spraying with 0.1-0. 5 ml of a solution replaced at the necessary intervals.
  • fumaric acid and / or maleic acid has proven to be particularly advantageous since not only the softening point of the resin is increased, which makes the surface of the coated strings appear drier (less sticky), but also the solutions are more concentrated , e.g. B. up to 50% (g / ml) can be applied.
