Definitions

  • the present invention relates to an improvement to racket frames reinforced by honeycomb.
  • racket frames comprising a honeycomb core - in one or more pieces - surrounded by a metallic envelope, made of synthetic material or of composite material.
  • rackets are currently on the market which consist of two identical metallic shells enclosing a metallic honeycomb ribbon, the whole being assembled by gluing (see Belgian patent n ° 856.598).
  • the improvement according to the invention consists in filling at least one carefully selected cell of said honeycomb with a high density substance.
  • a high density substance By the latter expression is meant a substance whose specific weight is at least 2 kg / dm 3 .
  • a mixture of an organic binder and a zinc powder charge will advantageously be chosen.
  • the filling of the selected cell (s) will take place at the most appropriate stage of the manufacturing of the frame, after deployment of the honeycomb and either before its insertion in a tubular envelope, respectively its coating in the case of a composite manufacturing, either after its installation in one of the above-mentioned half-shells.
