Definitions

  • the present invention refers to an anti-vibration handle for rackets for tennis, squash and similar sports, which is completely insulated from the frame, and a related method of production.
  • Another proposed system consists in using a hollow detachable handle, inside of which an expensive complex fastening element is inserted, made of a light alloy, incorporating rubber insulating elements.
  • US-A-4 660 832 describes an anti-shock and anti-vibration handle for tennis rackets and the like, wherein between the shank and the external shell a tubular shock absorber element is foreseen, substantially extending throughout the length of the handle. According to another form of realization, in the place of the tubular element, a plurality of parallel longitudinal strips is foreseen, also extending throughout the length of the handle. According to one of the embodiments, said external shell made of aluminum, plastics or the like, is in two halves.
  • the aim of this invention is to provide a racket for tennis or similar sports, with very good insulation of the handle from the frame, and which is of low cost, without alterations in its balancing or weight.
  • the external dimension of the shank are reduced by the thickness corresponding to the shock absorbing elements which are positioned on it.
  • the handle is made separately in two half shells, for example by molding expanded polyurethane, instead of being injected onto the shank of the frame.
  • the link between the half-shells and the inner shank which is carried out in the form of longitudinal transverse discontinuous lines, makes the same half-shells a system which does not resonate with the vibration propagating along the inner shank.
  • reference numeral 1 indicates a monolith frame (shown only in part) of a racket for tennis or similar sports, obtained for example by molding suitable materials, such as glass fibre, carbon and suchlike, impregnated with suitable resins.
  • shank 2 is shown as being of circular section, with two inner cavities 3, 4, separated from each other by a bulkhead 5. It is obvious, however, that the shank 2 can have any type of section, and possibly also only one inner cavity, since this does not have any effect on the aims of the invention.
  • the invention requires a reduction of the outer dimensions of the section of the shank 2 with respect to those of a traditional racket with the same outer dimensions of the handle, for the insertion of the shock absorbing elements, which will now be described.
  • a plurality of shock absorbing elements 6 are positioned around the shank 2, spaced out from each other, for the purpose of insulating the handle from the frame 1 completely.
  • the shock absorbing or insulating elements 6 are preferably strips of elastomer, gel of similar soft materials, which are wound round and glued onto the shank 2, as can be seen in diagrammatic form in figure 3.
  • One or both of the faces of the strips 6 may possibly be provided with notches 7, for the adhesive to hold better, between the strips and the shank and possibly between the strips and the outer handle, as will be dealt with below.
  • the handle is made of two half shells 8, 9, preferably equal to each other, realized separately, by molding expanded polyurethane, for example.
  • Each half shell 8, 9 has inner longitudinal cavity 10 which reproduces the outer profile of the shank 2, a semi-circular cavity in the shown example, in such a way that the coupling of the two half shells 8, 9 determines a cavity housing the shank 2, onto which the shock absorbing elements 6 have previously been positioned.
  • glue or adhesive material may be foreseen in these zones, in order to make the shock absorbing elements hold better.
  • the coupling of the two half shells 8, 9 takes place by means of a certain pressure, so as to compress the elastomer strips 6 slightly and cause the half shells themselves to adhere, after putting glue or two-sided adhesive material between the matching edges 11 of the half shells.
  • a handle is thus obtained which is completly insulated from the inner shank 2 making up part of the racket frame 1, by means of the strips of elastomer 6, thus eliminating all the problems described above.
  • FIG 4 and 5 a modified embodiment of the shock absorbing or insulating element is shown, in the form of a closed ring 6', which is fitted onto the shank 2.
  • This longitudinal discontinuous link between the shank 2 and the half shells 8, 9 prevents vibrations from propagating from the frame 1 to the end of the handle, where the racket is normally seized.
