Definitions

  • the invention relates to a racket for sports with a hollow frame with an edge and a handle, the edge having openings through which a string runs which forms the striking face, the handle having the shape of a Y, which on the The ends of both arms are connected to the edge and thus delimit a bridge part of the edge which extends between the ends of the arms, the bridge part has a subdivision, and the free ends of the bridge part bear against an insert which reduces the arm strain on a user during play .
  • Such sports rackets are used in games such as tennis, squash and other ball games.
  • Rackets with a divided frame, the edge of which has an interruption into which a resilient insert is inserted are not new. They were developed to increase the optimal hit area, the so-called "sweet spot", on the strings of the racket strung and to reduce the momentum, which is transmitted from the ball over the racket to the player's arm.
  • the split frame and the resilient insert allow the edge of the club head to deform more than would otherwise be possible and absorb some of the impact energy that the player's arm would otherwise feel in the club head. Because of this, poses the divided frame represents progress in the field of racket ball games.
  • Rackets with a divided frame are die-cast and also hollow for weight reasons.
  • the construction of all hitherto manufactured rackets with a divided frame is such that the frame is divided in the center of the bridge part and the arrangement of the sides is such that only the two central openings for the side penetrate the bridge part directly, while the adjacent openings for the string are bent towards the side of the club head. If the strings are not bent towards the sides, the movement of the free ends of the racket edge during the game is too great.
  • both hollow ends of the bridge part are provided with a reinforcing insertion element which limits their movement and the breakage of the racket excludes during use.
  • the insertion element rests elastically on the inner surfaces of the bridge part.
  • the length of the bridge part is preferably so large that at least four or six openings for the string are arranged therein.
  • a strip-shaped element is preferably present, which abuts the bridge part on the side opposite the striking surface and the length of which extends at least over four openings.
  • FIG. 1 there is shown a racket, generally designated by the reference number (8) and tensioned with sides of conventional type, generally designated by the reference number (10) are.
  • the frame of the racket has a Y-shaped handle (12) and a head with a rim (13) which has an interruption in its bridge part, so that two spaced, free ends (17) are created.
  • a reinforcing insertion element (19) is arranged in the cavity of each of the free ends (17) of the bridge part.
  • Each insertion element (19) limits the deformation of the associated free end (17) during the game. Without this feature, the problem of the prior art, namely the breakage of the frame, would continue.
  • the insert which is generally designated by the reference number (20), is oppositely beveled on surfaces (22) which are designed in such a way that the ends (17) laterally protrude from the plane of the edge (13 ) of the racket.
  • a significant change which is now made possible by the present invention, is the extension of the strip element (25) in order to further distribute the load due to the impact of the ball during the game.
  • the strip element (25) has a more limited length, which does not produce a corresponding load distribution.
  • a strip element (24) located on the outside underneath has sleeves (26) molded on in the prior art and in the preferred exemplary embodiment of this invention, which extend from the strip element (24) and secure the insert (20) in the racket.
  • the covering of the racket which is shown in the preferred embodiment, is conventional.
  • the strip element (24) is fixed in position in the racket by the tension of the string sections (10a, 10b, 10c, 10d, 10e and 10f) of the string 10, which extends through and around the edge (13) and is continuous.
  • a shock-absorbing clamp element (32) is placed on the free ends of the sleeves (26).
  • the clip element (32) engages over the strings of the racket and the free ends of the sleeves (26) in order to transmit vibrations during the game due to the impact of a ball by the sleeves (26) and the strip element (24) for the insert (20).
  • the insert (20) (with the exception of the extension of the strip element (25)), the clip element (32) and the strip element (24) with the sleeves (26) are all elements which belong to the prior art.
  • the reinforcing insert member (19) of the preferred embodiment is made of wood, but other suitable materials are apparent.
  • a plastic material with the desired physical properties can also be used.
  • the purpose of the insert (20) is to provide the necessary support to limit the movement of the inner free ends (17) sufficiently to avoid breakage.
  • the most preferred materials are therefore those which both have the necessary mechanical strength and are of comparatively low weight.
