Definitions

  • the invention relates to a racket for a ball game, in particular a tennis racket with a frame consisting of racket head and shaft and with an axially screwable grip sleeve.
  • a tennis racket of the type mentioned is. B. known from German utility model 77 17 463.
  • the shaft of this racket has longitudinal grooves along its entire circumference.
  • the grip sleeve has a bore with longitudinal grooves of the same shape and can be plugged onto the shaft.
  • the longitudinal grooves of the shaft and the grip sleeve form a positive toothing. After pulling off the grip sleeve from the shaft, the grip sleeve can be rotated according to the pitch of the toothing and put on again.
  • the grip sleeve is fastened to the shaft with the aid of a screw which lies against the end of the grip sleeve and engages in the end of the shaft.
  • a tennis squash or badminton racket is known from Swiss patent specification 470 891, which consists of a frame part having a shaft and a separate grip part.
  • the shaft has a conical end and the grip part or the grip sleeve is correspondingly conical and can be plugged onto the end of the shaft.
  • the grip part is held there by gluing, screwing or in some other way.
  • the purpose of this construction is to keep rackets with different grip thickness or grip weight as simple as possible.
  • An adjustment of the handle part relative to the shaft is not intended, especially since the shaft and the handle part z. B. to be permanently connected by gluing.
  • the invention aims to create a tennis and / or squash racket or the like, which is matched to the very special, individual anatomical conditions of a player. Just as the fingerprint is unique for each person, this also applies to the bones of the wrist, elbow, arm tendons and muscles, etc. For this reason, it is also fundamentally wrong if a tennis player uses the same racket as a Games winner or the Winner of an international tennis tournament. On the contrary, it may well be correct only in terms of playing style as health under fertigisct% L reasons because of anatomical differences when a tennis racket is designed so that it meets the anatomical circumstances of the player.
  • the invention is therefore based on the object of creating an anatomically correct racket which is also economically producible and is functionally able to cope with the very high loads which occur during play.
  • the invention provides that the grip sleeve and the shaft are freely rotatable about their axis and can be both rigidly connected and detached in a purely positive-locking manner in arbitrarily different angular or rotational positions, for which purpose the shaft has a cone and the grip sleeve a conical one Have a bore and a bolt with a thread on the shaft and a bore for receiving the bolt are arranged in the grip sleeve.
  • a further development of the invention further provides that a grip piece which can be rotated relative to the grip sleeve is provided with an internal thread, that this grip piece is arranged at the end of the grip and is supported in the direction of the racket axis on the grip sleeve.
  • the tightening and loosening of the fastening can be done by using the handle without tools and can be accomplished particularly easily and for a short time.
  • a tennis racket 1 consists of a frame 2 with a grip sleeve 3, a shaft 4 and a racket head 5 with strings 6.
  • the grip sleeve 3 can be rotated continuously relative to the racket head 5 about the longitudinal axis 7 of the racket and can be fastened in any position. With regard to their angular or rotational position and thus to absorb the torsional or torsional forces, the grip sleeve 3 and the racket head 5 are connected to one another in a purely frictional manner.
  • conical or frustoconical surfaces 8 and 9 are provided between the grip sleeve 3 and the club head 5.
  • a cone 10 on the shaft 4 and a conical bore 11 or an inner cone 11 on the grip sleeve 3 serve to form these surfaces.
  • the grip sleeve 3 overlaps with its inner cone 11 the cone 10 on the shaft 4 and receives the threaded bolt 12 with a bore 15. With the aid of the handle 13, which can be screwed onto the threaded bolt 12 in the manner of a nut, the grip sleeve 3 is fastened to the shaft 4, this being possible in any position after turning the grip sleeve 3 and shaft 4.
  • the grip piece 13 is arranged at the grip end 16 and is supported on the longitudinal axis 7 of the stick in the direction of the latter.
  • the handle 13 is profiled on its circumference.
  • FIG. 3 shows a modified embodiment, according to which a handle 18 is also provided, which also has an internal thread 17 for the threaded bolt 12 and which engages with a sleeve-shaped part 19 in the bore 15 of the handle sleeve 3.
  • the sleeve-shaped part 19 has an annular groove 20, into which at least one holding element 21 connected to the grip sleeve 3 extends.
  • the holding element 21 is, for example, screwed through the wall 22 of the grip sleeve 3 and serves as an abutment when turning or loosening and tightening the grip piece 18.
  • the parts 20 and 21 form a link guide.
  • the conical parts and the threaded bolts are dimensioned according to the forces that occur.
  • a plastic is expediently used as the material, different materials for the cone 10 and the surface of the conical bore 11 being advantageous because of the coefficients of friction.
