Definitions

  • This invention relates to strung racquets such as those used for playing tennis, squash racquets, raquet ball and badminton, and more particularly it relates to a device for selective tensioning of the strings of those racquets and racquets fitted with such a device.
  • the tension of the strings of a racquet is of importance to a skilled player of the games of tennis, squash, etc and frequently involves a matter of personnal choice.
  • degrees of tension are normally specified by the player and must be complied with in production, as once strung it is difficult and/or inconvenient to re-adjust the tension.
  • it is common for the tension to change during use of the racquet thus entailing similar difficulty and/or inconvenience.
  • a tensioning device for a racquet provided with a head having a plurality of string holes through which one or more strings are threaded and drawn tight
  • said tensioninq device comprising a threaded socket for fixing within or on said racquet head between two of said string holes, a bolt threaddeably engagable with said socket, a tool-engaging formation on said bolt for effecting advancement along said socket, and a cap freely rotable upon the other end of said bolt for engagement with a string extending between said two string holes so that with said advancement of the bolt an increase in tension of said string is effected.
  • the threaded socket is mounted with a base adapted to abut the outer periphery of the head, to said base being provided with apertures to respectively coincide with said two string holes which facilitate the string of the racquet being passed through the apertures and across the base.
  • the base is elongate to extend along a portion of the periphery of the racquet head and mounts a plurality of said threaded sockets for location between other string holes, each socket having said apertures adjacent thereto.
  • the string tensioning device of the invention is intended for tension adjustment by the application of additional strain upon a single pair of strings.
  • the device may be provided in a form (as shown in Figure 3) wherein a plurality of devices are provided upon a common frame.
  • Fig. 1 depicts a strung racquet 4 having a handle 5 connected through a shaft 6 and a yoke 7 to a head 8.
  • the head 8 has string holes 9 arranged around its periphery through which a gut, or other, string 10 or strings is threaded and drawn tight to a predetermined tension.
  • the racquet 4 is fitted with a tensioning device comprising an internally threaded socket 13 mounted with a base 14 adapted to abut the outer periphery of the head 8 when socket 13 is accommodated within a hole in the head between two of string holes 9.
  • a tensioning device comprising an internally threaded socket 13 mounted with a base 14 adapted to abut the outer periphery of the head 8 when socket 13 is accommodated within a hole in the head between two of string holes 9.
  • the base 14 extends to cover the two string holes 9 adjacent the hole in head 8 and is provided with apertures which coincide with the string holes to facilitate the string being passed through the apertures and across base 14.
  • a bolt 15 is threadably engaged within the sleeve and carries a loosely fitted cap 16 which is freely rotatable with respect to the bolt 15.
  • the cap 16 is dome shaped with an inturned peripheral edge 20 for capturing the enlarged head 21 of the bolt 15.
  • the cap 16 is provided with a transverse slot 19 along which a string 10A passes before returning through the frame head 8 to constitute a further string 10B in the racquet 4.
  • the end 17 of the bolt 15 may be provided with any tool-engaging formation, and preferably has an internal hexagonal recess to accept an Allen key tool.
  • the embodiment illustrated in Figure 3 includes an elongated base 14A to extend along a portion of the peiphery of the racquet head and which mounts three identical threaded sockets 13A which are positioned between a respective pair of apertures 9A provided in the base 14A. With the head 8 of a racquet bored to accept the three sockets 13A, the device may be attached within the yoke 7 of the racquet 4 with adjustment provided in respect of three pairs of central strings of the racquet 4.
  • socket 13 and base 14 may be replaced by a nut fitted into a hole in the head of the racquet.
