Definitions

  • the present invention relates to a height adjusting device for use in string pulling block of string machine that may improve the stringing quality and facilitate the height adjustment of the string pulling block.
  • Tennis and badminton are both a healthy and intellectual sport.
  • a racket and strings with a precise pound number are both an indispensable winning factor in a tennis or badminton game.
  • the string method of racket also influences the service lives of racket and strings.
  • a prior art string machine comprises a base a, a holder b and a string pulling block c (as shown in FIG. 1 ), wherein the holder b is axially connected to the top of the base a for 360 degreed rotation and positioning, and the string pulling block c includes a string puller c1 and a lever c2 both arranged thereon.
  • a rod member 10 for combining with the string pulling block c is coupled onto the upper side of the base a (as illustrated in FIG. 2 ) and includes racks 101 arranged thereon, such that the string pulling block c may move along the racks 11. In other words, the string pulling block c may move relative to the rod member 10.
  • the frame d is supported by the holder b, and the string e is fixed between the string puller c1 of the string pulling block c and the frame d (as shown in FIG. 2 ), thereafter, the pound number of the string is set, and by rotating the lever c2, the set pound number of the string is achieved, thereby assembling the longitudinal and lateral strings e of the frame d in turns.
  • the present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
  • the primary object of the present invention is to provide a height adjusting device for use in string pulling block of string machine that may protect strings and a frame from harm.
  • Another object of the present invention is to provide a height adjusting device for use in string pulling block of string machine that may avoid the contact of the frame and a string puller during the rotation of the frame.
  • a height adjusting device for use in string pulling block of string machine comprising comprises a rod member and a coupling seat, and the string machine including a base, a holder and a string pulling block (its structure is the same as above-mentioned description, therefore further remarks would be omitted), wherein the rod member is constructed in the form of an elongated plate for combining with the string pulling block and includes racks arranged thereon such that the string pulling block may move along the racks, and includes a tilted sliding member, cross section of which is in the shape of an inverted U, coupled at one end thereof and having two biasing tabs disposed at the cater-cornered sides thereof the titled coupling seat is mounted on the upper side of the base of the stringing machine and includes a rail arranged thereon, by using the sliding member, the rod member is axially connected with the rail for obliquely moving along the rail upward and downward, thus adjusting the height of the string pulling block, in addition, the coup
  • a frame is supported by the holder, and a string is fixed between a string puller of the string pulling block and the frame.
  • the pound number of the string is set, in the meantime, since the string is in an extension state, the sliding member of the rod member obliquely moves upward by way of the string pulling block, thereby the string inserted between the frame and the string puller is almost in a horizontal state, and one of the biasing tabs abuts against the micro-adjustable screw of the coupling seat, then the micro-adjustable screw is rotated for having a micro adjustment to let the string become horizontal. Finally, by rotating a lever, the set pound number of the string is obtained, thus assembling the longitudinal and lateral strings e of the frame d in turns.
  • the sliding member obliquely and downwardly moves toward another biasing tab which is biased against the adjusting screw of the coupling seat.
  • the adjusting screw is rotated, simultaneously, the heights of the sliding member, the rod member and the string pulling block are descended without causing the grip to contact with the string puller, facilitating rotation in different directions.
  • a height adjusting device for use in string pulling block of string machine in accordance with the present invention comprises a rod member 1 and a coupling seat 2, and the string machine including a base a, a holder b and a string pulling block c (its structure is the same as above-mentioned description, therefore further remarks would be omitted), wherein the rod member 1 (as shown in FIGS.
  • the coupling seat 2 including two side plates 22 for corresponding to each other is used to receive the rail 21 therein such that the sliding member 12 may be limited to slide on the rail 21 between the two sides 22 of the sliding member 12, one of the side plates 22 contains a micro-adjustable screw 23 screwed therein, and another of the side plates 22 involves an adjusting screw 24 screwed therein, and the micro-adjustable screw 23 and the adjusting screw 24 are in response to the biasing tabs 121 of the sliding member 12 individually.
  • a frame d is supported on the holder b, and a string e is fixed between a string puller c 1 of the string pulling block c and the frame d (as shown in FIG. 6 ).
  • the pound number of the string is set, in the meantime, since the string e is in an extension state, the sliding member 12 of the rod member 1 obliquely moves upward by way of the string pulling block c, thereby the string e inserted between the frame d and the string puller c1 is almost in a horizontal state, and one of the biasing tabs 121 abuts against the micro-adjustable screw 23 of the coupling seat 2, then the micro-adjustable screw 23 is rotated for having a micro adjustment to let the string e become horizontal. Finally, by rotating a lever c2, the set pound number of the string e is obtained, thus assembling the longitudinal and lateral strings of the frame d in turns.
  • the sliding member 12 obliquely and downwardly moves toward another biasing tab 121 which is biased against the adjusting screw 24 of the coupling seat 2 (as shown in FIG. 8 ).
  • the adjusting screw 24 is rotated, simultaneously, the heights of the sliding member 12, the rod member 1 and the string pulling block c are descended without causing the grip d1 to contact with the string puller c1 facilitating rotation in different directions.
  • the micro adjustments of the heights of the sliding member 12, the rod member 1 and the string pulling block c may be achieved by means of an electronic controlling system, causing a precise position.
