Definitions

  • the present invention relates to a height adjusting device for use in string puller of 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 c 1 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 puller of 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 puller of 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 puller of string pulling block of string machine comprising a base, a frame, a string pulling block and a rod member, wherein the rod member includes racks provided thereon and having a gear meshed on the upper side thereof such that the sting pulling block mounted on the rod member may be meshed with the racks by way of the gear and moved along the racks, the string pulling block at least contains a string puller and a lever disposed thereon.
  • the height adjusting device includes a string pulling block having an upper support provided therein and having a titled slidable mount disposed thereon, includes a lower support mounted on the rod member, having a titled coupling seat affixed thereon and having a string puller connected thereon, and includes a string puller fixed on the upper support, wherein the slidable mount is obliquely connected with the upper support and involves abutting portions formed on two sides thereof; the coupling seat is obliquely coupled with the lower support and involves an inclined rail arranged thereon for axially moving a sliding member therein.
  • the coupling seat further includes two side plates in response to each other secured at two sides thereof for receiving the rail therein and for sliding the slidable mount between the two side plates thereof.
  • one of the side plates includes a micro-adjustable screw screwed thereon, and another of the side plates includes a micro-adjustable screw screwed thereon, the micro-adjustable screw and the adjusting screw are in response to the abutting portions of the slidable mount respectively.
  • a frame is supported on the holder, and a string is fixed between a string puller of the string pulling block and the frame. Thereafter, the pound number of the string is set, in the meantime, since the string is in an extension state, the slidable mount of the upper support obliquely moves upward by means 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 abutting portions is biased 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, and since the micro-adjustable screw abuts against the abutting portion, during the string pulling process, the string will be kept in a horizontal state. Finally, by rotating the lever, the gear urges the string pulling block to cause an upper movement on the rack, hence the set pound number of the string is obtained, assembling the longitudinal and lateral strings of the frame in turns.
  • the slidable mount obliquely and downwardly moves toward another abutting portion which is biased against the adjusting screw of the coupling seat.
  • the adjusting screw is rotated, simultaneously, the heights of the slidable mount, upper support and the string puller 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 puller of string pulling block of string machine in accordance with the present invention comprises a base a, a frame b, a string pulling block c and a rod member f, wherein the rod member f includes racks f1 provided thereon and having a gear f2 meshed on the upper side thereof such that the sting pulling block c mounted on the rod member f may be meshed with the racks f1 by way of the gear f2 and moved along the racks f1, the string pulling block c at least contains a string puller c1 and a lever c2 disposed thereon (as illustrated in FIG. 6 ).
  • the height adjusting device includes a string pulling block c having an upper support c3 provided therein and having a titled slidable mount 1 disposed thereon (as shown in FIG. 6 ), includes a lower support c4 mounted on the rod member f1, having a titled coupling seat 2 affixed thereon and having a string puller c2 connected thereon, and includes a string puller c1 fixed on the upper support c3, wherein the slidable mount 1 is obliquely connected with the upper support c3 and involves abutting portions 11 formed on two sides thereof; the coupling seat 2 (as shown in FIGS.
  • the coupling seat 2 further includes two side plates 22 in response to each other secured at two sides thereof for receiving the rail 21 therein and for sliding the slidable mount 1 between the two side plates 22 thereof.
  • one of the side plates 22 includes a micro-adjustable screw 23 screwed thereon, and another of the side plates 22 includes a micro-adjustable screw 23 screwed thereon, the micro-adjustable screw 23 and the adjusting screw 24 are in response to the abutting portions 11 of the slidable mount 1 respectively (as shown in FIG. 7 ).
  • 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. 8 ).
  • the pound number of the string e is set, in the meantime, since the string e is in an extension state, the slidable mount 1 of the upper support c3 obliquely moves upward by means 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 abutting portions 11 is biased 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, and since the micro-adjustable screw 23 abuts against the abutting portion11, during the string pulling process, the string e will be kept in a horizontal state.
  • the slidable mount 1 obliquely and downwardly moves toward another abutting portion 11 which is biased against the adjusting screw 24 of the coupling seat 2 (as shown in FIG. 9 ).
  • the adjusting screw 24 is rotated, simultaneously, the heights of the slidable mount 1, upper support c3 and the string puller c1 are descended without causing the grip d1 to contact with the string puller c1, facilitating rotation in different directions.
  • the movement of the string puller c1 and the micro adjustments of the slidable mount 1 may be achieved by means of an electronic controlling system, causing a precise position.
