Definitions

  • the present invention relates to sports goods and more particularly, to a safety racket, which has excellent shock-absorbing effect and the string of the safety racket is protected from external objects.
  • a conventional racket has a head frame, a handle and a connecting portion connected the head frame and the handle.
  • the head frame has a plurality of through holes for passing by a string.
  • the string is passed through one of the through holes outward, then bent around the outer periphery of the head frame, and then passed through another through hole inward.
  • Part of the string is exposed outside the head frame such that the string is probably damaged or broken by external force.
  • due to the string is stopped directly against the outer periphery of the head frame; the shock energy is transmitted from the string directly to the head frame and the handle when the racket hits the ball. The user receives a larger shock power when using the racket.
  • the present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a safety racket, which has excellent shock-absorbing effect.
  • the safety racket comprises a head frame provided with a plurality of through holes, a handle, a connecting portion connected between the head frame and the handle, at least one nail member and a string.
  • the nail member has a head positioned at an outer end of the through hole, and at least one body extending along an axial direction from the head and inserted into the through hole.
  • the body is provided with a distal end protruding from the through hole, and a lateral hole positioned at the distal end and extending along a direction perpendicular to the axial direction.
  • the string passes through the lateral hole of the nail member and interweaved to form a net surface.
  • a safety racket 10 in accordance with the first embodiment of the present invention is a tennis racket.
  • the tennis racket is comprised of a head frame 20, a handle 28, a connecting portion 29, a plurality of nail member 30 and a string 38.
  • the head frame 20 has an outer surface 21, an inner surface 22 and a plurality of through holes 24 extended from the outer surface 21 to the inner surface 22.
  • the through holes 24 each have a large diameter portion 25 positioned at one end thereof and a small diameter portion 26 positioned at the other end thereof.
  • the width of each of the through holes 24 is about equal to the distance between two neighbor sections of the string 38, which is larger than the width of the through hole of the conventional racket.
  • the handle 28 is for gripping by the user.
  • the connecting portion 29 connects between the head frame 20 and the handle 28 as usual racket.
  • the nail members 30 each have a head 32 positioned at an outer end 241 of the through hole 24, and a body 34 extending along an axial direction A from the head 32 and inserted into the through hole 24.
  • the head 32 of the nail member 30 is received in the large diameter portion 25 of the through hole 24, and the body 34 of the nail member 30 is received in the small diameter portion 26 of the through hole 24.
  • the body 34 of the nail member 30 is provided with a distal end 35 protruding from the through hole 24, and a lateral hole 36 positioned at the distal end 35 and extending along a direction X about perpendicular to the axial direction A.
  • the string 38 is passed through the lateral hole 36 of the nail member 30 and interweaved to form a net surface P.
  • the nail member 30 and the head frame 20 are fastened together by tension of the string 38.
  • the extending direction X of the lateral hole 36 of the nail member 30 is about parallel to the net surface P.
  • the string 38 doesn't touch the head frame 20 directly and the nail members 30 are made of shock-absorbing materials, such as nylon, plastic or fiber reinforced plastic, the vibration energy of the racket 10 generated by hitting ball can be absorbed efficiently. Furthermore, the string 38 is passed through the lateral hole 36 of the nail member 30 instead of went around the outer surface 21 of the head frame 20 as the conventional racket. It can be avoided that the string 38 is damaged or even broken by rubbing against ground surface, wall surface or other external object during weaving. Therefore the racket is safe in use and the lifetime of the string can be prolonged.
  • shock-absorbing materials such as nylon, plastic or fiber reinforced plastic
  • a safety racket 40 according to the second embodiment of the present invention further comprises a pad 42 disposed between the head 45 of the nail member 44 and the head frame 48.
  • the pad 42 has a longitudinal hole 43 for receiving the body 46 of the nail member 44.
  • the pad 42 is made of elastic material, such as rubber, PU, PVC or other plastic, to further absorb the vibration of the racket 40 when hitting ball.
  • the lateral hole 47 of the nail member 44 extends along a direction perpendicular to the net surface of the racket 40.
  • a safety racket 50 has a plurality of through holes 52 and nail members 54 each have a width narrower than that of the safety racket of the first embodiment.
  • the distance between the neighbor through holes 52 is about equal to the distance between the neighbor section of the string 56.
  • the structure of this embodiment has the same effect as the first embodiment.
  • a safety racket 60 As shown in FIG. 8 , a safety racket 60 according to the fourth embodiment of the present invention is shown comprising a nail member 62 with a head 63 and two bodies 64.
  • the distal ends 65 of the bodies 64 each are provided with a lateral hole 66 through which the string 68 is passed.
  • the installation of the nail member 62 is more convenience than that of the third embodiment.
  • the number of the nail member is not limited during actual manufacture.
  • Aforesaid safety rackets are embodied by tennis rackets.
  • the spirit of the present invention applies to squash racket, badminton racket or other type of racket.
  • a safety racket 70 according to the fifth embodiment of the present invention is a squash racket.
  • a safety racket 80 according to the sixth embodiment of the present invention has another shape.
  • the spirit of the present invention can be applied to any shape of racket.
