Definitions

  • the present invention relates to rackets used for such as badminton.
  • Rackets that are used for badminton and the like generally have a shaft, a frame joined to a tip end side in a longitudinal direction of the shaft, and a handle joined to a rear end side in the longitudinal direction of the shaft, and a plurality of holes for a string to pass through are provided along a circumferential direction of the frame (for example, refer to Patent Literature 1).
  • Strings are strung so that within the frame a plurality of vertical strings that are a region of the strings extending in the longitudinal direction are aligned with intervals therebetween in a width direction orthogonal to the longitudinal direction, and a plurality of horizontal strings that are a region of strings extending in the width direction are aligned with intervals therebetween in the longitudinal direction.
  • a net-like hitting surface is formed.
  • Patent Literature 1 Japanese Laid-open Application No. 2000-42145 Document DE-U-9308902 describes a racket wherein the string holes of the horizontal strings are parallel and extend in in a width direction.
  • the frame area is made small so that high-speed swing is possible, and the speed of a shuttlecock when smashing can be improved.
  • a sweet spot also becomes small, and controllability decreases.
  • the speed of the shuttlecock increases by smashing using an upper portion within the frame (a region to a tip end side in the longitudinal direction), and in particular an experienced player has a tendency to use the upper portion within the frame at the time of hitting.
  • An advantage of some aspects of the present invention is that it is possible to expand the sweet spot to the tip end side in the longitudinal direction within the frame.
  • An aspect of the invention is a racket comprising:
  • a racket includes:
  • a movable range of a string along a width direction strung in a region to the tip end side in the longitudinal direction within the frame can be made long. Therefore, a deformation amount of the string at the time of hitting in the region to the tip end side in the longitudinal direction within the frame can be made large, and the sweet spot to the tip end side in the longitudinal direction within the frame can be expanded.
  • the string along the longitudinal direction is not passed through the through hole, the through hole being for the string along the width direction to pass through, the through hole having the first angle smaller than the second angle.
  • the first angle is zero degrees.
  • the sweet spot to the tip end side in the longitudinal direction within the frame can be expanded more certainly.
  • the through hole is not provided to the rear end side in the longitudinal direction than the center of the frame, the through hole being for the string along the width direction to pass through, the through hole having the first angle smaller than the second angle.
  • the sweet spot to the rear end side in the longitudinal direction within the frame can be suppressed from becoming wider than necessary.
  • the penetrating direction of the through hole is along the normal direction to the inner peripheral surface in the position provided with the through hole, the through hole being for the string along the longitudinal direction to pass through.
  • the sweet spot can be suppressed from expanding more than necessary in the longitudinal direction.
  • a badminton racket as a racket according to this invention is given as an example to explain the Embodiments.
  • Fig. 1 shows a front view and a perspective view of the badminton racket (hereinbelow, racket 1) .
  • racket 1 shows a front view and a perspective view of the badminton racket (hereinbelow, racket 1) .
  • racket 1 is a front view of an upper half of a frame 10 of the racket 1.
  • the racket 1 has a shaft 20, the frame 10 joined to the tip end side in the longitudinal direction of the shaft 20, a handle 30 joined to the rear end side in the longitudinal direction of the shaft 20, strings 40 stretched tightly in the inner side of the frame 10, and grommets 50 through which the strings 40 are passed.
  • a direction orthogonal to the longitudinal direction on a hitting surface of the racket 1 (on a plane along the hitting surface) is called a width direction
  • a direction orthogonal to the hitting surface of the racket 1 is called a thickness direction.
  • the shape of the frame 10 is a substantially oval shape extending in the longitudinal direction. Further, the frame 10 is provided with a plurality of string holes 11 (corresponds to through holes) with intervals therebetween along a circumferential direction of the frame 10 over almost the entire perimeter of the frame 10, the string holes 11 being for the strings 40 to pass through, and the string holes 11 penetrating from an inner peripheral surface 10a thereof to an outer peripheral surface 10b thereof. As shown in Fig. 2 , the grommet 50 has a cylindrical portion 51 and a top portion 52, and the cylindrical portion 51 and the top portion 52 are provided with a hole for the string 40 to pass through. The cylindrical portion 51 of the grommet 50 is passed through the string hole 11, a tip end of the cylindrical portion 51 protrudes from the inner peripheral surface 10a of the frame 10, and the top portion 52 is engaged to the outer peripheral surface 10b of the frame 10.
  • the string 41 that is passed through the string holes 11 (grommet 50) from an inner side of the frame 10 to the outside of the frame 10 is turned back along the outer peripheral surface 10b of the frame 10, and an action of passing the string through the next string hole 11 (grommet 50) is repeated.
  • a plurality of "horizontal strings 41" which is a region of the strings 40 along the width direction are strung with intervals therebetween in the longitudinal direction and a plurality of "vertical strings 42" which is a region of the strings 40 along the longitudinal direction intersecting the horizontal strings 41 are strung with intervals therebetween in the width direction.
  • a net-like hitting surface is formed.
  • a recessed portion 12 is provided in the outer peripheral surface 10b, and openings of the string holes 11 are provided in the recessed portion 12, thus the string 40 is turned back in the recessed portion 12.
  • Fig. 3A and Fig. 3B are drawings showing a difference in the movable range of the horizontal string 41 due to a difference in the penetrating direction of the string holes 11.
  • the horizontal string 41 that passes through the sides is longer than the horizontal string 41 that passes through the end portions in the longitudinal direction
  • the vertical string 42 that passes through the top are longer than the vertical string 42 that passes through the end portions in the width direction, and a deformation amount of the strings 40 at the time of hitting with the central portion within the frame 10 is large, thus the central portion within the frame 10 becomes the sweet spot.
  • the racket 1 in this Embodiment aims to expand the sweet spot to the tip end side in the longitudinal direction within the frame 10.
  • an angle ⁇ 1 (hereinbelow, also referred to as a "penetrating angle", and corresponds to a first angle) formed by the width direction and a penetrating direction of the string holes 11 positioned to the tip end side in the longitudinal direction than a center O of the frame 10, of the plurality of the string holes 11 through which the horizontal strings 41 are passed, is made smaller than an angle ⁇ 2 (hereinbelow, also referred to as a "normal angle", corresponds to a second angle) formed by the width direction and a normal direction of the inner peripheral surface 10a of the frame 10 in a position provided with the string hole 11 (a vertical direction in respect to a tangent to the inner peripheral surface 10a).
  • the penetrating angle ⁇ 1 of the eight string holes 11 in total are made smaller than normal angle ⁇ 2, the eight string holes 11 being 2 string holes 11a(3), 11b(3) for a third horizontal string 41 (3) from the tip end side in the longitudinal direction to pass through, 2 string holes 11a(4), 11b(4) for a fourth horizontal string 41(4) to pass through, 2 string holes 11a(6), 11b(6) for a sixth horizontal string 41(6) to pass through, and 2 string holes 11a(8), 11b(8) for an eighth horizontal string 41(8) to pass through, of the horizontal strings 41 aligned in the longitudinal direction.
  • a cylindrical portion 51 of the grommet 50 is passed through along the string hole 11, so that the angle ⁇ 1 formed by the axial direction of the grommets 50 that are passed through the eight horizontal string holes 11 and the width direction are also smaller than the normal angle ⁇ 2.
  • the horizontal string holes 11 are penetrated so that the penetrating direction of the horizontal string holes 11 are formed along the width direction as much as possible (a direction in which the horizontal string 41 extends within the frame 10).
  • the horizontal string holes 11 are penetrated so that the penetrating angle of the horizontal string holes 11 come as close as possible to zero degrees.
  • the penetrating angle ⁇ 1 of the horizontal string holes 11a(6), 11b(6), 11a(8), 11b(8) through which the sixth and the eighth horizontal strings 41(6), 41(8) pass is zero degrees.
  • the penetrating angle ⁇ 1 of the horizontal string holes 11 through which the third and fourth horizontal strings 41(3), 41(4) pass may be made as zero degrees, or on the other hand, the penetrating angle ⁇ 1 of the horizontal string holes 11 for the sixth and eighth horizontal strings 41(6), 41(8) to pass through may be made larger than zero degrees, or the penetrating angle ⁇ 1 of the 2 horizontal string holes 11 for a horizontal string 41 with the same number to pass through may vary. Further, the penetrating angle of the string holes 11 for the first and the second horizontal strings 41(1), 41(2) to pass through may be made smaller than the normal angle.
  • the penetrating direction of the horizontal string holes 11 (the horizontal string holes 11a(4), 11b(4) for the fourth horizontal string 41(4) to pass through in the drawing) is along the normal direction.
  • the horizontal string 41(4) bends relatively largely in positions p3, p4 where the horizontal string 41(4) passes through the inner peripheral surfaces 10a of the frame 10, so that the movement of the horizontal string 41(4) is fixed in the positions p3, p4.
  • the movable range in the width direction of the horizontal string 41(4) becomes a length Lb between the inner peripheral surfaces 10a of the frame 10.
  • the penetrating angle ⁇ 1 of the horizontal string holes 11 is made smaller than the normal angle ⁇ 2. Therefore, as shown in Fig. 3A , the angle that the horizontal string 41 (4) bends in positions where the horizontal string 41(4) passes through the inner peripheral surfaces 10a of the frame 10 can be made smaller compared to the case in Fig. 3B , and the horizontal string 41(4) can be bent in the positions p1, p2 where the horizontal string 41(4) passes through the outer peripheral surfaces 10b of the frame 10.
  • the movable range of the horizontal string 41(4) in the width direction can be made as a length La between the outer peripheral surfaces 10b of the frame 10, and the movable range of the horizontal string 41(4) can be made longer than when compared to the case in Fig. 3B .
  • the penetrating angle ⁇ 1 of the horizontal string holes 11 zero degrees, the movable range of the horizontal string 41 (4) can be made long more certainly.
  • a deformation amount of the string 40 can be made large at the time of hitting in a region more to the tip end side in the longitudinal direction than the central portion within the frame 10 and repulsion can be improved.
  • the movable range of the horizontal string 41 which passes through the eight horizontal string holes 11 positioned in between the top and the sides of the frame 10 can be made close to the movable range of the horizontal string 41 passing the central portion of the frame 10, thus the sweet spot to the tip end side in the longitudinal direction within the frame 10 can be expanded and controllability can be improved. Therefore, even when the area of the frame 10 is made small to make high-speed swing possible, the sweet spot can be prevented from becoming small.
  • the flight and the hitting feeling of the shuttlecock at the time of smashing using the region to the tip end side in the longitudinal direction in the frame 10 can be improved, and the racket 1 of this Embodiment can be provided as the racket 1 appropriate for a player who uses the region to the tip end side in the longitudinal direction within the frame 10.
  • the penetrating direction of the string holes 11 other than the eight horizontal string holes 11 positioned between the top and the sides of the frame 10 is made to be along the normal direction to the inner peripheral surface 10a of the frame 10 in the positions where each of the string holes 11 are provided. Supposing that, the penetrating direction of all the string holes 11 for the horizontal string 41 to pass through is made to be along the width direction and the penetrating direction of all the string holes 11 for the vertical string 42 to pass through is made to be along the longitudinal direction, then the sweet spot expands too much. In that case, it becomes difficult to determine which region within the frame 10 is used for hitting and conversely controllability decreases. Further, the speed of the shuttlecock decreases.
  • the experienced player has a tendency to use the tip end side in the longitudinal direction of the frame 10 at the time of hitting, so that there is no need to make the sweet spot in the position to the rear end side in the longitudinal direction than the center of the frame 10 wide. Therefore, as with the racket 1 in this Embodiment, by making the penetrating direction of the string hole 11 provided to the rear end side in the longitudinal direction of the frame 10 to be along the normal direction, only the sweet spot to the tip end side in the longitudinal direction within the frame 10 can be expanded, and it is possible to suppress the sweet spot to the rear end side in the longitudinal direction from expanding more than necessary.
  • the longitudinal direction of the racket 1 is longer than the width direction, and the movable range of the vertical string 42 can be made wider than that of the horizontal string 41, thus there is no need to make the movable range of the vertical string 42 wide. Therefore, as with the racket 1 of this Embodiment, by making the penetrating direction of the string holes 11 for the vertical string 42 to pass through to be along the normal direction, it is possible to suppress the sweet spot from expanding more than necessary in the longitudinal direction.
  • the drilling processing of the frame 10 can be made easy.
  • the penetrating angle ⁇ 1 of the string hole 11 through which the horizontal string 41 is passed and through which the vertical string 42 is not passed, of the string holes 11 positioned to the tip end side in the longitudinal direction than the center O of the frame 10, is made smaller than the normal angle ⁇ 2.
  • the penetrating direction of the string hole 11 through which the horizontal string 41 and the vertical string 42 are passed is made to be along the normal direction.
  • the penetrating direction of the string holes 11a(5), 11b(5), 11a(7), 11b(7) through which the fifth and the seventh horizontal strings 41(5), 41(7) from the tip end side in the longitudinal direction pass is along the normal direction.
  • the string hole 11 for two strings 40 to pass through has a larger hole diameter compared to the string hole 11 for only one string 40 to pass through, and the movement of the horizontal string 41 in the inner peripheral surfaces 10a of the frame 10 is less prone to be restricted, and the movable range of the horizontal string 41 is less prone to become short. Therefore, even in the case that the penetrating direction of the string hole 11 for two strings 40 to pass through is made to be along the normal direction, the sweet spot can be prevented from becoming small. In other words, it is not necessary to make the hole diameter of the string hole 11 through which only the horizontal string 41 passes large in order to expand the sweet spot, thus the strength of the frame 10 can be enhanced. Further, by making the penetrating direction of the string hole 11 through which two strings 40 are passed to be along the normal direction, the drilling processing of the frame 10 can be made easy.
  • a bending angle ⁇ 3 of the vertical string 42 becomes a right angle or an angle close to a right angle.
  • a stress at the time of hitting concentrates in a corner portion where the vertical string 42 bends. Therefore, by making the penetrating direction of the string hole 11 through which two strings 40 pass to be along the normal direction, a bending angle of the vertical string 42 can be made gentle, and the stress concentration at the time of hitting can be suppressed, thus decrease in strength of the vertical string 42 and the grommets 50 can be suppressed.
  • the penetrating direction of the string holes 11 through which the horizontal string 41 and the vertical string 42 pass and that are positioned to the tip end side in the longitudinal direction than the center O of the frame 10 may be made to be along the width direction.
  • the raw material (for example, resin) of the grommets 50 that are passed through the eight horizontal string holes 11 positioned in between the top and the sides of the frame 10 a harder raw material than a raw material of the grommets 50 that are passed through the other string holes 11 is used. In this way, a frictional drag between the grommets 50 that are passed through the horizontal string holes 11 and the horizontal strings 41 can be made smaller than a frictional drag between the grommets 50 that are passed through other string holes 11 and the horizontal strings 41.
  • the horizontal string 41 that is passed through the horizontal string hole 11 becomes easier to move, a deformation amount of the string 40 at the time of hitting in a region to the tip end side in the longitudinal direction within the frame 10 can be made larger, and repulsion can be further improved.
  • the sweet spot to the tip end side in the longitudinal direction within the frame 10 can be expanded more certainly.
  • the region to the tip end side in the longitudinal direction of the frame 10 has a shorter length in the width direction compared to the region to the rear end side in the longitudinal direction.
  • the horizontal strings 41 that pass through the region to the tip end side in the longitudinal direction of the frame 10 have a shorter movable range than the horizontal strings 41 that pass through the region to the rear end side in the longitudinal direction, thus the racket 1 in this Embodiment becomes more effective.
  • the racket 1 may have a tapered shape with the top of the frame 10 flattened.
  • the badminton racket is provided as an example, but it is not limited thereto.
  • this invention may be applied to such as a tennis racket or a squash racket.
  • the racket 1 with the string 40 stretched tightly within the frame 10 is provided as an example, but it is not limited to this, and the racket does not have to have the string 40 stretched tightly therein.
