201014631 六、發明說明： · * 【發明所屬之技術領域】 本發明係關於一種羽球拍；特別係關於一種可於更加準確之位 置快速擊回羽毛球之羽球拍。 【先前技術】 羽球拍係包含張弦之拍頭、握把及連結拍頭與握把之拍柄。於 使用羽球拍時，握住握把，以拍頭描繪弧形之方式揮動，以拍頭 上張設之弦撞擊羽毛球而擊飛羽毛球。並且，於複數個選手間進 ® 行連續對打時，必需瞬間預測羽毛球之軌跡，並使用手腕敏捷地 擊回羽毛球。又，要求擊回之羽毛球朝向所瞄準之方向以一定程 度之速度強有力地推進。 一般而言，當開始揮動羽球拍時，由於面積較大之拍頭受到相 對較大之空氣阻力，因而會以拍頭延後之方式拍柄發生變形。若 於揮動中加入該拍柄之變形欲恢復之力，則可強有力地擊打羽毛 球。因此，先前以來一直努力提供為易於揮動而輕量化，進而拍 ©柄會發生適當之變形之羽球拍。 其結果，提出有各種形狀上具有特徵之羽球拍。其中，作為與 拍柄之剖面形狀相關者，有如下所述者。 例如，於日本特開平7— 178202號公報中，提出有一種具有剖 面為橢圓形且使橢圓形之長徑與拍頭之擊球面平行之拍柄之羽球 拍。該文獻中記載：藉由採用此種構成，可使變形變得良好，從 而可對抗擊球時之扭曲。 於曰本特開2000— 189544號公報中，提出有一種具有剖面為菱 形且使菱形之較長對角線與拍頭之擊球面平行之拍柄之羽球拍。 201014631 該文獻中記載：藉由採用此種i冓¥，拍柄之變形變得良好。 於曰本特開平11一 19251號公報中，提出有一種於拍柄之外面 之至少一部分設有朝向沿拍柄軸線之方向延伸之凸條與凹條為特 徵之羽球拍。該文獻中記載：藉由採用此種構成，拍柄之變形得 到改善，扭曲剛性變高，傳遞至握把之振動變少。 於曰本特開平8 — 17363號公報中，提出有一種於拍柄之内面之 至少一部分設有朝向沿拍柄軸線之方向延伸之凸肋為特徵之羽球 拍。該文獻中記載：藉由採用此種構成，垂直於擊球面之方向之 變形變得良好，並且朝向沿著擊球面之球拍橫向之變形變小，揮 擺性變得良好。 【發明内容】 雖如上所述般提出有若干種對拍柄之剖面形狀進行了各種設計 之羽球拍，但任一羽球拍均難以迅敏地進行準確之擊打。 於實際之羽毛球比賽中，並不限於始終以位於羽球拍之擊球面 中心之有效擊球區（sweet spot)來擊回羽毛球。尤其於以勉強之 姿勢擊回時，大多不得不以左右偏離有效擊球區之位置擊回羽毛 球（此處所謂左右，係分別指如第1圖所示正對球拍之擊球面時， 貫通拍柄之中心之球拍中心軸之左側與右側）。然而，本發明者們 經過分析後已明確：先前之羽球拍中，於以左右偏離有效擊球區 之位置擊打羽毛球時，拍柄會發生較大之扭曲而擊球面之方向會 改變，由此導致擊回之羽毛球朝向自意料中之方向偏離之方向行 進0 又，近年之羽毛球競技進一步快速連續對打化，尤其頂級選手 迫切期望一種能以敏捷之球拍操作準確、快速地將球擊向所瞄準 201014631 之方向的羽球拍。然而本發明者們經過分析後已明確：先前之羽 球拍中，擊打羽毛球後橫向（左右方向）會產生振動，故而於快 速連續對打時在橫向之振動尚未穩定時便要擊打下個羽毛球。因 此，無法快速將球擊向意料中之方向。 如此，先前之羽球拍存在無法抑制擊球時之拍柄之扭曲及無法 減小擊球後之橫向之振動之問題。 鑒於如此之先前技術之課題，本發明者們以提供一種可於更準 確之位置快速擊回羽毛球之羽球拍為目的而進行了研究。 © 為解決上述課題而反復認真研究之結果，本發明者們發現，藉 由將具有特徵性剖面形狀之錐形部設於拍柄中可達成目的。 本發明係提供一種羽球拍，其係包含張弦之拍頭、握把及連結 前述拍頭與前述握把之拍柄，其特徵在於：前述拍柄之露出部分 包含以前述拍柄之握把侧露出端或以前述拍柄與前述拍頭之接合 部為始端，而朝向末端減小直徑之中空之錐形部；以及於前述錐 形部之始端之拍柄外剖面係為六邊形，前述六邊形之對向之二邊 β 與前述拍頭之擊球面平行，且於前述錐形部之末端之拍柄外剖面 ❹ 係為圓形。 本發明之羽球拍既可僅具有以拍柄之握把側露出端為始端之錐 形部，亦可僅具有以拍柄與拍頭之接合部為始端之錐形部，亦可 皆具有兩方。 本發明之羽球拍較佳係為，自錐形部之始端直至末端為止之拍 柄軸方向之長度介於25〜35毫米之範圍内。又，較佳地錐形部之 始端之拍柄之外剖面係為正六邊形。又，較佳地與拍頭之擊球面 垂直之方向上之拍柄剖面直徑隨著自錐形部之始端朝向末端而以 201014631 一定之比例減小。又，較佳地錐形部之始端之包含中空部分之拍 柄剖面積係介於80〜92平方毫米之範圍内，且較佳地錐形部之末 端之包含中空部分之拍柄剖面積係介於30〜37平方毫米之範圍 内。又，較佳地其比（末端/始端）係介於0.32〜0.46之範圍内。 本發明之羽球拍之握把較佳為具有連接樹脂部與木部之構造， 拍柄貫通樹脂部内而嵌插至木部内。進而，較佳地嵌插至木部内 之拍柄之部分係為中空且其外剖面係為圓形，貫通樹脂部之拍柄 之部分亦係為中空且其外剖面係為六邊形。 若使用本發明之羽球拍，則可於更加準確之位置快速擊回羽毛 球。尤其於左右偏離有效擊球區之位置擊回之情形時或者於短時 間内連續擊回之情形時，亦容易敏捷地將羽毛球擊回所瞄準之 處。又，本發明之羽球拍實現了輕量化，並且強度優異，耐久性 亦高。 【實施方式】 以下，詳細說明本發明之羽球拍。再者，於本說明書中使用「〜」 表示之數值範圍係意味著包括「〜」之前後記載之數值作為下限 值及上限值之範圍。又，為便於說明，如第1圖所示，設羽球拍 之拍頭側為上側，設握把側為下側進行說明。又，本說明書中之 錐形部係隨著自始端朝向末端直徑變小。 參照圖式說明本發明之羽球拍。 如第1圖及第3圖所示，本發明之羽球拍1係包含張弦之拍頭 3、握把15及連結拍頭與握把之拍柄13。第1圖及第2圖之羽球 拍包含以拍柄13之握把側露出端23為始端之錐形部7。第3圖及 第4圖之羽球拍包含以拍柄13與拍頭3之接合部24為始端之錐 201014631 形部8。 錐形部7、8之始端23、24之拍柄外剖面為六邊形。六邊形之 對向之二邊係設計成與_之擊球面成騎行1如，如第$圖 所示設六邊形之各邊為31〜36時’使邊31及邊％與拍頭之擊球 面平行。藉由以此方切行設計，於_时充分相拍柄朝向 與擊球面垂直之方向之撓曲量’並且可抑制拍柄之扭曲及橫向之 振動。六邊形之各邊31〜36之長度較佳為全部相等更佳為正六201014631 VI. Description of the Invention: · * Technical Field of the Invention The present invention relates to a badminton racket; in particular, to a badminton racket that can quickly return badminton in a more accurate position. [Prior Art] The badminton racket includes a head of a string, a grip, and a handle that connects the head and the grip. When using the badminton racket, hold the grip and swing in the manner of the head to draw the arc, and hit the badminton on the head of the string to hit the badminton. Moreover, when a plurality of players enter each other in a row, it is necessary to instantaneously predict the trajectory of the badminton and use the wrist to quickly return the badminton. In addition, the badminton that is required to be hit back is strongly advanced at a certain speed in the direction in which it is aimed. In general, when the badminton racket is started to be swayed, the racquet is deformed in such a manner that the head is delayed due to the relatively large air resistance of the head. If the force of the deformation of the handle is restored during the swing, the feather ball can be strongly hit. Therefore, efforts have been made in the past to provide lightweight badminton rackets that are easily deformed for easy waving. As a result, there are proposed badminton rackets having various shapes and features. Among them, as the cross-sectional shape of the handle, there are as follows. For example, Japanese Laid-Open Patent Publication No. Hei 7-178202 proposes a badminton racket having a handle having an elliptical shape and having an elliptical long diameter parallel to the hitting surface of the head. This document describes that by adopting such a configuration, the deformation can be made good, and the distortion at the time of hitting the ball can be counteracted. In Japanese Laid-Open Patent Publication No. 2000-189544, there is proposed a badminton racket having a handle having a rhombic section and having a longer diagonal line of the rhombus parallel to the hitting surface of the head. 201014631 This document describes that the deformation of the handle is good by using such an i冓¥. In Japanese Laid-Open Patent Publication No. Hei 11-19251, it is proposed that at least a part of the outer surface of the handle is provided with a bat which is characterized by a ridge and a concave strip extending in the direction of the shank axis. According to this document, by adopting such a configuration, the deformation of the grip is improved, the twist rigidity is increased, and the vibration transmitted to the grip is reduced. Japanese Patent Publication No. Hei 8-17363 proposes a badminton racket characterized in that at least a part of the inner surface of the handle is provided with a rib extending in the direction of the shank axis. According to this document, by adopting such a configuration, the deformation perpendicular to the direction of the ball striking surface becomes good, and the deformation in the lateral direction of the racket along the striking surface becomes small, and the swing property is improved. SUMMARY OF THE INVENTION Although a plurality of badminton rackets have been proposed which have various designs for the cross-sectional shape of the handle as described above, it is difficult for any of the badminton rackets to be accurately and quickly hit. In the actual badminton competition, it is not limited to always hitting the badminton with a valid spot located at the center of the batter's face. Especially when hitting back in a reluctant position, most of them have to hit the badminton back and forth from the position where the effective hitting area is left and right (here, the so-called left and right, respectively, refers to the hitting surface of the racket as shown in Fig. 1 The left and right sides of the center axis of the racket in the center of the handle. However, the inventors have made it clear after analysis that in the previous badminton racket, when the badminton is hit at a position that deviates from the effective hitting area to the left and right, the handle will be greatly distorted and the direction of the hitting surface will change. As a result, the badminton returned to the direction of deviation from the direction of the self-expected direction. In addition, the badminton competition in recent years has been further rapidly and continuously confronted, especially the top players are eagerly expecting an accurate and fast ball strike with an agile racket operation. A badminton racket in the direction of 201014631. However, the inventors have made it clear after analysis: in the previous badminton racket, the horizontal (left and right direction) will vibrate after hitting the badminton, so the next badminton will be hit when the lateral vibration is not stabilized in the fast continuous match. . Therefore, it is not possible to quickly hit the ball in the desired direction. Thus, the previous badminton racket has the problem of not suppressing the distortion of the handle when hitting the ball and not reducing the lateral vibration after hitting the ball. In view of the problems of the prior art, the present inventors conducted research for the purpose of providing a badminton racket that can quickly return badminton in a more accurate position. © In order to solve the above problems, the inventors have found that it is possible to achieve the object by providing a tapered portion having a characteristic cross-sectional shape in the handle. The present invention provides a badminton racket, which comprises a head of a string, a grip, and a handle connecting the head and the grip, wherein the exposed portion of the handle includes the grip side of the handle The end portion or the tapered portion of the handle portion and the aforementioned head is the beginning end, and the hollow tapered portion of the diameter is reduced toward the end; and the outer cross section of the handle at the beginning of the tapered portion is a hexagon, the aforementioned six The opposite sides β of the edge shape are parallel to the ball striking face of the aforementioned head, and the outer cross section of the handle at the end of the tapered portion is circular. The badminton racket of the present invention may have only a tapered portion with the grip end side of the grip handle as the beginning end, or may have only a taper portion with the joint portion of the grip handle and the head as the beginning end, or both have two square. Preferably, the badminton racket of the present invention has a length in the direction of the shank from the beginning to the end of the tapered portion in the range of 25 to 35 mm. Further, it is preferable that the cross section outside the handle of the tapered portion is a regular hexagon. Further, it is preferable that the diameter of the grip profile in the direction perpendicular to the ball striking face of the head decreases at a certain ratio of 201014631 from the beginning end toward the end of the taper portion. Further, preferably, the cross-sectional area of the handle portion including the hollow portion at the beginning of the tapered portion is in the range of 80 to 92 mm 2 , and preferably the end portion of the tapered portion includes the hollow portion Within the range of 30 to 37 square millimeters. Further, it is preferable that the ratio (end/start) is in the range of 0.32 to 0.46. The grip of the badminton racket of the present invention preferably has a structure in which a resin portion and a wood portion are connected, and the handle is inserted into the resin portion to be inserted into the wood portion. Further, it is preferable that the portion of the handle that is inserted into the wooden portion is hollow and has a circular outer cross section, and the portion of the handle that penetrates the resin portion is also hollow and has an outer cross section that is hexagonal. If the badminton racket of the present invention is used, the feather ball can be quickly returned in a more accurate position. Especially when the left and right are deviated from the position of the effective hitting area or when the back is continuously hit in a short time, it is easy to quickly bounce the badminton back to the aiming position. Further, the badminton racket of the present invention is lightweight, excellent in strength, and high in durability. [Embodiment] Hereinafter, the badminton racket of the present invention will be described in detail. Incidentally, the numerical range expressed by "~" in the present specification means a range including the numerical values described before and after "~" as the lower limit value and the upper limit value. Further, for convenience of explanation, as shown in Fig. 1, the head side of the badminton racket is set to the upper side, and the grip side is set to the lower side. Further, in the present specification, the tapered portion becomes smaller in diameter from the beginning end toward the end. The badminton racket of the present invention will be described with reference to the drawings. As shown in Figs. 1 and 3, the badminton racket 1 of the present invention includes a head 3 for a string, a grip 15 and a handle 13 for connecting the head and the grip. The badminton rackets of Figs. 1 and 2 include a tapered portion 7 having a grip side exposed end 23 of the grip 13 as a starting end. The badminton rackets of Figs. 3 and 4 include a cone 201021331 shaped portion 8 with the joint portion 24 of the grip 13 and the head 3 as the starting end. The outer cross sections of the tips 23, 24 of the tapered portions 7, 8 are hexagonal. The opposite sides of the hexagon are designed to ride with the batting surface of the _. For example, if the sides of the hexagon are 31 to 36 as shown in the figure of Fig., the side 31 and the side are made. The head of the ball is parallel. By cutting the design in this way, the amount of deflection of the handle toward the direction perpendicular to the ball striking face is fully taken at _ and the distortion of the handle and the vibration of the lateral direction can be suppressed. The lengths of the sides 31 to 36 of the hexagon are preferably all equal and more preferably positive six.

From the viewpoint of the winding direction of the sheet, there are an armchair (fine ch (four) type, Z type and t-type (-Μ) type, etc. Further, in terms of the structure of the end portion, it is an open structure carbon. The carbon nanotubes can be widely used when the nanotubes and the ends are closed. For example, the carbon nanotubes can be used. In the present invention, the same type of early use is also used. There is no particular limitation on the method of selecting two or more combinations and using carbon nano f. Carbon = two = the badminton racket and the handle are both carbon nanotubes. Carbon: 2 addition secret is not special The limitation is preferably that the head and the handle are comprehensively included. Preferably, the head and the handle are equal, and the carbon content is not unevenly distributed.

Preferably, it is 5 to 5 wt%, and particularly preferably 12 201014631 0.07 to 3 wt%. The carbon nanotubes are preferably mixed to form a head or a handle. For use in other materials, for example, in the case of manufacturing a head or a handle from a material comprising carbon fibers and a binder, it is preferred to preliminarily mix a carbon nanotube with a binder, and then to prepare a material in combination with the carbon fiber. With such a manufacturing method, the badminton racket to which the carbon nanotubes are added can be easily manufactured using the previous badminton racket manufacturing apparatus. When the carbon nanotubes are mixed with the binder, the carbon nanotubes are preferably sufficiently Disperse in the binder. Further, the carbon fiber or binder used herein can be selected from the carbon fiber or the binder commonly used for badminton rackets. The hollow handle can be obtained, for example, by winding the core material. The material of the material is subsequently produced by removing the core material. For example, it can be manufactured by multi-winding a sheet containing carbon fiber, a carbon nanotube and a binder on a core material made of iron, and then removing the core material. Further, then The surface of the badminton racket of the present invention may be suitably covered in the range of 75 to 94 grams, more preferably in the range of 78 to 89 grams, and particularly preferably in the range of 80 to 84 grams. First _ the former badminton racket has a total weight of 84 grams or less, the strength is small, and there is a risk of breakage during use, but the badminton racket of the present invention is lightweight but has excellent strength. Therefore, there is sufficient period to satisfy The player also maintains durability, and in this sense, the badminton racket of the present invention is also economical. The badminton racket of the present invention has the characteristic configuration as described above, so that the distortion of the handle and the vibration of the lateral direction can be suppressed. The twist of the handle can be evaluated by measuring the twist angle by the method described in the examples described later. The twist angle of the previous badminton racket is usually 26 or more, and the twist angle of the badminton racket of the present invention is 25 or less. It is 22° to 25°, more preferably 22.5 to 13 201014631 24.5°, and particularly preferably 23.0 to 24.5°. Since the badminton racket of the present invention has a small twist angle, it is easy to return the shuttlecock to the aiming position even when the feather ball is hit back at a position where the right and left sides are deviated from the effective hitting area (SWeet Sp〇t). Therefore, the control width of the feather ball drop point when the badminton is hit substantially equal to the long distance of the badminton court can be narrower than the previous one by about 4 cm or more, and the ratio is narrower by more than 1%. Therefore, if the badminton racket of the present invention is used, the control of the bead line can be improved, so that the risk of the outgoing line can be reduced. Further, the vibration in the lateral direction of the grip can be evaluated by measuring the maximum vibration amplitude of the tip end portion in the lateral direction by the method described in the examples. The maximum vibration amplitude of the prior badminton racket is usually 1 mm or more, and the badminton racket of the present invention is 2 mm or less, preferably 1.5 mm or less, more preferably 1 mm or less, and particularly preferably 〇 5 mm or less. The badminton racket of the present invention is suppressed by the lateral vibration, so that the horizontal vibration can be quickly stabilized after hitting the ball, and the next badminton can be hit without the yaw state. Especially if the speed is continuously played against the squad, if the next badminton is hit during the period when the lateral vibration after the 9 胄 ball has not stabilized, there is a problem that the badminton will fly in a different direction from the expected direction, but if the badminton racket of the present invention is used, This can be minimized. That is, even when the badminton is continuously hit back in a short period of time, it is easy to make the badminton return to the aiming position agilely. The bending point in this specification is the point at which the handle bends with maximum curvature when commanding a badminton racket. The badminton racket of the present invention can be moved to the head side by providing a tapered portion having the grip end side as the starting end on the handle. Thereby, the bending point can be made 2 g or more closer to the head side than the previous badminton racket. Specifically, by placing the tapered portion with the grip side exposed end as the starting end on the handle, the distance from the beginning of the tapered portion to the bending point can be made between "〇~19〇毫米In the range, it is preferably in the range of ... ~ 0 201014631 150 mm, more preferably in the range of 12 〇 to 140 mm, and particularly preferably in the range of 125 〜 135 mm. By controlling within such a preferred range, the ball can be quickly struck back to the point of aiming even if the wrist is hit back into the badminton. The position of the bending point can be controlled by adjusting the length of the tapered portion at the beginning of the grip side and the like. Example

The surface spacing outside the opposite sides is a 1 G. G mm. The diameter e of the hollow portion is mm. The end 22 of the tapered portion 8 is. As shown in Fig. 4, the outer cross section is circular and the inner hollow portion is also circular. The outer diameter ^ 〇 h & b is 6.5 m, and the diameter d of the hollow portion is 3.3 mm. The cross-sectional shape of the cylindrical portion 6 coincides with the cross-sectional shape of the end u at the joint portion with the end 22 of the tapered portion 8. The outer diameter of the cylindrical portion 6 becomes larger at a predetermined ratio as it approaches the grip, and the outer cross-section at the grip-side exposed end is larger than the end 22 by ι mm. The handle portion that penetrates the resin portion has a regular hexagonal rhyme. Further, the shank of the insert portion η is embedded. The J surface is a circle having an outer diameter of 75 mm. The head 3 and the handle 13 have a structure in which a sheet containing a binder having a carbon nanotube and a carbon fiber is multi-wound. The twist angle and the maximum vibration amplitude of the badminton racket of the embodiment 2 The badminton racket is of the same degree. #实施例1 17 201014631 (Embodiment 3) The embodiment 2 of the badminton racket is changed to have a length of 30 mm in the axial direction and a length of 30 mm in the axial direction. The hollow tapered portion is otherwise studied in the same manner as the badminton racket of the same configuration as the embodiment. That is, the handle of the embodiment 3 has the length at the beginning end of the grip side of the handle and the length in the axial direction. a hollow tapered portion of the hollow tapered portion of the first embodiment having a length of 30 mm, a hollow tapered portion of the second embodiment having a length of 30 mm in the axial direction, and a circle connecting the ends of the tapered portions The bending angle and the maximum vibration amplitude of the badminton racket of the third embodiment are smaller than those of the badminton rackets of the first embodiment and the second embodiment. The bending point is located 130 mm from the beginning of the tapered portion toward the head side. (Comparative example 1) The change is made to be hollow The diameter of the handle is 7.5 mm in the direction perpendicular to the ball striking face and the cross section is the same shape. Otherwise, the badminton racket having the same structure as that of the embodiment 1 is studied. The badminton racket of Comparative Example 1 having the same diameter and having the same shape as that of the first embodiment has a twist angle which is 1.5 or more larger than that of the badminton racket of the first embodiment. Further, the bending point is the same as that of the first embodiment. The badminton racket was 20 mm or more in comparison with the grip side. Further, the lateral maximum vibration amplitude measured by the same method as in Example 1 was 10 mm or more. As a result, the cross section was circular throughout the entire length of the grip. The commercially available badminton racket (AROMATEC 900 POWER ' AROMATEC 900 TECHNIQUE) is the same, with a twist angle of 26.0 to 26.5° and a maximum vibration amplitude of 12 mm. (Comparative Example 2) 201014631 The profile is the same for the entire length of the handle. Elliptical shape, and the long diameter of the ellipse is parallel to the ball striking surface of the head, and other aspects are studied with the badminton racket of the same structure as in the first embodiment. The bucking point of the badminton racket is The badminton racket of the first embodiment has a larger lateral vibration than the grip side of the handle of 20 mm or more. Further, there is a practical problem that the strength perpendicular to the direction of the ball striking face is weak and the handle is easily broken. Example 3) A badminton with the same structure as the full length of the handle of the hollow, and having the same diagonal shape as the long diagonal of the diamond and the hitting surface of the head, and other aspects are the same as those of the first embodiment. The bending of the badminton racket is 20 mm or more to the grip side as compared with the badminton racket of the first embodiment, and the lateral vibration is also large. Further, there is a difficulty in flexing perpendicular to the direction of the ball striking face. It is difficult to obtain high rebound force when hitting the ball, and the handle is easily distorted.
