Description

本考案は、ゴルフクラブヘッドに関するもので、特に、重り単元の重り比率を調整することにより、重心位置を変えることができるゴルフクラブヘッドに係るものである。 The present invention relates to a golf club head, and more particularly to a golf club head whose center of gravity can be changed by adjusting a weight ratio of a weight unit.

従来のゴルフクラブヘッドとして、例えば中華民国新型公告番号第Ｍ３０３７５２号「調整可能式な重りのゴルフクラブヘッド」（特許文献１を参照）において、従来のゴルフクラブヘッドにはヘッド本体と複数個の重りが含まれる。上記ヘッド本体には複数個の収容凹部が設けられ、上記収容凹部は上記重りを収容するのに用いられる。上記それぞれの重りにはそれぞれ前支持部材、後支持部材とスリーブが形成される。上記前支持部材は円錐形体からなり、そしてその一端には比較的大きい外径のヘッドが設けられる。上記前支持部材には他にねじ孔が設けられ、上記ねじ孔は上記前支持部材の二端面を貫穿するように形成される。上記後支持部材には頭部とねじ桿が形成され、上記頭部も円錐形体からなり、そして上記頭部の小径端部面は上記ねじ桿とは互いに連接するように形成される。上記スリーブは円形の筒体からなり、そして選択的に多種の比重の異なる金属材質（例えば、ステンレス、チタン、ニッケルまたは銅等）からなることができる。上記スリーブには軸孔が設けられ、上記軸孔は上記スリーブの二端面を貫穿するように形成されるようにとしたものがある。 As a conventional golf club head, for example, in the New Republic of China No. M303752 “Golf Club Head with Adjustable Weight” (see Patent Document 1), the conventional golf club head includes a head body and a plurality of weights. Is included. The head body is provided with a plurality of receiving recesses, and the receiving recesses are used to receive the weights. A front support member, a rear support member, and a sleeve are formed on each of the weights. The front support member has a conical shape, and a relatively large outer diameter head is provided at one end thereof. The front support member is provided with another screw hole, and the screw hole is formed so as to penetrate the two end surfaces of the front support member. The rear support member is formed with a head and a screw rod, the head is also formed of a conical shape, and the small-diameter end surface of the head is formed so as to be connected to the screw rod. The sleeve is made of a circular cylinder and can be made of various metal materials having different specific gravity (for example, stainless steel, titanium, nickel, copper, etc.). Some sleeves are provided with shaft holes, and the shaft holes are formed so as to penetrate two end surfaces of the sleeve.

上記重りを組み立てる時、先ず上記前支持部材と後支持部材をそれぞれ上記スリーブの二端から上記軸孔の中に置き入れ、そして上記後支持部材のねじ桿を上記前支持部材のねじ孔の中に対応するように螺合させる。それから、上記重りを上記ヘッド本体の収容凹部の内に置き入れ、そして再び上記後支持部材を回転するように駆動させることにより、上記前支持部材は上記ねじ桿に沿って記後支持部材の頭部に向かって移動する。上記前支持部材と上記頭部の間の距離が持続的に短縮することに従って、上記前支持部材と頭部の円錐の形状によって段々と上記スリーブの環状周壁が外へ拡張するのを圧迫することにより、上記スリーブの環状周壁と上記収容凹部の内周壁面は緊密に貼り合うように形成され、さらに上記重りを上記収容凹部の内に位置決めさせる。また、上記前支持部材が上記ねじ桿に沿って上記後支持部材の頭部に向かって移動することに従って、上記ねじ桿も上記ねじ孔を貫穿して上記収容凹部の底部の固定孔の中に螺設されることにより、上記重りが安定して上記収容凹部の中に位置決めされるのを確保することができる。 When assembling the weight, first, the front support member and the rear support member are respectively placed into the shaft hole from the two ends of the sleeve, and the screw rod of the rear support member is inserted into the screw hole of the front support member. Screwed to correspond to. Then, the front support member is moved along the screw rods by placing the weight in the receiving recess of the head body and driving the rear support member to rotate again. Move towards the department. As the distance between the front support member and the head continuously shortens, the annular peripheral wall of the sleeve is gradually expanded outward by the shape of the cone of the front support member and the head. As a result, the annular peripheral wall of the sleeve and the inner peripheral wall surface of the receiving recess are formed so as to adhere closely, and the weight is positioned in the receiving recess. Further, as the front support member moves along the screw rod toward the head of the rear support member, the screw rod penetrates the screw hole and enters the fixing hole at the bottom of the housing recess. By being screwed, it is possible to ensure that the weight is stably positioned in the receiving recess.

中華民国新型公告番号第Ｍ３０３７５２号Republic of China new announcement number M303752

上記のような従来のゴルフクラブヘッドにおいては、一般として下記の問題点を有している。上記スリーブは金属材質からなるため、仮に上記スリーブが異なる重りの効果を有する時、上記スリーブの体積を変えることにより、または選択的に異なる比重の金属材質からなるように行うことによって異なる重りの形態を表すことができる。しかし、金属材質の比重は普遍的に高過ぎるため、さらに各種の金属材質間の比重の差異は比較的小さいため、上記金属材質のスリーブの重りとしての範囲が制限されることにより（すなわち最も軽いスリーブと最も重いスリーブの間の重量の差異が比較的小さい）、ゴルフクラブヘッドの重りとしての比率を選択するのに影響を及ぼしてしまうという問題点があった。 Conventional golf club heads as described above generally have the following problems. Since the sleeve is made of a metal material, if the sleeve has the effect of different weights, different weight forms can be obtained by changing the volume of the sleeve or by selectively making the sleeve made of a metal material having a different specific gravity. Can be expressed. However, since the specific gravity of the metal material is universally too high, and the difference in specific gravity between various metal materials is relatively small, the range of the weight of the metal material sleeve is limited (that is, the lightest). The difference in weight between the sleeve and the heaviest sleeve is relatively small), which has an effect on the selection of the weight ratio of the golf club head.

その他に、上記金属材質のスリーブの径の拡張の変形量が比較的小さいため、さらにその外表面の摩擦の係数が比較的低いため、仮に上記スリーブの環状周壁と上記収容凹部の内周壁面の間の摩擦力では、依然として上記重りを安定して上記収容凹部の中に位置決めさせることができない。そのため、従来のゴルフクラブヘッドでは余分に上記ねじ桿を利用して上記固定孔に固設しなければ、上記重りを安定して上記収容凹部の中に位置決めすることができない。しかし、従来のゴルフクラブヘッドにおいては沢山の位置決めの構造が設置されるため、製造上において複雑性が増えてしまうだけではなく、製造コストも高くなるという問題点があった。このように、上記のような従来のゴルフクラブヘッドをさらに改良しなければならない。 In addition, since the deformation amount of the expansion of the diameter of the metal sleeve is relatively small and the coefficient of friction of the outer surface thereof is relatively low, the annular peripheral wall of the sleeve and the inner peripheral wall surface of the housing recess are temporarily assumed. With the frictional force in between, the weight cannot be stably positioned in the receiving recess. For this reason, in the conventional golf club head, the weight cannot be stably positioned in the housing recess unless the screw hole is used to fix the fixing hole to the fixing hole. However, since many positioning structures are installed in the conventional golf club head, there is a problem that not only the manufacturing complexity increases but also the manufacturing cost increases. Thus, the conventional golf club head as described above must be further improved.

本考案はこのような問題点に鑑みて考案されたものであって、その第一の目的とするところは、重り単元の重りの比率は比較的多くの選択性を有し、さらにゴルフクラブヘッドの重心位置の変化性を高めることができるゴルフクラブヘッドを提供しようとすることにある。 The present invention has been devised in view of such problems, and the first object thereof is to provide a relatively high selectivity in the weight ratio of the weight unit, and further to a golf club head.

重り単元１を位置合わせるように組立孔９１の中に置き入れた後、工具Ｔを利用して駆動凹部１２２に挿入し、そして係止部材１２を回動させることにより、ねじ桿１２４を持続的にねじ孔１３２にねじ込むことができる。ねじ桿１２４が推し進むに従って、係止頭端部１２１と環状円錐面１３１３の間の相対的な距離も段々と短縮するように形成されるため、小径端部１３１１は軸孔１３２の中に進入される。そして環状円錐面１３１３も軸孔１３２の内周壁面を押圧するように形成されることにより、塑性重りカバー１１を半径方向へ拡径するように圧迫し、これによって塑性重りカバー１１は組立孔９１の内周壁面と互いに緊密かつ固定して貼り合うことができる、そのため、重り単元１を組立孔９１の中に位置決めする目的を達成することができる。 After placing the weight unit 1 in the assembly hole 91 so as to align, the screw T 124 is continuously inserted by inserting it into the drive recess 122 using the tool T and rotating the locking member 12. Can be screwed into the screw hole 132. As the screw rod 124 is pushed forward, the relative distance between the locking head end 121 and the annular conical surface 1313 is formed to be gradually reduced, so that the small diameter end 1311 enters the shaft hole 132. Is done. The annular conical surface 1313 is also formed so as to press the inner peripheral wall surface of the shaft hole 132, thereby pressing the plastic weight cover 11 so as to expand in the radial direction, whereby the plastic weight cover 11 is assembled into the assembly hole 91. Therefore, the object of positioning the weight unit 1 in the assembly hole 91 can be achieved.

図６は本考案のゴルフクラブヘッドの係止部材が当接座と塑性重りカバーの間の当接状態を解除した使用状況の説明図で、図７は本考案のゴルフクラブヘッドの重り単元が組立孔から離脱した状態の説明図である。図６、７を参照すると、例えば、重り単元１を組立孔９１から離脱させようとする時、工具Ｔを利用して駆動凹部１２２の中に挿入し、そして係止部材１２を反対方向に回転するように駆動させることで、係止頭端部１２１と環状円錐面１３１３の間の相対的な距離もねじ桿１２４の反対方向への回動によって段々と増えていく。そのため、座体１３１の環状円錐面１３１３も軸孔１１３から離脱することにより、塑性重りカバー１１の外周壁面は軸孔１１３の内周壁面と緊密に貼り合わないように形成されるため、使用者は工具Ｔを利用して重り単元１を組立孔９１の中から取り出すことができる。 FIG. 6 is an explanatory view of the usage state in which the locking member of the golf club head of the present invention releases the contact state between the contact seat and the plastic weight cover, and FIG. 7 shows the weight unit of the golf club head of the present invention. It is explanatory drawing of the state which removed from the assembly hole. 6 and 7, for example, when the weight unit 1 is to be removed from the assembly hole 91, it is inserted into the drive recess 122 using the tool T, and the locking member 12 is rotated in the opposite direction. By driving in such a manner, the relative distance between the locking head end portion 121 and the annular conical surface 1313 also increases gradually as the screw rod 124 rotates in the opposite direction. Therefore, the annular conical surface 1313 of the seat body 131 is also detached from the shaft hole 113, so that the outer peripheral wall surface of the plastic weight cover 11 is formed so as not to be closely bonded to the inner peripheral wall surface of the shaft hole 113. Can take out the weight unit 1 from the assembly hole 91 using the tool T.

上述の如く、本考案のゴルフクラブヘッドによれば、本考案の塑性重りカバー１１は弾力性を有するプラスチック材質から比重の高い金属粉末を混合して製成するものであるため、同時に弾力性を有するプラスチック材質と比重の高い金属粉末の特性を保有することができ、故にその表面の摩擦係数は一般金属表面の摩擦係数より高く、そして比較的良好な弾性変形の能力を有するため、塑性重りカバー１１が環状円錐面１３１３に押圧される時、塑性重りカバー１１はさらに緊密に組立孔９１の内周壁面に貼り合うことができるように形成され、そして滑動が生じ易くなく、両者間の結合の信頼性を大幅に高めることができる。 As described above, according to the golf club head of the present invention, the plastic weight cover 11 of the present invention is made by mixing a metal powder having a high specific gravity from a plastic material having elasticity, and at the same time, has elasticity. Because it has the characteristics of plastic material and high specific gravity metal powder, its surface friction coefficient is higher than that of general metal surface, and it has relatively good elastic deformation ability, so the plastic weight cover 11 is pressed against the annular conical surface 1313, the plastic weight cover 11 is formed so that it can be more tightly attached to the inner peripheral wall surface of the assembly hole 91, and is not prone to sliding, and the connection between the two Reliability can be greatly increased.

また、本考案のゴルフクラブヘッドによれば、上記弾性力を有するプラスチック材質と金属粉末の間の材質の比率をさらに変えることにより、塑性重りカバー１１の単位重量を調整することができるため、その他の比重の金属材質を取り換える必要がなく、または塑性重りカバー１１の全体の体積を変える必要がない。また、弾性力を有するプラスチック材質と金属粉末の間には比較的大きい比重の差（例えば、大部分のゴムの密度は１.０ g/cm^３位で、タングステンの密度は約１９.２５ g/cm^３である）を有することにより、塑性重りカバー１１の単位重量は比較的大きい範囲で選択することができるため、ヘッド本体９が重心の調整上において更なる多くの変化を提供することができる。 According to the golf club head of the present invention, the unit weight of the plastic weight cover 11 can be adjusted by further changing the ratio of the material between the plastic material having the elastic force and the metal powder. It is not necessary to replace the metal material having a specific gravity of or to change the entire volume of the plastic weight cover 11. Also, there is a relatively large difference in specific gravity between the elastic plastic material and the metal powder (for example, the density of most rubber is about 1.0 g / cm ³ , and the density of tungsten is about 19.25 g. by having / cm is ^3), for the unit weight of plastic weight cover 11 which can be selected in a relatively large range, the head main body 9 provides many changes further on adjustment of the center of gravity it can.

本考案は、その精神とび必須の特徴事項から逸脱することなく他のやり方で実施することができる。従って、本明細書に記載した好ましい実施形態は例示のなものであり、限定のなものではない。 The present invention can be implemented in other ways without departing from the spirit and essential features thereof. Accordingly, the preferred embodiments described herein are exemplary and not limiting.
