與不銹鋼制的鐵桿頭相比，純鐵製的鐵桿頭的材料硬度 低，擊球感柔和。但是，由於純鐵製的鐵桿頭的耐磨損性 低，所以桿頭面容易發生劃傷，而且其得分線（桿頭面部 的溝槽）的角緣很快就會變圓，擊球時不容易打出旋球。 在上述日本專利特開平8 - 2 0 6 2 6 0號公開公報與特開平 1 0 - 5 3 7 6號公開公報中記載到，對由軟鐵材或者合金鋼製 成的鐵桿頭進行滲碳處理，可以提高其桿頭面硬度，但這 兩篇專利文獻並沒有記載有關對由純鐵材製成的鐵桿頭進 行滲碳處理的内容。 本創作的目的即在於提供擊球感優良、而ΐ磨損性也好的 高爾夫球桿頭。 (解決問題之手段） 本創作（申請專利範圍第1項）的高爾夫球桿頭，係由至 少桿頭面經滲碳處理過的鐵材製成者，其特徵在於，該鐵 材由純鐵製成。 申請專利範圍第2及3項的南爾夫球桿頭為在申請專利 範圍第1項的基礎上，該純鐵的純度在9 9 . 8 %以上、1 0 0 % 以下，而其中申請專利範圍第3項中的純度為 9 9 . 9 9 5〜9 9 . 9 9 9 9 %的高純度。 312ΧΡ/創作說明書(補件)/94-08/94205925 M289074 申請專利範圍第4及5項的高爾夫球桿頭分別為在申請 專利範圍第2及3項的基礎上，該球桿頭為鐵桿型高爾夫 球桿頭，其桿面角度（1 〇 f t )在2 5 °以上、7 0 °以下。 申請專利範圍第6及7項的高爾夫球桿頭分別為在申請 專利範圍第2及3項的基礎上，該球桿頭為鐵桿型高爾夫 球桿頭，其桿面角度在4 0 °以上、6 5 °以下。Compared with the iron head made of stainless steel, the iron head of pure iron has a low material hardness and a soft feeling of hitting the ball. However, since the iron head of pure iron has low abrasion resistance, the head surface is liable to be scratched, and the corner of the score line (the groove of the head face) is quickly rounded. It is not easy to play a spin. It is described in the above-mentioned Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. The treatment can improve the hardness of the head face, but the two patent documents do not describe the case of carburizing the iron head made of pure iron.

Using a high-purity iron of 99.99 % or more and 100% or less, it is possible to obtain an extremely soft feeling of hitting the ball, and at the same time, it can also be improved. In this creation, due to the club made of the pure iron material The head is carburized, so its wear resistance is also very good. Although the present invention is applied to the iron head as described above, the problem of insufficient strength of the head face due to the pure iron material is preferable to the thickness near the center of gravity of the hitting portion on the head face, so that the thickness is strong. The thickness is 3 · 5 to 1 5 mm. Further, in the case of increasing the thickness in the vicinity of the center of gravity of the face, when the ball is hit near the position of the head center (when the center point is hit), and in order to suppress the weight of the iron head, When increasing the thickness in the vicinity of the position of the center of gravity of the rod, it is preferable to make the thickness in the vicinity of the thickness of the other portion small, specifically, the thickness of the rod tip side and the heel side is closer to the core position than the weight of the head portion. In the present creation, it is preferred that the head surface of the head face is carburized to have a head hardness of about HV 180 to 900. [Embodiment] The present invention will be described in detail below with reference to the drawings. Fig. 1 is a perspective view of the iron-type golf club head as seen from the rear, and a side view of the golf club head as seen from the tip side. The iron head type golf club head 1 has a head face portion 2 and a head face 2 f having a planar shape in which the head face portion 2 is inserted, the hosel 312XP/Creation Manual (supplement)/94-08/94205925 1 0 0 % or less is preferably 0. 0 2 %, and 5 is stainless. The face of the club face is 使用者, so the degree of weight added to the face of the club head is excellent. The specific gravity of the head and face is centered on the heart. Fig. 2 shows the sheath portion 3, the portion 3 connected to the rod heel side of the 8 M289074 head face portion 2, and the shaft insertion portion 4 is provided with the shaft insertion hole 4. The front end of the golf club shaft is inserted into the shaft insertion hole 4 and fixed by an adhesive. The illustrated golf club head 1 is a wedge club head having a face angle of about 45°. On the back surface of the golf club head 1, a convex portion 5 projecting rearward is provided in the vicinity of the center of the rod tip and the direction of the heel. Except for the convex portion 5, the thickness of the head face portion 2 is substantially the same in the direction of the tip and the heel.
而且，桿頭面部2的厚度在桿底部6 —側（桿底部側） 最大，越往上方厚度逐漸變小。 該凸5位於桿頭面部2的重心位置附近的後方（使球 桿頭1觸地狀態的後方）。 設置凸部5的範圍優選為球桿頭1的桿尖及桿跟方向上 全長的1 0〜9 0 %，2 0〜8 0 %左右更加理想。 優選使凸部5的最下部到達桿底部6，這樣可以降低球 桿頭1的重心。另外，在該實施例中，如圖2所示，使凸 部5的外桿頭面與桿底部6平滑地連續。由此，可使凸部 5的下部用作球桿頭1的反彈部。 優選使用純度為9 9 . 9 9 5 %以上、1 0 0 %以下，例如 9 9 . 9 9 5〜9 9 . 9 9 9 9 %的高純度的純鐵作為該高爾夫球桿頭1 的材料。該球桿頭1被進行了滲碳處理，使得其在從桿頭 面起向内約0.2〜0.5mni左右的範圍内擴散有石厌。渗^厌處理 既可以僅對桿頭面2 f進行，也可以對整個球桿頭進行。 滲碳處理可以為氣體滲碳處理、電漿滲碳處理等中之任何 ^種0 312XP/創作說明書(補件)/94-08/94205925 M289074 通過該滲碳處理，使球桿頭1的桿頭面硬度達到Η V 1 8 0〜 9 0 0，優選達到Η V 3 0 0以上，Η V 3 0 0〜8 0 0貝^更力口理想。 由於這樣製成的高爾夫球桿頭1為由高純度的純鐵材製 成的，因此擊球感柔和，而且不鏽性優良。另外，由於對 其進行了滲碳處理，所以其耐磨損性也良好。Further, the thickness of the head face portion 2 is the largest at the side (the bottom side of the rod) of the rod bottom portion 6, and the thickness becomes gradually smaller as it goes upward. The projection 5 is located rearward of the position of the center of gravity of the head face portion 2 (the rear side of the club head 1 is in contact with the ground). The range in which the convex portion 5 is provided is preferably 10 to 90% of the total length of the club head 1 and the direction of the heel direction, and more preferably about 20 to 80%. It is preferable that the lowermost portion of the convex portion 5 reaches the rod bottom portion 6, so that the center of gravity of the club head 1 can be lowered. Further, in this embodiment, as shown in Fig. 2, the outer head face of the projection 5 is smoothly continuous with the rod bottom 6. Thereby, the lower portion of the convex portion 5 can be used as the rebound portion of the club head 1. It is preferable to use pure iron having a purity of 99.95 % or more and 100% or less, for example, 9 9 9 9 5 9 9 9 9 9 % as the material of the golf club head 1 . The club head 1 is carburized so that it diffuses in a range of about 0.2 to 0.5 mni inward from the head surface. The osmosis treatment can be performed only on the head face 2f or on the entire club head. The carburizing treatment may be any of the gas carburizing treatment, the plasma carburizing treatment, etc. 0 312XP/Creation Manual (Supplement)/94-08/94205925 M289074 By the carburizing treatment, the rod of the club head 1 is made The hardness of the head surface reaches Η V 1 8 0~ 9 0 0, preferably Η V 3 0 0 or more, and Η V 3 0 0~8 0 0 Bay ^ is more ideal. Since the golf club head 1 thus produced is made of a high-purity pure iron material, the hitting feeling is soft and the rust is excellent. Further, since it is carburized, it is also excellent in abrasion resistance.
通過進行滲碳處理，一般的用於鐵桿頭的S 2 0 C等的軟 鐵材的桿頭面會硬化。但是當由於劃傷等原因使得滲碳部 分消失後，這樣的桿頭面會生銹。然而，如果使用高純度 的純鐵，則可以通過對整個球桿頭進行滲碳處理來保持其 形狀，而且，即使有較深的傷痕，也不易生銹。 由於在該高爾夫球桿頭1上設置了凸部5，所以桿頭面 部2的強度得以提高，同時打擊中心點狀態下擊到球時的 手感極佳。另外由於重心深度（前緣至重心位置的水平方 向上的距離。）較深，所以其甜蜜區的範圍較廣。 由於該高爾夫球桿頭1的凸部5到達了桿底部6，所以 其重心低，易於起球。 本創作的高爾夫球桿頭適用於桿面角度在2 5 °以上、7 0 。以下的鐵桿頭，尤其適合於該角度在4 0 °以上、6 5 °以下 的楔形球桿頭，不過，其也適用於由鐵材料製成的草地木 桿的球桿頭（F a i r w a y W 〇 ◦ d H e a d )或實用球桿的球桿頭 (Utility Head)0 此外，也可以在本創作的球桿頭的桿底部安裝鎢等比重 高的材料。另外也可以在桿頭面部的内部設置空間，然後 在其中裝填橡膠、彈性體等的吸收振動的材料。 10 312XP/創作說明書(補件)/94-08/94205925 M289074 【圖式簡單說明】 圖1為從後方看實施例中的鐵桿型的高爾夫球桿頭時所 看到的立體圖。 '圖2為實施例中的鐵桿型的高爾夫球桿頭的側視圖。 【主要元件符號說明】 1 南爾夫球桿頭 2 桿頭面部 2 f 桿頭面By performing the carburizing treatment, the head surface of a soft iron material such as S 2 0 C which is generally used for an iron head is hardened. However, when the carburized portion disappears due to scratches or the like, such a head surface may rust. However, if high-purity pure iron is used, it can be maintained by carburizing the entire club head, and it is less likely to rust even with deep scratches. Since the convex portion 5 is provided on the golf club head 1, the strength of the head face portion 2 is improved, and the hand feeling when hitting the ball in the state of hitting the center point is excellent. In addition, since the depth of gravity (the distance from the leading edge to the horizontal direction of the center of gravity) is deep, the range of the sweet zone is wide. Since the convex portion 5 of the golf club head 1 reaches the rod bottom portion 6, its center of gravity is low and it is easy to pilling. The golf club head of this creation is suitable for a face angle of more than 2 5 °, 70. The following iron heads are especially suitable for wedge-shaped club heads with angles above 40 ° and 65 °, but they are also suitable for club heads of grass wood made of iron (F airway W 〇 ◦ d H ead ) or the utility head of the utility club. In addition, a material with a high specific gravity such as tungsten may be attached to the bottom of the club head of the present invention. Alternatively, a space may be provided inside the head face portion, and then a vibration absorbing material such as rubber or elastomer may be filled therein. 10 312XP/Creation Manual (Supplement)/94-08/94205925 M289074 [Simplified Schematic Description] Fig. 1 is a perspective view of the iron-type golf club head of the embodiment as seen from the rear.
