Abstract
Description
本發明是關於高爾夫球桿，且更具體而言是關於一種具有低位插鞘孔的高爾夫球桿頭。 The present invention relates to a golf club, and more particularly to a golf club head having a low-positioned insert hole.
許多高爾夫球員會訂製符合自身揮桿風格、高度或其他各種物理因素要求的球桿或球桿組。球桿的訂製一般而言包括對於高擊角及底角的調整，以確保球員處於擊球瞄準位置時桿面能夠正確對準。訂製高爾夫球桿頭時，通常會事先指定球員的訂製調整規格，使廠商能夠按照制定規格製造球桿。然而依此方式，不僅在球桿交貨前需要等待較長的製作時間，球員在收到桿頭後也無法對其規格進行調整。因此業界開始尋找更多能夠允許使用者在製造或裝配完成後的組裝程序中彎折桿面角度的方法。但桿面彎折越多，球桿越可能在彎折處發生材料變形，導致例如外鍍鉻等材料的桿頭上產生影響美觀的摺痕或對耐用性造成負面影響。 Many golfers customize clubs or club sets to suit their swing style, height, or various other physical factors. The customization of a club typically includes adjustments to the loft and lie angles to ensure that the clubface is aligned correctly when the player is at address. When customizing golf club heads, the player's custom adjustment specifications are usually specified in advance so that the manufacturer can build the club to the specified specifications. However, this method not only requires a long production time before the club is delivered, but also does not allow the player to adjust the specifications after receiving the clubhead. Therefore, the industry began to look for more ways to allow users to bend the clubface angle during the assembly process after manufacturing or assembly. However, the more the club face is bent, the more likely the club will experience material deformation at the bend, resulting in creases on the head of materials such as chromium plating that affect the appearance or have a negative impact on durability.
在製造時，通常是調整插鞘而對高爾夫球桿的桿面進行定向，藉此形成初始高擊角及底角，隨後再經由例如彎折等製造後調整手段設定最終高擊角及底角。隨著插鞘彎折增加，球桿會逐漸產生如應力斑痕等外觀缺陷及/或產生結構失效。例如，習知桿頭的製造後彎折調整範圍通常以約±2度為限，超過此限便可能出現應力斑痕或結構失效。因此業界實需一種使得高爾夫球桿頭能夠耐受製造後彎折而不產生實質應力斑痕或失 效的技術。 During manufacturing, the clubface of a golf club is usually oriented by adjusting the hosel to form an initial loft and lie angle, which are then set to a final loft and lie angle by post-manufacturing adjustments such as bending. As the hosel bend increases, the club will gradually develop cosmetic defects such as stress marks and/or structural failure. For example, it is known that the post-manufacturing bend adjustment range of the club head is usually limited to about ±2 degrees, exceeding which stress marks or structural failure may occur. Therefore, the industry really needs a technology that allows golf club heads to withstand post-manufacturing bending without causing actual stress marks or failure.
本發明提供一種具有較短插鞘及較低插鞘孔的鐵桿型高爾夫球桿頭。所述鐵桿型高爾夫球桿頭在維持或降低變形可能性及耐用度損失的前提下，提供針對高擊斜面及桿底的製造後可調整性，且能夠創造出可策略性設置而有助於改善性能的任意配置質量。 The present invention provides an iron-type golf club head with a shorter hosel and a lower hosel hole. The iron-type golf club head provides post-manufacturing adjustability for high-impact bevel and sole while maintaining or reducing the possibility of deformation and loss of durability, and can create arbitrary configuration qualities that can be strategically set to help improve performance.

本發明高爾夫球桿頭能夠在不增加甚至減少變形及耐用性損失的情況下，允許製造後的高擊斜面及桿底調整，且能夠創造出可策略性設置而提供性能優點的任意配置質量。在某些實施例中，鐵桿型高爾夫球桿頭包含與底部對立的頂沿、與踵端對立的趾端、與後端對立的桿面及插鞘。插鞘具有插鞘孔。插鞘孔形成於插鞘內，且貫穿插鞘全長並延伸進入桿頭本體。以下所述插鞘及加長的插鞘孔對高爾夫球桿頭的高擊斜面及底角賦予高達±4°的製造後可調整性。並且，此一設計可擴大應力分散面積，同時避免應力集中在彎折最甚的一側。如此達成的改良彎折能力有效降低失效風險，且有助於減少應力斑痕產生。 The golf club head of the present invention allows for post-manufacturing adjustment of the loft and sole without increasing or even decreasing deformation and loss of durability, and can create an arbitrary configuration mass that can be strategically placed to provide performance advantages. In certain embodiments, an iron-type golf club head includes a top edge opposite the sole, a toe end opposite the heel end, a club face opposite the rear end, and a hosel. The hosel has a hosel hole. The hosel hole is formed in the hosel and extends through the entire length of the hosel and into the body of the club head. The hosel and extended hosel hole described below provide post-manufacturing adjustability of the loft and sole angle of the golf club head up to ±4°. Furthermore, this design can expand the stress dispersion area while avoiding stress concentration on the side with the most severe bending. The improved bending capacity achieved in this way effectively reduces the risk of failure and helps reduce the generation of stress marks.
現請參照圖1至圖15，高爾夫球桿頭100的桿頭本體104具有與踵部112(或稱踵端112)對立的趾部108(或稱趾端108)。桿頭本體104亦包括與底部115(或稱底端115)對立的冠部(或稱頂沿)114。桿頭本體104的正面116(或稱前側116)設有面板120(或稱擊球面板120、或稱桿面120、或稱擊
球面120)，其具有擊球表面122。所述面板120與後部118(或稱後端118、或稱背面118、或稱後側118、或稱背側118)對立。所述面板120亦可具有多條溝槽125。

參照圖1A、圖1B及圖5A，且如上述，高爾夫球桿頭100亦具有位於踵部112且用於連接高爾夫球桿頭100與桿身(圖未示)的插鞘110。插鞘110具有延伸通過插鞘110中心的插鞘軸135(圖1B、圖5A、圖9)。插鞘110延伸在插鞘第一端142(或稱插鞘近端142)與插鞘第二端144(或稱插鞘遠端144)之間，所述遠近係相對於一桿頭本體104而論。插鞘110之插鞘近端142是在位於插鞘110外表面過渡至桿頭本體104(例如踵部112)之處的過渡平面145上，如圖5A所示。所述過渡平面145是與插鞘軸135垂直。
Referring to FIG. 1A , FIG. 1B and FIG. 5A , and as described above, the
插鞘110的插鞘孔150沿插鞘軸135延伸且用於容納連帶有握把的高爾夫球桿身。如圖所示，插鞘孔150具有位於桿頭本體104(具體而言為踵部112)內的插鞘孔第一端152(或插鞘孔近端152)，及位於插鞘110之插鞘遠端144的插鞘孔第二端154(或稱插鞘孔遠端154)。插鞘孔遠端154為開
放端且插鞘孔近端152為封閉端。插鞘孔近端152在插鞘孔頂端155處的桿頭本體104內形成插鞘孔150的下方邊界。插鞘孔近端152可容納一位於插鞘110與高爾夫球桿身之間的頂端配重塊156。如上所述，插鞘孔150延伸超越插鞘110之插鞘近端142並進入桿頭本體104。
The
插鞘110的插鞘長度L1是沿插鞘軸135自插鞘遠端144(或稱插鞘第二端144)測量至過渡平面145。在某些實施例中，插鞘長度L1含邊界值的範圍是介於0.75英吋與2.25英吋之間。在某些實施例中，插鞘長度L1含邊界值的範圍是介於1.0英吋與1.75英吋之間。例如，插鞘長度L1的範圍可介於1.0英吋與1.25英吋之間、1.25英吋與1.50英吋之間或介於1.50英吋與1.75英吋之間。
The hosel length L1 of the
插鞘孔150的插鞘孔長度L2是沿插鞘軸135自插鞘孔第一端152(或稱插鞘孔近端152)測量至插鞘孔第二端154(或稱插鞘孔遠端154)。在某些實施例中，插鞘孔長度L2含邊界值的範圍是介於1.0英吋與2.5英吋之間。在某些實施例中，插鞘孔長度L2含邊界值的範圍是介於1.3英吋與2.2英吋之間。例如，插鞘孔長度L2的範圍可介於1.3英吋與1.4英吋之間、1.4英吋與1.5英吋之間、1.5英吋與1.6英吋之間、1.6英吋與1.7英吋之間、1.7英吋與1.8英吋之間、1.8英吋與1.9英吋之間、1.9英吋與2.0英吋之間、2.0英吋與2.1英吋之間或介於2.1英吋與2.2英吋之間。
The sheath hole length L2 of the
依據本發明，插鞘長度L1是小於插鞘孔長度L2，以確保插鞘孔150延伸超過插鞘110並進入桿頭本體104。在許多實施例中，插鞘孔長度L2至少為插鞘長度L1的100%。在其他實施例中，插鞘孔長度L2可為插鞘長度L1的約100%至160%。例如，插鞘孔長度L2可為插鞘長度L1的約100%至110%、110%至120%、120%至130%、130%至140%、140%至150%或150%至160%。使插鞘孔150延伸進入桿頭本體104可減少踵部112的材料並減輕質
量，有利於桿頭100的製造後彎折並增加可任意配置的質量。
According to the present invention, the hosel length L1 is less than the hosel bore length L2 to ensure that the hosel bore 150 extends beyond the
桿頭100的構形對於插鞘孔150形狀有所影響。具體而言，桿頭100的踵趾過渡132可為拱形。隨著插鞘孔150繼續延伸進入桿頭100，插鞘軸135與踵趾過渡132聚合，減少兩者之間的桿頭材料量，並產生應力集中區域。為維持結構完整性，可經由使插鞘孔近端152具有適當形狀而達成在插鞘孔150與踵趾過渡132之間維持足夠的桿頭材料量的效果。在某些實施例中，插鞘孔150的插鞘孔頂端155是朝向插鞘孔近端152逐漸縮小。如圖9中可見，插鞘孔頂端155呈截頭圓錐形，插鞘孔遠端154直徑較大，插鞘孔近端152直徑較小，藉此使得踵趾過渡132處能夠維持足夠的結構完整性。
The configuration of the
插鞘孔150可具有多個相對於桿頭本體104位置各異的插鞘孔壁158。例如，可分別鄰近趾部108或踵部112側之插鞘孔壁158可稱為趾側內壁198及踵側內壁194。在許多實施例中，趾側內壁198及踵側內壁194可形成為連續的圓弧形狀。
The
趾側內壁198可與插鞘軸135夾設一趾側內壁角度196。踵側內壁194可與插鞘軸135夾設一踵側內壁角度192。該等內壁的傾斜配置在插鞘孔第一端152產生錐形效應。趾側內壁角度196含邊界值的範圍是介於2.5°與20°之間。在某些實施例中，趾側內壁角度196含邊界值的範圍是2.5°至5.0°、5.0°至7.5°、7.5°至10.0°、10.0°至12.5°、12.5°至15°、15°至17.5°或17.5°至20°。踵側內壁角度192含邊界值的範圍亦可為介於2.5°與20°之間。在某些實施例中，踵側內壁角度192含邊界值的範圍是介於2.5°至5.0°、5.0°至7.5°、7.5°至10.0°、10.0°至12.5°、12.5°至15°、15°至17.5°或17.5°至20°。
The toe
在許多實施例中，趾側內壁角度196與踵側內壁角度192相同。在其他替代實施例中，趾側內壁角度196與踵側內壁角度192不同。具體而言，踵側內壁角度192可大於趾側內壁角度196。具有不同角度的內壁
可構成非對稱形狀。
In many embodiments, the toe
參照圖1B、圖2及圖4，使插鞘孔150延伸進入桿頭本體104而增加的任意配置重量可設置於桿頭100他處，藉此將桿頭100重心240(或CG 240)移動至所需位置。重心240位置可相對於具有x軸202、y軸204及z軸206的座標系而定義。幾何中心210即是此具有x軸202、y軸204、z軸206的座標系的原點。x軸202(見圖1B及圖2)自趾部108延伸通過桿頭幾何中心210而至踵部112。x軸202以朝向趾部108為正向。y軸204(示於圖1B及圖4)自冠部114延伸通過桿頭幾何中心210而至底部115。y軸204以朝向冠部114為正向。自前視圖(或自面板120)觀之，y軸204垂直於x軸202。y軸204相對於插鞘軸135以一角度傾斜。z軸206(見圖2及圖4)自高爾夫球桿頭100面板120延伸通過幾何中心210而至後端118。z軸206以朝向面板120為正向。z軸206垂直於x軸202及y軸204。

另一項表明插鞘孔特徵的因素是插鞘孔總體積。插鞘孔總體積可相對於數條跨越桿頭100且平行於地面平面160的軸分為上方插鞘孔體積與下方插鞘孔體積而加以說明，如圖7及圖8所示。使插鞘孔150延伸進入桿頭本體104而低於特定參考平面的優點在於此舉能夠減輕整體球桿質量，產生可任意配置的質量，獲致性能優點，並確保插鞘110能夠耐受±4°彎折而不產生實質變形。
Another factor that characterizes the hosel bore is the overall hosel bore volume. The overall hosel bore volume can be described relative to a number of axes that span the
對上方插鞘孔體積及下方插鞘孔體積進行量化時，是以下文將詳述的各軸做為參照。第一軸165(以下稱為「頂部連接插鞘軸」165)跨越插鞘110最頂緣，且在桿頭處於擊球瞄準位置時是與地面平面160平行。插鞘高度166是指自地面平面160至頂部連接插鞘軸165的距離。在某些實施例中，插鞘高度166含邊界值的範圍是介於1.5英吋與2.75英吋之間。在許多實施例中，插鞘高度166含邊界值的範圍是介於1.75英吋與2.25英吋之間。
例如，插鞘高度166含邊界值的範圍是介於1.75英吋與1.85英吋之間、1.85英吋與1.95英吋之間、1.95英吋與2.05英吋之間、2.05英吋與2.15英吋之間或介於2.15英吋與2.25英吋之間。
The upper hosel bore volume and the lower hosel bore volume are quantified with reference to the axes described in detail below. A first axis 165 (hereinafter referred to as the "top hosel axis" 165) spans the top edge of the
第二軸170(以下稱為「插鞘連接本體軸」170)與地面平面160平行且跨越插鞘110與桿頭本體104會合之處。插鞘孔體積特徵並可利用位於插鞘連接本體軸170上方或下方的總體積百分比進行說明。具體而言，插鞘孔體積的一部分(以下稱插鞘孔體積部分172)可位於插鞘連接本體軸170的下方。在某些實施例中，位於插鞘連接本體軸170下方的插鞘孔體積部分172含邊界值的範圍是介於插鞘孔體積的5%與40%之間。在許多實施例中，位於插鞘連接本體軸170下方的插鞘孔體積部分172含邊界值的範圍是插鞘孔體積的5%與30%之間。在某些實施例中，位於插鞘連接本體軸170下方的插鞘孔體積部分172為插鞘孔體積的5%-10%、10%-15%、15%-20%或20%-25%。
The second axis 170 (hereinafter referred to as the "hosel connection body axis" 170) is parallel to the
另一種測量標準是插鞘與本體比率，此比率是定義為位於插鞘連接本體軸170上方的插鞘孔體積部分與位於插鞘連接本體軸170下方的插鞘孔體積部分172，此兩者之間的比率。在某些實施例中，插鞘與本體比率H1：H2是約1.5：0.025至1.5：0.25。
Another measurement standard is the hosel-to-body ratio, which is defined as the ratio between the hosel bore volume portion located above the hosel-to-
第三軸175(以下稱為「中線軸」175)與地面平面160平行且跨越桿頭本體104的幾何中間部分。插鞘孔體積部分176可位於中線軸175下方。在某些實施例中，位於中線軸175下方的插鞘孔體積部分176含邊界值的範圍是插鞘孔體積的1%與20%之間。在許多實施例中，位於中線軸175下方的插鞘孔體積部分176含邊界值的範圍是插鞘孔體積的1%與15%之間。在某些實施例中，位於中線軸175下方的插鞘孔體積部分176是插鞘孔體積的1%-5%，5%-10%或10%-15%。
A third axis 175 (hereinafter referred to as "centerline axis" 175) is parallel to the
使延伸插鞘孔150進入桿頭本體104能夠降低CG 240，減輕桿頭質量，創造可任意配置的重量，並可配合縮短插鞘的設計，進一步減輕質量。此外，將插鞘孔150設置於桿頭本體104內部低位可確保插鞘110彎折點出現在壁厚可耐受較高應力之處。因此，降低插鞘孔150位置可使桿頭100在高擊斜面及桿底調整過程中彎折至更大角度而不致嚴重受損或顯著變形。
Extending the
第四軸180(以下稱為「底部連接插鞘軸」180)在桿頭100處於擊球瞄準位置時是與地面平面160平行且跨越插鞘孔150的最底部邊緣。插鞘孔高度182可定義為地面平面160至底部連接插鞘軸180的距離。在某些實施例中，插鞘孔高度182含邊界值的範圍是介於0.25英吋與1.0英吋之間。在許多實施例中，插鞘孔高度182含邊界值的範圍是介於0.25英吋與0.75英吋之間。在某些實施例中，插鞘孔高度182的範圍是介於0.25英吋與0.35英吋之間、0.35英吋與0.45英吋之間、0.45英吋與0.55英吋之間、0.55英吋與0.65英吋之間或介於0.65英吋與0.75英吋之間。
A fourth axis 180 (hereinafter referred to as "bottom connection hosel axis" 180) is parallel to the
插鞘與插孔比率可定義為插鞘高度166與插鞘孔高度182之間的比率。在某些實施例中，插鞘與插孔比率是1.2：1.1至1.7：1.0。在許多實施例中，插鞘與插孔比率是1.25：1.15至1：6：1.1。插鞘孔150較插鞘110更長且延伸進入桿頭本體104。此插鞘孔配置減輕桿頭本體104上方部分126的質量並降低整體CG 240，創造可供應用於實現配重優點的任意配置質量。延伸的插鞘孔150使得彎折發生於桿頭本體更深處，有助於增加應力分布的表面積。由於插鞘與本體連接點及踵部112的壁面隨著插鞘孔150向下延伸深入桿頭本體104而減薄，因此插鞘110在彎折時不會產生顯著的應力斑痕。低位插鞘孔設計可維持對於高擊斜面及桿底的製造後調整能力，同時減少顯著應力斑痕並創造可用於提升桿頭性能的任意配置質量。
The hosel to hub ratio may be defined as the ratio between the
再者，由於插鞘孔150的部分延伸進入本體104(或踵部112)，頂端配重塊156的一部分可部分或全部位在桿頭本體104內，而頂端配重塊156的其餘部分則可位在插鞘110內。頂端配重塊156的重量範圍可介於0克與18克之間。在某些實施例中，頂端配重塊156的重量可為0克(在無頂端配重塊的實施例中)，1克、2克、3克、4克、5克、6克、7克、8克、9克、10克、11克、12克、13克、14克、15克、16克、17克或18克。在某些實施例中，頂端配重塊156的範圍是介於0克與9克之間。頂端配重塊156可包含與桿頭本體104材料不同的材料。頂端配重塊156可採用與趾部配重塊157相同或不同的材料製作，且因此包含高密度材料，例如鎢或任何其他金屬或金屬合金材料。
Furthermore, since a portion of the
插鞘壁厚度影響插鞘經歷製造後彎折並耐受伴隨應力的能力。參照圖5A及圖9-12，插鞘孔150具有插鞘孔壁158。插鞘孔壁158長度L2上的不同區域各具有相關厚度T1、T2、T3，所述厚度是自插鞘孔150內表面測量至插鞘110外表面及/或至踵部112。插鞘孔壁158的厚度大致上是自插鞘孔150之插鞘孔近端152向插鞘孔150之插鞘孔遠端154縮減。亦即，插鞘孔壁158在插鞘孔近端152具有厚度最大的第一壁厚T1，在插鞘孔遠端154具有厚度最小的第二厚度T2，且位於插鞘孔近端152與插鞘孔遠端154之間的插鞘孔壁158具有小於第一厚度T1且大於第二厚度T2的第三厚度T3。換言之，插鞘孔壁158可分為第一區186、第二區188及第三區190。
The thickness of the hosel wall affects the hosel's ability to undergo post-manufacturing bending and withstand the attendant stresses. Referring to FIG. 5A and FIGS. 9-12 , the hosel bore 150 has a hosel bore wall 158. Different regions along the length L2 of the hosel bore wall 158 each have an associated thickness T1, T2, T3, and the thickness is measured from the inner surface of the hosel bore 150 to the outer surface of the
於圖5A中係以虛線標示第一區186、第二區188及第三區190。所述區域僅為舉例，亦可以其他方式劃分。第一區186係用以至少部分容納頂端配重塊156。在圖示實施例中，整個頂端配重塊156都是位在第一區186之內。在某些實施例中，頂端配重塊156可位於第一區186及第三區190兩者之中。第一區186具有第一壁厚T1，第二區188具有第二壁厚T2，第
三區190具有第三壁厚T3。
In FIG. 5A , the
基於兩個理由，插鞘孔壁158在第一區186的厚度T1並不一致。其一，插鞘孔壁158的至少一部分可相對於插鞘軸135逐漸變細，其次，插鞘孔壁158的一部分是由呈彎弧構形的踵部112所形成。以下將就此等理由詳述。插鞘孔壁158頂側的第一壁厚T1大於插鞘孔壁158的其餘部分。
The thickness T1 of the hosel bore wall 158 in the
第一壁厚T1的範圍可自約0.05英吋至約0.50英吋。第二壁厚T2的範圍可自約0.03英吋至約0.3英吋。第三壁厚T3的範圍可自約0.02英吋至約0.25英吋。第一區186、第二區188及第三區190的插鞘孔壁厚T1、T2、T3可對應於桿頭本體104的材料種類。
The first wall thickness T1 may range from about 0.05 inches to about 0.50 inches. The second wall thickness T2 may range from about 0.03 inches to about 0.3 inches. The third wall thickness T3 may range from about 0.02 inches to about 0.25 inches. The wall thicknesses T1, T2, and T3 of the hosel holes of the
插鞘孔壁158在第一區186、第二區188及第三區190中的個別厚度T1、T2、T3詳見圖5A及圖9-12。首先，如圖5A所示，插鞘孔壁158在第一區186之踵部112一側的厚度T1與自插鞘110過渡至踵部112的外表面對應。因此，隨著踵側外表面自插鞘110外表面過渡至踵部112，插鞘孔壁158在第一區186中的厚度T1縮減。換言之，插鞘孔壁158的厚度T1在踵部112一側上介於第一區186與第三區190之間達到最低位置，且在插鞘孔150之插鞘孔第一端152呈現最小厚度。此外，在踵部112一側上，插鞘孔壁158的厚度T1自第一區186與第三區190之間的位置沿朝向插鞘孔150之插鞘孔第一端152的方向縮減。且如圖所示，第一區186插鞘孔壁158是相對於插鞘軸135漸成錐狀。插鞘孔壁158與插鞘軸135之間的踵側內壁角度192可處於約2.5°至5.0°、5.0°至7.5°、7.5°至10.0°、10.0°至12.5°、12.5°至15°、15°至17.5°或17.5°至20°的範圍內。
The individual thicknesses T1, T2, and T3 of the hosel hole wall 158 in the
再者，參照圖10至圖12，插鞘孔150內部的第一區186、第二區188及第三區190分別具有第一維度(例如第一孔徑224、第二孔徑226、第三孔徑228)，且插鞘110與踵部112的外表面具有第二維度230。插鞘孔150
的第一孔徑224、第二孔徑226、第三孔徑228大致是自插鞘孔150之插鞘孔近端152向插鞘孔150遠端縮小。亦即，插鞘孔150在插鞘孔近端152具有直徑最大的第一孔徑224，在插鞘孔遠端154具有直徑最小的第二孔徑226，且在插鞘孔遠端154與插鞘孔近端152之間的插鞘孔150具有小於第一孔徑224且大於第二孔徑226的第三孔徑228。且與此對應，第一區186的第一孔徑224大致上是自插鞘孔近端152沿朝向插鞘孔第二端154的方向增加。第二維度230大致上是在第二區188、第三區190(且圍繞由軸242、244所定義的時鐘)中維持不變，但由於第一區186呈矩形，第二維度230在第一區186中並非維持不變(因為相對於軸242、244所構成時鐘呈現變化厚度，如上所述)。換言之，第一區186具有第一孔徑224及可變第二維度230，第二區188具有第二孔徑226及固定第二維度230，第三區190具有第三孔徑228及固定第二維度230，與第二區188的固定第二維度230相同。
Furthermore, referring to FIGS. 10 to 12 , the
第一孔徑224的範圍可為約0.05英吋至約0.50英吋。第二孔徑226的範圍可為約0.25英吋至約0.75英吋。第三孔徑228的範圍可為約0.10英吋至約0.60英吋。第二維度230在第一區186中的範圍可自約0.50英吋至約1.0英吋，且第二維度230在第二、第三兩區188、190的範圍可自約0.25英吋至約0.85英吋。據此，第一孔徑224可為第一區186最大第二維度230的約5%至約50%，且為第一區186最小第二維度230的約20%至約90%。第二孔徑226可為第二維度230的約25%至約90%。第三孔徑228可為第二維度230的約25%至約90%。第一孔徑224、第二孔徑226、第三孔徑228及第二維度230係至少部分依據桿頭本體104材料的種類而決定。
The
如圖10至圖12所示，在上述實施例中，插鞘110與插鞘孔150皆具有圓形截面。亦即，第二區188、第三區190與插鞘孔150具有圓形截面。在其他實施例中，插鞘110可具有不同形狀的截面，且因此第一區186及第
二區188的截面可呈現不同形狀。例如，插鞘110(及其第二區188與第三區190)可具有卵形或橢圓形截面。此種修改會對相對插鞘孔壁厚T1、T2、T3及第二區188與第三區190的第二維度230造成改變。
As shown in FIGS. 10 to 12 , in the above-mentioned embodiment, the
在替代實施例中，如圖14及圖15所示，插鞘孔可形成為連續狀，在桿頭本體內形成封閉空腔。如圖14中實施例所示，空腔可部分延伸進入桿頭，且可形成為凹背或刀背式鐵桿型桿頭的一部分，或可用於短切桿、功能短切桿或推球桿。如圖15中實施例所示，空腔可延伸貫穿整個桿頭本體，形成具有中空本體的鐵桿型桿頭。於上述實施例中，插鞘孔可向空腔開放，因而使得插鞘孔與空腔共同形成單一空間。在其他實施例中，插鞘孔及空腔可為截開一部分或整片壁面。 In alternative embodiments, as shown in Figures 14 and 15, the hosel hole can be formed in a continuous shape to form a closed cavity in the club head body. As shown in the embodiment in Figure 14, the cavity can partially extend into the club head and can be formed as part of a concave back or blade back iron type club head, or can be used for a short chipping club, a functional short chipping club or a putting club. As shown in the embodiment in Figure 15, the cavity can extend through the entire club head body to form an iron type club head with a hollow body. In the above embodiments, the hosel hole can be open to the cavity, so that the hosel hole and the cavity together form a single space. In other embodiments, the hosel hole and the cavity can be a cut-off part or the entire wall.
圖14實施例中桿頭的部分空腔延伸而對齊擊球面的最近踵部邊緣。在其他實施例中，所述部分空腔可延伸至擊球面邊緣朝向踵部或趾部的一點。空腔的形狀及大小可經設計而在插鞘彎折時與擊球時產生最佳應力分布。 In the embodiment of FIG. 14 , a portion of the cavity of the club head extends to align with the nearest heel edge of the striking face. In other embodiments, the portion of the cavity may extend to a point on the edge of the striking face toward the heel or toe. The shape and size of the cavity may be designed to produce optimal stress distribution when the hosel is bent and when the ball is struck.
圖中所示圍繞插鞘孔及封閉空腔的壁厚通體維持一致。但在其他實施例中，此等壁體可在提供所需結構強度及剛性的條件下具有變化厚度，例如形成錐狀或包含加厚區域，以改善可製造性或將彎折的發生限定在所需區域。 The wall thickness surrounding the insert hole and the closed cavity is shown to be uniform throughout. However, in other embodiments, such walls may have varying thicknesses while providing the desired structural strength and rigidity, such as being tapered or including thickened areas to improve manufacturability or to limit the occurrence of bending to a desired area.
2.優點2. Advantages
如上所述，使插鞘110相對於桿頭本體104彎折(經由錘擊或類似方式)即構成對於高擊角及底角的調整。透過插鞘110及插鞘孔150的適當位置與配置，可將此一過程中產生的應力分散到插鞘110上更大的長度範圍，同時降低作用於桿頭本體104其他區域上的應力。如圖1A及圖5A所示，插鞘孔近端152構成插鞘孔150在插鞘110上的最低位置。在彎折過程中，應
力集中於插鞘孔近端152的角落。藉由降低插鞘孔近端152出現在插鞘110內的位置，可將應力分散到更大面積的壁面，從而降低每一個別位置所承受的最大應力。但桿頭100仍保有容許高擊斜面及桿底調整多達±4度的能力。
As described above, bending the
亦即，藉由在第二、第三兩區188、190中維持不變壁厚T2、T3且將插鞘孔150之插鞘孔近端152設置於桿頭本體104內部，可使應力沿著插鞘長度L1達成更均勻的分布，如此在理論上應可降低局部應力集中並有助於達成更佳彎折效果。參照圖10，為說明插鞘110的厚度T1、T2、T3，可將插鞘孔150及插鞘孔壁158比擬於類比式時鐘，其中x軸222延伸於12點與6點之間，z軸220延伸於3點與9點之間。如圖所示，上述時鐘的x軸222平行於延伸通過高爾夫球桿頭100幾何中心210的x軸202且與之錯位。在圖示實施例中，在第一區186，插鞘孔壁158的厚度T1在12點與3點之間最大，因為此處是桿頭本體104形成插鞘孔壁158的部位。再者，雖未示於圖10至圖12，插鞘孔壁158的厚度T1可大致自第一區186與第三區190之間的位置沿朝向插鞘孔150之插鞘孔第一端152和桿頭本體104在4點與7點之間的區域的方向減少，因為此處大致是自插鞘110過渡至踵部112的外表面所在區域。如圖所示，在圖11及圖12中，厚度T2及T3大致在時鐘周圍維持一致，厚度T3小於厚度T2。
That is, by maintaining constant wall thicknesses T2 and T3 in the second and
圖4顯示一垂直平面250。垂直平面250是一個在桿頭本體104處於擊球準備位置時大致與地面表面垂直的假想平面。垂直平面250與高爾夫球桿頭100前沿254(或稱最前緣254)相切且與地面平面160垂直。插鞘軸135與此垂直平面250夾設一角度。換言之，插鞘軸135是相對於垂直平面250傾斜。插鞘軸135與垂直平面250夾設第一角度260。第一角度260代表插鞘tilt。在圖示實施例中，插鞘傾向(或第一角度260)約為0.25度至約20度，且具體而言為約至少5.0度。插鞘傾斜的走向是使得插鞘軸135以遠離垂直平面
250的方向延伸。換言之，插鞘軸135是配置成在低於地面平面的一個假想位置上與垂直平面250相交。由於插鞘相對於垂直平面250的傾向或負向插鞘傾斜，球員在擊球準備位置時得以將其雙手放置於球的後方(或朝向球員的跟隨腳或後方腳)。應知處於擊球準備位置時，桿頭本體104會與地面接觸。具體而言，是底部115(或底部115的一部分)與地面接觸。
FIG. 4 shows a
參照圖1B，當桿頭100處於擊球準備位置，插鞘軸135方向與地面平面160夾設一角度。換言之，插鞘軸135相對於地面平面160傾斜。插鞘軸135與垂直平面250夾設一第二角度262。第二角度262代表底角。在圖示實施例中，底角262(或稱第二角度)約為31度至約37度，具體而言約為至少32度。底角的走向使得插鞘軸135以遠離地面平面160的方向延伸。
Referring to FIG. 1B , when the
為進一步說明本發明的創新，可將x軸202與z軸206對應於圖10至圖12中類比式時鐘上的數字。z軸206延伸在12點(通過面板120的「12」)與6點鐘(通過後端118的「6」)之間，x軸202延伸在3點(通過趾端108的「3」)與9點(通過踵部112一端的「9」)之間，如上所述。
To further illustrate the innovation of the present invention, the
在圖示實施例中，重心240位置可以幾何中心210為基準測量。重心240可沿x軸202相對於幾何中心210測量，標記為CGx。重心240亦可沿y軸204相對於幾何中心210測量，標記為CGy。重心240並可沿z軸206相對於幾何中心210測量，標記為CGz。增加或減少沿x軸202的距離可使重心240朝向趾部108或踵部112移動。減少沿y軸204的距離可降低重心240。增加沿z軸206的距離可使重心240向後移動。在其他實施例範例中，可以高爾夫球桿頭100前沿254(或高爾夫球桿頭100最前端位置)為重心240位置測量基準。
In the illustrated embodiment, the position of the center of
插鞘孔150的位置與配置使得高爾夫球桿頭100的CG 240可較前案高爾夫球桿頭降低至理想高度，詳情說明如下。
The location and configuration of the
在某些實施例中，重心240可大致與幾何中心210沿x軸202對齊(亦即CGx大致為零)。在其他實施例中，沿x軸202測量時，CGx可位於與幾何中心210相距約-0.10英吋至約0.10英吋之處。本發明鐵桿型高爾夫球桿頭100並具有在y軸204上與幾何中心210相距約0.10英吋至約0.75英吋的CGy。在圖示實施例中，CGy位於幾何中心210與底部115之間。由於插鞘110具有如此的位置與配置，重心240較習知鐵桿型高爾夫球桿頭低約0.040英吋(見圖9A)。
In some embodiments, the center of
具體參照圖4，高爾夫球桿頭100還具有一高擊斜面平面268。高擊斜面平面268與擊球表面122的幾何中心210相切。擊球面外周可位於擊球表面122的外緣上。此外，高度是在擊球面外周靠近頂沿114的頂端位置與擊球面外周頂端靠近底部115的底端位置之間平行於高擊斜面平面268測量而得。

復參照圖7，高爾夫球桿頭100具有一衝擊力線270。衝擊力線270是一條力線，其延伸通過受面板120擊球表面122所擊打高爾夫球的中心。衝擊力線270的走向是與面板120垂直，且具體而言是與擊球表面122垂直。在某些實施例中，衝擊力線270可延伸通過擊球表面122的幾何中心210。
Referring again to FIG. 7 , the
在圖示實施例中，高爾夫球桿頭100可具有圍繞x軸202的慣性矩Ixx(亦稱為頂底慣性矩)，及圍繞y軸204的慣性矩Iyy(亦稱為踵趾慣性矩)。於某些實施例範例中，基於桿頭設計人員可利用的任意配置質量多寡，提高或最大化頂底慣性矩Ixx與踵趾慣性矩Iyy。高爾夫球桿頭100的頂底慣性矩Ixx可為約50g．in2至約120g．in2，且具體而言為約60g．in2至約110g．in2。高爾夫球桿頭100的踵趾慣性矩Iyy為約300g．in2至約450g．in2，且具體而言為約325g．in2至約425g．in2。
In the illustrated embodiment, the
除插鞘孔150關係位置之外，慣性矩Ixx、Iyy及CG 240也取
決於高爾夫球桿頭100的其他特徵。構成桿頭本體104、面板120、趾部配重塊157及頂端配重塊156的材料對於高爾夫球桿頭100的質量分布有所影響。因此，高爾夫球桿頭100的慣性矩Ixx、Iyy及重心CG 240亦受材料密度影響。此外，材料為高爾夫球桿頭100提供所需的強度與彈性。高爾夫球桿頭100包含一或多、二或多、三或多或四或多種材料。在某些實施例中，所述材料可為第一密度、第二密度、第三密度、第四密度、第五密度或第六密度。
In addition to the relative position of the
在某些實施例中，面板120可包含具有第一密度的第一材料。桿頭本體104可包含具有第二密度的第二材料。在圖示實施例中，面板120與桿頭本體104可採用相同材料(因此具有相同密度)。
In some embodiments, the
桿頭本體104可包含例如鋼、鋼合金或任何其他適合材料。在某些實施例中，本體104所用材料可與面板120所用材料的密度不同。本體104材料的密度範圍可介於每立方公分7.70與8.10克之間(下書為「g/cc」)。在某些實施例中，本體材料的密度可為7.70g/cc、7.75g/cc、7.80g/cc、7.85g/cc、7.90g/cc、7.95g/cc、8.05g/cc或8.10g/cc。

桿頭100的材料可具有依洛氏量表測定的硬度(HRC)。在許多實施例中，材料硬度與插鞘110的壁厚T1、T2、T3及第一孔徑224、第二孔徑226、第三孔徑228有關。以較低硬度材料製作的桿頭必須具備較大厚度區域才能夠減少應力彎折的出現。為維持彎折插鞘所需的力度，以較高硬度材料製作的高爾夫球桿頭所需的插鞘壁厚小於以較低硬度材料製作的高爾夫球桿頭。原因在於越硬的材料需要越大的力量才能使之變形。因此宜透過依據材料特性的需要對壁厚進行修改，使得彎折插鞘所需的力量近乎一致，藉此建立一套統一的組裝程序。下文範例V將就材料硬度與插鞘壁厚之間的關係詳細說明。

根據本發明插鞘110及插鞘孔150位置及配置與習知鐵桿型高爾夫球桿頭(其中之一為圖6A所示者)的對照可知，其插鞘長度L1較習知鐵桿型高爾夫球桿頭短約0.300英吋。並且，由於插鞘長度L1減少，加上用於容納頂端配重塊156的第一區186呈現錐形，使得高爾夫球桿頭100的整體質量減輕約6克。CG 240在上述差異的作用下產生下移。因此，如上所述，CG 240在y軸204上的位置較習知鐵桿型高爾夫球桿頭低約0.040英吋。

範例I-本發明桿頭實施例與對照桿頭的質量特性比較 Example I-Comparison of quality characteristics of the club head embodiment of the present invention and the reference club head
範例I針對採用一般插鞘孔構形且分別設有和未設外部槽口的傳統鐵桿型高爾夫球桿頭實施例，與兩種採用本發明插鞘孔構形且不具有外部槽口的桿頭實施例進行比較。具體而言，範例1探討傳統桿頭與上述低位插鞘構形桿頭實施例在CG及MOI上的差異，如表1所示。 Example 1 compares a conventional iron-type golf club head embodiment with a general insert hole configuration and with and without an external notch, respectively, and two club head embodiments with the insert hole configuration of the present invention and without an external notch. Specifically, Example 1 explores the differences in CG and MOI between the conventional club head and the above-mentioned low insert hole configuration club head embodiment, as shown in Table 1.
在此用於比較的傳統鐵桿型高爾夫球桿頭XX如圖6A所示，其採用一般插鞘構形且具有插鞘槽口(以下稱為「對照桿頭1」)。而用於比較的本發明範例實施例是不具槽口且採用如上述低位插鞘孔構形及孔
壁縮窄結構的鐵桿型高爾夫球桿頭。
The conventional iron-type golf club head XX used for comparison is shown in FIG. 6A , which adopts a general insert sheath configuration and has an insert sheath notch (hereinafter referred to as “
對照桿頭1與範例桿頭1具有相仿的本體結構、體積及高擊角。表1以直接比較方式顯示插鞘尺寸、CG、MOI及桿頭質量方面的差異。
The control clubhead 1 has a similar body structure, volume, and high attack angle as the
如表1所示，範例桿頭1的桿頭本體與對照桿頭1及對照桿頭2的本體極為相似。在外部插鞘與頂沿會合點到地面平面的距離方面，範例桿頭1與對照桿頭1相同，且與對照桿頭2相近。此外，就地面平面與中線軸之間的距離而言，範例桿頭1與對照桿頭1相同，且與對照桿頭2相仿。再者，關於插鞘上方區域及中間區域的插鞘壁厚，範例桿頭1與對照桿頭1相同，且與對照桿頭2相近。
As shown in Table 1, the club body of
表I顯示範例桿頭1的插鞘孔體積較對照桿頭1大10.5%，較對照桿頭2大40.7%。對照桿頭1及對照桿頭2兩者的整個插鞘孔體積皆位於中線軸以上，而範例桿頭1的插鞘孔體積僅有90%高於中線軸，其餘部分處於中線軸下方並延伸進入桿頭內部。
Table I shows that the hosel volume of Example 1 is 10.5% larger than that of
雖然範例桿頭1的插鞘孔體積大於對照桿頭1及對照桿頭2兩者，但範例桿頭1相對於地面平面的外部插鞘高度遠低於對照桿頭1及對照桿頭2。具體而言，範例桿頭1的外部插鞘高度較對照桿頭1插鞘低8.6%，較對照桿頭2插鞘低8.8%。
Although the hosel hole volume of
在範例桿頭1上，地面平面與插鞘孔底之間的距離遠小於對照桿頭1及對照桿頭2。具體而言，範例桿頭1插鞘孔下緣距離地面平面的高度較對照桿頭1低57.1%，較對照桿頭2低65.1%。此一比較結果明確顯示範例桿頭1插鞘孔的延長程度。具體而言，範例桿頭1的外部插鞘僅較對照桿頭1及對照桿頭2低8.6%-8.8%，但內部插鞘孔下向延伸程度遠大於此，因此其下緣較對照桿頭1及對照桿頭2低57.1%-65.1%。
On
由於插鞘孔向下延伸，範例桿頭1在桿頭踵側的材料減少，因此具有更多能夠策略性設置於桿頭他處的可任意配置質量。如表1所示，
範例桿頭1的桿頭質量與對照桿頭1相等，而較對照桿頭2輕5g。如此減輕桿頭踵側質量並改置於他處的結果是可使CG朝向趾端且向下移動。範例桿頭1的CG較對照桿頭1下移0.038英吋，而較對照桿頭2下移0.052英吋。範例桿頭1的CG相較於對照桿頭1向趾部移動0.107英吋，相較於對照桿頭2為0.023英吋。
Because the hosel hole extends downward,
申請人並發現範例桿頭1與對照桿頭1及對照桿頭2的MOI範圍相當。具體而言，範例桿頭1在x、y、z三個方向上的MOI均低於對照桿頭1，而在x、y、z三個方向上的MOI均高於對照桿頭2。MOI低於對照桿頭1的原因在於其桿頭踵側的質量減輕。雖然MOI通常以高為佳，但申請人發現CG下移對於球員表現的貢獻可能高於MOI增加。具體而言，根據測試結果，即使在MOI減少的情況下，透過移動CG仍可達到維持或改善統計區及準確度等性能特徵的效果。因此，在總體上維持MOI加上使CG向下移動，可在性能方面產生助益。

範例II-本發明實施例桿頭與對照桿頭在彎折時的材料變形量化比較 Example II - Quantitative comparison of material deformation of the club head of the embodiment of the present invention and the reference club head during bending
桿頭遭受強制彎折時，彎折位置通常會因受力產生材料變形而出現顯著斑痕。在此針對範例球桿與標準球桿進行分析並以量化回饋方式記錄其材料變形量。將多款球桿插鞘自其中性起始位置強制彎折2°至4°。若桿頭無法在不產生顯著變形的條件下彎折至所需角度，則評為「-」。若桿頭能夠彎折至所需角度且不產生顯著變形，則評為「+」。範例桿頭與標準桿頭均以此方式測量其上揚與下壓底角調整以及開放與封閉高擊斜面調整。下方表II詳示施加的彎折程度與因而產生的變形評比結果。 When a clubhead is subjected to a forced bend, the bend will usually show a noticeable mark due to the material deformation caused by the force. Here, sample and standard clubs are analyzed and the amount of material deformation is recorded in a quantitative feedback form. The hosels of various clubs are forced to bend 2° to 4° from their neutral starting position. If the clubhead cannot bend to the required angle without significant deformation, it is rated "-". If the clubhead can bend to the required angle without significant deformation, it is rated "+". Both the sample and standard clubheads are measured in this way for their lead and depression lie angle adjustments and open and closed loft adjustments. Table II below details the degree of bend applied and the resulting deformation evaluation results.
標準桿頭包含具有插鞘、趾部、上方部分與下方部分的本體、插鞘、用於連接高爾夫桿頭與桿身的插鞘孔以及位於本體踵側插鞘上的槽口。範例桿頭包含向下深入本體的插鞘孔及長度短於標準球桿的插 鞘。且範例桿頭在踵部或周圍區域未設有任何槽口或挖除結構。除此之外兩種桿頭的元件、尺寸及結構一概相同。 The standard club head includes a body with a hosel, a toe, an upper portion and a lower portion, a hosel, a hosel hole for connecting the golf club head to the shaft, and a notch on the hosel on the heel side of the body. The example club head includes a hosel hole that goes down into the body and a hosel that is shorter than the standard club. The example club head does not have any notches or cutouts on the heel or surrounding area. Other than that, the components, dimensions and structures of the two club heads are the same.
依據上述尺度評估因強迫彎折而產生的顯著變形斑痕或變色情形。彎折角度的些微變化是出於彎折過程中的人為誤差，有鑑於製造後桿頭的底角彎折不必十分精確，此等變化可逕予忽略。如圖所示，範例桿頭與標準桿頭能夠達成的彎折角度相當，但受測的四款標準桿頭樣本中有三款因彎折出現顯著變形。 The above scale is used to evaluate the significant deformation marks or discoloration caused by forced bending. Slight changes in the bending angle are due to human errors in the bending process. Since the bottom angle bend of the club head does not need to be very precise after manufacturing, such changes can be ignored. As shown in the figure, the sample club head and the standard club head can achieve the same bending angle, but three of the four standard club head samples tested have significant deformation due to bending.
範例III-插鞘處對所施力量反應的有限元素分析比較 Example III - Finite element analysis comparison of the sheath's response to applied forces
針對標準高爾夫球桿頭與範例高爾夫球桿頭進行彎折處應力值的比較。標準高爾夫球桿頭具有冠部、底部、桿面、後部、插鞘及插鞘孔。範例高爾夫球桿頭同樣具有上述結構但插鞘較短且插鞘孔較低。兩種高爾夫球桿頭在除卻插鞘及插鞘孔以外的所有尺寸及特徵方面完全相同。 Comparison of stress values at the bend between a standard golf club head and a sample golf club head. The standard golf club head has a crown, sole, clubface, rear, hosel, and hosel hole. The sample golf club head has the same structure but with a shorter hosel and a lower hosel hole. The two golf club heads are identical in all dimensions and features except for the hosel and hosel hole.
各款桿頭插鞘在強迫彎折或製造後彎折過程中產生應力的情況可透過有限元素法建模分析。對各款桿頭施加同樣的理論力量。應知沿著插鞘產生的大量應力是桿頭在所施力量的作用下發生物理性彎折的原因。但此一應力宜分散於整個插鞘，而非集中於特定位置。插鞘上應力高於周遭區域之處通常容易出現顯著材料變形。若桿頭在整個插鞘上出現大 量應力，但並未有任何可明確區分的應力集中位置，則通常不會在受到彎折時產生上述應力斑痕。否則顯著變形不僅破壞美觀，亦可能影響插鞘於該處的結構完整性，。 The stresses generated in the hosel of various club heads during forced bending or post-manufacturing bending can be modeled and analyzed using the finite element method. The same theoretical force is applied to each club head. It should be noted that the large amount of stress generated along the hosel is the reason why the club head will bend biologically under the action of the applied force. However, this stress should be distributed throughout the hosel rather than concentrated in a specific location. Places on the hosel where the stress is higher than the surrounding area are usually prone to significant material deformation. If the club head has a large amount of stress throughout the hosel, but there is no clearly distinguishable stress concentration location, it will usually not produce the above-mentioned stress marks when it is bent. Otherwise, significant deformation will not only destroy the aesthetics, but may also affect the structural integrity of the hosel at that location.
如圖5B至圖5D所示，具有低位插鞘孔的範例高爾夫球桿頭在整個插鞘上出現的最大應力與不具有低位插鞘孔的標準高爾夫球桿頭相仿。並且，如圖5A至圖5D所示，範例高爾夫球桿頭上的應力分布於插鞘各處，相較於標準高爾夫球桿頭並無較獨立的高應力區域。標準高爾夫球桿頭的應力集中區域出現在整個插鞘下端，如圖6B至圖6D所示。此一應力集中區域表示標準高爾夫球桿頭在實際承受建模力時，例如在製造後彎折的過程中，很可能於該處產生變形。 As shown in Figures 5B to 5D, the maximum stress on the entire hosel of the example golf club head with a low hosel hole is similar to that of the standard golf club head without a low hosel hole. Moreover, as shown in Figures 5A to 5D, the stress on the example golf club head is distributed throughout the hosel, and there is no independent high stress area compared to the standard golf club head. The stress concentration area of the standard golf club head appears at the lower end of the hosel, as shown in Figures 6B to 6D. This stress concentration area indicates that when the standard golf club head is actually subjected to the modeling force, such as during the bending process after manufacturing, it is likely to deform there.
如上所述，插鞘孔較低的範例高爾夫球桿頭並未出現任何高度獨立的應力集中區域。雖然兩款桿頭承受的最大應力大致相同，但範例高爾夫球桿頭較標準高爾夫球桿頭呈現出的應力分布更能擴及整個插鞘。此種應力分布顯示插鞘是以更大的面積承受應力，因而能夠分散應力並降低材料變形的可能性。 As mentioned above, the example golf club head with the lower hosel hole does not show any highly isolated areas of stress concentration. Although the maximum stress on both club heads is roughly the same, the example golf club head shows a stress distribution that is more spread out across the hosel than the standard golf club head. This stress distribution shows that the hosel is bearing stress over a larger area, which can spread the stress and reduce the possibility of material deformation.
與標準桿頭相較之下，範例桿頭插鞘孔較低且插鞘較短。球桿的所有其他組件則維持相同。範例桿頭在插鞘展現分散的應力，而標準桿頭則在插鞘下方部分出現一條集中應力。由此可知，短型插鞘及低位插鞘孔可減少插鞘下方部分的應力集中，使得應力更能夠分散於整個插鞘。這表示相比於不具有短型插鞘及低位插鞘孔的標準桿頭，範例桿頭在彎折時較不易產生嚴重材料變形。 Compared to the standard club head, the example club head has a lower hosel hole and a shorter hosel. All other components of the club remain the same. The example club head shows distributed stress in the hosel, while the standard club head shows a concentrated stress in the lower part of the hosel. It can be seen that the short hosel and low hosel hole can reduce the stress concentration in the lower part of the hosel, so that the stress can be more distributed throughout the hosel. This means that compared to the standard club head without a short hosel and low hosel hole, the example club head is less likely to produce severe material deformation when bent.
範例IV-本發明桿頭兩種實施例與對照桿頭的應力分散比較 Example IV-Comparison of stress distribution between two embodiments of the club head of the present invention and a control club head
範例IV藉由質性比較驗證低位或加深插鞘孔對於應力集中的影響。具體而言，範例IV基於表面積比較應力分散情況，比較項目包括 具有低位插鞘孔且未設置外部槽口的兩種本發明桿頭實施例以及一種採用普通插鞘孔構形且同樣未設外部槽口的傳統鐵桿型高爾夫球桿頭實施例。 Example IV verifies the effect of a low or deep hosel hole on stress concentration by qualitative comparison. Specifically, Example IV compares stress dispersion based on surface area, and the comparison items include two embodiments of the club head of the present invention with a low hosel hole and no external notch, and a conventional iron-type golf club head embodiment with a normal hosel hole configuration and no external notch.
範例桿頭1具有較對照桿頭更深入桿頭的插鞘孔。範例桿頭1的插鞘孔終止於與擊球面上最近踵部邊緣對齊的平面。範例桿頭2具有較對照桿頭及範例桿頭1更深入桿頭的插鞘孔。範例桿頭2的插鞘孔持續深入桿頭，因此掏空整個桿頭內部，使本體空腔與插鞘孔共同形成單一連續的空間。對照桿頭、範例桿頭1及範例桿頭2的插鞘孔壁具有彼此相同且不變的厚度。
參照圖13至圖15，對照桿頭在單位表面積上承受的應力高於範例桿頭1及範例桿頭2兩者。增大插鞘孔表面積即是增加彎折可發生的區域大小。因此，當以外力彎折插鞘時，插鞘會在可允許利用的整個表面積上發生彎折。如此一來，插鞘孔深度增加即代表應力的分散區域增加，也意味應力集中減少，從而降低結構失效或顯著應力斑痕出現的風險。
Referring to Figures 13 to 15, the stress per unit surface area of the comparison club head is higher than that of both

上述九種範例桿頭皆具有相同的本體結構及尺寸，包括體積 及插鞘孔深度與構形，不同之處僅在於材料及下方區域插鞘壁厚。各種材料的密度差異在質量上造成對應差異。插鞘壁厚差異在質量上增加的差別則並不大。 The nine examples above all have the same body structure and dimensions, including volume and hosel hole depth and configuration, and the only differences are in the material and hosel wall thickness in the lower area. The density differences of various materials cause corresponding differences in quality. The difference in hosel wall thickness does not increase the difference in quality.
結果顯示硬度增加使得插鞘彎折期間承受的應力大小減少，並且插鞘壁厚增加也使得插鞘彎折期間承受的應力大小減少。一般而言，當力量維持不變時，材料硬度增加會導致應力更加集中，但承受的最大應力程度降低且彎折量減少。 The results show that increased stiffness reduces the amount of stress the hosel experiences during bending, and increased hosel wall thickness also reduces the amount of stress the hosel experiences during bending. Generally speaking, when the force remains constant, an increase in material stiffness results in more concentrated stress, but a lower maximum stress level and less bending.
數據並顯示，若輸入力量不變，則要對應不同材料達成同量插鞘彎折，就必須改變插鞘壁厚。換言之，為維持彎折插鞘所需的力量輸入，隨著材料硬度及降伏強度增加，插鞘壁厚必須減少。如此一來，組裝人員在製造後調整桿頭高擊斜面及桿底能夠獲得一致的力量期待及一致的手感，因而改善組裝程序。 The data also shows that if the input force remains constant, the wall thickness of the hosel must be changed to achieve the same amount of hosel flex for different materials. In other words, to maintain the force input required to flex the hosel, as the material hardness and yield strength increase, the hosel wall thickness must be reduced. This allows assemblers to achieve consistent force expectations and consistent feel when adjusting the clubhead loft and sole after manufacturing, thereby improving the assembly process.
