Description
本發明之特徵係大致有關於高爾夫球桿及高爾夫球桿頭,且特別有關於一具空氣動力特性之高爾夫球桿及高爾夫球桿頭。
當一高爾夫球被一高爾夫球桿打擊時移動之距離大部份是由在與該高爾夫球之撞擊點處的球桿頭速度來決定,球桿頭速度則會受由球桿頭所產生風阻或曳力影響,特別是在具有一1號木桿之大球桿頭尺寸時尤然。一1號木桿、球道木桿或金屬木桿之球桿頭在其揮桿路徑上特別地產生明顯示之空氣動力曳力。由該球桿頭產生之曳力導致球桿頭速度降低,因此在高爾夫球被打擊後之移動距離減少。
不僅在撞擊點處,同時亦在向上揮桿直到與該高爾夫球撞擊之點時減少該球桿頭之曳力將產生較佳之球桿頭速度及較大之高爾夫球移動距離。提供一減少或克服某些或所有本來存在先前習知裝置中之困難的高爾夫球桿頭是必要的,依據以下本發明之揭露及某些實施例之詳細說明,發明所屬技術領域中具有通常知識者可了解特別之優點。
本發明之原理可用來提供一具有較佳空氣動力效能之高爾夫球桿頭。依據第一方面,一種高爾夫球桿頭包括一本體構件,該本體構件具有一擊球面、一趾部、一跟部、一底部、及一裙部,該裙部延伸在該冠部與該底部之間且在該趾部與該跟部之間。一在該本體構件上之曳力減少結構構形成在一由一向後揮桿之終點經過一向下揮桿之高爾夫揮桿時,減少該本體構件之曳力。
依據另一方面,一高爾夫球桿頭包括一本體構件,該本體構件具有一擊球面、一趾部、一跟部、一底部、及一裙部,該裙部延伸在該冠部與該底部之間且在該趾部與該跟部之間。一實質V形凹部形成在該底部中且具有一頂點及一對腿部,該頂點位在接近該擊球面及該跟部且遠離該裙部及該趾部處,該對腿部延伸至一接近該趾部且遠離該擊球面之點,並朝該裙部彎曲且遠離該擊球面。
依據又一方面,一高爾夫球桿總成包括一桿部及一固定於該桿部之一第一端的球桿頭。該球桿頭包括一本體構件,該本體構件具有一擊球面、一趾部、一跟部、一底部、及一裙部,該裙部延伸在該冠部與該底部之間且在該趾部與該跟部之間。一連續溝槽由該趾部之一前部延伸至一後緣且沿著該裙部之全長延伸。
藉依據某些實施例提供一高爾夫球桿頭具有一由該趾部之一前部延伸至一後緣且沿著該裙部之全長延伸的連續溝槽,可減少該高爾夫球桿頭在其向前向上揮桿直到與該高爾夫球撞擊之點時之曳力。這是極為有利的,因為較小之曳力將產生較大之球桿頭速度且因此在該高爾夫球被該球桿頭打擊後產生較大之移動距離。
在此揭露之這些與其他特徵及優點將可由以下某些實施例之詳細說明進一步了解。

以上圖式並不一定依比例繪製,應了解的是提供本發明之特殊實施例之圖像,且本質上僅是觀念性的且顯示所涉及之原理。在圖中顯示之高爾夫球桿頭的某些特徵已相對其他者放大與扭曲以便說明與了解。在各種可選擇實施例中顯示之類似或相同組件與特徵在圖式中使用相同之符號,在此所揭露之高爾夫球桿頭將具有由所欲應用與它們所使用之環境部份地決定的構形與組件。
一高爾夫球桿10之說明性實施例顯示於第1圖中且包括一桿部12及一連接於該桿部12之高爾夫球桿頭14,高爾夫球桿頭14可以是任何1號木桿、木桿等。高爾夫球桿10之桿部12可由如鋼、鋁、鈦、石墨、或複合材料,以及合金及/或其組合等包括在先前技術中已知及使用之各種材料製成。此外,該桿部12可以任何所需方式,包括以在先前技術中已知及使用之習知方式(例如,在一桿頸元件處透過黏著劑或接合劑,透過熔接技術(例如,焊接、硬焊、軟焊等),透過螺紋或其他機械式連接器,透過摩擦配件,透過扣持元件結構等)連接至該球桿頭14上。一抓握或其他握把元件16定位在桿部12上以提供一高爾夫球員一用以抓住高爾夫球桿桿部之防滑表面。抓握元件16可以任何所需方式,包括以在先前技術中已知及使用之習知方式(例如,透過黏著劑或接合劑,透過螺紋或其他機械式連接器,透過熔接技術,透過摩擦配件,透過扣持元件結構等)連接於桿部12。
球桿頭14包括本體構件15及一桿頸16,桿部12以習知方式連接於桿頸16。本體構件15包括多數部份或表面,如圖所示,這例子之本體構件15包括一擊球面17、一冠部18、一趾部20、一裙部22、一跟部24、及一底部26。裙部22位於與擊球面17相反側,且延伸在冠部18與底部26之間,並且在趾部20與跟部24之間。
一曳力減少結構27設置在本體構件15上以減少一使用者由使用者向後揮桿之終點經過向下揮桿之高爾夫揮桿時在球桿頭14上之曳力。曳力減少結構27在一使用者之高爾夫揮桿之整個向下揮桿時提供較小之曳力,而不是僅在撞擊點處提供。
在與一高爾夫球之撞擊點處,擊球面17實質上垂直於該球桿頭14之移動方向及該高爾夫球之飛行路徑。當使用者向後揮桿時及當使用者向下揮桿時,使用者之手扭轉高爾夫球桿10,以產生一偏移(yaw),藉此樞轉擊球面17遠離其衝擊處之位置。當擊球面17在撞擊點處之方位被視為0°,在該向後揮桿時,擊球面17扭轉遠離使用者朝向趾部20與裙部22至一最大90°之偏移,在此處,跟部24是球桿頭24之前緣。
在某些實施例中,曳力減少結構27包括一環繞形成在球桿頭14之一周邊之一部份的連續溝槽28。如第2-4圖所示,溝槽28由趾部20之一前部30完全延伸至趾部20之一後緣32,且接續至裙部22上。溝槽28接著延伸通過裙部22之全長,如第4圖所示,溝槽28逐漸縮小至在跟部24之一後部34中的一端。在某些實施例中,在趾部20之前部30處之溝槽28可沿著底部26之一部份轉彎且連續。
在所示實施例中,溝槽28實質呈U形。在某些實施例中,溝槽28具有一大約15mm之最大深度。但是,應了解的是該溝槽28可沿其長度具有任何深度。
當空氣流過球桿頭14之本體構件15之冠部18及底部26時,它會分離,這會造成曳力增加。溝槽28係用以減少空氣分離之傾向,藉此減少曳力且改善球桿頭14之空氣動力特性,這將增加球桿頭速度及球在被打擊後將移動之距離。使溝槽28沿著趾部20延伸是特別有利的,因為對大部份球桿頭14之揮桿路徑而言,如上所述,球桿頭14之前導部份是跟部24且球桿頭14之尾緣是趾部20。如此,在大部份之揮桿路徑時可得到由溝槽28所提供之空氣動力的好處。溝槽28沿著裙部22延伸之部份在球桿頭14與該球之撞擊點處提供空氣動力的好處。
在第1-6圖所示之實施例中,本體構件15是一習知之方形頭,雖然以幾何觀點來看不是一真正方形,但是方形頭本體構件15之冠部18及底部26相較於一傳統圓頭球桿實質上是方形的。
在揮桿時由溝槽28所提供之曳力減少的一例子顯示在下表中,在該表中,顯示一方形頭設計及一具有溝槽28之曳力減少結構之方形頭設計兩者,在整個高爾夫揮桿期間不同偏移角的曳力值。
可看到的是在撞擊點處,即該偏移角為0°處,具有溝槽38之方形球桿頭之曳力是該方形球桿頭之曳力的大約48.2(4.01/8.32)。但是,在整個揮桿期間該方形球桿頭之總曳力的和為一544.39之總曳力,而具有溝槽38之方形球桿頭之總曳力則是216.75。如此,具有溝槽38之方形球桿頭之總曳力是該方形球桿頭之總曳力的大約39.8(216.75/544.39)。因此,加總整個揮桿期間之曳力會產生與僅計算在撞擊點處之曳力非常不同的結果。
在某些實施例中,如第5-6圖所示,一凹部36形成在底部26中。在所示實施例中,凹部36實質呈V形且其形狀之一頂點38係位在接近擊球面17及跟部24處。即,頂點38位在靠近擊球面17及跟部24且遠離裙部22及趾部20處。凹部36包括一對腿部40,該對腿部40延伸至一接近趾部20且遠離擊球面17之點,並且朝裙部22彎曲且遠離擊球面17。
多數第二凹部42形成在凹部36之一底面43中,在所示實施例中,各第二凹部42是一正梯形,且其較小底44較靠近跟部表面24且其較大底46較靠近趾部表面20,並且斜邊45連接較小底44與較大底46。在所示實施例中,各第二凹部42之深度由其在較小底44處之最大量變化至與凹部36之底面43齊平之較大底46。
另一實施例之一球桿頭54顯示在第7-10圖中,球桿頭54具有一更傳統之圓頭形狀。在此應了解的是該用語“圓頭”不是指一完全圓之頭,而是具有一大致或實質圓形輪廓者。
連續溝槽28環繞形成在球桿頭54之一周邊之一部份,如第7-10圖所示,溝槽28由趾部20之一前部30完全延伸至趾部20之一後緣32,且接續至裙部22上。溝槽28接著延伸通過裙部22之全長,如第4圖所示,溝槽28逐漸縮小至在跟部24之一後部34中的一端。
如此,雖然已顯示、說明及指出各種實施例之基本新穎特徵,但是應了解的是在不偏離本發明之精神與範疇的情形下,發明所屬技術領域中具有通常知識者可對所示裝置之形態與細部結構及其操作進行各種省略、替換及改變。例如,在此要清楚表示的是以實質相同之方式實質上執行相同功能以達成相同結果之這些元件及/或步驟的所有組合係在本發明之範圍內。由一所述實施例至另一實施例之元件的替換也是完全可預期與實現的,因此,僅受限於由以下申請專利範圍之範疇所述者。
