Abstract

The aim of the invention is to achieve an extremely accurate golf stroke, in particular a golf stroke that is characterised by a narrow dispersion and a rounder swing. To achieve this, the golf-club head has one or more weight inserts in the sole of the club. Said weight inserts are located in an area of the sole that lies in or as near as possible to an imaginary/theoretical extension of the golf-club shaft, and/or the golf-club head has an aerodynamic shape, which generates an additional centrifugal force and/or an additional driving force during the swing of the club.

Description

GolfschlägerkopfGolf club head
Die vorliegende Erfindung betrifft einen Golfschlägerkopf ( Holz oder Eisen), der mit einem Golfschlägerschaft verbunden bzw. verbindbar ist.The present invention relates to a golf club head (wood or iron) which is connected or connectable to a golf club shaft.
Aufgabe der Erfindung ist es, einen Golfschiägerkopf zur Verfügung zu stellen, bei dem beim Schlägerschwung zusätzliche Kräfte erzeugt werden, die einen besonders genauen Golfschlag ermöglichen, insbesondere einen Golfschlag, der durch eine geringere Streuung und einen runderen Schwung gekennzeichnet ist.The object of the invention is to provide a golf club head, in which additional forces are generated during the club swing, which enable a particularly precise golf shot, in particular a golf shot which is characterized by less scatter and a rounder swing.
Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlagen, daß der Golfschiägerkopf in der Schlägersohle ein oder mehrere Gewichtseinlagen aufweist, wobei die Gewichtseinlagen nur in einem Bereich der Schlägersohle angeordnet sind, der in bzw. möglichst nahe einer gedachten/theoretischen Verlängerung des Golfschlägerschaftes liegt und/oder der Golfschiägerkopf eine aerodynamische Form aufweist, so daß beim Schlägerschwung eine zusätzliche Zentrifugalkraft und/oder eine zusätzliche Abtriebskraft erzeugt wird.To achieve this object, it is proposed according to the invention that the golf club head has one or more weight inserts in the club sole, the weight inserts being arranged only in an area of the club sole which is in or as close as possible to an imaginary / theoretical extension of the golf club shaft and / or the golf club head has an aerodynamic shape so that an additional centrifugal force and / or an additional downforce is generated during the swing of the club.
Durch die Gewichtseinlagen, die vorzugsweise aus Materialien mit extrem hohen Gewicht, wie beispielsweise Wolfram, Wolframkupfer, Titan oder dergi. ausgebildet sind, wird ein niedrigerer Schwerpunkt erreicht, so daß der Schiägerschwung leicht durch den Goifbail gleitet. Durch die Plazierung der Gewichtseinlagen in der Schlägersohle möglichst nahe der Verlängerung des Schaftes wird eine Verlängerung des Schwung-Hebelarmes zum tiefstmöglichen Punkt erreicht und damit eine zusätzliche Zentrifugalkraft ohne die Torsion des Schaftes zu vergrößern, sodaß ein besonders streuungsarmer Goifschiag erreicht wird.Due to the weight inserts, which are preferably made of materials with extremely high weight, such as tungsten, tungsten copper, titanium or dergi. trained, a lower center of gravity is reached, so that the Schiäger swing easily slides through the Goifbail. By placing the weight inserts in the club sole as close as possible to the extension of the shaft, the swing lever arm is extended to the lowest possible point and thus an additional centrifugal force without increasing the torsion of the shaft, so that a particularly low-scatter Goifschiag is achieved.
Jede weitere Gewichtsverlagerung bei Holz- oder Eisengoifschlägerköpfen zur Schlägerkopfspitze hin würde einen zusätzlichen, unerwünschten Hebelarm bewirken, welcher die Torsion des Schaftes verstärken und der möglichst "squaren" (im rechten Winkel zur Flugbahn) Blattstellung im Treffmoment entgegen wirken würde. Gewichtseinlagen, die nicht in der Schlägersohle, sondern an einem höheren Punkt eingelegt werden, führen nicht zu der erfindungsgemäßen maximal möglichen Schwerpunktsverlegung und damit auch nicht zur optimalen Ausnutzung der maximalen Zentrifugalkraft.Any further weight shift in the case of wooden or iron goat club heads towards the club head tip would bring about an additional, undesirable lever arm, which would increase the torsion of the shaft and would counteract the "squaren" (at right angles to the trajectory) blade position at the moment of impact. Weight deposits that are not in the club sole, but at a higher one Point inserted, do not lead to the maximum possible center of gravity according to the invention and thus not to the optimal use of the maximum centrifugal force.
Durch die gemäß der Erfindung vorgeschlagene aerodynamische Form des Golfschlägerkopfes wird beim Schiägerschwung eine zusätzliche Abtriebskraft erzeugt, durch die ein runder Schwung und ein tieferes „Durchschlagen" des Golfballes erreicht wird. Bevorzugt ist zur Erzeugung der Abtriebskraft der Schlägerkopf tragflügelförmig ausgebildet und dabei der Schlägerkopfboden nach unten gewölbt und die Schiägerkopfoberseite teilweise oder gesamt nach unten/innen gewölbt. Die Innenwölbung kann unterschiedlich stark ausgeprägt sein. Sie kann näher an der Schlagfläche beginnen und flach auslaufen oder etwas weiter hinten beginnen und steiler nach unten führen. Jegliche Ari der Wölbung, welche Abtrieb hervorruft, kann zur Ausführung kommen. Für schnelle Schwinger wäre ein flaches Abtriebsprofil geeigneter, während für langsame Schwinger ein gewölbteres Profil passend sein kann. Zur Orientierung können die ein- bzw. ausgefahrenen Landeklappen eines Flugzeugflügels dienen. Des weiteren kann an der Kopfaußenseite zusätzlich eine Aufkantung eingearbeitet oder angefügt sein, welche einen Luftdruckausgleich zwischen Ober- und Unterteil reduziert.Due to the aerodynamic shape of the golf club head proposed according to the invention, an additional downforce is generated during the swing of the club, by means of which a round swing and a deeper "punching through" of the golf ball is achieved. The club head is preferably wing-shaped to generate the downforce and the bottom of the club head is down curved and the top of the ski head partially or completely curved downwards / inwards. The internal curvature can be differently pronounced. It can start closer to the face and end flat or start a little further back and lead downwards. Any ari of the curvature that causes downforce A flat output profile would be more suitable for fast transducers, while a more curved profile could be suitable for slow transducers. The retracted or extended flaps of an airplane wing can be used for orientation. Furthermore, an upturn can be incorporated or added to the outside of the head, which reduces air pressure compensation between the upper and lower part.
Auf der Oberseite können, wie auf Flugzeugtragflächen häufig zu sehen, kleine Stabilisierungsprofile, beispielsweise Flettnerprofile, eingearbeitet oder aufgesetzt werden, welche die Luftströmung begünstigen und die Vibration reduzieren.As can often be seen on aircraft wings, small stabilization profiles, for example Flettner profiles, can be incorporated or placed on the upper side, which favor the air flow and reduce the vibration.
Der Vorteil dieses abtriebsorientierten Schlägerkopfprofiis liegt in der zusätzlichen Ausnutzung des Abtriebs um hierdurch einen runden Schwung und ein tieferes „Durchschlagen „ des Balles zu erreichen,. Die allgemein gewünschte Streckung der Arme wird durch die zusätzliche Zugkraft gefördert.The advantage of this downforce-oriented club head professional lies in the additional use of the downforce in order to achieve a round swing and a deeper "striking" of the ball. The generally desired extension of the arms is promoted by the additional pulling force.

In den Fig. 1 und 2 weist der Eisengolfschlägerkopf 10 Gewichtseinlagen 1 auf, die im bzw. möglichst nahe dem Bereich 12 der Schlägersohle 13 angeordnet sind, der in einer gedachten/theoretischen Verlängerung 14 des Golfschlägerschaftes 15 liegt.
