Abstract
The invention relates to a head for golf clubs comprising a striking neck (3) via which it is joined to the shaft of a golf club. Said head has a bottom (4) with a fishscale-like profiling. The fishscale-like profiling of the bottom (4) is formed by scales having edges that are convexly curved away from the striking surface (2) of the head (1).
Description
Die Erfindung betrifft einen Golfschläger-Kopf, bestehend aus Holz, Kunststoff, Metall oder aus einer Kombination von wenigstens zweien dieser Werkstoffe.
Golfschläger-Köpfe aus den oben erwähnten Materialien haben sich bewährt. Bei den grossformatigen Schlägerköpfen mit grossflächiger Unterseite wird momentan fast ausschliesslich Metall als Werkstoff benützt.
Für eine grosse Fluglänge des Balls benötigt man eine möglichst hohe Schlägerkopf-Geschwindigkeit im Moment des Ballkontakts. Weil der kleine Golfball mit seinem relativ hohen Gewicht meistens etwas im Gras eingebettet liegt, muss der Schlägerkopf so tief durchgeschwungen werden, dass entweder vor oder beim Ballkontakt der Boden gestreift wird. Besonders im hohen Gras bewirkt dieser Bodenkontakt eine starke Bremswirkung auf den Schlägerkopf und somit einen verkürzten Ballflug. Die grösste Bremswirkung entsteht bei nassem Gras, was sehr oft der Fall ist.
Die Erfindung liegt die Aufgabe zu Grunde, die Bremswirkung auf den durchschwingenden Schlägerkopf bei Bodenkontakt zu reduzieren, um somit eine grosse Ballflugdistanz zu erreichen.
Erfindungegemäss wird dies dadurch erreicht, dass die zum Boden hin gerichtete Unterseite des Schlägerkopfes mit einem dreidimensionalen, fischschuppenartigen Profil versehen ist, welches nicht nur die benetzte Fläche reduziert, sondern auch mittels Lufteinschlüssen und Abrisskanten an den Schuppenhinterseiten reibungserzeugende Vakuumbildung verhindert.
Für die minimalste Bremswirkung zwischen Schlägerkopf-Unterseite und Boden verwendet man vorzugsweise eine Schlägerkopf-Unterseiten-Beschichtung aus einem reibungsarmen Werkstoff, wie Polytetrafluorethylen (z.B. Teflon), Polyacetal (z.B. Delrin) oder Polyethylen. Derartige Werkstoffe lassen sich auf einfache Art durch Heissprägung oder Injektionsverfahren herstellen.
Im Folgenden wird anhand des beiliegenden Bildes ein Ausführungsbeispiel der Erfindung näher beschrieben. Fig. 1 zeigt einen typisch geformten Golfschläger-Kopf 1 des so genannten Typs "Wood", vorzugsweise aus Metall, wie beispielsweise Stahl oder Titan-Legierung mit der horizontal gerillten Schlagfläche 2, dem mit dem Golfschaft verbindbaren Schlägerhals 3 sowie die Schlägerkopf-Sohle 4, welche mit einem dreidimensionalen, fischschuppenartigen Profil versehen ist, welches vorzugsweise mit einer reibungsarmen Kunststoffbeschichtung versehen ist.
Im Gegensatz zu Fairway-Schlägerköpfen, Typ "Wood", mit an der Sohle in Schlagrichtung angebrachten Rippen, auch genannt "Rails", zwecks Reibungswiderstands-Reduktion erzeugt, das fischschuppenartige Profil gemäss Patentanspruch 1 auch keinen erhöhten Reib-Widerstand, wenn der Schlägerkopf mit seiner Schlagfläche nicht ganz rechtwinklig über den Boden durchgeschwungen wird.
The invention relates to a golf club head consisting of wood, plastic, metal or a combination of at least two of these materials.
Golf club heads made from the materials mentioned above have proven their worth. In the large-sized club heads with a large underside, almost exclusively metal is currently used as the material.
For a long flight length of the ball you need the highest possible club head speed at the moment of contact with the ball. Because the small golf ball with its relatively high weight is mostly embedded somewhat in the grass, the club head must be swung through so deep that the ground is grazed either before or when the ball comes into contact. Especially in high grass, this contact with the ground causes a strong braking effect on the club head and thus a shorter ball flight. The greatest braking effect occurs when the grass is wet, which is very often the case.
The invention is based on the object of reducing the braking action on the swinging club head when in contact with the ground, in order to achieve a large ball flight distance.
According to the invention, this is achieved in that the underside of the club head, which is directed towards the ground, is provided with a three-dimensional, fish-scale-like profile, which not only reduces the wetted area, but also prevents friction-generating vacuum formation by means of air pockets and tear-off edges on the rear of the scale.
For the minimum braking effect between the underside of the club head and the bottom, a club head underside coating made of a low-friction material, such as polytetrafluoroethylene (e.g. Teflon), polyacetal (e.g. Delrin) or polyethylene, is preferably used. Such materials can be produced in a simple manner by hot stamping or injection processes.
An exemplary embodiment of the invention is described in more detail below with the aid of the attached picture. 1 shows a typically shaped golf club head 1 of the so-called "Wood" type, preferably made of metal, such as steel or titanium alloy, with the horizontally grooved club face 2, the club neck 3 which can be connected to the golf shaft, and the club head sole 4 , which is provided with a three-dimensional, fish scale-like profile, which is preferably provided with a low-friction plastic coating.
In contrast to fairway club heads, type "Wood", with ribs attached to the sole in the direction of impact, also called "rails", for the purpose of reducing frictional resistance, the fish scale-like profile according to claim 1 also has no increased frictional resistance when the club head is used its face is not swung across the floor at a right angle.
