Description

Die Erfindung betrifft einen Golfschlägerkopf, insbesondere einen Golfputterkopf, mit einem Schlagteil mit einer Schlagfläche und mit zwei gegenüber der Schlagfläche von den seitlichen Endabschnitten des Schlagteils ausgehenden und einander berührungslos kreuzenden Bügeln. Die Erfindung betrifft ferner einen Golfschläger mit einem derartigen Golfschlägerkopf sowie ein Verfahren zur Herstellung eines Golfschlägerkopfes, insbesondere eines Golfputterkopfes, mit einem Schlagteil mit einer Schlagfläche und mit zwei gegenüber der Schlagfläche von den seitlichen Endabschnitten des Schlagteils ausgehenden und einander berührungslos kreuzenden Bügeln.The invention relates to a golf club head, in particular a golf putter head, with a striking part with a striking face and with two stirrups extending from the lateral end sections of the striking part opposite the striking face and crossing each other without contact. The invention also relates to a golf club with a golf club head of this type and a method for producing a golf club head, in particular a golf putter head, with a striking part with a striking surface and with two stirrups extending from the side end sections of the striking part opposite the striking face and crossing each other without contact.

Sogenannte Putter werden beim Golfsport dafür benützt, den Golfball auf dem Grün einzulochen bzw. zu putten. Der Golfputter ist ein Golfschläger mit einem auf das Putten abgestimmte Eigenschaften aufweisenden Golfputterkopf und einem Schaft mit einem Griff, wobei der Schaft mit dem Golfputterkopf fest verbunden ist. Zum Einstellen der Facebalance, von Heel Weighting oder Toe Weighting werden am Golfputterkopf auswechselbare Gewichte positioniert, die auch eine Erhöhung des Gesamtgewichtes des Putterkopf von bis zu 250 g ermöglichen.So-called putters are used in golf to hole or putt the golf ball on the green. The golf putter is a golf club with a golf putter head which has properties matched to putting and a shaft with a handle, the shaft being firmly connected to the golf putter head. To adjust the face balance, heel weighting or toe weighting, exchangeable weights are positioned on the golf putter head, which also allow the total weight of the putter head to be increased by up to 250 g.

Ein Golfschlägerkopf der eingangs genannten Art ist aus der EP 1 892 019 B1 bekannt. Die bei diesem Golfschlägerkopf vorgesehenen, einander berührungslos kreuzenden Bügel sind an den Endabschnitten des Schlagteils angeschraubt. Es hat sich nun herausgestellt, dass sich diese Verbindungsstellen nach einer gewissen Benützungsdauer des Golfschlägers etwas lockern, was zu einem unerwünschten Schlagverhalten des Golfputters führt. Dadurch wird der besondere Vorteil der gekreuzt und berührungslos angeordneten Bügel, nämlich die Unempfindlichkeit des Golfputterkopfes gegen ein Verdrehen, wenn seine Schlagfläche seitlich des Zentrums getroffen wird, beeinträchtigt.A golf club head of the type mentioned is from EP 1 892 019 B1 known. The brackets that cross each other in a contactless manner and are provided in this golf club head are screwed onto the end sections of the striking part. It has now been found that these connection points loosen somewhat after a certain period of use of the golf club, which leads to an undesirable hitting behavior of the golf putter. This has the special advantage of the crossed and contactless arranged brackets, namely the insensitivity of the golf putter head to twisting when its face is hit to the side of the center, impaired.

Der Erfindung liegt die Aufgabe zugrunde, einen Golfschlägerkopf der eingangs genannten Art auf qualitativ hochwertige Weise derart auszuführen und herzustellen, dass der Golfschlägerkopf auch bei intensiver Benützung dauerhaft stabil bleibt.The invention is based on the object of designing and producing a golf club head of the type mentioned at the beginning in a high-quality manner in such a way that the golf club head remains permanently stable even with intensive use.

Gelöst wird die gestellte Aufgabe erfindungsgemäß dadurch, dass der Schlagteil gemeinsam den Bügeln ein Monoteil aus einer hochfesten Aluminiumlegierung ist.The object is achieved according to the invention in that the striking part, together with the stirrups, is a mono part made of a high-strength aluminum alloy.

Was das Verfahren zur Herstellung betrifft, wird die gestellte Aufgabe erfindungsgemäß dadurch gelöst, dass der Schlagteil gemeinsam mit den Bügeln aus einem Stück einer hochfesten Aluminiumlegierung gefräst wird.As far as the method of production is concerned, the object is achieved according to the invention in that the striking part is milled together with the stirrups from a piece of a high-strength aluminum alloy.

Durch die Ausführung und Herstellung als Monoteil bleibt der Golfschlägerkopf dauerhaft stabil, auch bei intensiver Benützung erfolgt keine Änderung seiner Schlageigenschaften. Darüber hinaus ist gewährleistet das Material - eine hochfeste Aluminiumlegierung - einen qualitativ hochwertigen Golfschlägerkopf.Due to the design and manufacture as a mono-part, the golf club head remains permanently stable, even with intensive use there is no change in its impact properties. In addition, the material - a high-strength aluminum alloy - guarantees a high quality golf club head.

Bei einer bevorzugten Ausführung ist die Aluminiumlegierung eine Aluminiumlegierung des Legierungstyps AlZnMgCu, insbesondere eine Legierung des Typs EN AW 7075, bevorzugt sogenanntes Flugzeugaluminium (AlZnMgCul,5). Flugzeugaluminium ist wegen seiner hohen Zugfestigkeit besonders gut geeignet. Das Material des Monoteils des Golfschlägerkopfes kann jedoch auch eine andere bezüglich der Zugfestigkeit entsprechende Aluminiumlegierung sein.In a preferred embodiment, the aluminum alloy is an aluminum alloy of the alloy type AlZnMgCu, in particular an alloy of the type EN AW 7075, preferably so-called aircraft aluminum (AlZnMgCul, 5). Aircraft aluminum is particularly suitable because of its high tensile strength. The material of the mono-part of the golf club head can, however, also be another aluminum alloy which corresponds to the tensile strength.

Das Monoteil ist weiters bevorzugt durch Fräsen hergestellt. Fräsen lässt sich mit entsprechenden Fräsmaschinen vollautomatisch durchführen.Furthermore, the mono-part is preferably produced by milling. Milling can be carried out fully automatically with the appropriate milling machines.

Bei einer besonders ausgewogenen Ausführung des Golfschlägerkopfes sind die Bügel im Kreuzungsbereich mit je einer Vertiefung versehen, wobei sich die Bügel im Bereich der Vertiefungen berührungslos überlappen.In a particularly balanced design of the golf club head, the stirrups are each provided with a recess in the intersection area, the stirrups overlapping in the area of the indentations without contact.

Beim Schlagen mit dem Golfschlägerkopf ertönt ein heller Klang. Dieser kann bei Bedarf dadurch gedämpft werden, dass im Kreuzungsbereich zwischen den Bügeln ein Klangdämpfungselement angeordnet wird. Dieses Klangdämpfungselement wird bevorzugt an einem der Bügel befestigt, berührt den anderen Bügel und besteht vorzugsweise aus Silikon.When striking with the golf club head, a bright sound is heard. If necessary, this can be dampened by arranging a sound dampening element in the crossing area between the brackets. This sound-damping element is preferably attached to one of the brackets, touches the other bracket and is preferably made of silicone.

Die Erfindung betrifft ferner einen Golfschläger mit einem Golfschlägerkopf, welcher gemäß einem oder mehreren der Ansprüche 1 bis 8 ausgestaltet ist.The invention further relates to a golf club with a golf club head, which is designed according to one or more of claims 1 to 8.

Weitere Merkmale, Vorteile und Einzelheiten der Erfindung werden nun anhand der Zeichnung, die schematisch ein Ausführungsbeispiel darstellt, näher beschrieben. Dabei zeigen

  • Fig. 1 und Fig. 2 Ansichten der beiden Seiten des Golfschlägerkopfes und
  • Fig. 3 eine Schrägansicht des Golfschlägerkopfes.
Further features, advantages and details of the invention will now be described in more detail with reference to the drawing, which schematically shows an embodiment. Show
  • FIGS. 1 and 2 Views of the two sides of the golf club head and
  • Fig. 3 an oblique view of the golf club head.

Die Figuren zeigen einen Golfschlägerkopf 1, welcher insbesondere als Putterkopf geeignet ist und Verwendung findet und einen länglichen, stabförmigen Schlagteil 2 mit einer Schlagfläche 2a an der stirnseitigen Außenfläche aufweist. Von jedem Endabschnitt des Schlagteils 2 ragt gegenüber der Schlagfläche 2a ein bei der gezeigten Ausführung in Draufsicht bogenförmig verlaufender Bügel 3 ab. Die beiden übereinstimmend oder weitgehend übereinstimmend ausgeführten Bügel 3 verlaufen vom Schlagteil 2 unter kleiner werdenden spitzen Winkeln zu diesem aufeinander zu und kreuzen dabei einander in ihren mittleren Bereichen. Mit einem freien Endabschnitt 3a überragt jeder Bügel 3 den Kreuzungsbereich und endet auf der Höhe des Ansatzbereiches des jeweils anderen Bügels 3 am Schlagteil 2. Jeder Bügel 3 weist im Kreuzungsbereich eine von ihrer Gestalt an die Außenkonturen des kreuzenden Bügels 3 angepasste Vertiefung 4 auf, sodass die beiden Bügel 3 im Bereich der Vertiefungen 4 einander überlappen jedoch nicht berühren. Die Vertiefungen 4 sind derart dimensioniert, dass zum jeweils zweiten Bügel 3 seitlich Spalten in der Größenordnung von insbesondere 1,0 mm bis 2,0 mm, am Boden der Vertiefungen 4 von 2,0 mm bis 3,0 mm verbleiben.The figures show a golf club head 1, which is particularly suitable and used as a putter head and has an elongated, rod-shaped striking part 2 with a striking surface 2a on the front outer surface. From each end section of the striking part 2 protrudes from the striking face 2a, in the embodiment shown, a bow 3 extending in a top view. The two coincident or largely coincident brackets 3 run from the striking part 2 at decreasing acute angles to this and cross one another in their central areas. With a free end section 3a, each bracket 3 protrudes beyond the crossing area and ends at the level of the attachment area of the other bracket 3 on the striking part 2. Each bracket 3 has a recess 4 in the crossing area that is adapted to the shape of the outer contours of the crossing bracket 3, so that the two brackets 3 in the region of the depressions 4 overlap but do not touch. The depressions 4 are dimensioned in such a way that gaps laterally with respect to the second bracket 3 in each case in the order of magnitude of in particular 1.0 mm to 2.0 mm, and 2.0 mm to 3.0 mm at the bottom of the depressions 4.

Die Endabschnitte 3a der Bügel 3 sind bei der gezeigten Ausführung in Draufsicht im Wesentlichen runde, insbesondere kreisförmige Verbreiterungen der Bügel 3 und an jeder Bügelseite jeweils mit einer mit einem Innengewinde versehenen Vertiefung zum Einschrauben von Gewichten 5 versehen. Auf diese Weise können unterschiedlich schwere Gewichte 5 auf austauschbare Weise an den Bügelendbereichen positioniert werden.In the embodiment shown, the end sections 3a of the brackets 3 are essentially round, in particular circular, widenings of the brackets 3 and each side of the bracket is provided with an internally threaded recess for screwing in weights 5. In this way, weights 5 of different weights can be positioned on the temple end areas in an exchangeable manner.

Die an die Schlagfläche 2a unmittelbar anschließenden Seitenflächen 2b des Schlagteils 2 gehen vorzugsweise kontinuierlich in Bügelseitenflächen über. Im Bereich der seitlichen Endabschnitte einer dieser Seitenflächen 2b des Schlagteils 2 ist jeweils eine weitere, in Draufsicht kreisförmige Vertiefung mit Innengewinde ausgebildet, sodass auch an diesen Positionen Gewichte 5 austauschbar angeschraubt werden können. An der gegenüberliegenden Seitenfläche 2b des Schlagteils 2 ist eine Buchse 6 zur Aufnahme und Befestigung eines nicht dargestellten Schlägerschaftes ausgebildet.The side surfaces 2b of the striking part 2 directly adjoining the striking surface 2a preferably merge continuously into the side surfaces of the bow. In the area of the lateral end sections of one of these side surfaces 2b of the striking part 2, a further recess with an internal thread, which is circular in plan view, is formed so that weights 5 can also be screwed on interchangeably at these positions. On the opposite side surface 2b of the striking part 2, a socket 6 for receiving and fastening a club shaft, not shown, is formed.

Bei einer bevorzugten Ausführung ist an einem der Bügel 3 im Kreuzungsbereich eine diesen Bügel 3 durchsetzende Bohrung 7 ausgebildet, in welcher ein Klangdämpfungselement 8 eingesetzt werden kann, welches den zweiten Bügel 3 am Boden seiner Vertiefung 4 berührt bzw. kontaktiert. Das Klangdämpfungselement 8 ist beispielsweise ein Silikonstoppel und hat die Wirkung, den beim Schlag auf den Golfball verursachten Klang zu dämpfen. Das Klangdämpfungselement 8 beeinflusst in keiner Weise die erwünschte gegenseitige Beweglichkeit der einander nicht unmittelbar berührenden Bügel 3 und gleitet bei geringfügigen Relativbewegungen der beiden Bügel 3 an dem von ihm kontaktierten Bügel 3 ohne nennenswerte Reibung ab.In a preferred embodiment, a hole 7 penetrating this bracket 3 is formed on one of the brackets 3 in the intersection area, in which a sound-damping element 8 can be inserted which touches or contacts the second bracket 3 at the bottom of its recess 4. The sound dampening element 8 is, for example, a silicone stopper and has the effect of dampening the sound caused when hitting the golf ball. The sound-damping element 8 in no way affects the desired mutual mobility of the brackets 3, which do not directly contact one another, and slides off the bracket 3 contacted by it without significant friction when the two brackets 3 move slightly.

Der Golfschlägerkopf 1 ist - abgesehen von den an ihm positionierbaren Gewichten 5 und dem Klangdämpfungselement 8 - ein Monoteil, also einteilig ausgeführt und hergestellt. Das Monoteil besteht aus einer hochfesten Aluminiumlegierung, vorzugsweise aus einer Aluminiumlegierung des Legierungstyps AlZnMgCu, insbesondere aus EN AW 7075, bevorzugt sogenanntem Flugzeugaluminium (AlZnMgCu1,5) und wird aus einem Stück dieses Materials gefräst.The golf club head 1 is - apart from the weights 5 which can be positioned on it and the sound-damping element 8 - a mono-part, that is to say designed and manufactured in one piece. The mono part consists of a high-strength aluminum alloy, preferably an aluminum alloy of the alloy type AlZnMgCu, in particular of EN AW 7075, preferably so-called aircraft aluminum (AlZnMgCu1,5) and is milled from a piece of this material.

Zur Herstellung des Monoteils kann eine der üblichen mittels CAD gesteuerten und für eine Metallbearbeitung geeigneten Fräsmaschinen, beispielsweise eine Dreifachfräse oder eine Fünffachfräse, verwendet werden.One of the customary CAD-controlled milling machines suitable for metalworking, for example a triple milling machine or a five-way milling machine, can be used to produce the mono-part.

Das fertig gefräste Monoteil wird insbesondere mit einer Antigrip-Beschichtung versehen.The finished milled mono part is provided with an anti-slip coating in particular.

Durch die Gewichte 5 lässt sich einerseits eine seitliche Balancierung des Golfschlägerkopfes 1 und andererseits eine Verlagerung des Schwerpunktes des Golfschlägerkopfes 1, insbesondere in Richtung der freien Endabschnitte 3a der Bügel 3 vornehmen.By means of the weights 5, on the one hand, a lateral balancing of the golf club head 1 and, on the other hand, a shift of the center of gravity of the golf club head 1, in particular in the direction of the free end sections 3a of the bracket 3, can be undertaken.

Die einander kreuzenden, berührungslos angeordneten Bügel bewirken vorteilhafterweise eine Unempfindlichkeit des Golfschlägerkopfes 1 gegen Verdrehen, wenn seine Schlagfläche seitlich des Sweetspots (des Zentrums) getroffen wird. Die Ausführung als Monoteil sorgt vorteilhafterweise dafür, dass der Golfschlägerkopf auch bei intensiver Benützung dauerhaft stabil bleibt.The brackets that cross each other and are arranged in a contactless manner advantageously make the golf club head 1 insensitive to rotation when its striking surface is hit on the side of the sweet spot (the center). The design as a mono-part advantageously ensures that the golf club head remains permanently stable even with intensive use.
