Problems solved by technology

The hosel element of the driver is complex because it needs to connect to all of these pieces, but machining or forming the hosel limits the overall geometry and complexity of the resulting club head.
These manufacturing limitations can lead to issues with material availability and strength.
In particular, the materials that permit machining or tooling usually are not strong enough to accommodate current adjustable hosel de

Embodiment Construction

[0018]The present invention provides an improvement to the existing art of golf club manufacturing because it employs a separately cast hosel in a golf club head instead of machined or formed hosels. This improvement allows for the use of strong construction materials to support the complex geometry required to combine the hosel with other parts of the golf club head. The invention also allows for high, and efficient, production throughput during golf club manufacturing.

[0019]A preferred embodiment of the present invention is illustrated in FIGS. 1A-2B. As shown in FIGS. 1A-1C, the preferred embodiment includes a cast hosel 10 having a hosel tube 14 having a hosel bore 15 sized to releasably receive a shaft, a face portion 11, a crown portion 13, and a sole portion 16. The hosel bore 15 may further include a flange, such as the one shown in U.S. Pat. Nos. 8,096,895 and 8,002,644. The hosel also includes one or more adjustability features 12 which can be used to allow adjustment or i...

Abstract

The present invention is directed to a multi-piece golf club head having a metal hosel with adjustability features that is cast separately from a face component, sole, and crown, and then is permanently affixed to those other parts after casting is complete. The face component, sole, and crown may be composed of any suitable materials, but preferably each of the face component, the sole, and the crown are stamped from a metal material and are welded to the hosel.

Description

CROSS REFERENCES TO RELATED APPLICATIONS[0001]The present application claims priority to U.S. Provisional Patent Application No. 61 / 589,157, filed on Jan. 20, 2012, the disclosure of which is incorporated by reference in its entirety herein.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not ApplicableBACKGROUND OF THE INVENTION[0003]1. Field of the Invention[0004]The present invention relates to a multi-piece golf club head having a separately cast metal hosel.[0005]2. Description of the Related Art[0006]Golf club manufacturers have traditionally used expensive tooling or machining to form hosels in metal, wood-type golf clubs in an effort to make their designs more affordable and producible on a mass scale. This is particularly true for manufacturing multi-piece drivers, which typically include separately formed crowns, soles, and face components. The hosel element of the driver is complex because it needs to connect to all of these pieces, but machining or fo...
