Abstract
A golf club head 10 includes a perimeter member 12, preferably made of high density material, and a face plate insert 14, preferably made of lower density material. In one embodiment, the face plate insert 14 is formed by applying a shell member 38 to a core member 36 so that the shell member 38 encases the core member. Preferably, the shell member 36 is made by electrodepositing a nanometal having a grain size between 10 and 50 nanometers onto the core member 36. In a different embodiment, core member 36 may be sandwiched between two layers or walls of the shell material 38. The core member 36 is preferably of aluminium, foam metal, or plastics. The rear wall of the shell member 38 may be thinner than the front wall, which has U-shaped grooves formed on it. The thickness of the shell member 38 must be at least 1% of the thickness of the core member 36.
Description
MULTIPLE MATERIAL GOLF CLUB HEAD
BACKGROUND OF THE INVENTION
[001) This invention relates generally to golf equipment and, in particular, to golf club heads.
[0021 Iron-type golf clubs are intended primarily for second and later shots rather than tee shots. Often they are used for hitting shots from bare ground or sand as well as from turf.
Accordingly, conventional iron-type golf clubs are designed so that the club head and, in particular, the sole of the club head are made of a durable material such as iron, stainless steel or like. It is generally desirable for an iron-type golf club head to have perimeter weighting to increase its moment of inertia to resist twisting. It is also desirable for an iron-type golf club head to have a low center of gravity to enhance the ability of the club head to launch the golf ball in an appropriate trajectory and for the club head to be forgiving on off- center hits.
Conventional iron-type golf clubs accomplish some of these goals through the use of cavity back club heads, tuning ports in the club heads and, more recently, lightweight forged or rolled titanium club head faces attached to heavier perimeter members.
Accordingly, in a first aspect, the present invention provides a golf club head.

[005J Fig. 3 is a cross-sectional view of the club head of Fig. 1 taken along line 3-3; (0061 Fig. 4 is a cross-sectional view, similar to Fig. 2, of another embodiment of the face plate insert; and j007) Fig. 5 is a cross-sectional view, similar to Fig. 3, of a club head including the face plate insert of Fig. 4.
DESCRIPTION OF EMBODIMENTS OF THE INVENTION
1008] The drawing figures are intended to illustrate the general manner of construction and are not necessarily to scale. In the detailed description and in the drawing figures, specific illustrative examples are shown and herein described in detail. It is understood, however, that the drawing figures and the detailed description are not intended to limit the invention to the particular form disclosed, but are merely illustrative and intended to teach one of ordinary skill how to make and/or use the invention claimed herein and for setting forth the best mode for carrying out the invention.
(009J With reference to Figs. 1-3, an iron golf club head 10 incorporating features of the present invention is preferably composed of two main components, a perimeter member 12 and a face plate insert 14. The perimeter member 12 is preferably composed of a relatively dense material such as stainless steel, carbon steel, beryllium-copper, or other material having a density of least 7.0 grams per cubic centimeter. The perimeter member has a sole waIl 16, a heel wall 18 extending upwardly from heel end 20 of sole wall 16, a toe wall 22 extending upwardly from toe end 24 of sole wall 16, and a top wall 26 extending from an upper end 28 of heel wall 18 to an upper end 30 of toe wall 22. Perimeter member 12 further comprises a hosel 32 having a hosel bore 34 for receiving a golf club shaft (not shown).
10101 Face plate insert 14 is preferably formed of a core member 36 and a shell member 38 that encases core member 36. Preferably, core member 36 is composed of a material such as aluminum, thermoplastic, thermosetplastic or foam metal having a bulk density of less than 2.7 grams per cubic centimeter. Core member 36 is preferably a solid prism having substantially the same shape as finished face plate insert 14 but smaller in overall size. Core member 36 preferably has a thickness alpha (a) in the range of 0.025 to 0.040 inches, and preferably between 0.03 5 and 0.040 inches.
10111 Shell member 38 comprises a metallic coating that fully encases core member 36.
Preferably, shell member 38 comprises a nickel iron nanometal having a grain size on the order of 10 to 50 nanometers. Shell member 38 comprises a front wall 40, a rear wall 42 and a perimeter wall 44. Front wall 40 has a front surface 47 arranged for impacting a golf ball.
Preferably, front wall 40 has a thickness beta () between 0.030 and 0.050 inch, rear wall 42 has a thickness gamma (y) between 0.015 and 0.025 inch, and perimeter waIl 44 preferably has a thickness delta (6) between 0.015 to 0.030 inch.
[0121 Shell member 38 may be sintered onto core member 36 to form face plate insert 14, however, shell member 38 is preferably applied to core member 36 by an electroplating or electroforming process such as the electroplating process for applying nanometals practiced by Power Metal Technologies, Inc. of Carlsbad. California. This process applies coatings that are in excess of 0.010 inches in thickness as opposed to conventional chrome and other protective coatings which are typically less than 0.001 inch thick or less than 1% of the thickness of the part being coated. All of the thicknesses 13, y and 6 are at least 1% as thick, and preferably at least 10% as thick, as the thickness a of core member 36. As can be determined from an examination of Fig. 2, face plate insert 14 has an exceptionally high area moment of inertia as a result of the displacement between front wall 40 and rear wall 42. Consequently, a face plate insert constructed in accordance with the teachings of the present invention is lighter, stiffer and yet
more forgiving than prior art face plate inserts.
10131 Face plate insert 14 further includes a plurality of grooves 46 disposed in front wall 40. Grooves 46 are preferably U-shaped in cross-section with substantially vertical walls meeting the front surface 47 of face plate insert 14 along a fillet having a radius of 0. 010 �0.001 inch. Because front wall 40 is formed by an electrodeposition process, rather than casting, the tolerance on the U-shaped grooves 46 can be held to these close tolerances without the necessity of secondary machining.
1014) As shown in Fig. 3, face plate insert 14 may be attached to perimeter member 12 by any conventional means but in the illustrative embodiment is attached to perimeter member 12 by placing face plate insert 14 into a recess 48 formed in perimeter member 12 until it comes to rest against ledge 50. Recess 48 is formed by the sole, heel, toe and top walls 16, 18, 22 and 26, respectively, of perimeter member 12. A deformable lip 52 is then deformed until it presses against shell front wall 40 to form a crimp joint that permanently retains face plate insert 14 in place. Face plate 14 may, however, be attached by unconventional means such as nanobonding in which dissimilar metals are bonded on a submicroscopic level.
(0151 Referring to Figs. 4 and 5, the face plate insert 14 has been replaced by a face plate insert 14A. It will be understood that, in the face plate insert 14A, the core member 36A is sandwiched between front and rear walls 40A, 42A of a shell member 38A. The perimeter wall 44 of the face plate insert 14 has been removed from the face plate insert I 4A.
[016) Although certain illustrative embodiments and methods have been disclosed herein, it will be apparent from the foregoing disclosure to those skilled in the art that variations in modifications of such embodiments and methods may be made without departing from the spirit arid scope of the invention. For example, although the illustrative embodiment discloses a single solid core, multiple cores and/or hollow cores are considered within the scope of the invention. Accordingly, it is intended that the invention should be limited only to the extent required by the appended claims and the rules and principles of applicable law.
