Striking Plate For A Golf Club Head

US Patent:
6338683, Jan 15, 2002
Filed:
Dec 30, 1999
Appl. No.:
09/475752
Inventors:
John B. Kosmatka - Encinitas CA
Assignee:
Callaway Golf Company - Carlsbad CA
International Classification:
A63B 5304
US Classification:
473329, 473342, 473345, 473349
Abstract:
A golf club having a club head with a striking plate that has an aspect ratio in excess of 0. 575. The golf club head has a thin striking plate with a high aspect ratio in order to increase the deflection of the striking plate during impact with a golf ball. The striking plate may be composed of stainless steel, titanium, aluminum, amorphous metal, composites, or the like. The golf club head may be a wood or an iron.

Complaint Face Golf Club

US Patent:
6348013, Feb 19, 2002
Filed:
Dec 30, 1999
Appl. No.:
09/475753
Inventors:
John B. Kosmatka - Encinitas CA
Assignee:
Callaway Golf Company - Carlsbad CA
International Classification:
A63B 5304
US Classification:
473329, 473345
Abstract:
A compliant golf club head permits a more efficient impact between a golf ball and the golf club head. By allowing a face section of the golf club head to flex rearwardly during impact with the golf ball internal stresses within the golf ball are reduced to yield a more efficient impact. A thin wall section is located generally parallel with the face and near the junction with a top, bottom heel and toe sections to allow the face of the golf club head to flex rearwardly.

Golf Club Head Having A Striking Face With Improved Impact Efficiency

US Patent:
6348015, Feb 19, 2002
Filed:
Mar 14, 2000
Appl. No.:
09/525216
Inventors:
John B. Kosmatka - Encinitas CA
Assignee:
Callaway Golf Company - Carlsbad CA
International Classification:
A63B 5304
US Classification:
473342, 473329, 473345, 473349, 473350
Abstract:
A compliant golf club head permits a more efficient impact between a golf ball and the golf club head. Material and geometry constraints of a striking plate of the golf club head can reduce energy losses caused by large strain and strain rate values of the golf ball, these constraints on the striking plate yield a measure of the impact efficiency of the golf club head. Designating a required natural frequency range of the striking plate provides improved impact efficiency between the golf ball the golf club head.

Golf Club Head

US Patent:
6364789, Apr 2, 2002
Filed:
Dec 30, 1999
Appl. No.:
09/475754
Inventors:
John B. Kosmatka - Encinitas CA
Assignee:
Callaway Golf Company - Carlsbad CA
International Classification:
A63B 5304
US Classification:
473329, 473342, 473345
Abstract:
A golf club having a club head with a striking plate and an annular deflection enhancement member isolating the striking plate from the body of the golf club head. The annular deflection enhancement member is composed of a material having a Youngs Modulus lower than that of the material of the striking plate. Thus, the striking plate may be composed of steel while the annular deflection enhancement member is composed of titanium.

Compliant Polymer Face Golf Club Head

US Patent:
6390932, May 21, 2002
Filed:
Apr 18, 2000
Appl. No.:
09/551284
Inventors:
John B. Kosmatka - Encinitas CA
David L. Felker - Bonsall CA
Pijush Dewanjee - Oceanside CA
Assignee:
Callaway Golf Company - Carlsbad CA
International Classification:
A63B 5304
US Classification:
473324, 473326, 473329, 473349, 473350
Abstract:
A golf club head having a face section with a polymer surface can provide a more efficient impact between a golf ball and the golf club head. By utilizing a polymer surface with desired material properties of stress, strain and damping levels, the face section will incur higher strain and strain rate levels than the golf ball. These lower internal stresses within the golf ball yield a more efficient impact with a golf club head.

Contoured Golf Club Face

US Patent:
6413169, Jul 2, 2002
Filed:
Nov 9, 2001
Appl. No.:
09/683028
Inventors:
John B. Kosmatka - Encinitas CA
Assignee:
Callaway Golf Company - Carlsbad CA
International Classification:
A63B 5304
US Classification:
473329, 473345, 473349, 473224
Abstract:
A contoured golf club face providing increased structural integrity for a given weight and size is described and shown along with a method for its design. The contoured golf club face includes a vertical stiffening region, a tapered horizontal stiffening region, four similar contoured quadrants of increasingly thinning material toward the center of each quadrant, and thickening regions at face/sole and face/crown intersection regions. The thicknesses of adjoining regions are gradually blended to provide a smooth contoured surface. The present golf club face is light weight, is structurally resistant to impact deformation, is resistant to initial and long-term failure, has its mass center located at its sweet spot, exhibits inertial axes which are aligned with vertical and horizontal axes (i. e. primary club force directions: ball impact force and club centrifugal force directions), and produces acoustical tones. A club incorporating the present contoured golf club face may provide a certain first acoustical sound when used to hit a ball with a certain first specific area of the face (e. g.

Golf Club Head With Coated Striking Plate

US Patent:
6428427, Aug 6, 2002
Filed:
Oct 3, 2000
Appl. No.:
09/678942
Inventors:
John B. Kosmatka - Encinitas CA
Assignee:
Callaway Golf Company - Carlsbad CA
International Classification:
A63B 5304
US Classification:
473349, 473342, 473331, 473330
Abstract:
A golf club head ( ) having a thin striking plate ( ) with a smooth exterior surface and a thin layer ( ) disposed on the exterior surface ( ). The thin layer ( ) has a plurality of scorelines ( ) that absorb the shock during impact with a golf ball. The striking plate ( ) has a thickness in the range of 0. 010 inch to 0. 200 inch, and the thin layer ( ) has a thickness in the range of 0. 003 inch to 0. 050 inch. The striking plate ( ) may have a uniform thickness or a variable thickness.
