Golf club head with multi-component construction

Abstract

The invention relates to a golf club head with multi-component construction. The golf club head includes a hollow body that is created from components constructed of different materials so that the weight distribution may be optimized.

1 . A golf club head, comprising:
 a crown, a sole, and a face defining a body, wherein the body includes at least one insert component connected to the body at an attachment perimeter,   wherein the attachment perimeter comprises a flange comprising a hole in a surface of the flange.   
     
     
         2 . The golf club head of  claim 1 , wherein the hole goes through the flange. 
     
     
         3 . The golf club head of  claim 1 , wherein the flange comprises a plurality of holes. 
     
     
         4 . The golf club head of  claim 1 , wherein the flange is formed in the body and configured to be concealed from the outside of an assembled club head by the insert component. 
     
     
         5 . The golf club head of  claim 1 , wherein the insert component is in the sole. 
     
     
         6 . The golf club head of  claim 1 , wherein the flange is an L-shaped flange protruding substantially perpendicular to a surrounding area of the body. 
     
     
         7 . The club head of  claim 3 , wherein the plurality of holes are pinpoint holes having an average aperture area between about 0.01 mm 2  and about 1 mm 2 . 
     
     
         8 . The club head of  claim 3 , wherein an area of the flange includes the plurality of holes such that a ratio of aperture space to total surface area of the area is between about 0.1 and about 0.75. 
     
     
         9 . The club head of  claim 3 , wherein the flange has a number N of holes per cm measured in a linear direction along the attachment perimeter and N is between about 10 and about 500. 
     
     
         10 . The club head of  claim 3 , wherein the flange has a number N of holes per cm measured in a linear direction along the attachment perimeter and N is between about 0.1 and about 9. 
     
     
         11 . The club head of  claim 1 , wherein the hole has a perimeter that substantially approximates a shape that is one selected from the list consisting of circular, hexagonal, rectangular, oval, elliptical, star-shaped, and irregular. 
     
     
         12 . The club head of  claim 3 , wherein the plurality of holes is disposed to be visible from the exterior of an assembled club head. 
     
     
         13 . The club head of  claim 12 , wherein the plurality of holes are filled with a translucent material. 
     
     
         14 . A component for a golf club head, comprising:
 material shaped to matingly couple to at least one other component to form a body of a club head and comprising a flange,   wherein the flange comprises at least one hole through it.   
     
     
         15 . The component of  claim 14 , wherein the flange comprises a plurality of holes. 
     
     
         16 . The component of  claim 14 , wherein the flange is an L-shaped flange protruding substantially perpendicular to a surrounding area of the component. 
     
     
         17 . The component of  claim 15 , wherein the plurality of holes have an average aperture area between about 0.1 mm 2  and about 1 cm 2 . 
     
     
         18 . The club head of  claim 15 , wherein an area of the flange includes the plurality of holes such that a ratio of aperture space to total surface are of the area is between about 0.01 and about 0.95. 
     
     
         19 . The club head of  claim 15 , wherein an area of the flange includes the plurality of holes such that a ratio of aperture space to total surface are of the area is between about 0.2 and about 0.5. 
     
     
         20 . The club head of  claim 3 , wherein the flange has a number N of holes per cm measured in a linear direction along the attachment perimeter and N is between about 10 and about 500.
