Golf club head having internal fins for resisting structural deformation and mechanical shockwave migration

Abstract

An improved golf club head has at least one fin, rib or arch extending inside the club head structure and varying in height. The fins run along the inside of the club head perimeter structure. The fins are perpendicular to the face resulting in stiffening and strengthening of the club head, thereby resisting structural deformation and mechanical shockwave migration that occurs upon impact with the golf ball. The fins traverse the length or a portion of the length of the club head along an internal perimeter. The fins are incorporated on either the crown and/or the sole, but can be added to other portions of the club head, such as the skirt or club face should additional stiffening and strengthening be desired. The fins, can vary in size and shape and location depending on the desired stiffness and on the size, shape and material of the club head.

1 . A golf club metal wood head having an enclosed hollow interior defined by a plurality of surfaces including a crown, a sole, a face, a skirt, a toe and a heel having a hosel extending therefrom; the head comprising: 
 at least one fin member extending from said crown within said interior between said face and said skirt, said fin member having a height which is minimum adjacent said face and adjacent said skirt and which is maximum between said face and said skirt.    
   
   
       2 . The golf club metal wood head recited in  claim 1  wherein said fin member at said maximum height is tangent to a plane which intersects said crown where said crown merges with said face and said skirt.  
   
   
       3 . The golf club metal wood head recited in  claim 1  further comprising a plurality of said fin members, at least two of said fin members being parallel to each other and extending from said crown within said interior between said face and said skirt.  
   
   
       4 . The golf club metal wood head recited in  claim 3 , at least two of said fin members being parallel to each other and extending from said sole within said interior between said face and said skirt.  
   
   
       5 . The golf club metal wood head recited in  claim 3  wherein each of said fin members extending from said crown has a height which is minimum adjacent said face and adjacent said skirt and which is maximum between said face and said skirt.  
   
   
       6 . The golf club metal wood head recited in  claim 5  wherein the maximum height of each of said fin members extending from said crown is tangent to a plane which intersects said crown where said crown merges with said face and said skirt.  
   
   
       7 . The golf club metal wood head recited in  claim 4  wherein each of said fin members extending from said sole has a height which is minimum adjacent said face and adjacent said skirt and which is maximum between said face and said skirt.  
   
   
       8 . The golf club metal wood head recited in  claim 7  wherein the maximum height of each of said fin members extending from said sole is tangent to a plane which intersects said crown where said crown merges with said face and said skirt.  
   
   
       9 . A golf club metal wood head having an enclosed hollow interior defined by a plurality of surfaces including a crown, sole, a face, a skirt, a toe and a heel having a hosel extending therefrom; the head comprising: 
 at least one fin member extending from at least one of said plurality of surfaces with said interior and oriented relative to said face for resisting deformation of said crown and said sole upon impact of said face with a golf ball for promoting a greater efficiency of the transfer of force into said golf ball upon said impact    
   
   
       10 . The golf club metal wood head recited in  claim 9  wherein said fin member extends from said crown.  
   
   
       11 . The golf club metal wood head recited in  claim 9  wherein said fin member extends from said sole.  
   
   
       12 . The golf club metal wood head recited in  claim 9  wherein said fin member extends from said face.  
   
   
       13 . The golf club metal wood head recited in  claim 9  wherein said fin member has a tapered cross-section.  
   
   
       14 . The golf club metal wood head recited in  claim 9  wherein said fin member has an I-beam cross-section  
   
   
       15 . The golf club metal wood head recited in  claim 9  wherein said fin member has a uniform cross-section  
   
   
       16 . The golf club metal wood head recited in  claim 9  wherein said fin member has an arched shape.  
   
   
       17 . The golf club metal wood head recited in  claim 9  wherein said fin member has a V-shaped cross-section.  
   
   
       18 . The golf club metal wood head recited in  claim 9  wherein said fin member is formed as a V-shaped groove in said surface.
