Top weighted putter head

Abstract

A club head for a golf putter including upper and lower sections where the upper section has a mass greater than a mass of the bottom section and where the upper section of the club head includes an entire top surface, an upper perimeter of the club, and a portion extending into a front striking face of the lower club head. The upper section may also include a portion extending from the front striking face into the sole, a portion extending from the upper, rear perimeter portion to a lower, rear perimeter portion, and/or a portion extending from the lower, rear perimeter portion to the sole. The lower section comprises the part of the club head which is other than the upper section part and includes lower perimeter sections of the club. The upper and lower sections mate to form a club head having a hollow, interior core.

1 . A golf putter head, comprising: 
 a putter head body including an upper section made of a first material and having a first mass, and a lower section made of a second material and having a second mass less than said first mass, said upper section including an entire top surface of said putter head body and a front surface portion of said putter head body, said lower section including a portion of a sole of said putter head body, wherein said upper and lower sections extend at least partially about a perimeter of said putter head body and form a cavity there between.    
   
   
       2 . The golf putter head of  claim 1  wherein said upper section extends about an upper perimeter of said putter head body, and across a rear, lower perimeter portion into another portion of said sole of said putter head body.  
   
   
       3 . The golf putter head of  claim 2  wherein said lower section extends about a lower perimeter of said putter head body except about the rear, lower perimeter portion where said upper section extends and wherein said lower section extends into front surface portions other than said upper section front surface portion.  
   
   
       4 . The golf putter head of  claim 1  wherein said upper section extends from said front surface portion into another portion of said sole of said putter head body.  
   
   
       5 . The golf putter head of  claim 1  wherein said front surface portion is integral with said top surface.  
   
   
       6 . The golf putter head of  claim 1  wherein said front surface portion is an insert.  
   
   
       7 . The golf putter head of  claim 1  wherein said first material is stainless steel and said second material is aluminum.  
   
   
       8 . The golf putter head of  claim 1  wherein a central region of said front surface portion includes a balance point.  
   
   
       9 . The golf putter head of  claim 8  wherein said balance point is ¼ of an inch from a top of said face.  
   
   
       10 . The golf putter head of  claim 8  wherein said balance point ranges from ⅛ of an inch to ⅜ of an inch from a top of said face.  
   
   
       11 . The golf putter head of  claim 1  wherein a balance point of said top surface is in a central region of said top surface and ranges from ¾ of an inch to 1½ inches from a front of said top surface.  
   
   
       12 . The golf putter head of  claim 1  wherein a lower length of said front surface portion ranges from ¾ of an inch to 3¾ inches.  
   
   
       13 . The golf putter head of  claim 1  wherein said head weighs 350 grams.  
   
   
       14 . The golf putter head of  claim 13  wherein said upper section weighs 270 grams and said lower section weighs 80 grams.  
   
   
       15 . The golf putter head of  claim 1  wherein about 60% of a mass of the golf putter head strikes a golf ball on its equator or above when the golf putter head has a ground clearance of about 1 inch plus about ½ a diameter of the golf ball.  
   
   
       16 . The golf putter head of  claim 1  wherein said upper and lower sections include an opening configured to receive a shaft.  
   
   
       17 . A golf putter head comprising: 
 an upper component having a hollow interior, and a lower component having a hollow interior, said upper component having a first mass and said lower component having a second mass less than said first mass, wherein said upper component includes a front striking face of said golf putter head extending into a front, recessed area of said lower component, a rear portion of said golf putter head extending into a rear, recessed area of said lower component, a thin sole portion extending from said front striking face into said front recessed area, and another thin sole portion extending from said rear portion into said rear, recessed area, and wherein said lower section comprises portions other than said upper component.    
   
   
       18 . A club head for a golf putter, comprising: 
 a body having a top and a bottom wherein said top has a greater mass than said bottom and said top includes an entire top surface of said body portion and extends into an upper perimeter of said body and a front surface portion of said body.    
   
   
       19 . The club head of  claim 18  wherein said top extends into a rear, lower perimeter portion of said body.  
   
   
       20 . The club head of  claim 19  wherein said front surface of said top extends into a sole portion, said rear, lower perimeter portion extends into another sole portion, and said bottom extends into said remaining perimeter, sole, and front surface portions.  
   
   
       21 . The club head of  claim 18  wherein said body portion includes a hollow core.  
   
   
       22 . The club head of  claim 18  is wherein said top is comprised of a first material having a first density and said bottom is comprised of a second material having a second density less than said first density.
