Golf putter heads

Abstract

A golf putter head generally includes a first striking surface, a second surface extending above the first striking surface, a third surface extending rearwardly behind the first striking surface, and indicators for indicating to a user when the user's head is at a predetermined position relative to the golf putter head.

1 . A golf putter head comprising a first striking surface, a second surface extending above the first striking surface, a third surface extending rearwardly behind the first striking surface, at least one sidewall extending upwardly from the third surface and defining a cavity behind the first striking surface, the sidewall including an indicator within the cavity that is not visible to a user when the user's head is at a predetermined position relative to the golf putter head, thereby indicating to the user when the user's head is at the predetermined position relative to the golf putter head.  
   
   
       2 . The golf putter head of  claim 1  wherein the second indicator comprises a portion of the sidewalls having a color different than adjacent portions of the sidewalls.  
   
   
       3 . The golf putter head of  claim 1  wherein the second indicator is not visible to the user when looking substantially straight down at the golf putter head.  
   
   
       4 . The golf putter head of  claim 1  wherein the third surface includes a second indicator for aligning the first striking surface with a golf ball.  
   
   
       5 . The golf putter head of  claim 1  wherein at least a portion of the second surface extending above the first striking surface is reflective for reflecting an image of at least a portion of a golf ball to the user when the first striking surface is positioned adjacent the golf ball.  
   
   
       6 . The golf putter head of  claim 1  wherein the cavity is generally U-shaped.  
   
   
       7 . The golf putter head of  claim 1  wherein the golf putter head includes a higher center of gravity than a golf ball.  
   
   
       8 . A golf putter head comprising a first striking surface, a second surface extending above the first striking surface, a third surface extending rearwardly behind the first striking surface and including a first indicator having a first primary color, and a second light-transmissible indicator disposed above the first indicator, the second indicator having a second primary color that when combined with the first primary color forms a secondary color, the first and second indicators cooperating with one another such that a user sees the first and second indicators as having the secondary color when the user's head is at a predetermined position relative to the golf putter head, thereby indicating to the user when the user's head is at the predetermined position relative to the golf putter head.  
   
   
       9 . The golf putter head of  claim 8  wherein the first and second indicators appear as a single indicator having the secondary color to the user when the user is looking substantially straight down at the golf putter head.  
   
   
       10 . The golf putter head of  claim 8 , wherein the second indicator is translucent.  
   
   
       11 . The golf putter head of  claim 8  further comprising a plurality of interchangeable indicators each having a different color to thereby enable the user to customize the golf putter head with a particular color scheme.  
   
   
       12 . The golf putter head of  claim 8  wherein at least a portion of the second surface extending above the first striking surface is reflective for reflecting an image of at least a portion of a golf ball to the user when the first striking surface is positioned adjacent the golf ball.  
   
   
       13 . The golf putter head of  claim 8  wherein the golf putter head includes a higher center of gravity than a golf ball.  
   
   
       14 . A golf putter head comprising a first striking surface, a second surface extending above the first striking surface, a third surface extending rearwardly behind the first striking surface and including an image, and a lens disposed above the image such that the image viewed through the lens is only in focus when the user's head is at a predetermined position relative to the golf putter head, thereby indicating to the user when the user's head is at the predetermined position relative to the golf putter head.  
   
   
       15 . The golf putter head of  claim 14  wherein the image viewed through the lens is only in focus when the user is looking substantially straight down at the putter head.  
   
   
       16 . The golf putter head of  claim 14  wherein at least a portion of the second surface extending above the first striking surface is reflective for reflecting an image of at least a portion of a golf ball to the user when the first striking surface is positioned adjacent the golf ball.  
   
   
       17 . The golf putter head of  claim 14  wherein the golf putter head includes a higher center of gravity than a golf ball.  
   
   
       18 . A golf putter head comprising a first striking surface, a second surface extending above the first striking surface, a third surface extending rearwardly behind the first striking surface, and first and second indicators including corresponding image portions which cooperate to form an image when a user's head is at a predetermined position relative to the golf putter head, thereby indicating to the user when the user's head is at the predetermined position relative to the golf putter head.  
   
   
       19 . The golf putter head of  claim 18  wherein the first and second indicators cooperate to form the image only when the user is looking substantially straight down at the golf putter head.  
   
   
       20 . The golf putter head of  claim 18  further comprising a colored portion disposed under the third surface and behind the first striking surface, the colored portion having a color different than the first and second indicators that is not visible when the first and second indicators are cooperating to form the image.  
   
   
       21 . The golf putter head of  claim 18  wherein the second indicator is disposed at a top portion of the third surface.  
   
   
       22 . The golf putter head of  claim 21  wherein the second indicator is configured to reflect an image of at least a portion of a golf ball to the user when the first striking surface is positioned adjacent the golf ball.  
   
   
       23 . The golf putter head of  claim 18  wherein at least a portion of the second surface extending above the first striking surface is reflective for reflecting an image of at least a portion of a golf ball to the user when the first striking surface is positioned adjacent the golf ball.  
   
   
       24 . The golf putter head of  claim 18  wherein the golf putter head includes a higher center of gravity than a golf ball.  
   
   
       25 . A golf putter head comprising a striking surface, a reflective translucent surface extending above the striking surface for reflecting an image of at least a portion of a golf ball to a user when the striking surface is positioned adjacent the golf ball, and an alignment surface extending rearwardly behind the striking surface, the alignment surface including at least one indicator positioned relative to the reflective translucent surface such that the indicator is visible through the reflective translucent surface and coincides with the reflected image of at least a portion of the golf ball on the reflective translucent surface when the striking surface is aligned with the golf ball and the user's head is at a predetermined position relative to the golf putter head.
