Wood-type golf club head

Abstract

According to one embodiment, a wood-type golf club head includes: a face portion; a sole portion; a crown portion; a leading edge defined between the face portion and the sole portion; an upper edge defined between the face portion and the crown portion; wherein, at a basic state that the golf club head is set on a horizontal plane, a contact point between the horizontal plane and the sole portion is defined as a ground point, wherein a plane passing through the ground point and extending in a direction of a target line is defined as a vertical plane, wherein a height from the horizontal plane to a first intersection point where the face upper edge intersects the vertical plane is defined as a face height H 1, and wherein a height H 3 from the horizontal plane to a second intersection point where the vertical plane intersects the leading edge is defined in a range between ⅓ and ½ of the face height H 1.

1 . A wood-type golf club head comprising:
 a face portion;   a sole portion;   a crown portion;   a leading edge defined between the face portion and the sole portion;   an upper edge defined between the face portion and the crown portion;   wherein, at a basic state that the golf club head is set on a horizontal plane, a contact point between the horizontal plane and the sole portion is defined as a ground point,   wherein a plane passing through the ground point and extending in a direction of a target line is defined as a vertical plane,   wherein a height from the horizontal plane to a first intersection point where the face upper edge intersects the vertical plane is defined as a face height H 1 , and   wherein a height H 3  from the horizontal plane to a second intersection point where the vertical plane intersects the leading edge is defined in a range between ⅓ and ½ of the face height H 1 .   
   
   
       2 . The wood-type golf club head according to  claim 1 , wherein the height H 3  is defined in a range between ⅙ and ½ of the face height H 1 . 
   
   
       3 . The wood-type golf club head according to  claim 1 , wherein the height H 3  is defined in a range between ⅛ and ½ of the height H 1 . 
   
   
       4 . The wood-type golf club head according to  claim 1 , wherein a third intersection point where the face portion intersects a perpendicular line drawn from a center of gravity of the golf club head onto the face portion is lower than a face center FC of the face portion, the face center FC being defined as
     FC =( H 1− H 3)/2+ H 3.   
   
   
       5 . The wood-type golf club head according to  claim 1  further comprising a chamfer portion formed between the leading edge and the sole portion,
 wherein the sole portion includes a first sole portion and a second sole portion including the ground point,   wherein a height H 0  from the horizontal plane to the ground point is lower than a height H 4  from the horizontal plane to a lowermost portion of the first sole portion, and   wherein the height H 0  is lower than a height from the horizontal plane to a lowermost point of the chamfered portion;   
   
   
       6 . The wood-type golf club head according to  claim 5 , wherein the height H 4  is in a range from 5 mm to 20 mm. 
   
   
       7 . The wood-type golf club head according to  claim 5 , wherein a height H 5  from the leading edge to the lowermost portion of the first sole portion is in a range from 2 mm to 5 mm. 
   
   
       8 . The wood-type golf club head according to  claim 5 , wherein the chamfered portion is extend downward from the leading edge and in a direction opposite to the target line direction.
