Golf clubs and golf club heads

Abstract

Wood-type golf clubs and/or golf club heads include a club head body having a breadth to length ratio of at least 0.9, optionally a club head volume of at least 450 cubic centimeters, and a diagonal dimension of at least 75% of a theoretical maximum diagonal dimension (as measured along a diagonal of a bounding box enclosing the club head body and defined by the length dimension and the breadth dimension). In some examples, the diagonal dimension may be at least 80%, 85%, or even 90% of the theoretical maximum diagonal dimension. Additionally or alternatively, if desired, at least one horizontal cross section of the club head body will enclose or encompass an area of at least 0.8×BL, at least 0.85×BL, at least 0.9×BL, or even at least 0.95×BL.

       4 . A golf club head according to  claim 2 , wherein the at least one non-metal portion includes a non-metal sole portion. 
   
   
       5 . A golf club head according to  claim 2 , wherein the club head body includes a metal member, wherein the at least one non-metal portion is engaged with the metal member. 
   
   
       6 . A golf club head according to  claim 1 , further comprising:
 a weight member engaged with the club head body and located at or proximate to a rear portion of the club head body.   
   
   
       7 . A golf club head according to  claim 1 , further comprising:
 a weight member removably engaged with the club head body.   
   
   
       8 . A golf club head according to  claim 1 , further comprising:
 a weight member engaged with the club head body and located within an interior chamber at least partially defined by the club head body.   
   
   
       9 . A golf club head according to  claim 1 , further comprising:
 a first weight member engaged with the club head body at or proximate to the rear portion of the club head body; and   a second weight member engaged with the club head body at or proximate to a rear portion of the club head body, wherein the second weight member is separate from the first weight member.   
   
   
       10 . A golf club head according to  claim 9 , wherein the first weight member and the second weight member have different masses. 
   
   
       11 . A golf club head according to  claim 9 , wherein the first weight member is removably engaged with the club head body and the second weight member is removably engaged with the club head body. 
   
   
       12 . A golf club head according to  claim 1 , further comprising:
 a weight engaged with or integrally formed at or proximate to a rear portion of the golf club head body;   wherein the weight includes a first weight portion engaged with or integrally formed at or proximate to the rear portion of the club head body, and a second weight portion engaged with or integrally formed at or proximate to the rear portion of the club head body, wherein the second weight portion is separate from the first weight portion;   further wherein the first weight portion is located toward a heel side of the rear portion of the club head body and the second weight portion is located toward a toe side of the rear portion of the club head body.   
   
   
       13 . A golf club head, comprising:
 a club head body having a club head length dimension L of at least 4.6 inches, and a club head breadth dimension B of at least 4.4 inches, wherein the club head body has a breadth dimension to length dimension ratio of at least 0.94 and less than 1.0 and a club head volume of at least 450 cubic centimeters, and wherein at least one horizontal cross section of the club head body encloses an area of at least 0.8×BL.   
   
   
       14 . A golf club head according to  claim 13 , wherein the area is at least 0.85×BL. 
   
   
       15 . A golf club head according to  claim 13 , wherein the area is at least 0.9×BL. 
   
   
       16 . A golf club head according to  claim 13 , wherein the club head body includes at least one non-metal portion. 
   
   
       17 . A golf club head according to  claim 16 , wherein the at least one non-metal portion includes a non-metal crown portion. 
   
   
       18 . A golf club head according to  claim 16 , wherein the at least one non-metal portion includes a non-metal sole portion. 
   
   
       19 . A golf club head according to  claim 16 , wherein the club head body includes a metal member, wherein the at least one non-metal portion is engaged with the metal member. 
   
   
       20 . A golf club, comprising:
 a club head body having a club head length dimension L of at least 4.6 inches and a club head breadth dimension B of at least 4.4 inches, wherein the club head body has a breadth dimension to length dimension ratio of at least 0.94 and less than 1.0, a club head volume of at least 450 cubic centimeters, and an overall diagonal dimension of at least 0.75×(B 2 +L 2 ) 1/2 , wherein the overall diagonal dimension is measured along a diagonal of a bounding box enclosing the club head and defined by the length dimension and the breadth dimension; and   a shaft member engaged with the club head body.
