Abstract

A golf club head includes a club head body having a striking face and at least one float weight housed in a chamber defined by the club head body. The chamber has an impact wall portion, and the at least one float weight is freely movable within the chamber. The at least one float weight moves between a first position, spaced from the impact wall portion, and a second position in contact with the impact wall portion while the striking face is impacting a golf ball.

Claims

exact text as granted — not AI-modified
1 . A golf club head comprising:
 a club head body having a striking face, the club head body comprising multiple float weight chambers each having an impact wall portion common with the striking face; and   at least one float weight housed in each float weight chamber, the at least one float weight being freely movable within its respective float weight chamber;   wherein each float weight moves between a first position, spaced from the impact wall portion, and a second position in contact with the impact wall portion while the striking face is impacting a golf ball; and   wherein each float weight chamber has a side wall aligned at an angle of less than 90° with respect to the striking face of the club head body.   
     
     
         2 . The golf club head of  claim 1 , wherein the club head body defines at least one non-float weight chamber on a side opposite of the striking face with respect to the float weight chambers. 
     
     
         3 . (canceled) 
     
     
         4 . The golf club head of  claim 1 , wherein at least one chamber is substantially hexahedron shaped. 
     
     
         5 . The golf club head of  claim 1 , wherein the at least one float weight moves between the first position and the second position within 24 microseconds. 
     
     
         6 . The golf club head of  claim 1 , wherein the surfaces of each chamber has a coefficient of friction of less than 0.3. 
     
     
         7 . The golf club head of  claim 6 , wherein the surfaces of at least one chamber is treated with a fluoropolymer. 
     
     
         8 . The golf club head of  claim 1 , wherein the float weight comprises mercury. 
     
     
         9 . The golf club head of  claim 1 , wherein the float weight comprises steel. 
     
     
         10 - 14 . (canceled) 
     
     
         15 . The golf club head of  claim 1 , wherein at least one chamber is ellipsoid shaped. 
     
     
         16 - 20 . (canceled)
