Abstract

A golf club head with a channel sized to receive one or more adjustable weights and an external support structure that bridges, and thereby supports, the channel without unduly interfering with weight adjustment is disclosed herein. The support structure, which includes one or more stiffening members on the exterior of the golf club head, improves the sound quality of the golf club head, and is particularly useful to attenuate the lower frequency mode shapes associated with slider channel geometry in golf club heads.

First claim

We claim:

1 . A method for manufacturing a golf club head, the method comprising:
forming a body comprising a sole that defines a channel, and a support structure comprising at least one stiffening member, the support structure bridging at least a portion of the channel; wherein the at least one stiffening member comprises an Area Member representing the area of the at least one stiffening member that bridges the channel, wherein the channel comprises a Total Channel Area, wherein the support structure comprises a Total Member Area, which is equivalent to Σ i=1 n Area Member i , wherein n=the number of stiffening members, wherein

 and
wherein Member Ratio is no less than 0.001 and no greater than 1.

2 . The method according to claim 1 wherein Member Ratio is no less than 0.02 and no greater than 0.90.

3 . The method according to claim 2 wherein Member Ratio is no less than 0.10 and no greater than 0.50.

4 . The method according to claim 1 wherein the at least one stiffening member comprises a first stiffening member and a second stiffening member.

5 . The method according to claim 4 wherein the first stiffening member is disposed proximate a first end of the channel, and wherein the second stiffening member is disposed proximate a second end of the channel.

6 . The method according to claim 4 wherein the first stiffening member is spaced from a first end of the channel by a first distance, wherein the first stiffening member is spaced from the second stiffening member by a second distance, and wherein the first distance is approximately equal to the second distance.

7 . A method for manufacturing a golf club head, the method comprising:
forming a body comprising a sole that defines a channel, and a support structure comprising a plurality of planar stiffening members, the support structure bridging at least a portion of the channel; wherein each stiffening member of the plurality of planar stiffening members comprises an Area Member representing the area of each planar stiffening member that bridges the channel; wherein the channel comprises a Total Channel Area, wherein the support structure comprises a Total Member Area, which is equivalent to Σ i=1 n Area Member i , wherein n=the number of planar stiffening members, wherein

wherein Member Ratio is no less than 0.001 and no greater than 1.

8 . The method according to claim 7 wherein at least one stiffening member of the plurality of stiffening members comprises a rib extending along a longitudinal axis of the at least one stiffening member.

9 . The method according to claim 7 wherein each stiffening member of the plurality of stiffening members comprises a thickness of 0.015 to 0.150 inch.

10 . The method according to claim 7 wherein at least one stiffening member of the plurality of stiffening members bridges a midpoint of the channel.

11 . The method according to claim 7 wherein at least one stiffening member of the plurality of stiffening members has an hourglass shape.

12 . The method according to claim 7 wherein each stiffening member of the plurality of stiffening members has an hourglass shape.
