Abstract

A modular golf club head with an improved weight assembly is disclosed herein. In accordance with the presently disclosed technology, the golf club head may include a body. The body may include a face, a back, and a cavity. The modular golf club head may include a weight assembly that includes a vertical track, a movable weight installable within the vertical track and movable therein, and an adjustable clamp.

Claims (58)

1 . A modular golf club head comprising:

a body comprising:

a face;

a back extending rearward from at least a part of the face; and

a cavity between the face and the back;

a toe comprising a toe through hole to receive a fastener; and

a weight assembly within the cavity comprising:

a vertical track extending from a top of the body to a bottom of the body;

a movable weight installable within the vertical track and movable therein; and

an adjustable clamp to secure the movable weight to a discrete selectable position along the vertical track, wherein the adjustable clamp clamps in a direction perpendicular to a vertical direction on the vertical track.

2 . The modular golf club head of claim 1 , wherein the vertical track comprises notches to provide discrete selectable positions for the movable weight along the vertical track, and wherein the movable weight comprises a protrusion to engage the notches to help fix the movable weight into the discrete selectable positions.

3 . The modular golf club head of claim 1 , wherein the vertical track comprises:

a first track corner having a first track angle measured from a y-axis toward an x-axis; and

a second track corner having a second track angle measured from the y-axis toward the x-axis.

4 . The modular golf club head of claim 3 , wherein the first track angle is about 90 degrees, and wherein the second track angle is about 30 degrees.

5 . The modular golf club head of claim 3 , wherein the movable weight comprises:

a first weight corner to engage the first track corner, wherein the first weight corner has a first weight angle measured from the y-axis toward the x-axis; and

a second weight corner to engage the second track corner, wherein the second weight corner has a second weight angle measured from the y-axis toward the x-axis.

6 . The modular golf club head of claim 5 , wherein the first weight angle is about 30 degrees, and wherein the second weight angle is about 30 degrees.

7 . The modular golf club head of claim 1 , wherein the adjustable clamp comprises a clamping protrusion providing a pivot point for the adjustable clamp to engage the movable weight.

8 . The modular golf club head of claim 1 , wherein the weight assembly further comprises a fastener to fasten the movable weight into the discrete selectable position, wherein the fastener comprises a fastener axis that is perpendicular to the vertical direction.

9 . The modular golf club head of claim 1 , wherein the adjustable clamp wraps around a rearward end of the vertical track, and wherein the adjustable clamp comprises a clamping end to fit on a heelward side of the vertical track, and wherein the vertical track comprises an opening to receive the clamping end.

10 . The modular golf club head of claim 9 , wherein the weight assembly further comprises a fastener to fasten the movable weight into the discrete selectable position, wherein the fastener directly engages a part of the movable weight to fasten the movable weight into the discrete selectable position, and wherein the adjustable clamp comprises a clamping through hole to receive the fastener.

11 . The modular golf club head of claim 1 , wherein the adjustable clamp comprises:

a clamping through hole to receive a fastener; and

a clamping end to engage the movable weight.

12 . The modular golf club head of claim 11 , wherein the vertical track comprises an opening to receive at least a portion of the clamping end to secure the movable weight into the discrete selectable position by fastening the fastener.

13 . A modular golf club head comprising:

a body comprising:

a face; and

a back extending rearward from at least a part of the face; and

a cavity between the face and the back;

a toe comprising a toe through hole to receive a fastener; and

a weight assembly comprising:

a vertical track extending from a top of the body to a bottom of the body, wherein the vertical track comprises an opening;

a movable weight installable within the vertical track and movable therein;

an adjustable clamp to secure the movable weight to a discrete selectable position along the vertical track, wherein the adjustable clamp wraps around a rearward end of the vertical track, and wherein the adjustable clamp comprises:

a clamping through hole to receive the fastener; and

a clamping end to engage a part of the movable weight to secure the movable weight into the discrete selectable position along the vertical track; and

the fastener to secure the adjustable clamp.

14 . The modular golf club head of claim 13 , wherein the adjustable clamp clamps in a direction perpendicular to a vertical direction on the vertical track.

15 . The modular golf club head of claim 13 , wherein a fastener axis is perpendicular to a vertical direction of the vertical track.

16 . A modular golf club head comprising:

a body comprising:

a face;

a back extending rearward from at least a part of the face; and

a cavity between the face and the back;

a toe comprising a toe through hole to receive a fastener; and

a weight assembly comprising:

a vertical track extending from a top of the body to a bottom of the body, wherein the vertical track comprises an opening;

a movable weight installable within the vertical track and movable therein, wherein the movable weight is movable along the vertical track;

an adjustable clamp to secure the movable weight to a discrete selectable position along the vertical track, wherein the adjustable clamp comprises:

a clamping through hole; and

a clamping end to engage the movable weight; and

a fastener to secure the movable weight into the discrete selectable position;

wherein the opening receives at least a portion of the clamping end to secure the movable weight into the discrete selectable position by fastening the fastener.

17 . The modular golf club head of claim 16 , wherein the adjustable clamp clamps in a direction perpendicular to a vertical direction on the vertical track.

18 . The modular golf club head of claim 16 , wherein a fastener axis is perpendicular to a vertical direction of the vertical track.
