Abstract
A golf club head includes a body having a heel portion, a toe portion, a sole portion, and an outer surface, a strikeface having a geometric center, a head center of gravity, and a weight member including a weight pad. The weight member is configured to be repositionable by the user to a first position or a second position. The club head having the weight member in the first position shifts the head center of gravity toward the strikeface, and the club head having the weight member in the second position shifts the head center of gravity away from the strikeface.
Claims20
A golf club head comprising:
- a body having a heel portion, a toe portion, a sole portion, and an outer surface;
- a strikeface having a geometric center;
- a head center of gravity;
- and
- a weight member including a weight pad, wherein
- the weight member is configured to be positioned adjacent to the sole portion of the club head, substantially flush with the outer surface of the body, and
- the weight member is repositionable by the user to a first position or a second position, wherein
- the club head having the weight member in the first position shifts the head center of gravity toward the strikeface, and
- the club head having the weight member in the second position shifts the head center of gravity away from the strikeface, such that on impact with a golf ball at the geometric center of the strikeface, the club head having the weight member in the first position applies a first vertical spin on the golf ball and the club head having the weight member in the second position applies a second vertical spin on the golf ball such that the second vertical spin is different than the first vertical spin.
A golf club head comprising:
- a body having a heel portion, a toe portion, a sole portion, and an outer surface;
- a strikeface having a geometric center;
- a head center of gravity;
- and
- a weight member having opposing first and second edges and including a weight member axis and a geometric center, the weight member axis intersecting the first and second edges and the geometric center, wherein a width of the weight member in a direction taken orthogonal to the weight member axis increases along the weight member axis from the geometric center towards the first and second edges.
A golf club head comprising:
- a body having a heel portion, a toe portion, a sole portion, and an outer surface;
- a strikeface having a geometric center;
- a rear portion opposite the strikeface;
- a head center of gravity;
- a club head axis that extends through the head center of gravity from the strikeface to the rear portion;
- and
- a weight member including a weight pad, the weight pad having a center of gravity, wherein the weight member is configured to be positioned adjacent to the sole portion of the club head in one of a first position or a second position, wherein the position of the weight pad center of gravity changes in relation to the strikeface between the first and second positions, wherein a weight pad axis fixed with respect to the club head axis extends through the weight pad center of gravity when the weight member is in the first position and when the weight member is in the second position, and wherein the weight pad axis and the club head axis form a weight pad angle that ranges from 0 degrees to 20 degrees.
