Abstract
A golf club head includes a face portion including a hitting face, a sole portion, a crown portion, and a hosel portion. The sole portion includes a center thin-wall part and an outer thick-wall part that is formed on a sole outer edge side of the center thin-wall part and is thicker than the center thin-wall part. The outer thick-wall part includes a first thick-wall part that is formed over a region including a position of a center of gravity of the head in a face-back direction, and a second thick-wall part that is positioned on a back side of the first thick-wall part and is thicker than the first thick-wall part. The outer thick-wall part of the sole portion may further include a third thick-wall part that is positioned on the back side of the second thick-wall part and is thinner than the second thick-wall part.
Claims22
A golf club head comprising:
- a face portion that includes a hitting face;
- a sole portion, wherein a wall thickness of the sole portion is variable at different positions of the sole portion;
- a crown portion;
- and
- a hosel portion, wherein
- the sole portion comprises:
- a thin-wall part disposed at a central region of the sole portion, the central region including a geometric center of the sole portion, the geometric center of the sole portion being defined as a center of figure of the golf club head in a bottom view of the golf club head;
- a thick-wall part disposed at an outer portion of the sole portion between the thin-wall part and an outer edge of the sole portion, a wall thickness of the thick-wall part being greater than a wall thickness of the thin-wall part;
- and
- a face vicinity part that is located between the thin-wall part and the face portion, that extends along the face portion, and that has a wall thickness smaller than the wall thickness of the thick-wall part,
- the thick-wall part extends continuously from a toe-side position relative to the thin-wall part, through a back-side position relative to the thin-wall part, to a heel-side position relative to the thin-wall part,
- the thick-wall part includes a gap at a face-side position relative to the thin-wall part, and
- the thin-wall part is connected to the face vicinity part at a position where the gap is located.
A golf club head comprising:
- a face portion that includes a hitting face;
- a sole portion, wherein a wall thickness of the sole portion is variable at different positions of the sole portion;
- a crown portion;
- and
- a hosel portion, wherein
- the sole portion comprises:
- a thin-wall part disposed at a central region of the sole portion, the central region including a geometric center of the sole portion, the geometric center of the sole portion being defined as a center of figure of the golf club head in a bottom view of the golf club head;
- a thick-wall part disposed at an outer portion of the sole portion between the thin-wall part and an outer edge of the sole portion, a wall thickness of the thick-wall part being greater than a wall thickness of the thin-wall part;
- a face vicinity part that is located between the thin-wall part and the face portion, that extends along the face portion, and that has a wall thickness smaller than the wall thickness of the thick-wall part;
- and
- a port,
- the thick-wall part extends continuously from a toe-side position relative to the thin-wall part, through a back-side position relative to the thin-wall part, to a heel-side position relative to the thin-wall part,
- the thick-wall part includes a gap at a face-side position relative to the thin-wall part, and
- the thin-wall part is connected to the face vicinity part at a position where the gap is located.
A golf club head formed by joining a face member to a head body, the golf club head comprising:
- a face portion that includes a hitting face;
- a sole portion, wherein a wall thickness of the sole portion is variable at different positions of the sole portion;
- a crown portion;
- and
- a hosel portion, wherein
- the sole portion comprises:
- a thin-wall part disposed at a central region of the sole portion, the central region including a geometric center of the sole portion, the geometric center of the sole portion being defined as a center of figure of the golf club head in a bottom view of the golf club head;
- a thick-wall part disposed at an outer portion of the sole portion between the thin-wall part and an outer edge of the sole portion, a wall thickness of the thick-wall part being greater than a wall thickness of the thin-wall part;
- and
- a face vicinity part that is located between the thin-wall part and the face portion, that extends along the face portion, and that has a wall thickness smaller than the wall thickness of the thick-wall part,
- the thick-wall part extends continuously from a toe-side position relative to the thin-wall part, through a back-side position relative to the thin-wall part, to a heel-side position relative to the thin-wall part,
- the thick-wall part includes a gap at a face-side position relative to the thin-wall part,
- the thin-wall part is connected to the face vicinity part at a position where the gap is located,
- the face member comprises:
- a base portion that constitutes a face portion;
- and
- a backward extending portion that extends backward from a peripheral edge of the base portion,
- the backward extending portion comprises:
- a crown forming portion that constitutes a part of the crown portion;
- and
- a sole forming portion that constitutes a part of the sole portion.
