Abstract
A golf club includes a club head having a sole with an improved region. In a first soled position at which the golf club is oriented at a first lie angle, the golf club exhibits a first face angle. In a second soled position at which the golf club is oriented at a second lie angle less than the first lie angle by no less than 1 degree, the golf club exhibits a second face angle that is within 1 degree of the first face angle. And in a third soled position at which the golf club is oriented at a third lie angle greater than the first lie angle by no less than 1 degree, the golf club exhibits a third face angle that is within 1 degree of the first face angle.
Claims20
A golf club comprising:
- a shaft having a butt end and a tip end;
- and
- a club head including:
- a volume greater than 360 cubic centimeters;
- a striking face at a front portion;
- a rear portion opposite the striking face;
- a heel portion;
- a hosel portion shaped to receive therein the tip end of the shaft;
- a toe portion opposite the heel portion;
- a crown;
- and
- a sole opposite the crown, the sole configured such that:
- in a first soled position at which the golf club is oriented at a first lie angle between 40 and 60 degrees, the shaft is in a first rotational position and the golf club exhibits a first face angle;
- in a second soled position at which the golf club is oriented at a second lie angle between 40 and 60 degrees and less than the first lie angle by no less than 1 degree, the shaft is in a second rotational position, which is rotationally offset from the first rotational position in a first direction, and the golf club exhibits a second face angle that is within 1 degree of the first face angle;
- and
- in a third soled position at which the golf club is oriented at a third lie angle between 40 and 60 degrees and greater than the first lie angle by no less than 1 degree, the shaft is in a third rotational position, which is rotationally offset from the first rotational position in a second direction opposite the first direction, and the golf club exhibits a third face angle that is within 1 degree of the first face angle.
A golf club comprising:
- a shaft having a butt end and a tip end;
- a grip attached to the butt end of the shaft;
- and
- a club head including:
- a volume greater than 400 cubic centimeters;
- a striking face at a front portion;
- a rear portion opposite the striking face;
- a heel portion;
- a toe portion opposite the heel portion;
- a hosel portion shaped to receive therein the tip portion of the shaft;
- a crown;
- and
- a sole opposite the crown, the sole configured such that:
- in a first soled position at which the golf club is oriented at a first lie angle between 40 and 60 degrees, the shaft is in a first rotational position and the golf club exhibits a first face angle;
- in a second soled position at which the golf club is oriented at a second lie angle between 40 and 60 degrees and less than the first lie angle by no less than 5 degrees, the shaft is in a second rotational position, which is rotationally offset from the first rotational position in a first direction, and the golf club exhibits a second face angle that is within 0.5 degrees of the first face angle;
- and
- in a third soled position at which the golf club is oriented at a third lie angle between 40 and 60 degrees and greater than the first lie angle by no less than 5 degrees, the shaft is in a third rotational position, which is rotationally offset from the first rotational position in a second direction opposite the first direction, and the golf club exhibits a third face angle that is within 0.5 degrees of the first face angle.
