GOLF CLUB HEAD

摘要

A golf club head comprises a sole, a recessed sole port in the sole; and a rotatably adjustable sole piece adapted to be at least partially received within the sole port and comprising a central body having a plurality of contact surfaces adapted to contact the sole port and being offset from each other along a central axis extending through the central body of the sole piece. The sole piece can be positioned at least partially within the sole port at five or more rotational and axial positions with respect to the central axis, wherein at each rotational position, at least one of said contact surfaces of the central body contacts the sole port to set the axial position of the sole piece. The sole port and/or the sole piece can be generally pentagonal in shape.

1. A golf club head comprising:
a body having a face, a crown, a hosel, and a sole together defining an interior cavity; the body having a channel located on the sole; at least one ledge extending within the channel; at least one weight member movably positioned within the channel such that a position of the at least one weight member within the channel is able to be adjusted, thereby adjusting a location of a center of gravity of the club head; the at least one weight member comprises an outer member engaging an outward-facing surface of the at least one ledge, an inner member engaging an inward-facing surface of the at least one ledge, and a fastening bolt comprising a threaded shaft, wherein the threaded shaft extends through a center aperture of the outer member and engages mating threads located in a center aperture of the inner member; the at least one weight member is located entirely external to the interior cavity of the body and the at least one weight member is configured to clamp the at least one ledge at selected locations along the channel, wherein when the at least one weight member is in a selected location, the fastening bolt is tightened until the clamping force between the outer member and the inner member upon the at least one ledge is sufficient to restrain the at least one weight member in place; wherein the face includes a center face location that defines the origin of a coordinate system in which an x-axis is tangential to the face at the center face location and is parallel to a ground plane when the body is in a normal address position, a y-axis extends perpendicular to the x-axis and is also parallel to the ground plane, and a z-axis extends perpendicular to the ground plane, wherein a positive x-axis extends toward the heel end of the body from the origin, a positive y-axis extends rearwardly from the origin toward the interior cavity, and a positive z-axis extends upwardly from the origin toward the crown; wherein adjustment of the at least one weight member provides a maximum x-axis adjustment range of the position of the center of gravity (Max ΔCGx) that is greater than 2 mm and a maximum y-axis adjustment range of the center of gravity (Max ΔCGy) that is less than 3 mm; wherein the weight member has a mass (MWA) and wherein the product of MWA*Max Δx is between 250 g·mm and 4950 g·mm; wherein the product of MWA*Max Δy is between 0 g·mm and 1800 g·mm; and wherein the center of gravity of the club head has a z-axis coordinate (CGz) that is less than 0 mm.
