Golf club head with removable weight

摘要

A head body h1 includes a recess part 14 for a socket. A socket 10 is attached to the recess part 14 for a socket. A weight body 12 is detachably attached to the socket 10. The weight body 12 can be secured by relative rotation of an angle +θ°. The weight body 12 can be detached by relative rotation of an angle−θ°. The weight body 12 includes an engaging part 32. The socket 10 includes a first hole part 18 and a second hole part 20. The engaging part 32 can take an engaging position EP and a non-engaging position NP at the second hole part 20 by the relative rotations. A sectional shape of the engaging part 32 has N-fold rotation symmetry. N is an integer of 1 or greater and 3 or less.

1. A golf club head comprising: a head body including a recess portion for a socket; a socket attached to the recess portion for a socket; and a weight body detachably attached to the socket, wherein
the weight body can be secured by relative rotation of an angle +θ° to the socket; the secured weight body can be detached by relative rotation of an angle −θ° to the socket; the weight body includes an engaging portion for engaging the socket, wherein a distance between a central point and a point farthest from the central point in an outline of a section of the engaging portion is defined as R1, a distance between a central point and a point nearest to the central point in an outline of a section of the engaging portion is defined as R2, and the ratio R1:R2 ranges from 1.30 through 1.70 inclusive; the socket includes a first hole and a second hole positioned on a deeper side than the first hole, wherein said second hole includes a reverse rotation suppressing portion which protrudes inwardly, configured such that engaging portion distance R1 and a maximum height of the reverse rotation suppressing portion R3 have a ratio R3:R1 equal to or greater than 0.19, and said second hole includes an excess rotation suppressing portion which protrudes inwardly, configured such that engaging portion distance R1 and a maximum height of the excess rotation suppressing portion R4 have a ratio R4:R1 equal to or greater than 0.19; the engaging portion is movable into an engaging position EP and a non-engaging position NP at the second hole; assuming that rotation of the weight body is rotation about an axis line Z, the engaging portion has a sectional shape with N-fold rotation symmetry with the axis line Z as a rotation axis, wherein N-fold rotation symmetry signifies that a cross-sectional shape after being rotated by 360/N degrees about a rotation axis coincides with the cross-sectional shape before such rotation; and the maximum value of N is 1, 2, or 3.
