Putter

摘要

When hitting a ball to a target with a putter, the ball often travels to a point which is deviated to the right from the target. When a golfer looks at the target just after taking his address, he turns his head to a target about a rotation axis which extends through the back of his head. When this rotation axis is not horizontal and an angle defined by the rotation axis and his sighting line to a putter head is not 90°, he has an optical illusion which tricks him into believing that he has to correct his address position. The putter of the present invention is provided with a thin-plate pendulum thereby allowing him to turn his head about the rotation axis while keeping the angle defined by the rotation axis and his sighting line at 90°.

主权项

1. A putter, comprising a putter head, the putter head, comprising:
a sole surface; a hitting surface extending upwardly away from the sole surface; and a thin-plate pendulum on an opposite side of the hitting surface; wherein the thin-plate pendulum has a thin-plate pendulum body having an upper end surface, perpendicular to or generally perpendicular to the hitting surface, and a rotation axis member on the opposite side of the hitting surface, at a position corresponding to a center of the hitting surface, the rotation axis member extending generally perpendicular to the hitting surface and generally parallel to the sole surface, and supporting an upper portion of the thin-plate pendulum body, wherein the thin-plate pendulum body is swingable on an axis of the rotation axis member and supported by the rotation axis member so as to be always oriented vertically, the thin-plate pendulum body being perpendicular to the sole surface and extending upwardly in an upward direction away from the sole surface when the putter head is placed with the sole surface horizontal.
