Golf club gauge

摘要

A golf club gauge includes a frame, a clamping means, and a hand-held electronic level which can be zeroed to establish a reference plane. The level is positioned relative to a reference surface of the frame and relative to a surface to be measured, and using information obtained in these two positions, the level is used to square a head in the frame and also to measure the head's loft, lie, and face angles. An attachment is provided for the level which improves accuracy when it is used on heads with arcuate faces.

1. An apparatus used to determine loft angle and lie angle of a golf club head, the golf club head having a sole, an arcuate face, and a hosel with an axis, the apparatus comprising:
a frame having a first planar surface which is a ground plane for the head's sole; a clamping means attached to the frame for holding the head in positions relative to the frame with the hosel's axis in a shaft plane which is substantially perpendicular to the ground plane; a detachable level having a first planar side with a first edge and a second edge parallel with the first, a second planar side with a first edge and a second edge parallel with the first, and a known angular relationship between the level's first planar side and its second planar side; and an attachment which can be placed on the first planar side of the level, the attachment having projections which include a first projection and a second projection which project substantially equal distances from the first planar side of the level when the attachment is placed thereon; wherein a first level reading is obtained with a side of the level placed on the frame's first planar surface and a second level reading is obtained with a side of the level placed on the clamping means, whereby information about the head's lie angle is obtained by comparing the first level reading to the second; and wherein a third level reading is obtained with a side of the level placed on the frame's first planar surface and, with the first side of the level adapted for use on the arcuate face by having the attachment positioned thereon, a fourth level reading is obtained with the attachment's first and second projections touching the arcuate face at two points and thereby positioning the level's first planar side substantially parallel with a line through the two points on the face, whereby information about the head's loft angle is obtained by comparing the third level reading to the fourth.
