Title: Golf putter head with adjustable weight-holding cylinder
Inventor: TOMASU JII ANDASON
IPC: A63B53/04
Filed: 1990-08-30
Abstract: PURPOSE: To simplify adjustment of weight by exchanging a weight bolt on the heel side or the toe side of a weight receiving member disposed on the putter head. CONSTITUTION: A golfer can adjust the weight and the sweet spot by combining two optional bolts out of weight bolts 24, 26, 28 and inserting them into both ends of a female screw hole of a weight receiving cylinder 22 so as to obtain a feeling suitable for the state of a putting surface to putt. For example, when a putting surface is 'slow' due to wet lawns, a comparatively long and heavy weight bolt 28 is inserted into the receiving cylinder 22 so as to adjust to the 'slow' putting surface. For another example, when a golfer tends to putt always to the right missing the cup, such a tendency can be reduced by inserting the weight bolt 26 or 28, which is heavier than the weight bolt in the end on the toe side of weight receiving cylinder 22, into the end on the heel side of the weight receiving cylinder 22.

Then the grating section 33x is scanned in the direction perpendicular to the extended direction and coherent rays of light are made incident on another photosensor so that the 0th-order light diffracted by the grating section 33x can be detected by the photosensor. Then two-dimensional positions of the intersection of the grating sections 33x and 33y of the diffraction grating are detected. Since this two-dimensional position detecting method can be performed with the emitting device of the coherent rays of light, its optical system, and one set of photosensors only, the constitution of the detecting device can be made simpler and position detecting accuracy of the device can be improved.
