Golf putter head with interchangeable rebound control insert
First Claim
1. A golf putter head comprising;
- a. a head adapted to be attached to a shaft, said head including a body having a front face with an intended golf ball impact region, said front face of said body having formed therein a recess, andb. at least one rebound control insert releasably adapted to fit in said recess of said body, said insert having at least a front portion thereof made of a resilient polymer and providing a composite rebound factor having a predetermined value selected from a first plurality of values, said composite rebound factor being determined by the resiliency or intrinsic rebound factor of the particular material of which said insert is made and by the thickness of said insert in combination with the characteristics of said body, said composite rebound factor values being related by a predetermined, repeatable relationship to the roll distance of a ball impacted by said putter, andc. releasable fastening means for fastening said insert to said body.

Abstract
A golf putter providing improved control of distance and direction of a golf ball impacted by the putter includes a resilient insert having a controlled rebound factor fitted into a wedge-shaped recess provided in the face of the putter head. The insert includes a front rebound control pad made of a resilient polymer material, and a rear backing plate releasably fastenable to the putter head. Intrinsic resiliency, thickness and hardness of the pad are chosen to yield in combination with the putter head body an overall, composite ball-impacting rebound factor that may be varied over a relatively wide range of rebound factors, which determine in a substantially linear way the roll distance of a ball impacted by the putter. The insert may be readily interchanged by a golfer with other inserts which provide higher or lower rebound factors, which may be chosen on days in which greens were slower or faster, respectively. Optionally, the hardness of an insert may be varied somewhat independently from rebound factor, thus achieving a desired ball-impacting feel as well as selected rebound factor.

8. A golf putter head comprising;
-
a. a laterally elongated body having upper and lower wall surfaces and a generally flat front face with an intended region for impacting a golf ball, said face having formed therein a generally trapezoidally-shaped recess which extends through both said upper and lower wall surfaces of said body, b. at least one rebound control insert having a plan view shape complementary to that of said recess, said insert being adapted to fit conformally within said recess and having at least a front portion thereof made of a resilient polymer, said insert providing a composite rebound factor, for a ball impacted by said head, of a predetermined value selected from a first plurality of values, said composite rebound factor being determined by the resiliency or intrinsic rebound factor of the particular material of which said insert is made and by the thickness of said insert in combination with the characteristics of said body, said composite rebound factor values being related by a predetermined, repeatable relationship to the roll distance of a ball impacted by said putter, and c. releasable fastening means for fastening said insert to said body. - View Dependent Claims (9, 10, 11, 12, 13, 14)
