摘要:
A golf club head and a set of golf clubs that are more forgiving are disclosed herein. The golf club head has an open cavity with an extended bottom wall in order to lower the center of gravity of the club head and to increase the moment of inertia of the club head. The set of golf clubs preferably consists of a driver, a plurality of fairway woods and a plurality of irons, with each of the club heads having a lower center of gravity and increased moment of inertia. Each club head preferably has a moment of inertia of at least 2600 grams centimeter squared.

A golf club fitting device (20) is disclosed herein. The fitting device (20) includes a club head (22) with an internal hosel (38) that has a bore (39) that extends from a crown opening (52) to a sole opening (62). A removable insert (51) is disposed within the internal hosel (38), and a shaft (40) is disposed within a chamber (77) of the removable insert (51). The removable insert (51) has an annular indentation (73) for engagement with a locking member (57), and a plurality of recesses (83) for engagement with a rotation detent (59). The chamber (77) is disposed at a predetermined angle within the removable insert (51) to define a face angle of the golf club fitting device (20). The removable insert (51) is capable of rotation within the bore (39) of the internal hosel (38) to adjust the face angle of the fitting device (20). Further, the removable insert (51) and shaft (40) are easily removed from the club head (22) and substituted therefor.
摘要:
The present invention is a golf club (30) having a club head main body (34) with a hollow interior (49), a support layer 41 defining a depth of a recess (38), a polymer insert (40) in the recess (38), an isolation layer (52) and a weight body (50). The polymer insert (40) is composed of a thermosetting polyurethane material having a Shore D hardness in the range of 42 to 55, and a Bayshore rebound in the range of 51 to 60. The preferred thermosetting polyurethane material is formed from a p-phenylene diisocyanate prepolymer and a curing agent. The golf club (30) is preferably a putter, however, it may be a wood or an iron. The particular thermosetting polyurethane provides a soft striking face for feel and a good rebound for distance. The weight body (50) is preferably composed of a tungsten alloy, and the isolation layer (52) is preferably composed of a thermoplastic polyurethane.
摘要:
A golf club head comprising toe and heel portions, a front wall defining a ball-striking face, and top and bottom walls, the bottom wall characterized as having a medial ridge, and as forming two shallow recesses, one recess between the ridge and the heel portion, and the other recess between the ridge and the toe portion, the recesses everywhere spaced rearwardly from the front wall, the one recess having an arcuate peripheral edge generally convex toward the heel portion, and the other recess having an arcuate peripheral edge generally convex toward the toe portion.
摘要:
A golf club head having a body defining a heel, toe, top wall, sole defining a bottom wall, and a front wall defining an upwardly and rearwardly inclined front face, and comprising the body defining a forwardly extending main recess located rearwardly of the front wall; and the body also defining an undercut recess located directly rearwardly of the front wall and extending outwardly from the main recess toward one or more of the following: i) the top wall ii) the bottom wall iii) the toe iv) the heel; and structure on said front wall and located forwardly of the main recess for attenuating audible vibration created when a golf ball is struck by the front face. The front wall has a rear side, and the referenced structure on the front wall is attached to the front wall rear side and is everywhere spaced from the undercut recess, the undercut recess openly exposed to the main recess.
