Abstract:

An iron-type golf club head includes a body having a front face arranged for impact with a golf ball, a heel end, a toe end and a beveled sole. The beveled sole has leading and trailing edges with a ridge located between them. The beveled sole includes a primary surface and a secondary surface, both of which vary in width from the heel end to the toe end. The primary surface is located between the leading edge and the ridge, and the secondary surface is located between the trailing edge and the ridge. The primary surface has a first width dimension adjacent the heel end, a second width dimension measured along a center line located substantially between the heel and toe ends, and a third width dimension adjacent the toe end. The first and third width dimensions of the primary surface are less than the second width dimension of the primary surface. The secondary surface has a first width dimension adjacent the heel end, a second width dimension measured along the center line, and a third width dimension adjacent the toe end.

US Classification:

Abstract:

A golf club is manufactured according to a method in which a radially compliant crush sleeve is interposed between the shaft tip and hosel of the club head. The crush sleeve is fabricated from a strip of metal formed into a substantially cylindrical metallic band with a plurality of radially-extending dimples or corrugations that grip the shaft. The crush sleeve is retained either in an undercut region in the hosel bore, on a mandrel extending from the hosel, or on a pilot shaft at the tip of the golf club shaft. After the interface between the shaft and hosel is coated with an adhesive, the shaft is assembled to the hosel with the crush sleeve squeezed in between. The crush sleeve secures the shaft to the club head with sufficient rigidity to allow the adhesive to set while maintaining the appropriate axial and rotational alignment.
