CORRELATED SET OF GOLF CLUB HEADS HAVING VIBRATION DAMPING PLAQUES OF UNIFORM SIZE AND SHAPE, AND GOLF CLUB HEAD WITH IMPROVED INSET/OFFSET HOSEL

摘要

A correlated set of iron-type golf club heads,wherein each head in the set employs the same sizedvibration damping plaque. Each club head includes asubstantially planar blade element having a frontstriking face for impacting a golf ball, and a rearsurface opposite the front striking face. A perimeterweighting element is formed integrally with at least aportion of the outer perimeter of the rear surface andextends substantially rearwardly from the rear surface.The remainder of the rear surface not covered by theperimeter weighting element defines the bottom of an opencavity which is substantially surrounded by an innerperipheral surface of the perimeters weighting element.The area and shape of the remainder of the rear surfacethat defines the bottom of the open cavity aresubstantially identical in each club head of thecorrelated set, thus making it possible to use the samesized and shaped vibration damping plaque in each clubhead. The invention additionally includes an iron-typegolf club head, including a front striking face, a rearsurface opposite the front striking face, a toe portion,a heel portion opposite the toe portion, and a top railsurface portion projecting rearwardly from an upperperiphery of the front striking face and extendingbetween the toe and heel portions. The hosel is offsetand inset, and extends generally upwardly and forwardlyonly from the heel end portion of the top rail, such thatthe hosel does not occupy any portion of the frontstriking face and does not impede contact between thefront striking face and a golf ball.
