First Claim
Patent Images
1. An iron-type golf club head having a solid metal body comprising:
- a face defined by a substantially flat first plane and including a golf-ball-striking surface with a center portion, said face having an opposing rear surface;
a heel having an upwardly extending hosel for receiving one end of an elongated shaft;
a toe opposite and taller in height than said heel, said face being interposed said toe and said heel;
a sole interposed said heel and said toe and disposed below said face;
a top-line interposed said heel and said toe and superposed said sole and said face;
a back defined by a second plane which is inclined relative to the first plane defining said face, said back being opposite said face and having a single open stepped cavity extending toward said face and covering a majority of said back, said cavity having a first larger portion adjacent said toe and a second smaller portion adjacent said heel;
a peripheral belt surrounding the cavity of said back and including a toe perimeter portion, a heel perimeter portion, a sole perimeter portion, a top-line perimeter portion and junction perimeter portions interposed adjacent ones of said toe, heel, sole and top-line perimeter portions, wherein a majority of the weight of the club head is disposed within said peripheral belt; and
a single bridge member superposed a portion of said cavity, spaced away from said rear surface of said face and disposed along the second plane defining said back, said bridge member comprising a first end attached to one of said top-line, heel, toe, sole and junction perimeter portions and a second end attached to one of said top-line, heel, toe, sole and junction perimeter portions;
whereby the trajectory of a ball struck by the center of the golf-ball-striking surface of the face is influenced by the location of the bridge member.

Abstract
The present invention provides an iron-type golf club head having a bridge member across a cavity on its rear surface, which member influences the trajectory of a golf ball struck by the club head. By altering the bridge member orientation across the cavity on the rear surface, the club head can be made to propel a ball in various directions. Thus, the trajectory of golf balls struck by the club head can be high, low, rightward, leftward, or combinations thereof.
