Abstract:
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 the heel, the face being interposed the toe and the heel;a sole interposed the heel and the toe and disposed below the face;a top-line interposed the heel and the toe and superposed the sole and the face;a back defined by a second plane which is inclined relative to the first plane defining the face, the back being opposite the face and having a single open cavity extending toward the face and covering a majority of the back, the cavity having a first larger portion adjacent the toe and a second smaller portion adjacent the heel;a peripheral belt surrounding the cavity of the 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 the toe, heel, sole and top-line perimeter portions, wherein a majority of the weight of the club head is disposed within the peripheral belt; anda single bridge member superposed a portion of the cavity, spaced away from said rear surface of said face, the bridge member comprising a first end and a second end attached to the belt in combinations, respectively, selected from a group consisting of the top-line perimeter portion and the toe perimeter portion, the top-line perimeter portion and the heel perimeter portion, the top-line perimeter portion and a junction perimeter portion, the sole perimeter portion and the heel perimeter portion, the sole perimeter portion and a junction perimeter portion, the heel perimeter portion and a junction perimeter portion, the toe perimeter portion and a junction perimeter portion, and a first junction perimeter portion and a second junction perimeter portion so as to place the center of mass of the bridge member in a predetermined location different from the location of the center of mass of the club head absent the bridge member;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 center of mass of the bridge member relative to the center of mass of the club head absent the bridge member.
