Abstract

A flange member is joined to a rear surface of a face member, which defines a sole, and extends backward. A sole member depends from the flange member and defines a further sole.

Claims

1. A head of a golf club comprising a face member with a substantially flat face for driving a ball, a sole defined by a lower portion of said face member, at least one flange member joined to a rear surface of the face member, at least a part of a joint surface between said flange member and said rear surface of said face member being within a range of (diameter of ball)×

1/2--((depth of ball sunken below turf surface)+(height of sole of face member above turf surface)) measured vertic from a lowermost end of the head, said flange member extending substantially in a direction opposite to a direction of said ball to be struck such that at least a part of a vertical section of said flange member with respect to the direction of said ball to be struck is at most the same height with said surface of the joint, and a sole member depending from said flange member to define a further sole.

2. A head as defined in claim 1 wherein said at least a part of the joint surface between said flange member and said rear surface of said face member is at a height of 15 mm±

3 mm measured vertically from said lowermost end of said head.

3. A head as defined in claim 1 wherein said further sole is joined at its end portions outside of the distance of the flange member to the back surface of the face member for reinforcement.

4. A head as defined in claim 2 wherein said further sole is joined at its end portions outside of the distance of the flange member to the back surface of the face member for reinforcement.
