Abstract

In construction of an iron-type golf club head provided with a face side shooting board, the shooting board is fitted into a recess formed in the face of a main body and an elastic intermediate is interposed between the shooting board and the recess. At shooting a ball, the shooting hoard is allowed to perform elastic displacement within the recess opposite to the direction of back-spin impartation to the ball, thereby mitigating ill influence of excessive back-spin and assuring good control on ball rolling on the field, in particular on a putting green.

Claims

1. A golf club head, comprising:

a main body having a face, the face including a recess having an end wall extending from a bottom to a top side, the recess having a top edge,

a shooting board having a top edge and an exposed surface for striking a ball and imparting a back-spin to said ball, the shooting board being fitted into said recess with said exposed surface substantially flush with said face on said main body and with at least said top edge of said shooting board spaced from said top edge of said recess, and

an elastic intermediate interposed between said top edge of said recess and said top edge of said shooting board, said elastic intermediate having sufficient elasticity so that when the shooting board strikes a ball to impart back-spin thereto, the shooting board may move toward the top edge of the recess to impart a force to the ball in a direction opposite to said back-spin.

2. A golf club head as claimed in claim 1 in which said main body is an iron-type main body.

3. A golf club head as claimed in claim 1 in which a plane containing said end wall of said recess extends substantially in parallel to a plane containing said face.

4. A golf club head as claimed in claim 1 in which said end wall of said recess is inclined with respect to said face so that the depth of said recess Increases gradually from said bottom to said top side of said face.
