Golf club head with alignment indicia
A golf club head includes a body and ball alignment indicia that protrudes forwardly of the front surface of the body. A transparent plate covers the ball alignment indicia and has a front face arranged for impacting a golf ball. A flange on the transparent plate is received in a recess in the body thereby forming a mechanical interlock between the transparent plate and the body. The ball alignment indicia has a partial spheroid shape and is located intermediate heel and toe ends of the body.
Latest Karsten Manufacturing Corporation Patents:
The present invention relates to golf clubs and, in particular, to a golf club head with alignment indicia.
It is generally accepted in the golf industry that use of alignment indicia on putter heads assists the golfer in properly aligning the putter head with a golf ball. One example of a prior art putter head with an alignment indicia is disclosed in U.S. Pat. No. 4,688,798 to Pelz. The Pelz patent discloses a putter head with alignment indicia in the form of a row of 2, 3, 4, or 5 golf ball shaped indicators aligned perpendicular to and behind the putter head.
Another example of a prior art putter head with alignment indicia is U.S. Pat. No. 4,659,083 to Szczepanski. The Szczepanski patent discloses a putter head with a group of lines that converge toward the putter head face so that extensions of these lines meet at a point forward of the putter head face.
U.S. Pat. No. 6,905,420 to Tang et al. discloses a putter head similar to that disclosed by the Pelz patent but with only two circular indicia. U.S. Pat. No. 6,988,955 to Stoakes discloses a putter head with a removable cap having alignment indicia including arrowheads, lines, and circles.
SUMMARY OF THE INVENTIONThe present invention provides a golf club head including a body having a heel end, a toe end and a front surface. Ball alignment indicia is attached to the body and extends forwardly of the front surface of the body. A transparent plate is mounted on the body enclosing the ball alignment indicia between the body and the transparent plate. The transparent plate has a front face arranged for impacting a golf ball. The ball alignment indicia is located intermediate the heel and toe ends of the body and has a partial spheroid shape. In the preferred embodiment of the present invention, a flange on the transparent plate is received in a recess in the body thereby forming a mechanical interlock between the transparent plate and the body.
With reference to
Body 12 has an elongated cavity 36 extending rearward from front surface 18, and a partial spheroid shaped cavity 38 extends rearward from the elongated cavity 36. Partial spheroid shaped cavity 38 is closed by ball alignment indicia 40 which has a partial spheroid shape 42 surrounded by a mounting flange 44. The partial spheroid shape 42 of the ball alignment indicia 40 protrudes forwardly of the front surface 18 of the body 12. Ball alignment indicia 40 is attached to body 12 and is located intermediate the heel and toe ends 20, 22 of body 12.
A transparent plate 46 covers ball alignment indicia 40 to form the assembled club head 10 shown in
