BACKGROUND OF THE INVENTION
The present invention relates generally to golf equipment and, in particular, to a golf club head with an alignment guide.
Proper alignment of golf club heads is essential for their effective use. Because golf club heads are often constructed of metal, light reflecting off these metal golf club heads may produce glare and shadows thus making sighting and aligning of the club heads difficult and inaccurate. Also, different player preferences and course conditions may require adjustment in the weight of the club head for optimum performance.
SUMMARY OF THE INVENTION
The present invention provides a golf club head including a body having a face member and a flange member extending rearwardly from the face member. The face member includes a front surface arranged for impacting a golf ball, and the flange member has an upper surface with a cavity formed therein. An alignment guide or insert disposed in the cavity in the flange member has a plurality of substantially parallel grooves separated by a ridge. The insert is oriented in the cavity so that the grooves and the ridge are perpendicular to the face member front surface.

DESCRIPTION OF THE INVENTION
With reference to FIG. 1, a golf putter head 10 is preferably made of metal such as stainless steel, titanium, titanium alloys, carbon steel, bronze, and the like. In accordance with one embodiment of the present invention, the putter club head 10 includes a body 11 having a face member 12 and a flange member 14 extending rearwardly from the face member 12. The face member 12 has a front surface arranged for impacting a golf ball. The flange member 14 has an upper surface with a cavity 16 formed therein. As illustrated in FIG. 2, the cavity 16 has a generally semicircular shape with its diameter approximating that of a golf ball.
As illustrated in FIG. 3, the alignment guide or insert 18 has substantially parallel grooves 20 and substantially parallel ridges 22 on its top surface. The alignment guide or insert 18 has a generally semicircular configuration that matches the generally semicircular shape of the cavity 16. The insert 18 is secured in the cavity 16 in a predetermined orientation so that the grooves 20 and ridges 22 are perpendicular to the front surface of the face member 12. The insert 18 is preferably made of a color that contrasts with the putter head 10.
FIG. 4 illustrates the three-dimensional aspect of the top surface of the insert 18. The parallel grooves 20 are separated by the parallel ridges 22. The grooves 20 preferably have a concave profile while the ridges 22 have a convex profile. The grooves 20 reflect ambient light differently from the ridges 22 thus ensuring easily recognizable contrast zones between the grooves 20 and the ridges 22. These contrast zones define parallel lines perpendicular to the front surface of the face member 12 thereby providing accurate alignment references which are highly visible to a golfer in various lighting conditions.
The insert 18 may be permanently mounted in the cavity 16 by using an adhesive such as epoxy. Alternatively, the insert 18 may be removably mounted in the cavity 16 by using threaded fasteners.
The present invention may also provide a plurality of inserts 18 of different weights and different visual characteristics. Inserts of different weights may be provided by varying the thickness of the inserts or the density of the material used to form the inserts. As illustrated in FIG. 2, since the cavity 16 is located near the center of gravity of the putter head 10, the putter head center of gravity will not change significantly when selecting and installing any of the plurality of inserts.
Although the preferred embodiment of the insert 18 is shown in the putter head 10, other embodiments of inserts could be made for use with wood heads and iron heads.
