Putter head

Abstract

The putter head has a front face with a heel and toe edge extending from the front face, giving the head an overall triangular configuration. Both the heel and toe surfaces have cavities extending from the outer surface toward a central wall. The central wall is perpendicular to the face of the putter to provide visual indication that the face is square to the intended putting line. Two semicircular cavities extend from the top surface of the putter and are separated by the central wall. Medallions on the upper surface of the putter sole are aligned with the semicircular cavities. If the golfer's eyes are not directly over the putter with the sole at 0 degree lie angles, the central wall and horizontal cavities will obscure part of the medallion. If the golfer's hand position is forward, de-lofting the putter surface or laid back adding loft to the base, the forward or rearward edges of the semicircular holes will obscure the edges of the medallions. In this manner, the semicircular holes and medallions give visual indication to the golfer that the placement of the putter relative to the green, the golfer's hand position relative to the club and the golfer's head position are correct.

DETAILED DESCRIPTION OF THE INVENTION

The top view of the putter head is clearly seen in FIG. 1. The putter has a flat, planar front face 12 with heel 14 and toe 16 extending backwardly from the front face and joining one another at an arcuate point. Both the heel and toe taper inwardly to the top surface 18. A first horizontal cavity extends in the heel 14 into the putter head. Likewise, a second horizontal cavity 24 extends inwardly through the toe 16. The first horizontal cavity and second horizontal cavity are coaxial and separated from one another by a central wall 30. Extending downwardly from the top surface 18 on either side of the central wall 30 is a first semicircular cavity 26 and second semicircular cavity 28. These cavities communicate with the first and second horizontal cavities, respectively.

Behind the semicircular cavities is indicia to further facilitate the alignment of the putter to the putting line. The indicia includes a line that is collinear with the central wall 30. This extension of the visual cue given by the central wall makes it easier for the golfer to align the putter. While the indicia may take many forms, one embodiment is a pair of white semicircles 34,36 which are slightly smaller than the cavities. The semicircles are oriented to form a circle with the space between the semicircles forming a line that is collinear with the central wall 30.

Printed directly below the vertical semicircular cavities is visual indication of proper alignment of the putter. The visual indication is a medallion 32 having a first appearance when the putter is correctly aligned and a different appearance when the putter is misaligned. This can be done by having the edges of the medallion in registry with the edges of the semicircular cavities. A semicircle having a white outline centered under the semicircular opening is a preferred design and is illustrated in FIG. 1.

If viewed at the wrong angle, parts of the medallion are obscured. If the golfer's eyes are not directly over the putter with the sole at 0E lie angles, the central wall and horizontal cavities will obscure part of the medallion. If the golfer's hand position is forward, de-lofting the putter surface or laid back adding loft to the base, the forward or rearward edges of the semicircular holes will obscure the edges of the medallions. Any design element changing the appearance of the medallion when viewed during misalignment of the putter can be used. This can be a changing color, with only one color visible when correctly aligned, but a second color becoming visible during misalignment.

FIG. 2 is a cross-sectional view of the putter head through the central wall 30. The sole 20 of the putter head can be seen, with the top surface for the medallion. FIG. 3 shows a cross-sectional view through the first horizontal cavity 22. FIG. 4 is a side view of the putter head showing the first horizontal cavity 22. The opposite side view is mirror image showing the second horizontal cavity 24.

The front face 12 is seen in FIG. 5. The front face 12 may be formed with the recess to accommodate a resin insert, forming the striking surface. A visual indication of the center of the front face, such as a circle or any other suitable design, may be used to enhance the alignment of the putter face to the golf ball.

While the invention has been described with reference to a preferred embodiment, variations and modifications would be apparent to one of ordinary skill in the art. The invention encompasses such variations and modifications. For instance, the vertical cavities do not have to be semicircular nor do they have to communicate with a horizontal cavity. A single vertical cavity may be used without a central wall.
