Golf club head including level and alignment indicators
First Claim
Patent Images
1. A golf club head comprising:
- a body member having and defining an elongate flat planar face for contacting a golf ball, said planar face having a midpoint defining the proper position on the planar face for contacting the golf ball a sole that lies in a curved surface everywhere perpendicular to the plane of the face an upper curved surface that is everywhere substantially perpendicular to the plane of the face an outer free end disposed opposite an inner end configured to receive a golf club shaft a bore extending inwardly from the midpoint of the flat planar surface and disposed along an imaginary axis perpendicular to the outer free end, on the upper curved surface, said bore having an aperture therein an elongated spirit level positioned in said bore and aperture to be viewed by the golfer, said spirit level having an internal level-indicating means and an external level-indicating means wherein at such times as the golf club head is aligned properly with the golf ball being at the midpoint of the planar face and the golf club head is angled correctly, the spirit level indicates that the golf club head is in the proper attitude for striking the golf ball.

Abstract
A spirit level is added to the club head of a golf club, such as a golf club driver, and observation of the level indicator bubble in the spirit level tells the golfer the level alignment of the golf club head, in the direction of the intended golf ball flight, when the golf club is in position to drive the golf ball. When the golf club head is level in this direction, the golf club face is in the proper position for striking the golf ball. The spirit level is constructed to withstand the speed of the golf club head as it is swung towards the ball, as well as the impact in striking the ball. The spirit level also functions as a golf club sight alignment indicator as pointing to and being aligned with the proper position at the center of the golf club face that should come in contact with the golf ball. The alignment indication aspect of the spirit level may also be enhanced by alignment indication markings on the top of golf club head for indicating the proper position for alignment of the golf club.

9. A golf club head comprising:
-
a body member having and defining an elongate flat planar face for contacting a golf ball, said planar face having a midpoint defining the proper position on the planar face for contacting the golf ball an upper curved surface that is everywhere substantially perpendicular to the plane of the face a bore extending inwardly from the midpoint of the flat planar surface and disposed along an imaginary axis perpendicular to the outer free end, on the upper curved surface, said bore having an aperture therein an elongated spirit level positioned in said bore and aperture to be viewed by the golfer, said spirit level having an internal level-indicating means and an external level-indicating means;
said spirit level comprising an elongated plastic tube and having an arcuate upper surface, andalignment indicator markings on said upper curved surface for indicating the alignment of the midpoint of said flat planar face with a golf ball, wherein at such times as the golf club head is aligned properly with the golf ball being at the midpoint of the planar face and the golf club head is angled correctly, the spirit level indicates that the golf club head is in the proper attitude for striking the golf ball. - View Dependent Claims (10, 11, 12, 13, 14, 15)
