Golf club head including level and alignment indicators

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.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to new and useful improvements in golf clubs, and particularly golf club heads, and more particularly the head of a golf club driver. [0003] The present invention further concerns golf club heads incorporating a spirit level so that when the golfer addresses the golf ball with the golf club prior to driving or hitting the ball, with its spirit level in alignment with the direction of golf ball travel towards the hole, then the spirit level will indicate the proper levelness of the golf club with respect to the face of the golf club. The spirit level indicates the levelness of the golf club head in a direction transverse to the direction of the plane of the golf club face. When the golf club head is properly level in this manner, the face of the golf club head is in the proper orientation to the ball such that the angle of inclination of the face of golf club head will define the flight ...

AI Technical Summary

Benefits of technology

[0019] Another object of the invention is to provide a new and improved golf club head with a level indicating device that can withstand the speed of the golf club head and the impact when striking the golf ball.

[0023] The foregoing objects and other objects of the invention are accomplished by a golf club head, particularly a driver head, having a substantially vertically oriented striking surface for striking a golf ball on swinging movement of the golf club, and a second upper surface, defining the top of the golf club head, at substantially a right angle to the striking first surface. An elongate spirit level is supported in the second upper surface for indicating the levelness of the club head in a “front-to-back” orientation. That is, the elongated spirit level is positioned so that one end of the level is directed toward the face of the golf club head and the opposite end is directed toward the back of the club head, so that the spirit level itself points in the direction of intended travel of the golf ball. Being oriented in this manner, the spirit level indicates levelness of the club head, not in the horizontal direction parallel to the club face as in the prior art putter applications, but in a horizontal orientation transverse to the club head, that is from front to back or from the club face to the back of the golf club head. When the golf club head is level is in this orientation, the face of the golf club is in the proper position so that the pre-set angle of the club face will define the intended flight trajectory of the ball, resulting in more consistent flight of the ball with the particular club.

Problems solved by technology

These prior art devices are essentially limited to indicate when the golf club is horizontally level along an axis perpendicular to the direction of ball travel.
