Brief Patent Description - Full Patent Description - Patent Application Claims
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 trajectory of the golf ball. The invention also relates to a golf club head having a spirit level that indicates the center of the golf club face, and sight-alignment indicia formed on the top surface of the golf club head as an integral part thereof to improve one's swing and to enable a person to become more proficient at the game of golf. The spirit level may form part of the sight-alignment indicia [0004] 2. Description of the Prior Art Heretofore, spirit levels or sight-alignment indicia attachments have been incorporated in a golf club, and particularly in the head of a putter, in order to indicate the levelness of the golf club head in the direction of the face of the club to indicate the inclination of the golf green when the putter is placed on the golf green. The spirit level serves to indicate slope relative to geophysical flat. 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. [0005] U.S. Pat. No. 2,919,922 to Skelly for a GOLF CLUB shows a golf putter incorporating a liquid level indicator in the putter head. The usage of such liquid level is taught as permitting the golf club head to be held in a horizontally level position during a putting stroke. [0006] U.S. Pat. No. 2,923,552 to Sundberg for a GULF PUTTING COORDINATOR DEVICE shows a spirit level much in the manner of Skelly. The spirit level is preferably in the shape of a shallow U-shape tube, and is magnetically affixed to the rear side of a golf club head, particularly a putter head, for indicating horizontal levelness [0007] U.S. Pat. No. 2,976,046 to McCullough, Jr. for a GOLF CLUB is also directed to a permanent spirit level formed integrally with a head of a golf club or a putter. The base of the club head is flat in order to permit the spirit level to give an accurate indication of inclination when the club head is positioned along the line of a perspective putting stroke. [0008] U.S. Pat. No. 2,995,375 to Bukovey for a GOLF CLUB likewise shows a golf putter head incorporating a spirit level. By observation of the level indications the slope of the green in several directions may be determined. [0009] U.S. Pat. No. 3,429,576 to Ikeda for a GOLF CLUB HAVING LEVEL INDICATING MEANS AND WEIGHT MEANS shows a putter head having both a level and a dead weight. The level indicates club head orientation in a horizontal direction. [0010] U.S. Pat. No. 3,909,004 to Vella for a PUTTER HAVING CIRCULAR LEVEL shows and describes a putter with a two dimensional spirit level. By observation of the level, the orientation of the shaft relative both to horizontal, and to vertical, may be observed. [0011] U.S. Pat. No. 4,082,286 to La Breche for a DIRECTION AND SLOPE INDICATING PUTTER HEAD shows a putter head with a spirit level and a scale for assistance in putting. [0012] U.S. Pat. No. 5,160,142 to Marshall for a GULF PUTTING TRAINING DEVICE shows a gulf club having both a spirit level and a number of angularly disposed pockets into which a small contained ball will role during the putting stroke. [0013] U.S. Pat. No. 4,824,114 to Catalano for an GULF PUTTER WITH SLOPE INDICATING MEANS THEREIN discloses a golf club incorporating a particular level which, when a club is placed on the green prior to a putting stroke, operates as a pendulum, or plumb bob, in order to determine, and to indicate, the angle of the putting green from horizontal. [0014] U.S. Pat. No. 5,209,470 for a GOLF GREEN SLOPE READING LEVEL shows a golf club head incorporating a spirit level which may be viewed by retracting a sliding window. The spirit level is positionable, with the help of indicia marked on the club head, in order to assess the slope of the green. [0015] U.S. Patent No. 5,707,299 for a LEVEL INDICATING GOLF PUTTER shows a golf club putter having a spirit level indicator positioned transversely to the direction of ball travel and placed on two protuberances extending rearward from the golf club head. [0016] The preferred embodiment of the present invention will be seen to possess a distinct form which supports its functional purposes. There is no suggestion in the prior art of the use of such a form in combination with a spirit level, nor for the purposes to which such form is put by Applicant. SUMMARY OF THE INVENTION [0017] One of the objects of this invention is to provide a new and improved golf club with a level indicating device therein. [0018] Another object of this invention is to provide a new and improved golf club with a head with a level indicating device therein which indicates the levelness of the golf club head in the direction of the golf ball travel, and transverse to the face of the golf club head. [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. [0020] A further object of this invention is to provide a new and improved golf club head with a level indicating device that also indicates the center of the golf cub face for striking the ball. [0021] Another object of this invention is to provide a new and improved golf club head with a level indicating device and sight alignment indicators. [0022] Other objects of this invention will become apparent from time to time throughout the specification and claims hereinafter related.
