| 20080200278 | Golf Club Head Construction and Method for Improved Target Alignment - A golf club head is configured for an orientation of the face such that an intended target line is directed along an actual target line for a non-zero lofted club face and a preselected non-zero sole angle selected from sole angles within heel up and toe up orientations of the golf club head. | 08-21-2008 |
| 20080248893 | WEIGHT-BALANCED GOLF PUTTER HEAD - A golf putter head is generally triangular, when viewed from the top, with a flat, front face and a trailing, central tail. When viewed from the side, the head has a generally straight front face and a flat or slightly curved or rounded bottom surface. The shaft for the grip is anchored to the head at a generally central position on the top of the head, with the axis of the shaft from the ball contact point on the face of the putter head being about one-half the diameter of a legal U.S. golf ball. The head is formed and/or weighted so that the shaft is on the horizontal center of gravity of the putter head, and the vertical center of gravity is about midway between the top and bottom surfaces of the head. | 10-09-2008 |
| 20090054174 | Gravity action putter and methods of use - The current invention is a golf putter designed to be held by only one hand in order to achieve the ability to produce a pure pendulum motion. The pure pendulum motion has many advantages and solves problems encountered with the conventional two hand putting method. The shaft diameter is large enough to be gripped comfortably by one hand, anywhere along the shaft, and held against the arm, so that the arm and putter move in unison as a pendulum whose pivot point is the joint of the golfer's upper arm and shoulder. The golfer can move the putter in a coplanar motion similarly to a pure pendulum. The striking face of the putter may be set and maintained perpendicular to the target line, thereby solving the variable face angle problem attendant putting with two arms. Other putting errors are eliminated. The putter also works with two hands. | 02-26-2009 |
| 20090069110 | Golf putter - A golf putter providing a center mount of the hosel to the club head and a shaft engagement to the hosel at the heel end of the club head. The center mount provides the sole engagement of the hosel to the head as a gap is formed by a pathway formed through the body of the head which is larger than the circumference of the hosel in its communication therethrough. The centered engagement provides better touch to the user and feedback on striking a ball while concurrently removing the shaft from the user's line of sight to the ball and club face and reduces the twist or torque at impact with a golf ball, thereby increasing the moment of inertia. | 03-12-2009 |
| 20110065525 | GOLF PUTTERS HAVING CENTRALLY ALIGNED HOSELS - Golf putters having centrally aligned hosels are disclosed herein. According to an embodiment of the presently disclosed subject matter, a golf putter includes a head defining a surface for striking a golf ball. The putter also includes an elongated shaft having an axis spaced forwardly a predetermined distance from a plane containing the striking surface. Further, the putter includes a hosel connected to an end of the shaft. The hosel is connected to a portion of the head substantially aligned with a center of the golf ball when the head lies in striking position with respect to the golf ball. | 03-17-2011 |
| 20120077615 | Golf Putter - A golf putter providing a mount of the hosel to the club head and a shaft engagement to the hosel adjacent to the heel end of the club head. The mount provides the sole engagement of the hosel to the head as a gap is formed by a pathway formed through the body of the head which is larger than the circumference of the hosel in its communication therethrough. The engagement provides better touch to the user and feedback on striking a ball while concurrently removing the shaft from the user's line of sight to the ball and club face and reduces the twist or torque at impact with a golf ball, thereby increasing the moment of inertia. An arc-shaped section of said hosel is employable to further balance the club on the hosel and with the shaft. | 03-29-2012 |
| 20120083356 | METHOD OF PUTTING AND A PUTTER - A method of putting a golf ball located on a putting green into a hole includes grasping a putter with at least one hand of a golfer and locating the putter at a first position such that the putter head is positioned proximate the golf ball and is at least four feet from the golfer. Furthermore, the method includes translating the putter head away from the golf ball to locate the putter at a second position, and orienting the shoulders of the golfer to be substantially perpendicular to the putter shaft in the second position. Additionally, the method includes translating the putter head towards the golf ball while the shoulders of the golfer face the hole, and instantaneously striking the golf ball with the putter head to cause the golf ball to develop a top spin and translate in a direction along a line of the putt towards the hole. | 04-05-2012 |
| 20130237341 | PUTTING TRAINING DEVICE - A golf club device for improving one's golf abilities is disclosed. The device includes a head, and a shaft where the head is rotatably connected to at least an upper portion of the shaft. Rotation is achieved with an angular rotation mechanism. The angular rotation mechanism may include a variable resistance feature. The angular rotation mechanism may be positioned in or on the head, or it may be positioned in the shaft. One or more visual alignment indicators may also be employed. | 09-12-2013 |
| 20130288817 | GOLF PUTTER - An improved putter includes a putter head having a face, a toe, and a heel. The putter also includes an elongated shaft that has a longitudinal axis. The face of the putter and back portion of the putter is convexly curved. | 10-31-2013 |
| 20140024473 | Golf Club with Adjustable Shaft - A golf club adjustable for use by right handed or left handed golfers is provided comprising a club head defining a club head cavity and a ball striking face. The golf club further includes a shaft and a club head connecting mechanism disposed within or proximate the club head cavity and connectable to the club head and to the shaft, the club head mechanism being adjustable to facilitate translation of the vertical orientation of the shaft relative to the club head, in a plane parallel to a striking surface, while the shaft remains connected to the club head, and angle of the striking surface with respect to the ground remains unchanged. | 01-23-2014 |
| 20140057735 | SCIENTIFIC GOLF AND EQUIPMENT - A scientific method of golf employs a pendulous or near pendulous swing to hit a golf ball so that the ball flies airborne and straight, including a tee shot with a driver. A new golf club with the shaft attached to the heel of the club head as in conventional golf clubs, but with the shaft angle increased to about 65-90° is disclosed. Also disclosed are golf clubs and putters having a shaft attached at or near the center of the club or putter head. | 02-27-2014 |
| 20140378243 | GOLF CLUB CONFIGURED FOR MULTIPLE ADJUSTABILITY - In some embodiments, an adjustable putter includes a club body defining a substantially planar face for striking a golf ball, and a hosel including a hosel neck and a hosel adapter configured to be received within a hosel chamber defined by the club body. The hosel adapter defines an interior channel. The adjustable putter also includes a shaft attachable to the hosel neck, and a housing column. The hosel adapter is configured to rotate about the housing column so as to adjust a lie angle of the hosel neck, and the hosel chamber is configured to prevent rotation of the hosel adapter from increasing the lie angle beyond a predetermined value. | 12-25-2014 |
| 20160059086 | GOLF PUTTER WITH CONSTRAINED ADJUSTABILITY - Disclosed are systems and methods of adjusting the playing orientation of the head of a golf club. An adjustment to the axis of the shaft in reference to the vertical plane is constrained within minimum and maximum limits, so as to conform to current and proposed changes to the United States Golf Association (USGA) rules of play. The fine adjustment within these constraints cannot be readily made, and all adjustable parts are firmly fixed, so there is no reasonable likelihood of them working loose during a round. The adjustments to the club are designed such that during a stipulated round, the playing characteristics of a club cannot be purposely changed by adjustment or by other means. | 03-03-2016 |
| 20160184661 | Adjustable putter and related methods - An adjustable putter that allows a golfer to quickly and easily adjust the lie and angle of a putter. The adjustable putter features a ball and socket joint connection that allows a golfer to adjust the shaft of a putter within the upper socket opening. The adjustable putter allows a golfer to articulate the angle of the putter relative to the putter head without affecting the putter grip's alignment with the putter face. Inside the shaft is a torque tube with a set pin that enters a sphere within a socket, which causes the sphere to expand and frictionally fit into the socket to lock the putter shaft in place. In an alternative embodiment, the torque tube assembly that may be of various lengths, where a male connection tool may enter the side of the putter shaft at any point. It is at that point where the female hex connection of the torque tube assembly will be positioned for use with the male tool. Additionally, the adjustable putter allows a golfer to adjust the loft of the putter via different loft plates that may be inserted into a loft cavity at the bottom of the putter. | 06-30-2016 |
