Peripheral-weighted putter head
A golf putter head having a toe and a heel. The putter head has a face defining a ball-striking portion and lateral portions extending from the ball-striking portion toward the toe and the heel. There is a rear section spaced from the face, and a connecting section extending from the ball-striking portion of the face to the rear section. A pair of elongated weights, one weight coupled at one end to each of the lateral portions of the face at locations equidistant from the ball-striking portion, and each weight also coupled at its other end to the rear section, accomplish balanced peripheral weighting. The weights are preferably replaceable.

FIELD OF THE INVENTIONThis invention relates to a golf putter.
BACKGROUND OF THE INVENTIONIt is known that peripheral-weighted putters can assist with maintaining proper alignment of the putter through the swing and contact with the ball. However, many of these putter designs have a substantial bottom face area that can easily touch the ground during the swing, either by improper downward motion of the putter head, or a slight transverse rocking of the head. Another drawback is that the substantial area greatly increases the drag of the putter when the head moves through longer grass on the fringe of the green.
Yet another disadvantage of many of these putters is that the overall weight and the weight distribution relative to the face are fixed. Such putters with adjustable weight designs typically have one or more cavities that can accept weights placed therein. However, the club head material that creates the cavity itself adds weight. Also, since the cavities are fixed in size, the weights must have a particular diameter. Both of these factors inherently limit the weight range achievable with such putters.
SUMMARY OF THE INVENTIONIt is therefore an object of this invention to provide a peripheral-weighted putter head that can be tilted transversely without contacting the putting surface.
It is a further object of this invention to provide such a peripheral-weighted putter head in which the peripheral-weighting is adjustable over a wide range.
It is a further object of this invention to provide such a peripheral-weighted putter head with reduced drag as the head is moved through grass.
This invention features a putter head that allows a golfer to draw a “direct line” mental image from the putter-head to the target without the need to create a perpendicular line from the face, as the player would from a traditional blade or mallet style putter. The main body is in a cylindrical shape to allow accurate and precise ball striking. This cylindrical main body shape is divided down the middle by a gap, or space from top to bottom that starts directly behind the face and separates the body into two halves thereafter. This separation or division provides equalized balancing on off center ball strikes, as well as to facilitate alignment of the head and ball with the target or intended line. The main body is parallel with the axis to the intended target line, which also aids with target alignment. The invention also encourages the user to concentrate on the center of the putter face since that is the largest contact area of the face and is smaller than the diameter of the golf ball.
The putter head also has counterbalance weights on each side, directly behind the heal and the toe of the face that run transversely to the back of the putter head and parallel to the intended target line. These weights prevent twisting of the putter head if contact with the ball is made off center on the putter face as well as providing most of the putter head weight. The side weights are interchangeable which allows for heavier or lighter putter head weight. The putter also allows the golfer to putt from the second cut or heavy fringe due to the unique face and body designed to flow though the higher grass without substantial drag.
This invention features a golf putter head having a toe and a heel. The putter head has a face defining a ball-striking portion and lateral portions extending from the ball-striking portion toward the toe and the heel. There is a rear section spaced from the face, and a connecting section extending from the ball-striking portion of the face to the rear section. A pair of elongated weights, one weight coupled at one end to each of the lateral portions of the face at locations equidistant from the ball-striking portion, and each weight also coupled at its other end to the rear section, accomplish balanced peripheral weighting. The weights are preferably replaceable.
The weights are preferably removably coupled to both the face and the rear section, to allow their replacement. The removable coupling is preferably accomplished with threaded connecting members. The face, the rear section and the connecting section are preferably unitary. The lateral width of the face and of the rear section are preferably about the same, and the connecting section preferably has a lateral width that is about the same as the ball-striking portion. The ball-striking portion is preferably substantially circular, in which case the connecting section is preferably substantially cylindrical along at least a part of its length.
The connecting section may define an elongated slot along its top, and the slot may extend through the thickness of the connecting section, to divide the connecting section into two part cylinders. The rear section may comprise two distinct portions, one integral with each part cylinder. The two distinct portions of the rear section may lie essentially at right angles to the slot. The connecting section may be flattened at its lower circumferential region, and the lateral portions of the face may not be as high as the cylinder, to define narrowed wings extending from the ball-striking portion. The lower edges of the wings may rise up along their length toward the heel and toe, in which case the weights are connected near the tips of the wings.
The weights may have a substantially circular cross-section. The substantially circular cross-section preferably extends along at least much of the length of the weights, or even along effectively the entire length of the weights. The diameter of the weights may vary along their length. The diameter of the weights is preferably largest near their center, and tapers from the largest point toward the front that is coupled to the face and toward the back that is coupled to the rear section. The taper of the weights toward the front is in one embodiment greater than it is toward the back.
The golf club putter head further comprises a hosel for accepting a club shaft. Preferably, the hosel is in the connecting section.
Also featured is a golf putter head having a toe and a heel, comprising a face defining a substantially circular ball-striking portion, and narrowed lateral portions extending from the ball-striking portion toward the toe and the heel, a rear section spaced from and essentially parallel to the face, and a connecting section extending from the ball-striking portion of the face to the rear section, wherein the face, rear section and the connecting section are unitary. There is also a pair of removable elongated weights, one weight removably coupled at one end to each of the lateral portions of the face at locations equidistant from the ball-striking portion, and each weight also removably coupled at its other end to the rear section, to accomplish balanced peripheral weighting.
