Definitions

  • This invention relates to a curved hosel putter. Specifically this invention relates to improvements made to golf clubs used as putters.
  • a conventional short putter is between 84 and 90cm in total length, and has a single grip, located at the top end of the shaft.
  • the player grasps the single grip with both hands when putting the ball with the putter-head which strikes the ball.
  • a putter has a "lie-angle", defined as the angle between the shaft, and horizontal, when the club is measured in a normal playing position.
  • Common lie-angles preferred by golfers are between 79.5 degrees and 68 degrees from horizontal or the ground line. Having the correct lie-angle is important as it will better allow the putter-head to pass over the putting green reliably, without either the heel or toe end of the underside of the putter snagging, or catching, on the ground causing a poor putt.
  • the heel end of the putter-head is the end closest to the golfer's feet when using the putter and the toe end of the putter-head is the end farthest from the golfer's feet when using the putter.
  • putters Whilst a few putters only have three parts i.e. grip, shaft and putter-head, most putters have four parts, namely: the grip, the shaft, the putter-head and a "hosel".
  • a hosel is that part of the putter which joins the putter-head to the shaft.
  • Hosels are usually substantially straight in their middle section with bends at one or both ends.
  • Some putters do not have hosels and the shaft is merely inserted and glued into a hold in the putter-head.
  • a golfer may wish to adjust the lie-angle by bending the hosel or shaft of the putter.
  • Most golfers do not have the equipment, knowledge, experience or confidence to attempt line angle adjustments themselves as there is a risk of breaking the putter.
  • a putter could be designed to allow the golfer to adjust the putter's lie-angle and for the resultant putter to meet the Rules of Golf and thus be legal for competition play.
  • Putters when assembled with their putter-head, shaft and grip may be grouped as one of the three following groups:
  • the centre of gravity is the single point which the result of the gravitational forces acting on all the individual particles of the putter acts. This point coincides with the putter's centre of mass.
  • a centre-balanced putter is a putter where the attached shaft points directly to the centre of gravity of the putter-head.
  • the shaft would point exactly to the centre of gravity in the x, y and z planes. Whilst this is available it is far more popular to have a face-balanced putter.
  • a face-balanced putter is a putter, that when the attached shaft is rested horizontally and balanced towards the shaft tip (perhaps on a horizontally orientated fulcrum such as an out stretched finger), will exhibit the property of the putter face being parallel to the ground.
  • a "Ram Zebra” brand putter is a well known face-balanced putter.
  • the putter will rest with the toe of the putter hanging down.
  • a "Ping Anser” brand putter is a very well known heel-balanced putter. When putting a ball on a flat putting green the target is the golf hole, and on a sloping green the hole will not be the target but in the following discussion the target is the hole.
  • the ball-target line is the line from the ball to the target.
  • the COG-target line is the line from the centre of gravity of the putter-head (or putter-head and hosel where there is a hosel) to the target.
  • COG-indicia commonly a dot or a line on the top of the putter to inform the golfer of the location of the COG-target line.
  • this may serve to not only mark the "sweet-spot” location, but also may aid the golfer to aim the putter correctly at the target.
  • the sweet-spot is the point where the COG-target line intersects the putter face.
  • a putt “feels” better when there is less vibration, or twisting and there is better energy transfer on impact with the ball.
  • the putter When the putter (with zero face loft for this discussion) is in use the putter is placed behind the ball with the putter face facing the target and the COG-target line is then parallel to the ball-target line.
  • CAD computer aided design
  • the shaft has a finite diameter (commonly 9 to 12mm) and therefore obscures the golfers view of the COG-indicia aiming line from above.
  • the shaft then bends back towards the heel of the putter-head, the shaft has a single bend and is known as such.
  • COG-target line is divided by the entry of the shaft directly into the putter-head or it must be very short and less useful to the golfer for the important aiming task.
  • a golf putter including
  • hosel wherein the hosel is attached at one point in the vicinity of the heel end of the putter-head and at another point to the shaft
  • a golf putter including
  • a curved hosel wherein the hosel is attached at one point in the vicinity of the heel end of the putter-head and at another point to the shaft,
  • the hosel is configured as an arc of a circle.
  • Hosel used throughout the present specification should be understood to mean the part of the putter which connects the shaft to the putter-head.
  • the hosel is curved along at least part of its length.
  • COG- indicia target line should be understood to mean the line on the putter-head that indicates the line from the centre of gravity of the putter-head (or putter-head and hosel if fitted) to the target.
  • the hosel is permanently attached to the putter-head.
  • the hosel is removable from the putter-head.
  • the position of the hosel with respect to the putter-head is adjustable.
  • the amount of adjustment is limited so that the putter will not fall outside of the "Rules of Golf".
  • the adjustment can be smooth or may be in steps by using physical construction detailing such as teeth, ribs, notches etc.
  • the hosel is secured to the putter-head by a locking mechanism such as that disclosed in NZ Patent Application No. 526630.
  • the curved hosel is secured into a complementarily curved recess within the putter-head.
  • the curved hosel is configured as an arc of a circle which has its centrepoint at the putters' centre of gravity. It should be appreciated that, due to the geometry of the hosel, it is adjusted in position with respect to the putter-head to alter the lie-angle whilst maintaining its centrepoint at the putters' centre of gravity.
  • centrepoint will be at a different position and not at the putter's centre of gravity.
  • the hosel has a specifically shaped cross-section (such as a dovetail) and is fitted into a complementarily shaped slot within the putter-head.
  • the hosel contains perforations or other voids which will reduce the weight of the putter and assist in improving its balance.
  • the aim of the present invention is to achieve a putter balance that is as close as is possible to being perfectly balanced.
  • the prevent invention allows for the construction of a strong centre-balanced, or face-balanced, putter which provides the golfer with a clear and unimpeded view of the COG-indicia target line.
  • hosel position is adjustable is that the lie-angle can be adjusted for a golfer with no (or minimal) effect on the balance of the putter.

  • Figure 5 is a diagrammatical representation of a preferred embodiment of the present invention.
