A GOLF PUTTER

BACKGROUND QF THE INVENTION:

This invention relates to a golf putter. Particular attention is given to putterhead of the golf putter.

Recently we invented and patented a novel putting aid called the R ² Line & Length Putting Device (PCT/IB2004/002860). This Device provides a very effective method of perfecting ones putting technique, improving both strength and accuracy. Whilst trying to perfect the R ² Line & Length Putting Device and hitting literally millions of putts, certain ideas occurred to us regarding the physical properties of an ideal golf putter. We have therefore designed a golf putter, which we believe will be compatible with both the R ² Line & Length Putting Device and with traditional grass putting surfaces.

A second independent invention, which has recently been approved by the Royal & Ancient Rules Committee, takes the marking of a conventional golf ball to its logical conclusion. This invention entails clipping a plastic jig onto a conventional golf ball so that an aiming line can be drawn right around its circumference. This aiming line is usually drawn along the same line as the golf ball manufacturers primary or secondary logo. Once on the putting surface it is standard practice for the golfer to mark his/her golf ball. The golfer would then replace the golf ball with the aiming line directed to the intended target he/she wishes to hit the golf ball. This target could be straight at the golf hole or aimed off depending on any anticipated lateral movement of the golf ball due to slope and/or nap. Thus this aiming line provides a definitive line along which the golfer can establish his target line. This independent invention inspired us and thus it is the object of our invention to provide a novel and innovative method of utilising the golf ball manufacturers primary and secondary logos and the drawn on aiming line on the golf balls circumference to the golfers maximum advantage.

SUMMARY OF THE INVENTION:

According to the first aspect of the present invention there is provided a golf putterhead being partially or totally transparent (translucent).

Typically, the golf putterhead will be manufactured from a transparent (translucent) material including glass, laminated glass, toughened glass, perspex, polycarbonate or any other clear or transparent polymer.

Preferably, the golf putterhead will be manufactured from glass, crystal glass or toughened glass.

Advantageously, the glass has been heat-treated and is shatterproof.

According to the second aspect of the invention there is provided for a golf putterhead having scientifically positioned lines and markings (also called positioning and aiming matrices) on the top and/or bottom and/or sides and/or anywhere inside the transparent golf putterhead.

Typically, these scientifically positioned lines and markings would be inscribed, engraved, painted or burnt (in a multitude of colours) on the top and/or bottom and/or sides and/or anywhere inside the transparent golf putterhead.

Advantageously, these scientifically positioned lines and markings on the golf putterhead are accurately positioned so that once lined up correctly in the eyes of the golfer, his/her body and eye position and that of the golf putterhead are automatically fixed in the correct position (also called parallax positioning).

The scientifically positioned lines and markings can be marked in many different matrices dependant on the designers and golfers preferences.

Having conducted a Patent Search through Patent Attorneys Spoor & Fisher, we have concluded that the third and fourth aspects of our Provisional Patent (No. 2006905352) are considered to be novel and innovative in our PCT Application.

According to the third aspect of the invention there is provided for a golf putterhead having a 45-degree prism towards the rear of the putterhead, which forms part of the finished shape of a totally functional transparent golf putterhead.

Preferably, the golf putterhead is manufactured from glass, crystal glass or toughened glass.

Advantageously, the glass has been heat-treated and is shatterproof.

Typically, the 45-degree prism forms part of a totally functional glass golf putterhead. The 45-degree. prism is hence an integral part of the golf putterhead itself from a design, construction and material point of view and is thus not a reflective appendage to the golf putterhead.

The 45-degree prism is positioned so that the golfer can see a reflected image through the top of the golf putterhead of the whole or part of the ball being putted.

The 45-degree prism enables the golfer to position himself/herself in preparation for the putt and accurately line up the putter face perpendicular to the target line which he/she has provided by carefully aligning the logos or aiming line marked on the golf ball with his/her target.

The 45-degree prism does not allow the golfer to see the golf hole or flagstick as the image of the golf ball will always eclipse the image of any item positioned behind it. Hence the 45-degree prism is not able to show the golf ball position in relation to the

golf hole or flagstick, as is the case in patents where a mirror or prism protrudes above or to the side of the golf putterhead.

According to the fourth aspect of the invention there is provided for a golf putterhead having certain areas selectively sandblasted, beadblasted or machined. By selectively sandblasting areas of the glass putterface, the top of the golf putterhead or the 45- degree prism itself - it is possible to limit the size, shape and clarity of the image of the golf ball.

Typically, any number of shapes and sizes could be sandblasted onto the glass putting face, the top of the golf putterhead or the 45 -degree prism. Usually these sandblasted areas of the putterhead should allow only those desired markings on the golf ball to be reflected to the eyes of the golfer. Therefore the aiming line marked on the golf ball or the manufacturers logos, which have been aimed in the intended direction of the putt, will be the only thing reflected to the eyes of the golfer.

Preferably, the glass putting face would be the part of the golf putterhead sandblasted as it would provide instant grip on the golf ball when hit. This would encourage the immediate roll of the ball and prevent the ball from skidding.

According to the fifth aspect of the invention there is provided a glass golf putterhead with rounded (spherical) cutouts at the back of the putterhead.

These rounded (spherical) cutouts were designed and shaped so as to facilitate the easy retrieval of the R ² Line & Length putting practice sliding ball back to its "start" position on the R ² Line & Length Putting Device.

According to the sixth aspect of the invention there is provided a glass golf putterhead with a plastic or fibre covering on the bottom of the putterhead.

Typically, the plastic or fibre covering on the bottom of the glass golf putterhead is designed to dampen the noise where the bottom of the putterhead comes into contact with the toughened glass surface of the R ² Line & Length Putting Device.

Advantageously, this plastic or fibre covering on the bottom of the glass golf putterhead will also minimise the damage where the bottom of the putterhead comes into contact with the toughened glass surface of the R ² Line & Length Putting Device, unlike a conventional putter.

Also shown is a view from the bottom of the putterhead where the fixing groove blind hole or hole 45 would be. Also shown is the straight line 59 inscribed or painted on the bottom of the putterhead. Hence this straight line 59 has replaced the R ² Line & Length logo 46 from Drawing No. 2, Figure 4. Also shown is the putterface 47 at the front of the putterhead. Lastly, Figure 8 shows the spherical or curved cutouts 60 in the putterhead. These spherical or curved cutouts 60 were designed to retrieve the R ² Line & Length sliding ball whilst using the R ² Line & Length Putting Device.

Turning to Figure 9 a top view of the transparent golf putterhead is shown. Also shown is the parallax positioning line 49 inscribed or painted on the top of the putterhead. The straight line 59 from Figure 8 (which has been inscribed or painted on the bottom of the putterhead) has now replaced the R ² Line & Length logo 46 from Drawing No. 2, Figure 5. The golfer will position his/her eyes so that the parallax positioning line 49 completely eclipses the straight line 59 thus ensuring the eyes are directly above the centre of the putterhead (this is known as the parallax positioning system). Additionally this will also ensure that the bottom of the putterhead will be "square" with the putting surface. Also shown is the "cross-hairs" 50 inscribed or painted on the top of the putterhead above the reflective surface of the 45-degree prism. Lastly, Figure 9 shows a golf ball in plan with its manufacturers primary logo (Titleist) 51 and an aiming line 52 drawn around its circumference in line with the Titleist logo.

The R ² Line & Length sliding ball would have a flat sliding disc 55 at its' bottom instead of the bottom of a conventional golf ball 53. The R ² line & Length sliding ball would be used on the toughened glass surface 56 of the R ² Line & Length Putting Device.

Referring to Drawing No.4: Putterhead (Improvement to the Provisional Patent of September 2006).

Turning to Figure 12 a bottom view of the transparent golf putterhead is shown. Also shown is the 45 -degree prism 43 towards the rear 44 of the putterhead. Also shown is the putterface 47 at the front of the putterhead.

Turning to Figure 13 (Top View) a top view of the transparent golf putterhead is shown. Also shown is the 45 -degree prism 43 towards the rear of the putterhead. Also shown is a golf ball in plan with its primary logo (Titleist) 51 provided by the manufacturer. Also shown is an aiming line 52 drawn around its circumference along the same line as the primary logo (Titleist) 51. This aiming line 52 has been coloured in red (instead of black) on the back of the ball at A. The image of the back of the ball (with the vertical red line at its centre) at A passes horizontally through the transparent golf putterhead to the 45-degree prism at B where it is reflected vertically up to the eyes of the golfer. The golfers' eyes have already been correctly positioned by the parallax positioning system previously mentioned (Drawing No.2; Figure 5). The golfer then adjusts the putterhead until the red line coincides with the "crosshairs" 50 above the 45-degree prism 43 and then knows that the putterhead is in line with the chosen target. In other words the putterface 47 is now perpendicular to the target line. This should now explain the novel and innovative principles on which this putterhead is based and how it utilises the manufacturers primary and secondary logos and the drawn on aiming line around the balls circumference.

Turning to Figure 13 (Side View) a side view of the transparent golf putterhead is shown. Also shown is the image of the vertical red aiming line 52 at the back of the ball passing from the ball at A, horizontally through the transparent putterhead to the 45-degree prism 43 at B and then vertically through the "cross-hairs" 50 to the eyes of the golfer at C. This should now explain the novel and innovative principles on which this putterhead is based.

Turning to Figure 14 a front view (front elevation) of the transparent golf putterhead is shown. Also shown is the putterface 47 in contact with a conventional golf ball or a R ² Line & Length sliding ball. Finally, the aiming line 52 at the front of the ball (which is black) is shown.

Referring to Drawing No.5: Putterhead (Improvement to the Provisional Patent of September 2006).

Turning to Figure 15 a front view (front elevation) of the transparent golf putterhead is shown. Also shown is the putterface, which has been selectively sandblasted 62

making it possible to limit the size, shape and clarity of the image of the ball. Also shown is the "line" area left clear 63 on the putterface which should allow only those desired markings on the golf ball to be reflected to the eyes of the golfer. Therefore the aiming line marked on the golf ball or the manufacturers logos, which have been aimed in the intended direction of the putt, will be the only thing reflected to the eyes of the golfer. Alternatively, the putterface could have been beadblasted or machined to get the same desired effect. It is preferable that the putterface is sandblasted, beadblasted or machined, as it would provide instant grip on the golf ball when hit. This would encourage the immediate roll of the ball and prevent the ball skidding.

Turning to Figure 16 a. top view of the 45-degree prism. The top of the 45-degree prism has been selectively sandblasted 64 making it possible to limit the size, shape and clarity of the image of the ball reflected through it. The "line" area left clear 65 on the top of the 45-degree prism should allow only those desired markings on the golf ball to be reflected to the eyes of the golfer. Therefore the aiming line 66 marked on the golf ball 69 or the manufacturers logos (from Drawing No.5, Figure 19), which have been aimed in the intended direction of the putt, will be the only thing reflected to the eyes of the golfer. Alternatively, the top of the 45-degree prism could have been beadblasted or machined to get the same desired effect.

Turning to Figure 17 & side view of the transparent golf putterhead with the 45-degree prism at its' rear; Figure 18 a bottom view of the 45-degree prism and Figure 19 a view of the back of the golf ball with the aiming line around its circumference. The bottom of the 45-degree prism has been selectively sandblasted 67 making it possible to limit the size, shape and clarity of the image of the ball reflected through it. The "line" area left clear 68 on the bottom of the 45-degree prism should allow only those desired markings on the golf ball to be reflected to the eyes of the golfer. Therefore the aiming line 66 or the manufacturers logos marked on the golf ball 69, which have been aimed in the intended direction of the putt, will be the only thing reflected to the eyes of the golfer. Alternatively, the bottom of the 45-degree prism could have been beadblasted or machined to get the same desired effect.

Typically, any number of shapes and sizes could be sandblasted onto the glass puttingface, the top of the golf putterhead or the bottom of the 45-degree prism. As seen in Drawing No.6.

Referring to Drawing No.6: Putterhead (Improvement to the Provisional Patent of September 2006).

Turning to Figure 20 a front view (front elevation) of the transparent golf putterhead is shown. Also shown is the putterface, which has been selectively sandblasted 70, making it possible to limit the size, shape and clarity of the image of the ball. Also shown is the " cross" area left clear 71 on the putterface which should allow only those desired markings on the golf ball to be reflected to the eyes of the golfer. Therefore the "cross" marked on the golf ball or the manufacturers logos, which have been aimed in the intended direction of the putt, will be the only thing reflected to the eyes of the golfer. Alternatively, the putterface could have been beadblasted or

machined to get the same desired effect. It is preferable that the putterface is sandblasted, beadblasted or machined, as it would provide instant grip on the golf ball when hit. This would encourage the immediate roll of the ball and prevent the ball skidding.

Turning to Figure 21 a top view of the 45-degree prism. The top of the 45-degree prism has been selectively sandblasted 72 making it possible to limit the size, shape and clarity of the image of the ball reflected through it. The "cross" area left clear 73 on the top of the 45 degree prism should allow only those desired markings on the golf ball to be reflected to the eyes of the golfer. Therefore the "cross" 74 marked on the golf ball 75 or the manufacturers logos (from Drawing No.6, Figure 24), which have been aimed in the intended direction of the putt, will be the only thing reflected to the eyes of the golfer. Alternatively, the top of the 45-degree prism could have been beadblasted or machined to get the same desired effect.

Turning to Figure 22 a side view of the transparent golf putterhead with the 45-degree prism at its' rear; Figure 23 a bottom view of the 45-degree prism and Figure 24 a view of the back of the golf ball with the "cross" marked on it. The bottom of the 45- degree prism has been selectively sandblasted 76 making it possible to limit the size, shape and clarity of the image of the ball reflected through it. The "cross" area left clear 77 on the bottom of the 45-degree prism should allow only those desired markings on the golf ball to be reflected to the eyes of the golfer. Therefore the "cross" 74 or the manufacturers logos marked on the golf ball 75, which have been aimed in the intended direction of the putt, will be the only thing reflected to the eyes of the golfer. Alternatively, the bottom of the 45-degree prism could have been beadblasted or machined to get the same desired effect.

Typically, different types of shapes and sizes could be sandblasted onto the glass puttingface, the top of the golf putterhead or the bottom of the 45-degree prism depending on the golfers wishes and how the golfer wishes to mark his/her golf ball.
