Definitions

  • the present invention relates to an alignment aid for use when playing golf and more particularly, but not exclusively, to an alignment aid for use when putting.
  • the two main requirements for a successful putt are: i. the face of the putter to be square at impact; and ii. the palm of the right hand (for a right-handed golfer) to move along the line of the putt after impact, albeit for a relatively brief time.
  • the "yips” is characterised by a tentative putting stroke, often for short putts, leading to an offline putt at the wrong pace as the putt, while tentative, can also become too quick.
  • the "yips” typically result from an inability to achieve neuromuscular control of the putting stroke and is a matter of the brain sending the "wrong” message. In neurological terms, it is an "action induced occupational dystonia".
  • the present invention provides a marking of a defined form on the ball to be used in conjunction with defined markings on a putter to enable accurate alignment and on-line putts by consistently squaring the putter face at impact and which also assists in overcoming the "yips" and improves short putting.
  • the ball thus marked may also be used in conjunction with a driving club either with or without corresponding marking to facilitate improved alignment on tee shots.
  • a golf ball having an alignment system, the system comprising a rectangular marker, the sides of which are defined by lines, the line defining one of the sides of the rectangle being thicker than the lines defining other sides of the rectangle, the rectangle being of such a size that the entirety of the rectangle can be viewed from above by a player with the ball in a playing position, and a direction alignment marker extending forwardly relative to the thicker line of the rectangular marker and at right angles thereto whereby when the ball is positioned with the alignment marker extending in the intended direction of the shot, the thicker line of the rectangular marker will be at the forward side of the rectangle and perpendicular to the intended direction of the shot.
  • a golf club having an alignment system for co-operation with that of the golf ball defined above, the alignment system of the club comprising a rectangular marker visible by a player from above with the club in the address position, the sides of the rectangle being formed by lines, with the line defining one of the sides of the rectangle being thicker than the lines defining other sides of the rectangle, the rectangular marker being so arranged that the thicker line is immediately adjacent to, and parallel to, the club face when viewed from above and is forwardly of the other lines defining the rectangle, the width of the rectangular club marker as considered in a direction perpendicular to the intended direction of the shot being substantially the same as that of the rectangular ball marker as considered in the same direction.
  • each rectangular marker in the row is of substantially the same width, and hence of substantially the same width as the rectangular ball marker and each of the rectangular markers is defined by lines of which one is thicker than the others and lies at the forward side of the rectangle in the intended direction of the shot.
  • the ball In a putting stroke, the ball is set up with its direction alignment marker extending forwardly in the intended direction of putt, and the putter is placed so that its rectangular marker(s) is aligned with that of the ball. The player then executes the shot while concentrating on the thicker line of the ball marker while putting.
  • the visualised alignment of the row of two or more rectangular markers as provided by the rectangular marker on the ball and the or each marker on the club enables accurate alignment of the club face and also assists in squaring the club face at impact and achieving an on-line follow through.
  • the neurophysiology involves the visual cortex and visual memory and bypasses the dysfunctional motor pathways thought to be responsible for the "yips", as the dimensions, number, and positioning of the rectangles are easily recognised by the visual cortex and are retained for the duration of the shot.
  • the rectangles are defined by two pairs of lines of unequal length and thereby of oblong shape with the two longer sides being oriented at right angles to the intended line of the shot whereby each rectangle is elongate in its width-wise direction.
  • the thicker line in the rectangular ball and club markers will be the forward one of the two longer lines. This facilitates the setting up of the markers on the club which might have only limited depth for placement of the markers.
  • the rectangular markers could alternatively be defined by sides of equal length and thereby of square shape.
  • the alignment system also has applicability to tee shots.
  • the upper surface of the head of a driving "wood” or a so-called utility club may carry the row of rectangular markers but even absent that, an unmarked driving club can be used in conjunction with the ball played off the tee by aligning the bottom edge of the club with the thicker long edge of the rectangular ball marker.
  • the upper edge of an iron could carry a single rectangular marker for use when the club is played off the tee.
  • a golf ball having a first marking for alignment with the face of a golf club, and a second marking transverse to the first marking for alignment with the intended direction of a shot.
  • the first marking is a line marking arranged to extend parallel to the face of the golf club. More preferably, the first marking includes a rectangle having a pair of opposite lines for alignment with the face of the golf club. Even more preferably, the second marking includes a direction alignment marker extending perpendicularly from one of said pair of opposite lines. In one form, the direction alignment marker extends perpendicularly from a location substantially midway along the length of said one of the opposite lines. Preferably, the direction alignment marker extends forwardly from said one of the opposite lines.
  • the direction alignment marker extends forwardly from a front one of said pair of opposite lines. It is preferred that the front line is thicker than the lines defining other sides of the rectangle.
  • a similar rectangle is provided on the head of the golf club for alignment with the rectangle of said first linear marking.
  • the similar rectangle may be provided on the face of the iron.
  • Figure 1 is a plan view showing a golf ball and putter each having an alignment system in accordance with the preferred embodiment of the invention
  • Figure 2 shows schematically the rectangular marker as used on the ball and the club
  • Figure 3 is a plan view similar to Figure 1 but shown applied to a different form of putter.
  • Figure 4 is a plan view showing the ball used in conjunction with a "wood" carrying the alignment system.
  • the ball With reference to Figure 1 there is shown the ball with its rectangular marker 2 with the thicker forward edge 4, and a direction alignment marker 6 extending forwardly from the edge 4 at right angles thereto from the centre of that edge.
  • the interior of the rectangle 2 on the ball carries no markings and has the same colour as that of the remainder of the ball.
  • the lines defining the rectangle 2 and alignment marker 6 are preferably of dark blue or black and which on a white object with a basic background of green are clearly and comfortably adopted by the visual cortex.
  • the particular putter shown has a row of three rectangular markers 2a, 2b, 2c similar to that of the ball, with the thicker edge 4a, 4b, 4c being at the front and parallel to the face of the putter.
  • the edge 4a of the forward rectangle 2a of the row is immediately adjacent the plane of the putter face.
  • the lines defining each rectangle are coloured as previously discussed in relation to that on the ball and the interior of each rectangle is preferably white.
  • rectangles on the ball and club are of the same width (as considered in a direction at right angles to direction of the shot) but are not necessarily all of exactly the same length (as considered in the direction of the shot).
  • the length of the leading rectangle 2a has to be adapted to sit within the depth of the upper edge of the club immediately behind the front face whereas the other two rectangular markers are on a lower surface rearwardly of the face and are not thereby subject to an inherent length restriction.
  • the rectangular markers on the ball and club are approximately of uniform size and have an approximately uniform spacing so that the distance between the ball rectangle 2 and forward club rectangle 2a (in the address position) is approximately the same as that between rectangles 2a and 2b, and 2b and 2c.
  • the longitudinal spacing between the rectangles is preferably about 10mm.
  • the size of the rectangles is principally determined by the size of a rectangle which can clearly be viewed on the ball. Based on golf industry research in relation to the optimum size of logos for imprinting onto the dimpled spherical surface of golf balls to achieve a sharp image, it has been determined that the best results are achieved when the length (1) of the rectangle is 11mm and the width (w) is 23mm, making an area of 253mm 2 which equates with that which is considered to be ideal for a logo according to industry research; accordingly it may be said that the preferred area will be approximately 250mm .
  • the table below defines with reference to Figure 2 preferred ranges and optimum sizes for the rectangles on the ball and the club together with thicknesses of the lines defining the rectangles. It is to be noted that the line thickness A for the thicker forward side of the rectangle is a significant factor in preventing optical illusion.
  • the ball is set up with the direction alignment marker 6 aimed in the direction of the putt and the putter is then aligned by aligning its rectangular markers 2a, 2b, 2c with that,
  • Figure 3 shows the alignment system applied to a smaller headed putter with only two rectangular markers.
  • Figure 4 illustrates the alignment system consisting of two rectangular markers applied to the top surface of a "wood" for improved alignment when driving from the tee.
  • it is not essential in that mode for the club itself to carry the markers, although that is preferred; satisfactory alignment for the purposes of a tee shot can be achieved by setting up the shot with the bottom edge of the club aligned with the forward side of the rectangle on the ball.
  • the alignment system can also be applied to the head of an iron or a so-called utility club, for use when driving from the tee.
  • a so-called utility club for use when driving from the tee.
  • just a single marker will be applied to the upper edge of the head, whereas utility clubs will normally have a top surface which would permit application of a row or two or possibly three markers.
  • the alignment system can be applied to the ball either during manufacture or post- manufacture by printing in the same way that customised logos are printed onto balls post- manufacture.
  • the alignment system could be applied to the ball using an appropriate part-spherical stencil and a permanent marker pen or similar.
  • the rectangular markers on the club head can be incorporated at the time of manufacture or alternatively can be supplied as a self-adhesive cut-out for application to an existing putter head possibly in conjunction with a suitable template for accurate alignment during placement of the marker. This would be the preferred option in the case of a wood, utility club or iron.
  • the front line of the rectangle is described as being thicker than the lines defining other sides of the rectangle, it will be understood that this may not always be the case in other forms of the invention in which, for example, a rear line of the rectangle may (also) be thicker than lines defining other sides of the rectangle.
  • the direction alignment marker is described as extending forwardly relative to the thicker line of the rectangle, in other examples it may extend rearwardly relative to the thicker line (instead of or in addition to extending forwardly of the thicker line).
