PUTTER WITH AIMING ARMS

Technical Field

The present invention relates to a golf putter having arcuate shaped aiming arms that are positionable between a forward aiming position and a rearward aiming position. The present invention also relates to arcuate shaped aiming arms which are removably attached to a golf putter face in a forward aiming position

Background of the Invention

Golf putters having aiming arms for practice putting aid in lining up a golf ball with a golf hole cup. These devices have an aiming pointer attachable to an existing putter head by a clip or temporary fastener. They must take into consideration a variety of factors affecting its attachment to putters of different styles while assuring accurate alignment on the putter. Detachable aiming arms have the convenience of allowing the putter to be used in regulation play, but this feature also allow the aiming arms to be forgotten or misplaced. Examples of such are U.S. Patent Nos. 3,698,093 to Marshall, 4,002,343 to Eckert, 4,647,045 to Bilyeu and 5,810,675 to Weathers.

Other practice putters have aiming pointers that are permanently attached. For the putters having a permanently affixed pointer forward of the face, a problem arises in regulation play where no part of the putter head may be forward of the face. Examples of such are U.S. Patent Nos. 4,650,191 to Mills and 7,247,102 to Hayd and U.S. Patent Application Publication No. US2006/0030419. For putting devices having only a rearward positioned pointer, visual alignment of the ball path to the hole is more difficult as seen in U.S. Patent Nos. 4,741,535 to Leonhardt and 7,326,121 to Roake.

Aiming arms allow a golfer to practice putting using aided visual alignment. Aided visual alignment provides the golfer a more precise reference for subsequent putts and will allow the golfer to quickly improve alignment of his putts. However, once the golfer has improved his putting performance, he is often forced to then remove an attachment or switch to a regulation putter during normal play. This often interrupts the golfer's concentration and rhythm. ^'

It would be beneficial for the golfer to have a putter with an aiming device which allows alignment of the ball path to the hole with as much visual accuracy as possible, and which does not interrupt the golfer's flow of play. Disclosure of Invention

Mode(s) for Carrying Out Invention

In describing the preferred embodiment of the present invention, reference will be made herein to Figs. 1 -14 of the drawings in which like numerals refer to like features of the invention. Figs. 1-4 show the preferred putter of the present invention, having a pair of aiming arms in a direction corresponding with the desired direction of the ball. This configuration of the putter head assembly is referred to as the aiming mode. A golf putter head comprises an elongated body 1 2 having a central axis 18 along the length thereof and a pair of pointing arms 14, each arm pivotally connected at opposing body ends 16a, 16b. The arms pivot angularly about the central axis between a forward aiming position and a

second position away from the forward aiming position. The elongated body and the aiming arms make up the putter head assembly. A shaft 20 is disposed on a top surface 22 of the elongated body.

The elongated body includes a face 30 upon which a golf ball 99 is struck. The face is planar and substantially perpendicular to the ground and to shaft 20, providing the ball 99 with a horizontal force when struck with the face 30. A second surface 32 opposite the face may also planar and perpendicular to the ground, allowing the putter to be used by a left-handed golfer as well as a right-handed golfer. A bottom surface 36 extends between the face 30 and the second surface 32 opposite the face. A top surface 38 extends between the face and the second surface 32 and preferably includes a center aiming line 40.

Each of the aiming arms 14 preferably has a wide body portion 22 and an outwardly extending pointing member 24. The pointing member has a substantially uniform height h corresponding to the height of the elongated body, and extends from the wide body portion a distance sufficient to allow visual aiming. The aiming arms 14 include aiming indicating lines 44a, 44b that may be printed or scored, parallel with the outer edge of the aiming arms. The spacing between the aiming lines 44a, 44b corresponds with the diameter of a regulation golf hole cup. Visual aiming is defined from the perspective of the golfer as he would be positioned directly above the putter head in taking a stroke, visualizing a straight path from the putter to the hole cup 74, lining up the visual lines 66, 68 created by aiming lines 44a, 44b. The aiming arm includes a respective concave arcuate portion 26, 28 between the pointing member and an area forward the plane of the face 30 as identified when the aiming arms are in a forward aiming position or a forward pointing direction. The arms in the forward aiming position allow the golfer to orient the arcuate portions 26, 28 of the aiming arms with the corresponding regulation diameter of the golf hole cup while lining up his shot using visualization lines 62, 64, 66, 68.

Th e bottom surface 36 is curved upward toward the body ends so that when the putter head contacts the ground, the center portion of the putter body is in contact with the ground and the body ends are positioned above the ground to allow rotation of the aiming arms. Fig. 5 shows the aiming arms 14 of the putter rotated away from the forward aiming position and in a rearward pointing direction. With the arms in this rearward aiming position the golfer may line up the putt by visualizing a straight line 64, 66 along the outer edge of the aiming arm. The line extended from this visualized straight line is the lined up with the edge of the cup. The center line 40 engraved into the top of the outer head in a direction perpendicular to the putter face may also be used as an aid in lining up the putt.

The pivoting aiming arms 14 are adapted to pivot about the central axis 18 between a forward aiming position and a second position away from the forward aiming position. This second position may be in an upward facing position. However, in the preferred embodiment of the putter shown in Fig. 6, the second position away from the forward aiming position is the rearward aiming position, also called the rearward pointing direction. Rotational arrows 100 show the rotational movement of the aiming arms as they are re- positioned from the rearward aiming position to the forward aiming position.

The putter preferably also includes a control mechanism comprising a lever adapted to rotate the pivoting arms or to allow their rotation. The lever causes rotation of the pivoting arms from the forward aiming position to a second position, or normal mode, away from the forward aiming position. The lever mechanism may be adapted to pivot the aiming arms between the forward aiming position and the rearward aiming position.

In one embodiment of the control mechanism shown in Figs. 7-10, the putter includes an axle 50 that connects the pivoting arms 14a, 14b to one another so they rotate in unison. The axle is generally a smooth and round elongated rod which passes slidingly through an axle sleeve 48 in the putter body 12, the axle ends 54a, 54b extend outward from the body ends 16a,

16b, connecting to the aiming arms 14a, 14b in corresponding aiming arm openings 72, 76. The axle ends may be shaped to allow each end to be slid into the corresponding aiming arm opening 72, 76 where it may be fastened using a set screw tightened through a threaded hole 98 extending from outward of the body to the axle end. The axle ends may alternately be attached to the aiming arms with a snug press fit or adhesive. The axle 50 includes an axle groove 52 between the axle ends positioned in contact with the shaft 20. The lower end of the shaft includes a shaft slot 58 and fits slidingly in a shaft sleeve 82 within the putter body 12. A compression spring 80 seats at the bottom of the shaft sleeve and urges the shaft in an upward direction. Aiming arm opening 76 is sized to enclose a torsion spring 70 having a positioning pin at both ends, the first pin end inserted in a pin aperture 75 inside the aiming arm opening 76, the other positioning pin inserted in a pin aperture 74 on the body end 16b. When the aiming arm is rotated in one direction, a rotational force is generated by the torsion spring 80 in the opposite direction. The putter includes a drag washer 56 on the axle 50, frictionally contacting aiming arm 14a and the putter body end 16a. The drag washer dampens the rotational movement of aiming arm 14a so that the tension created by the torsion spring will affect a smooth rotational movement.

Fig. 10a shows the preferred embodiment of the golf putter with pivoting aiming arms. The putter includes an axle 50' which connects the pivoting arms 14a, 14b to one another so they rotate in unison. The axle passes slidingly through an axle sleeve 48 extending horizontally in the putter body 12, and the axle ends 54a, 54b extend outward from the body ends 16a, 16b, connecting to the aiming arms 14a, 14b in corresponding aiming arm openings 72, 76. The axle ends are fastened to the aiming arms using a set screw 200 tightened through a threaded hole 98 of the aiming arms. The axle 50' includes an axle groove 52' between the axle ends which opens downward when the aiming arms are in the forward aiming position. The lower end of the shaft 20 includes a shaft slot 58' positioned at the lower end

of the shaft whereby the axle passes through the shaft slot. The shaft slot includes a shaft slot tab 202 protruding upward from the bottom of the slot. A leaf spring 204 attached to the lower end of the elongated body, preferably using fasteners 206, urges the shaft in an upward direction. Aiming arm openings 72, 76 are sized so that each encloses a spiral torsion spring 70 through which the axle 50' passes. Each spring 70 has a positioning pin at each end with the first pin end inserted in a pin aperture 75 inside the aiming arm openings 72, 76, and the opposite positioning pin end inserted in one of the pin aperture 74 on the body ends 16a, 16b. Multiple pin apertures 74 concentrically placed around openings 72, 76 provides for more accurate tuning of the tension on the aiming arms. When the aiming arm is rotated in one direction, to move the aiming arms into a forward aiming position, a rotational force is generated by the torsion spring 80 in the opposite direction. The axle groove 52' engages the shaft slot tab 202 when the shaft 20 is in its raised position, thereby locking the aiming arms in the forward aiming position against the force of the torsion spring. Urging the shaft downward disengages the shaft slot tab from axle groove, allowing the torsion spring to rotate the aiming arms from the forward aiming position to the second position, preferably the rearward aiming position. Limit pins 212 protruding from the elongated body ends engage arcuate limit grooves 214 in the aiming arms such that the aiming arms may rotationally swing only upward and prevent the aiming arms from rotationally swinging downward. The limit pins and limit grooves additionally provide the limit position at the rearward aiming position when the shaft groove tab 202 is released from the axle groove 52'.

The golf putter may include a bottom cover attached to the lower end of the elongated body, enclosing the leaf spring 204 between the bottom cover 210 and the elongated body 12. The bottom cover additionally provides separation of the aiming arms from the ground so that the aiming arm corners do not catch the ground during rotation. Preferably, the aiming arms are aluminum.

In another embodiment of the putter and control mechanism shown in Figs. 7-10, downward pressure on the shaft provides the rotation energy for the aiming arms to rotate from the normal mode to the forward aiming position rather than the energy being supplied by manual rotation. In an alternate embodiment of the putter, the rotation of the aiming arms may be achieved using a small electric motor in the putter body, activated by an electrical switch in the shaft.

In assembling the putter described in the embodiment above, the shaft 20 is inserted into the shaft sleeve 82, the downward force on the shaft compressing the compression spring 80 and positioning the shaft slot 58 near the axle sleeve 48. The axle 50 is then slid into the axle sleeve 48 where a potion of the axle is positioned within the shaft slot 58. Releasing the downward pressure on the shaft allows the compression spring to urge the shaft upward until the lower end of the shaft slot seats on a portion of the axle groove 52. Each of the aiming arms is then fastened to the end of the axle protruding from the body. As shown in Fig. 8, at least one of the aiming arms includes a limit pin 90 that corresponds to a limit pin groove 92 on the body end. The limit pin allows the aiming arm 14a, 14b to move from the forward aiming position to the normal position in an upward arc. The limit pin does not allow the aiming arm to rotate in the reverse arc where the pointing member 24 would be forced into the ground.

In a method for using the putter shown in Figs. 7-10, the golfer manually rotates the spring loaded aiming arms 14a, 14b to the forward aiming position. A flat portion of the axle groove 52 will then be in a position to allow the shaft 20 to engage the axle groove, the compression spring 80 urging the shaft upward and locking the aiming arms in the forward aiming position. The golfer may then, after lining up the putt, push downward on the shaft as shown in Fig. 1 1 along directional arrow 93, disengaging the shaft slot from the axle groove, releasing the axle 50 from its locked position. The aiming arms rotate upward and then rearward as shown by directional arrow 94, the rotational speed being governed by friction generated by the drag

washer 56. The limiting pin 90 will prevent the aiming arms from rotating beyond the normal position.

In a method for using the golf putter shown in Fig. 10a, the golfer manually rotates the spring loaded aiming arms 14a, 14b to the forward aiming position, aligning the axle groove 52' with the shaft slot tab 202. This alignment allows the tab 202 to engage the axle groove 52' by the leaf spring 204 urging the shaft upward and thereby locking the aiming arms in the forward aiming position. The golfer may then, after approaching the ball and lining up the putt, push downward on the shaft 20 disengaging the shaft slot tab 202 from the axle groove, releasing the axle 50 from its engaged position. The aiming arms rotate upward and then rearward until the limiting pin 21 2 and limiting groove 214 prevents the aiming arms from rotating beyond the second position, preferably the rearward aiming position. The golfer then strikes the ball toward the golf hole cup. In another embodiment of the putter, a lever will additionally control the rotation of the arms 14a, 14b between the rearward aiming position and the forward aiming position so that manual rotation of the aiming arms is not necessary.

In another embodiment of the present invention shown in Figs. 1 2-14, the aiming arms are manually removably attached to a putter face. The aiming arms are attachable to the face of the putter in a position whereby the arcuate surfaces of opposing aiming arms are directed toward each other and the outline of the paired arcuate surfaces correspond to the diameter of a regulation golf hole. As shown in Fig. 12, the aiming arms 200a, 200b are attachable to the face 1 94 of a putter body 190 with a hook and loop fabric connector 210, 21 2, the hook portion 210a, 210b associated with the rear surface of the aiming arms and the corresponding loop portion 21 2a, 212b associated with the putter face 1 94. Alternately the hook portion is associated with the putter face and the corresponding loop portion associated with the rear surface of the aiming arms. The fabric may be permanently attached to the putter face

or the rear surface of the aiming arms or preferably the fabric is attached by an adhesive which has a higher breakaway force than that of the hook and loop connection. One example of the hook and loop fabric is Velcro. The aiming arms 200a, 200b are attachable to any putter face wherein one side of the hook and loop fabric is attachable to the putter face by the user. Alternately a putter may be provided which accepts the aiming arms. A shaft 198 is attached to the putter body 190.

Figs. 13 and 14 shows the aiming arms 200' attachable to the putter face with an alignment clip connector 300. The clips 300 protrudes from the rear surface 206 of the aiming arms and are insertable and securable into corresponding openings 306 on the putter face 194'. The clip 300 comprises a tension portion 308 which maintains force against the corresponding opening 306 and the clip urges alignment of the aiming arms in a position whereby the aiming arms have opposite and inward facing arcuate surfaces and the arcuate surfaces correspond to the outline of a golf hole cup. A shaft 198' is attached to the putter body 190'.

Alternately, a clip on the aiming arm is adapted to fictionally attach to the putter body. The clip may be a bracket to grasp near an upper surface or ends of the putter body. In a method of using the putter with pivoting aiming arms according to the present invention, Figs. 1 and 4 show the preferred positions of the aiming arms 14a, 14b in each of the user modes. The golfer may use the aiming mode only for aligning the golf putt. Once the putt is aligned, the golfer rotates the aiming arms 14a, 14b to the normal, rearward-facing mode for striking the golf ball 99. In earlier stages of training, the golfer may choose to strike the ball while the aiming arms are in the aiming position, without using the putter in the normal mode. The putter according to the present invention allows the golfer to decide when he is ready for putting with the arms in the rearward aiming direction or in the second position.

In this arrangement the golfer continues to use the putter for practice, deciding how to use the aiming arms to his benefit, while being able to use the same putter he has been practicing with in regulation play.

In another embodiment of the method for using the putter shown in Fig. 1 , the golfer ensures the aiming arms of the putter are in the aiming position and then approaches the ball 99. The "approach" is defined as the motions taken by a golfer to move toward the ball and take a stance in a direction for strike the ball toward the golf hole. The golfer then lines up the shot by visualizing the aiming arms extended in a straight line along the corresponding pointing member. The golfer then operates the lever such that the aiming arms rotate to the rearward aiming position and takes the shot.

In an alternate embodiment for using the putter, the golfer ensures the aiming arms 14a, 14b of the putter are in the aiming position, lines up the shot by visualizing the aiming arms extended in a straight line along the corresponding pointing member 24 and then takes the shot. In the preferred embodiment of the invention wherein the aiming arms 14a, 14b have an arcuate portion 26, 28, the golfer visualizes the arcuate portions of the aiming arms 26, 28 with the corresponding diameter of the golf hole cup while lining up his shot using aiming indicators 44a, 44b on the top surfaces of the aiming arms and visualization lines 62, 64, 66, 68. If the putt to be attempted requires a backswing distance or an amount of force which increases the chance the golf ball being struck off the center of the putter face, after lining up the shot and before taking the shot the golfer preferably operates the lever such that the aiming arms rotate to the normal mode rearward aiming position, decreasing his chances of hitting the ball with one of the arcuate surfaces 26, 28 on the aiming arms 14a, 14b.

In a method of training the golfer, the putter may be used solely in the aiming mode during initial stages of training. As the golfer progresses to a next training stage, the aiming arms are removed or positioned in the normal mode just prior to taking the shot to allow the golfer to get used to putting in the normal mode. In a final stage of training or in regulation play, the putter

may be maintained in the normal position. This method of training allows the progression of the golfer to be easily managed, from using the putter as a training aid to using the putter to play a regulation round of golf, all with the same putter. Thus, the present invention achieves the objects described above. The invention provides a putter with a pair of aiming arms at opposite ends of the putter face which allow the golfer ^" to set up a putt using the aiming arms, change the position of the aiming arms from a forward aiming position to a rearward aiming position, and then take the shot, all without having to bend over or lift the putter to change the position of the arms.
