DETAILED DESCRIPTION
In the following detailed description, reference is made to the accompanying drawings that show, by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It is to be understood that the various embodiments of the invention, although different, are not necessarily mutually exclusive. Furthermore, a particular feature, structure, or characteristic described herein in connection with one embodiment may be implemented within other embodiments without departing from the scope of the invention. In addition, it is to be understood that the location or arrangement of individual elements within each disclosed embodiment may be modified without departing from the scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims, appropriately interpreted, along with the full range of equivalents to which the claims are entitled. In the drawings, like numerals refer to the same or similar functionality throughout the several views.
In a golf swing, including a putting stroke, there is an address position, a back stroke, and a through stroke. The address position is when the club is at rest, at an approximate center point of a golfer's stance. The back stroke is the portion of the golf stroke when a golfer moves the club from the address point back towards the right hand side of a right handed golfer, or the left hand side of a left handed golfer. The through stroke is the portion of the swing from the furthest point of the back stroke, through the address point, and forward towards the left hand side of a right handed golfer and the right hand side of a left handed golfer. An inside along an arc stroke path refers to either a back stroke or a through stroke which is taken back or forward along an arc that curves in towards a golfer's body.
There are many theories on putting methods and techniques. One theory is that a golfer should take a putter straight back in the back stroke, and then follow straight through towards the target in the through stroke. This theory, when put into practice, results in the putter head following a straight line that is substantially in line with a target throughout the stroke. Another technique uses an inside along an arc in the back stroke, and an inside along an arc in the through stroke. The path that the putter head travels in this instance is roughly an arc. Many consider this the most natural putting stroke, perhaps because it is similar to the arc that a golfer makes in a full golf swing.
The inventor of the present subject matter has developed new putting strokes, and apparatuses to assist a golfer in learning, practicing, and perfecting these new putting strokes. The new putting strokes include an inside along an arc back stroke and a straight down the line towards the target through stroke, and an inside along an arc back stroke, a straight down the line towards the target for a first portion of the through stroke, and an inside along an arc for a second portion of the through stroke.
FIGS. 1, 2, and 4 illustrate example embodiments of a golf stroke training device. The device 100 includes a base 110 and a vertical guide 120. The vertical guide 120 is substantially perpendicular to the base 110. The base 110 and vertical guide 120 can be of unitary construction. The base 110 and vertical guide 120 can also be separate pieces coupled together by fasteners, welds, solders, or any means of attachment known in the art. The device 100 includes a first section 130, and a second section 140. The first section 130, when viewed from the top as illustrated in FIG. 2, forms an arc that extends from an approximate midpoint 150 of the device 100 to an endpoint 160 of the device 100. The second section 140, when viewed from the top as illustrated in FIG. 2, forms a substantially straight edge that extends from the approximate midpoint 150 to a second endpoint 170 of the device 100. In another embodiment, as illustrated in FIG. 4, the second section 140, when viewed from the top, forms a substantially straight edge that extends from the approximate midpoint 150 to a point 155 along the second section 140, and then from the point 155 to the second endpoint 170, the section 140 follows an inside along an arc line. The length of the section from the approximate midpoint 150 to the point 155 can vary from as little as a couple of centimeters to 30 centimeters or more. When viewed from a side or a perspective view as illustrated in FIG. 1, it can be seen the that height of the vertical guide 120 at the approximate midpoint 150 is at a minimum, the height of the vertical guide 120 is greater at the endpoint 160 of section 130, and the height of the vertical guide 120 is at a maximum at the endpoint 170 of section 140. In another embodiment, the height of the vertical guide 120 is at a maximum at the endpoint 160. Varying the height of the vertical guide 120 along its length affects the putting stroke as described later herein. The base 110 includes holes 180 for receiving fasteners that can attach the device 100 to a surface. The device 100 can be attached to any surface, including a backyard, a floor in a family room, or a putting green.
In a particular use of the device 100, the arc extending from the approximate midpoint 150 to the endpoint 160 (when viewed from the top as in FIG. 2) represents an inside along an arc putting back stroke wherein a golfer draws a putter back and towards himself thereby forming an arc. The straight line from the approximate midpoint 150 to the second endpoint 170 (as further illustrated in FIG. 2) represents a straight follow through towards the target in the through stroke of a putting stroke. The height of the vertical guide 120 represents the vertical path of the club head in the novel inside along an arc back stroke and the straight line of the through stroke, and the vertical guide 120 guides the club head through this path.
In another use of the device 100, the arc extending from the approximate midpoint 150 to the endpoint 160 (when viewed from the top as in FIG. 4) represents an inside along an arc putting back stroke wherein a golfer draws a putter back and towards himself thereby forming an arc. The straight line from the approximate midpoint 150 to the point 155 (as further illustrated in FIG. 4) represents a straight follow through towards the target in a first portion of the through stroke of a putting stroke. Then, after passing the point 155, the device 100 guides a golfer's putting stroke along an inside along an arc path to the second endpoint 170. The height of the vertical guide 120 represents and guides the vertical path of the club head in the novel inside along an arc back stroke, the straight line of a first portion of the through stroke, and an inside along the arc second portion of the through stroke.
The device 100 can be used in connection with training a golfer to execute a proper golf stroke, and in particular, a proper putting stroke. For example, to use the device 100 to train a golfer's putting stroke, the device 100 can be attached to a putting green, one's living room floor, or any other suitable surface. When a typical putting surface is used, any simple type fasteners, including golf tees, can be inserted through the holes 180 in the base 110 of the device 100, and into the putting surface. After securing the device 100 to the putting surface, a golfer stands on the base side of the device as shown by the outline of the feet 190 in FIGS. 2 and 4. The golfer grips a putter, and places it into the address position wherein the heel of the putter is in contact with the vertical guide 120 at the approximate midpoint 150. Then, with or without a ball to strike, the golfer draws the club back so that the heel of the putter remains in contact with the first section 130, and after reaching the farthest point of the back stroke, moves the putter head forward to return the putter head to the approximate midpoint 150, through the straight edge section 140, and to the second endpoint 170. In the embodiment of FIG. 4, the golfer once again grips a putter, and places it into the address position wherein the heel of the putter is in contact with the vertical guide 120 at the approximate midpoint 150. Then, with or without a ball to strike, the golfer draws the club back so that the heel of the putter remains in contact with the first section 130, and after reaching the furthest point of the back stroke, moves the putter head forward to return the putter head to the approximate midpoint 150, through the straight edge section 140 to the point 155 in the section 140, and then from the point 155 along the inside arc to the second endpoint 170. By keeping the heel of the club in contact with the first section, a golfer learns an inside along an arc back stroke. By keeping the heel in contact with the second section 140, a straight line towards the target through stroke is learned. In the embodiment of FIG. 4, a straight line towards the target followed by an inside along an arc through stroke is learned. These putting strokes result in straighter more accurate putts.
The height of the vertical guide 120 at the approximate midpoint 150, at the endpoint 160 of the section 130, and at the endpoint 170 of the section 140, trains a golfer to follow the vertical path of the new putting strokes. The vertical path of the new putting strokes starts out low at the address of the ball (approximate midpoint 150), rises along the inside arc during the back stroke up to point B in FIG. 1, returns down along the inside arc to the approximate midpoint 150, and gradually rises up along the inside arc in the through stroke to the point A at endpoint 170 of section 140. As noted above, the heights of the vertical guide 120 at the endpoints 160 and 170 can vary, which can be used to alter the putting stroke to suit the particular needs of each golfer.
FIGS. 3 and 5 are flowcharts illustrating the steps in these methods of golf putting strokes.
The device 100 can be used with virtually any style putter including standard length putters, belly putters, and long putters; blade putters, mallet putters, and Anser-like putters; and many putter faces including steel, polymer insert, grooves, and bumps. The device 100 can be used irrespective of the particular putting grip of a golfer including overlap, reverse overlap, cross hand, and claw grips.
