Golfers are continually attempting to improve their putting strokes and many devices have been developed in an effort to help golfers in this endeavor. However, no one training device has fulfilled the needs of all golfers, and new training devices are continually being developed in an effort to provide golfers with improved and interesting training techniques. The present putting trainer attempts to provide golfers with a previously unknown training device offering golfers an interesting and effective method for practicing and improving their putting strokes.




SUMMARY OF THE INVENTION




It is, therefore, an object of the present invention to provide a putting trainer. The putting trainer includes a substantially flat plate upon which a golfer may place and strike a golf ball. The plate includes a first end having a recess shaped and dimensioned for receiving a golf ball and maintaining the golf ball in position adjacent the first end until such a time that the golfer strikes the golf ball toward a second end of the plate. The plate further includes a central alignment groove extending from the golf ball recess toward the second end of the plate, the central alignment groove providing a desired alignment direction for a golfer striking a golf ball sitting within the recess. The putting trainer also includes a plurality of obstacles respectively and selectively positioned within a plurality of indents formed within the plate. The indents are positioned on opposite sides of the central alignment groove at a position between the recess and the second end of the plate to define a passageway through which a golf ball is desirably struck as a golfer attempts to hit the golf ball from the first end of the plate toward the second end of the plate, wherein the indents are shaped and dimensioned such that obstacles placed therein are readily dislodged when a struck golf ball veers from the central alignment groove and strikes one of the obstacles.




It is also an object of the present invention to provide a putting trainer wherein the plurality of obstacles are balls.




It is a further object of the present invention to provide a putting trainer wherein the plurality of indents are dimples respectively shaped and dimensioned to receive the balls.




It is another object of the present invention to provide a putting trainer wherein the first end includes a first edge adjacent the recess, the recess being positioned relative to the first edge such that a rear edge of a golf ball sitting within the recess is aligned with the first edge, allowing a golfer to align a putter with the first edge as the golfer addresses the golf ball prior to putting.




It is still another object of the present invention to provide a putting trainer wherein the recess is approximately 0.84 inches from the rear edge.




It is yet a further object of the present invention to provide a putting trainer wherein the central alignment groove is visible to a golfer standing over the plate.




It is also an object of the present invention to provide a putting trainer wherein the first edge includes an open cut section extending from the first edge toward the golf ball recess. The open cut section is defined by opposed upwardly inclined walls such that a ball rolled within the open cut section toward the recess will roll up the opposed upwardly inclined walls and into the recess.




It is another object of the present invention to provide a putting trainer wherein the opposed upwardly inclined walls angle toward each other as they extend from the first edge toward the recess.




It is a further object of the present invention to provide a putting trainer wherein the opposed upwardly inclined walls define a substantially V-shaped open cut section.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




The detailed embodiments of the present invention are disclosed herein. It should be understood, however, that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, the details disclosed herein are not to be interpreted as limited, but merely as the basis for the claims and as a basis for teaching one skilled in the art of how to make and/or use the invention.




With reference to

FIGS. 1

to


6


, a putting trainer


10


in accordance with the present invention is disclosed. The putting trainer


10


includes a substantially flat plate


12


upon which a golfer may place and strike a golf ball


14


. The plate


12


is preferably formed of polycarbonate and has a thickness of 0.093 inches. The plate


12


is further provided with recesses


16


along its underside


18


in which inserts may be positioned for advertising the origin of the putting trainer


10


or providing golfers with instructions regarding the use of the putting trainer


10


. While specific materials and dimensions are disclosed above with reference to the present putting trainer, those skilled in the art will appreciate the possible variations in material, thickness, shape, etc. that may be made without departing from the spirit of the present invention. For example, it is contemplated that the plate may be manufactured from aluminum or other break-resistant materials of different weights.




As mention above, the plate


12


includes an underside


18


. The underside


18


is provided with a downwardly extending stake


20


. The stake


20


is shaped and dimensioned to facilitate secure location of the present putting trainer


10


to an underlying support structure (such as a putting green or an indoor room carpet). The stake


20


is generally positioned directly below a golf ball supporting recess


22


, thereby allowing the plate


12


to be readily rotated about the stake


20


when a golfer wishes to realign the putting trainer


10


. The plate


12


further includes a topside


24


, a first end


26


and a second end


28


.




The first end


26


of the plate


12


includes a centrally positioned golf ball supporting recess


22


shaped and dimensioned for receiving a golf ball


14


and maintaining the golf ball


14


in position adjacent the first end


26


until such a time that the golfer strikes the golf ball


14


toward the second end


28


of the plate


12


. The topside


24


of the plate


12


further includes a central alignment groove


30


extending from the recess


22


, and the open cut section


32


(to be discussed below in greater detail), toward the second end


28


of the plate


12


. The central alignment groove


30


provides a desired straight-line starting direction for a golfer striking a golf ball


14


sitting within the recess


22


and is preferably formed to be readily visible to a golfer standing over the present putting trainer


10


. In addition, the alignment groove


30


is readily visible to a golfer both from behind the plate (to help in setting the plate precisely in proper alignment on a putting surface) and from above (to help a golfer learn proper appearance of desired putting direction line from actual putting position).




With the foregoing in mind, the central alignment groove


30


is painted white to enhance visibility. However, other colors (for example, red, yellow or other “stand-out” colors) may be used without departing from the spirit of the present invention. In addition, those skilled in the art will certainly appreciate that painting of the groove may be replaced with other coloring techniques, for example, tape.




In accordance with a preferred embodiment of the present invention, the alignment groove


30


is milled to a depth of 0.05 inches with a width of 0.109 inches. However, these dimensions are merely used in accordance with a preferred embodiment of the present invention, and other dimensions may certainly be used without departing from the spirit of the present invention.




As discussed above, the recess


22


is shaped and dimensioned for receiving and maintaining a golf ball


14


in position adjacent the first end


26


of the plate


12


. The recess


22


is positioned in line with the alignment groove


30


and, as such, is centrally positioned on the present plate


12


. The functionality of the present putting trainer


10


is further enhanced by positioning the recess


22


at a specific distance from the first edge


34


of the first end


26


. Specifically, the recess


22


is positioned relative the first edge


34


such that a rear edge


36


of a golf ball


14


sitting within the recess


22


is aligned with the first edge


34


. Since the first edge


34


is substantially perpendicular to the central alignment groove


30


along which a golfer attempts to hit a golf ball


14


in accordance with the present invention, the positioning of the recess


22


a predetermined distance from the first edge


34


allows a golfer to align a putter face


38


with the first edge


34


as the golfer addresses the golf ball


14


prior to putting. In this way, a golfer may square the face


38


of the putter along the first edge


34


to ensure a proper set up prior to beginning his or her putting stroke.




Since a golf ball is approximately 1.68 inches in diameter, it is preferred that the center of the recess


22


be positioned a distance of 0.84 inches from the first edge


34


. However, this distance may be varied slightly where different diameter golf balls are used for various purposes. Similarly, those skilled in the art will appreciate that the recess may be moved further from or closer to the first edge where a specific training technique so dictates.




Use of the first edge


34


as an alignment mechanism is further facilitated by beveling the first edge


34


of the plate


12


as the topside


24


extends toward the underside


18


of the plate


12


. The bevel provides for a smooth transition between the underside


18


and the topside


24


of the plate


12


, allowing a golfer to smoothly strike a golf ball


14


with a putter without worrying that the putter will strike a flush edge. In addition, the beveled edge of the first edge


34


is colored white to enhance visibility and provide golfers with a readily visible mark by which he or she may align the face of a putter.




As mentioned above, the first edge


34


also includes an open cut section


32


extending from the first edge


34


toward the recess


22


. The open cut section


32


is defined by opposed upwardly inclined walls


42


such that a ball


14


rolled within the open cut section


32


toward the recess


22


will roll up the opposed upwardly inclined walls


42


and into the recess


22


. In accordance with a preferred embodiment of the present invention, the opposed upwardly inclined walls


42


angle toward each other as they extend from the first edge


34


toward the recess


22


, defining a substantially V-shaped open cut section


32


.




A plurality of obstacles


44


are respectively positioned within a plurality of indents


46


shaped and dimensioned for receiving the obstacles


44


. The indents


46


are positioned on opposite sides of the central groove


30


at a position between the recess


22


and the second end


28


of the plate


12


. The indents


46


define a passageway through which a golf ball


14


rolls as a golfer attempts to hit the golf ball


14


from the first end


26


of the plate


12


toward the second end


28


of the plate


12


, and out onto the putting surface along the intended alignment direction. The indents


46


are shaped and dimensioned such that obstacles


44


placed therein are readily dislodged when a struck golf ball


14


veers from the central groove


30


and strikes one of the obstacles


44


.




Where a golfer hits a ball


14


such that it passes between the opposed obstacles


44


, he or she knows the ball


14


was struck square and on-line. However, when the golf ball


14


strikes an obstacle


44


, the golfer knows an error occurred during his or her putting stroke causing the ball


14


to roll left or right off course.




In accordance with a preferred embodiment of the present invention, the obstacles


44


are balls, for example, marbles, steel balls, or brass balls, which are maintained within the indents


46


until such a time that they are struck by a golf ball


14


passing thereby. While balls are used in accordance with a preferred embodiment of the present invention, other obstacles, for example, cylindrical posts, square blocks, nubs, etc. may be used.




As shown in the Figures, and in accordance with a preferred embodiment of the present invention, three indents


46


and three obstacles


44


may be respectively positioned on each side of the alignment groove


30


. The obstacles


44


and indents


46


are positioned adjacent the second end


28


of the plate


12


, a predetermined distance from the recess sufficient to test the putting skills of a golfer using the present putting trainer. In addition, the indents


46


taper inwardly as they extend toward the second end


28


, thereby increasing the difficulty as obstacles


44


are positioned within different indents


46


. While three sets of indents and obstacles are disclosed in accordance with a preferred embodiment of the present invention, more or less indents/obstacles may be employed without departing from the spirit of the present invention.




Referring to

FIG. 1

, a laser


48


may be used in conjunction with the present putting trainer


10


to ensure adequate alignment with a target


50


beyond the plate


12


. The laser


48


is used by placing the laser


48


within the alignment groove


30


and allowing the laser


48


to direct a laser light toward, and onto, a target


50


.
