Abstract
A golf putting training controls golf ball momentum into a delivery site by first absorbing momentum of indeterminate magnitude and thereafter allowing the ball to move along a controlled or sloped path under influence of gravity. As a result, the ball enjoys consistent momentum and alignment upon arrival at the delivery site. The delivery site can be a kick-back device operating more consistently when receiving a ball moving along a consistent approach path and with consistent momentum. The delivery site can also be a golf ball return area whereat a golf ball is desirably returned consistently to a given region thereof.
Description




BACKGROUND OF THE INVENTION




The present invention relates to sports-training devices and, more particularly, to a golf-training device for putting and including a ball return system.




Golfers practice both on the golf course and off the golf course to hone skills and improve scores. Golf training aids offer to the golfer an opportunity to practice golfing skills without actually going to a golf course or even leaving the home or office. Among the wide variety of such golf training aids, putting practice training devices are both notable and popular. Golfers can practice putting indoors on carpeting with a simulated target. While a simple target, e.g., an overturned glass or designated spot on the carpet, serves for a given single putt, the golfer typically putts multiple times at the target and desires that the ball consistently return to a given position from which a next putt may be executed. Furthermore, the golfer typically desires that the target simulate an actual golf cup or hole.




Thus, desirable putting practice training devices allow the golfer to target an actual hole and thereby simulate putting on a real golf course. Typically, these devices include a kick-back device propelling the golf ball back to the golfer whether the golfer hits the target or not, i.e., returns the ball to the golfer whether or not the golfer successfully drops the ball in the hole or cup.




U.S. Pat. No. 5,102,141 issued Apr. 7, 1992 to L. E. Jordan and entitled


GOLF PUTTING PRACTICE DEVICE


illustrates a golf-training device. The golfer putts a ball from one end of a flat area and across the flat area toward a slightly inclined ramp. The ball climbs the ramp and reaches a plateau including a target hole. An open and inclined capture trench lies laterally across and borders the back of the plateau behind the hole. Any ball going past the hole falls in the capture trench. The well or bottom of the hole couples by tunnel, i.e., under the surface of the plateau, to a mid-portion of the capture trench. Thus, any ball reaching the plateau either falls in the capture trench, i.e., when the golfer misses the putt, or falls in the hole and then reaches the capture trench by way of the tunnel. Because the return trench is inclined, the ball moves laterally therein. The trench terminates immediately adjacent to a kick-back device, i.e., a kick-back device located at the capture trench outlet. The kick-back device includes a trigger and plunger. When the ball hits the trigger, the kick-back device activates the plunger and the plunger strikes the ball to propel it longitudinally, i.e., back toward the golfer, along a return gutter. The return gutter terminates at a side-kick structure converting the longitudinal momentum of the ball into lateral momentum. More particularly, the ball strikes a rounded or diagonally oriented surface deflecting the ball from its longitudinal path along the gutter into and along a lateral path toward the flat area. The ball desirably comes to rest at the front of the flat area in position for a second putt toward the hole.




Unfortunately, such kick-back devices do not consistently propel the ball along its return path. In some cases, the ball simply does not properly engage the trigger and the device fails to activate the plunger. In other cases, the plunger does not consistently strike the ball and the kick-back device imparts inconsistent momentum along the return path. Because the longitudinal return momentum is inconsistent, when the side-kick structure converts it to lateral momentum the final resting place for the golf ball is indeterminate. In other words, the ball does not always return to the same spot in the putting area. Thus, when the ball does return to the flat area it typically comes to rest at substantially different locations from one putt to the next putt due to inconsistent delivery momentum along its return path.




It would be desirable to provide, therefore, a putting practice device more reliably and consistently returning the golf ball to the golfer. The subject matter of the present invention provides such a golf putting and ball return system.




SUMMARY OF THE INVENTION




The present invention controls golf ball momentum by first absorbing momentum of indeterminate magnitude and then allowing the golf ball to move under influence of gravity. In some cases, a controlled path directs the ball at key times to establish a consistent travel path.




A fundamental problem with prior art golf putting training aids is the lateral approach of the ball at the kick-back device. A lateral approach fails to consistently trigger the kick-back device or position the ball consistently for engagement by the plunger.




Under the present invention, however, the ball approaches the kick-back device longitudinally along a controlled path and under influence of gravity to consistently activate the trigger and to consistently position the ball for engagement by the plunger. As a result, the ball consistently activates the kick-back device and the kick-back device plunger imparts consistent momentum to the ball.




The invention also applies to ball return to the putting area whereby indeterminate magnitude longitudinal delivery momentum is absorbed and new and controlled lateral momentum returns the golf ball consistently to a given region of the putting area.




The subject matter of the present invention is particularly pointed out and distinctly claimed in the concluding portion of this specification. However, both the organization and method of operation of the invention, together with further advantages and objects thereof, may best be understood by reference to the following description taken with the accompanying drawings wherein like reference characters refer to like elements.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




The present invention controls momentum by first absorbing momentum of indeterminate magnitude and then allowing the golf ball to move under influence of gravity. In some cases, a controlled path directs the ball at key times to establish consistent movement. A fundamental problem with prior art golf putting training aids is the lateral approach of the ball toward the kick-back device. A lateral approach fails to consistently trigger the kick-back device or position the ball consistently for engagement by the plunger. Under the present invention, however, the ball approaches the kick-back device longitudinally along a controlled path and under influence of gravity to consistently activate the trigger and to consistently position the ball for engagement by the plunger. As a result, the ball consistently activates the kick-back device and the kickback device plunger imparts consistent momentum to the ball.





FIG. 1

illustrates a first embodiment of the present invention, a golf putting training device


10


. Device


10


includes a plateau


12


and a target hole


14


. A putting area


16


lies in front of plateau


12


and a ramp


18


lies intermediate of putting area


16


and plateau


12


. Putting area


16


can be the floor or carpet upon which device


10


rests or can be a mat, or other such putting surface structure, integral to device


10


. In any case, a golfer places a golf ball


20


in putting area


16


, strikes the golf ball


20


, and attempts to drop the golf ball


20


in hole


14


. If well putted, ball


20


travels along putting area


16


, up ramp


18


, onto plateau


12


, into hole


14


, and reaches well


14




a


of hole


14


. Should golf ball


20


miss hole


14


, however, a capture trench


30


lies across the back of plateau


12


and receives golf ball


20


therein. Each end, i.e., left end


30




a


and right end


30




b


, of capture trench


30


inclines downward and laterally inward toward a trench well


30




c


. Thus, golf ball


20


travels in trench


30


laterally inward and eventually reaches well


30




c.






A discharge chute


40


couples well


14




a


of hole


14


to a return gutter


44


. Any golf ball


20


reaching well


14




a


rolls under influence of gravity laterally along chute


40


and into return gutter


44


at ball discharge site


46


. As may be appreciated, chute


40


lies under plateau


12


as a tunnel structure and does not interfere with travel of ball


20


across plateau


12


. An inclined tunnel


50


, also located under plateau


12


, couples well


30




c


of trench


30


to chute


40


, i.e. any golf ball


20


reaching well


30




c


rolls along tunnel


50


, into chute


40


and eventually reaches ball discharge site


46


of return gutter


44


. Thus, plateau


12


, hole


14


, trench


30


, tunnel


50


, and chute


40


serve as a ball-capture structure carrying any ball


20


reaching plateau


12


eventually to discharge site


46


of return gutter


44


. Important to note, the lateral momentum of ball


20


substantially dies at discharge site


46


when ball


20


travels laterally into gutter


44


and hits side wall


44




a


thereof at site


46


.




A conventional kick-back device


60


lies at the distal end of return gutter


44


. As best seen in

FIG. 2

, return gutter


44


includes a reverse slope section


44




b


between site


46


and kick-back device


60


. Section


46


slopes downward toward kick-back device


60


. Device


60


includes a trigger


60




a


and a plunger


60




b


. When ball


20


engages trigger


60




a


, device


60


activates plunger


60




b


and plunger


60




b


propels ball


20


longitudinally along the length of gutter


44


back past discharge site


46


and onto a gutter outlet


44




c


. In this particular embodiment, return gutter outlet


44




c


is a simple open-ended structure with no side-kick feature. As will be shown hereafter, however, such a side-kick feature may be used if desired.




Reverse slope section


44




b


has a concave floor


44




d


guiding balls


20


along a straight path directly toward kick-back device


60


. In the particular embodiment shown, floor


44




d


is curvilinear in cross-section. A variety of floor


44




d


shapes, however, would establish a consistent path of approach back toward the kick-back device


60


. Thus, for example, a V-shaped floor would carry ball


20


along a consistent path back into kickback device


60


, but a flat or convex floor


44




d


shape would not carry ball


20


along a consistent path back into kick-back device


60


. In any case, the geometry of the concave shape of floor


44




d


is sufficient in relation to a golf ball diameter to establish a substantially straight path for a golf ball moving along section


44




b


and toward kick-back device


60


.




Thus, any ball


20


reaching discharge site


46


from chute


40


loses substantially all its momentum at site


46


upon striking wall


44




a


. In use, ball


20


strikes wall


44




a


and rattles, i.e. rocks laterally in gutter


44


, at site


46


. At this point ball


20


has substantially no longitudinal momentum. Ball


20


then slowly begins to roll back toward kick-back device


60


, i.e., develops momentum under influence of gravity along the slope of section


44




b


, and eventually reaches kick-back device


60


. Golf ball


20


thereby develops new and controlled momentum down the reverse slope of section


44




c


and along the consistent path of travel provided by floor


44




d


into kick-back device


60


. As should be appreciated, therefore, any ball


20


dropping into hole


14


or into trench


30


arrives at kick-back device


60


with consistent momentum and along a consistent path directly into trigger


60




a


. This allows kick-back device


60


opportunity to consistently engage ball


20


and to propel ball


20


back along return gutter


44


toward outlet


44




c


with consistent momentum. As a result, any ball


20


exiting return gutter


44


, whether by direct outlet


44




c


or by a side-kick structure, more consistently comes to rest at a given location in putting area


16


.





FIGS. 3A and 3B

illustrate side-kick structures


44




c


′ and


44




c


″, respectively, typical of conventional side-kick devices converting ball


20


longitudinal momentum along the gutter


44


into lateral momentum onto putting area


16


. The particular geometry varies, e.g., a curved deflecting wall


70




a


(

FIG. 3A

) or angled flat deflecting wall


70




b


(FIG.


3


B), but in each case ball


20


momentum along gutter


44


is converted by deflecting the ball laterally toward and onto putting area


16


. In conventional golf putting training devices, inconsistent momentum along a return gutter results in inconsistent ball positioning in the return putting area. Under the controlled ball momentum of present invention, however, ball


20


enjoys consistent momentum along return gutter


44


and when deflected at wall


70




a


or


70




b


enjoys consistent final positioning in putting area


16


. Thus, device


10


uses a variety of alternative gutter outlets or side-kick structure geometries to consistently position a ball


20


upon return to area


16


. Thus, the present invention finds application with conventional side-kick structures converting by deflection longitudinal ball momentum into lateral momentum.




The present invention also finds application, however, as an alternative to conventional side-kick devices.

FIGS. 4-7

illustrate a side-roll device


100


as an outlet


44




c


′″ relative to golf training device


10


. Generally, side-roll device


100


absorbs the longitudinal momentum of ball


20


remaining at the proximal end of gutter. Ball


20


then rolls laterally under influence of gravity on a sloped floor out onto putting area


16


. Thus, ball


20


is not deflected directly back onto area


16


and, therefore, positioned inconsistently as a function of inconsistent delivery momentum as in the prior art. Rather, device


100


releases ball


20


from substantially zero momentum and under controlled conditions to roll back to a consistent position in area


16


. While illustrated as an outlet


44




c


′″ for use with device


10


, it will be understood that side-roll device


100


may be used with conventional golf training devices, i.e., even with those imparting inconsistent momentum along the return gutter to the putting area. For example, side-roll device


100


finds application with the training device of U.S. Pat. No. 5,102,141 as a substitute for the side-kick device thereof.




In

FIGS. 4-7

, device


100


includes an upward sloped approach


102


as the proximal end of gutter


44


. Thus, ball


20


must have sufficient momentum along the return gutter


44


to overcome the slope of approach


102


, e.g., a kick-back device must impart sufficient momentum to climb approach


102


at the proximal end of gutter


44


. While varieties of particular configurations are possible, a 5-degree slope for approach


102


has proven successful. Approach


102


terminates at lip


102




a


, i.e., a slight drop into a box


104


. Lip


102




a


prevents ball


20


from re-entering gutter


44


and falling back down approach


102


. Approach


102


delivers ball


20


into box


104


. Ball


20


continues longitudinal travel across box


104


and strikes deflection wall


104




a


. Wall


104




a


lies at sufficient angle to deflect ball


20


laterally away from putting area


16


and thereby absorb a substantial portion of longitudinal momentum of ball


20


.




As ball


20


continues to bounce about in box


104


, substantially all of the delivery momentum, i.e., longitudinal momentum as present upon arrival at box


104


, is absorbed in box


104


. Thus, box


104


includes additional walls to positioned to contain and absorb the momentum of ball


20


. A second deflection wall


104




b


lies opposite wall


104




a


and at such angle to deflect ball


20


away from putting area


16


. Wall


104




c


couples wall


104




a


and wall


104




c


and lies along a substantially longitudinal line. A third deflection wall


104




d


, also positioned to deflect ball


20


away from putting area


16


, lies at the junction between approach


102


and box


104


. To further absorb the momentum of ball


20


, a bumper


110


, e.g., a strip of self-adhesive foam rubber, lies about the walls


104




a


-


104




d


of box


104


.




Again, a variety of particular geometries are possible, but in the particular example illustrated herein wall


140




a


lies at approximately 20 degrees relative to a lateral line, wall


104




b


at approximately 25 degrees relative to a lateral line,


104




c


at approximately 90 degrees to a lateral line, and wall


104




d


at approximately 15 degrees to a longitudinal line. In any case, the walls of box


104


are positioned to absorb the delivery momentum of ball


20


upon reaching box


104


.




Floor


104




e


of box


104


slopes down toward putting area


16


. Thus, ball


20


first loses its delivery momentum in box


104


and then generates new and controlled momentum as it rolls under influence of gravity down floor


104




e


and out and onto putting area


16


. A 7-degree slope for floor


104




e


has proven successful, but variations in slope are within the scope of the present invention. In this manner ball


20


is carried a consistent distance from side-roll device


100


. Providing a concave shape for floor


104




e


would also direct ball


20


along a consistent path out of box


104


and onto area


16


. However, a flat shape of floor


140




e


has proven successful. Thus, while a concave floor


44




d


is important to direct ball


20


consistently along a given path into kick-back device


60


for consistent return momentum, side-roll device


100


can make use of a flat floor


104




e


and still acceptably, i.e. sufficiently consistently, return ball


20


to putting area


16


.




In the alternative, a one-way gate, e.g. flap structure, serves a similar purpose as lip


102


. For example, in

FIGS. 8 and 9

a modified box


104


′ is shown with a one-way gate


102




a


′ replacing lip


102




a


as a mechanism to prevent ball


20


from re-entering gutter


44


and rolling down approach


102


. In this particular example of the present invention, wall


104




a


′ lies normal to the longitudinal path of ball


20


as ball


20


enters box


104


′. Gate


102




a


′ comprises a flap panel


120


pivoting as indicated at reference numeral


122


about axis


124


and allowing ball


20


to pass from gutter


44


into box


104


′. A stop


126


prevents, however, panel


120


from pivoting back past a vertical position and into gutter


44


. Panel


102




a


′ thereby presents an obstacle to a ball bouncing off wall


104




a


′ of box


104


′. Thus, a ball


20


entering gate


102




a


′ cannot thereafter re-enter gutter


44


and roll back down approach


102


. In this particular embodiment, walls


104




a


′,


104




b


′,


104




c


′ and


104




d


of box


104


′ are generally rectangular. As with box


104


, floor


104




e


′ slopes downward toward putting area


16


. A ball entering box


104


′ passes through gate


102




a


′ and strikes wall


104




a


′ losing most of its longitudinal momentum as it bounces between wall


104




a


′ and panel


102




a


′. Eventually, ball


20


loses all its longitudinal momentum and rolls down floor


104




e


′ and out onto putting area


16


with controlled, i.e., consistent, momentum and final resting position.




It will be appreciated that the present invention is not restricted to the particular embodiment that has been described and illustrated, and that variations may be made therein without departing from the scope of the invention as found in the appended claims and equivalents thereof.
