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.
