Description
BACKGROUND OF THE INVENTION
This invention relates to apparatus for teaching both young and old
golf pupils as well as golfers how to swing a golf club correctly.
When properly swung and after much repetition, correct muscle
activity will gradually develop into lasting muscle memory that
stays with a golfer for a long while.
In most cases golf pupils unfortunately practice bad habits when
they try to bring the golf club down through on the same path the
club traveled on the backswing. This is a physical impossibility.
Whereas, in truth, the golfer and pupil should take the club back
along one path during the backswing, and down through the
ball-striking position along an entirely different path.
A golf pupil can observe and try to copy the swing of his favorite
golf professional, whose book on Golf is usually well illustrated
with photographs. But, soon the golf pupil comes to the realization
that he cannot swing his clubs like his favorite professional, and
so the pupil becomes discouraged. He then adds another book to his
library of golf books and he is no better off than when he first
read the golf book.
The prior art is replete with devices that are designed to teach a
golf pupil how to achieve that elusive "perfect swing," but, so far
as is known, no prior art reference has been found to be completely
satisfactory.
The intentional alignment of the face of the golf club to the ball
has long been the main obstacle to a good golf swing. It should be
realized that the face of the club head is square to the line of
intended flight of the ball for only a split second of time during
the perfect swing. Yet, most golfers and golf pupils try to keep
the face of the club square to the flight path at all times. Such
intentional effort takes away from the player and from the pupil
the fluidity of swing and body movement that is needed to properly
strike a golf ball.
The present invention, however, instills in the mind of the pupil
and the golfer a "mind's eye view" of the correct golf swing, and
it takes away from the pupil and the golfer, when my invention is
manipulated correctly, the natural inclination to "steer" the club
head along a certain, but incorrect path towards the ball.
I have found that once a golf pupil and golfer learns how to make a
proper backswing, he instinctively makes a proper downswing. Using
the apparatus and practicing the method of my invention achieves
this objective.
SUMMARY OF THE INVENTION
A golf training apparatus in accordance with one embodiment of my
invention comprises an arcuate structure that is provided with a
gripping portion for holding it as though it were a golf club. A
light is attached to the gripping portion which traces a path on
structure adjacent the golfer or pupil.
In a modification of my invention, there is a second light attached
to the arcuate structure which may be actuated by the golfer or
pupil and which traces another path on such adjacent structure.
In yet another modification of my invention, a light on the
simulated golf club lights when contact by an arcuate structure on
the club is made with a source of electrical power and when the
pupil or golfer holds the simulated golf club in the proper
position at the top of the backswing.
In yet a further modification of my invention, a light device is
removably positionable on the club shaft and is adjustable to
direct rays of light in a selected direction for specific training
purposes.
For a further understanding of my invention and for features and
advantages thereof, reference may be made to the following

DETAILED DESCRIPTION
Referring to FIG. 1, a golf training apparatus 11 in accordance
with my invention is shown held by a golf pupil at the address
position; the pupil holding the apparatus 11 by gripping a portion
13 as a simulated golf club. The gripping portion is connected to a
cross member 15 that is end-connected to a hoop-like structure 17
by means of tubular connectors 19, or in any other suitable
manner.
As may be seen from FIGS. 1 and 2, the hoop-like structure 17 and
the gripping portion 13 are each provided with a light designated
respectively 21, 23, and the light 23 is so installed in the free
end portion of the gripping portion 13 that it directs rays of
light along the axis oriented at an angle of about 45.degree. from
the axis of the gripping portion 13. The light 21 is so installed
in the hoop-like structure 17 that its rays are substantially
parallel to the rays emitted by light 23.
The gripping portion 13 is provided with two switches 25, 27 (FIG.
2) which can be and usually are actuated by the thumbs of the golf
pupil when his hands are on the gripping portion correctly.
The lights 21, 23 may be of any suitable form and the source of
power for such lights may be installed in the gripping portion 13
or in the structure 11, as desired. The switches 25, 27 are
connected to respective lights 21, 23. In some applications only
one switch may be used to control both lights, or only one light
may be used.
FIG. 3 illustrates the golf training apparatus 11 in another
operative position, at the top of the backswing. The golf pupil has
moved the training apparatus 11 from the address position of FIG. 1
to the top of the backswing in accordance with the method of my
invention.
A modification of my golf training apparatus is shown in FIG. 4
which comprises a gripping portion 31 and a shaft extension 33
connected axially thereto as well as an arcuate structure 35. The
gripping portion 31 is shown in FIG. 5 and it will be noted that it
is substantially the same as the gripping portion 13 of FIG. 1. The
gripping portion 31 has an end light 37 that is so oriented that
its rays of light shine along an axis that is disposed at an angle
of about 45.degree. from the axis of the gripping portion. The
gripping portion 31 is provided also with two switches 39, 41 which
can be and usually are actuated by the thumbs of the golf pupil
when he holds the gripping portion 31 in the proper manner.
The arcuate tubular structure 35 is adapted to be clamped onto the
shaft extension 33 by means of the sleeve 43 and the thumb screw
45, but those skilled in the art will appreciate that any other
structure that is suitable may be used, if desired.
The arcuate tubular structure 35 is provided with a light 47 that
is located about where shown, so that its rays of light are
directed along an axis that is substantially parallel to the rays
of light emitted by the light 37. As mentioned previously, the
lights 37, 47 are conventional and are operated by switches 39, 41
respectively. A suitable source of electric power for the lights
may be installed in the gripping portion 31, or in any other part
of the apparatus 29, as may be more convenient.
FIG. 4 also illustrates one form of other attachment 49 that is
secured to the shaft extension 33 by a second sleeve 51 at one end
as shown, using a thumb screw 53. Of course, the attachment 49 may
be secured in any other suitable manner, if preferred. The
attachment 49 is a simulated golf club head like that found on an
iron golf club. It may also be a wood club head.
Another form of attachment, such as a racket-like device 55 of FIG.
6, may be attached to the shaft extension 33 in place of the
attachment 49.
FIG. 7 issustrates schematically another golf training apparatus
57, as it is held by a golf pupil in the address position; the
pupil holding the apparatus 57 by the gripping portion 59 thereof.
The golf pupil would have received some previous instructions about
holding the club device 57 and how to address the ball in a proper
manner. The golf pupil wears an electrified contact 61 on his left
arm (a left handed pupil would wear the contact on his right arm,
of course) that is located at or just slightly above the elbow. The
contact 61 is held in place by an elastic band 62, or in any other
suitable manner, and a small wire 63 leads from the contact piece
61 to the gripping portion 59 in which there is a source of
electric power, such as a battery (not shown).
The apparatus 57 is fitted with an arcuate member 65 that is or may
be of metal or plastic or other suitable material. If it is made of
plastic, it should include an electric wire that connects to a
metal contact piece 67 at the free end and that connects to the
source of power in the gripping portion 59. If the arcuate member
65 is metal, it should be connected to the source of power in a
known way.
FIG. 8 shows schematically a plan view of the golf training device
57 of FIG. 7.
The free end portion of a modified arcuate member 69 in which there
is a microswitch 71 is shown in FIG. 9. The microswitch 71 is
connected electrically to the source of power in the gripping
portion 59, and is actuated upon contact with the arm, especially
the left arm, of the golf pupil in the manner described
hereinafter.
Another golf training apparatus 73 of my invention is shown
schematically in FIG. 10 as it is held by a golf pupil in the
address position. The apparatus 73 is provided with a light 75 at
the end of the gripping portion 77 which is like the light 37 shown
in FIG. 4. Along the shaft portion 79 there is a light 81 which is
oriented at an angle of about 35.degree. from a plane passing
through the shaft portion, as shown in FIG. 11.
FIG. 12 illustrates schematically another light 83 which is adapted
to be installed on a golf club shaft 85 or the like. The light 83
includes a short length of tubing 87 that may be of metal or
plastic and in the body portion there is a cut or kerf 89 having
the shape shown in FIG. 12. At the left hand end as viewed in FIG.
12, there is suitably mounted thereto a light 91. At the right hand
end, opposite the light 91, there is a source of electric power,
comprising one or more batteries 93. In a preferred embodiment, the
batteries are of the rechargeable type. Wires 95 connect the light
91 to the source of power through an on-off switch 97. A connection
99 for recharging the batteries 93 is also mounted to the body end
portion as shown in FIG. 12.
On the tubular body portion there are four indicia, marked with the
numerals 1, 2, 3, 4, and on the grip portion 101 of the club 85
there is an index mark 103; such mark being parallel to the axis of
the club shaft 85. The indicia 2, 4 are parallel to the
longitudinal axis of the tubular body portion 87, and the indicia
1, 3 are disposed along a line at an angle of about 40.degree. from
the axis of the indicia 2, 4.
A golf pupil may, during a training program under the guidance of a
teaching professional, or alone at a practice area, use any one or
several embodiments of my invention shown and described herein. In
using the golf training apparatus shown in FIGS. 1 or 4, the golf
pupil assumes the address position about which he has received
instruction previously. Then, the golf pupil simulates rotation of
the arcuate structure 17 or 35 in the direction of the arrows A and
B respectively turning the device about the left wrist as a pivot
(a left handed person would simulate rotation about his right
wrist). The arcuate structure is then rotated in its respective
plane until the wrists are fully cocked. Then the golf pupil turns
his shoulders in a substantially level plane, brings his arms back
in a swinging motion along the backswing, and turns his hips
clockwise until the arcuate structure is in the position shown in
FIG. 3. The hands and arms are at the top of the backswing and the
body is coiled to deliver full power on the downswing. The golf
pupil turns his hips counterclockwise and brings his arms and the
training device down as though he were striking a golf ball.
With the attachments 49 and 55 added to the apparatus of FIG. 4, an
advanced golf pupil experiences more nearly the sensation of
swinging a golf club correctly. Yet, the advanced pupil does not
strike a golf ball with the apparatus of FIG. 4.
The sensation that a golf pupil should experience when he makes the
downswing is best understood when the attachment of FIG. 6 is used.
The golf pupil should consider that he is hitting or is about to
hit a ball with a racket-like device, such as is used in playing
badminton.
In using the apparatus of FIG. 7, the golf pupil, wearing the arm
band as shown, assumes a correct address position holding the
apparatus as shown. Then, he simulates rotation of the arcuate
structure 65 in the same way as he rotates the arcuate structures
17 and 35, as described with respect to FIGS. 1 and 4 respectively.
At the address position, the metal end 67 or metal arcuate member
65 does not make contact with the electrified contact 61, but when
the pupil moves the golf training apparatus 57 correctly to the
proper position at the top of the backswing, the end 67 does
contact the piece 61. This completes an electrical circuit and the
light 68 lights.
If the light 68 does not light at the top of the backswing the golf
pupil knows that he is not holding the apparatus in the proper
position. He should then assume the address position and repeat the
backswing, but this time he should correct any fault so that
contact will be made and the light lights.
Naturally, golf pupils are not alike physically, even as some are
men and some are women, so each pupil must locate the arm band in
the proper place for him or her under the guidance of an
experienced teacher or professional. But, once the arm band is set
in the proper position, the gold pupil should practice until he can
bring the apparatus to the top of the backswing every time and make
contact with the electrified piece and light the light. The
backswing may then be said to be "grooved."
The apparatus of FIGS. 10 and 11 are used to show a more advanced
golf pupil whether or not he is moving the apparatus 73, which is
more nearly like a golf club, in the proper manner, both on the
backswing and on the downswing.
When using the apparatus 73, the lights 75, 81 are turned on. The
golf pupil assumes the address position and, facing a wall or other
vertical surface not too far away, and moves the apparatus along
the backswing to the top position. If he moves the apparatus
correctly, the light 81 will follow a predicted trace or path
marked on the wall or vertical surface. If the light does not
follow the trace or path, the golf pupil must start over again and
practice until he moves the apparatus correctly so that the light
follows the trace or path. Another person or an instructor can
follow the light path for him as he swings the apparatus.
Likewise, when the golf pupil moves the apparatus 73 in a proper
manner on the downswing, the light 75 will follow a preselected
path or trace on the ground or floor around the pupil's right foot.
The aforementioned person or instructor standing nearby can follow
the light path advantageously and advise the golf pupil if
correction is necessary.
The apparatus of FIG. 12 is used in four different positions for
training purposes. The device 83 is installed on a golf club or
club-like device by inserting the small diameter portion of the
shaft in the kerf 89, in the direction of the arrow A; moving the
device in the direction of the arrows B until the device is held in
position near the grip where the diameter of the shaft is large
enough to fill the rounded portion of the kerf as shown. In such
position, the indicia 1, 2, 3, 4 can be aligned in succession or
randomly with the index mark 103. The device 83 is positioned on
the club in FIG. 13 so that the indicia 1 is aligned with the index
mark 103.
When a golf pupil or more experienced golfer, who wished to improve
his swing, stands at the address position, and when he grips the
club 85 properly with the indicia No. 1 at the index mark 103, the
light 91 will project rays of light at an initial spot 105 on
adjacent wall or vertical structure 107. If the golf pupil moves
the club 85 properly on the backswing, the light rays will trace a
prescribed path 109, and the light rays at the top of the backswing
will project at terminal point 111; the rays making a loop 113 just
before they reach terminal point 111.
Thus, a golf instructor or other person can observe the path traced
by the light rays and advise the person that he has or has not: (1)
gripped the club properly; (2) addressed the ball properly; (3)
made a proper backswing; (4) reached a proper position at the top
of the backswing.
Now, let us assume that the instructor or other person wishes to
look more closely at one particular phase of the swing; say the
position of the club at the top of the backswing. To do this, the
golf pupil orients the device 83 so that indicia No. 2 is opposite
the index mark 103. The person then makes the backswing. If made
properly and if the club is held at the proper position at the top
of the backswing, the light rays will fall on the right shoulder of
the pupil, as suggested in FIG. 15. Thus, the correct position of
the club at the top of the backswing can be recognized easily. Of
course, if the rays of light do not fall on the pupil's shoulder,
the pupil is informed and he can make changes in his swing to
correct his fault.
Assume now that the instructor wishes to watch closely the start of
the backswing. The golf pupil then adjusts the device so that the
indicia No. 3 is aligned with the index mark. Then the golf pupil
assumes the address position and commences the backswing. If the
backswing is started properly, the light rays will trace a path 115
on the floor behind the right foot of the pupil, as shown in FIG.
16; the rays starting at an initial point 117, making a loop 119,
and trailing off in the direction of arrow 121.
While the foregoing describes how the device 83 may be used
effectively to look more closely at the several phases of a golf
backswing, the device may be used also very effectively to look
closely at the downswing; especially in the hitting zone.
FIG. 17 shows a path 123 traced by the light rays of the device 83
when the indicia No. 4 is aligned with the index mark and as the
golf pupil moves the club down and through the hitting area. If the
downswing is properly done, at about the mid-point of the
downswing, the light rays will start from initial point 125 of path
123, make a loop 127 around the pupil's right foot and then follow
path 123 in the direction of the arrow 129. If such path 123 is
followed, the golf pupil knows that his downswing is correct, but,
likewise, if the path 123 is not followed, the pupil knows that he
must make changes to correct his downswing.
From the foregoing description of the several embodiments of my
invention, those skilled in the art will recognize many important
features and advantages among which the following are particularly
significant:
That the apparatus and the method of use quickly instills in a golf
pupil and in a golfer as well a "mind's eye" view of the correct
golf swing. All mental control over the downswing is removed so
that there is no attempt to "steer" the club head toward the golf
ball;
That the golf pupil and the golfer alike obtain a proper picture of
the correct swing which otherwise is only an optical illusion that
he cannot ever attain from following or aping pictures in a
book;
That in swinging my apparatus in accordance with the method
described herein, a cocking of the wrists and a turning of the
shoulders and hips in the proper manner takes place
instinctively;
and
That when the golf pupil and golfer manipulate my teaching
apparatus so that one or more of the lights shine at a preselected
location or along preselected paths, the golf pupil and golfer know
that my apparatus has been used correctly. They then know that they
have swung the club or like device correctly and if repeated many
times that their swing is "grooved."
Although the invention has been described herein with a certain
degree of particularity, it is understood that the present
disclosure has been made only as an example and that the scope of
the invention is defined by what is hereinafter claimed.
