Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation-in-part application to
U.S. patent application Ser. No. 09/133,236, filed Aug. 13,
1998.
FIELD OF THE INVENTION
[0002] The present invention relates to the field of aids for
assisting a golfer in obtaining a proper swinging movement of a
golf club, and more particularly, relates to an overswinging
alerting mechanism for a golf club or golf club practice aid which
generates a visual and/or audible indicator for the purpose of
alerting the golfer to an improper swinging movement of the golf
club.
BACKGROUND OF THE INVENTION
[0003] In the past, various devices have been employed to indicate
an improper swinging movement of a golf club so that hopefully a
golfer can perfect his swing. For instance, in U.S. Pat. No.
1,549,350 to Deike issued Aug. 11, 1925, a whistle is either
secured within a recess of the golf club head (see FIG. 4 of Deike)
or extended from the top of the golf club head (see FIG. 5 of
Deike). This whistle produces the loudest sound at the point of
greatest speed of the golf club, which Deike contends should occur
at the time of contact of the golf club head with the golf ball. It
has been found, however, that the proper golf swing is not
necessarily purely dependent upon striking the golf ball at the
maximum speed of the golf club.
[0004] In U.S. Pat. No. 4,283,057 to Ragan issued Aug. 11, 1981, a
golf club is provided with an air flow hole through its head which
contains a whistle which according to Ragan provides an indication
of the smoothness and velocity of the swing based upon the
turbulence of the ambient air at the air flow hole's outlet head.
However, due to variables which determine air turbulence, such as
wind gusts, etc., it has been found desirable to provide an
overswing alerting mechanism which is not dependent upon the air
turbulence of the ambient air.
[0005] Moreover, since the whistle in Ragan is provided in an air
flow hole in the golf club head, the Ragan golf club can only be
utilized as a golf practice device unless the Ragan club head
employs a second whistle 6 which is provided in hole 12 and the
first hole 4 and whistle 5 are eliminated as is shown in FIG. 5 of
Ragan. In this embodiment, Ragan contends that sound output may be
adequate in some instances if the upper end of the shaft is left
open to provide an adequate flow of pressurized air. However, Ragan
concedes that this golf club swing trainer will only provide a
sound output that may be adequate in some instances, particularly
when the golf club is swung in the absence of excessive background
noise. However, in view of the many conditions in which golf is
played, it has been found desirable to provide an overswing
alerting mechanism which is not dependent upon the presence or
absence of background noise.
[0006] In U.S. Pat. No. 3,730,530 to Oka et al. issued May 1, 1973,
a golf swing training attachment is attached by a suction disk to
the golf club head wherein a vibration plate emits a sound when the
club head reaches a desirable speed. However, in view of the speed
of swing of the golf club, such attachments have been found to fly
off the golf club. Therefore, it has been found desirable to
provide an overswing alerting mechanism for a golf club which is
permanently mounted on or incorporated within a golf club, or which
is detachably affixed to the club so as to provide an overswing
alert without flying off the club during a swing.
[0007] In U.S. Pat. No. 3,776,556 to McLaughlin issued Dec. 4,
1973, an attachment is externally mounted on the golf club shaft
which includes a pair of differently oriented and pitched whistles
which McLaughlin contends do not emit a sound when the swing of the
golf club is perpendicular to the club face but will emit differing
sounds when there is a hook or a slice. However, the generation of
sounds from the two whistles is only dependent upon the angle of
the golf club face with respect to the intended swinging direction
of the golf club. Accordingly, the McLaughlin golf club practice
aid does not produce an audible sound merely upon the occurrence of
an overswing condition.
[0008] Moreover, the United States Golf Association ("USGA")
promulgates and administers the Rules of Golf in the United States.
It is believed that each of the golf club practice devices
mentioned above does not comply with at least one of the USGA's
rules relating to improper equipment. For instance, the USGA Rules
of Golf provide that, in general, the club must not have any
external attachments (see USGA Rules of Golf 1998-1999,
.sctn.4-1a). Therefore, it is believed that the golf club practice
aids of U.S. Pat. No. 3,730,530, U.S. Pat. No. 3,776,556 and the
aid of FIG. 6 of U.S. Pat. No. 1,549,350 do not comply with at
least this USGA Rule. In addition, the USGA Rules of Golf provide
that the club head cannot have holes therethrough as it must be
generally plain in shape (see USGA Rules of Golf 1998-1999
.sctn.4-1d and App. II, .sctn.4-1d). Therefore, it is believed the
golf club practice aids of U.S. Pat. No. 4,283,057 and the aid of
FIGS. 1-4 of U.S. Pat. No. 1,549,350 do not comply with at least
this USGA Rule. Under the USGA Rules of Golf, penalties, such as
penalty strokes, etc., result from use of improper equipment. It
has therefore been found desirable to provide an overswing alerting
mechanism for a golf club which is believed to be in compliance
with the current USGA Rules of Golf.
OBJECTS OF THE INVENTION
[0009] Therefore, it has been found desirable to provide an
overswing alerting mechanism for a golf club which avoids the
aforementioned disadvantages of the prior art.
[0010] An additional object of the present invention is to provide
a golf club with overswing alerting mechanism which generates a
visual and/or audible indicator for the purpose of alerting a
golfer to an improper swinging movement of the golf club.
[0011] Another object of the present invention is to provide an
overswing alerting mechanism which is not purely dependent upon the
speed at which the golf ball is struck by the golf club.
[0012] A further object of the present invention is to provide an
overswing alerting mechanism for a golf club which is not dependent
upon the air turbulence of the ambient air to generate an audible
sound upon the occurrence of an improper swinging condition.
[0013] Still another object of the present invention is to provide
an overswing alerting mechanism for a golf club which is reliable
in producing an audible sound upon the occurrence of an overswing
condition regardless of the presence or absence of background
noise.
[0014] An additional object of the invention is to provide an
overswing alerting mechanism for a golf club which is permanently
incorporated within the golf club or is detachably affixed to the
golf club.
[0015] A further object of the present invention is to provide a
golf club with overswing alerting mechanism which is believed to be
in compliance with the current USGA Rules of Golf.
[0016] A still further object of the present invention is to
provide a golf club with an overswing alerting mechanism which
incorporates a digital read for indicating the speed at which a
player swings the club. The indication may represent the actual
speed of some portion of the club (e.g. the club shaft), the
relative speed of a club portion from swing to swing without regard
to any actual speed, or may merely represent how hard a player is
swinging without reference to the speed of any club portion (e.g. a
representation of how fast a players arms are moving during a
swing).
[0017] Another object of the invention is to provide an overswing
alerting mechanism which is equipped for transfer of swing
information to an external memory and/or processor.
[0018] Through use of the present invention a golfer's swing speed
can be assessed and a correct swing speed for the golfer can be
determined. By swinging at the determined speed the golfer is more
likely properly execute the swing, returning the club face to the
ball square on the downswing and avoiding poor shots (e.g.
"slices", "hooks", "worm burners" and "pop ups").
[0019] Various other objects, advantages and features of the
present invention will become readily apparent from the ensuing
detailed description and the novel features will be particularly
pointed out in the appended claims.
SUMMARY OF THE INVENTION
[0020] In accordance with the present invention, a golf club with
an overswing alerting mechanism is provided which produces an
audible sound upon occurrence of an overswing condition. As is
typical, this golf club includes a golf club shaft having a hollow
opening extending therethrough and a golf club head supported on an
end of the golf club shaft with the golf club head having a
striking face for hitting the golf ball.
[0021] In accordance with one of the general objects of the present
invention, the overswing alerting mechanism disclosed herein can be
permanently incorporated within the golf club of the present
invention. More particularly, the overswing alerting mechanism of
the present invention is housed entirely within the hollow opening
of the golf club shaft. This overswing alerting mechanism includes
a sound generation assembly for generating an audible sound upon
occurrence of the overswing condition. In a preferred embodiment,
this sound generation assembly is in the form of a horn provided
within the hollow opening of the golf club shaft. The sound of the
horn can be heard through the standard opening provided in the grip
butt of the golf club grip.
[0022] In order to provide electrical energy to the sound
generation assembly, an energy generation member is electrically
connected thereto and supported within the hollow opening of the
golf club shaft. In a preferred embodiment, the energy generation
member is in the form of two 11/2 volt hearing aid batteries.
[0023] In order to activate the energy generation member only upon
the occurrence of an overswing condition, the overswing alerting
mechanism for the golf club of the present invention includes a
circuit activating or closing member provided in the hollow opening
of the golf club shaft. In one embodiment, this circuit closing
member includes a weight member which upon the occurrence of an
overswing condition closes a contact member which in turn impinges
upon a contact adjustment screw/switch to complete an electrical
circuit such that an audible sound is generated by the sound
generation assembly. More particularly, the weight member and the
contact member are positioned within the hollow opening of the golf
club shaft so that the weight member will only close the contact
member if the golf club is overswung.
[0024] In another preferred embodiment, the circuit closing member
includes an electronic transducer which is electrically connected
between the energy generation member and the sound generation
assembly. Upon sensing an overswing condition of the golf club, the
electronic transducer completes an electrical circuit such that an
audible sound is generated by the sound generation assembly.
[0025] Moreover, an LCD readout can be provided in the grip butt of
the golf club which indicates to the golfer the speed of the golf
club shaft.
[0026] Accordingly, a preferred embodiment of a golf club with
overswing alerting mechanism has been designed which is believed to
be in compliance with the current Rules of Golf of the United
States Golf Association as the overswing alerting mechanism is not
externally attached, as it is entirely housed within the hollow
opening of the golf club shaft, and in addition, the club head
remains plain in shape (i.e., with no holes therethrough).
[0027] In an alternative embodiment of the invention the overswing
alerting mechanism accommodated within a housing which is capable
of being detachably affixed to a golf club. In this manner the
mechanism may be attached to a golfer's club as a practice aid and
detached from the club when the golfer is playing a round.
[0028] Further, in a preferred embodiment of the invention the
overswing mechanism includes one or more accelerometers for the
purpose of detecting overswing conditions. The data from the
accelerometers may be processed and/or stored in a processing unit
internal to the mechanism, and may be passed from the internal
processing unit to a second processing unit, external to the
mechanism, for further processing and/or long term storage.

[0039] As is shown in FIG. 1, the overswing alerting mechanism 20
includes a sound generation assembly 22 for generating an audible
sound upon the occurrence of an overswing condition. In the
preferred embodiment, the sound generation assembly 22 is in the
form of a horn but it can be any electrically-operated device which
can emit an audible sound. As is shown in FIG. 1, the sound
generation assembly 22 is sized to fit within the hollow opening 14
of the golf club shaft 12.
[0040] In order to provide electrical energy to the sound
generation assembly 22, an energy generation member 26 is
electrically connected thereto and supported within the hollow
opening 14 of the golf club shaft 12. In the preferred embodiment,
the energy generation member 26 is in the form of two 11/2 volt
hearing aid batteries. However, any power supply which can be sized
to be accommodated within the hollow opening 14 of the golf club
shaft 12 and still provide sufficient electrical power to the sound
generation assembly 22 may be employed.
[0041] As is shown in FIG. 1, the overswing alerting mechanism 20
for a golf club of the present invention also includes a circuit
activating or closing member 30 provided in the hollow opening 14
of the golf club shaft 12 which activates the energy generation
member 26 only upon the occurrence of an overswing condition. More
particularly, this circuit closing member 30 includes a weight
member 32 which, upon the occurrence of an overswing condition,
closes a contact member 34, which in turn, contacts a contact
adjustment screw/switch 36 which is electrically connected to the
sound generation assembly 22 by means of electrical wiring 35.
Accordingly, the electrical circuit between the energy generation
member 26 and the sound generation assembly 22 is closed to thereby
generate an audible sound from the sound generation assembly 22. As
shown in FIG. 1, the weight member 32 and contact member 34 are
positioned within the hollow opening 14 of the golf club shaft 12
so that the weight member 32 will only close the contact member 34,
and thus close the electrical circuit between the energy generation
assembly 26 and the sound generation assembly 22, if the golf club
is overswung.
[0042] Another preferred embodiment of the circuit closing member
for the overswing alerting mechanism for a golf club of the present
invention is shown in FIG. 2. In this embodiment, the circuit
closing member 30a includes an electronic transducer 38 which is
electrically connected between the energy generation member 26 and
the sound generation assembly 22 by means of electrical wiring 39a
and b. Upon sensing an overswing condition of the golf club, the
electronic transducer 38 closes the electrical circuit such that an
audible sound is generated by the sound generating assembly 22.
[0043] In a further embodiment of the present invention, as is
shown in FIG. 3, an LCD readout 40 can be provided in a recess 42
of the grip butt end 23. This recess 42 extends appropriately
1/4.times.1/2 inwardly from the top end of the grip butt end 23.
The LCD readout 40 indicates in miles per hour the speed of the
golf club shaft.
[0044] An alternative embodiment of the invention is shown in FIGS.
4 and 5. As can be seen from FIG. 4, in the alternative embodiment,
the overswing alerting mechanism 20 is positioned within a housing
50 that may be generally cylindrical or conical in shape--although
it is not limited to such shapes. The housing includes two "end
surfaces" 50a and 50b, end surface 50a having a through hole 56,
and end surface 50b being fixed to a projection 52. The through
hole 56 is provided for allowing sound projected by the overswing
mechanism's sound generation unit (element 22 in FIGS. 1 and 2) to
exit the housing uninhibited. Projection 52 is provided for
detachably attaching the housing to the butt end of a golf club.
That is, the projection is inserted into a standard central opening
of a grip butt like the opening 23 and butt 25 described in
relation to FIGS. 1-3.
[0045] Further, as can be noted from FIG. 4, end surface 50b is
concave in shape in order to more securely adjoin the butt end of a
golf club, and end surface 50a includes a protective lip 54
projecting upward from the surface.
[0046] FIG. 5 shows the outside of the housing of FIG. 4 as viewed
by looking down on surface 50a. As can be seen from FIG. 5, surface
50a is generally circular in shape, and therefore lip 54 which runs
along the perimeter of the surface is also generally circular in
shape. As further shown, a display 58 and buttons 60a and 60b are
positioned within surface 50a. The lip, which projects
approximately 1/8" above surface 50a, is provided primarily to
protect display 58 and buttons 60a, 60b from direct impact with the
ground and other objects. The display is used, for example, to
display a golfer's swing speed, while the buttons may be
respectively used, for example, to turn the mechanism on and off
and to set the swing speed at which the alarm should be activated.
Some alternative uses of the display and buttons are described
below with respect to FIG. 6.
[0047] FIG. 6 is a block diagram representation of a preferred
embodiment of the alerting mechanism of the invention. The alerting
mechanism of FIG. 6 includes a multiple of sensors 68a, 68b, 70a,
70b, 72a and 72b and a processing unit 72, in addition to the
previously described power source 26, sound generation assembly 22
and display 58. A set of user controls 64 and a computer interface
are also included, the user controls referring, for example, to
buttons 60a and 60b of FIG. 5, and the computer interface being
provided for coupling of the mechanism to an external
computer/processor.
[0048] Each sensor of FIG. 6 is capable of measuring force applied
to the alerting mechanism along a particular axis. Thus, for
example, sensor 68a is an accelerometer which measures the force
applied to the mechanism along the X-axis of the three dimensional
reference system. Similarly sensors 70a and 72a may be
accelerometers which respectively measure Y-axis and Z-axis forces.
In one possible application, sensors 68a, 70a and 70b operate to
measure three-dimensional force components acting on the mechanism
during a golf swing and pass the measurements to the processing
unit which derives an indication of the swing speed from the
measurements. It should be noted, however, that the use of three
sensors is not required for generation of a swing speed indication.
Any one of the sensors 68a-72b, or any combination of the sensors
68a-72b, can be used to provide a swing speed indication. Of
course, the number of sensors which can be used is not limited to
six.
[0049] Regardless of the number of sensors employed, the data from
the sensors is processed and/or stored in the processing unit 62.
In the configuration depicted in FIG. 6, two sensors are employed
for each axis of motion and processing the data from each axis
involves a differential calculation. That is, in order to convert
axial g-forces to actual club head speed, one must employ two
sensors per axis and measure the differential g-force on the
sensors.
[0050] In any event, the data processed/stored in the processor can
be used to generate an indicator of club head speed suitable for
viewing on display 58 and/or suitable for triggering the alarm of
the sound generating assembly 22. Furthermore, the processing unit
may be coupled to a computer via computer interface 66 so that
sensor data stored in the processing unit can be downloaded to the
computer for further analysis. For example, data from sensors
68a-72b may be used by a computer to construct a graphical
representation of a golfer's entire swing.
[0051] Based upon the foregoing, it will be appreciated that the
golf club with overswing alerting mechanism of the present
invention generates an audible sound upon occurrence of an
overswing condition. Moreover, the generation of the audible sound
of the overswing alerting mechanism of the present invention is not
purely dependent upon the speed at which the golf ball is struck by
the golf club as instead an audible sound is generated if the golf
club is overswung.
[0052] Further, since the overswing alerting mechanism of the
present invention is not in the form of a whistle, it is not
dependent upon the air turbulence of the ambient air.
[0053] Moreover, it is believed that the preferred embodiments of a
golf club with overswing alerting mechanism of the present
invention set forth above comply with the current USGA Rules of
Golf relating to golf equipment. That is, in order to make the golf
club with overswing alerting mechanism of the present invention
suitable for both practice and play, the mechanism is permanently
incorporated within the golf club. In this regard, the mechanism is
not externally attached, as it is entirely housed within the hollow
opening 14 of the golf club shaft, and in addition, the club head
remains generally plain in shape (i.e., it requires no holes
through the club head). Alternatively, the overswing alerting
mechanism is accommodated within a housing that can be detachably
affixed to a golf club so that the mechanism can be attached to the
club during practice and detached during play under USGA rules.
[0054] In a further embodiment, as shown in the dotted line in FIG.
1, an on-off switch 40 can be attached to the golf club shaft 12
for activating and deactivating the overswing alerting mechanism 20
when desired.
[0055] In still another embodiment, one or more accelerometers are
included within the alerting mechanism 20, the data from these
accelerometers being used to provide overswing indication and being
downloadable to a processor and/or memory external to the
mechanism.
[0056] While the present invention has been particularly shown and
described with reference to certain preferred embodiments, it will
be readily apparent to those of ordinary skill in the art that
various changes and modifications may be made therein without
departing from the sprit and scope of the invention. It is intended
that the appended claims be interpreted as including the foregoing
as well as various other such changes and modifications.
