Description
FIELD OF INVENTION
[0001] This invention relates generally to a system for helping a
golfer to achieve proper swing mechanics for consistently and
predictably hitting a golf ball, and specifically to a multiple
light beam device used in conjunction with an alignment and
calibration guide that provides instant and continuous feedback
before, during, and after a golf club swing, for the purpose of
hitting a golf ball in a desired direction with desired strength to
achieve a consistent and predictable direction and distance.
BACKGROUND OF INVENTION
[0002] Unless otherwise indicated herein, the materials described
in this section are not prior art to the claims in this application
and are not admitted to be prior art by inclusion in this
section.
[0003] The game of golf requires a golfer to hit a golf ball as few
times as possible with the goal of launching it from the tee
ground, on to the putting green, and ultimately into the hole on
the green. In order to do this effectively, the golfer must swing a
golf club (and on the putting green a putter must be used) in a
manner that projects the ball in the desired direction and with the
desired distance. Golf instructors and golf instructional books all
advise various techniques to teach golfers to swing their club (and
the putter in the case of shots on the putting green) in a
repeatable and consistent manner that projects the ball in the
desired direction with the desired distance.
[0004] Numerous devices are known that attempt to assist a golfer
in improving their alignment for addressing the golf ball. Such
devices include visual aids that attach to the face of the golf
club or to the shaft of the golf club. Each of the known devices is
limited to providing directional information to a golfer before the
swing takes place, but not effectively during the swing process.
Further, the known prior art addresses only the directional aspect
of the golf ball movement and not the travel distance aspect of the
golf ball movement. Proper alignment of the golf club (or putter)
to the golf ball, the alignment path of the golf club during the
golf stroke through the impact point, and the length and force of a
golfer's stroke will determine the direction and travel distance of
a golf ball. Golfers practice swing techniques taught to them by
golf instructors and golf instructional books and try to execute
proper swings in a repeatable and consistent manner.
[0005] The applicant is unaware of a teaching aid that provides
instant and continuous feedback to a golfer for the purposes of
hitting a golf ball in a desired direction and a consistent and
predictable distance. The result of this type of feedback will
allow a golfer to make immediate adjustments to foot position, body
position, club position, and golf club swing length to consistently
project the ball in the desired direction with the desired
distance.
SUMMARY OF THE INVENTION
[0006] In one aspect a multiple light beam system for alignment and
distance calibration of a golf swing is provided. The system
comprises a housing with a power source and at least two adjustable
nozzles projecting from the housing. Each of the nozzles has a
first end connected to the housing and a second end. The first end
of the nozzles can rotate within the housing to adjust the position
of each of the nozzles in relation to the housing. A light source
in communication with the power source is provided to produce at
least two light beams. A beam alignment system position in front of
the light source is configured to direct the at least two light
beams produced by the light source in the respective nozzles. The
beam alignment system is configured to generate a target line and a
distance calibration mark. The system further comprises an
alignment and calibration guide that has a body with a top flat
surface adapted to be placed on a ground. The alignment and
calibration system comprises a light reflective central line formed
centrally at the top surface along a longitudinal axis of the body
and a middle mark formed at a pre-set position on the central line.
During a training swing the target line is aligned with the central
line of the alignment and calibration guide while the distance
calibration mark is at a pre-set distance from the middle mark.
[0007] In another aspect an alignment and calibration guide is
provided. The alignment and calibration guide comprises a body
having a top flat surface and a bottom flat surface adapted to be
laid down on a ground. A central line is formed centrally along a
longitudinal axis of the body and a middle mark formed at a pre-set
position at the central line. The central line is configured to
reflect light when a light beam impinges upon it while the rest of
the top surface is configured to at least partially absorb a light.
The top surface further comprises a gloss varnish coating.
[0008] In yet another aspect a method for aligning and distance
calibration of a golf swing is provided. The method comprises align
the feet to be parallel to a projected target line, align the
projected target line along a central line of an alignment and
calibration guide, swing a golf club within a critical hitting zone
of the alignment and calibration guide to check that a position of
the golf club is being square to a swing path in the critical
hitting zone, swing the golf club until a length of a backstroke is
the same as a length of a through stroke, position a distance
calibrating beam at a pre-set position in front of a middle mark of
the alignment and calibration guide, swing the golf club back until
the distance calibration beam aligns with the middle mark, position
and hit a golf ball using a distance calibration parameters, and
record a distance the ball travels using said distance calibration
parameters in a data log.
[0009] In addition to the aspects and embodiments described above,
further aspects and embodiments will become apparent by reference
to the drawings and study of the following detailed
description.

DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS
[0018] A multiple light beam projecting device 100 is disclosed
that is attached to a shaft of a golf club to provide instant and
continuous feedback to the user before, during, and after a golf
club swing. The device can project multiple light beams onto a
hitting surface on the ground where the golf ball is located. For
example, the device 100 can project two light beams such as, two
line projections, or a line projection and a spot/point projection.
For example, one line projection can correspond to an intended
target line of the ball's path and the other line projection or the
spot projection can be used for calibrating distance of a
backstroke and thus ball travel. Other embodiments can project more
or fewer of two light beams, e.g. more or fewer of two line or spot
projections without departing from the scope of the invention.
[0019] Referring to FIG. 1, the multiple light beam projecting
device 100 is provided comprising a housing 300, a plurality of
adjustable nozzles 14 projecting from the housing 300 and a
fastening means 301 to detachably connect the housing 300 to a golf
club shaft 402 (see FIG. 2). FIG. 1 illustrates two nozzles 14a and
14b however, fewer or more nozzles can be provided without
departing from the scope of the invention. The nozzles 14a, 14b
have a first end 24 rotatably connected to the housing 300 and a
second end 25. The housing 300 illustrated in FIG. 1 is a
rectangular but it could be shaped in any other suitable form or
shape adapted to be easily mounted on the golf club. The housing
can be made of a plastic material or any other suitable light
weighted material so that it does not add much weight to the golf
club.
[0020] One or more light sources 15 can be provided to generate at
least two light beams. One of the at least two light beams can be
directed through the nozzle 14a while the other light beam can be
directed through the nozzle 14b. For example the one or more light
sources 15 can be lasers, light emitting diodes LED or any other
suitable light source. The light sources 15 are configured to emit
one or more light beams within a visible spectrum. In one
implementation, one light source can be disposed at least partially
within each of the nozzles 14 in proximity to the second end 25.
For example, FIG. 1 illustrates two light sources 15a and 15b
disposed at least partially within the respective nozzles 14a and
14b. The light sources 15a and 15b can be a laser, such as a laser
diode emitting a very narrow coherent low-powered laser beam of
visible light. The lasers 15a and 15b might be blue, green or red
laser diodes. For example, the light source 15 can be a blue laser
with a transmission wavelength of between about 400-500 nm, or
green laser with a transmission wavelength of between about 500-600
nm, or a red laser with a transmission wavelength of between about
600-700 nm. In one implementation one of the lasers, e.g. laser 15a
can be a green laser while the laser 15b can be a red laser. Any
other combination of lasers can be used without departing from the
scope of the invention. In another implementation, fewer or more
than two nozzles 14 that include at least one light source 15 can
be used to provide fewer or more than two light beams.
[0021] The device 100 can further comprise one or more beam
alignment devices 17 mounted in front the light source 15 to direct
the light beams generated by the light source 15 in the desired
direction. In one implementation, the beam alignment devices 17 can
be optical lens systems 17a and 17b mounted in front of the
respective light sources 15a and 15b in the path of the light beams
generated by the light sources 15a and 15b. The light beams
produced by the light sources 15a and 15b can be transmitted and/or
refracted by the lens systems 17a and 17b to create light line
projections 200 (see FIG. 3). The light line projections 200 can be
projected to a ground (e.g. golfing area) and can be visible to the
naked eye even in daylight. For example, the optical lens systems
17a and 17b can comprise side by side clusters of lenses.
Additionally or alternatively, the optical lens systems 17a and/or
17b can comprise beam splitter, mirror, apertures (e.g. for spot
point line projections), slits, prisms, filters or any other
suitable optical element. The optical lens systems 17a and/or 17b
can be mounted mechanically at the second end 25 of the nozzles
14a, 14b or can be attached directly to the light source 15a, 15b
in the path of the generated light beams. Person skilled in the art
would understand that the device 100 can comprise one light source
15 configured to produce multiple beams without departing from the
scope of the invention. For example, the light source can be
disposed within the housing 300. The light source 15 can be
configured to produce a light beam within the visible spectrum.
Such light beam can pass through a beam splitter and/or multiple
filters to produce at least two light beams which can be directed
through the nozzles 14a and 14b.
[0022] The device 100 can further comprise one or more switches 12
in communication with the light source 15. The switches 12 can be
configured as "on/off" switches to turn on and off the light source
15. FIG. 1 illustrates two switches 12a and 12b in communication
with the respective light sources 15a and 15b. The switches 12a and
12b can be manually operated by the user. In one embodiment only
one switch 12 can be adapted to switch at the same time both light
sources 15a and 15b. In some implementations, the switches 12a, 12b
can be configured to provide intermittent operations of the light
sources 15a, 15b, such as for example repeating on-off cycles of
varying durations for power saving.
[0023] FIG. 2 shows the multiple light beam device 100 attached to
the shaft 402 of a golf club. In the illustrated example, the
fastener 301 includes a clamp and bolt assembly to easily mount the
housing 300 on the golf club. Any other fastener or combination of
fasteners can be used to attach and/or detach the device 100 when
not in use. The fastener 301 can be permanently connected to the
housing 300 by for example welding, an adhesives or any other
method for permanently attaching the fastener 301 to the housing
300. In one implementation, the fastener 301 can be detachably
connected to the housing 300 by using for example some tongue and
groove type fasteners. The housing 300 can be positioned on the
shaft 402 so that it can face the user or can face away from the
user depending whether the user is a right handed or left handed.
Once, mounted on the shaft 402, the housing 300 can be rotated
about the shaft 402 or adjusted up and down or back and front until
it is in a position preferable by the user.
[0024] Additionally and alternatively the user may move/rotate the
nozzles 14a, 14b in relation to the housing 300 or the golf club to
adjust the position of the light beams generated by the light
source 15a/15b and to align the line projections in the desired
position/direction. For example, the nozzles 14 can comprise a
plurality of bearings or any other mechanism to allow the nozzle 14
to be rotated around its longitudinal axis to adjust its position
and thus the direction of the respective light beams generated by
the source 15 and the beam alignment system 17. The position of the
nozzles 14a, 14b can be adjusted manually by the user or can be
controlled and driven electronically. For example, one or more
joystick like buttons can be provided that are in communication
with a controller and a driver to adjust the position of each of
the nozzles 14.
[0025] In one mode of operation, the user can press the buttons of
the on/off switches 12a and 12b to energize the lasers 15a and 15b.
FIG. 3 schematically illustrates an example of the electrical and
the mechanical components housed within the housing 300. A power
source 10 provides an electrical energy to the light sources 15a
and 15b. The power source 10 can include one or more batteries. The
adjustable nozzles 14a and 14b extend from the housing 300 and
include the laser light sources 15a and 15b, which are connected to
the optical lens systems 17a and 17b as stated herein before in
connection with the description of FIG. 1. A positive terminal of a
power source 10 is connected by way of conducting lines 11a and 11b
to one terminal of the respective time on/off switches 12a and 12b.
The other terminal of the switches 12a and 12b are connected by way
of conducting lines 13a and 13b to a positive terminal of laser
light sources 15a and 15b. A negative terminal of the power source
10 is connected by way of conducting lines 16a and 16b that are
passing through the adjustable nozzles 14a and 14b to negative
terminals of the laser light sources 15a and 15b. The housing 300
encloses the power source 10 and the conducting lines 13a, 13b, 16a
and 16b and protects them from damage when adjustable nozzles 14a
and 14b are re-positioned. FIG. 3 further illustrates the light
projection lines 200a and 200b generated and projected by the
respective light sources 15a, 15b and beam alignment systems 17a,
17b. In some implementations, the housing 300 can further comprise
a control circuit to control the timing of the switches 12 and/or
position/alignment of the nozzles 14, light sources 15 and the beam
alignment systems 17.
[0026] FIG. 4 shows one example of the general layout of the light
line projections 200. In the illustrated example there are two
light beams 200a and 200b projected from the respective nozzles
14a, 14b generating target lines 201a and 201b used to indicate the
desired travel path of the golf ball. The example of the target
lines 201a and 201b illustrated in FIGS. 3 and 4 comprises
measurement markings 202, 203 and 204 that can be formed by the
optical lens system 17. The light beam produced by the light
sources 15a and 15b can be refracted by the lens systems 17a and
17b to create line projections with measurement markings 202, 203
and 204. Center-marks 203a and 203b can be situated in the middle
of the target-lines 201a and 201b. Front-measure-marks 202a and
202b can be situated in front of center-marks 203a and 203b on
target-lines 201a and 201b, and rear-measure-marks 204a and 204b
can be situated in the rear of center-marks 203a and 203b on
target- lines 201a and 201b. The front marks 202 and the rear mark
204 can be positioned at substantially the same distance from the
center mark 203. Each of the measuring marks 202, 203 and 204 can
be used for distance calibration purposes. Thus, the target lines
201 with the measurement markings 202, 203, 204 on them give visual
indications as to the golfer's alignment position to the golf ball
and provide swing length calibration (distance calibration)
information to the golfer. In one implementation, one of the line
projections 201 can be used as a target line while the other can be
used for distance calibration (i.e. its length can be used for
swing length calibration. The light line projections on the ground
may be rotated, and the golfer can adjust them so as to align the
club strike face perpendicular to the desired travel direction of
the golf ball. These visual aids assist the golfer to align his
feet, body, and golf club to the correct position in order to
execute a proper golf stroke.
[0027] In one implementation, the measurement markings can be
omitted from the target lines 201, and target lines 201 with no
markings can be projected on the ground. One of the light
projections 200 can be a spot/point beam. In one embodiment such
spot light beam can be a different color from the other line
projection. For example, the spot beam can be red color while the
line projection can be green color. Thus the green line can be the
target line 201 while the red spot can be distance calibration
beam. The position of the green target line 201 and the red spot
beam can be adjusted by repositioning of the nozzles 14. This can
allow the user to see a clear difference in the adjustment
locations of each light source e.g. laser.
[0028] Furthermore, an alignment and calibration guide 600 shown in
FIG. 5 is provided that is laid on the ground to help the golfer
with the positioning of the lasers as he aligns his club position
in relation to the golf ball, and as he swings his club to make his
golf shot. The alignment and calibration guide 600 comprises a
clearly marked middle mark 603 and a marked critical hitting zone
area 604. For example, the critical hitting zone area 604 can be
approximately 4-inches behind and 4-inches in front of the middle
mark 603. The user can use this as a visual aid to see the
rotational and rectilinear motion of the light beams as he/she
swings the golf club in the critical hitting zone 604.
Additionally, the alignment and calibration guide 600 can be
approximately 4-inches wide and 40-inches long so as to give the
user a complete visual diagram for the positioning of the golf club
and the light beam projections through the full range of the golf
stroke. The primary color of the alignment and calibration guide
600 can a dark color which can absorb the light beams, such as a
black colored, with a relatively more reflective, a lighter-colored
(such as white) center line 606. The center line 606 can be, for
example approximately 1/4 inch wide and can run down the entire
length of the alignment and calibration guide 600. The target line
201 can be strongly absorbed by the dark colors and won't be nearly
as visible as when it is projected onto the light color of the
central line 606. When the user swings the golf club with the
multiple light beam projecting device 100, it becomes clearly
apparent when the target line and the distance calibration beam are
on top of the white center line 606 because they become very bright
and noticeable. Conversely, when the light projections (e.g. target
line, distance calibration beam) are not on top of the center line
606, rather they are on the black area of the alignment and
calibration guide 600, they become absorbed into the black color
and are not very bright or noticeable.
[0029] In one implementation, the alignment and calibration guide
600 can be made of a cloth or paper material that has a gloss
varnish coating on it in order to enhance the visibility of the
light beams. For example, when the target line 201 is projected
down upon the gloss varnish coating of the alignment and
calibration guide 600, its luminance is enhanced due to the
reflective properties of the gloss varnish coating and becomes
easily visible. This is an important feature because it allows
users to practice with the multiple light beam projecting device
100 at any time of night or day, indoors or outdoors. The instant
and continuous feedback the user gets by observing the target line
201 on the alignment and calibration guide 600 allow him/her to
understand the precise shape of his/her stroke and to make any
necessary modifications for improvement. The user can use this
instant and continuous feedback to adjust his/her golf swing to
keep the target line 201 in line with the center line 606 of the
alignment and calibration guide 600 for as long as possible in
order to groove a consistent and repeatable golf swing.
[0030] Additionally, the alignment and calibration guide 600 can be
marked like a tape measure along its 40-inch long length with the
middle mark 603 being the zero measurement mark (see FIG. 5). For
example, the alignment and calibration guide 600 can have
approximately 20 inches of measurement marks 608a going to the left
direction and 20 inches of measurement marks 608b going to the
right direction from the middle mark 603. In one embodiment, the
measurement marks 608 can be in metric units. In another embodiment
the alignment and calibration guide 600 can comprise two sets of
measurements marks 608, one set in inches and one in metrics. The
measurement marks 608a, 608b are used by the user to adjust the
light beams to be at exact distances from the middle mark 603 of
the alignment and calibration guide 600. When the user swings the
golf club he/she can observe the position of the target line 201 in
relation to the measurement marks 608. Thus, the user can be able
to find out exactly how far he/she has swung the club back behind
the ball, and exactly how far he/she has swung the club past the
ball. The user can then record exactly how far he has hit the golf
ball (record the distance), and can correlate this information
about the distance with the observation of the exact length of
his/her backstroke. The user can practice swinging the club at an
exact backstroke length and hitting the golf balls the same exact
distance so that his/her shots become consistent and repeatable. To
further the skills, the user can then re-adjust the light beams to
be at a different distance from the middle mark 603 of the
alignment and calibration guide 600 which will result in a
different backstroke length and a different distance. The user can
thus record the results of the new "backstroke-to-distance" pairs
and can practice until he/she becomes more skilled in hitting golf
balls at a consistent and predictable distance. The measurement
markings 202, 203, 204 of the target line projections 201 and marks
608 and the alignment and calibration guide 600 provide the user
with exact calibration of the length of both the backstroke and the
through stroke of the golf swing. The user can easily confirm that
the backstroke and the through stroke are the same distance by
simply looking at the measurement markings of the target projection
201 or alignment and calibration guide 600. This is particularly
important when using a putter, and is said to be a balanced stroke.
Additionally, by adjusting the length of the backstroke and the
through stroke of the golf swing (particularly when using a
putter), by looking at the measurement markings of the target line
projection 201 and the alignment and calibration guide 600, the
user can calibrate precisely how far he/she will hit the golf ball.
This provides the user with an unprecedented aid in distance
control (particularly when using a putter).
[0031] FIG. 6 illustrates one possible use of the multiple light
beam device 100 and the alignment and calibration guide 600. The
device 100 is attached to the golf club shaft 402 and the
adjustable nozzles 14a and 14b, the light sources 15a and 15b, and
the optical lens systems 17a and 17b are aligned with the
longitudinal axis of the golf club shaft 402. The adjustable
nozzles 14a and 14b are adjusted to allow the light sources 15a and
15b with optical lens system 17a and 17b to superimpose the line
projections 200a and 200b on the golf ball 503 as it sits on the
alignment and calibration guide 600. Further, the adjustable
nozzles 14a and 14b can be twisted to rotate the optical lens
systems 17a and 17b and the light sources 15a and 15b to position
the center-marks 203a and 203b of the target lines 201a and 201b to
align with the middle mark 603 of the alignment and calibration
guide 600. The target-lines 201a and 201b are aligned to run
straight down the center line 606 of the alignment and calibration
guide 600 and the desired travel path 502 of the golf ball 503. A
golfer 500 can arrange his/her feet in a preferential alignment in
order to strike the golf ball 503. He/she can observe and adjust
his/her feet in relation to front measure marks 202a and 202b,
center marks 203a and 203b, and rear measure marks 204a and 204b of
target lines 201a and 20 lb. In one implementation, the user 500
can adjust his/her position using the alignment and calibration
guide 600 as a reference point (to preferential distance from the
alignment and calibration guide 600), so that he/she can easily
remember and repeat the foot position alignment at future practice
sessions. The user 500 can grip the golf club shaft 402, adjust the
shoulder, hips, and legs to place the strike face of the golf club
head 505 perpendicular to target-lines 201a and 201b and in
alignment with the center marks 203a and 203b and the alignment and
calibration guide 600. Thereafter, the user 500 can fix a line of
sight 501 on the golf ball 503 and thus complete a pre-shot
alignment. Once the user 500 aligns his/her position and aligns the
target line 201 along the center line 606 of the alignment and
calibration guide 600, he/she can start his/her golf swing by
moving the golf club shaft 402 back behind the golf ball 503. By
observing the position of the front measure marks 202a and 202b in
relation to the golf ball 503 and in relation to the alignment and
calibration guide 600, the golfer can determine the exact length of
his backstroke. The golfer 500 will then proceed to swing the
striking face of the golf club head 505 so that it strikes the golf
ball 503. The golfer 500 will plainly see the visual path of the
target-lines 201a and 201b on the alignment and calibration guide
600 as the golf club head 505 strikes the golf ball 503. Further,
by observing the position of the rear-measure-mark 204 on the
alignment and calibration guide 600 in relation to the starting
position of the golf ball 503, the golfer can see the exact length
of his through stroke. Through a process of trial and repetition,
the golfer 500 will systematically build up personal data on how
far he/she moves the golf club shaft 402, and correspondingly the
front-measure-marks 202a and 202b in relation to the alignment and
calibration guide 600 and the golf ball 503, so that the length of
the backstroke can result in a predictable and consistent distance
of the golf ball 503 upon being struck by the golf club head 505.
Similarly, through this process of trial and repetition, the golfer
500 can systematically build up personal data on the motion of the
visual path of target-lines 201a and 201b on the alignment and
calibration guide 600 as the golf club head 505 strikes the golf
ball, so that he/she can learn to strike the golf ball 503 in a
predictable and consistent direction. Additionally, through the
process of trial and repetition, the golfer 500 can systematically
build up personal data on the position of rear-measure-marks 204a
and 204b in relation to the alignment and calibration guide 600 and
the starting position of the golf ball 503, so that the golfer can
determine the exact length of his/her through stroke and thus learn
to carry out an optimum balanced stroke. The golfer 500 is thereby
aided in improving his/her golfing skills. Furthermore, by
monitoring and analyzing the path of the movement of the target
lines 201a and 201b on the alignment and calibration guide 600,
with particular attention to the critical hitting zone 604 and the
center line 606 of the alignment and calibration guide 600, and the
swing path of the golf club head 505, the golfer 500 can learn to
swing the golf club in a consistent and predictable manner. The
golfer 500 is thereby aided in improving his/her golfing
skills.
[0032] FIG. 7 illustrates a method of light alignment system 700
and distance calibration method 702 for a golf training purposes.
At block 704, the method 700 comprises alignment of user's feet.
The alignment and calibration guide 600 is laid on the ground and
the target line 201 is aligned along the central line 606. Then,
the golf club (or putter) is pulled towards the feet keeping the
target line 201 parallel to the central line 606 to ensure that the
feet are parallel with the intended ball path. If the feet are not
in the proper position the user re-adjust the position and the
process is repeated until the feet are aligned in the desired
position. The method 700 further comprises a groove stroke step at
block 705 that includes swinging the golf club (or putter) down the
center line 606 and observing the target line 201 to make sure that
the stroke is on-line within the critical hitting zone 604. At
block 706 the method 700 comprises balance stroke by checking that
the stroke is the same length on both sides of the ball (balanced),
just like a clock pendulum looking at the target line 201 that acts
as a visual pendulum.
[0033] The distance calibration method 702 comprises a calibration
of a backstroke (block 707) by for example adjusting a red spot
light (or target line 201b) to shine at an exact backstroke
distance from the front face of the club (putter). This can be done
by for example adjusting the position of the nozzle 14b. Then the
user can practice the calibrated stroke at block 708 to get the
feel for the backstroke length by bringing the red distance spot
beam (or mark 202b) to exact point where the club (or putter) face
started (e.g. middle mark 603). The red distance mark can act as a
visual tape measure and the alignment and calibration guide can
help to check and provide feedback. At block 709 the method 702 can
include hitting the balls with the practiced calibrated stroke
length and observe the actual apex of the backstroke (the point to
where the distance mark moves to) and record the distance the ball
travel in a data log. Then, at block 710 the user can pre-set the
distance mark at different length (apex) and can mark the results
for several backstroke-to-distance pairs in the data log. By using
this method the user can develop a skill about the relationship
between the distance, pace and speed of hitting golf balls.
