Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to methods and
devices used in the teaching game of tennis and more specifically
to a device and method of use for teaching tennis toss, serve, eyes
and body coordination when device on a tossing or hitting hand.
BACKGROUND OF THE INVENTION
[0002] A serve is a most important action in a game of tennis. A
contemporary player can't be successful without a big serve. Many
say a toss is 70% of a serve. Even average tennis player can make a
serve very powerful and ballistic, but mostly because of a lucky
toss. Our dream, purpose and efforts make a toss not a lucky, but
constant. The main tossing problem is a ball release. Fingers and a
palm participate in this action. A ball must be released from the
highest position of a fully extended straight arm and stay on the
same axial line till rich a hitting point. A right toss creates
forwarded body movement along with a ball direction. This movement
is a logical, natural, expected, timing managed and comfortable to
hit. Fingers must be opened very gently when a palm is a most
forwarded and protruded position. No arm and wrist rotation
prevents a tossing ball deviation from an axial line. A laser toss
assist makes a toss and serve practice effective, easy, fast and
enjoyable.
[0003] 1. put a laser toss assist on a tossing arm.
[0004] 2. a wristband colored line must be elongated with a ling
axis of an arm and be seen all time of a toss movement. Must be
established visible and imaginable straight line extended through a
hand, wrist, colored line on a wristband and a ball.
[0005] 3. see a laser spot on a middle or marked point of a ball in
a lower arm position.
[0006] 4. toss a ball keeping a laser spot all time on a same
place.
[0007] 5. ketch a ball and repeat
[0008] Practice with a laser toss assist can be at home, park,
work, when walking with a dog, watching TV and many other life
situations. A laser toss assist also can be used for practice
hitting arm coordination with eyes and body movements by quick
point a laser spot on a target. Many individual exercises can be
created.
DESCRIPTION OF THE PRIOR ART
[0009] In all possible search was not found a laser pointer device
on a wristband for practice a serve, toss, timing, coordination,
eyes control and body motion. Using a laser beam spot was found in
archery, golf, baseball, tennis court monitoring system, firearm
and not related to sport technical, electronic and medical
devices.
[0010] U.S. Pat. No. 4,00,4805 "electronic line monitoring system
for a tennis court" issued to Chen, Kun-mu in Aug. 30, 1974
describes as an optical tennis line sensing system employs a double
beam laser for projecting only a pair of collimated beams of light
along the entire outer boundary and base lines of a tennis court
with one beam positioned on the line slightly above the playing
surface and the remaining being positioned slightly outside the
lines. A detector circuit including photo multiplier light sensors
detects interruptions of the light beam in a timed sequence for
generating a signal indicating when a tennis ball is out of bounds.
The detector circuit discriminates between momentary interruption
of one of the light beams by a tennis ball and interruption of one
or both of the light beams by the player's foot. Display means
coupled to the detector circuit displays only out-of-bounds shots
which are marginal and which cannot be accurately called by the
line judges. A laser beam and photomultiplier and associated
detection and display circuit are also employed at the
[0011] service lines and along the top of the net to detect fault
and let services respectively.
[0012] U.S. Pat. No. 4,894,528 "laser beam lawn tennis net referee"
issued to Diaconn, Sever on Jan. 16, 1990 describes as a low
intensity laser oscillators produce precisely located beams on each
side of the net detected by laser receivers on the opposite end of
the net along with appropriate electronics to monitor and announce
each time that the served balls intercept the beams and cause the
laser beams to not be detected by the appropriate receiver.
[0013] U.S. Pat. No. 5,692,965 "golf suing training device with
laser" issued to Nigham Jr, William on Dec. 13, 1995 describes a
golf swing training device includes a golf club including a head
coupled to a shaft. At least one laser device detachably coupled to
the shaft of the golf club and produces at least one laser beam. A
power source is coupled to the laser device. An attachment
mechanism detachably secures the laser device to the golf club
shaft in a manner such that the laser beam provides a feedback
signal to the golfer that is indicative of a position and a motion
of the head during the top of a backswing of the golf club by the
golfer.
[0014] U.S. Pat. No. 6,216,381 "laser device for use in adjusting a
firearm's sight and a method for aligning a laser" issued to Srand,
Jan on May 24, 1999 describes a device facilitates adjustment of a
sight of
[0015] a firearm by providing a visible mark on a target when the
device is placed within a chamber of the firearm. The device may
include a laser module energize able within the chamber to produce
the mark at a position along a laser axis, a power supply situated
within the chamber to energize the laser module when an
electrically conductive flow path is completed with the laser
module, and an electrical circuit including a conductive part of
the firearm through which electrical current flows to complete the
flow path. A method of laser module alignment is also demonstrated
involving rotation of and limited linear motion of the laser
module.
[0016] U.S. Pat. No. 6,605,005 "detachable laser pointer for golf
putter" issued to Lin, Tony on Jul. 19, 2002 describes a detachable
laser pointer is constructed to include a mounting base, the
mounting base having a smoothly arched rear coupling groove for
coupling to the shaft of a golf putter and a locating plate of
C-shaped cross section upwardly extended from the smoothly arched
coupling groove for plugging in between the shaft and grip of the
golf putter and a front receiving groove, a joint rotatably coupled
to the receiving groove, a laser module pivoted to the joint and
adapted for emitting a laser beam to aim the putter head of the
golf putter to the hole.
[0017] U.S. Pat. No. 6,742,2996 "laser device for use in adjusting
a firearm's sight" issued to Strand, Jan on Feb. 14, 2001
describes
[0018] a device facilitates adjustment of a sight on each of a
variety of firearms having different calibers by providing a
visible mark on a target when the device is placed within a chamber
of any of the firearms. The device includes housing, and a laser
module energiziable within the housing to produce the mark at a
position along a laser axis extending through the firearm's barrel.
An outer sleeve fits snugly around at least a portion of the
housing, and has an external shape sized to fit snugly within a
chamber of predetermined caliber for one of the firearms. A power
supply situated either within the housing or within the sleeve
electrically energizes the laser module.
[0019] U.S. Pat. No. 6,770,002 "laser bat" issued to Aigotti,
Christine on Apr. 4, 2002 describes as a bat, constructed generally
of the shape, weight and material usually used and formed for the
batter is provided so as to have a small diameter stream of light
extended through the central axis from one end to the other. The
formation of the light stream emitting out the knob end of the bat
will allow the batter to correctly align the knob of the bat with
the ball during the initial movement of a swing. The batter and
his/her coach will then be able to determine if there are errors in
the player's angular position of the bat relative to the ball.
[0020] U.S. Pat. No. 6,796,038 "range adjustable laser sight for
archery" issued to Humphries, Lee Nelson on Dec. 17, 2002 describes
an environmentally sealed, self-contained, adjustable beam laser
sight stabilizer combination for use in archery. The laser sighting
device of present invention is comprised of a single cylindrical
compartment housing a power source, a laser module coupled to the
power source and having a laser diode for emitting laser beams, a
cam operated laser module elevating mechanism and an inner
cylindrical body. The cylinder has a front face and laser light
exit formed at the center of the face and aligned with the laser
diode. The outer cylinder is rotated axially about the inner body
and acting ob the laser positioning cam. The cam converts rotary
motion into a linear position change acting on the face of the
laser module producing an angular displacement about its pivoting
axis resulting in a change of vertical divergence of the laser beam
with respect to the bow. A user calibrated waterproof self-adhesive
range scale is installed on the moving cylinder adjacent to a
stationary base. The laser sight further incorporates an external
adjuster module connected co-axially to the cylinder rear face by a
pivoting screw. The adjusting module face contains an annular of
set screws axially aligned with the cylinder's rear face. Alternate
screw force applied at the rear cylinder face changes the
horizontal and vertical angle of laser beam departure from the bow
providing a true zero point adjustment. The adjuster
[0021] module also attaches the laser sight/stabilizer to the bow's
stabilizer bushing and provides vertical tracking alignment of the
laser beam range adjustment with respect to the bow. Additionally
the laser is activated by a hermetically sealed, magnetically
controlled switch and adjustable finger ring magnet
combination.
[0022] U.S. Pat. No. 7,381,140 "tennis teaching instructional aid"
issued to Stanisic, David on Dec. 6, 2006 describes as a training
device to improve tennis skills. The device includes wristbands for
encircling each wrist of a user and a tension device with an
umbilical attached to it and to the wristbands. The umbilical is
under constant tension during use of the training device to
encourage the movement of a user's hands in unison in carrying out
a tennis stroke.

[0037] 2. A wristband colored line 18, FIG. 3
[0038] 3. A flexible plastic tube 6, FIG. 1
[0039] 4. A laser pointer device 7, FIG. 1
[0040] 1. A wristband used for laser toss assist has no specific
characteristics. Can be any comfortable size, color and shape. A
better color is a subdued color making sharp distinguish between a
wristband and wristband colored line. A color of a choice is a
green, blue, black or white. A color of a line is a yellow or
red.
[0041] 2. A wristband colored line is a yellow or red line on a
back surface of a wristband extended from a lower 21, FIG. 2 to an
upper border 22, FIG. 2 straight under a middle of a palm base. The
purpose of a colored line is to create visible and imaginable
straight axial line through a tossing hand, wrist, colored line and
a ball.
[0042] 3. A flexible plastic tube connected by a plastic strips 5,
FIG. 1 to an inner back side of a wristband, straight under a
wristband colored line. A size and shape of a flexible plastic tube
corresponds a size and shape of a laser pointer device and makes
possible to move it forward and back. A flexible plastic tube has
an opening hole for push on/of button of a laser pointer device and
makes it to be in "of" position when a laser pointer device is a
fully inside of a flexible plastic tube. A opening hole depends on
a model of a laser pointer device. When a laser pointer device
pulled out from a flexible plastic tube for a working position a
push button of a laser pointer

in "on" position. After this action can be seen a laser spot. A
laser pointer device switched "of" by pushing back, inside a
flexible plastic tube till a push button rich an opening hole. A
laser pointer device pulled out from a flexible plastic tube around
10 mm and control a protruded and forwarded position of a palm with
a ball. This is a classic position for a tossing action. Moving a
palm back to a straight position push a laser pointer device back
inside a flexible plastic tube to an "of" position.
