Description

FIELD OF THE INVENTION

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

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.
1. put a laser toss assist on a tossing arm.
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.
3. see a laser spot on a middle or marked point of a ball in a lower arm position.
4. toss a ball keeping a laser spot all time on a same place.
5. ketch a ball and repeat
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

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.
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
service lines and along the top of the net to detect fault and let services respectively.
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.
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.
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
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.
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.
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
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.
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.
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
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.
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.
