MULTIPLE LIGHT BEAM METHOD AND SYSTEM FOR GOLF SWING ALIGNMENT AND CALIBRATION
An improved method and system for aligning and calibrating the swing of a golf club, specifically a putter, that uses multiple laser beam projections with markings on them, used in conjunction with an alignment and calibration guide laid on the ground for providing instant and continuous feedback to a golfer for the purpose of hitting a golf ball in a straight direction with a consistent and predictable distance.
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 INVENTIONUnless 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.
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.
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.
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 INVENTIONIn 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.
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.
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.
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.
Throughout the drawings, reference numbers may be re-used to indicate correspondence between referenced elements. The drawings are provided to illustrate example embodiments described herein and are not intended to limit the scope of the disclosure. Sizes and relative positions of elements in the drawings are not necessarily drawn to scale. For example, the shapes of various elements and angles are not drawn to scale, and some of these elements are arbitrarily enlarged and positioned to improve drawing legibility.
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.
Referring to
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,
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
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.
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.
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.
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.
Furthermore, an alignment and calibration guide 600 shown in
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.
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
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.
