ATTORNEYS g oops SWING RAINI G APPARATUS BACKGROUND OF THE INVENTION 1. Field of the Invention --This'invention relates to the field of art of systems and methods used in analyzing and instructing golfers in their swing. I
2. Prior Art When instructing a golfer on a proper swing, a professional watches the golfer swing and then tells him to vary certain movements. By trial and error, he assists the golfer in achieving more consistent results. In this way, the professional analyzes the golfers swing though the golfer himself can not see .the mistakes he is making to assist himself.
It has been known to use various optical methods, such as close circuit television, to photograph the golfer while heis swinging. The videotapes are played back for the golfer so that he can view his actualswing. However, the golfer is merely watching himself swing and there is no criteria for him to judge the manner in which he should have swung. During the swing, there are changes in body position and his timing with these changes taking place so quickly that it is very difficult for him to analyze his mistakes.
In other prior methods, a high speed still camera is used to photograph a golfer while he swings in front of a grid. The resultant forty or more still picturesare then analyzed. However, there is stillno way for the golfer to'interpret and translate his body movements and timing to an optimum.
' SUMMARY OF THE INVENTION A system for analyzing a golfers putting stroke when he assumes a ball address stance with respect to a simulated ball or point and aims the putter at a target. A
mirror is secured to the putter and a light source shines a beam'of light parallel to a line between the target and the simulated ball. The image of the light beam is reflectedby' the mirror and is displayed on a screen havaddress stance. Golfer 11 squares himself up with respect to simulated ball 14 (called a point)-aiming at a target 12. Target 12 is approximately the size of a golf ball and is light in color and appears to the golfer as a point target. Target 12 may be approximately ten to fifteen feet from point 14. LineZl is defined as a straight line parallel to straight line 24 between point 14 and target 12.
A mirror 15 is mounted on shaft 10a of putter 10 with the square reflecting surface thereof being parallel to the club front-face 10b. The reflecting surface is preferably of substantially small area, as for example, one inch square.
A collimated source of light 20 is mounted in front of thebase of a screen 25 and behind target 12. Light I face.
It will be understood that mirror 15 may have a concave reflecting surface rather than a flat reflecting surface shown in FIG. 1. Such a concave surface may have a focal lens equal to the distance between the mirror and screen 25. In this manner, a substantially small area spot of light 28 'would be displayed on the screen for ease in viewing. Such a concave mirror (not shown) would have the advantage of not requiring as collimated a light source as required by flat reflecting surface lSa.
For example, screen 25 may be 8 feet high and 10 feet wide. A grid 30 is formed on screen 25 having x and y coordinates with the lines forming the grid both in the x and y coordinates being separated by 2 inches. The center 30a of grid 30 (F0, y=0) indicates the point at which spot 28 shines when putter l0 is in its initial address position. That is, golfer 11 is in his ball address position and mirror 15 and the putter face 10b are parallel to screen 25.
' It will be understood that with putter l0 behind ball 14, light spot 28 shines in the minus y coordinate while when putter 10 is forward of ball 14, spot 28 shines in the plus y coordinate. Spot 28 in the plus x coordinate indicates that for right handed golfer l 1, club face 10b is man open position while the minus x coordinate indicates the club face is in a closed position. On the other hand, for a'left handed golfer, the plus x coordinate in dicates club face 10b in a closed position while the minus x coordinate indicates an open face. An increasing value in the plus x coordinate indicates an increasing club face opening while a decreasing value in the plus x direction indicates a relative closing of the club 'It will be understood that fora perfect putting stroke,
In a more typical example, spot 28 may follow path 31 as shown into the fourth quadrant. Path 31 indicates for a right handed golfer an increasing open club face position until point 32 is reached which is the end of the backstroke. During the forward stroke along path 34, the club face begins closing as indicated by the decreasing value in the plus x direction. Spot 28 crossing the x axis indicates contact of the club face with ball 14 with club face being open an amount indicated by the grid scale. The remaining path indicates the follow through of putter 10 after the simulated ball is hit with the path going through the first and then into the sec- 0nd quadrant.
In the foregoing pattern indicated by paths 31 and 34, the ball will travel to the right of intended target 12 a distance that may be calibrated by the grid chart.
Another typical example of a path of spot 28 is illusforward stroke indicated by path 36, the golfer has overcompensated for his opening the face of the club by quickly closing the clubface. At the simulated point of contact on the x axis, the path of the light 'spot indicates that the club face has been actually substantially closed. Specifically, at the x axis with y= and x is some negative value indicating a closed club face. Accordingly, the simulated ball 14 would be hit-to the left of target 12'. It will be understood how the foregoing would be reversed for left handed golfers.
In order to retain or record the image of path 31, 34 in FIG. 2 and path 35, 36 in FIG. 3, a camera 40 may be used. For example, camera40 is focused on screen and the room in which the operation is taking place is dimly lit. Prior to the swing, golfer l1 actuates switch 41 to open the shutter of camera 40. At the termination of the swing, golfer 11 again actuates switch 41 to'close the shutter. By the use of a Polaroid camera, a picture may be immediately obtained. A grid formed on a I transparent material may be'placed on the developed picture to correspond with grid on screen 25. In this manner, the picture directly indicates the path of the stroke and all of the grid lines are present. This technique is particularly useful when agolfer is testing himself or is practicing his-putting stroke.
It will be understood that other methods of retaining the stroke path may be used. For example, a high light retentivity coating may be applied to screen 25.
In view of the foregoing description of the invention, other uses of the system and method will become apparent. One use is for analyzing the swing of a golfer with another person such as an instructor doing the analysis. Ari-additional use is to allow a golfer to prac tice his swing and by viewing the resultant pattern to improve his stroke. A third use is to determine the consistency in which a golfer lines up his putts.
