6 Claims, 5 Drawing Figures GOLF COMPUTER MEANS The invention relates to a golf computor that can be carried by the players containing particularly necessary scientific information for guidance and training for hitting a ball properly, having apparatus to measure headwinds and their allowances and tailwinds plus converting trajectories into useful data reference.
The present invention provides improved club selection on specific yardage on a hitting distance dial for all users which vary according to their proficiency levels. It shows the beginner, the amateur and the professional which iron or club to use and which alternate club if any, on all distances. This provides excellent data and urges the user towards higher effectiveness achieved by others using different clubs. This device is adjustable for a slow or fast couse, and it provides the club number automatically.
Science is important to golf, this is conclusive. Scientific golf ball tests are being conducted on computers at Universities, and there will be much more scientific investigation in the future on equipment and the environment they are used in.
The factors concerned in evaluating distances of a golf ball hit up to 400 yards involve the laws of physics. The path of a golf ball in the absence of the atmosphere would be a parabolic are for which there exists a simple relation, giving the range of a ball or projectile in terms of the initial speed and angle of elevation. Unfortunately for golfers, the atmosphere does exist and 300 yard drives are evidence of considerable athletic prowess. For example: with a wind of 30 miles per hour behind you, and a ball hit 200 yards normally with the wind at the ball will travel an extra 80 yards based upon a 45 normal trajectory. With the wind in front, it would lose 80 yards and only travel 120 yards. Analytically, the situation expressed in terms of yards is a matter where physics explains what really occurs to a golf ball when hit. The speed of a golf ball in flight is subsonic but above the critical value required to produce laminar flows (region of validity of Stokes Law). The effect of the air flow is dependent on a drag" coefficient and the square of the speed of the ball relative to the air. The value of the coefficient is a matter of experimental determination. Knowing the force acting upon a projectile, Newtons second law can be numerically integrated (in two dimensions) and the trajectory determined. This yields the range as the function of the initial condition of motion (speed and elevation). Introducing the wind complicates the problem because the drag force now involves the speed of the wind as well as that of the particle. This would not be too serious in a numerical integration, except that in this particular case, it makes the problem three dimensional. Factually, mortar shells are the closest ordnance equivalent in range and trajectory to golf balls although they are different in weight, size and shape. Attempts at finding mortar shell tables in artillery manuals were unsuccessful. Information tables were evaluated for individual problems involving use of computers to find the values of windage and different degrees of approach that face the GOLFER. The serious golfer having this information can perfect his game to a greater point of perfection. All of these advantages are inseparately a part of this golf that calculates windage, trajectories, selects the club, adjusts for course conditions, embodies a compass, having apparatus for improved multiple counting means.
Accordingly, a principal object of this invention is to provide new and improved GOLF COMPUTERS MEANS for golf players and teachers.
Another object of the invention is to provide new and improved golf computer means comprising, a base, four rotatably mounted discs having readouts placed symmetrically in a configuration that allows maximum indicia information to be viewed, having additional discs on the back side including apparatus for counting more than one computers strokes count, having upon it a wind direction and speed device and a level apparatus.
Another object of the invention is to provide the golfer with scientific information readily usable in his play, viewed at the symmetrically located readouts, containing valuable information on how and where to hit a ball under all circumstances.
Another object of the invention is to provide a pocket edition model or the bag type, the former fitting in ones pocket and very convenient to carry. In the case of a pocket model both sides would be utilized for the necessary indicia, eliminating on that model the counter and other apparatus on the the back.
Another object of this invention is to provide the golfer with important calculations on the prescribed arc and allowances to make that compensate for the effect of the wind upon the ball. It does not only tell you the gain or loss in yards but also the compensation factor for proper allowance to know where to hit a ball so that it reliably returns to a given spot.
Another object of the inventionis to provide mechanically operated manual dials so that such mechanical configuration facilitates the utility of this new invention needed by golfers.
These and other objects of the invention will be apparent from the following specifications and drawings of which;
FIG. 1 is a front view of an embodiment of the invention FIG. 2 is a side view of an embodiment of the invention FIG. 3 is also a side view of another embodiment of the same invention FIG. 4 is a rear view of the dials on the back FIG. 5 illustrates an example of a normal problem.
Referring to the figures the invention comprises a plastic or metal base 1, a rotating disc 2, another rotating disc 3, a rotating disc 4, a compass disc 5 and an eyelet 6. Parts on the back shown on FIG. 4 are; rotating disc 7, rotating disc 8 and rotating disc 9, a wind speed and direction apparatus 10, having on its top part a coupling 11 and a wind direction flag 12.
FIG. 1 shows all the operating parts on the front side. All parts of this invention may be made of vinyl plas tics, or metal. To operate this computer you turn dial 2 on part 1 to a place on 1 where the wind direction is indicated. Each dial has an arrow for placement. Then you read the plus or minus figure in yards to be subtracted or added from head or tailwinds. Note that dial 2 calculates and yards while dial 3 calculates 200 and 300 yards. This invention could add dials to it giving more selection and answers. Next you turn dial 4 to the estimated hitting distance and it gives you the club to use in your category. Note that part 4 is adjustable for a fast or slow course calculation and that parts I 2 & 3 both have arc readouts which give the golfer a compensating vector in degrees as to where to hit the 3 ball so that it will go to a given spot under any condition. Dial 5 is the compass dial, it enables a person to measure the directions of movement on a golf course. Dials all are rotatable in either direction are joined together by a bolt or eyelet 6.
FIG. 2 shows a side view of the entire computer, having all the parts explained above in FIG. 1 plus the various apparatus on the back. Disc 7 counts total game strokes for up to 4 or more players, it rotates in either direction. Disc 8 is rotatable and it records the playing hole number, disc 9 is also rotatable it counts the hole strokes for the players. Part 10 is an apparatus for measuring wind speed, it has a coupling 11 and a wind direction flat 12 and a leveling device 13.
FIG. 3 shows a side view of a condensed pocket model of the invention. This may utilize both sides for the information found only on FIG. 1 part 1 being the base, 2' and 3' the rotatable discs for wind & are, part 4 the club selector, part 5' the compass and part 6' the eyelet.
FIG. 4 is the rearview, it has been explained in FIG. 2 above.
FIG. 5 shows operating examples of the computer's effectiveness in dealing with the normal problems encountered in playing golf on a windy day. Note that the example shows a wind force of 30 MPH tailwind at 45 wherein the player gains 58 yards read on the computer from the wind assist on a 300 yard shot. Therefore, to still hit the ball 300 yards and not further one would change the club according to the computers information and strive to hit the ball 250 yards wherein the wind will complete the task making a total of 308 yards. The wind direction is a tailwind (from the rear) at a 45 angle. The player would find the arc information on the windage dials part 2 & 3, FIG. 1. In this example the trajectory chart shows a angle of 10 to the left which will compensate for the wind factorand place the ball in the desired spot.
