Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a distance measuring device for golf courses, and particularly for golf courses that allow players to easily measure distance during a round. The present invention relates to a distance measuring device that can be used for distance measurement.

[Prior Art] Conventionally, on golf courses, specific distances from the center of the green to the center of the fairway, such as 100 yards and 150 yards, are indicated using plants or the like for each hole.

[Problems to be Solved by the Invention] In the conventional example above, the distance from the green is displayed for each hole, but the fairway is wide (for example, even if the ball flies 250 yards from the teeing ground, the distance from the green is displayed on the left and right sides. In this case, there may be a difference of about 100 yards in the distance to the green.However, at present, this difference cannot be accurately determined.

Therefore, a technical problem has arisen that must be solved in order to be able to almost accurately determine the position of one's own ball and accurately recognize the direction and distance of the next line during a round. , the present invention aims to solve this problem.

[Means for Solving the Problems] This invention was proposed to achieve the above object, and involves creating a topographical map for each hole of a golf course, and marking the ball flight direction on the topographical map. Distance display lines perpendicular to the ball flight direction are displayed in parallel at fixed distance intervals, and the distances are displayed on the sides of the distance display lines, and a number of lines perpendicular to the distance display lines and perpendicular to the ball flight direction are respectively displayed. A distance measuring device for a golf course, characterized in that the distance display line and the perpendicular line are arranged in parallel to form a square, and the scale is the same as that of a topographic map created for each hole of the golf course. It is an object of the present invention to provide a distance measuring device for a golf course, characterized in that the distance display line and perpendicular line described above are displayed on a transparent body to form a grid.

[Operation] According to the invention described in claim 0, when a player is playing a round at the hole in question, the position of his or her ball hit from the teeing ground is determined based on the surrounding topography and topographical map. At this time, the position of your ball can be accurately determined by the squares displayed on the topographic map. Furthermore,
The direction and distance of the next row can be accurately recognized by the display displayed on the topographic map.

Next, when using the transparent body according to claim (2),
A topographical map of the hole in question is prepared in advance, and the player plays by carrying the transparent body along with this topographical map. Therefore, players can track the position of their ball by overlaying a transparent object on the topographical map of the hole they are playing. For example, the position of the ball hit from the teeing ground is checked against the surrounding topographical map and the position of the ball hit by oneself is determined. Then, using the teeing ground as a reference point, the transparent bodies are stacked in the direction of the center line of the fairway. In such a case, the position and flight distance of the ball can be accurately determined by using the squares, and the direction and distance of the ball can also be accurately recognized. For example, if the flint target is directly on the green, the reference point of the transparent body is overlapped from one point on the green in the direction of the ball's position. In such a case, the direction and distance of the target can be accurately recognized, and the player can greatly contribute to the round, including determining the club to be used by the player.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the attached drawings. 0) is a topographical map illustrating an example of a hole (through-the-breen) on a golf course. In the topographic map (1), (2) is the teeing ground, (3) is the fairway, (

Furthermore, the perpendicular lines (9) (Q)... to the distance display lines (8) (8)... are the distance display lines (8) (8)...
・From the 0 point, for example, draw parallel lines up to 275 yards on the ball flight distance display (.And, by displaying this perpendicular line every 25 yards, for example, the square cell 0

The distance display lines (8) (8)... and perpendicular lines (9) (9)... are displayed between the green (6) and the vicinity of the ball position, and the corresponding squares (!) θΦ...・I draw it. At this time, the distance display of the distance display lines (8), (8), etc. may indicate the distance from the center point of the green (6). In such a case, the player can accurately recognize the position of his ball and the direction and distance of the next line.

Next, an embodiment of the invention as claimed in claim (2) will be described with reference to FIG. 00 is a transparent body. The size of the transparent body θ0 may be such that it can be stored in a pocket. The transparent body has the distance indicating line (8) (

The display (8) (9) 01 If of the transparent body 01) is on the same scale as the topographic map. Therefore, when a player rounds a hole displayed on the topographic map, he or she looks at the surrounding topography and the topography on the topographic map to determine the position of his or her ball on the topographic map. Then, the transparent body θ0 is superimposed on the topographic map. First, when you want to know the flight distance of the ball, the tee position of the teeing ground (2) is set as 0 point, and the transparent body 00 is placed in the direction of the flight of the ball. If they are overlapped along the line, they can be immediately recognized by the distance display line (8). Furthermore, the direction and distance of the light can be measured as described above (for example, if the target point on the green is set as the 0 point and the transparent body 00 is stacked toward the ball position, the direction and distance of the light can be accurately recognized. .

Note that this invention can be modified in various ways without departing from the spirit of the invention, and it goes without saying that this invention extends to such modifications.

[Effects of the Invention] According to the present invention, a distance display line and a perpendicular line are provided on a topographic map displayed at a constant scale for each hole of a golf course, and squares are displayed in an orderly manner. Therefore, the player can accurately recognize the direction and distance to hit the ball. That is, when hitting from the teeing ground, or
The positions of the second and third hitters can be accurately recognized by the squares and distance display lines, and the direction and distance of the lantern can also be accurately grasped at the same time.

Furthermore, the case where a transparent body is used is exactly the same as described above. Therefore, this invention is truly a valuable invention in various ways, such as being able to accurately recognize the direction and distance that players want to know most accurately, as well as the positions of rough, bunkers, hazards, etc.
