BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor golf practice device, and more particularly to an indoor golf practice device that allows golf practice to be performed under conditions similar to those found on an actual course.

0002

[Prior Art] Conventionally, indoor golf practice devices include:
A shot analysis sensor that determines the flight direction of the ball based on the position of collision between the club and the ball and the trajectory of the club is attached to a batting stand whose inclination angle can be changed by air pressure, etc., or it is installed on the side of the batting stand. There is a known monitor device that displays a screen that matches the flight distance, direction, and height of the ball.

0003

[Problem to be Solved by the Invention] By the way, the former method, in which a shot analysis sensor is installed on the batting stand, can accurately analyze shots even when the distance to the net is short.
It does not require a large space like an open-air golf driving range, and the inclination angle of the batting table can be changed according to the angulation of the course, so it has the advantage of enabling more practical practice.

However, since it is not possible to hit a shot while visually checking the distance from the batting position to the cup, in reality, all you can do is practice to avoid making mistakes, and the distance is the same as when you are out on the actual course. It is impossible to practice golf in these conditions.

On the other hand, the latter, which has a monitor device, has the advantage that since the actual course is displayed on the monitor device, it is possible to practice golf in conditions closer to the actual course.

However, since the monitor device is installed on the side of the batting stand, it is not possible to check the displayed content when taking a tee shot, and the player has no choice but to check the information after the fact. For this reason, there is a problem in that even though the actual course is displayed, it is not possible to practice golf under the same conditions as when playing on the actual course.

[0007] That is, in the conventional device, when taking a tee shot, the ball is hit aiming at a mark attached to the net, but on an actual course, there are no such marks, and there are no such marks. Depending on the surrounding conditions, it may not be a good idea to aim the ball in front of the center. However, the conventional device has a problem in that it cannot cope with such a case.

The present invention has been made with these points in mind, and it is an object of the present invention to provide an indoor golf practice device that allows golf practice to be performed under the same conditions as when playing on an actual course. purpose.

[0009]

[Means for Solving the Problems] As a means for achieving the above object, the present invention provides a screen that also serves as a mat and is provided with an impact sensor that outputs a signal of the position where the ball hits and a signal of the impact strength; a projection device that stores a plurality of still images related to a golf course and projects any still image on the screen; a batting platform whose inclination angle is adjusted by a drive device; a shot analysis sensor that detects the collision state and the trajectory of the club and determines the flight direction of the ball; calculates the arrival point of the ball based on the signals from the impact sensor and the shot analysis sensor; The present invention is characterized in that an arithmetic and control device for controlling the projection device and the drive device are respectively provided.

In the present invention, it is preferable to provide at least one of the following: a bunker shot stand, a putter stand, and a rough turn stand; It is more preferable to provide a tilting device for adjusting the tilting angle of the tilting device, and to control this tilting device by the arithmetic and control device.

Further, in the present invention, at least one of a blower device that adjusts wind direction, wind speed, and wind force, a temperature controller that adjusts temperature, and a humidity controller that adjusts humidity.
It is preferable that a device or a sound device that outputs sounds such as bird sounds be provided, and these devices be controlled by the arithmetic and control device.

0012

[Operation] In the indoor golf practice device according to the present invention, the course viewed from the starting position is displayed on the screen that also serves as a mat. The practitioner hits the ball on the bat while watching this video. When you hit a ball, a shot analysis sensor determines the direction of flight of the ball, i.e., whether it was straight, hooked, or sliced, and an impact sensor determines where on the screen the ball hit and with what impact. is detected. Then, in the arithmetic and control device, the arrival point of the ball is calculated based on these data.

[0013] When the arrival point of the ball is calculated, a corresponding still image is selected and displayed on the screen, and the angulation of the arrival point is reproduced by the driving device. Therefore, it is possible to practice golf under the same conditions as when playing on an actual course.

[0014] In the present invention, by providing a bunker shot stand, a putter stand, or a rough turn stand, it is effective for practicing recovery shots when making a missed shot and practicing putting. At this time, by adjusting the angle of inclination of the putter's batting stand up to the cup using a tilting device controlled by an arithmetic and control unit, it becomes possible to practice putting in accordance with the course.

Furthermore, in the present invention, by providing a blower device, a temperature control device, a humidity control device, or a sound device and controlling these devices with an arithmetic control device, it is possible to practice with a more realistic feeling.
