Description

The present invention relates to a screen for a virtual golf machine that projects a virtual golf image on the screen.

In recent years, it has become possible to project images of a virtual golf course and golf balls onto a screen at a golf driving range, allowing users to experience as if they were actually playing on the golf course while staying indoors. Virtual golf machines are commonly used.

In virtual golf, the images projected on the screen are virtual, but because practice is conducted by actually hitting the golf ball toward the screen, the impact of hitting the ball will cause the screen to become dirty and worn. Become. In addition, while the screen for the virtual golf machine is an expensive product that is durable and quiet, if even a part of the screen has a problem, the entire screen must be replaced, and the cost of replacement is burdensome. was a big one.

In order to solve the above-mentioned problem, Japanese Patent No. 5788594 (hereinafter referred to as "Patent Document 1") describes that "these are arranged side by side along a predetermined direction, overlap each other in a predetermined portion, and are arranged at a predetermined angle from a predetermined direction. a plurality of screen element members installed to be inclined; and a frame holding the plurality of screen element members, wherein the frame includes a support guide portion having a shape corresponding to the inclination of the screen element members; is a transmissive screen for screen golf, characterized in that a plurality of sub-frames for supporting a part of the plurality of screen element members are joined together.
According to the screen of Patent Document 1, when a problem occurs in a part of the screen or when washing becomes necessary, it is possible to separate and replace only the corresponding part of the screen.

Japanese Patent No. 5788594

However, the invention of Patent Document 1 is composed of a large number of parts, and it is said that the more separable screen elements are used, the more the load from the impact of a hit ball concentrates on the support guide and the screen element members, and the more likely they are to be damaged. I had a problem.
SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide a screen for a virtual golf machine that has excellent durability and reduces the cost required for replacement.

A screen for a virtual golf machine according to a first aspect of the present invention includes a main screen, a replacement screen, and an overlapping mechanism, and the back surface of the replacement screen can be detachably attached to a part of the front surface of the main screen by the overlapping mechanism. It is characterized by being layered.

By overlapping the back of the replacement screen on part of the surface of the main screen (the surface where the image is projected by the projector), the surface of the replacement screen where the replacement screen overlaps absorbs the impact of the ball. Because it receives it, the impact received by the main screen is greatly reduced. In addition, by making the main screen and the replacement screen detachable, it is possible to replace the replacement screen that is soiled or worn alone. Furthermore, by attaching the back surface of the replacement screen to only a portion of the front surface of the main screen, the cost required to replace the replacement screen is less than replacing the entire main screen. In addition, the dual structure of the main screen and the replacement screen improves the durability and quietness of the entire screen.
The overlapping mechanism preferably uses a hook-and-loop fastener or other impact-resistant material, but is not limited to a specific structure.

The larger the area of the replacement screen, the wider the range that can catch a hit ball, but the cost required for a single replacement increases. Therefore, it is preferable to stack a plurality of replacement screens of about 4 to 9 on the main screen, or to predict in advance the position where the screen is likely to wear, and to place the replacement screen in an appropriate range based on the predicted position. Heavy clothing.
The location where the screen is prone to wear depends on the facility environment of the virtual driving range, but is predictable. A specific method for predicting wear-prone locations of the virtual golf machine screen is described below.

As shown in FIG. 10, a virtual driving range 80 is provided with a screen 90 and a shot area 100 . The X-axis, Y-axis, and Z-axis are each vertical, and the screen 90 is installed so that its longitudinal direction is parallel (horizontal) to the Y-axis.
A projection line 120 is drawn from the tee 110 placed on the shot area 100 to the screen 90 in the positive Z-axis direction, and a projection line 122 is drawn from the contact point 130 between the projection line 120 and the screen 90 in the positive X-axis direction. If shot in the correct manner, batted ball 140 is more likely to hit screen 90 near projection line 122 and less likely to hit screen 90 away from projection line 122 .
On the other hand, since the launch angle α of a hit ball in a golf game greatly depends on the golf club used by the batter, it is difficult to specify the position in the X-axis direction where the hit ball 140 is likely to collide with the screen 90 . However, the launch angle of a hit ball in a golf game is approximately the same as the loft angle of a golf club, and a ball with a smaller launch angle has a higher ball speed and a greater impact on the screen. Therefore, in estimating the position where the screen 90 is likely to be worn, it is effective to assume the case of using a driver designed with the smallest loft angle (approximately 9 to 11 degrees) among general golf clubs. target.
For example, in a facility where the distance from the tee 110 to the screen 90 (the length of the projection line 120) is 5 m, assuming a shot using a driver with a loft angle (≈launch angle α) of 10°, the screen 90 It can be estimated that the center 150 of the wear-prone position is about 0.9 m from the contact point 130 in the positive direction of the X-axis.
The actual trajectory of the hit ball depends on the batter's skill, but in virtual golf, the distance from the shot area to the screen is generally set as short as about 4 to 5 m, so the sudden rotation of the hit ball The trajectory change is unlikely to occur, and the possibility of a large deviation in the impact position of the hit ball is low.

The virtual golf device screen of the second aspect of the present invention is characterized in that the replacement screen includes a rectangular area having a vertical length of 80 cm and a horizontal length of 60 cm.

Since the replacement screen includes the above rectangular area, it is possible to protect the area where the screen is easily worn, especially when a screwdriver is used, with a single replacement screen while reducing the cost of replacement. The shape of the replacement screen as a whole is not limited to a specific shape such as a rectangle or a circle.
Although the ball may come off the replacement screen and hit the main screen, it is extremely unlikely that the ball hits the same position repeatedly, and the main screen is different from the conventional screen. Since they have similar durability, the effect of these hit balls on the durability period of the main screen is negligible. When the applicant investigated conventional screens that had to be replaced in a plurality of virtual golf courses, the areas where the screens were visibly soiled and worn were all within the above rectangular area. was discovered.
In this specification, the vertical direction and horizontal direction of the main screen and the replacement screen are based on the state in which they are installed in the virtual golf driving range.

A screen for a virtual golf machine according to a third aspect of the present invention is the screen for a virtual golf machine according to the first aspect, wherein the shapes of the main body screen and the replacement screen are both substantially rectangular, and the vertical length of the main body screen and the vertical length of the replacement screen and are substantially equal to each other.

A screen for a virtual golf machine according to a fourth aspect of the present invention is the screen for a virtual golf machine according to the second aspect of the present invention, wherein the shapes of the main body screen and the replacement screen are both substantially rectangular, and the vertical length of the main body screen and the vertical length of the replacement screen and are substantially equal to each other.

According to the third and fourth aspects of the present invention, the main body screen and the replacement screen are substantially rectangular in shape, and the lengths in the vertical direction of both are substantially the same, so that the screens do not wear out regardless of the golf club used. A single replacement screen can comprehensively protect easily accessible positions, and facilitate manufacturing and processing.
It should be noted that the description of "substantially rectangular" in the present invention may include a square, and it is also possible to make the shape of either the main body screen or the replacement screen a square.

A screen for a virtual golf machine of a fifth aspect of the present invention is a screen for a virtual golf machine according to the first to fourth aspects of the present invention, wherein the overlapping mechanism projects the outer edge portion of the back surface of the replacement screen and the outer edge portion of the back surface of the replacement screen onto the front surface. It is characterized by being provided only on a part of the main body screen that has been formed.

By providing the heavy landing mechanism only at these positions, it is possible to reduce the risk of the heavy landing mechanism being damaged by the impact of the hit ball, and the inside of the replacement screen (excluding the outer edge), the replacement screen An air layer is generated between the main screen and the main screen, and the impact received by the main screen due to the collision of the hit ball can be further reduced.

The virtual golf device screen of the present invention can replace the replacement screen that has been soiled or worn due to the impact of a hit ball. improves.
