The clearance between the loading platform 61 and the loading flip-up door 62 and the clearance between the loading flip-up door 62 and the endless belt 10 should be as narrow as possible so that an object is not pinched. The boarding-up door 62 becomes a horizontal floor when the user gets on the board, and stands up when the user gets on the endless belt 10 and becomes a wall that prevents the user from falling backward.

As shown in FIG. 1 (C), a landing cushion 65 is provided in front of the ski simulator in order to safely land a user jumping forward. As the inclination of the endless belt 10 is changed by the vertical inclination variable device 40 and the height of the front end portion of the endless belt 10 is changed, the height position of the landing cushion 65 is changed to change the front end of the endless belt 10. It is desirable to minimize the difference from the.

As shown in FIG. 1, the endless belt 10
A handrail 71 and a side drop prevention plate 72 are provided on the left and right sides of the support frame 39 so as to prevent the user from falling off to the side.

A projection device (not shown) for projecting an image is provided. Further, although not shown, a blower device may be provided to blow air to the user on the endless belt 10 so as to blow the wind from the front.

Next, the operation of the embodiment shown in FIG. 1 will be described. When the drive drum 22 is rotationally driven by energizing and rotating the variable speed motor 21, the endless belt 10 is tensioned by the tension drum 23 and is in contact with the drive drum 22 at a predetermined pressure. The endless belt 10 is driven. The endless belt 10 is adjusted by the meandering prevention device 26 and moves smoothly. When a user wearing a ski passes through the loading platform 61, passes over the horizontal loading flip-up door 62, and rides on the endless belt 10, the endless belt 10 is inclined so as to descend forward. Since the surface of the endless belt 10 is slippery, the user slides forward. However, the endless belt 10 is moving from the front to the rear,
By appropriately changing the rotation speed of the variable speed motor 21 to balance the rising speed of the endless belt 10 with the downhill speed of the user, the user can continue the downhill movement on the endless belt 10. The sliding surface rollers 24 provided on the lower surface of the endless belt 10 at appropriate intervals are
The endless belt 10 is prevented from being locally depressed by the weight of the user.

In FIG. 1, after the user has transferred onto the endless belt 10 from the horizontal hoisting door 62, the hoisting door 62 stands up and becomes a wall as shown in FIG. Prevents it from being pushed back and falling off. In addition, the handrails 71 and the side dropout prevention plates 72 provided on both sides of the endless belt 10 prevent the user who slides down from falling sideways. Further, the landing cushion 65 provided in front of the endless belt 10 allows the user, who is sliding down, to land safely when jumping forward.

In FIG. 1, a hydraulic pressure such as oil or air is fed into a vertically tilting cylinder 41 of a vertically tilting variable device 40 to cause a rod 42 to project, whereby the supporting frame 3
If the front end of 9 is raised and the inclination of the endless belt 10 in the front-rear direction is reduced, the slope becomes gentle and the user's downhill speed also becomes slow. At this time, the rotation speed of the variable speed motor 21 may be slowed down to slow down the rising speed of the endless belt 10 to balance it with the downhill speed. On the contrary, if the front end of the support frame 39 is lowered and the inclination of the endless belt 10 in the front-rear direction is increased by extracting the fluid pressure of the vertically inclined cylinder 41 and accommodating the rod 42, a steep slope is created and the user slides down. Speed up. At that time, the rotation speed of the variable speed motor 21 may be increased to increase the rising speed of the endless belt 10 to be balanced with the downhill speed. The inclination and drive speed of the endless belt 10 may be set according to the skill and desire of the user. Further, during the downhill, the inclination of the endless belt 10 can be changed slowly and the driving speed can be changed slowly, so that the downhill state can be changed.

Further, the lateral tilt cylinder 5 of the lateral tilting device 50.
If the support frame 39 is tilted to the left or the right and the endless belt 10 is tilted to the left or the right by moving the fluid pressure in and out of the rod 1 and moving the rod 52 in and out, it is possible to practice the skiing in the diagonal direction. it can. Also, if the left and right tilt angles are changed so as to swing left and right during the downhill, it will be easier to practice the zigzag downhill.

In FIG. 1, if a landscape that is noticeable during skiing at an actual ski resort is projected on a video screen 81 by a projection device (not shown), a user skiing down on the endless belt 10 can actually ski. Will give rise to the feeling of In addition, if a blower (not shown) blows wind from the front to the user corresponding to the downhill speed,
Since the user takes a posture to cope with the air resistance at the time of downhill like a real ski, it is also useful for practice, and the feeling of a real ski is further increased. The wind velocity of the wind hitting the user by this blower and the flow velocity of the image are equal to the downhill velocity of the user, that is,
It suffices to match the moving speed of the endless belt 10 which is changed by changing the rotation speed of the variable speed motor 21. In addition, an audio device may be provided to interlock with the image and wind.

In the embodiment shown in FIG. 1, the rear portion of the support frame 39 has a constant height, and the vertical tilt varying device 40 is applied to the portion supporting the front portion of the support frame 39.
The front portion of the support frame 39 may have a constant height, and the vertical inclination varying device 40 may be applied to the portion supporting the rear portion of the support frame 39 to change the inclination of the endless belt 10 in the front-rear direction. Further, by providing a vertical tilt variable device 40 on both front and rear parts, the height of both front and rear parts can be changed,
The inclination of the endless belt 10 in the front-rear direction may be changed. When the height of the rear portion of the support frame 39 is changed, it goes without saying that the height of the loading platform 61 is also changed at the same time.
