DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for simulating skiing, and more particularly to an apparatus for simulating skiing in which a ski jump can be performed by taking off from a jumping platform and the sensation of excitement and exhilaration can be simulated. .

[0002]

2. Description of the Related Art Various devices for simulating the experience of skiing using virtual experience, so-called virtual reality, have been developed in particular as game machines. In many cases, for example, a skier or player operates a ski or a pedestal imitating the ski to control a skier's run line on a computer graphics image, for example, to clear obstacles and a course while clearing obstacles and courses. It is like enjoying a good run.

[0003]

However, in the above-mentioned conventional ski simulation experience apparatus, the excitement and exhilaration of actual skiing cannot be enjoyed. At the same time, ski jumping is the most exciting and exhilarating of such skis, but actual ski jumping can only be performed by some skiers with rigorous training. Therefore, there has been a demand for a simulated ski experience device that allows anyone to easily enjoy the excitement and exhilaration of ski jumping.

[0004] The present invention has been developed in view of these problems, and provides a simulated ski jumping device that can perform a simulated ski jump by taking off from a jumping platform, and at the same time, can experience the excitement and exhilaration. The purpose is to provide.

[0005]

In order to solve the above-mentioned problems, a ski simulating apparatus according to a first aspect of the present invention is an apparatus for simulating a ski jump caused by a crossing from a jumping platform. Angle adjustment means for adjusting the inclination angle of the left and right skis in the front-rear direction; display means for displaying a predetermined moving screen at least in front of the left and right skis; and at least forward and downward of the left and right skis A blower adjusting unit that adjusts the blower from one or both of them, and a controller that controls the inclination angle by the angle adjuster and the moving screen by the display unit and the blower by the blower adjuster according to a predetermined movement trajectory. It is characterized by having.

Here, the jumping platform refers to, for example, a railroad crossing platform of Schanze used in a general Nordic skiing competition. A railroad crossing is generally called a satz. Further, the predetermined movement trajectory is, for example, assuming such a shangze, a skier descends on a runway, then takes a level crossing at a railroad crossing stand, and after flying and falling, the landing slope,
5 shows a moving trajectory for landing in a so-called landing area. Therefore, the inclination angle, the moving screen, and the air blowing according to the predetermined moving trajectory indicate, for example, the inclination of the ski and the skier, the surrounding landscape, and the state of the wind related to the ski and the skier, which are generated by the series of movements. .

According to a second aspect of the present invention, in the ski simulation experience apparatus, the control means sets the predetermined movement trajectory from an inclination of a runway of the jumping platform and a load on a ski at a crossing. It is characterized by doing.

Here, the moving locus of the flight fall after the satz is determined by the initial speed of approach to the railroad crossing platform and the direction of the satz. Of these, the initial speed of approach to the railroad crossing is determined by the slope and length of the runway, except for the wind resistance to the skier. The direction of the sats is determined by the state of the load on each ski by the skier, that is, at what timing and how to step on the ski or the railroad crossing.
Therefore, if these are detected, the moving trajectory during the flight fall is inevitably determined.

[0009] In the ski simulation experience device according to a second aspect of the present invention, the left and right skis are each movable in the front-rear direction. This is a configuration for, for example, shifting the left and right skis back and forth so as to be able to take a so-called telemark posture, particularly for stabilization after landing, that is, after landing.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a ski simulation experience apparatus according to the present invention will be described with reference to the drawings.

First, FIG. 1 shows an outline of a ski simulation experience apparatus according to the present embodiment. 1L and 1R in the figure are left and right skis (synonymous with skis). The ski 1L of the present embodiment,
The 1R uses a jumping Nordic ski as it is, and therefore a binding 20 for connecting a ski boot (mainly a toe, ie, a toe side) is attached to each ski 1L, 1R. The skis 1L and 1R do not necessarily have to be usable for actual skiing, and may have a structure imitating only the form or a structure having only a skier (including a player or the like) mounted thereon. However, as will be described later, the skier on the skis 1L and 1R receives air from the front or from below, and inclines together with the skis 1L and 1R. It should be able to be fixed to the skis 1L, 1R. In addition, this ski 1
The right side of L and 1R in the drawing, that is, the side on which the shovel portion is formed is referred to as the front or top side, and the opposite side is referred to as the rear or tail side.

Each of the skis 1L, 1R on the top side and the tail side is connected to a piston rod 2a of an independent hydraulic cylinder 2, and a cylinder tube 2b of each hydraulic cylinder 2 is independent of left and right. It is fixed vertically on the gantry 3. That is, two hydraulic cylinders 2 are erected vertically upward on a gantry 3 disposed on the left and right, and the left and right skis 1L, 1 are mounted on the upper end of the piston rod 2a.
R are connected on the top side and the tail side, respectively. The skis 1L, 1R and the piston rod 2a of each hydraulic cylinder 2 are connected to each other by a pin connection structure that allows only rotation in substantially the front-rear direction. Also,
The operation of each hydraulic cylinder 2 is controlled by a working fluid pressure from a hydraulic actuator unit 11 including a fluid pressure source and a pressure control valve (not shown). Therefore, this actuator unit 1
By adjusting the working fluid pressure from 1, the expansion and contraction of the piston rod 2 a of each fluid pressure cylinder 2 can be adjusted, so that not only the overall height adjustment of each ski 1 L, 1 R but also their The angle of inclination can be adjusted individually. The connection structure between the skis 1L, 1R and the fluid pressure cylinder 2 is, for example, as described later, in order to facilitate the balance when the skier intentionally takes a V-shaped flight, the inside of the ski, the so-called inside, However, it may be allowed to slightly move inward.

In the present embodiment, the left and right gantry 3 can be moved only in the front-rear direction via the rollers 4. Reference numerals 5F and 5R in the figure denote blocks provided at the front and rear moving ends of each gantry 3, respectively.
Is the front block 5F and the return spring 6
Connected by The rear block 5R is provided with a stopper 7 via a spring 7a protruding toward the gantry 3 side. Therefore, as each mount 3 moves back and forth, the skier whose left and right legs are connected to the skis 1L and 1R intentionally shifts both skis 1L and 1R in the front-back direction, for example, to change the telemark posture. It can be taken,
The return spring 6 is configured so that both skis 1L and 1R naturally line up when the telemark posture is released, and the stopper 7 is used for both skis 1L and 1R.
L, 1R act so as not to be too far back and forth.

Screens 8F, 8L (8R), and 8U are provided in front of, on the left, right, and below, the skis 1L, 1R so as to surround both skis. The screens 8F, 8L (8R), and 8U project images from an image processing device described later. More specifically, the screens slide down the runway of Schanze, cross at a crossing platform, and fly down. A skier who lands on a landing slope (landing area) displays the surrounding scenery seen in the meantime. The setting of the moving screen according to the moving locus will be described later in detail. Also,
The screens 8F, 8L (8R), and 8U have a mesh structure so as not to obstruct the air sent from each fan to the skier, which will be described later.

Also, for the skis 1L, 1R, the back side of the front screen 8F, ie, for the skis 1L, 1R, the front and front screens 8F and the back side of the lower screen 8U, ie, for the skis 1L, 1R. Are fans 9F and 9 that are rotated by a motor 9a at obliquely lower fronts, respectively.
U is provided. These fans 9F and 9U send the air over the screens 8F and 8U, respectively, and the intensity of the air can be adjusted by adjusting the rotation speed of the motor 9a. In addition,
In the present embodiment, the fans are arranged in front of the skier and diagonally below and forward from the characteristics of the ski jump, but fans may be provided in various places according to the form of flight.

On the other hand, a load applied to the hydraulic cylinder 2, that is, the ski 1
An acceleration sensor 12 for detecting loads on the top and tail sides of the L and 1R is provided. A roller 4 of each pedestal 3 is provided with a position sensor 12 for detecting the position of the pedestal 3, that is, displacement. Then, control signals for reading the detection signals of these sensors 12 and 13 and adjusting the working fluid pressure to the respective hydraulic cylinders 2, that is, controlling the actuator unit 11 to adjust the inclination angles of the skis 1L and 1R. The motor 9 is used to adjust the signals and the air flow from the fans 9F and 9R.
A control unit 10 for outputting a control signal for controlling the rotation speed of a is provided. The control unit 10 includes an arithmetic processing control device such as a microcomputer (not shown), and its logic and control mode will be described in detail later.

Next, the operation of the ski experience apparatus according to the present embodiment will be described with reference to the control logic executed by the control unit 10. In this embodiment, as described above, a series of ski jump simulations is first performed, in which the skier descends down the runway of Schanze, sats at the railroad crossing, then falls and flies, stops at the landing area and stops. Therefore, the control unit 10 first performs arithmetic processing in accordance with the set inclination of the runway, and for example, relatively contracts the hydraulic cylinder 2 on the top side and extends the hydraulic cylinder 2 on the tail side. By generating and outputting a control signal, the skis 1L and 1R are tilted so that the top sides thereof are downward and the tail sides thereof are upward as shown in FIG. 2A. At this time, the fan 9F on the front and the fan 9U on the obliquely lower front control the rotation speed of each of the motors 9a so that the initial speed of the descent is zero and gradually increases. Since the runway is inclined, the obliquely lower front fan 9U is made much stronger than the front fan 9F.

After that, when the skier and the ski enter the supposed crossing platform, the inclination angle of the ski is controlled in accordance with the inclination angle in the same manner as described above, and the skier at the crossing platform is skied by the skier. The state of the load is detected by the acceleration sensor 12, and the displacement of the ski in the front-rear direction at that time is detected by the position sensor 13. The initial speed at the time of the satz is substantially determined from the inclination angle and the length of the runway as described above. In addition, the direction of the sats is determined based on, for example, whether the load has been appropriately moved from the tail side of the ski to the top side at an appropriate timing, or whether both skis 1L and 1R have been shifted back and forth. Therefore, if all of these conditions are properly performed, skiing is performed at an angle at which the ski and the skier reach farther, and the falling point becomes closer as the skiing condition deviates from the proper conditions. Therefore, by using these, for example, the control unit 10 performs an arithmetic process based on a falling motion equation having an initial velocity to the side, so that the movement locus of the ski and the skier can be obtained. In addition, for advanced users, when the appropriate sats are not performed, for example, a change in which the top side of the skis 1L and 1R falls may be expressed by the respective fluid pressure cylinders 2. It is desirable not to feel unbalanced.

When the sats are finished in this way, the skis shift to a flight fall. In this case, for example, as shown in FIG. 2B, the skis 1L and 1R are leveled so that a flight distance can be obtained with respect to the wind force from below. Alternatively, the inclination angle is controlled so as to give a slightly higher elevation angle. Since the movement trajectory during the flight fall basically follows a parabolic fall having an initial velocity to the side, the movement speed to the front does not change, so that the blowing from the front fan 9F is as strong and almost as at the time of the satz. To be constant. On the other hand, if the skits are performed in a good direction, the ski and the skier are protruding horizontally or slightly upward, so that the initial blowing from the obliquely lower front fan 9U is zero. However, the blow from the obliquely lower front fan 9U is gradually increased in accordance with the above-described parabolic fall speed change. For advanced users, for example, when the load on the left and right skis 1L and 1R during flight and the front-back difference change,
Correction may be performed so that the skis 1L and 1R fluctuate and the flight distance may be shortened, but it is preferable that the skier does not feel extreme imbalance.

Subsequently, since the landing is performed on the landing area, the inclination angles of the skis 1L and 1R are controlled in accordance with the inclination angles. At the moment of this landing, there is a sense of realism if a slight impact such as a feeling of thrust is given by each of the fluid pressure cylinders 2, and the landing is such that the top sides of the skis 1L and 1R come into contact sequentially from the tail side. Therefore, by giving the manner of impact in the order shown in FIG. 2B, the sense of reality is further enhanced. Further, while the landing area after the landing still has the inclination angle, the air blowing just before the landing is maintained.

Eventually, the skis and skiers move to the finish area following the landing area, that is, to a flat ground without an inclination angle. From this moment, the obliquely lower front fan 9U stops so as not to blow air therefrom. Then, since the skiing stops at this finish area, the air blowing from the front fan 9F is gradually reduced to zero finally. In addition, the skier may open the skis back and forth before and after, so-called telemark posture. In this case, the gantry 3 on which the left and right skis 1L and 1R are mounted can move only in the front-back direction. Is used effectively.

The control unit 10 is deployed around the skier by analyzing the movement trajectory as described above during the series of ski jumps in accordance with the control of the inclination angle and the wind of the ski. To derive the landscape to be displayed,
F, 8L (8R), and 8U, by generating and outputting a control signal to an image processing device (not shown), the skier can directly feel the change in the landscape along with the change in gravity and wind during the ski jump. Yes, you can enjoy the excitement and exhilaration of a real ski jump.

As described above, the actuator unit 1
1 and each fluid pressure cylinder 2 constitute angle adjusting means of the ski simulation experience apparatus of the present invention, and similarly, each screen 8F, 8L (8R), 8U and the image processing apparatus constitute display means, and the front fan 9F, the obliquely lower front fan 9U and the respective motors 9a constitute a ventilation adjusting means, and the control unit 10 constitutes a control means.

In the above embodiment, each screen has a mesh structure in order to send air from each fan to the skier through the screen. However, for example, by arranging appropriate ducts, for example, from the left and right sides of the front screen, etc. If the wind blows out toward the skier, it is not necessary for each screen to have a mesh structure. Further, in such a case, what displays the moving screen is not limited to the screen, and for example, a large monitor (video tube) can be used.

Further, such an image display means may be provided only at the front which is at least the most influential for the skier. However, in order to produce a more powerful force, the left and right and lower parts as in the above embodiment are required. Is desirably provided.

In the above embodiment, only the inclination angle of the ski is controlled. However, the height of each ski can be controlled by synchronous control of the fluid pressure cylinder. , And may be lowered downward during downhill or landing on the runway to enhance the sense of reality.

In the above embodiment, the ski can be moved only in the front-rear direction. For example, the ski or the pedestal is opened so that the top side is opened using the tail side of the ski as a fulcrum. A moving range may be set. In this case, if the inside of each ski falls slightly inward from the V-shaped balance, there is no uncomfortable feeling.

Also, in the above embodiment, the flight distance can be estimated as described above, and the flying point can be derived from the change in the load on both skis and the difference between before and after the skis. It is also possible to perform scoring like competition. The scoring may also take into account the stability of the landing due to the telemark attitude as described above.

[0029]

As described above, according to the ski simulating apparatus according to the first aspect of the present invention, for example, the rider descends on the runway of a jumping platform, takes a level crossing at a crossing platform, drops in flight, and lands. According to a predetermined movement trajectory landing on a slope, for example, by controlling the moving screen including the inclination angle of the skis and skiers generated along with the series of movements and the landscape around the skis and the state of air blowing related to the skis and skiers. ,
You can enjoy the same excitement and exhilaration as an actual ski jump.

Further, according to the ski simulating experience device according to the second aspect of the present invention, the initial speed of approach to the railroad crossing platform obtained from the inclination of the runway and the direction of the railroad crossing obtained from the state of the load on each ski. By obtaining the predetermined movement trajectory during the flight fall based on this, a ski jump closer to reality can be simulated.

According to the present invention, the left and right skis movable in the front-rear direction can take the telemark posture for stabilization after landing. Thereby, a ski jump closer to reality can be simulated.
