Description

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, so that a simulated ski jump can be performed by crossing from a jumping platform using real skis, and at the same time, the sensation and exhilaration can be experienced. It is an object of the present invention to provide a ski simulation experience device.

[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. A mount having a predetermined coefficient of friction, and a portion mounted on the slide surface of each of the left and right skis and mounted on the mount, and having a coefficient of friction with the mount in contact with the mount. An intermediary member provided with a lubricating member to be reduced, angle adjusting means for adjusting an inclination angle of the mounting table in the front-rear direction, display means for displaying a predetermined moving screen at least in front of the left and right skis, Air blowing adjusting means for adjusting air blowing from either the front or the lower side of the left and right skis, a tilt angle by the angle adjusting means, a moving screen and a moving screen by the display means in accordance with a predetermined moving trajectory. It is characterized in that a control means for controlling the air blowing by the adjustment means.

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. . Also, the skis referred to here are real skis that can be used for actual jumping or gliding.

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.

According to a third aspect of the present invention, in the simulated ski experience apparatus, the mounting table has a stainless steel plate on an upper surface on which the intermediate member is mounted, and Teflon is used for the lubricating member. It is characterized by the following.

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. As described below,
Since the skiers on the skis 1L and 1R receive air from the front or from below and tilt with the skis 1L and 1R, the legs of the skiers can be fixed to the skis 1L and 1R to avoid danger. Should be so. The right side of the skis 1L 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.

The left and right skis 1L and 1R are mounted on a mounting plate 3 made of a stainless steel plate via an intermediary member 4 described later. The mounting base 3 is connected to the piston rods 2a of four independent hydraulic cylinders 2,
The cylinder tube 2b of each fluid pressure cylinder 2
It is fixed vertically on top. That is, four fluid pressure cylinders 2 are erected vertically upward on a pedestal 13 in a leg shape, and a mounting table 3 at the upper end of the piston rod 2a corresponds to the top side and the tail side of the skis 1L, 1R. It is connected at the site where Further, the mounting base 3 and the piston rod 2a of each hydraulic cylinder 2 are connected by a pin connection structure or the like that allows only rotation of the ski in substantially the front-rear direction corresponding to the front-rear direction of the ski. The operation of each hydraulic cylinder 2 is controlled by a hydraulic fluid pressure from a hydraulic actuator unit 11 including a fluid pressure source and a pressure control valve (not shown).
Therefore, by adjusting the working fluid pressure from the actuator unit 11, the expansion and contraction of the piston rod 2 a of each fluid pressure cylinder 2 can be adjusted, so that the overall height of the mounting base 3 can be adjusted. The angle of the inclination in the front-back direction can be adjusted.

On the other hand, as shown in FIG. 2A, the intermediate member 4 is a sliding surface of the skis 1L and 1R (the back surface of the ski is shown).
And a lubricating member 5 attached to the lower surface thereof. The frame structure 14 is a box-shaped or frame-shaped frame smaller than the running surface of general skis 1L and 1R, and a fixing member for fixing the skis 1L and 1R is disposed at the front end and the rear end thereof. Have been. As shown in FIG. 2B, the fixing member includes a coil spring 7 disposed inside the frame so that the axes of the skis 1L and 1R coincide with each other in the lateral direction, and both ends of the coil spring 7 are inserted into the frame. And a holding member 6 that is bent upward. The interval between the upper bent portions of the two holding members 5 connected by one coil spring 7 is set to be slightly smaller than the lateral width of the general skis 1L and 1R, and when the skis 1L and 1R are fitted between them. The skis 1L and 1R are sandwiched between the upper bent portions of the two holding members 6 by the elastic force of the coil spring 7.

A lubricating member 5 made of a Teflon member is provided on a lower surface of a central portion of the frame structure 14 where the fixing member is not provided to reduce a coefficient of friction with the mounting table 3 made of the stainless steel plate. Is installed. Therefore, with the skis 1L and 1R fixed to the intermediate member 4,
When a skier rides on the skis 1L, 1R, the skier has a low coefficient of friction between the lubricating member 5 made of a Teflon member and the mounting base 3 made of a stainless steel plate, and the skiers 1L, 1R have the same friction coefficient as on an actual snow surface. Can be moved sideways or backward by sliding. As a result, as described later, the skier can take a V-shaped flight shape during flight, or take a telemark posture after landing. A rubber protrusion 4a is provided downward from the rear end of the frame structure 14. this is,
As will be described later, when the mounting table 3 is inclined in the front-rear direction for both the skis 1L and 1R, the projections 4a are hooked on the rear end of the mounting table 3 and stop there.

A screen 8 is provided in front of and right and left of the skis 1L, 1R so as to surround both skis.
F, 8L (8R) are provided. This screen 8
F, 8L (8R) is for displaying an image from an image processing device described later. More specifically, the vehicle slides down the approach road of Schanze, crosses at a railroad crossing, falls, flies, and falls on a landing slope (landing slope). This is the display of the surrounding scenery seen by the skier landing on the area. The setting of the moving screen according to the moving locus will be described later in detail. The screens 8F and 8L (8R) have a mesh structure so as not to obstruct the air sent from each fan to the skier, which will be described later.

The skis 1L and 1R are located on the back side of the front screen 8F, ie, the skis 1L and 1R are at the front and the lower side of the front screen 8F, ie, the skis 1L and 1R are obliquely downward. Fans 9F and 9U which are rotated by a motor 9a are provided at the front, respectively. 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 the present embodiment, the fans are arranged in front of the skier and diagonally below and forward from the characteristics of ski jumping, 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. Then, the detection signal of each of these sensors 12 is read to adjust the working fluid pressure to each of the fluid pressure cylinders 2, that is, the ski 1
Control signals for controlling the actuator unit 11 to adjust the inclination angles of the L, 1R and the fans 9F, 9R
There is provided a control unit 10 for outputting a control signal for controlling the rotation speed of the motor 9a in order to adjust the air flow from the motor 9a. 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 simulation 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. A control signal is generated and output, and the mounting table 3 is inclined such that the top sides of the skis 1L and 1R are downward and the tail sides are upward as shown in FIG. 3a. At this time, the air flow from the front fan 9F and the obliquely lower front fan 9U is zero in the initial stage of the descent, and is gradually increased as the motors 9a and 9b move.
Is controlled, but the intensity of the air blown from each fan is made much stronger from the diagonally lower front fan 9U than from the front fan 9F because the approach path is inclined.

After that, when the skier and the ski enter the imaginary crossing platform, the inclination angle of the mounting table 3 is controlled in accordance with the inclination angle in the same manner as described above, and the skier at the crossing stage is skied by the skier. The acceleration sensor 12 detects the state of the load on the vehicle. 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. The direction of the sats is determined based on, for example, whether or not the load has been appropriately moved from the tail side of the ski to the top side at an appropriate timing. 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, using these, for example, the arithmetic processing based on the falling motion equation with the initial velocity to the side is performed by the control unit 1.
By performing the setting at 0, the locus of movement of the ski and the skier can be obtained. For advanced users, when the appropriate sats are not performed, for example, the tops of the skis 1L and 1R may change so as to fall down.
May be expressed, but it is desirable that the skier does not feel extreme imbalance.

When the sats are finished in this way, the skis shift to a flight fall. In this case, as shown in FIG. 2B, for example, the skis 1L and 1R are almost moved so as to gain a flight distance against the wind force from below. The inclination angle of the mounting table 3 is controlled horizontally. In accordance with this, the skier may slide the skis 1L and 1R sideways as needed to take a V-shaped flight shape in order to extend the flight distance. 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 sats are performed in a good direction, the ski and the skier jump out almost horizontally, 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, 1R during flight changes, the skis 1L, 1R
Correction may be performed so that the R may fluctuate or the flight distance may be shortened, but it is desirable that the skier does not feel extreme imbalance.

Subsequently, since the landing is performed on the landing area, first, the inclination angle of the mounting table 3 is controlled in accordance with the inclination angle. 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 to the mounting table 3 in the order shown in FIG. 2B, the sense of reality is further increased. Further, while the landing area after the landing still has the inclination angle, the air blowing just before the landing is maintained.

Eventually, the ski and the skier move to the finish area following the landing area, that is, to a flat ground without an inclination angle, but 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. Alternatively, the skier may open the skis back and forth before or after the so-called telemark posture.

The control unit 10 is deployed around the skier by analyzing the movement trajectory as described above during this 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) generates and outputs a control signal to an image processing device (not shown), so that the skier can attach the real skis 1L, 1R and change the landscape during the ski jump by gravity or wind. You can feel directly with the change of the, and you can enjoy the excitement and exhilaration as if you were actually ski jumping.

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. Similarly, each screen 8F, 8L (8R) U and image processing apparatus constitute display means, and the front fan 9F , The obliquely lower front fan 9 </ b> U and each motor 9 a constitute a blower adjusting unit, and the control unit 10 constitutes a controller.

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.

Such an image display means may be provided at least only in front of the skier, which is the most influential for the skier. However, in order to produce more power, the image display means may be provided on the left and right as in the above embodiment. It is desirable to provide.

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, since the flight distance can be estimated as described above, it is also possible to perform a scoring such as a Nordic ski jumping competition by using them.

[0029]

As described above, according to the ski simulating apparatus according to the first aspect of the present invention, a real ski is mounted, for example, a skier descends on a runway of a jumping platform and crosses at a crossing platform. According to a predetermined trajectory to fly, fall, and land on a landing slope, for example, the present invention relates to a moving screen or a ski and a skier including a slope and a landscape around the ski and the skier generated with the series of movements. In addition to controlling the state of air blowing, the left and right skis can be freely slid sideways on the mounting table by the lubrication member of the intermediate member, so you can enjoy the same excitement and exhilaration as the actual ski jump be able to.

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 simulated ski experience apparatus of the third aspect of the present invention, by using a stainless steel plate for the mounting base and using Teflon for the lubricating member, the coefficient of friction between the mounting base and the ski can be effectively reduced. And the sliding to the side can be facilitated.
