Abstract

PURPOSE:To apply both the motions of swinging and tilting for generating ambience, to a seat, with a single driving gear by setting the seat confronted with an image device, and by setting the driving gear for swaying the seat, with the sway axis of a straight line inclined downward against a horizontal line through the upper section of the seat. CONSTITUTION:When an operating instrument 4 is moved in the right direction, then an arm 12 is moved to the left side, and a base 1 is to be rotationally moved in the right direction watching the side of an image device 3 from a seat main-body 2, with the sway center of a straight line L. With the rotational movement of the base 1, the base 1 is tilted to the right, and accordingly, the seat main-body 2 and the image device 3 are to be tilted to the right. Besides, the base 1 is rotationally moved with the sway center of the tilted straight line L, and so the base is to be rotated with the swing axis of a vertical line through a space between the seat mainbody 2 and the image device 3. As this result, by the base 1, the synergy motion of tilting and swinging is to be generated. In this case, ambience is generated by the movement or the like of the centroid of an operator himself, but also from the change of the visual field of the operator, the ambience is to be generated.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a seat device used when viewing images showing changing scenery.

(Prior Art) Among this type of devices, devices in which the seat is rocked while viewing the image plane are already well known as play control devices.

Usually, this type of device is constructed by preparing a video device such as a CRT and a seat for the operator to sit on, and installing both on a common base.

By the way, in such a device, as the scenery projected on the image screen changes left and right, when moving the control tool left and right to follow the change, the image device and the seat should be moved left and right in the same way. If you make the turns in a certain direction, it will give you a sense of realism and you will be able to enjoy interesting simulated maneuvers.

(Problem to be Solved by the Invention) However, simply rotating the seat as described above does not provide the desired sense of realism. In order to create such a sense of realism, it is necessary to tilt the seat at the same time as the seat turns.

For example, if you turn to the right and tilt to the right at the same time, the two movements will be combined and you will feel as if you are turning to the right, creating a sense of realism. Become.

However, if we perform the above-mentioned turning and tilting at the same time,
A separate drive device for turning and a drive device for tilting are required. Therefore, each structure becomes complicated and the production cost is high.

The object of the present invention is to realize circular motion using a single driving device when turning and tilting a seat to create a sense of realism.

(Means for Solving the Problems) This invention includes a seat facing a video device, and the seat is swung around a straight line that is inclined downward with respect to a horizontal line passing through the upper part of the seat as the oscillation axis. It is characterized by being equipped with a drive device.

(Operation) When the seat is rotated, for example, to the right about the pivot axis, the seat tilts to the right and at the same time turns to the right about a vertical line passing through the seat. This allows the seat to simultaneously perform a tilting motion and a pivoting motion.

(Example) An example of the present invention will be described with reference to the drawings. 1 is the base,
The seat body 2 and the video device 3 are installed so as to face each other. 3A is a video screen of the video device 3.

A control tool 4 is provided in front of the seat body 2.

The image device 3 displays the external scenery seen from a moving vehicle, and may be a video image or a computer graphic image.

Reference numeral 5 denotes a fixed support frame that swingably supports the base 1. An upper portion of the seat body 2 is rotatably supported at one end of the support frame 5 by a shaft 6.

Further, at the other end of the support frame 5, a lower portion of the imaging device 3 is rotatably supported by a shaft 7.

That is, the base 1 is made swingable by both shafts 6 and 7.

As is clear from FIG. 2, the straight line passing through both shafts 6 and 7 is inclined downward with respect to the horizontal line passing through the support position of shaft 6.

Specifically, the straight line passing through both axes 6 and 7 is inclined forward and downward with respect to the horizontal line when viewed from the top of the seat body 2. A suitable angle of inclination is, for example, 10° to 45°. The base 1 swings about this straight line as the swing axis.

8 is a drive device for swinging the base 1, and the example shown in the figure is
A motor 10 installed on a fixed frame 9 fixed to the support frame 5, a crank arm 11 driven by the rotation of the motor 10, and an arm connecting the end of the crank arm 11 and the back surface of the base 1. 12.

The motor 10 rotates in conjunction with the operation of the control tool 4, selecting a rotation direction. According to this rotation, crank arm 1
1. The base 1 swings via the arm 12.

In the above configuration, when the control tool 4 is moved to the right, the arm 12 moves to the left and the base 1 swings about a straight line to the right when looking from the seat body 2 to the video device 3 side. It will start rotating in the direction.

The aforementioned rotation of the base 1 causes the base 1 to tilt to the right, thus causing the seat body 2. The imaging device 2 is now tilted to the right.

Furthermore, since the above-mentioned rotation of the base 1 is centered on the tilted straight line, the base 1 rotates around the vertical line passing between the seat body 2 and the image device 2 as the pivot axis. As a result of the above, the base 1 begins to perform a movement that is a combination of tilting and turning.

FIG. 3 shows the above state. Conversely, when the control tool 4 is operated to the left, the situation is as shown in FIG.

As understood from this explanation, the drive mechanism of the base 1 is
All that is needed is a device for swinging the base 1 about a straight line as the swing axis.

The above explanation is based on the movement of the pilot's own center of gravity.
This was a case where a sense of realism was created, but a sense of realism can also be felt from changes in the pilot's field of view.

Figure 5 is a side view of Figure 2 seen from the right side, especially the seat body 2.
Only the video device 3 is shown, and the solid line shows the case where the base 1 is in a horizontal state. Let M be the center line of the seat.

If the base 1 rotates to the right from this state, the seat body 2. The imaging device 2 moves to the position shown by the dotted line, and the center line M also moves. Let the center line after the movement be M'.

However, as described above, at this time, the seat body 2 and the like tilt to the right and at the same time turn in the same direction.

Therefore, the line passing through the axis 6 and perpendicular to the plane of the paper passes through the center of the image plane 3A of the image device 3 before the rotation, but after the rotation it moves to the left side of the image plane 3A. This means that the field of view on the right side is wider for the pilot.

This is a phenomenon similar to what happens when a vehicle turns to the right in an actual vehicle. This allows you to experience a sense of realism when turning.

In addition, in the embodiment shown in the figure, as shown in FIG.
Although the image device 3 is oscillated about a straight line in which the side is higher and the image device 3 side is lower, this height relationship may be reversed.

The above embodiment has a configuration in which the video device 3 and the seat body 2 are swingable, but instead of this, only the seat body 2 is made swingable and the video device 3 is fixed away from the base 1. You can leave it there. Furthermore, if necessary, the seat body 2 can be moved up and down,
Rotational motion or the like may also be added.

The control device described above is suitable for use in simulating the control of airplanes, ships, motorcycles, circuit vehicles, and the like. The present invention is also applicable to vehicles such as roller coasters, for example, when no steering tools are used.

(Effects of the Invention) As detailed above, according to the present invention, a drive device that tilts and rotates a seat used for video observation to create a sense of presence can be used as a drive device that swings the seat. Therefore, the drive mechanism can be significantly simplified.
