Description

Pody theater chair

The present invention relates to a podi theater chair that provides a three-degree of freedom movement according to a stereoscopic image of a large screen, and more specifically, to implement a three-degree of freedom operation by a plurality of three actuators installed in parallel in a plurality of chairs, The present invention relates to a podi theater chair that provides a high degree of satisfaction while minimizing the installation and maintenance costs of the device because it provides a plurality of chairs to perform the same exercise independently and.

In general, a simulator is not a reality but realizes a situation that is almost realistic, and is composed of a video device, a control device, a motion device, and a control device.

In the above, the exercise device and the control device are referred to as a separate motion base (or motion platform). Recently, the exercise device and the control device have been actively applied in various fields such as theaters displaying stereoscopic images in addition to games and driving simulations.

In particular, as the popularity of theaters showing three-dimensional images has soared, a number of Fordy theater chairs have been developed that provide three-degree-of-freedom movements according to three-dimensional images on a large screen.

These pody theater chairs are equipped with an actuator that moves up and down in three positions below the chair, and the chair rolls, pitches, yaws, and heaves while moving up and down regularly. The three-dimensional motion is generated by moving in the sway and surge directions.

However, in the conventional Podi theater chairs, the whole chair is moved up and down by the actuator at three positions of the lower left and right sides of the chairs installed in parallel, so that the movement of the person seated in the chair at the center and the chair at both ends is felt. There was a problem with the difference.

That is, since the whole chair is moved up and down by the actuator in three positions of the lower side of the chair installed in a plurality of parallel left and right, there is a problem that can not give the same movement force as a whole chair.

In addition, since the load applied to each actuator is large, there is a problem that the durability of the device is also significantly reduced.

In order to improve this, the multiple chairs are separated from each other so that each chair can move up and down by the actuator at three lower positions, so that the multiple chairs have the same movement force, but this is because the actuators are installed in three positions for each chair and control them. Since the I / O capacity of the host computer is largely required, there is a problem in that the installation and maintenance of the device is expensive.
