Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a simulated experience device for leisure and training, and more particularly to a shaking mechanism provided in a simulated experiment device.

[0002]

[Prior Art]

 Some of the simulated experience devices provided in leisure facilities, etc., shake the shaking table on which the passengers are on board in accordance with the image and sound in order to realistically reproduce the speed and thrill of various vehicles.

The shaking table is adapted to perform, for example, vertical movement (heaving), horizontal axis rotation (pitching), longitudinal axis rotation (rolling), and vertical axis rotation (yawing). .

[0004]

[Challenges for devising]

 However, the mechanism that causes these shaking motions on the shaking table generally has a complicated structure using a large number of links, and there is a problem in that the equipment costs a lot.

The present invention has been made to solve such a problem, and an object thereof is to provide a simple rocking mechanism capable of performing heaving, pitching, rolling, and yawing operations.

[0006]

[Means for achieving the object]

 The present invention comprises a center guide for guiding the center of the rocking body in the vertical direction, three telescopic cylinders for supporting the rocking body at each vertex of an isosceles triangle having vertices on the orthogonal center lines of the rocking body, and the rocking body. It is provided with a yawing dynamic telescopic cylinder that rotationally displaces the body around a vertical axis.

[0007]

[Action]

 When the three telescopic cylinders are telescopically extended and contracted, the oscillating body is heaved.

Of the three telescopic cylinders, the telescopic cylinder that supports the intersection of the equilateral sides of the isosceles triangle is expanded and contracted, and the other two telescopic cylinders are held in a stopped state, whereby the rocking body is pitched.

Further, by holding the telescopic cylinder supporting the intersection of the equilateral sides of the isosceles triangle in a stopped state and telescopically extending the other two telescopic cylinders in opposite phases, the oscillating body rolls.

In these operations, the expanding / contracting cylinder for yawing motion expands and contracts following the movement of the oscillating body.

Further, when the expansion / contraction cylinder for yawing operation is expanded / contracted while holding the three expansion / contraction cylinders in a stopped state, the rocking body yaws.

【Example】

 1 to 3 show an embodiment of the present invention.

In FIG. 1, a disk-shaped rocking base 1 is connected to a center guide 2 which is erected on a floor 7 through a spherical bearing 2A, and its upper end is inclined toward the center. It is supported by cylinders 3-5 and a telescopic cylinder 6 for yawing operation.

As shown in FIG. 2, the center guide 2 has a rod 10 that is coupled to a spherical bearing 2A and is slidably inserted into a guide body 11 fixed to a floor 7, whereby the spherical bearing 2A is vertically supported. Supports expansion and contraction in any direction.

The telescopic cylinders 3 to 5 are connected at their upper ends to the shaking table 1 and at their lower ends to the floorboard 7, respectively. The joint between the telescopic cylinder 3 and the rocking base 1 is located on the center line of the rocking base 1, and the joint between the telescopic cylinders 4 and 5 and the rocking base 1 is on another center line orthogonal to this center line. Located at the same distance from the center of 1. That is, these joints form an isosceles triangle, and the center of the shaking table 1 is located on the midline thereof.

The lower ends of the telescopic cylinders 3 to 5 are connected to the floor board 7 outside the upper ends, respectively. These connecting positions are set such that the vertical axis passing through the center of the oscillator 1 and the telescopic cylinders 3 to 5 are on the same vertical plane.

As shown in FIG. 3, the telescopic cylinder 6 for the yawing operation is arranged on the opposite side with the telescopic cylinder 3 and the center guide 2 interposed therebetween. The upper end of the telescopic cylinder 6 is connected to the rocking base 1 on the extension of the median line of the above-mentioned isosceles triangle. On the other hand, the lower end is connected to the floorboard 7 at a position laterally displaced from the vertical plane including the above-mentioned midline so that the central axis of the telescopic cylinder 6 is offset by the distance L from the center of the shaking table 1.

It should be noted that spherical bearings are used for the connecting portions of the telescopic cylinders 3 to 6 with the rocking table 1 and the floor 7, respectively.

Next, the operation will be described.

Heaving of the rocking table 1 is performed by driving the three telescopic cylinders 3 to 5 to synchronously extend and contract, and the telescopic cylinder 6 is expanded and contracted following the heaving. With this heaving operation, the center guide 2 expands and contracts.

When rolling the rocking base 1, the telescopic cylinder 3 is held in a stopped state and the telescopic cylinders 4 and 5 are telescopically extended in opposite phases. As a result, the oscillating base 1 oscillates in the left-right direction in FIG. 2 about the horizontal axis X passing through the joint with the center guide 2. The expansion / contraction cylinder 6 expands / contracts following this rolling operation.

When the rocking table 1 is pitched, the telescopic cylinders 4 and 5 are held in a stopped state, and the telescopic cylinder 3 is telescoped. As a result, the rocking table 1 rocks in the left-right direction in FIG. 3 about the horizontal axis Y shown in FIG. The telescopic cylinder 6 follows the pitching operation to expand and contract.

Further, when the rocking base 1 is yawed, the telescopic cylinders 3 to 5 are held in a stopped state and the telescopic cylinder 6 is telescopically extended. As a result, the oscillating table 1 is rotationally displaced about the vertical axis. In this way, the oscillating table 1 can perform heaving, rolling, pitching, and yawing operations with simple operations.

The center guide 2 does not expand and contract during rolling, pitching and yawing operations, but expands and contracts only during heaving operations. Since the lateral displacement of the oscillating table 1 is restricted in any operation, there is no possibility that the oscillating table 1 will perform an unintended operation.

It is also possible to arrange the telescopic cylinders 3 to 5 vertically without inclining them.

[0026]

[Effect of the device]

 As described above, according to the present invention, the rocking table is supported by the three telescopic cylinders, the center guide and the telescopic cylinder for rotation, so that the heaving, rolling, pitching and yawing operations can be performed on the rocking table with a simple structure. Can be done.

Therefore, the cost of the simulated experience device can be reduced by applying the present invention.
