BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shaking mechanism for a simulated experience game device that provides a realistic experience to the audience by moving the audience seats in various ways in accordance with, for example, images and sounds.

0002

[Prior Art] As a simulated experience game device that combines images and sounds to provide a realistic simulated experience, there are devices that shake the seats, and seats that rotate while moving like a coffee cup at an amusement park. something is known.

0003

[Problems to be Solved by the Invention] However, it is difficult to make people experience large movements by shaking alone, and it is not suitable for a large-scale device in which screens are arranged around the entire circumference of the audience seats. On the other hand, it was not possible to fully experience the movement in accordance with the video by only moving and rotating.

[0004] On the other hand, a more realistic experience can be brought about by moving the swing table on which the audience seats are installed, moving it up and down, and swinging it back and forth and left and right.

However, in this case, it is conceivable to arrange the cylinder that drives the shaking table perpendicularly to the bottom surface of the shaking table, but in this way, the necessary minimum height of the shaking table is determined from the relationship with the length of the swinging cylinder. Therefore, the minimum height is regulated by the swing cylinder, and in particular, if the maximum inclination angle of the swing table is increased, the required stroke of the swing cylinder becomes longer, and the overall height becomes higher.

[0006] For this reason, depending on the setting of the maximum inclination angle of the swinging table, the overall size of the apparatus cannot be avoided, and the length of the swinging cylinder causes problems in terms of space for its arrangement, buckling strength, etc.

[0007] The present invention provides a swinging mechanism in which the required stroke of the swinging cylinder is small, the center of swing is lowered, and stability during swinging and miniaturization can be achieved even though the maximum inclination angle of the swinging table can be large. The purpose is to

[0008]

[Means for Solving the Problems] The present invention supports a swinging table via a center post located at the center of the lower surface, and is structured so that the swinging table can be moved back and forth and left and right by at least two swinging cylinders. , in a swinging mechanism in which a swinging table is connected to a steady rest link for preventing rotation, a swinging cylinder is installed at an angle with respect to the center post, and a connection point of the swinging cylinder to the swinging table is installed at a horizontal position of the swinging table. was set to be located above the center post's oscillating table support point.

[0009]

[Operation] The connection point of the swing cylinder to the swing table is raised higher than the support point of the center post, so when the swing cylinder is contracted and the swing table is tilted, the extension of the axis of the swing cylinder is The inclination angle of the swing table can be increased until it reaches the dead point passing through the support point.

In this case, by bringing the connection point of the swing cylinder close to the center of oscillation of the oscillation table, the effective stroke of the swing cylinder required to obtain the same tilt angle can be shortened, and the swing cylinder can be tilted. Together with this, the space required in the vertical direction on the lower surface of the shaking table can be reduced, and the swinging fulcrum of the shaking table can be significantly lowered.

Embodiments) Examples of the present invention are shown in FIGS. 1 to 5.

As shown in FIG. 1, the base 1 is an annular frame made of a steel frame or the like, and has a number of wheels 4 on the bottom surface as shown in FIG. A guide rail 3 is laid on the floor 2 in a circular manner.

The inner circumferential portion of the base 1 is provided with a moving means as shown in FIG.
And as shown in FIG. 3, six hydraulic motors 7 with sprockets 6 attached are fixed. A chain 8 that engages with this sprocket 6 is arranged on the floor surface 2 so as to form a concentric circle inside the guide rail 3, and the base 1 rotates as the sprocket 6 engages with the chain 8.
Move along the guide rail 3.

The base 1 also includes a telescoping lock cylinder 18. When this lock cylinder 18 expands, its tip enters the engagement hole in the floor surface 2 and locks the movement of the base 1, while when it contracts, it pulls the tip up from the engagement hole to release the lock.

On the base 1, circular swing tables 5 equipped with spectator seats (not shown) are arranged at three equal intervals. As shown in FIG. 2, the shaking table 5 is rotatably supported on a turntable 9, and a center post 11 is connected to the center of the turntable 9 via a universal joint 10.
are combined. The center post 11 has its base end fixed to the base 1, and expands and contracts together with the expansion and contraction of a lifting cylinder 12 serving as a lifting means, thereby raising and lowering the turntable 9 together with the swing table 5.

On the lower surface of the turntable 9, two swing cylinders 13A, 13B and one steady link 14 are provided as means for swinging the swing table 5, one end of which is supported by the base 1. are connected from different directions.

The two swing cylinders 13A and 13B expand and contract together or individually to move the turntable 9.
is swung back and forth and left and right together with the swing table 5 supported thereon. The steady rest link 14 prevents the horizontal rotation of the turntable 9 while guiding its rocking displacement.

As is clear from FIG. 2, the swing cylinder 1
3A and 13B are installed at an angle with respect to the vertical center post 11, which makes it possible to lower the oscillation surface of the oscillation table 5 compared to a case where it is installed vertically, thereby ensuring stability of the oscillation motion. do.

Further, as is clear from FIG. 1, the extensions of the axes of the two swing cylinders 13A and 13B are arranged so that they intersect with each other at the axis on the plane of the center post 11. Steady rest link 14
They intersect at the same angle to the line connecting them.

In this way, the swing cylinders 13A, 1
3B's axes intersect at the center of the center post 11, when the swing cylinders 13A, 13B are expanded and contracted, the rotational moment acting on the swing table 5 around the center post 11 is reduced, and the rotational moment about the center post 11 is reduced. , it is possible to reduce the bending force acting on the steady rest link 14 due to the rocking movement from side to side.

By the way, these swing cylinders 13A, 1
The connection point of 3B to the swing table 5 is set at a position higher than the swing support point of the universal joint 10 of the center post 11 when the swing table 5 is in a horizontal state, as shown in FIG.

As a result, when the swinging cylinders 13A, 13B are contracted and the swinging table 5 is tilted, the connecting points of the swinging cylinders 13A, 13B to the swinging table 5, the connecting point to the base 1, and the center post 11 are The linkage formed by the swing support point can increase the maximum angle at which the swing table 5 can tilt before reaching the dead point. When tilting the oscillating table 5, the extension of the axes of the oscillating cylinders 13A and 13B becomes the center post 1.
The dead point is when the swinging cylinders 13A and 13B pass through the center of swinging.
The angle of inclination deepens further without returning to horizontal.

Therefore, the maximum inclination angle is the angle allowed in the range up to the dead point.
By increasing the connection point of the swing cylinders 13A, 13B to the swing table 5, this maximum inclination angle can be increased.

At the same time, when the connection point of the swing cylinders 13A, 13B is brought closer to the swing center of the center post 11, the swing cylinders 13A, 13 necessary to obtain the maximum inclination angle are
The effective stroke of B becomes correspondingly smaller. As a result,
Coupled with the inclined arrangement of the swing cylinders 13A and 13B, the swing cylinders 13 on the lower surface of the swing table 5
The height required to accommodate A and 13B is reduced, and the center of oscillation of the oscillating table 5 is lowered accordingly, making it possible to stabilize the oscillating motion and lower the overall height of the device.

As shown in FIG. 4, four hydraulic motors 15 are installed on the outer periphery of the turntable 9 as means for rotating the shaking table 5.
will be placed. As shown in FIG. 5, a gear 16 is attached to the rotating shaft of each hydraulic motor 15, and an internal gear 17 that meshes with the gear 16 is formed on the swing table 5 facing the outer periphery of the turntable 9.

The turntable 9 also includes a telescoping lock cylinder 19. When the lock cylinder 19 is expanded, its tip enters an engagement hole formed in the swing table 5 to lock the relative rotation between the swing table 5 and the turntable 9, and when it contracts, this lock is released.

As shown in FIG. 2, the base 1 is provided with four telescoping storage posts 20 below the swing table 5. This storage post 20 is normally retracted to a position where it does not interfere with the movement of the swing table 5, and the storage post 20 is
When necessary, such as during maintenance, the tip is extended to horizontally support the swing table 5.

The supply of hydraulic pressure to the hydraulic motors 7 and 15, the lifting cylinder 12, the swing cylinders 13A and 13B, and the lock cylinders 18 and 19 are all controlled by a controller (not shown), and these are controlled by a separately provided video device. is driven in sync with the

Next, the operation will be explained.

The shaking table 5 performs the following various operations under the control of the controller.

That is, when the swing cylinders 13A and 13B are extended and contracted together with the lifting cylinder 12 stopped, the turntable 9 moves along with the swing table 5 using the universal joint 10 as a fulcrum, and moves the steady rest link 14.
While bending and stretching, it oscillates as shown by the imaginary line in FIG. 2, and this movement becomes a back-and-forth rocking movement (tangential direction) along the guide rail 3 in FIG. 1, that is, a pitching movement.

Furthermore, when the swing cylinders 13A and 13B are driven to expand and contract alternately, the turntable 9 similarly swings from side to side with respect to the direction of movement in FIG. wake up

Furthermore, when the elevating cylinder 12 and the swinging cylinders 13A and 13B are expanded and contracted synchronously, the turntable 9 moves up and down together with the swing table 5, that is, performs a heaving motion.

When it is desired to rotate the swing table 5, the lock cylinder 19 is released and the hydraulic motor 15 provided on the turntable 9 is operated. As a result, the gear 16 attached to the rotating shaft of the hydraulic motor 15 rotates while meshing with the internal gear 17 formed on the shaking table 5, causing the shaking table 5 to rotate.

Furthermore, when it is desired to move the swing table 5, the lock cylinder 18 is released and the hydraulic motor 7 is operated. As a result, the sprocket 6 fixed to the rotating shaft of the hydraulic motor 7 rotates while meshing with the chain 8 disposed on the floor 2, the wheels 4 roll on the guide rail 3, and the base 1 rotates. Accordingly, the shaking table 5 moves in an arc.

In this manner, the swing table 5 can perform various movements under the control of the controller. Note that it is of course possible to combine a plurality of exercises.

As described above, the swing cylinders 13A and 13B for swinging the swing table 5 have their connection points to the swing table 5 at a higher position than the support point of the center post 11, so the swing cylinders 13A and 13B swing the swing table 5. , 13B are contracted to tilt the shaking table 5, the angle of inclination until reaching the dead point can be increased, and at this time, the connecting point of the shaking table 5 of the swinging cylinders 13A, 13B is connected to the support point. By bringing the swing cylinders 13A, 13B closer together, the required stroke of the swing cylinders 13A, 13B required to tilt the swing table 5 by a predetermined angle is shortened.
13B is disposed obliquely on the lower surface of the shaking table 5, so the storage space required for the swinging cylinders 13A, 13B below the shaking table 5 is reduced in the vertical direction, and as a result, the shaking surface of the shaking table 5 is This makes it possible to provide stable rocking motion and reduce the overall height of the device to make it more compact.

[0038]

As described above, the present invention mounts the swing cylinder at an angle to the center post, and connects the connection point of the swing cylinder to the swing base at the horizontal position of the swing base. Since it is set to be located above the support point of the oscillation table, when the oscillation cylinder is contracted and the oscillation table is tilted, the axis of the oscillation cylinder extends until it reaches a dead point passing through the support point. The inclination angle of the oscillating table can be increased, increasing the degree of freedom in controlling the inclination angle of the oscillating table. The effective stroke of the rocking cylinder required to move the rocker can be shortened, and together with the tilted arrangement of the rocking cylinder, the vertical storage space required for the rocking cylinder on the underside of the rocking table is reduced. As a result, it becomes possible to significantly lower the oscillation fulcrum, thereby stabilizing the oscillation motion of the oscillation table and reducing the overall height of the entire device.
