Vertical vibration frame 3,

As the configuration that flows in the vertical direction by the vertical vibration means (2),

As shown in Figures 1 to 3,

The lower surface is mounted on each vertical eccentric cam 22 of the vertical vibration means 2, and a plurality of ball bearings 33 are provided at the upper edge, and the guide 11 of the base frame 1 is provided at the lower edge. A plurality of rollers 31 which are raised and lowered along the inner side thereof are provided, and are vertically moved by the vertical vibration means 2.

In addition, the vertical vibration frame 3 is generally composed of an outer frame having a rectangular frame shape and an inner frame interconnecting the outer frame, and may be formed in various shapes other than the rectangular frame as necessary.

The roller part 31,

As shown in FIG. 3 and FIG. 5,

A fixing bracket 311 fixedly installed at a lower edge of the vertical vibration frame 3;

A flow bracket 312 connected to be movable in a horizontal direction toward the inside of the guide 11 at a lower end of the fixing bracket 311;

A roller 314 rotatably coupled to an end of the flow bracket 312 so as to be lifted while contacting an inner surface of the guide 11;

It is coupled between the fixing bracket 311 and the flow bracket 312 and the pressure between the roller 314 and the guide 11 is constant while elastically flowing along the front and rear direction by the movement of the vertical vibration frame (3) A spring 313 to adjust;

Is done.

In other words, as shown in Figure 5,

The fixing bracket 311 is

A pair consisting of a plate shape is coupled in the vertical direction, the upper end is fixedly coupled to the lower edge of the vertical vibration frame (3), the lower end is formed with a front opening guide groove (3112) in the form of a long hole (長 孔) It consists of a fixing piece 3111 and a connecting piece 3113 connecting each of the fixing pieces 3111.

The front end of the spring 313 is supported on the rear surface of the body portion 3122 of the flow bracket 312, and the rear end of the spring 313 is fixed. The bracket 311 is disposed to be supported on the front surface of the connecting piece 3113.

Of course, the roller 314 is coupled to the roller fixing part 3121.

Looking at the operation of the roller portion 31,

When the vertical vibration frame 3 is moved up and down by the rotation of the vertical eccentric cam 22, the roller 314 provided in the vertical vibration frame 3 is the guide 11 of the base frame 1. It is raised and lowered in contact with the inside of the).

According to this, the vertical vibration frame (3) flowing in the vertical direction can be more easily flow, even if the pressure is transmitted in the horizontal direction to the vertical vibration frame (3) in some cases to the inside of each guide (11) Since the rollers 314 are disposed to be in contact with each other, the vertical vibration frame 3 is prevented from flowing in the horizontal direction.

Further, since the vertical vibration frame 3 is prevented from flowing in the horizontal direction, the vertical eccentric cam 22 and the vertical vibration frame 3 naturally also serve to guide the friction in the horizontal direction.

At this time, the inner side of the guide 11 in which the roller 314 is in contact is provided with a buffer member of an elastic material to guide the roller 314 and the guide 11 made of a metal material to correspond more smoothly.

And on the upper side of the vertical eccentric cam 22,

The upper hinge portion 341 is

The upper coupling member 3411 fixedly coupled to the lower portion of the vertical vibration frame 3, the coupling hole 3413, which is coupled to the lower portion of the upper coupling member 3411, into which the hinge shaft 343 is inserted. The upper connection member 3412 is formed.

Lower hinge portion 342,

The lower coupling member 341 and the upper coupling member 3412 which are in surface contact with the upper end of the eccentric cam 22 are coupled to the upper portion of the lower coupling member 341, and the hinge shaft 343 is inserted and the upper connection member 3412 is fitted. The ball 3413 and the corresponding fitting hole 3423 are formed of two or more lower connection members 3422 formed therethrough.

On the other hand, when there is no configuration of the hinge portion 34 as in the present invention,

Each of the vertical eccentric cams 22 is different from each other in the time of lifting and lowering.

Therefore, when the vertical vibration frame 3 is rotated, the vertical vibration frame 3 and the vertical eccentric cam 22 do not have a constant surface contact with each other, but are in contact with the edge of the upper surface of the vertical eccentric cam 22. If the irregular lifting operation is repeated, the irregular lifting operation is repeated, the vertical eccentric cam 22 may be deformed or the deformation of the drive shaft, and eventually effective earthquake experience is impossible.

However, according to the configuration of the hinge portion 34 as in the present invention,

As shown in FIG.

Even when the upper hinge portion 341 rotates, the lower hinge portion 342 is non-rotating and is always in surface contact with the vertical eccentric cam 22 within a predetermined range.

Therefore, according to the present invention, the vertical eccentric cam 22 can lift the vertical vibration frame 3 stably due to the configuration of the hinge part 34.

Is made of.

Meanwhile, the inner cam 421 of the horizontal eccentric cam 42 may further include a cover 424 covering the front portion of the inner cam 421 similarly to the vertical eccentric cam 22. The front portion and the cover 424 of the inner cam 421 is coupled using.

Horizontal vibration frame 5,

As the configuration in which the horizontal vibration means (4) flows in the front and rear, left and right horizontal direction,

As shown in Figures 1 to 3,

The lower surface is placed in contact with the ball bearing 33 of the vertical vibration frame 3, the center of the coupling bracket 51 is rotatably coupled to the horizontal eccentric cam 42 of the horizontal vibration means (4) It is made to be provided (see Fig. 2), the horizontal vibration means (4) is to flow in the horizontal direction.

At this time, the horizontal eccentric cam 42 and the coupling bracket 51 may be fixedly coupled in a variety of ways, such as mutually bolted.

In addition, the horizontal vibration frame 5 is generally composed of an outer frame having a rectangular frame shape and an inner frame interconnecting the outer frame, and may be formed in various shapes other than the rectangular frame as necessary.

When the inner cam 421 is rotated by the drive unit 41, the inner cam 421 rotates eccentrically based on the drive shaft of the drive motor 411.

That is, when viewed in a plane is rotated by drawing a certain circle around the drive shaft of the drive motor 411 (see Fig. 9), the horizontal vibration frame 5 combined with the horizontal eccentric cam 42 in the horizontal direction Will be rotated along.

On the other hand, the upper side of the horizontal vibration frame 5 is configured to further include a footrest plate 6 and a chair 7 for the experience subject.

Looking at the operating method of the present invention with reference to Figures 7 and 9,

When the driving unit 21 of the vertical vibration means 2 fixed to the base frame 1 is operated, the vertical eccentric cam 22 connected to the driving unit 21 is eccentrically rotated.

Then, as shown in FIG. 7, the vertical vibration frame 3 flows in the vertical direction by the vertical eccentric cam 22.

However, since each of the vertical eccentric cams 22 is different from each other during the rotation, the four points of the vertical vibration frame 3 are different from each other.

Therefore, rather than a simple vibration in the vertical direction occurs three-dimensional vibration in the up and down, it is possible to enable the experienced subjects more efficient learning.

On the other hand, when the driving unit 41 of the horizontal vibration means (4) fixed to the horizontal vibration frame (5) while operating the vertical vibration means (2), the horizontal eccentric cam (42) connected to the drive unit 41 also Eccentric rotation.

Then, the horizontal vibration frame (5) by the horizontal eccentric cam 42 is to flow in the horizontal direction front and rear, left and right.

At this time, the horizontal vibration frame 5, by the ball bearing 33 in contact with the lower surface it is possible to easily rotate in the horizontal direction while maintaining a constant interval with the vertical vibration frame (3).

In general, the conventional earthquake experience device, because it simply vibrates in the horizontal direction or up and down direction, it is difficult to reproduce the earthquake of various patterns. By occurring, there is a problem that the experienced subjects have difficulty in effective earthquake experience.

However, the present invention allows the subjects to experience various earthquake occurrences at the same time through the above operation, and can be used for a long time without malfunction or breakage of parts, and it is easy to replace parts to have an effective earthquake experience.
