The display means 7 includes a scale 8 disposed at the measurement position P facing the experience zone E, and an upper plate. 3 and the intermediate plate 4 respectively fixedly provided separately, and and a pair of upper and lower laser pointer 9, 10 as a light emitting source that outputs a directional beam B toward the scale 8. In the first embodiment, as described later, the intermediate plate 4 and the lower plate 5 are integrally moved relative to the upper plate 3 in the left-right direction by vibration input. The lower laser pointer 10 of the display means 7 may be attached to either the intermediate plate 4 or the lower plate 5. When the lower plate 5 is moved relative to the intermediate plate 4 in the front-rear direction in addition to the relative movement in the left-right direction, the laser pointers 9 and 10 are provided on all the plates 3 to 5, and the left-right direction and the front-rear direction are provided. If the scale 8 is provided, it is possible to visually experience both left-right and front-back vibrations.

  In order to adjust the seismic isolation function of the seismic isolation test apparatus 1, an electromagnetic brake system 11 is provided as a braking means for suppressing relative displacement between the upper plate 3 and the intermediate plate 4. An operation unit 12 of the electromagnetic brake system 11 is provided in the experience zone E.

  The vibration test apparatus 1 is installed on the floor surface 13. This vibration test apparatus 1 not only generates vibration in a three-dimensional direction in accordance with actual earthquake vibration, but also generates lateral vibration along at least one of front, rear, left and right along the floor surface 13. A vibration generator (not shown) having a two-dimensional vibration generation function capable of being supported, and a pedestal that is supported by the vibration generator and covers the outside thereof and is vibrated laterally on the floor surface 13 by the vibration generator 14. On the pedestal 14 of the vibration test apparatus 1, the seismic isolation test apparatus 6 is mounted. The seismic isolation test device 6 mainly includes a steel upper plate 3, a steel intermediate plate 4, a steel lower plate 5, and a left-right direction provided between the upper plate 3 and the intermediate plate 4. A seismic isolation means 2, a longitudinal seismic isolation means 16 provided between the intermediate plate 4 and the lower plate 5, and a leg portion 15 for fixing and supporting the lower plate 5 on the pedestal 14 are provided.

And an eccentric roller 19 that rolls.

  The eccentric roller 19 is formed by integrating a large-diameter roller 19a and a small-diameter roller 19b whose rolling centers are eccentric to each other, and the large-diameter roller 19a contacts the upper rail 17 and moves on the upper rail 17 and the small-diameter roller 19b. Rolls on the lower rail 18 in contact with the lower rail 18. The eccentric roller 19 rolls between the rails 17 and 18 when the upper plate 3 and the intermediate plate 4 move relative to each other due to the eccentricity of the large-diameter roller 19a and the small-diameter roller 19b. When it is settled, it returns to the center of the lower rail 18 or the upper rail 17 and returns to the position of the plates 3 and 4 to exert the restoring action of stopping the rolling.

  The front-rear direction seismic isolation means 16 has the same configuration as the left-right direction seismic isolation means 2, and is provided between the intermediate plate 4 and the lower plate 5 in an arrangement orthogonal to the left-right direction seismic isolation means 2. In the first embodiment, the vibration input in only one of the front, rear, left and right directions, specifically the vibration input only in the left and right direction, is targeted. In such a case, the lower plate 5 and the front and rear direction are exempted. The vibration means 16 may be omitted, and the intermediate plate 4 may be fixedly supported on the vibration test apparatus 1 via the leg portion 15. In the illustrated three-layer seismic isolation test device 6, the longitudinal seismic isolation means 16 transmits the vibration acting on the lower plate 5 to the intermediate plate 4 as it is in response to the lateral vibration input. The plate 4 and the lower plate 5 vibrate integrally in the same mode. On the other hand, on the upper plate 3, a chair 20 with a seat belt on which an experienced person is seated is installed, and is set as a seismic isolation experience zone E.

  As shown in FIG. 2, the display means 7 is formed independently of the upper plate 3 and the lower plate 5 provided in the seismic isolation test device 6 and the floor surface 13 on which the vibration test device 1 is installed or the floor surface 13. In any case, it is provided between the vibration test apparatus 1 and the seismic isolation test apparatus 6 and the measurement position P that is vibration-insulated.

  The upper laser pointer 9 of the upper plate 3 and the lower laser pointer 10 of the lower plate 5 respectively hit the display panel 21 to indicate the respective scales on the scale 8 by the light beam B output from them. The lateral displacement positions of the lower plates 5 are individually shown.

  When not only the left and right direction seismic isolation means 2 but also the front and rear direction seismic isolation means 16 is caused to act by vibration generated by the vibration test apparatus 1, as described above, the laser pointers 9 and 10 are applied to all the plates 3 to 5. If the scale 8 for the left-right direction and the front-rear direction are provided, vibrations in the left-right direction and the front-rear direction can be visually experienced.

  In the first embodiment, the braking means is constituted by a known electromagnetic brake system 11. The electromagnetic brake system 11 is for the left and right direction seismic isolation means 2 that is fixed to the upper plate 3 along a surface in which the upper plate 3 and the intermediate plate 4 are relatively displaced with respect to each other, and is arranged close to the intermediate plate 4. The first electromagnet 22 and the intermediate plate 4 and the lower plate 5 are fixed to the lower plate 5 along the surfaces relatively displaced from each other, and are used for the longitudinal seismic isolation means 16 disposed close to the intermediate plate 4.

Brakes instantly. In the complete braking state, it becomes a non-seismic isolation state, and by gradually weakening the braking force or releasing the braking action, it becomes a seismic isolation state corresponding to them. The operation unit 12 is provided on the chair 20 in the experience zone E so that the experience person in the experience zone E can arbitrarily operate the operation unit 12.

  The operation of the seismic isolation experience facility according to the first embodiment will be described. When the experienced person experiences the seismic isolation action, the experienced person sits on the chair 20 in the experience zone E on the upper plate 3. When the experienced person is seated, the pair of upper and lower laser pointers 9 and 10 are caused to emit light and the vibration test apparatus 1 is activated. Thereby, the base 14 of the vibration test apparatus 1 vibrates in the left-right direction. In a state where the power supply 24 of the electromagnetic brake system 11 is OFF, the electromagnetic brake system 11 does not operate, and the seismic isolation test device 6 exhibits a seismic isolation function.

  Due to the seismic isolation action, the upper plate 3 is isolated from the lower plate 5 and the intermediate plate 4 that vibrate in the left-right direction due to the vibration of the vibration test apparatus 1 and gently shakes. In this state, the experience person sees a state in which the light beam B from the pair of upper and lower laser pointers 9 and 10 of the lower plate 5 and the upper plate 3 moves on each scale of the scale 8 of the display panel 21 from the experience zone E. You can know. In this case, the light beam B of the upper laser pointer 9 swings to the left and right greatly compared to the light beam B of the lower laser pointer 10 that moves in the horizontal direction. The amount of shaking is visually and objectively displayed on the scale 8. In FIG. 2B, the vibration displacement of the upper plate 3 is shown as “seismic isolation”, and the vibration displacement of the lower plate 5 is shown as “non-seismic isolation”.

  When the experience person switches the power supply 24 of the electromagnetic brake system 11 to ON using the operation unit 12, the braking action of the electromagnetic brake system 11 can be activated, and the magnetic force of the first electromagnet 22 is operated by operating the transformer 25. By adjusting the increase / decrease, it is possible to change the braking force that brakes the relative movement between the upper plate 3 and the intermediate plate 4, thereby adjusting the attenuation of the seismic isolation action. When fully braked, it becomes non-seismic. In the non-base-isolated state, the instructions on the scale 8 of the upper and lower laser pointers 9 and 10 are the same, and the experienced person feels the shaking in the non-base-isolated state in the experience zone E, and the amount of shaking is visually and objectively.

The display means 7 is arranged at the measurement position P facing the experience zone E, and the upper plate 3 and the intermediate plate 4 or the lower part. Each plate 5 is individually fixed and provided with a pair of upper and lower laser pointers 9 and 10 that output a directional light beam B toward the scale 8. A common index that is easy to understand visually or bodily by applying the light beam B from the laser pointers 9 and 10 to the scale 8 indicating the displacement position. Can be perceived at the reference or the like, in experience seismic isolation effect, in addition to the viewer individual susceptibility, it is possible to objectively understand its experience.

  Moreover, since the electromagnetic brake system 11 for suppressing the relative displacement between the intermediate plate 4 and the upper plate 3 is provided, the seismic isolation function of the seismic isolation test device 6 is adjusted to change from a non-isolated state to a complete seismic isolation state. Can be experienced by the experienced person, and the seismic isolation effect can be accurately recognized by the experienced person. Further, since the braking action is obtained by adjusting the magnetic force of the electromagnetic brake system 11, the seismic isolation action of the seismic isolation test device 6 can be variably changed. Because the operation section 12 of the electromagnetic brake system 11 is provided in the experience zone E, it is possible for the experience person to adjust seismic isolation / non-isolation arbitrarily at their own will, making it an excellent experience facility and ensuring safety can do.

  FIG. 3 shows a modification of the first embodiment. In this modification, a known disc brake system 26 is employed as a braking means instead of the electromagnetic brake system 11. In the disc brake system 26, the disc 27 provided on the guide roller portion 19b is clamped by a caliper 28 installed on the upper rail 17, and the hydraulic pressure supply for operating the caliper 28 is supplied to the experience zone E. The operation is performed via a hydraulic pressure supply system 30 by depressing a brake pedal 29 as an operation unit provided. Even with such a disc brake system 26, the same operation and effect as the electromagnetic brake system 11 can be obtained. Even in such a modification, the same operation and effect as in the first embodiment can be obtained. Obtainable.

When the experienced person experiences the seismic isolation action, the experienced person sits on the chair 20 in the experience zone E on the upper plate 3. When the experienced person is seated, the vibration test apparatus 1 is activated. Thereby, the base 14 of the vibration test apparatus 1 vibrates in the left-right direction. In a state where the power supply 24 of the electromagnetic brake system 11 is OFF, the electromagnetic brake system 11 does not operate, and the seismic isolation test device 6 exhibits a seismic isolation function.

  Due to the seismic isolation action, the upper plate 3 is isolated from the lower plate 5 and the intermediate plate 4 that vibrate in the left-right direction due to the vibration of the vibration test apparatus 1 and gently shakes. This state can be known by seeing the movement state of the indicator needle 31 that moves on the scale of the scale 8 from the experience zone E through the transparent upper plate 3 by the experience person. In this case, the amount of displacement of the indicator needle 31 with respect to the mark 32 is displayed on the scale of the scale 8 visually and objectively, in addition to the bodily sway received on the upper plate 3. .

  FIG. 6 shows a third embodiment of the seismic isolation experience facility according to the present invention. This third embodiment basically includes an upper plate as two upper and lower layers that are displaced relative to each other via a vibration test apparatus 1 that generates lateral vibration and a left and right direction seismic isolation means 2 as a seismic isolation means. 3 and an intermediate plate 4, the intermediate plate 4 is attached to the vibration test apparatus 1 via the lower plate 5, and the seismic isolation test apparatus 6 in which the upper plate 3 is the experience zone E, and the vibration test apparatus. 1 is provided at a measurement position P that is vibration-insulated from 1, and includes a display means 7 for displaying the displacement of the upper plate 3. The measurement position P is set in a displacement area of the experience zone E. The movable displacement position indicating members 33 are arranged in multiple stages in accordance with the magnitude of the displacement in the displacement region.

  The third embodiment has features in the measurement position P and the display means 7 with respect to the first and second embodiments. In the third embodiment, the measurement position P that is vibration-insulated from the vibration test apparatus 1 is a space above the upper plate 3.

In the state where the braking means is released, the seismic isolation test device 6 exhibits the seismic isolation function. Due to the seismic isolation action, the upper plate 3 is isolated from the lower plate 5 and the intermediate plate 3 that vibrate in the left-right direction due to the vibration of the vibration test apparatus 1 and gently shakes. This state can be known by seeing the distance between the displacement position indicating member 33 and the rod-shaped member 35 or feeling contact. In this case, due to a sense of distance from the displacement position indicating member 33, the amount of displacement is visually and objectively displayed to the experience person in addition to the bodily sway received on the upper plate 3.

Provided, the measurement position P is set in the displacement region of the experience zone E, and the display means 7 is movable in a displacement region indicating member 33 arranged in multiple stages in the displacement region of the experience zone E according to the magnitude of the displacement. Therefore, the seismic isolation experience not only depends on the actual feeling of the experiencer, but also can be perceived with the common indicators and standards that are easy to understand visually or physically by the displacement position indicating member 33 that indicates the displacement position. During the experience of seismic isolation, it is possible to objectively understand the experience in addition to the individual sensitivity of the experience.

  Further, in the third embodiment, since the rod-shaped material 35 is simply disposed above the upper plate 3 by the suspension material 34, it can be configured inexpensively and easily. In the third embodiment, the upper plate 3 may be vibrated two-dimensionally by causing the longitudinal seismic isolation means 16 to function. Even in the third embodiment, it is a matter of course that the same operations and effects as those in the first and second embodiments can be obtained.
