Description

  The present invention relates to a display method and apparatus for protecting fragile exhibits such as ceramics and glass crafts of high historical, cultural, artistic and economic value from earthquakes. The present invention relates to an exhibition method and apparatus for effectively protecting exhibits made up of a plurality of objects such as appendages from earthquakes.

  If an article is placed on a display shelf, display shelf, display stand, etc. because it is easily destroyed as described above, if an earthquake occurs, the display shelf, display shelf, display stand, etc. may fall or fall due to vibration. There is a high risk of precious ceramics and glass crafts being damaged or damaged. In particular, when an exhibit is separated into a plurality of pieces in the vertical direction, such as a lidded container, when it is dropped and received, there is a possibility that it will be damaged due to a collision between components of the exhibit.

  For this reason, conventionally, a string or the like is stretched around a decoration shelf or a display shelf decoration, or a support bar or the like is provided to prevent the fall or fall. In the case of a particularly large decorative article, a plurality of strings are stretched at a predetermined interval. However, such a method is not only uncertain as a means of preventing a fall or fall, but is also unsightly in appearance, detracts from historical and cultural significance, and often prevents artistic appreciation.

  In order to solve these problems, when displaying arts and crafts, etc., it is possible to display arts and crafts as they are without obstructing the appreciation, and to avoid damage caused by vibrations such as earthquakes. For this purpose, an instrument mounting table with an anti-vibration protection function has been proposed (for example, see Patent Document 1). This is because a ceramic product is placed, a thin plate that supports the ceramic product to be placed, a seismic motion detector that detects vibration of the thin plate, and a detection signal from this seismic motion detector supports the ceramic product by the thin plate. And a base box which is disposed below the thin plate and accommodates and protects the ceramic product 4 falling from the thin plate by releasing the support of the ceramic product by the thin plate.

As another conventional technique, there has been proposed a protection device for an exhibit that prevents the exhibit from falling over and being damaged by an earthquake or the like (see, for example, Patent Document 2).
The mechanism of the protection device for the exhibit exhibits a retractable protective member disposed around the upper plate on which the exhibit is placed. When the detector detects a shake exceeding a predetermined level due to an earthquake or the like, the protective member extends by the high-pressure gas supplied from the high-pressure gas supply source through the pipe and surrounds the periphery of the exhibit. Then, the exhibits that are about to fall are received and their damage is prevented.

  As another conventional technique, a support base having a predetermined height is provided so that a pair of openings are opposed to the top and the bottom, and the top of the support base can be closed while being abutted at the center. In addition, a pair of freely openable shutter plates is provided, and the upper opening edge of a receiving bag such as a decorative article having cushioning performance and adjustable volume is mounted below the opening on the bottom side. The shutter plate driving device and a vibration detector are provided, and the shutter plate is opened by detecting the vibration caused by the earthquake and operating the driving device. A mounting table that protects ornaments and the like from earthquakes and the like has been proposed (see, for example, Patent Document 3).

JP-A-9-51827 JP-A-9-299203 Japanese Patent No. 3458089

  In the instrument mounting table with anti-vibration protection function of the cited document 1, the shutter is opened by detecting an earthquake, and the instrument dropped from the opened support means is received by the bottom of the box body provided with the shock absorbing material, Is protected from further drops by covering with a protective lid controlled by a release means. On the other hand, in the actual equipment mounting table, even if an impact cushioning material such as a sponge, which is generally considered, is provided in the fall area, if ceramics fall by gravity from a predetermined height position to the bottom, It is estimated that the possibility of destruction is extremely high. Therefore, in Cited Document 1, the effect is to protect from the impact of an object from the outside at the time of an earthquake, and the impact due to gravity drop inside the equipment mounting table related to an article that is extremely vulnerable to impact such as ceramics.

However, the protection means consists of an inner bellows and an outer bellows, and once formed, it is practically difficult to change its size, and the protection means is also connected to the high-pressure tank via an operating mechanism by a tube. It is also difficult to move. Accordingly, there is a problem that it takes a lot of work to protect the display when it is changed. In addition, the display case described in Cited Document 2 has a flexible protective means consisting of an inner bellows and an outer bellows, and is often fitted with glass in a metal frame to ensure observation and viewing. It is practically difficult to protect exhibits from the impact of objects from outside the case. Further, no consideration is given to protecting an exhibit made up of a plurality of objects separated in the vertical direction, such as a lidded vessel, from an earthquake.

  The mounting table that protects ornaments and the like described in the cited document 3 has a flexible bag and can easily and reliably change the volume. A means for preventing damage to equipment due to gravity drop in The configuration in which the upper end opening edge of the receiving bag such as a decorative article having a cushioning performance and adjustable volume is mounted and suspended effectively uses the shock absorption based on the flexibility of the receiving bag. Any shape can be received along the shape with only a small impact, except for a shape protruding in a square shape. In addition, the volume can be easily adjusted by tightening the middle part with a string, etc., and the placed ceramics and other items are sometimes replaced, and even if the shape and size are changed, it matches the items The ability to adjust the volume of the receiving bag is effective for minimizing the impact caused by dropping and for preventing the container from rotating due to dropping. However, no consideration is given to protecting an exhibit made up of a plurality of objects separated in the vertical direction, such as a lidded vessel, from an earthquake.

(Support member)
As shown in FIG. 8, the support member 200 according to the first embodiment includes an upper part 202 and a lower part 204 in which the exhibit A is divided in the vertical direction. The upper part 202 of the exhibit A is supported by a shape-retaining elastic body extending upward from the bottom part 206 of the lower side part 204, for example, a foamed polystyrene holding member 200, and the upper part 202 and the lower side part 204 in the vertical direction. It is placed on the shutter plates 6 and 7 with a gap in between.
When the exhibit A falls and is received by the receiving bag 12, the holding member 200 is received by the bottom portion 206 of the lower side portion 204. At this time, since the bottom portion 206 of the lower side portion 204 is directly received by the receiving bag 12 first, the downward impact force generated by the upper portion 202 is substantially received by the receiving bag 12 by the receiving bag 12. The possibility that the lower portion 204 is destroyed by the downward impact force generated by the upper portion 202 is extremely low.

As shown in FIG. 9, the support member 300 according to the second embodiment includes an upper part 302 and a lower part 304 in which the exhibit A is divided in the vertical direction, and the upper part 302 of the exhibit A is connected to the lower part. 304 has a shape-retaining elastic body, for example, a styrofoam holding member 300, which extends upward from 304 and holds the upper portion 302 in a state of being spaced between the upper portion 302 and the lower portion 304 in the vertical and horizontal directions. .
When the exhibit A falls and is received by the receiving bag 12, the holding member 300 is received by the bottom portion 306 of the lower side portion 304. At this time, since the upper portion 302 is supported by the holding member 300 held by the lower portion 304 without a gap, even if the exhibit A is slightly inclined and is received by the receiving bag 12, the upper portion 302 is generated. The downward impact force thus generated is transmitted substantially evenly to the portion of the lower portion 304 engaged with the holding member 300, and the possibility that the exhibit A is destroyed by the impact force is reduced.
On the other hand, if the holding member is formed of a flexible elastic body as in a conventional package or the like, if the exhibit A is slightly inclined and is received by the receiving bag 12, the downward direction generated by the upper portion 302 is generated. It is considered that the impact force is concentrated in a small area of the engaging portion of the lower portion 304 with the upper portion 302, for example, the mouth portion of the exhibit A, and the lower portion 304 is easily broken.

(Exhibiting mat)
The display cloth a is a sheet-like material having flexibility and having a thickness of about 0.5 to 2.0 mm, such as felt, furano, and synthetic fiber nonwoven fabric. The outer shape and dimensions of the display covering a are determined in consideration of aesthetic balance with the table 40 and the like, and are square in this embodiment. An opening display frame 400 made up of perforations, colored lines, etc. is formed at the center of the exhibition covering a. The opening display frame 400 is matched with the shape and size of the opening 5.

(Operation)
As shown in FIGS. 5 and 6, the display method using the display apparatus having the above-described configuration is first performed by selecting and tightening the strap 15 so that the receiving bag 12 fits the size of the display item A. The receiving bag 12 is made a predetermined size. Next, the shutter plates 6 and 7 are leveled to the closed state. Next, the display cloth a is laid on the table 40 so that the opening 5 and the opening display frame 400 are aligned. Next, the exhibit A is displayed at the center of the opening display frame 400 of the display covering a.

  When the exhibition apparatus detects an earthquake stronger than the set seismic intensity, the vibration detector 22 of the drive device 20 turns on the limit switch with the inclination of the pendulum 22a, and the rotary solenoid 27 and the main relay 31 for operation are turned on. When operated, the shutter plates 6 and 7 are opened. Since the shutter plate 6 is supported by the stopper 10 of the shutter plate 7 when the shutter plates 6 and 7 are opened, the shutter plates 6 and 7 rotate downward at the same speed substantially at the same time. The exhibit A arranged at the center falls into the receiving bag 12 while maintaining the vertical state on display.

  When the exhibit A falls, the display covering a falls together with the display A, that is, the display covering a falls in a state of wrapping the display A so that the surface of the display A is frictional with the receiving bag 12. Will not be damaged by.
