Description

{SHOWCASES HAVING VIBRATION ISOLATION}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a showcase for exhibition, and more particularly to a showcase for exhibiting a seismic function capable of absorbing a seismic wave transmitted when an earthquake occurs.

In general, a showcase for exhibition purposes is widely used to exhibit cultural assets or artifacts (hereinafter referred to as "exhibits") in a museum or exhibition hall, while simultaneously satisfying both the function of a book and the function of an exhibition.

Such display showcases include 'Korean Utility Model Registration No. 20-0434691', 'Korean Registered Patent No. 10-0755024', and 'Korean Registered Patent No. 10-1782412' filed by the present applicant.

On the other hand, recently, Korea has also been confirmed that it is not an earthquake-safe area, and a showcase for exhibition functions that can safely protect exhibits is being developed. For example, It is actually installed.

Korean Patent No. 10-1749152 refers to a precedent document similar to a display case having the above-mentioned seismic isolation function, and Korean Patent No. 10-1749152 discloses that a seismic isolation device is installed in a lower portion of a main body of a switchgear Disclosure of the Invention The present invention relates to a switchboard having a seismic isolation function for preventing vibration of an earthquake from being transmitted to a main body of a switchgear.

However, the seismic isolation device disclosed in the aforementioned Korean Patent Registration No. 10-1749152, or a conventional seismic isolation device, for example, Korean Utility Model No. 20-2011-0004679, Korean Patent No. 10-0971365 No. 10-1426701 " and the like have the following problems.

First, in the conventional isolation devices, since the unit isolation members constituting the seismic isolation device are fixedly mounted at a predetermined distance apart from each other by the frame, for example, when the area of the seismic display case is large, a plurality of seismic isolation devices may be mounted, There has been a problem in that the seismic isolation device must be newly manufactured.

Secondly, since the conventional seismic isolation devices are fixedly mounted on the frame so as to be horizontally aligned with respect to the frame, there is another problem that when the bottom surface on which the display showcases are installed is not horizontal, a horizontal maintenance work must be performed on the bottom surface separately.

The present invention is configured such that the four unit seismic members are formed as a pair, the distance between the unit seismic members can be expanded and contracted, and the height between the respective unit seismic members and the lower part of the showcase can be individually adjusted To provide a showcase for exhibitions having an isolation function.

The technical objects to be achieved by the present invention are not limited to the above-mentioned technical problems.

According to an aspect of the present invention, there is provided an exhibition display unit having a seismic isolation function, the exhibition display unit comprising: an isolation means including four unitesceive members having an isolation function; Second, third and fourth unit connecting members corresponding to the unit isolating members, and the first, second, third and fourth unit connecting members corresponding to the unit isolating member, The unit isolation members are fixed to the lower portion of the lower chamber of the display case through the first, second, third, and fourth unit connection members, Exhibit display stands can be supported on the indoor floor of a museum or exhibition hall.

Specifically, the first, second, third, and fourth unit connecting members are provided with a lower housing having an upper surface opened, an inner portion provided in an empty vertical housing shape, and a lower surface fixed to the upper plate of the corresponding unit seam member; An upper housing having an open bottom and an inner hollow structure, the upper housing having an upper surface fixed to a lower portion of the lower machine room so as to be able to move up and down in a lower housing; And a height adjustment bag which is disposed between the pair of lower housings and the upper housing, the lower portion of which is adhered to the inside of the bottom surface of the lower housing and the upper portion is adhered to the inside of the upper surface of the upper housing, A pneumatic line may be connected to the height adjustment bag extending from the lower housing to the inside of the lower housing.

More specifically, one or more urethane foam injection holes may be formed on the side surfaces of the lower housings to fix the upper housing, which is adjusted to be lifted or lowered.

More specifically, on the outer side surfaces of the lower housings, lifting and lowering projections are formed to extend along the vertical length direction of the lower housing, and on the inner side of the upper housings, lifting grooves slidably fitted on the lifting protrusions, As shown in FIG.

Specifically, the connecting means comprises: first, second, third and fourth fixing bases which are hollow inside along the longitudinal direction; And first, second, third, and fourth telescoping shafts slidably inserted into the hollow interior of the first, second, third, and fourth fixed members, wherein the first fixed member and the first telescoping member And the second retention base and the second retractable portion are mounted to be orthogonal to the side surfaces of the upper housing of the second unit connecting member, and the third retention base and the third retractable portion are attached to the upper housing of the first unit connecting member at right angles to the side, And the fourth and fourth telescopic parts are mounted at right angles to the side surfaces of the upper housing of the fourth unit connecting member, the second telescopic part is fitted to the first telescopic part, The third telescoping pole is fitted to the second telescoping pole, the fourth telescoping pole is fitted to the third telescoping pole, and the first telescoping pole can be fitted to the fourth telescoping pole.

More specifically, each upper housing and each of the first, second, third and fourth fasteners and the first, second, third and fourth extensible shafts can be connected via a universal joint.

As described above, according to the present invention, since the display showcase having the seismic isolation function is supported on the floor of the museum and the exhibition hall by the four unit seismic members, it is possible to absorb seismic waves transmitted when an earthquake occurs, There is an advantage that the exhibition display shelf 10 can be safely protected.

In addition, since the display showcase having the seismic isolation function according to the present invention has the connecting means for individually adjusting the height of the unit seam members while expanding the distance between the unit seam members, The present invention is advantageous in that it is possible to support the exhibition showcase only by the seismic means of the present invention,
