Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display case for displaying and displaying various exhibits such as works of art and precious metals.
In particular, it relates to an anti-theft display case that can store and store exhibits.

[0002]

2. Description of the Related Art A conventional general display case is constructed in consideration of how to easily display and display an exhibit, and no consideration is given to the anti-theft property. For this reason, at night when the exhibition is not required, the exhibits are transferred from the display case to a storage cabinet having the anti-theft property for storage, or the room itself in which the exhibition case is arranged has the anti-theft structure.

[0003]

Therefore, in the past, when an exhibit is transferred from the display case to the anti-theft storage cabinet, one day at the start and the end of the exhibition is required.
Since it is necessary to transfer the exhibits once, it is extremely troublesome and time-consuming, and there is the inconvenience that extra labor costs are required to perform this work. If the room to be placed has a structure with anti-theft property, there is a disadvantage that a large amount of cost is required.

As a means for solving these inconveniences, there is already a fireproof display case disclosed in Japanese Patent Publication No. 6-87819. This fireproof display case is surrounded by a fireproof protection layer, and a movable rotation axis of the fireproof protection layer is pivotally attached to this fireproof protection layer to close the upper part of the fireproof protection layer in an obscured manner. A movable fireproof protection layer is provided, and when exhibiting, the movable fireproof defense layer is moved to the position where the display case is exposed and opened, and when the exhibition is completed, the display case is lowered and the movable fireproof defense layer is moved. The display case is closed to cover the display case. However, since this fireproof display case is constructed so that the display case is opened and covered by the movement of the pair of rotatable movable fireproof protection layers, there is a disadvantage that the entire structure becomes large and the structure becomes complicated.

An object of the present invention is to solve the above-mentioned inconveniences and provide an anti-theft display case capable of displaying and exhibiting exhibits.

[0006]

In order to achieve this object, a display case according to the present invention has a case-like base body having an open upper surface and a transparent body mounted on the base body so as to cover the open upper surface.

A mounting table driving mechanism for raising and lowering the mounting table and a drive switch for driving the mounting table driving mechanism and the shutter driving mechanism are provided.

In addition to the above-mentioned structure, a control section for driving and controlling the shutter drive mechanism and the mounting table drive mechanism when the drive switch is turned on is provided, and when the drive switch is turned on when the shutter is closed, the control section is operated. And a drive switch is turned on when the shutter is opened, while the shutter closing the upper surface of the opening of the base body is opened by the drive control signal of 1. and the mounting table is elevated from the storage position to the display position. It is also possible to lower the mounting table from the display position to the storage position and to close the opening upper surface of the base body by the shutter in response to a drive control signal from.

In each of the above-mentioned configurations, it is preferable that the base and the shutter have fire resistance. Further, regardless of whether or not the base body and the shutter have fire resistance, it is preferable to provide a lock mechanism that maintains the closed state when the shutter completely closes the opening upper surface of the base body.

Further, an abnormality detection sensor for detecting an abnormal situation such as an earthquake, a fire, or a case body damage, regardless of whether or not the base body and the shutter are fireproof, and the shutter drive upon receiving an abnormality detection signal from the abnormality detection sensor. A control unit for driving and controlling the mechanism and the mounting table drive mechanism is provided, and when the shutter is in the open state and the mounting table is in the display position, the abnormality detection sensor outputs a detection signal, The shutter drive mechanism and the mounting table driving mechanism may be driven by a drive control signal to lower the mounting table to the storage position and the upper surface of the opening of the base may be closed by the shutter.

[0010]

[Operation] At the time of exhibition, the shutter can be opened and the placing table on which the exhibit is placed can be raised to the exhibit position to see the item through the case body. The table is lowered to the storage position, the upper surface of the opening of the base is closed by the shutter, the locking mechanism of the opening / closing part is locked, and the exhibit is stored in the closed space formed by the base and the shutter.

When the substrate and the shutter have fire resistance, they have fire resistance in addition to the anti-theft property. Also,
If a shutter is provided with a lock mechanism that maintains the closed state of the upper surface of the opening of the base body, the anti-theft property is further improved. Furthermore, when the shutter is open and the mounting table is in the exhibition position, the abnormality detection sensor detects an abnormal situation such as an earthquake, fire, or damage to the case body and issues a detection signal. If the mounting table is lowered to the storage position by a signal and the upper surface of the opening of the base is closed by a shutter, even if an attendant or a store clerk is not near the exhibition case, a quick response can be taken when an abnormal situation occurs. You can protect the exhibits.
