2. Description of the Related Art Conventionally, in the case of a display case having a flat table-shaped display stand, a display case in which an upper cover body can be opened and closed in a flip-up manner is disclosed in, for example, Japanese Utility Model Publication No. 5-407.
No. 69 has been proposed.

[0003] However, in the above display case, since three sides (left, right and rear sides) of the display surface are surrounded by upright walls, only the upper surface and the front surface of the display item placed on the display surface are transparent glass plates. There is a drawback that the upper lid body having a substantially Γ shape in cross-section can be viewed only from the front side or the upper side.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks of the display case, the present invention is not limited to a flat plate-shaped display surface in which the front and upper surfaces are, of course, transparent, and the rear and right and left side surfaces are all transparent glass plates. SUMMARY OF THE INVENTION It is an object of the present invention to provide a display case having a flip-up type upper cover body which is formed of a transparent plate so that the display can be viewed from any direction.

[0005]

Means for Solving the Problems An object of the present invention, which has been made to solve the above problems, is to provide a display case base having a flat base display surface by using a transparent body surrounding the display surface. An upper lid body having a peripheral side wall and a top wall made of a transparent body disposed on the peripheral side wall is provided between the lower left and right side wall lower portions of the upper lid body and the side surface of the base corresponding to the portion. Attached via a mounting shaft parallel to the front surface of the base and below the exhibition surface, a lever body of an appropriate length that rotates integrally with the shaft is attached to the mounting shaft, and the lever body is mounted on the mounting shaft. When the upper lid is closed, the lever is provided with a resilient member such as a cylinder or a spring for urging the lever in a direction in which the lid is opened when the upper lid is closed. The upper lid is flipped up to the display surface of the base. It is characterized in that mounted for closing.

[0006] In the display case of the present invention, a lever body of an appropriate length that rotates integrally with the shaft is attached to the mounting shaft to position the lever body inside the base.
Since the lever body is provided with a resilient member such as a cylinder or a spring for urging a force in the direction of opening the lid, for example, even if the upper lid has a considerable weight because it is entirely covered with glass, the lid is opened. It is easy, and the load due to the weight of the upper lid can be reduced near the end of closing the lid. Here, the repelling member is formed by a gas spring, and by appropriately selecting the connection position of the lever body coupled to the tip of the gas spring, the acting force applied to the upper lid of the gas spring can be adjusted.

The moment due to the weight in front (left side in FIG. 3) is supported by the gas spring 10 via the lever member 9 while being reduced.

In other words, the gas spring 10
Of the upper lid member 6 acts on the shaft 8 via the lever member 9 in a direction in which the upper lid member 6 is opened, so that even the upper lid body 6 having a considerable weight can be easily lifted up. It becomes possible to open the cover, and when the cover is closed, the upper cover 6 is operated to be closed while the weight of the upper cover 6 is supported by the gas spring 10, so that the user can feel the weight of the cover 6 so much. And can be closed. The connection position of the tip of the gas spring 10 to the lever member 9 is as follows.
One of a plurality of steps (a plurality of positions) is selected in the length direction of the lever member 9 so that the moment generated in the lever member 9 by the repulsive force of the gas spring 10 can be changed.

In the display case of the present invention described above, the weight 1a for stabilization is disposed at the bottom inside the base 1, and the light source device 1b for internal illumination of the display surface 2 and the air conditioning equipment 1c Is provided. The light of the light source device 1b is formed to be transmitted to a light irradiation stand 1d standing on the exhibition surface 2a via an optical fiber cable (not shown). An air outlet 2c for conditioned air is formed in a slit-shaped gap between the board member 2a and the edge member 2b of the exhibition surface 2.

On the other hand, in the above-mentioned display case, the closed upper lid 6 is not opened without permission.
A lock mechanism 11 is provided, and a support mechanism 12 that guides the opening and closing operation of the upper lid 6 and that holds the position of the upper lid 6 when the lid is opened is provided. This will be described below. .
