Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an exhibition case for displaying exhibits for viewing in museums, art galleries, etc.

[Prior Art] Generally, in this type of display case for displaying valuables, it is important to completely isolate and lock the display space inside the case from the outside in order to prevent theft and tampering. .

On the other hand, when exhibiting items such as arts and crafts, it is necessary to create an appropriate humidity-controlled atmosphere in the exhibition space for preservation purposes. In addition, exhibits are generally easily damaged by heat, so when lighting fixtures are installed in an exhibition space, it is necessary to provide ventilation to prevent the heat generated by the lighting fixtures from becoming trapped.

For this reason, even in existing display cases,
It is customary to open a vent somewhere in the case body to communicate the internal exhibition space with the outside, while keeping it as inconspicuous as possible.

[Problem that the invention aims to solve] However, in order to make the existence of the vent hole difficult to notice and improve the appearance of the case, it is considered that it should be placed on the back side of the case body, which is usually the blind spot for viewers. It will be done.

However, simply opening the vents on the back side causes a problem that restricts the free arrangement of the display case. In other words, the layout of the exhibition case is as follows:
This is because they are often placed against the walls of exhibition rooms, but in such cases the ventilation holes are blocked and they become useless.

The present invention provides a display case that solves these problems.

[Means for solving the problem] In the display case of the present invention, a recess is formed in the upper part of the back of the case body, and a recess is formed from the back.
A distinctive feature of this recess is that it has a vent opening that communicates the exhibition space with the outside.

[Function] In this way, even if the display case is placed closely against a wall, a gap is created between the recess and the wall by the width of the recess from the back of the case body, and the ventilation of the ventilation hole can be ensured. At this time, a vent opens at the top of the back of the case body, allowing the hot air inside the exhibition room to be smoothly exhausted. In addition, if the display case is a top-opening type in which the rear edge of the top lid is hinged to the upper end of the back of the case body, the recess accommodates the dimension that the rear edge protrudes rearward when the top lid is opened; Does not interfere with opening and closing of the top lid.

[Example] Hereinafter, embodiments of the present invention will be illustrated and described.

<Example 1> (Figures 1 and 2) This display case is a top-opening type in which the entire top cover can be opened and closed, as shown in Figure 2, which shows the appearance of the top cover in its closed state (display state). It is made up of
The exhibition case consists of a case body 1 and a top lid 2.
The upper cover 2 is hinged to the rear edge of the upper surface of the case body 1 with a hinge 3 so as to be openable and closable.

The case body 1 has a rectangular upper frame 5 and a lower frame 6 fixed to pillars 4 erected at four corners, side plates 7 at both side openings, and a front panel 8 and a rear panel at the front and rear openings. 9, respectively, and assembled into a hollow box body. The front panel 8 forms the front side of the case body 1, and the rear panel 9 forms the back side. An exhibition floor 11 is provided on the inner periphery of an inner frame 10 provided around the upper frame 5 so that it can be raised and lowered. This exhibition floor 11 has a decorative panel affixed to its upper surface and is lowered flush with the inner frame 10 to airtightly partition an upper exhibition space 12 and a lower base space 13. Note that a decorative panel is attached to the surface of a back plate 14 that defines the rear part of the exhibition space 12 and forms the background of the exhibit X. The base space 13 below the exhibition floor 11 can be accessed by opening the front panel 8 whose lower edge is hinged as an opening/closing door.
The front side can be opened.

On the other hand, the upper lid 2 is made up of a lid frame 15 assembled into a rectangular hollow frame, and a transparent glass plate 16 attached with an edge placed on the inner peripheral edge of the lid frame 15. The lid frame 15 is composed of a rear side portion 15a, side portions 15b, 15b, and a front side portion 15c, and both side portions 15b have side-bent shapes corresponding to the top plate and front plate of the side plate 7. is formed. Thus, when the top lid 2 is closed, the inner surface of the lid frame 15 comes into close contact with the corresponding portion of the case body 1 via a sealing material (not shown),
The exhibition space 12 is hermetically closed.

In addition, an exhibition space 12 is airtightly sealed with a top lid 2.
A front light 17 and a rear light 18 are installed to illuminate the exhibit X from both sides. The front light 17 is attached to the inner frame 10.
The rear light 18 is suspended horizontally with both ends held by support columns 19 erected above.
It is hung horizontally with both ends held by holders 20 attached to the inner surface.

However, this exhibition case has an exhibition space of 12
Ventilation ports 21 and 22 are opened for ventilation. The vent 21 is opened at the front side of the exhibition floor 11 and communicates the exhibition space 12 with the base space 13 below, and introduces cold air into the exhibition space 12 from the empty base space 13 below, as shown by the arrow. It serves as an air supply port.

On the other hand, the ventilation hole 22 is opened in a notch-shaped recess 23 formed in the upper back surface of the case body 1. This recess 23 is formed as follows.
That is, the hollow frame 24 is supported horizontally on the upper end of the back support column 4 on which the rear panel 9 is attached,
The upper lid 2 is hinged onto this via the hinge 3. The back surface 24a of this hollow frame 24
and the rear end surface 2a of the upper lid 2 are flush with each other when the upper lid is closed, and are recessed from the back surface (rear panel surface) of the case body 1 by a step dimension a. Then, a ventilation hole 22 is opened on the back surface 24a of the hollow frame 24 facing this recess 23, and the exhibition space 1
A vent hole 25 is also opened on the upper surface 24b of the hollow frame 24 facing the frame 2. Therefore, exhibition space 12
communicates with the outside from the rear recess 23 through vents 22 and 25 that are open on two sides of the hollow frame 24, and as shown by the arrows in the figure, these serve as exhaust ports to draw hot air from the exhibition space 12 to the outside. accomplish

With the exhibition case configured in this way, cold air is introduced into the exhibition space 12 of the case body 1 through the ventilation holes 21 on the exhibition floor 11, and is exhausted to the outside through the ventilation holes 22 and 25 that open at the upper part of the back. Natural convection takes place. Therefore, hot air from the lamps 17 and 18 and other gases generated from the exhibit X, for example, are not trapped in the exhibition space 12, and a good ventilation effect can be obtained. In this exhibition case, even if the rear panel 9 forming the back surface of the case body 1 is placed close to or in contact with a wall surface,
Since the gap passage is formed by at least the width dimension a of the back surface recess 23, the above-mentioned ventilation effect is not hindered. Furthermore, when adopting such a layout, when the top cover 2 is opened as shown by the imaginary line in FIG. There is no need to worry about it hitting a wall or the like and not being able to open or close.

<Example 2> (Figs. 3 and 4) As shown in Fig. 4, the appearance of this display case in the displayed state includes a large part of the top cover 2 (top part, front part and both side parts)
is surrounded by a glass plate 16 that is rigidly connected to the case body 1, and is fixed to the case body 1 in such a way that it cannot be opened or closed. Necessary exhibits can be taken in and out of the exhibition floor 11 by lowering the exhibition floor 11, which can be raised and lowered by a lifting mechanism 26, into the base space 13 and opening the front panel 8.

Therefore, the ventilation hole 21 opened to the exhibition floor 11
Humidity control box 2 containing humidifier 27 below
8 are installed in series, and the humidified cool air is sent to exhibition space 1 from here.
I am trying to install it in 2.

On the other hand, a vent hole 22 is opened in the upper part of the back surface of the case body 1 in the following manner. In this one,
A part of the upper lid 2 that surrounds the upper rear part of the exhibition space 12,
The maintenance door 2A is a separate maintenance door with a rear light 18 mounted on the inner surface, and parallel frames 29 and 30 are provided at the upper end of the case body 1 for this purpose. The maintenance door 2A is hinged to the rear frame 30 so that it can be opened and closed. Thus, the back surface of the frame 30 located at the upper back surface of the case body 1 is recessed from the surface of the lower rear panel 9 by a width dimension b, and a back surface recess 31 is formed there.
A punching plate 32 with a ventilation hole 22 is provided on the inner surface of the frame 30 and a frame 26 located below, and the exhibition space 12 is communicated with the outside from the back recess 31 through the ventilation hole 22.

Note that the vent 22 is fixed at the front and lower part with the cover 3.
3 and communicates with the illumination space on the back side of the rear light 18 that surrounds a part of the exhibition space.

Now, if configured as above, <Example 1>
For the same reason as mentioned above, even if the display case is placed close to a wall, ventilation can be carried out without any problem through the vent 22 opened in the recess 31 at the upper part of the back surface. In the case of this embodiment, humidified cold air is introduced into the exhibition space 12 from the vent 21 through the humidity control box 28, making it possible to create an appropriate humidity control atmosphere in the exhibition space 12. In this case, the front light 17 is located on the exhibition floor 11.
The reflective plate 3 is placed under the floor of the exhibition space 12.
4 and a heat-cut glass 35, the hot air from the front light 17 is emitted into the base space 13 below.
It is now being exhausted.

Note that the other symbols in FIGS. 3 and 4 correspond to those in FIGS. 1 and 2.

[Effects of the invention] As described above, in the exhibition case of the invention, a recess is formed in the upper part of the back of the case body, and a vent is opened from this to communicate the exhibition space with the outside.
Even if the display case is placed next to a wall, its ventilation will not be hindered, and in the case of a top-opening type, it is possible to eliminate the problem of the rear edge of the top cover hitting the wall and making it impossible to open and close it.
