Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an exhibition case used for displaying various exhibits for viewing.

[Prior Art] For example, as an exhibition case used in a museum, art gallery, etc., there is a base having a display floor on the upper surface, and a display case on the base so as to surround an exhibition space formed on the floor. A device is known that includes a case body that is installed in the case body.

In this type of display case, the displayed items in the display space arranged on the base can be viewed from the outside of the case body. Therefore, there are many cases in which most of the case body is made of a glass plate to improve visibility.

In such a display, one of the glass plates can be opened and closed so that the displayed items can be arranged on the floor or replaced.

[Problems to be solved by the invention] However, with such a structure, it is not possible to rigidly connect all the glass plates surrounding the exhibition space, so it is difficult to ensure the rigidity of the entire exhibition case and the airtightness of the exhibition space. difficult to do. In addition, when the glass plate to be opened is large, great effort and care are required to open and close it, especially when the glass plate is opened against gravity.
There is also the danger that the supports that hold the glass panels in the open position may come loose during display or replacement work, causing a catastrophe.

The present invention aims to solve these problems.

[Means for Solving the Problems] In order to achieve the above objects, the present invention employs the following configuration.

That is, the exhibition case according to the present invention includes a base having an exhibition floor on its upper surface, and at least one of the bases, which is movably installed on the base so as to surround an exhibition space formed above the exhibition floor. A case body that can be viewed from inside, and an elevating mechanism that moves the case body up and down between a lowered position on a base that surrounds an exhibition space and a raised position that opens the exhibition space. Features.

[Function] According to this configuration, if the case body in the lowered position is raised by the action of the elevating mechanism and the exhibition space is opened to the front, back, left, and right, exhibits can be placed on the base or exchanged. You can When the case body is lowered onto the base by the action of the elevating mechanism, the exhibit placed on the base will be displayed in the exhibition space surrounded by the case body. With such a case, all the constituent elements such as the glass plate constituting the case body can be rigidly connected or integrated.

[Example] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

The exhibition case 1 of this embodiment is intended to be installed in, for example, an art museum or a museum, and as shown in FIGS. 1 and 2, a base 2 is installed on the floor surface F of these buildings. It is designed to display exhibits on it.

The base 2 is formed into a horizontally long rectangular parallelepiped, and a rubber gasket 3 is provided in a circumferential manner on the peripheral edge 2a of the upper surface, and an exhibition floor 4 for displaying exhibits is installed inside the rubber gasket 3.

A case body 5 is installed on the base 2 so as to be movable up and down so as to surround the exhibition space A formed above the exhibition floor 4. The case body 5 is constructed so that it can be viewed from at least a part of it, but in this embodiment, a glass plate 7 forming a ceiling is held at the upper end of a glass plate 6 forming a peripheral wall, so that the inside of the exhibition space A can be viewed from three sides. It is so that you can see it.

Each glass plate 6 is horizontally long, and its lower end is held airtight in a vertical position inside the holding frame 8, and the joining edges on both sides are rigidly and airtightly connected to each other by adhesive or the like. The glass plates 7 are hermetically sealed and held on the upper ends of these glass plates 6.

Thus, the case body 5 formed in this manner has a lowered position where the exhibition floor 4 of the base 2 faces the lower end opening 8a of the holding frame 8 for normal use, and is in the lowered position. The lower end surface 8b of the holding frame 8 is brought into pressure contact with a rubber gasket 3 provided in a circumferential manner on the upper surface of the base 2.

The case body 5 is raised and lowered from the lowered position to a predetermined raised position as shown in FIG. 3 by means of a lifting mechanism 9 provided within the base 2. The elevating mechanism 9 includes, for example, a guide tube 9b provided at the upper end of a casing 9a containing an electric motor and a speed reducer, and an elevating rod 9C that is movably held in the guide tube 9b. It passes through the top wall of 2 and is connected to the holding frame 8 of the case body 5. Then, the forward and reverse rotation output of the electric motor is decelerated by the speed reducer and converted into a linear reciprocating output, and the linear reciprocating output is used to control the lifting rod 9c.
It is designed to move up and down. As the speed reducer, it is desirable to use a structure that includes a mechanism that can exhibit a self-locking function when the motor is stopped, such as a feed screw mechanism with a small lead or a worm speed reduction mechanism.

With such a configuration, when the electric motor of the elevating mechanism 9 is operated in one direction to cause the elevating rods 9c to project upward all at once, the entire case body 5 supported by the elevating rods 9c rises. It turns out.

When the case body 5 is raised to a predetermined raised position and the lifting mechanism 9 is stopped, the exhibition space A on the base 2 is opened. Therefore, it is possible to quickly display or replace exhibits.

On the other hand, when the electric motor is reversed and the lifting rod 9C is retracted, the case body 5 is lowered.

When the case body 5 is lowered to the above-mentioned lowered position, the lower end surface 8b of the holding frame 8 presses against the rubber gasket 3 on the base 2, thereby sealing the exhibition space A.

Therefore, with such a configuration, there is no need to make the glass plates 6.7 of the case body 5 openable and closable. Therefore, it is possible to simplify the configuration by eliminating a complicated butterfly holding mechanism for holding the glass plate with butterflies, and
The rigidity of the case body can be increased by rigidly contacting the glass plates 6 and 7 with each other. Also, with something like this, there is no need to open a large glass plate against gravity. This saves labor and eliminates the risk of the glass pane being opened and falling from its support. Since the case body 5 does not have an opening/closing part, it is easy to make the case body 5 highly airtight. Therefore, just by providing the rubber gasket 3 or the like between the case body 5 and the base 2 as in this embodiment, it is possible to almost completely seal the exhibition space A.

In the above embodiments, the exhibition case was formed to be horizontally long and the inside of the exhibition space could be seen from the ceiling, but the case body may be made vertically long and lighting equipment etc. may be provided on the ceiling. .

Furthermore, the case body is not limited to a hexahedral shape, and can be modified in various ways, such as a cylindrical shape. Furthermore, the case body is not limited to a structure that completely seals the exhibition space; for example, it may adopt an airtight structure as described above and only allow a small amount of air to enter and exit in and out of the required areas. Supply and exhaust ports may also be provided.

Further, the elevating mechanism for elevating and lowering the case body is not limited to the electric type as shown in the above embodiment, but may be a manual type. If a self-locking mechanism is used as the elevating mechanism as in the above embodiment, a special locking mechanism for locking the case body in the raised position is not required, and persons other than specific persons cannot use the elevating mechanism. A locking mechanism for preventing theft can also be omitted as long as the mechanism is devised so that it cannot be activated.

[Effects of the Invention] Since the present invention has the above-described configuration, the work of displaying or exchanging exhibits can be performed by raising and lowering the entire case body by the function of the lifting mechanism.

Therefore, the exhibition space can be left wide open and the work can be carried out safely and easily. Furthermore, all the components such as the glass plates that make up the case body can be rigidly connected or integrated, making it possible to increase the rigidity of the entire display case and easily create an airtight structure. This provides the effect that the case body can have a relatively free shape.
