Description

TECHNICAL FIELD The present invention relates to an exhibition case used for displaying various exhibition items for viewing.

[Prior Art] For example, as a display case used in a museum or an art gallery, a base having a display floor on its upper surface and an exhibition space formed on the floor are surrounded by the base. It is known to have a case body installed in the. In this type of display case, the display items in the display space arranged on the base can be viewed from the outside of the case body. For this reason, there are many cases where the majority of the case body is made of a glass plate to improve the visibility.

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

[Problems to be Solved by the Invention] However, with such a structure, it is not possible to rigidly contact all the glass plates surrounding the exhibition space, so the rigidity of the entire exhibition case and the tightness of the exhibition space are secured. Difficult to do. Also, if the glass plate to be opened is large, it requires a great deal of effort and attention to open and close, especially if the glass plate is opened by gravitational force. There is also a risk that the support for holding the glass plate in the open position during the replacement work may come off and cause a catastrophe.

The present invention aims to solve such problems.

[Means for Solving Problems] The present invention adopts the following configurations in order to achieve the above objects.

That is, the display case according to the present invention includes a base having an exhibition floor on an upper surface and a display space formed above the display floor so as to surround the display space so that the display case can be moved up and down so as to have four surrounding surfaces. And a case body that can be seen from the upper side, and a lifting mechanism that raises and lowers the case body from the lowered position on the base that surrounds the exhibition space by supporting it from the lower side to the raised position that opens the exhibition space. And. Then, the case main body is provided with a holding frame having a brim portion standing upright on the peripheral edge, a glass plate forming a peripheral wall standing on the holding frame by locking the lower edge inside the brim portion, and these glass plates. And a glass plate forming a ceiling attached to the upper end of the holding frame, and the elevating mechanism is pierced through the ceiling wall of the base so as to project and retract, and the lower end of the holding frame is supported by the upper end. It is characterized in that it is equipped with an elevating rod that moves.

[Operation] According to such a configuration, if the case body in the lowered position is lifted by the function of the elevating mechanism to open the exhibition space in the front, rear, left and right, the exhibits can be placed on the base or exchanged. You can Then, when the case main body is lowered to the base by the function of the elevating mechanism, the exhibit placed on the base is displayed in the exhibition space surrounded by the case main body. However, with such a structure, all of the constituent elements such as the glass plate constituting the case body are rigidly joined or connected, although the case is a so-called five-sided case in which the inside can be visually recognized from the four sides and the upper side. Can be integrated. Moreover, in the present invention, since the case main body is raised and lowered by being supported only from the lower surface side, the components for raising and lowering the case main body can be easily recognized from the four surrounding surfaces and the top surface. There is no adverse effect.

Particularly, in the present invention, since the glass plates forming the peripheral wall are erected on the holding frame having the flange portion on the peripheral edge, it is possible to obtain sufficient shape retention strength only by joining the cut edges of these glass plates. Therefore, it is not necessary to join the glass plates together via an opaque metal pillar member or the like. That is, if the glass plate forming the peripheral wall is placed on the holding frame while being locked inside the flange part, it is possible to prevent the improper shift movement of the lower end part of the glass plate, and to cut the glass plates from each other. It becomes easy to secure the overall strength only by joining them with an appropriate adhesive element. Therefore, the visibility of the viewer in the exhibition space can be dramatically improved as compared with the case where the glass plates are joined to each other through the opaque pillars or crosspieces.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

The display case 1 of this embodiment is for installation in, for example, a museum or a museum. As shown in FIGS. 1 and 2, the base 2 is installed on the floor surface F of these buildings. It is configured to display exhibits on it.

The base 2 is formed in a horizontally long rectangular parallelepiped, and a rubber packing 3 is provided in a circular shape on a peripheral portion 2a of an upper surface of the base 2, and an exhibition floor 4 for displaying exhibits is installed inside the rubber packing 3. A case body 5 is installed on the base 2 so as to be vertically movable so as to surround the exhibition space A formed above the exhibition floor 4. The case body 5 is a glass plate 6 forming a peripheral wall.
A glass plate 7 forming a ceiling is held at the upper end of the display space A so that the inside of the exhibition space A can be seen from five sides. That is, the case main body 5 is configured such that the interior of the exhibition space A can be visually recognized from each of the four surfaces and the upper surface.

Each glass plate 6 is horizontally long, and the lower end of each glass plate 6 is held inside the holding frame 8 in a vertical posture in an airtight manner, and the joint edges on both sides are airtightly joined by an adhesive or the like. Then, the glass plate 7 is provided on the upper end of these glass plates 6.
Is hermetically sealed and held. That is, the four glass plates 6 forming the peripheral wall are erected on the holding frame 8 with the lower end portions thereof being locked inside the collar portion 8c formed in a standing posture on the peripheral edge of the holding frame 8. The left and right cuts of each glass plate 6 are directly joined by an adhesive or the like.

Thus, in the case main body 5 formed in this way, the position where the display floor 4 of the base 2 faces the lower end opening 8a of the holding frame 8 is a descending position used for normal use, and in this descending position The lower surface 8b of the holding frame 8 is in pressure contact with the rubber packing 3 provided in a circular shape on the upper surface of the base 2.

Then, the case body 5 is moved up and down between the lowered position and a predetermined raised position as shown in FIG. 3 by the lifting mechanism 9 provided in the base 2. The elevating mechanism 9 is configured to elevate and lower the case body 5 by being supported only from the lower surface side. For example, a guide cylinder 9b is provided at the upper end of a casing 9a containing an electric motor and a speed reducer.
In addition, the guide cylinder 9b holds the elevating rod 9c so that the elevating rod 9c can be moved up and down, and the upper end of the elevating rod 9c is penetrated through the top wall of the base 2 so that it can be retracted. Is connected to. Then, the forward / reverse rotation output of the electric motor is decelerated by the speed reducer and is converted into a linear reciprocating output, and the linear reciprocating output causes the elevating rod 9c to move up and down. As the speed reducer, it is desirable to use a structure including a mechanism such as a feed screw mechanism with a small lead or a worm speed reduction mechanism that can exhibit a self-locking function when the electric motor is stopped.

With such a structure, when the electric motor of the elevating mechanism 9 is operated in one direction to cause the elevating rods 9c to simultaneously project upward, the entire case body 5 supported by the elevating rods 9c rises. It will be. Then, by raising the case body 5 to a predetermined raised position and stopping the elevating mechanism 9, the exhibition space A on the base 2 is opened. Therefore, the work of newly displaying or exchanging the exhibited item can be quickly performed.

On the other hand, when the raising and lowering rod 9c is immersed in the motor by reversing the electric motor, the case body 5 is lowered. Then, when the case body 5 is lowered to the above-described lowered position, the lower surface 8b of the holding frame 8 presses the rubber packing 3 on the base 2 to seal the exhibition space A.

Therefore, with such a structure, it is not necessary to open and close the glass plates 6 and 7 of the case body 5. Therefore, it is possible to eliminate the complicated butterfly-holding mechanism or the like for holding the glass plate to simplify the configuration, and to rigidly contact the glass plates 6 and 7 with each other to enhance the rigidity of the case body 5. . That is, although this is a five-sided case that can be seen from the four sides and the top,
The strength of the entire case body 5 can be increased by rigidly contacting all the surfaces of the glasses 6 and 7. In addition, if it is such a thing, it is not necessary to open a large glass plate against gravity, so it is possible to save labor, and there is a risk that the opened glass plate will fall when the support is removed. Also disappears.
Further, since the case body 5 has no opening / closing portion, it is easy to make the case body 5 highly airtight. Therefore, as in this embodiment, the case body 5 and the base 2 are
The display case space A can be almost completely sealed only by providing the rubber packing 3 or the like between the display case space A and the display case space A.

Moreover, since the glass plate 6 forming the peripheral wall is erected while restraining the position of the glass plate 6 on the holding frame 8 having the collar portion 8c on the peripheral edge, it is sufficient to join the cut edges of the glass plates 6 to each other. Shape strength can be obtained, and it is not necessary to bond glass plates to each other through an opaque column member. That is, if the glass plate 6 forming the peripheral wall is placed on the holding frame 8 while being locked inside the collar portion 8c, it is possible to reliably prevent the improper movement of the lower end portion of the glass plate 6. The strength of the whole can be easily secured simply by joining the cut edges of the glass plate 6 with an appropriate adhesive. Therefore, compared with the case where the glass plates 6 and 7 are joined to each other through an opaque column or a crosspiece, the visibility of the viewer in the exhibition space can be dramatically improved.

The case body is not limited to a structure that completely seals the exhibition space. For example, after adopting the airtight structure as described above, only a small amount of air flowing into and out of the required place is allowed. You may make it provide a supply and an exhaust port.

Further, the raising / lowering mechanism for raising / lowering the case body is not limited to the electric type as shown in the above-mentioned embodiment, but may be a manual type. If the elevating mechanism having the self-locking function as in the above embodiment is used, a special locking mechanism for locking the case body in the ascending position is unnecessary, and a person other than a specific person can elevate the elevating mechanism. The lock mechanism for theft prevention can be omitted as long as the mechanism is not operated.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, the work of displaying or exchanging exhibits can be performed by raising and lowering the entire case body by the action of the raising and lowering mechanism.
Therefore, it is possible to open the exhibition space greatly and to carry out the work safely and easily.

Moreover, according to such a configuration, although the case body is a five-face type case body capable of looking into the exhibition space from the four sides and the upper surface, the configuration of the glass plate or the like constituting the case body Since all parts can be rigidly joined or integrated, the rigidity of the entire display case can be reasonably and effectively increased, and an airtight structure can be easily obtained. Particularly in the present invention, since the glass plate constituting the peripheral wall is placed on the holding frame in a state where the lower end of the glass plate is locked to the inside of the flange, the glass plate has good shape retention. Therefore, even if the glass plates are not joined to each other through a metal column or the like, a highly rigid and sturdy case body can be configured. Therefore, the visibility of the exhibition space for the viewer can be reasonably improved.

Further, since the elevating mechanism is configured to elevate and lower while supporting the case main body only from the lower surface side, the constituent elements of the elevating mechanism are not only visible from the four surrounding surfaces but also from the upper surface. Does not have any adverse effect. Therefore, the effects described above can be obtained without impairing the function of the five-sided case.
Specifically, since the elevating mechanism includes an elevating rod that penetrates through the top wall of the base so as to project and retract and supports the lower surface of the holding frame at its upper end, the elevating rod is It is possible to prevent the components of the lifting mechanism from being exposed to the outside when the case body is stopped at the lowered position by immersing it in the pedestal, and the case body holding frame is opaque. If you do so, you will not even be able to see it. Therefore, it is possible to provide an excellent exhibition space in which unnecessary things are completely out of the sight of the viewer.
