DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display case installed in an exhibition hall such as an art museum or a museum.

[0002]

2. Description of the Related Art Conventionally, there are various types of display cases used for displaying collections in museums and the like. Among them, there is a cubic base of the display case made of metal aggregate or the like. A frame is formed, and a transparent plate such as a glass plate is mounted on the underframe to exhibit a so-called lantern shape.

A transparent plate, for example, a glass plate is erected on a frame as described above so as to form a square tube, and a top plate is mounted on the plate. For example, since the pillars are formed in a form where the pillars are erected, the pillars often hinder the appreciation of the exhibits, and the appearance is lacking in smartness. However, at least one side of the rectangular glass plate in the display case needs to be in the form of a door that can be opened and closed so that the display items can be put in and out of it. Pillars for attaching the hinges are essential.

[0004] In view of the above points, a display case in which pillars are not provided at the four corners of a display case having a lantern shape, and one surface of a glass surface is freely opened and closed has been proposed as Japanese Patent Publication No. 2-1484. I have. In the proposed display case, the four corners are glass surfaces because there are no pillars at the four corners of the case, but one glass surface of the case has a door structure that can be opened and closed, so the base of the case and the case The ceiling side is made of a metal structure other than a glass plate, and a hinge structure for opening and closing a glass plate on one surface of the display case is incorporated in the upper and lower portions of the metal.

[0005] The display case having the above-mentioned structure achieves the intended purpose of being able to cover all four sides with glass because no pillars are provided at the four corners of the case. However, since the ceiling side of the case is not formed of a glass plate, it has an external appearance. Above, the head of the case felt heavy and lacked in smartness. Also, when the display case is placed, for example, in an exhibition space dug into a pit, and the case is viewed from obliquely above from a corridor or a gallery around the pit, the opaque ceiling portion hinders the line of sight. There was also a problem that the exhibits were hard to watch.

On the other hand, a display case in which four peripheral surfaces and a ceiling surface are formed of a transparent plate such as a glass plate is disclosed in Japanese Patent No. 2709023.
No. has been proposed. Although this display case was able to wipe out the problems of the conventional display case described above, the structure of this part became extremely complicated because the open / close structure of one side of the transparent plate was a structure that used both a rail mechanism and a hinge mechanism. There are many problems in terms of manufacturing labor and maintenance.

[0007]

SUMMARY OF THE INVENTION In view of the above, the present invention is not limited to the case where the display case has a pillar shape at the four corners in the case of a display lamp which is entirely in the shape of a lantern. Of the so-called lantern-shaped display case that has a relatively simple structure with a door function that can be opened and closed by a relatively simple structure, as well as being formed in a form that is completely visible from all directions around it. The task is to provide.

[0008]

Means for Solving the Problems The structure of the display case of the present invention, which has been made to solve the above-mentioned problems, is described in the following. In a display case in which a transparent plate is erected and the respective transparent plates are hermetically bonded to each other, and in a display case in which a transparent top plate is hermetically mounted on an upper end of each of the transparent plates, one outer plate of the base is provided. The side plate and the transparent plate integrated with the base can be freely opened and closed with respect to the base, and at the beginning and end of the opening / closing operation, perform a substantially linearly separating / contacting operation with respect to the opening surface of the base in a small section. By providing the pivot point via a different double hinge, the openable and closable side plate and the transparent plate erected on the upper side thereof come into close contact with and separate from the open end surface of the display case formed by the other side plate and the transparent plate. Formed to be opened and closed while front The closed state of the side plate is held by a base and a lock mechanism provided on the side plate, and an extruding mechanism for extruding the side plate from the inside of the base toward the door opening side when the door is opened is provided. .

In the display case of the present invention having the above-mentioned construction, each of the transparent plates erected on the four sides of the base has left and right ends formed on an inner inclined surface of 45 degrees, so that the transparent plate is formed at 90 degrees by a joining line at both ends of the glass plate. The corners are formed. This point
The same applies to the case where both ends of each of the four side plates on the base are formed on a 45-degree inner inclined surface.

In addition, air holes or slits (not shown) communicating with the inside of the frame 1a are formed on the four circumferences of the floor member 2.

The four side plates 3 to 6 are joined to each other via the transparent adhesive of each of the side plates 3 to 6 by aligning the mutual contact ends at an angle of 45 degrees when viewed from a plane. The joint 1 is formed so that the base 1 is located at the apex of a square when viewed from a plane, and the lower end of a glass plate 7 to 10 as an example of a transparent plate, which will be described later, is placed on the upper end surface side with an adhesive. Grooves 3a to 6a that are hermetically connected and supported are formed.

Numerals 7 to 9 respectively fit the lower ends of the grooves 3a to 5a formed on the upper surfaces of the side plates 3 to 5 fixed to the outer surface of the frame 1a, and make the left and right side end surfaces flat. By joining the surfaces that are in contact with each other at an angle of 45 degrees as seen from the airtight, the joints formed by the joining lines are joined airtightly, and aligned with the joints of the side plates 3 to 5. In this case, the glass plate is a vertically long rectangle as viewed from the front.

10 is integrated with the side plate 6 by being airtightly fitted into the groove 6a of the opening / closing side plate 6 and standing upright.
It is a glass plate that can be opened and closed integrally. This glass plate 10
Also, the left and right ends are chamfered similarly to the 45-degree chamfers on the side end surfaces of the adjacent glass plates 7 and 9. Then, a thin elastic sealing material (not shown) is formed on the end surfaces of the glass plates 7 and 9 formed at 45 degrees corresponding to the glass plate 10.
Is affixed.

Numeral 11 denotes upper surfaces of the glass plates 7 to 9 fixedly mounted on the side plates 3 to 5, which are airtightly joined at right and left side end surfaces formed at 45 degrees to each other. This is a ceiling glass plate mounted and fixed on the glass plates 7, 8, 9 via an adhesive as a transparent airtight sealing material. This sky glass plate
In FIG. 11, an airtight sealing material (not shown) is also provided on the edge of the lower surface where the glass plate 10 to be opened and closed enters.

In the display case described above, the weight 1b for balance, the air-conditioning means 1c in the display case,
Similarly, dimming of a light source for illuminating the inside of the case, a power supply device 1d, and the like are arranged. The side plate 6 to be opened and closed and the glass plate 10 integral with the side plate 6 are supported by an inner surface of the side plate 6 and a hinge mechanism 12 attached to the inside of the base 1 so as to be openable and closable. The equipped side plate 6
An opening surface formed by the end surfaces of the other side plates 3 and 5 of the base 1, and
A locking means 13 is provided for pulling into the opening surfaces formed by the end faces of the glass plates 7 and 9. On the other hand, when the locking mechanism 13 is released when the door is opened, the side plate 6 is moved from the inside of the base 1 to the opening side. Extrusion mechanism 14 with gas damper etc. to slightly push and urge
Is provided.

As shown in FIGS. 2, 3 and 5, the hinge mechanism 12 has shafts 12a and 12b at one end on the inner surface of the opening / closing side plate 6 and at the front end on the inner surface of the fixed side plate 3, respectively. A main hinge member 12c having a substantially U-shaped cross section across the entire height of both side plates 6, 3 and an inner surface of the both side plates 3, 6 are arranged at positions different from the shafts 12a, 12b. And a sub-hinge member 12f, which is attached to the shafts 12d and 12e and has a substantially L-shaped flat cross-section that is slightly larger than the cross-sectional shape of the hinge member 12c. In the hinge mechanism 12 of this example, the main hinge member 12c rotates substantially 180 degrees while mainly supporting the weight of the side plate 6 and the glass plate 10, and the sub hinge member 12f connects the side plate 6 and the glass plate 10 integrated therewith. , Defining a 90-degree rotation and its trajectory as a single door, and both hinge members 12c
The shafts 12a and 12b and the shafts 12d and 12e of the shafts 12f and 12f are displaced, so that the opening and closing side plates 6
Is opened and closed linearly at an angle to the opening surface.
In FIG. 5, reference numeral 12g denotes a cutout opening provided to prevent the hinge member 12c from interfering with the shaft 12e of the auxiliary hinge member 12f.

In the display case of the present invention formed as described above, the glass plate 10 and the opening / closing side plate 6 integral therewith are connected to each other by the hinge mechanism as shown in FIGS. With the 90 degrees open by the action of 12, the exhibit is put in and out. When the side plate 6 is in an open state, an exhibit (not shown) is placed on the floor member 2 serving as a display surface, and the side plate 6 is closed together with a glass plate 10 integral therewith. In operation, the side plate 6 and the glass plate 10 are
A 45-degree cut surface formed on each of the left and right ends is respectively a 45-degree cut surface on the front side of the left and right side plates 3 and 5 on the base 1 and a left and right glass plate 7 and 9 on the front side. It moves almost linearly at the terminal end of the closed door so that the upper end surface of the glass plate 10 is in close contact with the sealing material below the front edge of the top glass plate 11 so that the upper surface of the glass plate 10 is in close contact with the sealing material. Closed. The above-mentioned operation of the closing end of the side plate 6 and the glass plate 10 is performed by pulling the side plate 6 integrally with the glass plate 10 into the inside of the base 1 by the operation of the lock mechanism 13 and holding and fixing the position at this position. The left and right sides of the closed side plate 6 and the glass plate 10 at the left and right sides are 45 degrees, and the opposing side plates 3, 5 and the glass plates 7, 9
And is held in close contact with the end face formed at 45 degrees.

As shown in FIGS. 5 and 6, the lock mechanism 13 holds and locks a hook member 13a having a substantially U-shaped flat surface attached to an upper portion of the inner surface of the opening / closing side plate 6 while rotating. The holding lock 13d is formed by a holding piece 13b that locks and a cam piece 13c that locks the rotation of the rotated holding piece 13b.

The holding member 13b rotates by rotating the hook 13c while the hook member 13a enters the groove 13e, and at the end of rotation of the holding member 13b, the cam 13c reverses the rotation of the holding member 13b. And the hook member 13a is locked and locked. For this reason, in order to release the lock, a release bar T (see FIG. 2) is inserted from the outside to insert the cam piece.
Pressing the release operation piece 13f provided on the head of 13c
By rotating c in the opposite direction to the direction of locking, the holding piece 13b is rotated in the reverse direction, and the hook member 13a is released from the holding piece 13b so as to be unlocked. In the present invention, two sets of left and right lock mechanisms 13 are provided on the upper portion of the inner surface of the side plate 6. Needless to say, the structure of the lock mechanism 13 itself may be a structure other than the above example.

On the other hand, as the push-out mechanism 14 acting when the door is opened, one having the form illustrated in FIGS. 2 and 4 is used as an example. That is, a gas damper is provided on the inner side of the side plate 7 of the base 1.
While providing 14a in a substantially horizontal posture, its tip 14b abuts against the back surface of the main hinge member 12c when the door is closed, and the damper 14a is slightly compressed at the position of the door end of the hinge member 12c when the door is closed. It is positioned and provided. With this arrangement of the gas damper 14a, when the locked locking mechanism 13 is released and the side plate 6 can be opened, the tip 14b of the gas damper 14a compressed by the main hinge member 12c at the time of closing the door is mainly used. Since the hinge member 12c acts in the direction of pushing the hinge member 12c toward the door opening side, this force acts as the door opening urging force of the side plate 6 integrated with the glass plate 10. Thus, the side plate 6 integrated with the glass plate 10 is opened with a relatively light operating force.

Here, when the lighting power supply 1d inside the base 1 is operated and the air conditioner 1c is started up, the display object is placed on the floor 2 and the display object is placed on the floor 2 from any of four sides of the case or from above. It will be possible to appreciate without obstructing the line of sight. The glass plate in the above example can be replaced with a transparent plate made of synthetic resin.

[0023]

The present invention is as described above. An entirely transparent plate made of a glass plate or the like is erected on the upper outer periphery of a flat rectangular metal base, and a ceiling made of an entirely transparent plate is provided on the upper end of the transparent plate. In the display case provided with, a side plate on one surface of the base is provided on the base via a so-called double hinge so as to be openable and closable, and one transparent plate is fixedly supported at a lower portion of the side plate on the openable and closable side. The display case can be viewed from above and around the display surface by forming it openable and closable, so that it is possible to view the display without obstructing the field of view from both above and around. As a matter of course, the following unique effects can be obtained.

In particular, according to the present invention, the opening / closing side plate integrated with a transparent plate such as a heavy glass plate is supported by two hinge members having different axial positions to open and close. Even with a heavy door body and an open / close side plate integrated with a transparent plate such as a glass plate in a biased load state, not only the special effect of being able to stably open and close can be obtained, At the opening / closing start and end, the minute section is operated almost linearly with respect to the display case opening surface, so that the opening end surface of the display case and the end surface of the opened and closed side plate and the glass plate are smoothly brought into close contact with each other, While this state is forcibly secured by the lock mechanism, when the door is opened, the heavy door is smoothly put into the opening operation by the operation of the door push-out mechanism, so that the display case is large and heavy. Even large and heavy It is possible to perform the opening and closing of Akiraban relatively easily and smoothly.
