Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhibition case in which an internal exhibit can be viewed from a ceiling surface and at least three surrounding surfaces.

[0002]

2. Description of the Related Art Conventionally, as this kind of display case, there is known a display case in which a display space is formed on a base, and four surfaces of a peripheral wall surrounding the display space and a ceiling surface are made of glass plates. ing. Thus, in such an exhibition case, for example, the floor of the exhibition space is configured to be able to move up and down, a door is provided on one surface of the base, and the floor is lowered into the base with the door open. By doing so, it is generally possible to display or exchange the exhibit items to be arranged in the exhibit space.

[0003]

However, in order to adopt such a structure, it is indispensable to set the height of the base to be equal to or greater than the height of the display. Therefore, it cannot be applied to an exhibition case having a flat base.

In order to deal with such a situation, it has been considered that one glass plate surrounding the exhibition space can be opened and closed in a sliding door type. The lower edge is guided by parallel rails provided on the base side and the ceiling side, respectively. Therefore, there is a problem that the upper rails provided especially on the ceiling side are likely to be a hindrance when viewing the exhibits.

An object of the present invention is to eliminate such a problem.

[0006]

The present invention takes the following means in order to achieve such an object. That is, in the display case according to the present invention, the display space is formed on the base, and at least three surfaces of the peripheral wall surrounding the display space and the ceiling surface are formed by transparent wall bodies such as glass plates. It is characterized in that one of the transparent walls is supported by a rail mechanism provided only on the base side, and the transparent wall can be opened and closed in a sliding door manner.

As a preferred mode of the rail mechanism, it is provided with a rail which is pivotally supported at one end on a base and is capable of substantially horizontal turning, and a moving block which is guided by the rail and is capable of advancing and retracting in a substantially horizontal direction. The movable block is fixed to a portion near one side of the lower wall of the transparent wall to the moving block, the rail is arranged substantially horizontally, and the rail can be projected and retracted by parallel movement on the base. And a moving block that is guided by the rail and is capable of moving back and forth in a substantially horizontal direction. The moving block is fixed to a part of the transparent wall near the one side of the lower end skirt. Or a rail fixed to the base with the tip positioned slightly outward of the base end, and a moving block that is guided by the rail and can move back and forth in a substantially horizontal direction. In the moving block One side portion near the lower end skirt portion of the Akirakabe body can be given such as that fixed.

[0008]

With this structure, the transparent wall body supported by the rail mechanism can be slid in a sliding door manner. Therefore, it is possible to move items in and out of the exhibition space without raising and lowering the floor of the exhibition space, and it is possible to omit the elevating mechanism and set the height of the base freely. Become. Moreover, since only the lower edge of the transparent wall is supported by the rail mechanism, it is not necessary to provide the rail on the ceiling portion of the exhibition space. Therefore, it is possible to eliminate the problem that the visibility of the exhibition space is impaired by the rails and the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, this display case has a display space 2 formed on a base 1, and has peripheral walls 4, 3, 5, 6 and a ceiling surface 7 surrounding the display space 2. It is composed of glass plates 31, 41, 51, 61, 71 which are transparent walls, and the glass plate 61 located on the back surface 6 is supported by a rail mechanism 8 provided only on the base 1 side so as to be openable and closable. There is.

More specifically, the glass plate 61 on the rear surface 6 has a metal lower end skirt 62 which is fixed to the lower edge of the glass plate 61 and doubles as the back wall of the base. It is supported by the base 1 through the 8.

As shown in FIG. 2, the rail mechanism 8 has a base end 81a pivotally supported by the base 1 so that the rail mechanism 8 can turn substantially horizontally.
1 and a moving block 82 which is guided by the rail 81 and can move back and forth in a substantially horizontal direction, and a portion 62a near one side of the lower end skirt portion 62 of the glass plate 61 is fixed to the moving block 82. ing. That is, as shown in FIGS. 2 and 3, a bracket 83 is fixed to the base end 81 a of the rail 81, and the bracket 83 is attached to the frame 1 of the base 1 via the shaft 84 and the thrust bearing 85.
It is pivotally supported by a fixed plate 13 installed between 1.12. The rail holding means 86 is provided at a portion 81c near the turning end of the rail 81.
It is supported by the fixed plate 13 via. As shown in FIGS. 4 and 5, the rail holding means 86 includes a horizontal advancing / retreating plate 86a protruding from the rail 81 inward of the base 1 and a lower surface of the horizontal advancing / retreating plate 86a on the fixing plate 13 of the base 1. Roller group 86b slidably supported and the horizontal advancing / retreating plate 86
a. The horizontal advancing / retreating plate 86a is rolled on the upper surface of the roller group 8a.
The upper roll 86c is a tire-shaped upper roll 86c that is pressed against the 6b. As shown in FIG.
Also, as shown in FIG. 6, a tongue piece 87 is projected. The tongue piece 87 is formed with a lock hole 87a with which a lock rod 88a of a lock 88 provided on the base 1 is engaged, and slit-like moderation holes 87b and 87c with which a moderation roller 89 is engaged.
The moving block 82 is a block-shaped member having a well-known slide bearing structure, and the circulating ball 8 accommodated therein is provided.
The rail 81 is slidably held via the rail 2a. Then, the moving block 82 is attached to the glass plate 61.
The lower end skirt portion 62 is fixed to one side portion 62a on one side with a bolt (not shown). Reference numeral 63 is a bracket for preventing the lower end skirt portion 62 of the glass plate 61 from lowering on the free end side.

Next, the operation of the display case will be described. 1 and 2 show a state where the glass plate 61 is closed. In this state, the peripheral edge of the glass plate 61 is in close contact with the edges of the other glass plates 41, 51 and 71, and the rail 81 is stopped at the position most pushed inward.
In this position, the lock rod 88a of the lock 88 can be engaged with the lock hole 87a of the tongue piece 87 by applying a locking operation to the lock 88. Glass plate 61
In order to open the lock lever 88, the lock 88 is first unlocked to pull out the lock rod 88a from the lock hole 87a. In this state, since the moderation roller 89 is engaged with the first moderation hole 87b, the rail 81 does not rotate carelessly. Then, when the rotating end 62b of the lower end hakker portion 62 is pulled outward against the temporary holding force of the moderation roller 89, the rail 81 and the lower end hakker portion 62 horizontally swing about the shaft 84 as a fulcrum. The side of the rotating edge 61a of the glass plate 61 separates from the adjacent glass plate 41 (see the phantom line in FIG. 2). At this position, the second moderation hole 87c of the tongue piece 87 and the moderation roller 89 engage with each other, and the rail 81 is temporarily held. Then, when the glass plate 61 is urged to the right in the figure, the moving block 82 is guided by the rail 81 and moves horizontally, and the glass plate 61 slides in a sliding door while maintaining the standing posture. It will be opened. By performing the operation opposite to the above, the glass plate 61 can be returned to the original closed position.

The structure of the rail mechanism is not limited to that described above, and may be, for example, the one shown in FIG. 7 or the one shown in FIGS. 8 and 9.

That is, the rail mechanism 108 shown in FIG.
Is a rail 81 arranged substantially horizontally and the rail 81
A pair of rail holding means 86 for holding the base 1 so as to be capable of projecting and retracting in parallel with the base 1, and a moving block 82 which is guided by the rail 81 and can move back and forth in a substantially horizontal direction. The movable block 82 is formed by fixing a part of the glass plate 61 near one side of the lower skirt portion 62. Each rail holding means 86 is the same as that of the above-mentioned embodiment, and the same or corresponding portions are designated by the same reference numerals and the description thereof will be omitted. Then, this is a glass plate 61
By pulling the lower end skirt portion 62 and the like toward the front, the rail 81 moves outward in parallel, and the glass plate 61 is separated from the other adjacent glass plates 41 and 51. Then, when the glass plate 61 is urged in the lateral direction, the moving block 82 is moved.
Slides along the rail 81 to the right in the figure, and the glass plate 61 is opened to the state of being taken out to the right in the figure.

The rail mechanism 208 shown in FIGS. 8 and 9 is
A rail 81 fixed to the base with the tip positioned slightly outward of the base end, and a moving block 82 that is guided by the rail 81 and can move back and forth in a substantially horizontal direction. A portion 62a near one side of the lower end skirt portion 62 of the glass plate 61 is fixed to the moving block 82. That is,
The rail 81 is inclined in a horizontal plane, and the moving block 82 supported by the rail 81 is fixed to the lower end skirt portion 62 of the glass plate 61 via an inclination member 63. Then, with such a configuration,
When a lateral biasing force is applied to the glass plate 61, the moving block 82 slides rightward in the figure while being gradually displaced outward along the inclined rail 81. Therefore, the glass plate 61 slides open laterally while moving in parallel in the thickness direction (see the imaginary line). Then, when an operation force in the opposite direction is applied to the glass plate 61, the glass plate 61 slides leftward in the drawing while moving inward in parallel, and finally the adjacent glass plates 41,
It comes into close contact with the edge of 51 and closes. Since the rail 81 can be fixed in this embodiment, the structure can be simplified and the reliability can be improved. In this embodiment, as shown in FIG.
First and second auxiliary rails 280 and 281 are fixedly mounted on the base 1, and the lower end skirt portion 6 is attached to the auxiliary rails 280 and 281.
The driven rollers 282 and 283 pivotally supported by the roller 2 are brought into rolling contact with each other, so that the outward tilting of the glass plate 61 can be more reliably prevented. That is, the first auxiliary rail 280 is of a channel shape that opens downward, and the driven roller 282 that is axially attached to a portion near the moving block on the inner surface side of the lower end skirt portion 62 via the bracket 282a.
Are brought into rolling contact with the roller rolling surface 280a formed inside the auxiliary rail 280. The second auxiliary rail 281 is a plate-shaped member, and is a driven roller 28 that is axially attached to the lower end surface of the lower end skirt portion 62 in the vicinity of the moving block.
3 is transferred. Thus, the two auxiliary rails 280 and 281 have the roller rolling surfaces 280a.
281a is fixed so as to be parallel to the rail 81, and always exerts an action of suppressing a large torsional force between the rail 81 and the moving block 82.

Further, the transparent wall body is not limited to the glass plate, and it goes without saying that it may be a synthetic resin or the like.

In addition, within the scope of the present invention,
Various modifications are possible.

[0019]

As described above in detail, according to the present invention, the transparent wall constituting one surface of the peripheral wall can be opened like a sliding door, so that regardless of the shape and size of the base. The exhibition space can be opened, and it is possible to easily display and exchange the exhibits. Moreover, since the transparent wall is supported by the rail mechanism provided only on the base side, there is no need to provide any rails that may obstruct the view in the ceiling. Therefore, it is possible to provide an exhibition case with good visibility of the exhibited item.
