BACKGROUND OF THE INVENTION
The present invention relates to a guide structure for a side end portion of a liftable front panel in a large display device installed in a museum or an art museum, for example.
[0002]
[Prior art / problems to be solved by the invention]
Exhibit devices in museums and art galleries are generally installed along the walls of buildings. By providing an exhibition stand along the wall, a front panel that extends to the ceiling is fixed above the front of the exhibition stand. The structure defines the height of the opening surface of the exhibition space.
[0003]
However, the height dimensions of the exhibits vary, so if the front panel has a constant height as in the past, it may not be possible to display it effectively, and the anti-theft and disaster prevention features. There is also a problem.
In this regard, it is conceivable that the front panel can be configured to be movable up and down, but since this type of exhibition device has a large width, the front panel is divided into a plurality of pieces, and each front panel is moved up and down individually. You must be able to do it.
[0004]
When a plurality of front panels are arranged in this way, from the point of view of aesthetics, the front surfaces of the front panels are aligned on the same plane, and between the end faces of adjacent panels so that the back of the front panel is not exposed. It is desirable to close the gap.
For this requirement, for example, the joint structure between the panels adopted in the partition is diverted so that the ridges are formed on the end surfaces of one adjacent front panel so as to extend over the entire length, and the end surface of the other front panel For this reason, it is considered that the side edges of the adjacent front panels may be fitted to each other by, for example, forming a groove in which the protrusion fits tightly so as to extend over the entire length.
[0005]
However, when adjusting the height of each front panel, the front panels are not necessarily raised and lowered all at once, but only a part of the front panel can be raised and lowered to use only a part of the exhibition space. The front panel may be raised or lowered one by one or multiple pieces from each other. Therefore, when the side end surfaces of adjacent front panels are closely fitted, when the front panel is lifted, the front panel is moved between the side end surfaces of the front panel and the front panel. There is a possibility that the front panel cannot be raised and lowered smoothly due to the twisting.
[0006]
An object of the present invention is to smoothly lift and lower a plurality of front panels with their front surfaces aligned and with the gaps between the front panels closed.
[0007]
[Means for Solving the Problems]
In order to achieve this object, the exhibition apparatus of the present invention
“In an exhibition apparatus in which a plurality of front panels that define the height of the opening surface of the exhibition space are arranged so as to be movable up and down so as to extend in series in a plan view,
Of the adjacent front panels, a protrusion projecting toward the side end surface of the other front panel is provided on the side end surface of one front panel so as to extend over substantially the entire length. On the side end surface of the panel, a groove that fits the protrusion of the one front panel in a non-contact state is provided to extend over substantially the entire length, and the side end of at least one of the front panels A roller that can roll in a state in which it is fitted in a protrusion or groove on the adjacent front panel so that it cannot be displaced back and forth is provided on the part. ''
It was made the configuration of.
[0008]
[Effects of the invention]
With this configuration, when only a part of the front panel is moved up or down, or when the front panel is moved up or down one by one in order, the lifting is guided by the rollers. It moves up and down smoothly without any occurrence.
Further, since the roller is fitted to the protrusion or groove of the opposite front panel so as not to move back and forth, the two adjacent front panels are held in a state where their front surfaces are aligned. Furthermore, since the protrusions and the front panel are fitted together, the gap between the end faces of the front panel is closed.
[0009]
Therefore, according to this invention, it has the effect that a front panel can be raised / lowered smoothly in the state which improved aesthetics.
In particular, the configuration according to claim 2 has the advantage that the front panel adjacent to each other is guided to each other at two front and back positions, so that backlash in the front and rear direction can be remarkably suppressed and the front panel can be moved up and down more smoothly. . Moreover, since the protrusion of one front panel and the protrusion of the other front panel have the same shape, there is an advantage that the manufacturing cost can be reduced by making the first roller and the second roller common.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
