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] High-grade exhibition cases installed in museums, art galleries, etc. are constructed so that adjacent glass doors can be flush with each other in the closed position.

Conventionally, in this type of display case, for example, a fixed glass fixed to the front surface of the case body and a movable glass door whose upper and lower edges are held by movable rails are arranged adjacent to each other. The movable rail can be turned horizontally, and the fixed rail is disposed in front or behind the upper and lower edges of the fixed glass. When replacing exhibits, etc., the movable rail is rotated until its end is continuous with the fixed rail, and the glass door held on the movable rail is moved onto the fixed rail, so that the front surface of the movable rail is moved to the fixed rail. It is set to be open.

Various other types have been developed, but all of the conventional types have fixed glass as described above, making it impossible to open the entire front of the display case.

[Problem to be solved by the invention] By the way, in museums, art galleries, etc., there are cases where exhibits are placed on the display floor in display cases for viewing, and cases where exhibits such as paintings and photographs are hung on the walls. It is desirable to be able to adopt either mode as appropriate depending on the type of event.

However, when exhibiting paintings, etc., it is undesirable for glass to exist between the viewer and the viewer. Therefore, in conventional display cases where the glass cannot be completely removed from the front, the front of the back wall cannot be used for displaying paintings or the like.

Conventionally, in museums and the like where it is necessary to change the display mode, a movable partition wall has been installed near the front of the exhibition case a, as shown in FIG. That is, when exhibiting paintings C etc. in the open, the entire exhibition case a is hidden by a movable partition wall, and the paintings C etc. are placed in front of the movable partition wall. on the other hand,
When displaying an exhibit by placing it on the floor d in the exhibition case a, move the movable partition wall along the rail e to the storage area and expose the exhibition case a onto the viewing floor f. That's what I do.

However, in such a case, a movable partition wall is required in addition to the display case a, and a rail e for suspending this movable partition wall must be buried in the ceiling g of the building. . Furthermore, in addition to the lighting fixture h11 for illuminating the inside of the display case a, a lighting fixture j for illuminating the paintings C and the like displayed open in front of the movable partition wall is separately required. All of these must be prepared from the architectural design stage, and the equipment will be large-scale and complex. Moreover, when displaying paintings C etc. in the open using a movable partition wall, there is a defensive fence k in front of the wall.
There is also the problem that the actual usable area of the viewing floor f is unduly narrowed.

The present invention aims to solve such problems.

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

In order to be able to accommodate various ceiling heights without selecting parts or machining parts on site, the transmission shaft may be made by fitting a plurality of square pipes in a telescopic manner. It is preferable to

If the load from the glass door is to be carried by the upper movable rail, install a support member between the front and rear lower sprockets that slides against the inner surface of the lower chain to prevent excessive stress from being placed on the lower chain. It is necessary to keep it. In this case, to prevent the upper chain from lifting and the upper edge of the glass door coming off the upper movable rail,
It is effective to provide a floating prevention member that can slide on the inner surface of the upper chain between the front and rear upper sprockets.

To prevent vertical positioning of the upper movable rail from becoming difficult due to loosening of the upper chain, rollers are provided at both ends of the upper movable rail, and these rollers are placed in rolling contact with the upward supporting surface provided on the fixed member. Good.

In order to improve safety when moving the glass door from the fixed rail to the movable rail, it is preferable to provide a stopper for locking the glass door at the end of the movable rail on the side opposite to the fixed rail.

[Function] With this configuration, when all the glass doors form a pair and are held between the upper movable rails, these glass doors are arranged in parallel at a predetermined interval in the thickness direction. and takes a compactly stored form. In this state, there is no glass door on the front of the display case, and the front of the back wall of the display case can be used as a wall for open display.

Therefore, there is no need for any equipment for arranging a movable partition wall in front of the display case. Furthermore, the lighting equipment used to illuminate the exhibits on the exhibition floor can be used as is for open exhibitions, which eliminates the problem of the need for two systems of lighting. therefore,
With the minimum amount of equipment, it is possible to support a variety of display formats, and the switching work can be done quickly.

Moreover, when the glass doors are retracted and an open exhibition is held, the front edge of the exhibition case will function as a conventional defensive fence, making it possible to use a large viewing floor at all times.

Further, according to the present invention, by moving the required number of glass doors between the upper and upper movable rails, it is possible to open any part of the display case as appropriate. Therefore, not only in the case of an open exhibition, but also in the case of a normal exhibition in a case, it is possible to safely and quickly install and change exhibits without being obstructed by the glass.

In addition, if the rail drive mechanism is configured as shown in the illustrated embodiment, it becomes possible to reliably move multiple sets of upper and upper movable rails in synchronized parallel motion with a simple configuration, and the switching of display modes is simplified. It is possible to perform the process quickly with simple operations.

In addition, by using a transmission shaft made of multiple square pipes fitted together in a telescopic manner as a transmission element, it is possible to accommodate various ceiling heights without having to select parts or process parts on site. becomes possible.

Furthermore, by providing a support member that slides and supports the inner surface of the lower chain between the front and rear lower sprockets, it is possible to prevent excessive stress from being placed on the lower chain.
It becomes possible to easily bear the load of the glass door. In addition, if a floating prevention member that can slide on the inner surface of the upper chain is provided between the front and rear upper sprockets,
This can prevent the upper chain from lifting up and the upper edge of the glass door from coming off the upper movable rail. Therefore,
Safety can be effectively increased.

Also, if rollers are provided at both ends of the upper movable rail and these rollers are brought into rolling contact with the upward supporting surface provided on the fixed member,
The loosening of the upper chain allows accurate vertical positioning of the upper movable rail. Therefore, it becomes possible to smoothly move the glass door from between the fixed rails to between the movable rails.

Furthermore, by providing a stopper for locking the glass door at the end of the movable rail on the side opposite to the fixed rail, it is possible to prevent the glass door from moving out of control when moving from the fixed rail to the movable rail, thereby increasing safety. can be improved.
