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 arranged 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 can solve the above-mentioned problems by moving all the glass doors arranged on the front of the case body to the door storage section and making it possible to store the case compactly. Moreover, it is an object of the present invention to provide an exhibition case that can utilize space more effectively and further promote diversification of exhibition modes compared to a case in which a door storage section is attached to a single case body. The purpose is

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

That is, the display case according to the present invention has a door storage section disposed between the first and second case bodies,
Each case body is provided with upper and lower fixing rails that hold the upper and lower edges of the multiple glass doors arranged flush on the front surface, and upper and lower fixing rails are provided in the door storage section. A plurality of pairs of upper and upper movable rails that can be selectively adjacent to each other at one end, and these upper and upper movable rails are moved synchronously in parallel to sequentially move each set of upper and upper movable rails to the upper and lower fixed rails. The invention is characterized in that it is provided with a rail drive mechanism for adjoining the rail.

When using a glass door, in order to neatly close the front of the door storage area without any effort, install a blind panel between the top movable rail and the top behind the top movable rail to hold the glass door. It is better to keep it.

To prevent gaps from forming between the glass doors, between the glass door and the blindfold panel, and between the blindfold panel and the side wall of the door storage section, install the blindfold panel at the top, a panel held on the upper movable rail. a main body, and a movable member provided retractably on one side edge of the panel body, and the movable member is moved at a position where the upper movable rail is adjacent to the upper and lower fixed rails. It is preferable that the blind panel is made to protrude laterally so that it can be pressed against both the glass door disposed on the first case body and the glass door disposed on the second case body. good.

In order to reliably synchronously move multiple sets of upper and upper movable rails in parallel using a simple configuration, the rail drive mechanism is equipped with an upper part that is stretched between the front and rear upper sprockets and holds the upper movable rails at a predetermined pitch. A lower chain that is stretched between the front and rear lower sprockets and holds the upper movable rail at a predetermined pitch, and a transmission element that connects the sprocket of the upper chain and the sprocket of the lower chain so that they can rotate synchronously. It is preferable that the rotational operating force of the operating handle be transmitted to one of the sprockets.

Preferred embodiments of the transmission element include a chain stretched between upper and lower sprockets, and a transmission shaft.

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 shape. 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.

In order to prevent the upper movable rail from becoming difficult to position in the vertical direction due to loosening of the upper chain, rollers are provided at both ends of the upper movable rail, and these rollers are rolled into contact with the upward supporting surface provided on the fixed member. It is better to leave it there.

[Function] With this kind of configuration, all the glass doors can be held between the pairs of upper and upper movable rails by appropriately setting the number of pairs of upper and upper movable rails. becomes possible. In this state, these glass doors are arranged in parallel at predetermined intervals in the thickness direction and are compactly stored. In this state, there are no glass doors on the front of both case bodies, and the front of the back wall of the display case can be used as a wall for open display.

From this state, for example, place the first rough upper movable rail adjacent to one end of the upper and lower fixed rails, and press the first glass door held by the upper movable rail to one side. For example, the glass door can be moved between the upper and lower fixed rails of the first case body. Next, all the upper and upper movable rails are moved in parallel with the other glass doors, and 2
When the upper movable rail on the set is placed adjacent to one end of the upper and lower fixed rails, the second glass door can be moved from between the upper and upper movable rails to between the upper and lower fixed rails. Similarly, half of the glass doors between the upper and upper movable rails can be moved between the upper and lower fixed rails of the first case body. In addition, by continuing the same operation and sequentially pressing the remaining glass doors held between the top and upper movable rails to the other side, these glass doors are fixed to the top and bottom of the second case body. Can be moved between rails. In this way, the glass doors will be placed flush on the front of both case bodies, allowing for conventional exhibitions.

In addition, if a blind panel is provided, if the upper and upper movable rails are moved further forward and the blind panel is placed adjacent to the glass door, the front of the door storage section will be blocked by this blind panel. Therefore, it is possible to close the front side of the door storage section without complicated operations.

To fully open the display case, simply perform the above operation in reverse.

When the movable member of the blindfold panel is pressed against the inner surface of the side wall of the door storage section, or when the movable member provided on the inner surface of the sidewall of the door storage section is pressed against the blindfold panel, the pressing force is applied to the inner surface of the side wall of the door storage section. The hidden panel comes into close contact with the glass door, making it possible to eliminate gaps between the glass doors, between the glass door and the blind panel, and between the blind panel and the side wall of the door storage section. Moreover, if the pressure is structured so that the force is maintained even after the operation, and the pressure cannot be released without using a special operating handle or key, it is possible to open the glass door in that state. It becomes impossible to do so.

The operation of this rail drive mechanism 7 will be explained as follows. First, when the operating handle 92 is rotated in the normal direction, the rotational operating force is transmitted to the rotating shaft 85 via the shaft 95, and the lower sprocket 82 rotates together with the rotating shaft 85.

As a result, the chain 83 stretched between the lower sprockets 81 and 82 runs, for example, in the direction of arrow X, and the upper movable rails 61 to 66 held on the L side of the chain 83
Eyes move parallel to the front. As this forward movement continues, each upper movable rail 6, to 61□ sequentially moves to the lower fixed rail 4.
The upper movable rails 6, - 610, which have passed through the adjacent position, turn around the lower sprocket 81 on the front side and reversely advance backward (only the upper movable rail 611 moves beyond the adjacent position). ). When the rotating shaft 84 of the lower sprocket 82 rotates in this manner, the rotation is also transmitted to the rotating shaft 75 of the L sprocket 72 via the transmission shaft 91. As a result, the upper chain 73 stretched between the upper sprockets 71 and 72 moves as shown by the arrow Y.
The upper movable rails 51 to 5.1, which run in the direction and are held on the lower side of the chain 73, are connected to the upper movable rails 6, to 61,
Move forward in parallel in synchronization with. If such forward motion is continued, each of the upper movable rails 51 to 511 will be adjacent to the upper fixed rail 3 in sequence, and the upper movable rails 5□ to 5□ have passed through the adjacent position. goes around the front upper sprocket 71 and reverses backward (the upper movable rail 5
1 does not move beyond the adjacent position corresponding to the upper movable rail 611). When the operating handle 92 is reversed, the chains 73.83 operate in the opposite direction, and the upper and lower movable rails 51 and 61 to 5.1 and 6.1 of each set facing upward and downward move rearward. This will result in synchronous parallel movement.

With such a configuration, as shown in FIG. 10, all the glass doors 21 to 2. . The upper and upper movable rails 5 and 6 form a pair. ~5u+ and 61+), these glasses have 121~2+
o and the blind panel 2X are arranged in parallel at predetermined intervals in the thickness direction and are compactly stored. In this state, the case body IA, the glass door 2 on the front of the IC, ~
21n does not exist, and those case bodies IA
, the front surface of the back wall 12 of the IC can be used as a wall surface for open exhibition.

From this state, for example, when closing the front side of the first case main body IA first, the first set of upper movable rails 50.
6 adjacent to one end of the upper and lower fixed rails 3.4, and press the first glass door 2□ held by the upper and upper movable rails 51.6 to the left in the figure. The glass door 2 can be moved between the upper and lower fixed rails 3.4 of the case body IA. Next, all upper and upper movable rails 5
, and 61 to 511 and 611 are moved in parallel together with the glass door 2° to 2+o and the blindfold panel 2X, and the upper movable rail 52.6□ is attached to one end of the upper and lower fixed rails 3.4. When placed adjacently, the two-panel glass door 22 can be moved from between the upper and upper movable rails 52.62 to between the upper and lower fixed rails 3.4, as shown in FIG. Similarly, the upper and upper movable rails 53 and 63 to 55 and 6
6-room glass door 23-2. can be moved between the upper and lower fixed glass doors 3.4 of the first case main body IA.

Also, by continuing the same operation, the upper and upper movable rails 56 and 6
6-5□. and 6□. By sequentially pressing the remaining glass doors 26 to 21o held in between to the right in the figure,
Those glass doors 26 to 210 are attached to the second case body I.
It can be moved between the upper and lower fixed rails 3 and 4 of C. In this way, as shown in FIGS. 1 and 2, the glass doors 21 to 210 are arranged flush on the front surface of the case bodies IA and 1C with the door storage section IB in between. The exhibition will be able to take on the traditional exhibition format.

Then, from this state, the upper and upper movable rails 511.
61 to a position adjacent to one end of each of the upper and lower fixed rails 3.4, and at this position, insert the shaft of the operating knob (not shown) into the front of the blind panel 2X and move the movable member 23.
When x is laterally projected, a glass door 29.2, adjacent to said blind panel 2x, as shown in FIG. will be pushed outward. Therefore, this pressing forces the blindfold panel 2x onto the glass door 25.
．． 2. It can be attached closely to the glass door 2, ~ 25
and between each of the glass doors 26 to 21o, as well as the blind panel 2X and both glass doors 25.2.

It becomes possible to simultaneously close each gap between the blind panel 2x and the side wall 18 of the door storage part IB. Moreover, if the key is pulled out in this state, the movable member 23x is locked in that position, so it is impossible for anyone other than the person who holds the operating handle that serves as the key to open the glass doors 21 to 2+o. This makes it convenient and desirable in terms of maintenance and management.

To open the case body IA and IC again, the above operations can be performed in reverse. First, the glass doors 26 to 210 of the second case main body IC are stored in the door storage section IB, and then the glass doors 21 to 210 of the first case main body IA are stored. Of course, it is also possible to store the items, and depending on the situation, it is also possible to store the items alternately.

Note that the configuration of the rail drive mechanism is not limited to that of the illustrated embodiment; for example, a chain or the like may be used as the transmission element. In addition, if a blind panel is not used, a fixed panel may be attached to the front of the door storage section, or
It is preferable to provide a shutter.

Furthermore, the number of glass doors is of course not limited to that of the illustrated embodiment, and the present invention can be applied to display cases having a large number of glass doors by simply increasing the depth of the door storage section.

[Effects of the Invention] Since the present invention has the following configuration, all the glass doors can be easily removed from the front of each case body, and the front of the back wall can be used to display paintings, etc. It will be possible to display it openly. 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. However...
Therefore, it is possible to support a variety of display formats with the minimum amount of equipment, and the switching work can be performed 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 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.

Furthermore, since the door storage section is disposed between both case bodies and is shared, space can be used more effectively than when a door storage section is provided for each case body. In this case, the door storage section forms a division between the exhibition areas, so not only does the door storage section not get in the way,
On the contrary, it is often convenient, and it becomes possible to display in various ways, such as displaying only one case body open.

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 and the 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.
