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 aligned flush 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 arranged 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 a] By the way, in museums, art galleries, etc., there are cases where exhibits are placed on the exhibition floor in display cases for viewing, and cases where exhibits such as paintings and photographs are hung on the walls. In some cases, the display may be hung for display, and 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 back wall surface cannot be used for displaying paintings and the like.

In addition, not all of the display cases a arranged in the exhibition hall are always used, and depending on the event, it is common for unnecessary items or items that are not suitable for the stand to be displayed. However, since it is not possible to remove them from the exhibition hall each time, conventionally they are often left as they are on the viewing floor f.

For this reason, the inside of the display case a that is not in use is exposed to the front, which tends to cause problems that impair the harmony and elegance of the entire display case.

Conventionally, in museums and the like where it is necessary to change the display mode, a movable partition wall b can be installed near the front of the exhibition case a, as shown in FIG. 28. In other words, when hiding display case a,
A movable partition wall b is provided in front of the display case a, and when paintings C and the like are to be exhibited in an open manner, the paintings C and the like are placed in front of the movable partition wall b. On the other hand, exhibition case a
When displaying an exhibit by placing it on the floor d inside the room, move the movable partition wall b along the rail e to the storage location) so that the exhibition case a is exposed on the viewing floor f. There is.

However, in such a case, a movable partition wall b is required in addition to the display case a, and this movable partition wall b
A rail e for suspending must be buried in the ceiling g of the structure. In addition to the lighting fixtures h and i 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 b is also 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 the movable partition wall b, a defensive fence k is placed 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 makes it possible to move all the glass doors placed on the front of the case body to the door storage section for compact storage, and to easily hide the inside of the display case depending on the situation. The purpose of the present invention is to provide a display case that solves all of the problems described above and can meet a more diverse range of needs.

[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 for storing a glass door at one end of the case body, and a door storage section for storing a decorative door at the other end of the case body. The case body is provided with upper and lower fixing rails that respectively hold the upper and lower edges of the glass door or decorative door that are arranged flush on the front surface of the case body, and upper and lower fixing rails are provided in both door storage sections. The present invention is characterized in that it is provided with a plurality of pairs of upper and lower movable rails parallel to the fixed rail, and a rail drive mechanism for synchronously moving these upper and lower movable rails in parallel.

Further, instead of arranging the door storage sections at both ends of the case body, a structure may be adopted in which the door storage sections are arranged adjacent to one end of the case main body.

In particular, if you want to use two types of decorative doors in addition to the glass door, two door storage sections should be connected and arranged at one end of the case body, and the number of doors should be equal to the number of doors placed on the front of the case body. The number of sets of lower movable rails is one zone, and each adjacent door storage section has two storage zones at the front and back, and one of the four storage zones has a glass door, and the other has two storage zones. 2-] It is better to store different types of decorative doors. Furthermore, in this structure, in order to simplify the operating procedure, it is convenient to be able to transfer the door between both door storage sections in units of zones.

In order to reliably synchronize and parallel move multiple sets of upper and lower movable rails with a simple configuration, the rail drive mechanism is an upper movable rail 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 lower 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's shameful to do that.

When the lower movable rail receives the load from the glass door, 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.

[Function] Door storage sections are arranged at both ends of the case body, and the number of sets of upper and lower movable rails in each door storage section is set appropriately, and each set of upper and lower movable rails is sequentially moved upward by a rail drive mechanism. ,
If it is provided so that it can be moved to a position adjacent to one end or the other end of the lower fixed rail, the door can be transferred between the upper and lower fixed rails and the upper and lower movable rails of each door storage section. It becomes possible.

That is, first, when all the glass doors and decorative doors are held between the upper and lower movable rails of one door storage section or the other door storage section, respectively, each door storage section has a glass door or a decorative door. The decorative doors are arranged in parallel at predetermined intervals in the thickness direction, and are compactly stored. There is no glass door or decorative door on the front of the case body, and the front of the back wall of the display case can be used as a wall for open exhibition.

From this state, for example, the upper and lower movable rails of the first set of the door storage section in which the glass door is stored are placed adjacent to one end of the upper and lower fixed rails, and the upper and lower movable rails are held between the upper and lower movable rails. By pressing the first glass door to one side, the glass door can be moved between the upper and lower fixed rails of the case body. Next, all the upper and lower movable rails in the door storage section are moved in parallel with the other glass doors, and 2
When the upper and lower movable rails of the set are adjacent to one ends of the upper and lower fixed rails, the second glass door can be moved from between the upper and lower movable rails to between the upper and lower fixed rails. Similarly, all the glass doors held between the upper and lower movable rails can be moved between the upper and lower fixed rails of the case body.

As a result, the front of the case body will be closed with a glass door, and a normal display format will be taken.

Also, if you perform the same operation as above on the door storage section where the decorative door is stored when the front side is open,
The front of the case body will be closed with a decorative door, so that the inside of the display case will be hidden.

Furthermore, when you want to remove the glass doors or decorative doors that have been placed on the front of the case body, by performing the above operations in reverse, all the glass doors and decorative doors can be compactly stored in their respective door storage compartments again. It turns out.

On the other hand, when two door storage sections are arranged adjacent to each other at one end of the case body, for the door storage section arranged on the case main body side, the door held by the upper and lower movable rails is placed in the same way as above. Depending on the procedure, it is possible to move the door between the upper and lower fixed rails, and for the door storage section located on the opposite side of the case body, the door held between the upper and lower movable rails can be moved once on the case body side. By moving it between the upper and lower movable rails, it becomes possible to move it between the upper and lower fixed rails.

Moreover, if the procedure is reversed, the glass door and the decorative door will be compactly stored in each door storage section.

Moreover, in such a connected structure, if each door storage section is provided with two storage zones at the front and back, one of the four storage zones thus formed is equipped with a glass door, and the other two are Even if you store the vanity door in the
By using the two empty zones, their storage positions can be changed as appropriate, so that it is possible to selectively take out items from the front of the case body and store them in any door. At this time, in order to be able to transfer the door between the two door storage areas in zone units, it is possible to make the corresponding upper and lower movable rails adjacent to each other, or to arrange a relay rail, etc. Since you can replace each type all at once,
It becomes possible to relatively easily take out the door stored in the back of the storage zone without going through complicated procedures, and the operating procedure is simplified.

, will be stored in. This makes it possible to easily open the front surface of the case body IA, as shown in FIG. 20. Also, from this state, the decorative doors m1 to m. If you want to use it, prepare one set of upper and lower auxiliary movable rails as empty rails in front of zone z1, and
By passing the empty rail, the decorative doors m1 to ml. of zone z3 are opened as shown in FIG. can be sequentially moved to the case main body IA.

On the other hand, if you want to use the decorative doors n1 to nlO from the state shown in Figure 20, first press the door storage part IE as shown in Figure 22.
The decorative doors m1 to m,0 in the front zone z3 of are sequentially transferred to the front zone z1 of the adjacent door storage section 1D, and then,
As shown in FIG. 23, an empty rail (not shown) is prepared in front of the zone z1, and by passing the empty rail, the decorative doors n1 to nlO of the zone 24 are connected to the case body 1.
You can move it to A.

However, the exhibition case has two types of decorative doors m1 like this.
~mH), n1~nlO can be used, and it is possible to appropriately select and use one that matches the atmosphere of the exhibition hall, resulting in higher utility value.

At this time, the door is transferred between the double door storage section ID11E.
As shown in FIGS. 24 to 27, if the corresponding upper and lower movable rails are made adjacent to each other or an intermediate rail is provided so that the operations can be performed simultaneously in units of zones 21 to 24, the 20th The decorative doors n1 to nlO can be easily taken out from the state shown in the figure. One procedure is to first move the makeup LItfn+ to n+o from zone z4 to 22 as shown in FIG. 24, and then move the makeup doors m1 to mlQ from zone z3 to 24 as shown in FIG. Furthermore, the glass doors p1 to p1o are divided into zones as shown in FIG.
Move from z1 to 23. And finally, the vanity door n1
~ n10 is moved from zone z2 to 21. In this way, each of the decorative doors n1 to nlo can be sequentially taken out into the case main body 1A easily with four operations.

[Effects of the Invention] Since the display case of the present invention has the above configuration,
All the doors can be easily removed from the front of the case body, and paintings, etc. can be displayed in the open using the front of the back wall. 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.

Moreover, when the glass door is retracted and an oven exhibition is carried out, the front edge of the exhibition case plays the role of a conventional protective shelf, making it possible to use a large viewing floor at all times. Furthermore, when the display case is not in use, the interior can be easily hidden by placing a decorative door, so the harmony and elegance of the exhibition hall will not be compromised. Furthermore, since two types of decorative doors can be prepared, it is also possible to selectively use the one that best matches the atmosphere of the exhibition hall. Therefore, it is possible to support a variety of display formats with the minimum amount of equipment, and it is possible to quickly perform switching operations.

Further, according to the present invention, by moving the required number of glass doors between the upper and lower 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 change the equipment of the exhibit without being obstructed by the glass.

If the rail drive mechanism is configured as shown in the illustrated embodiment, multiple sets of upper and lower movable rails can be reliably synchronously moved parallel to each other with a simple configuration, and the switching of display modes can be simplified. This operation can be carried out quickly.

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 loads from being applied to 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,
It is possible to prevent the upper chain from lifting up and the opening edge of the glass door from coming off the upper movable rail. Therefore, safety can be effectively improved.

In addition, if rollers are provided at both ends of the upper movable rail and these rollers are brought into rolling contact with the L-oriented support surface provided on the fixed member, the upper movable rail can be accurately positioned in the vertical direction by loosening the upper chain. be able to.
