Description

[Detailed description of the invention]

- [Industrial Application Field] The present invention relates to an exhibition case used to display 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 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]

By the way, in museums, art galleries, etc., there are cases in which exhibits are placed on the exhibition floor in display cases for viewing, and exhibits such as paintings and photographs are hung on the walls. It is desirable to be able to adopt any of the embodiments as appropriate depending on the type. 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 b can be installed near the front of the display case a, as shown in FIG. 15. In other words, when displaying painting C etc. in the open, ``the entire exhibition case a is concealed by a movable partition wall b;
A painting C etc. is placed in front of the movable partition wall b. On the other hand, when exhibits are placed on the floor d in the exhibition case a, the movable partition wall b is moved along the rail e to the storage area, and the exhibition case a is displayed on the viewing floor f. I'm trying to get it out. 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 building. 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. It is an object of the present invention to provide a display case that can solve these problems and is easy to improve its appearance and take anti-theft measures. [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 invention described in claim 1 includes upper and lower fixed rails that respectively hold the upper and lower edges of the plurality of glass doors arranged flush on the front surface of the case body;
A plurality of pairs of upper and lower movable rails that can be selectively adjacent to one end of these upper and lower fixed rails, and these upper and lower movable rails are synchronously moved parallel to each other to separate each set of upper and lower movable rails. This is an exhibition case equipped with a rail drive mechanism for sequentially adjoining the upper and lower fixed rails, and the outer side of the upper and lower movable rails behind the upper and lower movable rails for holding the glass door. A blind panel is provided, which includes a pair of panel bodies whose edges are rotatably and slidably supported, and a hinge that connects the inner edges of these panel bodies, and the two panel bodies are held together. The glass door is characterized in that when the glass door is rotated to a position where the glass door is rotated, the distance between the outer edges of the two panel bodies is set to be larger than the width of the glass door. Further, in the display case according to the invention described in claim 2, the blind panel can be rotated and slid on one side edge on the upper and lower movable rails rearward of the upper and lower movable rails for holding the glass door. A panel body supported by the panel body, a rotating arm rotatably provided at the upper and lower ends of the panel body, and a rotating arm pivotally attached to the rotating end of the panel body and supported so as to be slidable on the upper and lower movable rails. When the panel body is rotated to a position parallel to the upper and lower movable rails, the distance between one side edge of the panel body and the outer edge of the slider is , the width of the glass door is set to be larger than the width of the glass door. 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 force of the photographing 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 having bevel gears on the upper and lower sides. In order to be able to accommodate various ceiling heights without having to select parts or process parts on-site, the transmission shaft should be made by fitting a plurality of square pipes in a telescopic manner. It is preferable to 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, in order to prevent the upper edge of the glass door from coming off the upper movable rail due to the lifting of the -L section chain, a lifting prevention member that can slide on the inner surface of the upper chain is installed between the front and rear upper sprockets. It is effective to provide 4. In order to prevent the vertical positioning of the upper movable rail from becoming difficult due to loosening of the two-part 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 configuration, when all the glass doors are held between the pair of upper and lower 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. From this state; if you place the first set of upper and lower movable rails adjacent to one end of the upper and lower fixed rails and press the first glass door held by the upper and lower movable rails sideways, The glass door can be moved between the upper and lower fixed rails. Next, all the upper and lower movable rails are moved in parallel with the other glass doors, and the second set of upper and lower movable rails are moved to the upper and lower movable rails.
When placed adjacent to one end of the lower fixed rail, 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 between the upper and lower movable rails can be moved between the upper and lower fixed rails. In this way, the glass door will be placed flush with the front of the display case, allowing conventional display. With the blindfold panel held and the upper and lower movable rails adjacent to the upper and lower fixed rails, when both panel bodies are rotated until they are flush, the outer edges of both panel bodies will rotate. At the same time, the blind panels slide away from each other, and the distance between the outer edges of the blind panel becomes larger than the width of the glass door. As a result, when the outer edge of one panel body is pressed against the side wall of the door storage section and the outer edge of the other panel body is pressed against the side edge of the adjacent glass door, the pressing force causes It becomes possible to bring the glass doors into close contact with each other, the glass door and the blind panel, and the blind panel and the side wall of the door storage section. Furthermore, if the blind panel is locked in this state, it will be impossible for anyone other than the person who owns the key to open the glass door. Additionally, when the blind panel is held on the upper and lower movable rails via a rotating arm, etc., and the panel body is rotated to a position parallel to the upper and lower movable rails, the slider will be moved by the rotating arm. The upper and lower movable rails are slid, and the distance between one side edge of the panel body and the outer edge of the slider increases. Therefore, if one side edge of the panel body or the outer edge of the slider is pressed against one side edge of the glass door or the inner surface of the side wall of the door storage section, the pressing force will cause the gap between the glass doors and between the glass door and the blind panel to It becomes possible to eliminate the gap between the window and between the blind panel and the side wall of the door storage section. To fully open the display case, simply perform the above operation in reverse. [Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 12.

When held between the movable rails 5l and 61 to 55 and 65, the glass doors 21 to 2 are arranged parallel to each other at predetermined intervals in the thickness direction, and are compactly stored. In this state, the glass doors 21 to 2 are not present on the front surface of the case body IA, and the front surface of the back wall 12 of the case body IA can be used as a wall surface for open display. From this state, the first set of upper and lower movable rails 51 and 6 are brought adjacent to one end of the upper and lower fixed rails 3 and 4, and the first set of upper and lower movable rails 5, 61 held by the upper and lower fixed rails 5, 61 By pressing the glass door 21 sideways, the glass door 21 can be moved between the upper and lower fixed rails 3 and 4. Then,
All the upper and lower movable rails 51 and 6, ~56 and 66 are moved in parallel with the other glass doors 22 to 2, and the second set of upper and lower movable rails 5■ and 6■ are moved to the upper and lower fixed rails. 3, 4
When placed adjacent to one end, the second glass door 2 is moved from between the upper and lower movable rails 52 and 6 to the upper and lower fixed rails 3 and 4.
can be moved between. Similarly, the glass doors 23 to 25 between the upper and lower movable rails 53, 63 to 5, and 65
can be moved between the upper and lower fixed rails 3 and 4 (see Fig. 9). In this way, as shown in FIGS. 1 and 2, the glass doors 2, to 25 will be placed face-to-face on the front of the case body IA, making it possible to display as before. . Upper and lower movable rails 56, 6 that hold the blind panel 26

4c with an operation handle (not shown) and rotate the center of the blind panel 26 forward as shown by the arrow in FIG. 10, the outer edges 24a,
The 25a side rotates backward and slides away from each other. As shown in FIG. 11, both panel bodies 24,
When the center of the blind panel 26 is further rotated toward you until 25 becomes a negative surface, each panel body 24, 25
The distance m between both side edges 24a and 25a becomes larger,
The outer edge 24a of one panel body 24 is pressed against the inner surface 18g of the side wall 18f of the door storage part IB, and the outer edge 25a of the other panel body 25 is pressed against one side edge 25a of the adjacent glass door 25. Therefore, due to the pressing force, the adjacent glass doors 2, ~25 are pushed one after another toward the side opposite to the door storage section IB, and the adjacent glass doors 2, ~2,
The glass door 25 and the blind panel 26, and the blind panel 26 and the side wall 18f of the door storage section 1B are all in close contact with each other. As a result, there is no gap between them, and the front surface of the door storage part IB is closed so that the inside thereof is not exposed to the outside, so that the overall appearance of the display case is improved. With the outer edges 24a, 25a of both panel bodies 24, 25 pressed against the inner surface 18g of the side wall 18f and the glass door 25, either panel body may be fixed to the lower movable rail 66 etc. with bolts or the like. good. Alternatively, if the blindfold panel 26 is provided with a locking mechanism so that its bolts can be locked, the glass doors 2, - 25 can be locked, and theft can be effectively prevented. To open the case main body IA again, the above operation can be performed in reverse. 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. Furthermore, it goes without saying that the number of glass doors is not limited to that of the illustrated embodiment, and the present invention can also be applied to display cases with a large number of glass doors by simply increasing the depth of the door storage section. . On the other hand, the blind panel 1026 shown in FIGS. 13 and 14
This includes a panel body 124 whose one side edge 124a side is rotatably and slidably supported by upper and lower movable rails 1056 and 1066 rearward of the upper and lower movable rails for holding the glass door; Upper end 124 of panel body 124
The upper stay 126 and the lower stay 127, which are rotating arms rotatably provided at the C and lower ends 124d, respectively, and the upper and lower movable rails 1056 which are pivotally connected to the rotating ends 126a and 127a of the respective stays 126 and 127. , 1066 and are slidably supported by upper and lower sliders 128 and 129. Upper and lower movable rails 1056, 10
66 is a wide groove 1o5b a, 1066 a that slidably holds the upper and lower sliders 128 and 129, and a narrow structure 10 that is continuous with each wide groove 1056a 1106ha.
56b, 106bb, and a narrow groove 105'
6 b, 1066 b, upper and lower stays 126, 127
Pin 1 that connects the upper and lower sliders 128 and 129
24e, and pins 1026 protruding from the upper end 124c and lower end 124d of the one side edge 124a of the panel body 124.
It is designed so that a can slide. Further, the other side edge 124b of the panel body 124 is biased forward by a spring (not shown). According to such a configuration, the upper and lower movable rails 1056
, 1066 adjacent to the upper and lower fixed rails, bias the other side edge 124b of the panel body 124 rearward,
When rotated to a position parallel to the upper and lower movable rails 1056 and 1066, one side edge 124a of the panel body 124
The distance between the upper and lower sliders 128 and the 12 outer edges 130 is larger than the width of the glass door, and the outer edges 130 of the upper and lower sliders 128 and 129 are connected to the side wall 1 of the door storage section.
It is pressed against the inner surface 118g of 18f. Therefore, due to the reaction, one side edge 124 of the panel body 124. a
presses one side edge 102sa of the adjacent glass door 1o2, and pushes the glass doors together, the glass door 1025, and the blindfold panel 102.
6, and the blind panel 1026 and the side wall 118f are all in close contact with each other, so that there is no gap between them, and the appearance can be improved. In this way, the blind panel 1026 can be constructed from one panel main body 124, which reduces the number of manufacturing steps compared to the case where two panel main bodies are screwed together. ,
Since there is no border in the center, the appearance can be made even better. [Effects of the Invention] Since the present invention has the above structure, all the glass doors can be easily removed from the front of the case body.
It becomes possible to display paintings, etc. 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. 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. On the other hand, if all the glass doors in the door storage section are placed on the front of the case body, the front side of the door storage section is closed off with a blind panel, and mechanical devices such as movable rails and rail drive mechanisms inside the door storage section are blocked. Since exposure to the outside can be effectively avoided, the door storage part does not give a sense of discomfort and the appearance is good. Furthermore, by placing the glass door on the front of the case body and locking the blind panel, the glass doors, the glass door and the blind panel, and the blind panel and the side wall of the door storage section are brought into close contact. In addition, since the entire glass door can be locked, the appearance can be particularly good, and theft of exhibits can be effectively prevented. Moreover, since the blind panel of the present invention does not require any telescope panel or the like to be incorporated into the panel body, the structure can be simplified and implementation is easy. A panel in which the entire panel body is pivoted, as in the second aspect of the invention, can particularly reduce the number of manufacturing steps and has a good appearance. 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 install and change exhibits without being obstructed by the glass. If the rail drive mechanism is constructed 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 construction, and the switching of display modes can be 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.
