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 the display case of this scale, for example, a fixed glass fixed to the front part 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 systems have been developed, but all of the conventional systems 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 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. 17. That is, when exhibiting painting C etc. in the open, the entire exhibition case or a is hidden by a movable partition wall, and painting C etc. is 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 lighting fixtures h and i for illuminating the inside of display case a, a lighting fixture j for illuminating 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.

Recently, in order to solve this problem, upper and lower fixed rails that hold the upper and lower edges of the multiple glass doors arranged flush on the front of the case body, and upper and lower fixing rails have been developed. It includes a plurality of pairs of upper and lower movable rails that can be selectively adjacent to one end of the fixed rail, and a rail drive mechanism that sequentially brings these upper and lower movable rails adjacent to the upper and lower fixed rails. A display case is being considered. However, by moving the glass door placed on the front of the case body between the upper and lower movable rails, the front of the case body can be freed up. They can be stored compactly by stacking them in the thickness direction.

However, what has been conventionally considered is that a running wheel is provided at the lower edge of the glass door, and this running wheel is held removably by the lower fixed rail or the lower movable rail, thereby reducing the total weight of each glass door. It is designed to support. Therefore, if a glass door is warped due to manufacturing distortion, the warp tends to be amplified by gravity, and this tendency becomes more pronounced as the height of the glass door increases. In addition, because clear visibility is required for the glass doors of exhibition cases, it is common to use glass that has not been subjected to anti-glare treatment such as surface coating, so that light is not scattered on the surface. It will be faithfully reflected. Therefore, if the degree and direction of the warpage of each glass door is uneven, a large disturbance will occur in the reflection of lighting, etc., and this disturbance will give a strong impression to viewers.

Therefore, it may spoil the overall impression of the exhibition floor.

It is an object of the present invention to solve all of these problems and at the same time to realize an exhibition case in which the flatness of the glass door can be effectively improved.

[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 includes a case body,
A case comprising an upper fixed rail, a lower fixed rail, a storage section, a plurality of upper movable rails, a plurality of glass doors, a suspension support mechanism, and a rail drive mechanism. The main body has a front opening in which the glass door is to be arranged flush, and the upper fixed rail is provided on the upper edge of the front opening, and the upper fixed rail is positioned slightly behind the upper fixed rail. The lower fixed rail is provided on the lower edge of the opening, the storage section is provided with the upper movable rails arranged at intervals in the front and back on the ceiling portion, and the glass door is provided with the above suspension support mechanism. is movably suspended and supported on the upper fixed rail or the upper movable rail via a It is characterized in that it is configured to be selectively adjacent to the rail.

In addition, other components include the case body, the upper fixed rail, the door holding mechanism, the storage section, the multiple upper movable rails, the multiple glass doors, the suspension support mechanism, and the rail drive mechanism. The case body has a front opening in which the glass door is arranged flush, and the upper fixing rail is provided at the upper edge of the front opening, and
The door holding mechanism is provided at the lower edge of the front opening, and includes a movable member that presses one side of the glass door in the thickness direction, and a fixed member that supports the other side of the glass door pressed by the movable member. The storage area is located on the ceiling.
The glass door is provided with the upper movable rails arranged at intervals in the front and rear, and the glass door is movably suspended and supported on the upper fixed rail or the upper movable rail via the suspension support mechanism. The rail drive mechanism may be configured to synchronously move the upper movable rails in parallel so that each of the upper movable rails can be selectively adjacent to the upper fixed rail.

In order to avoid making the door holding mechanism large-scale, the fixing member should be
It is preferable to use a lower fixed rail provided at the lower edge of the front opening of the case body, or to use the front edge of a rotatably provided exhibition floor as a movable member.

In order to effectively utilize the space below the exhibition floor for storage, etc., the case body must be placed between a base frame installed on the floor, a column erected at the rear end of this base frame, and a position midway between the columns. It is preferable to include a floor frame extending forward from the support column and a ceiling frame extending forward from the upper end of the support, and a fixed rail is preferably attached to the lower surface of the ceiling frame.

In order to adjust the upper fixed rail horizontally and prevent the glass door from moving accidentally, it is best to tighten the upper fixed rail to the ceiling frame via a height adjustment spacer. .

When a glass door is suspended and supported via a single suspension support mechanism, the center portion of the upper edge of the glass door is suspended and supported. In this case, the suspension support mechanism is comprised of a traveling body that moves along the upper fixed rail or the upper movable rail, a single clamp that clamps the center of the upper edge of the glass door, and this clamp. The traveling body may be provided with a suspension rod that is suspended and supported, or the traveling body that moves along the upper fixed rail or the upper movable rail may be paired with a central portion of the upper edge of the glass door. It is conceivable that the vehicle be equipped with a clamp and a suspension rod for suspending and supporting the clamp on the traveling body.

The glass door can also be suspended and supported via a pair of suspension support mechanisms. In this case, a specific embodiment includes a traveling body that moves each suspension support mechanism along an upper fixed rail or an upper movable rail, a single clamp that clamps the upper edge of the glass door, and a single clamp that clamps the upper edge of the glass door. A clamp that is equipped with a suspension rod that suspends and supports the traveling body, or a pair of clamps that clamps the traveling body that moves along the upper fixed rail or the upper movable rail and the vicinity of the side edge of the glass door. and a suspension rod for suspending and supporting these clamps on the traveling body.

When arranging multiple glass doors flush, in order to ensure that the side edges of adjacent glass doors are in close contact with each other, the suspension support mechanism must be able to allow the glass doors to swing in the width direction. It is good to have one set up.

In order to prevent unreasonable force from acting on the clamping portion of each glass door, it is preferable to provide a suspension support mechanism that allows the glass door to swing in the thickness direction.

When each glass door is suspended and supported by a plurality of suspension support mechanisms, in order to be able to correct the inclination of the glass door, each suspension support mechanism is preferably provided with a height adjustment means.

In order to prevent the glass door from swinging in the thickness direction in the storage section, the storage section is provided with a lower movable rail that holds the lower edge of the glass door suspended and supported by each of the upper movable rails, Preferably, each of these lower movable rails can be moved in parallel with the corresponding upper movable rail in synchronization with each other.

As a preferable way of holding the upper movable rail, a chain is stretched between the front and rear upper sprockets, and the upper movable rail is held by the chain. In this case, in order to easily receive the load from the glass door, it is necessary to install rollers at both ends of each upper movable rail, and to make these rollers roll into contact with the upward supporting surface provided on the fixed member. Good.

In order to prevent large bending stress from acting on the movable rails, an auxiliary rail is provided above the upper movable rail that extends back and forth, and each of the upper movable rails is movably supported by this auxiliary rail. is preferable.

[Function] With this configuration, when all the glass doors are suspended and supported by the upper movable rail, these glass doors are arranged in parallel at predetermined intervals in the thickness direction, making it compact. Takes stored form. In this state,
There is no glass door on the front of the case body,
The front of the back wall of the case body can be used as a wall for open exhibition.

From this state, if you place the first upper movable rail adjacent to one end of the upper fixed rail and press the first glass door, which is suspended and supported by the upper movable rail, to the side, the glass door will
The upper fixed rail can be moved below. Next, all the upper movable rails are moved in parallel with the other glass doors, and when the second upper movable rail is adjacent to one end of the upper fixed rail, the second glass door is moved from below the upper movable rail to the upper fixed rail. It can be moved under the rail. Similarly,
All the glass doors supported by the upper movable rail can be moved below the upper fixed rail. In this way, a glass door is placed on the front of the case body, allowing conventional display.

On the other hand, the lower edge of each glass door placed on the front of the case body engages with the lower fixing rail and is held backwards than the upper edge, so the entire glass door is tilted slightly forward and supported for suspension. A force is generated that tries to rotate the mechanism forward due to its own weight using the mechanism as a fulcrum. Therefore, the force acts as a pressing force, and as a result of bringing the glass doors into contact with the lower fixed rail, all the glass doors are positioned flush along the lower fixed rail.

Moreover, since each glass door is in a suspended state, the gravitational force acting on the glass door acts in a direction that reduces warping of the glass door. Therefore, it is possible to reasonably and effectively improve the continuity of the surfaces of a plurality of glass doors arranged flush.

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

In addition, if the case body is equipped with a door holding mechanism, by pressing the movable member against the glass door placed on the front of the case body, the pressing force is used to suspend the glass door using the support mechanism as a fulcrum. As a result, all the glass doors are positioned flush along the fixing member. Furthermore, in this case, by releasing the door holding mechanism, the lower edge of the glass door can be left hanging due to its own weight, allowing smooth operation when moving it along the upper fixed rail. It is possible to secure it.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 10.

The lower sliding rails 71 to 710 that passed through the adjacent position are
It goes around the front lower sprocket 83a and reverses to the rear. When the operating handle 86 is reversed, the chains 82, 84 operate in the opposite direction, and the upper and lower movable rails (61, L) to (6zo-7□) operate in the opposite direction.
0) will result in a synchronous translation backwards.

With this kind of configuration, as shown in Figure 9,
All glass doors 2,~2□. The upper movable rail 6,~61
0, these glass doors 2, to 210 are arranged in parallel at predetermined intervals in the thickness direction, and are compactly stored. In this state, the glass doors 21 to 2+o do not exist on the front surface of the case body 1A, and the front surface of the back wall 15 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 61.71 are placed adjacent to one end of the upper and lower fixed rails 3.5, and the first glass door 2 that is suspended and supported by the upper movable rails 61 is placed adjacent to one end of the upper and lower fixed rails 3.5. , to the side, the glass door 21 can be moved to the upper fixed rail 3.
It can be moved down. Next, all the upper and lower movable rails (60, 71) to (6, ., 7, .) are translated in parallel with the other glass doors 22 to 21o, and the second set of upper and lower movable rails 6□, 72 upper, lower fixed rail 3.5

The glass doors 2, to 210 are arranged flush on the front of the case body IA, allowing for conventional exhibitions.

In this way, the lower edges 2b of the glass doors 2, to 210 disposed on the front surface of the case body IA engage with the side wall portion 51 of the lower fixed rail 5, and are held rearward than the upper edges 2a. As a result, the entire structure assumes a slightly forward-leaning posture, and a force is generated that tends to rotate forward due to its own weight using the support portion of the suspension rod 42 in the suspension support mechanism 4 as a fulcrum. Therefore, the force becomes a pressing force, and the glass doors 2□~2. comes into contact with the side wall portion 51, and as a result, all the glass doors 2, to 2□. are naturally positioned flush along the lower fixed rail 5. Moreover, since each of the glass doors 21 to 210 is in a suspended state, the glass doors 21 to 2. The gravity acting on the glass door 2,
~2. It acts in the direction of reducing warpage. Therefore, it is possible to reasonably and effectively improve the continuity of the surface in such a normal display state.

To open the case body IA again, the following operations can be performed in reverse. In addition, if it is necessary to illuminate the exhibits placed on the exhibition floor 18 or suspended from the back wall 15, appropriate lighting equipment can be provided on the ceiling wall 17 and the exhibition floor 18. , the lighting equipment can be easily shared between regular exhibitions and open exhibitions.

Although one embodiment of the present invention has been described above, it is also effective to position the glass doors 21 to 210 using the door holding mechanism 150 shown in FIG. 11.

In what is shown in the figure, both side walls 151 of the lower fixed rail 105 are arranged so that the center of the rail groove 152 is on the perpendicular line p drawn from the center of the opening 32 of the upper fixed rail 3, and A hinge 180 is attached to the front edge of the exhibition floor 18.
A movable member 180b is rotatably pivoted by the movable member 180b, and when the movable member 180b is in the set position, its front edge touches the elastic body 18.
It is set so that it can come into contact with the glass doors 21-210 via 0c and press the glass doors 21-210 forward.

Further, the front side wall portion 151 includes a glass door 2 pressed by the movable member 180b as a fixed member of the present invention,
-2io is extended to a position where it can be effectively stopped and supported, and an elastic body 151a is attached to the abutting portion. However, with such a configuration, the glass doors 2, ~2,
. can be fixed along the side wall portion 151,
Glass doors 2, - 2, similar to the previous embodiment. It becomes possible to perform a flush positioning function against the surface. Moreover, according to this structure, by releasing the set of the movable part 180b, the lower edges 2b of the glass doors 21 to 210 can be released in a state where they are hanging down due to their own weight. ~2
When moving 10 along the upper fixed rail 3, smooth operation can be ensured. Also, the 12th
As shown in the figure, a pair of detachable fittings 43 are attached to the suspension rod 42 via connecting fittings 48, and a clamp 44 is engaged with each of these detachable fittings 43, so that the center of the upper edge of the glass doors 21 to 210 is The parts may also be held together. Glass door 2,~2,. If the glass door is a large one, a pair of suspension support mechanisms 4 is provided as shown in FIG. 13 and FIG. It is also practically effective to suspend and support the vicinity. In this case, since each suspension support mechanism 4 is provided with a height adjustment means 46, each glass door 2, to 21
A slope of 0 can be easily corrected. Moreover, the clamp 44 is
In addition to constructing a single suspension support mechanism for each suspension support mechanism 4 as shown in FIG. 13, it is also possible to construct a plurality of suspension support mechanisms as shown in FIG. 14.

Furthermore, as the clamp, one shown in FIG. 15 can also be used. These four clamps are for glass door 2, ~
21L) are provided with through holes 2c in the thickness direction, and elastic fitting bodies 49a are press-fitted from both sides, and into these elastic fitting bodies 49a,
The clamping force of the bolt 49c is applied via the mounting bracket 49b. Furthermore, if the traveling body 41 has the wheels 41c pivoted at different positions as shown in FIG. 16, the upper fixed rail 3 and each upper movable rail 61
~ When crossing the rail joint with 610, the four wheels 41c
Since three of them can be grounded at all times, it is effective as a rattling prevention means. 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 storage section.

[Effects of the Invention] Since the present invention has the above configuration, 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.

Further, according to the present invention, by transferring the required number of glass doors to the storage section and suspending and supporting them on the vertical movement rail, it becomes 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, each glass door is suspended and supported on the upper fixed rail or upper movable rail via a suspension support mechanism, so even if the glass door is warped due to manufacturing distortion, etc., the warpage will be avoided. This will tend to be corrected by the load of the glass door itself. Therefore, even when using a glass door that has not been subjected to anti-glare treatment such as surface coating for clear visibility, there is less disturbance caused by reflections from lighting, etc., improving visibility and improving the case itself. can enhance the dignity of

In particular, when each glass door is suspended and supported under the upper fixed rail at the installation position, the lower edges thereof engage the lower fixed rail in a forward-leaning position, and as a result, the lower fixed rail engages with the lower fixed rail. It will be positioned flush along the line. This makes it possible to easily adjust the appearance of the display case by simply transporting it to a predetermined position without requiring any separate operations. Furthermore, since such a structure increases the degree of sealing of the glass door, it also serves as a means to prevent dirt and dust from entering the display case. Furthermore, the above-mentioned problems caused by reflections from lighting, etc. generally tend to increase as the size of the glass door increases. Since it becomes difficult for the viewer to fall into the line of sight at the viewer's feet, there will be an increase in the number of cases where better visibility can be obtained.

In addition, when aligning the front surface of a glass door that is suspended and supported on the upper fixed rail with the door holding mechanism, it is necessary to press the movable member, but the door holding mechanism must be released. This allows the lower edge of the glass door to be left hanging due to its own weight. For this reason, it is possible to ensure smooth operation compared to the above-mentioned configuration in which the lower edge of the glass door slides into contact with the fixed rail.

Furthermore, in addition to the above-mentioned basic effects, the present invention provides the following effects. First, in the past, the lower part of the exhibition floor was constructed with a so-called strainer wall structure in order to support the load of the glass door and the load of the exhibits. If the exhibition floor is supported by the top frame, the exhibition floor can be sufficiently supported by the floor frame extending from the pillars, so that the space below the exhibition floor can be effectively used as a storage space or the like. Additionally, if you use a suspension support mechanism that allows the glass door to swing in the width direction to some extent, it will be possible to force the side edges of adjacent glass doors to come into close contact with each other in the display state. By using a suspension support mechanism that allows some degree of rocking in the thickness direction of the glass door, it is possible to prevent excessive force from being applied to the clamping portion of the glass door, or to prevent the glass door from being placed in an exhibition state. This makes it possible to easily adjust the surface level of the glass door.Furthermore, if the rail drive mechanism is constructed as in the illustrated embodiment, multiple sets of lower movable rails can be used. With a simple configuration, it is possible to reliably move synchronously and parallelly, and it is possible to quickly switch the display mode with a simple operation.
