Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display case used for displaying various exhibits for viewing.

[0002]

2. Description of the Related Art For example, as a display case used in a museum or an art gallery, at least a transparent glass door or the like is generally mounted on the front surface, and the door plate can be opened and closed in a sliding door manner. There are many. At that time, if you use a simple sliding door type, the edges of adjacent door plates will overlap each other, impairing the appearance and partially blocking the view,
There is a problem that the viewer cannot be given a good impression. Therefore, the fixed door plate and the movable door plate are arranged adjacent to each other, and the fixed rail is arranged on the front surface of the fixed door plate so that the movable door plate can be pulled out from the closed position and moved onto the fixed rail to be superposed on the fixed door plate. Improved products have been developed.

[0003]

However, most of these improved products have a difficulty in the operation of pulling out the movable door plate and have a complicated structure. For example, fixed rails are installed side by side in front of the upper and lower edges of the fixed door plate, and the entire rail that supports the upper and lower edges of the movable door plate is slidable in the front-rear direction by a rail pulling mechanism. In the case where the movable rails can be pulled out in parallel to the position matching the fixed rail, it is difficult to operate the upper and lower movable rails in a synchronous manner, and the entire door board easily falls into a state in which it tilts forward and backward. Therefore, in addition to the difficulty in operability, a large operating force is required to support and correct the movement of the center of gravity at the time of tilting, and it is conceivable that the doorboard may tilt freely to induce a dangerous state.

In order to overcome this, rails supporting the upper and lower edges of the movable door plate can be turned by a rail turning mechanism, and the movable rail is horizontally moved from a closed position to a rail mating position continuous with the end of the fixed rail. In the case of a swingable support, the rigidity of the door plate can be used to ensure the synchronized rotation of the upper and lower movable rails, and the movement of the center of gravity can be eliminated, but various mechanical components that make up the rail rotation mechanism are required Therefore, the structure is complicated, and there is a limit to increase the reliability and durability of the operation.

The present invention has been made in view of these problems, and an object thereof is to provide an exhibition case in which a movable door plate can be opened / closed smoothly, safely and surely with a simple structure. There is.

[0006]

In order to achieve the above object, the present invention employs the following configuration.

That is, the display case of the present invention has a general structure as this type of display case. In the display case, fixed rails provided in parallel near the upper and lower edges of the fixed door plate and the movable door plate are fixed. A first support member attached to at least the lower edge side near the rail-side end, and an upper edge and a lower edge near the fixed rail-side end are supported directly or through the first support member and these upper edges. And upper and lower first guide rails for guiding the lower edge through a sliding action in the front-rear direction from a closed position to a position continuous with the end of the fixed rail,
The second support member attached to at least the lower edge side of the movable door plate near the end opposite to the fixed rail, and the upper edge and the lower edge near the end opposite to the fixed rail via the second support member or directly. When the first guide rail is in a position continuous with the end of the fixed rail, the upper and lower edges of the first guide rail are continuous from the closed position to the end of the first guide rail opposite to the fixed rail. It is characterized in that a second guide rail fixed to the upper and lower sides for guiding to a position is provided.

[0008]

In such a structure, when an operating force is applied in the thickness direction to the vicinity of the fixed rail side end of the movable door plate with the movable door plate in the closed position, the lower edge of the movable door plate passes through the first support member. Since it is supported by the lower first guide rail that is slidable in the front-rear direction, this lower edge is moved to a position continuous with the end of the fixed rail by the operation of the lower first guide rail. At this time, the corresponding upper edge also follows and moves to a position continuous with the end of the fixed rail through the operation of the upper first guide rail that is slidable in the front-rear direction. At this time, if the upper and lower first guide rails support the entire movable door plate, it is difficult to guarantee the synchronous operation of both guide rails, and it is easy to cause a temporal tilt in the front-back direction. However, these first guide rails only support one end side of the movable door plate, and the upper and lower edges on the other end side are guided by the fixed second guide rails extending substantially along the plane direction, Both the upper and lower edges on the other end side maintain a substantially vertical posture, and as a result, the verticality of the entire movable door plate is secured. That is, the operation force applied from the outside is transmitted to the upper edge and the lower edge by the rigidity of the door plate, and the movable door plate is kept in the upright posture with the second support member attached near the end portion on the side opposite to the fixed rail as a fulcrum. Will turn horizontally. Next, when an operation force is applied to the movable door plate in the plane direction, since the lower first support member reaches the end entrance of the fixed rail, the lower first support member starts to move in a direction substantially orthogonal to the above, and moves in the adjacent fixed rail. Enter. At this time, the corresponding upper edge part also follows and moves, and the upper and lower edges near the end part on the side opposite to the fixed rail also move along the second guide rail toward the end part of the first guide rail. Finally, when the upper edge and the lower edge near the end portions on the side opposite to the fixed rail pass through the first guide rail and enter the fixed rail, the movable door plate reaches a position where the movable door plate and the fixed door plate are substantially overlapped with each other. The front surface of the display case in which the movable door plate was disposed is opened. When closing the front surface, an operation reverse to the above may be performed.

The upper frame 6 is provided on the upper edge, the lower frame 7 is disposed on the lower edge, and the fixed door plate 3 is fixed in a vertical posture between the central portions of the upper frame 6 and the lower frame 7.

The fixed door plate 3 is, as shown in FIG. 3, provided with protective frames 9 and 11 on both upper and lower edges of a glass plate 8.
Protective frames 9 and 11 above and below the intermediate frames 12 and 1
It is fixed to the upper frame 6 and the lower frame 7 via 3a and 13b. Then, the upper and lower edges 3a of the fixed door plate 3,
The fixing rails 14 and 15 are laid in parallel with the fixed door plate 3 in the vicinity of 3b, specifically, the portions adjacent to the upper frame 6 and the lower frame 7, respectively, on the rear side of the fixed door plate 3. ing.

On the other hand, the movable door plate 4 adjacent to the fixed door plate 3 is, as shown in FIGS. 4 and 5, provided with protective frames 17 and 18 on both upper and lower edges of a glass plate 16 which is a transparent rigid body. As shown in FIG. 4, the upper edge 4a and the lower edge 4b near the ends on the fixed rails 14 and 15 side are the upper first support members 10 as shown in FIG.
The upper first guide rail 111 and the lower first guide rail 112 are supported via the first and lower first support members 102. Further, as shown in FIG. 5, the upper edge 4a and the lower edge 4b near the ends on the opposite side to the fixed rails 14 and 15 are connected to the upper second support member 201 and the lower second support member 202 to form the upper second
It is supported by the guide rail 211 and the lower second guide rail 212. In the case of this embodiment, the lower first support member 102 and the lower second support member 202 are wheels that are axially mounted around a horizontal axis, and the upper first support member 101 and the upper second support member 201 are vertical. It consists of a touch bearing mounted around the shaft. Further, the lower first support member 1
02 and the outer end side of the lower second support member 202 are provided with a touch bearing 303 axially mounted around the vertical axis. By the way, the upper first guide rail 111 and the lower first guide rail 112 described above are channel-shaped so that the first support members 101 and 102 can be rotatably fitted therein, as shown in FIGS. 4, 6 and 7. It is provided slidably in the front-back direction. Specifically, slits 6a, 7 extending in the front-rear direction are formed in the bottom plate portion of the upper frame 6 and the top plate portion of the lower frame 7.
a is open, the upper first guide rail 111 is connected to each other via the slit 6a and the retaining member 111a arranged above the slit 6a, and the lower first guide rail 112 penetrates the slit 7a. Hanging protrusion 112
a is pivotally attached to the operation end of the operation lever 113. When the operation lever 113 is rotated, the first support members 101 and 102 can be guided from the closed position shown by the solid line in FIG. 4 to the position shown by the imaginary line. At this position, as shown in FIGS. 6 and 8, each of the guide rails 111 (112) is fixed to the fixed rails 14 and 1.
5 is a position that can be continuous with the end portions 14a and 15a. Further, the upper second guide rail 211 and the lower second guide rail 212 are, as shown in FIGS.
The first guide rail 111 is a channel-shaped member in which the first and the second support members 202 and 202 can be rotatably loosely fitted, and the first support members 201 and 202 are obliquely left rearward from the closed position, specifically, when the first support members 201 and 202 are retracted. , 112 can be guided to a position continuous with the end portions 111b, 112b (see FIG. 8) of the first and second terminals 112, 112. In other words, between the fixed rails 14 and 15 and the second guide rails 211 and 212, the first guide rail 111,
112 is removable.

Next, the operation of the present embodiment configured as described above will be described. First, in the state where the movable door plate 4 is in the closed position adjacent to the fixed door plate 3 as shown in FIGS. 6 and 7,
When an operating force in the thickness direction indicated by arrow X in the figure is applied to the vicinity of the fixed rail side end portion of the movable door plate 4 through an appropriate handle or the like, the lower edge 4b of the movable door plate 4 has the lower edge 4b thereof as described above.
Since the lower edge 4b is supported by the lower first guide rail 112 that is slidable in the front-rear direction via the, the lower edge 4b is retracted backward by the operation of the lower first guide rail 112, and as shown in FIGS. The fixed rail 15 is moved to a position continuous with the end 15a. At this time, the corresponding support member 101 on the side of the upper edge is also moved through the operation of the upper first guide rail 111 which is slidable in the front-rear direction.
It follows and moves to a position continuous with 4a. At that time, if the upper and lower first guide rails 111 and 112 have a conventional structure in which the entire movable door plate 4 is supported, it is difficult to operate both guide rails 111 and 112 synchronously, and the center of gravity shifts. Although it is easy to lead to the tilting motion involved, in the present embodiment, these first guide rails 111 and 112 only support one end side of the movable door plate 4, and the upper and lower edges 4a and 4b on the other end side are substantially in the plane direction. Since it is guided by the fixed second guide rails 211 and 212 extending along the upper and lower edges, the upper and lower edges 4a and 4b on the other end side maintain a substantially vertical posture, and to that extent, the vertical posture on one end side is also maintained. The verticality of the entire movable door plate 4 is ensured. That is, the operating force X applied from the outside is transmitted to the upper edge 4a and the lower edge 4b due to the rigidity of the door plate, so that the movable door plate 4 remains in the upright posture and the second support members 201 and 202 near the end portions on the side opposite to the fixed rails are moved. It will turn horizontally as a fulcrum. In particular, the four touch bearings 101, 201, 303, 303 roll on the side wall of the rail to ensure an appropriate vertical posture of the movable rail 4. Next, when an operation force in the surface direction indicated by the arrow Y in FIG. 6 is applied to the movable door plate 4, since the lower first support member 102 is located at the entrance of the end portion 15a of the fixed rail 15, It begins to move in a direction substantially orthogonal to and enters the adjacent fixed rails 15 as shown in FIG. At this time, since the touch bearing 303 is located at the front end in the moving direction, the touch bearing 303 hits the side wall of the fixed rail 15 and exerts a guiding action to match the thickness direction center of the movable door plate 4 with the width direction center of the rail. And a collision between the ends of the fixed door plate 3 is reliably avoided. Touch bearing 1 which is the upper support member
The same applies to the relationship between 01 and the fixed rail 14,
The support member 101 also follows and moves into the fixed rail 14. Then, in synchronization with these, the upper and lower support members 201 and 202 near the end portions on the side opposite to the fixed rails also extend along the upper and lower second guide rails 211 and 212 to the end portions 111b and 112b of the first guide rails 111 and 112. 10 and then finally pass through these guide rails 111 and 112 to enter the fixed rails 14 and 15,
As shown in FIG. 5, the entire movable door plate 4 reaches a position where the movable door plate 4 is substantially overlapped with the fixed door plate 3, and the front surface of the display case body 1 in which the movable door plate 4 is disposed is opened. When closing the front surface, an operation reverse to the above may be performed. Although the operation described above is for the movable door plate 4 on the right side of the fixed door plate 3, the principle is the same for the movable door plate 4 on the left side and may be considered symmetrically.

As described above, the display case of this embodiment can open and close the front opening 2 of the case body 1 as needed.
The operating force applied to the upper and lower edges 4a and 4b of the glass plate 16 is simultaneously transmitted via the rigidity of the glass plate 16, and the upper and lower guide rails are partially movable only at one end sides 111 and 112 and at the other end side 211. , 212 is not movable, the movable door plate 4 always behaves in a substantially vertical posture until it is transferred to the fixed rail 3, and the center of gravity moves so that the verticality of the surface is impaired. Never. Therefore,
Even when the operating force X is relatively small compared to the conventional rail pull-out mechanism, the smooth operation of the movable door plate 4 can be ensured, and the problem that the movable door plate 4 tilts freely can be solved. it can. Such a stable behavior is exhibited even when the operation force Y is applied thereafter to move to the fixed rail 3 side. Further, structurally, since the movable part is limited to an extremely small area on one end side 111, 112 of the lower guide rail, it is much simpler than the conventional rail turning mechanism, and reliability and durability are improved. It also makes it possible to dramatically improve the performance.

The specific construction of each section is not limited to the above-mentioned embodiment. For example, in the above embodiment, the lower first and second support members 102 and 202 of the movable door plate 4 are used.
Although it is constituted by wheels, it may be constituted by other constitutions such as a ball bearing. Further, in the above embodiment, the upper edge ends of the movable door plate 4 are supported by the touch bearings 101 and 201 as the first and second support members, but a slider made of resin or the like having a low sliding resistance is attached. Can also cover,
If there is no problem, a protrusion may be integrally provided on the movable door plate 4 and the protrusion may be directly supported. Furthermore, although the movable door plate 4 is superposed on the back surface of the fixed door plate 3 in the above-mentioned embodiment, it may be superposed on the front surface side. Other specific configurations can be variously modified without departing from the spirit of the present invention.

[0017]

As described above, in the display case of the present invention, the upper and lower edges near the fixed rail side end of the movable door plate in the closed position are supported by the first guide rail which is slidable in the front-rear direction. The guide action of the first guide rail guides the upper edge and the lower edge of the movable door plate to a position continuous with the end portions of the adjacent fixed rails, and the movable door plate in the closed position near the non-fixed rail side end portion. Both upper and lower edges are supported by a fixed second guide rail, and the upper and lower edges of the movable door plate are guided along the second guide rail to a position continuous with the end of the fixed rail via the first guide rail. It is configured to obtain. Therefore, it suffices to adopt a movable rail in an extremely limited area, and it is not necessary to pull out the entire rail forward and backward or rotate it. Therefore, a large movable mechanism is not used, and a relatively small operating force is required. This makes it possible to open and close the movable doorboard easily, safely and smoothly. Therefore, the display case of the present invention can be superior in operability, safety, reliability, durability, cost performance, etc., to the opening / closing operation of the movable door plate.
