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 an exhibit or the like for viewing.

[0002]

[Prior Art] Display cases in museums, museums, etc.
Alternatively, a display case used as a showcase in an exhibition hall, a department store, or the like is generally provided with a transparent glass door or the like at least on the front surface so that the door plate can be opened and closed in a sliding door manner. At that time, if it is simply a sliding door type, since it is necessary to overlap the side ends of adjacent door plates, it is structurally impossible to arrange and close a plurality of door plates flush, In addition, the view is partially obstructed and the viewer cannot be given a good impression. Therefore, an improved product has been developed in which all door plates are made movable in the front-rear direction, and each rail has a so-called double rail structure in which two door plates can be simultaneously arranged.

[0003]

With such a structure, when the door is closed, the door plate can be supported on one of the double rails. When the door is opened, a specific double rail is pulled out and the door plate is supported by the rail. Can be moved to the adjacent double rail side. However, the normally empty rail of the double rail will be located ahead of the door plate when closed, and the upper and lower decorative plates project from the door plate to conceal this rail, and the appearance is poor in appearance. Has the disadvantage of becoming In addition, the double rail requires a rail width twice that of a normal rail, and since it is movable back and forth, the entire rail cannot be made compact and a large operating space must be secured for the display case. The problem arises that it must be done. Furthermore, when the double rail is moved in the front-rear direction, if there is a slight deviation between one rail and the other rail of the adjacent double rail, this becomes an obstacle, and the door plate is moved in the width direction. A problem that the rollers and the like do not advance smoothly is likely to occur. Such a defect is particularly noticeable in the case of the lower rail.

[0004]

According to the present invention, in order to solve the above-mentioned problems, in a display case, a door can be smoothly moved with a simple structure to open a front opening of a case body. In addition, in the closed position, all the door plates are flush with each other, and the decorative plate is not protruded.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The display case of the present invention is a glass plate which is arranged at a position where the front opening of the case main body is closed flush with the case main body at the closed position. And a plurality of door plates formed mainly of a transparent rigid body, etc., the door plate can be moved in the width direction along at least one of the upper edge or the lower edge of one of the adjacent door plates. And a guide rail extending continuously to at least an adjacent door plate for guiding the support member, and a front-rear direction between the closed position and a pulled-out position where the door plate is drawn forward together with the guide rail. A first guide mechanism for guiding the door plate so that the door plate can be freely moved in and out, and the door plate drawn forward through the first guide mechanism is adjacent to the door plate along the guide rail drawn forward at the same time. And characterized by being configured so as to move in the width direction until in front of the plate.

In such a configuration, at least one of the upper edge and the lower edge of one of the adjacent door plates is movably supported by the support member, and furthermore, the first guide member is used to move the door plate between the closed position and the drawn-out position. It is guided in the front and rear direction freely through the support member between the positions, so if you apply an operating force in the front and rear direction to the door plate, all the door plates will be displayed in the closed position where they are flush with each other Door plates arranged alternately in the width direction of the case are drawn out. Furthermore, since the first guide mechanism is provided with a guide rail that is continuous to an adjacent door plate, it is not necessary to join a plurality of rails together, and the guide plate is pulled out along the guide rail that is drawn at the same time as the door plate. Can be smoothly moved in the width direction to the front of the adjacent door plate to open the front surface of the case body. Therefore, it is not necessary to keep the rails at a position in front of the adjacent door plate, and a decorative plate for concealing the rails is arranged at a position substantially flush with the door plate, so that the appearance is sharp and clear and the viewer can enjoy it. A good impression can be given.

[0007] In order to support the load on the door plate and ensure more stable movement of the door plate, the guide rail is
It is desirable to arrange at least along the lower edge of the door plate. In addition, in order to achieve mechanical synchronization and simplify the structure when a large number of door plates are provided, the guide rails should be provided over substantially the entire length of the display case in the width direction. Is preferred.

Further, in order to be able to move the door plate adjacent to the door plate which can be freely moved in the front-rear direction to the rear of the door plate pulled out at the drawing position and to retract the door plate, it is necessary to set the door plate on the door plate. A support member comprising a fixed element fixed to the case body along at least one of the edge and the lower edge, and a movable element fixed to the door plate is provided, and the door plate is moved forward between the fixed element and the movable element. It is desirable to configure a second guide mechanism for supporting the door plate movably in the width direction to the rear of the door plate drawn out. Further, when the door plate is moved in the width direction with respect to the support member, the moving range is limited to a half width of the door plate in order to make the door plate cantilever and effectively prevent the door plate from falling off. It is effective to do so.

In order to make the door plate movable in the width direction with a simple configuration movable in the front-rear direction, a roller capable of rolling along the width direction of the door plate is provided on a support member for supporting the door plate. It is effective that the roller is guided by the guide rail so that the door plate can be moved in the width direction. In order to prevent the door plate from rattling in the front-rear direction and to allow the door plate to move smoothly in the width direction, the door plate is moved in the width direction together with the door plate which can be moved in and out in the front-rear direction. Along with disposing a guide plate extending over the door plate, an auxiliary roller is provided on the fixed part element of the door plate at a position adjacent to the door plate which can be freely moved in the front-rear direction. It is desirable that the plate is guided by the rotation of the auxiliary roller to simultaneously guide the widthwise movement of the door plate which can be freely moved in the front-rear direction. In such a case, the roller or the auxiliary roller can be rotated around a vertical axis so that the door plate can move relatively smoothly even if a slight displacement occurs between adjacent rails. Therefore, it is effective to easily overcome this deviation.

The simple structure of the first guide mechanism is a linear motion comprising a fixed portion fixed to the case body and a movable portion slidably provided on the fixed portion and supporting the guide rail. Preferably, a guide is provided, and the movable portion slides back and forth between the closed position and the withdrawn position with respect to the fixed portion so that the door plate can be freely moved in and out in the front-rear direction.

On the other hand, a simple configuration of the second guide mechanism includes a guide groove provided in one of the fixed element and the movable element, and a roller provided in the other of the fixed element and the movable element. Preferably, the rollers are guided by the guide grooves so that the door plate is movable in the width direction. Furthermore, in order to more stably support the door plate and to make its movement more stable, it is effective to dispose the support member on both the upper edge and the lower edge of the door plate.

As shown in (a) and (b), it is possible to move to the rear of the drawn out end door 21 on both sides. Further, as shown in FIGS. 12A and 12B, one end door plate 2
Move 1 to a position adjacent to the other end door plate 21,
By moving the central door plate 22 to the rear, the front opening 14 of the case body 1 can be opened to the maximum. When the door plates 21 and 22 move, the auxiliary rollers 84, 85, 324, and 424 rotate while being attached to the guide plate 83 and the auxiliary guide grooves 326 and 426. The backlash in the direction can be effectively suppressed. Further, since the upper guide rails 51 and 511 are not integrally continuous in the width direction of the case main body 1 like the lower guide rail 52, a slight displacement may occur. 2
Since the rotation axis h of the first upper roller 314 is in the vertical direction, the deviation can be easily overcome, and it is possible to smoothly advance to the adjacent upper guide rails 511 and 51 without difficulty. The range of movement of the central door plate 22 in both width directions is determined by a lower auxiliary roller 424 provided at a position close to both side edges 22d of the central door plate 22 and a stopper 427 provided substantially at the center of the lower auxiliary guide groove 426. The central door 22 is prevented from falling off by restricting it to approximately half the width of the door 22. In this manner, the display case A of the present embodiment has the drawer position Y
By moving each of the door plates 21 and 22 in the width direction, the front opening 14 of the case body 1 is opened, so that an exhibit can enter and exit the exhibition space S. When the doors 21 and 22 are returned to the flush closing position X, the above procedure may be reversed.

1 can be effectively supported, and the door plate 21 can be stably moved in the width direction. Further, according to the configuration of the lower guide rail 52, no seam occurs in the rail, and mechanical synchronization can be achieved and the configuration can be simplified. An upper roller 314 and a lower roller 413 are attached to the upper and lower support members 31 and 41 of the end door plate 21, and these rollers 314 and 413 are guided by the guide rails 51 and 52. The door plate 21 can be moved very smoothly in the width direction. In particular, in the case of this embodiment, the weight of the glass door plate 2 is several hundred kg, and if there is a seam in the rail, it may not be possible to get over it. Since the lower roller 413 is arranged and the mounting position of the lower roller 413 is set substantially directly below the end door plate 21, the load on the door plate 21 can be effectively supported, and the traveling can be smoothly stabilized.

Further, the supporting members 32, 42 disposed along the upper edge 22b and the lower edge 22c of the central door plate 22 at the position adjacent to the end door plate 21 are fixed to the roller holder 322 fixed to the case body 1. , 422 and door plate holders 321, 421 fixed to the door plate 22, between which upper and lower second guide mechanisms 71, 72 for supporting the door plate 22 movably in the width direction are provided. Therefore, the central door plate 22 can be moved in the width direction to the rear of the pulled out end door plate 21.

Are provided so that the guide plate 83 is guided by the auxiliary rollers 84 and 85 and moves in the width direction together with the end door plate 21 at the extraction position Y where the end door plate 21 is pulled out. Therefore, even when the door plate 21 overlaps with the central door plate 22, the end door plate 21 does not meander and can run stably. The auxiliary rollers 84 and 85 and the end door plate 2
Since the rotation axes j, o, h of the upper roller 314 are set in the vertical direction, the guide plate 83 and the auxiliary roller 84,
85, or even if a displacement occurs between the upper guide rail 51 of the upper part of the end door plate 21 and the upper guide rail 511 of the upper part of the central door plate 22 which are arranged so as to be continuous at the drawing position Y, The end door plate 21 can be easily moved in the width direction smoothly over this gap.

The upper and lower second guide mechanisms for moving the central door plate 22 in the width direction include guide grooves 325 and 425 and auxiliary guide grooves 32 formed in the door plate holding portions 321 and 421.
6 and 426, and the rollers 323 and 423 and the auxiliary rollers 324 and 424 disposed on the roller holding portions 322 and 422 and rotating on the inner surfaces of the respective grooves. Can be obtained. Further, since the stopper 427 is provided at a substantially central portion of the lower auxiliary guide groove 426, and the moving range of the central door plate 22 is set to be approximately half the width, the door plate 22 can be easily prevented from falling off. .

The specific configuration of each section is not limited to the above-described embodiment. For example, the same effect as in the above embodiment can be obtained even when the relationship between the mounting positions of the rotation shafts of the roller and the auxiliary roller is reversed. In addition, even when the configuration of the upper and lower guide rails is reversed, the guide plate that moves in the width direction together with the end door plate rotates around the vertical axis waiting behind the adjacent central door plate. If it is configured to be guided by the rotation of the auxiliary roller, the end door plate can be easily moved forward of the central door plate. In addition, even when the number of the door plates 2 is other than three, if one of the adjacent door plates 2 is configured to be the door plate 2 that can freely enter and exit in the front-rear direction, the above-described embodiment can be used. The same effect as described above can be obtained. Various modifications can be made to other configurations without departing from the spirit of the present invention.

That is, in the display case of the present invention, at least one of the upper edge or the lower edge of one adjacent door plate is movably supported by the support member, and any one of the adjacent door plates is further moved. Since the first guide mechanism guides the door plate between the closed position and the drawn-out position via the support member so that the door plate can be moved in and out of the front and rear directions, when an operation force is applied to the door plate in the front and rear direction, all the door plates are flush. From the closed position, doors arranged alternately in the width direction of the display case can be pulled out. Further, since the first guide mechanism is provided with a guide rail that continues at least to the adjacent door plate, the door plate is moved in the width direction to the front of the adjacent door plate along the guide rail that is drawn out simultaneously with the door plate. And the front surface of the case body can be opened. Therefore, it is not necessary to make the rails stand by in front of the case body in advance, and it is possible to avoid running obstacles due to rail joints.

When the guide rails are arranged along at least the lower edge of the door plate, the load on the door plate can be effectively supported, and more stable movement of the door plate can be ensured. In addition, if the guide rails are disposed over substantially the entire length in the width direction of the display case, mechanical synchronization can be achieved and the configuration can be simplified when a large number of door plates are disposed. .

Further, a fixed element fixed to the case body along at least one of an upper edge and a lower edge of the door plate at a position adjacent to the door plate which can be moved in and out in the front-rear direction, and a movable element fixed to the door plate. A second guide mechanism is provided between the fixed element and the movable element to support the door plate movably in the width direction to the rear of the door plate drawn forward. Can retract the door plate in the width direction to the rear of the door plate pulled out to the drawing position.
Furthermore, when moving the door plate in the width direction with respect to the support member, if the movement range is limited to a half width of the door plate,
Even if the door plate becomes cantilevered, it is possible to effectively prevent the door plate from falling off from the support member.

A roller that can roll along the width direction of the door plate is provided on a support member that supports the door plate that can be moved in and out in the front-rear direction. The roller is guided by the guide rail to move the door plate in the width direction. When movable, the door plate can be moved smoothly in the width direction with a simple configuration. A guide plate extending in the width direction of the door plate is disposed at a position where the door plate moves in the width direction together with the door plate movable in the front-rear direction, and the fixing of the door plate at a position adjacent to the door plate movable in the front-rear direction is performed. When an auxiliary roller is provided in the partial element, when the adjacent door plates overlap at the drawing position, the guide plate is guided by the rotation of the auxiliary roller,
If it is configured to simultaneously guide the widthwise movement of the door plate that can be freely moved in the front-rear direction, it is possible to prevent the door plate from rattling in the front-rear direction and to make the movement in the width direction smoother. it can. In such a case, if the roller or the auxiliary roller is configured to be rotatable about a vertical axis, even if a slight displacement occurs between adjacent rails, the displacement can be easily overcome. The operation failure caused by the divided rail can be eliminated.

The first guide mechanism includes a fixed portion fixed to the case body side and a movable portion slidably provided on the fixed portion and supporting the guide rail. By sliding the door plate back and forth in the front-rear direction by sliding the door plate back and forth between the closed position and the draw-out position with respect to the fixed portion, a door plate moving mechanism that is easy to take an electric synchronous drive with a simple configuration. Can be configured.

The second guide mechanism may include a guide groove provided on one of the fixed element and the movable element, and a roller provided on the other of the fixed element and the movable element. Thus, a simple and stable moving mechanism can be configured. Furthermore, if the support member is disposed on both the upper edge and the lower edge of the door plate,
It is possible to more stably support and move more stably.
