[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 equipped with a transparent glass plate 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 merely a sliding door type, it is necessary to overlap the side edges of the adjacent door plates, so it is not possible to arrange a plurality of door plates flush and close due to the structure, In addition, the view is partially obstructed and the viewer cannot give a good impression.

[0003] Therefore, the door plate is arranged flush, the lower end of one of the adjacent door plates is movably grounded on a lower movable rail that can move back and forth, and the upper edge of the door plate can move back and forth. The upper movable rail is held so as not to fall down, the door plate is moved in the front-rear direction via the suction handle, etc., and then from that position to the position where it overlaps the front or back of the adjacent door plate along the width direction A display case has been developed in which the front surface of the case body can be opened by moving the display case to the front.

[0004]

However, in such a configuration, since the posture of the door plate largely depends on the supporting positions of the upper and lower movable rails, the door plate must be vertically moved if both movable rails are not completely aligned. Can not hold in posture. In addition, since the door plate receives a reaction force from the lower movable rail and a compressive force acts everywhere, it is likely to bend in the surface direction, and when the door plate is made of glass, it may be broken in an earthquake or the like. is there. Therefore, it is difficult to arrange the doors flush with each other with high vertical accuracy and to maintain the same level once, which has been difficult in enhancing the display case.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention holds a door plate so that a compressive force does not act on the door plate and does not hinder the front-rear movement of the door plate. , To effectively enhance the tone of the entire display case.

3 and 4, in order to synchronously drive the upper edge 3a and the lower edge 3b of the movable door plate 3 in the front-rear direction.
As shown in FIGS. 5, 8 to 11, the ladder chain 71
, A chain case 73 accommodating the rotating member 72, a flexible long transmission member 74, a conversion section 75, and a drive mechanism 7 including a handle 76 as a drive source.
The ladder chains 71 are provided at two positions on the left and right sides near the upper edge 3a and the lower edge 3b of the movable door plate 3 in a state of being partially accommodated in the chain case 73, and are shown in FIGS. 10 and 11. As described above, a large number of chain elements 71a are connected by a connecting member 71b, and when the chain element 73 is extended backward from the chain case 73, the chain element 71a is linear and can transmit an urging force in the linear direction. When being drawn into the case 73, it can be wound in one direction while transmitting the traction force in a linear direction. The rotating member 72 is a sprocket that meshes with the ladder chain 71, and
The ladder chain 71 can be unwound or wound up from the chain case 73 by forward and reverse rotation of the rotary member 72. Long transmission member 74
Is a tube 74a in which a wire cable 74b having a thread groove is housed so as to be able to advance and retreat in the longitudinal direction. This long transmission member 74 is disposed in the upper decorative cover 15 as shown in FIGS. After passing through each of the provided chain cases 73 and drawing around, it is pulled in behind the opening / closing door 16x provided in a part of the lower decorative cover 16, and subsequently passes through each of the chain cases 73 disposed on the lower decorative cover 16. I'm going around. Tube 74a is the chain case 7
3, 73, or between the chain case 73 and a handle box 76a described below,
The orbital distance b is kept constant, and the longitudinal moving force of the wire cable 74b is prevented from being bent and deformed halfway. In the chain case 73 and the handle box 76a, the long transmission member 74 has the tube 74a removed, and the wire cable 74b is exposed. The conversion unit 75 is configured by meshing a gear 75a, which is rotatably attached to the rotating member 72 with the axis o coincident with the rotating member 72, and the wire cable 74b in a rack and pinion shape, and the wire cable 74b is a tube. When the ladder chain 71 moves forward and backward in the longitudinal direction, the moving force is converted into the rotational force of the gear 75a, and the ladder chain 71 is fed or wound. The handle 76 is
A sprocket (not shown) is mounted in the handle box 76a and is disposed near the lower decorative cover of the door plate 2x (the fixed door plate in this embodiment) adjacent to the right side of the fixed door plate 2. The wire cable 74b is engaged with the wire cable 74b, and when the handle 76b of the handle 76 is rotated forward and backward, the wire cable 74b can be moved in the longitudinal direction in the tube 74a. In this case, the operation of the handle 76 causes the upper and lower wires of the wire cable 74b to move in the opposite directions as illustrated by arrows in FIGS. 3 and 5, but the ladder chain 71 The conversion direction of the conversion unit 75 is defined so as to perform the unwinding and winding operations that match at the upper part and the lower part. The extension end 71c of the ladder chain 71 is connected to a movable part such as the movable rails 51 and 61 and the linear motion guides 52 and 62 that are movable back and forth via a driving force transmitting member 71x.

When the drive mechanism 7 is operated, the upper and lower movable rails 51 and 61 are appropriately stopped by a stopper or the like so that the ends of the upper and lower movable rails 51 and 61 stop at a position corresponding to the ends of the adjacent auxiliary fixed rails 41 and 42. Regulation means are provided. At that time, at the end of the upper movable rail 51 and the end of the auxiliary fixed rail 41, inclined end faces 51m and 41m that are inclined with respect to the direction orthogonal to the rail are formed as shown in FIG.
The inclined end surface 51m of the upper movable rail 51 moved forward is brought into contact with or extremely close to the inclined end surface 41m of the adjacent auxiliary fixed rail 41 so that the rails are connected to each other. The upper and lower decorative covers 15 and 16 are attached to bases 51x and 61x driven by linear motion guides 52 and 62 so as to be able to move in the front-rear direction together with the movable door plate 3 as shown in FIGS. It is.
These decorative covers 15 and 16 are provided with two widths that can simultaneously cover the fixed door plate 2 and the movable door plate 3 and move back and forth with the movable door plate 3 as described above. In order to avoid a cantilevered support state, as shown in FIG.
Linear motion guides 152 and 162 and a ladder chain 171 similar to those for the movable door plate 3 are provided at the locations so that only the guides and driving of the decorative covers 15 and 16 are performed. Of course, these decorative covers 15, 16
The can be attached to another part as long as it is a part movable back and forth together with the movable door plate 3.

Next, the handling method of this embodiment will be described. First, as shown in FIG. 1, when the cover 16x is opened and the handle 76b of the handle 7 is operated from the closed position where the fixed door plate 2 and the movable door plate 3 are continuously flush with each other, as shown in FIG. The wire cable 74b in the long transmission member 74 moves in the direction indicated by the arrow in FIGS. 3 and 5, and the ladder chain 71 associated with the wire cable 74b is drawn into the chain box 73. As a result, as shown by arrows and imaginary lines in FIGS. 5, 8 and 9, the upper movable rail 51 and the lower movable rail 61 have auxiliary fixed rails 41 and 42 (FIG.
And FIG. 6) to the position corresponding to the end of the movable door plate 3.
It is pulled out while holding. At this time, the upper and lower decorative covers 15 and 16 are also pulled out in conjunction with each other. When the urging force in the right direction in front view is applied to the movable door plate 3 from the position via a suction handle or the like, the movable door plate 3 rolls the wheels 53 a of the moving body 53 on the upward surface 51 c of the upper movable rail 51. 6 and 7, the roller 63a of the attachment 63 is moved along the upper and lower movable rails 51 and 61 while being in contact with the side wall 61a of the lower movable rail 61 as necessary. As shown by the line, the vehicle enters the adjacent auxiliary fixed rails 41 and 42. Then, in the state shown in FIG. 2 in which the movable door plate 3 has moved to a position substantially matching the front surface of the adjacent fixed door plate 2, the front opening 1a of the case main body 1 corresponding to the portion where the movable door plate 3 was disposed. Is opened. When the reverse operation is performed, the display case returns to the closed state shown in FIG. 1 again.

As described above, the display case of this embodiment can improve the viewing convenience by holding the movable door plate 3 in the closed position flush with the fixed door plate 2 when necessary. By pulling out the movable door plate 3 by the operation and moving it in the width direction, it is possible to easily put the exhibit in and out. And
In this embodiment, the movable door plate 3 is suspended and supported by the upper support mechanism 5 so as to be movable in the width direction, and the upper edge 3a of the movable door plate 3 is synchronized with the lower edge 3b via the upper support mechanism 5 in the front-rear direction. The movable door plate 3 assumes the most stable state in a vertical posture in which the center of gravity is located immediately below the upper edge 3a by its own weight. For this reason, high vertical accuracy can be given to the movable door plate 3, and a safe holding state can be ensured, and at the same time, the appearance of the display case can be improved. Further, if the movable door plate 3 is suspended and supported as described above, no compressive force acts on the door plate 3, so that there is an inconvenience that the glass plate bends in the surface direction or the glass is broken at the time of an earthquake or the like. Effective avoidance can also improve reliability. Further, since the driving mechanism 7 is provided to drive the upper edge 3a and the lower edge 3b of the movable door plate 3 back and forth in synchronization, the movable door plate 3 is tilted as if pushing or pulling a curtain. The display case can be opened and closed stably and safely and smoothly.

In addition, in this embodiment, the lower edge 3 of the movable door plate 3
b is also supported by the lower support mechanism 6, and the lower support mechanism 6 is simultaneously driven by the drive mechanism 7 in conjunction with the upper support mechanism 5, so that synchronization can be achieved with high accuracy. The effect can be made effective. Specifically, the upper support mechanism 5 includes an upper movable rail 51 and a moving body 53, and the moving body 53
, The upper edge 3a of the movable door plate 3 is suspended and supported, so that the suspension structure of the movable door plate 3 and the mobility can be suitably compatible. Further, since the lower support mechanism 6 is composed of the lower movable rail 61 and the auxiliary body 63, and the auxiliary body 63 is suspended from the lower edge 3b of the movable door plate 3, the mobility of the movable door plate 3 is impaired. Therefore, the supporting state of the lower edge 3b can be ensured.

In particular, as these more specific structures,
An upward facing surface 51c is formed on the upper movable rail 51,
Is provided with a wheel 53a that can roll around a horizontal axis m along its upward surface 51c, the lower movable rail 61 is formed in a channel shape, and the auxiliary body 63 has a vertical axis along its side wall 61a. Since the roller 63a that can freely rotate around n is provided, the movable door plate 3 can be supported by a simple structure.

Furthermore, since the upper and lower movable rails 51, 61 are supported by the linear motion guides 52, 62, the movable rails 51, 61 can be moved very smoothly back and forth. On the other hand, in the present embodiment, the drive mechanism 7 is of a ladder chain type, and the ladder chain 71 is disposed movably in the vicinity of the upper edge 3a and the lower edge 3b of the movable door plate 3 so as to be movable back and forth. Since the movable parts 5 and 6 are driven, the drive system can be made lightweight and can be mounted compactly in the case body 1.

In order to drive the ladder chain 71, a rotary member 73 for winding and unwinding is provided, while a flexible long transmitting member 74 is employed to reduce the driving force in the longitudinal direction. The transmission is performed through the operation, and the transmission end converts the rotation to the rotation of the rotary member 73 via the conversion unit 75. Therefore, the long transmission member 74 can be freely routed into the case main body 1, and the design is improved. The degree of freedom can be dramatically increased. In addition, a manually operable operating handle 76 is used as a drive source, and the operating handle 76 is
Is disposed near the lower edge 2b of the movable door plate 3 even if the display case is large.
The whole can be easily and reliably moved back and forth.

Further, the upper edge 3a and the lower edge 3 of the movable door plate 3
b, the decorative covers 15 and 16 are placed at positions where
Since it is attached and arranged so as to be able to move back and forth together with the movable door plate 3, it is possible to save the trouble of separately opening and closing the decorative covers 15 and 16 before and after the movement of the movable door plate 3 to prevent interference.
Operability can be more effectively improved. Further, as a configuration for moving the movable rail 3 in the front-rear direction and then moving it to a position where the movable rail 3 overlaps the adjacent fixed door plate 2, the ends of the movable rails 51 and 61 moved in the front-rear direction match. Since the auxiliary fixed rails 41 and 42 are arranged near each of the upper edge 2a and the lower edge 2b of the adjacent fixed door plate 2, the structure is simple. Since the end of the rail 51 and the end of the upper auxiliary fixed rail 41 are made continuous through the inclined end surfaces 51m and 41m, the moving body 53 has a smaller length than the case where the end is orthogonal to the rail direction. Wheel 5
The rail joint can be made to gradually pass through 3a, and even if there is a slight gap or displacement at the joint, the running can be stabilized and the operation failure can be effectively avoided.

The specific configuration of each section is not limited to the illustrated embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, an electric drive mechanism may be employed as the drive source, and the door plate may be moved backward from the closed position and opened. The moving member and the attachment member of the rail support mechanism may have other configurations.

[0029]

The present invention is embodied in the form described above and has the following effects. That is, the display case of the present invention suspends and supports the door plate movably in the width direction by the upper support mechanism, and drives the upper edge of the door plate in the front-rear direction in synchronization with the lower edge via the upper support mechanism. As a result, the vertical weight can be obtained by using the weight of the door plate to achieve high vertical accuracy, stabilizing the holding state and improving the appearance, and preventing the compressive force from acting on the door plate to prevent bending in the surface direction. It is possible to realize a highly reliable display case that is hardly broken even with glass. Moreover,
Since a drive mechanism is provided to drive the upper and lower edges of the door plate synchronously, even if the movable door plate is suspended and supported, it can be prevented from tilting as if pushing or pulling a curtain, and the display case Safety at the time of opening and closing operation can be ensured.

In addition, when the lower edge of the movable door plate is also supported by the lower support mechanism, and the lower support mechanism is simultaneously driven by the drive mechanism in conjunction with the upper support mechanism, synchronization can be achieved with high precision. Therefore, the above effects can be achieved. In addition, if the upper support mechanism is composed of an upper movable rail and a movable body, and the movable body is supported by suspending the upper edge of the door plate via a suspending rod, the suspension structure of the door plate and the mobility can be improved. The lower support mechanism is composed of a lower movable rail and a subjunction body, and if this subjunction is vertically installed on the lower edge of the movable door plate, the lower edge can be supported without impairing the mobility of the door plate. The state can be assured.

In particular, as these more specific structures,
If an upper surface is formed on the upper movable rail to roll the wheels of the moving body, and the lower movable rail has a side wall so that the roller of the attachment body is rolled, the simple structure of the door plate A good support state can be realized. further,
If the upper and lower movable rails are supported by the linear motion guide, the movable rails can be moved forward and backward very smoothly.

On the other hand, the driving mechanism is of a ladder chain type, and this ladder chain is disposed movably in the vicinity of the upper edge and the lower edge of the movable door plate to drive the movable part of the upper and lower support mechanisms. By doing so, the drive system can be made lightweight and can be mounted compactly in the case body, facilitating design and manufacture. In addition, in order to drive the ladder chain, a rotatable member for winding and unwinding is provided, while a flexible elongate transmission member is employed to transmit the driving force through an elongating and retracting operation in the elongate direction. By converting the rotation operation of the rotary member at the transmission end via the conversion unit, the long transmission member can be freely routed into the case main body, and the degree of freedom in design can be greatly increased. If a manually operable operating handle is used for the drive source and the operating handle is arranged near the lower edge of the door plate, running costs can be reduced, and even if the display case is large, The movable door plate can be easily and reliably moved back and forth by operating from a handy position.

Furthermore, if a decorative cover is attached and disposed so as to be able to move back and forth together with the door plate at a position that conceals the vicinity of the upper edge and the lower edge of the door plate, the decorative cover is separately provided before and after the door plate moves. The labor for opening and closing the display case can be omitted, and the operation for opening and closing the display case can be simplified. In addition, as a configuration for moving the door plate to the adjacent door plate side, auxiliary fixed rails in which the ends of the movable rails moved in the front-rear direction coincide with each other are disposed near both upper edges of the adjacent fixed door plate. If this is done, the structure becomes simple, and in particular, if the end of the upper movable rail and the end of the upper auxiliary fixed rail, on which the load of the movable door plate mainly acts, are made continuous through the inclined end surface, the seam will be somewhat It is possible to smoothly move the moving body even if there is a gap or a displacement between them, thereby preventing a malfunction from occurring.
