Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter device with a door mechanism having a shutter curtain provided with a door mechanism, and can be used, for example, in a shutter device for disaster prevention for fire prevention, smoke prevention, etc. It can be suitably used as a shutter device for a large opening that partitions a space having a large sectional width.

[0002]

BACKGROUND ART Generally, a shutter device for various purposes for partitioning a space by moving a shutter curtain up and down is provided in a doorway of a building or in the middle of an aisle to prevent fire and smoke. The disaster prevention shutter device is one of them.

Conventionally, as such a disaster prevention shutter device, a device provided with a metal (iron) shutter curtain has been used. In addition, since the shutter device for disaster prevention equipped with a metal shutter curtain has a Ministry of Construction notification (Notification No. 2564 of 1973) based on Article 112, paragraph 14, item 4 of the Building Standard Act enforcement order, Those with a length of 5 m or less were standard specifications. Therefore,
In the case of a so-called large opening where the opening in the building where the shutter device for disaster prevention is to be installed (the cross-sectional width of the space to be partitioned by the shutter curtain) is large, usually a center pillar with a guide rail is installed in the middle position of the opening. By standing
A standard shutter device for disaster prevention with a width of 5 m or less was installed in a row.

Further, the disaster prevention shutter device has a disaster prevention section for securing an evacuation route for people in a building in an emergency such as a fire, that is, after the shutter curtain is lowered due to a fire or the like. In order to secure an escape route for those who are left behind, it is necessary to provide an emergency doorway.

Conventionally, in a disaster prevention shutter device equipped with a metal shutter curtain, it is relatively difficult to provide such an emergency entrance / exit in the shutter curtain itself, and therefore it is separate from the shutter device. To
There was often a sleeve door beside the emergency doorway.

On the other hand, in recent years, development of various materials has progressed, and a cloth screen excellent in fire resistance, heat shielding property, smoke shielding property, waterproof property, etc. has been developed, and a shutter curtain formed by such a cloth screen is developed. The provided disaster prevention shutter device has come to be used with the approval of the Minister of Construction under Article 38 of the Building Standards Act.

Since such a cloth screen can be sewn and the airtightness can be easily ensured, an emergency entrance / exit can be easily provided in the shutter curtain itself. A shutter device for disaster prevention in which an emergency doorway is provided on the shutter curtain itself formed of a screen has come to be used.

[0008]

However, when providing an emergency entrance / exit in the shutter curtain itself, it is not limited to the case of a shutter curtain formed of a cloth screen, but includes the case of a metal shutter curtain. There are various issues to consider, including:

That is, first of all, since the emergency entrance / exit is provided to secure an evacuation route, the emergency entrance / exit should be arranged in a disaster-prevention manner so that its original function can be fully exerted. Of the building near the opening where the shutter device should be installed (for example, walls and handrails,
Alternatively, it is desirable that the arrangement is made according to the arrangement situation of the escalator and the elevator. In other words, it is desired that the arrangement be made according to the behavioral characteristics (movement characteristics) of the evacuees during evacuation.

Next, in order to allow the evacuees to evacuate smoothly, as described above, the location of the emergency entrance / exit is determined according to the building conditions or the evacuee's behavioral characteristics. However, it is convenient and desirable for the evacuees to provide the shutter curtain with more emergency entrances and exits. However, if an unlimited number of emergency entrances and exits are provided in the shutter curtain, it becomes difficult to ensure airtightness, the smoke shielding performance may be deteriorated, the strength is not preferable, and further, it takes time and effort for manufacturing. This results in an increase in manufacturing cost. Therefore, it is necessary to provide an emergency entrance / exit at a position desired by the evacuee while avoiding the inconvenience from the viewpoint of manufacturing.

The above-mentioned problems regarding the arrangement of the emergency entrance / exit are that the larger the opening where the shutter device should be installed, that is, the wider the shutter curtain,
Since it becomes a remarkable problem, it is particularly closely related to the problem of dealing with large openings described below. Further, not only in the case of the shutter device for disaster prevention, but in the case of a shutter device having other purposes, the same problem occurs when the doorway is provided in the shutter curtain itself.

Further, there are spaces of various sizes in the building, and accordingly, the width of the opening in which the disaster prevention shutter device should be installed also varies. Therefore, when installing the disaster prevention shutter device, it is necessary to deal with a large opening, but in that case, there are the following problems.

That is, a disaster prevention shutter device having the above-mentioned metal shutter curtain and having a width of 5 m
If multiple standard specifications listed below are prepared and are connected in series to accommodate a large opening, the middle pillar with the guide rail must be set up at the middle position of the opening, which creates obstacles that form a large space. As a result, there are many restrictions on the architectural design, and the appearance is not preferable.

On the other hand, if the Minister of Construction approves it according to Article 38 of the Building Standards Act, even a disaster prevention shutter device having a metal shutter curtain with a width of more than 5 m can be used. It is conceivable to install one such wide disaster prevention shutter device to cope with a large opening.

However, in the case of a shutter curtain made of metal, increasing the width increases the weight and makes it difficult to handle during transportation, construction, or manufacturing. In particular, the width of the shutter curtain exceeds the standard specifications. That's the case with shutter curtains.

The problem of dealing with the large opening as described above is not limited to the disaster prevention shutter device, and even in the case of a shutter device having other purposes, when a space having a large cross section needs to be partitioned. It is a similar problem.

The main object of the present invention is to realize the arrangement of the door mechanism on the shutter curtain according to the situation of the building, which is convenient and convenient for those who want to use the door mechanism provided on the shutter curtain. There is a shutter device with a shutter.

[0018] An additional object of the present invention is to provide any one or more of facilitation of manufacturing, reduction of manufacturing cost, facilitation of handling during transportation and construction, and response to large opening. An object of the present invention is to provide a shutter device with a door mechanism that can be designed.

[0019]

SUMMARY OF THE INVENTION According to the present invention, a curtain main body for partitioning a space, a communicating portion for communicating the space between the front and back of the curtain partitioned by the curtain main body, and a door mechanism for covering the communicating portion and together with the communicating portion are provided. In a shutter device with a door mechanism including a shutter curtain having a covering portion, the door mechanism is arranged in the vicinity of a guiding unit that guides the movement of a moving body. That is, the door mechanism is arranged at a position where an extension line of the moving body guided by the guiding means in the moving direction of the moving body intersects with the shutter curtain, or a position in the vicinity thereof.

Structurally, the communicating portion has openings having various shapes such as a square, a rectangle, a triangle, a trapezoid, an M block cross section, an inverted home base shape, a circle, an ellipse, and a semicircle. Shaped or slit shaped are included. In terms of applications, emergency entrances and exits used for evacuation in the event of a fire or the like are the main ones, but in addition to this, people usually enter and exit and pass objects. Doors used, doors exclusively for pets such as dogs and cats, or mere viewing windows that do not assume the entry or exit of people or the passage of objects (for checking the situation behind the shutter curtain, for example, a shutter device for disaster prevention) In the case of, it is for checking the smoke generation status and fire progress status through the shutter curtain). In the present application, the term “entrance / exit” includes not only the case where bidirectional entrance / exit and passage are possible, but also the case where only entrance / exit in one direction is possible.

The cover portion may be formed as a separate member from the curtain body (for example, in the case of FIG. 1 described later), or may be integrally formed by the same member as the curtain body ( For example, in the case of FIG. 10 described later). When the cover is formed of a separate member like the former, the method of attaching the cover to the curtain body is, for example, sewing, adhesion, rivets, bolts / nuts, fastening with a fastener such as a screw, welding. , Fasteners, buttons, velcro connection, etc. are optional, and may be detachable or sliding door type that can be slid vertically, horizontally, etc. The attachment method may be selected depending on the purpose of installing the shutter device, such as whether the material of the shutter is required or whether airtightness needs to be secured. In addition, in either case such as the former case where it is formed of a separate member and the latter case where it is integrally formed, a structure may be adopted in which the cover can be prevented from opening by attaching a key.
Further, the surface of the cover portion may be provided with a mark or a character indicating the presence of the communication portion (for example, in the case of a disaster prevention shutter device, the presence of an emergency entrance / exit).

Further, when the door mechanism is focused on only one side of the front and back of the curtain, the most basic structure is that it is constituted by one communicating portion and one covering portion (for example, as will be described later). However, the present invention is not limited to this, and one door mechanism may be configured by a plurality of communication parts and one cover part (see, for example, FIG. 6 described later).
In the above case), one door mechanism may be configured by one communication part and a plurality of cover parts (for example, in the case of FIGS. 7 and 8 described later), and a plurality of communication parts and a plurality of communication parts. One door mechanism may be configured with the cover part (for example, in the case of FIG. 9 described later). In addition, when one door mechanism is composed of a plurality of cover portions among the above-mentioned patterns, the plurality of cover portions are combined and the whole or substantially the entire communication portion (however, the shutter device for disaster prevention is used. In the case of, it is preferable that the whole is completely covered.) It is sufficient that each cover covers the whole or substantially the entire communication part. Does not have to be. Therefore, when focusing on one cover portion, it is sufficient to cover at least a part of the communication portion (see FIGS. 7, 8, and 9 described later).

In constructing one door mechanism, the cover portion may be provided only on one side of the front and back of the shutter curtain or on both sides (for example, in the case of FIG. 2 described later). Further, it may be provided so as to enter the communication portion (for example, in the case of FIGS. 7 and 8 described later).

Further, the overlap portion of the cover portion and the curtain body may or may not be provided, but in the case of the shutter device for disaster prevention, it is easy to ensure airtightness. From the viewpoint, it is desirable to provide the overlap margin portion.

The moving body mainly means a person, but in addition to this, pets such as dogs and cats, vehicles such as forklifts and trucks, and objects such as products and merchandise sent on a conveyor line such as a belt conveyor. Are also included (for example,
(In the case of FIG. 13 described later). In the case of a shutter device for disaster prevention, it mainly means rescuers such as evacuees and firefighters who extinguish fires.

Further, the guide means is a wall, a walking aid member such as a handrail, a large number of continuous projections provided on the floor surface for the visually impaired or the like, or a laying sheet formed with these projections, and an entrance / exit of an elevator. , The upper and lower portions of the escalator, the upper and lower ends of stairs, and the conveyor line such as a belt conveyor. Then, as described above, a tactile guide means (a means that can physically limit the movement of the moving body) that allows the moving body to directly or indirectly contact and tactilely guide the movement of the moving body is provided. The main means,
In addition, visual guide means for visually guiding the movement of the moving body, for example, a guide light provided on a ceiling, a floor, a wall or the like, a guide display board, an entrance display board, and the like are also included. Further, an auditory guidance means for aurally guiding the movement of the moving body, for example, an alarm buzzer, a speaker, etc. are also included, and if the moving body has an excellent olfactory sense such as a dog, the olfactory moving body is olfactory. It also includes an olfactory guide means for inducing the movement of the. Also, a combination of these means may be used.

When a plurality of door mechanisms are arranged, it is sufficient that at least one door mechanism is arranged near the guiding means, and it is not necessary that all the door mechanisms are arranged near the guiding means. Absent. However, it is preferable that the majority (more preferably all) of the door mechanisms are arranged in the vicinity of the guiding means or in an end section described later.

In the present invention as described above, since the door mechanism is arranged in the vicinity of the guiding means for guiding the movement of the moving body,
The arrangement of the door mechanism according to the situation of the building, that is, the arrangement of the guiding means in the building is realized. Therefore, according to the movement characteristics of the moving body based on the guidance of the guiding means, for example, in the case of the disaster prevention shutter device, the arrangement according to the behavior characteristics of the evacuees during evacuation is realized, and the evacuation of the evacuees is smooth. The above-mentioned objects are achieved by these methods.

Further, according to the present invention, a curtain main body for partitioning a space, a communication portion for communicating the space on the front and back sides of the curtain partitioned by the curtain main body, and a cover portion for covering the communication portion and forming a door mechanism together with the communication portion. In a shutter device with a door mechanism including a shutter curtain having, N is an integer of 2 or more, and end positions on both sides of an inner width of the shutter curtain in a curtain width direction orthogonal to a moving direction of the shutter curtain. And a portion occupying the dimension width of 1 / N of the inner full width dimension in the curtain width direction from each inner width end position to the center position in the curtain width direction is defined as an end section. At this time, at least one door mechanism is arranged in at least one of these end sections.

Here, each meaning of the communication portion, the cover portion, and the door mechanism is the same as in the case of the invention in which the door mechanism is arranged in the vicinity of the guiding means described above.

Also, "moving direction of shutter curtain"
The term “open / close direction” when the shutter curtain performs the opening / closing operation (or the closing direction when only the closing operation is performed), and may be any of up / down direction, left / right direction, diagonal direction, horizontal direction, and the like. However, when using it as a shutter device for disaster prevention,
It is preferable to set the direction in which the weight can be lowered.

The "curtain width direction orthogonal to the moving direction of the shutter curtain" means the direction orthogonal to the moving direction of the shutter curtain in the plane along the shutter curtain, and the thickness direction of the shutter curtain (flesh direction). (Thickness direction) is not meant.

Further, the "internal full width dimension in the curtain width direction" refers to guide means (for example, guide rails or a groove formed directly on a wall or a pillar) in the full width dimension of the shutter curtain in the curtain width direction. The width dimension of the portion excluding the portion swallowed by, that is, the width dimension of the portion exposed to the outside (the portion visible from the space partitioned by the shutter curtain).

And, "at least one door mechanism is arranged in at least one of the end sections" means that
This means a state in which one whole door mechanism is entirely contained in the end compartment, and a case where only a part of one certain door mechanism is contained in the end compartment is excluded. Therefore, N = 2
The case means that there is at least one door mechanism that is not arranged across the central position in the curtain width direction. It should be noted that if one entire door mechanism fits within the end compartment, there may be other door mechanisms, only some of which are in the end compartment, or no door compartment at all. There may be other door mechanisms in disengaged positions.

"At least one of the end sections"
Therefore, the door mechanism does not necessarily have to be arranged in the end sections on both sides, and may be arranged only in one end section (for example, in the case of FIG. 4 described later). However, it is preferable that they are arranged in the end sections on both sides.

In the present invention as described above, since at least one door mechanism is arranged in at least one of the end sections on both sides, a guide rail or the like for guiding the shutter curtain is usually provided at the inner width end position. Since the wall for providing the guide means is arranged, the door mechanism can be arranged with the wall arrangement taken into consideration. Therefore, the door mechanism can be arranged according to the situation of the building, that is, the arrangement of the walls in the building. For example, in the case of a disaster prevention shutter device, it is expected to evacuate while moving along the wall. The arrangement according to the behavioral characteristics (movement characteristics) of the evacuees during evacuation is realized, and the evacuation of the evacuees can be performed smoothly, thereby achieving the above-mentioned object.

Further, in the invention in which the door mechanism is arranged in the end section described above, at least one door mechanism may be arranged near the guide means for guiding the movement of the moving body.

In this way, when the door mechanism is arranged both in the end section and in the vicinity of the guiding means, the arrangement of the door mechanism according to the situation of the building is further enhanced.

Further, in the invention in which the door mechanism is arranged in the end section described above, N is preferably an integer of 3 or more.

When N is an integer of 3 or more when defining the end sections in this way, between the end sections on both sides,
An intermediate section will be formed having a width dimension that is equal to or greater than the width dimension of the end section. Therefore, if the door mechanism is not arranged in this intermediate section, the door mechanism non-installed section can be secured in this intermediate section.

Therefore, in addition to realizing the arrangement of the door mechanism according to the situation of the building, that is, the arrangement of the walls in the building, by securing the section where the door mechanism is not installed, the reduction of the strength of the shutter curtain is prevented. , Reduce the labor of manufacturing,
It is possible to reduce the manufacturing cost and avoid inconveniences in manufacturing the shutter curtain. Further, in the case of the disaster prevention shutter device, it becomes easy to ensure the airtightness, and it is possible to prevent the smoke shielding performance from decreasing. That is,
In the case of a shutter device for disaster prevention, a request from an evacuee or a rescuer (hereinafter simply referred to as an evacuee) who wants smooth evacuation and a shutter that avoids manufacturing inconvenience It is possible to satisfy both the requirements of the curtain manufacturer, the builder, the owner, etc. (hereinafter sometimes simply referred to as the manufacturer).

In the invention for arranging the door mechanism in the end section described above, the inner width end position of the shutter curtain and the end on the inner width end position side of the door mechanism arranged in the end section. It is desirable that the distance from the portion is equal to or smaller than the width dimension of the door mechanism.

When the door mechanism is arranged in the end section as described above, the arrangement of the door mechanism according to the situation of the building, that is, the arrangement of the walls in the building becomes more effective.

Further, according to the present invention, a curtain main body for partitioning a space, a communication portion for communicating the front and back spaces of the curtain partitioned by the curtain main body, and a covering portion for covering the communication portion and forming a door mechanism together with the communication portion. In a shutter device with a door mechanism including a shutter curtain having, N is an integer of 2 or more, and end positions on both sides of an inner width of the shutter curtain in a curtain width direction orthogonal to a moving direction of the shutter curtain. And a portion occupying the dimension width of 1 / N of the inner full width dimension in the curtain width direction from each inner width end position to the center position in the curtain width direction is defined as an end section. At this time, the door mechanism is arranged only in each end section of the shutter curtain or in the vicinity of the guiding means for guiding the movement of the moving body, and is not arranged in other portions. Not that is characterized in.

As described above, the door mechanism should not be arranged in a portion other than "in each end section or in the vicinity of the guiding means", that is, in a portion which is neither in each end section nor in the vicinity of the guiding means. In such a case, the door mechanism is arranged only at a position necessary for a person who intends to use the door mechanism provided on the shutter curtain, and the door mechanism is not arranged at a position where the necessity is not so high.

Therefore, in addition to realizing the arrangement of the door mechanism according to the situation of the building, that is, the arrangement of the walls or the arrangement of the guiding means in the building, the door mechanism is not arranged in other parts. Therefore, it is possible to avoid disposing the door mechanism at a position where the necessity is not so high. Therefore, it is possible to prevent the strength of the shutter curtain from decreasing, reduce the manufacturing labor, reduce the manufacturing cost, and avoid the disadvantages in manufacturing the shutter curtain. Further, in the case of the disaster prevention shutter device, it becomes easy to ensure the airtightness, and it is possible to prevent the smoke shielding performance from decreasing. In other words, in the case of the shutter device for disaster prevention, the request of the evacuees that they want to be able to evacuate smoothly,
It becomes possible to satisfy the demand of the shutter curtain manufacturer who wants to avoid manufacturing inconvenience.

In the above, the purpose of installing the shutter device with the door mechanism of the present invention (including the invention of arranging the door mechanism in the vicinity of the guiding means and the invention of arranging the door mechanism in the end section) is arbitrary. There is, for example, a shutter device for disaster prevention mainly for fire prevention and smoke prevention, but it is not limited to this, and it forms a special space such as a dark room, a clean room, a cold storage, a greenhouse. The shutter device may be a shutter device for solar radiation, a shutter device for shielding sunlight, a shutter device for crime prevention, etc.
Any shutter device in which it is useful to provide a door mechanism on the shutter curtain may be used.

Further, the shutter device with the door mechanism of the present invention (including the invention of arranging the door mechanism in the vicinity of the guiding means and the invention of arranging the door mechanism in the end section) is optional. , For example, ordinary houses, buildings,
Provided in various buildings such as shutter devices for entrances and exits of garages, factories, warehouses, cold storages, etc., shutter devices for windows, shutter devices provided in the middle of aisles in buildings and at the boundary between aisles and halls, etc. It may be a shutter device, or may be a shutter device provided in various structures such as an underground mall, a station yard, a tunnel, and a ship.

Further, the structure of the shutter device with the door mechanism of the present invention (including the invention of arranging the door mechanism in the vicinity of the guiding means and the invention of arranging the door mechanism in the end section) is a shutter curtain. It is optional as long as the door mechanism can be provided. Therefore, the present invention can be applied to various types of shutter devices as follows. For example, the shutter curtain may be formed by using a sheet-shaped member, and the shutter curtain may be wound around a winding shaft or folded and stored in a storage unit. It may be a shutter device of a type that is formed by connecting the shutter curtains, and the shutter curtain is wound around the winding shaft of the storage unit and stored. Also, a shutter curtain is formed by arranging a plurality of panels in series,
The shutter curtain may be of a type in which the individual panels of the shutter curtain are separated and overlapped and stored in the storage section, or the individual panels are folded and stored in a connected state, and are further wound and stored. . Further, the shutter curtain may be a shutter device formed by a plurality of pipe members connected to each other by a link member, or may be an overhead type shutter device for feeding and storing. In addition, for example, a shutter device having a shutter curtain formed by combining various shutter curtains, such as a shutter curtain in which a part is formed of slats and the remaining part is formed of a sheet-like member. But it's okay. The materials for the components and members of the various shutter curtains described above are arbitrary, and examples of the sheet-shaped member include a cloth screen, a soft resin sheet such as vinyl chloride or urethane, and rubber. Alternatively, a sheet or the like formed of a rubber-like substance can be used, and if it is a slat, a panel, a link member, a pipe member, or the like, for example, metal, synthetic resin, ceramics, wood or the like can be used.

Further, as described above, the material of the constituent parts and constituent members of the shutter curtain is arbitrary, but the following is particularly preferable. That is, in the above-mentioned invention (including both the invention of arranging the door mechanism in the vicinity of the guiding means and the invention of arranging the door mechanism in the end section), the cover portion overlaps with at least the cover portion of the curtain body. It is preferable that both the overlap margin portion be formed of a sheet-shaped member.

Here, the sheet-like member is a cloth screen, a vinyl sheet, a urethane sheet, a rubber sheet, or the like.
Any kind of flexible material may be used,
When using for disaster prevention purposes such as fire prevention and smoke prevention, for example,
Silica cloth or glass cloth, or those obtained by spraying, coating or impregnating them with a fireproof coating material or a waterproof coating material as a fireproof coating material can be suitably used. Further, the sheet-shaped member may be combined with a metal for reinforcement such as a wire mesh or a resin wire rod, and if such a reinforcement is performed, not only when used for disaster prevention purposes but also for normal use. Even in this case, the sheet is less likely to be damaged, and the durability of the sheet can be improved, which is effective.

The present invention can be preferably applied to a shutter curtain formed by including a sheet-like member as described above, because a sheet-like member such as a cloth screen is lighter than a metal shutter curtain. Since it can be folded, it can be easily handled during transportation, construction, or manufacturing. Therefore, the shutter curtain formed by including the sheet-shaped member,
It is suitable for a wide shutter curtain, and the larger the width of the curtain, the greater its advantage.
Also, since it is a sheet-shaped member, it is possible to sew,
Compared to a metal shutter curtain, it is structurally suitable for providing a door mechanism, and it is easier to ensure airtightness than a metal shutter curtain. Therefore, the shutter curtain formed by including the sheet-shaped member is most suitable for constructing a disaster prevention shutter device corresponding to a large opening.

The sheet-like member forming the series of shutter curtains may be a single sheet, or a plurality of sheets may be joined by sewing, bonding, welding, or the like. It may be a divided type divided into a plurality in the width direction, and may be combined with a fastener or the like at the time of closing operation of the shutter curtain, or may be simply overlapped without being combined to form a series of shutter curtains.

As described above, the purpose of installing the shutter device with the door mechanism of the present invention is arbitrary, but the following is particularly preferable. That is, in the above-described invention (including both the invention of arranging the door mechanism in the vicinity of the guiding means and the invention of arranging the door mechanism in the end section), the shutter curtain has a disaster prevention function, and the communication portion is extremely It is preferable that it is a doorway.

Here, the disaster prevention function exhibits at least one kind of performance among various performances such as fireproof performance, fireproof performance, smokeproof performance, smoke shield performance, heat shield performance, waterproof performance and wind pressure resistance performance. What you can do.

As described above, the present invention can be suitably applied to the disaster prevention shutter device in the disaster prevention shutter device.
This is because it is originally required to provide an emergency entrance / exit for securing an evacuation route for evacuees, so that the effect of the present invention regarding the arrangement of the door mechanism can be sufficiently exerted.

Further, in the above, the inner dimension in the width direction of the shutter curtain in the shutter device with the door mechanism of the present invention is arbitrary, but the following is particularly preferable. That is, in the above-mentioned invention (including both the invention of arranging the door mechanism in the vicinity of the guiding means and the invention of arranging the door mechanism in the end section), the shutter curtain has a standard inner method in the curtain width direction. It is preferable that the shutter curtain for large openings has an inner dimension larger than the dimension and partitions a space having a large cross-sectional width.

The fifth condition is that the inner full width dimension in the curtain width direction is about 3 times or more, preferably about 6 times or more the width dimension of the door mechanism. Here, the standard value of about 3 times is obtained when one door mechanism is provided at each inner end of the shutter curtain and a door mechanism non-installation portion having a dimension width similar to these is secured between them. It is based on the fact that it can be regarded as a large opening shutter curtain when it is more than such a value. In addition, the standard value of about 6 times is that one door mechanism is provided from both inner ends of the shutter curtain with a distance corresponding to the width dimension of the door mechanism, and between these, a dimension width (door It is a value obtained when a door mechanism non-installation part having a width dimension of two parts) is secured, and when it exceeds this value, it can be regarded as a large opening shutter curtain.

As described above, the present invention can be preferably applied to the shutter curtain for large openings, as the width of the shutter curtain becomes larger, the arrangement of the door mechanism is realized according to the situation of the building, and the door mechanism is used. This is because there is a high demand for the realization of a shutter device that is convenient and convenient for those who are trying to use it.Moreover, the larger the width of the shutter curtain, the heavier the weight becomes. This is because it becomes difficult to handle, and it is highly necessary to facilitate handling by the present invention.

Among the shutter devices with the door mechanism described above, one of the most suitable constitutional examples for the present invention is the one having the following constitution. That is, the invention described above (the invention of arranging the door mechanism in the vicinity of the guiding means,
And any invention that places a door mechanism in the end compartment. ), The cover portion and the overlap margin portion of the curtain body overlapping at least the cover portion are both formed of a sheet-like member, and the shutter curtain has an inner dimension of more than 12 m in the curtain width direction, and A large opening shutter curtain that partitions a space having a large cross-sectional width can be used.

Further, in the above, the structure of the communicating portion in the shutter device with the door mechanism of the present invention may be open or slit as described above, but the following is particularly preferable. That is, in the above-described invention (including both the invention of arranging the door mechanism in the vicinity of the guiding means and the invention of arranging the door mechanism in the end section), the communication part has an opening shape having a two-dimensional spread. It is preferable that the shutter curtain has a side having a constant width and disposed in the vicinity of the closing direction front end portion of the shutter curtain, the side having a constant width.

Here, the front end portion of the shutter curtain in the closing direction refers to a portion provided with, for example, a seat plate and a weight. Also, "aperture with a two-dimensional spread" means
The purpose of excluding the slit shape is that "having a side with a constant width" means excluding a shape such as an inverted triangle or a circle that does not have a side along the front end in the closing direction. Therefore,
The shapes include squares, rectangles, triangles (bases of which extend along the closing direction front end), trapezoids, M block cross-sections, inverted home bases, semicircles (upper half of circle), and the like.

In the case of such a structure, since the communication portion has an opening shape, it becomes possible to easily pass through the communication portion as compared with the case of the slit shape. Therefore, for example, in the case of a shutter device for disaster prevention, evacuation can be performed smoothly.
