TECHNICAL 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, for a disaster prevention shutter device for performing fire prevention, smoke prevention, and the like. It can be suitably used as a large aperture shutter device for partitioning.
[0002]
[Background Art]
Generally, shutters for various purposes are provided at the entrance and exit of a building or in the middle of a passage so as to partition a space by moving a shutter curtain up and down, and a disaster prevention shutter device for performing fire prevention, smoke prevention, etc. Is one of them.
[0003]
Conventionally, as such a disaster prevention shutter device, a device provided with a metal (iron) shutter curtain has been used. The disaster prevention shutter device equipped with a metal shutter curtain has a width based on the Ministry of Construction notification (Notification 2564, 1972) based on Article 112, paragraph 14, item 4 of the Building Standards Law Enforcement Order. Is 5 m or less as a standard specification. Therefore, in the case of a so-called large opening where the opening in the building where the disaster prevention shutter device is to be installed (the cross-sectional width of the space to be partitioned by the shutter curtain) is large, a guide rail is usually provided at an intermediate position between the openings. By setting up a pillar, a standard disaster prevention shutter device with a width of 5 m or less was provided in series to respond.
[0004]
In addition, the disaster prevention shutter device should be left behind in the disaster prevention compartment after the shutter curtain is lowered due to a fire, etc., to secure an evacuation route for people in the building in the event of an emergency such as a fire. Emergency entrances and exits will need to be provided to ensure that escaped people can escape.
[0005]
Conventionally, in a disaster prevention shutter device having a metal shutter curtain, it is relatively difficult to provide such an emergency doorway in the shutter curtain itself. In many cases, side doors for emergency doorways were provided.
[0006]
On the other hand, in recent years, development of various materials has progressed, and cloth screens having excellent fire resistance, heat shielding properties, smoke shielding properties, waterproofness, etc. have been developed, and disaster prevention with a shutter curtain formed by such cloth screens has been developed. Shutter devices have been used with the approval of the Minister of Construction under Article 38 of the Building Standards Act.
[0007]
Such a cloth screen can be sewn, and since it is easy to secure airtightness, an emergency doorway can be easily provided in the shutter curtain itself. Disaster prevention shutter devices have been used in which an emergency entrance is provided in the shutter curtain itself.
[0008]
[Problems to be solved by the invention]
However, when providing an emergency doorway in the shutter curtain itself, not only the case of the shutter curtain formed by a cloth screen but also the following various considerations including the case of a metal shutter curtain. There is a problem.
[0009]
That is, first, the emergency doorway is provided to secure an evacuation route, so that the emergency doorway is arranged so that its essential functions can be sufficiently exhibited. It is desired that the arrangement be in accordance with the state of the building (for example, the arrangement state of walls, handrails, escalators, elevators, etc.) in the vicinity of the opening in which is to be provided. In other words, it is desired that the evacuees be arranged in accordance with the behavior characteristics (movement characteristics) at the time of evacuation.
[0010]
Next, in order to ensure that the evacuees are evacuated smoothly, the emergency entrance and exit locations should be set according to the situation of the building or the behavioral characteristics of the evacuees caused by the situation as described above. However, for evacuees, it can be said that it is convenient and desirable in terms of evacuation for the shutter curtain to have more emergency doorways. However, providing an emergency doorway to the shutter curtain indefinitely makes it difficult to ensure airtightness, which may reduce smoke-blocking performance, is not desirable in terms of strength, and requires more labor for manufacturing. As a result, the manufacturing cost is increased. Therefore, it is necessary to provide an emergency entrance at a position desired for evacuees while avoiding these disadvantages from a manufacturing viewpoint.
[0011]
The above-mentioned problems relating to the layout of the emergency doorway become more serious as the opening for installing the shutter device becomes larger, that is, as the width of the shutter curtain becomes wider. There is a deep relationship with the response to the problem. In addition, not only the shutter device for disaster prevention but also a shutter device having another purpose is a problem that similarly occurs when an entrance or the like is provided in the shutter curtain itself.
[0012]
In addition, there are various sizes of the space in the building, and accordingly, the width of the opening where the disaster prevention shutter device is to be installed is also various in size. Therefore, when installing the disaster prevention shutter device, it is necessary to cope with a large opening, but at that time, there are the following problems.
[0013]
That is, a plurality of disaster prevention shutter devices having the above-mentioned metal shutter curtain and having a standard width of 5 m or less are prepared, and a guide rail is provided in order to connect them in order to cope with a large opening. Since the center pillar must be set up at an intermediate position of the opening, there are many restrictions on architectural design, such as an obstacle to forming a large space, and there is a problem that the appearance is unfavorable.
[0014]
On the other hand, when approved by the Minister of Construction in accordance with Article 38 of the Building Standards Act, even a disaster prevention shutter device having a metal shutter curtain having a width exceeding 5 m can be used. It is also conceivable to install one wide disaster prevention shutter device to handle large openings.
[0015]
However, in the case of a metal shutter curtain, increasing the width increases the weight, making it difficult to handle during transportation, construction, or manufacturing, especially in a shutter curtain having a width exceeding the standard specification. , It is remarkable.
[0016]
The problem of dealing with a large opening as described above is not limited to the shutter device for disaster prevention, but also occurs in the case of a shutter device having another purpose when a space having a large sectional width must be partitioned. It is a problem.
[0017]
A main object of the present invention is to provide a shutter device with a door mechanism that can realize the arrangement of a door mechanism on a shutter curtain according to the situation of a building and is convenient and convenient for those who intend to use the door mechanism provided on the shutter curtain. To provide
[0018]
Further, an additional object of the present invention is to appropriately implement one or more of simplification of manufacturing, reduction of manufacturing cost, simplification of handling during transportation and construction, and correspondence to large openings. The present invention is to provide a shutter device with a door mechanism that can be used.
[0019]
[Means for Solving the Problems]
The present invention provides a shutter curtain having a curtain body for partitioning a space, a communicating portion communicating the spaces on the front and back of the curtain partitioned by the curtain body, and a covering portion covering the communicating portion and forming a door mechanism together with the communicating portion. In the shutter device with the door mechanism provided with the above, the door mechanism is arranged near the guiding means for guiding the movement of the moving body. That is, the door mechanism is characterized in that it is disposed at a position where an extension of the moving direction of the moving body guided by the guiding means intersects with the shutter curtain, or at a position near the intersection.
[0020]
Here, in terms of structure, the communicating portion has an opening shape having various shapes such as a square, a rectangle, a triangle, a trapezoid, an M block sectional shape, an inverted home base shape, a circle, an ellipse, and a semicircle. , Or a slit shape. In terms of applications, emergency doorways used for emergency evacuation in the event of a fire, etc. are mainly mentioned, but in addition to this, it is usually used for entering and exiting people and passing objects. Doorways used, doors dedicated to pets such as dogs and cats, or mere viewing windows that do not assume the entrance 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 (1), it is used to check the state of smoke generation and the progress of fire through the shutter curtain). Note that the term “entrance / exit” in the present application includes not only a case where entry and exit can be performed in both directions but also a case where entry and exit can be performed only in one direction.
[0021]
In addition, the covering portion may be formed of a separate member from the curtain body (for example, in the case of FIG. 1 described below) or may be formed integrally with the same member as the curtain body (for example, described later). Of FIG. 10). In the case where the cover is formed by a separate member as in the former, the method of attaching the covering portion to the curtain body includes, for example, fastening, welding, fastening with a fastening tool such as rivets, bolts and nuts, and screws. , Fastening using fasteners, buttons, or Velcro, etc. are optional.Furthermore, it may be a detachable mounting, or a sliding door type that can slide up, down, left and right, etc. In short, a cover or curtain The mounting method may be determined according to the material of the main body or the installation purpose of the shutter device such as whether or not it is necessary to secure airtightness. Note that, in any of the case where the cover is formed of a separate member as in the former case and the case where the cover is formed integrally as in the case of the latter, a configuration may be employed in which a key is attached to prevent the cover from opening. Further, a mark or a character indicating the existence of the communication part (for example, in the case of a disaster prevention shutter device, the presence of an emergency entrance) may be provided on the surface of the cover part.
[0022]
Further, when focusing on only one side of the front and back of the curtain, the door mechanism has the most basic structure including one communication portion and one cover portion (for example, FIG. However, the present invention is not limited to this, and one door mechanism may be configured by a plurality of communicating portions and one covering portion (for example, in the case of FIG. 6 described later). One door mechanism may be configured by one communication portion and a plurality of cover portions (for example, in the case of FIGS. 7 and 8 described below), and one door mechanism is configured by the plurality of communication portions and the plurality of cover portions. One door mechanism may be configured (for example, in the case of FIG. 9 described later). In the case where one door mechanism is constituted by a plurality of covering portions in each of the above patterns, the plurality of covering 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 entirety be completely covered.) It is sufficient that the entirety is covered, and each covering part necessarily covers the entirety or substantially the entirety of the communication part. It doesn't have to be. Therefore, when focusing on one covering portion, it is sufficient that at least a part of the communication portion is covered (see FIGS. 7, 8, and 9 described later).
[0023]
In configuring one door mechanism, the cover portion may be provided on only one side of the front and back sides of the shutter curtain, may be provided on both sides (for example, in the case of FIG. 2 described below), and further, May be provided so as to enter into the communication portion (for example, in the case of FIGS. 7 and 8 described later).
[0024]
Furthermore, the overlap portion between the covering portion and the curtain body may be provided or may not be provided, but in the case of a disaster prevention shutter device, from the viewpoint of easily ensuring airtightness, It is desirable to provide an overlap margin portion.
[0025]
In addition, the moving body mainly means a person, but also includes objects such as pets such as dogs and cats, vehicles such as forklifts and trucks, products and goods which can be sent on a conveyor line such as a belt conveyor, and the like. (For example, in the case of FIG. 13 described later). In the case of a disaster prevention shutter device, it mainly means a rescuer such as an evacuee or a firefighter who extinguishes a fire.
[0026]
Further, the guide means include a wall, a walking assist member such as a handrail, a large number of continuous projections provided on a floor surface for a visually impaired person or the like, a laying sheet formed with these projections, an entrance to an elevator, an escalator, and the like. Includes the upper and lower entry and exit portions, the upper and lower ends of stairs, and conveyor lines such as belt conveyors. Tactile guidance means (means that can physically restrict the movement of the moving body) that can directly or indirectly contact the moving body and thus tactilely guide the movement of the moving body are provided. Although it is a main means, in addition to this, a visual guidance means for visually guiding the movement of the moving body, for example, a guide light, a guide display board, an entrance display board, etc. provided on a ceiling, a floor, a wall, and the like are also included. . In addition, an auditory guidance means for acoustically inducing the movement of the moving object, for example, an alarm buzzer or a speaker is also included. Olfactory inducing means for inducing the movement of the body. Further, a combination of these means may be used.
[0027]
When a plurality of door mechanisms are arranged, it is sufficient that at least one door mechanism is arranged near the guide means, and it is not necessary that all door mechanisms are arranged near the guide means. However, it is preferable that the majority (more preferably all) of the door mechanisms are arranged in the vicinity of the guide means or in an end section described later.
[0028]
In the present invention, since the door mechanism is arranged near the guidance means for guiding the movement of the moving body, the arrangement of the door mechanism according to the state of the building, that is, the arrangement state of the guidance means in the building is realized. You. For this reason, an arrangement according to the movement characteristics of the moving body based on the guidance of the guidance means, for example, in the case of a disaster prevention shutter device, is realized according to the behavior characteristics at the time of evacuation of the evacuees, and the evacuation of the evacuees is smooth. The purpose is achieved by these.
[0029]
Further, the present invention has a curtain body that partitions a space, a communication portion that communicates the space on the front and back of the curtain partitioned by the curtain body, and a covering portion that covers the communication portion and forms a door mechanism together with the communication portion. In a shutter device with a door mechanism having a shutter curtain, N is an integer of 2 or more, and among the shutter curtains, includes both end positions on an inner width in a curtain width direction orthogonal to a moving direction of the shutter curtain, When a portion occupying one-Nth of the width of the inner width in the curtain width direction from the end position of each inner width toward the center position in the curtain width direction is defined as an end section, , At least one of the end sections is provided with at least one door mechanism.
[0030]
Here, the respective meanings of the communication part, the cover part, and the door mechanism are the same as in the case of the invention in which the door mechanism is arranged near the above-described guidance means.
[0031]
The “moving direction of the shutter curtain” refers to the opening / closing direction when the shutter curtain performs the opening / closing operation (in the case of performing only the closing operation, the closing direction), and includes a vertical direction, a horizontal direction, an oblique direction, It is arbitrary such as a horizontal direction. However, in the case of a disaster-prevention shutter device, it is preferable to set the direction so that it can descend by its own weight.
[0032]
Further, the “curtain width direction perpendicular to the direction in which the shutter curtain moves” refers to a direction perpendicular to the direction in which the shutter curtain moves in a plane along the shutter curtain, and the thickness direction (thickness direction) of the shutter curtain. It does not mean.
[0033]
Further, the “inner width dimension in the curtain width direction” is swallowed by guide means (for example, a guide rail or a groove directly formed on a wall or a pillar) out of the full width dimension in the curtain width direction of the shutter curtain. The width of the part excluding the part, that is, the width of the part exposed to the outside (the part seen from the space partitioned by the shutter curtain).
[0034]
And, "at least one of the end sections has at least one door mechanism disposed" means a state in which the entirety of a certain door mechanism is housed in the end section, and a certain one If only a part of the door mechanism is in the end section, it is excluded. Therefore, the case where N = 2 means that there is at least one door mechanism that is not arranged across the center position in the curtain width direction. If the entirety of one door mechanism fits in the end section, there may be another door mechanism in which only a part is in the end section, or the door section may be completely removed from the end section. There may be other door mechanisms in the off position.
[0035]
Further, since it is “at least one of the end sections”, the door mechanism does not necessarily need to be arranged in both end sections, and may be arranged only in one end section (for example, as described later). Of FIG. 4). However, it is preferable to be arranged in both end sections.
[0036]
In the present invention, since at least one door mechanism is arranged on at least one of the end sections on both sides, usually, a guide means such as a guide rail for guiding the shutter curtain is provided at the inner width end position. Since the wall for providing the door is arranged, the door mechanism can be arranged in consideration of the arrangement of the wall. For this reason, the arrangement of the door mechanism according to the state of the building, that is, the arrangement of the walls in the building is realized. For example, in the case of a disaster prevention shutter device, it is expected that the evacuation will be performed while moving along the wall. The arrangement according to the behavior characteristics (movement characteristics) at the time of evacuation of the evacuees is realized, and the evacuees can be evacuated smoothly, thereby achieving the above object.
[0037]
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 guiding means for guiding the movement of the moving body.
[0038]
When the door mechanisms are arranged both in the vicinity of the end section and in the vicinity of the guiding means, the arrangement of the door mechanisms according to the situation of the building is further enhanced.
[0039]
Further, in the invention in which the door mechanism is disposed in the above-described end section, it is preferable that N is an integer of 3 or more.
[0040]
When N in defining the end sections is an integer of 3 or more, the width between the end sections on both sides is equal to or larger than the width of the end sections. An intermediate section will be formed. Therefore, if the door mechanism is not arranged in this intermediate section, it is possible to secure a section in which the door mechanism is not installed in this intermediate section.
[0041]
For this reason, in addition to realizing the arrangement of the door mechanism according to the situation of the building, that is, the arrangement state of the wall in the building, the securing of the section where the door mechanism is not installed prevents the strength of the shutter curtain from being reduced, and the production of the shutter curtain is prevented. It is possible to reduce the labor, reduce the manufacturing cost, and avoid inconvenience in manufacturing the shutter curtain. In the case of a disaster prevention shutter device, it is easy to secure airtightness, and it is possible to prevent a decrease in smoke blocking performance. In other words, in the case of a disaster prevention shutter device, it is necessary to avoid the demands of evacuees or rescuers (hereinafter, sometimes simply referred to as evacuees) who want smooth evacuation and inconvenience in manufacturing. And the requirements of the shutter curtain manufacturer or the installer or the owner (hereinafter, may be simply referred to as the manufacturer).
[0042]
And in the invention in which the door mechanism is arranged in the end section described above, the inner width end position of the shutter curtain and the inner width end position side end of the door mechanism arranged in the end section are described. It is desirable that the interval be equal to or smaller than the width of the door mechanism.
[0043]
When the door mechanism in the end section is arranged in this way, the arrangement of the door mechanism according to the situation of the building, that is, the arrangement state of the wall in the building, becomes more effective.
[0044]
Further, the present invention has a curtain body that partitions a space, a communication portion that communicates the space on the front and back of the curtain partitioned by the curtain body, and a covering portion that covers the communication portion and forms a door mechanism together with the communication portion. In a shutter device with a door mechanism having a shutter curtain, N is an integer of 2 or more, and among the shutter curtains, includes both end positions on an inner width in a curtain width direction orthogonal to a moving direction of the shutter curtain, When a portion occupying 1 / N of the width of the inner width in the curtain width direction from the end position of each inner width toward the center position in the curtain width direction is defined as an end section, The mechanism should be located 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 not in other parts. The one in which the features.
[0045]
As described above, when the door mechanism is not arranged in a portion other than “in each end section or in the vicinity of the guiding means”, that is, not in each end section and in a portion that is not near the guiding means. The door mechanism is disposed 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 disposed at a position where the need is not so high.
[0046]
For this reason, in addition to realizing the arrangement of the door mechanism according to the situation of the building, that is, the arrangement state of the wall or the arrangement state of the guiding means in the building, the door mechanism is not arranged in other parts, so that It is possible to avoid disposing the door mechanism at a position where the necessity is not high. Therefore, it is possible to prevent a decrease in the strength of the shutter curtain, reduce the labor for manufacturing, reduce the manufacturing cost, and avoid inconvenience in manufacturing the shutter curtain. In the case of a disaster prevention shutter device, it is easy to secure airtightness, and it is possible to prevent a decrease in smoke blocking performance. In other words, in the case of the disaster prevention shutter device, both the evacuee's request for smooth evacuation and the shutter curtain manufacturer's request for avoiding manufacturing inconvenience can be satisfied. Become like
[0047]
In the above, the installation purpose of the shutter device with the door mechanism of the present invention (including both the invention in which the door mechanism is arranged near the guiding means and the invention in which the door mechanism is arranged in the end section) is arbitrary. The main one is a disaster prevention shutter device for the purpose of fire prevention, smoke prevention, etc., but is not limited thereto, and is used for forming a special space such as a dark room, a clean room, a cold storage room, a heat insulation room, and the like. It may be a shutter device, a shutter device for shielding sunlight, a shutter device for crime prevention, or the like. In short, any shutter device that is useful for providing a shutter mechanism with a door mechanism may be used.
[0048]
Furthermore, the installation location of the shutter device with the door mechanism of the present invention (including both the invention in which the door mechanism is arranged near the guiding means and the invention in which the door mechanism is arranged in the end section) is arbitrary, for example, Such as shutter devices for various entrances and exits of ordinary general houses, buildings, garages, factories, warehouses, cold storages, etc., shutter devices for windows, shutter devices provided in the middle of the passage in the building or at the boundary between the passage and the hall, etc. It may be a shutter device provided in various buildings, or may be a shutter device provided in various structures such as an underground mall, a station premises, a tunnel, a ship, and the like.
[0049]
In addition, the structure of the shutter device with the door mechanism of the present invention (including both the invention in which the door mechanism is disposed near the guiding means and the invention in which the door mechanism is disposed in the end section) includes the door mechanism in the shutter curtain. It is optional as long as it can be provided. Therefore, the present invention can be applied to the following various types of shutter devices. For example, a shutter device in which a shutter curtain is formed using a sheet-shaped member, and this shutter curtain is wound around a winding shaft or folded and stored in a storage unit may be used. The shutter device may be formed by connecting the shutter curtains, and the shutter curtain may be wound around a winding shaft of a storage unit and stored. Further, the shutter curtain is formed by connecting a plurality of panels, and the individual panels of the shutter curtain are separated and stacked and stored in the storage unit, or the individual panels are folded and stored in the connected state. The shutter device may be of a type that is wound up and stored. Further, the shutter device may be a shutter device in which the shutter curtain is formed of 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. Further, for example, a shutter device of a type including a shutter curtain formed by combining various types of shutter curtains, such as a shutter curtain partially formed of slats and the remaining portion formed of a sheet-shaped member. May be. The materials of the components and components of the various shutter curtains described above are arbitrary. If the material is a sheet-like member, for example, a screen made of cloth, or a soft resin sheet such as vinyl chloride or urethane, or even rubber Alternatively, a sheet or the like formed of a rubber-like substance can be used, and a metal, a synthetic resin, ceramics, wood, or the like can be used as long as it is a slat, panel, link member, pipe member, or the like.
[0050]
Further, as described above, the materials of the components and members of the shutter curtain are arbitrary, but the following is particularly preferable. That is, in the above-described inventions (including both the invention in which the door mechanism is arranged near the guiding means and the invention in which the door mechanism is arranged in the end section), the cover portion overlaps at least the cover portion of the curtain body. It is preferable that both the overlap margin portions are formed by sheet-like members.
[0051]
Here, the sheet-like member may be of any type as long as it is flexible, such as a cloth screen, a vinyl sheet, a urethane sheet, a rubber sheet, etc., but is used for disaster prevention purposes such as fire prevention and smoke prevention. In this case, for example, silica cloth or glass cloth, or a material obtained by spraying, applying, or impregnating a fire-resistant paint or a waterproof coating material as a fire-resistant coating material on these materials can be suitably used. Further, the sheet-shaped member may be combined with a reinforcing metal such as a wire mesh or a resin wire, or the like. Even in this case, the sheet is less likely to be damaged, and the durability of the sheet can be improved, which is effective.
[0052]
The present invention can be suitably applied to the shutter curtain formed including the sheet-like member as described above, because a sheet-like member such as a cloth screen is lighter than a metal shutter curtain and can be folded. Because it is possible, handling during transportation, construction, or manufacturing becomes easy. For this reason, the shutter curtain formed including the sheet-like member is suitable for a wide shutter curtain, and the advantage increases as the width of the curtain increases. In addition, since it is a sheet-shaped member, it can be sewn, etc., and is more suitable for providing a door mechanism structurally than a metal shutter curtain, and also has a higher airtightness than a metal shutter curtain. Easy. Therefore, the shutter curtain formed including the sheet-like member is most suitable for configuring a disaster prevention shutter device corresponding to a large opening.
[0053]
In addition, the sheet-shaped member which forms a series of shutter curtains may be a single sheet, or a plurality of sheets joined by sewing, bonding, welding, or the like. The shutter curtain may be divided into a plurality of types, and may be combined with a fastener or the like at the time of closing the shutter curtain or may be simply overlapped without being combined to form a series of shutter curtains.
[0054]
Further, as described above, the purpose of installing the shutter device with a door mechanism of the present invention is arbitrary, but it is particularly preferable to perform the following. That is, in the above-mentioned inventions (including both the invention in which the door mechanism is arranged near the guiding means and the invention in which the door mechanism is arranged in the end section), the shutter curtain has a disaster prevention function, and the communication part is an emergency. It is preferably an entrance for use.
[0055]
Here, the disaster prevention function means that it can exhibit at least one kind of performance among various performances such as fire prevention performance, fire resistance performance, smoke prevention performance, smoke blocking performance, heat blocking performance, waterproofing performance, wind resistance performance, and the like. .
[0056]
The reason why the present invention can be suitably applied to the disaster prevention shutter device is that the disaster prevention shutter device is originally required to provide an emergency doorway for securing an evacuation route for evacuees, This is because the effect of the present invention regarding the arrangement of the door mechanism is sufficiently exhibited.
[0057]
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-described inventions (including both the invention in which the door mechanism is arranged near the guiding means and the invention in which the door mechanism is arranged in the end section), the shutter curtain uses the standard inner method in the curtain width direction. It is preferable that the shutter curtain be a large opening shutter curtain having an inner dimension larger than the dimension and partitioning a space having a large sectional width.
[0058]
Here, the shutter shutter for a large opening means one that satisfies at least one of the following conditions.
[0059]
The first condition is that the width exceeds the width based on the notification of the Ministry of Construction based on Article 112, paragraph 14, item 4 of the Building Standards Law Enforcement Order (Notification 2564 of 1973), that is, One that exceeds 5 m (larger than the standard specification of so-called iron fire and smoke shutters).
[0060]
The second condition is that the width exceeds the width based on the “Ministry of Construction Notification based on Article 112, Paragraph 14, Item 4 of the Building Standards Law Enforcement Order (Notification 2564, 1973)”, It is more than 8 m (larger than the iron shutter attached to the position close to the type B fire door).
[0061]
The third condition is that vehicles (cargoes loaded) specified by a Cabinet Order based on Article 47, Paragraph 1 of the Road Law (Vehicle Restriction Order, Article 3, Paragraph 1, Item 4; Cabinet Order 375, last amended 1993) In this case, the length of the curtain in that state exceeds the maximum limit, that is, the total width in the curtain width direction exceeds 12 m.
[0062]
The fourth condition is that a semi-trailer-connected vehicle that travels on a national highway specified by a Cabinet Order based on Article 47, Paragraph 1 of the Road Law (Act. Full trailer-coupled vehicles whose loaded cargo does not protrude forward or backward of the body of the towing vehicle, exceeding the maximum length, that is, the full width dimension in the curtain width direction is 16.5 m (for semi-trailer coupled vehicles) (When loading on a full trailer-coupled vehicle) or 18 m (when loading on a full trailer-coupled vehicle).
[0063]
The fifth condition is that the inner width in the curtain width direction is about three times or more, preferably about six times or more, the width of the door mechanism. Here, the reference value of about three times is obtained when a door mechanism is provided at each end of the shutter curtain in the inner direction, and a door mechanism non-installed portion having a dimension width similar to these is secured between them. This is based on the fact that when it is more than such a value, it can be regarded as a shutter shutter for a large aperture. In addition, the reference value of about 6 times means that a door mechanism is provided one by one at intervals corresponding to the width of the door mechanism from both ends of the shutter curtain inwardly, and a dimension width similar to these (door) is provided therebetween. This is a numerical value obtained when securing a door mechanism non-installation part having the width of two parts of the mechanism), and if it exceeds this value, it can be regarded as a shutter shutter for large aperture It is.
[0064]
As a sixth condition, when the shutter device with the door mechanism of the present invention is a retractable shutter device that retracts and stores a shutter curtain on a winding shaft, the winding shaft is two or more in the axial direction. Is divided into two. In addition, after being manufactured in a divided state and transported to the construction site in the divided state, it is connected at the construction site to make one shaft, manufactured in the divided state, connected at the factory and connected After being transported to the construction site as a single shaft, after being manufactured integrally as a single shaft, and then cut and divided at the factory, and then transported to the construction site , Again connected at the construction site to form a single shaft, manufactured in a divided state, transported to the construction site in the divided state, and used continuously in the divided state at the construction site (In this case, the axis positions of the respective axes may be aligned or may be shifted in parallel. In this case, the shutter curtain is also of a split type, and the shutter in the split state when the shutter curtain is closed is operated. Ten is the concatenated or simply superposed with it Taking the configuration and the like are connected.), Etc. In such fasteners, also include any ones.
[0065]
As a seventh condition, in the case where the shutter device with the door mechanism of the present invention is a retractable shutter device that retracts and stores the shutter curtain around the winding shaft, the shutter device is disposed at an intermediate position in the axial direction of the winding shaft. At least at one position, a winding shaft and a supporting means such as an auxiliary roller for supporting a shutter curtain wound around the winding shaft to suppress bending of the winding shaft. Can be
[0066]
As described above, the present invention can be suitably applied to a shutter curtain for a large opening because, as the width of the shutter curtain increases, the arrangement of the door mechanism according to the situation of the building is realized and the door mechanism is used. There is a strong demand for a shutter device that is easy to use and convenient, and the greater the width of the shutter curtain, the greater the weight, making it difficult to handle during transport, construction, or manufacturing. Therefore, it is highly necessary to facilitate the handling according to the present invention.
[0067]
Further, among the shutter devices with a door mechanism described above, one of the most suitable configuration examples for the present invention includes the following configuration. That is, in the above-described inventions (including both the invention in which the door mechanism is arranged near the guiding means and the invention in which the door mechanism is arranged in the end section), the cover portion overlaps at least the cover portion of the curtain body. Each of the overlap margin portions is formed of a sheet-like member, and the shutter curtain has an inner dimension exceeding 12 m in the curtain width direction and is a shutter shutter for a large opening that partitions a space having a large cross-sectional width. Can be mentioned.
[0068]
Further, in the above description, the structure of the communicating portion in the shutter device with the door mechanism of the present invention may be an opening shape or a slit shape as described above, but it is particularly preferable to be as follows. That is, in the above-described invention (including both the invention in which the door mechanism is arranged near the guiding means and the invention in which the door mechanism is arranged in the end section), the communicating portion has an opening shape having a two-dimensional spread. It is preferable to have a side of a certain width that is formed and is arranged along the front end in the closing direction near the front end in the closing direction of the shutter curtain.
[0069]
Here, the front end in the closing direction of the shutter curtain refers to, for example, a portion provided with a seat plate, a weight, and the like. In addition, “opening having a two-dimensional spread” is intended to exclude slit-shaped ones, and “having a side having a certain width” means an inverted triangle having no side along the tip in the closing direction. The purpose is to exclude a shape such as a circle. Therefore, shapes such as a square, a rectangle, a triangle (the bottom is arranged along the front end in the closing direction), a trapezoid, an M-block cross-sectional shape, an inverted home base shape, a semicircle (the upper half of a circle), and the like are included.
[0070]
In the case of such a configuration, since the communication portion has an opening shape, the communication portion can pass through the communication portion more easily than in the case of the slit shape. For this reason, for example, in the case of a disaster prevention shutter device, evacuation is smoothly performed.
[0071]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0072]
First Embodiment FIG. 1 shows an elevation view of a disaster prevention shutter device 10 which is a shutter device with a door mechanism according to a first embodiment of the present invention, and FIG. A longitudinal sectional view (sectional view taken along the line AA in FIG. 1) is shown.
[0073]
The disaster prevention shutter device 10 is a shutter device having a disaster prevention function of partitioning an internal space of a building or the like in an emergency such as when a fire occurs and performing fire prevention and smoke prevention, and is provided, for example, in the middle of a passage space. Or, it is provided at a boundary position between the passage space and the hall space, and plays a role of forming a disaster prevention section. The disaster prevention shutter device 10 can partition a space having a large cross-sectional width in the left-right direction, and is a large-opening shutter device installed at a large opening in a building.
[0074]
In FIG. 1, the disaster prevention shutter device 10 includes a shutter curtain 20 that moves up and down to partition a space, a winding shaft 60 that winds up the shutter curtain 20, and left and right side edges of the shutter curtain 20 in FIG. Guide rails 70 and 71 are provided as left and right guides for guiding the vertical movement of the shutter curtain 20 when inserted, and a switch 80 including a motor and a brake for moving the shutter curtain 20 up and down and stopping.

Normally, the shutter curtain 20 is held in a retracted state wound around the winding shaft 60 by operating the brake of the switch 80, and in this state, a seat plate provided at a lower end portion of the shutter curtain 20 is provided. 22 is provided in a slit portion for passing the shutter curtain 20 formed in the ceiling 1 and rises to the position of the lintel so as to fit therein.
[0076]
On the other hand, in an emergency such as when a fire occurs, if a sensor (not shown) detects flame, smoke, heat, odor, and the like generated due to the fire or the like, the brake of the switchgear 80 is released by a signal from the sensor. It has become so. As a result, due to the weight of the shutter curtain 20 including the seat plate 22, the shutter curtain 20 is unreeled from the winding shaft 60 and descends, and reaches the fully closed state when the seat plate 22 reaches the floor 2. . It should be noted that instead of the automatic closing type using such a sensor, the brake of the switch 80 may be artificially released by lever operation or the like, or the automatic closing by the sensor and the manual operation by lever operation etc. are used in combination. It is good also as a structure which can be performed.
[0077]
When a switch or the like (not shown) is operated, the motor of the opening / closing device 80 is driven, whereby the take-up shaft 60 is rotated, the shutter curtain 20 is taken up by the take-up shaft 60 and rises, and the seat plate 22 is moved to the ceiling. When it reaches the position of the first lintel, the motor of the switch 80 is stopped and the brake is activated. It should be noted that, instead of such winding by motor driving, a structure in which winding can be performed manually by a chain pull operation, a lever operation, or the like may be employed.

These emergency entrances 30 to 32 are openings having a vertically long rectangular shape formed through the front and back of the curtain main body 21. Emergency doorways 30 to 32 are used to secure an evacuation route for people inside a building or the like in the event of an emergency such as a fire, that is, after the shutter curtain 20 is lowered due to a fire or the like, the disaster prevention section is provided. It is provided to secure a way for people who are left behind to escape, or to secure a path for rescuers and firefighters.
[0080]
The shutter curtain 20 is provided with cover sheets 40A to 42A and 40B to 42B which are cover portions for covering the emergency entrances 30 to 32 from both sides. Each of these two sheets, a total of six cover sheets 40A to 42A and 40B to 42B, has a vertically long rectangular shape, and the upper side thereof is sewn to the curtain body 21 above the emergency entrances 30 to 32. Being installed. The sewing portion 44 is formed by using a metal wire having fire resistance, for example, a stainless steel wire or the like as a sewing thread. The cover sheets 40A to 42A and 40B to 42B are all formed of sheet members made of the same material as the curtain main body 21, and have a sufficient disaster prevention function.
[0081]
Further, on each of the cover sheets 40A to 42A and 40B to 42B, a reinforcing metal wire or a metal rod (not shown) arranged so as to extend in the horizontal direction is provided at a position near the lower edge, or one in the vertical direction as appropriate. A plurality of the cover sheets are provided at appropriate intervals, whereby the bending of each of the cover sheets 40A to 42A and 40B to 42B can be suppressed, and each of the cover sheets 40A to 42A and 40B to 42B can have a shape maintaining function. After each of the cover sheets 40A to 42A, 40B to 42B is turned or pushed and enters and exits, each of the cover sheets 40A to 42A and 40B to 42B returns to the original state, and the entrances 30 to 32 are securely sealed. In addition, it is possible to exhibit predetermined fire prevention performance and smoke prevention performance.
[0082]
At the lower end of the shutter curtain 20, the metal seat plate 22 is provided as described above. The seat plate 22 is provided over substantially the entire width of the shutter curtain 20 in the width direction (left-right direction), and is also disposed at a lower position of each of the emergency entrances 30 to 32. The height dimension Z of the seat plate 22 is preferably, for example, 150 mm or less (see Article 112, paragraph 14, item 2 of the Building Standard Law Enforcement Order).
[0083]
One door mechanism 50 is constituted by the emergency entrance / exit 30 as one communication part and the cover sheets 40A and 40B as two cover parts. Similarly, the doorways 51 and 52 are configured by the emergency entrances 31 and 32 and the two cover sheets 41A, 41B, 42A and 42B, respectively. Therefore, a plurality (three) of door mechanisms 50 to 52 are arranged on the shutter curtain 20 in the curtain width direction (left-right direction). Each of the door mechanisms 50 to 52 allows the evacuee to pass through each of the emergency entrances 30 to 32 by turning or pressing the cover sheets 40A to 42A and 40B to 42B as shown by the two-dot chain line in FIG. Thus, the shutter curtain 20 can be moved from either side of the front and back spaces 3 and 4 to the other side. In addition, since the entire lower edge of each of the cover sheets 40A to 42A and 40B to 42B (the entire width) is separated from the seat plate 22, it is possible to easily enter and exit. Note that a part, but not all, of the lower edge may be separated from the seat plate 22. In short, at least a part (preferably the entirety) of the lower edge of the covering part is closed at the front end in the closing direction (here, the seat). If it is separated from the plate 22), it is easy to get in and out.
[0084]
The sizes and shapes of the plurality (three) of the door mechanisms 50 to 52 may be different from each other, but from the viewpoint of manufacturing and the like, it is preferable that all of them are substantially the same. The description will be made assuming that they are the same. Therefore, the width dimensions X1 to X3 and the height dimensions Y1 to Y3 of the emergency entrances 30 to 32 are all substantially the same, and the width and height dimensions of the cover sheets 40A to 42A and 40B to 42B. Are all substantially the same. In the first embodiment, the widths of the cover sheets 40A to 42A and 40B to 42B are also the widths α1 to α3 of the door mechanisms 50 to 52, and have a relationship of α1 ≒ α2 ≒ α3. As specific numerical examples of these dimensions, the width dimensions X1 to X3 of each of the emergency entrances 30 to 32 are preferably, for example, 750 mm or more, and the height dimensions Y1 to Y3 are, for example, 1800 mm or more. (Refer to Article 112, Paragraph 14, Item 2 of the Building Standards Law Enforcement Order). When the widths X1 to X3 are, for example, 750 mm, the widths (the widths of the door mechanisms 50 to 52) α1 to α3 of the cover sheets 40A to 42A, 40B to 42B are, for example, about 1100 mm. In such a case, the overlap margin 55 having a width dimension N of, for example, about 175 mm can be secured on both sides of each of the entrances 30 to 32.
[0085]
A handrail 5 is disposed between the left door mechanism 50 and the intermediate door mechanism 51 so as to extend in a direction perpendicular to the plane of FIG. 1, that is, to intersect with the shutter curtain 20.

[0086]
Here, of the portion occupying the inner width W of the shutter curtain 20, a portion near the left guide rail 70 is defined as an end section 20A, and a portion near the right guide rail 71 is defined as an end section 20B. Is a middle section 20C. The inner width W is the distance between the insides of the guide rails 70 and 71 on both sides, and the part of the entire width of the shutter curtain 20 in the curtain width direction that is swallowed by the guide rails 70 and 71 as the guide means. , That is, the width of the part exposed to the outside (the part visible from the spaces 3 and 4 partitioned by the shutter curtain 20). Specific values of the inner width W are, for example, about 6 times the width dimension α1 of one door mechanism 50 (for example, about 7 m when α1 ≒ 1100 mm, and about 13 m when α1 ≒ 2100 mm), Alternatively, it may be about 8 times (for example, about 9 m when α1 ≒ 1100 mm, and about 13 m when α1 ≒ 1600 mm).
[0087]
The left end section 20A is a portion occupying a position from the left end position B1 of the inner full width dimension W to a position B2 having a dimension width V1 toward the center position K in the curtain width direction. This dimension width V1 is "1/3" (here, 1/3) of the inner width W.
[0088]
The right end section 20B is a portion occupying a position from a right end position C1 of the full width W of the inner dimension to a position C2 having a dimension width V3 toward a center position K in the curtain width direction. This dimension width V3 is "1/3" (here, 1/3) of the total width W of the inner dimension.
[0089]
The intermediate section 20C is a portion occupying the position B2 to the position C2 and straddling the center position K in the curtain width direction. The dimension width Q1 of the intermediate section 20C is “N (N−2)” (here, one third) of the inner width W.
[0090]
The left door mechanism 50 is arranged so that the whole of the door mechanism 50 fits in the left end section 20A. The distance γ1 between the left end of the door mechanism 50 and the inner width end position B1 is equal to or smaller than the width dimension α1 of the door mechanism 50, and has a relationship of γ1 ≦ α1. Therefore, the door mechanism 50 is arranged near the left wall 6 on which the left guide rail 70 is provided, and is arranged near the handrail 5. Like the handrail 5, the wall 6 functions as a guiding means for guiding evacuees and the like in an emergency such as a fire.
[0091]
The door mechanism 51 at the intermediate position is disposed across the left end section 20A and the intermediate section 20C. The door mechanism 51 is arranged near the handrail 5.
[0092]
The right door mechanism 52 is arranged so that the entirety thereof fits in the right end section 20B. The distance γ3 between the right end of the door mechanism 52 and the inner width end position C1 is equal to or smaller than the width dimension α3 of the door mechanism 52, and has a relationship of γ3 ≦ α3. Therefore, the door mechanism 52 is disposed near the right wall 7 on which the right guide rail 71 is provided. Like the handrail 5, the wall 7 functions as guidance means for guiding evacuees and the like in an emergency such as a fire.
[0093]
A winding diameter adjusting member for adjusting the winding diameter when the shutter curtain 20 is wound and stored on the winding shaft 60 at an appropriate position in the curtain width direction as indicated by a two-dot chain line in FIG. 90 may be provided. Such a winding diameter adjusting member 90 is preferably formed of the same material and the same thickness as the cover sheets 40A to 42A and 40B to 42B.
[0094]
According to such a first embodiment, the following effects are obtained. That is, since the door mechanisms 50 and 52 are arranged in the left and right end sections 20A and 20B, the door mechanisms 50 and 52 can be arranged near the left and right walls 6 and 7. Therefore, it is possible to realize the arrangement of the door mechanism according to the situation of the building, that is, the arrangement of the walls 6 and 7 in the building, and to evacuate evacuees who are expected to evacuate while moving along the walls 6 and 7. Can be realized according to the behavior characteristics (movement characteristics) of the evacuees, and evacuees can be evacuated smoothly.
[0095]
The distance γ1 between the left end of the door mechanism 50 and the inner width end position B1 is equal to or less than the width dimension α1 of the door mechanism 50, and the right end of the door mechanism 52 and the inner width Since the distance γ3 from the width end position C1 is set to be equal to or less than the width dimension α3 of the door mechanism 52, the above-described effect can be further remarkable.
[0096]
In addition, since the door mechanisms 50 and 51 are arranged near the handrail 5 functioning as a guiding means, the behavior characteristics (movement characteristics) of the evacuees who are expected to be evacuated while moving while being guided by the handrails 5 are provided. ) Can be realized, and evacuees can be evacuated smoothly. Therefore, also in this respect, the arrangement of the door mechanism according to the state of the building, that is, the arrangement state of the guiding means in the building can be realized.
[0097]
Further, the end sections 20A, 20B in which the left and right door mechanisms 50, 52 are arranged are set to one third of the full width W of the inner dimension, and the intermediate section 20C is provided between them, so that the shutter is opened. The door mechanism is not necessarily provided without limitation over the entire inner width dimension W of the curtain 20. For this reason, it is possible to prevent a decrease in the strength of the shutter curtain 20, prevent air-tightness from lowering the smoke-shielding performance, and further reduce the labor and manufacturing cost in manufacturing. Therefore, it is possible to avoid inconvenience in manufacturing the shutter curtain 20. Therefore, it is possible to satisfy both the evacuee's request for smooth evacuation and the shutter curtain 20's manufacturer's request for avoiding manufacturing inconvenience.
[0098]
Further, the door mechanisms 50 to 52 provided on the shutter curtain 20 are disposed in the left and right end sections 20A and 20B or near the handrail 5, and are not disposed in other parts. It is possible to avoid disposing the door mechanism at a position that is not highly likely. Therefore, also in this respect, since the above-described inconvenience in manufacturing the shutter curtain 20 can be avoided, the requirements of both the refugee and the manufacturer can be further satisfied.
[0099]
And, as the width dimension of the shutter curtain 20 becomes larger, the gap between the demands of the refugees and the demands of the manufacturer becomes larger. realizable.
[0100]
In addition, since the shutter curtain 20 is configured by the curtain body 21 and the cover sheets 40A to 42A and 40B to 42B formed of a sheet-shaped member, the shutter curtain 20 can be reduced in weight and can be folded, so that it can be transported. It is possible to facilitate the handling at the time, at the time of construction, or at the time of manufacturing.
[0101]
Since the shutter curtain 20 is configured by the curtain body 21 and the cover sheets 40A to 42A and 40B to 42B formed of sheet-like members, the advantage increases as the lateral width of the shutter curtain 20 increases, and in particular, A disaster prevention shutter device 10 suitable for a disaster prevention shutter device provided in a large opening can be realized.
[0102]
Further, since the cover sheets 40A to 42A and 40B to 42B are sheet-like members, they can be sewn, and therefore can be easily attached to the curtain body 21.
[0103]
Furthermore, since the overlap margin 55 is formed by overlapping the curtain body 21 formed of a sheet-like member with the cover sheets 40A to 42A and 40B to 42B, airtightness can be easily secured.
[0104]

The left end section 220A is a portion occupying from the left end position D1 of the inner full width dimension W to a position D2 having a dimension width V4 toward the center position K in the curtain width direction. This dimension width V4 is "1 / N" (here, 1/4) of the inner width W.
[0111]
The right end section 220B is a portion occupying from the right end position E1 of the full width W in the inner dimension to a position E2 having a dimension width V5 toward the center position K in the curtain width direction. The dimension width V5 is "1 / N" (here, 1/4) of the inner width W.
[0112]
The intermediate section 220C is a portion occupying the position D2 to the position E2 and straddling the center position K in the curtain width direction. The dimension width Q2 of the intermediate section 220C is “N / (N−2)” (in this case, two-fourths, that is, one-half) of the inner width W.
[0113]
The left door mechanism 250 is arranged so that the whole of the door mechanism 250 fits in the left end section 220A. The distance γ4 between the left end of the door mechanism 250 and the inner width end position D1 is equal to or smaller than the width dimension α4 of the door mechanism 250, and has a relationship of γ4 ≦ α4. Therefore, the door mechanism 250 is disposed near the left wall 6 where the left guide rail 70 is provided. Note that unlike the first embodiment, the handrail 5 is not provided near the disaster prevention shutter device 200.
[0114]
The right door mechanism 251 is arranged so that the whole of the door mechanism 251 fits in the right end section 220B. The distance γ5 between the right end of the door mechanism 251 and the inner width end position E1 is set to be equal to or smaller than the width dimension α5 of the door mechanism 251, and has a relationship of γ5 ≦ α5. Therefore, the door mechanism 251 is arranged near the right wall 7 where the right guide rail 71 is provided.
[0115]
As in the case of the first embodiment, the winding diameter adjusting member 290 may be provided at an appropriate position in the curtain width direction as indicated by a two-dot chain line in FIG.
[0116]
According to such a second embodiment, the following effects can be obtained. That is, similarly to the case of the first embodiment, since the door mechanisms 250, 251 are arranged in the left and right end sections 220A, 220B, the door mechanisms 250, 251 are arranged near the left and right walls 6, 7. be able to. Therefore, it is possible to realize the arrangement of the door mechanism according to the situation of the building, that is, the arrangement of the walls 6 and 7 in the building, and to evacuate evacuees who are expected to evacuate while moving along the walls 6 and 7. Can be realized according to the behavior characteristics (movement characteristics) of the evacuees, and evacuees can be evacuated smoothly.
[0117]
And, similarly to the case of the first embodiment, the interval γ4 between the left end of the door mechanism 250 and the inner width end position D1 is equal to or less than the width dimension α4 of the door mechanism 250, and Since the distance γ5 between the right end of the mechanism 251 and the inner width end position E1 is set to be equal to or less than the width dimension α5 of the door mechanism 251, the above-described effect can be made even more remarkable. it can.
[0118]
Further, the end sections 220A and 220B in which the left and right door mechanisms 250 and 251 are arranged are set to ４ of the inner width W of the inner dimension, and between them, as in the first embodiment. Since the intermediate section 220C is provided, the door mechanism is not necessarily provided over the entire inner width dimension W of the shutter curtain 220 without limitation. For this reason, it is possible to prevent a decrease in the strength of the shutter curtain 220, prevent a decrease in the smoke shielding performance by ensuring airtightness, reduce labor in manufacturing, reduce manufacturing costs, and avoid inconvenience in manufacturing. . Therefore, both the evacuee's request and the manufacturer's request can be satisfied.
[0119]
Further, similarly to the case of the first embodiment, the door mechanisms 250 and 251 are arranged in the left and right end sections 220A and 220B and are not arranged in other parts, so that the necessity is not so high. Positioning of the door mechanism in the position can be avoided. Therefore, also in this respect, the above-described inconvenience in manufacturing can be avoided, so that the demands of both the refugee and the manufacturer can be further satisfied.
[0120]
Further, as the width of the shutter curtain 220 increases, the gap between the evacuee's request and the manufacturer's request increases, so the disaster-prevention shutter device 200 particularly suitable for the disaster-prevention shutter device provided in a large opening is used. realizable.
[0121]
Further, as in the case of the first embodiment, the shutter curtain 220 is constituted by the curtain body 221 and the cover sheets 240A, 240B, 241A, 241B formed of sheet-like members, so that the shutter curtain 220 can be adapted to a large opening and sewn. Thus, the cover sheets 240A, 240B, 241A, 241B can be easily attached to the curtain main body 221 and the airtightness can be easily ensured by overlapping the sheet members.
[0122]
Third Embodiment FIG. 4 shows an elevation view of a disaster prevention shutter device 300 which is a shutter device with a door mechanism according to a third embodiment of the present invention.
