DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing device having an opening / closing member for partitioning a space and a fixed portion disposed around the opening / closing member, for example, a shutter device for forming a cool room. It can be used for an opening / closing device or the like which must secure a certain degree of airtightness.

[0002]

2. Description of the Related Art A shutter device is an opening and closing device that partitions a space by moving a shutter curtain as an opening and closing body.
Around the shutter curtain, as a device component, for example, a shutter case for storing the shutter curtain, a lintel provided near a slit formed in the ceiling for passing the shutter curtain, or a guide rail. It is common for a fixing part to be present.

Since the shutter curtain is movable, a gap is usually formed between the shutter curtain and a fixed portion such as the above-described shutter case due to the structure of the apparatus.

[0004]

However, as described above, if a gap is formed between the shutter curtain and the fixed portion, the following inconveniences may occur depending on the purpose and location of the shutter device. May occur.

For example, when a cool room is formed by using a shutter device, it is preferable that air does not flow between spaces on both sides partitioned by a shutter curtain. That is, it is necessary to secure airtightness by the shutter device. However, if a gap is formed between the shutter curtain and the fixed portion, air flows through the gap, and there is a possibility that proper airtightness according to the installation purpose of the shutter device cannot be secured.

[0006] Further, such inconvenience concerning ensuring airtightness is not limited to the case of a shutter device, depending on the purpose of installation of the device, but may be a door device having a door such as a sliding door or a hinged door, a roll screen device, a blind device, or the like. The same applies to other switching devices.

Further, for example, since a window shutter device or the like is installed in a place facing an external space, if a gap is formed between a shutter curtain and an entrance portion of a shutter case as a fixing portion, Small animals such as insects may enter the shutter case from the gap, and may cause malfunction, malfunction or contamination of the device. The inconvenience of invasion of such a small animal can occur not only in the case of the shutter device but also in other opening and closing devices depending on the installation location of the device.

[0008] Therefore, from the viewpoint of ensuring airtightness or preventing the invasion of small animals, various opening and closing devices including a shutter device are used in accordance with the installation purpose and installation location of the device.
In some cases, it is necessary to improve the shielding performance or the shielding performance of a device for partitioning a space.

An object of the present invention is to provide a switchgear capable of improving the shielding performance and the shielding performance.

SUMMARY OF THE INVENTION The present invention relates to an opening / closing device having an opening / closing body for partitioning a space and a fixing portion arranged around the opening / closing body. A gap that connects the spaces on both sides separated by the opening / closing body is formed between them, and at least one of the opening / closing body and the fixed portion is provided with a gap closing unit that closes at least a part of the gap. It is characterized by the following.

Here, the opening and closing device to which the present invention is applied is mainly a shutter device. In addition, a door device having a door such as a sliding door or a hinged door, a window device, the intrusion of smoke flowing along a ceiling, etc. This includes smoke-proof devices such as smoke-proof hanging curtains and smoke-proof hanging walls, and waterproof devices such as waterproof plates that prevent the intrusion of rainwater flowing along the floor. Therefore, in addition to the shutter curtain constituting the shutter device, the door such as a sliding door or a hinged door constituting the door device,
The window fitting body of the window device is included. Note that the former shutter device includes a shutter device in a broad sense such as a roll screen device and a blind device.

When the opening / closing device is a shutter device, the purpose of installation of the shutter device is arbitrary. For example, a shutter device for disaster prevention for fire prevention or smoke prevention, a shutter device for solar radiation shielding, It can be a shutter device for security purposes, a shutter device for forming a special space such as a dark room, a clean room, a cool box, a warm room, or the like.

When the opening / closing device is a shutter device, its installation location is arbitrary. For example, various door shutter devices such as ordinary ordinary houses, buildings, garages, factories, warehouses, cool storages, windows, etc. Shutter device, a shutter device provided in various buildings, such as a shutter device provided in the middle of a passage in a building or at a boundary position between a passage and a hall, or may be a shutter device provided in various buildings, for example, an underground mall, a station yard, a tunnel, etc. It is good also as a shutter device provided in various structures, such as inside and a ship.

Further, when the opening / closing device is a shutter device, the structure of the shutter device (including the storage system) is such that when the shutter curtain, which is the opening / closing member, is closed, the shutter curtain and the fixing portion are closed. Any space can be used as long as a gap is formed between the two spaces separated by the shutter curtain. 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-like member and this shutter curtain is wound around a winding shaft or folded and stored in a storage unit may be used. At this time, the shutter curtain may be formed by a single sheet-like member having substantially the same area as the area of the opening where the device is installed, or may be formed by sewing, bonding, welding, fasteners, buttons, or Velcro ( It may be formed by joining a plurality of sheet-like members with a joining tool such as a so-called magic tape (registered trademark)) or a soft magnet,
Further, a plurality of sheet-like members may be simply arranged without being joined. Further, a shutter device in which a shutter curtain is formed by connecting a large number of slats, and the shutter curtain is wound around a winding shaft of a storage unit and stored may be used. 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 a connected state. Further, a shutter device of a type in which the shutter curtain is wound and stored, or a shutter device in which a shutter curtain is formed of a single panel and this single panel is fed and stored may be used. The shutter device may be a shutter device in which the shutter curtain is formed by a plurality of pipe members connected to each other by a link member, or may be an overhead type shutter device (also referred to as an overhead door) for feeding and storing. Further, a blind shutter device in which a shutter curtain is formed by arranging a plurality of movable louvers in parallel may be used.
Also, for example, a shutter device of a type including a shutter curtain formed by combining various shutter curtains, such as a shutter curtain partially formed of slats and the remaining portion formed of a sheet-shaped member. May be.

The components and components of the various shutter curtains described above may be made of any material. If the material is a sheet-shaped member, for example, a cloth screen or a soft resin sheet such as vinyl chloride or urethane, Further, a sheet or the like formed of rubber or a rubber-like substance can be used. Slats, panels, link members, pipe members, louvers, and the like include, for example, metals such as steel, aluminum, and stainless steel, synthetic resins, and ceramics. , Wood, glass and the like can be used. When the sheet-like member is used for disaster prevention purposes such as fire prevention and smoke prevention, for example, a silica cloth or a glass cloth, or a fire-resistant paint or a water-resistant coating material as a fire-resistant coating material is sprayed or applied to these materials or An impregnated material or the like 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 such a case, the sheet is less likely to be damaged, and the durability of the sheet can be further improved, which is effective.

When the opening / closing device is a door device, the structure of the door device is such that when the door, which is the opening / closing member, is closed, the door is partitioned by the door and the fixed portion. It is optional as long as a gap that connects the spaces on both sides is formed. Therefore, the present invention is not limited to a normal sliding door or door-type door device, and may be a door device having a hanger guard suspended from an upper rail.
The installation location of the door device may be an entrance such as an entrance or an indoor room.

Further, the opening / closing direction of the opening / closing body such as a shutter curtain or a door may be any direction such as a vertical direction, a horizontal direction, a horizontal direction, an oblique direction, or a combination thereof.

The fixed portion means an immovable portion (a portion that does not move with respect to the space) of the opening / closing device. When the opening / closing device is a shutter device, a shutter case for accommodating a shutter curtain, a shutter. A lintel provided near a slit formed in a ceiling or the like for passing a curtain, a guide rail for inserting and guiding the end of a shutter curtain, and the like. Door bags to be stored, door frames arranged around doors, doors and doors etc. if doors are sliding doors, window frames etc. around window fittings when opening and closing devices are window devices Say. The structural body (building frame) itself, such as walls and floors, is considered to be part of the switchgear if it is necessary to achieve the purpose or function of the switchgear that partitions the space. It shall correspond to the fixed part.

The closed state means a limit position at which the opening / closing body does not move any more, or no need to move the opening / closing body further, based on the original purpose, function, or configuration of the opening / closing device. Means the state where it has moved to the limit position. This limit position is not limited to the case where the movement of the opening / closing body is restricted by mechanical / mechanical action, such as when the opening / closing body comes into contact with an object such as a floor and stops, as well as a rotary encoder and a limit switch. Mechanically as in the case where the movement range of the
In some cases, the movement of the opening and closing body is regulated and determined without depending on the mechanical action. For example, when the opening / closing device is a winding type shutter device that winds and stores a shutter curtain on a winding shaft, the shutter curtain is extended to a dispensing limit that the shutter curtain cannot be further extended from the winding shaft. (However, this is a state during normal use, and does not take into account a state during construction such as installation or replacement of a shutter curtain). Accordingly, a state where the opening and closing device is provided and the opening and closing body completely closes (for example, a state where the seat plate 21 is in contact with the floor surface 1 as shown in FIG. 1 described later) is cited as a main state. However, the present invention is not limited to this.For example, an opening / closing body such as a shutter curtain originally covers only a part of the opening, such as a smoke-proof hanging curtain that closes only a part of the opening close to the ceiling. , It means that only a part of the predetermined opening is closed. The same applies to the following when the opening / closing body is closed.

Further, "a gap is formed between the closed and closed body and the fixed portion, which connects the spaces on both sides partitioned by the open and closed body." It is only necessary that a gap is formed between the opening / closing body and the fixing portion when the opening / closing operation is performed, and does not mean that the gap is formed only when the opening / closing body is closed. Therefore, a similar gap is formed when the opening / closing body is set to a state other than the closed state, that is, when the opening / closing body is set to the open state, or when the opening / closing body is set to an intermediate state between the closed state and the open state. It is a purpose that may be done. The gap closing means only needs to close at least a part of a gap formed between the opening / closing body and the fixed portion when the opening / closing body is closed, and the opening / closing body is in the closed state. A similar gap formed between the opening / closing body and the fixed portion when the state is set to a state other than that described above does not necessarily need to be closed. However, a similar gap formed between the opening / closing body and the fixed portion when the opening / closing body is set to a state other than the closed state may be a gap closing unit that can close the gap.

In the following, simply "closing the gap"
In this case, the term may be used to mean not only that the entire gap is closed but also that at least a part of the gap is closed, including the case where only a part of the gap is closed.

In the present invention, at least a part of the gap formed between the opening / closing member and the fixing portion in the closed state is closed by the gap closing means. Therefore, in a state before the installation of the gap closing means, the spaces on both sides separated by the opening / closing body are in a communicating state due to the presence of the gap, but the width of the gap is reduced by the installation of the gap closing means. Alternatively, since there is no gap, the communication state is suppressed.

For this reason, the shut-off performance and the shut-off performance of the switchgear can be improved, so that the airtightness can be improved or the invasion of small animals can be prevented depending on the installation purpose and installation location of the device. These objects are achieved by these.

In the above-mentioned opening / closing device, the gap closing means is provided in the opening / closing body and is arranged at a position where it comes into contact with the fixing part when the opening / closing body is closed, and when the fixing part comes into contact with the fixing part. It is desirable to have a configuration that can be deformed according to the external shape.

When the gap closing means is configured to be deformable when it comes into contact with the fixing portion, the closeness of the gap closing means to the fixing portion is increased when the opening / closing body is closed. The gap formed between the opening / closing body and the fixed part can be more reliably closed, and the shutoff performance and the shutoff performance of the opening / closing device are further improved. It is suitable for doing so.

Further, as described above, when the gap closing means is configured to be deformable when abutting on the fixing portion, the gap closing means is formed by forming a flexible sheet member into a bag shape. It is desirable to have been.

Here, "a sheet-like member having flexibility"
For example, a sheet-like member made of cloth, rubber, synthetic resin such as vinyl chloride or urethane, paper, or the like can be used.

When the gap closing means is formed of a flexible sheet-like member in the shape of a bag, the gap closing means can be deformed according to the outer shape of the fixing portion when it comes into contact with the fixing portion. Can be easily realized, and it is possible to easily improve the shutoff performance and the shutoff performance of the opening / closing device, and particularly to easily secure the airtightness.

In the above-mentioned opening / closing device, the opening / closing body is provided with the first gap closing means, and the fixed portion is provided with the second gap closing means.
A configuration that is arranged at a position where it comes into contact with the second gap closing means when the opening / closing body is closed, and is deformable according to the outer shape of the second gap closing means when it comes into contact with the second gap closing means; It may be.

In the case where the first and second gap closing means are provided, the gap is closed by combining both the first and second gap closing means. It is possible to reduce the size of each of the two gap closing means, and accordingly, the degree of freedom in design is improved.

Further, as described above, in the case where the first and second gap closing means are provided, the first gap closing means is formed by forming a flexible sheet-like member into a bag shape. It is desirable that the second gap closing means is formed of a fixed member.

As described above, the first gap closing means is formed by forming a flexible sheet member into a bag shape.
When the second gap closing means is formed of a fixed member, the bag-shaped sheet-like member is deformed according to the outer shape of the fixed member when it comes into contact with the fixed member. It is possible to easily improve the shielding performance, particularly, secure the airtightness.

As described above, the present invention relates to a shutter device (including a shutter device in a broad sense such as a roll screen device or a blind device), a door device having a door such as a sliding door or a hinged door, a window device, and the like. However, the present invention is particularly suitable for closing a gap generated in a curtain storage portion of a shutter device. That is, in the opening / closing device described above, the opening / closing body is a shutter curtain, and the gap can be suitably applied to a case where the opening is formed in a curtain housing portion that houses the shutter curtain.

Here, the gap may be formed at the entrance portion of the curtain storage portion or at the inside thereof, or a case (also referred to as a box or a cover) covering the curtain storage portion. )) Does not matter.

In the opening / closing device described above, the opening / closing body is a shutter curtain wound and housed on a winding shaft, and the gap closing means is a plate-shaped member having one end rotatably attached to the shutter curtain. And a biasing unit configured to bias the plate-shaped member in a direction of expanding from a state where the plate-shaped member is arranged parallel or substantially parallel to the shutter curtain by separating the other end edge of the plate-shaped member from the shutter curtain. When the opening / closing body is opened, it may be wound around the winding shaft together with the shutter curtain, and when the opening / closing body is closed, it may be unwound from the winding shaft together with the shutter curtain and be expanded by the urging means. .

In the case where the gap closing means includes the plate-like member and the urging means as described above, a simple structure is used.
The gap can be closed, and the smoothness of the winding and feeding operation of the shutter curtain is not impaired.

Further, in the above-mentioned opening / closing device, the gap closing means may be detachably attached to the fixed portion.

In the case where the gap closing means is detachable as described above, the gap closing means can be attached later by installing the main body of the opening / closing device. For this reason, after installing the main body of the opening and closing device, it is possible to determine whether or not it is really necessary to attach the gap closing means, and to take measures according to the determination result. For example, if the opening / closing device is a window shutter device, after installing the main body of the window shutter device, it is checked whether small animals such as insects actually enter the curtain storage unit. If it seems to intrude, attach the gap closing means, while if it does not actually enter,
It is also possible to select to omit the installation of the gap closing means. Also, from the viewpoint of ensuring airtightness, it is possible to determine whether or not airtightness needs to be ensured even when the gap closing means is attached, and to take measures according to the determination result.

In the opening and closing device described above, the gap closing means is formed with an elongated hole through which the fastener is passed, and the gap closing means is attached to the fixing portion by the fastener passed through the elongated hole. It is desirable that the distance between the opening and closing member can be adjusted by changing the position where the fastener is passed in the elongated hole.

When the gap between the gap closing means and the opening / closing body is made adjustable by forming a long hole in the gap closing means as described above, it is possible to secure the required blocking performance and shielding performance while securing the gap closing capacity. An arrangement that minimizes adverse effects such as vibration of the gap closing means due to relative movement between the means and the opening / closing body can be realized.

In the case where the gap closing means is detachable as described above, it is preferable that the gap closing means is formed of a soft resin member.

When the gap closing means is formed of a soft resin member as described above, damage to the opening / closing body due to contact between the gap closing means and the opening / closing body can be suppressed.
Further, it is possible to suppress the generation of the vibration sound of the gap closing means due to the relative movement between the gap closing means and the opening / closing body.

Further, in the above-mentioned opening / closing device, the opening / closing body is a blind type shutter curtain formed by arranging a plurality of louvers side by side. The end louvers arranged at the positions may be provided with gap closing means.

In the case where the gap closing means is provided in the end louver as described above, when the shutter curtain is closed, the gap formed in the curtain accommodating section is provided by the gap closing means provided in the end louver. Is closed, and the shutoff performance and the shutoff performance of the switchgear are improved.

As described above, when the end louvers are provided with the gap closing means, the end louvers have the same or substantially the same shape as the louvers other than the end louvers among the plurality of louvers, In addition, it is preferable that a main body that moves in the same or substantially the same manner is provided, and the gap closing means is provided in a state of standing vertically or substantially vertically from the main body.

In the case where the end louver is provided with the main body and the gap closing means which rises vertically or substantially vertically from the main body, the end louver moves in the same manner as the other louvers. If the gap is closed, the gap can be closed without providing a particularly complicated mechanism or causing the end louver to move complicatedly.
