Description of the Related Art Heretofore, as this kind of sheet shutter, there has been known a sheet shutter comprising a windable shutter body and a winding device capable of winding the shutter body. Such a device is provided at an entrance of a building such as a factory or a warehouse, and when a vehicle or the like approaches, the winding device is automatically operated by a sensor to wind the shutter body at a high speed. In addition to allowing it to pass through, it is closed during normal times to minimize the outflow of cool and warm air and the intrusion of outside air to improve the air-conditioning effect. Savings.

[0003]

However, such a device is problematic when used in a building that is not fully equipped with air conditioning equipment, because on the contrary, the air permeability is poor. In particular, in summer, it was desired to circulate outside air to cool the inside of the building, but this was not achieved. The present invention
In view of the above-mentioned problems, it has been created to solve this problem, and an object of the present invention is to provide a seat shutter which can have air permeability as required.

[0004]

A seat shutter according to the present invention basically comprises a shutter body which can be wound, a winding device which can wind the shutter body, and a ventilation provided in a part of the shutter body. The present invention is characterized in that it comprises a unit and a windable cover detachably provided on the shutter body and capable of closing the ventilation unit.

When the shutter body is wound by the winding device, the entrance of the building is opened, and when the shutter body is unwound by the winding device, the entrance of the building is closed. When the cover is detached from the shutter main body, a ventilation portion appears in a part of the shutter main body, so that the ventilation is performed through the ventilation portion even when the shutter main body is in the closed state. When the cover is attached to the shutter body and the ventilation part is closed, the ventilation by the ventilation part is blocked. Therefore, the ventilation section can be opened and closed by attaching and detaching the cover, and ventilation can be performed by opening the ventilation section as needed.

[0006] The ventilation section may be constituted by a large number of small holes formed in a part of the shutter body. With this configuration, since only a large number of small holes are formed in the shutter main body, the present invention can be easily applied to existing shutters.

[0007] The ventilation portion is constituted by an opening formed in a part of the shutter main body, and a rollable perforated body provided in the shutter main body to close the opening and formed with a large number of small holes. May be. With this configuration, the perforated body can be made of a material different from that of the shutter body, and the strength of the opening can be prevented from being reduced.

The perforated body may be detachably provided on the shutter body, and the perforated body and the cover may be replaceable. With this configuration, since only one of the perforated body and the cover is attached to the shutter body, the thickness does not increase, the winding operation is performed smoothly, and the perforated body and the cover are damaged. In this case, these can be easily replaced with new ones.

[0009] The perforated body is made of an insect net or a fish net, and the cover is made of the same material as that of the shutter body, and is provided between the shutter body and the perforated body and between the shutter body and the cover, respectively. The detachable detachable tool provided may be a hook-and-loop fastener or a chuck. In this case, since a commercially available material can be used, the cost can be reduced.

And a winding shaft 15 rotatably provided around the horizontal axis inside the upper end of the shutter main body 2 to which the upper end of the shutter body 2 can be wound and wound, and a motor (electric motor) provided in the shutter case 14 for rotating the winding shaft 15 16, a sensor (ultrasonic sensor) 17 provided on the side frame 13 for detecting that an automobile or the like approaches, and a sensor 1 provided on the side frame 13.
Control panel 18 for controlling motor 16 based on signals from
And a reflection mirror 19 provided on the side frame 13.

The ventilation part 4 is provided in a part of the shutter main body 2. In this example, a relatively large opening 20 formed in a part of the shutter main body 2 is closed by a front side thereof. For this purpose, the shutter body 2 is configured to be detachably provided on the shutter body 2 and has a relatively small (smaller than the opening 20) small number of small holes 21 formed therein. Opening 20
Are closer to the lower part of the shutter body 2 (between the second pipe 7 from the bottom and the third pipe 7 from the bottom) and upper part (between the first pipe 7 from the top and the second pipe 7 from the top). , And is divided into three sections in the left-right direction for each location, and is composed of a total of six things. The perforated body 22 is formed of a wind-up insect repellent net made of metal or synthetic resin, and has a size slightly larger than each opening 20. A detachable attachment 23 is provided between the shutter body 2 and the perforated body 22. The attachment / detachment tool 23 is fixed to the surface of the shutter body 2 located around each opening 20 by sewing, bonding, fusion or the like, and fixed to the back surface of each perforated body 22 corresponding thereto. A hook-and-loop fastener 24 and a detachable hook-and-loop fastener 25 are provided.

The cover 5 is detachably provided on the shutter body 2 and can be wound up to close the ventilation section 4. In this example, the cover 5 is replaceable with the perforated body 22.
A removable attachment 26 is provided between the shutter body 2 and the cover 5. That is, the cover 5 is formed of two upper and lower members that close the upper and lower two openings 20 formed in the shutter body 2 and is made of the same material as the shutter body 2. And the attachment / detachment tool 2

Next, the operation will be described based on such a configuration. When an automobile or the like approaches, the sensor 17 of the winding device 3 detects the approach and the motor 16 is operated by the control panel 18. When the motor 16 is operated, the winding shaft 15 is rotated and the shutter main body 2 is wound up at a high speed (for example, 0.7 m per second), so that the entrance B of the building A is in an open state and the passage of a car or the like is performed. Allow. During normal times, the shutter body 2 is rewound by the winding device 3 and the entrance B of the building A is closed. As shown in the upper part of FIG. 1, when the perforated body 22 is mounted on the shutter body 2 by the attachment / detachment tool 23, even if the shutter body 2 is in the closed state, the many small holes 21 of the perforated body 22 are closed. Ventilation is provided through. As a result, in summer, for example, outside air can be circulated to cool the inside of the building A. As shown in the lower part of FIG. 1, when the cover 5 is mounted on the shutter main body 2 by the attachment / detachment tool 26 instead of the perforated body 22, the opening 20 is closed by the cover 5, so that ventilation is blocked. Is done. As a result, in winter, for example, the flow of outside air can be cut off to prevent a temperature drop inside the building A. Therefore, the opening 20 of the ventilation section 4 can be opened and closed by attaching either the perforated body 22 or the cover 5 to the shutter main body 2, and ventilation can be performed by opening the opening 20 of the ventilation section 4 as necessary. You can do it.

As shown in FIG. 1, when there are a plurality of vents 4, a part of them can be closed and covered by a cover 5. By doing so, the ventilation position and the ventilation amount can be adjusted. Since both the perforated body 22 and the cover 4 are made of a material that can be wound, even if they are wound together with the shutter main body 2, there is no hindrance to the winding operation. Since either the perforated body 22 or the cover 4 is attached to the shutter main body 2, it is possible to reinforce the reduction in strength due to the formation of the opening 20, thereby improving the durability. In the case where the perforated body 22 is made of an insect repellent net, an insect repellent effect can be expected.

In the above example, the ventilation portion 4 is constituted by the opening 20 and the perforated body 22. However, the invention is not limited to this. For example, a large number of small holes formed in a part of the shutter body 2 are provided. You may comprise. In the above example, the ventilation portions 4 are provided at two locations above and below the shutter body 2, but the invention is not limited to this, and one or three or more locations may be provided. In the above example, the ventilation part 4 is divided into three sections in the left-right direction for each location. However, the invention is not limited to this, and one section or four or more sections may be used. The cover 5 is, in the above example,
Although the one that covers the three divided ventilation parts 4 at a time, it is not limited to this, and for example, three parts that are divided for each division of the ventilation part 4 may be used. In the above example, the cover 5 is made of the same material as the shutter body 2, but is not limited thereto, and may be made of a material different from that of the shutter body 2, for example. The perforated body 22 is an insect repellent net in the above example, but is not limited thereto, and may be a fish net, for example. In the above example, the attachment / detachment tools 23 and 26 are the hook-and-loop fasteners 24, 25 and 27, but are not limited thereto, and may be, for example, chucks or the like. The cover 5 and the perforated body 22 are provided on the front surface of the shutter main body 2 in the above example, but are not limited thereto, and may be provided on the back surface of the shutter main body 2, for example.
