[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a shutter curtain in which a plurality of panels are connected to each other at a vertical interval with a vertical interval, and the opening portions are sequentially stacked and the shutter curtains are sequentially closed. It relates to a panel shutter that raises while keeping a space between them and stores them in parallel on the ceiling side to open the opening. Specifically, it relates to a smoke exhaust type panel shutter with a ventilation function for smoke emission in the shutter curtain. Is.

[Conventional technology]

Panel shutters are used for partitioning large spaces such as banquet halls, auditoriums, restaurants, and conference rooms, as well as openings around the exterior of buildings and aisles in underground malls.

In a typical panel shutter, a shutter curtain is constructed by connecting both side edges of multiple panels in series with a roller chain.The shutter curtain is hung and suspended in conjunction with forward and reverse rotation of a sprocket engaged with the roller chain. The openings are closed and opened, but when hanging, each panel is guided by guide rails standing on both sides of the opening and arranged in a vertical plane to close the opening. Are sequentially fed into storage rails provided in the front-rear direction and stored in parallel to open the opening.

[Problems to be solved by the device]

However, when the panel shutter is used as a partition or an opening around the outside of the building as described above, it completely partitions the room or opening, and is used when ventilation or an exhaust port is required. There were restrictions. Therefore, it is conceivable to remove the uppermost panel of the shutter curtain and form the opening in the shutter curtain, but there is a problem in terms of crime prevention in the case where the shutter curtain is mounted around the outside of the building. Although it is conceivable to form a through hole in the face plate of the panel itself, forming a through hole in a steel plate panel lowers wind pressure resistance. When the wind pressure is applied to the panel when it is closed, the panel strength is reduced such that the panel is bent, so that it cannot be used.

The present invention has been made in view of the above problems, and provides a smoke exhaust type panel shutter that can illuminate and emit smoke with reliable ventilation without causing a problem in crime prevention and a decrease in panel strength. It is intended to be provided.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, this invention suspends both side edges of a plurality of panels with a roller chain via a support shaft provided with guide rollers at the tips, and ascends and descends along the guide rollers by forward and reverse rotation of the sprocket. In the panel shutter in which the movement and the lateral movement along the storage rail are performed, when the panel shutter is closed, in the space formed between the upper end of the uppermost panel and the panel swallowing opening,
In order to provide a ventilation part that flexibly connects a plurality of pipes that are laterally arranged at a predetermined interval by a link material, the ventilation part is provided at least at both side edges of the upper and lower pipes, and a guide roller is provided at the tip. A ventilation part is formed by connecting the roller chain through the upper and lower support shafts, and the guide roller connected to the upper and lower end pipes when the panel shutter is housed is guided by the housing rail so that the ventilation part is bent and housed. This is a smoke exhaust type panel shutter.

[Action]

According to this invention, since the ventilation part connecting the aggregates is formed at the uppermost part of the shutter curtain, ventilation and smoke can be exhausted even when the shutter curtain is fully closed. In addition, the top of the shutter curtain is not an opening for one panel, but a ventilation part that connects aggregates,
There is no security problem because it is impossible to pass through, and unlike the case where a through hole is formed directly in the panel, the strength of the panel is not reduced, and a greater smoke exhausting ability and daylight are obtained compared to the through hole. It becomes possible.

The lowermost panel 1e stops before the sprocket 9, and the shutter curtain B is fully opened by operating the upper limit switch. Next, in order to close the shutter curtain B in the fully opened state, the chain 12 is extended by operating the opening / closing device 12 contrary to the above-described opening operation, and the sprocket 9 is successively passed over from the bottom panel 1e. The lowermost panel 1e comes into contact with the floor and stops at a predetermined interval, and then the upper panel 1 is closed in a stacked manner. In the descending operation, the restricting body 20 of the sub-guide D is spread by the entry of the panel 1, and after passing, it is projected by a certain amount by the urging force of the coil spring 21.
When the pipe 5 of the ventilation part C is lowered, the width of the guide rail 7 is reduced to suppress rattling of the pipe 5 as shown in FIG. 4, and noise generation is also reduced. Also,
Even when fully closed, rattling of the pipe 5 due to wind or the like can be suppressed. Even if the shutter curtain B is fully closed, the ventilation part C connecting the pipes 5 is provided on the upper part of the shutter curtain B, so that each partitioned room is in a communicating state in which ventilation is possible, which may lead to security problems and panel strength. Efficient smoke emission is performed without causing deterioration. Moreover, since the aperture ratio is large, sufficient light can be obtained.

[Effect of device]

Since this invention is configured as described above, not only can the panel shutter provide ventilation, smoke emission, and daylighting functions, but the ventilation part provided at the top of the shutter curtain is stored in a bent state, so that the panel pitch is not less than The ventilation part can be formed. In addition, since the upper and lower ends of the ventilation part are connected to the roller chain, when the shutter is fully closed from the fully open state, the ventilation part is guided by the roller chain connected to the top floor panel and from the storage rail to the shutter swallow opening. It is surely guided and can perform a good opening and closing operation.
