Therefore, when the shutter is open, there is a problem that foreign matter such as dust, insects, leaves, etc. will enter the inside from the entrance and exit, which will contaminate the slat curtain and cause malfunction of the mechanism part. In some cases, it may get down, and there is the problem that no measures have been taken against waterproofness.

In order to solve the above problems, the present invention provides a slat curtain entrance / exit structure in which the entrance / exit of the slat curtain storage unit can be opened / closed by using the operation of the slat curtain when the shutter is opened / closed. It is intended to be provided.

[0005]

[Means for Solving the Problems]

 Next, means for achieving the above object will be described with reference to the drawings corresponding to the embodiments. The structure of the entrance and exit of the slat curtain according to the present invention is a pull-up shutter device in which the storage portion 3 of the slat curtain 2 is provided below the shutter opening 1 and the shutter opening 1 is closed by pulling up the slat curtain 2. In the opening 3A provided on the upper surface 3a of the storage portion 3, at least the inside of the shutter opening 1 is pivotally attached to open and close the opening 3A, and when the opening 3A is opened, the door 3A is opened. The skirting board 2A is provided with a lid 6 having a hook portion 6A projecting therefrom and an engaging portion 9 projectingly formed on the skirting board 2A at the upper edge of the slat curtain 2 and engaging the skirting board 2A when the shutter is opened. It is characterized in that the joint portion 9 is engaged with the hook portion 6A of the lid body 6 to rotate the lid body 6 to the closing side.

[0006]

[Action]

 Therefore, when the shutter is opened, the engaging portion 9 projectingly formed on the skirting board 2A at the upper edge of the slat curtain 2 engages with the hook portion 6A of the lid body 6, and the slat carten 2 enters the storage portion 3. At this point, the lid 6 closes the entrance 3A of the storage unit 3. Further, when the shutter is closed, the lid 6 is pushed away by the skirting board 2A at the upper edge of the slat curtain 2 to open the doorway 3A. For this reason, when the shutter is opened, foreign matter such as dust and tree leaves is prevented from entering the storage section 3, and rainwater is prevented from entering, so that anxiety about waterproofness can be eliminated.
