BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an entrance / exit structure of a slat curtain in a pull-up shutter device used for a ventilation opening of a building such as a house or a lighting window.

[0002]

2. Description of the Related Art A wind-up cage for winding a slat curtain is provided at the upper edge of a shutter device used for a ventilation opening of a building such as a house or a lighting window due to structural restrictions of the building. Because it may not be possible, it is convenient to provide a storage unit (shutter case) with a built-in take-up cage below the shutter opening. A pull-up shutter device configured to pull out a slat curtain is provided.

[0003]

However, the above-mentioned pull-up type shutter device does not have a mechanism for closing the entrance and exit of the slat curtain provided on the upper surface of the storage portion. Therefore, when the shutter is open, foreign substances such as dust, insects, and leaves enter the inside from the entrance,
There is a problem that the slat curtain is soiled and causes a failure of a mechanism part. In addition, rainwater or the like may fall down, and there is a problem that no countermeasure is taken for waterproofness.

Accordingly, the present invention provides an entrance / exit structure for a slat curtain in which the entrance / exit of a slat curtain storage portion can be opened / closed by utilizing the operation of the slat curtain when opening / closing a shutter in order to solve the above-mentioned problems. It is intended to be.

[0005]

Next, means for achieving the above object will be described with reference to the drawings corresponding to the embodiments. The entrance / exit structure of the slat curtain according to the present invention has a retractable shutter device in which a storage unit 3 for a slat curtain 2 is provided below a shutter opening 1 and the slat curtain 2 is pulled up to close the shutter opening 1. , The door 3A provided on the upper surface 3a of the storage section 3 is pivotally connected at least with the inside of the shutter opening 1 as a fulcrum to open and close the door 3A, and to open and close the door 3A.
A in which a hook portion 6A protruding toward A is formed.
And an engaging portion 9 protruding from the skirting board 2A at the upper edge of the slat curtain 2. The engaging portion 9 of the skirting board 2A engages with the hook portion 6A of the lid 6 when the shutter is opened. Thus, the lid 6 is turned to the closing side.

[0006]

Therefore, when the shutter is opened, the engaging portion 9 protruding from the skirting board 2A at the upper edge of the slat curtain 2 engages with the hook portion 6A of the lid 6, and the slat curtain 2 is stored in the storage portion 3. At the time when the entrance 3 enters the entrance 3 of the storage section 3 with the lid 6.
Block A. 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, and the entrance 3A is opened. For this reason, when the shutter is opened, foreign substances such as dust and leaves are prevented from entering the storage unit 3, and at the same time, rainwater is prevented from entering, and concerns about waterproofness can be eliminated.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the illustrated pull-up shutter device. In the shutter device of the present invention, as shown in FIG. 1, a slat curtain 2 for opening and closing a shutter opening 1 is provided inside a slat curtain storage unit (shutter case) 3 arranged below the opening 1. The winding cage 4 is wound up.

An entrance 3A through which the slat curtain 2 enters and exits is provided on the upper surface 3a of the storage section 3. One side of the entrance (indoor side) of the entrance 3A is a lintel 8. A pair of left and right guide rails 5 and 5 'for guiding the slat curtain 2 up and down are provided on both sides of the shutter opening 1 so as to face each other.

As shown in FIGS. 1 and 2, a lid 6 for opening and closing the entrance 3A is provided with a lintel 8 inside the opening 1 at the entrance 3A located on the upper surface 3a of the storage portion 3 of the slat curtain. Is pivotally mounted on a pivot 7 with its side as a fulcrum. When the shutter is closed, this lid 6
Is in an open state as shown in FIG. 2 and is superposed on the upper surface of the lintel 8.

The lid 6 is formed with a hook 6A extending toward the entrance 3A and facing the entrance 3A in an open state in which the lid 6 is overlapped with the lintel 8.

As shown in FIG. 2, the skirting board 2A, which is the upper edge of the slat curtain 2, has a lid 6 on its inner side, that is, on the indoor side which is the lintel 8 side. A protruding engaging portion 9 facing the hook portion 6A is formed so as to protrude. When the shutter is opened, the engaging portion 9 is engaged with the hook portion 6A of the lid 6 from above to cover the hook 6A.
Is rotated to the closing side.

In such a configuration, when the shutter is opened, the slat curtain 2 descends so that the engaging portion 9 projecting from the skirting board 2A at the upper edge of the slat curtain 2 causes the lid 6 to be opened.
The cover 6 is rotated (arrows in the figure) as shown in FIG. 3 and the entrance 3A of the storage section 3 is closed by the cover 6 as shown in FIG.

When the shutter is closed, the slat curtain 2 is pulled upward from the storage section 3 through the entrance 3A. At this time, as shown in FIG. The lid 6 is pushed up from below. Then, as shown in FIG. 2, the door 3A is opened by tilting the lid 6 toward the lintel 8 side.

In this way, the door 3A of the storage section 3 can be opened and closed by the lid 6 in conjunction with the opening and closing of the shutter, that is, the operation of the slat curtain 2.

As shown in FIG. 6, the engaging portion 9 projecting from the skirting board 2A may be a ridge extending over the entire width of the skirting board 2A, or as shown in FIG. It may be a piece shape to be attached.

If the upper edge frame of the shutter opening 1 is formed obliquely due to structural restrictions, and the shape of the slat curtain 2 is not rectangular but triangular or trapezoidal with a hypotenuse, the engaging The part 9 may be provided on the baseboard 2A in the shape shown in FIG. 8 or FIG. 9 as described above.

Further, as shown in FIG. 10, the shape of the hook portion 6A provided on the lid 6 is formed in a long convex strip shape corresponding to the width of the slat curtain 2 similarly to the engagement portion 9. Alternatively, as shown in FIG. 11, a piece shape formed on a part may be used.

Further, in the above-described embodiment, the example in which the lid 6 is provided inside (the lintel 8) on the indoor side of the shutter opening 1 has been described, but it may be provided on the outside on the outdoor side.
Furthermore, it is needless to say that it may be provided opposite to both sides of the entrance 3A.

[0019]

As described above, the shutter curtain entrance / exit structure according to the present invention has a slat curtain which is pivotally attached to the entrance / exit of the storage section provided below the shutter opening. When it descends and opens, it can close the entrance of this storage part, which prevents foreign substances such as dust, insects and leaves from entering from the entrance, prevents rainwater from entering, and eliminates concerns about waterproofness The slat curtain is not soiled or rusted in the storage part because practical effects such as the slat curtain can be obtained and the intrusion of these is prevented.

A hook protruding from the lid,
When the shutter is opened, the engaging portion of the skirting board engages with the hook portion of the lid, and the lid is rotated. Because it has a simple structure that closes the entrance, it saves space and facilitates construction and maintenance, and because it is a mechanism that accompanies this operation without disturbing the opening and closing operation of this slat curtain. In addition, an excellent effect that the opening and closing operation is reliably performed is exhibited.

Further, since the entrance and exit of the slat curtain are closed when the shutter is opened, there is an effect that the appearance of the shutter opening is improved.
