Description

  The present invention relates to a shutter device that opens and closes an opening formed in a structure.

  A general shutter device has a shutter curtain in which a plurality of slats connected to each other are arranged in the vertical direction. When the shutter curtain moves downward and is placed at the curtain closing position, the shutter curtain closes the opening of the structure. When the shutter curtain moves upward and is arranged at the curtain opening position, the opening is opened. In recent years, there has been a demand for a shutter device capable of daylighting and guiding air even when an opening is closed by a shutter curtain. In general, when the shutter curtain is placed at the closed position, a part (or all) of the slats is rotated to form a gap between adjacent slats, and the indoor lighting and guidance are conducted through this gap. I'm doing the wind. That is, the shutter curtain is formed so that part or all of the slats can be rotated. Then, the slat is rotated between a slat open position where a gap is formed between adjacent slats and a slat closed position where the adjacent slats come into contact with each other and the gap is closed. When the slats are arranged at the slat open position, even when the shutter curtain is arranged at the curtain closed position, light and wind can flow through the gaps between adjacent slats. Therefore, it is possible to perform daylighting and air guiding into the room (for example, see Patent Document 1).

  By the way, in the shutter device proposed in Patent Document 1, the slat disposed at the slat open position has a hook shape whose end portion is directed downward toward the outdoor side. Therefore, the light that enters the room from the outside is blocked by the slats. Therefore, the shutter device introduced in Patent Document 1 has a problem that a sufficient amount of light cannot be secured.

  The applicant of the present application has applied for a shutter device that can increase the amount of light collected (see Patent Document 2). FIG. 8 is an explanatory diagram schematically showing a state in which the shutter curtain in Patent Document 2 is viewed from the side. As shown in FIG. 8A, when the shutter curtain 101 is disposed at the curtain closed position, each slat 110 is disposed at the slat closed position, and adjacent slats 110 are fitted to each other. As shown in FIG. 8B, when the shutter curtain 101 is arranged at the curtain closed position and the shutter curtain 101 is moved up by a predetermined length, the adjacent slats 110 are fitted to each other. Detach sequentially from top to bottom. Specifically, when the slat 110 located on the upper side is pulled upward, the distance between the pulled slat 110 and the slat 110 adjacent to the lower side opens, and the fitting allowance between the two slats 110 is reduced. Is disengaged. The disengaged slat 110 can be rotated. When the shutter curtain 101 is further moved up in this state, the locking pin 163 formed on the slat 110 is locked with the slat rotating means (not shown). When the shutter curtain 101 is further moved upward, the slat 110 rises and rotates with the locking pin 163 engaged with the slat rotating means, and the slat 110 is arranged at the slat open position shown in FIG. Is done. In the shutter device of Patent Document 2, the slat 110 that has been disengaged can be rotated at various angles. For this reason, if the shutter curtain 101 is moved up greatly and the slat 110 is rotated largely, the light entering the room from the outside is not blocked by the slat 110. Hereinafter, fitting between adjacent slats 110 is simply referred to as slat fitting.

By the way, in this kind of shutter device, when the shutter curtain 101 is moved upward by a predetermined length in order to rotate the slat 110x located above the shutter curtain 101, the shutter is disposed below the slat 110x to be rotated. A predetermined number of slats 110y are also pulled upward and disengaged. The disengaged slat is in a rotatable state. For this reason, when the shutter device receives a strong wind when the shutter curtain closes the opening and the slat 110x is disposed at the slat open position, the slat 110y may flutter, and noise may occur.

The first lock portion 45 and the second lock portion 39 are detachably joined when the lock means 4 is disposed at the lock position.

  The shutter device of the embodiment operates as follows.

  When the opening operation button of the controller is operated, the electric motor 72 is driven and the shutter curtain 1 is wound up and arranged at the curtain opening position. Accordingly, at this time, the opening is opened. When the closing operation button of the controller is operated, the electric motor 72 is driven and the shutter curtain 1 is drawn out and arranged at the curtain closing position. Accordingly, at this time, the opening is closed (FIG. 1).

  When the shutter device is in the state shown in FIGS. 2 and 7 (a), that is, when the shutter curtain 1 is arranged in the curtain closed position and each slat 10 is arranged in the slat closed position, the half-open operation button of the controller First, the electric motor 72 is driven. By driving the electric motor 72, the shutter curtain 1 is wound up and moved upward by a predetermined length. At this time, the slats 10 of the shutter curtain 1 are moved up in order from the one arranged on the upper side, and the slats 10 moved upward and the slats 10 adjacent to the lower side are disengaged (FIG. 7B). The disengaged slats 10x and 10y can be rotated. The slat 10z that is not disengaged does not rotate (FIG. 7C).

  The shutter device of the embodiment is provided with slat rotation means (not shown) having a known structure. The slat rotation means rotates the slat 10 by a mechanism similar to that disclosed in Patent Document 2 described above. The slat rotating means moves the shutter curtain 1 in which the opening / closing means 7 is disposed at the curtain closing position by a predetermined length, that is, as shown in FIG. When the fitting is disengaged, only the slat 10x is rotated and placed in the slat open position. In the shutter device of the embodiment, three slats 10 counted from above are arranged in the slat open position. Therefore, the shutter device of the embodiment can be in a half-open state. Furthermore, in the shutter device of the embodiment, the slat rotating means moves the opening / closing means 7 when the shutter curtain 1 arranged at the curtain closing position is moved upward beyond a predetermined length, that is, all the slats 10 are moved. When the fitting is disengaged, the slat 10 is rotated. Therefore, the shutter device according to the embodiment can take a fully open state in which the shutter curtain 1 closes the opening and all the slats 10 are arranged at the slat open position.

  By the way, as shown in FIG. 7c, the slat 10y disposed below the slat 10x disposed in the slat open position is an open / close slat and is disengaged. It can be rotated in the same manner as

  When the shutter device of the embodiment is in the half-open state shown in FIG. 7C, the first locking portion 45 of the locking device 4 is manually rotated by rotating the locking device 4 to the locking position shown in FIGS. And the second lock portion 39 of the side guide rail 30 are joined. Therefore, the lock means 4 is detachably fixed in the rotatable area A of the slats 10y and slats 10z. For this reason, the rotation of the slat 10 y that is disengaged and can be rotated is interfered with the locking means 4. Therefore, the rotation angle of the slat 10y is locked within a predetermined range (θ1 and θ2) as shown in FIG. Therefore, the shutter device of the embodiment can reduce fluttering of the slats even when a strong wind is received in the half-open state.

  In the shutter device of the embodiment, the locking means 4 disposed at the lock position is not in contact with the slat 10y, but is disposed at a position very close to the slat 10y. Accordingly, the locking means 4 allows the slat 10y to turn slightly, but locks the turning angle of the slat 10y within a sufficiently small range. Therefore, flapping of the slat 10 in the shutter device of the embodiment is sufficiently reduced. When the locking means 4 comes into contact with the slat 10y in the locked position, the slat 10y can be locked in the slat closed position. Therefore, in this case, flapping of the slat 10 can be further reduced.

  When the shutter device of the embodiment is in the fully opened state described above, if the lock unit 4 is manually rotated from the lock position to the retracted position, the lock unit is out of the rotatable region of the slats 10y and 10z. Because of the movement, the slats 10y and 10z can be rotated.

  In the shutter device according to the embodiment, the lock unit 4 is fixed to the side guide rail 30. However, for example, the lock unit 4 may be directly attached to the periphery of the opening. The method of moving the lock means 4 in and out of the rotatable area is not limited to rotation and slide. For example, the lock unit 4 may be detachably attached to any part of the guide frame 3. In this case, the lock means 4 may be attached to the guide frame 3 and moved into the rotatable area, and the lock means 4 may be detached from the guide frame 3 and moved out of the rotatable area.

  In the shutter device of the embodiment, the shutter curtain 1 is wound up and moved up by the opening / closing means 7 and is drawn out and moved down. For example, an opening / closing means that slides the shutter curtain 1 up and down may be used.

  As the first lock portion and the second lock portion, those having a known fitting structure or screwing structure may be used.

  The locking means 4 in the shutter device of the present invention can be attached to a conventional shutter device similar to that disclosed in the cited document 2. That is, when the locking means 4 in the shutter device of the present invention is attached to a conventional shutter device, the shutter device can be in a half-open state while reducing fluttering of the slats 10.
