Description

  The present invention relates to a shutter, and more particularly to a shutter that can reliably prevent rainwater from entering a building.

In recent years, a shutter that covers the opening from the outdoor side is often attached to the opening of the wall constituting the building. An example of such a shutter is disclosed in Patent Document 1. FIG. 6 is a longitudinal sectional view showing a main part of a conventional shutter. As shown in FIG. 6, the conventional shutter 100 includes an upper frame 11, a lower frame (not shown), left and right vertical frames (not shown) extending upward from the upper frame 11, and left and right vertical frames. A frame body 10 having a roof plate 15 for connecting the upper end portions of each other is provided. Between the upper frame 11 and the lower frame 12 in the frame body 10, a glass shoji, a screen door, etc. are attached. Further, between the upper frame 11 and the roof plate 15 in the frame body 10, a shutter main body 20 having a shutter winding portion 22 that winds and lowers the slat 24 and a shutter box 30 that houses the shutter winding portion 22. Is arranged.
JP 2004-19138 A

In such a shutter 100, for example, when slats 24 are closed, wind and rain are blown from the outdoor side (the right side in FIG. 6), and rainwater from the wind and rain is blown to the shutter body 20 side. As shown by the arrow A, it is possible for the rainwater blown up to enter the wall of the building from between the roof plate 15 and the shutter box 30 to the indoor side of the shutter box 30 (left side in FIG. 6). There is sex. In some cases, this rainwater may enter the glass screen / screen door below the shutter box 30. The rainwater that has entered in this way causes deterioration of the building wall and stains such as glass screens and screen doors. In particular, when the wall body is made of a lightweight aerated concrete (ALC) panel, the frame is generally attached to the ALC panel with bolts. Since rainwater enters and the ALC panel absorbs moisture, the heat insulation and sound insulation properties of the wall body are remarkably deteriorated.
Therefore, conventionally, when the shutter 100 is attached to the opening of the wall of the building, a seal member such as a steel plate or a sheet is pasted on the indoor side of the frame 10, that is, between the frame 10 and the wall. The sealing member prevents rainwater from entering the wall.

However, depending on the level of proficiency of the installation operator, the method of attaching the seal member may be insufficient, or the application of the seal member itself may be forgotten. In these cases, rainwater enters the building side. May degrade the building.
An object of the present invention is to provide a shutter that can reliably prevent the ingress of rainwater to the building side and suppress the deterioration of the building without depending on the installation work at the site.

  The present invention includes a frame having an upper frame, a lower frame, left and right vertical frames extending upward from the upper frame, and a roof plate connecting upper ends of the left and right vertical frames; A shutter comprising a shutter main body disposed between the upper frame and the roof plate in a frame, wherein the shutter main body has a shutter box that houses a shutter winding unit that winds and lowers a slat, A seal member for closing a space between the upper surface of the upper plate of the shutter box and the lower surface of the roof plate is attached.

  According to the present invention, even if rain and wind is blown up in a state where the slat is closed and rainwater is blown into the shutter box, the upper surface of the upper plate of the shutter box and the lower surface of the roof plate are Since the sealing member for closing the gap is provided, rainwater does not enter the building side through the gap between the upper plate and the roof plate. In addition, since the seal member is not disposed between the shutter and the building as in the prior art, the seal member is disposed between the upper plate and the roof plate. The seal member can be attached to the body, and in this case, it is not necessary to perform the work of attaching the seal member on site. Therefore, it is possible to reliably prevent rainwater from entering the building and to suppress deterioration of the building without depending on the installation work at the site.

  Here, it is possible to adopt a configuration in which the base end side of the seal member is attached to the lower surface of the roof plate and the front end side abuts on the outdoor side end portion of the upper plate of the shutter box. According to such a configuration, since the front end side of the seal member abuts on the outdoor side end portion of the upper plate of the shutter box, the rainwater blown up does not enter the upper plate of the shutter box and enters the building side. Infiltration of rainwater can be prevented more reliably.

Further, in the shutter, the seal member has a base end attached to the lower surface of the roof plate, and a distal end abutted against the upper surface of the upper plate of the shutter box, and at least in the upper plate of the shutter box, An inclined surface that is inclined downward toward the outdoor side direction may be formed in a portion on the outdoor side of the contact portion of the sealing material.
According to such a configuration, the rainwater blown up enters the contact portion of the sealing member of the upper plate, but is blocked by the sealing member, and then travels along the inclined surface of the upper plate to the outside of the shutter box. Is discharged. For this reason, it is possible to prevent rainwater from entering the building.

  In the shutter described above, an inclined surface that is inclined downward toward the outdoor side direction may be formed on the upper frame. According to such a configuration, for example, when the lower part of the shutter box is opened, rainwater that has entered the shutter box flows to the upper frame, but the rainwater travels along the inclined surface of the upper frame and the shutter. Since it is discharged to the outside of the box, rainwater does not stagnate inside the shutter box, and it is possible to prevent the inside of the shutter box from becoming unsanitary or soiling.

  According to the shutter of the present invention, there is an effect that the deterioration of the building can be suppressed by reliably preventing the intrusion of rainwater into the building without depending on the installation work at the site.
