Description

The present invention relates to a shutter case mounting structure for a window shutter, and an embodiment described later discloses a window shutter eave case mounting structure.

When installing a window shutter on the outdoor side of the window opening, guide rail base frames and guide rails are attached to both ends of the window opening in the width direction, positioned above both ends of the window opening in the width direction, and attached to the outer wall. On the other hand, left and right brackets in the form of take-out are attached, the winding shaft is supported between the left and right brackets, and the upper end of the shutter curtain is connected to the winding shaft. And the shutter case of a window shutter is attached above the window opening part on the outdoor side so as to cover the left and right brackets and the winding shaft.

When an eave is provided above the window opening, a so-called eaves case is attached as a shutter case. The conventional eaves case includes a plate-like upper surface, front surface, both side surfaces, and a lower surface, and has a rear surface formed of an open box. A rear piece for mounting is bent at the rear end of both side surfaces. The box-like eaves-top case is placed in the ceiling behind the eaves so as to cover the left and right brackets and the winding shaft. The eaves case is formed to have a projecting dimension larger than that of a normal shutter case, and the lower surface of the eaves case is removable so that maintenance of the window shutter is performed.

When attaching the eaves case, place the rear lower end of both sides of the eaves case on the upper end of the guide rail base frame of the window shutter and press the rear piece against the outer wall of the building frame and fix it with screws. However, it was difficult to fix the screws while holding the eaves case, and the workability was poor. In addition, since the eaves case has a large projecting dimension from the building frame, the front side of the eaves case is easy to rotate downward from the point of contact with the guide rail base frame. I am getting worse.

Also, when holding the eaves case by placing the lower rear end of both sides of the eaves case on the upper edge of the guide rail base frame of the window shutter, the mounting position in the left and right direction of the eaves case is determined accurately. It was difficult to attach to the housing.

Patent Document 1 discloses a shutter box that is attached with the upper surface protruding from the back of the eaves ceiling, and the lower cover part is removable. However, most of the shutter box and the winding shaft are more than the eaves ceiling. Located below. Further, Patent Document 1 does not have a viewpoint of improving the workability and mounting accuracy of mounting the shutter box.
