Description

  The present invention relates to a shutter device provided in a building opening.

  As a shutter device, for example, as in Patent Document 1, a shutter body is provided above a building opening, and a slat is moved up and down along a guide rail provided in the opening. The shutter device usually has a shutter main body, a frame for mounting the shutter main body, a shutter box covering the shutter main body, and a shutter vertical frame (including a guide rail and an opening vertical frame) provided below the shutter main body.

When the shutter device is installed on site, the shutter main body is provided at a high place above the building opening as described above, and therefore the construction work tends to be difficult in a heavy shutter device. In addition, since the shutter device has a sliding member such as a slat as described above, it easily deteriorates over time, and for maintenance, the shutter body and the shutter box are often required to be removed and newly attached. Therefore, a shutter device with high workability is required.
Further, in order to provide the shutter device, a storage portion of the shutter main body is required above the building opening, and the lighting area of the opening must be reduced as compared with the case where the shutter device is not provided. Therefore, there is a need for a shutter device that does not affect the lighting area of the opening as much as possible.

  On the other hand, since the shutter device is provided exposed outside the room, it affects the exterior of the building. In a diversifying society, the design of the details of the shutter device is often required.

  For example, in Patent Document 2, in a left and right frame having an inner wall and an outer wall, a hollow portion is formed in the prospective direction of the rigid frame by connecting the two walls with an intermediate wall, and By cutting out the upper part at a part corresponding to the wall surface of the hollow part on the outdoor side, a storage space for receiving the end of the shutter take-up part is formed in the upper part of the rigid frame, and the end of the shutter take-up part A shutter frame structure has been proposed in which the portion is supported by the wall surface of the hollow portion on the indoor side.

  According to the structure of the shutter frame described in Patent Document 2, it is possible to secure a shutter storage area and support the weight of the shutter part, and to suppress the finding dimension of the guide rail and to increase the lighting area of the opening part. It is described. However, when constructing on-site using this structure, first, the weight of the shutter body is supported by placing the lower part of the shutter body on a rigid frame, and then the shutter body is fixed by screwing or the like. That is, before screwing the shutter body, the shutter body may be tilted and fall down depending on the center of gravity of the shutter body, and the shutter body must be pressed against the building side. Therefore, there was room for improvement in the on-site workability of the shutter body.

  In addition, in the structure where the lower part of the shutter body is supported by the shutter vertical frame (a structure in which the support piece is attached to the vertical frame side), the direction in which the shutter vertical frame is located in order to ensure strength according to the shape of the support piece The width must be increased, and the lighting area of the opening is reduced. Therefore, there is room for improvement in securing a larger lighting area.

  On the other hand, with respect to the shutter box, it can be said that a construction in which a screw hole is provided at the lower part of the shutter box and a screw head faces downward as described in Patent Document 2 is excellent in field workability. However, in a mode in which the screw head faces downward, the screw may be loosened due to shutter vibration or the like, and eventually fall off. On the other hand, in order to prevent the screws from falling off, if the screws are provided sideways on the side surface of the shutter box or the like, not only will the workability be problematic, but the unevenness of the screw head may affect the appearance. Therefore, there is room for improvement in the shutter box screw fall-off prevention property, on-site workability, and design properties.

  Then, this invention makes it a 1st subject to provide the shutter apparatus which is excellent in on-site workability and can expand a lighting area. A second problem is to provide a shutter device that is excellent in on-site workability and design, and that is less affected by vibration and aging degradation.

  Here, the “screw holding member supported by the fastening piece and provided in the attachment piece” can include, for example, a form in which the screw holding member is placed on the fastening piece and provided in the attachment piece. “Screw is prevented from falling off by a screw holding member” means that, for example, a screw with the screw head down is pinched by the screw holding member or pressed upward so that the screw falls off. It means not being.

  In the present invention, the screw pressing member (32) may have a substantially U-shaped cross-sectional shape, and the screw head of the screw may be disposed inside the U-shape. As a result, the screw head is clamped by the screw pressing member, and the screw can be reliably prevented from falling off.

  On the other hand, in the present invention, the screw pressing member (32) may include an elastic member. As a result, the screw pressing member is securely fixed to the retaining piece, the screw can be pressed, and the screw can be reliably prevented from falling off.

  In the present invention, a box locking piece (31) is provided along the upper edge of the box (300), and a box locking piece (12) is provided above the shutter mounting member. It is preferable that the piece is locked to the locking piece. By locking the locked piece on the upper edge of the box with the box locking piece, it can be temporarily fixed by first locking the upper edge of the box to the mounting part during field construction. Work can be carried out in the state that has been done. Therefore, the box can be safely and easily attached to the attachment member, and a shutter device excellent in workability can be obtained.

  According to the present invention, when the shutter main body is covered with the shutter box, the screw that is screwed so that the screw head faces downward from the lower portion of the shutter box is supported by the screw pressing member. Can be prevented from falling off. Moreover, compared with the case where it screws from the side surface etc. of a shutter box, it is excellent in field construction property. Furthermore, the uneven shape of the screw head is not exposed when the shutter device is viewed from the front. Therefore, it is possible to provide a shutter device that is less affected by aging deterioration and excellent in on-site workability and design.
