Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter device provided in a building opening or the like, and more particularly to a shutter device provided in an interior partition opening or the like and capable of emergency opening in a closed state.

[0002]

2. Description of the Related Art As an opening / closing device for an indoor partition opening, a sliding door or a door rotatably supported by a hinge is generally used.

When the sliding door is provided in the opening, a sliding door storage space having a size substantially equal to the opening area is required to store the sliding door when opened, and when the door is provided in the opening, a space where the door can rotate. Need. In particular, a large installation space is required to provide a large opening through which a wheelchair or the like can pass, regardless of whether a sliding door or a door is provided. Therefore, in the case of a general house, it is difficult to provide a partition with an opening / closing device having a large opening.

There is a winding type opening / closing device as an opening / closing device capable of opening / closing a large opening and having a small installation space. For example, it is a shutter device that opens and closes an opening by using a flexible, soft cloth or synthetic resin sheet-like screen as a shutter curtain, and winding or unwinding the shutter curtain on a winding shaft. . In such a shutter device, the space required for installing the storage portion of the shutter curtain is small, and the shutter device can be sufficiently installed in a general house where there is no room in space.

[0005] Further, there are a shutter curtain that is opened and closed electrically or manually. In the case of electrically opening and closing, an opening / closing button is provided at a position close to the opening, and the shutter curtain can be opened / closed by operating the opening / closing button, or the shutter curtain can be opened / closed by an operation from a remote controller. ing.

Further, in the case of manually opening and closing the shutter curtain, the shutter curtain is biased in the opening direction by a balance spring, and when the shutter curtain is pulled down, the shutter curtain is held at an arbitrary position. It has a mechanism. Further, there are some which are manually opened and closed so that they can be locked in a completely closed state.

[0007]

In the above-mentioned winding type shutter device, which is electrically opened and closed, the shutter curtain cannot be opened due to an unexpected situation such as a power failure or a drive circuit failure. In case of emergency opening, there is no means to open and close the shutter curtain manually.Therefore, if the shutter curtain is a sheet-shaped screen, it breaks the screen and enters the room The people in the room were out to the outside.

Even if the shutter curtain is a sheet-shaped screen and is manually operated, if the shutter curtain is locked from the inside, the shutter curtain still has to be broken to enter the room.

As described above, in the conventional shutter device, when the shutter curtain was a sheet-shaped screen, it was possible to enter and exit by breaking the shutter curtain. Replacement work was required. Further, when the shutter curtain is made of a hard material such as metal slats, the shutter curtain itself is sturdy and difficult to break easily, and when the shutter curtain is broken, the guide rail is also damaged. There is a fear that repair work will take a long time.

In view of the above situation, the present invention makes it possible to open and close the opening relatively easily without damaging the shutter device when the shutter curtain cannot be opened by the shutter device. This makes it easy to carry out repair work.

[0011]

According to the present invention, a guide rail unit for guiding a shutter curtain is provided in an opening, and at least one guide rail unit of the guide rail unit is provided facing each other to form a guide groove. The shutter device is provided with a pair of guide rail pieces, the guide rail pieces being separable so as to release the guide state of the shutter curtain and open the guide groove, and the pair of guide rail pieces face each other. And a pair of guide rail pieces facing each other so that at least a part thereof elastically fitted to the projection piece is connected by a connecting member made of a synthetic resin and united. A projecting piece is formed, the projecting pieces facing each other are elastically fitted, and both guide rail pieces are joined together in a shutter device.
