Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a device for opening shutter slats in an emergency in an electric shutter device equipped with an electric motor as an opening/closing drive device, and particularly relates to a device for opening shutter slats in an emergency. The present invention relates to an opening device having a manual opening means suitable for installing an electric shutter device in.

(Prior Art) Electric shutter devices can be opened and closed by operating a switch, and therefore have the advantage that they can be opened and closed easily without requiring any effort compared to manual shutter devices.

(Problem to be solved by the invention) However, in general, electric shutter devices cannot open the shutter slats manually. Therefore, in buildings with few openings, such as condominiums, apartment complexes, or buildings, fires may occur. In order to secure an entrance at times, electric shutter devices cannot be installed in which the shutter slats cannot be opened manually in the event of an emergency such as a power outage. That is, the Fire Service Act and the Building Act stipulate that an emergency entrance must be open at least 120 cm and must not have any structure that obstructs entry.

That is, the conventional electric shutter device cannot be opened beyond 120 cm in an emergency (during a power outage) and cannot be installed because it has a structure that prevents entry. Therefore, the current situation is that electric shutter devices can only be used in ordinary detached houses.

An object of the present invention is to realize a shutter opening device for realizing an electric shutter device that can be installed in an apartment, a housing complex, or a building.

(Means for Solving the Problem) In order to solve the problem described in 1-, the shutter opening device of the present invention includes a shutter box that is provided at the top of the opening of the building and projects to the outdoors, and that A shutter core rod rotated by an electric motor to wind up the shutter slats is provided, and an opening having a width equal to the width of the shutter slats is provided on the lower surface of the shutter box.
A lid plate is attached to the opening so that it can be opened and closed by pivotally connecting one edge thereof, and the portion of the lid plate other than the pivoting part is fixed with a fixture, so that the lid can be lifted in an emergency. The cover plate hangs downward by being pushed by the shutter slats falling on the plate,
It is characterized by having a structure in which a part of the shutter slat hangs down from the opening [1].

In addition, locking holders for locking the locking pieces attached to the lower part of the shutter slat are attached to the shutter guides provided on both sides of the opening, and the first latching holder is moved from the outdoor side to the retracted position. By having an alarm device that has a movable operation part and issues an alarm when the locking bracket is in the retracted position, in an emergency, by moving the locking bracket to the retracted position, the locking bracket can be moved from the outside. The shutter slats can be opened by lifting the baseboard, and in normal times, when the shutter slats are opened from the outside, an alarm system is activated, thereby serving as a security measure.

Furthermore, by providing an alarm device that is activated when the lid plate is opened, the same crime prevention role as described above can be achieved.

(Example) An embodiment of the present invention will be described below with reference to the drawings.
