For this reason, in buildings such as condominiums, condominiums, and buildings, where there are few openings in the building, an electric shutter device that cannot manually open the shutter slat in an emergency such as a power failure is installed in order to secure an entrance when a fire occurs. It cannot be done. In other words, according to the Fire Defense Law and the Building Law, it is necessary to open the emergency entrance of 120 cm or more.
It is stipulated that it has no structure that prevents entry.

That is, according to the conventional electric shutter device, there is a problem in that it cannot be installed because it cannot be opened 120 cm or more in an emergency (during a power failure) and has a structure that prevents entry. Therefore, the current situation is that the electric shutter device can be used only in a general detached house.

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

(Means for Solving the Problems) In order to solve the above problems, the shutter opening device of the present invention is provided with a shutter box projecting to the outdoor side above the opening of a building, and an electric motor is provided in the shutter box. Is provided with a shutter core rod for winding the shutter slat, an opening having a width equal to or larger than the width of the shutter slat is provided on the lower surface of the shutter box, and the lid plate is pivotally attached to the opening at one edge side thereof. The lid plate is mounted so that it can be opened and closed freely, and the parts other than the pivotally attached part of the lid plate are fixed by a fixture, and the lid plate is drooped downward by being pushed by the shutter slat that is lifted in an emergency and falls on the lid plate, It is characterized in that a part of the shutter slat is hung from the mouth.

Further, the shutter guides provided on both sides of the opening are fitted with locking catches for locking the locking pieces mounted on the lower part of the shutter slat, and the locking catches move from the outdoor side to the retracted position. By providing an alarm device that has an operating part for causing the locking receiver to emit an alarm when the locking receiver is in the retracted position, by moving the locking receiver to the retracted position in an emergency, the width from the outside can be increased. The shutter slat can be opened by lifting a tree, and in a normal state, the alarm device is activated when the shutter slat is opened from the outside, which can serve as a crime prevention function.

Further, by providing an alarm device that operates when the cover plate is opened, the same crime prevention function as described above can be achieved.
