Description

ANTI BANDIT SHUTTER}

The present invention relates to a multidirectional bending security shutter, and more particularly, to a multidirectional bending security shutter, and more particularly, to a multidirectional bending security shutter having a curved surface formed in a building structure or an internal structure provided in a bending structure, The present invention relates to a multidirectional curved security shutter capable of being installed.

In general, a shutter means an auxiliary iron door installed to perform a crime prevention function on an entrance door of various buildings such as a commercial building. Such a shutter is a horizontal door with a tubular structure having a predetermined length and having a foldable tubular structure, It rolls up in the form of a scroll in the upper axis and closes. The conventional shutter used for such a purpose is locked and unlocked by a lock bundle installed on the lower side of the shutter. In order to enter the building, the lock is unlocked and the shutter is manually lifted, or as shown in FIG. 7 , And an automatic shutter system in which the shutter is lifted by a rotating means driven by a switch operation.

The automatic shutter includes a plurality of cross members that are foldably installed, one end of which is connected to a rotation shaft inside the shutter box, and a rotating means for rotating the rotation shaft. In addition, a shutter guide plate is further provided inside the shutter box so that the cross bar is smoothly rotated and folded.

However, the conventional security shutter has a horizontally formed structure, and in the case of a curved surface, it is difficult to install a security shutter, so that an intruder can easily enter the security shutter.

In addition, since a plurality of shutters are connected to install the curved surface structure, there is a problem in that the cost increases because the structure is changed or the facility is added.
