Description

  The present invention relates to a stringer for a blindfold louver that can be used as a blindfold for windows, or as a fence for a border wall or a veranda of a middle- and high-rise house.

  For the purpose of crime prevention, it is common practice to provide a face grid on the outdoor side of the window. Although this surface lattice is excellent in daylighting and ventilation, it has a high possibility of being infringed on privacy regardless of day or night because of high transparency in the indoor and outdoor directions.

  On the other hand, as described in Patent Document 1, a window louver in which a lattice panel is attached to each of a plurality of locking portions formed at equal intervals in the length direction of a stringer has transparency. Since it is low, it can be effective in preventing privacy infringement and is suitable as a security device for windows.
