Open-close surface lattice

Abstract

Abstract PURPOSE: To improve appearance by pivoting one end of a large number of grille devices with a common shaft, fixing them freely rotatably on an arbitrary side of a window opening frame and providing a freely-releasable angle restricting device between the respective grille devices. CONSTITUTION: Through holes of a large number of grille devices 2 are aligned so as to superpose end parts with each other, and a common shaft 3 is inserted into the superposed through holes so as to pivot them freely rotatably and is fixed freely rotatably on outer side parts of the grille devices 2. An angle restricting device 10 comprising an arc-shaped member is provided with a grid device fitting groove mated with a disposition angle of the grille device 2. The angle restricting device 10 is mounted by fitting the fitting groove from a rear face side between the two grille devices 2 and is fastened on the grille device 2 by two screws.
