<p><P>PROBLEM TO BE SOLVED: To provide a louver blade capable of simultaneously checking slipping-out damage of slipping out the louver blade from a holding arm, rainwater infiltration damage of infiltrating rainwater and breaking damage of breaking glass, without arranging a conventional surface lattice having risk of being instantly broken by using a bar and separately installed on the outdoor side. <P>SOLUTION: This louver blade 11 is formed by covering an edge part of plate glass 21 with a metallic frame 22 having a cross section of a groove shape and having a smooth surface. The metallic frame for covering the edge part is provided with a fixing means 30 for fixing the louver blade 11 to a body part 51 of the holding arm 50. Slipping-out from the holding arm is checked by being fixed by the fixing means, and infiltration of rainwater is checked by contact of mutual smooth surfaces of the metallic frame, and braking is checked by forming the surface lattice in the edge part by the metallic frame having the cross section of a groove shape. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
