LOUVER

PROBLEM TO BE SOLVED: To provide a louver which reduces the amount of rainwater flowing into an indoor even upon strong wind and heavy rain. SOLUTION: The louver comprises a frame body 1, a plurality of louver blades 2 fitted to the frame body 1, and a circulation space 3 formed between the adjacent louver blades 2 so that the outside air may flow from the exterior to the interior. A rainwater receiving part 2a and an intermediate part gutter 2b are formed in a width-wise intermediate part of each of the louver blades 2. Part of the rainwater flowing into the circulation space 3 together with the outside air hits the rainwater receiving part 2a and is immediately collected in the intermediate part gutter 2b. Therefore, the rainwater is not blown up by the strong wind and heavy rain, and the rainwater collected in the intermediate part gutter 2b is discharged along the frame body 1. Thus, the amount of rainwater flowing into the interior is reduced even upon a strong wind and heavy rain. COPYRIGHT: (C)2006,JPO&NCIPI
