Title:
LOUVER DOOR
Document Type and Number:
Japanese Patent JP2015194029
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a louver door that can prevent blades of a blade unit from being curved and deformed toward the outdoor side due to negative pressure.SOLUTION: An internal surface near to an indoor side of a vertical frame 2a (blade unit connection frame material) of a frame body 2 is connected with an external surface near to an indoor side of a vertical attachment 4 (attachment) of a blade unit 3 by using a connection mechanism 6. A projection 40 is provided toward the internal surface of the vertical frame 2a at the internal surface near to the outdoor side of the vertical attachment 4. A gap between the projection 40 and the internal surface of the vertical frame 2a is made smaller than the gap between the internal surface of the vertical frame 2a and the outer side surface of the vertical attachment 4. Thereby, the projection 40 decreases the deformation of the vertical attachment 4, and prevents a blade 5 of the blade unit 3 from being curved and deformed toward the outdoor side due to a negative pressure.
