Abstract
A movable louver window has a frame body and a plurality of double-vane assemblies each having first and second louver vanes and a pair of left and right coupling members. Each pair of left and right coupling members couples said first and second louver vanes. A plurality of double-vane assemblies are mounted within the frame body. Air-tight and water-tight sealing between the frame body and the double-vane assemblies is established by seal members which are provided over the entire circumference of the frame body and continuously connected with each other.

A movable louver window comprising:
- a quadrilateral frame body having an upper frame member, a lower frame member and left and right vertical frame members;
- a plurality of double-vane assemblies each comprising first and second louver vanes and a pair of left and right coupling members each having a pivoting arm, said pair of left and right coupling members coupling to said first and second louver vanes in such manner that an upper portion of said first louver vane extends upwardly beyond an upper portion of said second louver vane and a lower portion of said second louver vane extends downwardly beyond a lower portion of said first louver vane and that said first and second louver vanes are parallel to each other and having a space therebetween, said plurality of double-vane assemblies vertically and pivotably mounted within said frame body and in such manner that when the movable louver window is closed, a lower portion of an upper one of each two vertically adjacent first louver vanes overlaps an upper portion of a lower one of each two vertically adjacent first louver vanes for forming a first continuous wall of louver vanes and a lower portion of an upper one of each two vertically adjacent second louver vanes overlaps an upper portion of a lower one of each two vertically adjacent second louver vanes for forming a second continuous wall of louver vanes, and that between said first and second continuous walls of louver vanes is defined a vertically continuous space for forming a heat insulating air layer therein;
- sealing means for sealing between said frame body and said plurality of double-vane assemblies over the entire circumference of said frame body, said sealing means including an upper horizontal seal member mounted on said upper frame member and directed toward the interior side and being in contact with an uppermost one of said plurality of double-vane assemblies, at least one lower horizontal seal member mounted on said lower frame member and directed toward the exterior side and being in contact with an interior side surface of a lower portion of a lowermost one of said plurality of double-vane assemblies, vertical seal members mounted on said left and right vertical frame members and directed towards the inside of said frame body and each being in contact with side surfaces of said plurality of double-vane assemblies, each of said left and right vertical seal members being connected continuously with said upper horizontal seal member and with said at least one lower horizontal seal member.
A movable louver window comprising:
- a quadrilateral frame body having an upper frame member, a lower frame member and left and right vertical frame members;
- a plurality of double-vane assemblies each comprising first and second louver vanes and a pair of left and right coupling members each having a pivoting arm, said pair of left and right coupling members coupling said first and second louver vanes such that an upper portion of said first louver vane extends upwardly beyond an upper portion of said second louver vane and a lower portion of said second louver vane extends downwardly beyond a lower portion of said first louver vane and that said first and second louver vanes are parallel to each other having a space therebetween, said plurality of double-vane assemblies being mounted within said frame body in vertically pivotable fashion such that when the movable louver window is closed, a lower portion of an upper one of each two vertically adjacent first louver vanes overlaps an upper portion of a lower one of each two vertically adjacent first louver vanes for forming a first continuous wall of louver vanes and a lower portion of an upper one of each two vertically adjacent second louver vanes overlaps an upper portion of a lower one of each two vertically adjacent second louver vanes for forming a second continuous wall of louver vanes and that between said first and second continuous walls of louver vanes is defined a vertically continuous space for forming a heat insulating air layer therein;
- wherein a pivoting center of each of said double-vane assemblies is positioned on the interior side relative to a first louver vane, and positional relationship between vertically adjacent double-vane assemblies is determined to satisfy:
- l.sub.2 <l.sub.2 +l.sub.1 and .theta..sub.2 >.theta..sub.1
- wherein
- l.sub.1 is a distance from a pivoting center of an upper double-vane assembly to a lowermost end edge on the interior side of the first louver vane of the upper double-vane assembly;
- l.sub.2 is a distance from a pivoting center of a vertically adjacent lower double-vane assembly to an uppermost end edge on the exterior side of the second louver vane of the lower double-vane assembly;
- l.sub.3 is a distance between the pivoting centers of the vertically adjacent upper and lower double-vane assemblies;
- .theta..sub.1 is an angle defined by a line extending through an intersecting point of a circle c.sub.1 centered at the pivoting center of the upper double-vane assembly and having a radius of l.sub.1 and a circle c.sub.2 centered at the pivoting center of the lower double-vane assembly and having a radius of l.sub.2 and the pivoting center of the upper double-vane assembly and a line extending through the lowermost end edge on the interior side of the first louver vane of the upper double-vane assembly;
- and
- .theta..sub.2 is an angle defined by a line extending through the intersecting point of the circles c.sub.1 and c.sub.2 and the pivoting center of the lower double-vane assembly and a line extending through the uppermost end edge on the exterior side of the second louver vane of the lower double-vane assembly and the pivoting center of the lower double-vane assembly.
