Abstract
A modular louver system is disclosed which utilizes a series of joined frames having the same basic cross section, a series of spacers, and a series of louver vanes having the same v shaped cross section. The frames have a t-shaped channel, with inwardly facing channel lips defining the narrow portion of the t-shaped channel. The louver vanes have a dovetail at each end, where the dovetail neck will fit in the area defined by the inwardly facing channel lips. In addition, the spacers are shaped so that they will rest in the t-shaped channel and will either separate the louver vanes from each other or from an adjacent frame. The louver vane dovetails are inserted in the t-shaped channels of opposing frames, with at least one spacer inserted in the t-shaped channels to separate the louver vanes from each other and from an adjacent frame. Where rectangular connection is desired, the frames are connected either using a clip joint arrangement. Where the modular louver system uses rounded corners, a corner frame is used to allow for a rounded edge.
