Device for retaining edges of window blind

摘要

The blind consists of support (1) adapted to be fixed on a front wall (4) of a channel (13) of a frame (5). A pair of frames house a blind (3), in particular the first and second edges (6,7) of the blind. The support also supports an engaging lever arm (25) for the edges of the blind. The lever arm is supported on an inner surface (17) of the channel. The support further supports a stopping lever (2) for the blind.
