Window shutter

A shutter for application to a window comprising a plurality of horizontal slats mounted in vertically-spaced relation and movable either to a lowered operative position with respect to the window, or to a raised position overlying the window, tilting means for simultaneously tilting all said slats about their horizontal axes from horizontal positions to vertical positions when the slats are in their lowered operative positions with respect to the window, and raising means for raising the slats from their lowered operative positions to raised horizontal positions with respect to the window;

• said plurality of slats being mounted on shafts received within channels located at opposite sides of the window and guiding the movement of the shafts of the slats when the slats are tilted, raised and lowered;
• and tilting means comprising a U-shaped profile member extending vertically within at least one of the channels and coupled to the ends of said slats, said U-shaped profile member being supported by a parallel-link mechanism such that movement of the U-shaped profile member horizontally in one direction pivots the slats to their horizontal positions, and pivoting the U-shaped profile member horizontally in the opposite direction pivots the slats to their vertical positions.
