Abstract:
1. A multi-level window shutter having a shutter frame movably supporting at least one first level external shutter panel between an external closed position and an external open position and an external panel opening mechanism mounted on the shutter frame and connected to the external panel for selective displacement thereof relative to the shutter frame, the window shutter comprising: at least one second revel internal shutter panel movably, directly and entirely supported by the external shutter panel between an internal closed position with the external and internal panels being substantially in a generally side-by-side configuration relative to one another in spaced apart parallel planes with the external panel being in the external closed position and an internal open position with the external and internal panels being in a generally over-one-another configuration relative to one another in the spaced apart parallel planes with the external panel being in the external open position; and an internal panel opening mechanism mounted on the shutter frame and connected to the external panel and to the internal panel for simultaneous displacement of the internal panel upon displacement of the external panel relative to the shutter frame, the internal panel opening mechanism being physically independent from the external panel opening mechanism and being activated by the external panel upon displacement thereof relative to the shutter frame; the external panel includes an external panel frame having a frame extension for supporting the internal panel when in the internal closed position, the frame extension extending generally internally away at least from an upper section of the external panel frame in the plane of the external panel, the frame extension extending over a length substantially equal to a width of the internal panel so as to support the internal panel over its entire width when in the internal closed position.
