Claim 0:
1. An insulated glazing unit, comprising:
a frame comprising a base, a cross member above the base, and two upright members for connection between the cross member and the base;
at least two at least partially transparent panes that are applied to the frame, wherein the at least two at least partially transparent panes and the frame define a closed volume;
a light ray shielding device within the closed volume;
support means mechanically connected to the cross member and operably associated with the light ray shielding device in supporting relationship thereto;
wherein the light ray shielding device comprises a plurality of slats and a bottom member, wherein the slats are connected to each other and to the bottom member, wherein the light ray shielding device is configured to alternate between a raised position, in which the slats and the bottom member are compacted together, and a deployed position, in which the bottom member is proximate to the base;
first stationary guide means at the base of the frame; and
second moving guide means on the bottom member of the light ray shielding device;
wherein the bottom member is configured to alternate between a first configuration, in which the bottom member is able to slide toward/away from the base thereby defining a slide direction, and a second configuration, in which the bottom member is proximate to the base and is tilted to the slide direction, and
wherein the first stationary guide means and the second moving guide means are configured to contact each other when the light ray shielding device is in the deployed position and to alternate the bottom member from the first configuration to the second configuration.
