INTERIOR SHUTTER-BLIND FOR WINDOWS WITH STACKABLE LOUVERS

摘要

A shutter-blind system for windows is provided. The system includes a plurality of rotatable parallel louvers. Each louver is rotatable about an axis offset from its center of gravity. The system further includes a resisting member coupled to a louver located at a lower end of the plurality of louvers, the center of gravity of the louvers with the offset axis pulling against the resisting member to maintain tension in the collapsible linkages. All of the louvers of the plurality of louvers are rotated in a substantially matched rotation in response to rotation of the lower louver. All of the louvers are held in position in response to the force of gravity on the offset louvers acting against the resisting member.

1. A shutter-blind system for windows, the system comprising:
a frame assembly; a plurality of rotatable parallel louvers coupled within the frame assembly, each louver of the plurality of louvers operatively coupled to adjacent louvers with a collapsible linkage; each louver rotatable about an axis offset from its center of gravity; and a resisting member coupled to a louver located at a lower end of the plurality of louvers, the center of gravity of the louvers with the offset axis pulling against the resisting member to maintain tension in the collapsible linkages, wherein:
all of the louvers of the plurality of louvers are rotated in a substantially matched rotation in response to rotation of the lower louver; andall of the louvers are held in position in response to the force of gravity on the offset louvers acting against the resisting member.
