Framed covering for architectural opening
A framed covering for an architectural opening includes a collapsible shade that is moveable between open and closed positions relative to the architectural opening with the collapsible shade being mounted within an enclosed framework that is adapted to be secured to a structural member having the architectural opening therein. In one embodiment of a flexible control cord system moves the shade between open and closed positions, with the control cord system being conveniently positioned adjacent the frame for easy manipulation. In a second embodiment a finger slide on the frame drives a cord lift system for moving the covering between open and closed positions.
1. An architectural unit comprising in combination:
a peripheral frame having a passage;
a single light transmitting panel mounted in said frame;
a collapsible covering system including a curtain connected to and supported within said peripheral frame, said collapsible covering system further including a control system for moving the curtain between open and closed positions with a portion of said control system extending through said frame for hand manipulation by an operator of the control system wherein said control system further includes at least one lift cord operatively connected to said curtain, at least one rotatable spool connected to said lift cord and around which said lift cord can be wrapped, a drive system for rotating said spool, and a housing surrounding said spool in closely spaced relationship therewith so as to permit said lift cord to be wrapped around said spool in only a single layer; and
connection means adapted to connect said peripheral frame to other objects.
2. The combination of claim 1 wherein said spool has a smooth surface around which said lift cord can be wrapped.
3. The combination of claim 1 wherein said spool has a helical groove in which said lift cord can be confined while wrapped around said spool.
4. The combination of claim 2 wherein said spool is axially moveable to permit a single layer wrap of said lift cord when said spool is rotated.
5. The combination of claim 4 further including resilient means for yieldingly resisting axial movement of said spool.
6. The combination of claim 4 wherein said spool is axially moved as said cord is wrapped on or unwrapped from said spool.
