I could do this and just not tell her about it
I think it's a great idea for a bedroom too.
The advantage that fixed frames have over retractable is that they don't get waves, wrinkles, or curled edges.
Tab tension screens are an expensive and not really a DIY solution if you want the smallest profile for the stored screen. Nothing beats rolling a fabric for small-profile.
But ... what if you didn't need the absolutely smallest profile ?
Imagine an accordion folding screen consisting of 8 fixed frames, each 12" high and 12 feet wide made from 1x2 wood with vertical supports. They would be piano hinged to each other. Then stretch white spandex like this over the entire 8 foot x 12 foot assemblage. http://www.spandexhouse.com/products...id%20Colors%29
Note that it would only take $36 of white spandex.
The spandex would be stretched when stapled to the sides of each frame, but not too close to where it meets the next frame. It would be pulled tight and stapled to the top edge of the top frame and to the bottom edge of the bottom frame, but none of the other frames. When collapsed those little sections of spandex adjacent to the hinges would have to stretch a bit more. When expanded, the spandex shouldn't show any wrinkles or creases because it is stretched tight vertically and stretched spandex doesn't wrinkle. As a bonus, spandex is acoustically transparent so your speakers behind the screen are fine.
Support by hooks on the upper corners and the weight of the screen would hold it straight. The entire assemblage would be about 8 inches tall and 12 inches deep and 12 feet wide when sitting on the floor in front of your entertainment center.
What do you think ? Would the stretchiness of spandex and the fixed frames result in a wrinkle, curl, wave, and crease free screen after years of opening and closing ?
For raising and lowering, think about a nut riding on a threaded rod turned by a motor. Attached to the nut, an 9' diagonal cross piece that attaches to the upper frame via a pivot 4 feet from the side. When in the lowered position, the bottom end of the cross piece attached to the nut would be almost all the way to the end of the threaded rod, but when fully up, the nut would have been pulled 4 feet toward the center.
I think this method of raising and lowering a screen would work for a rolled fabric screen as well, but having the accordion frames holding everything square would be certain. With a rolled screen, what would keep the top level ? Maybe second diagonal running from the other side ? That scissor device shown above would definitely work for the accordion screen.
