Floor Mounted Strip Curtain Door

A strip curtain door but affixed to the floor and made of semi rigid plastic material resembling a tape measure except clear and scaled up. Under the floor, a mechanism resembling a double row of oversized retractable tape measures supports 2 rows of slightly curved plastic sheets which make up the curtain. When someone approaches the door, a motion sensor cues the door mechanism to rapidly retract, like letting go of a tape measure, and the plastic strips zip down into the floor, neatly coiling. Then a minute or so later the coils would slowly unfurl and re-extend up to block the door.

The benefit is the function of a strip curtain door without the difficulty of pushing through hanging strips of plastic.
