ABSTRACT:
A portable room divider comprises a plurality of slats (10-13) rotatably disposed between a pair of blocks (14, 15) by threads (19, 20) so as to spread the slats (10-13) away from the block (14) when rotated in one direction and draw the slats (10-13) toward the block 14 when rotated in the other direction, whereby the room divider (10-15) can be wedged between a floor and a ceiling, and thereafter released.
