ABSTRACT:
A closure apparatus for closing an opening in a partition with a frame disposed around the opening includes a drum member rotatably mounted to the partition at the top end of the opening. It also includes a curtain member secured to the drum member. The curtain member winds around the drum member to move out of the opening in the partition; and it extends from the drum member to close the opening. A counterweight connected to the drum member offsets the weight of the curtain member; and a reducing weight reduces the weight of the counterweight to allow the curtain member to drop from a raised position. An activating assembly engages the reducing weight with the counterweight and allows the curtain member to unwind from the drum member and close the opening.
