An Adjustable flood-resistant barrier for removable installation in a window or door opening or the like. A laterally adjustable frame is received within an elastic envelope and can be laterally expanded to engage the sides and bottom of the opening. An adjusting mechanism includes a shaft, which projects upward above the top of the frame, approximately in the center thereof, and mounts a handle for both carrying the panel and rotating the shaft to effect width adjustments of the panel. An improved peripheral seal minimizes the likelihood of leakage at the corners. For wide openings, mullions are provided to support central areas and to increase downward sealing pressures in the center of the panel. Mullions can also be positioned between an opposed pair of barrier panels for closing off unusually wide openings.

The object of the present invention is to prevent an overflow of water into living spaces and underground spaces, to prevent difficulties in lower the door body when the water level has dropped, and to prevent the door body from suddenly falling. This is achieved by a floating flap gate 11 which is disposed at an opening or at an access way, so as to block the opening or the access way when water w flows in, and comprises a door body 12 with a forward end which is able to swing upwards, within in a plane in a height direction in a direction in which the water flows in around a base end thereof serving as a fulcrum. A rod 13 is attached to the forward end of the door body 12. One end of a wire rope 14 is attached to the rod 13, and the other end is attached to a counterweight 20 via fixed pulleys 16, 17. The fixed pulley 16 is arranged so that the counterweight 20 is at its lowest point when the angle of inclination of the door body 12 with respect to a horizontal plane reaches within a range from 10° to 80° during raising or lowering of the door body 12.

The flood vent has an elongated box-shaped frame having a top end, a bottom end including a floor, and opposing sidewalls that define a fluid passageway. The frame has an open front and a track formed in the rear of the frame. A door is slidably mounted in the track so that a normally closed position blocks the fluid passageway. The door is sufficiently buoyant to permit floodwater to float the door in the track and, thus, to automatically vent excess water through the fluid passageway. Installed in a crawl space, basement, or similar structure, the venting action of the flood vent limits hydrostatic pressure buildup against the walls of the structure when floodwaters rise, thus preventing structural damage from occurring.
