The present invention is a system and method for an easy installation storm door for installation in a home. The door system may include a door panel that is mounted onto two vertical z-bar frames such that the door system can be installed in a left hinge or right hinge format. The z-bar frames are precut at the factory to be shorter than a standard doorframe so that they do not have to be cut during installation. Also included in the system are top and bottom expanders that fit onto a top and bottom side of the door panel so as to selectively adjust the vertical height of the door panel. The top and bottom expanders further insure a reasonable air and moisture barrier between the interior and exterior of the home. The door system further includes a lock assembly that is pre-installed such that it can be utilized whether the door system is installed in a left hinge or right hinge format. The lock system may include a lockbody that includes duplicate hardware such that the door panel can be situated in the doorframe in a right hinge or left hinge format without having to adjust the position or orientation of the lockbody.

A window incorporates at least one moving glass insert or sash slidable in first and second spaced apart tracks. An end of the insert or sash is coupled to an end of a spring biased rolled screen. As the insert or sash moves from the roll, the screen is extracted therefrom providing a continuously variable screened region in the window. The insert or sash can be positioned using a counterbalance or spaced apart latchable locations in the window.

The present invention utilizes a vertically upward force of a water when a tsunami smashes into a building to close openings that exist in an elevated location such as air supply and exhaust ducts, powerlessly and without a manual operation. The present invention serves as a disaster prevention panel which closes an opening 2a disposed in a wall of a building 2. A door bumper 3 is disposed on an outer peripheral wall of the opening 2a, and side door bumpers 4 are disposed on both sides of the door bumper 3. A door body 1, which closes the opening 2a and which has a specific gravity lower than a seawater, is attached between the side door bumpers 4 on both sides so as to freely swing upwards, with a lower portion of the door bumper 3 serving as a fulcrum.

A door incorporating at least one movable glass insert or window sash slidably disposed in at least one track thereof. An end of the insert is coupled to an end of a spring biased roll of screen. As the insert moves from the spring biased roll, the screen is extracted therefrom providing a continuously variable screened region in the door. The insert can be positioned using a counterbalance, spaced apart latchable locations in the door, frictional engagement, or through the tension force of the biased roll of screen. A catch mechanism is disposed on the movable glass insert to detachably couple the glass insert to a portion of the door.

A two door system for recreational vehicles or camper style trailers is disclosed including an interior door with a self-closing access panel for reaching a locking mechanism of an exterior door. The access panel provides a user the ability to reach and manipulate the latching mechanism of the exterior door from the interior of the vehicle even when the interior door is closed. A biasing member is disclosed that maintains the access panel in a closed position whenever an adequate opening force is not present. The access panel may take on a number of configurations and may be designed as a retrofit for existing door systems or as an original component. In a configuration, a vertically sliding movable panel portion may be provided, which defaults to a downward, closed position. In such embodiments, no biasing member may be needed (gravity may be sufficient for the movable panel portion to close).
