Abstract
A fully-integrated system for ventilating a structure. System includes a hood, an outlet tube, a flapper, a flange, and an adapter. Adapter allows the system to be integrated into the structure, for instance on a roof. System allows air to flow out of the structure. Flapper lifts with airflow but falls with gravity, providing both an outlet for outflow air and a barrier to inflow air. Flange protects the hole in the structure into which the system is installed, and can be flat, meaning perpendicular to the plane of the length of the tubular member, or at an angle thereto, for installation on flat or angled roofs. Hood provides protection from airborne debris, precipitation, animals, or other objects that may block the system. System may include a flexible membrane that allows integration into different shapes of structures and provides an additional measure of protection to the structure and the system.

The flange is a manner of protecting from outside contaminants the area into which the ventilation system will be inserted, as well as providing stability of the system for ventilating a structure. In the present embodiment, theflange 6 is disposed near theadapter end 3 of thetubular member 1, meaning that the flange is in the lower half of the tubular member, yet not flush with the adapter end of the tubular member. Theflange 6 as depicted is square, but the flange can be any shape, such as a circle, a rectangle, a triangle, etc., without altering the function of the flange. Theflange 6 as depicted is flat, meaning that it is perpendicular to the plane along which the length of thetubular member 1 runs, and parallel to the plane on which the end of the tubular member sits. This is in part what allows the pre-assembled ventilation system of the instant disclosure to be installed in multiple job sites, including sites with flat roofs, further providing the aforementioned benefit over the inadequate, custom-made systems. Theflange 6 could also be at an angle to the plane along the outside surface of thetubular member 1, allowing the system to be installed on angled roofs, such as, for example only, an A-frame roof. Theflange 6 as shown is exemplary and should not be construed as limiting the shape or plane of the flange. - In some embodiments, the system for ventilating a structure may have a
base membrane 7. Thebase membrane 7 is a flexible material disposed over the surface of theflange 6.

Thebase membrane 7 also serves to better integrate the ventilation system into the structure by allowing the membrane to better conform to the shape of the structure. In some embodiments, thebase membrane 7 may provide insulation to the system for ventilating a structure. In one embodiment, thebase membrane 7 may be disposed directly on the surface of theflange 6. In some embodiments, thebase membrane 7 may be over theflange 6 but not in direct contact with the flange. In the present embodiment, thebase membrane 7 is shown as square so as to conform to the shape of theflange 6. However, thebase membrane 7 may be any shape, and that shape may or may not conform to the shape of theflange 6, neither of which would alter the function of the membrane. In the present embodiment, thebase membrane 7 is larger than theflange 6. In some embodiments, thebase membrane 7 may be the same size as theflange 6. In some embodiments, thebase membrane 7 may be slightly larger than theflange 6. In other embodiments, thebase membrane 7 may be significantly larger than theflange 6. - The system for ventilating a structure may, in some embodiments, have a
tubular membrane 8. Thetubular membrane 8 is a material disposed around thetubular member 1. In some embodiments, thetubular membrane 8 may be a flexible material.
