Benefits of technology

[0011]The blocking member can be an intumescent tape (e.g., 3M™ Expantrol™ Fire Barrier Flexible Intumescent Strip or other commercially available intumescent tapes) or a block of intumescent material. As discussed above, it is contemplated that the blocking member at least partially blocks the flow of material between the inlet and outlet. In some embodiments, a second blocking member having an intumescent material can be disposed on the guiding member. It is contemplated that the blocking member and the second blocking member are configured to collectively block the flow of material between the inlet and the outlet when in the expanded state. A grid can extend across the outlet as an additional safety measure against external materials (e.g., embers, debris, etc.) from entering the structure or building.
[0012]Preferably, the internal passage between the inlet and outlet is non-linear. For example, a first leg member can extend from a surface on the inlet side toward the outlet side, and a second leg member extends from a guiding member in the internal passage toward the inlet side, such that the first leg member and the second leg member direct the flow of ma

Problems solved by technology

Conventional air vents allow the free movement of air in and out of enclosed structures, but typically will not stop the penetration of liquids or solids from getting through vent openings.
Since such intumescent material requires time fo

Example

[0027]The following discussion provides example embodiments of the inventive subject matter. Although each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed.

[0028]Also, as used herein, and unless the context dictates otherwise, the term “coupled to” is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms “coupled to” and “coupled with” are used synonymously.

[0029]The inventors have discovered an effective and economical vent structure th

Abstract

A vent apparatus that prevents the ingress of flames, superheated air, and/or flaming materials (e.g., embers) from an external fire to a building or structure is disclosed. The vent apparatus comprises a frame that defines an inlet, and outlet, and an internal passage. A guiding member is disposed within the internal passage to thereby deflect or direct a portion of a flow of material between the inlet and outlet. A blocking element is disposed on the guiding member that is configured to expand to at least partially block the flow of material between the inlet and outlet.
