second embodiment

[0070]FIG. 8 is a pictorial view of a flat roof vent assembly 110. As may be seen, this second embodiment does not include an external baffle such as 34 in the previous embodiment. Instead, the cowl 120 extends all the way towards its foot end so that it is substantially flush with the foot end of the base 130. This provides an aesthetically pleasing image. The cowl 120 can be attached to the base in the same manner as in the previous embodiment.

[0071]FIG. 9 is an exploded view of that shown in FIG. 8, showing some components thereof, namely the cowl 120 and the base 130. 134 is a large internal baffle, 135 is a first small internal baffle, and 136 is a second small internal baffle. As may be seen in this case, all three of the baffles are covered by the cowl. However, the relative shapes of the three baffles 134, 135, and 136 are similar to those of the previously discussed baffles 34, 35, and 36.

third embodiment

[0072]FIG. 10 is a pictorial view of a flat roof vent assembly 210. This assembly 210 includes a cowl 220 and a base 230. The assembly 210 also includes a cowl retention member not shown in this figure but illustrated later as 240 in FIG. 13.

[0073] The base 230 includes a floor plate 231 (which defines a lower major planar portion), a raised shelf 233 (which defines an upper major planar portion), and a front external baffle 234. The base also includes nailing locations 239 to receive nails for fastening the base to a supporting roof structure.

[0074] The cowl 220 includes downwardly oriented standoff feet 225 which bias on the top surface of the floor plate 231.

[0075]FIG. 11 is an isolated pictorial view of the base 230 of FIG. 10. It may be seen that there is an upturned peripheral wall 236 extending around the “quasi-pentagon” vent opening 232, which is defined by the base. The upturned wall 232 is configured to reduce the opportunity for water to pass therethrough; instead the ...

first embodiment

[0101] It should be understood that although certain combinations of internal and external baffles have been shown for purposes of indication, it should be understood that there are other alternative configurations that still manage to be covered by the present invention. For example, instead of using two small internal baffles, three or one internal baffles could be used; in fact, any reasonable number of internal baffles could be used within engineering limitations. At the same time, a large external baffle could be used as shown in the first embodiment, with the large external baffle having various height possibilities, depending on the severity of the weather of the application. Furthermore, the embodiments shown above discuss baffles with a vertical orientation. It should be noted that this is just one embodiment and in fact a horizontal labyrinth is also envisioned for the same purpose. Furthermore it could also be said that air passes “through” the labyrinth as opposed to “ov...

Abstract

A roof vent construction which is comprised of an assembly including a cowl, a base, and a cowl retaining member. These elements provide a structure which provides cover for rain and discourages rain from entering the vent underneath the cowl, but nevertheless allows for suitable ventilation as needed. In one embodiment a configuration is used in which an external baffle is used which air passes before passing underneath a cowl. Once the air is passed underneath the cowl, the air then passes over one and one configuration two internal baffles before the air passes out of a pair of vent cavities defined by the base. In a second configuration, a cowl extends substantially to the leading edge of the construction. Air flows underneath the leading edge of the cowl and then passes over a large internal baffle, over a first small internal baffle, and finally over a second small internal baffle before passing through the vent cavities and out of the structure. Another invention relates to the use of two surface portions on the vent assembly, one surface portion configured to match a first course of tiles and the other surface portion configured to match a second course of tiles adjacent to said first course of tiles.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application claims the full benefit and priority of pending provisional application No. 60 / 491,405, filed, Jul. 31, 2003, entitled “Roof Vent Having Labyrinth Features”. The entire contents of this provisional application are likewise incorporated by reference.BACKGROUND OF THE INVENTION [0002] In the construction of roofing, it is known to provide roofs made of individual roofing elements. The elements can be flexible, such as asphalt shingles, or rigid, such as clay or concrete tiles. [0003] It is also known to provide vents in the roofing structure to provide roof ventilation. However, providing such venting can introduce problems relating to the prevention of water being drawn in along with the ventilating air flow. Therefore there is a need in the art to provide an improvement of such vents. BRIEF SUMMARY OF THE INVENTION [0004] The present invention provides in improvement of over the art by providing an improved roof vent tha...
