Definitions

  • the present disclosure relates generally to a roof vent for venting the roof of a building such as a house.
  • Roof vents provide the necessary ventilation to the roof of a house or other building, inhibiting condensation in the roof from the infiltration or collection of moisture into the roof or attic cavity.
  • Various roof vents employ vanes, grates and louvers to permit atmosphere to be channeled between the roof and the atmosphere and to try to inhibit rain and snow from entering the roof through the roof vent.
  • a variety of caps and covers have been used to act as a guard to prevent the infiltration of rain and snow.
  • roof vents typically include a horizontal top edge that provides an area for precipitation to accumulate when the roof vent is placed on a sloped roof. If precipitation is allowed to build up on a top edge of a roof vent, moisture can creep under the roof shingles and potentially damage the roof structure. For example, water can damage the plywood under the shingles causing rot which may lead to leakage and damage to other aspects of the building. Accumulation of snow at the top edge of a roof vent can also create an area of increased loading on a roof surface.
  • An improved roof vent for ventilating a sloped roof of a building via a hole in the roof to atmosphere but inhibits the infiltration of precipitation is desired.
  • a top edge of a roof vent such as this may act as an atmospherefoil leading edge capable of changing the direction of atmosphere flow as atmosphere travels down the surface of a roof. This change of direction inhibits the stagnation of atmosphere and atmosphereborne particulates such as rain or snow at the top edge of the roof vent.
  • FIG. 1 is a perspective view of a roof vent.
  • FIG. 2 is a perspective view of a preferred embodiment of the roof vent with cap attached.
  • FIG. 3 is a perspective view of the roof vent shown in FIG. 1 without the cap attached.
  • FIG. 4 is a cross-sectional view of the roof vent shown in FIG. 1 .
  • FIG. 5 is a perspective view of the roof vent shown in FIG. 1 .
  • FIGS. 6A , 6 B, 6 C and 6 D are perspective views of alternate embodiments of the roof vent shown in FIG. 1 .
  • FIG. 1 shows an improved roof vent 10 which provides for roof ventilation while at the same time inhibiting the infiltration of precipitation including rain, snow or other atmospheric particles into an attic.
  • Roof vent 10 is comprised of a flange portion 12 , a wall surface 11 and a cap 16 .
  • Flange portion 12 is intended to affix to roof 50 and is preferably flat to rest flush with roof 50 and to provide for easy installation of roof vent 10 .
  • Wall surface 11 extends upward (e.g. perpendicularly) from flange portion 12 and about a periphery of opening 22 .
  • the cap 16 is dimensioned to cover over wall surface 11 and hole 28 but is also configured to provide for a gap 18 between cap 16 and flange portion 12 to permit atmospheric atmosphere to pass between the wall surface 11 and cap 16 .
  • Cap 16 also has a curvilinear first face 62 to deflect precipitation travelling along roof 50 away from a hole 28 in the roof 50 .
  • the roof vent 10 provides for roof ventilation while at the same time inhibiting the infiltration of rain, snow and other undesired atmosphere particulates.
  • Flange portion 12 is preferably flat to rest against the surface of the roof 50 and cover over at least a portion of the surface of the roof 50 .
  • Flange portion 12 has a top surface 13 and an opening 22 to communicate with a hole 28 in roof 50 .
  • Wall surface 11 has a central cavity 26 which communicates with opening 22 to permit atmosphere to circulate between attic interior 30 , through hole 28 in roof 50 and cavity 26 of the wall surface 11 .
  • Wall surface 11 has one or more apertures 24 through which atmosphere can circulate between cavity 26 and outside atmosphere 32 through atmosphere passage 20 and a gap 18 , where gap 18 is between the flange portion 12 and the cap 16 .
  • wall surface 11 is formed as a frame having upper portion 38 , lower portion 40 and sides 36 formed from support members 14 . Apertures 24 is formed in wall surface 11 to alow for the passage of atmosphere between the atmosphere 32 and the cavity 26 .
  • the wall surface 11 is one example of a frame that can provide for structural rigidity between the cap 16 and flange portion 12 , thus providing for structural integrity of the roof vent 10 in keeping the cap 16 at a spaced apart distance from the flange portion 12 .
  • Wall surface 11 can extend transversely (eg. perpendicular) to opening 22 .
  • Cap 16 can be dimensioned to cover over opening 22 from above.
  • An atmosphere passage 20 can be formed between cap 16 and wall surface 11 so that atmospheric particles can flow through a side wall of wall surface 11 and atmosphere passage 20 and out gap 18 . Any wind driven precipitation or other undesired particulates can be deflected by the wall surface 11 and cap 16 and thus be inhibited from entering the hole 28 and the attic space 30 . Since atmosphere passage 20 can be larger than gap 18 , a quantity of precipitation in the atmosphere can be deflected by the outside of wall surface 11 and not inhibit the flow of atmosphere outside of the roof vent 10 and attic interior 30 .
  • cap 16 has a first face 62 directed towards a peak of roof 50 , a second face 63 opposite the first face 62 and two opposing side faces 64 and 66 connecting the first face 62 to the second face 63 .
  • the cap 16 also has a cover surface 17 between opposing faces 64 and 66 that connects all four side faces 62 , 63 , 64 and 66 .
  • First face 62 connects to each of the opposing side faces 64 and 66 at two corners 81 and 82 of cap 16 .
  • Second face 63 connects to each of the opposing faces 64 and 66 at two different corners 83 and 84 of cap 16 .
  • FIG. 6A illustrates one embodiment of cap 16 where faces 62 , 63 , 64 and 66 are connected to each other at corners 81 , 82 , 83 and 84 , where the corners 81 , 82 , 83 , 84 are regions of intersection of the faces 62 , 63 , 64 and 66 .
  • Cap 16 is circular in shape.
  • first face 62 refers to the face of the circle shaped cap 16 substantially facing the peak of roof 50 .
  • Second face 63 refers to the opposite face of cap 16 substantially opposite to the first face 62 and facing away from the peak of the roof.
  • Opposing faces 64 and 66 refer to the two portions of the circular shape connecting the first face 62 to the second face 63 .
  • the cap 16 can be supported by either of a plurality of separate support members 14 or by support members incorporated into the wall structure 11 .
  • the cap is dimensioned to cover over the wall surface 11 and the opening 22 while providing a gap 18 between the flange portion 12 and the cap 16 .
  • Gap 18 is illustrated in FIG. 4 and provides for the passage of atmosphere between the wall surface 11 and the cap 16 .
  • First face 62 of cap 16 extends towards roof 50 to overlap with at least a portion of wall surface 11 at overlap region 71 (see FIG. 2 and FIG. 4 ).
  • First face 62 provides a surface to inhibit the movement of precipitation from contacting the wall surface 11 and from entering the interior attic space 30 through the hole 28 in the roof 50 .
  • First face 62 provides a surface connecting the two opposing side faces 64 and 66 , first face 62 also extending laterally from the second face 63 towards a peak of roof 50 .
  • a middle point of the first face 62 is laterally closer to the peak of the roof than the two opposing side faces.
  • first face 62 is shaped to direct and deflect precipitation moving towards the first face 62 towards the two opposing side faces 64 and 66 of the cap 16 .
  • first face 62 can dictate the direction in which precipitation is directed as it moves down the surface of roof 50 towards first face 62 .
  • First face 62 directs precipitation away from a midline X of roof vent 10 as shown in FIG. 5 .
  • Precipitation, including rain, snow and other undesirable atmospheric particulates, can also be directed in a direction opposite to that of the surface of roof 50 and over cap 16 .
  • first face 62 is arcuately shaped over all or a portion of its surface which connects the two opposing faces 64 and 66 , where arcuately shaped is any shape that is curvilinear and curvilinear shapes are such that consist of a curved line or lines.
