DISCLOSURE OF THE ILLUSTRATIVE EMBODIMENT

(30) A perspective view of an illustrative embodiment of ridge vent 2, according to the present disclosure, attached to a roof 4, is shown in FIG. 1. For illustrative purposes, ridge vent 2 is shown folded over a roof peak 6 and located in its use position with shingles 8 affixed thereto. It is appreciated, however, that the shingles do not cover air louvers or vent openings 10 and 12 of ridge vent 2. In the illustrated embodiment, leading edges 14 and 16 extend along both longitudinal sides of ridge vent 2 and are believed to promote enhanced ventilation by drawing air out of both sides of the vent. Leading edges 14 and 16 of the sides form a delta wing-shape design having a compound curve cross-section 15 and 17, respectively. For purposes of this disclosure, a compound curve is a curve made up of at least two arcs of distinct radii and having a common target at their point of juncture. This design is believed not to cause a back draw of materials, such as rain or snow, into the ridge vent on the non-windward side of the same. This is believed a problem with traditionally baffled vents.

(31) Vent openings or louvers 10 and 12 are located on the top of ridge vent 2 between shingle area 18 and leading edges 14 and 16 respectively. Vent openings 10 and 12 help keep material from getting trapped in ridge vent 2. Illustratively, a plurality of weep holes 20 may be formed on lower or bottom edge 22 of the sides of ridge vent 2 to promote fast drainage of any water that gets into ridge vent 2.

(32) It is appreciated that ridge vent 2 is bendable to match the pitch of roof 4. A dual wall of alternating tabs 26 and 28 off end 30 of ridge vent 2 at its bend. It is further appreciated that ridge vent 2 may adjust, illustratively, between a 3/12 to a 16/12 pitch. It is also appreciated that vent 2 may be cut to any desired length. In an illustrative embodiment, ridge vent 2 may be made from a polypropylene, high density polypropylene or similar material suitable for a roof application.

(33) Top perspective, end, and end cut away views of ridge vent 2 are shown in FIGS. 2, 3, and 4. These views further illustrate the compound curve delta-wing-shape 15 and 17 on leading edge sides 14 and 16, respectively. It is believed the design creates an area of low pressure in front of ridge vent 2, as air passes over leading edges 14 and 16. Furthermore, this particular leading edge shape gives ridge vent 2 a unique appearance with a darker shadow line and lower profile making it less noticeable from the ground. The hook shape of the vent area is also believed to provide better protection from wind-driven rain and snow.

(34) Also shown in FIG. 2, are nail lines 32 and 34, and center alignment and slot guides 36 located on the top pane of vent 2. Louvers 10 and 12 located on top panel 13 keep material from getting trapped in the vent area. The end and cross-sectional views in FIGS. 3 and 4, demonstrate how end tabs 26 and 28 are in an overlapping-type arrangement to close off the end ridge vent 2 when it is folded over the roof peak.

(35) An end cross-section view of ridge vent 2 attached to a roof 4 is shown in FIG. 5. This view also shows illustrative air flow paths 38, 40, 42 both inside and outside of roof 4. Illustratively, air flow 38 from inside the roof exits the louvers 10 and 12 to the outside as shown, when the wind direction is illustratively traveling from left to right. The opposite takes place with the wind direction traveling from right to left. As shown in FIG. 5, a hook or wave-shape air flow 40 is formed that directs air flow over louvers 10 and 12 located on both sides of top panel 13 of ridge vent 2. It is believed that leading edges 14 and 16 with profiles 15 and 17 help pull air out of the attic as wind passes over the ridge vent. It is not believed that the leading edge creates draw from the non-windward side of ridge vent 2, as indicated by reference number 42. This is desirable so material from outside is not pulled into the attic through ridge vent 2. The compound curve or delta-wing profiles 15 and 17 may result in areas of low pressure forming in front of the sides of the ridge vent, as air passes over the leading edge.

(36) An underside view of ridge vent 2 is shown in FIG. 6 depicting further underside features of ridge vent 2. This illustrative embodiment shows rows of ribs 44, 46, 48, and 50 extending from underside 52 of top panel 13. These rows of ribs 44, 46, 48, and 50 illustratively extend parallel to louvers 10 and 12 and to longitudinal axis 54 along the longitudinal extent of ridge vent 2. Individual ribs, however extend transverse to longitudinal axis 54. Also, the rows of ribs 44, 46, 48, and 50 are illustratively offset from each other and positioned on the underside of top panel 13 between rows of louvers 10 and 12. Also extending from the underside surface 52 of top panel 13 are rows of inner wall tabs 56 and 58. Each row includes a tab located behind one of the plurality weep holes 20. In the illustrative embodiment, tab rows 56 and 58 extend essentially parallel to longitudinal axis 54 and each row 56 and 58 are located outside the rows of louvers 10 and 12. In other words, rows of louvers 10 and 12 are positioned between the rows of inner wall tab rows 56 and 58 as shown. It is further appreciated, that with respect to ridge vent 2's interior space, the net free area for any air flow pathway shown via the gross cross-sectional area is believed calculated by the gross cross-sectional area less the area of any physical obstructions at the smallest and most critical cross-sectional area of the airway. It is appreciated that exterior openings into the attic space should have openings that will prevent the entry of birds, squirrels, rodents, snakes, and other animals. The louver openings may should, therefore, be a minimum of -inch and not exceed -inch.

(37) The vent slot opening in the roof should be illustratively sized to provide the required air flow in addition to the protection. In an illustrative embodiment, the vent openings for this ridge vent are about 0.126 inches wide by about 1.25 inches long. In a typical 4 foot length, there may be illustratively about 464 louvers in rows 10 and 12 on the underside of top panel 13 of the vent. The total square inches of opening on the top surface of the vent is about 73.08 square inches. The area of opening for the vent is about 18.27 square inches per lineal foot. It is appreciated that such a balanced ventilation system may allow heat and moisture to escape from the attic. It also may help prevent ice from damaging and prematurely deteriorating shingles by keeping the added temperature closer to the outside temperature. Ridge vents and soffit vents may be sized to work with each other. This is why the net free ventilation area of the vent is useful information.

(38) A perspective underside detail view of a portion of ridge vent 2 is shown in FIG. 7. In the illustrative embodiment support rib rows 44, 46 (as well as rows 48 and 50) hold up top panel 13 of ridge vent 2 when installed on roof 4. They also provide strength and support to the nailing line 32 and assist keeping the vent from crushing during installation. At the same time, rib rows 44, 46, 48, and 50 are designed not to impede air flow. In the illustrated embodiment, the support ribs are formed with a rounded inject pins 60 on each side. In addition, each row of ribs 44 and 46, and 48 and 50 are positioned offset from each other in the illustrative manner shown in the drawings. The row of inner wall tabs 56 (like row 58), are positioned behind weep holes 20 to block entry into the vent area.

(39) Outside and inside perspective detailed views of the ends of ridge vent 2 are shown in FIGS. 8 and 9, respectively. It is appreciated, and as previously discussed, ridge vent 2 is bendable along its longitudinal axis 54 to match the pitch of roof 4. End 30 of ridge vent 2 will, therefore, close by virtue of alternating tabs 26 and 28 (see, also, FIG. 1). By bending ridge vent 2 along its longitudinal axis 54, alternating tabs 26 and 28 will close off or fill in space therebetween to form a wall. It is further appreciated that these vent sections may butt up against each other when installed. In an illustrative embodiment, injector pins 62 are offset on tabs 26 towards the interior of ridge vent 2 to make sure the end of the vent is able to be abutted against an adjacent ridge vent. The inner row of alternating tabs 28 also have injector pins 64, each located at about the center of each tab. End pins 66 are located at the periphery of the rows of alternating tabs 26 and 28 to further assist sealing off the end of ridge vent 2 when bent along longitudinal axis 54 over roof 4. The view in FIG. 9 further shows the rows of ribs 44, 46, 48, and 50. The row of louvers 12 are shown in position adjacent the row of ribs 50.

(40) A detail underside perspective view of a corner portion of ridge vent 2 is shown in FIG. 10. This view depicts rib rows 48 and 50 located adjacent louver row 12. An interior wall 70 that forms delta wing edge 17 is shown with supporting inner wall tab 58. Again, each tab is located behind a weep hole 20. It may be appreciated from this view how rib rows 48 and 50 (as well as 44 and 46) and the row inner wall tabs 58 (as well as the row of inner wall tabs 56) assist providing support to ridge vent 2.

(41) An underside view of another illustrative embodiment of ridge vent 2 is shown in FIG. 11 where rows of ribs 72 and 74 may be located adjacent row of louvers 10. Rows 72 and 74, however, do not include injection pins like the prior embodiment. This is the same with the alternative embodiment of inner wall tabs 78 in contrast to injector pins on tabs 58 with injector pins formed thereon.

(42) It is appreciated that the vent as designed may adjust from a 3/12 to about a 16/12 pitch. It is further appreciated that ridge vent 2 may have different widths. For example an illustrative 11-inch wide ridge vent version may accommodate standard cap shingles; a 9-inch wide ridge vent may be used with dimensional cap shingles; and an illustrative 13-inch wide ridge vent may accommodate metric cap shingles. It is appreciated that the shingles do not cover the vent openings. Again, the louvers are located on top panel 13 and the shingles do not cover them when installed. It is further appreciated that these ridge vents have a particular leading edge design that promotes better ventilation by drawing air out of both sides of the vent for all three sizes shown.

(43) Top perspective detail and cross-sectional detail views of portions of ridge vent 2 are shown in FIGS. 12 and 13. Weep holes 20, located on bottom edge 22 at the sides of ridge vent 2 assist draining any fluid that enters the ridge vent. Also shown are inner wall 70, and the row inner wall tabs 58, each of which is located behind one weep hole 20 as previously identified. Again, inner wall tabs 56 and 58 assist in stopping wind-driven rain from entering further into ridge vent 2. As shown in these drawings, the plurality of weep holes 20 are positioned at regular intervals along bottom edge 22 of the sides of ridge vent 2.

(44) The cross-sectional view of leading edge 14 shown in FIG. 13 also depicts delta wing or compound curve profile 17 (the same will be the case for compound curve 15 as well). For both delta wing profiles 15 and 17, there is a curved edge 80 that extends slightly downwardly over channel 82 located between curved edge 80 and opposed sloped edge 84. With regard to sloped edge 84, it illustratively includes weep holes 20 and terminates at bottom edge 22. It is respectfully believed that this design assists preventing air that blows across ridge vent 2 from entering louvers 10 and 12 (see, also, FIG. 5).

(45) It is still further appreciated that ridge vent 2, may include either a higher or lower profile embodiments. For example, ridge vent 2 may have about a 0.92-inch height or about a 0.69-inch height. Both heights provide similar leading edge configurations as previously discussed. A lower profile shown provides a unique appearance with an even darker shadow line and lower appearance perceived profile, making it less noticeable from the ground. It is appreciated that in the illustrative embodiment shown, the lower profile vent may have a decreased vent opening, totaling about 12.7 square inches per lineal foot. The lower profile may also be installed with a coil nail gun for faster installation.

(46) Perspective partial cutaway and detailed sectional views of ridge vent 2 are shown in FIGS. 14 and 15. These views demonstrate nail locator 86 that may be formed on top panel 13 of ridge vent 2 along nail line 34 (as well as nail line 32). As shown, nail locators 86 are not holes, so when a nail is installed through the plastic material, it too seals around the nail. It is appreciated that indent portion 88 of nail locator 86 assists in the initial alignment for nailing into roof 4. Indent portion 88 has an angled base that may help hold the nail tip as it is driven through ridge vent 2. In an illustrative embodiment, there may be six nail locators 86 used on a 4 foot section of ridge vent 2. It is further appreciated that ridge vent 2 is configured so that additional nails will go through the nailing area when the cap shingles are installed over the center of the vent. It is also appreciated that nail lines 32 and 34 run down rows of ridge vent 2 as shown here and in FIG. 1. It is further appreciated that ridge vent 2 may be installed in full sections or may be cut into desired lengths. It is appreciated from this view, particularly FIG. 10 in contrast to FIG. 8, that the nailing area may run between rows of support ribs.

(47) Perspective and side views of a rollable version 90 of ridge vent 2 are shown in FIGS. 16 and 17. Rollable ridge vent 90 allows flexibility in both manufacturing variable lengths and installing a longer section of ridge vent. As shown in FIG. 16, ridge vent 90 is simply unrolled and then cut as needed. Cut line guides 92 may be located about every foot as a measuring and cutting guide. Illustratively, ridge vent 90, such as that shown, may be rolled in 10, 20, 30, and 50 foot lengths.

(48) Underside perspective and underside views of ridge vent 96 having a filter material 98 applied thereon are shown in FIGS. 18 and 19. A perspective view of a rollable ridge vent 100 with a filter material also applied thereon is shown in FIG. 20. Filter materials 98 and 102, such as that shown in these figures, may be added as a layer of protection to stop snow and/or dust from entering the attic cavity. It is appreciated that such a filter should not affect the air flow and the net free ventilation area of the ridge vent. In an illustrated embodiment, the filter material may be a loose, interlocking material that has low material density to serve as a barrier, but does not substantially affect air flow. The filter may be located in the underside center of the vent and cover the slot that is cut in the peak of the roof. In an illustrative embodiment, the filter may avoid the nail supports. It is appreciated that the filter may be attached to the ridge vent by various means, including gluing, hot staking, or mechanically attaching it with fasteners such as rivets, staples, or screws. Another mechanism for attaching the filter is to have pins with points on the underside of the vent. The filter may then be pressed onto the pins and using a heat probe to secure the filter in place. The view shown in FIG. 20 includes filter material 102 in the rolled ridge vent 100 embodiment. It is appreciated that filter material 102 may act and be attached, just as that previously described, but here may be installed in a rolled ridge vent.

(49) Perspective detail, bottom detail, and cutaway views of another illustrative embodiment of a ridge vent 110 are shown in FIGS. 21, 22, and 23. This alternative wave edge design includes a repeating wave edge 112 extending along the edge profile of the sides of ridge vent 110. This wave design creates a sharp lip 114 with recessed areas designed to create pockets of low pressure in front of the vent to promote air flow out of same, while protecting it from wind-driven rain and snow. Weep holes 116 are located at or adjacent the furthest extending point on the waves to protect and better provide drainage. The side of the vent is capped with this repeated structure along the sides of the ridge vent to create greater surface areas to the outer profile of the vent.

(50) Perspective detail and cross-sectional views of another illustrative embodiment of a ridge vent 120 are shown in FIGS. 24 and 25. These views show an alternate outer edge profile design having dual walls 122 and 124. In this illustrative embodiment, louvers 126 are seated lower than the outside leading edge. Shingles are still installed along the center of the vent, however. Illustratively, louvers 126 may be thicker in depth for greater support. Additionally louver 125 may be located in recessed channels 127. A taper 129 may be formed at louvers 126 to give improved protection to the interior of the vent.

(51) A plurality of illustrative edge profile designs for use as part of ridge vents 130 through 146 are shown in FIG. 26A through 16H. These illustrative, leading edge designs may be used to affect the air flow and weather protection for the ridge vent.

(52) Another illustrative embodiment of the present disclosure provides a ridge vent 162 that includes additional support ribs periodically located along longitudal extent of the ridge vent 162. As shown in the underside view of ridge vent 162 of FIG. 27, much of it is structurally similar, if not the same as, that shown in the previous embodiments, including the louvers 10 and 12, leading edges 14 and 16 with the delta wing-8 cross sections 15 and 17 respectively, and rib rows 44, 46, 48, and 50. Ridge vent 162 differs, however, in that it includes plurality of support ribs 164 and 166 periodically spaced in row form as shown in FIG. 27. It is appreciated that these rib supports 164 and 166 extend from a rib to a tab (such as tabs 168 and 170, respectively). It is appreciated that plurality of tabs 168 and 170 are similar to the tabs 56 and 58 previously discussed with respect to ridge vent 2.

(53) The detail underside perspective view of ridge vent 162 further depicts ridge vents 164 tied into tabs 168 as illustratively shown in FIG. 28. It is appreciated that rib supports 166 tie into corresponding ribs 170 in the same manner. It is appreciated that support ribs 164 and 166 may be periodically placed along the longitudal extent of ridge vent 162 to provide additional structural support of same. Another illustrative embodiment, rib supports 164 and 166 may be placed in the vicinity of nail locaters such as nail locaters 86 from ridge vent 2. This configuration allows further structural support of the ridge vent during installation when nails are being inserted through the nail locaters.

(54) Although the present disclosure has been described with reference to particular means, materials, and embodiments, from the foregoing description, one skilled in the art can easily ascertain the essential characteristics of the disclosure, and various changes and modifications may be made to adapt the various uses and characteristics without departing from the spirit and scope of the disclosure.
