Abstract

A ventilating system for a roof (40) made of a multi-plied weatherproof material (200). The weatherproof material includes a planar ply (204) and a second ply (208) joined such that a multiplicity of air passages (144) is defined thereby. The air passages extend generally transversely to longitudinal axes of the embodiments. Each embodiment can be transported and stored in a spiral conformation. The spiral conformation is achieved by rolling the embodiment in a direction generally parallel to the longitudinal axis. A series of embodiments include a top panel and one or more lateral vents, rolled such that the one or more lateral vents are radially exposed. When shipped and stored in a spiral conformation, the embodiment with radially exposed lateral vents is more quickly and easily installed on a roof. Another embodiment, also conformable to a spiral for shipping and storing, is advantageously used to enhance ventilation by ventilating the eave.

Description

VENTILATION DEVICES FOR CEILINGS THAT CAN BE ROLLED AND METHODS FOR USING THEMSELVES CROSS REFERENCES TO RELATED REQUESTS The subject matter of this application relates to the subject matter of US Application No. 09 / 002,538, filed on January 2, 1998, which is incorporated herein by reference and to the priority claimed. under 35 USC §119 (e) ..

FIELD OF THE INVENTION The present invention relates to ceiling ventilation devices, and particularly the present invention relates to ceiling ventilation devices made of corrugated materials that can be shaped into a spiral for shipment and storage.

BACKGROUND OF THE INVENTION Insufficient ventilation in the ceiling could result in a prolonged interaction between humid air at rest and a colder surface. The condensation of moisture on the coldest surface occurs when these conditions occur. Condensed moisture often damages and stains ceilings. In more severe cases, structural members such as joists and tacks are wetted continuously and become unsafe. Buildings with not sufficiently ventilated roofs also tend to be hotter in the summer months due to the presence of air heated by the sun that is trapped. These constructions are more expensive to maintain at adequate temperatures than if the ceilings of the same had sufficient ventilation. When there is sufficient ventilation, the air is kept moving as it circulates from outside the roof to the attic, coming out through the vents often placed near the trestle. This ventilation is necessary to prevent the accumulation of hot air or condensed moisture. Several products have been developed to provide forms of ventilation. These products provide either separate ventilation structures or are in themselves construction materials with ventilation properties. A particular type of design requires that an opening or slot be made in the roof or near the roof ridge. A vented coating is placed over the opening and fastened to the ceiling along each side of its ridge. Ventilation is channeled through air passages within the vented sheath extending down the ridge towards the eaves. U.S. Patent No. 4,803,813 to Fiterman and U.S. Patent Nos. 5, 094,041 and 5,331, 783 to Kasner et al. , describe various methods for notching, bending and tracing pieces of corrugated plastic sheet material to form folding roof vents, as well as methods for the installation and use of these vents. These folding ceiling fans were commonly manufactured and sold with an approximate length of 1.21 meters. A double-length hinged roof vent, described in US Patent No. 5,304,095 to Morris, improved the delivery and installation of such roof vents. Other types of roof covering products such as flat roof tiles, tarred paper and some ceiling ventilation products made of wool fiber or other materials are rolled out. The distribution in rolled form allows that a greater quantity of these products as far as length is sent and installed. Furthermore, the installation of these rolled products eliminates or reduces some potentially undesirable characteristics such as frequent openings and joints. U.S. Patent No. 5,651,734 discloses a ceiling fan with a multi-layer hinged cover. The fan is made of double-sided corrugated plastic sheet material and includes two opposed vents. After its manufacture, the plastic sheet material is wound into a spiral, being held in the spiral by means of bands for its delivery. Upon arrival at the installation site, the roll is transported to the roof, unrolled and the panels with incisions are folded consecutively to form the opposite ventilation parts. Then, the finished fan is fastened to the ceiling. Heretofore, those skilled in the art have been forced to choose between the advantages of corrugated plastic ceiling fans with multiple layers that can not be rolled up and rolled ceiling products that can not provide the advantages of a corrugated plastic product. multiple layers. Furthermore, the above choice often requires additional steps to be carried during installation and to convert a rolled and incised piece of double-sided corrugated plastic sheet material into a multi-layer assembled ceiling fan. Those skilled in the art will appreciate other improved features in roof vents made of corrugated materials. These products offer economic and efficient features such as shipping, handling and more efficient storage. These products also offer improved features that reduce the time and effort required for their installation.

BRIEF DESCRIPTION OF THE INVENTION A roof ventilation device is provided that includes a primary vent. The primary vent includes a primary panel made of a waterproof material. The waterproof material includes primary and secondary laminae bonded to allow a large number of primary air passages to be thus delimited. The waterproof material could include a flat sheet and a rolled sheet. An alternate waterproof material includes two planar sheets and a rolled sheet. Each planar sheet is attached to the rolled sheet so that a large number of air passages are defined according to the above. Another alternate water proof material includes two planar sheets joined by a plurality or large number of cross walls so that a large number of air passages are defined according to the foregoing. The internal and external openings are defined in the waterproof material at least in a portion of the primary air passages. The air passages extend generally transverse to a longitudinal axis of the ventilation device. The first vent can be formed in a spiral by winding in a direction generally parallel to the longitudinal axis. Also, a fan is provided in which a plurality of the primary panels is present and where the primary panels can be fastened together in a general underlying relationship. Likewise, a vent is provided that can be placed in a place on the roof in which there is a change in the inclination of the same. The vent includes a top panel made of any of the waterproof materials. The air passages defined by the waterproof materials in the top panel are generally parallel to the air passages of the primary panel. The fan can also be formed in a spiral. When in a spiral or roll form, a portion of the vent could be radially external to a clamped portion of the top panel.

Likewise, a ventilation device is provided which additionally includes a secondary vent manufactured from any of the waterproof materials described above. The second vent includes a large number of secondary air passages defined by the waterproof material. The secondary air passages extend generally parallel to the primary air passages. A top panel of the second vent is attached to the top panel in a general underlying relationship. An angular support is also provided which is placed in the lower part of the upper panels of the vents described herein. Additionally, the angle bracket is placed on a portion of the roof underlying the top panel. The angular support prevents the entry of rainfall when it is in place. Also, an air diverter including primary and secondary planar portions is provided. The first planar portion is placed below a panel of the vents described herein. When placed in this way, the air diverter deflects the air flow and thus inhibits the entry of precipitation into the air passages close to the secondary planar portion of the air diverter. Also, an articulated vent is provided to be placed on the roof. The articulated vent includes a top panel and ventilation means. The upper panel defines a longitudinal axis, primary and secondary ends, primary and secondary lateral ends as well as an internal and external surface. The ventilation means are subject to a corresponding portion of an inner surface of the upper panel. The means of ventilation include a large number of air passages. The ventilation means define an internal opening and an external opening for at least a portion of the air passages. The articulated vent is assembled to form a primary coiled form for shipping and a secondary coiled form for placement or installation on a roof. In the first rolled form, the ventilation means show a greater radial distance protruding from the center of the hinged articulated vent to any upper panel subject to the corresponding ventilation means. Also, a method for manufacturing a device for venting a roof is provided. The method includes the steps of providing any of the aforementioned waterproof materials that define a large number of air passages; defining a primary panel in the waterproof material so that the air passages extend generally transverse to a longitudinal axis of the first panel; defining the outer openings in at least a portion of the large number of primary air passages; and confirming the primary panel in a spiral by winding the primary panel in a direction generally parallel to the longitudinal axis of the primary panel. Likewise, another method is provided for manufacturing a device for ventilating a roof. The method includes the steps of providing any of the above-described waterproof materials that define a large number of air passages; defining the primary and secondary panels in the waterproof material so that the air passages in the primary and secondary panels generally extend transverse to a longitudinal axis of the primary panel; placing the primary and secondary panels in a general underlying relationship; and forming the primary and secondary panels in a spiral by winding the primary and secondary panels in a direction generally parallel to the longitudinal axis of the primary panel. The method could include forming the primary and secondary panels so that the primary panel forms a primary radial distance from the center of the spiral, the secondary panel will be at a radial distance from the center of the spiral, and the primary radial distance will be less than secondary radial distance. Also, a method is provided for installing a ventilation device in a roof with a slot defined by a coating layer. The method includes the steps of providing a ventilation assembly, the ventilation assembly will include a primary panel made of any of the waterproof materials described herein, the waterproof materials will generally extend transverse to an axis longitudinal of the primary panel, the ventilation assembly will be formed into a spiral by winding the primary panel in a direction generally parallel to the longitudinal axis of the first panel; when unrolling the ventilation assembly; and when placing or holding the ventilation assembly unrolled to the ceiling. The method for installing a ventilation device could also include a ventilation assembly with primary and secondary panels, the secondary panel near the primary panel in a general underlying relationship, the primary and secondary panels formed in a spiral in which the secondary panel is exposed radially in the spiral and additionally includes the step of placing the secondary vent next to the slot. The method for installing a ventilation device could also include a vent with a primary, secondary and tertiary panel, the secondary panel opposite the tertiary panel, secondary and tertiary panels close to the primary panel in a general underlying relationship, the primary, secondary panels and tertiary formed in a spiral, the secondary and tertiary panels being radially exposed in the spiral. A method is also provided for installing a ventilation device in a roof eaves. The method includes the steps of providing the ventilation device, the ventilation device will be manufactured from any of the waterproof materials described herein and with a large number of air passages that extend generally transverse to an axis longitudinally of the ventilation device, the ventilation device should be able to conform to a spiral by winding the ventilation device in a direction generally parallel to the longitudinal axis; and when placing the ventilation device near the eaves. Another method or process is provided to form a roof vent. The vent is formed from a waterproof material with a grooved layer placed between the generally planar primary and secondary layers so that a large number of generally parallel air passages are formed. The process includes the steps of providing a sheet of waterproof material; forming a pair of primary side slots, a longitudinal axis of the sheet generally positioned between the primary side slots, each primary side slot extending through the secondary planar layer and at least partially through the ribbed layer, thereby defining a panel upper and side panels arranged laterally; folding each side panel into an underlying relationship to the top panel through automatic or manual folding means; holding each side panel to the top panel by automated or manual fastening means, thereby forming a vent; and forming the vent in a spiral configuration by winding the vent along the longitudinal axis.

DETAILED DESCRIPTION OF THE DRAWINGS This is a continuation-in-part of U.S. Application No. 08 / 828,257, filed March 26, 1997. U.S. Application No. 08 / 828,257 is in turn a continuation in part of the Patent. No. 5,651,734. Roof vents are described in U.S. Patent Nos. 4,803,813; 5,094,041; 5,304,095; and 5,331,783. A wind deflector and an angular support are respectively described in US Requests Nos. 08 / 127,005 and 08 / 126,307, both filed on September 24, 1993. All US patents and applications listed above are assigned to the present assignee and they are incorporated herein by reference into this specification as having been enumerated in their entirety herein, including but not limited to their descriptions. In Fig. 1, an upper fragmented cross section of the roof 40 is illustrated. An exemplary roof fan 44 is being installed on the roof 40. The roof 40, in this example, is a reinforced roof. However, those skilled in the art will appreciate that other forms of roof could receive ventilation when installing the present invention. The exemplary roof 40 includes the upper cords 48 and the liner or cover 56. The ridge or apex 60 of the roof 40 is formed by opposing it closely to the upper cords 48, which are joined at the ridge 60. The upper cords 48 will be alfardas attached to the trestle table 52 (Figure 22) at the ridge 60 if the roof 40 is a roof of rafters. The liner or cover 56 often consists of counterplated sheets or planks (not shown) that overlap and are attached to the upper cords 48. The cutting pieces 68 are present in the cover 56. A cutting part 68 is arranged on each side of the ridge 60, starting at a distance from the sprocket wall 71 of the roof 40 in this example. The overlay 56 is a layer of felt paper 72. The outer roof 76, like the flat asphalt shingles, is overlapped with the felt paper 72. The ridge 60 extends generally along the longitudinal axis 78 thereof. Ridge vent 44, as shown in Figure 1, extends generally along the longitudinal axis (or longitudinal center line) 92. The primary 96 and secondary 100 ends, as well as the primary side edge 104 and the side edge secondary 108 are present in the vent of the ridge 44. The vent 44 generally includes the top panel 110. One or more side vents 112 could also be present. In this embodiment, the upper panel 110 defines the upper sur 116, the lower sur 120, the primary end 124, the secondary end 128, the primary side edge 132, and the secondary side edge 136. On the lower sur 120, the route 140 is provided optionally. The route 140 extends together with the longitudinal axis 92 in this mode. However, other orientations could be presented for route 149. A large number of air passages 110 is present within upper panel 144. Air passages 144 generally extend from route 140 to each lateral edge 132, 135 in upper panel 110. Air passages 144 extend generally transverse (eg, perpendicularly) to longitudinal axis 92.

Each air passage 144 terminates in an internal opening 148 and in an external opening 152. The internal openings 148 are defined by route 140. The external openings 152 are defined by each of the lateral axes 132, 136. The air passages 144 they are described more fully below. Each exemplary vent 1 12 includes at least one of the ventilation panels 160-162. In Figures 1, 2, 5, 12, 21 each side vent 1 12 includes three or more ventilation panels 160-162., any number of ventilation panels could form a lateral vent 12 and be within the spirit and scope of this invention. Generally, the side vents 12 include the primary end 164, the secondary end 168, the inner edge 172, and the outer edge 176. Corresponding in a dimensional manner to the side vents 1 12 in this embodiment, each ventilation panel 160-162 it includes a primary end 180, a secondary end 184, an inner edge 188, and an outer edge 192. Also, a plurality of air passages 144 are present in each ventilation panel 160-162, which therefore are also found present within each side vent 1 12. The air passages 144 are defined in the same manner as described above in relation to the top panel 1 10. In this embodiment, the outer edges 192 of the ventilation panels 160-162 can generally aligned together with the primary and secondary side ends 132, 136 of the top panel 1 10. Thus, an opening 196 exposes the bottom surface 120 of the panel upper 110 and the internal ends 172 of the side vents 112. The primary and secondary ends 180, 184 of the ventilation panels 160-162 of the side vents 112 could coincide with the primary and secondary ends 124, 128 of the upper panel 110 The exemplary top panel 110 and ventilation panels 160-162 can be made of a three-sheet water-proof material 200. As shown in Figure 11, the material 200 generally includes the primary planar sheet 204, secondary planar sheet 208, and the rolled (or fluted) sheet 212. The sheets 204, 208, 212 are joined together so that the air passages 144 can be defined therebetween. A three-sheet waterproof alternate material 216 is illustrated in FIG. 9. The waterproof material 216 includes the primary planar sheet 220, the secondary planar sheet 224, and a series or large number of cross-walls 228. Cross walls 228 generally extend transversely (eg, perpendicularly) between planar sheets 220, 224. Planar sheets 220, 224 and cross walls are joined together so that a large number of air passages 232 are defined therebetween. . Figure 10 illustrates a double sheet material 236 as another alternative embodiment of the waterproof material. The double sheet material 236 includes a planar sheet 240 and a rolled sheet 244. The planar sheet 240 and the rolled sheet 244 are joined together so that a large number of air passages 144 are defined therebetween. Still further, when two or more layers of double sheet material 236 are folded so that the rolled sheets 244 are confronted and generally contact each other, a large number of air passages 248 are formed therebetween. The waterproof materials 200, 216, and 236 could be formed from high density polyethylene or other synthetic resin. However, the waterproof materials 200, 216 could also be formed from corrugated cardboard coated with a sealer such as epoxy to protect the cardboard from deterioration due to moisture and similar elements. In addition to being impervious to moisture, suitable materials should also resist weathering from exposure to solar radiation and heat. Corrugated polyethylenes could be obtained from U.S. Corrulite, Inc., South Bay, Florida (or Winona, Mississippi) and Fremont Direct Products, Inc., Fremont, Ohio. Figure 4 shows the vent 44 that will be formed from a unitary sheet 260. The sheet 260 is formed from the aforementioned materials. A series of cutting incision lines 264, 266 define the upper panel 110 and the ventilation panels 160-162. The incision lines 264, 266 extend generally parallel to the longitudinal axis 92. Figure 12 illustrates the upper panel 110 and the primary ventilation panels 160 as formed by an opening extending in the primary planar sheet 204, and the opening that is extends 254 at least partially through the rolled sheet 212. The intermediate ventilation panel 161 is laterally adjacent to the first formed ventilation panel 160. The intermediate ventilation panel 161 is partially defined along the line of ventilation. incision 266. Incision line 266 is formed by extending an opening through a secondary planar sheet 208 and at least partially through a rolled sheet 212. Finally, the intermediate ventilation panel 161 and the ventilation panel on the side of the 162 are fully defined by extending the score line 264 as described above. Therefore, having been defined by the incision lines 264, 266, the panels 160-162 are folded below the upper panel 110 in accordance with a Z-shaped folding technique. The closing methods or closing devices 268, such as staples, are placed through the upper panel 110 and in each of the ventilation panels 160-162 as shown in figures 28,29. Figure 1 illustrates the route 140 as it extends jointly with the longitudinal axis 92 in this embodiment. Route 140 is defined on lower surface 120 by removing a generally linear portion of planar sheet 208 and an underlying portion of rolled sheet 212. As can be seen in Figure 7, route 140 is generally arched in cross section . However, other cross-sectional conformations are possible, which have certain advantages that are described herein. An alternate cross-sectional geometry is illustrated in FIG. 8 as the route 280. Route 280 is formed by removing the planar sheet 208 and the underlying portions of the rolled sheet 212, leaving the planar sheet 204 intact. Instead of an arched cross section as in route 140, route 280 is generally square or rectangular in cross sections. As in the passage of the route 140, where the route 280 is being defined, the internal openings 148 for the air passages 144 are also defined. Other alternate cross-sectional geometries for the route defined within the upper panel 110 include a notch in V-shape (which is not displayed). A less suitable definition could be a fold (which is not displayed). If there is only one fold, the internal openings 148 could not be defined. Therefore, the air passages 144 would not be present within the upper panel 110 in such a manner as to allow ventilation. Therefore, the routes 140, 280 serve to define the external openings 148 of the air passages 144. The routes 140, 280 also allow the vents 44 to be folded easily and accurately generally along the longitudinal axis 92. during installation to conform to the contours of the roof 40. Accordingly, the vent 44 could include a top panel 110 and opposed side vents 112. As shown in Figure 1, each side vent 112 includes at least one vent panel 160. Having formed from a unitary sheet 250 of waterproof material in the manner described above, a large number of air passages 144 are present in the upper panel 10 and each ventilation panel 150-152. air passages 144 in the upper panel 1 10 and each ventilation panel 160-162 are generally parallel to each other and are generally transverse to the longitudinal 92. Even more, when properly oriented, the air passages 144 define a grain G. Therefore, Grain G indicates that air passages 144 generally extend transversely (e.g., perpendicularly) to the longitudinal axis 92. As shown in Figure 22, the upper panel 10 could only be used as a vent to allow air exchange in some ceiling designs. Therefore, the air passages 144 extend generally transverse to the longitudinal axis 92. The route 140 or other embodiment thereof is also defined as a longitudinal axis 92 proximate or jointly extensive as defined above. The upper panel 10 when used alone, could be formed from a unitary sheet of waterproof material so that one or more routes 140 define internal openings 148 of air passages 144. Route 140 also allows the upper panel 1 10 is conveniently folded along the longitudinal axis 92 and therefore better conforms to the opposite contours of the roof 40.

Figure 21 illustrates an alternate method for forming an upper panel 10 and vent panels 160-162 from the sheet 260. As in the case of the score lines 264, 266, the perforated lines 284 generally extend from shape parallel to the longitudinal axis 92. However, in contrast to the score lines 264, 266, the perforated lines 284 are formed from a series of perforations 288 that extend through the sheets 204, 208, 212. Intact areas 290 they are sandwiched between the perforations 288. The perforated lines 284, therefore the perforations 288 therefore define the upper panel 1 10 and the ventilation panels 160-162. The perforations 288 further define the external openings 152 for the air passages. 144. Once formed, the ventilation panels 160-162 could be folded in a Z-shape under the top panel 1 10 as described above and secured to each other by means of of a closure 268 as described above. As shown in Figure 3, a series of elongated slots 294 could be present in the ventilation panels 160-162. The slots 294 could be present in two unleveled rows, each uneven row being generally parallel to the longitudinal axis 92. The slots 294 interrupt the air passage 144 and thus inhibit the ingress of moisture into the opening 196. On the other hand, the upper panel 1 10 and ventilation panels 160-162 could be defined by completely separating the ventilation panels 160-162 from the unitary sheet 260. Once separated, the ventilation panels 160-162 could be stacked below the upper panel 110 and fastened thereto by means of closures 268 such as staples or equivalent closing means, as shown in Figure 5. With reference to Figure 23, the roll 300 is formed by winding assembled vents 44 in a direction generally parallel to the longitudinal axis 92 so that the side vents 112 are exposed in an outer portion of the roll, in addition to said portions being exposed in the the ends of each roll. Once they are in the desired spiral shape, the roll 300 is held by a band 302, or by similar latching means. On the other hand, a roll 304, as illustrated in FIG. 24, could be formed by a rolling vent 44 in a direction generally parallel to the longitudinal axis 92, so that the upper panel 110 is exposed to the outside thereof. As shown in Figures 26-27 the roll 308 could be formed by the roller vent 44, which has been formed by separating all or a portion of the panels 160-162 in the manner described above. The roll 308 is formed by winding the resulting vent 44 in a direction generally parallel to the longitudinal axis 92. The roll 308 generally includes rolls in which any of the side vents 112 or the top panel 110 are exposed radially. However, the roll 308 provides a less satisfactory appearance and utility to other embodiments described herein. By not being joined by joints, the ventilation panels 160-162 tend to buckle and curl as the roll 308 is formed. Therefore, when a vent 44 that is wound on the roll 308 is unwound on the roof 40 , it must be smoothed before its installation. The necessary smoothing activities will require additional time and effort during the installation process. In contrast, Figures 23-25 illustrate that rolls 300, 304 minimize or eliminate twisting or kinking that is present in roll 308. However, when unrolled prior to installation, top panel 110 of roll 304 it tends to arch upwards between the closure devices 268, as defined in Figure 29. Therefore, the roll 304, while being more satisfactory than the roll 308, still requires time to be smoothed and adapted to the shape of the ceiling 40. In contrast, roll 300 unwinds gently and therefore does not require additional time for installation, as shown in Figure 28 and as mentioned below. During its shipment, the panels on the outside of rolls 300, 304 and 308 could be subject to scrapes, lacerations or punctures. In the roll 304, the top panel is placed on the outer circumference of the roll and is subject to damage. Clearly, when the roll 304 is installed on a roof, a damaged upper panel 110 will not be able to protect the roof from infiltration by precipitation. However, in the roll 300 the upper panel 110 is positioned radially inwardly of the ventilation panels 160-162. This has many beneficial effects. One such effect is that panel 110 is more protected from damage during shipment. Other benefits are discussed below. It is believed that rolls 300 and 304 minimize kinking, in part due to the use of the Z-shaped folding technique described herein. The rolls 300, 304, 308 are formed by a rolling vent 44 in a spiral. Once in spiral form, adjacent panels in the form of layers 110, 160-162 will be subject to different stresses. Those panels located more radially outward will be more subject to different stresses than adjacent panels placed more radially inward. This difference in tension established in the adjacent panels could produce undesirable results. In the roll 308, the upper panel 110 and the ventilation panels 160-162 are not joined by means of joints but only with similar staples or closing devices. Because only the staples or other closing devices are present, the panels are free to wind up or to return to their position between these closing devices along a longitudinal axis. This problem becomes more serious as more panels are used in a way that allows self-positioning of the panels when they are subject to rolling stresses. However, the ventilation panels 110, 160-162 in the rolls 300 and 304 are folded into a Z-shape (or joined by means of joints). Therefore, in the rolls 300, 304 the panels 110, 160-162 will not be able to slip, roll or return to their position as easily as in the roll 308. This facilitates a more efficient and uniform spiral roll. Also, the radially outer panels in these rolls will tend to elongate more than the adjacent radially internal panels. Accordingly, when the panel 110 is positioned radially inward relative to the panels 160-162, the outer panels 162-160 will tend to elongate relative to its distance from the adjacent panel 110 and the panel 110 will not bow or twist when the panel 110 is closed. Roll 300 unwinds. Therefore, panel 110 will offer an additional advantage due to its smoothness, efficiency and ease of installation. Figure 1 shows the roll 300 being installed on the roof 40 when unrolling in a generally parallel to the stand 60. It can be unwound either the entire length of the roll 300 or the desired amount thereof. After having been unrolled from the roll 300, the vent 44 will conform to the roof 40 by bending longitudinally along the route 149. The side vents 112 are located towards the outside (or outside) of each cutting piece 68. Finally, the angular support 312 may be placed between the upper panel 110 and an underlying portion of the roof at the ends 96, 100. The angular supports 312 may also be placed at intermediate distances below the upper panel as the vent 44 is installed. Figure 2 shows closure devices 314 such as nails extending through upper panel 110 and angular support 312. Other suitable closure devices could be the staples and adhesives known in the art. The angle bracket 312 could also be coated with a caulking material before being installed to form a seal and to function as a lock. Roofing materials 76, such as flat asphalt shingles, could be installed over the vent 44. Finally, the closing devices 314 such as nails extend through the roofing materials 76, the upper panel 110, and the side vents 112 to the facing 56 A desirable feature of any of the vents of the present invention is that they can be installed with a nail gun without collapsing. Therefore, its ventilation capacity does not decrease when a nail gun is used for installation, due to the elasticity of the same. On the other hand, as shown in Figure 15, the hinged or vent covers 315 could be placed over the already installed articulated vent 44. A number of colors may be used to code various dimensions and modes of the vent 44. For example, the black could indicate a roll 44 with a width of twenty-three cm., a length of six meters and with three panels 160-162, while green could indicate the same panel design, but with a width of 29 cm. Once installed, the ridge vent 44 allows an advantageous exchange of air between an interior portion of the roof 40 and the exterior environment thereof. Therefore, each air passage 144, defined within the vent 44, allows air to flow generally from the interior to the exterior of the roof 40. Furthermore, virtually every element (upper panel 1 10, ventilation panels 160 -162) define a large number of air passages 144, and each air passage 144 is a conduit for air exchange. The angled supports 312 could be formed separately for installation as described herein. Figure 17 describes a continuous and generally rectangular or parallelepiped foam block 322. Angular supports 312 could be formed by defining the notches 324 within them. The angled supports 312 could be prepared for use in the installation by separating from the block 322 along the notches 324. However, the previously cut angular supports 312 could be formed directly, eliminating the need to cut individual angled supports 312 to shape the block 322. Corner blocks 312 and block 322 could be manufactured from a closed-molecule foam such as that sold by Dow called Ethyfoam MR, polyethylene or from a polyurethane foam. The angular support 312 has a length equal to or a little greater than the opening 196. The angular support 312 has a height and thickness generally equal to or slightly greater than the height of the side vents 1 12. Although the above is satisfactory for portions of ceiling with incision lines, another embodiment of the present invention could be used, as shown in figure 16, for other types of roof shaping. The vent 316 could be formed by longitudinally cutting a side vent 12 and an adjoining portion of the top panel 10 from the rest of the vent 44. The arched route 140 could be included within the top panel 318 of the vent 316. On the other hand. vent 316 could be prepared in a general manner as described above, excluding one of the side vents 1 12 and a corresponding portion of the top panel 1 10. Once formed, vent 316 could be used in portions of roofs including those that are describe below. Figure 16 shows a water deck roof or clew room type 340 including a series of rafters 344 attached to the side wall 348. Above the rafters 344 is the liner 56. The cut piece 68 has been cut from the liner 56 of the adjacent side wall. Also, the present and overlapped coating could be a layer of felt paper 72. The overlay felt paper is a roofing material 76 such as flat asphalt shingles. As it was installed on the deck to a water 340, the vent 316 includes a side vent 1 12 positioned to the outside of the cutting piece 68. The upper panel 318 expands toward the cutting piece 58, folds down, and is commonly secured to the side wall 348. On the other hand, a portion of the top panel 318 could be folded up and attached to the wall 348. Then, the side vent and the attached top panel are fixed to the liner 56 by means of closure devices such as nails or adhesives. Then, the cover 364 is installed on a portion of the top panel 318 and the adjacent side walls 348. The cover 364 is additionally attached to the side walls 348 above the vent 316. The outer skin 368 extends through a cover. upper portion of the cover 364. The roof 76, such as flat asphalt shingles, or other protective devices may be placed over the installed vent 316. As shown by arrows 372, the airflow increases from the interior to the exterior of the roof. the cover to a water 340 by means of the installed vent 316. As illustrated in Figures 13, 14 the vent 400 could be formed within the present invention. The vent 400 includes one or more ventilation panels 160-162. The ventilation panels 160-162 could be joined by any of the methods described above. The vent 400 could also be rolled as described above. The vent 400 could be formed from the remainder of the vent 44 when the vent 316 is formed therefrom. An advantageous use of the vent 400 is to allow air to enter a ceiling 402 near a protruding portion 404 thereof. As shown in Figure 13, the exemplary protruding portion 404 generally includes a lower portion of the sill 408, which extends outwardly and below the upper slab 410. At the outer end of the sill 408 is the spacer 412. The spacer 412 will have the size of the vent thickness 400. The band sheathing 416 is positioned toward the exterior of the spacer 412 and the vent 400. The sheath 56 is located on the upper part of the 408 sill. coating are the layers of felt paper 72 and roof 76, respectively. The soffit 420 extends between the vent 400 and the side wall 422. The soffit 420 is fixed to the nail strip 421, adjacent the side wall 422 and a lower part of the sill 408. The ceiling 424 extends inward from the upper plate 410. The insulation 428 is disposed above the ceiling 424. As shown in arrows 430, the air flow proceeds through the vent 400 and through the air passage 432 into the interior of the ceiling 402. Figure 14 shows an exemplary roof 440, which employs S-shaped roof tiles as roofing materials. At the roof 440, the opposing struts 444 are joined at an apex together with the ridge board 448 to form the ridge 450. The siding 56 and a felt paper layer 72 are positioned above the 444 slabs. same are the S-shaped shingles 452. The tile sill 454 is fastened above the S-shaped shingles and another table of the ridge 448 by means of a locking device 456. In this embodiment, the improved roof ventilation 440 is achieved by installing a vent 400 next to each of the sides projecting outward from the trestle board 448. The cover 364 is placed to the outside of each vent 440. The cover is attached to the roof 56. Finally , a layer of gypsum, cement or mortar 460 is applied on the cover 364. Therefore, the air passage 462 is formed as illustrated by the air flow arrows. Therefore, the air flow from the interior of the roof 440 proceeds through the air passageway 462, passes through the vent 400, below the tile lintel 454, and out between the openings between the S-shaped tiles 452. There are several desirable dimensions for the vents 44, 316 and for panel 1 18 when used as a vent. However, vent 44 has been shown to adequately fit roofs when used in widths of 20.06 cm and 28.57 cm (± 0.63 cm.), Although other sizes may also be appropriate. Side vents 1 12 could be used in widths of 5.08 and 7.62 cm. (± 063 cm.). The number of ventilation panels comprising the side panels 1 12 could be altered. Vents 1 12 with 3 and 5 ventilation panels have proven to be of satisfactory utility. The widths of the panel 10 should generally conform to those of the vents 44, 316. The dimensions of the vent 400 are expected to be 2.54, 5.08 or 7.62 cm (± 0.63 cm). As shown in Figures 18-20, the exemplary wind or air diverter 472 is optionally installed with the vents 44, 316. The air diverter 472 includes a planar base member 474 and a vertical member 476. The base member 474 defines the front edge 478, the trailing edge 480, and a pair of opposite end edges 482, 484. An opposite pair of notches 486, 487 are defined in the base member 474 near the junction of the trailing edge 480 at each edge end 482, 484. Rear edges 488, 489 are respectively present in notches 486, 487. Vertical member 476 ends up at edge 490. The vertical member defines a plurality of generally circular openings 492 close to front edge 478. The air diverter 472 could be manufactured from 26-gauge aluminum foil, die cut and folded up to achieve the above-described configuration. The vertical member 476 is attached to the base member 474 at an angle of approximately 75 ° relative to the plane of the base member 474. However, the vertical member 476 could be attached to the base member 474 at angles of between approximately 65 ° and 85 °. The edge 490 is attached to the base member 474 at an angle of between 120 ° and 140 ° for example at an angle of approximately 130 °. A circular aperture 492 could be defined at approximately 5.08 cm. Of each corresponding shaft 494, 496. The additional openings 492 could be spaced apart at approximate intervals of 10.16 cm. Each notch 486, 487 extends approximately to 5.08 cm. Of the corresponding end edges 482, 484. The length of the exemplary air diverter 472 is approximately 121.9 (± 2.54) cm. and its width is 6.667 (± 0.63) cm. The height of the air diverter 472, according to the measurement provided by the vertical member 476, is approximately 1.714 (+ 0.63) cm. The height of the edge 490 is approximately 0.63 (± 0.25) cm. Figures 19, 20 illustrate that the air diverter 472 can be placed at the same time as the installation of the vent 44, 316 is carried out. However, the air diverter 472 can also be placed to an already installed ceiling fan. During installation, base member 474 is inserted below a panel such as panel 162. However, base member 474 may also be inserted between two other ventilation panels. The insertion is carried out until the vertical member 476 is positioned at a specific distance from the outer edge of the vent part. The notches 486, 487 will serve as guides for positioning and aligning the air diverter 472 with the outer edges of the ventilation portions. Therefore, the base member 474 slides underneath the panel 162 until the edges 488, 489 align with the outer edge 192. When the air diverter 472 is in the proper position, the closing devices 314 such as nails , they extend through the overlying roof 76, the parts of the vent 1 12, and the base member 474 to the deck 56.

Figure 30 is a flow diagram illustrating an exemplary method for forming the vent 44. It is intended that the flow chart illustrated in Figure 30 and the following explanation be provided by way of illustration and not in a limitative manner, since variations to this sequence of the method are contemplated within the spirit and scope of this invention. In step 502 the waterproof material 200 is formed by a multiple extrusion process known in the art. The multiple extrusion process of step 502 forms a continuous sheet. The continuous sheet of waterproof material is separated to the desired widths in step 504, thus forming continuous sheets of corrugated plastic such as the plastic described in relation to sheet 260. The exemplary rolls could be of various widths, depending of the number of panels and the widths of the panels that make up the final vent. The grooves formed in step 504 preferably extend through layers 204, 208, 212 and are generally parallel to air passages 144. The continuous sheet could be wound on a mandrel in step 508, being cut when a length enough has been rolled in it. Then the roll can be stored according to step 510 until it is required for the rest of the process. The stored rolls are unwound in step 512. While unrolling in step 512, a route 140 could be formed in step 516. After being routed, the sheets 260 are cut in step 518. The cutting step 518 ensures that both lateral edges of the sheets 250 are generally parallel and that the upper panel 110 and the ventilation panels 160-162 have the desired dimensions. Step 518 allows upper panel 110 and ventilation panels 160-162 to be defined so that they generally extend jointly as described above. The incisions 264, 266 are formed within the cut sheets 260 in the passage 520, thus defining the upper panel 110 and the ventilation panels 160-162. The ventilation panels 160-162 are folded near the upper panel 110 in an underlying relationship in step 522. Step 522 could involve methods for automatically folding the ventilation panels 160-162 under the upper panel in a continuous process. However, manual folding of the ventilation panels 160-162 in an underlying relationship is also contemplated. Upper panel 110 and ventilation panels 160-162 are stapled together in step 524. Step 524 could include stapling by manual or automatic means at predetermined distances between each longitudinal end of the formed vent 44. Step 524 it could include the placement of staples by manual or automatic means at approximately 3.81 and 6.35 cm. each. Step 524 could include placing staples by manual or automatic means at approximately 5.08 cm. The formed and stapled vent is formed into coils or rolls in step 526, for example as shown in Fig. 24 or even more in Fig. 23. The spiral rolls formed in step 526 could be secured in step 528 by placing one or more bands around them. The labels may be affixed to the rolls with bands in step 530. The labeled rolls may be embossed for storage or shipping in step 532. Various modifications of this invention may be made without departing from the spirit of the same. Therefore, the scope of the invention is not limited to the modes illustrated and described. Instead, the scope of the invention should be determined by the appended claims and their equivalents.
