Description

CEILING FAN FOR ROOF TILES BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to roof tile fans having undulating configurations. More particularly, the invention relates to ceiling tile fans used in ceilings having shingle roofs of metallic or ceramic material. 2. Reported Progress The fans for the attics of the buildings are perforated or deflected ventilation openings on the underside of the eaves of a cantilevered ceiling or fascia and on the roof ridge that covers the open roof along the length of the roof . The ventilation openings allow external air to flow into the attic to match the temperature and pressure of the interior attic with that of the external environment. This equalization helps to prevent the degradation of the roof structure, reduces the accumulation of condensation in the insulating material that covers the roof of the attic, which increases the Ref: 128889 efficiency of the heating / cooling of the active space in the building covered by the roof structure. The prior art fan system is typically one comprising: a fan for the roof ridge and a soffit fan or soffit. The ceiling ridge fan covers the open roof along the length of the roof to let air out from the space below the ceiling and the ceiling or ceiling of the attic, that is, when the air that enters the attic through the fan of the soffit or intrados is mixed with the warmer air in the attic, it has to be expelled through an opening in the roof ridge where the warmer, lighter air accumulates. Desirably, the volume of air admitted through the soffit fan or soffit must be balanced or balanced by the volume of air escaping through the fan of the roof ridge. In an optimal ceiling fan / ceiling fan or ceiling fan system, there is a balance between the net free open area presented by such a system. The terminology "Net Free Open Area" or NFA means the cross-sectional area of a fan system which is open for the passage of air through it. This balance or balance of the net free open area of a ceiling or ceiling fan and rooftop ridge fan is difficult to achieve. Thus, in many existing and recently constructed buildings, there will be a tendency for a ventilation system of the roof ridge / panel to be out of balance or balance. Ventilation systems must also prevent insects from entering the attic space of buildings. Although large perforations in the ventilation panels of the roof ridge and ceiling could achieve the desired flow of air through the attic space, they could also allow insects to enter the colonies to form insect colonies. In addition to having good ventilation of the attic space and preventing the entry of water, snow and insects into the attic space, the longing in a ventilation system includes: strength and structural stability to resist the effects of the elements, such as like the strong wind; strong structural support against sagging or warping, such as by the accumulation of snow or ice or by the weight of installers who accidentally step on the ceiling ridge fan; easy handling during installation; and low costs. In ceiling ridge fans designed for use over heavy roof tiles made of slate, terracotta, concrete, clay and metals, roof ridge fan has to withstand heavy roof ridge tiles in addition to snow and the ice that accumulate on the roof. The present invention is directed to roof tile fans which are preferably used in conjunction with a ceiling fan or ceiling suitable for the prior art. Illustrative examples of the prior art directed to the fans for the roof ridge are as follows. The U.S. Patent No. 5, 326,318 describes a fan for the roof ridge for use with heavy roof tiles. The fan comprises an elongated metal support element formed with a beam of hollow rectangular section with the bottom of the beam open and the skirt sections flared therefrom at the inclined angle of the roof. The shape of the support element includes: a) a lid element that anchors or fixes and supports the portion running along the top of the hollow beam; b) two longitudinally oriented side walls containing ventilation openings therein, each wall connected to and vertically downwardly dependent on the support portion; and c) two longitudinally oriented skirt portions that conform to the slope or inclination of the roof. The lid element and the side walls define a longitudinally oriented channel which contains an air permeable material. The ventilation air passes through the air permeable material and out of the ventilation openings. WO 93/04323 discloses a fan for the roof of a synthetic fiber mat constructed of randomly oriented synthetic fibers. In one embodiment for use with heavier terracotta or shale tiles, the mat includes a grid configuration of the solid cores extending across the thickness of the mat. The mat is cut to the length of a roll or cylinder and installed on the groove of the ridge, with the tiles or shingles of crowning or top placement fixed with nails on top of it. The U.S. patent No. 5,651,734 discloses a fan for the roof of the ridge cap applied in the form of a roller or cylinder comprising a material of a sheet of corrugated plastic. The U.S. Patent No. 4,676,147 refers to a roof ridge fan comprising: a one-piece roof element including a pair of fins and a hinge or unitary joint with skirts or fins to allow installation of the fan over the roof ridge from different angles. The fans are located on the flaps or fins. The fans also have an internal deflector structure to deflect the air flow and to limit the entry of foreign particles through the roof ridge. The U.S. Patent No. 4,280,399 discloses a ceiling fan comprising a corrugated plastic sheet material which can be transversely mounted through any ceiling ridge regardless of its roof contours or angles. The U.S. Patent No. 5,457,920 discloses a top roof ridge fan, such a fan includes grill portions flexibly located longitudinally along the side edges. The portions of the grill has at its far end a set of flexible teeth adapted to fit on the shingles and descending between the shingles in the gaps between them, to prevent the passage between the grills and shingles of any debris, insects or vermin. The U.S. Patent No. 4,817,506 discloses a ceiling fan which includes a cover similar to a blade having an inverted V-shaped cross section. A pair of baffles are placed on the lower surface of the cover and include a plurality of spaced apart divisions to support the baffles rigidly against the cover. The U.S. Patent No. 5,095,810 discloses a ventilation system for the roof ridge comprising: a ridge fan composed of two panel portions joined together and forming an inverted V-shaped configuration which fits over the top of the roof. A plurality of V-shaped baffles support the panels. Ventilation flanges are included, which extend downward from each side of the panels to allow air to pass in and out of the openings in the roof. An angled projection is also provided on both sides of the ridge fan to deflect the air up and over the roof to create a negative air pressure which in turn helps to bring out the stagnant air from the attic space. The U.S. Patent No. 5,458,538 discloses a ceiling fan comprising a one-piece plastic body. A plurality of transverse supports are provided for the one-piece plastic body. The system includes a wall to divert the entrance of snow and rain. There are also drainage openings that allow moisture to escape. Although the previous technique has provided several ventilation systems to try to materialize this desire, it has been found that the balance or balance of the Net Free Open Area for a ceiling fan and the roof ridge fan has not been achieved very adequately because the fans for the ceiling ridge do not allow the passage of sufficient quantities of attic air through it, while preventing the entry of snow, rain, ice and insects. Ceiling ridge fans designed for use with tile roofing and having an air permeable fan material such as water and insect barriers, tend to be compressed by heavy roof shingles thus providing a limited air circulation. Support structures to prevent compression or crushing of air permeable material are expensive and difficult to install. The present invention is directed to solve these problems in the fan for the roof of tiles, which is preferably used in conjunction with a fan system ceiling or ceiling of the prior art.

BRIEF DESCRIPTION OF THE INVENTION The present invention is directed to a roof tile fan for use in the ventilation of a building having a sloping roof which has an opening extending longitudinally in its portion of the ridge. The angle that determines the slope or inclination can vary from 20 ° of a "relatively flat roof" to 45-60 ° of a steep roof. Such variation in slope angle or inclination is influenced by construction style, roof size and environmental conditions. A roof of tiles comprises sinusoidal tiles, such as the semicircular or S-shaped roof tiles deposited in rows that extend across the slope of the roof from the lower edge of the roof towards the roof ridge. The rows are deposited in an inverted position and alternately superimposed in a related manner to form an undulating sequence of ridges and valleys extending from the lower edge of the roof towards the roof ridge. The valleys serve as channels to drive precipitation down from the ridge to the lower edge of the roof. The upper row of the tiles are omitted on each side of the ridge to create a hole or opening in the ridge to provide air ventilation from the attic space. This hole or opening will be covered by a roof tile fan to prevent entry of moisture and insects. The present roof tile fan is placed on the upper row of tiles on each side of the ridge to cover the hole or opening in the ridge. The fan profile for the tile roof assumes the same undulating configuration as the upper row of tiles on each side of the ridge. Because of the conformation to the configuration of the tile row, the roof tile fan of the present invention has a low profile and is hardly visible from a distance. The roof tile fan comprises: a) two hard plastic sheets or panels each having a top surface and a bottom surface, comprising a flat portion and an angled portion; b) a fibrous, air permeable mat fixed to the lower surface of the flat portion of each of the hard plastic sheets; and optionally c) a foamed rubber layer attached to each of the fibrous air-permeable mats.

The two hard plastic sheets or panels are mirror images of each other when placed over the hole or opening of the roof ridge. The reference made to one of them is also relevant for the other. The interstices of the fibrous, air-permeable mat are small enough to prevent insects from entering through the mat. The fibrous mat and the foamed rubber layer can be fixed to the hard plastic sheet at the moment of manufacture of the fan for the roof of tiles or they can be placed on the tiles at the work site followed by the placement of the hard plastic sheet on them. In any case, the fixing is preferably by the use of a thermoplastic or adhesive material known in the construction industry. The hard plastic sheet has an angled configuration with an obtuse angle. The flat portion, which has the air-permeable mat and the foamed rubber layer on the lower surface or the lower side, is designed to be placed on the upper row of the undulating tiles on each side of the ridge, while the angled portion points upward at an angle greater than 90 ° but less than 180 °, and preferably at an angle of approximately 110 ° to 140 °. The angled portions of the roof tile fan when installed, serve as a chimney that helps circulate air from the attic space to the outside. The sheet or panel of hard plastic is provided with a plurality of ventilation holes on the portion of the profile thereof, the holes that extend in rows parallel to the edge of the panel. The flat portion of the panel is also provided with reinforcements which are dome-shaped and point upwards from the upper surface of the panel and extend in rows parallel to the roof ridge. The rigidity devices serve as reinforcements on the panel in the support of the ridge tiles placed on the roof tile fan. The method of installing the roof tile fan of the present invention comprises the steps of: a) installing sinusoidal tiles such as semicircular or S-shaped tiles in the rows extending across the roof slope from the edge bottom of the roof towards the ridge of the roof, omitting the upper row of the tiles on each side of the ridge, where the rows of the sinusoidal tiles such as the semicircular or S-shaped tiles are being deposited in an inverted and overlapping position , alternatives, in between, to form a wave-like sequence of ridges and valleys extending from the lower edge of the roof towards the roof ridge, the valleys serve as channels to drive precipitation down from the ridge to the lower edge of the roof; b) place two unitary panels over the opening in the ridgepole so that the lower portions of the panels rest on the uppermost rows of the undulating roof tiles and their crests and valleys conform to those of the roof tiles, and establish a space between the two panels; c) fixing the lower portions of the panels to the ceiling by means of adhesive means or fasteners; d) place the ridge tiles on the roof tiles so that: 1) the ridge tiles are aligned longitudinally on the roof tile fan; 2) ridge tiles are supported by the gallery or ridge board, and the leading edge of the ridge tile rests on the front edge of the roof tile fan; and 3) the ridge tiles are spaced from the angled portions of the hard plastic sheets to form a gap therebetween and thereby allow air to circulate in the space enclosed by the tile roof fan and the ridge tiles; And e) fix the ridge shingles to the roof tile fan and the underlying sloped roof by the use of adhesives or fasteners.

DETAILED DESCRIPTION OF THE INVENTION Figure 1 is a cross-sectional view of a portion of a roof ridge showing a fan mode for the roof of tiles of the present invention designated generally as 10. The fan for the roof of tiles is described in relation to the roof inclined 12 and 12 ', covered with metal or ceramic tiles such as terracotta tiles 14 and 14' of generally semicircular or S-shaped shape and superimposed on each other. The overlapping tiles form ridges and valleys which are parallel to the slope of the roof that directs the flow of precipitation from the roof ridge down to a channel. The crests and valleys form a characteristic undulating sequence of the roof tiles. The inclined roof 12 and 12 'comprises: a gallery 18 of the ridge or ridge to which the rafters are fixed by means of nails (not shown) or other suitable means; a floor or parquet of plywood 20 and 20 '; and the roof tiles 14 and 14 'rest on the floor in a superposed relation to each other. The plywood floor and the roofing shingles on the plywood floor do not completely cover the roof 12 and 12 '; in the ridge or roof ridge there are gaps or ventilation slots designated by the numbers 22 and 22 'which serve as outlets for the air in the attic space 24. There are gaps between each pair of rafters that define a continuous space under the top of the roof so that the attic air can be ventilated to the outside. Although the holes could provide maximum ventilation of the attic space, it could drag rain, snow, insects and debris into the attic space. To prevent such entry, as is well known in the art, a ridge fan or ridge cap covers the voids and overlaps at least partially on the plywood floor and the roof tiles. The overlap ensures that precipitation does not migrate to the top of the roof and into the attic space. The ridge or ridge of the roof above the ridge fan is covered by ridge tiles 26 or for voids.

The roof tile fan 10 of the present invention covers the voids at the top of the roof and provides adequate ventilation of the attic space 24 while preventing the entry of moisture, birds and insects therein. without substantially affecting the maximum ventilation capacity of the holes if they are left uncovered. The fan for the roof of tiles 10 is secured to the gallery 18 of the ridge by the nails 16 for the roof or other securing means. East, and other aspects of the roof tile fan will be explained when the description of the roof is continued. The present invention will be described in relation to the undulating rows of tiles of the ceramic material, such as terracotta tiles, as the preferred roof covering material. However, the invention can be practiced in conjunction with other undulating rows of tiles, panels or shingles made of synthetic material, wood, and a metal such as steel, aluminum and copper. These metal roofs are typically coated with amber granules extracted from mines and with a final paint coating of polymeric materials. The granules and / or the coating of the final paint can be of various colors. Copper is the most respected and economical roofing material that has many advantages over other roofing materials. The same when subjected to the action of the environment develops a nice green patina which protects the surface from further oxidation. The same is lightweight; it cools faster on summer nights, while regular asphalt shingles retain much more heat. The copper and aluminum roofs are made of recycled materials and are therefore environmentally desirable. Terracotta tiles are preferred because of their insulating properties of the roof and their relatively low cost. Figure 2 shows the profile of the fan for the roof of tiles 10 in a fragmentary lateral elevation view extended on the roof tiles 14 and 14 'of the inclined roof. The roof tiles, as shown, are in a configuration of partial overlap with each other. The roof tile fan placed on the roof tiles at its front edge facing the gallery or ridge board comprises: a mat of fibrous material 28 which is integral with the hard plastic panel 32; and optionally, a thin foam rubber sheet 30 on the underside of the mat of the fibrous material as shown in the side elevation view in Figure 3.

The fibrous material forming the mat 28 is made of air-permeable fibers, synthetic, randomly oriented, with variable mesh sizes. Synthetic fibers, such as those made of nylon and polyester, are randomly aligned in a web or network. The weft is cured or hardened in an oven to join the tissues in a mat having interstices in it to allow air to flow through it. Polymeric materials for bonding synthetic fibers together include polyester elastomers, ethylene methacrylate, ethylene vinyl acetate, ethylene vinyl alcohol, polyethylene and polypropylene. The average diameter of the interstices between the randomly oriented fibers can be from about 0.2 mm to about 5 mm and preferably about 1 mm. The thickness of the mat is typically made from approximately 1.27 cm (0.5 inches) to 7.62 cm (3 inches). The air permeable mat is cut into strips, the length and width of which is determined by the length and width of the fan for the roof of tiles in which the strip will be used. The preferred polymeric material for bonding synthetic fibers is polyvinyl chloride. The U.S. Patent No. 5,167,579 discloses an air permeable elastic material which is used in the fan for the ridge cap which is incorporated herein for reference.

The hard plastic panels 32 and 32 'are made of well-known polymeric materials which include polyvinyl chloride, polyethylene and polypropylene. The foamed rubber sheet 30 may be foam of open or closed cells of elastomeric materials. Elastomeric materials for sheet construction include: natural rubber; the acrylate-butadiene rubber; the cis-polybutadiene; chlorobutyl rubber; the chlorinated polyethylene elastomers; the polyalkylene oxide polymers; ethylene vinyl acetate; fluorosilicone rubbers; tetrafluoroethylene fluoride hexafluoropropylene-vinyl diene terpolymers, such as those sold under the trade names of Fluorel and Viton; butyl rubbers; the polyisobutene, such as that sold under the registered name Vistanex; the synthetic polyisoprene rubber; silicone rubbers; styrene-butadiene rubbers; the tetrafluoroethylene propylene copolymers; and the thermoplastic copolyesters.

Figure 3 is a side elevation view of the fibrous mat 28, the foamed rubber 30, and the hard plastic panel 32. The exemplary thickness of the fibrous mat is from about 0.635 cm (0.25") to 5.08 cm (2.0 inches) ), preferably about 1.905 cm (0.75 inches), and the exemplary thickness of the foamed rubber is about 0.635 cm (0.25 inches) to 3.81 cm (1.5 inches), preferably about 1.27 cm (0.5 inches). Typical of the hard plastic panel, the fibrous mat and the foamy rubber taken together is approximately 7.62 cm (3 inches) up to 15.24 cm (6 inches) while the length of the panel is approximately 93.98 cm (37 inches). in the installation they are placed together end to end.At each end of a panel the fibrous mat and the foam rubber are cut to approximately 0.635 cm (0.25 inches) up to 1.27 cm (0.50 inches) so that there is a space overlapped to correspond with two panels that are together end to end. Figure 4 shows a top view of a fan mode for the roof of tiles of the present invention where the number 36 denotes the ventilation holes, the number 34 denotes the reinforcements, the number 38 denotes a flange and the number 40 denotes the spacing of the overlap where the fibrous mat and the foamy rubber are cut. Figures 5 and 6 show the cross sections of the roof tile fan taken along lines 5-5 and 6-6 of Figure 4 respectively. The panel 32 illustrates a left-handed configuration as it could be placed on the ridge or sloped roof ridge 12. The right-hand configuration of the panel 32 is preferably the mirror image of the left hand configuration as best shown in FIG. Figure 1 and the description that follows is relevant for both panels. The panel 32 comprises a lower portion 42 and an upper portion 44. The angle of the upper portion, as shown in Figures 5 and 6, is approximately 120 ° as measured from the lower portion. The angle, however, is determined by the inclination of the roof. It is preferred that the upper portion be generally perpendicular to a horizontal plane. The reinforcements 34 are preferably of a dome-shaped configuration and serve to reinforce the panel against the weight of the tiles 26 of the ridge. The reinforcements run parallel to each other and in the longitudinal direction of the panel. Although in Figures 4-6 three reinforcements are shown, their number can be increased if desired. The panel 32 further comprises the flange 38 which serves to direct the precipitation away from the underlying fibrous mat. The roof tile fan 10 of the present invention can be manufactured in unitary sheets and supplied to the site of the installation. The installation includes the placement of the panels in an end-to-end relationship superimposed on each other and fixing the panels to the gallery or board 18 of the ridge cap by means of screws or nails. The tiles 26 of the cap or ridge are then placed on the roof tile fan, as shown in Figure 1, and secured to the roof tile fan by adhesive means or other means. The air from and within the attic space 24 will be passed through the ventilation holes 36 as well as through the fibrous mat 28 and 28 '. However, the roof tile fan will prevent precipitation and insects from entering the attic space. Figure 7 illustrates another embodiment of the roof tile fan of the present invention in a fragmentary plan view, where two reinforcements 34 are provided. Although there are shown two rows of vent holes 36 similar to that shown in FIG. In the embodiment of Figure 4, a row of the ventilation holes is placed in one of the two reinforcements. The channel covering portions 46, of the panel 32, occupy larger portions with respect to the semicircular, panel-like cover portions 48 of the ridge. This and the similar variations of the respective panel portions allow matching or matching of the underlying roof tiles 14 and 14 'as best seen in Figure 2. The invention having been described with reference to its preferred embodiments, it is to be understood that modifications within the scope of the invention will be apparent to those skilled in the art.

It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention.
