Abstract

A unitary single piece fascia and gutter is extruded from plastic material or a composite and is formed with a relatively flat fascia portion sized to cover the ends of rafters along an edge of a roof. A gutter portion projects upwardly and outwardly from the fascia portion and the gutter portion and fascia portion together bound and define a gutter trough for receiving rainwater and directing the rainwater to a drainage location. The fascia and gutter is installed along an edge of a roof by being positioned along the edge with the fascia portion covering the edge and the gutter portion projecting outwardly from the edge, and securing the fascia and gutter to the edge of the roof with appropriate fasteners.

Description

UNIT PROTECTION AND CANAL CHART Field of the Invention This description generally refers to roof structures and more particularly to the protection board and channels of the roof structures.

Background of the Invention A common residential pitched roof structure has roof decks of a predetermined profile covered with tiles. A common configuration in the lower edge portion of the roof structure is a paneling projection. A vertical protection board panel is usually installed at the end of the projection to cover the ends of the roof beams and to provide a pleasant architectural appearance. It is also common for rain channels to be installed along the protection table. The shingles of the roof deck overlap the protection board and partly protrude over the channels so that the channels collect the rainwater from the roof and direct it to the gutters that supply the water to a location designated for drainage. In the past, channels made of aluminum, copper, plastic, or other material have been manufactured separately, on site or in a remote installation, and installed with fasteners to the protective board panels REF. 215348 of a roof structure. Although this is functional, it nevertheless has certain inherent problems. For example, the manufacture of particular metal channels is slow, expensive, and requires a high degree of specialized skill. The installation of the channels also requires particular skill. In addition, once the channels are installed, they can have water leaks, especially after years of use, and these leaks commonly lead to the decomposition of the protection board panels and the base timber structures. This condition commonly requires that the channels and protection board be removed and replaced with new channels and protection board. Therefore, there is a need for a rain gutter and protection board system that is simple and efficient to install, that requires a lower degree of experience and skill, that eliminates the decomposition leaks from the protection table, and that be economically and architecturally attractive. It is a requirement of such channel system that the present invention is primarily directed.

Brief Description of the Invention A protection board and a unitary channel extruded from a plastic or composite material in predetermined lengths are briefly described. The protection table and channel are outlined to define a portion of substantially flat protection board with a size to cover the beam ends along the edge of a roof. A channel portion of the protection board and channel is extruded unitarily with the protection board portion and extends outwardly and upwardly therefrom so that the protection channel and board together join and define a raceway. The channel portion preferably has an outer profile that mimics that of traditional metal channels, or it may have a unique and different profile if desired. The protection board and channel are installed along the edge of a roof structure with fasteners extending through the protection board portion and toward the ends of the roof beams. When installed, the roof protection table and the channels are applied simultaneously. In addition, the installation requires a significantly lower skill level and significantly less time than the protection table and separate channels of the prior art. No separate manufacturing and installation of the channels and the problems associated with the leaking channels are required and therefore the deteriorated protection board panels are eliminated. At the corners, the protection board and channel can simply be joined together at miter and welded together by, for example, hot welding or sonic welding forming a unitary and hermetic corner. These and other characteristics and advantages of the protection table and channel described will become more evident from the review of the detailed description indicated below when considered in combination with the appended figures, which are briefly described as follows.

Brief Description of the Figures Figure 1 is a sectional view of the edge portion of a roof structure illustrating a protection board and channel installed in accordance with the present disclosure.

Figure 2 is an enlarged cross section of the protection and channel table of this description illustrating a particular embodiment thereof.

Figure 3 is a top plan view of the protection and channel table of this description illustrating two lengths welded together in a corner to form a hermetic joint.

Detailed description of the invention Now with reference more in detail to the figures, in which similar numbers refer to similar parts through several views, Figure 1 is a sectional view of a roof structure 11 constructed with an inclined roof 12 having the beams 13, a Roof cover 14, and roof tiles 16 that cover the roof deck. The beams 13 rest on the upper plate of a wall 21 and, in the illustrated structure, the roof joists 19 define an interior roof of the structure. The beams 13 protrude from the wall 21 and extend to the beam ends 18, which are cut at an angle to define the vertical ends substantially aligned. The protruding portion of the beams and roof 12 define a panel 22 in a traditional manner. Although a traditional gable roof with roof joists, a ledge, and a ceiling light, are illustrated in Figure 1, it should be understood that this is not a limitation of the invention and that the invention can be used with others and different types of roofs and roof structures. For example, the invention can be used with a roof structure that does not protrude from the walls to define the soffits but on the contrary is substantially flush with the exterior walls of a construction.

A table of. unit protection and channel 23 according to the present disclosure is secured to and extends longitudinally and covers the ends 18 of the roof beams 13. The protection board and channel 23 comprises a portion of protection board 24, which is formed with a substantially flat configuration and has a width corresponding to the width of a traditional protection board panel. The thickness of the protection board portion 24 can also be approximately the same as the of a traditional protection board panel, although it can also be thicker or thinner depending on the dictated application requirements. The fasteners 28 are placed through the guard board portion 24 and at the ends 18 of the beams 13 to secure the guard board and channel in place as shown. The fasteners may be nails, screws, staples, or any other appropriate fastener to secure the protection board portion to the beam ends 18. When fastened along the ends of the beams as shown, the table portion Protection 24 mimics the appearance of a traditional protection board panel that can be joined in other ways to define the roof edge protection board.

A channel portion 26 of the protection board and channel 23 is formed unitary with the protection board portion and extends exteriorly and upwardly therefrom. More specifically, the channel portion 26 extends outwardly from near the lower edge of the guard board portion 24 and then upwardly to a flange 33. The outer profile of the channel portion 26 can be formed to mimic the profile of a traditional metal channel as illustrated in figure 1, or, alternatively, it can be formed with other and different shapes as desired or needed. In any case, the channel portion 26 in combination with the protection board portion 24 joins and defines a conduit 27 formed to contain the rainwater and direct it to a drainage location. The tiles 16 of the roof 12 preferably protrude from the upper edge of the protection board portion 18 as illustrated in Figure 1 to direct the rainwater flowing down from the ceiling into the conduit 27, where it is contained in the conduit 27 by the protection board portion defining the rear part of the conduit and the channel portion defining the front part of the conduit. One or more channels 29 can be secured to a corresponding opening formed through the lower part of the conduit to receive the rainwater inside the conduit and direct it downwards to drain it away from the construction.

Figure 2 is a cross-sectional view of a possible mode of the protection table and channel of this description. As mentioned above, the unit protection board and channel 23 are formed with a guard board portion 24 and a channel portion 26. More specifically, the guard board and channel 23 are preferably formed by extruding an appropriate material to provide strength, durability, and appearance to the unit protection and channel table. Such materials can include, for example, a plastic material such as polyvinyl chloride (PVC, its acronym in English), a composite material such as a plastic with organic or inorganic fillers, or other appropriate material. In the exemplary embodiment of Figure 2, the protection board and channel 23 are extruded from a plastic material with a relatively less dense foamed plastic base 31 surrounded by a relatively denser plastic layer 32. This configuration is light, makes the Use of materials, and provides a durable exterior surface that mimics the appearance of traditional metal channels. In addition, the protection board and channel can be extruded from plastics that have a variety of colors to match various designs and decoration schemes, and, contrary to metal channels, the color is indelible and scratch resistant.

The unit protection and channel table of this description offers additional advantages when two lengths are joined in a corner of the roof, where traditional metal channels are joined in an unsightly manner or have a tendency to leak. Figure 3 illustrates the first and second lengths of the protection and channel table of this description that are joined at a right angle and are joined together so as to be in a corner of a roof. More specifically, each length is mitered at its end, in this case at forty-five degrees. The miter-joined ends are then thermally welded together along the splice 34 to form a Hermetic, strong, and unitary connection between the lengths of the protection board and channel. The ends may be welded in any acceptable manner such as, for example, with a heat-welded protection board, plastic welding bars, sonic welder, or the like. In any case, the l junction between Protective board and channel lengths can be formed with the channel portions that are tilted at opposite angles or that are higher or lower in the protection board portion so that the long lengths of the protection board and channel they can be connected end to end while maintaining the inclination of the channel portion or to provide an inclination in any direction. These and other modifications and I Additions can be made well to the illustrated embodiments without departing from the spirit and scope of the invention as set forth in the claims.

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.
