Description

BACKGROUND

1. Field of the Disclosure
The disclosure relates generally to a gutter for directing rainwater and debris from a roof of a structure, and more particularly, to a gutter assembly including an inner channel for directing the flow of rainwater and debris and an outer channel for creating an aesthetically pleasing appearance.
2. Description of the Related Art
Typically, the roofs of homes and other buildings have rain gutters or eaves troughs hung on the outer edge of the eaves below the roof line to catch and redirect rainwater flowing down from the roof. The gutters receive and redirect the flow of water into a downspout which carries the water to the ground.
A common problem with rain gutters and downspouts is that leaves, branches, pine needles and other debris often collect and accumulate within the gutters and downspouts, clogging them and preventing water from flowing through the gutters and into the downspouts. Also, when water from rain or melting snow flows down the roof, the debris on the roof is carried into the gutters and downspouts, clogging them both. If the gutters or downspouts are clogged, the gutters overflow onto the ground possibly causing soil erosion and/or damage to the building's foundation.
In the prior art, devices have been developed to attempt to prevent the clogging of gutters and downspouts. These devices include screens, sieve devices and liners, which all work under the same principles of keeping debris out of the gutter while allowing water to flow into the gutter. However, in many cases, leaves and debris get caught in the above-mentioned devices restricting or preventing water from entering the gutter. In this situation, water may back up under the roof shingles and cause damage to the roof sheathing or fascia board. This condition may be further compounded in winter weather where ice and snow may develop on the clogged device causing stress on the gutter support from the added weight or may cause the formation of an ice dam from the collection of water. Additionally, these devices require period cleaning to remove the debris lodged in them.
Furthermore, during installation, gutters are typically mounted with a pitch to allow water to flow to one end. However, by sloping the gutter, a portion of the fascia board is exposed and over time damage will result. Furthermore, the sloping of the gutter results in an unsightly appearance to the building.
Therefore, a need exists for a gutter system which facilitates the flow of water and debris from a building structure while maintaining its appearance. A further need exists for a gutter system which requires no cleaning or maintenance.

SUMMARY

A gutter assembly and method for making same are provided. The gutter assembly includes an inner channel for directing flow of water and debris; and an outer channel for supporting the inner channel, wherein the inner channel is disposed within the outer channel at a predetermined angle. The gutter assembly of the present disclosure facilitates the removal of water and debris from the roof of a building structure while protecting the structure and maintaining an aesthetically pleasing appearance.
In one aspect of the present disclosure, a gutter assembly is provided including an inner channel for directing flow of water and debris; and an outer channel for supporting the inner channel, wherein the inner channel is disposed within the outer channel at a predetermined angle. The inner channel has a substantially arcuate cross-section and the outer channel includes a front face, a bottom wall and a back wall, wherein the back wall is coupled to a structure for supporting the assembly.
In another aspect, the inner channel and outer channel are integrally formed from a flat sheet of material. Furthermore, the inner channel and outer channel may be formed from sheet metal, aluminum, plastic or vinyl.
In a further aspect of the present disclosure, the gutter assembly may include a heating mechanism disposed between the inner channel and outer channel.

DETAILED DESCRIPTION

Preferred embodiments of the present disclosure will be described hereinbelow with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail to avoid obscuring the invention in unnecessary detail. Throughout the drawings, like reference numerals represent like elements.
A gutter assembly and method for making same are provided. The gutter assembly of the present disclosure facilitates the removal of water and debris from the roof of a building structure while protecting the structure and maintaining an aesthetically pleasing appearance.
FIG. 1 is a perspective view of a gutter assembly attached to the outer edge of an eaves surrounding a building in accordance with the present disclosure. The gutter assembly 10 includes an inner channel 12 for directing the flow of water and debris received from a roof and an outer channel 14 for supporting the inner channel 12. As can be seen from FIG. 2, the inner channel 12 is disposed within the outer channel 14 at a predetermined angle, or pitch, to direct the flow of water and debris to a downspout 16. The predetermined angle of the inner channel 12 eliminates the need to slope the entire gutter assembly and allows the outer channel 14 to be placed flush with the roof line and level to the ground. In this manner, the fascia board 24 of the building is not exposed to weather thus preventing damage, e.g., wood rot. Additionally, since the gutter assembly of the present disclosure is not manually sloped by an installer, installation time is reduced, and therefore, installation cost is reduced.
Referring to FIG. 3A, a cross-sectional view of the gutter assembly 10 is illustrated. The inner channel 12 has a substantially arcuate cross-section for facilitating the flow of water and debris; flat bottomed gutters have the tendency to retard water flow due to the increased coefficient of friction of the broader surface area. As can be seen in FIGS. 3B and 3C, the inner channel 12 will be sloped to direct the flow of water. Preferably, the angle or pitch of the inner channel 12 will be determined based on a length L of the gutter assembly section. Each section of the gutter assembly includes an upstream end 26 and a downstream end 28. When determining the angle of the inner channel 12, the upstream end 26 will include a minimum height h1 between the inner channel 12 and an upper edge of the outer channel 14 to ensure a passage is created for the collection of water and debris. Furthermore, a maximum height h2 will be incorporated on the downstream end 28. Height h2 will depend on how many sections of the gutter assembly are used in a particular run, the details of which will be described below.
The outer channel 14 is generally U-shaped and includes a front face 18, a bottom wall 20, and a back wall 22. It is to be appreciated that front face 18 may be of any configuration and is not limited to the configuration shown throughout the figures. Back wall 22 is generally planar to mate flush with fascia board 24 of the building structure.
In one embodiment, the back wall 22 of outer channel 14 includes an elongated edge 30 which will be bent over one edge 32 of the inner channel 12 securing the inner channel to the outer channel 14 and for forming a nailing strip 34. A fastener 36, e.g., a self-tapping screw, may then be driven through edge 30 piercing the inner channel 12 and back wall 22 securing the gutter assembly 10 to the fascia board 24. In another embodiment, front face 18 includes a second elongated edge 38 which will be bent over a second edge 40 of the inner channel 12 to prevent water and debris from entering a passageway 42 between the inner channel 12 and the outer channel 14. Preferably, the second edge 40 of the inner channel 12 will be fastened to the outer channel, e.g., by crimping, welding, etc., to further support the inner channel 12. Once secured to the fascia board 24 via the nailing strip 34, the inner channel will support the outer channel obviating the need for long nails to penetrate the front face 18 and the back wall 24 as in conventional gutters.
In one embodiment, the gutter assembly will be manufactured in sections. Referring to FIGS. 4A and B, a first gutter assembly section 10-1 and second gutter assembly section 10-2 are shown in an exploded view. In this embodiment, each of the first and second gutter assembly sections 10-1, 10-2 are constructed with a length of the inner channel 112 longer than a length of the outer channel 114. In this manner, the first and second gutter assembly sections 10-1, 10-2 will telescopically mate to form a single length of the gutter assembly. The first gutter assembly section 10-1 will include an outer channel 114-1 as described above and an inner channel 112-1 angled within the outer channel 114-1. Here, the maximum distance h2 of the down stream end will be set to accommodate the mating of the inner channel with additional gutter assemblies. The second gutter assembly section 10-2 will includes an outer channel 114-2 as described above and having the sane dimensions as outer channel 114-1 so when mated together the gutter assembly will appear to be a single continuous piece. The inner channel 112-2 of the second gutter assembly section 10-2 will have a large minimum distance h1 on the upstream side as to telescopically mate with the inner channel 112-1 of the first gutter assembly section 10-1. Once mated, the downstream end of inner channel 112-1 will lie in contact with the upstream end of inner channel 112-2. Optionally, a back flow prevention device 44 may be installed where the inner channels meet. For example, the back flow prevention device 44 may be a rubber gasket, a small amount of silicon or any other known device or material which is water-proof. It is to be appreciated that the length of a gutter assembly section should not be limited to any particular length but may be prefabricated in a variety of lengths so in combination may achieve a desired length of an installer.
Referring to FIG. 5, a gutter system 200 embodying the principles of the present disclosure is illustrated. Gutter system 200 includes at least one gutter assembly 10, an end cap 246, an end piece 248 and a downspout 250. In operation, water from rain, melting snow etc, and debris would run down the roof into the inner channel of the gutter assembly 10 and would flow in the direction as indicated by the arrows. The water and debris would discharge into the end piece 248, down the downspout 250 and carried away from the building.
Referring to FIGS. 6A and 6B, several embodiments of an end piece according to the present disclosure are shown. Each of the end pieces 248-1, 248-2 are formed with a plurality of pieces having compound angles forming a funnel-like effect. End piece 248-1 includes a first half 252 and a second half 254 symmetrically formed about a spout 256. Preferably, first and second halves 252, 254 will have a substantially arcuate shape to telescopically mate with a downstream end of an inner channel of a gutter assembly as illustrated in FIGS. 6C and 6D. End piece 248-2 includes a first end piece 258, a second end piece 260, a first side piece 262 and a second side piece 264. Similarly to end piece 248-1, the first and second end pieces 258, 260 will preferably have a substantially arcuate shape to telescopically mate with a downstream end of an inner channel of a gutter assembly. It is to be appreciated that both embodiments of the end piece 248-1, 248-2 will have a funnel-like effect and will facilitate the removal of water from the gutter assembly.
The gutter system may further include a connector or elbow 268 for coupling the end piece 248 to the downspout 250. The connector 268 is illustrates in FIGS. 7A through 7D. Referring to FIG. 7A, the connector 268 includes a coupling section 270 for coupling the connector to the spout 256 of the end piece 248. The coupling section 270 will have a circumference slightly larger than the circumference of the spout 256 to ensure a snug fit and no leakage. The connector 268 will further include a plurality of rigid sections 272, 274, 276, 278 wherein each rigid section is coupled to the next rigid section by a flexible member 280. Preferably, each rigid section is generally cylindrical with a top and bottom cut at an angle. The flexible member may be some form of circular rubber gasket, pliable sheetmetal, etc. As can be seen from FIGS. 7B-7D, the connector 268 can take on virtually any shape by twisting an appropriate rigid section as indicated by the arrows.
It is to be appreciated by those skilled in the art that the gutter assembly and system described herein can be constructed of any commonly used materials including sheet metal, aluminum, plastic or vinyl.
In one embodiment, the inner and outer channel of the gutter assembly are manufactured as two separate pieces using conventional sheet metal forming machines employing rollers and bending mechanisms. The two separate pieces are then joined together as described above by crimping, welding, etc.
In another embodiment, the inner and outer channels of the gutter assembly are integrally formed from a single flat sheet of material. Referring to FIG. 8, a method for forming a gutter assembly from a single sheet of material is illustrated. It is to be appreciated that the method is performed by a specially adapted gutter forming machine. Initially, a single flat piece of material 800, e.g., sheet metal, aluminum, etc., is provided (step a) having a first half 802 and a second half 804 divided by a longitudinal axis 806. A series of rollers 808, 810, 812, 814 interact with the sheet material 800. Rollers 808 and 810 interact with the first half 802 of the material 800 to form the outer channel of the gutter assembly and rollers 812 and 814 interact with the second half 804 to form the inner channel (step b). Once the inner and outer channels 12, 14 are formed, the inner channel 12 is folded over and into the outer channel 14 completing the gutter assembly 10.
In a further embodiment, the gutter assembly is extruded from plastic as a single unitary piece.
In still a further embodiment, the various components of the gutter assembly and system are manufactured from conventional polyvinyl chloride (PVC) type components. PVC should be understood to include all analogous materials, including, but not limited to: CPVC, PVCA, PVCCA, PVCV and PCWC. All such materials must have characteristics permitting a fusion of the materials together upon application of any commercially available PVC liquid fusion compounds, in a chemical welding process, to thereby form a single integrated unit after the parts have been chemically welded together. The liquid fusion compound actually fuses all of the components together into a single integrated piece. Thus, no cracks or leaks are possible because of this weld between the various components. This connection method also enhances the stability and structural integrity of the entire gutter system to increase its self-supporting characteristics.
The gutter assembly and system of the present disclosure may further include a heating mechanism disposed in the passageway 42 between the inner channel 12 and outer channel 14. An exemplary heating mechanism would be a heat trace cable 282 (FIG. 3C) as commercially available from Nelson Heat Trace of East Granby, Conn. The heating mechanism will keep the gutter assembly above a predetermined temperature limit, e.g. 32 degrees F., to prevent the formation of ice or accumulation of snow. The heating mechanism may be activated by a switch located inside the building or may be activated automatically by a thermostat or low limit temperature device located external to the building. Since the heating mechanism will be disposed in the passageway 42, the heating mechanism will be protected from weather and water, thereby preventing a possible short.
A gutter assembly, system and method for making the same has been described. The gutter assembly including an inner and outer channel will facilitate the removal of water and debris from a building structure while maintaining an aesthetically pleasing appearance. Since the inner channel of the gutter assembly is sloped, the outer channel may be installed flush to the roof line thus protecting the structural integrity of the building. Furthermore, since the gutter assembly does not have to be installed with a slope, the gutter assembly can be installed more quickly than conventional gutters thereby reducing installation time and costs.
While the disclosure has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims.
