Description

BACKGROUND OF THE INVENTION

1. Field of the Disclosure

The present invention relates in general to outdoor decking and, in particular, to a system, method and apparatus for deck water drainage.

2. Description of the Related Art

Numerous attempts have been made to provide drainage systems for decks to prevent water and debris passing through the deck floorboards from reaching the space beneath the deck. Some of these systems are permanently installed below the deck, creating difficulties when it is necessary to clear away debris that has fallen between deck floorboards into the collection system. Other systems do not provide a level of finished appearance desired for more expensive homes. U.S. Pat. No. 6,226,941, describes a deck drainage system in which water collection panels are not permanently attached to the building structure and which can be cleaned. However, the collection panels span an entire dimension of the deck without intermediate support, and as a result their weight is borne by tubular beams underlying the ends of the panels. This requires relatively complex and expensive manufacture of the components for the system. Other deck drainage systems are described in U.S. Pat. Nos. 6,279,271 and 7,434,358. Improvements in deck drainage systems continue to be of interest.

SUMMARY

Embodiments of a system, method and apparatus for deck drainage are disclosed. For example, a deck drainage system may comprise a plurality of hanger clips. Each hanger clip may have a plurality of mounting holes configured to fasten the hanger clip to a support at selected elevations. A soffit may be mounted to the hanger clips without fasteners and located completely below the deck, such that not every hanger clip directly contacts the soffit. A slope of the soffit may be selected by mounting at least two of the hanger clips to the support at different vertical elevations. The soffit may be configured to slope beneath the deck and drain water therefrom in a selected direction.

Other embodiments of a deck drainage system may comprise a plurality of hanger clips configured to be fastened to a support. Each hanger clip may have a hanger clip rim. A plurality of soffits may be mounted to the hanger clips. Each soffit may have a first rim complementary in shape to the hanger clip rim and configured to mount directly to the hanger clip rim. Each soffit may have a second rim complementary in shape to the first rim and configured to mount directly to the first rim of an adjacent soffit.

Still another embodiment of a deck drainage system may comprise a plurality of hanger clips configured to be fastened to a support. Each hanger clip may have an interior clip and an exterior clip. A soffit may be mounted to the interior clip of a first one of the hanger clips at an interior of the deck. The soffit also may be mounted to the exterior clip of a second one of the hanger clips adjacent an exterior of the deck.

The foregoing and other objects and advantages of these embodiments will be apparent to those of ordinary skill in the art in view of the following detailed description, taken in conjunction with the appended claims and the accompanying drawings.

DETAILED DESCRIPTION

Embodiments of a system, method and apparatus for deck drainage are disclosed. For example, as shown in FIGS. 1 and 2, a deck drainage system 11 may be secured to an outdoor deck 13 to help maintain a dry space below the deck 13. The deck drainage system 11 includes components that capture water that drains through the deck 13 to an under side of the deck 13. In some versions, the deck drainage system 11 may be used in conjunction with a gutter system 15 to guide the drained water to a desired location.

In some embodiments (FIGS. 2-4), the deck drainage system 11 may comprise a plurality of hanger clips 21. Each hanger clip 21 may be provided with having a plurality of mounting holes 23 configured to fasten the hanger clip 21 to a support at selected elevations. The mounting holes 23 may comprise horizontally adjacent pairs of mounting holes 23, as illustrated. In some versions, the adjacent pairs of mounting holes 23 are vertically spaced apart from other ones of the adjacent pairs of mounting holes 23, such as by about 0.5 inch.

Embodiments of the supports to which the hanger clips 21 are mounted may comprise grid bars 27. Grid bars 27 may be attached to deck joists 25, such as with fasteners like screws or nails. Alternatively, the supports may comprise the deck joists 25 themselves, such that the hanger clips 21 are secured or fastened directly to the deck joists 25 without the need or use of grid bars 27. The hanger clips 21 may be fastened only to substantially vertical surfaces of the support, whether the deck joists 25 or the grid bars 27.

As shown in FIGS. 1, 2, 5 and 6, embodiments of the deck drainage system 11 may include soffit 31 mounted to the hanger clips 21. The soffit 31 may be secured to the hanger clips 21 without fasteners, and may be located completely below the deck 13, which may include the deck joists 25 as well. However, in some embodiments, not every hanger clip 21 used to support soffit 31 directly contacts the soffit 31, as will be explained elsewhere herein.

In addition, the soffit 31 may be sloped at a selected angle of inclination to enable water drainage in a selected direction. In some versions, the slope of the soffit 31 may be selected by mounting at least two of the hanger clips 21 to the support at different vertical elevations, such that the soffit is configured to slope beneath the deck and drain water therefrom in a selected direction. Embodiments of the soffit 31 may be located completely below the deck joists 25 of the deck 13, not vertically between the deck joists 25 as is the case with some conventional designs.

Again referring to FIGS. 3 and 4, embodiments of the hanger clips 21 may comprise a body 41 and a mounting portion 43 extending from the body 41. The mounting holes 23 may be formed in the mounting portion 43, in some versions. The mounting portion 43 may be configured to be substantially perpendicular to the body 41. The hanger clips 21 may further comprise reinforcements 45 extending between the body 41 and the mounting portion 43.

Embodiments of the hanger clip 21 may be provided with first and second clips 47, 49, both of which may extend from the body 41. The first clip 47 may be used in a first orientation, and the second clip 49 may be used in a second orientation that is different than the first orientation. The first and second orientations may comprise opposite vertical orientations. For example, the first orientation may be suitable along a perimeter of the drainage system 11 (e.g., hanger clip 21a in FIG. 8), whereas the second orientation may be suitable in an interior of the drainage system 11 (e.g., hanger clips 21b, 21c and 21d in FIG. 8). In some embodiments, the first orientation may be used for the lateral perimeter of the drainage system 11, and the second orientation may be used therebetween.

In some embodiments, each hanger clip 21 may further comprise a pitch gauge 51 that may be configured to assist an installer (e.g., as a visual aid) to adjust the slope of the drainage system 11. As shown in FIG. 3, the vertical span of the pitch gauge 51 (Vpg) may exceed a vertical span of the mounting holes 23 (Vmh). Versions of the pitch gauge 51 may comprise fingers, notches or tabs 53 extending from each hanger clip 21. At least some of the adjacent fingers, notches or tabs 53 may vertically straddle adjacent ones of the mounting holes 23, as shown in FIG. 3.

As depicted in FIGS. 3, 14 and 15, the pitch gauge 51 is configured to be used to selectively position the hanger clip 21 relative to a lower surface of the support (e.g., grid bars 27) to form the slope of the soffit 31 (FIGS. 1 and 16). In FIG. 7, the downward slope of the drainage system is substantially from the lower left of that image to the upper right of that image. Thus, the hanger clips 21 on the lower left (first course 111) are mounted to their support (i.e., grid bar 27) at a highest vertical elevation (e.g., most tabs 53 above grid bar 27) of the drainage system 11. In contrast, the hanger clips 21 on the upper right (course 117) are mounted to their support (i.e., grid bar 27) at a lowest vertical elevation (e.g., no tabs 53 above grid bar 27) of the drainage system 11. The hanger clips 21 located between the highest and lowest vertical elevations (those in the other courses 113, 115) may be carefully graded to gradually reduce the vertical elevation therebetween.

Embodiments of the drainage system 11 may require no shims to form the slope of the soffit 31. However, depending on the levelness of the deck joists 25, some shims may be required between the grid bars 27 and the deck joists 25 to support the grid bars 27 in a level array.

In some versions (see FIGS. 8-11), the hanger clips 21 located along one longitudinal side of the soffit 31 (i.e., the left side of each soffit) directly contact the soffit 31. However, the hanger clips 21 along the other longitudinal side of the soffit 31 (i.e., the right side of each soffit) do not directly contact the soffit 31 but only directly contact adjacent soffit 31. For example, FIG. 9 depicts the right side of soffit 31a and the left side of soffit 31b. Hanger clip 21 only directly contacts (i.e., physically touches) the left side of soffit 31b. Hanger clip 21 does not directly contact (i.e., does not physically touch) the right side of soffit 31a. Thus, hanger clip 21 directly supports soffit 31b but only indirectly supports soffit 31a. This configuration may characterize the deck drainage system 11 as having nested rims with at least two soffits 31.

Other embodiments of an under deck drainage system 11 may comprise a plurality of hanger clips 21 configured to be fastened to a support (e.g., deck joist 25 or grid bar 27). Each hanger clip 21 may be provided with a hanger clip rim (also referred to herein as the second clip 49). A plurality of soffits 31 may be mounted to the hanger clips 21.

Referring again to FIGS. 5, 6 and 9, each soffit 31 may be provided with a first rim 61 that is complementary in shape to the hanger clip rim 49. First rims 61 may be configured to mount directly to the hanger clip rim 49. In addition, each soffit 31 may comprise a second rim 63 that is complementary in shape to the first rim 61 and configured to mount directly to the first rim 61 of an adjacent soffit. Thus, the hanger clip rims 49 on the hanger clips 21 along one longitudinal side of the soffit 31 directly contact the first rims 61 of the soffit 31b (FIG. 9), and the hanger clip rims 49 on the hanger clips 21 along the other longitudinal side of the soffit 31a do not directly contact the soffit 31. In effect, the hanger clip rim 49 nests inside the first rim 61, and the first rim 61 nests inside the second rim 63 of the adjacent soffit 31.

Embodiments of the first and second rims 61, 63 may extend in a same lateral direction (i.e., into and out of the page in FIGS. 8-11). Respective sets of the hanger clip rims 49, first rims 61 and second rims 63, may positively engage each other to form a retention force therebetween. In some versions, the retention force must be overcome to disengage respective sets of the hanger clip rims 21, first rims 61 and second rims 63.

In some examples (e.g., FIGS. 5 and 6), each of the first and second rims 61, 63 may comprise a hook 65 and a tab 67 extending inward therefrom. The hooks 65 and tabs 67 of the first and second rims 61, 63 may be respectively complementary.

Embodiments of the exterior clips 47 may be utilized with soffit 31 by first cutting or removing one of the first or second rims 61, 63 to form a cut end 60. See, e.g., FIGS. 8, 10 and 13. Cut ends 60 essentially comprise only the flat planar body 32 of a soffit 31. Cut ends 60 are received in a slit 48 of exterior clips 47, as shown. Slits 48 snugly grip cut ends 60 such that they are retained by a pinch force.

Embodiments of the hanger clip rim 49 may comprise a flat portion 71 (FIG. 3) extending from the hanger clip 21, and a hook 73 extending from the flat portion 71. The hook 73 may comprise a convex portion 73a that curves from the flat portion 71 toward the hanger clip 21, and a concave portion 73b that curves from the convex portion 73a away from the hanger clip 21.

Embodiments of the soffit 31 may be provided with first and second side walls 81, 83 (FIGS. 5 and 6). The first and second rims 61, 63 may extend from the first and second side walls 81, 83, respectively. In one example, the first side wall 81 may be formed at an acute angle α relative to a body 32 of the soffit 31. The acute angle α may comprise, for example, about 85 degrees +/− about 2 degrees. This acute angle α or taper tends to pre-load the soffits 31 against each other upon installation. Thus, in some embodiments, shapes of the first and second side walls 81, 83 of adjacent connected soffits 31 may be configured to pre-load the adjacent connected soffits 31 against each other. The second side wall 83 may be formed substantially perpendicular to the body 32 of the soffit 31. Body 32 also may comprise decorative or ornamental features, such as edge chamfers 34 (FIG. 5) or beads 36 (FIG. 6), for example.

Still other embodiments of the deck drainage system 11 may comprise a plurality of hanger clips 21 configured to be fastened to a support (e.g., deck joist 25 or grid bar 27). Each hanger clip 21 may be characterized as having an exterior clip 47 (also referred to herein as a first clip), and an interior clip 49 (also referred to herein as a second clip). A soffit 31 may be mounted to the interior clip 49 of a first one of the hanger clips 21 at an interior of the deck 13. In addition, the same or other soffit 31 may be mounted to the exterior clip 47 of a second one of the hanger clips 21 adjacent an exterior of the deck 13. The interior clip 49 may be located on one end of the hanger clip 21. The exterior clip 47 may be located opposite the interior clip 49. A slope of the soffit 31 may be selected by mounting at least two of the hanger clips 21 to the support at different vertical elevations, such that the soffit 31 is sloped to drain water.

Embodiments of the hanger clips 21 may be provided with a vertical series of mounting holes 23. In some versions, at least two of the hanger clips 21 may be mounted to the support via their mounting holes 23 but at different vertical elevations to form the slope of the soffit 31.

Some embodiments of the deck drainage system 11 may further comprise a fascia 91 (FIGS. 12 and 13). The fascia 91 may be configured to be mounted to at least some of the hanger clips 21, such as those around a perimeter or exterior of the deck drainage system 11. The fascia 91 may be provided with an attachment portion 93 that is complementary in shape and secured to the exterior clips 47 of second ones of the hanger clips 21. The attachment portion 93 may comprise a butt end 95 extending from a body 97 of the fascia 91, and a fascia hook 99 extending inwardly from the butt end 95. The butt end 95 may be oriented at an acute angle α with respect to the body 97 of the fascia 91. For example, the acute angle α may comprise about 85 degrees +/− about 2 degrees. This acute angle α or taper tends to pre-load the fascia 91 against the hanger clips 21 upon installation. Thus, in some embodiments, shapes of the first and second side walls 81, 83 of adjacent connected soffits 31 may be configured to pre-load the adjacent connected soffits 31 against each other.

In some embodiments of the deck drainage system 11, the only fasteners required to mount the drainage system 11 to the support are fasteners 101 (e.g., see screws or nails in FIGS. 7, 14 and 15) that secure the hanger clips 21 to the support. No other fasteners may be required. Thus, the hanger clips 21 and soffit 31 are fastenerless such that the interior and exterior clips 47, 49 require no fasteners to secure the soffit 31 thereto.

For example, at higher vertical elevations (FIGS. 7, 14 and 16), such as the first course 111 of hanger clips 21, the lowermost tab 53a of pitch gauge 51 may be aligned with the bottom of the support 27. This allows a fastener 101 to insert through the lowermost mounting hole 23a (and those above it) to secure hanger clip 21 to support 27. At lower vertical elevations (FIG. 15), such as the next course 113 of hanger clips 21, the second lowest tab 53b of pitch gauge 51 may be aligned with the bottom of the support 27. This allows a fastener 101 to insert through the second lowest mounting hole 23b (and those above it) to secure hanger clip 21 to support 27. This process may progress to the next sets of tabs 53 and mounting holes 23 in courses 115 and 117 (FIG. 16). Such a configuration gradually lowers the vertical elevations of the soffit 31 from left to right (i.e., the water flow direction), such that any water collected by deck drainage system 11 may be deposited in gutter system 15 along the right edge thereof.

In addition, note that the hanger clips 21 along the perimeter courses 119 and 121 would be secured to soffit 31 with exterior clips 47, while hanger clips 21 that extend along the interior courses 123 would be secured to soffit 31 with interior clips 49. The exterior clips 47 may be used for soffit connections along a lateral perimeter of the deck drainage system 11. The interior clips 49 may be used for soffit connections in an interior of the deck drainage system 11 other than the lateral perimeter, as shown.

Embodiments of a method of installing a deck drainage system also may be provided. In one version, the method may comprise providing a plurality of hanger clips, each having a plurality of mounting holes; fastening the hanger clips through their mounting holes to a support at different vertical elevations relative to the support to define a slope for a soffit; and then mounting the soffit to the hanger clips without fasteners, such that the soffit is located completely below the deck and is sloped to drain water therefrom in a selected direction.

Another embodiment of a method of installing a deck drainage system may comprise fastening a plurality of hanger clips to a support, each hanger clip having a hanger clip rim; providing a plurality of soffits, each having a first rim complementary in shape to the hanger clip rim, and a second rim complementary in shape to the first rim; and then mounting the soffits to the hanger clips by mounting the first rims directly to the hanger clip rims and mounting the second rims directly to the first rims of adjacent soffits.

Still another embodiment of a method of installing a deck drainage system may comprise fastening a plurality of hanger clips to a support, each hanger clip having an interior clip and an exterior clip; and then mounting a soffit to the interior clip of a first one of the hanger clips at an interior of the deck, and to the exterior clip of a second one of the hanger clips adjacent an exterior of the deck.
