BACKGROUND OF THE INVENTION

The invention relates generally to home improvements and in particular to a deck drainage system. Homeowners have discovered the many benefits of building a deck, to add recreational living space and value to the home. Unfortunately, in most cases a large space is created beneath the deck that cannot be used, and may eventually provide a home for a stray dog or wild animal, such as a skunk or raccoon. Water seeping through the deck on rainy days, and when snow and ice are melting, prevent the space from being reclaimed by the homeowner for storage.
A search of the prior art reveals various attachments which have been developed to drain away rainwater and melted snow and ice from the surface of a deck. None are closely related to the present invention, but several include features which resemble those of the present invention. Each has proven to be less than satisfactory in its own way. In many densely populated urban areas, space is at a premium and prior art drainage systems generally protrude outward along the entire edge of the deck, creating an obstruction if the deck is located next to a sidewalk or driveway. The present invention has been developed for the purpose of addressing and resolving these disadvantages. A deck drainage system, which redirects the water seeping through the deck into a rain gutter and is located within unused space between the joists, would resolve these problems.
Under deck drainage system, U.S. Pat. No. 8,245,451 (priority Jan. 17, 2008), provides an under deck drainage system for use with a deck. The system includes at least one starter strip mounted to one or more joists of the deck, and a plurality of clips coupled with the starter strip, where the clips are slidable along the starter strip. The system further includes an elongated channel member coupled with at least one of the plurality of clips, and the elongate channel member has at least one channel therein.
Ventilated deck drainage systems, U.S. Pat. No. 8,082,712 (priority Dec. 12, 2005), provides a system and method for providing a deck drain vent system. The deck drain vent system includes at least one panel disposed below a lower surface of a deck. The panel is substantially planar and has a bottom side and a top side facing and spaced apart from the lower surface. At least one vent penetrates the panel to allow fluid communication between the cavity and the bottom side. The deck drain vent system further includes a shaft lock secured to the vent. The shaft lock hinders liquids and debris from entering the vent, yet allows air to freely circulate between the cavity and a surrounding atmosphere.
Modular deck drainage system, U.S. Pat. No. 6,886,302 (priority Aug. 22, 2002), provides a deck drainage system having a plurality of channeled drainage panels. The drainage panels are mounted to direct water flow transversely of the deck joists to a gutter, the panels connected to and suspended from the underside of the joists. The gutter is mounted transversely across the discharge ends of the drainage panels to collect water therefrom and direct it to a down spout. Drainage panels, which are rectangular with the individual drainage channels extending lengthwise, may be overlapped both lengthwise and widthwise to fit the perimeter of the deck.
Deck drain, U.S. Pat. No. 6,792,723 (priority Dec. 13, 2001), provides a deck drain which is manufactured from extruded plastic, with a cross section defining a substantially cylindrical main channel, a mid section, and a top section having a top face with a plurality of openings defined therein. Nail guiding means are attached to the mid section, and direct a nail or screw through the mid section to secure the deck drain to contact the planar surface without wobbling when attached.
Drainage system for decks, U.S. Pat. No. 5,511,351 (priority Sep. 29, 1993), and Drainage system for decks, U.S. Pat. No. 5,765,328 (priority Sep. 29, 1993), provide a deck assembly made of flexible material and mounted beneath the surface decking between adjacent drainage system is designed to collect water leaking through the spaces between adjacent deck dry. The drainage system consists of a plurality of water channeling members respectively formed from substantially flexible web material mounted side-by-side in succession and mounted in an overlapping relationship, straddling adjacent deck joists from view.
