Description
- This application claims the benefit of U.S. Provisional Application No. 61/802,048, filed Mar. 15, 2013, and U.S. Provisional Application No. 61/878,248, filed Sep. 16, 2013.
- The invention relates generally to a system configured to facilitate drainage from the floor of a screened porch, lanai, pool cage, or other screened enclosure.
- Property owners often enclose a porch, lanai, pool, or other area with mesh screen for protection against insects and/or other pests. Screened enclosures can collect rain water. In addition, water might also collect on the floor of an enclosure from a pool, fountain, or other water feature within the enclosure. Conventional screen framing can trap such water inside the enclosure, which can lead to unhealthy and unsightly mold growth.
- Many times, property owners do not anticipate installing a screened enclosure. Accordingly, drainage provisions may not exist, for instance, in the original slab of a porch or patio. Moreover, it may be cost prohibitive to add a trench or other drainage system to a pre-existing concrete slab. For these and other reasons, an inexpensive and effective system is needed to facilitate drainage from the floor of a screened enclosure.
- Embodiments of the invention solve one or more of the shortcomings described above by modifying a floor member of a screened enclosure wall frame to include at least one drainage channel. The drainage channel facilitates drainage (typically of water from inside the screened enclosure to outside the screened enclosure), while also providing a barrier to insects and other pests. In a first embodiment, the drainage channel includes gate openings and corresponding gates disposed directly onto each side of a floor member of a screen frame. A variant of the first embodiment includes a weeping slot on at least one side of the drainage channel. In second and third embodiments, a section of the floor member is replaced with a drain insert. A drainage channel in the drain insert may include one or more gate openings and associated gates. The drainage channel in the drain insert may also include one or more weeping slots. In variants of the second or third embodiments, the body of the drain insert is configured as a two-part assembly to facilitate the plastic molding of one or more spline grooves in the drain insert.
