Patent ID: 7574829

Claim:
A combined sliding window assembly and rain draining apparatus, comprising: a building wall of a building having a window opening; a sliding window assembly mounted within said window opening having a window track configured as a channel and windows slidably retained within said window track; a rain draining apparatus comprising a drain conduit having a linking segment extending from and in fluid communication with a window track inside a building, and having an upright segment extending from and in fluid communication with said linking segment and extending below the entirety of said window opening and opening outside the building, said upright segment being in fluid communication with a check valve; and a pressure equalizing vent structure for equalizing air pressure throughout said drain conduit extending from and opening within the building into said drain conduit upright segment; such that water in said track flows through said linking segment and into said upright segment and accumulates as a column within said upright segment above said check valve and then drains through said check valve when the column reaches a sufficient height and thus a sufficient weight to overcome the opposing force of outside air pressure.
