Patent ID: 7416361

Claim:
An extendable pole for window washing comprising: a plurality of substantially hollow elongated rigid tubular sections, each of said tubular sections having a lower end and an upper end and a substantially cylindrical outer side wall extending between said lower and upper ends; a first mechanical connector connected to the lower end of each of said tubular sections and a second mechanical connector connected to the upper end of each of said tubular sections, the first mechanical connector of one of said tubular members being adapted to mechanically connect to the second mechanical connector of another tubular section so as to form a pole having a length equal to the combined length of said tubular sections being connected; a lower aperture in the side wall of each of said tubular sections adjacent the lower end thereof and an upper aperture in the side wall of each of said tubular sections adjacent the upper end thereof; an elongated tube associated with each of said tubular sections, each tube being slightly longer than its associated tubular section and having a lower end and an upper end, a substantial portion of the length of each tube lying within the interior of its associated tubular section, the lower end of each tube passing through the lower aperture of its associated tubular section to the exterior thereof and the upper end of each tube passing through the upper aperture of its associated tubular section to the exterior thereof, and fluid connectors at the ends of each of said tubes whereby the lower end of one tube can be connected to the upper end of a different tube so that the tubes are in fluid communications with each other.
