Patent ID: 8136744

Claim:
An extendable sprinkler device comprising: a base cylinder comprising a first end fluidly communicable with a second end via a through passageway having a first interior diameter; a primary extension assembly slidably coupled within the through passageway of the base cylinder and positionable between a collapsed position and an extended position, the primary extension assembly comprising: a primary extension cylinder comprising a first end fluidly communicable with a second end via a through passageway having a second interior diameter and a first exterior diameter smaller than the first interior diameter, the first end having a stop coupled thereto; and an actuator cylinder coupled with and located fixed inside the through passageway of the primary extension cylinder, the actuator cylinder comprising: a first end fluidly communicable with a second end via a through passageway having a third interior diameter and a second exterior diameter smaller than the second interior diameter, wherein the second end of the actuator cylinder is coupled with the second end of the primary extension cylinder; and one or more outlet slots disposed adjacent to its second end; a secondary extension cylinder comprising a first end fluidly communicable with a second end via a through passageway having a fourth interior diameter and a third exterior diameter smaller than the third interior diameter slidably coupled within the through passageway of the actuator cylinder and positionable between a collapsed position and an extended position, wherein the one or more outlet slots are in fluid communication with the first end of the actuator cylinder when the secondary extension cylinder is in the extended position.
