In-ground pop-up sprinkler with above ground hose connection

摘要

A pop-up sprinkler assembly for installation within the ground and for manual connection from a position above ground with an above ground hose as a source of water pressure. The pop-up sprinkler assembly includes a housing structure (12) having an annular opening and exterior (14) suitable for installation within the ground in a fixed operative position. The housing structure (12) has an inlet passageway (36) communicating with the annular opening. A hose connector (16) is in the passageway (36) for connection to an above ground hose (302). A sprinkler head (70) is mounted in the annular space that is generally at ground level when the sprinkler head is in a lower storage position. An annular seal (72) is provided between the sprinkler head and the housing structure (12) so that the communication of water pressure with the annular space results in water pressure-biased movement of the sprinkler head from the lower storage position to a raised operative position. The sprinkler has an outlet (122) for directing water under pressure outwardly thereof onto the ground in a predetermined pattern.
