  • Patent number: 7070122
    Abstract: A wobbling irrigation sprinkler head for attachment to a water conduit has a wobbling sprinkler head facing upward from the water supply conduit. The sprinkler head has a base having an attachment portion for attaching to a water source and a nozzle mounted to the base for directing water therethrough. A wobbling water deflector head is movably attached to the base and has a water deflector pad thereon having a deflector surface of predetermined shape to deflect water being emitted from the nozzle to rotate the wobbling water deflector head. A counterbalancing skirt extends from the water deflecting head around a portion of the base and spaced from the base for rotation with a wobbling water deflector head so that counterbalancing the skirt counterbalances the water deflector head to dampen vibration forces in the deflector head.

The sprinkler head has one or more arms extending from the body around a water deflecting head. The water deflecting head is movably attached to the sprinkler head body and has a water deflecting surface positioned to deflect water from the nozzle and move the water defecting head. The bottom of the water deflecting surface has a protruding member extending therefrom, for interacting with a second protruding member extending from the arms of the sprinkler head body. The protruding members can have magnets of opposing polarity mounted therein.
