  • Patent number: 5687909
    Abstract: The present invention is a lawn sprinkler securing apparatus comprising a spike with an extension attached substantially perpendicularly to the side of the spike. A coupling is attached to the end of the offset which is opposite the end attached to the spike. The coupling has an opening which is designed to receive and hold upright a commercially available sprinkler head. The coupling also has a hose attachment for receiving a standard garden hose for conducting fluid from a hose attached to the hose attachment through a passage in the coupling to the sprinkler head. The offset configuration of the present invention allows a user to impart substantial force in driving the spike into the ground, either by hand, by foot, or with a tool such as a hammer, virtually without the possibility of damaging the sprinkler head.
