摘要：A lawn sprinkler has a sprinkler head secured to the upper end of a water-supply pipe which is disposed in the ground. The upper side of the sprinkler head issubstantially flush with the upper surface of the ground, and a grass guard is disposedunder the sprinkler head with the water supply pipe extending through an aperture inthe grass guard. The grass guard comprises a plate-like member which includes two ormore complementary sections, the complementary sections being engaged togetherunder the sprinkler head by tongue and groove joints at their edges to form the guardplate-like member having the aperture therethrough, with the water supply pipeextending through the aperture. Disengagement and removal of a complementarysection from the other section results in a passageway or clearance channel of width atleast slightly larger than the outer diameter of the water supply pipe. Consequently thegrass guard can be relatively easily and quickly removed, when broken, and replacedwithout requiring the prior removal and subsequent reinstallation of the sprinkler head.
