ABSTRACT:
A new and improved lawn sprinkler apparatus includes a portable, nonrotating body assembly which includes an adaptor assembly for connecting to a water source. The body assembly includes an internal water flow path. A rotatable sprinkler head assembly receives water from the water flow path and dispenses water through a plurality of water nozzles supported by the rotatable sprinkler head assembly. A rotatable, water-tight connection assembly connects the rotatable sprinkler head assembly to the water flow path of the body assembly. A rotatable decorative assembly is connected to the body assembly. The decorative assembly includes a paddle wheel which is driven by water flowing in the water flow path. The body assembly simulates a helicopter body; the rotatable sprinkler head assembly simulates a main helicopter rotor; and the decorative assembly simulates a helicopter tail rotor. A fertilizer containment chamber assembly is supported by and is contained within the body assembly and is placed in-line with the water flow path. The rotatable, water-tight connection assembly includes a stationary sealing surface connected to the body assembly and includes a rotatable sealing surface connected to the rotatable sprinkler head assembly. A simulated helicopter ground-contacting assembly is connected to a bottom side of the body assembly for supporting the body assembly on a ground. A ground-penetrating spike is connected to the body assembly for penetrating into a portion of ground for preventing the body assembly from moving along the ground.
