ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to lawn sprinklers and, more particularly, to an improved structure of swivel lawn sprinkler, which oscillates the wings of two figured ornaments when the spray tube is rotated to sprinkle water on the lawn.
In parks, gardens, square plazas, or the like, lawn sprinklers may be provided to sprinkle water on flowers, lawns, trees, and etc. Regular lawn sprinklers are commonly comprised of a fixed spray tube having a plurality of jet nozzles for output of water. These conventional lawn sprinklers do not attract people's attention when sprinkling water on plants because they are immovable.
SUMMARY OF THE INVENTION
It is one object of the present invention to provide a lawn sprinkler, which has a figured swivel sprinkler head that attracts people's attention when sprinkling water on the lawn. It is another object of the present invention to provide a lawn sprinkler, which is forced to rotate the sprinkler head thereof when sprinkling water on the lawns. It is still another object of the present invention to provide a swivel lawn sprinkler, which moves two ornaments alternatively vertically up and down and oscillates symmetrical pairs of wings alternatively up and down upon rotary motion of the spray tube of the swivel sprinkler head during sprinkling.
