ABSTRACT:
FIELD OF THE INVENTION
The invention relates in general to pop-up lawn sprinkler systems and more particularly to a protector shield, for lawn sprinkler heads, which have nested inserts which may be removed to accommodate sprinkler heads of different sizes.
DESCRIPTION OF RELATED ART
Pop-up lawn sprinkler heads are attached to underground water lines, and are normally located below ground level. When the water is turned on, the head pops-up out of the ground, so that water can be sprayed onto the lawn.
If the sprinkler heads are not protected, they may be damaged or broken by being run over by lawn mowers or automobiles. Damaged and broken sprinkler heads can be expensive to repair, and water may be leaked until the head is fixed.
Many prior art sprinkler head protector shields have been difficult to install or inadequate to protect the heads or inhibit grass growth. The complexity of other protectors makes it impractical for the average homeowners to buy and install the devices by themselves.
Also, most prior art sprinkler head protector do not blend into the lawn. Most are metallic and are brightly colored, so they detract from the appearance of the lawn.
Prior art sprinkler head protectors are usually quite slick, especially when wet, as they often are. If a person steps on a protector shield, the person would likely slip and fall down.
SUMMARY OF THE INVENTION
The invention is a lawn sprinkler head protector that is placed around the sprinkler head and pressed into the grass and/or soil in which the sprinkler head is located, and also inhibits the growth of grass adjacent to the sprinkler head. The protector has nested center inserts that may be used in combination or some removed depending upon the size of the sprinkler head.
The top surface of the protector has patterned indentations which resemble grass leaves. The top surface is also textured to provide a non-slip surface.
A plurality of openings extend around the surface to provide opening through grass can grow to completely hide the protector. The lower edges as well as the plurality of openings have a taper edge which provides a cutting edge which helps the protector to cut through grass and soil as it is pressed into the ground around a sprinkler head, and no digging is required.
