Abstract
A pop-up sprinkler assembly includes a housing cover which is readily, vertically adjustable relative to a main housing within which extends a sprinkler head unit arranged in an adapter sleeve that is interengaged with the main housing to establish a blow-out feature. A readily accessible, preferably threadably mounted solenoid is used to control a main water flow valve positioned below an associated frost line. A dirt shield protects the solenoid, as well as a releasable connection between the main housing and the housing cover, from contamination. A hose adapting element is provided to be selectively secured about the sprinkler head unit atop the housing cover.
Claims27
A sprinkler assembly comprising:
- a main housing having first and second open ends and an interior chamber, said first end being adapted to receive a flow of water;
- an adapter sleeve having a first end portion extending through the second end of the main housing and into the interior chamber, and a second end portion projecting from the main housing;
- a sprinkler head unit positioned within the adapter sleeve and shiftably mounted relative to the main housing;
- a main valve adapted to direct the flow of water into the main housing and through the sprinkler head unit;
- a housing cover including a top cover portion extending across the main housing and a body portion which extends concentrically about the second end of the main housing, said housing cover being selectively shiftable, substantially vertically relative to the second end of the main housing;
- means for releasably securing the housing cover relative to the main housing;
- an opening formed in the top cover portion of the housing cover, said opening leading to a zone radially outwardly of the main housing;
- a switch housing, electrically linked to the main valve, located in the zone;
- and
- a solenoid valve assembly for opening and closing the main valve, said solenoid valve assembly being positioned in said zone, readily removably attached to the switch housing, and accessible through said opening;
- and
- a hose connection element sealably mounted to the housing cover about the sprinkler head unit.
A sprinkler assembly comprising:
- a main housing having first and second open ends and an interior chamber, said first end being adapted to receive a flow of water;
- an adapter sleeve having a first end portion extending through the second end of the main housing and into the interior chamber, and a second end portion projecting from the main housing;
- a sprinkler head unit mounted within the adapter sleeve;
- and
- a main valve adapted to direct the flow of water into the main housing and through the sprinkler head unit.
A sprinkler assembly comprising:
- a main housing having first and second open ends and an interior chamber, said first end being adapted to receive a flow of water;
- a sprinkler head unit mounted within the main housing;
- a main valve adapted to direct the flow of water into the main housing and through the sprinkler head unit;
- a housing cover including a top cover portion extending across the main housing and a body portion which extends concentrically about the second end of the main housing, said housing cover being selectively shiftable, substantially vertically relative to the second end of the main housing;
- and
- means for releaseably securing the housing cover relative to the main housing.
The sprinkler assembly comprising:
- a main housing having first and second open ends and an interior chamber, said first end being adapted to receive a flow of water;
- a sprinkler head unit shiftably mounted relative to the main housing;
- a housing cover including a top cover portion extending across and being connected to the main housing;
- and
- a hose connection element sealably mounted to the housing cover about the sprinkler head unit.
A sprinkler assembly comprising:
- a main housing having first and second open ends and an interior chamber, said first end being adapted to receive a flow of water;
- a sprinkler head unit shiftably mounted relative to the main housing;
- a main valve adapted to direct the flow of water into the main housing and through the sprinkler head unit;
- a housing cover including a top cover portion extending across and being connected to the main housing;
- an opening formed in the top cover portion of the housing cover, said opening leading to a zone radially outwardly of the main housing;
- a switch housing, electrically linked to the main valve, located in the zone;
- and
- a solenoid valve assembly for opening and closing the main valve, said solenoid valve assembly being positioned in said zone, readily removably attached to the switch housing, and accessible through said opening.
In a sprinkler assembly including a main housing, a housing cover and sprinkler head unit, a method of vertically adjusting the housing cover relative to the main housing comprising:
- releasing a connection between the housing cover and the main housing;
- sliding the housing cover substantially vertically relative to the main housing while maintaining a concentric relationship between the main housing and the housing cover;
- and
- re-establishing a connection between the housing cover and the main housing.
