Abstract
An adjustable riser connectable to a sprinkler includes a stationary channel and a hollow sleeve movable over the stationary channel. The hollow sleeve partially encloses the stationary channel to define an internal volume. Recessed columns each having a vertical slot connected to a plurality of notches are defined in the outer surface of the stationary channel. A collar engages the lower end of the hollow sleeve. One or more pins extend through the collar and hollow sleeve to contact the stationary channel to allow the sleeve to be moved vertically over the stationary channel and rotated into one of the notches to lock the sleeve into a set vertical position.
Claims19
An adjustable riser for an irrigation system, comprising:
- a stationary channel having an open upper end, a lower end, and a body extending between the open upper end and the lower end, an internal flow channel defined through the body, and a plurality of notches defined along a longitudinal length of the body;
- a hollow sleeve configured to at least partially enclose the stationary channel, the hollow sleeve having a closed upper end, an open lower end, and an upper stem configured to engage a sprinkler extending from the closed upper end, and at least two holes defined through the hollow sleeve, wherein the open lower end is configured to slidably engage the stationary channel;
- a collar engaged to the open lower end of the hollow sleeve, the collar having at least two apertures defined therethrough, wherein the hollow sleeve comprises at least two holes substantially concentrically aligned with the at least two apertures;
- and
- a means for removably locking the hollow sleeve at a set vertical position on the stationary channel.
An adjustable riser for an irrigation system, comprising:
- a static channel having a cylindrical body extending between an open upper end and a closed lower end having a threaded stem configured to engage a water source, two or more recessed columns defined in an outer surface of the body, wherein each recessed column has a plurality of stacked notches connected to a vertical slot;
- a gripping sleeve movable over the static channel, the gripping sleeve having an open lower end engaged over the open upper end of the static channel to define an internal volume, a closed upper end, a threaded stem extending from the closed upper end and configured to engage a sprinkler, and a plurality of detents formed around an outer perimeter of the open lower end;
- a gripping collar having a plurality of teeth configured to engage the plurality of detents and lock the gripping collar to the gripping sleeve over the static channel;
- and
- a means for removably locking the gripping sleeve at a set vertical position on the static channel.
An adjustable riser for an irrigation system, comprising:
- a stationary channel having an open upper end, a lower end, and a body extending between the open upper end and the lower end, an internal flow channel defined through the body, and a plurality of notches defined along a longitudinal length of the body;
- at least one vertically recessed slot defined in an outer surface of the body, wherein each notch is linked to the vertically recessed slot to define at least one recessed column such that each notch defines one set vertical position on the stationary channel;
- a hollow sleeve configured to at least partially enclose the stationary channel, the hollow sleeve having a closed upper end, an open lower end, and an upper stem configured to engage a sprinkler extending from the closed upper end and wherein the open lower end is configured to slidably engage the stationary channel;
- a collar engaged to the open lower end of the hollow sleeve;
- and
- at least one pin extending through the collar and the hollow sleeve to contact the body of the stationary channel and removably lock the hollow sleeve at the set vertical position of one of the notches.
