Abstract

An irrigation device includes a body defining a fluid passage; a slider movably coupled to the body, wherein the slider includes a body defining a plurality of apertures and a plurality of projections extending away from the body; a plurality of flexible jets coupled longitudinally to the body, wherein the plurality of flexible jets receive fluid from the fluid passage, and wherein each jet is received by an aperture in the plurality of apertures of the slider; and a toggle rotatably coupled to the body and to the slider, wherein the toggle is rotatably coupled to the body in substantial alignment with the plurality of jets, and wherein rotation of the toggle in a first direction moves the slider to cause at least one projection of the slider to engage with at least one jet to adjust a position of the at least one jet.

First claim

What is claimed is:

1. An irrigation device, comprising:
a body defining a fluid passage;
a slider movably coupled to the body of the irrigation device, wherein the slider includes a body defining a plurality of apertures and a plurality of projections extending away from the body;
a plurality of flexible jets coupled longitudinally to the body of the irrigation device, wherein the plurality of flexible jets receive fluid from the fluid passage, and wherein each jet of the plurality of flexible jets is received by an aperture in the plurality of apertures of the slider; and
a toggle rotatably coupled to the body of the irrigation device and to the slider, wherein the toggle is rotatably coupled to the body in substantial alignment with the plurality of flexible jets, and wherein rotation of the toggle in a first direction moves the slider to cause at least one projection of the slider to engage with at least one jet of the plurality of flexible jets to adjust a position of the at least one jet of the plurality of the flexible jets, wherein each projection of the plurality of projections includes an engagement surface configured to engage with a jet of the plurality of flexible jets received in an aperture when the toggle is rotated in the first direction, wherein the engagement surface has a first curved shape forcing the corresponding flexible jet into a second curved shape as the first curved shape of the corresponding engagement surface, and wherein an angle of curvature of the non-planar shaped engagement surface is different for at least two projections in the plurality of projections in such way that a projection of the plurality of projections with an engagement surface having a largest angle of curvature is disposed closest to the toggle while a projection of the plurality of projections with an engagement surface having a smallest angle of curvature is disposed further from the toggle.

2. The irrigation device of claim 1 , wherein the plurality of flexible jets are constructed from a resilient material such that the at least one jet of the plurality of flexible jets is bent into the position.

3. The irrigation device of claim 1 , wherein a constant decrease is provided with each angle of curvature for each engagement surface of each projection of the plurality projections between the projection of the plurality of projections with the engagement surface having the largest angle of curvature and the each projection between the plurality of projections with the engagement surface having the smallest angle of curvature.

4. The irrigation device of claim 1 , wherein as the toggle is rotated in the first direction, an angle of a tab of the toggle substantially matches an angle of a jet of the plurality of flexible jets disposed closest to the toggle.

5. The irrigation device of claim 1 , wherein the irrigation device is an oscillating sprinkler such that at least a portion of the body rotates about an axis that is substantially aligned with a longitudinal axis of the fluid passage.

6. The irrigation device of claim 5 , wherein rotation of the toggle is about an axis that is perpendicular or substantially perpendicular to the axis of rotation for at least the portion of the body.

7. A sprinkler, comprising:
a body defining a fluid passage;
a frame coupled to the body, the frame disposed in an internal volume of the body proximate the fluid passage, wherein the frame defines a plurality of apertures;
a first toggle movably coupled to the body;
a first slider disposed within the internal volume of the body and coupled to the first toggle, the first slider defining a plurality of apertures and a plurality of projections extending away from the body; and
a first plurality of jets coupled to the frame, wherein each jet in the first plurality of jets is received by an aperture of each of the first slider and the frame, and wherein fluid from the fluid passage is selectively provided to the first plurality of jets;
wherein the first toggle is movable between a first position and a second position, wherein movement of the first toggle to the second position moves the first slider in a same direction as the first toggle, wherein the movement of the first slider in the same direction causes the first slider to move at least one jet in the first plurality of jets in the same direction such that the at least one jet in the first plurality of jets moves in the same direction as the first toggle, wherein each projection of the plurality of projections includes an engagement surface configured to engage with a jet of the first plurality of jets received in an aperture when the toggle is rotated in the first direction, wherein the engagement surface has a first curved shape forcing the corresponding jet of the first plurality of jets into a second curved shape as the first curved shape of the corresponding engagement surface, and wherein an angle of curvature of the non-planar shaped engagement surface is different for at least two projections in the plurality of projections in such way that a projection of the plurality of projections with an engagement surface having a largest angle of curvature is disposed closest to the first toggle while a projection of the plurality of projections with an engagement surface having a smallest angle of curvature is disposed further from the first toggle.

8. The sprinkler of claim 7 , wherein as the first toggle is moved to the second position, an angle of a tab of the first toggle substantially matches an angle of a jet in the first plurality of jets disposed closest to the first toggle.

9. The sprinkler of claim 7 , wherein the first toggle is aligned or substantially aligned with an alignment axis of the first plurality of jets.

10. The sprinkler of claim 7 , wherein the first plurality of jets are constructed from a resilient material such that the at least one jet is bent in the same direction when the first slider is moved in the same direction.

11. The sprinkler of claim 7 , wherein the first slider includes a body and a plurality of projections, wherein the body defines the plurality of apertures, and wherein the plurality of projections extend from the body of the first slider toward the fluid passage.

12. The sprinkler of claim 7 , further comprising a first jet bend controller coupled to the frame, wherein the first jet bend controller defines a plurality of apertures, wherein each jet in the first plurality of jets is received by an aperture in the plurality of apertures of the first jet bend controller.

13. The sprinkler of claim 7 , wherein the at least one jet contacts the first jet bend controller to aid movement of the at least one jet of the first plurality of jets in the same direction as the first toggle is moved from the first position to the second position.

14. The sprinkler of claim 7 , further comprising:
a second toggle movably coupled to the body; and
a second slider disposed within the internal volume of the body and coupled to the second toggle, the second slider defining a plurality of apertures;
a second plurality of jets coupled to the frame, wherein each jet in the second plurality of jets is received by an aperture of each of the second slider and the frame, and wherein fluid from the fluid passage is selectively provided to the second plurality of jets;
wherein the second toggle is movable between a first position and a second position, wherein movement of the second toggle to the second position moves the second slider in a same direction as the second toggle, wherein the movement of the second slider in the same direction causes the second slider to move at least one jet in the s
