Definitions

  • the present invention relates to a lawn sprinkler, and more particularly to an adjustable lawn sprinkler that can conveniently adjust the pattern and speed of water sprayed from the sprinkler.
  • one type of conventional sprinkler comprises a base (60) and a rotatable disk (70).
  • the base (60) is placed on the ground and has a top (not numbered), a side inlet (not numbered) and an outlet (not shown).
  • a hose (62) connected to an external water source is connected to the side inlet and supplies water to the base (60).
  • the outlet is defined in the top of the base (60) and communicates with the side inlet.
  • the rotatable disk (70) is rotatably mounted on the base (60) and has atop and multiple nozzles (72) defined on the top. Each nozzle (72) sprays a different pattern and can be aligned selectively with the outlet on the base (60) so water sprays out through the selected nozzle (72).
  • this type of conventional lawn sprinkler cannot rotate to spray water over a large area.
  • a second type of conventional lawn sprinkler comprises a base (80) and multiple nozzles (90).
  • the base (80) is a short cylinder, is attached rotatably to a hose and has a side surface and three water outlets (not shown) defined in the side surface.
  • the nozzles (90) are rotatably mounted respectively on the water outlets.
  • Each nozzle (90) has an inclined distal face (not numbered) and multiple holes (not numbered) so water sprays from the sprinkler through the holes and rotates the lawn sprinkler. Rotating the nozzle heads (90) on the side surface changes the direction water sprays from the lawn sprinkler.
  • the main objective of the present invention is to provide an adjustable lawn sprinkler that has multiple patterns and rotating speeds.
  • the adjustable lawn sprinkler in accordance with the present invention comprises a rotating base and a rotatable disk.
  • the rotating base has an outlet.
  • the rotatable disk is mounted rotatably on the rotating base and has multiple nozzle recesses and multiple nozzles.
  • the nozzles have different patterns and are rotatably mounted respectively in the nozzle recesses.
  • a specific sprinkling pattern is selected, Moreover, turning the nozzle in its nozzle recess changes the direction water is sprayed from the rotatable disk. This changes the tangential component of force applied to the rotating base and the speed of the adjustable lawn sprinkler.
  • the adjustable lawn sprinkler in accordance with the present invention comprises a base (10), a rotatable disk (20) and one or more optional radial nozzles (30).
  • the base (10) is attached rotatably to a hose (not shown) and has a body, a lower rotary connector, a upper rotary connector, a main outlet (14), a channel, an optional lighting device (17), an optional positioning device and multiple optional auxiliary outlets (16).
  • the body is circular and has a center, an outer edge, a top face, a bottom face and a skirt.
  • the bottom face has a center.
  • the skirt is formed on and extends down from the outer edge.
  • the lower rotary connector may be implemented with a hollow shaft (12) attached to the center of the bottom face of the base (10) and attached rotatably to a hose.
  • the upper rotary connector may be implemented with an annular groove (102) and multiple bosses (104).
  • the annular groove (102) is formed around the top face of the base (10) near the outer edge and has an inner face.
  • the multiple bosses (104) are formed on the inner face of the annular groove (102).
  • the main outlet (14) is defined through the top face of the base (10).
  • the channel is formed on the bottom face of the base (10) between the hollow shaft (12) and the main outlet (14) to allow water to flow to the main outlet (14) from the hollow shaft (12).
  • the lighting device (17) is mounted under the base (10), is aligned with the main outlet (14) to light water sprayed from the adjustable lawn sprinkler and has a sensor.
  • the sensor detects water flowing through the adjustable lawn sprinkler and turns on the lighting device (17).
  • the positioning device selectively keeps the base (10) from rotating and comprises a sleeve (15) and a clasp (152).
  • the sleeve (15) is mounted securely in the hose and rotatably around the hollow shaft (12) and has a top, an outer surface, a notch (151) and an exterior thread.
  • the notch (151) is defined in the top of the sleeve (15).
  • the exterior thread is defined around the outer surface to attach the positioning device conveniently to a hose.
  • the clasp (152) is attached pivotally to the hollow shaft (12), is rectangular, is bent to a V-shape and has two points and two mounting pins. The pins extend inward toward each other from the points of the clasp (152) and are attached pivotally to the hollow shaft (12) near the bottom face of the base (10). Thereby, the clasp (152) can be pivoted to engage the notch (151) in the sleeve (15) and keep the base (10) from rotating or pivoted against the bottom face to allow the base (10) to rotate.
  • the auxiliary outlets (16) are formed in the skirt of the base (10) and communicate with the main outlet (14).
  • the rotatable disk (20) may be a round cover, is rotatably mounted on the base (10) and has a top face, a bottom face, a skirt, a rotary connector, multiple optional nozzle recesses (22), an optional central spray hole (23), multiple optional outlet holes (25), an optional annular dividing wall (29) and multiple nozzles (24).
  • the rotary connector connects rotatably to the upper rotary connector on the base (10) and may be implemented with an annular flange (202) and multiple detents (204).
  • the annular flange (202) is formed around the bottom face of the rotatable disk (20), is mounted rotatably in the annular groove (102) in the base (10) and has an outer edge.
  • the multiple detents (204) are defined in the outer edge of the annular flange (202), correspond to the bosses (104) and engage the bosses (104) on the base (10) so that the rotatable disk (20) can be held in a desired position relative to the base (10).
  • the nozzle recesses (22) are defined in the top face of the rotatable disk (20) in a circular arrangement, correspond to the detents (204) and bosses (104), selectively align with the main outlet (14) in the base (10) when the detents (204) engage the bosses (104) and may be tubular posts attached to the bottom face of the rotatable disk (20).
  • the central spray hole (23) is formed through the rotatably disk (20) to spray water up from the adjustable lawn sprinkler.
  • the outlet holes (25) are formed through the rotatable disk (20) between the nozzle recesses (22) and the skirt to provide a fine upward spray or mist and are evenly distributed around the rotatable disk (20).
  • the annular dividing wall (29) is formed on and extends down from the bottom face of the rotatable disk (20) in conjunction with the nozzle recesses (22) to form an inner area and an outer area and may have an outer semicylindrical partition (292) and an inner semicylindrical partition (294).
  • the inner area communicates with the central spray hole (23).
  • the outer area communicates with the outlet holes (25).
  • the outer semicylindrical partition (292) is an outward curve in the annular dividing wall (29) that selectively corresponds to the main outlet (14) in the base (10) to direct water to the inner area to be sprayed from the central spray hole (23).
  • the inner semicylindrical partition (294) is an inward curve in the annular dividing wall (29) that selectively corresponds to the main outlet (14) in the base (10) to direct water to the outer area to be sprayed from the small outlet holes (25).
  • the nozzles (24) are mounted respectively in the nozzle recesses (22) and may be mounted securely or rotatably in the nozzle recesses (22).
  • Each nozzle (24) has a top, at least one optional rib (242) and an outlet.
  • the at least one rib (242) is formed on and protrudes up from the top of the nozzle (24) to rotate the nozzle (24) easily and change the direction in which water is sprayed from the nozzle (24)
  • the outlets are formed in the tops respectively of the nozzles (24) and are different shapes to provide different spray patterns.
  • spot watering is accomplished by orienting the outlet of the nozzle (24) in a radial direction relative to the adjustable lawn sprinkler.
  • the radial nozzles (30) are rotatably mounted respectively in the auxiliary outlets (16).
  • Each radial nozzle (30) has a distal end, an inclined face (32) and multiple holes.
  • the inclined face (32) is defined at the distal end.
  • the holes are defined on the inclined face (32).
