## Background
This application claims the benefit of priority of U.S. provisional application Ser. No. 61/793,263, filed Mar. 15, 2013, the disclosure of which is herein incorporated by reference in its entirety.


FIELD
This disclosure relates generally to sprinklers for supplying water to lawns, flower beds, gardens and the like, and in particular to a sprinkler having a selectable spray pattern.
BACKGROUND
Sprinklers are typically used to supply water to lawns, flower beds, gardens, and other watering areas during periods of low rainfall. One common type of sprinkler is referred to as an oscillating sprinkler, which supplies water in a generally square-shaped watering pattern. Another common type of sprinkler is referred to as an impact sprinkler, which supplies water in a generally circular watering pattern or in an arc-shaped watering pattern. The oscillating sprinkler and the impact sprinkler work well to meet the needs of residents living in a rural or a suburban environment, since the size of the resultant watering pattern is typically appropriate for the size of the watering areas in these environments.
Some urban living residents also have watering needs. Urban environments are typically associated with closely spaced (or connected) homes and smaller lawns than are found in the typical suburban environment. In general, the urban environment presents more “watering obstacles” to the resident, such as cars passing on the street, pedestrians passing on the sidewalk, and the activity of the neighbors on their lawns and driveways, for example. Accordingly, urban residents desire a sprinkler that supplies water to a smaller watering area with improved accuracy over the typical oscillating sprinkler or impact sprinkler.
Therefore, it is desirable to provide a sprinkler that meets the needs of the urban resident.
SUMMARY
According to an exemplary embodiment of the disclosure, a water sprinkler includes a base configured to rest on a surface, a barrel assembly, a primary fluid inlet, and a plurality of nozzle structures. The barrel assembly is rotatably supported by the base and defines a plurality of fluid channels, each fluid channel extending from a corresponding fluid inlet of a plurality of fluid inlets to a corresponding fluid outlet of a plurality of fluid outlets. The primary fluid inlet is supported by the base and is configured to be fluidly coupled to a selected fluid inlet of the plurality of fluid inlets by rotating the barrel assembly to a position that aligns the selected fluid inlet with the primary fluid inlet. The plurality of nozzle structures is supported by the barrel assembly.

DETAILED DESCRIPTION
For the purpose of promoting an understanding of the principles of the disclosure, reference will now be made to the embodiments illustrated in the drawings and described in the following written specification. It is understood that no limitation to the scope of the disclosure is thereby intended. It is further understood that the present disclosure includes any alterations and modifications to the illustrated embodiments and includes further applications of the principles of the disclosure as would normally occur to one skilled in the art to which this disclosure pertains.
A. Water Sprinkler having a Rotatable Barrel for Selecting a Spray Pattern
As shown in FIGS. 1 and 2, a sprinkler 100 includes a water connection assembly 104, a barrel assembly 108, and a base 17 (FIG. 1) configured to rest on a surface, such as the ground or any other surface. With reference to FIG. 2, the water connection assembly 104 includes a hose washer 1, a shank 2, a coupling nut 3, and a retainer plate assembly 110. The hose washer 1 is an elastomeric washer that defines an opening 112 configured to enable water to flow therethrough. The hose washer 1 is further configured to be seated against a connection fitting of a garden hose (not shown). The term “garden hose,” as used herein, includes any type of water supply line that is suitable for connection to the sprinkler 100.
The shank 2 includes a shoulder 114 and a tube 116 and defines an opening 118 therethrough. The shoulder 114 is positioned against the hose washer 1. The tube 116 has a narrower outside diameter than an outside diameter of the shoulder 114. The shank 2 is formed from injection molded thermoplastic or any other material as desired by those of ordinary skill in the art.
The coupling nut 3 defines a threaded interior 120 and a primary fluid inlet 122 therethrough. The primary fluid inlet 122 is supported by the base 17. The threaded interior 120 is configured to connect the coupling nut 3 to the connection fitting of the garden hose. The hose washer 1 and the shoulder 114 are at least partially positioned within the coupling nut 3. The tube 116 of the shank 2 extends through the primary fluid inlet 122. An alternative embodiment of the coupling nut 4 is also shown in FIG. 2. The coupling nut 4 is a metal nut including a plastic over-mold 130.
The retainer plate assembly 110 includes a retainer plate 5 defining an inlet tube 134, a seal recess 138, and a detent recess 142. The inlet tube 134 defines an opening 146 that is in fluid communication with the opening 118 in the shank 2. The inlet tube 134 is terminated with an outlet opening 150 (FIG. 5). The tube portion 116 of the shank 2 is connected to the inlet tube 134 by a sonic weld, glue, or any other suitable connection method as desired by those of ordinary skill in the art.
The retainer plate assembly 110 further includes an o-ring 6a, a seal cup 7, and an o-ring 6b, which are at least partially positioned in the seal recess 138. The o-ring 6a, the seal cup 7, and the o-ring 6b, are configured to form a generally water tight connection between the retainer plate 110 and the barrel assembly 108 (as described in detail below).
The retainer plate assembly 110 also includes a spring 8 and a detent button 9, which are positioned in the detent recess 142. The detent button 9 is configured to be biased into contact with a selected detent seat 128 (FIG. 5) of a plurality of detent seats defined by the faceplate 124 to releasably maintain the barrel assembly 108 in a selected rotational position.
With continued reference to FIG. 2, the barrel assembly 108, includes a faceplate 124, a spray tube 10, a closure plate 15, and four patterned nozzle structures 11, 12, 13, 14, which are supported by the barrel assembly 108 and which are also referred to herein as “pattern plates.” The faceplate 124 is a generally circular plate that defines four circular fluid inlets 152 therethrough. The faceplate 124 is connected to the spray tube 10. The primary fluid input 122 is fluidly coupled to the selected fluid inlet 152 when the detent button 9 is biased into the selected detent seat 128.
The spray tube 10 includes a cylindrical portion 123, a quadrilateral portion 125, and another cylindrical portion 126. The portions 123, 125, 126 are integrally formed as a monolithic part or an assembly of any combination of the portions 123, 125, 126. The spray tube 10 is formed form injection molded thermoplastic or any other material, as desired by those of ordinary skill in the art. In another embodiment, the entire spray tube 10 is generally cylindrical.
As shown in FIG. 3, the spray tube 10 defines a plurality of fluid channels 154. The fluid channels 154 extend at least from a corresponding one of the fluid inlets 152 to a corresponding one of a plurality of fluid outlets 170. The fluid channels 154 are isolated from each other by ribs 158 positioned within the spray tube 10. Each of the fluid channels 154 is aligned with one of the fluid inlets 152 through the faceplate 124. In another embodiment, the spray tube 10 has any number of fluid channels 154 and fluid outlet 170, including multiple fluid outlets 170 associated with the same fluid channel 154. For example, the spray tube 10 has between one to ten fluid channels 154 and between one to ten associated fluid outlets 170. The primary fluid inlet 122 is configured to be fluidly coupled to a selected fluid inlet 152 by rotating the barrel assembly 108 to a position that aligns the selected fluid inlet 152 with the primary fluid inlet 122.
With reference to FIG. 4, the closure plate 15, which is also referred to herein as an end cap, is connected to the spray tube 10 with a sonic weld, glue, or any other connection as desired by those of ordinary skill in the art. The closure plate 15 is an imperforate plate that closes or caps the fluid channels 154 defined by the spray tube 10. The closure plate 15 includes an extension shaft 132 that, in some embodiments, is configured to be connected to the base 17 of the sprinkler 100. In some embodiments, the extension shaft 132 is usable as a knob to rotate the barrel assembly 108.
As shown in FIG. 2, the nozzle structures 11, 12, 13, 14 are connected to the spray tube 10 with a sonic weld, glue, or any other connection as desired by those ordinary skill in the art. Each nozzle structure 11, 12, 13, 14 covers one of the fluid outlets 170 in the spray tube 10, such that each nozzle structure is configured to sealingly engage at least one of the fluid outlet 170. Each nozzle structure 11, 12, 13, 14 defines at least one outlet opening passage 174 that is fluidly connected to one of the fluid channels 154 and that is configured to emit a fluid flow.
A body 16 of the sprinkler 100 is located near the closure plate 15 of the spray tube 10. The body 16 defines a cavity 178 in which at least a portion of the closure plate 15 is positioned. The body 16 includes a snap leg 182 that connects the body 16 and the spray tube 10 to the base 17.
With reference again to FIG. 1, the base 17 is a full base that is connected to the water connection assembly 104 and to the body 16 (not shown in FIG. 1). The base 17 is formed from injection molded thermoplastic, cast from metal, or formed from any other material as desired by those of ordinary skill in the art. The base 17 is configured to rotatably support the barrel assembly 108 in a manner that enables the spray tube 10 to be rotated relative to the base (as described below in detail) about a longitudinal axis 616 (FIG. 33). An alternative embodiment of the base, referred to as a short base 186 is also shown in FIG. 2.
As shown in FIGS. 5 and 6, in operation, the sprinkler 100 emits water from one of the nozzle structures (nozzle structure 12 as shown in FIGS. 5 and 6) to supply water to an area to be irrigated. To prepare the sprinkler 100 for irrigation, first the user selects a desired one of the nozzle structures 11, 12, 13, 14. Then the user rotates the barrel assembly 108 relative to the water connection assembly 104 and the base 17, so that the desired nozzle structure 12 is facing away from the base 17.
As the user rotates the barrel assembly 108 to select one of the nozzle structures 11, 12, 13, 14, the fluid inlets 152 are moved relative to the retainer plate 5. When one of inlets 152 is aligned with the outlet opening 150, that inlet 152 and its associated fluid channel 154 are fluidly coupled to the inlet tube 134 and are configured to receive water from the water source through the primary fluid inlet 122. In the embodiment of FIGS. 5 and 6, only one of the fluid channels 154 is configured to be coupled to the water source at a time. Accordingly, no other fluid channel 154 receives water from the water source except for the fluid channel 154 that is aligned with the outlet opening 150.
As the barrel assembly 108 is rotated, the detent button 9 periodically engages one of a plurality of detent seats 128 (FIG. 5, only one shown, see also FIG. 2 four of the detent seats 128 are shown) formed in the faceplate 124. The detent button 9 engages one of the detent seats 128 when the one of the inlets 152 is aligned with the outlet opening 150. When the detent button 9 engages one of the detent seats 128, a vibration or an audible noise is made as the detent spring 8 biases the detent button 9 against the faceplate 124. The vibration or audible noise indicates to the user that one of the nozzle structures 11, 12, 13, 14 is in a position to be supplied with water. Accordingly, the barrel assembly 108 is positively engaged in each of the four positions (in the embodiment of FIGS. 5 and 6) in which a nozzle structure 11, 12, 13, 14 is configured to be supplied with water.
The o-ring 6a, the seal cup 7, and the o-ring 6b form a water tight seal between the retainer plate 5 and the faceplate 124. The water tight seal prevents water from exiting the outlet opening 150 and leaking from between the retainer plate 5 and the faceplate 124.
Next, the user connects the coupling nut 3 to the garden hose. Thereafter, the user supplies the sprinkler 100 with water from the garden hose. As shown in FIG. 5, the water flows through shank 2 and the primary fluid inlet 122 of the coupling nut 3 and then enters the retainer plate 5 though the opening 146 in the inlet tube 134. Then, the water flows out the retainer plate 5 through the outlet opening 150 and into one of the fluid channels 154 through one of the inlet 152. The water exits the fluid channel 154 through the fluid outlet 170 and flows from the nozzle structure 12 through the passage 174.
During operation of the sprinkler 100 the barrel assembly 108 remains stationary relative to the water connection assembly 104 and the base 17. Accordingly, the barrel assembly 108 does not rotate or oscillate. This enables a user to precisely position the stream of water flowing from the sprinkler 100 onto a particular well-defined area, as is useful in an urban environment.
If the user desires to select a different spray pattern, first the water from the garden hose is stopped. Second, the user rotates the barrel assembly 108 until another one of the nozzle structures 11, 12, 13, 14 and its associated fluid channel 154 are aligned to receive water from the outlet opening 150. In this way, a desired spray pattern is easily selectable by the user.
As shown in FIGS. 7-11, the nozzle structure 11 (and various embodiments thereof) is shown mounted to the spray tube 10 (and various embodiments thereof). With reference to FIG. 7, the spray tube 10 includes a raised ridge 200 on which the nozzle structure 11 is seated. The nozzle structure 11 is configured to be sonically welded to the raised ridge 200. Alternatively, the nozzle structure 11 is glued or any other connection method is used, as desired by those of ordinary skill in the art, to connect the nozzle structure to the raised ridge 200.
As shown in FIG. 8, the spray tube 10 includes a raised structure 204 on which the nozzle structure 11 is seated. The nozzle structure 11 is configured to be sonically welded to the raised structure 204. Alternatively, the nozzle structure 11 is glued to the raised structure 204.
As shown in FIG. 9, the nozzle structure 11 and the fluid outlet 170 define a circular periphery. In this embodiment the nozzle structure 11 is structured to be spin welded to the spray tube 10. To spin weld the nozzle structure 11, the nozzle structure 11 is gripped and spun while being pushed into the fluid outlet 170. The resultant friction partially melts the nozzle structure 11 and the spray tube 10. Upon cooling the nozzle structure 11 and the spray tube 10 are welded together.
With reference to FIG. 10, the nozzle structure 11 is connected to the spray tube 10 by being inserted into the fluid channel 154 and then being pressed into the fluid outlet 170 from within the fluid channel 154 by a mandrel 208. Accordingly, the nozzle structure 11 is formed from a resilient material that is deformable to fit through the fluid outlet 170 and then returns to shape thereafter. To connect the next nozzle structure 11 the spray tube 10 is rotated to match the water passage segment and then another nozzle structure is inserted into the next fluid channel 154.
As shown in FIG. 11, the nozzle structure 11 of FIG. 10 includes a perimeter seal bead 212 that forms a water tight seal between the nozzle structure and the spray tube 10. Accordingly, no welding or glue is required to connect the nozzle structure 11 to the spray tube 10; nonetheless, welding and/or glue is usable to further seal the nozzle structure 11 and the spray tube 10.
In FIGS. 12a and 12b, a nozzle structure 214 includes four resilient latching members 218 (two of which are shown). The latching members 218 grip an interior side 220 of the spray tube 10 to connect the nozzle structure 214 to the spray tube 10. A rubber seal 222 forms a water tight seal between the nozzle structure 214 and the spray tube 10. The nozzle structure 214 is configured to compress the rubber seal 222 when the nozzle structure 214 is connected to the spray tube 10. The compression of the rubber seal 222 fills any voids between the nozzle structure 214 and the spray tube 10 so that the water tight seal is formed. In another embodiment, the nozzle structure 214 includes any number of resilient latching members 218.
Another embodiment of a sprinkler 230 is shown in FIG. 13. The sprinkler 230 includes a fluid delivery assembly including a barrel assembly 234 and a water connection assembly 238. The barrel assembly 234 includes four nozzle structures 246 (three of which are shown) and is rotatably mounted to the water connection assembly 238. The water connection assembly 238 is connected to a base 242.
The sprinkler 230 operates the same as sprinkler 100 to enable the user to rotate the barrel assembly 234 and to select a desired one of the nozzle structures 246. Water is emitted from at least one of the nozzle structures 246 during operation of the sprinkler 230.
As shown in FIG. 14A another embodiment of a sprinkler 250 includes a barrel assembly 254 that is rotatably mounted to a water connection assembly 258. The barrel assembly 254 includes four nozzle structures 262 only two of which are shown. The sprinkler 250 includes a knob 266 connected to the barrel assembly 254. The knob 266 is “grip-able” by a user to rotate the barrel assembly easily, even when the knob 266 is wet.
The sprinkler 250 operates the same as sprinkler 100 to enable the user to rotate the barrel assembly 254 and to select a desired one of the nozzle structures 262. Exemplary water patterns are shown as patterns 1-4 in FIG. 14B. Water is emitted from at least one of the selected nozzle structures 262 during operation of the sprinkler 250.
As shown in FIGS. 15A, 15B, 16, and 17, any number of sprinklers 250 are connectable to the water connection assembly 258, thereby enabling two hundred fifty six water pattern combinations to be made with the sprinkler assembly 270, shown in FIG. 17 (to arrive at two hundred fifty six water pattern combinations, water is configured to be sprayed from one nozzle structure 262 of each sprinkler 250). Exemplary water patterns are shown as patterns 1-4 in FIG. 15B.
In addition to being positionable on the ground surface, each of the above-described sprinklers 100, 230, 250, 270 is compatible with in-ground irrigation systems that are positioned at least partially below the ground surface. In the typical in-ground irrigation system, a sprinkler assembly is connected to a fluid source by a buried conduit. When not in use, the entire sprinkler assembly is located near or below the ground surface so as to be unobtrusive to activities occurring on the ground surface. When in use, however, water pressure from the fluid source causes a sprinkler head of the sprinkler assembly to automatically “pop up” above the ground surface so that water is effectively broadcast on the ground surface. Typically, the sprinkler head pops up approximately two to eight inches above the ground surface in order to enable the water emitted by the sprinkler head to flow over any vegetation planted near the sprinkler assembly. When watering is complete, a biasing member of the sprinkler assembly causes the sprinkler head to automatically return to the below ground surface position.
The sprinklers 100, 230, 250, 270 are usable with in-ground irrigation systems. For example, in one embodiment the sprinkler 100, 230, 250, 270 is included in the sprinkler head of the above-described in-ground sprinkler assembly. Accordingly, the sprinkler 100, 230, 250, 270 is configured to move relative to the ground surface between a pop-up position and a retracted position. In the pop-up position the sprinkler 100, 230, 250, 270 is positioned to deliver water to a watering area, and in the retracted position the sprinkler is positioned at or below the ground surface. In such an embodiment, the sprinkler assembly includes a spike such as the spike 658 of FIG. 2, which is configured to anchor the sprinkler assembly in the ground.
B. Collar Structure for Water Sprinkler
As shown in FIG. 18, a water sprinkler 300 includes a water connection assembly 304 and a barrel assembly 308. The barrel assembly 308 is configured for rotation relative to the water connection assembly 304. The barrel assembly 308 includes a spray tube 312 and a collar structure 316.
As shown in FIG. 19, the collar structure 316 is supported by the barrel assembly 308 and defines an axial opening 330 and a plurality of radial nozzle openings 332, 328. The barrel assembly 308 extends through the axial opening 330. The nozzle structures 324 are mounted in the nozzle openings 332, 328 and are connected to the collar structure 316 by any connection method as desired by those of ordinary skill in the art, such as sonic welding and glue.
With reference to FIG. 20, the collar structure 316 is shown fixedly connected to the spray tube 312. The collar structure 316 is connected to the spray tube 312 by any connection method as desired by those of ordinary skill in the art, such as sonic welding and glue. The collar structure 316 is connected to the spray tube 312 in a position that aligns the nozzle openings 332 and the nozzle structures 324 with the fluid outlets 336 in the spray tube 312.
The collar structure 316 simplifies assembly of the water sprinkler 300. The collar structure 316 defines a diameter 340 and the spray tube 312 includes a flange 344 that defines a diameter 348. Additionally, the water connection assembly 304 defines an inside diameter 352. Both the diameter 340 of the collar structure 316 and the diameter 348 of the flange 344 are greater than the inside diameter 352 defined by the water connection assembly 204. Accordingly, the water sprinkler 300 is assembled by inserting the spray tube 312 through the water connection structure 304 until the flange 344 is seated against the water connection assembly 304. Then collar structure 316 is slid over the end of the spray tube 312 opposite the flange 344. This design prevents the issue of having to pass the nozzle structures 324 and the ring 320 through the water connection structure 304.
In another embodiment, the barrel assembly 308 and the spray tube 312 are fixed relative to the water connection assembly 304. In this embodiment, the collar structure 316 is rotatable around the spray tube 312. Also in this embodiment, the spray tube 312 has only one water passage and does not include indexing elements.
As shown in FIG. 21, another embodiment of the barrel assembly 358 includes a spray tube 362 and a collar structure 366. The spray tube 362 is an elongated cylinder extending in a longitudinal direction 368 and is configured to define longitudinal ridges 370 that are configured to mate with longitudinal recesses 374 defined by recess structures 378 of the collar structure 366 to prevent rotation of the collar structure relative to the spray tube of the barrel assembly 358. In this embodiment, a bottom surface (not shown) of the rubber nozzle structures 382 forms a seal against the spray tube 362. Also, in at least one embodiment, the rubber nozzle structures 382 and the ring 386 of the collar structure 366 are integrally formed as a monolithic part.
With reference to FIGS. 22 and 23, another embodiment of a barrel assembly 390 is shown that includes a collar structure 394 having a ring 398 and nozzle structures 402 connected thereto. Locking of the collar structure 394 to the barrel assembly 390 is accomplished via the shape of the elements.

C. Rotatable Water Nozzle Structure
As shown in FIG. 25, a circular nozzle structure 500 includes numerous resilient latching members 504 located around a circumference of the nozzle structure 500. The latching members 504 are spaced apart from each other and include an angled surface 508 and a ledge 512. The latching members 504 are configured to secure the nozzle structure 500 to an opening in a spray tube of a sprinkler, such as the fluid outlet 170 in the spray tube 10 of the sprinkler 100 of FIG. 2.
The angled surfaces 508 cause the latching members 504 to move toward an axial center 510 of the nozzle structure 500 as the nozzle structure 500 is being inserted into one of the fluid outlets 170. Once fully inserted into the fluid outlet 170 the latching members 504 “spring” back to the position shown in FIG. 25, and the ledges 512 contact an interior side (e.g. interior side 220, FIG. 12b) of the spray tube 10 to prevent removal of the nozzle structure 500 from the fluid outlet 170.
The nozzle structure 500 is configured to be rotatably mounted on the spray tube 10 of the barrel assembly, such that the nozzle structure is rotatable relative to the spray tube 10. The rotatable nozzle structure 500 enables a user to direct the water emitted from the nozzle structure to a particular location. The nozzle structure 500 is rotatable a full 360 degrees.
As shown in FIGS. 26a and 26b, another circular nozzle structure 516 is rotatably connected to a spray tube 518 of a sprinkler. The nozzle structure 516 includes a grip surface 520 configured to simplify rotating the nozzle structure 516 even when the nozzle structure and grip surface are wet. The nozzle structure 500 and the nozzle structure 516 are rotatable about an axis 524 that is perpendicular to or skewed to an axis 528 about which the spray tube 518 is rotatable.
The nozzle structures 500, 516 are rotatable to enable the output water stream to be positioned without having to move the base of the sprinkler, as is typical with known sprinklers (an example of which is shown in FIG. 26c).
As shown in FIG. 27 another embodiment of the sprinkler 534 includes a barrel assembly 538 that is rotatably mounted to a water connection assembly 542.

In FIG. 28 the sprinkler 534 includes a flow control system 500 having adjustment knobs 554. By rotating the adjustment knobs 554 the amount of water output from the sprinkler 534 is controllable, as shown in the exemplary water patterns 558 of FIGS. 29A, 29B, 29C, and 29D, which includes pattern sizes and complex shapes.
In FIGS. 30a, 30b, 31A, 31B, and 31C other water emitting devices 562, 564, 566, 568, 570 are shown. The devices 562, 564, 568, and 570 each include a rotatable turret 574 that is used to select a water pattern structure 578.
The device 564 of FIG. 30b includes a nozzle structure 582 that is rotatable relative to the turret 574. The nozzle structure 582 eliminates the need for three separate water pattern structures 586, which each have the same shape but have a different angular position, as shown in FIG. 30a. The device 564 also includes another nozzle structure 590 that is rotatable relative to the turret 574. The device 564 offers an infinite number of pattern orientations and at the same has a smaller turret 574, which requires less material to manufacture and offers less shipping bulk. Additionally, more of the devices 564 are able to be hanged on a retail hook than the devices 562, for example.
