PRIORITY DOCUMENTS

[0001] The present application claims priority from Australian Provisional Patent Application No.

2019903722 titled “SPRINKLER ASSEMBLY IMPROVEMENTS” and filed on 3 October 2019, the content of which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

[0002] The present disclosure relates to a sprinkler assembly. In a particular form the present disclosure relates to a sprinkler assembly capable of directing a stream of water in a rectilinear pattern around the sprinkler assembly.

BACKGROUND

[0003] Sprinklers are well known for their use in irrigation. Presently available sprinklers are generally designed to manipulate a stream of water to irrigate an area around the sprinkler. Various means are utilised to manipulate, direct and distribute water around the sprinkler, so as to provide the designed irrigation coverage. The presently available sprinklers generally comprise one or more elements that either rotate or are manipulated to deflect the stream of water to achieve the desired irrigation coverage. These one or more elements often wear with use, or are easily damaged resulting in a reduced lifespan for the sprinkler.

[0004] The most commonly available means for manipulating, directing and distributing water around the sprinkler result in a circular pattern around the sprinkler. However, not all areas requiring irrigation are circular, and are often square in shape (such as domestic lawns, sand tennis courts and the like). Thus, multiple sprinkler systems are often utilised to provide sufficient irrigation coverage for square or straight-edged areas, often resulting in added cost of additional sprinklers, sections of overlapping streams and increased cost of water usage.

[0005] There is thus a need to provide a simple sprinkler design, with no elements that rotate or are manipulated to deflect a stream of water, such that the sprinkler is able to direct a stream of water in a non-circular pattern (such as a square pattern) around the sprinkler.

[0006] It is against this background and the problems and difficulties associated therewith, that the present invention has been developed. SUMMARY

[0078] Referring now to any one of Figures 1 to 4 and 7 to 10, in one embodiment, the inlet (80) of the housing (50) may be configured to direct a pressurised stream of water into the cavity (71) of the housing (50). In this way, in use, the stream of water may be deflected by the deflector (30) and the pyramid like structure (31) of the base (10), thereby directing the stream of water out of the cavity (71) of the housing (50) through the outlet (90).

[0079] In one embodiment, the inlet (80) may comprise a connection fitting (not shown). The connection fitting may be configured to connect a hose (not shown) to the sprinkler assembly (100), and in use, feed water from a source (such as a tap) to the sprinkler assembly (100).

[0080] In an alternative embodiment, the inlet (80) may be configured to receive the hose fitting.

[0081] In either of the two above embodiments, the connection fitting or the hose fitting may be one which provides for quick connection and disconnection of a feed line (such as the hose). In this way, advantageously, a user may quickly connect and disconnect the feed line (such as the hose) to the sprinkler assembly (100).

[0082] Referring to any one of the Figures, in one embodiment, both the base (10) and the housing (50) may be manufactured of a metal or a metal alloy. In this way, it will be appreciated that, advantageously, the sprinkler assembly (100) of any one of the Figures may be simple in design and manufacture, and provides a rigid sprinkler assembly (100) able to withstand rough use, wear and tear.

[0083] In alternative embodiments, both the base (10) and the housing (50) may be manufactured of a suitable plastic material, such as injection moulded plastic (for low cost of manufacture). The plastic material may be selected for its suitability in outdoor applications, such as having suitable UV rating and being rigid so as to be able to withstand rough use, wear and tear.

[0084] An exemplary method of use of the sprinkler assembly (100) of any one of the embodiments, may comprise the steps of: a. Nesting the portion of the base (10) extending between the base (10) and the deflector (30) within the cavity (71) of the housing (50); b. Ensuring the locating tab (11) of the base (10) cooperates with the receiving portion (51) of the housing (50), ensuring alignment of the one or more notches (92) to the edges (32) of the pyramid like structure (31) of the deflector (30); c. The internal profile (72) of the cavity (71 ) of the housing (50) cooperates with the peripherally circumferential lip (22) of the plate (20) of the base (10), to fonn the securement mechanism to reliably secure the base (10) to the housing (50); d. Connecting the hose (or the feedline) to the sprinkler assembly (100) via the connection fitting at the inlet (80); e. Tire pressurised stream of water enters the sprinkler assembly (100) via the hose connected at the inlet (80), travels through the fluid passage way extending through the cavity (71) toward the outlet (90), and the stream of water is directed by the cooperation of the pyramid like structure (31) of the deflector (30) and the one or more notches (92) of the outlet resulting in the rectilinear water pattern around the sprinkler assembly ( 100).

[0085] It will be apparent to those skilled in the art that the sprinkler assembly (100) disclosed in any one of the above embodiments, and the exemplary method of use above, advantageously provides the geometrically rectilinear water spray pattern around the sprinkler assembly (100). In this way, the sprinkler assembly ( 100) is advantageously more economical with water usage, and the number of sprinklers required for coverage, when used for irrigation of areas that are not circular in shape (such as domestic lawns, sand tennis courts and the like). A further advantage of the sprinkler assembly (100) is in its simple construction and design, in that it is designed with no elements that rotate or are manipulated to deflect the stream of water. In this way, the sprinkler assembly ( 100) provides for a long life sprinkler assembly that is less likely to wear with use, or be easily damaged by wear and tear.

[0086] It will further be apparent to those skilled in the art that the geometrically rectilinear water spray pattern of the sprinkler assembly ( 100) disclosed in any one of the above embodiments is resultant of the cooperation between the one or more notches (92) disposed on the rim (91) of the outlet (90), and the pyramid like structure (31) of the deflector (30) being proximal thereto. Although not illustrated in the Figures, in alternative embodiments, the tip of the deflector (30) may be an alternative shape to the pyramid like structure (31 ), wherein in use it is envisaged that the alternative shape will cooperate with alternative composition of the rim (91 ), similar to the function of the one or more notches (92), to direct the stream of water in the rectilinear pattern around the sprinkler assembly (100). In such alternative embodiments, any alternative shape of the top of the deflector (30) may comprise, in cross-section, a square surface positioned proximal to the composition of the rim (91) to cooperate therewith. [0087] Throughout the specification and the claims that follow, unless the context requires otherwise, the words “comprise” and “include” and variations such as “comprising” and “including” will be understood to imply the inclusion of a stated integer or group of integers, but not the exclusion of any other integer or group of integers.

[0088] The reference to any prior art in this specification is not, and should not be taken as, an acknowledgement of any form of suggestion that such prior art fonns part of the common general knowledge.

[0089] It will be appreciated by those skilled in the art that the disclosure is not restricted in its use to the particular application described. Neither is the present disclosure restricted in its preferred embodiment with regard to the particular elements and/or features described or depicted herein. It will be appreciated that the disclosure is not limited to the embodiment or embodiments disclosed, but is capable of numerous rearrangements, modifications and substitutions without departing from the scope of the disclosure as set forth and defined by the following claims.
