An irrigation sprinkler is described. The irrigation sprinkler includes a first ring including a first edge defining a first plurality of semicircular recesses and a second ring including a second edge defining a second plurality of semicircular recesses. The first ring and the second ring are secured together to define a plurality of circular recesses. The first ring includes a fin proximate each circular recess. The irrigation sprinkler also includes an adjustment mechanism disposed within each of the circular recesses. Each adjustment mechanism includes an outer rotating member including an annular structure comprising at least one of an annular recess and an annular protrusion, and an internal chamber including inwardly disposed threads. Each adjustment mechanism also includes an inner cylindrical member including an outer surface. The outer surface defines outwardly disposed threads and a channel. The channel extends radially along only a portion of the inner cylindrical member.

A sprinkler sleeve attachment for easily installing or replacing an in-ground sprinkler head when needed. The sprinkler sleeve attachment includes a tubular, rigid body having an open upper end and an open, tapered lower end. The sprinkler sleeve attachment further includes an internal connection member and an external connection member wherein the internal connection member is a threaded male adaption for receiving a sprinkler head thereon in liquid communication and the external connection member is a threaded female adaption disposed on the open lower end configured to receive an end of a water connection hose therein. A plurality of stabilizing fins extends orthogonally outward from an exterior surface of the tubular body wherein the stabilizing fins are oriented along a longitudinal axis thereof.

An irrigation sprinkler can include an outer case having an inlet end and an outlet end. The sprinkler can include a riser positioned at least partially within the outer case and having an upstream end and a downstream end. The riser can be configured to transition between a retracted position and an extended position wherein the downstream end is positioned on a side of the outlet end of the outer case opposite the inlet end of the outer case when the riser is in the extended position. The sprinkler can include a cup assembly connected to the downstream end of the riser, the cup assembly including organic or artificial turf therein, wherein the cup assembly is configured to be removed from the riser without emptying the turf therefrom.

In an installed sprinkler system, a sprinkler system attachment serves to absorb vertical and lateral forces that a sprinkler assembly or a protruding extension pipe may be exposed to, by providing a flexible body with one or more collapsible zones, having threaded ends or smooth, sliding-fit ends for connecting the sprinkler system attachment between two sections of the sprinkler system.

An adjustable height connection for water irrigation with a base structure, a first pipe, a second pipe and a hose attachment pipe. The first pipe telescopes into the second pipe. The second pipe is attached via a hinge member to the base structure so that it can be folded for compact storage or transport. The hose attachment pipe has a threaded inlet and outlet and is attached perpendicularly to the top of the first pipe. The first pipe includes indentations to allow a treaded locking screw to penetrate the side wall of the second pipe and engage one of the indentations of the first pipe thereby holding it in place. The base structure includes downward facing arrow shaped legs to help secure it to dirt-like ground surface.

A garden sprinkler securing structure has two base members, and one of the base members has an input opening and an output opening. The input opening is configured to connect to a water source, and the output opening is provided with a sprinkler pivoted between the two base members. When water from the water source enters the input opening to drive the sprinkler to repeatedly swing between the base members. The two base members respectively further have two supporting legs at opposite sides, a bottom side of each supporting leg engages with a connecting member, and the connecting member is pivoted with a grounding nail. An outer side of each supporting leg of the base members is provided with a containment space at a bottom side, and the containment space is configured for accepting the engaged connecting member.
