DETAILED DESCRIPTION

[0022] The specific details of the single embodiment or variety of embodiments described herein are set forth in this application. Any specific details of the embodiments are used for demonstration purposes only, and no unnecessary limitation or inferences are to be understood therefrom.

[0023] Before describing in detail exemplary embodiments, it is noted that the embodiments reside primarily in combinations of components related to the system. Accordingly, the device components have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present disclosure so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.

[0024] In general, the embodiments described herein relate to a valve box riser extension utilized to raise the lid of a valve box such that the lid remains accessible to allow access to the components stored within the valve box. The valve box riser extension is positioned between the valve box lid and the valve box. Further, the valve box riser extension is stackable to allow two or more valve box riser extensions to be stacked on top of one another as required to keep the lid at or above the ground level.

[0025] Valve boxes allow for routine maintenance of the irrigation system while protecting the irrigation components housed therein. Often, valve boxes can be installed which are too small for maintenance to be performed on the internal components. This results in the valve box needing to be dug out of the ground for maintenance to be completed. Another common problem is using a valve box made of materials not resilient enough to withstand the elements, pressure applied from the ground substrate, or withstand degradation over time. Further, valve boxes may become buried due to shifts in the ground substrate, or a heavy object being placed (permanently or temporarily) over the top of the valve box. This results in the valve box being driven deeper into the ground than it is designed and restricting access to the valve box. During installation, if the foundation of the valve box is not stabilized, the valve box may sink into the ground over time. It is important for the valve box to be measured and properly fitted into the ground to ensure the valve box remains accessible. Otherwise, the valve box must be dug out of the ground and the foundation fortified to fix the problem.

[0026] As used herein, the term “valve box” is utilized to conceal and protect the valves, fittings, wires, manifolds and other components which are necessary to form a functional irrigation system. The valve box is constructed of a resilient material (often a rigid plastic or other rigid materials such as concrete, wood, and metals) to protect the irrigation components housed therein. The valve box includes a housing which is buried at least partially in the ground and is dimensioned to conceal and protect the valves, fittings, wires, manifolds, etc. A removeable lid covers the opening at the top of the valve box. The lid is accessible from the top of the box and allows for access to the irrigation components during maintenance. The valve box and lid protect the irrigation components from vandalism, the elements (e.g., excessive debris, moisture, etc.), and damage caused by lawn mowers and string trimmers.

[0027] As used herein, the term “irrigation components” refers to any combination of components which operate the irrigation system including valves, fittings, wires, and manifolds.

[0028] FIG. 1 illustrates an exploded view of the valve box 100, the valve box riser extension 102, and the valve box lid 104. The valve box 100 is positioned within the ground during installation of the valve box 100 and/or the irrigation components which are housed therein. The valve box 100 include a bottom 106 which rests upon the foundation formed by the ground sediment. The foundation may be supplemented with rock or other material to prevent the valve box 100 from sinking over time. The top edge 108 of the valve box 100 is positioned at about ground level to allow for access to the interior cavity of the valve box and irrigation components housed therein. The extension riser 102 is positioned between the valve box 100 and the valve box lid 104. The valve box lid 104 releasably engages with the valve box riser extension 102, such that the valve box lid 104 can be selectively removed to access the irrigation components stored within the valve box 100. The valve box riser extension 102 includes a bottom portion 110 and a top portion 112 separated by a rim 114. Bottom portion 110 is attached to the top edge 108 of the valve box 100 while the top portion 112 is releasably engaged with the valve box lid 104. The rim 114 prevents the valve box riser extension 102 from being pulled out of the ground when removing the valve box lid 104.

[0029] One skilled in the arts will readily understand that the rim 114 may not be tapered. However, a tapered shape may provide a better fit between each component.

[0030] In some embodiments, the bottom portion 110 of the valve box riser extension 102 is releasably engaged with the valve box 100 to allow for the selective attachment and removal of the riser box rise extension 102 with the valve 100. In such, the valve box riser extension 102 can be fitted to an existing valve box 100 which has previously been positioned in the ground.

[0031] FIG. 2 illustrates a side elevation view of the valve box riser extension 102, according to an exemplary embodiment. The valve box riser extension 102 includes the bottom portion 110, the top portion 112 and the rim 114 as discussed hereinabove. The rim 114 is positioned about the perimeter 200 of the exterior surface 202 of the valve box riser extension 102. The rim 114 is constructed as an inverted wedge having an acute incline angle surface lip portion 204 having a first circumference 206 which is larger than the circumference of the valve box lid. The rim includes an interior lip which allows for additional valve box riser extensions 102 to be stacked on top of one another as illustrated and described in FIG. 4.

[0032] FIG. 3 illustrates a top plan view of the valve box riser extension 102 in an exemplary embodiment. The valve box riser extension 102 includes an exterior surface 202 and an interior surface 300. An interior ledge 304 allows the valve box lid or additional valve box riser extension 102 to rest thereon. The valve box riser extension 102 is constructed having a sidewall 306 width sufficient to prevent bending or other malformation of the valve box riser extension 102 and supports the structure of the valve box when positioned thereon.

[0033] FIG. 4 illustrates a side elevation view of the valve box riser 102 in a stacked configuration wherein a first valve box riser extension 102 and a second valve box riser extension 400 are engaged with one another. The stackability of the valve box riser extensions 102 allow for a plurality of valve box riser extensions to be stacked to accommodate valve boxes which have sunk into the ground to a depth too deep for a single valve box riser extension 102. In such, those servicing the valve box and irrigation components therein can continue to be accessed without the need to dig out the valve box and fortify the foundation underneath.

[0034] Many different embodiments have been disclosed herein, in connection with the above description and the drawings. It will be understood that it would be unduly repetitious and obfuscating to literally describe and illustrate every combination and subcombination of these embodiments. Accordingly, all embodiments can be combined in any way and/or combination, and the present specification, including the drawings, shall be construed to constitute a complete written description of all combinations and subcombinations of the embodiments described herein, and of the manner and process of making and using them, and shall support claims to any such combination or subcombination.

[0035] It will be appreciated by persons skilled in the art that the present embodiment is not limited to what has been particularly shown and described hereinabove. A variety of modifications and variations are possible in light of the above teachings without departing from the following claims.
