Description
ENCLOSURE FOR A UTILITY METER AND/OR CONTROL VALVE This invention relates generally to enclosures for utility meters and/or control valves, for example water, gas or electric supply meter and/or control valves. More specifically, s although not exclusively, this invention relates to an implantable water meter and control valve enclosure to be buried in the ground, for example those commonly referred to as boundary boxes, or in a wall.
Boundary boxes are often used to enable water meters to be housed below the surface of io the ground. This is done for a number of reasons including, for example, to protect the meter and/or pipes connected to it by burying them deep enough to avoid freezing of water therein or simply to enable a meter to be contained beneath a public road or footpath while enabling the meter to be accessed for reading.
is Such boundary boxes are generally installed at a predetermined position in the ground where the pipes have already been laid. Conventional boundary box designs include fixed fluid connections to which the pipes are to be connected. This can cause problems during installation, for example where the relative position and orientation of the laid pipes do not readily align with the fluid connections. One proposal for solving this misalignment is to provide connections with a relatively complex and expensive assembly that permits so-called eye ball' adjustment.
It is therefore a first non-exclusive object of the invention to provide a boundary box that at least mitigates the issues described above. It is a further, more general non-exclusive object of the invention to provide an improved boundary box. It is a yet further non-exclusive object of the invention to provide a boundary box that may be configured or adapted by a user.

The diameter of the lower cylindrical wall 161 is less than that of the upper cylindrical wall 160 and the annular portion 162 includes a depression 163 is with a plurality of drain holes 163a extending therethrough at a position that is radially between the walls 160, 161. The upper cylindrical wall 160 and the intermediate annular portion 162 together define a lid receptacle 164 within which the lid 104 is received. The lower cylindrical wall 161 and the intermediate annular portion 162 together define a body receptacle 165 within which the upper, inner telescopic member 130 of the body 103 is received. Thus, the drain holes 1 63a extend from the floor of the lid receptacle 164 to the outside of the enclosure 100 when the enclosure 100 is in an assembled condition, while the depression 163 functions as a trench or gulley interconnecting the drain holes 163a.
In this embodiment and as shown more clearly in Figures 9 and 10, the lid receptacle 164 includes a recess 166 with an identification tag 167 in the form of three alphanumeric arrays of seven projecting elements 167a, which are selectively removable to create a visual identifier for the enclosure 100.
The enclosure 100 according to this embodiment further includes an antenna 108 received within a cylindrical recess 180 in the upper housing 106 to enable automatic reading of a meter contained in the enclosure 100. The upper housing 106 includes a cylindrical antenna housing 181 depending from the intermediate annular portion 162 that houses the recess 180, which is accessible from an aperture 182 in the intermediate annular portion 162. The aperture 182 is sealingly closable by a closure element 183 that is releasably securable to the aperture 182 to cover the antenna 108. The upper housing 106 also includes a locating slot 184 that extends axially along an internal surface of the upper housing 106 and receives a filament portion 108a of the antenna 108.
The body 103 includes a pair of telescopic hollow tubular members 130, 131 each with a pair of sealing lips 132, only one of which is shown. The sealing lip 132 of the outer telescopic member 131 extends inwardly to seal against the outside surface ot the inner s telescopic member 130, while the sealing lip (not shown) of the inner telescopic member extends outwardly to seal against the inside surface of the outer telescopic member 131. Thus, the two members 130, 131 are telescopically movable to adjust the overall height of the enclosure 100 in a sealing manner. The upper, inner telescopic member is received in and engages with the upper housing 106. The lower, outer telescopic io member 131 engages with the lower housing 107 by an interlocking bayonet-type fitting that is provided by four equispaced downwardly extending hook projections 133 that are received in gaps 170 in an outwardly extending peripheral mounting flange 171 of the lower housing 107.
is The telescopic members 130. 131 in this embodiment include two layers formed by coextrusion. Figure 16, which corresponds to part section A-A of Figure 5, illustrates the two layers 131 a, 131 b of the outer, lower telescopic member 131. The inner layer 131 a is of a light colour, off-white in this embodiment, and the outer layer 131b includes a darker colour than the inner layer formed with recycled material. Providing an inner layer with a light colour improves visibility and/or light reflection to aid or facilitate reading of the meter and the visibility of the meter and valve 2.
The lower housing 107 includes a base 172, an outer wall 173 extending upwardly from a peripheral portion of the base 172 and an intermediate floor 174 between the base 172 and the body 103. The flange 171 extends outwardly from the wall 173 and defines an upper sealing portion with a circumferential groove that receives an 0-ring 175 tor receipt into and sealing engagement with an internal surface of the lower, outer telescopic member 131. It will be appreciated that the floor 174 and an upper portion of the wall 173 together define the space or volume within which the meter and valve 2 are received.
The floor 174 includes a pair of holes 1 74a, 1 74b and a non-return valve 176 and the wall 173 has a pair of cutouts 173a, 173b between the base 172 and the floor 174.
The non-return valve 176 in this embodiment is in the form of a tubular element with a flattened lowermost end that is fluidly and sealingly connected to a drain hole 177 in the floor 174. The non-return valve 176 allows water contained in the enclosure (e.g. that has seeped in over time) to drain out but inhibits water from flowing into the enclosure 100.
In this embodiment, the utility meter and control valve 2 are formed integrally with the pivot joints 50a, 50b via a respective pipe portion 20, 21. The pipes 5a, 105a, 5b are pivotally connected to the pivot joints 50a, 50b each of which seals off and passes through a respective one of the holes 174a, 174b in the floor 174 of the lower housing s 107. The pipes 5a, 105a, 5b extend downwardly from the floor 174 and have an intermediate bend 151a, 51b with a transverse section that passes through a respective one of the cutouts 173a, 173b and out of the lower housing 107. One of the pipes 105a includes a push fitting 150a formed integrally with the free end of its transverse section, which fitting 150a includes a toothed annulus and 0-ring seal received in a conical body io for allowing insertion of a further pipe (not shown) therein but preventing or at least inhibiting its removal.
The cutouts 173a, 173b are shaped and sized to allow the pipes 5a, 105a, 5b to pivot about the pivot joints 50a, 5Db and holes 174a, 174b to adjust the orientation of the is transverse section of the pipe 5a, 105a, Sb. In this embodiment! the cutouts 173a, 173b are also shaped and sized to allow the pipes 5a, 1 05a, 5b to pivot by 60 degrees, thereby providing a combined variation of 120 degrees relative to one another.
Referring now to Figures 21 to 23, there is shown an alternative non-return valve in the form of a diaphragm or umbrella valve 276 with a plurality of holes 277 and a flexible diaphragm 278. The diaphragm 278 includes a flat plate-like portion 279, a spacer portion 280 and a tapered hollow spigot portion 281 extending from the spacer portion 280 and having a retaining bulge 282 adjacent its free end. The spigot portion 281 is received in and engages a central hole 277a and is retained therein by the retaining bulge 282. The valve also includes a shroud 283 surrounding the diaphragm 278 and extending downwardly from the bottom of the enclosure 100.
In use, water (not shown) contained in the enclosure 100 passes through the holes 277 and force the diaphragm 278 down away from the holes 277 to allow the water to flow out of the enclosure 100. However, if the water level in the ground within which the enclosure is located rises to the level of the non-return valve 276, the diaphragm is urged toward a closed position in which the diaphragm 278 covers the holes 277 and prevents the passage of water through the holes 277.
Referring now to Figures 24 to 29, there is shown the lower part of an implantable boundary box enclosure 300 according to a third embodiment for housing a utility meter and control valve, which is similar to the enclosures 1, 100 according to the embodiments described above, wherein like references depict like features that will not be described further herein. The enclosure 300 according to this embodiment includes a base 330 that has a conical-shaped floor 332 that tapers towards the non-return valve 276. In use, water (not shown) contained in the enclosure 300 drains towards the non-return valve 276 s and out of the enclosure 300.
The tapered floor 332 includes a pair of holes (not shown) through which pivot joints 50a, 50b pass. Pipes 5a, 5b are pivotally connected to pivot joints 50a, 50b and extend downwardly from the tapered floor 332 and through cutouts 331a, 331b in the base 330.
io In this embodiment, the pipes 5a, 5b extend out of the enclosure 300 longitudunally relative to the enclosure 300, allowing the pipes 5a, Sb to be filled from underneath the enclosure 300.
The base 330 also has a skirt 340 which improves the stability of the enclosure when is buried in the ground.
In this embodiment, the base 330 is designed to receive an upper tubular member 331 that is telescopically moveable relative to the base 330 to allow adjustment of the overall height of the enclosure 300 in a sealing manner. The base 330 engages with the upper tubular member 331 by an interlocking snap fit connection that is provided by four equispaced moulded C shaped protrusions 350 in the base 330 that are received in gaps or holes 351 in the upper tubular member 331.
As shown in Figure 27, the C' shaped protrusions 350 are moulded in the base 330 forming indentations on the inside of the base 330 and protrusions on the outside of the upper tubular member 330.
In use, the upper tubular member 331 is pushed into the base 330 and twisted to bring the C' shaped protrusions 350 of the base 330 into alignment with the gaps or holes 351 in the upper tubular member 331, as shown in Figure 28. When in the correct position, the C' shaped protrusions 350 snap into the gaps or hole 351 holding the upper tubular member 331 and base 330 in position as shown in Figure 29. The upper tubular member 331 can be removed from the base 330 by firmly pulling the upper tubular member 331 and base 330 apart.
It will be appreciated by those skilled in the art that several variations are envisaged without departing from the scope of the invention. For example, the enclosure 1 may be provided without the pipes 5a, 5b and/or without the pivot joints 50a, 50b and/or in kit form. The enclosure 1 may be split into two parts, for example a lower part or portion that includes the base 30, floor 32 and some or most but not all of the outer wall 31 and an upper part or portion that includes an extension of the outer wall 31, for example a tubular portion that interconnects the lower part or portion with the lid 4. It is also envisaged that s the upper pad or portion may be a telescopic tubular assembly that enables adjustment of the height of the enclosure 1. The non-return valve 176 may incorporated a fold or kink in the or a flattened portion to more effectively prevent or inhibit backflow of fluid into the enclosure.
It will also be appreciated by those skilled in the ad that any number of combinations of the aforementioned features and/or those shown in the appended drawings provide clear advantages over the prior ad and are therefore within the scope of the invention described herein.
