Description

"UTILITY CHAMBER AND ASSEMBLY"

FIELD OF THE INVENTION

The present invention relates to utility chambers, more particularly, though not solely, to in-ground utility chambers of the type for housing communications equipments, such as telecommunications equipment, and an assembly for such a utility chamber.

BACKGROUND TO THE INVENTION

Utilities such as power, electricity, water, telecommunications, gas and similar are often contained within, and ducted by, utilities. In many cases it is convenient to duct these utilities under the surface of the earth or a structure, for example a road, runway, footpath, a built up area (e.g. floor of a building or structure) or similar. The nature of such utilities requires periodic access, for example for maintenance.

The utility chambers are accessed via a hatch, or similar that lies flush with the surface the chamber is set into. The chambers can house junctions of the utility, or permit access thereto e.g. piped or wired utilities. As the utility chambers are located below the surface, with the access hatch flush with the surface (e.g. the surface of the road), they do not impede surface movement e.g. traffic flow. This enables the best location of the utility chamber. However, as a result the chamber, hatch and particularly the support for the hatch, must be sufficiently strong to support surface loads, e.g. traffic passing over or static loads placed thereon.

In addition, the upper surface of the chamber is set at a certain level, i.e. that of the surface. This is a further disadvantage. If further work is carried out at a later date (e.g. road resurfacing), this can leave the upper surface of the chamber lower or higher than the rest of the road surface. This will render an otherwise smooth surface bumpy. It is difficult to adjust the position of the frame to the new surface level without significant re-construction work, and possibly the removal and repositioning of the frame, if not the chamber also.

Further, existing utility chambers are typically manufactured of a form that is bulky, voluminous to transport, and the individual parts often heavy.

Existing utility chamber systems often also require that a hole be created in the ground, the utilities pared back from the hole (if a chamber exists already) in order to provide space for the replacement chamber to be inserted into the hole/cavity and then utilities reconnected to each other within the chamber.

It is therefore an object of the present invention to provide an in-ground utility chamber which will go at least some way towards addressing the foregoing problems or which will at least provide the industry or public with a useful choice.

In this specification where reference has been made to patent specifications, other external documents, or other sources of information, this is generally for the purpose of providing a context for discussing the features of the invention. Unless specifically stated otherwise, reference to such external documents is not to be construed as an admission that such documents, or such sources of information, in any jurisdiction, are prior art, or form part of the common general knowledge in the art.

Further aspects and advantages of the present invention will become apparent from the ensuing description which is given by way of example only.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

It would therefore be advantageous to provide a system which was easier to transport, less bulky, yet still relatively uncomplicated to construct. Additionally, it would be advantageous to provide for an in-ground utility chamber which was able to be assembled in-situ about an existing network of utilities, without a need to disturb the utilities during installation of the chamber.

This invention provides for a utility chamber having an in-ground application, and where multiple components are provided in forming the different assemblies to be connected with each other, and in provision of one upper collar type assembly being movable up and down relative to the lower assembly. In this manner, the upper assembly is height adjustable with respect of a lower chamber assembly. The upper collar type assembly is receivable of a cover or hatch/lid allowing for enclosure of the top of the chamber.

Additionally, the utility chamber provides for a utility accessway in a part of the lower assembly allowing for ducting into the chamber of utilities, such as communications equipment, including telecommunications gear, networking gear, or as a housing for other associated equipment.

Provision of a sub-surface or in-ground utility chamber assembled from multiple components according to this invention may further allow for a chamber to be assembled within a hole or subterranean position. For example, where an existing utility chamber is to be replaced or upgraded, the chamber (1) of the present invention may be assembled into its enclosed form about the existing utilities. This prevents or ameliorates the need for decommissioning of such in-ground utilities. The chamber (1) can, therefore, be assembled to surround the utilities and provide a protective housing.

Accordingly, and with reference to the accompanying figures, there is provided an in-ground utility chamber (1) comprising a first set of two or more components (2A, 2B) providing for an open topped lower-most region assembly (3). A second set of two or more components (4A, 4B) provides for an open-ended upper-most region assembly (5). The second set of components (4A, 4B) are engageable with, and height adjustable relative to, the first set of components (2A, 2B), the second set of components (3A, 3B) being positioned about the open top of the lower-most region assembly (3).

The open-topped lower-most region (3) is generally a chamber region. Such a chamber region provides a housing or enclosure for utilities.

The open-ended upper-most region (5) is generally a collar region. In various embodiments, the open-ended upper-most region extends as a collar, the collar being internally or externally surround of or about the open top of the open-topped lower-most region assembly. In an alternative, the collar may be of a sleeved configuration, sleeved to extend atop of or over and about, for example, the upstanding walls (19A, 19B) of the first set of components (2A, 2B) when assembled. Such a sleeved collar configuration is not specifically shown in the figures.

The open-ended upper-most region assembly (5) is of a height (6) equal to or less than the height (7) of the open-topped lower-most region assembly (3). Alternatively, the open-ended upper-most region assembly (5) is of a height (6) less than the height (7) of the open-topped lower-most region (3).

The chamber as claimed in any one of claims 1 to 6, wherein one or more releasable fasteners (8) engage the second set of components (4a, 4B) with the first set of components (2A, 2B), said releasable fasteners (8) adjustable such that said second set of components (4A, 4B) are re-positionable between raised or lowered positions relative to the first set of components, such as for example the raised position as shown in Figures 1, 2, 6, or the relatively lower position as shown in Figures 2, 3, 7, 10.

It will be appreciated other height positions can be achieved through the release of releasable fasteners (8) that otherwise retain the second set of components formed as the open-ended upper-most region assembly from an existing height position, and a readjustment of relative height can take place, before the fasteners (8) are utilised again to re-engage with the second set of components and perform their retaining/retention function in a different relative height positioning.

The second set of components (4A, 4B) formed as the open-ended upper-most region (5) can be fixed by said releasable fasteners (8) at a first height. For example, a raised or higher position as shown by Figures 1, 2, 6, or a lower position as shown by Figures 2, 3, 7, 10, or may be at positions in between, relative to the first set of two or more components (2A, 2B) formed as the open-topped lower-most chamber region (3) is achievable. The fasteners (8) used are releasable and re-fastenable to allow for a repositioning of the relative height of the second set of components (4A, 4B) forming upper assembly (5) .

The second set of components (4A, 4B) formed as the open-ended upper-most region (5) are height adjustable relative to the first set of components (2A, 2B) formed as the open-topped lower-most chamber region (3).

Figure 1 illustrates a chamber (1) without a cover (12) in place, and where the second set of components (4A, 4B) forming the upper-most region (5) is in a raised position.

Further facilitating travel of correct (aligned) height adjustment, the second set of components formed as the open-ended upper-most region further comprise a channel or guide (10) receivable of a releasable fastener (8). Such a channel or guide (10) provides a defined pathway (for example, along the length and direction of channel or guide (10)) for travel relative to the first set of components formed as the open-topped lower-most chamber region. In various embodiments, the channel or guide (10) is provided as slide or may alternatively be of a telescoping rail.

The channel or guide (10) may allow for some lateral angulations of the releasable fastener (8) upon the channel or guide (10). In this manner, there can be provided a height adjustable second set of assembled two or more components, and which may allow for a differential height along the length of the assembled upper-most region according to a base reference of height from the base or floor of the lower-most region. That is, the upper-most region may be adjusted to be of a greater height at one end of the chamber compared to the other end of the chamber to account for situations where the chamber is not seated on a level surface or where the exposed surface of the chamber with cover (12) is otherwise not flush or aligned with the surrounding surface (e.g. roadway, pavement, turf).

The first set of components can additionally includes one or a series of stops (9) to limit travel of said second set of components formed as the open-ended upper-most region. For example, the stops (9) provide or impose a lower limit or maximum lowered position of travel or height adjustment of said second set of components (4A, 4B) formed as the open-ended upper-most region (5) relative to the open-topped lower-most region (3).

Figures 2, 3, 7, 8, 10 show the open-topped upper-most region (5) imposing itself upon such stops (9). The stops (9) can be of any shape or configuration, but generally are protuberances or projections extending from the first set of components. The stops (9) are provided in a path of travel of the second set of components formed as the open-ended upper-most region.

In forming the upper and lower assemblies, the components (of each set) are engageable with each other via connecting members (11).

Figures 4 and 5 illustrate a chamber (1) in its separate and partially assembled form. For example, Figure 4 illustrates a cover (12) which is to be seated upon the region indicated by numeral 21, formed by assembly of the second set of components (4A, 4B). In this same figure, the first set of components is not yet assembled, but clearly shows the connecting members (11) used to do so, as well as the stops (9) for imposing a limit on the height travel of the upper-most region (5).

Figure 5 also illustrates a cover (12) to be seated, but where the upper-most region (5) components (4A, 4B) are shown in their separate parts, and where the lower-most region (3) is shown also in separate parts, and where the utility accessway (14) allows for use of an enclosing material or member (24) to close off the accessway (14) from environment (e.g. of soil, water or other debris) that may otherwise enter the chamber (1).

The accessway (14) and enclosing material or member (24) can be shaped or configured for receipt of piping, pipe-work, ducting (e.g. as shown by numeral 25) or other devices carrying utilities into the chamber (1).

Figures 6 and 7 show an embodiment of a chamber (1) according to this invention in an assembled form (where a cover (12) may be subsequently put into position). Utility accessway (14) is shown in its closed form using a member (24), such as a shaped aluminium sheet, or alternatively may be a polymeric material which can be appropriately sealed to the chamber (1) to prevent ingress of liquid (e.g. water) into the chamber. The ducting (25) should also be appropriately sealed to the member (24) for water-tightness. The member (24) can be provided as a plastic or polymer component for ease of cutting or sectioning as required to allow an opening for the ducting (25) into the chamber.

Figure 8 is an transverse cross-sectional view of a chamber (1), showing utility accessway (14), connecting member (11) and relative positioning of a cover (12) in place, while an upper-most region assembly (5) is in a lower-most position, as determined by the length and path of travel by the channel or guides (10) and stops (9). Figure 9 is a longitudinal cross-sectional view of a chamber (1), showing similar detail to that of figure 8, with cover (12) in place.

Figure 10 illustrates a chamber (1) in an in-situ position in the ground (i.e.

subterranean) and where the upper-most region (5) has its exposed surface level or flush with the ground, ready to receive a cover (12). Also shown is a cut-away view showing the positioning of the chamber (1) in the ground with relevant ducting (25) entering the chamber (1) through utility accessway (14). A member (25) is used to seal off the utility accessway and prevent ingress of liquid into the chamber (1).

The connecting members (11) enable assembly of the respective first and second sets of components (2A, 2B and 4A, 4B), and between the components of the first and second sets of components. Such connecting members (11) can comprise or include one or more of: threaded fasteners (e.g. nut and bolt, screw), pivot fasteners (e.g. hooked latch), complimentary projections and recesses (e.g. male protuberance and female recess receivable of male, pin and slot).

It will be appreciated various other forms of connections may be made, sufficient to enable the components 2A, 2B to be connected to each other in an engaged manner, and similarly, to enable the components 4A, 4B to be connected to each other in an engaged manner.

More specifically, the components engageable with each other are the components of the first set of components forming the open topped lower-most chamber region assembly. And, the other set of components engageable with each other are the components of the second set of components forming the open-ended upper-most region assembly.

In providing such a utility chamber 1, the second set of components formed as the open-ended upper-most region is receivable of a cover (12). Such a cover (12) provides enclosure of said in-ground utility chamber. The cover (12) is a lid to the open-ended upper-most region.

The cover (12) is fastenable to or with said second set of components formed as the open-ended upper-most region. The cover (12) is fastenable or attachable to the, or at least a part of the, second set of components. In this manner, the cover (12) can be held in a seated position.

In another embodiment, the cover (12) provided is of a lockable type, using a lock (23). For example, using a system for engaging the cover (12) with a component or components of the second set of components in a more securely affixed manner may provide for a number of benefits. For example, a quarter turn latching system, or cover set system, such as that described by PCT/IB2011/054256, the contents of which are herein incorporated fully by reference, can be used as a cover (12) fastening of locking system.

The cover (12) also provides (once removed from its seated or in-situ position) for an accessway (generally indicated by numeral 13) into the open-ended upper-most region and the open-topped lower-most chamber region.

The open-topped lower-most region further comprises an opening, such as a utility accessway (generally indicated by numeral 14). The utility accessway (14) is configured for receipt of in-ground utilities (e.g. communications equipment, such as

telecommunications equipment, fibre optic cables/lines, power cables/lines, or other equipment or infrastructure or networking gear that can be located in a subterranean manner).

The at least two side wall portions (20A, 20B) of the second set of components (4A, 4B) being yet further engageable with the upstanding side wall portion or portions (2A, 2B) of the first set of components extending or extended from said at least two floor portions (18A, 18B).

The connecting members (11) are provided on at least the floor portions (18A, 18B) and upstanding side wall portions (19A, 19B) of the first set of components (2A, 2B). The connecting members (11) provide for connection of adjacent components of the two or more components. Connecting members (11) can also be provided on adjacent side wall portions of the at least two side wall portions (19A, 19B) of the second set of components.

As discussed above previously, a channel or guide (10) can be provided. Such a channel or guide can be more specifically provided upon at least at least one side wall portion (20A, 20B) of the second set of components (4A, 4B). The channel or guide (10) extends generally from the upper perimeter region (21) to a lower end (22) of the side wall portion.

The stop or stops (9) mentioned above can be provided upon the upstanding side wall portions (19A, 19B) of the first set of components (2A, 2B).

The utility accessway (14) discussed above can be provided in or through an upstanding side wall portion (19A, 19B) of the first set of components (2A, 2B).

According to the above embodiments, first set of components (2A, 2B), or second set of components (4A, 4B), or cover (12) (or combinations or all of these) can be constructed of aluminium.

In a further embodiment, such an in-ground utility chamber (1) can comprise of a first set of components (2A, 2B) providing for an open-topped lower-most chamber region (generally indicated by numeral 3). The first set of components (2A, 2B) being defined by at least two floor portions (18A, 18B), where each said floor portion is associated with at least one upstanding side wall portion or portions (19A, 19B) extending therefrom. The at least two floor portions (18A, 18B) and side wall portion(s) (19A, 19B) are engageable with each other in forming the lower-most chamber region (3). The side wall or walls portion (19A, 19B) defining the open top of the lower-most chamber region (3), and a second set of components (4A, 4B) providing for an open-ended upper-most collar region (generally indicated by numeral 5). The second set of components (4A, 4B) is defined by at least two side wall portions (20A, 20B), where the side wall portions (20A, 20B) engageable with each other in forming said open-ended upper-most collar region. The side wall portions (20A, 20B) when engaged with each other further define an upper perimeter region (21) that is receivable of an enclosing cover (12). The at least two side wall portions (20A,

20B) further being engageable with the upstanding side wall portion or portions (19A, 19B) that extend upwards from the at least two floor portions (18A, 18B). And, where the second set of components (4A, 4B) are adjustably engageable with the upstanding side wall portion or portions (19A, 19B) extending from the at least two floor portions (18A, 18B), and being adjustable such that the second set of components (4A, 4B) are height positioned or positionable relative to the first set of components (2A, 2B).

In yet a further embodiment, it will be appreciated a method is provided for assembly of such a utility chamber (1). Such a method of assembling an in-ground utility chamber comprises providing the first and second sets of components (2A, 2B, 4A, 4B) as described above. Then, engaging each of the first set components to each other to form the open-topped lower-most region assembly (3); and, engaging each of the second set of components (4A, 4B) to each other to form the open-ended upper-most region assembly (5). Following this, the method then requires engaging the assemblies of the open-topped lower-most region (3) and open-ended upper-most region (5) to each other. Adjusting the relative height of the open-ended upper-most region (5) relative to the open-topped lowermost region (3) according to a user required height position, such as the level of the surrounding turf or ground or pavement surrounding the recess in the terrain that the chamber (1) is to occupy.

It will be appreciated, the present invention provides for an in-ground utility chamber of a type that allows for height adjustment of an upper region. Such height adjustment ability advantageously allows for a refinement of the top surface level of the chamber (i.e. when cover is in-situ) to be flush with the surrounding surface. For example, the surrounding surface may be a road surface, or pavement or turf. Providing a utility chamber having an exposed surface that is flush with the surrounding level is particularly useful.

Advantageously, the chamber of the present invention is preferably has an exterior surface, for example, the exterior surface of the upstanding side walls, which is

substantially smooth. In an even more preferred form, such exterior surfaces or outside surfaces of the one or more components forming the upstanding side wall portions are substantially devoid of ribs or other structures which may otherwise impede upon backfilling or compaction of backfill about an upper region of the first set of one or more components, or an upper region of the second set of one or more components, or both (for example where a height adjustable chamber is provided). In other embodiments, the chamber of this invention can have a floor provided as a separate component or part which can be connected or engaged to or with the other components or parts forming the chamber. Alternatively, the floor of the chamber can be provided as an integral part of an upstanding wall portion, such that the number of overall components of the chamber is yet further reduced.

In some situations, an installer may prefer for a separate floor component, rather than an integral floor, or vice versa.

In a further preferred form of this invention, aside from the member (24), the chamber itself (and optionally the cover or lid) is provided as aluminium, for example a cast or formed aluminium chamber and components. In this manner, particular

disadvantages of plastic chambers are overcome. For example, plastic chambers are lesser strength or capability to withstanding weight loading, they may also fail (whether partially or wholly) over time due to UV degradation, and are often subject to other partial failures or breaks or cracks due to mechanical implements impacting such a plastic chamber (for example, a lawn mower may chip or crack a plastic collar or rim or lid of a plastic chamber, thereby impacting on the mechanical integrity and usefulness of such a chamber). Plastic chambers also fail when subjected to higher temperatures, for example in a fire situation. Plastic chambers do not have the required strength characteristics required by industry and the side walls may collapse when external pressures (e.g. environmental hydrostatic pressure or soil/earth pressure) is exerted upon a plastic chamber side wall - yet another reason why a plastic chamber is likely to fail. Aluminium provides a vastly superior product over that of a plastic chamber, yet remains relatively light in weight, yet with significant strength and impact loading physical characteristics, as well as ability to withstand fire.

In other forms, the chamber of this invention provides for the second set of components which surround or envelop an outer perimeter defined by the first set of components. In this manner, where the second set of components are provided for such a chamber, the second set of components provide for an outer layer of protection to the chamber. Further, as the second set of components are located about an exterior or outside surface of the perimeter defined by the first set of components, such second set of components help to hold back backfill materials (e.g. soil, gravel, stone, concrete) from abutting or entering the chamber. In contrast, some plastic chamber devices may have any such extensions provided to on an interior surface of the chamber, which do not help prevent compaction materials (or other surrounding materials, e.g. water) from entering such a chamber.

In another embodiment of this invention, there is provided a utility chamber comprising a first set of two or more components that together provide for an open-topped chamber region or lower-most region assembly. Such components may be brought together in their split or separate part form and assembled to form a chamber. The floor for such a chamber can be provided as one of the separate components or parts of the first set of components, or may be provided as an integral part of upstanding walls forming the open-topped chamber. Advantageously, a series of engaging members can be used to engage each of the component parts together, for example quick connecting devices, such as a latch or hook-style latch. In such an embodiment, upstanding wall portions defined the height of the chamber from the floor. Such a height being pre-determined or fixed according to the size of the upstanding walls.

In a variation, such a chamber may additionally utilise a second set of two or more components providing for an open-ended collar region or upper-most region assembly. Such a second set of components are engageable with, and are provided such that they are height adjustable relative to, the first set of components. The second set of components to be positioned about the open-top of the lower-most region assembly, preferably located about an exterior surface of the upstanding walls or first set of components.

In another variation, the second set of components may not be height adjustable relative to the first set of components, but may instead be a fixed height extension (e.g. 50) to the overall height of the chamber from a floor. In this manner, a fixed height chamber can be increased in height to match or accommodate either a deeper cavity into which the chamber is to be inserted, or where the ground level is to be raised, without raising the chamber itself from its in-situ position, the extension can facilitates the higher level for receiving of a cover or lid.

In yet in even other forms, where an extension of a relative height adjustability of a second set of components still does not match a higher ground level, a plurality of extensions or other forms of extension can be provided to ensure there remains a chamber having upstanding side walls extending up to the frame for receiving of the cover or lid, such upstanding side walls being discontinuous (i.e. comprised of separate parts).

In another form, the second set of components can be engaged or connected to or with the first set of components in a fixed manner, such that a chamber is provided having a first depth determined by the distance from the floor to the top of upstanding side wall portions, and then that first depth or height can be increased by connection of the second set of components to provide a chamber of a second depth or height from the floor to the top of the second set of components.

Figure 11 illustrates one form of a fixed height chamber comprising a first set of components, a cover or lid. In such a chamber there may be an integral floor portion, such a floor portion integral with the upstanding wall portions, or a separate floor (such as shown in figure 13).

Figure 12 is a partially exploded perspective view of an alternative chamber to that of figure 11. Such a chamber comprises an extension capable of being sitting atop the upper region of the upstanding walls or first set of components. Figure 11, visible is a connecting member in the form of a hook latch for connecting or engaging one end of the first set of components together.
