Description
Pole assembly
Field of the invention
[0001] The present invention relates to street poles suitable for supporting street lighting, displaying flags, banners or signage, conveying electricity, telecommunication boxes, solar panels and related equipment. The invention has been developed primarily for use as a multiple use pole and will be described hereinafter by reference to this application.
Background to the invention
[0002] The following discussion of the prior art is intended to present the invention in an appropriate technical context and allow its advantages to be properly appreciated. Unless clearly indicated to the contrary, however, reference to any prior art in this specification should not be construed as an express or implied admission that such art is widely known or forms part of common general knowledge in the field.
[0003] In the field of elongated support structures and in particular street poles or lighting, there have been significant changes made in the manufacture and instalment of such street and outdoor lighting poles.
[0004] Previously, support structures for street lighting etc. were constructed from timber or as a unitary steel tubular body. Architectural design and aesthetic demand has led to the development of a wide range of options for such street lighting.
[0005] With urban designers requiring the need for pole mounted lighting, traffic control, CCTV, banners, signage, public warning, communication, environmental monitoring, pedestrian management and many other applications in public areas it was inevitable that a streetscape would become cluttered with myriad of different poles delivering these services. Not only has this become visually unsatisfactory in many places but also it has created a maze of obstructions in pedestrian areas using up valuable civic space.
[0006] This has a new generation of light poles that delivers to the community an effective solution to the growing number of single purpose poles that are sprouting in the urban environment.
[0007] In particular the applicant has developed its Multipole™ and Multipole Solar™
products that deliver an aesthetically pleasing all aluminium multi-function pole that can provide a flexible secure home for many of the services required in the streetscape. In addition the poles can be the basis for the provision of public amenities such as bike racks, bus shelters, water bubblers and seats.
[0008] Early generations of these poles relied on a steel core clad in aluminium decorative cladding however recent developments have removed any reliance on steel by designing a pole based on the Applicant’s own extrusion technology.
[0009] This provides a number of significant advantages including improves sustainability since aluminium poles have a smaller carbon footprint, reduce installation costs as the weight of aluminium poles is substantially less than steel poles and the composite arrangement of producing the pole in separate connectable tubes reduce transport costs, low maintenance costs and resistance to graffiti, a safer pole due to its inherent energy absorbing nature of aluminium as compared with steel, excellent strength and ability to withstand severe environmental conditions, aesthetic advantages since there are no welded joints in the extruded aluminium pole section (such welded joints also provide a weakness in conventional steel poles) as well as the ability to produce tracks or channels in the aluminium extrusion to allow installation of accessories at various heights over the pole.
[0010] Currently, for costs and aesthetic reasons, aluminium poles are becoming more popular. Some such poles are provided with an extruded aluminium base section with a first cross-section shape and size, and a mast of second cross-section shape and size (preferably smaller than said first cross-section) connected to and supported by the mast. The lower supporting mast section it sometimes provided with flutes, reabsorbed channels. These ribs have multiple functionality including aesthetics, the ability to add accessories, etc. but they also serve the purpose of strengthening. As it will be understood by persons skilled in the art, previously constructed steel poles did not require such strengthening ribs since steel is stronger in a conventional tube. Aluminium on the other hand, can be extruded in quite complex cross-section which are both strong and light weight.
[0011] Generally, to install or mount items like luminaires, banners, signs, telecommunication boxes or other electronic devices to the pole, it is necessary for a worker in a cherry picker or other lift device to handle the item from above and fasten it to the pole in situ. This can be difficult to perform and there is a risk of the item being dropped, damaging itself or injuring a worker below. Moreover, the task is time consuming, inconvenient and
inefficient, increasing installation costs in time and manpower. This problem also occurs when the item is to be removed or replaced.
[0012] It is an object of the present invention to overcome or substantially ameliorate one or more of the disadvantages of prior art, or at least to provide a useful alternative. It is an object of the invention in at least one preferred form to provide a pole with a convenient and safe system to install, replace or remove modules.

[0039] It will be appreciated that this airflow advantageously assists to control (e.g. cool) the temperature inside the housing and mast, including the equipment modules. For example, the airflow can be used to vent or exhaust warm or hot air, created from heat generated by the equipment modules, out of the mast via the mast vent opening. In addition, the air flowing internally through the housing can pass over the equipment modules, further assisting to control the temperature (e.g. cool these modules).
[0040] In some embodiments, cladding is provided to enclose the housing. Preferably, the cladding is attached to one or more of the support elements. In some embodiments, the cladding includes a plurality of cladding panels. Preferably, each cladding panel is configured to complement the shape of the base. In some embodiments, each cladding panel is substantially planar. In some embodiments, each cladding panel is curved or arcuate in shape. In some embodiments, each cladding panel is secured to one or more of the support elements by one or more fastening elements such as, for example, screws which pass through holes in the cladding panels and threadingly engage the respective support element.
[0041] In some embodiments, each cladding panel is mounted to the respective support elements such that each cladding panel is spaced (radially) outwardly from the base, thereby to create an opening through which air can flow into the interior of the housing / pole assembly. In some embodiments, a spacer is arranged between each cladding panel and the respective support elements, thereby to facilitate mounting of each cladding panel outwardly of the base. In some embodiments, one or more structural element is mounted to the base such that a least of portion of the respective structural element sits outwardly of the periphery of the base, thereby to facilitate mounting of each cladding panel outwardly of the base. Preferably, each
structural element is mounted to the base such that a least of portion of the respective structural element sits outwardly of the periphery of the base. In some embodiments, one or more, preferably each, structural element is mounted to the base such that the distance that each panel sits outwardly of the periphery of the base is in the range of 5 mm to 50 mm, preferably 10 mm to 40 mm, more preferably 20 mm to 30 mm. In some embodiments, a distance of around 30 mm is preferred.
[0042] In some embodiments, one or more (preferably each) cladding panel is mounted to the respective support elements such that the lower end of the respective cladding panel sits, or is spaced, above the bottom or lowermost surface of the base, thereby to create an opening through which air can flow into the interior of the housing / pole assembly. In some embodiments, one or more, preferably each, structural element is mounted to the base such that the distance that each panel sits above the lowermost surface of the base is in the range of 20 mm to 80 mm, preferably 30 mm to 70 mm, more preferably 40 mm to 60 mm. In some embodiments, a distance of around 50 mm is preferred.
[0043] In some embodiments, two, three, four or more cladding panels are used to surround the housing. In some embodiments, four cladding panels are used to surround the housing, wherein each cladding panels surrounds about a quarter of the housing. In some embodiments, each cladding panel is configured to extend or span between two support elements. In some embodiments, the cladding panels may be configured such that sides of the cladding panels overlap, thereby to ensure that the cladding completely surrounds the housing.
[0044] In some embodiments, one or more of the cladding panels has a height which generally corresponds to the height of the housing / support elements. In some embodiments, one or more of the cladding panels has a predetermined height so as to cover a desired extent of the housing, thereby to facilitate in the provision of the dedicated compartments or zones. For example, the height of one or more of the cladding panels may be equal to a quarter, a third, a half or three-quarters of the height of the housing / support elements.
[0045] In some embodiments, one or more of the plurality of cladding panels is/are selectively removably attached to the respective support elements. In some embodiments, one or more of the plurality of cladding panels is hingedly attached to the respective support elements, thereby to be movable between a closed position to cover and inhibit access to the associated equipment modules and an open position to provide access to the associated
equipment modules. The selectively removable cladding panels and the hingedly mounted cladding panels advantageously provide access panels and access doors, respectively.
[0046] In some embodiments, a locking mechanism is associated with one or more of the removable cladding panels and/or the hingedly mounted cladding panels, the or each locking mechanism is configured to be selectively operable between a locked state in which the locking mechanism acts to hold the respective cladding panel in a closed position and an unlocked state in which the respective cladding panel can be moved away from the closed position (i.e. towards the open position). In some embodiments, each locking mechanism has an activation means or element for operating the locking mechanism.
[0047] In some embodiments, the activation means or element may be key-operated, require a dedicated tool to be operated and/or require a passcode to be entered to be operated. In some embodiments, the locking mechanism is key-operated. In some embodiments, the locking mechanism includes a latch, which is movable between a latching position in which the latch engages a portion of a support element for holding the respective panel against the respective support element, and an unlatched position in which the latch is free of the respective support element to enable movement of the panel away from its closed position.
[0048] In some embodiments, a different locking mechanism is provided for each access panel or door, whereby only authorised personnel or companies are provided with the activation means (e.g. key, tool, code, etc) for the respective locking mechanism, thereby to facilitate authorised access to the equipment modules housed behind that cladding panel.
[0049] In some embodiments, a cover is provided to cover the upper end of the support elements / housing. In some embodiments, the cover is in the form of a cover plate. In some embodiments, the cover plate has a skirt which depends downwardly from the cover plate. Preferably, the cover plate and skirt are integrally formed as a one-piece unit. In those embodiments in which the cover has a downwardly depending skirt, the cover plate and skirt cover the upper ends of the support elements and cladding panels, thereby to inhibit water ingress into the housing.
[0050] Preferably, the cover plate has a (central) hole to enable the cover to be positioned over, and be slidably received on, the spigot so as to rest on the top plate of the housing. In some embodiments, the hole in the central plate is sized such that the spigot is close fittingly
received therein. In some embodiments, the hole is shaped to complement the shape of the spigot; that is, the hole complements the outer profile of the spigot. In some embodiments, the hole is square or rectangular in shape. It will be appreciated that the use of a spigot with a square or rectangular profile together with a cover plate with a complementary square or rectangular hole advantageously ensures that rotational movement of the cover relative to the spigot is inhibited.
[0051] In some embodiments, the cover plate is circular, oval, triangular, square, rectangular or other suitable shape. In some embodiments, the cover plate has a cross- sectional area which is greater than that of the top plate of the housing. In some embodiments, the cover plate has a cross-sectional area which is substantially the same as that of the top plate of the housing.
[0052] In some embodiments, the housing is adapted to house two or more equipment modules. In some embodiments, the housing has a plurality of compartments or zones, each compartment or zone being configured to house one or more of the equipment modules.
[0053] In some embodiments, one or more of the equipment modules is/are mounted directly to the support elements. In some embodiments, one or more of the equipment modules is/are mounted to a single support element. In some embodiments, one or more of the equipment modules is/are mounted to or attached to two or more of the support elements.
[0054] In some embodiments, one or more of the equipment modules is/are mounted to the support elements via a mounting element such as, for example, a mounting bracket or bar. In some embodiments, each mounting bracket or bar is attached to the support elements. In some embodiments, one or more of the mounting elements is/are attached to a single support element. In some embodiments, one or more of the mounting elements is/are attached to, and extends between, two or more of the support elements.
[0055] In some embodiments, the equipment modules may include, but are not limited to, one or more for the following: power equipment, electrical equipment, electronic equipment, telecommunications equipment, radio frequency equipment, control, signal and processing equipment, surveillance equipment, wireless communications equipment, and antenna equipment.
[0056] By virtue of the open, spaced apart arrangement of the plurality of support elements
that form the housing, the equipment modules are advantageously housed in such a manner that they can be readily installed, accessed, serviced, repaired, replaced and/or tested. In addition and due to the housing extending from the base of the pole assembly, the access to the equipment modules can, in most instances, advantageously be achieved at or close to ground level. Furthermore, this arrangement enables the different equipment modules to be housed in distinct / dedicated compartments or zones, whereby separate access can be readily provided only to authorised persons or companies associated with the respective equipment modules.
[0057] According to another aspect of the present invention, there is provided a pole assembly, including: a base; a housing extending upwardly from the base, the housing having a first cross- sectional area and being configured for housing one or more equipment modules; and a mast extending upwardly from housing, the mast having a second cross-sectional area, wherein the second cross-sectional area is less than the first cross-sectional area of the housing.
[0058] According to another aspect of the present invention, there is provided a pole assembly, including: a mast having a base section and a top section; a first vent opening associated with the base section of the mast; a second vent opening associated with the top section of the mast; an open passageway extending from the base section to the top section; wherein, the first vent opening has an open area of a predetermined size, the open area of the first vent opening being substantially the same size as an open cross-sectional area of the passageway associated with the top section.
[0059] The formation of a first vent opening having substantially the same open area as that of the second open area advantageously induces an airflow through the passageway between the first vent opening and the second vent opening. For example, in applications where the air temperature outside the mast is greater than the air temperature within the passageway, the formation of a first vent opening having substantially the same open area as that of the second open area advantageously induces an airflow through the passageway from the first vent opening to the second vent opening. That is, in such applications, the first vent opening acts as an air intake opening through which air is drawn into the passageway of the mast, and the
second vent opening acts as an air exhaust opening through which air is discharged from the passageway. The movement of air through the internal passageway of the pole assembly is particularly advantageous in providing a cooling effect on equipment and equipment modules housed and operating within the pole assembly, particularly powered equipment and modules.
[0060] In some embodiments, the mast is a hollow tube or pipe. In some embodiments, the base section and top section are integrally formed such that the mast is a one-piece construction. In some embodiments, the mast is a modular construction. In some embodiments, the base section and top section are connected together to form the mast. In some embodiments, the circumference of the base is greater than that of the top section.
[0061] In some embodiments, the mast is formed from a relatively rigid material such as, for example, a metal. In certain embodiments, the mast (base section and top section) is formed of aluminium. It will be appreciated that the mast is not limited to being formed from metal, rather the mast could be formed of any suitably rigid material.
[0062] In some embodiments, the base section is formed as a hollow cylindrical or tubular section, wherein the passageway is defined by the internal open area of the cylindrical or tubular section. In some embodiments, the top section is formed as a hollow cylindrical or tubular section. In some embodiments, the base section has an internal open area and is formed as a hollow cylindrical or tubular section.
[0063] In some embodiments, the passageway defined by the mast has a constant cross- sectional open area. In some embodiments, the passageway defined by the mast has a cross- sectional open area which varies in size along the length of the mast. In some embodiments, the cross-sectional open area of the passageway associated with the base section of the mast is greater than the cross-sectional open area of the passageway associated with the top section of the mast. In some embodiments, the cross-sectional open area of the passageway defined by the mast may vary along the length of the mast. The cross-sectional open area of the passageway may vary continuously along the length of the mast. The cross-sectional open area of the passageway may change at discrete locations along the length of the mast.
[0064] In some embodiments, the first vent opening and second venting opening and passageway are configured to produce an airflow through the passageway with a flowrate in the range of 0.25 to 2.0 m/s, more preferably 0.25 to 1 .0 m/s. Preferably, the first and second vent openings and the passageway are configured to produce an airflow through the
passageway with a flowrate of about 0.5 m/s. A flowrate of 0.5 m/s has been found to be particularly advantageous for cooling equipment modules including, but not limited to, batteries, control units and other electrical systems housed within the mast.
[0065] In some embodiments, the first vent opening and the second vent opening are configured to be essentially parallel to one another. In some embodiments, the first vent opening and the second vent opening are configured to extend in planes which are orthogonal to one another. In some embodiments, the first vent opening and the second vent opening are configured to extend in the same plane to one another.
[0066] In some embodiments, the first vent opening is defined by an open (lower) end of the mast or base section. In certain embodiments, the first vent opening is formed in a side wall of the mast or base section. Preferably, the first vent opening is formed at or adjacent to one end (e.g. a lower end) of the sidewall of the mast or base section. In some embodiments, the first vent opening is a singular opening in the sidewall of the mast or base section. In some embodiments, the first vent opening includes a plurality of openings formed in the sidewall of the mast or base section, the plurality of openings being arranged in predetermined spaced apart relation relative to each other.
[0067] Preferably, the or each opening of the first vent opening is a hole, slit or slot having a circular, oval, square, rectangular or other suitable polygonal shaped profile. In some embodiments, one or more of the openings of the first vent opening extends in a direction generally parallel to the longitudinal axis of the mast (e.g. openings which extend in a vertical direction). In some embodiments, one or more of the openings of the first vent opening extends in a direction generally orthogonal to the longitudinal axis of the mast. (e.g. openings which extend in a horizontal direction). In some embodiments, one or more of the openings of the first vent opening may extend at an angle relative to the longitudinal axis of the mast.
[0068] In those embodiments in which the first vent opening includes a plurality of openings, each opening is configured and sized such that the sum of the open areas of the plurality of openings provides or equates to the total open area of the first vent opening (and thus also the open cross-sectional area of the passageway associated with the top section).
[0069] The plurality of openings of the first vent opening may be arranged in a regular or irregular array or pattern. In some embodiments, the plurality of openings of the first vent opening are arranged in a regular, uniformly spaced apart array about the periphery of the
mast or base section. In other forms, the plurality of openings of the first vent opening are formed as a group of openings arranged in a predetermined region of the mast or base section. In some embodiments, the group of openings are arranged on one or more sides of the mast or base section. In some embodiments, the group of openings may be arranged to cover or span a predetermined extent of the periphery of the mast or base section. For example, the group of openings may be arranged to span approximately 25%, 33%, 50%, 66%, 75% or 100% of the periphery of the mast or base.
[0070] In some embodiments, the second vent opening is defined by an open (upper or top) end of the top section. In certain embodiments, the second vent opening is formed in a side wall of the top section. Preferably, the second vent opening is formed at or adjacent to one end (e.g. an upper or top end) of the sidewall of the mast or top section. In some embodiments, the second vent opening is a singular opening in the sidewall of the top section. In some embodiments, the second vent opening includes a plurality of openings formed in the sidewall of the top section, the plurality of openings being arranged in predetermined spaced apart relation relative to each other.
[0071] Preferably, the or each opening of the second vent opening is a hole, slit or slot having a circular, oval, square, rectangular or other suitable polygonal shaped profile. In some embodiments, one or more of the openings of the second vent opening extends in a direction generally parallel to the longitudinal axis of the mast (e.g. openings which extend in a vertical direction). In some embodiments, one or more of the openings of the second vent opening extends in a direction generally orthogonal to the longitudinal axis of the mast. (e.g. openings which extend in a horizontal direction). In some embodiments, one or more of the openings of the second vent opening may extend at an angle relative to the longitudinal axis of the mast.
[0072] In those embodiments in which the second vent opening includes a plurality of openings, each opening is configured and sized such that the sum of the open areas of the plurality of openings provides or equates to the open cross-sectional area of the passageway associated with the top section (and thus also the total open area of the first vent opening).
[0073] The plurality of openings of the second vent opening may be arranged in a regular or irregular array or pattern. In some embodiments, the plurality of openings of the second vent opening are arranged in a regular, uniformly spaced apart array about the periphery of the mast or base section. In other forms, the plurality of openings of the second vent opening are formed as a group of openings arranged in a predetermined region of the mast or base
section. In some embodiments, the group of openings are arranged on one or more sides of the mast or base section. In some embodiments, the group of openings may be arranged to cover or span a predetermined extent of the periphery of the mast or base section. For example, the group of openings may be arranged to span approximately 25%, 33%, 50%, 66%, 75% or 100% of the periphery of the mast or base.
[0074] In some embodiments, the second vent opening is aligned with the first vent opening. For example, the first and second vent openings may be arranged on the same side of the mast or otherwise arranged to be positioned on the same vertical axis. In other embodiments, the second vent opening is arranged or positioned so as to be offset from the first vent opening. For example, the first vent opening and second vent opening may be offset by 90 or 180 degrees relative to each other about the longitudinal axis of the mast.
[0075] In some embodiments, the mast or top section of the mast includes one or more grooves or tracks, wherein the second vent opening is formed in one or more of the grooves or tracks.

[0078] Preferred embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings in which
[0079] Figures 1A-1C show an embodiment of pole assembly having a housing section for housing equipment modules, with a mast or pole extending from the housing section;
[0080] Figure 2 is an exploded view of the housing section of the pole assembly of Figure 1 ;
[0081] Figure 3 shows another embodiment of a pole assembly in which the housing section has selectively removable access panels to facilitate access to the equipment modules housed within the housing; and
[0082] Figure 4 shows another embodiment of a pole assembly in which the housing section has a lower housing section and an upper housing section stacked on the lower housing section.
Preferred embodiments of the invention
[0083] The present invention will now be described with reference to the following examples which should be considered in all respects as illustrative and non-restrictive. In the figures, corresponding features within the same embodiment or common to different embodiments have been given the same reference numerals.
[0084] Referring to Figure 1 , there is illustrated a pole assembly 1 . The pole assembly 1 is erected on a concrete foundation 2 and includes a base 3 and a housing 4.
[0085] In the illustrated embodiment, the base 3 is formed of a metal and is cylindrical in shape. The base 3 is configured to be secured to the foundation 2 by four mechanical fastening elements in the form of lengths of thread bar 5. Each threaded bar 5 extends in a generally vertical direction. The upper end of each threaded bar 5 projects through a respective through hole 6 formed in the base 3.
[0086] The base 3 includes a flange 7 mountable on or adjacent to the upper face of the base. The flange 7 has an operatively upper surface which, in use, defines a mounting surface 8 from which the housing 4 extends. The flange 7 includes four openings which are configured to receive a respective one of the threaded bars 5. The openings in the flange 7 are arranged to complement or otherwise correspond with the arrangement of the holes 6 in the base 3 such that each opening in the flange 7 can be aligned with a respective hole 6 in the base 3.
[0087] The aligned holes define a passageway through which a respective one of the threaded bars 5 can pass. One or more locking elements in the form of internally threaded nuts are used to secure the upper end of the threaded bar 5 to the flange 7. In the illustrated
embodiment, two locking nuts are threadedly engaged to an upper portion of the associated threaded bar protruding above the flange, and one locking nut is threadedly engaged to the upper end of that threaded bar below the flange, whereby the nuts above and below the flange can engage the respective sides of the flange to secure the threaded bar to the flange / base.
[0088] The manner in which the base 3 is secured to the foundation with the threaded bars 5 inhibits rotational movement of the base 3 and/or upward movement of the base 3 away from the foundation 2.
[0089] The housing 4 is formed by a plurality of elongate, structural support elements 9, which extend upwardly in a generally vertical direction from the base 3. In the illustrated embodiment, the housing 4 includes four support elements 9 which are equally spaced apart from each other.
[0090] The support elements 9 are arranged to form the housing 4 such that one or more (preferably a plurality of) equipment modules can be housed therebetween. Each support element 9 is preferably an elongate, structural element of the pole assembly 1 . In this way, the housing 4 can form a support structure for supporting a mast 11. In the illustrated embodiment, each support element 9 is formed from a round steel tube with a diameter of about 60 mm. Each of the support elements 9 extends in a direction parallel to the others.
[0091] A lower end of each support element 9 is mounted on the upper surface 8 of the flange 7 of the base 3. An upper end of each support element 9 is connected to an underside of a circular plate 12, thereby to hold the upper ends of the support elements 9 in relative spaced apart relationship. In the illustrated embodiment, a cross-sectional profile of the plate is substantially the same as the cross-sectional profile of the base 3 / flange 7. Preferably, the plate 12 has a central opening to allow air to pass therethrough.
[0092] In the illustrated embodiment, the support elements are evenly spaced apart and positioned intermediate a pair of the openings formed in the base 3 / flange 7.
[0093] In the illustrated embodiment, the housing 4 includes four support elements 9 which are arranged in a generally square formation. The support elements 9 define a boundary of an open volume or space of the housing 4 in which the one or more equipment modules 10 can be housed. The flange 7 and the plate 12 form the upper and lower limits of the housing 4, with the support elements 9 defining the sides of the housing 4.
[0094] The support elements 9 are arranged and sized to provide a desired size to the open volume or space formed between the support elements. For example, the cross-sectional area of the base 3 / flange 7 may be a predetermined size or diameter, thereby to enable the housing to accommodate one or equipment modules therebetween. Similarly, each support element 9 preferably has a predetermined length such that the housing has a desired height, thereby to provide a sufficient open volume or space for housing the equipment modules 10.
[0095] Referring to Figure 4, an embodiment of a pole assembly 1 having a housing 4 with two sections (a lower section and an upper section) is shown. Each section is adapted to house one or more equipment modules 10. The two sections are arranged in a vertical stack, with one section on top of the other. The lower section is seated on the base 3. In the illustrated embodiment, the cross-sectional area of the lower housing section is greater than that of the upper housing section.
[0096] As foreshadowed, the pole assembly 1 includes an elongate mast 11 which is supported by and extends upwardly from the housing 4. More specially, the mast (or pole) 11 extends upwardly from the top plate 12 of the housing 4. The mast is preferably formed of a substantially rigid material such as, for example, steel or aluminium.
[0097] As shown in Figures 1 B and 1C, a mounting formation in the form of a spigot 13 is arranged on the top plate 12 of the housing 4. The spigot 13 facilitates secure and stable mounting of the mast 11 . In the illustrated embodiment, the spigot 13 is integrally formed with the top plate 12 as a one-piece unit. The spigot 13 extends upwardly from the top plate 12, whereby the spigot 13 can be received in a lower end of the mast 11 to support the mast in a generally upright (e.g. vertical) orientation.
[0098] The mast 11 is preferably of a hollow construction with an open lower end, thereby to facilitate mounting of the mast over the spigot. The spigot has a length (or height) such that, in use, it extends a predetermined extent with the lower end of the mast, thereby to facilitate secure and stable mounting of the mast.
[0099] In the illustrated embodiment, the spigot is formed of a length of pipe or tube such as, for example, a rolled hollow section (RFIS). This provides the spigot with a substantially square cross-sectional profile, thereby to inhibit relative rotational movement between the mast and the spigot, in use. To further reduce relative rotational movement between the mast and the spigot, a plurality of threaded fasteners extend through holes formed in the lower end of
the mast and threadingly engage threaded holes formed in the walls of the spigot.
[00100] In some embodiments, the mast is configured to enable mounting of one or more accessories or components thereto. For example, accessories or components such as, for example, lights, flags, banners, audio speakers, wires and the like may be directly or indirectly attached to the mast. In some embodiments, the accessories or components may be attached to the mast via a connecting element such as, for example, a bracket, mounting arm and the like.
[00101] As shown in the illustrated embodiments, the mast has a cross-sectional area which is less than the cross-sectional area of the housing.
[00102] The mast 11 preferably has at least one mast vent opening 15, and the housing 4 preferably has at least one housing vent opening 14. The mast and housing vent openings, together with the hollow interior of the housing, spigot and mast, form an open passageway to facilitate airflow through the pole assembly 1 . The airflow is preferably created as air is drawn in through the housing vent opening 14 and exhausted through the mast vent opening 15. The mast vent opening 15 may include a plurality of openings (e.g. holes, slits). The housing vent 14 opening is formed by the open end of the housing, i.e. towards the lower end of the pole assembly 1 .
[00103] With reference to Figure 2, the housing vent opening 14 may be provided by mounting cladding panels 16 radially outwardly from the periphery of the base 3 by a distance of approximately 30 mm, and such that the lower ends of the cladding panels 16 sit above the foundation 2 and the lowermost surface of the base 3 by a distance of around 50 mm. This arrangement creates a generally ring-shaped opening between the base 3 and the cladding panels 16, whereby air can flow into the interior of the housing 4 / pole assembly 1.
[00104] It will be appreciated that this airflow advantageously assists to control (e.g. cool) the temperature inside the housing and mast, and thus the equipment modules. For example, the airflow can be used to vent or exhaust warm or hot air, created from heat generated by the equipment modules, out of the mast via the mast vent opening 15. In addition, the air flowing internally through the housing 4 can pass over the equipment modules 10, further assisting to control the temperature (e.g. cool these modules).
[00105] Cladding 16 is provided to enclose the housing 4. The cladding 16 is preferably
attached to one or more of the support elements 9. In the illustrated embodiments, the cladding 16 includes a plurality of cladding panels. Each cladding panel 16 is configured to complement the shape of the base 3. In the illustrated embodiments, each cladding panel 16 is curved or arcuate in shape. One or more of the cladding panels 16 is secured to one or more of the support elements 9 by one or more fastening elements such as, for example, screws which pass through holes in the cladding panels and threadingly engage the respective support element.
[00106] In Figures 1 and 2, four cladding panels 16 are used to surround the housing 4, wherein each cladding panel surrounds about a quarter of the housing. Each cladding panel 16 is configured to extend or span between two support elements 9. The cladding panels 16 may be configured such that respective sides of adjacent cladding panels overlap, thereby to ensure that the cladding completely surrounds the housing 4.
[00107] In Figures 1 and 2, each cladding panel 16 has a height which generally corresponds to the height of the housing 4 / support elements 9. In Figure 3, each cladding panel 16 has a predetermined height so as to cover about a third of the height of the housing, thereby to facilitate in the provision of the dedicated compartments or zones.
[00108] One or more of the plurality of cladding panels 16 is/are removably attached to the respective support elements, thereby to provide an access panel. One or more of the plurality of cladding panels 16 may be hingedly attached to the respective support elements 9, thereby to provide an access door which is movable between a closed position to cover and inhibit access to the associated equipment modules and an open position to provide access to the associated equipment modules.
[00109] A locking mechanism is preferably associated with one or more of the access panels and doors. Each locking mechanism is configured to be selectively operable between a locked state in which the locking mechanism acts to hold the respective cladding panel in a closed position and an unlocked state in which the respective cladding panel can be moved away from the closed position (i.e. towards the open position).
[00110] Each locking mechanism has an activation means or element for operating the locking mechanism. The activation means or element may be key-operated, require a dedicated tool to be operated and/or require a passcode to be entered to be operated. The locking mechanism may include a latch, which is movable between a latching position in which
the latch engages a portion of a support element for holding the respective panel against the respective support element, and an unlatched position in which the latch is free of the respective support element to enable movement of the panel away from its closed position.
[00111] A different locking mechanism may be provided for each access panel or door, whereby only authorised personnel or companies are provided with the activation means (e.g. key, tool, code, etc) for the respective locking mechanism, thereby to facilitate authorised access to the equipment modules housed behind that cladding panel.
[00112] In the illustrated embodiments, a cover 17 is provided to cover the upper end of the support elements 9 / housing 4. The cover 17 is in the form of a circular cover plate with a skirt which depends downwardly from the cover plate. The cover plate and skirt are integrally formed as a one-piece unit. In use, the cover plate and skirt cover the upper ends of the support elements and cladding panels, thereby to inhibit water ingress into the housing 4.
[00113] Preferably, the cover 17 has a central hole to enable the cover to be positioned over, and be slidably received on, the spigot 13 so as to rest on the top plate 12 of the housing 4. The hole in the cover plate is preferably sized such that the spigot 13 is close fittingly received therein. The hole is preferably shaped to complement the shape of the spigot. In the illustrated embodiment, the hole is square in shape. It will be appreciated that the use of a spigot with a square or rectangular profile together with a cover plate with a complementary square or rectangular hole advantageously ensures that rotational movement of the cover relative to the spigot is inhibited.
[00114] The housing 4 is adapted to house two or more equipment modules 10. The housing 4 may be configured to have a plurality of compartments or zones, each compartment or zone being configured to house one or more of the equipment modules. The compartments or zones may be defined by the configuration and/or positioning of the cladding panels 16.
[00115] As most clearly shown in Figure 2, the equipment modules are mounted to the support elements 9 via a mounting element such as, for example, a mounting bracket or bar 18. Each mounting bracket or bar 18 is fixedly attached to the support elements 9, and preferably extends between at least two support elements. Preferably, each mounting bracket or bar 18 is attached in a substantially horizontal orientation. For clarity, only one equipment module 10 is illustrated in Figures 1 and 2. However, as previously described, a plurality of equipment modules 10 can be readily mounted within the housing 4.
[00116] The equipment modules 10 may include, but are not limited to, one or more of the following: power equipment, electrical equipment, electronic equipment, telecommunications equipment, radio frequency equipment, control, signal and processing equipment, surveillance equipment, wireless communications equipment, and antenna equipment.
[00117] By virtue of the open, spaced apart arrangement of the plurality of support elements 9 that form the housing 4, the equipment modules 10 are advantageously housed in such a manner that they can be readily installed, accessed, serviced, repaired, replaced and/or tested. In addition and due to the housing 4 extending from the base 3 of the pole assembly 1 , the access to the equipment modules 10 can, in most instances, advantageously be achieved at or close to ground level. Furthermore, this arrangement enables the different equipment modules to be housed in distinct / dedicated compartments or zones, whereby separate access can be readily provided only to authorised personnel or companies associated with the respective equipment modules 10.
[00118] In these and other respects, the invention represents a practical and commercially significant improvement over the prior art. Although the invention has been described with reference to specific examples, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms. It should also be understood that the various aspects and embodiments of the invention as described can be implemented either independently, or in conjunction with all viable permutations and combinations of other aspects and embodiments. All such permutations and combinations should be regarded as having been herein disclosed.
