Description:
FIELD OF THE INVENTION 
     The present invention relates to a system of cabling and conduits along with means to provide ease of access to the cabling, in particular but not exclusively to cabling used by service providers to provide services to buildings or structures (both temporary or permanent) such as domestic properties, offices, stadia, wharves, concerts and the like. 
     BACKGROUND ART KNOWN TO THE APPLICANT 
     The placement of various types of cables and conduits (hereinafter called “conduits”) for example those of service providers, such as phone, gas, water and power, is traditionally effected by each service provider independently digging at different, and sometimes the same, locations on a property site so that each service provider may place their independent service conduits. 
     It is usually difficult to schedule all service providers to place their conduits at a property site on the same day, or over a relatively short period, and as conduits cannot be left exposed and unattended on a property site, the effect of this is that areas of a property site are repeatedly dug by each successive service provider when laying their respective conduits. 
     Due to the time and effort expended by each service provider in independently digging and laying their conduits at a respective site, the customer experiences delays in receiving provider services and added expense due to the cumulative work required to be performed by each provider in preparing the site for the laying of their conduits. 
     Furthermore, access points to the various conduits for the purposes of ‘servicing’ or indeed to ‘cut someone off’ for (for example) non payment of the service provider&#39;s invoice also tend to be scattered around the structure that is being provided with the service. 
     OBJECT OF THE INVENTION 
     It is an object of the present invention to provide a system for ease of placement of service provider&#39;s conduits at a property site, together with the provision of one or more access points for the conduits and or at least to provide the public with a useful choice. It is intended that the description and drawings of NZ 536486 are imported into this specification. 
     STATEMENT OF THE INVENTION 
     Accordingly the invention consists in a system for placement of conduits to a property site comprising a conduit receiving channel member shaped to receive a selected plurality of conduits, and one or more access points adapted to enable access to a portion of the conduit receiving channel member. 
     Such an arrangement enables easy detection of service pipes to and from a property site. 
     This is because although using detection equipment it is normally easy to locate underground gas, electric and telephone pipes/cables running to and from a property or structure, water pipes are notoriously difficult to detect and are usually found once a digger has destroyed them by accident. If all of the pipes/cables were located together, then this problem would not occur. 
     Furthermore, if more than one access point is used, then, in respect of a gas pipe where the mains pressure is far higher than the pressure used in a property or structure a conventional regulator incorporating a gas meter (wherever it is installed within the property or structure) to ‘step down’ the pressure to a more usable level need not be used. Instead, a regulator unit and a meter reading unit which individually can be much smaller, may be used if one is fitted at one access point and the other is fitted at another access point. 
     Water pipes on the other hand, do not tend to require any such regulator however, should a back flow regulator or limiting valve/filter be required the system will allow for its provision. In addition although electrical cabling may require a regulator in the form of an electrical booster to ‘step up’ the supply (if for example the property or structure is to be provided with or capable of using multiple television sets). As such, the booster can be located at the or each access point. 
     With the advent of modem technology, satellite dishes for TV reception for example, could in the not too distant future be reduced in size to the point where they too could be fitted to an access point. 
     Therefore, preferably the system is provided with one or more ‘mains to property or structure’ regulators accessible via at least one access point. 
     Such an arrangement has the advantage that not only could all regulators be accessed from the same point, but in the example of a gas pipe given above the size of the unit can be reduced as the meter and the regulator can now be separate items, one located at an access point of the system and the other located in the property or structure. 
     Preferably, there are two access points. If one of the access points houses each of the meters e.g. gas, water, electric together with taps to turn each of them off then, new occupants to the property or dwelling will know immediately where to go to turn off or read the necessary appliance/meter. 
     In addition, with more than one access point conventional back flow prevention measures can be installed at the or each access point. The larger number of access points also enables a greater number of devices to be fitted in series (at the access points) that are associated with each service. For example, one access point could incorporate a replaceable water filtration device and another access point would enable a water sterilisation device (e.g. UV light based) to be fitted effectively in series with the water filtration device. 
     More preferably, at least one access point is remote from the structure. This has the advantage that servicing work of the system, for example, can be carried out without the need to step onto the property of an owner being supplied with the services. 
     Furthermore, (again using the gas supply as an example) if the gas supply can be turned off from an access point at ground level remote from the structure (instead of adjacent to it), then, in the event of a natural catastrophe such as forest fire, there is little to no chance of a gas shut off tap melting or being damaged to the point where the gas is free to escape causing a “flame thrower” effect to take place (as has been the case in Australia on occasion during such fires, thus destroying the properties in question). 
     Solenoids employed for gas shut down the line could thus be fitted at access points remote from the structure and if pulse meters were installed, services could also be read remote from the structure. 
     More preferably still, at least one access point is located on or adjacent the exterior of the structure. 
     Preferably one of the access points is located at or below ground level. 
     Preferably, the or each access point is sufficiently protected against ingress from the elements and living organisms. Water and creatures from the class known as insecta can flow in either direction if there is a leak or existing pipe work for them to travel along respectively. In terms of the latter, means could be provided to prevent living organism movement along or through the system. 
     Such means will be known to the person skilled in the art and as a result need not be discussed further in this specification. 
     Preferably the or each access point is in the form of a box. 
     The box could be formed from metal, metal alloys, plastics material or any appropriate selection or combination of the above materials. 
     The invention includes within its scope a system substantially as herein described with reference to and/or as illustrated in any appropriate selection or combination of the accompanying drawings. 
     The invention further includes within its scope a structure fitted with or otherwise connected to such a system.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     A receiving system for conduits is provided which in the first preferred form comprise an elongated plate  1 . The plate  1  shown in  FIG. 1  is shortened for the purposes of clarity. The plate  1  is provided with a plurality, such as six, elongated depressions  2  thereacross. The plate  1  is desirably moulded as a single unit from a suitable plastics material such as polyvinyl chloride. 
     The ridge  3  between the channels  2  may carry either a bulbous rib  4  or a narrow mouthed channel  5  into which the rib  4  is a snap fit. The central ridge  3  in the embodiment in  FIG. 1  carries neither. 
     Side flat areas  6  again may each carry either a co-operating rib  7  or a channel  8  which are a snap fit together. In the embodiment of  FIG. 1  a “Christmas tree” shaped rib and channel are shown. Plates  1  can then be snapped together as seen in  FIG. 2  to form channels  10  between the two plates  1 . Intermediate ribs are connected together, save for the centre ribs  3 . The “Christmas tree” construction provides additional connection between the side ridges. 
     The dimensions of the channels  2  formed by co-operation of male  4 ,  7  and female  5 ,  6  attachment members are determined by the diameter of conduits  12  which are to be positioned in use in the channels  2 . 
     A connection member  20  is preferably provided for the system so that plates  1  placed end to end may be connected. The connection member may comprise two substantially parallel stringers  21  connected by cross members  22 . 
     The connection member  20  is provided with securing means preferably in form of apertures  25  through which bolts (not shown) or the like may pass allowing the connection member  6  to engage with the plate  1 . To enable this, the plates I may have corresponding apertures  27  at, for example, the edges and centre thereof. The connection member therefore holds two receiving plates  1  together end to end. 
     If desired a connection plate  30  can span two receiving system plate pairs. This enables a good connection between the plate pairs to be made. In  FIG. 4  a horizontal turn connector  33  is provided. Vertical turn connectors and connection of other radii can also be provided. In use a service provider&#39;s conduit  12  may be feed through a channel  10  in the plates  1 , as shown in  FIG. 2 . 
     The combination of the integers results thus far in a system for placement of conduits comprising a receiving means, optional attachment means, and clamping means as illustrated in  FIG. 3 . 
     Referring now to  FIG. 5  conduits  40  are provided which may be extruded from, for example, a suitable plastics material. The construction of  FIG. 5  shows two conduits  40  therein. Thus in this embodiment the conduits  40  are extruded in pairs. It will be apparent of course that a set of conduits  40  could be extruded to provide a single conduit or a number of conduits greater than two up to a suitable practical limit such as, for example, six conduits. However, pairs of conduits  40  are the preferred form. 
     The pair of conduits  40  are linked by bridging parts  31  and connection means are provided to allow the pairs of conduits  40  to be connected in a side by side relationship. In the preferred form the connection means are provided by a pair of spaced apart outwardly extending flanges  43  to form a channel  44 . The mouth of the channel is narrowed by inwardly extending ribs  34  which are desirably shaped to provide a snap fit as will be described further hereinafter. 
     A protrusion  35  is provided opposite the ribs  32  and in the embodiment describe the protrusion is hollow having an interior  36 . The width of the protrusion  35  is such that the protrusion is able to be a snug fit into the space  33  of an adjacent set of conduits  40  as can be seen from  FIG. 6 . 
     In the preferred form towards the base of the protrusion  35  are provided inwardly extending longitudinal channels  37  into which a rib  34  may pass. 
     The plastics or other material from which the conduit pairs are formed are preferably such that there is sufficient flexibility in the material to enable the arrangement to be performed and also, by reference to  FIG. 7 , an elongated strip of material is shown which is sufficiently flexible to be able to be formed into curves such as that shown at  41 . 
     As an alternative shape members may be provided which are able to be connected to the part  40 . 
     As can be seen at end  42  of the member  40  the conduit pairs may be left unconnected or may be separated, for example, by cutting along bridges  31  so the ends of the conduits  40  may be manipulated into any suitable position. Thus the conduits have substantially parallel longitudinal axes over at least a substantial part of the length of the conduits. 
     By providing a further part engagement means sets of conduits could be built into blocks of conduits if desired. 
       FIGS. 8 to 10  show a kerb side services box that is generally referenced  80 . Fitted at ground level the hermetically sealable box  80  is connected directly to a number of services such as mains supply gas, phone, electricity etc. It is also provided with a plurality of quick connect points to enable complimentary ends of the conduits  81  (as already described) on the “house” side of the box  80  to be connected up to the mains supply (or national or telephone grid) via box  80 . Services in conduits  82  can be from the “grid” side connected to box  80 . Box  80  contains suitable connection conduits  83 . 
     The remote location of the box  80  relative to the property  84  means that access to the box  80  by a service repair man is possible without walking onto the property  84  or the land associated with it. Box  80  may also contain a regulator for the gas mains to enable the mains pressure to be stepped down. 
       FIG. 10  shows another box  90 , (a house end service box) again fitted with a number of quick connect points at  91  which respective complimentary ends of the conduits  81  can connect to. Box  90  may also contain the meter for the gas and the electricity and the water enabling all of these to be read by an individual or meter reader without the need for access into the interior of property  84  as the box  90  is located on the exterior wall of the property  84 . 
     Referring now to  FIGS. 11 to 14  the kerb or road side box  80  in this construction is placed below footpath  100 . The footpath  100  has a suitable removable cover  101  to allow access to the interior  102  of the box  80 . 
     Adjacent the footpath  100  is a kerb  104  and below the kerb  104  is provided an elongated channel member  105 . The channel member  105  is divided into a number of conduits to receive services such as water, power, telephone, gas and the like. The embodiment shown shows six such conduits  106 . 
     Below the conduits  106  may be a drain  107 . The box  80  may be shaped by providing upper and lower tongues  108 ,  109  which can clip onto ribs  110 ,  111  on the channel member  105 . 
     The box  80  may have a pin  115  extending outwardly (preferably downwardly) from the box  80  to provide levelling and support. 
     The box  80  may have a number of substantially horizontal divider panels  118  to support devices such as connector and/or metering boxes  119 . 
     Thus service are taken from the conduit  106  in which it has, through the wall of the channel  105  and box  80  to a connector within box  80  and then to the appropriate services conduit  81 . 
     The construction described is constructed beside a roadway  120 . 
     The system could also incorporate pulsed meters enabling meter readings to be obtained not only remote from the property or structure but off site and read electronically. Conventional pulsed meters are usually used to read one service e.g. electricity, but the proximity of the pipes/cabling of the system, could, in principle enable a pulsed meter to be developed which could read all three either simultaneously or consecutively at for example the ‘flick of a switch’. 
     Special keys can be required to gain access to both boxes  80  and  90 , the key for box  90  could probably be purchased by the property owner but the key to access box  80  would only be available to workers employed by the service providers. 
     The boxes and the conduits could have free areas or unallocated connections to allow for future proofing in the event of further services becoming available. 
     Throughout the description and claims of this specification the word “comprise” and variations of that word, such as “comprises” and “comprising”, are not intended to exclude other additives, components, integers or steps.
