Description
78~;
THIS INVENTION relates to a mul-ti-func-tional service unit for trailer parks, camping areas, marinas, jetties, wharves and like installa-tions as we].l as building sites.
In such -trailer parks, marlnas, building sites and -the like, essen-tial services comprising water, electrical power and lighting are fre~uently provided as separate systems. The resultant combination of hoses, pipes, cable and suppor-ts is inconvenient in use, expensive to ins-tall and main-tain and is usually unsightly in appearance. In oraer to alleviate such problems, it has previously been proposed to provide a service uni-t comprising a number of electrical power outlets and a power consumption meter in a single box or separate boxes on a support pole. Electrical wiring may be provided to the boxes via a conduit attached to the exterior of the pole or via the hollow space within a tubular pole. A water pipe with tap affixed may also be attached to the exterior of the support pole if re~uired In one type of prior art service unit, a power outlet box, a meter box, a water pipe and appropriate connecting condui-ts are integrally cast within a shaped concrete structure.
Of the prior art service units previously available most have been designed to suit a particular location in a campsite, trailer park, building site etc. and to provide a very limited number of services. Such service un.its are usually expensive to install and extremely difficult to ~ maintain. Apart from the possibility of mounting additional : boxes to the post-mounted service unit, none of the prior art units has contemplated a device which combines the features of ease of installation, ease of maintenance and the flexibility to accommodate a wide range of service functions within a simple, inexpensive and aesthetically accep-table struc-ture.
A further difriculty associated with the prior art service unit installations is that normally only three power outlets are permitted on one power circuit, with the fuses located at a main switchboard centre remote from the service 785;
unit. This makes it very di~Ficu]t to locate -the correct fuse for a faulty power outlet. In addition, it is difficult to provide effective safety circuits for such outlets e.g. if the electrical insulation is damaged or water enters the outlet. Similarly, all the lights for a campsite, trailer park, marina, building site or the like normally share a common fuse, so that in the case of a single power circuit fault, or iE the fuse blows, -the whole area is blacked ou-t un-til the faulty circui-t or fuse is repaired.
A number of fur-ther difficulties appear -to have been inherent in prior art service units in that they are prone to damage by vandals or by impact from vehicles or marine vessels. Many of the prior art devices have exposed power meters, switches, distribu-tion outlets and lightswhich may be easily damaged by vandals and many have exposed mounting bolts, screws and the like which permit unauthorized tampering. A particular disadvantage associated with prior art units is the manner in which they are mounted to a ground surface, jetty, marina pontoon or the like. Most devices are rigidly mounted to a base by bolting or by casting in a concrete base. In the event that a vehicle or marine vessel accldentally contacts such a rigidly mounted service unit, the unit itself may be severely damaged or if mounted on a jetty or marina pontoon, the jetty or pontoon may suffer damage of a most expensive nature. As in most prior art units, the power and water conduits are rigidly mounted to the service unit, impact damage by a vessel or vehicle may cause the power and water supply conduits to be severed thus creating a grossly unsafe condition.
Another most important weakness of the prior art service unit lies in the fact that access to the meter power can readily be had by unauthorized users.
Now, uncontrolled use of power by unauthorized consumers .,~
~LB~
in a caravan park~ mari~a or the like~ can add substantially to the o~erhead cost of running such an operation~ It is thexe~ore a ~ery important feature of the present invention to pro~ide metered power for authorized consumers only, whereby to enable a strict control of operating cost The present invention thus offers this essential feature by providing lockable access doors which prevent unauthorized users of power from using power at the expense of another caravan park of marine user.
The present invention has been conceived with the aim of alleviating the above mentioned problems and to provide a simple, inexpensive and aesthetically acceptable service unit, capable of providing a wide range of services and at the same time providing an easily maintainable unit suitable to any locati~n requiring a service unit.
