Abstract: A service unit (65) comprising a frangible mounting means (63) and a hollow body adapted to be mounted on a supporting surface by the mounting means. Mounted within the hollow body are power distribution means (61, 71, 72, 74, 76, 77) and power metering means (75), and at least one lighting means (78). The hollow body is provided with a plurality of apertures with releasably securable covers (86). Water (62, 66, 67), telephone (61a, 71a, 72a, 76a) and other service equipment can also be mounted within or attached to the body to provide the desired service capabilities.

Description: "MULTIPLE SERVICE UNIT" This invention relates to a multi-functional service unit for trailer parks, camping areas, marinas, jetties, wharves and like installations as well as building sites. In such trailer parks, marinas, building sites and the like, essential services comprising water, electrical power and lighting are frequently provided as separate systems. The resultant combination of hoses, pipes, cable and supports is inconvenient in use, expensive to install and maintain and is usually unsightly in appearance. In order to alleviate such problems, it has previously been proposed to provide a service unit 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 required. In one type of prior art service unit, a power outlet box, a meter box, a water pipe and appropriate connecting conduits 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 units 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 acceptable structure. A further difficulty 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 unit. This makes it very difficult 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 if the fuse blows, the whole area is blacked out until the faulty circuit or fuse is repaired. A number of further 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, power distribution outlets and lights which 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 accidentally 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 \ v. severed thus creating a grossly unsafe condition. The present invention has been conceived with the aim of alleviating the abovementioned 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 maintain¬ able unit suitable to any location requiring a service unit of this type. A particular advantage of service units according to the invention is that access to power distribution outlets and other services may be strictly controlled by the provision of lockable covers. The covers serve a dual function in that not only do they prevent unauthorized consumption of services provided, but the covers may also be adapted to prevent accidental or deliberate disconnection or removal of service connections such as power leads, telephone cables etc. To this end the lockable covers may be provided with apertures, preferably on the lower peripheral edge, the apertures being dimensioned such as to permit the cover to be locked while the service leads, cords, cables etc. are connected to the service unit. Additionally, the inner face of the lockable covers may be adapted to engage the plugs of the service connections such that when the cover is locked it is not possible to remove the plug from its corresponding socket by applying tension to the service lead, cord, cable etc. According to the invention there is provided a service unit comprising: a hollow body adapted to be mountable on a surface by said mounting means; power distribution means; and; power metering means, said hollow body being provided with a plurality of apertures with releasably securable covers. Preferably the releasably securable covers are adapted to prevent, in use, removal or disconnection of a service connection. ^ Preferably the service unit comprises frangible mounting means. Preferably the frangiblemounting means comprises an essentially hollow, walled mounting base with inwardly extending mounting lugs adjacent its upper edges. Some of the lugs may be adapted for connection to corresponding mounting lugs or a mounting plate formed in the base portion of the body and additional lugs are provided for mounting the service unit to a base. Certain of the lugs are adapted by dimension, to preferentially fracture in the event of impact. The frangible base may also be provided with a plurality of apertures to permit ingress of ventilating air or egress of water in the event of flooding. Alternatively, the frangible mounting means may comprise frangible mounting bolts or the like. Such bolts may be formed from relatively low tensile materials, for example nylon, aluminum, brass or like materials. Preferably, the service unit is provided with a plurality of power metering means and power distribution outlets to provide independent service to a plurality of users. Each power distribution outlet may be connected to a separate circuit comprising a power consumption meter, a circuit breaker and an indicator means to indicate a tripped circuit breaker. Preferably the lighting means comprises an incandescent or fluorescent light mounted adjacent the upper part of the body. Depending on the location of the service unit, i.e. at a campsite, trailer park, marina, wharf, jetty or the like, the lighting means may be provided with a suitable diffuser means or reflector means. Preferably the lighting means is provided in the top or cap portion of the service unit and is adapted to provide downwardly directed diffuse light about- all or a portion of the service unit. The lighting- means may also be adapted to provide interior lighting for the service unit. Additionally or alternatively, the lighting means may comprise an exterior light mounted atop the service unit. - &n OTtr O PI /*, ■ ■ WIPO . - 5 - Site identification means such as an illuminated number or other indiciae may also be incorporated in the exterior light diffuser as well as appropriately coloured segments for night-time marine navigation purposes if applicable. The lighting means may additionally or alternatively comprise a "foot-light" mounted adjacent the lower part of the body and may be downwardly directed by, for example, mounting the light behind a louvred cover plate. The lighting means of the service unit is preferably connect¬ ed in a circuit with a circuit breaker and an indicator to indicate a tripped circuit breaker. In an alternative embodiment of the invention, the lighting means may be actuable by a light-sensitive switching means. In a most preferred arrangement, the lighting means is mounted within the top or cap portion of the service unit, the top or cap portion being adapted to extend beyond the walls of the unit to form an outwardly extending rim. The rim may act as a protective cover for the lighting means and permit the light to be directed downwardly as required. Apertures are arranged in the body to permit ease of installation of the various service components and also to permit ease of access for maintenance purposes. The aperture covers may be releasably secured to the body by any suitable means such as screws, bolts or the like and are preferably of the type which discourage unauthorized tamper¬ ing or removal. Preferably, the service components are mounted on a frame which may be withdrawn from the top of the service unit to permit replacement or maintenance of the service components. s - The body of the service unit may be constructed from any suitable material, preferably of a non-corrosive and generally maintenance free material such as aluminum, plastics etc .
