DESCRIPTION:

BRIEF SUMMARY
This invention relates to a service line terminal box system especially for ships moored to quays but also for aircraft in airports, caravans on camping sites and the like.
When ships, pleasure boats and particularly fishing boats lie berthed in harbour they need to have the use of electrical power from the public mains. To satisfy this requirement, mostly rather provisional arrangements have been provided hitherto, comprising distribution boxes from which overhead lines are temporarily drawn to the different boats. These prior-art arrangements suffer from obvious drawbacks with regard to security. The same conditions prevail on camping sites and in airports as well.
The primary object of the present invention therefore is to provide an outdoor terminal box system which ensures improved security and particularly serves to supply fishing boats moored to quays with electrical power. However, the terminal box is also more generally useful, for example, for the supply of water and/or fuel.
To this end, the invention provides a service line terminal box system supplying, at predetermined points outdoors, such facilities as electrical power, telephone service, water, compressed air, vacuum and/or fuel particularly for ships moored to quays. This terminal box system comprises a plurality of service line terminal boxes, a coverplate countersunk in the ground at the predetermined points for each of the boxes, over which coverplate vehicles can be driven and which is self-locking and in closed position leaves an opening to the interior of the box to permit passing therethrough a line temporarily connectible to a service line socket outlet in the box, the bottom of each of the boxes being inclined towards a drain hole connected to a drain pipe, and one or more service lines fixedly connected through holes in the walls of the box to the service line socket outlet in the box.
The invention will be described in greater detail below with reference to the accompanying drawing which illustrates an embodiment of the service line terminal box system for supplying ships with electrical power.
In the drawing:
FIG. 1 is a top plan view of a harbour quay structure; and
FIG. 2 is a cross-section on the line II--II in FIG. 1.
In the harbour shown in FIG. 1, a plurality of service line terminal boxes 1 are countersunk in the quay short of the edge thereof. Each of the boxes contains three one-phase electrical socket outlets 2 (see FIG. 2) which are energized via underground cables 3 from distribution boxes 4 which in turn are connected to the public mains. Each box 1 can contain, for exaample, three one-phase socket outlets 2 of 16 A each, but can alternatively contain two three-phase socket outlets of 32 A each, or one three-phase socket outlet of 63 A.
The substantially parallelpipedical terminal box 1 has bent and welded-together walls of sheet steel and a coverplate 5 likewise of sheet steel, which is connected by hinges 6 to one short side wall 7 of the housing and in closed position also rests on the upper edges of the long side walls such that vehicles can be driven over the coverplate 5. The hinges 6 can be designed in a manner known per se such that the maximum opening angle of the coverplate 5 is less than 90.degree., which means that on being opened the coverplate cannot be set in a stable position. A maximum opening angle of less than 90.degree. can also be achieved by such a hinge arrangement as is shown in FIG. 2. As a result, once the coverplate 5 is not retained in open position it will fall by gravity into closed position in which the coverplate 5 is besides automatically locked, for example, by means of a latch 8. Thus, the coverplate 5 is self-closing and can only be opened by means of a key.
The bottom 9 of the box is inclined towards a drain hole 10 which is surrounded by a flange 11 to which there can be mounted a drain pipe 12 extending outwardly to the edge of the quay.
The other short side wall 13 of the box is deflected outwardly at an angle at its upper portion such that a slot-shaped opening 14 is formed
