Definitions

  • Overhead spot and track lighting installations utilise a form of channelled power supply railing into which hanging fittings are plugged at selected positions. Power engagement for. a fitting is effected by insertion of a plug into the track channel and twisting through 90°. Examples of such devices can be found in U.S. Patent Specifications Nos. 4,217,018 and 3,639,885, and Australian Patent No. 465,798. In all these instances electrical conductors are provided to either side of an entrance slot and in view of the elevated position of this rail no special safety precaution is taken, for instance against prying children. Other rails, or ducts, for supply of electrical- power, lighting etc. has been proposed for installation in a low-down position, see for example published Australian Patent Specification No.

  • Fig. 1 shows in perspective a first embodiment of an inflexible electrical supply rail constructed according to this invention and shown traversing an inside corner of a room;
  • Fig. 2 shows a typical corner piece that may be used therewith;
  • Fig. 3 shows a fragment of the supply rail to an enlarged scale;
  • Figs. 4, 4A and 4B show an end elevation of the supply rail of Fig. 3, and enlarged details thereof;
  • Fig. 5 is a perspective view of another embodiment of a flexible electrical supply rail shown forming part of a skirting board extending around two corners of a room;
  • Fig. 6 is a transverse section through a skirting board incorporating an electrical supply rail of this invention
  • Fig. 7 is a side elevation of an electrical branching device that may be utilised with the electrical supply rail shown in Fig. 6;
  • Fig. 8 is a transverse section through the electrical supply rail with the branching device inserted
  • Fig. 9 is a similar view with a telephone plug inserted into the electrical supply rail.
  • Fig. 10 is a similar view of a different form of electrical supply rail.
  • the electrical supply rail system of the invention consists of substantially inflexible elongated sections 10 and 11 which may serve entirely as a skirting board for a room.
  • the sections 10 and 11 are preferably composed of plastics material and are angularly disposed at a corner of the room and interconnected by a corner piece 12 having sets of prongs 13A, 13B and 13C which provide electrical conduction through the piece 12 and fasten the sections 10 and 11 together.
  • Each section 10 or 11 has at least one longitudinally extending channel 14A, 14B or 14C which by the invention is composed of a horizontal slot 15 having a flat floor 16 which may be horizontal, but preferably has a slight fall towards the front face 10A, or llA, of the respective section.
  • Each channel 14A, 14B or 14C also has a roof 17 and an inner end 18 and has an exposed mouth at the front face, 10A or 11A, of the section 10 or 11.
  • a rear face 19 is juxtaposed to the wall 20.
  • a plurality of longitudinally extending overhead, substantially vertical, spaced passages 21 communicate with and extend upwardly through the roof 17 of each channel 14.
  • the roof 17 is located: within a lateral recess 22 in each slot 15.
  • electrical conductor bars 23, shown more clearly in Fig. 4A are embedded in the side wall 24 of the passage 21.
  • the bars 23 extend _ longitudinally for the length of the section 10 and are composed of copper strips, or other electrically conductive material, embedded by their longitudinal edges 23A.
  • the inlet end of each passage 21 is provided with a flexible restriction 24 shown in Fig. 4B.
  • the restriction 24 may be formed as a feather edge in the moulding of the section 10 or 11. It will be appreciated by this construction of the sections 10 and 11 that the electrical conductors 23 are well concealed within the body of the electrical supply rail section 10 or 11 and are secure against prying children. Furthermore, in the event of liquids being splashed, or being dispensed, in the neighbourhood of the rail so that they might enter any one of the channels 14, the liquid will drain from the slot 15 without affecting the function of the rail or the creation of a hazardous condition.
  • FIG. 5 and 6 Another form of electrical supply rail 25, which is flexible, is shown in Figs. 5 and 6. It may be composed of extruded flexible themoplastic material with flexible conductor bars 26 embedded therein during extrusion, or , deposited subsequent thereto. When so formed the rail 25 may be bent around outside or inside corners 27 and 28 of walls 20 and form only a central portion of a skirting 29. An upper timber beading 30 and a lower mitred kick plate 31 may complement the rail 25. Outside, or inside, corner pieces 32 and 33 may be clipped over the rail 25 at the corners 27 and 28 for enhanced appearance. A strip of flexible cover insert 34 may be press fitted into the channel 14 of this, or the : previous, embodiment for added security.
  • the rail 25 may be secured to the wall 20 by nails, or screws, at the points 37 shown in Fig. 6. 0
  • the rail 25 of this embodiment has two channels 14A and 14B, with the former provided with two passages 21.
  • the conductor bars 26 are positioned within grooves 38 located on those side walls of the passage 21 which lie closest to the front face 25A of the rail 25. This 5; affords even more safety to the system.
  • the channel 14A may serve for supply of mains power.
  • the latter channel 14B has a peaked roof 17 with separate conductor bars 26 and may serve for the supply of telephone signals in a manner * described hereafter.
  • an electrical branching device such as power sockets 36 similar to those shown in Figs. 1, 5, 7 and 8, may be utilised.
  • the sockets 36 shown are designed for insertion within a channel 14 and 0 may have two or more tines, or prongs, 39 radially extending from an axial stem 40.
  • the stem 40 is hollow to house at its distal end 41 a button 42 depressible against the action of an internal helical spring 43 (Fig. 8).
  • the head 44 of the socket 36 is provided with independent terminals 45 5 electrically connected to the tines 39 which serve as conductive wipers.
  • the end of the button 42 engages with the inner end 18 of the slot 15.
  • the socket is positioned so that the tines 39 are longitudinally aligned with the channel 14A, i.e. horizontal, and by depression of the socket 36 against the spring action of the button 42 the tines 39 may be brought into alignment with respective ones of the passages 21.
  • the tines 39 can be caused to engage with the electrical conductor bars 26 as shown in Fig. 8.
  • the tines 39 are caused to bear with force upon the conductor bars 26 for good electrical contact. As shown in Fig.
  • an earth bus 46 is incorporated at the ' end 18 of the channel 14 and one of the electrical connecting leads 47" t ⁇ the, terminals 45 of the socket is wired to a conductive cap) on the button 42 while the remaining leads 47 are wired to.the inner ends of the tines 39.
  • Axial displacement of the socket 36 when inserted is resisted by the lateral enlargement 48 on the stem 40 which is accommodated within the recess 22 of the channel 1 .
  • the three channels 14A, 14B and 14C shown ' in Figs. 1, 3 and 4 may be utilised for the supply, respectively, of mains power, telephone and stereophonic audio signals. More or less channels may be incorporated within a supply rail, and other forms of electrical signals may be conveyed thereby.
  • the supply rail may comprise only a single channel 14 with each of the passages 21 mounting a plurality of conductor bars 26 relevant to a respective function.
  • one passage 21 may provide conductor bars 26 for supply of telephone connection
  • a second one may supply through four connector bars 26 stereophonic audio signals
  • a third passage 21 may comprise two conductor bars 26 for supply of television signals.
  • a separate channel 14 will usually be required for the supply of electric mains power. To effect : connection to such conductor bars 26 a different method of plugging in will be required depending upon the form of signal required for take-off.
