Definitions

  • This invention relates to an electrical distribution track in which electrical conductors are enclosed in a duct having an aperture allowing access to the conductors for electrical connection to a switch or the like mounted on the track. It is especially but not exclusively applicable to domestic mains distribution systems in which a plurality of switches or other accessories are to be connected to the conductors at different locations.
  • the track shall be able to receive accessories which are of a design compatible with electrical equipment which is already in use, such as the British Standard 13-amp distribution system.
  • Australian Patent Specification 25369/71 describes an electrical skirting duct system, which may be formed of aluminium extrusion or plastic moulding, comprising a channel shaped duct for wiring having overhangs on each side of the duct, an upstanding channel in the base of the duct, the width of the open mouth of the duct being such that a standard electrical fitting can seat on the outside surface of the overhangs; and the position of the upstanding channel being such that the electrical fitting can be secured to the duct by screws passing through the electrical fitting and screwed into the upstanding channel, and metal cover strips closing the front of the duct except for those parts where the electrical fitting has been inserted.
  • US-A-3262083 describes an electrical raceway including a retaining clip to be mounted on a wall surface and an ornamental cover member proportioned to be installed against the wall by snapping the cover member over the retaining clip. Electrical outlets are screwed to the retaining clip while they are held in position by the facing member.
  • an electrical distribution track comprising a longitudinal hollow duct of electrically insulating material
  • the accessory may be a switch socket or other device such as a circuit-breaker.
  • the duct may generally be attached directly to the surface of a wall or like supporting structure to which the track is attached.
  • the duct has upstanding outer side walls covering the duct side walls which come into contact with the accessory and the outer walls engage the cover means.
  • the duct itself is thus completely enclosed and protected against damage and entry of unwanted material such as water which might come into contact with the conductors.
  • the cover means is attached to the duct side walls by means of beads and grooves forming a snap fit.
  • the cover means may comprise a single cover member extending over the opening and duct side walls and abutting the outer side walls of the duct; alternatively it may comprise a central cover part extending over the opening and separate side covers, which may engage the central cover by means of flanges fitting into grooves.
  • the use of beads and grooves for fitting the covering means in place may render the use of screws unnecessary.
  • the accessory may itself have flanges engaging the edges of the duct walls or it may be mounted on a plate which engages the duct side walls.
  • the use of a plate allows many types of standard accessory, which are not provided with flanges, to be mounted on the track.
  • the accessory or plate carrying the accessory, may be clamped against the edges of the duct wall by screws or it may be held in place on the duct by the covering means itself.
  • the conductors may be mounted on the rear - wall of the duct opposite the opening and the rear wall of the accessory may comprise terminals, for example sprung fork terminals, to make electrical contact with the conductors when the accessory is mounted in the duct.
  • the track shown in Figure 1 comprises a longitudinal channel-shaped duct 1 of uniform cross-section formed of electrically insulating plastics material such as polyvinyl chloride. It may be made by extrusion.
  • Duct 1 comprises a flat base 2 provided with upstanding portions forming grooves 3a, 3b and 3c containing respective longitudinal copper conductors in the form of bus-bars 4a, 4b and 4c.
  • the bus-bars 4 are narrower than the grooves 3 and are held in the grooves by cleats, one of which is shown in Figure 1, distributed at intervals along the grooves.
  • Duct 1 has upstanding side walls 6 provided at their edges with continuous longitudinal grooves 7 defined by longer outer walls 8 and shorter inner walls 109.
  • the grooves 7 have a portion 110 ( Figure 2) of increased width extending along the groove.
  • the track also comprises a longitudinal cover for closing the duct.
  • the cover comprises a flat front 111 provided with a flange at opposite longitudinal edges.
  • the flanges at opposite edges are identical and as best seen in Figure 2 each flange extends sideways from front 111 and is provided with an outwardly facing groove 112 formed by wall 113 having a lip 114 extending into the groove.
  • the flange also has an inwardly facing groove positioned to receive wall 109 of the duct when the cover is applied to the duct.
  • One wall defining groove 115 has an inwardly projecting bead 116 which is bifurcated and has bulges 117 dimensioned to fit into portion 110 of the groove 7.
  • Wall 8 of the duct is shaped as shown to engage part 118 of the flange and a wedge-shaped gap 119 is provided between these members.
  • the flange is also provided with an outwardly facing groove 120 opposite the bead intended to receive screws 121, of which one is shown in Figure 1.
  • the screws are intended to penetrate the bead inside groove 7 and push bulges 117 apart to secure the cover on the duct.
  • Holes in the bottom of groove 120 may be provided to receive the screws, or alternatively the screws may be capable of penetrating the plastics material of the cover.
  • a suitable screw for this purpose has a pointed pyramidal end for cutting into the plastics material as it is inserted.
  • the duct 1 is also provided with a pair of upstanding outer walls 122 which may be perpendicular to the base 2, as shown in Figure 2, or be inclined at an angle thereto.
  • the edges of walls 122 are provided with bifurcated beads 123 similar to beads 116 and a shoulder 124.
  • Outer walls 122, together with grooves 112, are intended to hold in place edge covers 125 which may be plastics material or may be of metal such as aluminium.
  • One side of the edge cover has a flange 126 having a widened edge to snap fit in groove 112 behind lip 114.
  • the other side of the edge cover has a groove 127 of part-circular cross-section to snap over bifurcated bead 123.
  • a small gap between shoulder 124 and the edge of side cover 125 is provided to receive a screwdriver blade or other tool to allow the side cover to be removed by leverage.
  • the track of this embodiment is intended to be mounted with the rear surface of base 2 in contact with a wall and grooves 128 (shown in Figure 2) are provided on the base to facilitate location of screws (not shown) to pass through the base and secure it to the wall in known manner.
  • a groove may be provided between both pairs of walls 6 and 122.
  • Grooves 128 may have holes at intervals to receive the screws, alternatively screws capable of penetrating the plastics material of base 2 may be used.
  • grooves 3a and 3c are provided with flanges 129 extending at an angle towards walls 6 to receive an edge of strips 130, the opposite edges of the strips being received in grooves 131 on walls 6.
  • the grooves are dimensioned so that the strips may be snapped into place and isolate the spaces 132 in the duct from the remainder of the duct. Spaces 132 may be used to accommodate telephone wires or other services which run along the duct and are not associated with the circuits formed by bus-bars 4.
  • the interior walls of grooves 3 have serrations extending in the longitudinal direction of the track to form internal abutments to retain the cleats holding the bus-bars.
  • Two types of cleat which may be used in these grooves are shown in Figures 12 and 13 respectively.
  • the outer walls of the cleats have outstanding flanges 38 to engage the abutments to hold the cleats in place in the grooves.
  • the rearward surfaces 39 of the flanges are inclined so that the cleats may easily be inserted into the grooves by pressing.
  • the interior slot of the cleat of Figure 12, intended to contain the bus-bar, is of uniform width so that the bus-bar may have a width nearly equal to the overall length of the cleat.
  • the cleat of Figure 13 has a shorter internal slot 40 terminated by constriction 41 to receive a bus-bar of lesser width.
  • Figure 2 shows one cleat of the type shown in Figure 12 holding a bus-bar 4 in place. Cleats are provided at intervals along each bus-bar.
  • FIG. 1 shows a 13-amp plug socket 151 mounted in the track.
  • This socket is of standard internal construction but is connected to the bus-bars 4 by forked connectors, extending behind the socket to engage a respective busbar.
  • the forked connectors are dimensioned to enter the grooves 3 and bracket the bus-bars, the prongs of the forks being inwardly sprung so that they clamp the bus-bars between the prongs to establish a reliable electrical contact between connector and bus-bar.
  • the connectors connect the socket apertures receiving the plug pins to the bus-bar.
  • the socket itself has a front surface 152 which, when mounted on the track, projects slightly above the surface of cover 111.
  • the socket may be mounted between two lengths of cover 111 in the longitudinal direction, as shown in Figure 1.
  • Its longitudinal side surfaces 153 are aligned with corresponding side surfaces of cover 111 and engage side covers 125 when the track is assembled, the side covers extending beside both the cover 111 and the socket.
  • Side surfaces 153 have flanges 154 which abut the edges of walls 6.
  • the sides of the socket transverse to the track are provided with outstanding flanges 155 which, when the track is assembled, extend behind and engage the inside surface of cover 111.
  • the socket is thus clamped in place on the track by the cover 111 engaging flanges 155.
  • Figure 3 shows only one (the upper) longitudinal side of the socket; the lower side is engaged with the track in the same way.
  • switches and circuit-breakers may be similarly mounted in the track provided that they have similar flanges 155.
  • FIG. 4 and 5 A method of mounting a standard accessory, which need not be manufactured with flanges as in the above described embodiments, is illustrated by Figures 4 and 5 with reference to the embodiment of Figure 1.
  • the front plate 156 of the accessory is mounted in front of the track covers, to overlap the edges of the adjacent covers 111 and side covers 125. It is held in place by screws 157 passing through holes 158 in a rectangular mounting plate 159 which has a generally square central aperture 160 to accommodate the working parts of the accessory on the rear surface of plate 156.
  • the edges of the plate are provided with holes 161 positioned so that when the plate is positioned on the track as shown in Figure 4 the holes are aligned with the groove in wall 6 and the mounting plate may be secured to the track by screws 162 passing through holes 161 and engaging the inner surfaces of the grooves.
  • the mounting plate On assembly of the track the mounting plate may first be attached in this way, followed by mounting of the cover 111 and side covers 125 and mounting of the front plate 156 using screws 157.
  • the mounting plate may have flanges at its edges to increase its rigidity.
  • This method of mounting may be used for any standard accessory of appropriate dimensions which has holes to receive screws 157 at the required locations.
  • the duct 1 When the track shown in Figure 1 is installed in a building the duct 1 is first attached to the surface of a wall or like supporting structure by screws applied to grooves 128 ( Figures 1 and 2). The bus-bars are then mounted in their grooves using cleats spaced at intervals (if they are not mounted in the duct already) and if desired any telephone cables or the like which are required may be passed through spaces 132 which are then closed by application of members 130. Electrical accessories such as plug socket 151 may then be positioned at any desired point along the duct with their fork terminals in contact with the bus-bars. As shown in Figure 1 the three bus-bars are positioned unsymmetrically with respect to the longitudinal axis of the duct to avoid any risk of an accessory being mounted upside-down. Any accessories requiring use of a mounting plate 159 are similarly mounted at any desired position. The main cover 111 and side covers 125, may then be applied as shown in Figure 1 to close the duct: the covers are easily cut to the appropriate length on site.
  • the duct and covers When the track is installed the duct and covers may be supplied in standard lengths and it may be necessary to join adjacent pieces of duct and cover end-to-end, in which case the joint should be protected especially to prevent entry of water or other unwanted matter from the outside. Such protection may be provided by a joint cover 171 shown in Figure 1 and in Figures 6-8.
  • Figure 6 shows the outside surface of the joint cover as seen in Figure 1 but without the intervening cover parts
  • Figure 8 is a section through the joint cover
  • Figure 7 is a view of the joint cover seen from the side.
  • the joint cover comprises a strip of plastics material forming side walls 173 which fit over the walls 122 of the duct and central portion 172 extending between the walls 122 of the duct and shaped so that the outer surface of the cover joint is substantially flush with the outer surfaces of the main cover 111 and side covers 125.
  • the inner surface of the joint cover is provided with projections 174 to enter grooves 7 of walls 6 and the adjacent parts of the inner surface are shaped to abut the edges of walls 8 and 9 around the grooves. Grooves 175 are provided to engage the bead 123.
  • the joint cover has flanges 177 to extend sideways to fit underneath the ends of the adjacent covers so that the latter hold the joint covers in place and prevent access to the interior.
  • Figure 1 also shows an end plate 180 which is of similar construction to joint cover 171 except that it also comprises a wall closing off the open end of the track.
  • Figures 9 and 10 show a corner-piece which may be used when the surface-mounted power track of Figure 1, mounted on a wall, is to continue around a convex rightangle corner.
  • Surfaces 181 of the corner-piece engage the wall and surfaces 182, 183 provide a continuation of the outer surfaces of the covers 111 and 125 around the corner.
  • Surfaces 182 are substantially flush with the outer surfaces of the covers 111, 125 of an adjacent length of track and projections shown generally at 184 engage the adjacent track behind the covers to join the track to the corner-pieces.
  • the interior surfaces behind surfaces 182 are of similar profile to the inner surface of covers 111 and 125 to engage the end portions of adjacent ducts 1 and clip the corner-piece to the track.
  • Figure 11 shows a corner-piece for a concave rightangled corner.
  • Surfaces 185 will engage the walls of the room and surfaces 186 will be flush with corresponding surfaces of the covers of the adjacent track lengths.
  • Projections 187 extend behind the adjacent covers, as in the corner-piece of Figure 9.
  • the adjacent duct 1 With both these types of corner-piece the adjacent duct 1 will extend up to the corner itself, the bus-bars of the adjacent ducts being joined by suitable connectors at the corner, and the ends of the ducts at the corner are covered by the corner-piece.
  • circuit accessories including circuit breakers
  • the accessory When the accessory is a socket of the type shown current is supplied from the bus-bars to the point of use through a plug inserted in the socket.
  • the accessory With other types of accessory the accessory itself may be provided with cables running to the point of use and these cables may extend from the front of the accessory, which is exposed when mounted on the track. Alternatively cables may extend from the back or a side of the accessory which are enclosed in the assembled track and holes in the duct, and channel when used, are then required to allow passage of the cables. These holes may be provided by knock-out portions formed in known manner in the duct and channel.
  • the duct, bus-bars, track cover and channel may all be supplied in a variety of standard lengths or may be cut to any required length on site so that the length of the track is easily adapted to any given requirement, for example installation in a room of a house where the length of a wall is non-standard.
  • the switch sockets or other accessories may be mounted on the track at any arbitrary point so that they may be positioned to suit the requirements of an individual customer.
  • the track cover may then be cut to length using a tenon saw or the like and mounted in place on the brackets.
  • the various components may be assembled in a workshop, for example to a previously determined arrangement thus saving assembly time on site.
  • any number of accessories may be mounted on the same track, either side-by-side or spaced along the track, and spaces between the accessories are occupied by the track cover so that the track is completely enclosed.
  • the snap-on track cover is held firmly by beads in grooves so that it will not be removed accidentally and there is little risk of unauthorized removal, for example by a child.
  • the bus-bars may be designed to carry any required current, for example up to 60 or 100 amps. As shown in the drawings, the distance between bus-bars 4a and 4b may differ from that between 4b and 4c. This unsymmetrical arrangement avoids any risk of a switch or other accessory being mounted on the track upside-down.
  • bus-bars intended for use as live, neutral and earth in a domestic power supply but substantially the same arrangement may be used with a different number of bus-bars for example in a polyphase system.
  • the dimensions of the track may be such that switches and other accessories mounted on it may be of standard types and sizes which are already established in the art. The track will then be compatible with existing equipment.
