Definitions

  • This invention relates to lighting track systems, and in particular to systems of the kind in which lights or other electrical devices are electrically connected to a track incorporating power supply means, by means of a mounting device which also retains the device in position, on the track.
  • the invention relates particularly (although not exclusively) to lighting systems of the low voltage type.
  • a lighting track system comprising a mounting device adapted for cooperation with a track incorporating electrical contact means, the mounting device comprising a carriage including contact means adapted to cooperate with the electrical contact means of the track, and retaining means,adapted to hold the carriage in a desired position on the track, and comprising displaceable locking means which can be moved between a first position in which the carriage can be engaged with the track, and a second position in which the locking means locks the carriage to the track.
  • the track has a longitudinally extending recess which incorporates the electrical contact means, and said locking means is adapted to be moved between a retracted position (the first position) in which the carriage can be inserted into or released from the track, and a protruding position (the second position) in which they engage with corresponding opposed internal faces of the recess.
  • the locking means comprises at least one set of oppositely facing abutment members formed from a relatively resilient material, so as to be inherently biassed either towards the engaged position or the released position; and at least one set of cooperating camming means, whereby relative movement of the locking means and the camming means results in displacement of the locking means between the locked and released position.
  • each set of abutment members there are two sets of camming means for each set of abutment members, the abutment means being movable between the released position, in which they are held by one set of camming means, and the engaged position in which they are held by the other set of camming means.
  • each set of abutment members comprises at least one pair of mutually opposed wings or claws which are resiliently biassed towards one of the said positions
  • the camming means comprises a tapered member which is slidably engageable with the said members, so as to urge them towards the other of the said positions.
  • the abutment members comprise at least one pair of mutually opposed wings or claws whcih are resiliently biassed apart, towards an outward locked position, and two sets of camming means one set comprising a tapered slot, the wings or claws being mounted on a sub-assembly of the carriage and being slidable in the said tapered slot; so as to be urged together by the taper of the slot at one extreme position, whilst the other set of camming means comprises a tapered member which projects between the wings at the other extreme position so as to hold them apart.
  • a track 2 of generally conventional form comprises an elongate body which may for example be an aluminium extrusion, having a generally circular external profile, and a longitudinally extending recess 4.
  • the opposite internal faces of the recess 4 carry conductor wires 6 and 8 whcih are mounted in respective electrically insulating housing strips 10 and 12, which are retained in correspondingly shaped re-entrant slots in either side of the recess.
  • a carriage 14 is adapted to be releasably located in the track, as explained in more detail below, and carries a contact assembly 16, adapted to make connections with the conductors 6 and 8 of the track, and a downwardly dependent mounting barrel (18) having a threaded lower end which carries a light fitting (not shown).
  • the electrical connections between the fitting and the track are made via a pair of wires 20 whose upper ends are suitably connected to respective downwardly extending contact members 22 of the contact assembly 16.
  • the upper ends of the contact members comprise enlarged plate-like portions 24 whose upper and lower edges are inwardly flanged at 26.
  • a support member 28 for the contact assembly comprises a generally T-shaped body, having a downwardly dependent stem 30, each side of which is formed with a channel which receives the downwardly extending end of the corresponding contact member 22.
  • the head 32 of the contact support member 28 is somewhat enlarged in cross-section, and is formed with a slot 34 on each side which receives and locates the flange 26 of the corresponding contact member.
  • the top of the head 32 also carries endwise projecting tapered portions 33 described in more detail below, and has downwardly dependent lug positions 35 at each end which lock the contact member into a slot 37 in the centre of the carriage.
  • the contact members and the support member 28 are securely held in location with one another.
  • this assembled condition brings the contact plate members 24 into approximate alignment with the corresponding side faces of the carriage 36 which in use, extend into the recess 4 of the track 2, so that the contact members 24 are brought into contact with the conductors 6 and 8 in the track.
  • the contacts 24 are stamped from a suitably resilient metal, and somewhat convex in cross-section so that they protrude outwardly from the head 32 of the contact support member 28, they are urged into intimate contact with the conductors of the track.
  • the sub-assembly 40 comprises a main body forming a slider, whose upper surface is formed with a longitudinally extending recess 42 which is shaped to cooperate with the underside of the end portion 44 of the carriage, which, as can be seen from the drawing, is of generally "top hat” shaped cross-section.
  • the upper surface of the slider carries a pair of upwardly extending, wing like locking members 46, 48, having oppositely facing flanged projections 50, 52 at their upper ends.
  • the wing members are staggered longitudinally of the slider, so that the "leading edge" of one projection 50 is approximately level with the "trailing edge” 56 of the other projection 52.
  • the slider can be assembled onto the carriage 14 as illustrated at the righthand side of Figure 1, by squeesing the wings together and inserting them through the base of the tapered slot 38, at the inner end of the slot which is wider. The natural resilience of the material then causes the wings to move outwardly so that the flanged portions 52 and 54 hold the slider in position on the carriage, again as illustrated on the righthand side of Figure 1.
  • the slot 38 has a relatively wide inner section and a relatively narrower outer end portions, there being a short tapered region 58, 60 on each side of the slot adjacent each end.
  • the positions of the tapered regions 58 and 60 are staggered in the same relationship as the locking wings 46 and 48 of the slider, and thus it will be seen that when the slider is in its installed position, the action of moving the slider 40 in an axially outward direction urges the two wings 46 and 48 laterally inwards, so that the assembled carriage can then be offered up for insertion to the track.
  • the wings 46 and 48 will be allowed to move laterally outwards, so as to engage against the opposed internal side walls of the track.
  • the arrangement of the conductors 6 and 8 and their corresponding mounting strips 10 and 12 is such that recesses are formed above them to receive the outer extremities of the wings 46 and 48 of the slider.
  • the wings In order to securely lock the wings in this position, they also engage around the tapered end projections 33 of the head 32, in the inner position, Figure 3a, and again as will be seen more clearly from Figure 3b, the projections 33 are so shaped on each side that they match the offset of the wings.
  • Figure 4 shows an alternative form of the invention, which again includes a track 2 having internal contact members 6 and 8, a mounting member 18 for a light fitting, a carriage 14, and a pair of opposed contact members 24 on a contact support member 28.
  • the general relationship of the parts is similar to that of Figure 1, but the arrangement for locking the carriage into the track is slightly different, as will be explained in more detail below.
  • each outer end 80 of the carriage 40 is bifurcated, to form a pair of parallel arms 82, and a slider 84 is formed with a vertically upstanding central flange 86 which fits between the arms 82.
  • a pair of locking wings 88 are integrally formed with the carriage 14, and have laterally outwardly extending flanges on their upper ends.
  • a tapered formation 90 carried on the upper end of the flange 86 of the slider, is urged between the wings 88 as the slider is moved towards its axially innermost position, as shown at the righthand side of Figure 4. It will thus be appreciated that the carriage can be inserted onto the track, with its sliders in axially outward positions, and the sliders subsequently moved inwards to lock the wings into position against the opposed internal side walls of the track 2.
