DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[0017] As illustrated in Figure 1, a track lighting system 10 according to an embodiment of the present invention comprises a number of track elements 12 supported by posts 14 secured to a ceiling (not shown).
[0018] The track elements 12 may be linear or may include curvilinear sections. Figure 2, for example, illustrates a right-bended track element 12a and a left-bended track element 12b.
[0019] As shown in the cross-section of Figure 3, the track element 12 comprises a vertical rail-type body extrusion 16 wrapped around an insulation extrusion 18, which secures live wires 20 located on a vertical axis relative to the ceiling (not shown). A ground wire 22 is secured into a groove of the body extrusion 16.
[0020] The vertical body extrusion 16 may be made in aluminum, the insulation extrusion 18 may be made in PVC, and the wires 20 and 22 are copper wires for example.
[0021] Track elements 12 are assembled together by vertical flush track junctions 24 shown in Figures 4 and 5.
[0022] As seen in Figure 4, a vertical track junction 24 comprises a junction body 26 with a first and a second fastening apertures 28 and 30 on each wing thereof. The junction body 26 has a shape matching an interior female shape of the insulation extrusion 18 of the track elements 12: the first wing of the junction body 26 with the first fastening aperture 28 comes into place within an interior 36a of the insulation extrusion of a first track element 12a, and the second wing with the second fastening aperture 30 comes into place within an interior 36b of the insulation extrusion of a second track element 12b (see Figure 4).
[0023] Each one of the track elements 12a and 12b comprises fastening apertures corresponding to the fastening aperture 28 and 30 of the junction body 26 respectively, allowing using fastening means such as screws 32 and 34 to secure the junction body 26 to the track elements 12a and 12b respectively.
[0024] When thus lapped between the track elements 12a and 12b, the junction body 26 receives a shell cover 27, further bridging the two joined track elements 12a and 12b together on an opposite side thereof. The shell cover 27 further holds into place a live junction clip 38 and a junction ground clip 40. The shell cover 27 may be secured by means of a pressure screw 42 for example (see Figure 5).
[0025] The track members thus joined together form a track member assembly, which is secured to the ceiling by the posts 14, located at intervals along a length thereof. At least part of the posts 14 are anchor posts 14a, while other are feeding mounting posts 14b, as will now be described.
[0026] As illustrated in Figures 10, an anchor post 14a comprises a member 122 having a dimension between a first end 124 for fixing to the ceiling and a second end 126 for fastening to the track member assembly. The member 122 may be of an adjustable length between these two ends, so as to allow selecting a height of suspension of the track member assembly.
[0027] The first end 124 comprises a ceiling cone 128 receiving a lock screw 130 for a ceiling support screw 132 mounted into the ceiling through a ceiling support 134. The ceiling cone 128 and the ceiling support 134 may be made in a plastic material such as ABS for example. A further anchor between the ceiling and a hollow panel may be used to ease fixing the screw 132.
[0028] The second end 126 for fastening to the track member assembly comprises a clip on rod with plyer parts 138 without any electrical wire therein.
[0029] As best seen in Figures 10B-10D, for securing a track member 12, a lower clipping part 212 of the clip on rod is inserted in the female part of the track element 12, both having complementary shapes. The lower clipping part 212 automatically engages the female part of the track element 210. Adjustment of a lock screw 136 allows further securing the clip on rod to the track element 12.
[0030] The feeding mounting posts 14b are mounted to the ceiling by ceiling-feed mounts 15, as now described in relation to Figure 6.
[0031] The ceiling feed mount 15 comprises a canopy 44 having a passageway 46 for a wire (not shown). The canopy 44 is secured to the ceiling, or to a generally horizontal surface for example, by means of fastening means 52 such as stud screws.
[0032] As shown in Figure 6, the wire may be protected within a tube 50, which may be threadedly secured on a top part thereof to the passageway 46 of the canopy 44 and thredeadly secured to the junction cone 56 via a bushing 58 for example. A length of the tube may be adjusted depending on a desired height of suspension, and, correspondingly, a clip, such as a plastic ABS clip may be used to allow adjusting a length of the wire 48 inside the member 122.
[0033] The junction cone 56 allows a junction to the one-piece mounting adaptor 62, which will be described in details in relation to Figures and 6-7.
[0034] The one-piece mounting adaptor 62 comprises a body receiving the wire 48, a junction part 64 comprising an aperture 63 for connection to the wire 48 coming from the ceiling feed mount 15, and a track clipping part 72.
[0035] The track clipping part 72 receives the rail-type body extrusion 16 of a track element between a crook-like edge 68, which comes into a locking position on a first lip 17 of the rail-type body extrusion 16 (see Figure 3) and a flange portion 70, which comes in abutment and is clipped by pressure on a clipping element 71 with a second lip 19 of the rail-type body extrusion 16 (see Figure 3), so that the track clipping part 72 of the mounting adapter 62 comes in contact with the interior surface of the insulation extrusion of the track element. A ground link clip 67 is provided inside the crook-like edge 68 (see Figure 7A).
[0036] The flange portion 70 may further comprise a locket tongue 73 (see Figures 11 and 12), which flips back on the second lip 19 of the rail-type body extrusion 16 and locks itself into a groove 77 provided on a back face of the rail-type body extrusion 16, in such a way as to secure the mounting adapter 62 onto the rail-type body extrusion 16.
[0037] The track clipping part 72 of the mounting adaptor 62 (see Figures 7) has a shape complementary to that of the interior female surface of the insulation extrusion of the track element, a prominent surface 74 of the track clipping part 72 corresponding to a recessing surface of the interior female surface of the insulation extrusion of the track element (see Figure 3).
[0038] Retractable tongues 76 are provided in a recess of the prominent surface 74 of the track clipping part 72. These tongues may be moved in a connecting position or in a disconnecting position by an action of an arm 78. In the connecting position, the tongues 76 extend out of the prominent surface 74 of the track clipping part 72 so as to establish an electrical contact with the live wires 20 nested in the insulation extrusion of the track element. In a disconnecting position, the tongues 76 recoil in the recess of the prominent surface 74, thereby disconnecting the wires of the track element.
[0039] As may be seen in Figure 1, a number of lighting devices such as spots or pendants 80 may be suspended along a length of the track system 10, by using suspensions 82 as illustrated in Figure 8.
[0040] The suspension 82 comprises a suspension adapter 84 between the track member assembly and the lighting device (not shown in Figure 8).
[0041] As seen in Figure 11, the suspension adaptor 84 is essentially identical to the mounting adaptor 62 between the ceiling feed mounts 14 and the track described hereinabove. The suspension adaptor 84 comprises a junction part 86, a body part 88 receiving a wire 90 going to the lighting device to be suspended, and a track clipping part 92. The track clipping part 92 clips the rail-type body extrusion 16 of the track element in the same way as described hereinabove in relation to the mounting adaptor 62.
[0042] Tongues 94 are provided in a recess of a surface 96 of the track clipping part 92. These tongues may be moved into a connecting position and into a disconnecting position by an action of a swindle arm 98. In the connecting position, the tongues 94 extend out of the surface 96 of the track clipping part 92 and establish an electrical contact with the wires in the body 88 of the suspension adaptor 84, whereas in the disconnecting position, the tongues 94 are retracted inside the body part 88 of the suspension adaptor 84, thereby disconnecting the wires of the track element.
[0043] The suspension 84 adaptors may comprise a locket tongue 93, which flips back and locks itself into a median groove provided on a back surface of the rail-type body extrusion of the track member, in such a way as to secure the suspension adapter 84 onto the rail-type body extrusion.
[0044] The wires 90 may be protected within a tube 100, which may be threadedly secured on a top part thereof to a passageway of the suspension adaptor 84 via a junction cone 110 and washers 112 for example, and on a bottom part thereof to the desired lighting device, as is well known in the art. A
clip, made in BAS for example, for adjusting a length of the wire 90 may be used to adjust a height of suspension of the lighting device (not shown), as shown in Figures 9.
[0045] Locating pins 55 matching the profile of the track elements 12 (see Figures 6, 7, 8) may be used for preventing any wrong installation of a mounting adaptor 62 or of a suspension adaptor 84 on the tracks described hereinbefore, so as to respect the electric polarity and allow a correct grounding, for example.
[0046] From the foregoing, it should now be apparent that the present invention provides a versatile line voltage track (120-220V) light system allowing hanging up easily lighting devices such as spots or pendants, by essentially one type of one-piece adaptor between the track and a wire-containing element.
[0047] Although the present invention has been described hereinabove by way of embodiments thereof, it may be modified, without departing from the nature and teachings of the subject invention as defined in the appended claims.
