Luminaire connection systems
A system for connecting luminaires is provided. The system includes: a first luminaire having an end face having a first slot; a second luminaire having an end face having a second slot; a first elongated joining member having first prongs. The first slot and second slot are in laterally aligned and joined relationship define a first joining member slot having a first wedged end, and the first wedged end is shaped to provide an interference fit with the first prongs wherein advancing the first prongs against the first wedged end forces the first slot and the second slot toward each other to tighten connection between the first luminaire and the second luminaire.
1. A system for connecting luminaires, the system comprising:
a first luminaire comprising an end face comprising a first slot;
a second luminaire comprising an end face comprising a second slot;
a first elongated joining member comprising first prongs;
wherein the first slot and second slot in laterally aligned and joined relationship define a first joining member slot comprising a first wedged end,
wherein the first wedged end is shaped to provide an interference fit with the first prongs wherein advancing the first prongs against the first wedged end forces the first slot and the second slot toward each other to tighten connection between the first luminaire and the second luminaire.
2. A system according to claim 1 wherein the first wedged end comprises outwardly and downwardly angled surfaces that define a first angle equal to or greater than a second angle defined by the first prongs.
3. A system according to claim 2 wherein:
the first luminaire comprises a first crossplate that at least partly defines the end face of the first luminaire; and
the second luminaire comprises a second crossplate that at least partly defines the end face of the second luminaire.
4. A system according to claim 3 wherein:
the first luminaire comprises a pair of first sidewalls that at least partly defines the end face of the first luminaire; and
the second luminaire comprises a pair of second sidewalls that at least partly defines the end face of the second luminaire.
5. A system according to claim 3 wherein the first and second slots are formed in the first and second crossplates.
6. A system according to claim 4 wherein the first slots are formed in the first sidewalls and the second slots are formed in the second sidewalls.
7. A system according to claim 4 wherein the first slots are formed partly in the first crossplate and partly in the first sidewalls, and the second slots are formed partly in the second crossplate and partly in the second sidewalls.
8. A system according to claim 5 wherein the first elongated joining member extends into the first joining member slot to a depth greater than half of the height of the sidewalls.
9. A system according to claim 8 comprising fastening means for fastening the first elongated joining member into the first joining member slot.
10. A system according to claim 9 wherein the fastening means is selected from the group consisting of screws, snap clips and spring clips.
11. A system according to claim 10 wherein the fastening means comprise screws for fastening a flanged portion of the first elongated joining member to the crossplates of the first or second luminaire.
12. A system according to claim 11 wherein a close tolerance exists between a thickness of the first elongated joining member and a thickness of the first joining member slot.
13. A system according to claim 12 wherein a loose tolerance exists between a width of the first elongated joining member and a width of the first joining member slot.
14. A system according to claim 13 comprising:
a plurality of opposing aligning slots formed in the end faces of the first and second luminaires; and
a plurality of aligning members insertable in the aligning slots.
15. A system according to claim 14 wherein the first elongated joining member is rigid and the first joining member slot comprises a straight cross-section.
16. A system according to claim 14 wherein the first elongated joining member is flexible and the first joining member slot comprises a curved cross-section.
17. A system for connecting luminaires, the system comprising:
a first luminaire comprising an end face comprising a first slot and a third slot;
a second luminaire comprising an end face comprising a second slot and a fourth slot;
a first elongated joining member comprising first prongs;
a second elongated joining member comprising second prongs;
wherein the first slot and second slot in laterally aligned and joined relationship define a first joining member slot comprising a first wedged end,
wherein the third slot and fourth slot in laterally aligned and joined relationship define a second joining member slot comprising a second wedged end,
wherein the first wedged end is shaped to provide an interference fit with the first prongs wherein advancing the first prongs against the first wedged end forces the first slot and the second slot toward each other to tighten connection between the first luminaire and the second luminaire; and
wherein the second wedged end is shaped to provide an interference fit with the second prongs wherein advancing the second prongs against the second wedged end forces the third slot and the fourth slot toward each other to tighten connection between the first luminaire and the second luminaire.
