Method and apparatus for hanging lighting fixtures
A modular lighting system for providing light in various areas includes one or more canopies, a set of buses, a set of hangers for supporting the bars from canopies and, optionally other supports, a set of pendants with light emitting elements and a set of hangers for supporting the pendants from the bars. The bars include two segments with conductive rails disposed or imbedded in their inner surfaces. The hangers have one or two rods and bases shaped and sized for mounting on the bars with the rods contacting the conductive rails. The hangers and bars cooperate to allow the hangers to be placed anywhere along the bars. The pendants and hangers may be sized and shaped so that the pendants trapped the ends of the hangers forming a supporting mechanical interlock therebetween. Pendants can be hanged on the bars singly, or in clusters.
1. A method of assembling features of a lighting system, said lighting system including at least one rod terminating in a rod end including a spade with a body and a shank narrower than said body and a pendant including a pendant body having a pair of blades separated by a distance smaller than the width of said body of said rod and having a top surface having an opening leading to a cavity, said opening having a cross-sectional dimension at least equal to a width of said body of said rod, said method comprising the steps of:
inserting said rod end into said opening until said rod end reaches said blades;
twisting a first time said rod about a longitudinal axis until said spade is aligned with said blades;
pushing said rod end into said cavity between said blades until said spade passes said blades; and
twisting said rod a second time about said longitudinal axis until said spade is not aligned with said blades causing said blades to trap said spade in said cavity.
2. The method of claim 1 , wherein said system includes two parallel rods, each having identical rod ends, said pendant includes two identical openings and two pairs of blades, and said method further includes the steps of inserting said rod ends simultaneously and twisting said rods said first time and said second time to cause the blades to capture the rod ends of both in said openings of said pendant of said rods.
3. The method of claim 2 , wherein said rods are attached to a head and said twisting steps include twisting said head.
4. The method of claim 1 , wherein said step of twisting a first time includes twisting the rod in a first direction and wherein said step of twisting a second time includes twisting the rod in a second direction, opposite said first direction.
