Abstract
A fixture assembly having a self-aligning chain and a fixture suspended by the chain are disclosed. The chain has a top link connected to a point of attachment and a bottom link connected to the fixture. The chain has at least one juncture between the top and bottom links. The juncture has first and second link-ends. The first link-end is configured in the shape of a vee with diverging legs and spaced-apart edges extending longitudinally along the legs. The second link-end has a portion nestled into the vee of the first link-end contacting the vee of the first link-end at four contact points, each edge of the first link-end having a contact point. All links of the chain are connected by said juncture thereby restraining the fixture from turning with respect to its at-rest vertical axis or attitude. The present invention also resides in a ceiling fan assembly having a ceiling fan and a chain suspending the fan. When the fan is turned on, the rotating blades create a torque that tends to rotate the fan housing in a direction opposite to that of the fan blades. The chain when pulled downwardly by the weight of the fan is configured to resist this rotation.
