US Patent 7954976 Multi-use adaptor kit/system for recessed can fixtures

An adaptor kit or system for use with conventional can light fixtures to adapt the can light fixture for use as a hanger assembly for auxiliary fixtures, such as a hanging lamp, a flush-mounted lamp or the like, includes an expandable/retractable shoe assembly with surfaces to forcibly engage the inner surface of a can with sufficient engagement thereto to install an auxiliary fixture. In the preferred embodiment, the shoe assembly is defined by two individual shoes connected by threaded nut/screw assemblies so that the nut/screw assemblies can be adjusted to cause the shoes to extend outwardly to effect a usable mounting.
