Patent 6925967 was granted and assigned to LG on August, 2005 by the United States Patent and Trademark Office.
The illuminated retractable leash is an animal tethering device which uses electroluminescent wire and a DC to AC inverter to illuminate not only the extendable and retractable physical tether to the animal, but also to illuminate the leash housing. Electroluminescent wire wound on a rotating spool is supplied power by an inverter circuit powered by an on board battery. A transparent spool and an at least partially transparent housing provides the capability for illuminating the housing, as well as the electroluminescent wire leash.
