Patent 10165921 was granted and assigned to Dyson (company) on January, 2019 by the United States Patent and Trademark Office.
A handle assembly for a vacuum cleaner that includes a handle attached to a duct assembly. The duct assembly includes a first duct and a second duct, and the first duct pivots relative to the second duct about a pivot axis. The first duct and the second duct each have an arcuate section that arcs about the pivot axis. Pivoting the first duct relative to the second duct then causes the arcuate section of one of the ducts to move in and out of the arcuate section of the other of the ducts.
