Quick connect rotary bearing for a vacuum cleaner

摘要

A rotary bearing is disclosed for pivotably connecting a journal to a similar cylindrical saddle formed in a chassis member. The rotary bearing is provided with an annular sleeve having inner surface sides to freely rotatably cooperate with the journal. The annular sleeve outer surface has affixed to it an arcuate flange extending radially outward and about a limited portion of the sleeve periphery. The flange includes a relatively thin web section and a thicker head portion spaced radially outward therefrom to enable the flange to interconnect with the arcuate slot formed in a semi-cylindrical saddle surface. The rotary bearing can be quickly installed and removed without the use of fasteners or installation tools and is particularly suitably adapted for use in mounting an upright vacuum motor/fan assembly to the cleaner head chassis.
