Tool to conduit joint for vacuum cleaner, comprises tubular mouth on tool superstructure, complementary rim on conduit and peripheral spring in mouth which permits some relative rotation

摘要

The tool (12) typically a brush (18) is connected to a conduit (14) by a mouth with two concentric stub tubes (36,42) which engage with a complementary tube (25,50) and rim (40) on the conduit. A peripheral spring (30) located between the stub tubes meets tool and conduit stops (32,33) at each end and this enables the tool a measure of rotation relative to the conduit with spring return An Independent claim is also included for : A vacuum cleaner which is equipped with the tool/conduit joint
