Suction head for floor vacuum cleaners

Abstract

A suction head for floor vacuum cleaners has a unitary plastic housing ( ) containing a suction channel ( ), and a bottom plate ( ) arranged on the underside of the housing and having a suction mouth ( ). The suction mouth adjoins a vertically aligned, box-shaped connection element ( ) of the suction channel and feeds into a bottom channel ( ) of the bottom plate ( ). The bottom plate ( ) is pivot-mounted both on the connection element ( ) of the suction channel and also at the end side on the inner surfaces of the plastic housing ( ). For this purpose, the box-shaped connection element ( ) contains transverse bridges ( ) that define the suction channel laterally and which have bottom edges designed as bearing surfaces ( ) rounded in a curved manner. The bottom plate ( ) is supported on the curved, rounded support surfaces ( ) of the connection element ( ), and rotatably interlocked with the wall surfaces of the connection element ( ) extending parallel with the transverse bridges.
