Floor nozzle for vacuum cleaners

Abstract

A floor nozzle for vacuum cleaners has a first position for vacuuming broad floor surfaces, and a second position for vacuuming narrow floor surfaces. The floor nozzle includes a suction head that has a base area with two broad sides and two narrow sides, and a tilt joint consisting of a channel connector piece molded onto the suction head and a pivotable channel section. A pipe elbow having a curvature of essentially 90° is connected with the channel section and has a connector end for a suction pipe. The channel section is pivoted out in the first position, so that the axis of rotation of the connection between the pipe elbow and the channel section is oriented at a downward slant. In the second position, the movable channel section is pivoted into the channel connector piece so far that the axis of rotation of the connection is oriented horizontally.

1 . A floor nozzle for vacuum cleaners, having a first functional position for vacuuming broad floor surfaces, as well as a second functional position for vacuuming narrow floor surfaces, the nozzle comprising: 
 a suction head having a base area with two broad sides and two narrow sides;    a tilt joint consisting of a channel connector piece molded onto the suction head, and a pivotable channel section,    a pipe elbow having a curvature of about 90 connected with the channel section of the tilt joint, said pipe elbow having a connector end for a suction pipe,    wherein the channel section is pivoted out in the first functional position, so that an axis of rotation of a connection between the pipe elbow and the channel section is oriented at a downward slant, and wherein the channel section, in the second functional position, is pivoted into the channel connector piece so far that the axis of rotation of the connection is oriented horizontally.    
   
   
       2 . A floor nozzle according to  claim 1 , wherein a pivot range of the movable channel section is delimited by stops, and wherein a stop is assigned to the second functional position.  
   
   
       3 . A floor nozzle according to  claim 1 , wherein a joint axis of the tilt joint is disposed in a region between the two broad sides of the suction head, at a distance from the broad side that lies in the rear, in a vacuuming direction.  
   
   
       4 . A floor nozzle according to  claim 1 , wherein the suction head has an indentation that forms a free space for movement of the pipe elbow that is connected to the channel section, said indentation being disposed in a broad side of the suction head that lies in the rear, in a vacuuming direction.  
   
   
       5 . A floor nozzle according to  claim 4 , wherein a joint axis of the tilt joint is disposed within the indentation, in a region of the suction head that lies close to the floor.  
   
   
       6 . A floor nozzle according to  claim 1 , wherein the suction head has an upper housing part and an insert connected with the upper housing part, and wherein the channel connector piece of the tilt joint consists of two parts, one part being molded onto the upper housing part, and the other part being molded onto the insert.  
   
   
       7 . A floor nozzle according to  claim 6 , wherein an outer surface of the channel connector piece is molded onto the upper housing part, and the insert has a molded piece that forms a section of an inside contour that is adapted to a geometry of the channel section.  
   
   
       8 . A floor nozzle according to  claim 1 , further comprising a slide sole disposed on an underside of the suction head, said slide sole having a suction mouth that extends all the way to the narrow sides of the suction head, wherein the suction mouth is connected with the channel connector piece, in terms of flow, by an opening.
