Abstract: A suction head for a vacuum cleaning devices comprising an electrically operated brush roller and a lighting system for illuminating the working field. The lighting system contains a plurality of ultra-bright light-emitting diodes.

Abstract: A vacuum-cleaner floor head has a base plate formed with an elongated mouth through which air is aspirated, a frame vertically displaceable between a lower position and an upper position, and a seal strip carried on the frame, engaging a floor underneath the head in the lower position, and clear of the floor in the upper position. The strip is elastomerically compressible, surrounds the mouth, and is sufficiently firm to support the head off the floor without substantial deformation during normal back and forth stroking of the head on the floor in the lower position of the frame. The strip has at least to a front side of the mouth a profiled lower surface formed with a plurality of alternating ridges and hollows so that in the lower position the ridges engage the floor and air can be aspirated through the hollows between the floor and the strip.

Abstract: A suction head for floor vacuum cleaners has a unitary plastic housing (1) containing a suction channel (2), and a bottom plate (7) arranged on the underside of the housing and having a suction mouth (13). The suction mouth adjoins a vertically aligned, box-shaped connection element (14) of the suction channel and feeds into a bottom channel (15) of the bottom plate (7). The bottom plate (7) is pivot-mounted both on the connection element (14) of the suction channel and also at the end side on the inner surfaces of the plastic housing (1). For this purpose, the box-shaped connection element (14) contains transverse bridges (17) that define the suction channel laterally and which have bottom edges designed as bearing surfaces (18) rounded in a curved manner. The bottom plate (7) is supported on the curved, rounded support surfaces (18) of the connection element (14), and rotatably interlocked with the wall surfaces of the connection element (14) extending parallel with the transverse bridges.

Abstract: A vacuum-cleaner nozzle has a housing forming a turbine compartment and a brush compartment and having opening into the turbine compartment an outlet adapted for connection to a fan input and a slot opening into the brush compartment. A brush rotatable in the brush compartment has bristles projecting from the slot. A turbine in the turbine compartment is oriented such that air flow from the slot to the outlet rotates the turbine. A drive or transmission couples the turbine to the brush for rotating the brush when the turbine rotates. A button is displaceable on the housing between an outer position and an inner position and a spring urges the button into the outer position. A link between the button and the drive arrests rotation of the brush on displacement of the button into the outer position. This button is remote from the slot and the housing is formed with a handle adapted to be held by a hand of a user.

Abstract: The vacuum cleaner nozzle of the present invention has a nozzle body with a suction pipe connecting piece and a bottom plate which closes off the nozzle body towards the bottom, whereby the bottom plate is provided with at least one flow channel open towards the bottom to allow air to flow into a suction channel centrally connected to the suction pipe connecting piece, said nozzle body being provided with sealing or closing elements which surrounds the flow channel at least in part. The nozzle body and the bottom plate are made in the form of a one-piece supporting base into which the flow channel or the flow channels and the suction channel are directly molded. The sealing or closing elements in the form of bristle strips and/or sealing lips are molded directly into the bottom plate and/or are pressed, injected or glued into it. This design reduces the number of components of the vacuum cleaner nozzle considerably so that a significant simplification is achieved with respect to manufacture and assembly.

Abstract: The vacuum cleaner nozzle of the invention is provided with a nozzle body equipped with a suction pipe connecting piece and with a bottom plate which closes off the nozzle body towards the bottom, whereby at least one flow channel which is open towards the bottom and lets out into a central suction channel connected to the pipe connecting piece is located in the bottom plate. The flow channel is here double-parabolic in profile, meaning that it is parabolic in its cross section as well as in its longitudinal section extending perpendicularly to the bottom plate in relation to the longitudinal axis of the flow channel. The cross-section increases in this case from the bottom of the flow channel in the direction of the floor and from the end of the flow channel away from the suction channel in the direction of said suction channel. Thanks to this configuration of the suction channel, even distribution of the suction capacity is achieved over the entire width of the vacuum cleaner nozzle.
