Abstract: A brush attachment for vacuum cleaners comprises a housing consisting of a bottom part and a top part, a turbine wheel driven by the suction air stream, a brush roller driven by the turbine wheel, and a suction tube connection constructed in the form of a swivel/tilting joint. The brush roller is disposed in a brush roller chamber which has a bottom opening constructed as a suction orifice. The turbine wheel is disposed in a turbine chamber with a connection duct of the swivel/tilting joint. The duct is pivotable about the turbine wheel. The bottom part of the housing has webs which form the back wall of the brush roller chamber and the side walls of the turbine chamber and define a flow chamber. A nozzle made as a separate part is inserted in the flow chamber and contains an incident flow duct for alignment of the suction air stream flowing against the turbine wheel. The top part of the housing has connection webs which bear against the webs and against the top of the nozzle.

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: The invention relates to a vacuum cleaner nozzle with a top part of the housing and a bottom plate. The bottom plate has a suction mouth that is realized in the form of a channel extending transversely in relation to the direction of movement. Thread lifting strips made of textile material are arranged on both sides of the suction mouth in recesses in the bottom plate. According to the invention, the ratio of the nozzle width (B) measured at the ends of the suction mouth, to the length (L) of the thread lifting strips is lower than 2.8.

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: An electrical-connector shell is made by first casting of a first plastic in a first mold a body having an inner wall extending parallel to an axis and having a radially outwardly directed surface, an outer wall extending parallel to the axis and having a radially inwardly directed surface confronting the radially outwardly directed surface and forming therewith an axially extending annular space, and an end wall closing an end of the space, joining ends of the inner and outer walls, and formed with an axially throughgoing hole opening adjacent one of the surfaces. Then this body is enclosed in a second mold formed with an annular cavity open radially toward the one surface and extending to the hole. A second plastic is then injected through the hole into the cavity to form on the one surface an annular seal ring.
