    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.

  • Patent number: 6385811
    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.

  • Publication number: 20010042282
    Abstract: Universal nozzle to be used in connection with general known vacuum cleaners and the like, with or without washing devices, to clean floors with different floorings, including carpets, textiles and the like. The nozzle is provided with one or more cylindrical rollers, (FIG. 1 and FIG. 2), so suspended and so designed, by means of free wheeling bearings, so the rollers freely can revolve around their own axis, when the nozzle (14) is moved in one direction, but where the rollers are blocked, when moved in the opposite direction. Hair, thread and other foreign materials are thereby assembled in an oblong cylindrical cushion, easy to evacuate. The rollers can be provided with outside linings of different kind, for instance as a rubber roller, (FIG. 1), or as a brush roller, (FIG. 2). The rollers can be suspended in an activation device (7) and (10), making it possible to activate one or more of the rollers.

  • Patent number: 6029311
    Abstract: A vacuum assisted broom for sweeping floors having a sweeping member, preferably in the form of a plurality of stiff bristles, for bi-directional sweeping of the floor. The sweeping member is operatively mounted within a housing member, which housing member partially encloses the sweeping member within its hollow interior such that the bristles depend from the housing member through a first opening. A handle member is securely attached to the housing member and extends upwardly therefrom. The sweeping member has bristles which are extended such that the broom may be used as a conventional broom, and as a vacuum pick-up. An electrical switch is actuated so as to turn on a suction means that is operatively connected to the interior of the housing member, thus to create a partial vacuum, at the first opening of the housing member.

  • Patent number: 6009594
    Abstract: In a cleaning head (10) of the kind having agitating means (26) engageable with a surface to be cleaned for agitating cleaning liquid thereon, and collecting means (25) for collection of liquid from the surface by suction, the agitating means (26) and collection means (25) are relatively movable such that one or the other is selectively prominently engaged with the surface being cleaned. In a preferred arrangement the agitating means (26) is movable relative to a housing (11) of the cleaning head while the collecting means (25) is fixed in position relative to the housing (11). Cleaning liquid is delivered to the agitating means through a passage (45) which is closed by a pad (70) at the upper side of the agitating means (26) when the latter is in its raised position. Movement of the agitating means (26) between its raised and lowered positions is controlled by means of a foot pedal (65).

  • Patent number: 5625920
    Abstract: A cleaning tool is disclosed that includes a brush unit having bristles that is positionable in each of a selected one of a cleaning position and a storage position. In the cleaning position, the brush bristles contact the surface being cleaned using the tool. In the storage position, the brush bristles face in a different direction from the cleaning position and do not contact any surface being cleaned. The tool includes an attachment member for receiving the brush unit. In order to change the position of the brush unit, it is removed from remaining parts of the tool and rotated or otherwise changed in position before re-joining it to the attachment member. In changing between cleaning and storage positions, the ends of the brush unit are disposed at opposite ends of the attachment member. Preferably, the cleaning tool includes a spray control assembly for controlling the spraying of a liquid cleaner during use of the cleaning tool.
