    Abstract: A vacuum cleaner having a joint assembly to selectively rotate an extension pipe with respect to a handle. The joint assembly has a joint body removably installed between the extension pipe and the handle to allow the extension pipe 130 to rotate with respect to the handle 140 within a predetermined range. Also included on the joint assembly is a supplemental handle protruding from an outer surface of the joint body. The joint assembly and supplemental handle allow the user to clean under a bed or a desk without having to bend his/her back too much. Therefore, the user is not easily fatigued even when he/she cleans under the desk or bed.

    Abstract: Pressurized filtered exhaust air from a motorized fan in a vacuum cleaner body passes on an exhaust path to a floor suction tool. The exhaust air is directed by the floor suction tool generally parallel to the surface to be cleaned to agitate dust and thus to improve cleaning performance. An electric motor in the floor suction tool drives a rotation brush. The exhaust air is also directed toward the rotation brush in the floor suction tool in a direction to add rotation force to the rotation brush. Feeder lines to the electric motor pass through the exhaust path so that the feeder lines are exposed only to filtered air. Passing the feeder lines through the exhaust path avoids the necessity to make special provision for the feeder lines.

  • Patent number: 6185918
    Abstract: This Power air blower fan head mobilizer of matted vegetation solves the problem of blowing leaves and other debris matted together by wind or rain. A flexible serrated mobilizer probe (composed of metal, plastic, or composite) is inserted into the terminal fan head air nozzle of an air or leaf blower in such a way that a mass of often wet debris is stirred, tossed, moved, and cut. Thus, the invention opens pathways into the matted mass so that airflow is effective. The device includes a curved sharp terminus, which acts as a vegetation cutter on both flat and irregular surfaces. Large stemmed vegetation and small limbs can also be sawed in two because the probe has coarse and fine serrations on its respective lateral sides. In addition, the 5 inch projecting curved probe terminus provides a spring skid to reduce weight of the power air blower, thus saving energy of the operator.

  • Patent number: 5991972
    Abstract: A cleaning tool having a height adjustment mechanism which may be overridden to prevent damage to the cleaning tool in the event an excessively high force is applied to an exterior surface of the cleaning tool. The height adjustment mechanism forms an overrideable clutch having a manually adjustable thumbwheel, a biasing member and a clutch member. The height adjustment assembly is operably associated with a roller assembly which supports the cleaning tool on a work surface at a desired height above the work surface. The application of a predetermined excessive force to an exterior surface of the cleaning tool causes the height adjustment assembly to be de-clutched to allow the lower surface of the cleaning tool to come in contact with the work surface, thereby preventing damage to the various internal components of the cleaning tool.

  • Patent number: 5993563
    Abstract: A larger scrubbing machine and a smaller scrubbing machine are provided in combination. The larger scrubbing machine scrubs larger floor areas and the smaller scrubbing machine scrubs smaller floor areas that are typically inaccessible by the larger machine. When the larger machine is being used, the smaller scrubbing machine is attached thereto. When a smaller floor area is to be cleaned, the smaller scrubbing machine is removed from the larger scrubbing machine. The smaller scrubbing machine includes a scrubber assembly and a motor that is powered using an electrical power source located on the larger machine. A spring is operatively connected to this scrubber assembly for ensuring desired contact between the brush bristles and the floor area being cleaned. Two spaced pairs of wheels provide a uniform plane of contact during scrubbing by the scrubber assembly.

  • Patent number: 5901411
    Abstract: A suction tool for an electric vacuum cleaner includes: a suction tool body which is connected to the vacuum cleaner body and has a suction inflow passage therein for conducting a suction air stream from a suction port, to the vacuum cleaner body; and a movable brush which is provided inside the suction inflow passage formed in the suction tool body and is driven by a driver device. In this tool, the movable brush sways and reciprocates back and forth about a support shaft, perpendicular to the direction of the suction inflow stream. Alternatively, the tool may have a linear motor which operates so as to reciprocate a rod which is liked at one end of it with oscillatory plate pivoted inside the suction tool. Further, this movable brush may be formed of a unit which is composed of a sweeping member having a pair of front and rear sweeping parts and a moving brushing part embedded in between, wherein the front sweeping part is shorter than the rear sweeping part.
