  • Patent number: 6427285
    Abstract: A floor scrubber (10) is disclosed including a drive lug (62) for removably connecting a scrubbing member (64) to a drive (60) and having a trough for receipt and catching of solution for passage to the surface. The mount (58) for the drive (60) is biased by a spring (67) to pivot relative to a linkage plate (46) in turn pivotably mounted to the chassis (12) at an acute angle to the forward movement direction. The vacuum assembly (92) is sandwiched in a socket (100) formed in the bottom wall of a recovery tank (90) by a mount (106) to deaden the sound generated thereby and to allow air communication is inside of the socket (100) but generally preventing entry of solution therein. The squeegee assembly (152) is biased by a gas spring (150) to engage the surface at a constant force independent of the pivotal position of the squeegee mount (148).

  • Patent number: 6381802
    Abstract: A brush assembly for a vacuum cleaner includes a brush cover; a brush base connected to the brush cover, a rotary drum disposed between the brush cover and the brush base, and an edge brush integrated bumper. The edge brush integrated bumper is mounted around a joint surface between the brush cover and the brush base. The edge brush integrated bumper includes a pair of edge brush portions integrally formed with the bumper. Each edge brush portion corresponds to a side of the brush cover and brushes off dust that is not accessible to the rotary drum. The brush assembly further includes assembling position guide means and fixing means for securing bumper to the brush cover. Since the bumper and edge brushes are integrally formed in an injection molding process, the number of separate parts to the brush assembly is reduced. Also, since the bumper and edge brushes can be assembled simultaneously, productivity is increased as assembly time is decreased.

  • Publication number: 20020050021
    Abstract: A suction port assembly of a vacuum cleaner. The suction port assembly has a pair of suction paths formed at a front and a rear portions of a bottom of a suction port body, respectively, so as to enhance the cleaning efficiency, and due to a presence of an elastic member formed at a front edge of the suction port body as shock-buffering means, the reduction of the durability incurred by the collision with an external obstacle is prevented. Meanwhile, in case that a floorcloth is rotatably disposed on a lower surface of the bottom of the suction port body, since the suction port assembly further includes a floorcloth cover protruding from the bottom of the suction port body toward a cleaning surface, the safety of a user is guaranteed.

  • Patent number: 6256833
    Abstract: An upright vacuum cleaner includes a handle pivotally mounted to a base module, a lower portion of the handle mounts a lamp assembly which is hidden from view by the base module when the handle is in an upright, storage position and is visible above the base module when the handle is rotated to a use position. Between the front and back of the base module, a set of wheels or other projections that support the base module are mounted. The handle likewise has at a lower portion a set of wheels that mobilize the vacuum cleaner. In one embodiment, the pivot axis of the handle with respect to the base is selected so that rotation of the handle assembly from a use position to a storage position pivots a front end of the base module about the base wheels and thereby raises an agitation brush from contact with a surface to be cleaned.

  • Patent number: 6154921
    Abstract: This invention relates to a vacuum cleaner having a vacuum cleaner housing and a pivotable handle with a grip portion. The handle is pivotably secured to the vacuum cleaner housing in such a manner that the turning axis of the handle is generally horizontal and perpendicular to the direction of movement of the vacuum cleaner when the vacuum cleaner is in a working position on a horizontal surface. The handle is maintained in a generally vertical position when the vacuum cleaner is in the working position. When an operator lifts the vacuum cleaner housing from the working position using the handle, the vacuum cleaner housing pivots to a substantially vertical position, with the position of the grip portion relative to the operator's hand remaining substantially unchanged during the lifting.
