    Abstract: A vacuum cleaner nozzle has a housing with a plastic upper part, a slide sole and a gasket base pivotably arranged around an axis in the upper part of the housing. There is at least one strip-shaped gasket element that can be retracted and moved out with an adjusting movement of the gasket base at the lower side of the nozzle. The slide sole is fastened to the upper part of the housing with slip joints between pivot-shaped projections on the upper part and counter-elements formed on the slide sole. The gasket base is guided on at least one of the pivots formed by slip joints.

  • Publication number: 20040231095
    Abstract: A cleaner includes a suction motor mounted in a cleaner main body, and generating a suction force; a filter for collecting dust or filth sucked by the suction force generated at the suction motor; a suction head connected with the filter by a suction tube, and sucking dust and filth on a floor; a brush installed in the suction head so as to ascend/descend in a vertical direction, and sweeping dust and foreign substances into the suction head; and a brush height control apparatus installed in the suction head, and making the brush ascend/descend in a vertical direction. The cleaner having a brush height control apparatus can prevent deterioration of a suction force and improving cleaning performance by constantly maintaining a gap between the suction head and the floor.

  • Patent number: 6802098
    Abstract: The present invention provides an adjustment mechanism and methods for adjusting the alignment of a powered cylindrical brush mounted to a surface maintenance vehicle relative to a surface to be maintained or cleaned by the vehicle. The device is preferably disposed upon the idler-side of a powered rotating cylindrical brush assembly and the adjustment preferably occurs via use of an eccentric cam member providing a range or motion, or pivot location, through or about which the idler-side mounting location of the cylindrical brush may be adjusted to improve contact with the surface. The present invention enables such adjustment without decoupling the rotating brush from its couplings (both supportive and rotational coupling), and any coupling to a drive mechanism for driving the rotating brush into rotation. The rotating brush so adjusted will benefit from improved mechanical cooperation between the bristles of the brush and the surface to be cleaned.

  • Patent number: 6775881
    Abstract: A blower head, comprising a frame, a brush rotatably supported by the frame, a sweeper drive adapted for rotating said brush to sweep a surface, and a blower unit adapted for removing swept-up particles away from the surface. The frame includes a mouth portion and a throat portion. The brush is rotatably supported by the frame within the mouth portion. The sweeper drive rotates the brush to sweep particles such as snow or ice on a surface toward the frame. The mouth portion and the throat portion are constructed and arranged to funnel swept-up particles from the mouth portion and into the throat portion and the blower unit positioned therein. The blower head further includes an exit chute. The blower unit creates a pressure differential between the mouth portion and the exit chute sufficient to draw the swept-up particles from the mouth portion and into the throat portion, and to blow the swept-up particles out through the exit chute.

  • Patent number: 6618897
    Abstract: The control apparatus and vehicle of the invention for controlling a broom and blower system attached to the vehicle typically includes several modules (which may be software, hardware, or a combination of these) which interact to process command inputs. Thus, broom state, broom height, and broom direction command modules are all logically connected to a command input module. Similarly, blower state (blower on/off) and direction (blower left/right) modules are also logically connected to the command input module. The method of the invention for operating a broom and a blower includes the steps of receiving a command input, measuring the duration of the command input, and determining whether the command input is a broom state command, a broom height command, a broom direction command, a blower state command, or a blower direction command. If the command is one which requires selection of an intermediate position, then the command is followed as long as the command is entered.

  • Patent number: 6134745
    Abstract: A vacuum cleaning tool, especially a suction nozzle for the floor, is provided. The tool includes a housing having a suction chamber that is connected to a vacuum cleaning unit by a connector. Disposed in the suction chamber is a brush roller, the bristles of which extend through a suction opening. The brush roller is rotatably disposed in the housing between lateral mounting pieces, which are held by respective pivot arms in such a way on a pivot element provided in the housing that the brush roller can be pivoted out of the suction chamber about a pivot axis that is disposed approximately parallel to the brush roller. One of the pivot arms is detachably connected with the pivot element via a plug connection, which is provided with electrical plug contacts via which the electrical line of an electric drive motor disposed in the brush roller can be connected with an external power source.

  • Patent number: 6081963
    Abstract: A vacuum cleaner is provided with a wheel housing having at least one axle bracket extending therefrom along a transverse axis and at least one axle bracket-receiving socket formed in a foot of the vacuum cleaner whereby the socket slidably receives and pivotally mounts the at least one axle bracket. The wheel housing is thereby pivotally mounted to the foot. A height adjustment mechanism is provided with the wheel housing having an actuator having a bearing shaft and a bearing sleeve with a longitudinal bore. The longitudinal bore of the bearing sleeve receives the bearing shaft to rotatably mount the actuator. A detent mechanism is provided between the bearing shaft and the bearing sleeve to releasably mount the actuator to the foot. The actuator can be adapted to release upon encountering abnormal forces applied against the vacuum cleaner.

  • Patent number: 6076230
    Abstract: A height adjustment mechanism for a vacuum cleaner includes a wheel carriage pivotally mounted to a foot of the vacuum cleaner, a height adjustment cam which engages the wheel carriage, and a cam actuator which attaches to the height adjustment cam for camming the height adjustment cam against the wheel carriage. The height adjustment cam is formed with a stepped bottom camming surface. The camming surface is formed with a plurality of spaced parallel ribs having a rounded outer surface which minimizes the surface-to-surface contact between the height adjustment cam and the wheel carriage. This reduced surface-to-surface contact reduces the frictional resistance between the height adjustment cam and the wheel carriage allowing the cam actuator to be easily slid for height adjustment of the vacuum cleaner foot.
