  • Patent number: 5353471
    Abstract: The invention relates to an apparatus for performing work on a floor surface such as an electrically driven vacuum and polishing machine. The machine includes a chassis and a wand pivotally connected to the chassis by a pivot connection. A vacuum cleaner suction unit is mounted on the wand and the weight force of the suction unit acts outside of the center of gravity conjointly defined by the chassis and the floor working device mounted on the chassis. The floor working device acts on the floor surface with an uneven force distribution. A spring coacts with the pivot connection to shift at least a portion of the weight force of the suction unit to the center of gravity of both the chassis and the floor working device to provide a more even distribution of the force acting on the floor surface.

  • Patent number: 5221303
    Abstract: The invention relates to an electric vacuum cleaner having a filter bag intermediate carrier disposed between a filter cassette arranged above a motor-driven blower and the motor housing. The intermediate carrier is pivotally mounted via a hinge and has guide cams which dip into engaging recesses of a base plate of the filter bag. The vacuum cleaner apparatus can only be operated with filter bags which are specific to this apparatus. Safety cams are formed on the intermediate carrier and follow the inner wall surface of the filter cassette when the intermediate carrier is closed. Catches are formed on the inner wall surface but do not catch the safety cams if an authorized filter bag is placed in the filter cassette. However, if an unauthorized filter bag is placed in the filter cassette, then the structure of this filter bag causes the safety cams to deflect and catch in the catches thereby preventing the operator from completely closing the intermediate carrier on the filter cassette.

  • Patent number: 5040263
    Abstract: The invention relates to a carrying belt arrangement for a vacuum cleaner. The carrying belt is integrated directly into a hand grip at the end of the vacuum cleaner hose. The carrying belt arrangement of the invention defines a storage compartment in which the carrying belt is wound while at the same time defining a hand grip. The carrying belt arrangement includes first and second parts of which the first part is stationary. The second part is rotatably mounted on the first part and includes the drum on which the carrying belt is wound. The first part includes a cover which extends over the drum and includes a slot through which the carrying belt passes. The drum and cover conjointly define the storage compartment for the carrying belt.

  • Patent number: 4989295
    Abstract: The invention is directed to a telescopic guide wand for floor-cleaning apparatus such as household vacuum cleaners. The guide wand includes two concentrically arranged tubes which telescopically engage each other and conjointly define an inner space to accommodate the electrical supply cable for the motor blower head of the vacuum cleaner. The tubes are latched with respect to each other in several steps and the supply cable extends as helically configured cable within the upper portion of the wand. The supply cord extends concentrically out of the end of the upper tube which is configured as a handle and can be connected to the house electrical supply system. The end of the guide wand facing toward the apparatus has a connecting device disposed thereon.

  • Patent number: 4785492
    Abstract: The invention is directed to a floor cleaning apparatus which includes a nozzle-like structure for a vacuum cleaner. The apparatus is for vacuum cleaning and polishing hard floors and is moved by the operator in a desired direction. The apparatus includes a chassis defining a longitudinal axis and at least two working plates for working on the surface of the hard floor. The working plates are movably mounted on the chassis so as to perform respective reciprocal movements counter to each other and in a direction ninety degrees to the desired direction in which the apparatus is moved by the operator. The plates conjointly define a total depth extending in the direction of the longitudinal axis of the chassis and work plate takes up one-third of this depth. The other one of the work plates takes up two-thirds of this depth. The work plates have a flat shape and at least one of the work plates is pervious to air.
