  • Patent number: 7055201
    Abstract: The invention relates to a surface treating machine which comprises a frame (1) and an undercarriage (2, 3) to enable the machine to move over a surface (S). A head (5) is supported by the frame and includes a drive motor (13) and a tool (6) for directly contacting, scrubbing or treating said surface (S). The tool is rotatably drivable by means of the motor. Cardanic drive and coupling means (16) is connected to the tool (6) in a rotationally fixed manner on one end and connected to the drive motor (13) on the other end. Support and spring means (8, 9, 17) for the tool (6), are forcing the tool (6) against the surface (S) with an controlled uneven pressure distribution around the circumference of the tool (6).

  • Patent number: 7003841
    Abstract: The invention relates to a surface treating machine, comprising: a frame (1) and a chassis (2, 3) to enable the machine to move over a surface (S) such as a floor. A head (5) is supported by the frame and comprises means (6) for directly contacting, scrubbing or maintaining said surface. The head (5) is freely movable up and down with respect to the chassis (2, 3) and is loaded downwardly by a pressure to adapt to the level of the surface. At least a part of the pressure on the head (5) is derived from the weight of the machine itself. Preferably, the head (5) is connected to a first lever arm (8) of a two armed lever (7) A second arm (9) of the lever (7) is connected to the chassis (2, 3), whereas a pivoting point (10) of the lever (7) is fixed to the frame (1) of the machine. In this way, the pressure on the head is not only provided by the weight of the machine, but the head is also easily adapting to ramps and descents in the surfaces, while the pressure on the head is maintained.
