  • the pressing brush holders 40 are arranged in the region between the supporting brush holders 50.
  • This is particularly advantageous for small-scale uneven floors, since a uniform cleaning performance of the floor cleaning device 1 can be achieved at all points of the substrate 2 by all brushes 5 of the brush holder 20 fit snugly on the substrate 2.
  • the pressing force can be adjusted accordingly.
  • the supporting brush holder pivot axes 51 of the support brush holder 50 and the pressing brush holder pivot axes 41 of the pressing brush holder 40 are aligned parallel to each other and orthogonal to the direction of travel 3.
  • the pressing-brush holder pivot axes 41 and the support brush holder pivot axes 51 each juxtaposed pressing-brush holder 40 and / or support brush holder 50 are arranged offset in the embodiment with respect to the direction of travel 3 to each other.
  • the juxtaposed pressing brush holder 40 and / or supporting brush holder 50 are arranged overlapping with respect to the direction of travel 3. This makes it possible to nest the brushes 5, which are juxtaposed with respect to one direction orthogonal to the direction of travel 3, and thus overlap the areas swept by the brushes 5 when the brush device 20 moves in the direction of travel 3.
  • Each of the brushes 5 is individually rotatable in the exemplary embodiment by means of a respective motor 36 about a vertical axis of rotation. This is an individual driving the brush 5, z. B. possible with different rotational speeds or in different directions. By the opposite direction of rotation, for example, based on the direction of travel 3 consecutively arranged brushes 5, the cleaning performance can be further increased. It is also conceivable and possible, for example, for the two brushes 5 mounted on a pressing brush holder 40 or on the supporting brush holder 50 to be driven by a common motor 36 and a corresponding distributor gear.
  • Fig. 11 to 13 illustrated second embodiment of a floor cleaning device 1 according to the invention differs from the first embodiment in terms of the type of suspension of the brush device 20 on the suspension unit 10 and the initiation of the thrust forces to move the brush device. Apart from the still to be explained below Differences from the first embodiment corresponds to the embodiment of that of the first embodiment and reference is made to the description of the figures for the first embodiment.
  • the axle unit 22 is movable in the second embodiment both in the vertical and in the horizontal direction relative to the suspension unit 10.
  • the guide pins 23 pass through a window recess 17 of the suspension unit 10, cf. Fig. 11 to 13 ,
  • the push members 11 of the suspension unit 10 are formed here as separate parts and act in the working position, the brush device 20 for movement in the direction of travel 3 directed against the direction of travel 3 surfaces 26 of the brush device 20.
  • the thrust members 11 are disposed below the height of the pivot axis 13. In contrast to the first embodiment, the suspension unit 10 thus does not interact with the axle unit 22 to transmit the thrust.
  • the thrust members 11 are conveniently adjustable in height relative to the thrust member 11 supporting part of the suspension unit 10. This is not shown separately in the figures. In particular, due to the different soil conditions or friction coefficients of the substrate 2 and the frictional forces acting thereby can be equalized by a height adjustment, the torque acting through the friction about the pivot axis 13. By a corresponding arrangement of the thrust member 11 at a certain height, depending on the friction conditions occurring a corresponding counter-torque can be adjusted. In this case, the force member 14 can be conveniently unlocked, d. H. that in the working position no additional torque from the lifting unit 10 to the axle unit 22 about the pivot axis 13 must be exercised. However, it is also conceivable and possible, even in the second embodiment, to use the lifting unit 14 for exerting a torque about the pivot axis 13.
  • both guide pins 23 are on a window recess 17 upwardly bounding wall, see. Fig. 13 .
  • the Force member 12 may in this case, in contrast to the working position, be controlled so that it moves into a retracted position and the axle unit 22 holds above.
  • the guide pin 23 in the working position of the brush device 20, which occupies this when cleaning a horizontal surface 2, seen in the vertical direction is arranged centrally between the limiting walls of the recess 17 of the suspension unit 10.
  • the thrust member 11 allows in the second embodiment, an adjustment of the position of the brush device 20 relative to the vehicle 4 seen in the direction of travel 3, by the variation of the length of the thrust member 11, which is shown in the embodiment as an adjusting screw.
  • the lifting member 14 is supported at a different location on the vehicle than on the suspension unit 10.
  • the force member 12 is supported at a different point of the vehicle on the vehicle. It is of course conceivable and possible for the lifting member 14 and the force member 12 to be supported on the suspension unit 10 analogously to the first exemplary embodiment.
  • the drawn in the figures direction 3 refers to a straight ahead of the vehicle 4. Other directions, eg when driving on bends are possible. Also, a reverse drive against the marked direction of travel 3 is conveniently at least at a slow pace possible, possibly with reduced cleaning performance.
  • the thrust force in a reverse drive in the region of the axle unit 22 must be initiated.
