Definitions

  • the invention relates to a washing brush for car washes with a rotatable shaft on which side by side and plate-shaped cleaning elements at a distance from one another made of a flexible material perpendicular to the axis of rotation of the Shaft and rotatably connected to this are kept.
  • Such a washing brush is for example from the G 93 09 920 U1 known.
  • the cleaning elements are circular in cross section, and it has been found that cleaning elements of this kind have a tendency to permanently kill on the edge, if the washing brush is against a surface to be cleaned drives up. As a result, between adjacent cleaning elements, which are in opposite directions folded, uncleaned strips remain.
  • it has also proven to be disadvantageous that when moving the known washing brush to a cleaning one Surface almost no braking of the washing brush, that means there is only a very small braking torque on.
  • Such braking is usually used in car washes to determine the immersion depth of the Regulate the washing brush, i.e. the distance of the washing brush of the surface to be cleaned. This is the case with the known ones Wash brushes of this design are only very limited possible.
  • the axis of rotation is the cleaning elements in the Enforce area focus, but it is a preferred one Embodiment also provided that the axis of rotation the cleaning elements deliberately outside the focal areas enforced.
  • the cleaning elements can have a wide variety of shapes have, for example, the shape of equilateral Triangles, of isosceles triangles, preferably with an aspect ratio between 1 and 3, or from Rectangles with an aspect ratio between 1 and 10.
  • the edge regions of the Cleaning elements by incisions in the edge of the cleaning elements ending stripes are divided. By this subdivision of stripes increases the cleaning effect elevated.
  • the incisions can be made in parallel in groups to each other. In particular, can be provided be that the incisions parallel to lines of symmetry of the Polygonal cross section. If the polygonal cross sections have several lines of symmetry then several groups of differently oriented incisions.
  • the width-thickness ratio of the Strip is between 2 and 20.
  • the cleaning elements with a push-through opening have a polygonal cross section for the shaft and that the shaft with a corresponding polygonal cross section Non-rotatable and positive connection with the cleaning element manufactures.
  • the cleaning elements can be made of a porous, water-permeable Material exist, for example one Foam or in particular from a nonwoven fabric.
  • Washing brush 2 shown as in conventional Car washes can be used, especially for Roof cleaning.
  • Every cleaning element 3 has a passage opening 4 through which the Shaft 1 passes vertically. Both are Shaft 1 and the passage openings 4 with each other complementary polygonal cross sections formed so that a form-locked connection between the shaft 1 and the cleaning elements 3 is obtained.
  • the rectangular cleaning elements 3 are, for example from a layer of a nonwoven or from one flexible, porous foam.
  • Neighboring cleaning elements are exemplary embodiments 3 rotated 90 ° against each other, so that the elongated rectangles each at different angular positions protrude radially.
  • Spacers are located between the individual cleaning elements 3 5 arranged, the outer dimensions are essential are smaller than the external dimensions of the cleaning elements 3rd
  • the cleaning elements 3 take the one shown in FIG Position in which they are exactly in a perpendicular to the plane of rotation defined by shaft 1 extend only when the shaft 1 is rotated, because the Cleaning elements 3 from a flexible and partially limp material exist. Stretch while turning However, the cleaning elements 3 under the effect of Centrifugal force and thereby settle down with their narrow Edges on surfaces to be cleaned. The system is created first in the corner area of the cleaning elements 3 and even only with the cleaning elements that go beyond the neighboring ones Cleaning elements in a certain angular range protrude. This cleans the surface to be cleaned from always hit different edges, so that the Cleaning elements 3 different when turning further can flip to one side or the other and ensure that no uncleaned areas remain. In addition, the impact of Edges on the surface to be cleaned a striking contact, which the cleaning effect compared to the permanent Circular cleaning element systems improved.
  • These incisions 6 are preferably parallel facing each other and continue to run parallel to each other Axes of symmetry of the polygonal cross section of the cleaning element.
  • the incisions run parallel to the long edge of the Rectangle only on one side of the rectangle and create there is a bevy of parallel strips 7.
  • the passage opening 4 is in the not through incisions 6 subdivided area and outside of the area focus.
  • a cleaning element 3 in the form of an isosceles triangle shown, in this case no strips 7 are formed.
  • FIG. 5 it can be seen how cleaning elements with the cross section of a simultaneous Triangularly offset by 180 ° on shaft 1 are held so that the washing brush has the cross-sectional shape of a six-pointed star.
