Definitions

  • the invention relates to a hand-held device for cleaning smooth surfaces, in particular glass panes, with a flat-box-shaped holder with a handle, a sponge block and a wiper strip which can be exchanged in parallel at a distance therefrom, the wiper strip edge sloping forward over a top wall of the holder, approximately in the free surface of the Sponge blocks lying, protruding.
  • Handheld devices of this type for cleaning smooth surfaces are known from EP 0 263 456 B1.
  • This hand-held device has the disadvantage that the distance between the top wall and the free front edge of the wiper strip is constant, therefore occurs when cleaning modern windows, which are usually held in a rubber or silicone frame, about 1 cm from the window extends into the frame, the problem is that when cleaning the frame-side web the wiper strip corner is held back by high friction values on the rubber and bent up, so that an approximately 1 cm wide glass edge strip remains moist and also the side of the usually slightly oblique wiper strip liquid displaced to the frame from the resulting gap increasingly flows downwards.
  • the wiper strip with its end assigned to the window frame side in the edge region is lifted off the surface of the glass pane to be cleaned due to the friction on the elastic seal
  • the solution to the problem is that the top wall of the holder in the two corner areas assigned to the wiper strip is advanced to close to the wiper strip edge, with the formation of stabilizing lugs for the wiper strip.
  • the distance between the top wall and the front wiper strip edge is therefore different over the length of the wiper strip;
  • the distance to the wiper strip edge is smaller than in the middle area in between and is still about 2 mm in order to ensure elastic adaptation to the rest of the wiper edge profile with slight pressure.
  • the stabilizing lugs are molded onto the wiper strip side corner areas of the top wall.
  • the stabilizing lugs are shaped out of the top wall, i.e. In the corner area of the top wall, the stabilizing lugs are punched out and then pre-bent into their corresponding position.
  • the side wall is formed from the stabilizing nose in the direction of the free sponge surface and flat from the disc level of a surface to be cleaned.
  • the deep-drawn side wall is particularly advantageous for wipers that are at a relatively large distance from the edge of the wiper strip to the sponge of about 5 - 6 cm, which is necessary for depositing the sponge from a deep frame with the wiper strip edge drawn up to the seal continued inside in a T-shape, so that a U-shaped receiving chamber is created behind the wiper strip for stripped liquid and foam, which concentrate there without running off.
  • the chamber walls are approximately 1 - 2 mm above the glass, depending on the pressure exerted when wiping, even closer. Since the drainage and the wiping movement are dynamic processes, the relatively wide gap is sufficient to always catch the water and the foam and to prevent them from running off.
  • the two side walls of the box-shaped housing each have a recess adjoining the front, through which the wiper strip is laterally bordered and from which it projects laterally beyond the side wall with a short side region.
  • the short lateral protrusion of the wiper strip in the side groove is advantageously held so that it does not bend significantly even when it comes into contact with an inhibiting frame sealing rubber and takes the cleaning water sealingly with it when the window pane is pulled off in the frame area.
  • the wiper strip By protruding the wiper strip from the box-shaped housing with a good hold in the slot, it is easily possible to remove the window cleanly in the corner areas. Since the wiper strip only protrudes 1 - 2 mm from the recesses in the side walls, it is kept dimensionally stable. This avoids the problem of the wiper strip ends bending up when the window's rubber surround is jammed.
  • the distance between the front edge of the top wall and the front edge of the wiper strip is advantageously greater in the central area than in the corner areas; there it is still about 2 mm, which ensures an elastic adjustment over the entire course of the wiping edge with only slight pressure. Even when the seals in the window frame come into contact laterally, the wiper strip lies completely on the glass pane, and the edge of the wiper strip is lifted off the surface of the glass pane, with the formation of gaps between the surface of the glass pane and the wiper strip.
  • the stabilizing lugs arranged in the corner area of the top wall press the wiper strip onto the glass pane surface close to its lateral ends, so that the wiper strip lies flat on the surface of the glass pane and thus the cleaning liquid or the water and foam easily, without streaking the surface is removable.
  • the elastic wiper strip is stabilized in the withdrawal direction on the back of the side wall of the holder and in the pressure direction from the back of the slot.
  • This back is preferably adapted in shape to the rear bevel of the wiper strip.
  • the bevel of the wiper strip is either continued up to the wiper edge or the wiper strip is supported perpendicular to the wiper edge, so that it protrudes in a trapezoidal shape.
  • the side sections of the wiper strip protruding from the recesses have a triangular or trapezoidal shape.
  • the supporting side wall is preferably brought almost to the edge of the wiper strip and closer to it than the stabilizing lugs by 1-2 mm.
  • the stabilizing lugs are molded onto the corner regions of the cover wall on the wiper strip side.
  • the side walls are designed to run back from the stabilizing nose in the direction of the free sponge surface from the pane level of a surface to be cleaned, that is to say with a recess.
  • the sponge can advantageously be set down from a deep frame with the wiper strip edge drawn up to the seal.
  • the deep-drawn side wall on the wiper strip side is angled approximately parallel to the wiper strip or Continued in a T-shape, so that a U-shaped receiving chamber is created behind the wiper strip for stripped liquid and foam, which concentrate there without running off.
  • the chamber walls are approximately 1 - 2 mm above the glass, depending on the pressure exerted when wiping, even closer. Since the drainage and the wiping movement are dynamic processes, the relatively wide gap of the side wall up to the surface to be cleaned is sufficient to always catch the water and the foam and prevent it from running off.
