Definitions

  • the invention relates to a vacuum cleaner nozzle, in which on both sides of the suction channel delimited by the edges of the mouthpiece, thread levers consisting of inclined bristle material attached to a support plate are arranged with their longitudinal axis parallel to the suction channel.
  • Such a vacuum cleaner nozzle is known from DE-PS 15 03 830.
  • the thread lifters are flat and arranged in one plane.
  • different types of carpets must be processed, namely those with a softer or harder pile.
  • different -. penetration depths of the nozzle When vacuuming a carpet with a soft pile, the thread lifters in the known nozzle lie firmly on the pile as a result of the nozzle sinking deeper into the pile.
  • the inclined bristles of the inclined bristle material are completely pressed so that they can no longer fulfill their function. It also results from the fixed There is an increased flow resistance, which impedes or completely prevents an air flow under the thread lifter.
  • the invention has for its object to design a vacuum cleaner nozzle so that the effect of the thread lifter is maintained when vacuuming different types of carpets and an increase in flow resistance at the thread lifter is largely avoided.
  • the object is achieved according to the invention in that the thread lifters in themselves or in relation to each other are set to different depths relative to the relevant mouthpiece edge. In this way it is achieved that one or the other thread lifter or parts of the thread lifter are effective when vacuuming a carpet with a firm or soft pile.
  • a different depth arrangement of the thread lifters with respect to the edge of the mouthpiece is easily achieved in that the thread lifters have support plates of different thicknesses.
  • the thread lifter is set back at different depths in relation to the edge of the mouthpiece. This means that parts of the thread lifter remain fully effective if the vacuum cleaner nozzle sinks into the carpet pile to varying degrees.
  • a curvature of the thread lifter is achieved in that the support plate for the inclined bristle material is arched or in that the thread lifter has a flat support plate which, with its two longitudinal sides, is inserted into two corresponding longitudinal slots provided on the underside of the vacuum cleaner nozzle is stuck, the distance from each other is smaller than the width of the thread lifter. In the latter case, the thread lifter is arched by inserting it into the longitudinal slots.
  • the vacuum cleaner nozzle 1 shown in FIG. 1 has a suction connection 2, which is in suction connection with a suction channel 3 provided on the underside of the vacuum cleaner nozzle 1.
  • the suction channel 3 is delimited on both sides by mouthpiece edges 4 and 5.
  • Thread lifters 6 and 7 are arranged parallel to the suction channel 3.
  • the thread lifter 6 arranged in front of the suction channel 3 in the working direction is set back by the dimension a and the thread lifter 7 arranged behind the suction channel 3 by the dimension b.
  • the dimension b is smaller than the dimension a.
  • This differently deep offset of the thread lifters 6 and 7 with respect to the mouthpiece edges 4 and 5 is achieved by supporting plates 8 and 9 of different thicknesses.
  • the support plate 9 is made thicker than the support plate 8.
  • the mouthpiece seams 4 and 5 sink only a little into the carpet pile, so that the thread lifter 7 arranged behind the suction channel 3 has a more intensive effect than the thread lifter 6 arranged in front of the suction channel 3.
  • the mouthpiece edges 4 and 5 sink deeper into the pile, as a result of which the inclined bristles of the thread lifter 7 arranged behind the suction channel 3 can be pressed onto the support plate 9, so that this thread lifter can no longer fully fulfill its function .
  • the thread lifter 6 arranged in front of the suction channel 3 has a better effect since it is set back so far relative to the mouthpiece edge 4 that its inclined bristles are not impaired in their action even when the mouthpiece edges 4 and 5 sink in deeper.
  • the thread lifters 6 and 7 are curved on their surface. This curvature means that the thread lifters 6 and 7 are set back at different depths in relation to the mouthpiece edges 4 and 5. Depending on the sinking depth of the mouthpiece edges 4 and 5 into the carpet pile, a partial area of the thread lifters 6 and 7 always remains fully effective. Due to the curved shape of the thread lifters 6 and 7, there is only a small contact surface of the thread lifters, so that the flow resistance remains very low, in particular with this shape, and an air flow under the thread lifters is therefore always possible. The curvature of the thread lifters 6 and 7 can be achieved in that - as shown in FIG.
  • an arched support plate 10 is provided, on the curvature of which the oblique bristle material 11 is fastened.
  • a flat support plate 12 and this with its long sides in Insert longitudinal slots 13, the spacing of which is smaller than the width of the support plate 12.
  • Such a geometric configuration inevitably causes the support plate 12 to be arched when it is inserted into the longitudinal slots 13.
  • sawtooth-like teeth are provided on the outer longitudinal edges of these longitudinal slots 13 and engage with their tips in the thread lifter.
