Definitions

  • the invention relates to a thread collector of a vacuum cleaner or a suction brush for devices for cleaning carpets, textile coverings, upholstery and other cladding surfaces made of fibrous materials, which thread collector has a flat, preferably metallic plate, which is connected to an elastic part, the working surface of which is at least some parallel combs with highly elastic teeth.
  • a thread collector with teeth inclined obliquely in the direction of the suction opening of the suction device is also known (US Pat. No. 3,744,082).
  • the above-mentioned thread collectors have the disadvantage, however, that when cleaning the carpets, coverings, upholstery or other cladding surfaces, the dust penetrates into the suction brush or between the teeth and settles there, which means that the collector must be cleaned frequently.
  • the invention is therefore based on the object to provide a thread collector of the type mentioned, in which this disadvantage of frequent cleaning is avoided.
  • the plate is resilient and melted into the thread collector, which is made of a material made of thermoplastic or chemically curable elastomers with a hardness of 60 to 95 ° Sh, with the teeth are inclined at an acute angle in the direction of the suction opening of the suction device. This acute angle should preferably be 50 to 70 °.
  • the elastic teeth expediently have the shape of needles with an apex angle of 10 to 12 °.
  • the outer working surfaces of the thread collector have at least some parallel combs with highly elastic teeth, which are inclined at an acute angle in the direction of a protective edge of the thread collector, which can be arranged on its side facing the suction opening. This protective edge should not exceed the height of the teeth.
  • the arrangement of the combs is the same or offset by 1/2 or 1/3 of the tooth pitch.
  • the protruding protective edge serves for the correct use of the thread collector in the suction plate of the cleaning device.
  • the inventive design of the thread collector and in particular the arrangement of the teeth at an acute angle in the direction of the suction opening of the suction device, i.e. in the direction of its working movement, ensures effective collection of threads and hair when the thread collector is moved in the direction of the tooth inclination, and self-cleaning when moving back.
  • This advantageous effect is further enhanced by the preferred design of the teeth in the form of needles with an apex angle of 10 to 12 °.
  • the thread collector 2 has a flat, spring-rigid, preferably metallic plate 1, which is cast into the collector, which consists of a material made of thermoplastic or chemically curable elastomers.
  • the arrangement of the teeth 4 to each other can be the same or offset by 1/2 or 1/3 of the pitch of the comb teeth.
  • the teeth 4 have the shape of conical needles with an apex angle ⁇ of 10 ° to 12 °.
  • the thread collector 2 has projections 6 at its ends and its drainage edge 7 has an acute angle with respect to the support surface of the collector, on which the projection 8 is arranged at one end, which ensures the correct position of the thread collector in the snap-in openings 10 of the suction plate 9 in this way , in which the protective edge 5 lies on the longer edge of the suction opening 11 of the suction plate.
  • the thread collector according to the invention can be arranged on one or on both sides of the suction opening of the suction device or the suction brush.
