  • Vacuum cleaner nozzles of the type in question here are common executed in several parts.
  • the nozzle body itself is included regularly designed as a plastic housing and serves alongside its function as a flow-through component as a carrier for everyone Functional units of the nozzle.
  • the nozzle housing is after below, i.e. towards the floor to be sucked by a Sliding sole made of sheet steel completed in the Flow channels for optimal suction and optimal dirt particle transport are molded.
  • the flow channels are protruding through bulges Vacuum tear-off edges for optimal dust absorption surround.
  • a bristle carrier plate arranged, which means in the housing stored and arranged treads in different Switched positions for different floor coverings can be.
  • the vacuum cleaner nozzle has a nozzle body and a bottom plate that closes the nozzle body downward on.
  • the base plate serves as a sliding plate, the
  • sliding plate in the sense of the present invention also includes a design in which the plate for better guidance with rolling elements, in particular rollers or Wheels, is provided.
  • the nozzle body and the base plate as a one-piece carrier executed.
  • a carrier preferably consists of Plastic and is especially by injection molding or Molding presses made.
  • the base plate In the base plate and thus in the one-piece support the central suction channel and at least one flow channel for Distribution of suction power and for better removal of the Dirt particles immediately during the manufacture of the carrier molded.
  • the flow channel is down, i.e. to the floor open to suction.
  • the flow channel opens into the suction channel, which in turn has a suction pipe connection piece is connected to flow.
  • Sealing or closing elements on the one hand for retention a more or less precisely defined distance of the base plate from the floor to be sucked and at least to the other partially sealing boundary of the floor area to be vacuumed serve, directly molded and / or pressed, injected or glued in.
  • These sealing elements can preferably be used in the manufacture of the carrier before filling the Injection mold placed in this and when filling the mold be encapsulated.
  • the essential functional units such as Flow channel, suction channel and surrounding the flow channel Sealing and closing elements an integral part of the Are the number of separate components reduced, which reduces the manufacturing costs and in particular the assembly effort in a cost-effective manner reduced.
  • Flow channels essentially parallel to the front and / or Arranged rear edge of the carrier or the base plate and axially outwards, based on the longitudinal axis of the Flow channels, open.
  • the length of the channels should be distributed as evenly as possible Flow channels are preferably double parabolic, i.e.
  • parabolic both in cross section and in longitudinal section, based on the longitudinal axis of the flow channels, parabolic, with a parabolic profile open at the bottom with two parabolic branches is formed while extending in longitudinal section a cutting profile parabolically narrowing away from the suction channel results, with only a parabolic load, which is essentially the Corresponds to the flow channels, is present.
  • the vacuum cleaner nozzle of the invention can be found in known as a pure sliding nozzle, i.e. without roller elements, be trained. But especially if the Carrier and thus the base plate is made of plastic, the the disadvantage of a higher version compared to a metal version Has the susceptibility to wear, is the vacuum cleaner nozzle in the Area of the base plate with at least two front rollers provided in the flow channel in the area of the axial outer ends are arranged so that they flow channels essentially complete to the outside. Each is preferably the rollers on two elastically deformable steering knuckles in the Flow channel stored, each of these knuckles either integrally formed in the bottom of the flow channel or attached there, especially in the manner of a snap connection is locked.
  • the steering knuckle dodge these sideways when for example, the user of the vacuum cleaner nozzle from above accidentally steps on the wearer.
  • the danger of one Breakage and thus damage to the roll holder thereby significantly reduced.
  • the diameter of the rollers at least slightly greater than the depth of the flow channels in this area chosen. This results in an elastic deformation or an elastic lateral deflection of the steering knuckle in the event of an unintended load, a positive and non-positive connection directly between the bottom of the flow channels and thus the Carrier, the rollers and the floor, also under this Loading the base plate and thus the particularly sensitive Edges of the flow channels a sufficient safety distance retained from the ground, causing damage the edges are reliably prevented.
  • the front and / or rear edges are preferably the Flow channels related to a direction transverse to their Longitudinal axis, at least in some areas as suction or flow separation edges trained to increase the suction power of the nozzle increase.
  • These suction or flow separation edges can for example, be formed by the edges themselves Jump out from the level of the base plate in a bead shape.
  • the flow separation edges are preferred formed that the surface area in front of the front flow channel edge and / or the area behind the rear Flow channel edge at least slightly compared to the Horizontal or the plane of the base plate is inclined, wherein the inclination is chosen so that the flow channel edge receives at least slightly wedge-shaped profile.
  • the vacuum cleaner nozzle To improve the cleaning properties of the vacuum cleaner nozzle according to the invention are in a manner known per se strip or ribbon-shaped thread lifters on the base plate arranged immediately before and / or behind the suction channel. These thread lifters are used either in the manufacture of the Directly molded into the carrier, in particular injected, or provided on the carrier or in appropriate Recesses of the carrier glued, pressed or welded.
  • the vacuum cleaner nozzle according to the invention has for connecting the Suction pipe of a vacuum cleaner a suction pipe connection piece on.
  • This intake manifold connection piece can also integrally formed on the carrier in the area of the suction channel be, which results in a further reduction in parts results.
  • the intake manifold connecting piece is preferred designed as an articulated socket with its first end on Exit of the suction channel and with its second end on the suction pipe attachable to a vacuum cleaner, especially in the manner of a Snap connection is releasably lockable.
  • At least one rear roller can be arranged on the carrier.
  • This rear roller can be the only roller or in conjunction with the front casters described above Find use.
  • Fig. 1 is an embodiment in perspective view shown a vacuum cleaner nozzle according to the invention.
  • the vacuum cleaner nozzle has a nozzle body 1 to which a base plate 2 is formed in one piece, as a result, overall an integral support is formed. Molded into the carrier are flow channels 3 and 4 and a suction channel 5.
  • the suction channel is essentially central, based on the Width of the nozzle, arranged and opens on the one hand in the Flow channels 3 and 4 and on the other hand in an intake manifold connection piece 6, which is designed as a joint socket.
  • the intake manifold connection piece consists of a nozzle-side Hinge part 7, which is designed in a corresponding manner to the suction channel 5 leading opening of the carrier articulated so locked is that the joint part 7 is pivotable about the axis 8, and a joint part 9 on the intake manifold side which is connected to the joint part 7 is pivoted.
  • FIG. 2 the vacuum cleaner nozzle according to FIG. 1 is in view of shown below. It can be seen from the illustration that the flow channels 3 and 4 substantially parallel to Front or rear edge of the base plate, i.e. perpendicular to Cutting line A-A run.
  • the flow channels are 3 and 4 designed to be axially open to the outside axially outermost region one front roller 11 each is. Both flow channels open in the axially inner region into the suction channel 5.
  • Each roller 11 is on two steering knuckles 12 stored in the corresponding recesses in Because of the flow channels 3 and 4 are engaged.
  • the steering knuckle 12 are made of an elastically compliant Material.
  • the diameter i.e.
  • the rollers 11 is at least slight chosen greater than the depth of the flow channels 3 and 4 in this area.
  • sealing or closing elements in shape arranged by elastomer sealing lips 13 and 14.
  • the sealing lips 13, 14 extend essentially over the whole Width of the vacuum cleaner nozzle and close between them Distance the flow channels 3 and 4.
  • the sealing lips are as separately prefabricated sealing strips in corresponding groove-like Recesses 15 and 16 of the base plate 2 inserted and there attached by ultrasonic welding or gluing.
  • a thread lifter strip 17 and 18 arranged in the bottom area of the base plate 2 in front of and behind the Opening of the suction channel 5 .
