Definitions

  • the invention relates to a bristle strip for a vacuum cleaner nozzle according to the preamble of claim 1.
  • the invention further relates to a vacuum cleaner nozzle.
  • canister vacuum cleaners In so-called canister vacuum cleaners, the motor, blower, filter unit and electronic devices are arranged in a housing, which is usually mounted on rollers.
  • An often telescopically adjustable in length suction pipe is connected at one end by means of a flexible suction hose with the housing or the blower of the vacuum cleaner and has at its other end a floor nozzle, which comes into contact with the surface to be cleaned.
  • a second design form the so-called hand vacuum cleaner.
  • the suction pipe is rigidly connected to the vacuum cleaner housing.
  • engine, blower, electrical and filter unit are housed in the housing.
  • This additionally has on the side opposite the suction pipe connection on an extension of the suction pipe attached handle for handling.
  • the negative pressure generated by the motor and blower is transmitted to the surface to be cleaned by means of a nozzle.
  • nozzles such as floor nozzles, upholstery nozzles or the like.
  • the best possible contact with the floor nozzle is desirable in order to achieve a deep and high suction effect.
  • the direct suction is often not sufficient to release stuck dirt particles from the surface. moreover There is, depending on the design, the risk of a solid suction of the floor nozzle on the surface and thus possibly also a damage to the floor covering by scratching.
  • Nozzles in particular floor nozzles, upholstery nozzles or the like, according to the prior art are therefore usually equipped with one or more bristle strips. These are arranged so that their bristles extend from the underside of the floor nozzle, which contacts the surface to be cleaned, substantially perpendicular to the floor nozzle in the direction of the floor.
  • these bristles are by means of a foot switch on the floor nozzle via a mechanism between an extended position in which the bristles protrude from the bottom of the floor nozzle and so can come into contact with the floor covering and optionally create a distance between the nozzle and floor covering, as well as a sunk Position in which they are essentially retracted without function in the floor nozzle, switchable.
  • Prior art floor jets are typically equipped with a separate bristle bar that consists of three parts: a metal rail, an insert wire and polyamide bristles. These three elements must be assembled in several assembly and manufacturing steps to form a functional bristle strip. This assembly is time consuming and costly.
  • bristle strips are known, which are made in one piece from a material. Although these are easy to manufacture, they have to be differentiated between the different requirements. ments, which represent the bristles on the one hand and the bristle backs on the other hand, a compromise can be found.
  • the invention is based on the generic bristle strip in that the carrier element consists at least partially of a hard component and the bristles at least partially made of a soft component.
  • the choice of components with different degrees of hardness for different regions of the bristle strip represents an optimization of the same in terms of functionality.
  • the carrier element regions of PP, PP-GF or the like can be produced.
  • the bristle element areas can be made of TPE, PVC, silicone, elastomer or the like, for example.
  • the bearing areas of the bristle strip are optimized in terms of their supporting functionality, while the bristles can be sufficiently flexible.
  • the bristles are injection-molded onto the carrier element in an injection molding process.
  • the bristles can be particularly easily and inexpensively molded to the support element and so the one-piece can be achieved.
  • the bristles are substantially conical.
  • the bristle ends are rounded. This increases the service life of the bristles and thus also of the bristle strip and protects sensitive surfaces during their cleaning.
  • the bristles are arranged in a plurality of rows and / or offset from each other. This allows a sufficiently dense occupation of the carrier element with bristles with a simultaneously optimal mobility of the bristles on and against each other.
  • the invention also relates to a Staubsauger convinceddüse with a bristle strip according to the invention.
  • the advantages of the bristle strip according to the invention can also be realized in the context of a Staubsauger convinceddüse.
  • the invention is based on the finding that in a production of the bristle strip for a Staubsauger foundeddüse from at least two components with different hardness considerable installation costs can be saved and at the same time the functionality of the bristle strip can be improved.
  • the present invention can be used in all common types of vacuum cleaner.
  • Figure 1 is a perspective view of the bristle strip according to the invention.
  • FIGS. 2a, 2b and 2c are longitudinal sectional views of the bristle strip according to the invention.
  • FIG. 3 shows a cross-sectional view of the bristle strip according to the invention.
  • FIG. 1 shows a perspective view of the bristle strip 10 according to the invention.
  • the bristle strip 10 has a carrier element 12. This is made in a 2K injection molding process from a hard component such as PP or PP-GF. Forty or thirty-nine bristles 14 are molded onto the carrier element 12 in four longitudinal rows. These consist of a soft component, such as TPE, PVC, silicone or elastomer.
  • FIG. 2a, 2b and 2c show two longitudinal sectional views of the bristle strip 10 according to the invention.
  • FIG. 2a shows a longitudinal section through the bristle strip 10 along its axis A, perpendicular to the orientation of the bristles 14.
  • FIG. 2b shows a longitudinal section along the axis A of the bristle strip 10 along the orientation of the bristles 14.
  • Figure 2c shows an enlarged detail of Figure 2b, as indicated by the dash-dotted circles.
  • FIG. 3 shows a cross-sectional view of the bristle strip 10 according to the invention.
  • the sectional view extends perpendicular to the axis A of the bristle strip 10.
  • the support member 12 is made of a rigid material and can thus absorb and pass on the forces that occur during an extension or retraction of the bristle strip on the underside of the Staubsauger foundeddüse.
  • flexibility of the bristles 14 can be achieved by the soft component. Due to the conical or cone-shaped configuration of the bristles 14, a sufficiently large transition region between bristles 14 and carrier element 12 is provided. The ends 16 of the bristles 14 are rounded. At the same time, the arrangement of the bristles 14 allows a sufficiently high air flow between the individual bristles 14.
