Definitions

  • the invention is therefore based on the object, a broom, a scrubber, a brush or the like. To be designed so that a smaller wall thickness of the bristle body is sufficient, so that the material used for the bristle body is reduced.
  • the outer region of the bristle body, where a bristle assembly is to be attached is formed by a wall section of softer material than the rest of the base body, and in that the thickness of the bristle tuft and thus the size of the loop on the one hand and the depth of the base body located end portion of the blind hole are coordinated so that the side portions of the loop are at least partially pressed laterally into the softer material of the outer wall section, the ends of the wire loop penetrate less deeply into the base body, ie its minimum wall thickness is reduced. This also reduces the overall material expenditure for the bristle body at the same time.
  • a broom or similarly a scrubber has a hollow bristle body 1 which has a constant cross section in its longitudinal direction. It has a hollow chamber 2, which accordingly extends in the longitudinal direction and is open to the outside at the top of the bristle body 1 via a slot 3. On both sides of the slot 3, these are provided with retaining webs 4 which are directed towards one another.
  • This design can be of interest if, as materials for the base body on the one hand and the outer section on the other hand, plastics are used which can still be coextruded together, but whose adhesion is not sufficiently great, so that a mechanical connection must also be produced.
  • the material of the base body 12 of the bristle body 1 and the wall section 14 made of significantly softer plastic each have a consistently homogeneous consistency and thus hardness that is constant over their respective cross section.
  • the punching i.e. the insertion and anchoring of a tuft of bristles 16 in a blind hole 17 is basically carried out in a known manner, i.e. around the still stretched bristles 21 of a bristle tuft 16, a wire loop 22 is placed in the middle thereof and then the bristle tuft 16 is punched into the blind hole, the ends 23 of the loop 22 being directed downward towards the end section 20.
  • the punch presses against the upper middle region 24 of the loop 22 lying between the ends 23 of the loop 22 and thus simultaneously against the tufts of bristles 16.
  • the ends 23 of the loop 22 penetrate in a conical shape due to this pressure, as can be seen particularly from FIG. 3 End portion 20 of the blind hole 17 in the base body 12.
  • the foot 27 of the bristle tuft is arranged not only in the end section 20 located in the base body 12, but also in the section 19 of the blind hole 17 located in the wall section 14.
  • the end section 20 located in the base body 12 must not be drilled so deeply into the base body 12 that it supports the foot 27 of the tufts of bristles 16 and can completely accommodate the sling 22.
  • the blind hole 17 must be so deep overall that the side portions 25 of the loop 22 do not extend outward beyond the edge 26 of the blind hole.
  • the wire loop 22 is given the approximately heart-shaped shape shown in FIG.
  • the bristle body 1 in the embodiment according to FIGS. 1 to 3 in its application for brooms or scrubbers has an approximately semicircular cross section which is open at the top through the slot 3, the bristle body 31 in the embodiment according to FIG. 4 is closed all round.
  • This bristle body 31 is preferably used to manufacture brushes.
  • a bristle assembly 32 - as indicated in FIG. 4 - can only extend over part of the length of the bristle body 31; in this case the part of the bristle body 31 which is not equipped with bristles can be used as a stem 33. If - as in the case shown in FIG.
  • the bristle body 31 in turn has a hollow chamber 34 and a relatively flat, for example approximately lenticular cross section, it can be expedient be to provide an intermediate wall 35 which counteracts too much compression of the bristle body 31.
  • the bristle body 31 has a base body 36 made of relatively hard material and a wall section 37 made of significantly softer material. This wall section 37 is formed in the area provided for the bristle assembly 32. Otherwise, the details from the description of the exemplary embodiment according to FIGS. 2 and 3 also apply here.
  • end pieces 38 are generally provided at the two ends of the bristle body 31, only one of which is shown.
  • the bristle assembly extends over the full length of the bristle body, then this will have a cross section which enables the side regions to be gripped.
  • the cylindrical section 19 of the blind hole 17 in the wall section 14 has a smaller diameter than in the base body 12. This results from the fact that when drilling a hole in rubber-like material not a hole corresponding to the diameter of the drill is cut, but a hole of smaller diameter. The rest of the material is only pushed away to the side and partially closes the hole again after pulling out the drill.
  • This effect leads to the fact that in particular the region of the wall section 14 located between the edge 26 of the blind hole 17 and the side sections 25 of the loop 22 is constricted and completely encloses the tufts of bristles 16. This largely prevents the ingress of dirt and, in particular, the deposition of dirt. The extent of this effect depends on the one hand on the hardness of the soft material forming the outer wall section 14 and the distance between the edge 26 of the blind hole 17 from the side sections 25 of the loop 22.
