Definitions

  • the invention relates to bristleware with a bristle carrier and bristles connected to it, at least some of which are combined into bristle groups, in which the distance between the bristles is smaller than the distance between the geometric centers of adjacent bristle groups.
  • Bristle articles in the sense of the invention include brushes of all kinds, such as tooth, body, cleaning and cleaning brushes, application brushes, brushes and technical brushes, for example polishing and grinding brushes.
  • the bristles are generally combined into groups in the form of bundles or bristle fields.
  • the free ends of the bristles in the aforementioned bristle products usually lie in a flat envelope surface. This achieves a good surface effect on the surface to be treated or processed, provided that this surface is also a plane.
  • the invention is based on the object of proposing a design for bristle products of any kind in which the bristles are equally effective both on the surface to be treated or processed, as in recesses or gaps.
  • This object is achieved in that the distance of the geometric center of at least one bristle group from the geometric center of at least one adjacent bristle group is substantially equal to or greater than the product of the average of the number of bristles in the two bristle groups and the diameter of these bristles.
  • the bristles In the case of bristle goods with a conventional arrangement of a large number of bristles in a bundle, the bristles accumulate in the inlet area of gaps or depressions and at most penetrate individual, external bristles of the bundle into the depth. The reason is that the number and density of the bristles in the bundle in relation to the distance of the Bundle is large and the bristles cannot deflect to the necessary extent when painting over depressions or gaps, but rather are supported against one another in the predetermined bundle shape.
  • a bristle article according to the invention is generally characterized by a smaller number of bristles in a group and by a greater distance between the groups due to the relation proposed according to the invention compared to conventional bristle articles.
  • the bristle groups designed according to the invention are advantageously designed as round, preferably as bundles with a circular cross-section.
  • the bristles of a bristle group can, however, also have a different, for example a triangular, polygonal or strip-like cross-sectional shape, in which case the envelope circle of the cross section provides the diameter for the relation according to the invention, the number of bristles in the bristle groups and their spacing.
  • the bristle groups in which the spacing of their geometric centers is substantially equal to or greater than the product of the average of the number of bristles of adjacent bristle groups and the diameter of these bristles, are preferably on the bristle carrier in the tines of a triangle or polygon, in particular a quadrangle , with possibly different side lengths, the shortest side length having the relation according to the invention for the distance between the bristle groups.
  • the bristle groups in which the distance between their geometric centers is substantially equal to or greater than the product of the average of the number of bristles of adjacent bristle groups and the diameter of these bristles, are arranged linearly on the bristle carrier.
  • the linearly arranged bristle groups can form a complete bristle stock in several parallel lines.
  • such linear arrangements can also be provided only in areas of the bristle carrier. If it is a brush with a preferred working direction, this linear arrangement can optionally only be provided in the working direction.
  • Such a preferred direction of work results, for example, in red / white dental care, in which the brush head is moved transversely to its longitudinal extent from the gums in the direction of the teeth.

  • the individually standing bristles can be combined to form at least one bristle field, in which the bristles are thus arranged at a short distance from one another. This distance can be in the range of the diameter of the bristles.
  • a further optimization can be achieved in that the free ends of the bristles of at least one bristle group lie on a non-flat envelope surface.
  • This enveloping surface can be convex or concave, in particular conical or partially spherical enveloping surfaces are advantageous.
  • the free ends of the bristles of different bristle groups lie on different enveloping surfaces and that these enveloping surfaces optionally lie at different heights with respect to the surface of the bristle carrier.
  • the bristles can have any cross-sectional shape or those with a round cross-section can be mixed with those of other cross-sectional shapes in a bristle group.
  • the diameter of the enveloping circle of the bristle cross section is decisive for the dimensioning of the distance between the bristle groups.

Abstract

L'invention concerne un produit de brosserie comprenant un support (12) et des poils (2) reliées à ce support, au moins une partie des poils étant regroupée en groupes de poils (4), la distance entre les poils est inférieure à la distance (x) entre les centres géométriques de groupes de poils adjacents. Un tel produit de brosserie est caractérisé en ce que la distance (x) entre le centre géométrique d'au moins un groupe de poils (4) et le centre géométrique d'au moins un groupe de poils (4) adjacent est sensiblement identique ou supérieure au produit de la moyenne du nombre de poils (2) des deux groupes de poils et du diamètre (d) de ces poils. Cette conception et cette disposition permettent d'ordonner de façon linéaire dans le sens de brossage les extrémités fonctionnelles des poils de ces groupes de poils indépendamment de leur surface de fixation sur le support et peuvent pénétrer dans des fentes étroites et des creux.
