Definitions

  • the invention relates to bristle goods with a bristle carrier and associated with this bristle, at least of which a part is combined into bristle groups in which the distance of the bristles is smaller than the distance of the geometric centers of adjacent bristle groups.
  • the free ends of the bristles are usually at the aforementioned bristles in a flat envelope.
  • surface In order to will have a good surface effect on the treated or surface to be machined, provided that surface is also a level.
  • surface With evenly curved Surfaces is at least a large number of bristles at the same time effective.
  • the one to be treated or processed Surface is discontinuously curved or has it even narrow recesses and gaps, so this can only individual bristles penetrate with a correspondingly strong pressure, however, causing damage to adjacent surfaces occur because of the greater pressure there can.
  • the invention is based, for bristle goods the task to propose training of any kind in which the Bristles both on the one to be treated or processed Surface are equally effective as in recesses or columns.
  • the Distance of the geometric center of at least one bristle group at least one from the geometric center adjacent bristle group is substantially the same or larger is as the product of the average of the number of bristles in the two bristle groups and the diameter of these Bristles.
  • a Bristleware according to the invention is characterized by the according to the invention proposed relation to conventional Bristles were generally of a smaller number of bristles in a group and by a larger one Distance of the groups from each other.
  • the bristle groups designed according to the invention are advantageous as a round, preferably as a bundle with a circular Cross section formed.
  • the bristles of a bristle group but can also be a different one, for example a triangular, polygonal or strip-like cross-sectional shape have, then the envelope circle of the cross section the diameter for the relation according to the invention between him, the number of bristles in the bristle groups and provides their distance.
  • the bristle groups in which the distance their geometric centers essentially the same or is greater than the product of the average of the number of Bristles of neighboring bristle groups and the diameter these bristles, on the bristle holder in the corners of a Triangles or polygons, especially a square, with if necessary arranged different side lengths, the shortest side length the relation according to the invention should have for the distance of the bristle groups.
  • the bristle groups where the distance of their geometric centers essentially is equal to or greater than the product of the Average of the number of bristles in adjacent bristle groups and the diameter of these bristles on the bristle carrier are arranged linearly.
  • the linearly arranged bristle groups can a complete one in several parallel lines Form bristles. But it can only be done in areas the bristle carrier provided such linear arrangements his. Is it a brush with a preferred one Working direction, this linear arrangement can, if necessary only be provided in the working direction. A such preferred working direction results, for example for red / white dental care, for the brush head transverse to its longitudinal extension from the gum towards the teeth are moved.
  • the number of bristles in the bristle groups can be the same or be different. Likewise, the diameter of the Bristles in the bristle groups are the same or different his. The distance between adjacent bristle groups must be correspondingly be adjusted.
  • a single bristle product e.g. a toothbrush
  • the formation of the groups according to the invention and their arrangement can also be combined with known arrangements.
  • the individually standing bristles to at least one bristle field be summarized, in which the bristles with little Are spaced from each other. 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 envelope can be convex or concave, in particular conical or partially spherical envelope surfaces are advantageous.
  • the bristles can have any cross-sectional shape have or those with a round cross section with such other cross-sectional shapes mixed in a bristle group his.
  • For non-round bristles is for dimensioning the distance between the bristle groups and the diameter of the enveloping circle of the bristle cross section is decisive.
  • the bristles of a bristle group can be used individually with the bristle holder or at their ends together and together be connected to the bristle holder.
  • the bristle groups with the bristle holder all come at the beginning mentioned mechanical or thermal processes in Question.
  • the section of a bristle field shown in FIG conventional toothbrush consists of bristle groups in the form of round bundles 1 consisting of a plurality of bristles 2 consist.
  • the bundle 1 have the diameter D and Bristles 2 have the diameter d.
  • Bundle 1 is with one Distance x from each other on a section Bristle holder 12 attached. Usually point conventional toothbrushes an equal distance x all Bundle in the attachment level on the bristle holder on.
  • Figure 1 is also a mechanical fastening method indicated, in which the bristles 2 of a bundle 1 looped and by means of an anchor in a hole in the bristle carrier 12 are attached. This procedure is described in brush technology referred to as "punching".
  • the fill level of the bundle is approx. 65%. This results in a bristle density of 791 bristles per cm 2 .
  • the bristle density is 796 bristles per cm 2 .
  • 3 to 6 the bristle or Bundle arrangement shown.
  • the bundle diameter D is shown in dashed lines. He also indicates the mounting surface of bundle 1 the bristle holder. In Fig.3b) is this mounting surface reproduced in cross-hatching.
  • Fig.6a shows two adjacent bundles with different Bristle number.
  • the distance x (Fig. 6b)) is calculated the average of the number of bristles (the sum is 9, that Means 4.5) and the bristle diameter d.
  • the bristle diameter d is also for bundles with different numbers of bristles a linear order of the bristles 2 in the brushing direction possible.
  • the distances between the bundles is recommended for a given bristle diameter a limitation of the number of bristles per bundle.
  • the distance x of the bundles should be approximately instead of 2.6mm 8.4mm.
  • FIG. 7 shows a plan view of the occlusal surface of teeth, for example the molars of a set of teeth. Adjacent teeth are 4 and the interdental space between them is 5 designated. Furthermore, the effect of a conventional one Toothbrush using the example of three arranged in a row Bundles 1 each with seven bristles 2 shown. The distance x the bundle 1 from each other is smaller than the product from the average of the number of bristles 2 of adjacent bundles 1 and the bristle diameter.
  • the distance x is equal to or greater than the product of the mean of Number of bristles 2 adjacent bundles and the diameter the bristles, it comes when brushing towards 6 am Inlet area of interdental space 5 not to be stowed the bristles, but all the bristles are lined up Bundle linearly, so that the interdental space 5 by a only brushing movement in one direction completely from the Bristles is detected.
  • Fig.12 arrange themselves regardless of the brushing direction 6 or 7 the bristles in the bundles one behind the other and can in this way up to the gingival margin 8 in the interdental space 5 penetrate.
  • Fig. 13 and 14 show a greatly enlarged section of a tooth 4 with a fissure 9.
  • Such fissures are in usually funnel-shaped and have one more or less extensive longitudinal extension.
  • Fig. 14 due to the possibility of linear ordering the bristles 2 at least part of them to the bottom the fissure 9 penetrates.
  • FIG. 15 illustrates a section of a tooth 4 with an ideally reproduced fissure 9 in linear Extent shows.
  • the bristles 2 of the bundle 1 line up linearly, whereby, as can be seen from the illustration, a Part of the bristles 2 penetrates into the base of the fissure 9.
