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 same also applies to application brushes of any kind, as well as brushes for cleaning profiled surfaces or such surfaces that are covered by regular joints, depressions or the like. are interrupted. Brushes for cleaning the joints of tile surfaces are examples.
- the number of bristles in the bristle groups can be the same or different.
- the diameter of the bristles in the bristle groups can be the same or different. The distance between adjacent bristle groups must be adjusted accordingly.
- the formation of the groups according to the invention and their arrangement can also be combined with known arrangements.
- 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.
- the bristles of a bristle group can be connected individually to the bristle holder or at their ends to one another and jointly to the bristle holder. For the connection of the bristle groups to the bristle carrier, all the mechanical or thermal methods mentioned at the beginning can be used.
- FIG. 1 shows a section of a bristle field of a conventional toothbrush with round bundles on a scale of approximately 10: 1;
- FIG. 2 shows a section of the bristle field corresponding to FIG. 1 of a known toothbrush closest to the invention on a scale of approximately 10: 1;
- 3 to 6 each show a top view (a) of a bristle group in the starting position and a top view (b) of two adjacent bristle groups in the order formed according to the invention during use; 7 shows a plan view of the occlusal surface of adjacent teeth with an interdental space when cleaning with a conventional toothbrush;
- FIG. 8 shows a side view of the representation according to FIG. 7;
- FIG. 9 shows a plan view of the occlusal surface of adjacent teeth when using a toothbrush with the arrangement of the bristle groups according to the invention.
- Fig. 10 is a side view for illustration according to
- Fig. 11 is a side view of adjacent teeth
- FIG. 12 shows a representation corresponding to FIG. 11 when cleaning with a toothbrush with the arrangement of the bristle groups according to the invention
- FIG. 13 is a greatly enlarged sectional view of a fissure when using a conventional toothbrush
- FIG. 14 shows a representation corresponding to FIG. 13 when using a toothbrush with the arrangement of the bristle groups and bristles according to the invention
- 15 shows a perspective view of an individual bristle group according to the invention in an application case corresponding to FIG. 14.
- the drawing shows only bristle groups in the form of bundles with a circular cross section and bristles with a likewise circular cross section.
- the bundle diameter is always denoted by "D”
- the bristle diameter by "d”
- other cross-sectional shapes can also be provided, in which case the envelope circle of the bundle cross-section has the diameter D or the bristle cross-section has an envelope circle with the diameter d.
- the section shown in Fig.l of a bristle field of a conventional toothbrush consists of bristle groups in the form of round bundles 1, which consist of a plurality of bristles 2.
- the bundles 1 have the diameter D and the bristles 2 have the diameter d.
- the bundles 1 are fastened at a distance x from one another on a bristle carrier 12 shown in sections.
- conventional toothbrushes are at the same distance x from all bundles in the fastening plane on the bristle holder.
- FIG. 1 also indicates a mechanical fastening method in which the bristles 2 of a bundle 1 are looped and fastened in a hole in the bristle carrier 12 by means of an anchor. This process is referred to as "punching" in brush technology.
- 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 according to the invention is shown.
- the bundle diameter D is shown in dashed lines. It also indicates the attachment surface of the bundle 1 on the bristle carrier.
- this mounting surface is shown in cross hatching.
- Fig. 6a shows two adjacent bundles with different numbers of bristles.
- the distance x (Fig. 6b) is calculated from the average of the number of bristles (the sum is 9, the average is 4.5) and the bristle diameter d. In this way, a linear arrangement of the bristles 2 in the brushing direction is possible even with bundles with different numbers of bristles.
- a limitation of the number of bristles per bundle is recommended for a given bristle diameter.
- the distance x of the bundles would have to be approximately 8.4 mm instead of 2.6 mm.
- FIG. 7 shows a plan view of the occlusal surface of teeth, for example the molars of a set of teeth. Adjacent teeth are labeled 4 and the interdental space between them 5. Furthermore, the effect of a conventional one
- Toothbrush is shown using the example of three bundles 1 arranged one behind the other, each with seven bristles 2.
- the distance x between the bundles 1 is smaller than the product of the average of the number of bristles 2 of adjacent bundles 1 and the bristle diameter. If such a bristle arrangement movement in the direction of arrow 6 over the occlusal surface of teeth 4, the bristles of the leading bundle 1 still penetrate into the interdental space 5, but the bristles of the following bundles accumulate at the constriction leading to the interdental space 5, such as this is shown in Fig.7. It can be seen in the side view according to FIG. 8 that the bristles increasingly bend backwards in the direction opposite to the brushing direction 6.
- the bristles do not build up when brushing in direction 6 at the inlet region of the interdental space 5 , but all the bristles are lined up
- the bristles in the bundles are arranged one behind the other and can penetrate into the interdental space 5 up to the gingival margin 8 in this way.
- 13 and 14 show a greatly enlarged section of a tooth 4 with a fissure 9.
- fissures are generally funnel-shaped and have a more or less extensive longitudinal extent.
- the bristles 2 of the bundles 1 engaging in the fissure 9 from above accumulate in the narrowing inlet area of the fissure 9, while in the arrangement according to the invention measured according to FIG. 14 due to the possibility of the linear arrangement of the bristles 2 at least part of it penetrates into the bottom of the fissure 9.
- FIG. 15 shows a section of a tooth 4 with an ideally reproduced fissure 9 in a linear extension.
- the bristles 2 of the bundle 1 line up in a linear manner, wherein, as can be seen from the illustration, some of the bristles 2 penetrate into the base of the fissure 9.
