Definitions

  • the invention relates to a toothbrush according to the preamble of the main claim.
  • the toothbrushes In order to avoid damage to the enamel in the area of the tooth neck and the gingival margin when brushing the teeth, the toothbrushes have either been provided with more resilient or softer bristles, which, however, are inadequate in their overall cleaning action, or, according to US Pat. No. 4,520,526, an elastic one between the brush head and the handle Connecting part is provided, which was designed so that the brush head with respect to the handle in a plane perpendicular to the bristle bed dodges under load, namely with a load of 100 to 300 g by about 6 mm or with a higher load by a larger amount accordingly an angle up to about 30 °.
  • the connecting part between the brush head and the handle has either been reduced in thickness with the same width, or a slot or elongated opening in the connecting part a plane arranged parallel to the bristle bed is provided so as to allow evasion in a plane existing perpendicular to the bristle bed.
  • toothbrushes with an area reduced in thickness of the connecting part are unsuitable for prolonged use because this area breaks easily; Toothbrushes with a slotted or perforated connecting part can only be produced with relatively great effort by injection molding compared to conventional toothbrushes; In addition, toothpaste residues accumulate in the slot, which after one week lead to unsanitary deposits and dirt accumulation or can only be cleaned in a laborious manner. In addition, such toothbrushes are not suitable for modern toothbrushing techniques.
  • the invention is based on the object of proposing a toothbrush which, even when the bristles are inclined in the direction of the gingival margin, compensates for force peaks when the brush head is loaded and thus in particular for the above-mentioned modern toothbrushing technique but also for the vibrating technique according to Dr. Bass or according to the Charters technique.
  • the toothbrushes provided according to the invention are particularly advantageous because they compensate for the force peaks at a load of 300 to 500 pond or more due to the bristle part which elastically deflects in each plane and ensure a much more uniform force distribution.
  • the toothbrush according to the invention is advantageous because it compensates for a given sequence of movements designed.
  • the toothbrush according to the invention can be easily produced by injection molding and can be permanently loaded in the connecting part between the bristle bed and the handle.
  • FIG. 1 a side view of the toothbrush according to the invention
  • FIG. 2 a top view of the toothbrush according to the invention
  • Figure 3a and b a section in the plane III-III through the handle of the toothbrush according to the invention.
  • the toothbrush consists of a brush head 2, which is connected to the handle 4 via the flexible connecting piece 6. Because the connecting part 6 has a smaller cross-section than the handle and the latter preferably has a square cross-section with the sides drawn in, the handle 4 is rigid, so that the flexibility or the evasion ⁇ , ⁇ of the brush head is achieved by the elastic intermediate part. The deflection is determined in the respective plane as the distance that the middle part of the bristle bed has from the starting position. It is in a range of about 0.6 to 2.5 cm and preferably 1.0 to 2.0 cm.
  • the special cross-sectional shape of the handle 4 according to FIGS.
  • FIG Bristle surface is made possible, both according to the vibrating technique of Dr. Bass as well as the Stillmann technique is required.
  • the outside bristle bundle 3 is colored differently from the other bristle bundles, in order to make it particularly clear to children, when brushing their teeth, to avoid evading, at least in the plane lying parallel to the bristle bed.
