Definitions

  • the invention relates to a toothbrush according to the preamble of the main claim.
  • the toothbrushes In order to avoid damage to the tooth enamel in the tooth neck area and the gingival margin when brushing the teeth, the toothbrushes have either been provided with more resilient or softer bristles, but their overall cleaning effect is inadequate, or an elastic connecting part has been provided between the brush head and the handle in accordance with US Pat. No. 4,520,526. which was designed so that the brush head diverts relative to the handle in a plane perpendicular to the bristle bed under load, namely with a load of 100 to 300 g by about 6 mm or with a higher load by a larger amount corresponding to 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 a slotted or perforated connecting part can only be produced by spraying in relation to conventional toothbrushes in a relatively complex manner; furthermore, toothpaste residues accumulate in the slot, which after a week lead to unsanitary deposits and dirt accumulation or can only be cleaned in a laborious manner.
  • 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 bristles penetrate into the interdental niches and into the sulcus by means of the small circular movement and contribute to a good cleaning of particularly endangered denture sections.
  • 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 through the bristle part which elastically deflects in each plane and ensure a much more even 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 is easy to manufacture by injection molding and can be permanently loaded in the connecting part between the bristle bed and the handle.
  • 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 drawn-in sides, the handle 4 is rigid, so that the flexibility or the evasion ⁇ . ⁇ of the brush head is achieved by the elastic intermediate part.
  • the deviation in the respective plane is determined 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. 3a and 3b is particularly advantageous in the case of a resilient brush head in order to keep the brush head in the desired position and is ergonomically expedient, a cross-section according to FIG Bristle surface is made possible, both according to 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.
