Definitions

  • a toothbrush of the type mentioned is known from US Pat. No. 3,067,447, in which the brush parts are formed by flat brushes which are offset parallel to the respectively associated leg of the handle part.
  • the bristles of equal length which are at right angles to the teeth, only rub along the front and rear sides of the teeth, while the areas between the teeth remain essentially untreated, so that the deposits mentioned can arise here. It may be that when the toothbrush is moved back and forth, some bristles also get into such gaps. The depth of penetration and the frictional force are low here, however, since the other bristles are supported on the outside on the adjacent teeth.
  • the bristle carriers on their sides facing away from one another are bristle-free at least in the area facing the handle part, not only are relatively narrow brush parts obtained but also avoid chafing of the adjacent skin areas.
  • the bristle carriers taper on their bristle-free side towards the end facing away from the handle part, the space requirement is reduced even further, and even the narrowest parts of the mouth can be reached without any discomfort for the user.
  • the bristle-free area of the bristle carrier can extend from an angle of approximately 120 ° to 140 °, viewed from the plane of the handle part. Furthermore, the bristle carriers can be covered with bristles in the plane going through both bristle carriers transversely to the plane of the handle part beyond the apex.
  • the longitudinal direction of the brush parts expediently forms an angle of approximately 90 ° with the legs of the handle part. This gives a parallel position of the brush parts to the teeth with the handle part held horizontally, which is particularly advantageous for cleaning the interdental spaces by vertical movement.
  • a grip part 1, 1a, 1b is provided with which the device can be gripped by hand.
  • a brush part 2, 2a, 2b which has two brush parts 3, 3 '; 3a, 3'a; 3b, 3'b; 3d; 3e contains, which are designed in the manner of round brushes.
  • These brush parts carry conventional bristles that can be pressed in or fastened in some other way, and in the case of plastic as a production material, a one-piece molding is also possible.
  • the two brush parts 3, 3 'etc. form an angle of approximately 90 ° with the handle part legs 4, 4' etc., so that an approximately L-shaped configuration results in side view .
  • This facilitates the insertion and removal of the toothbrush and you can comfortably hold the handle part 1 etc. essentially horizontally by hand.
  • FIG. 4 corresponds to the exemplary embodiment according to FIGS. 1 to 3 with the exception mentioned that here the brush parts 3a, 3'a are not completely covered with bristles.
  • the bristles of the round brushes can sit on carrier pins 17, 17 '(FIG. 4) which are integrally formed on the handle part.
  • the brush sections consisting of carrier pins and bristles can also be produced separately.
  • Such a brush section 3d designed as a round brush is shown in FIG. 6.
  • the bristles are seated on a central support pin 20, which can be made of plastic or metal, expediently made of plastic.
  • This support pin has a pocket recess 18 into which an extension 19 protruding from the handle part can be inserted.
  • the extension can also be provided on the support pin and the bag recess on the handle part side (see FIGS. 7 and 8).
  • the connection can be made, for example, by gluing.
  • the brush section should be non-rotatably.
  • the sack recess 18 and the extension 19 could have a non-circular cross-section, e.g. B. give a square cross section. The same applies to the brush section 3e according to FIGS. 7 and 8.
  • each carrier pin is tapered on its bristle-free side 22 towards the free end, as can be seen from FIG. 7.
  • the beveled part can be a flat surface 24, the beveled part advantageously being able to be inclined by an angle ⁇ in the range of 10 ° relative to the pin axis 24.
  • this beveled part of the bristle-free side 22 adjoins an all-round cylindrical part 26 of the carrier pin, which for example can have a length 1 of approximately 2-3 mm.
