Definitions

  • the present invention relates to a toothbrush according to the preamble of claim 1.
  • toothbrushes are known in which the bristle holder carrying the bristles and the handle are connected to one another in an articulated manner, which makes it possible to change the position of the bristle holder with respect to the handle.
  • toothbrushes of this type are shown, in which the bristle holder and the handle are connected to one another by means of a swivel joint, the axis of rotation of which, at least in the region of the swivel joint, is aligned with the longitudinal axes of the bristle holder and the handle.
  • This means that the brush surface defined by the bristle ends essentially always runs approximately parallel to the longitudinal axis of the handle in each position of the bristle carrier.
  • French patent 611,386 shows a toothbrush in which the articulated connection between the handle and the bristle holder is designed in such a way that the bristle holder can be pivoted about an axis which is essentially perpendicular to the longitudinal axis of the handle and can be switched between two positions. In both positions of the bristle holder, the brush surface runs at an angle to the longitudinal axis of the handle.
  • the adjustability of the bristle holder allows easier and more thorough cleaning of a larger part of the teeth of a bit in all toothbrushes mentioned above than is possible with toothbrushes without an adjustable bristle holder.
  • the present invention has for its object to provide a toothbrush of the type mentioned simple construction, the bristle holder can be easily adjusted in position with respect to the handle so that an equally thorough cleaning of all teeth of a bit is possible.
  • the articulated connection between the bristle holder and the handle is designed such that the brush surface can be brought from a first position, in which it runs approximately parallel to the longitudinal axis of the handle, to a second position and vice versa, in which the brush surface is at an angle to the longitudinal axis of the handle, the same toothbrush can be adjusted by moving the bristle holder relative to the handle without difficulty to the respective application, namely cleaning the front teeth on the one hand and cleaning the rear teeth on the other.
  • the toothbrush shown in Figures 1 and 2 consists of a straight handle 1 and a bristle holder 2 with a brush 3, which is formed by bristles 4, the ends of which form a brush surface 5.
  • this brush surface 5 lies in a plane which is denoted by E in the figures. It is of course also conceivable to design the brush surface 5 instead of being curved.
  • the bristles are held in a bristle holding part 6 which is angled relative to a neck part 7 of the bristle holder 2.
  • the longitudinal axis 6a of the bristle holding part 6 and the longitudinal axis 7a of the neck part 7 consequently run at an angle ⁇ to one another.
  • the bristle carrier 2 and the handle 1 are connected to one another via a swivel joint 9.
  • This hinge 9 consists of a hinge pin 10 protruding from the bristle carrier 2, which engages in a blind hole 11 in the handle 1.
  • the longitudinal axis 10a of the pivot pin 10 is aligned with the longitudinal axis 7a of the neck part 7. This also applies to the longitudinal axis 11a of the blind hole 11, which consequently forms an angle ⁇ with the longitudinal axis 1a of the handle 1.
  • the bristle carrier 2 can accordingly be rotated about the longitudinal axis 7a or the longitudinal axis 10a of the neck part 7 or the pivot pin 10.
  • the handle 1 and bristle holder 2 assume the mutual position shown in FIG. 2.
  • the brush surface 5 (and thus also the plane E) and the longitudinal axis 1a of the handle 1 form an angle 2 a, which is twice as large as the angle designated by ⁇ in FIGS. 1 and 2.
  • the toothbrush is bent at two points by the angle ⁇ , as can be clearly seen in FIG. 2.
  • the toothbrush can be easily handled when cleaning the rear teeth.
  • locking means In order to ensure that the bristle holder 2 is held in its respective position with respect to the handle 1, locking means must be provided which prevent the bristle holder 2 from being rotated unintentionally with respect to the handle 1.
  • Such locking can be achieved, for example, by a suitably designed fit between the pivot pin 10 and the blind hole 11. The frictional forces occurring between the pivot pin 10 and the wall of the hole 11 prevent the bristle carrier 2 from being rotated unintentionally, but allow the bristle carrier 2 to be rearranged when the appropriate force is applied.
  • FIG. 3 A variant of the various other possibilities for the formation of the locking means is shown purely schematically in FIG. 3.
  • a projection 13 is provided on the end face 12 of the neck part 7 of the bristle carrier 2, which cooperates with two diametrically opposite recesses 14 and 15 which are arranged on the end face 16 of the handle 1.
  • the projection 13 engages either in the depression 14 or in the depression 15 in the handle 1.
  • a depression can be provided instead of the projection 13, while two projections are to be provided instead of the two depressions 14, 15.
  • the swivel joint 9 can also be designed differently than shown.
  • the pivot pin 10 can be attached to the handle 1 instead of the bristle holder 2, while the blind hole 11 is formed in the bristle holder 2.
  • a swivel joint can also be provided, the axis of rotation of which runs perpendicular to the longitudinal axis 1a of the handle 1 and parallel to the plane E.
  • the axis of rotation is perpendicular to the plane of the drawing.
  • a suitable locking device must also be provided in order to lock the bristle holder 2 in the two desired positions.
  • This locking device can for example be designed as a locking device.
