Definitions

  • the invention relates to a toothbrush with an interchangeable brush head, which has a conical cavity between a bristle holder wall and an opposite brush head outer wall, into which a connecting piece of a handle part adapted to the cavity can be inserted.
  • Such toothbrushes with interchangeable brush heads are known (US Pat. No. 1,682,325).
  • the cavity receiving the conical connector is formed by a sleeve which is embedded on the outside of the brush head.
  • the connecting piece and the cavity are trapezoidal in cross section, so that the brush head can only be connected to the handle part in a certain position.
  • a fixed position of the brush head relative to the handle part is predetermined even when using the toothbrush. This can help with dental care not all areas of the teeth to be cleaned can be optimally reached.
  • the object of the invention is therefore to design a toothbrush of the type mentioned in such a way that two different relative positions between the handle part and the brush head can be achieved in a simple manner, so that the brush head can be brought into the most favorable position for cleaning. It must be ensured that the brush head can be replaced easily so that the user can easily replace different brush heads, for example with bristles of different hardness. This should also make it easier and cheaper to replace used brush heads in good time.
  • the connecting piece is angled relative to the handle part and that the connecting piece can be inserted into the brush head in two opposite positions. This results in two different angular positions of the brush head relative to the handle part by repositioning the brush head, which, when using the toothbrush, enables two different angular positions of the brush head to be adapted to the respective surface of the teeth to be cleaned.
  • a tongue-shaped, metal connecting piece 1 is made in one piece with an angled extension 2, which is anchored in a plastic handle part 3.
  • the extension 2 has lateral anchoring jaws 4.
  • a plastic brush head 5 carries. Bristles 7 inserted in a bristle carrier wall 6. Between the bristle carrier wall 6 and an opposite brush head outer wall 7 of the brush head 5, a cavity 8 is formed which is adapted in cross section to the connecting piece 1 and whose length is somewhat greater than the length of the connecting piece 1. As can be seen in particular from FIG. 2, the connector 1 and the cavity 8 are conical in the same way, so that the connector 1 fits into the cavity 8.
  • the angle ⁇ between the connector 1 and the longitudinal direction of the handle part 3 is preferably 7 °.
  • the brush head 5 can be fitted in two different positions on the connecting piece 1, which is either in the direction indicated in Figure 1 in a position rotated through 180 0 position, in which the boron - are directed most 7 in the opposite direction.
  • the brush head 5 can thus assume two different positions relative to the handle part 1.
  • a wedge piece 10 which tapers from the inner end of the cavity 8 toward the opening of the cavity 8 and protrudes from the brush head outer wall 9 and is shorter than the cavity 8.
  • the greatest height of the wedge piece 10 is preferably 0.3 mm.
  • the wedge piece 10 serves as a brake, which holds the connecting piece 1 securely in the brush head 5 and brings about a predetermined resistance against the pulling off of the brush head 5.
  • FIG. 7 and 8 show a modified embodiment of the connector form 1 ', which is in this case designed as a resilient wire bracket, the two wire ends of which form the extension 2' serving for anchoring in the handle 3.
  • the wire ends have compression ribs 11, the height of which is a maximum of 0.3 mm to the wire surface.
  • the two legs of the connecting piece 1 'designed as a wire bracket are provided with a bulge 12 which is formed by a curved wire section (FIG. 8).
  • a snap-off brake is provided, which consists of a protruding into the cavity 8 from the brush head -Exterior wall 9 protruding wedge-shaped elevation 13 and a locking recess in both sides of the connector 1, into which the wedge-shaped elevation 13 can be snapped.
  • the two-sided locking recesses of the conical connecting piece 1 are formed by a rectangular slot 14. In both positions of the brush head 5, the elevation 13 snaps into the slot 14, which corresponds in length and width to the elevation 13.
  • the embodiment according to FIG. 11 differs from this example only in that the latching-off brake instead of the wedge-shaped elevation 13 emerges as a dome-shaped elevation 15 projecting into the cavity 8 leads is.
  • the two-sided locking recesses of the conical connecting piece 1 are formed by a locking hole 16 (FIG. 12J) corresponding in length and width to the dome-shaped elevation 15 (FIG. 12J), which can also be square or a round bore 17 (FIG. 13).
  • the width of the conical connecting piece 1 or 1 ′′ and the width of the conical cavity 8 in the brush head 5 each have a tolerance range between 0 and - 0.05 mm, so that a secure fit between the brush head 5 and that with the connecting piece 1 provided handle part is guaranteed under all operating conditions, in particular very different temperatures.
  • the connecting piece 1 with the handle part 3 can be made in one piece from metal, for example from die-cast zinc-aluminum, the handle of the handle part 3 preferably being hollow.
  • the toothbrush can also be designed as a travel toothbrush, in which a short handle part, which carries the exchangeable brush head 5, can be inserted into a sleeve, which can be placed on the short handle part to use the toothbrush as a handle extension.
