Definitions

  • the invention relates to a toothbrush according to the preamble of claim 1.
  • the toothbrush has proven itself as an important means of oral hygiene for decades. However, in order to be able to fight against the various diseases that threaten human teeth every day, it is necessary to be able to thoroughly clean all areas of the mouth.
  • the invention is therefore based on the object of further developing a toothbrush in such a way that it can be handled effectively and conveniently in accordance with the topography of the mouth.
  • the toothbrush according to the invention has an optimal complacency which allows an ergonomically exemplary handling of the same.
  • the hand of the user forms a ball socket when gripping the ball handle, which ensures safe and firm guidance of the toothbrush.
  • the relative position of the toothbrush in the hand can be varied in such a way that, apart from the usual position of the toothbrush, in which the handle between the thumb and index finger comes out of the hand, it can also emerge from the hand between any other fingers. without impairing handling.
  • the thin rod between the ball handle and the bristle carrier (s) enables the outer corners of the mouth to be reached without hindrance.
  • the spherical handle It is particularly advantageous to make the spherical handle hollow and to assemble it from two spherical half-shells, the handle being integrally formed on one spherical half-shell. In this way, the entire handle can be manufactured inexpensively in a simple manner using the plastic injection molding process. From ergonomic
  • the spherical half-shells are advantageously connected by gluing.
  • a circumferential groove or a Ste at the connection points of the spherical half-shells serves to center the two against each other and to improve the effectiveness of the bond.
  • the two spherical half-shells can also be assembled by means of a positive (snap) connection, which can be supported by additional adhesive if necessary.
  • a weighting piece is arranged in the lower region of the (hollow) ball handle. This shifts the center of gravity of the entire toothbrush into the lower half of the ball handle. which allows it to be parked in an almost upright position when not in use. The usual, unsanitary storage of the toothbrush in a toothbrush mug is no longer necessary. It is particularly effective if the arrangement of the weighting piece is such that the handle of the toothbrush which is parked assumes a position slightly inclined from an upright position, the bristles being inclined in the longitudinal direction towards their free ends. Rapid drying of the bristles is ensured in this way in that the water adhering to the bristles can run off to the inclined, free ends of the bristles.
  • the stability of the toothbrush can be improved by means of a stand area created by flattening the ball. Conveniently located the flattening in an area on the outer circumference of the ball grip, in which the weight piece attached from the inside is also located.
  • the weighting piece By forming the weighting piece as a permanent magnet, the toothbrush can be placed particularly well on metallic surfaces. If the magnetic weighting piece is dimensioned sufficiently, the toothbrush can also be arranged on upright or inclined metallic surfaces or can be attached hanging under metallic surfaces.
  • the space created within the hollow spherical grip can advantageously be used to accommodate an electric motor.
  • An electric motor of this type for example in connection with a swash plate, allows the bristle carrier to oscillate back and forth in the longitudinal direction of the stem.
  • the electric motor can be supplied with power either via an electrical line from an external energy source or from a built-in battery.
  • the inside of the ball handle can also be used in another way, for example by storing toothpaste in it.
  • Ball handle opposite end of the handle one or more bristle carriers pivotally arranged.
  • the pivoting range of the (elongated) bristle carrier (s) is selected such that they can be pivoted into two alternative positions that are different from one another by 90 °, namely transversely and longitudinally to the longitudinal direction of the stem. In this way, in connection with the ball handle, all the necessary functional areas in the mouth can be easily reached with maximum handiness of the toothbrush.

  • two curved bristle carriers 13 and 14 are rotatably arranged with rounded edges.
  • the ball handle 12 as part of the hand part 10 o is divided (Fig. 4). This is composed of an upper spherical shell 15 and a lower spherical shell 16. Cup on the upper Kugelgur ⁇ 15 of the handle 11 is integrally formed such that the center of the handle 11 is located approximately on the outside of the upper ball half-shell 15 0 and the longitudinal direction of the stem 11 extends in the direction of the ball normal. Thus, the stem 11 and the upper spherical shell 15 are integrally formed.
  • the lower spherical half-shell 16 5 has a cylindrical weighting piece 17 on the inside.
  • a build-up of material in the interior of the spherical half-shell 16 results in a likewise cylindrical receptacle 18 designed corresponding to the weighting piece 17.
  • the weighting piece 17 is fastened in the receptacle 18 by gluing. In addition or as an alternative to gluing, the weighting piece 17 can also be held in the receptacle 18 by friction.
  • the weighting piece 17 gives the entire toothbrush a center of gravity located in the area of the lower spherical shell 16. It is thereby achieved that the toothbrush which is not used can be placed on a base 19 0 with its ball handle 12 and handle 11 pointing upwards. Due to the arrangement of the weighting piece 17 shown in FIG. 4, the toothbrush always assumes a position in which the handle 11 and the bristle carrier 13, 14 are inclined in the direction of the bristles 20 arranged on the bristle carrier 13, 14. As a result, when the toothbrush dries, water can run off to the free ends of the bristles 20.
