Definitions
- the invention relates to a toothbrush for simultaneously cleaning the teeth on both sides, consisting of a handle with bristle holders connected to it by a web and U-shaped in cross section, " which have bristles directed towards their inside.
- Such a toothbrush is used to simultaneously clean the front and back of the teeth in a single work step, possibly even simultaneously the teeth of the lower and those of the upper jaw.
- Such a toothbrush has become known from DE-PS 825 536.
- the bristle holders When viewed in the longitudinal direction, the bristle holders are adapted to the arch of the jaw, the bristles themselves are straight (perpendicular) to the holder.
- the disadvantage of this embodiment is that it is a rigid structure and such a bristle holder only fits a certain arch of the jaw. As a result, such a toothbrush is not generally usable and has not been used. It would be conceivable to make toothbrushes of different sizes, for example for children and adults, but this does not bring the desired success because there are many differences in jaws and teeth.
- the rigid design of the bristle part the conventional, relatively sharp-edged design of the bristle tips is very disadvantageous because it is not as with a toothbrush that can only be used on one side, the pressure on the teeth and thus on the gums can be individually regulated. , -
- the object of the invention was to create a toothbrush that is only one size and is suitable for a wide variety of jaw and tooth shapes.
- this goal is achieved in that the handle is designed to be pivotable relative to the bristle holder about an axis lying parallel to the body axis in the position of use and / or at least one bristle holder relative to the web about an axis parallel to the teeth in the position of use .
- this pivotability is designed to be elastic, which which can be done by a suitable choice of the material from which the bristle holders and the handle are made, or by a corresponding weakening of the material, which leads to predetermined kinks.
- the toothbrush according to the invention which inevitably provides a certain distance between the two U-legs and thus the bristle tips protruding from the inside thereof, it is expedient for better removal of the dental plaque by pushing action and for better gum massage if the bristles are on the bristle holders are inclined on both sides away from the web at an angle of approximately 1 to approximately 10 degrees, preferably facing away from 3 to 5 degrees, and / or if the bristles have an inclination of approximately 3 to approximately 15 degrees in the sliding direction of the toothbrush , preferably from 8 to 10 degrees from the center of the web back and forth.
- Fig. 2 shows the cross-sectional shape
- FIG. 1 shows a view of the toothbrush mentioned as an exemplary embodiment.
- a flat, upstanding web 2 is arranged on a holder 1 and is closed at the top and bottom with a bristle holder 3 and 4 each.
- These bristle holders 3 and 4 are fastened transversely above and below the web 2, so that a cross-section results in a double U-shaped or quasi-I-shaped part, as can be seen more clearly from FIG. 2.
- the position of the bristles 6 is important for an intensive cleaning process. They are now not inserted straight, ie at right angles in the bristle holders 3, 4, but at an oblique angle. As an extensive test series has shown, it is advantageous to arrange the bristles 6 in the bristle holders 3, 4 inclined on both sides of the web 2 at an angle alpha of the area mentioned above in order to improve the gum massage. Additionally or alternatively, the bristles 6 should have an inclination angle Beta of the range mentioned above in the sliding direction of the toothbrush. the center of the web as seen back and forth to improve the cleaning effect. The bristles 6 can have a length up to the mutual contact.
- a bristle holder for example the bristle holder 3, has a softer type of bristle 6 than the other bristle holder 4.
- the softer bristles are preferably provided, for example, to clean the inside of the teeth, and here a softer type of bristle is preferred.
- An essential component of the design according to the invention is the arrangement of notches 5 in the bristle holders 3 and 4. These are arranged in the sliding direction along the web 2, but on the outside. At least two notches 5 are provided, but a larger number is also expedient. The purpose of these notches 5 is that the bristle holders 3 and 4 can adapt teeth of different thicknesses by pivoting about the axis 8.
- toothbrushes according to the invention With its pushing and massage effect, is the rounding of the bristle tips, which is known per se in toothbrushes of another construction, in order to avoid injury to the gums.
- bristles 6 ′ can advantageously also be arranged on the web 2 in a manner known per se, which then clean the chewing surfaces of the teeth under one.
