Definitions
- the invention relates to a toothbrush with a bristle carrier equipped with bristle bundles on one side, with a handle and with a resilient connection between the handle and
- Bristle holder which, when pressure is exerted on the surface formed by the free ends of the bristle bundles, enables the bristle holder to deflect relative to the handle.
- the toothbrush is still the most essential and most reliable tool for essential dental hygiene.
- the bristles When cleaning the teeth with a brush, however, the bristles always exert pressure on the teeth and thus inevitably also on the gums. This pressure is very difficult to meter due to human feeling and the hand, so that on the one hand sufficient cleaning of the teeth and their spaces is achieved, but on the other hand the gums are not injured by excessive pressure.
- toothbrushes with a resilient brush head do not provide a remedy here, since they are designed so that the brush head yields when pressure is exerted, but the bristle surface is inclined away from the handle. This means that when pressure is exerted on the bristle head, the end-side bristles are inclined away from the cleaning surface, but the bristles on the handle side now exert an undiminished equal pressure on a substantially smaller brush surface.
- These toothbrushes are therefore not to be regarded as an improvement, but rather to be assessed disadvantageously, since the risk of injury to the Gums are not reduced, but are even enlarged by the smaller effective area of the bristle tips.
- EP 0 339 350 A1 describes a toothbrush whose brush head can be moved by a two-part handle, consisting of an upper part and a lower part, in such a way that the surface of the brush head can assume different angles to the handle.
- the disadvantage of this brush is that the inclination must be adjusted by hand and it can therefore not be avoided that either the bristles close to the handle or the brush tip are pressed more on the teeth and therefore there is no even pressure distribution over the entire Bristle surface there. Furthermore, to change the angle of inclination, a considerable effort of the hand is required, which cannot be controlled and metered for the desired purpose.
- the object of the invention is therefore the construction of a toothbrush, which has a resilient bristle head, such that when the brush head is deflected, the surface formed by the free bristle ends of the bristle bundles is not inclined away from the handle, but maintains the parallel alignment with the handle or against the handle tends to ensure that the full cleaning effect of the entire bristle surface is always used and that there are no pressure peaks against the gums.
- connection is formed by a quadrilateral joint, the axes of rotation of which extend transversely to the longitudinal extent of the handle and the bristles, and in that the distance between the two joints facing the bristle holder is less than or equal to the distance between the two joints facing the handle is.
- Fig. 1 a preferred form of toothbrush in Side view with a two-pronged connection between the handle and the brush head.
- Fig. 2 shows a preferred form of the toothbrush in supervision, in which a three-pronged connection is present between the handle and the brush head.
- FIG. 3 shows a sectional view of the toothbrush according to FIG. 2 along the section line A-B in a side view.
- FIG. 4 shows a sectional view of the toothbrush according to FIG. 2 along the section line C-D in a side view.
- FIG. 5 describes the mode of operation of a toothbrush according to FIG. 1 with two struts which are arranged parallel to one another.
- FIG. 6 describes the mode of operation of a toothbrush according to FIG. 1 with two struts which are arranged in a trapezoidal manner, i. H. on the handle part have a greater distance from each other than on the brush head.
- the invention relates to a toothbrush with a bristle carrier (1) which is resiliently connected to the handle (9) and has bristle bundles (10) arranged therein on one side and which can be moved in this way by exerting pressure on the surface of the bristle bundle (10) is that the bristle surface always runs parallel to the handle (9) or is inclined against it.
- connection points of the struts (4, 5) with the handle (9) or the bristle holder (1) Have the function of joints (2, 3, 6, 7).
- Tension struts (4) and push struts (5) are preferably tapered at these points to increase the resilient articulation.
- a spring effect can also be achieved by using a more elastic material in the area of the connection points.
- the toothbrush according to FIG. 1 has a tension strut (4) and a push strut (5), in which the respective distances between the joints (2) and (3) and (6) and (7) are the same.
