Abstract

A toothbrush including a main member that includes a handle portion, a neck portion and a head portion. At least one brush member, which forms at least part of the brush head along with the head portion and is movable relative to the head portion, is disposed in the head portion. The at least one brush member can be moved under the effect of a cleaning movement manually exerted on the teeth.

First claim

The invention claimed is:

1. A toothbrush comprising:
a main body including a grip part, a neck part, and a head part; and
at least one first brush body and at least one second brush body that are each arranged in the head part and are each movable relative to the head part, the first brush body and the second brush body each forming, together with the head part, a part of a brush head, wherein:
the first brush body is rotatably mounted on the head part about a geometric rotation axis, within a rotation angle, and the first brush body is rotatable relative to the head part via a cleaning movement exerted manually onto a plurality of teeth, and
the second brush body is translatorily movably mounted on the head part along a longitudinal axis of the toothbrush, and the second brush body is translatorily movable relative to the head part via the cleaning movement exerted manually onto the plurality of teeth.

2. The toothbrush according to claim 1 , wherein the main body is manufactured in a single-part using an injection moulding method.

3. The toothbrush according to claim 1 , wherein the first brush body and the second brush body are movable independently of one another.

4. The toothbrush according to claim 1 , wherein the first brush body and the second brush body are coupled to one another via a coupler of a coupling mechanism, such that a movement of the first brush body activates a movement of the second brush body via the coupler.

5. The toothbrush according to claim 1 , wherein the second brush body is arranged on the head part next to the first brush body towards the grip part.

6. The toothbrush according to claim 1 , wherein the second brush body is translatorily movable along a slide guide.

7. The toothbrush according to claim 6 , wherein the slide guide includes a longitudinal guide body that is formed by the head part and on which the second brush body is slidingly guided via at least one guide element, the at least one guide element at least partly encompassing the longitudinal guide body.

8. The toothbrush according to claim 6 , wherein the slide guide includes a guide opening that is formed by the head part and along which the second brush body is slidingly guided via at least one guide element engaging into the guide opening.

9. The toothbrush according to claim 1 , wherein the first brush body is configured to be deflected about a rotation point in three axis directions via a joint connection to the head part.

10. The toothbrush according to claim 9 , wherein the joint connection is a ball joint, the ball joint including a joint head and a joint socket.

11. The toothbrush according to claim 1 , wherein a restoring member is provided on the head part or on at least one of the first brush body from body and the second brush body, the restoring member being configured to restore the at least one of the first brush body and the second brush body to an initial position from a rotative or translatory deflection.

12. The toothbrush according to claim 11 , wherein the restoring member is formed by a soft component with elastic characteristics.

13. The toothbrush according to claim 11 , wherein the restoring member is a spring.

14. The toothbrush according to claim 11 , wherein the restoring member includes at least one deflection element that is arranged on the head part laterally of the brush body and that projects laterally from the head part such that the deflection element is deflected in a movement direction via a catch contact with the at least one of the first brush body and the second brush body, upon a translatory displacement of the at least one of the first brush body and the second brush body.

15. A method for manufacturing the toothbrush according to claim 1 , wherein manufacturing of at least the main body is performed by an injection moulding method.
