Abstract

An oral hygiene implement is provided. The oral hygiene implement includes a housing; a movably mounted functional element; a fixation element that is secured at the housing and that essentially locks the functional element at the housing; and an axle that is supported by the fixation element. The functional element is arranged for movement around the axle and the fixation element extends through a cut-out or recess provided in a carrier element of the functional element, such that pulling the functional element out of the housing along the longitudinal axle extension direction is inhibited.

First claim

What is claimed is:

1. An oral hygiene implement comprising:
a housing;
a movably mounted functional element;
a fixation element that is secured at the housing and that essentially locks the functional element at the housing; and
an axle that is supported by the fixation element,
wherein the functional element is arranged for movement around the axle; and wherein the fixation element extends through a cut-out or recess provided in a carrier element of the functional element, such that pulling the functional element out of the housing along the longitudinal axle extension direction is inhibited, wherein the axle is supported at two locations provided at the carrier element, wherein the two locations are disposed on opposite sides of the fixation element.

2. The oral hygiene implement according to claim 1 , wherein the fixation element and the housing are non-detachably connected.

3. The oral hygiene implement according to claim 1 , wherein a shaft element is coupled to the functional element, the shaft element being arranged to drive the functional element into motion around the axle during operation.

4. The oral hygiene implement according to claim 3 , wherein the shaft element is eccentrically coupled to the functional element such that in a neutral position the coupling location lies in a plane going through the axle and being perpendicular to a longitudinal extension axis of the oral hygiene implement.

5. The oral hygiene implement according to claim 1 , wherein the fixation element is at least partly curved between a location where the fixation element is secured to the housing and a location where the axle is supported by the fixation element.

6. The oral hygiene implement according to claim 1 , wherein a spring element is arranged between the carrier element and the fixation element, such that the spring element biases the carrier element in a direction that essentially coincides with the direction of a load that would be applied onto the functional element during operation when the functional element is pressed against a surface.

7. The oral hygiene implement according to claim 6 , wherein the spring element is an integral part of the fixation element.

8. The oral hygiene implement according to claim 1 , wherein a portion of the functional element extends through an opening provided in the housing, the extending portion being different to a primary functional portion of the functional element and being disposed opposite to the primary functional portion.

9. The oral hygiene implement according to claim 1 , wherein the housing has an inwardly thickened portion at which the fixation element is secured.

10. The oral hygiene implement according to claim 1 , wherein the oral hygiene implement is a powered oral hygiene device having a drive unit arranged to drive the functional element into a movement around the axle during operation.

11. The oral hygiene implement according to claim 1 , wherein the oral hygiene implement is a detachable brush for an electric toothbrush.

12. An oral hygiene device comprising a handle and an oral hygiene implement according to claim 1 , that is detachably attached to the handle.
