Abstract

The invention is directed to a brush holder for a toothbrush, in particular for cleaning the interproximal spaces, for releasably locating a brush preferably comprising an in particular stem-shaped bristle supporting structure having bristles secured thereto, with the bristle supporting structure including a portion carrying no bristles, and the brush holder including a receiving structure adapted to receive the bare portion. The brush holder is of an approximately disk-shaped configuration. The receiving structure is associated with a recess, and the recess carries pivotally therein a clamping structure for clampingly, yet releasably, positioning the brush in its proper location relative to the brush holder.

Claims

1. A brush holder for a toothbrush for cleaning the interproximal spaces, said brush holder for releasably locating a brush including a stem-shaped bristle supporting structure having bristles secured thereto, the bristle supporting structure including a bare portion carrying no bristles, said brush holder comprising an approximately disk-shaped body having a receiving means adapted to receive the bare portion of the stem-shaped structure, said body also having a recess proximate to said receiving means, and said brush holder also comprising a clamping means that the recess carries pivotally therein, said clamping means for clampingly, yet releasably, positioning the brush in its proper location relative to the brush holder.

2. A brush holder as claimed in claim 1, wherein the clamping means pivots about a pivot axis extending parallel to a center line of the receiving means.

3. A brush holder as claimed in claim 2, wherein the recess extends into the receiving means and wherein the receiving means includes an enlarged portion adjacent to where the recess extends into the receiving means.

4. A brush holder as claimed in claim 3 wherein the receiving means is configured as a bore.

5. A brush holder as claimed claim 4 wherein the bore is provided with a diameter slightly larger than that of the stem-shaped structure.

6. A brush holder as claimed in claim 4, wherein said body includes an upper end having a frusto-conical projecting portion with the bore being arranged in the center thereof.

7. A brush holder as claimed in claim 6, wherein the bore (58) includes an entrance opening having a countersunk portion.

8. A brush holder as claimed in claim 2, wherein the clamping means is substantially configured as a hook-shaped clamping lever having at one end a nose-shaped section.

9. A brush holder as claimed in claim 2 wherein the brush holder is adapted to be driven in a rotating or oscillating fashion about an axis of rotation substantially coinciding with a center line of the receiving means.

10. A brush holder as claimed in claim 9, wherein the brush holder is configured so as to be essentially symmetrical about the axis of rotation.

11. A brush holder as claimed in claim 1 wherein the pivot axis of the clamping means is laterally offset from a longitudinal center plane of the brush holder.

12. A brush holder as claimed in claim 1 wherein the recess and the clamping means are substantially the same size.

13. A brush holder as claimed in claim 12, further comprising a second recess between a hook end of the clamping lever and the body of the brush holder.
