Abstract

A hairbrush device ( 100 ) comprises a first plurality of brush filaments ( 112 ) and a second plurality of brush filaments ( 116 ). A property of the first plurality of brush filaments ( 112 ) and a respective property of the second plurality of brush filaments ( 116 ) are different from one another. In order to reversibly select a stiffness of the hairbrush device, the hairbrush device ( 100 ) comprises an actuation element ( 104 ) being in driving connection with the first and second plurality of brush filaments ( 11, 116 ) and configured for being actuatable for selecting the first plurality of brush filaments ( 112 ) or the second plurality of brush filaments ( 116 ) for a use.

First claim

The invention claimed is:

1. A hairbrush device comprising:
a first plurality of brush filaments; and
a second plurality of brush filaments;

where the first and second pluralities of brush filaments have different properties from one another and are adapted to be selectively actuated for use;
an actuation element in driving connection with the first and second plurality of brush filaments and configured to effect selective actuation of the first plurality of brush filaments or the second plurality of brush filaments for use; and
a filament carrier to which the first and second pluralities of brush filaments are connected, said actuation element being in driving connection with the filament carrier such that the filament carrier is rotatable around a central axis of the filament carrier between a first position associated with the first plurality of brush filaments being selected for use and a second position associated with the second plurality of brush filaments being selected for use.

2. The hairbrush device according to claim 1 comprising a gearwheel affixed to the filament carrier for rotation around the central axis of the filament carrier and including radially outwardly extending teeth relative to said central axis, said actuation element being rotatable around a longitudinal axis thereof and including radially inwardly extending teeth relative to said longitudinal axis for engaging with said radially outwardly extending teeth of said gearwheel.

3. A hairbrush device comprising:
a first plurality of brush filaments; and
a second plurality of brush filaments;

where the first and second pluralities of brush filaments have different properties from one another and are adapted to be selectively actuated for use; and
an actuation element in driving connection with the first and second plurality of brush filaments and configured to effect selective actuation of the first plurality of brush filaments or the second plurality of brush filaments for use; and
a handle connected to the actuation element in a rotationally movable way.

4. The hairbrush device according to claim 3 , where the actuation element comprises first and second recesses configured for cooperating with the handle to secure said actuation element in either a first or a second rotational position relative to the handle to effect said selection of either the first plurality of brush filaments or the second plurality of brush elements, respectively.

5. A hairbrush device comprising:
a first plurality of brush filaments; and
a second plurality of brush filaments;

where the first and second pluralities of brush filaments have different properties from one another and are adapted to be selectively actuated for use; and
an actuation element in driving connection with the first and second plurality of brush filaments and configured to effect selective actuation of the first plurality of brush filaments or the second plurality of brush filaments for use; and

a plurality of filaments carriers to which respective pairs of the first and second pluralities of brush filaments are connected, said actuation element being in driving connection with the plurality of filament carriers such that the plurality of filament carriers are each rotatable around a respective central axis between a first position associated with the first plurality of brush filaments being selected for use and a second position associated with the second plurality of brush filaments being selected for use.

6. The hairbrush device according to claim 5 where the central axes of the filament carriers are arranged around a common central longitudinal axis and, when positioned for use, the first plurality of brush filaments and the second plurality of brush filaments are arranged in radially extending rows relative to the longitudinal axis.

7. The hairbrush device according to claim 5 where the different properties of the first and second pluralities of brush filaments include at least one of:
different arrangements of the brush filaments,
different colors of the brush filaments,
different lengths of the brush filaments,
different thicknesses of the brush filaments, and
different materials of the brush filaments.

8. A hairbrush device comprising:
a first plurality of brush filaments; and
a second plurality of brush filaments;

where the first and second pluralities of brush filaments have different properties from one another and are adapted to be selectively actuated for use; and
an actuation element in driving connection with the first and second plurality of brush filaments and configured to effect selective actuation of the first plurality of brush filaments or the second plurality of brush filaments for use; and

a tubular base body including a plurality of apertures, said selective actuation of the first plurality of brush filaments being associated with the first plurality of brush filaments extending through the plurality of apertures, and said selective actuation of the second plurality of brush filaments being associated with the second plurality of brush filaments extending through the plurality of apertures.

9. The hairbrush device according to claim 3 and comprising a filament carrier having an elongated body with first and second opposing sides, the first plurality of brush filaments being arranged at the first side and the second plurality of brush filaments being arranged at the second side.

10. A hairbrush device comprising:
a tubular housing having a plurality of apertures therein;
at least one filament carrier rotatably supported within the tubular housing and having first and second portions holding respective first and second pluralities of filaments, a property of the first plurality of filaments being different than a property of the second plurality of filaments; and
an actuation element coupled to the at least one filament carrier and adapted to selectively rotate said filament carrier to either:
a first position where the first plurality of filaments extend through respective ones of the plurality of apertures in the housing; or
a second position where the second plurality of filaments extend through respective ones of the plurality of apertures in the housing.
