Brush section for an electric toothbrush
First Claim
1. A brush section for an electric toothbrush, comprisinga mounting tube in which a shaft rotatable mounted and driveable about a longitudinal axis is received, anda bristle carrier coupled to the shaft such that a rotary motion of the shaft about the longitudinal axis effects a rotary motion of the bristle carrier about a transverse axis that is transverse with respect to said longitudinal axis, wherein the bristle carrier is mounted directly on the shaft,and wherein the shaft is configured as a crankshaft having a first end and a second end, with the first end of the shaft providing the longitudinal axis while the second end of the shaft is arranged at an angle to the longitudinal axis.

Abstract
The invention is directed to a brush section (1) for an electric toothbrush which includes a mounting tube (2) in which a shaft (7) rotatably mounted about a longitudinal axis (3) and driveable in an oscillatory or rotary fashion is received. Further, the brush section (1) includes a bristle carrier (11) which is pivotally mounted on an angled end (19) of the shaft (7) configured as crankshaft and which, in operation of the electric toothbrush, is set in a rotary motion (26) about the transverse axis (14) by a pin (23). The angle (20) formed by the longitudinal axis (3) and the angled end (19) of the shaft (7) serves the added function of causing the bristle carrier (11) to perform a pivotal motion (27) about an axis (28).
