  • Publication number: 20080209649
    Abstract: A toothbrush and toothbrush head with a bristle carrier, on which a bristle section featuring a multitude of filaments is arranged. At least one filament is provided with a taper on its free end with a shape other than a rotationally symmetrical shape to preserve a high flexural strength of the filament in one direction. The taper is a flat-pressed scarfing such that the filament has a greater flexural strength with respect to a first lateral axis than with respect to a second lateral axis perpendicular to the first lateral axis in the region of the taper. The flat-pressed scarfing at the point of the filament improves penetration into the interdental spaces, while the higher geometrical moment of inertia of the wide side reduces the bending of the filament during use.

  • Patent number: 6041514
    Abstract: The invention is directed to an impeller (1) for a hair dryer or a hair dryer accessory device, which includes an impeller blade (6) by means of which the impeller (1) is adapted to be set in rotation about an axis (3) by a current of air (8). The impeller blade (6) possesses variable aerodynamic properties, particularly an effective surface impinged by the current of air (8) which is variable in response to the rotational frequency of the impeller blade (6). In particular the free end (7) of the impeller blade (6) is of an elastic configuration, causing it to be bent more or less severely under the action of the centrifugal force. This variation in the effective surface of the impeller blade (6) enables the rotational frequency of the impeller (1) to be maintained at an approximately constant value.

  • Patent number: 5867856
    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) is received which is mounted so as to be rotary about a longitudinal axis (3) and is adapted to be driven in an oscillatory fashion. Further, the brush section (1) includes a bristle supporting structure (11) which is arranged so as to be rotary about a transverse axis (14) by means of a bearing pin (18) and is adapted to be set in a rotational motion (29) about said transverse axis (14) by means of a drive pin (24). The fixed connection between the bearing pin (18) and the shaft (7) has the added effect of causing the bristle supporting structure (11) to perform a pivotal motion (28) about the longitudinal axis (3). The rotational motion (29) of the bristle supporting structure (11) produces a cleaning action on a user's exposed tooth surfaces, whilst the pivotal motion (28) acts to accomplish an additional cleansing operation on the user's inter-proximal surfaces.

  • Patent number: 5862558
    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) rotary about a longitudinal axis (3) is received. Further, the brush section (1) includes a bristle carrier (11) from which bristles (15) extend in the direction of a brush axis (14). The bristle carrier (11) is rotary about a transverse axis (19) by means of a bearing pin (21). By means of in particular a tapered disk (24), the brush axis (14) and the transverse axis (19) define between them an angle (28) departing from an apex (29). In operation of the electric toothbrush, the bristle carrier (11) performs a nutating motion about the transverse axis (19). This effects a revolving approaching/receding motion of the free ends of the bristles (15) resulting in an improved cleaning action on a user's teeth.
