Abstract

An electric toothbrush attachment includes a longitudinal body extending in a first direction substantially away from an attachment location for attaching the longitudinal body to an electric toothbrush drive unit and a brush connected to an end of the longitudinal body, the brush having bristles extending in a second direction substantially inopposite to the first direction. The longitudinal body transitions into a proximal end having a brush mount portion via a transition region between the longitudinal body and the proximal end. The transition region is formed as an angle of approximately 90° between the longitudinal body and the proximal end. The proximal end further includes a brush mount portion that is adapted to hold a brush.

Claims

1. An electric toothbrush attachment comprising:

a longitudinal body extending in a first direction substantially away from an attachment location for attaching the longitudinal body to an electric toothbrush drive unit, the longitudinal body transitioning into a proximal end via a transition region between the longitudinal body and the proximal end, the proximal end having a brush mount portion holding a brush by two or more axles that support a corresponding number of gears that allow a circular movement of the brush, the brush having bristles extending in a second direction substantially inopposite to the first direction and capable of having a pivoting motion about an axis parallel to the first direction.

2. An electric toothbrush attachment comprising:

an elongated attachment body that transitions into a proximal end having a brush mount portion via a transition region between the attachment body and the proximal end;

a brush mounted perpendicularly to the attachment body with respect to a longitudinal axis of the attachment body, the brush mount portion holding the brush by two or more axles that support a corresponding number of gears that allow a circular movement of the brush; and

a plurality of bristles extending perpendicularly away from a bristle mounting face of the brush and having a pivoting motion about an axis parallel to the longitudinal axis.

3. An electric toothbrush attachment comprising:

an elongated attachment body that transitions into a proximal end having a brush mount portion via a transition region between the attachment body and the proximal end, the attachment body having a longitudinally extending drive member;

the brush mount portion is holding a brush by two or more axles that support a corresponding number of gears that allow a circular movement of the brush, the brush communicating with said longitudinally extending drive member and having bristles extending substantially parallel with said longitudinally extending drive member and having a pivoting motion about an axis parallel to the longitudinally extending drive member.
