The attachment part has a tubular connecting piece adapted to be connected to a neck of a handle section of the toothbrush, wherein the connecting piece has an inner and outer tubular structure forming a double cone comprising an inner and an outer conical surfaces that face each other and that define an essentially ring-shaped groove therebetween, wherein the inner and outer conical surfaces are structured and configured to be engaged with inner and outer conical surfaces of the neck of the handle section.

Abstract: A tool head for an electric toothbrush has at least one tool carrier movably supported on a base part by means of a bearing device. The bearing device includes rotational support means for rotatably supporting the tool carrier about an axis of movement and axial support means for axially movably supporting the tool carrier along the axis of movement, and drive means for driving the tool carrier in an oscillating manner to rotationally oscillate about said axis of movement and to axially oscillate along said axis of movement. The drive means include a cam surface for transforming a rotation of said tool carrier into axial movement of the tool carrier relative to the base part along the axis of movement.

Abstract: A toothbrush handle part of an electric toothbrush has a handle part neck connectable to an attachment, at least one drive element for driving the attachment, said drive element being supported movably relative to said handle part neck, and a retarding element for retarding and/or locking and/or blocking and/or slowing down the drive element.

Abstract: The invention relates to an electric toothbrush. In one embodiment, the invention relates to the toothbrush handle part having a coupling device for coupling an attachment thereto, especially an attachable brush, and a drive train, especially a drive shaft, which can be driven by a drive motor, for driving the attachment. In another embodiment, the invention relates to the above attachment which especially may be an attachable brush, comprising a connecting piece that can be placed on the handle part neck of the toothbrush handle part. The toothbrush handle part comprises disengageable arresting means for arresting, blocking, and/or braking the drive train part. Advantageously, the arresting means are automatically released when the attachable brush is attached and are transferred to the arrested state when the attachable brush is removed. In the arrested state of the drive train part, the drive motor is automatically switched off.

Abstract: An attachment for an electric toothbrush, including a working head and coupling member mountable on a toothbrush handpiece. The coupling member includes a sleeve-shaped coupling insert with an engagement section for locking with the handpiece. The coupling insert is displaceable relative to the coupling member or an actuating member such that an axial movement of the coupling insert relative to the coupling member or actuating member produces an unlocking/locking movement of the engagement section in a direction transverse to the attachment longitudinal direction. The attachment or actuating member is first moved axially relative to a locked coupling insert until the axial relative movement releases the lock for the coupling insert and the attachment to be separated from the toothbrush handpiece.
