Abstract
An electric toothbrush includes a handpiece and a mountable attachment. The attachment includes a working head and a coupling member which is joined to the working head and connectable to the toothbrush handpiece by positive and/or frictional engagement. The attachment can be an attachment brush for dental cleansing, or for interproximal cleaning devices, such as gum massage heads or other attachment tools for performing similar tasks in the oral cavity. The coupling member is braced against the toothbrush handpiece, to provide a low to zero-play connection which accommodates production tolerances. At least one pivot lever or toggle joint is provided for clamping the coupling member upon the toothbrush handpiece.
Claims24
An attachment for an electric toothbrush, comprising:
- a working head;
- a coupling member joined to the working head, and detachably connectable to a toothbrush handpiece by at least one of positive engagement and frictional engagement;
- and
- at least one pivot lever configured to clamp the coupling member upon the toothbrush handpiece;
- wherein a lever actuator is provided that is axially movable relative to the coupling member longitudinal direction, the actuator including a follower element that engages the toothbrush handpiece on plugging the attachment onto the toothbrush handpiece, and being operatively associated with the lever by connecting means in such a way that, on plugging on the attachment, the lever actuator becomes displaced axially, thereby moving the lever into its clamping position.
