Attachment for an oral care device handle

Abstract

An oral care device attachment for being coupled to an oral care device handle having an essentially cylindrical drive shaft coupling end. The attachment has an outer attachment tube having a coupling end for being detachably secured at a housing of the device handle. A carrier is mounted for driven motion at the outer attachment tube. A motion transmitter is disposed inside the outer attachment tube and has a first end coupled with the carrier and a second end arranged for coupling with the essentially cylindrical drive shaft coupling end. The second end has a coupling unit having a top plate and at least one at least partly deformable and essentially cylindrical wall element extending from the top plate, or at least two elastic or deflectable wall elements extending from the top plate, respectively. Each of the elastic or deflectable wall elements extends over a portion of a virtual receiver cylinder, so that an essentially cylindrical receiver receptacle is defined by the top plate and the one at least partly deformable essentially cylindrical wall element or by the top plate and the at least two elastic or deflectable wall elements.
