Abstract:
1. A massaging device in the shape of a rod with an essentially cylindrical end element, with a sleeve forming an outer surface of the end element and made of a flexible rubber material and with a drive mechanism for generating a movement on the end element for an oscillating deformation of the sleeve in relation to a longitudinal axis (GL) of the end element radially outward and inward, so that the oscillating deformation takes place along the longitudinal axis (GL) of the end element or in a circumferential direction of the end element, the drive mechanism having a plurality of bearing and support surfaces bearing against the sleeve, which are formed by a plurality of support elements and which are driven by at least one shaft, wherein the support elements are formed by several ball elements arranged along the longitudinal axis (GL), which interact with at least one eccentric section of the at least one shaft generate a progressive stroke movement of the support elements along the longitudinal axis (GL) of the end element, wherein the several ball elements are arranged respectively in one common plane perpendicular to the longitudinal axis (GL) of the end element and form a group of ball elements, which interact with the at least one eccentric section to generate a progressive radial stroke movement of the group of ball elements along the longitudinal axis (GL) of the end element, wherein several spiral shafts are provided for holding a plurality of the ball elements, longitudinal shaft axes (WL) of which, are arranged parallel to the longitudinal axis (GL) of the massaging device and which can be driven synchronously to each other.
