Abstract

A massaging device in the shape of a rod with an essentially cylindrical end element with a sleeve. The device has a flexible sleeve and a drive element to produce an oscillating deformation of the sleeve.

Claims (4)

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 a single shaft, wherein the plurality of support elements are formed by circular disk-shaped jaw elements adjoining each other along the longitudinal axis (GL), which interact with at least one eccentric section of the single shaft to generate a progressive stroke movement of the plurality of support elements along the longitudinal axis (GL) of the end element, wherein each of the circular disk-shaped jaw elements is a single element that maintains a constant diameter during movement and has an elongated oval drive hole enclosing a center of each of the circular disk-shaped jaw elements for holding the single shaft and each of the circular disk-shaped jaw elements has several elongated guide holes extending parallel to one another and the elongated oval drive hole extends in a plane perpendicular to the several elongated guide holes and arranged parallel to the longitudinal axis (GL), the circular disk-shaped jaw elements being guided by inner surfaces of the several elongated guide holes, wherein the massaging device moves in a snake-like massage movement.

2. The massaging device according to claim 1 , wherein the at least one eccentric section extends parallel or approximately parallel to the longitudinal axis (GL) of the massaging device at least over a partial length of the single shaft.

3. The massaging device according to claim 1 , wherein the at least one eccentric section extends at an angle to the longitudinal axis (GL) of the massaging device at least over a partial length of the single shaft.

4. The massaging device according to claim 1 , wherein turning the single shaft in interaction with the inner surface of the drive hole results in a displacement of the respective jaw element in a plane extending perpendicular to the longitudinal axis (GL) of the massaging device.
