In the first embodiment according to FIG. 1, the back massaging device 1 according to the invention comprises two spherical massage bodies 2 with a diameter of 5 to 10 cm, which are arranged displaceably and rotatably on a straight and smooth one-piece bar 3 with a circular cross section. The rod 3 has a length of 15 cm to 50 cm and a diameter of 1 cm to 3 cm. Each of the two massage bodies 2 consists of an elastic plastic foam, preferably an ecologically harmless material, and has a through hole extending along an axis of symmetry of the massage body 2. Through these through holes of the massage body 2, the rod 3 is guided, so that the rod 3 protrudes through the massage body 2 passes. The diameter of the through holes of the massage body 2 is chosen smaller than the diameter of the rod 3, so that the massage body 2 are arranged non-positively on the rod 3 and the massage body 2 does not change their position on the rod 3 during the massage process unintentionally. By applying force, the massage body 2 can be moved by overcoming the frictional connection along the rod 3 and twisted around the rod 3. In particular, the massage bodies 2 can be pushed completely down from the rod 3 and replaced by another pair of massage bodies 2 having a different diameter and / or a different hardness. For better distinctness each associated pair of massage bodies 2 is colored in a different color. Thus, a large variability of the back massaging device 1 is possible.

With the back massager 1 according to the invention, the entire back area can be massaged. The user can be leaned against a door or wall, the back massager 1 being clamped between the door and the back. The rod 3 of the back massager 1 extends in the horizontal direction. By up and down movement of the user creates a rolling motion through which a massage effect is achieved. By changing the foot distance to the door or wall, the contact pressure generated by gravity on the massage body 2 varies. This allows the user to vary the intensity of the massage very easily. Alternatively, the user can use the back massager 1 while lying down. For this purpose, the user can position the back massager 1 between his back and the floor and achieve a massage effect by corresponding horizontal forward and backward movements.

In the second embodiment according to Figure 2, the rod 3 is deviating from the first embodiment constructed in several parts. Here, the rod comprises two outer parts 3X, on each of which a massage body 2 is arranged, and a central part 3Y, which connects the two outer parts 3X. The distance between the two massage bodies 2 can be changed, for example, by replacing the middle part 3Y with a shorter or longer replacement part or by removing the part 3Y between the two outer parts 3X so that the two outer parts 3X are directly connected to each other. Accordingly, the rod 3 comprises at least two parts 3X, 3Y, which can be arranged and connected in different configurations in order to adjust the distance of the massage body 2 to each other. The connection between the parts 3X, 3Y of the rod 3 can be accomplished for example by a uniform plug and / or locking connection.

In the tenth embodiment according to FIG. 10, which is substantially based on the ninth exemplary embodiment, the back massaging device 1 comprises a strand-like and flexible tether 4, both ends of which project in each case at one of the two outer ends of the tube 3 and by a static locking device or connecting device 6 are connected. The tether 4 is passed over the shoulders of a user to a variable locking device 5, which the user can hold in his hands during the massage process. By moving and locking the variable locking device 5 relative to the tether 4, the user can releasably connect two spaced apart portions of the tether 4 with each other and thus adjust the free length of the tether 4 between the two force application points on the rod 3. This allows the user to adjust the position of the back massager 1 at his back and the distance of the variable locking device 5 of his body as desired. Of the variable locking device 5, the ends of the tether 4 are guided to a static locking device or connecting device 6 connecting the ends. In the fifth or tenth embodiment, the variable locking device 5 can be replaced by a sliding ring, through which two spaced apart portions of the tether 4 are slidably passed therethrough. Instead of the static locking device or connecting device 6, two ends of the tether 4 can be knotted together.

Further advantageous embodiments result from any combination of the features disclosed herein.
