Annular piece of jewelry having movable coaxial ring elements

1. An annular piece of jewelry with a plurality of coaxial ring elements connected to each other and moveable in relation to each other, where the ring elements comprise an inner ring element and two outer ring elements and wherein the inner ring element and the outer ring elements can be moved in relation to each other into various positions, in which the outer ring elements cover different outer circumference surface regions of the inner ring element, and wherein the inner ring element is arranged in an axial direction between the two outer ring elements or between parts of the outer ring elements, wherein the two outer ring elements and the inner ring element are coupled to each other, the two outer ring elements are rotatably attached and fixed in the axial direction with respect to each other and the inner ring element moves in the axial direction due to rotation of one of the outer ring elements.

2. The annular piece of jewelry according to claim 1 , wherein an inner cross section or inner diameter of the outer ring elements or of parts of the outer ring elements is smaller than an inner cross section or inner diameter of the inner ring element.

3. The annular piece of jewelry according to claim 1 , wherein the inner ring element comprises of at least two parts.

4. The annular piece of jewelry according to claim 1 , wherein the inner ring element is held in two axial final positions.

5. The annular piece of jewelry according to claim 1 , including a spacer which is arranged radially inwards from the inner ring element, the spacer holding the two outer ring elements in a predefined axial position.

6. The annular piece of jewelry according to claim 5 , wherein an inner side of the spacer forms a contact surface for a body part.

7. The annular piece of jewelry according to claim 6 , wherein the contact surface is a smooth, generally cylindrical contact surface.

8. The annular piece of jewelry according to claim 5 , wherein the spacer is formed by either at least one inner circumferential surface region of the two outer ring elements or the spacer is formed as a separate element inserted in between the at least one inner circumferential surface region of the two outer ring elements.

9. The annular piece of jewelry according to claim 6 , wherein the spacer is formed by either at least one inner circumferential surface region of the two outer ring elements or the spacer is formed as a separate element inserted in between the at least one inner circumferential surface region of the two outer ring elements.

10. The annular piece of jewelry according to claim 7 , wherein the spacer is formed by either at least one inner circumferential surface region of the two outer ring elements or the spacer is formed as a separate element inserted in between the at least one inner circumferential surface region of the two outer ring elements.

11. The annular piece of jewelry according to claim 1 , wherein the inner ring element is in relation to one of the two outer ring elements axially moveable and non-rotatable and in relation to the other one of the two outer ring elements axially moveable and rotatable.

12. The annular piece of jewelry according to claim 1 , wherein at least one annular or sleeve-like guiding element with a guidance is arranged in radial direction inwards from the inner ring element.

13. The annular piece of jewelry according to claim 12 , wherein the at least one annular or sleeve-like guiding element includes two annular or sleeve-like guiding elements having different guidances.

14. The annular piece of jewelry according to claim 1 , including a toothed ring element arranged in radial direction inwards from the inner ring element which engages an opposing toothed ring element and which can be moved by a rotation of the two outer ring elements together with the inner ring element.

15. The annular piece of jewelry according to claim 14 , including a spring, which counteracts the movement of the toothed ring element in one direction.

16. The annular piece of jewelry according to claim 1 , wherein the inner ring element is connected to the outer ring elements by a pivotable coupling part, which during a movement of the inner ring element in relation to the outer ring elements are pivoted in relation to the inner ring element as well as in relation to the outer ring elements.
