Jewelry ring

Description
The invention relates to a jewellery ring.

Pieces of jewelry, and especially jewelry rings, are not just decorative items, but also mementos and often have a highly symbolic character. A prime example of this is the proverbial wedding ring. To emphasize the symbolic value, rings are often engraved with dates, names or short sentences. For aesthetic and privacy reasons, the inside of the ring band is almost always used for engraving, which ensures that the engraving can only be read by the wearer or with the wearer's permission. However, this had the disadvantage that the engraving could of course only be read when the ring was removed, which is particularly disadvantageous because rings that have been worn for long periods of time are often difficult to take off the finger.

Based on this prior art, it is the object of the invention to create a jewellery ring which offers the possibility of applying an engraving which can only be read with the consent of the wearer, whereby the engraving can also be read when the ring is on the finger.

This object is achieved with a jewelry ring having the features of claim 1.

The jewelry ring according to the invention is made up of two parts, namely an outer and an inner ring element, with both ring elements extending around a common ring axis. The two ring elements can be rotated against each other, with the rotational movement being coupled to an axial movement. This means that when the outer ring element is rotated (the inner ring element is on the finger), the outer ring element rotates against the

inner one is displaced axially. With suitable dimensioning of the ring elements, in particular according to claim 8, it can be achieved that by rotating the outer ring element a part of the outer surface of the inner ring element becomes visible, which is covered by the outer ring element in another position. This part of the outer surface of the inner ring element can be used as an engraving section according to claim 6.

It has also been found that the tactile stimulus that the ring according to the invention exerts on the wearer is so strong that the design according to the invention is also useful if no engravings are provided. Furthermore, instead of or in addition to engravings according to claim 7, one or more decorative elements can also be provided, which are visible or hidden depending on the wearer's preference.

Claims 2 to 5 specify preferred ways in which the coupling between rotation and axial movement can be achieved.

The invention will now be explained in more detail using an embodiment with reference to the figures. They show:

Figure 8: a partially sectioned plan view of the ring of Figure 5 in a first position and

Figure 9: a view of the ring in a second position corresponding to Figure 8.

Figures 1 and 2 show the two ring elements 10, 20. Both ring elements essentially have the shape of hollow cylinder walls. The ring elements are dimensioned so that the outer surface of the inner ring element can slide on the inner surface of the outer ring element 10. A groove 22 is made in the outer surface of the inner ring element 20, which has the shape of a sine wave that rotates twice. A pin 12, which is arranged on the outer ring element 10, engages in this groove 22, see for example Figure 5. If the two ring elements 10, 20 are now rotated relative to one another, they move axially relative to one another, as shown in Figures 3 and 4.

The position of the pin 12, the geometry of the groove 22 and the dimensions of the two ring elements 10, 20, which here have the same axial extent, are selected so that in a first end position (Figure 3) both rings completely overlap. In the second end position (Figure 4) the front part, namely the engraving section 2OA (see Figures 8 and 9) protrudes from the outer ring element 10. In this embodiment, the path between the first and second end positions is a quarter turn, which means that the wearer can make the engraving section 2OA of the inner ring element 20 appear or disappear by means of a quarter turn of the outer ring element 10.

With reference to Figures 6 to 9, we will now once again discuss the structural details of the present embodiment:

Figure 6 shows a cross section through the outer ring element 10. The outer ring element 10 initially has holes through which the pins 12 are inserted and secured after the two ring elements 10,20 have been assembled.

Fastening the pins 12 in the holes provided is particularly easy to achieve by laser welding.

The inner ring element 20 is inserted axially into the outer ring element 10 and then the pins 12 are pushed through the holes provided so that the pins 12 engage in the groove 22 (see Figure 8). After the pins 12 have been welded, the ring is finished. The inner ring element 20 is held captive in the outer ring element 10 and the two ring elements 10, 20 can rotate relative to each other with respect to the ring axis A-A. Due to the shape of the groove 22, the rotational movement is coupled to an axial movement.

In principle, it is of course also possible to arrange the groove in the inner surface of the outer ring element and the pins on the inner ring element. From a production point of view, however, this variant is usually the more difficult one.
