Abstract

The ring has an outer ring (3) that is pivotably stored on an inner ring (1). The inner ring has two pins (2) that are diametrically and radially opposite to each other. The outer ring has an annular groove for rotational storage of the outer ring on the inner ring. The pins are storable in the groove for coaxial rotational movement of the outer ring on the inner ring. An intermediate ring provided between the inner and outer rings is rotatably stored in the groove in a coaxial manner, where the inner ring with pins is tiltably stored in the intermediate ring.

Description

The invention relates to a jewelery ring according to the preamble of claim 1.

This jewelry ring can be a finger ring or a bangle. Also, the jewelry ring may be part of an earring.

A jewelry ring of the type specified is from the DE 203 05 328 U1 known. The basic principle of this jewelry ring is that an outer ring on an inner ring is pivotable about both a diameter axis and coaxially rotatable. For this purpose, the inner ring at two diametrically opposite points on pins. Corresponding to these pins, the outer ring has an annular groove around the inner circumferential surface around. In this annular groove, the pins of the inner ring are mounted.

The problem with this known jewelry ring is the storage of the pins in the annular groove. This can lead to tilting of the pins in the annular groove over time due to the punctual overlays. Also, the annular groove can become clogged with dirt over time, which can adversely affect the smooth running of the coaxial rotational movements of the outer ring on the inner ring.

The invention is therefore based on the object to improve the rotary bearing of the outer ring on the inner ring in a jewelry ring of the type specified.

The technical solution is characterized by the features in the characterizing part of claim 1.

The basic idea of the invention lies in an additional intermediate ring, which is provided between the inner ring and the outer ring. Since this intermediate ring rotates in the annular groove of the one ring and therefore lies over a large area in this annular groove, this eliminates the risk of tilting. This means that the intermediate ring in the annular groove can also rotate in the long term. Moreover, since in the or on the intermediate ring that ring is pivotally mounted with the pins, beyond the pivoting movement of the outer ring with respect to the inner ring is always guaranteed properly. Overall, the rotary bearing of the outer ring is thus improved on the inner ring.

According to the embodiment in claim 2, the pins are preferably arranged on the outer circumferential surface of the inner ring, while the annular groove is formed around the inner circumferential surface of the outer ring around. Of course, the reverse way is possible, namely, that the pins on the outer ring facing radially inward and that the inner ring around the outer circumferential surface around the annular groove.

A preferred embodiment proposes according to claim 3, that the intermediate ring is mounted by means of a ball bearing in the annular groove of the outer ring. In this case, this ball bearing has at least three balls. Through this ball bearing ensures that the intermediate ring can easily rotate in the outer ring. In particular, thereby the ease of rotation is increased. Structurally, this ball bearing is preferably realized in that around the outer periphery of the intermediate ring part spherical recesses are formed, in which the balls are freely rotatable. Otherwise, the balls are then still stored with their surface in the annular groove of the outer ring. Of course, a reverse construction is possible, namely that the balls of the ball bearing are mounted in the inner circumferential surface of the outer ring (and also in part spherical recesses) and that then the radially inwardly directed surface of the balls are mounted in the peripheral annular groove of the intermediate ring.

Preferably, according to the embodiment in claim 4 in the gemstones are rubies or sapphires.

The Fig. 1 to 4 show a first embodiment and the FIGS. 5 and 6 a second embodiment of a jewelry ring.

The jewelry ring of the first embodiment in the Fig. 1 to 4 has an inner ring 1, as he can be plugged for example on the finger of a hand. This inner ring 1 has two diametrically opposed pins 2, which project radially and define an axis of rotation with respect to their connecting line.

The jewelry ring further comprises an outer ring 3, which is rotatably mounted on the inner ring 1 about the common center axis. For this purpose, the inner circumferential surface of the outer ring 3 has an annular groove 4.

For the pivot bearing an intermediate ring 5 is provided. This is rotatably mounted in the annular groove 4 of the outer ring 3. In the intermediate ring 5, the inner ring 1 is further mounted pivotably with its two pins 2.

The operation is as follows:

The outer ring 3 can perform two movements on the inner ring 1:

On the one hand, the outer ring 3 can be rotated on the inner ring 1 with respect to the coaxial center axis of the two rings, namely endlessly around the entire circumference. To For this purpose, the intermediate ring 5 performs in the annular groove 4 of the outer ring 3 from a rotational movement and takes over the pins 2, the inner ring 1 with.

On the other hand, the outer ring 3 can be pivoted on the inner ring 1 with respect to the two pins 2 as a rotation axis laterally in both directions, as in Fig. 4 is recognizable. It shows in Fig. 4 the middle representation shows the basic position, while the two outer representations show the pivoting in one direction and in the other direction.

The FIGS. 5 and 6 show a second embodiment of a jewelry ring, which is based on the basic principle of the first embodiment of Fig. 1 to 4 based. The structural extension with respect to the first embodiment example is that in addition a ball bearing is provided consisting of three balls 6, between the intermediate ring 5 and the outer ring 3. For this purpose, the outer peripheral surface of the intermediate ring 5 evenly distributed three part-spherical recesses, in which the balls are 6. These balls 6 are gemstone balls, in particular rubies or sapphires. These balls are still in the annular groove 4 of the outer ring. 3

The operation is as follows:

According to the first embodiment in the Fig. 1 to 4 the outer ring 3 is rotatable both coaxially on the inner ring 1 rotatable and with respect to the axis defined by the pins 2 axis. However, by providing a ball bearing of at least three balls 6 between the intermediate ring 5 and the outer ring 3, this facilitates the coaxial rotational movement of the outer ring 3 on the intermediate ring 5.
