Description

The invention relates to a finger ring with an inner ring and an outer ring surrounding the inner ring, wherein the inner and outer rings are movable relative to each other and have an imaginary central axis.

There are already finger rings in which the inner and outer rings can move relative to each other, in that they can both rotate relative to each other around the common, imaginary central axis. For this purpose, the inner and outer rings are connected to each other, for example, via roller bearings, which allow circumferential rotation but which fix the rings in other directions relative to each other. On the one hand, such finger rings allow applications on the outer ring to be rotated with it, so that the ring has a different appearance depending on the position of the outer ring, and on the other hand, they allow the popular subconscious "playing" with the ring. However, such finger rings have the disadvantage that they are very thick due to the two coaxial rings and cannot always offer the desired wearing comfort.

The invention creates a finger ring in which wearing comfort is significantly improved.

This is achieved in a finger ring of the type mentioned above by mounting the outer ring on the inner ring in such a way that the rings are also relatively

can be rotated relative to one another about an additional axis that is essentially perpendicular to the central axis. When the finger ring according to the invention is put on, the outer ring can rotate sideways to the inner ring when viewed from the finger onto which the ring has been put on, and thus cling to the adjacent finger or fingers. This creates excellent wearing comfort, and the ring also adapts to every movement, because the outer ring gives way to pressure from the outside due to its pivoting ability.

The preferred embodiment provides that the outer and inner rings are also rotatable relative to each other about the imaginary central axis, i.e. there are two independent axes of rotation, namely the central axis and the additional axis, which are preferably perpendicular to each other, although there can of course also be small angular deviations.

Usually, bearing extensions are provided which positively connect the two rings and define the additional axis.

Although the bearing extensions could extend from the outer ring into the inner ring, the preferred embodiment provides that the bearing extensions extend radially from the inner ring and extend into a recess on the inside of the outer ring. This has the advantage that even when rotating about the additional axis, the visible sections of the outer surfaces of both rings are smooth and the bearing remains invisible.

The receptacle is preferably a circumferential groove which, together with the bearing extensions, defines both the central axis and the additional axis.

Pins inserted into holes in the inner ring are provided as bearing extensions. These are secured in the holes, which is preferably done by soldering.

Rotation around the two axes is facilitated if the free ends of the bearing processes, i.e. the ends that protrude from the ring to which they are attached, are rounded.

Preferably, at least one of the rings has a convex outer surface, according to the preferred embodiment even both rings. Especially if the inner ring has a convex outer surface, the gap between the two rings can be kept very small. This gap must be large enough to allow rotation about the additional axis. The outer surface of the inner ring can preferably have a spherical surface shape.

Further features and advantages of the invention will become apparent from the following description and from the following drawings, to which reference is made. In the drawings:

- Figure 1 is a perspective view of the finger ring according to the invention with the outer ring not yet pivoted about the additional axis,

-Figure 2 shows the finger ring according to the invention with separate inner and outer rings,

- Figure 3 shows the finger ring according to the invention with the outer ring pivoted, approximately in the position in which the ring is worn, and

- Figure 4 shows the finger ring according to the invention with the outer ring rotated almost 90° around the additional axis.

Figure 1 shows a finger ring 1 having an inner ring 3 and an outer ring 5, wherein the two rings 3, 5 consist of separate parts, as shown in Figure 2.

The outer ring 5 has on its inner side a circumferentially closed groove 7 which forms a receptacle for pins 9. The pins 9 are inserted into diametrical bores in the inner ring 3, fastened by soldering and protrude from the convex outer surface 11 of the inner ring 3, wherein the free, radially outwardly projecting ends of the pins 9 are spherically rounded.

The pins 9 protrude into the groove 7 and form bearing extensions.

The assembly of the outer ring 5 to the inner ring 3 is carried out by

State in which at least one pin 9 does not yet protrude from the outer surface 11, the rings are inserted into one another and the at least one pin 9 is pressed outwards in order to penetrate into the groove 7. This pin 9 is then soldered.

The two rings 3, 5 each have an imaginary central axis A (rotation axis). In the position shown in Figure 1, when the rings 3, 5 are exactly aligned with each other, the central axes A coincide. The two rings 3, 5 are arranged concentrically with each other.

The outer ring 5 can be rotated relative to the inner ring 3 about the central axis A, whereby the pins 9 rotate in the groove 7 during this rotation process.

The pins 9 also define an additional axis, called additional axis Z, which preferably runs perpendicular to the central axis A and preferably intersects it. However, slight angular deviations and a small distance between the axes A, Z are possible and may also be desired to improve wearing comfort.

The rings 3, 5 can be rotated around the additional axis Z without stopping or can be pivoted slightly, which is achieved by the pins 9 rotating around their own axis in the groove 7.

This rotation allows the inner ring 3 and outer ring 5 to pivot in an X-shape relative to one another, as shown in Figure 3, when pressure is exerted on the outer ring 5 from the outside, e.g. by the adjacent finger. This results in great wearing comfort, particularly when the outer ring 5 also has a conical outer surface 13, as shown.

The rotations around the axes A, Z can also be superimposed.

In Figure 4 it can be seen that the outer ring 5 can not only be easily pivoted relative to the inner ring 3, but that rotations of more than 360° are possible.
