The prior art described previously discloses the manufacture of circular ornaments, in particular rings, consisting of two common side bands which can rotate relative to one another around the common layer to change the decorative shape of the ring or to prevent wear. It is.

The object of the present invention is various.

Some people like to wear jewelry such as rings, bracelets, or pendants that consist of a rotating part to rotate the rotating part with their fingers. It is an object of the present invention to produce ornaments exhibiting these features and to present methods for their preparation.

The ornaments according to the invention are of a known type which consist of inner and outer bands which are installed to rotate about each other about their common axis and have a common side.

An object of the invention consists of an inner ring connected to a thinner end by a shoulder and having a central portion having an outer diameter slightly smaller than the inner diameter of the outer band and an axial width slightly larger than the axial width of the outer band. It is also to obtain circular ornaments with an inner band consisting of one or more lateral rings which are welded to the inner ring and placed in contact with the shoulder and which engage on the thinner end after the outer band engages the center.

According to a preferred embodiment the inner band consists of a central part disposed between two narrow ends connected by two shoulders, the inner bands respectively engaging on the thin ends and each of the inner sides of an adjacent plane with respect to one of the shoulders. It consists of two symmetrical side rings which are arranged in the outer band and have peripheral grooves in the center and are defined between them and welded to the inner ring, the axial width of which is shorter than the distance between the shoulders and whose inner diameter is It is smaller than the outer diameter of the lateral ring and is thus freely rotatable in the groove with the outer band received.

Each lateral ring consists of a groove in its inner circumference, which is installed in an outer band between said lateral rings and which said lateral ring is arranged in a welding bead which can be welded to a central axis.

The first method of making circular ornaments according to the invention consists of the following operations:

Machining an outer band having a constant axial width and inner diameter; An inner ring consisting of a central portion having an axial width slightly larger than the axial width of the outer band and an outer diameter slightly smaller than the inner diameter of the outer band and a thin end connected to the central portion by the shoulder portion Possible; -Machine lateral rings with an inner diameter slightly larger than the outer diameter of the flat side and the thin end; Engage the outer band on the center and then engage the side ring on the thin end until its flat side contacts the shoulder and weld the outer band to the inner ring in this position.

The second method of making circular ornaments according to the invention consists of the following operations:-machining an inner ring consisting of a central part connected to two narrow sides by two shoulders separated by a certain distance; -Machine an outer band with a constant axial width slightly shorter than the distance between the shoulders; -Machine two symmetrical lateral rings each consisting of a flat inner side and an inner peripheral groove; The peripheral groove is placed in a welding paste bead; Inserting the outer band on the center of the center ring, and then putting the two lateral rings on each side of the outer band, respectively, until they are against the shoulders; Introduce jewelry to the welding oven and then remove the jewelry from the welding oven.

The present invention relates to circular ornaments, in particular rings, bracelets or pendants, which consist of two axial bands set up to rotate relative to one another and the person wearing such ornaments pivots the rotating part with the fingers thereon.

The ornaments according to the invention are manufactured without machining the ornaments permanently after they are assembled by machining the ornaments in the shape of rings and sandwiching them together and welding the two outer rings.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an axial sectional view of circular ornaments such as rings and bracelets.

These ornaments consist of two common axis bands: an outer band 1 and an inner band 1 installed so as to rotate about each other about their common axis xx1.

The inner band consists of an inner ring 3 and two axial rings 4a and 4b. The inner ring 3 is composed of a central portion 3a connected to two thin sides 3b and 3c by two shoulder portions 5a and 5b.

3 is an enlarged view showing a part constituting the ornament according to FIG. 1 before being assembled.

The method of industrially producing jewelry according to the first and third degrees consists of the following operations.

The inner ring 3 of the precious metal is machined and consists of a central portion 3a disposed between the two narrow ends 3b and 3c, whereby the central portion is defined by two shoulders 5a and 5b. Connected.

Machining is of high precision, whereby the axial length 1 of the center is the distance separating the two shoulders and is determined to have a very small tolerance of 0.1 mm. The outer diameter of the central portion 3a is also machined with high precision.

The two lateral rings 4a, 4b of precious metal are separated and machined, for example in the form of a quarter of a circle, concentric with the vertical plane of the axis.

The central side of the two lateral rings, the sides facing each other, is the plane perpendicular to the axis xx1.

The inner diameter of the rings 4a and 4b is slightly larger than the outer diameter of the ends 3b and 3c of the inner ring.

The outer band 1 of the precious metal is also machined and has a slightly larger inner diameter than the outer diameter of the central portion 3a of the inner ring and is clearly smaller than the outer diameter of the axial ring.

The outer band 1 is machined with high precision and is defined by two parallel sides L a, l b perpendicular to the axis xx1, whereby the width L ₁ of the band is the axial width of the central portion 3a of the inner ring. slightly smaller than (ℓ)

Peripheral grooves 6a, 6b are machined on the inner surface of each outer ring, which is inserted into a welded paste bead that matches the nature of the precious metal constituting the ring.

The outer band 1 is a simple band of precious metal. The outer band also consists of an ornament made of precious metal gemstones made of metal.

Once the ring is separated and machined, the outer band 1 engages the central portion 3a of the inner ring, which is fitted with a slight tolerance so that the two parts can rotate freely with respect to each other. The two outer rings are then fitted to each of the ends 3b and 3c of the inner ring until they are against the shoulders 5a and 5b. The two outer rings are held firmly with respect to the shoulders by clamps or presses and the jewelry is introduced into the welding oven so that the welding paste placed in the grooves 6a and 6b has an inner ring 3 with one ornament The side rings 4a and 4b are welded on. The side rings 4a and 4b are defined between peripheral recesses on which the outer band is constrained as the inner diameter of the band 1 is clearly smaller than the outer diameter of the side rings 4a and 4b.

The width of the peripheral groove coincides with the axial width 1 of the central portion 3a of the inner ring so that the outer band 1 having a smaller axial width than the width of the groove has two side rings 4a ( It is guided by the side of 4b) and is freely rotatable therebetween.

The method according to the invention as opposed to the previously known method makes it possible to produce ornaments which constitute a rotating outer band without deforming the outer band or the inner band.

The embodiment shown in FIGS. 1 to 3 may be constructed of different colors or different precious metals to give the side rings 4a and 4b a special appearance to the ornament.

In a variant when the inner band consists of one metal it consists of only one side ring 4a while the other side ring 4b is fitted to the inner ring 3. In this case the inner ring being machined consists of a central part 3a which is connected to one of its ends to the thin end 3b by the shoulder part 5a and is connected by the opposite end to a thicker part 4b which is integrated. As shown in Figs. 1 and 3, they are machined externally to have the same shape as the ring 4a in the shape of a quarter circle.

2 shows another embodiment of circular ornaments according to the invention.

Like parts are designated by like reference numerals.

The only difference is the first pair of side rings 7a, 7b defined by the two parallel sides perpendicular to the axis xx1 and the second pair of sides giving the ornament different surface shapes. It consists of rings 4a and 4b.

The inner side rings 7a and 7b are only fitted on the ends 3b and 3c of the inner ring and abut against the shoulders 5a and 5b. These rings define a peripheral groove in which the outer band 1 rotates. The outer side rings 4a and 4b are welded to the ends 3b and 3c of the inner ring and the various parts are assembled.

4 is an axial half sectional view of the third embodiment of the circular ornament according to the invention, which consists of an outer band 1 installed to pivot on an annular mounting table 2. The same parts are denoted by the same reference numerals as the first, second, and fourth degrees.

The annular mount is similar to that of FIG. This mount consists of two side rings 4a and 4b welded on two side ends 3b and 3c of the inner ring, two intermediate rings 7a and 7b and an inner ring 3.

The difference from the embodiment according to FIG. 3 is the fact that the outer band 1 consists of an inner recess 8 defined by a surface in step shape or by a circular inner surface 9. The surface of the outer band in contact with the outer surface of the ring 3a can reduce friction between the two parts and rotate the outer band with very little effort and reduce frictional wear.

In addition, the recess 8 has the advantage of reducing the weight of the precious metal used in the manufacture of the outer band 1 without altering the appearance of the jewelry.
