ITEM OF JEWELLERY

Abstract

The disclosure refers to jewelry or rings worn on fingers with embedded decorative jewels. The technical problem to be solved is to increase the reliability of fixing the decorative jewel by eliminating its mobility and expanding the jewelry's artistic and aesthetic significance. The piece of jewelry contains a decorative Jewel located in a cast, an annular jewelry part with a bead. On the surface of the bead, there is at least one longitudinal groove and an annular part connected to it. The cast is made hollow with a cylindrical inner surface and may be installed along the inner surface. On the inner surface there is at least one protrusion that may be engaged in the groove of the jewelry part.

Claims

1. An item of jewelry, comprising: a ring-shaped component, wherein the ring-shaped component is provided with a centrally located opening defined by a first main plate and a second main plate axially positioned at a predetermined distance from each other and coupled together by a cylindrical tide; and a third plate that is provided with a centrally located opening, wherein the third plate is attached to the first and second main plates through a fastener so that the third plate is rotatable around an axis of the fastener relative to the first and second main plate; a position lock that keeps the third plate fixed relative to the ring-shaped component when the third plate rotates to a position where the centrally located opening of the third plate coincides with the centrally located opening of the ring-shape component; and a hollow cast installed on the tide and comprising a cylindrical inner surface defining at least one protrusion; wherein the tide comprises a longitudinal groove and an annular groove that communicate with each other, and the cast is installed to the tide by the at least one protrusion reversibly engaged with the longitudinal groove and annular groove.

2. The item of jewelry according to claim 1, wherein the cast comprises a recess in an end surface of the cast that allows a part of the third plate to enter.

DETAILED DESCRIPTION OF THE INVENTION

[0021] The utility model is illustrated by graphic images, where on FIG. 1 shows a general view of the jewelry before changing the cast, and FIG. 2 is a cross-section of the cast, FIG. 3decorative Jewel in the cast (section), FIG. 4 is a view of a variant of jewelry; FIG. 5a variant with the execution of a decorative jewel in a cast (section), FIG. 6General view of jewelry, view A (from FIG. 4).

[0022] The piece of jewelry contains a decorative Jewel FIG. 1 installed in a cast 2 and an annular Jewel 3 (FIG. 2). The piece of jewelry is completed with several interchangeable casts 2 with individual decorative jewels 1. Ring jewel 3, with a central hole, includes two main plates 4, 5 located at a distance from each other and connected between a cylindrical bead 6 with a diameter (FIG. 1). An additional plate 8 with a central hole and thickness is fixed on the main plates, through the fastener 7. The plate 8 is fixed with the possibility of rotation about the axis of part 7 and freely passes between the main plates 4 and plates 5.

[0023] On the surface of the tide 6, there is a fabricated longitudinal groove 9 and an annular 10 connected to it (FIG. 2).

[0024] Cast 2 is made hollow, with a cylindrical inner surface of diameter (FIG. 3). The ratio of diameters provides a clearance fit. On the inner, cylindrical surface of cast 2, at least one protrusion is made with an outer dimension. The protrusion 11 due to the ratio of the dimensions, can move freely in the longitudinal groove 9 and the annular groove 10.

[0025] When two longitudinal grooves, for example, 12 and 13, are made, two annular grooves, 14 and 15, respectively connected to them, are made (FIG. 5). In this case, two protrusions 16 and 17 are made on the inner, cylindrical surface of cast 2 (FIG. 5). Wherein this simultaneous arrangement is ensured: the projection 16 in the longitudinal groove 12 and further annular 14, and the projection 17, respectively, in the longitudinal groove 13 and further annular 15.

[0026] In the end surface 18, cast 2, a recess 19 is made, with a width which is sufficient for the entry of a part of the additional plate 8 into it (FIG. 3).

[0027] In the working position, the additional plate 8 is rotated around the fastener 7 axis. The central holes of plates 4, 5, and 8 coincide. The plate 8 presses cast 2 through the surface 18 in the axial direction. When implementing the technical solution according to paragraph 2, part of plate 8 enters recess 19.

[0028] The main plates 4 and plate 5 and additional plate 8 can be equipped with a lock of their relative position 20 (FIG. 1). The presence of the retainer 20 ensures that the position of the additional plate 8 remains unchanged relative to the main plates 4 and plate 5 in case of accidental loads on the jewelry when it is not positioned on the finger. For example, when a jewelry item falls from an elevation.

[0029] Decorative Jewel 1 only comes into contact with custom 2.

[0030] The piece of jewelry is finished with several removable casts, 21 and 22 (FIG. 7), with individual decorative jewels installed in them. All casts: 2, 21, and 22, are made with identical cylindrical surfaces with a diameter D1 and projections 11.

[0031] When performing the variant with two protrusions 16 and 17 during the assembly of the jewelry, they similarly move in the longitudinal grooves 12 and 13 and then in the annular grooves 14 and 15. The further assembly process is similar to that performed in the presence of one protrusion 11. The piece of jewelry operates as follows (FIG. 1). When implemented under the main claim of a utility model. decorative Jewel 1 is put into cast 2. The folding of the claws of cast 2 ensures adaptation to the actual size of decorative Jewel 1 and its reliable fixation in cast 2. The additional plate 8 is rotated around the axis of the fastener 7 so that its central hole and the central hole of the main plates 4 and plate 5 are separated (FIG. 1).

[0032] Cast, 2 on a cylindrical surface with a diameter D2, is installed on a cylindrical bead 6. The ratio of the diameters of the mating surfaces D2>D1 allows this to be done without difficulty. In this case, the projection 11 is located in the longitudinal groove 9. Cast 2 interchanges along the cylindrical bead 6 until projection 11 coincides with the annular groove 10. After that, the cast is rotated around the axis of the cylindrical bead 6. In this case, projection 11 moves along the annular groove 10. The walls of the annular groove 10 fix the projection 11 from movement along the axis of the tide 6. Fixation of the cast 2 from the exit from projection 11 is provided.

[0033] Then the additional plate 8 is rotated around the axis of fastener 7 until its central hole coincides with the central holes of plates 4 and plates 5. Plate 8 contacts the end surface 18. This additionally protects cast 2 from turning around the axis of protrusion 11 and disconnecting from it. The jewelry now becomes ready to use.

[0034] The working position of plate 8 relative to plate 4 and plate 5 is additionally provided by latch 20. This allows the user to maintain the working position of the jewelry in case of accidental impacts outside of use on the finger.

[0035] When implementing the technical solution under item 2, the assembly procedure fully complies with the previously defined. But when turning off the additional plate 8, its part enters recess 19. In this case, additional fixation of cast 2 from turning on the ledge 11 is carried out.

[0036] The simplicity of the procedure for replacing the decorative jewel 1 in conjunction with custom 2 allows the user to perform it directly while using the jewelry. The presence of interchangeable casts 21 and casts 22 allows them to be replaced within a short duration, even while using the jewelry.

[0037] Thus, the claimed jewelry can now provide a more reliable fixation of the constituent jewels, primarily the decorative jewel 1. When altering it in the jewelry, the need for additional fitting is eliminated, and its quick replacement allows you to expand the artistic and aesthetic significance of the jewelry.

[0038] In addition to rings, the jewelry according to the disclosure may be applied to earrings, bracelets, necklaces, and other jewelries with jewels installed thereon.
