Description

[0012] 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. 3—decorative Jewel in the cast (section), FIG. 4 is a view of a variant of jewelry; FIG. 5—a variant with the execution of a decorative jewel in a cast (section), FIG. 6—General view of jewelry, view “A” (from FIG. 4) 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 “.sup.5”.

[0013] On the surface of the tide “6,” there is a fabricated longitudinal groove “9” and an annular “10” connected to it (FIG. 2).

[0014] 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”.

[0015] 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”.

[0016] 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).

[0017] 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”.

[0018] 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.

[0019] Decorative Jewel “1” only comes into contact with custom “2”.

[0020] 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”.

[0021] 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).

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.
