Description

[Explanation]
The present invention relates to jewelry. An opening is provided in the main body of the jewelry, in which a decorative element, in particular a precious stone or a decorative stone, is accommodated, and the decorative element is contained in the opening of the main body of the jewelry containing the decorative element. A support for the element is formed, thereby defining a depth of insertion of the decorative element into the opening of the body of the jewelry, and thereby at least selectively supporting the lower edge of the decorative element The jewelry article includes a fixing element extending along at least a part of the circumference of the opening. The invention also relates to a method for producing such a jewelry article, in particular a ring. The jewelry body is provided with an opening in which a decorative element, in particular a precious stone or a decorative stone, is accommodated. After the first step of the method, the opening provided in the body of the jewelry has a diameter smaller than the diameter of the decorative element inserted into the opening, and in the next step, An upper portion of the opening having a diameter greater than or equal to the diameter of the decorative element is formed, so that the upper portion having the diameter of the opening and the lower portion having the small diameter of the opening; During which a transitional portion is formed which functions as a support for the decorative element, the decorative element being inserted into the opening and set on the support, so that in the next step the gemstone The material of the body of the article is eroded in the area surrounding the opening, and the eroded material is brought into the decorative element housed in the opening of the body. The invention further relates to a tool particularly suitable for carrying out such a method.

  Gemstones in which decorative elements, in particular precious stones, are known in the openings. The disadvantage of the known jewelery is that the decorative elements are mostly arranged on the surface of the jewelry body, and the decorative elements housed in the jewelry body do not have a spatial appearance, as a generally flat decoration. This is the point that is observed.

  From British Patent Publication (GB) 20849855, jewelry and methods of the kind described above are known. A person who looks at a jewelery manufactured by a known method, the decorative element inserted in the opening of the jewelery body is designed by the appropriate design in the area of the jewelery body surrounding the jewelery with facets. It should have the impression that it has a higher optical presence than without it. Therefore, the illusion of larger and more optically present decorative elements should be evoked by the method described above. For this purpose, this British document suggests that: That is, to produce facets, the body of the jewelry is fixed in a press with a facet forming punch and a press bed acting against it. In order to fix the jewelry in place in the press, the body of the jewelry shall have a circular groove concentric with the opening and cooperating with the ribs of the press bed on the surface facing the opening. ing. Then, the compression force acts on the facet forming punch and the material of the jewelry body surrounding the opening is cold worked so that a force directed towards the decorative element contained in the opening acts on this material. In this way, this material is displaced towards the decorative element and forms a fixing element for the jewelry.

  In other jewelery in which the decorative element is provided deeper in the opening of the jewelery body, the disadvantage is that the jewelery must be fixed in the opening by the fixing procedure. This measure has the disadvantage that, in particular in the case of precious stones, the decorative element is scratched by the glue used or is unstablely fixed only in the opening of the body in the case of “loose fixing”. This is particularly disadvantageous when expensive precious stones are used as decorative elements.

  The object of the present invention is to ensure improved support and improved optical presence, even when the decorative element is housed in the opening of the body as well as in appearance. It is to further develop the jewelry and to create a method for producing such a jewelry and a tool particularly suitable for carrying out this method.

  This object is achieved by the jewelery according to the invention. In this case, the fixing element widens the opening of the body of the jewelry in a region surrounding the opening and then stabilizes the material eroded from the region surrounding the opening of the body. The fixing element acts at least selectively on the upper edge of the decorative element, and the region surrounding the opening of the body of the jewelry is at least partially chamfered.

  One advantageous development of the invention is that the fixing element is formed to extend substantially along the entire circumference of the opening. Such a measure has the advantage that a special safe support for the decorative element is thereby formed in the opening of the body of the jewelry.

  The method according to the invention allows the erosion of the material in the region surrounding the opening to be carried out by widening the region surrounding the opening and the fixing element to the decorative element is It is made of a material that has been eroded. As a result, the upper edge of the decorative element is at least selectively acted on by the fixing element so formed, and in this way the decorative element is fixed in place in the opening.

  An advantageous different development of the method according to the invention is that the fastening element is formed to extend substantially along the entire circumference of the opening of the jewelry article. Such an implementation of the method has the advantage that a particularly safe support for the decorative element is thereby achieved in the opening. A further advantageous development of the method according to the invention is that at least one corner of the decorative element is provided with anti-twisting means, in particular a seat.

  A tool that is particularly suitable for producing the jewelry according to the invention is advantageous in that it comprises a cylindrical or conical tool body. The tool body has at least one spreading element arranged in its front part. This portion has a widened area extending obliquely with respect to the outer surface of the tool body. The tool body has an opening for receiving the decorative element.

  The measure according to the invention creates, in an advantageous manner, jewelry, a method that is particularly advantageous for its manufacture, and a tool that is particularly suitable for carrying out this method. The jewelery according to the invention has the advantage that a safe support for the decorative element inserted in the opening of the body of the jewelery rather than apparently is also provided in the opening. Another advantage of the countersunk inserts of the decorative element made possible by the measures according to the invention is that the surface of the jewelery can be treated (ground, ground, stoned, etc.) without problems. In this case, the decorative element housed in the opening of the jewelry is not damaged, and the decorative element housed in the opening of the jewelry does not disturb the treatment.

  Another advantage of the measure according to the invention is that the decorative element housed in the opening is improved by erosion by a spreading tool on the material of the body of the jewelry in the region surrounding the opening. The optical existence is given. Furthermore, one advantage of the present invention is that the described method is not limited to the special form of the decorative element. The method according to the invention rather allows a safe insertion of the decorative element into an essentially circular opening by means of a plurality of different cuts.

Further advantageous developments of the invention are the subject of the dependent claims.
Further details and advantages of the invention are given in the embodiments described below with reference to the drawings.

  FIG. 1 shows a cross section of a jewelery 1 with a body 2, in this example a ring 1 ′. If this ring 1 'is a ring bar, its surface 3 has at least one opening 4, into which a decorative element 5 of diameter D is inserted. In this example, as is apparent from FIGS. 3 and 4a to 4e, the opening 4 is a through-hole, whereby the opening 4 can be formed as a blind hole.

  It is also possible for the jewelery 1 to be designed as a pendant, as an earring, as a chain ring, or as a decorative element for a watch, watch, or watchband, etc., not as a ring 1 '. Therefore, the term “jewelry” is to be understood in its broadest sense and includes not only the finished jewelry, but also parts of such items.

  The decorative element 5 is preferably a precious stone, but it is also possible to use a decorative stone and each decorative element. Thus, the term “decorative element” should also be understood in its broadest sense.

  As can be seen in particular in FIG. 1, in the described jewelry 1, the decorative element 5 is provided not only in appearance but also in the body 2 of the jewelry, but the decorative element 5 can be seen in FIG. Further, it is provided away from the surface 3 of the main body 2 of the jewelry 1, that is, buried in a countersink.

  In order to be able to securely fix the decorative element 5 in the opening 4 (this means that the decorative element 5 is set in the main body 2), the opening of the main body 2 of the jewelry 1 4 is formed as seen in FIGS.

  As shown in FIG. 4 a, in the first step, an opening 4 formed as a through hole in this example is applied to the body 2, and the diameter of the opening 4 is smaller than the diameter D of the decorative element 5. To be. This easily arises from a comparison of FIGS. 4a and 4b.

  In a subsequent step, schematically shown in FIG. 4b, the upper part 4 'of the opening 4 of the body 2 of the jewelry 1 is enlarged to a diameter d', for example by scooping or milling. This diameter d 'is at least equal to the diameter D of the decorative element 5, but is preferably slightly larger. This is because the decorative element 5 can be brought into the upper part 4 ′ of the opening 4, as will be described later (see FIG. 4 d).

  Since the lower part 4 ″ of the opening 4 is left unchanged, it has a diameter d. For this reason, between the lower part 4 ″ of the diameter d and the upper part 4 ′ of the diameter d ′, A transition portion 6 is formed. As a result, the transition portion 6 is preferably formed in a conical shape. In general, a step transition 6 is also possible.

  As best seen in FIG. 4 d, the transition part 6 forms a support 7 for the decorative element 5 inserted in the opening 4. For this reason, the decorative element 5 cannot be inserted into the opening 4 deeper than that. The depth of localization of the transition part 6 in the opening 4 of the body 2 of the jewelry 1 is therefore dependent on the desired insertion depth of the decorative element 5 into the opening 4. Depending on the shape of the decorative element 5, the support 7 supports the lower edge 5 ′ of the decorative element 5 at least selectively, preferably over the entire circumference, and thus supports the decorative element 5 in the opening 4. Secure to the bottom of the.

  In the subsequent step, the seat 8 is provided in the transition part 6, as seen in FIG. 4c. This seat acts as a protection against twisting of the decorative element 5 in one of the subsequent steps. However, depending on the shape of the decorative element 5 and the execution of the subsequent steps, the seat 8 can be omitted.

  After the opening 4 is formed as described above and the decorative element 5 is inserted into the opening 4 and set on the support 7 formed by the transition part 6, in the body 2 of the jewelry 1 A fixing element 10 is formed which serves as a mounting base for the decorative element 5 and fixes the decorative element 5 in a fixed position in the upward direction as seen in FIGS. 4d and 4e. In this case, this fixing element 10 acts on the upper edge 5 ″ of the decorative element 5. In the process shown in FIG. 4d, the material of the jewelry body 2 is shown in a suitable tool W, preferably in FIG. And is acted on in the region 11 surrounding the opening by spreading with a tool described below.

  This material erosion is preferably carried out by a spreading procedure, and the material of the body 2 eroded from the region 11 is eroded by the spreading movement and then transported towards the decorative element 5 where it is re-stabilised. As can be seen in FIGS. 3 and 4, the fixation element 10 is thus formed by a material that has been eroded from the region 11 and re-stabilized directly adjacent to the decorative element 5. By this fixing element 10, the decorative element 5 is at least selectively fixed at a fixed position in the opening 4. The fixing element 10 is preferably formed so as to extend essentially or completely along the entire circumference of the opening 4. A particularly safe support for the decorative element 5 in the opening 4 is then achieved in an advantageous manner. Thereby, in combination with the support body 7, an inlaying base for the decorative element 5 is achieved in the opening 4 of the body 2 of the jewelry 1 in a simple manner, opening the reliable support body of the decorative element 5. Provided in part 4.

  As best seen in FIG. 4e, erosion of the material described above results in a conical region 11 surrounding the opening 4. As a result, in an advantageous manner, the decorative element 5 comes to have an optically existing appearance, although it is housed deep in the opening 4.

  The tool W described only schematically in FIG. 4 is shown in detail in FIG. The tool W comprises a tool body W1 having an interior W2 in which a decorative element is accommodated, as can be seen in FIG. 4d. The tool W is provided with a spread area W5 on the front surface W 'thereof. This widened region is preferably divided into a plurality of segments W3 and is preferably formed so as to be inclined with respect to the outer surface of the tool W1. The shank W6 starting from the tool body W1 allows the driven rotation of the tool W. The presented tool W is not only suitable for carrying out the method described above. It is also suitable for setting round stones according to conventional techniques in an advantageous manner. This is because such decorative elements are spread more deeply than with the prior art. This enhances and enables the quality of this spreading process compared to known tools by making the spreading boundary wider and more reliable than usual. This also improves the optical appearance.
