Structure for Fabricating Jewelry Parts or Wrist Watches

The invention relates to a structure for fabricating jewelry parts or wrist watches with at least one gem stone or a watch, as well as a piece of jewelry with a gem stone and/or a watch.

Conventionally pieces of jewelry are so fabricated from gem stones, that the latter, no matter whether they are precious or semiprecious stones, are directly fixed to a support, such as e.g. a gold ring or hoop, or are arranged between individual chain sections. Thus, the piece of jewelry has its shape and color fixed once and for all.

Modern wrist watches are also generally not interchangeably connected to a watch strap. However, of late, a wrist watch has been developed, in which a watch case can be associated, as desired, with different watch straps and can be given decorative ring elements. However, this merely provides a possibility of using watch straps of different form and color with said fixed associated cases.

The object of the present invention is to structure of the aforementioned type of jewelry parts, which are randomly interchangeable and combinable, whilst using only one fixed basic element. Use is in particular to be made of the possibilities which are described in the method for fabricating semiprecious stone-like gems as a substitute for semiprecious stones according to Swiss patent application No. 6954/83-5.

The above object is achieved by structure of the aforementioned type in which the gem stone or parts of the watch are associated with a holding element and are interchangeably joined thereto together with a support.

The support forms a basic fitting which depends on the intended use and the special requirements of the wearer. Thus, as an individual element, the support can e.g. be inserted in a ring. If the wearer requires for her clothing a particular color or shape combination of the gem stone, then she can place it together with the corresponding holding element on the support. When changing the clothing, it is also possible for her to correspondingly change the gem. The same also applies for ear clips, cufflinks, etc, as well as for bracelets and necklaces, where e.g. several such supports are provided on a band. Thus, the wearer can in a simple manner assemble or make up a piece of jewelry and can modify it as a function of her taste.

The same inventive principle applies when using a watch as a jewelry item. It is then possible to change watch glasses of different shades, as well as the complete upper part of the case, which can once again be in the form of a piece of jewelry. It is also possible to surround a watch with a plurality of gems. There are so many possible variants, that only a few examples can be given here. In addition, this building block system can be extended at random, whilst once again taking account of individual taste.

FIGS. 1 to 4 show as examples of jewelry items produced according to the structure and method of the present invention, respectively, a bracelet, a necklace and wrist watches. Each piece of jewelry essentially comprises supports 1, which in the present case are assembled end-to-end to form a strap or band section 5, a holding element 2, also with different configurations, and the actual gem stone 3 or the watch glass 4 covering a not further shown clockwork.

In FIG. 2 the support 1 constructed as strap portion 5 is for the purposes of illustration only partly covered gems 3. The individual supports 1 of strap part 5 are separated according to FIG. 5 by desired bending points or lines 6, so that the strap part 5 can e.g. be formed into a bracelet or watch strap, as shown in FIGS. 7 to 9. The desired bending lines 6 can be formed in that the individual supports 1 are separately fixed to a flexible band. However, it is also possible to provide separate connecting pieces for the individual supports 1.

Examples of different gem stones 3 are shown in FIG. 6.

According to FIG. 7 a strap part 5 formed from individual supports 1 is made into a watch strap, a clasp 7 interconnecting the two ends of the strap part 5. In FIG. 8 the strap part 5 according to FIG. 7 already has the holding elements 2 and watch glass 4. FIG. 9 shows the start of covering a strap part 5 with gems 3 carried by holding elements 2.

FIG. 10 shows a different arrangement of the supports 1 for rings, ear clips, cufflinks, etc. Only a single support 1 is required and is fixed to jewelry parts 8 or fixing parts 9, 10. According to FIGS. 11 and 12 said supports 1 are provided with differently shaped holding elements 2 adapted to the particular pieces of jewelry 3.

FIG. 13 shows those parts which, according to the invention, are assembled to form a piece of jewelry. Support 1 is constructed here as a rail element and has a cross-sectionally dovetailed rail 11, whose shape corresponds to a groove 12 in holding element 2. The latter is also U-shaped with a base part 13, as well as two legs 14 at an angle w to base part 13. From base part 13, groove 12 once again forms a dovetail-like tongue 15, which fits into a channel 16 of gem stone 3. The side walls 17 of gem stone 3 are adapted to the shape of holding element 2. Gem 3 can be fixed, e.g. bonded to holding element 2. Channel 16 can also have a shape adapted to tongue 15 with undercuts, so that gem 3 is positively secured.

Holding element 2 is maybe nonepermanently mounted on support 1 and can at any time be interchanged with a differently shaped holding element and/or a different gem 3. FIG. 14 shows the unit of an assembled jewelry part 18 formed from support 1, holding element 2 and gems 3. In the embodiment according to FIG. 15 a groove 19 is shaped into support 1a. A tongue-like strip 20 fits into said groove 19 and is placed on the underside of the U-shaped holding element 2a. The legs 14a of the holding element are at an angle w of approximately 90.degree. to the base part 13a, so that the gem 3a can be bonded or clamped in said holding element 2a. The assembled jewelry item 18a comprising support 1a, holding element 2a and gem 3a is shown in FIG. 16.

According to FIG. 17 a holding element 2b, which is in this case a mount for a not shown clockwork or a watch case base is mounted on a rail band forming support 1b. This mount 2b can be in different forms, some of which are shown in exemplified manner in FIG. 18. A case frame 22 is then placed on mount 2b and a watch glass 23 engaged thereon. The watch glass 23 can also have a shade appropriate for the gems mounted on rail band 1b and is correspondingly changed on changing the gems.

The upper representation in FIG. 17 shows the assembled watch 24, which then only has to be engaged on rail band 2b. The result is a wrist watch, in the manner shown in FIG. 8, the remainder of the band or strap being provided with gems in holding elements.

According to the wrist watch embodiment of FIG. 19, the support comprises a rail element 27, which is placed on an elastic endless band or strap 26. For this purpose, rail element 27 has a channel 28 and a rail beam 29 embraced in the use position by an undercut groove 30 form on a watch case 31. Watch case 31 is embraced by a spring clip 32. There is also a watch glass 23a and a case frame 22a around which pass edge-protecting wires 33. This case frame determines the external shape of the watch, different possibilities being shown in exemplified form. The case frame 22a is also interchangeably constructed, and for this purpose is provided with an inner annular slot 35 that engages projections 36 on watch case 31. Watch glass 23a also has a circular collar 37, which engages in a locking groove 38 in what case 31.

Case frame 22a also covers the spring clip 32, but forms a movement zone 39 for the spring clip 32. Spring clip 32 is fixed via feet 40 to a bearing collar 41 of watch case 31.

The arrangement of the spring clip for fixing the complete watch in particular serves its function when the rail elements 27a, together with the endless band 26 are joined in the manner of a zipper, as shown in FIG. 20. Round heads 43 then engage over the rail beams 29. This "zipper" can be injection molded in one piece from plastic.

If a watch 24a is now mounted on said zipper, the spring clip 32 is raised due to the round head 43 and as shown in FIG. 21. After round passing over the head 43 spring clip 32 drops downwards into the closed position shown in FIG. 22. For this purpose, the spacing s between the rail elements 27a or the width b of a rail element beam must be dimensioned so that the spring clip 32 closingly surrounds one or more rail elements 27a.

According to FIG. 23 similar parts are used for fabricating a decorative strap as for fabricating a watch. Once again a rail element 27 is connected to an endless band or strap 26. The rail element 27 and endless band 26 can be held together by a hinge fastening 44, which comprises a clip part 45 and hinges 46 about which rotate two adjacent hinge fastenings 44. FIG. 24 shows a hinge closure 47, with which two hinge fastenings 44 can be coupled together. The holding element is in this case two guide plates 48, which are held together by spring clip 32 with feet 40, a gap 49 being formed for receiving rail element 27. The spring clip 32 is also shown in plan view in FIG. 23. Gem 3 is also located in the frame of spring clip 32 and is optionally fixed to the guide plates 48 or is held in clamping manner by spring clip 32. FIG. 25 shows two use positions of spring clip 32, the function of the latter being described relative to FIGS. 21 and 22.
