Description

The invention relates to jewelry, in particular to rings or rings worn on fingers having integrated movable decorative elements. It can also be used to wear as brooches, clips and other jewelry.

Known jewelry with movable decorative elements, moving, mainly rotating, under the influence of special drives. In the described jewelry (patent DE No. 351414 from 1922), its decorative elements are driven by a spring-gear drive using a winding spring. In the design presented by DE patent No. 2933309 of 1981, several movable elements rotate at different angular speeds by using a micromotor and gearbox made in the form of a set of gears. In patent RU No. 94032565 of 1994, the design of a reduction-distribution drive system in jewelry is proposed, containing a miniature rolling bearing, in which the ring-shaped parts rotating at different speeds are the bases for placing decorative elements on them.

Also known is a jewelry product with a drive of movable decorative elements based on a watch mechanism using an anchor mechanism to ensure uniformity and duration of movement, see application DE No. 3232076 from 1984

A common drawback of jewelry with movable decorative elements, for the movement of which a special drive is used, is the rigid predetermination of the movement of decorative elements and, accordingly, a certain mechanistic nature of the overall appearance of the product. Meanwhile, in many cases it is advisable to provide a random, unique play of light, create random, unregulated vibrations that simulate, for example, the versatility of stones included in decorative elements, and thus increase the number of reflections from them.

A number of jewelry is known with movable decorative elements mounted not rigidly on the substrate of the jewelry body, as a result of which, when the latter changes its angular position or changes its movement, decorative elements can change their spatial position in the jewelry body to some extent.

In US patent No. 4294084 of 1981, a finger ring is provided, provided with a tide with a hollow elongated rectangular cutout with a bottom on its top, the inner surface of the cutout being mirrored and a transparent faceted decorative element installed in the cutout groove with the possibility of free movement along the cutout. - a precious or semi-precious stone, forming together with the specified neckline jewelry insert. When moving or changing the position of the finger, this faceted decorative element moves along the notch, changing the direction of the light rays reflected from the mirror faces of the notch passing through the decorative element.

The utility model “Ring with a decorative element” (see patent RU No. 37909 of 2003) is also known, according to which a decorative element, not rigidly integrated into the ring body with the possibility of limited movement, is made in the form of units that are actually attached together , its vertical pillar and base in the form of a spherical segment, which rests on a removable substrate built into the ring body, while the decorative element is its decorating unit through the limiter of its lateral movements, made as a through hole in the housing ring, favored for its contours. The removable substrate is fastened to the ring body by a mechanical connection with fixation, for example, by means of tides-marks. When the movement of the finger or its involuntary shaking changes, the indicated decorative element will sway somewhat, thereby enhancing the visual perception of the unit decorating it.

This utility model "Ring with a decorative element" (patent RU No. 37909 from 2003) is selected as the closest analogue, since it is the closest in technical essence to the claimed invention. A disadvantage of the known technical solution is that it has a relatively narrow scope (a ring with one decorative element forming a single jewelry insert), and, in addition, the moment of resistance to free vibrations (swings) of the decorative element is quite high, due to the friction of its rack about the edge of the restrictive hole of the ring body.

The technical task of the invention is the creation of jewelry with a prefabricated jewelry insert from several decorative elements freely swinging in predetermined directions, forming a definite finished figure.

The technical result of the invention is the placement in the case and coordination in the directions of swinging of decorative elements in order to form a jewelry insert on its outer surface and increasing the suspension sensitivity of each decorative element in the jewelry case.

Obtaining the technical result is ensured by the fact that the jewelry containing the case and the decorative element forming the jewelry insert installed in the case with limited angular movement is provided with several at least two decorative elements placed in the case with the formation on its outer surface of the team jewelry insert, with each decorative element mounted independently swinging in the direction determined by the shape of the jewelry team insertion.

In this case, the range of possible swing angles of the decorative elements is limited by angles of 5-30 °, and the surface of each decorative element in contact with the body is made in the form of one or more sectors of a cylindrical or conical surface, and the decorative element is swung by rolling its specified surface along the surface in contact with it jewelry cases.

The part of the case in contact with the decorative elements can be made movable relative to the general case of the jewelry and the team of several parts interconnected to rotate relative to each other.

Figure 1-5 presents some possible embodiments of the rings, which can be implemented by the claimed invention.

Figure 1-2 presents a ring (in the initial or transport position) with a set of two decorative elements 1,2, forming in the area of the apex of the ring a prefabricated jewelry insert, which is a stylization of a figure like a butterfly. The ring contains a housing 3 with a tide in the region of its apex, in which a flange 4, made in the form of a glass, is fixed in a recessed position. A movable composite substrate is placed on the flange 4, consisting of two parts 5 and 6 rotatable relative to one another, mounted on a U-shaped axis 7, the ends of which are released inside the ring and provided with bulges preventing it from falling out of the housing 3 and flange 4. The thickenings can performed both using the material proper to axis 7, and using small individual flanges attached to the ends of the specified axis by welding or soldering.

On the lower surface of the decorative elements 1 and 2, bases (protrusions) 8, 9 are made, the lower surfaces of which are cylindrical surfaces, the shapes of which are perpendicular to the plane of the ring. The bases are provided with openings parallel to the generatrices of the cylindrical surfaces, in which the fixing decorative elements of the axis 10, 11 are placed with gaps, the ends of which are bent at right angles and attached to the rotary parts 5, 6 of the substrate in any known manner, for example by welding, soldering, gluing. Since the diameter of the axes 10, 11 is chosen smaller than the diameter of the indicated holes in the protrusions 8, 9, in the working position (in which the central part of the substrate is raised relative to the position shown in Fig. 1), the decorative elements 1, 2 can swing on the substrate by some rolling their bases on the surface of its rotary parts 5, 6.

The upper surface of the decorative elements 1, 2 is an imitation of the wings of a butterfly, and it can be made of precious metals and (or) alloys and decorated with engraving and (or) inlay of precious or semiprecious stones.

The operation of the device shown in figures 1, 2, is as follows.

In the initial transport position, the end thickenings of the axis 7 protrude into the ring deeper than the inner contour of the ring in the region of its apex. When putting the ring on the finger, these end thickenings of the axis 7 are supported by the surface of the finger, as a result of which the central part of the composite substrate, which consists of the rotary parts 5, 6, rises up together with the decorative elements 1, 2 mounted on it.

Due to the selected above ratios between the diameters of the holes in the protrusions 8, 9 of the decorative elements 1, 2 and the diameters of the axes 10, 11 on which the decorative elements are mounted, the latter can make limited angular swings on the substrate, which can occur both with the movement of the hand and with involuntary shaking of the fingers. In this case, the light reflection of decorative elements will also change, i.e. the so-called play of light on the entire jewelry as a whole will become more diverse.

Since the cylindrical surfaces of the bases of the decorative elements 1, 2 and their axes 10, 11 fixing them are parallel to each other, the vibrations of the decorative elements will imitate the flapping (flinches) of the butterfly's wings.

Figure 3-5 schematically shows other embodiments of the ring, in which prefabricated jewelry inserts are two types of figures in the form of ornaments. In these variants, the given sway directions of the various decorative elements are different from each other, i.e. not parallel to each other.

In Fig. 3, at the top of the ring on its body 12, two movable rectangular decorative elements are fixed with the possibility of swinging - external 13, made in the form of a frame, and internal 14, made in the form of a square with a central decorating unit 15. The directions of swaying of decorative elements are mutually perpendicular and are shown by arrows. The decorative elements themselves can be made of precious metals and (or) alloys and can have additional decorations in the form of engraving and (or) inlay.

In Fig. 5, on a ring case 16, eight radially located movable decorative elements 18 are fixed on the radially arranged axes 17, framing the central stationary decorating unit 19. The latter, in the general case, can also be not rigidly fixed on the ring case 16. Decorative elements 18 are mounted on the substrate 20. The central protruding part of the substrate 20 is made in the form of a glass in which the central stationary decorating unit 19 is mounted, and the peripheral annular part is a conical surface on which decorative elements 18 are supported by their lower conical surfaces. In decorative elements 18 holes are made (along the axis of their conical surfaces) into which the radially arranged L-shaped fixing axes 17 enter with a gap. The horizontal end of the 17 enters into the openings in the side wall of the central protruding part of the substrate 20, and the curved vertical end is fixed to the peripheral part of the substrate 20 by any known method. After fixing the decorative elements on the substrate, it is installed in the hole in the top of the ring, and then fixed in it through the through hole 21, for example, by welding or soldering. Decorative elements 18 can also be made of precious metals or alloys and decorated with engraving, inlay. Since the decorative elements 18 are freely placed on the axes 17, they can sway relative to the radial directions from the center of the decorating unit 13.

With the movement of the hand or with the involuntary shaking of the fingers, the decorative elements 18 will swing and their light reflection will change accordingly, outwardly looking as random, and, consequently, the variety of light rays from the entire jewelry assembly insert will increase.

Embodiments of the claimed invention are not limited to those presented in figures 1-5. Figures created in variously placed decorative elements can be quite diverse. In this case, the substrate on which the decorative elements are placed can be made both movable (as in FIGS. 1, 2) and motionless, and its surface can be made both flat and concave, and its radius must exceed the radius of the surface supported by her base decorative element.

The base of the decorative elements may be made of materials other than the material of their outer surface, in particular of materials with a larger specific gravity. The base surface itself, supported by the substrate, can be coated with a coating that enhances adhesion to the substrate in order to prevent slipping of the base on the substrate.

The mounting of decorative elements on a substrate can be carried out by other options than those presented in the above figures, it is only important that it provides the ability to swing the decorative elements with a minimum moment of resistance in a fairly small range of angles of their oscillations.

From the analysis of the location of the cylindrical or conical base of the decorative element on the substrate of the jewelry body, it follows that to reduce the moment of resistance to vibrations of the decorative element, i.e. To increase the sensitivity of its pendant, it is advisable to place its fixing axis (or other elements protecting it from falling out of the jewelry body, but not preventing it from certain vibrations, for example, supports on centers, on the core, etc.), possibly closer to the substrate surface. It is also important that this increases the range of swing angles of the decorative element.

If for the jewelry option shown in Fig. 1, denote by D and d the diameter of the aforementioned hole in the base of the decorative element and the diameter of the axis fixing it, respectively, and by R the radius of the surface of the base of the decorative element at the point it touches the substrate of the jewelry body, then the range possible swing angles of the decorative element will be approximately (Dd) / (R × K), where K = H / R, and H is the height of the fixing axis above the surface of the substrate. It can be seen that the smaller K, the greater the range of possible swing angles of the decorative element.

Viewing almost prefabricated jewelry inserts made up of a number of decorative elements showed that in order to obtain an additional visual effect from the mobility of decorative elements, it is enough to ensure their swing within 5-30 °. With large swing angles, there is practically no improvement in visual perception, and the technical difficulties in providing this range of angles increase significantly. Moreover, to ensure the indicated angles of swing of the decorative elements, it is advisable to choose the coefficient K in the range of 0.2-0.8, i.e. take the height H in the range (0.2-0.8) × R.

So, for example, in the practical manufacture of a butterfly-like figure (for the jewelry shown in Figs. 1, 2), the following ratios were used: D = 2 mm; d = 1 mm; R = 10 mm; K = 0.4 (i.e., the height of the fixing axis above the body substrate was 4 mm).

The range of possible swing angles of the decorative element was about 0.25 rad, i.e. approximately 15 degrees.

It should be noted that to ensure the stability of the arrangement and rocking of decorative elements, it is advisable to make the radius of the surface of their base variable, increasing it slightly as you move away from the equilibrium position, which contributes to the stability of the return of decorative elements to their middle position.
