A device for connecting pieces of jewelry contains a hollow body 1 in the form of a cylindrical sleeve, a cylindrical rod 2 with a terminal element in the form of a flat shank 3 and a locking device made in the form of a spring 4. The housing 1 has a longitudinal axis of symmetry along which a through hole 5 is made. In the cover 6 of the housing 1, on the inner side, a connecting socket is made in the form of a groove 7. In the cover 6 of the housing, a through hole 8 is made at an angle to the groove 7. In a specific example, the groove 7 and the through hole 8 are perpendicular yarny. On the inner side of both covers 6 and 9 of the housing 1 are installed locking protrusions 10, which are designed to block the shank 3 in the connecting groove 7 from popping up.

The shape of the through hole 8 in the cover 6 of the housing 1 and the connecting groove 7 corresponds to the shape of a flat shank 3. The dimensions of the through hole 8 and the groove 7 slightly exceed the dimensions of the flat shank 3, while the excess value is selected from the condition to allow free passage of the shank 3 through the hole 8 and groove 7 with the formation of a gap. Thus, the shank 3 of the rod 2 is configured to pass through the through hole 8 in the cover 6 of the housing 1 and placed in the groove 7 when it is rotated through an angle by which the through hole 8 is turned towards the groove 7, in particular by an angle of 90 °, the spring 4 is made with the possibility of reversibly securing the shank 3 in the connecting groove 7.

The cylindrical rod 2 may have shanks 3 at both ends. On the cylindrical rod 2 from the side opposite to the shank 3, a decorative element or lock can be fixed for attachment to the product. The housing 1 may be a decorative element, or a decorative element may be fixed to it. The case and the rod may include tabs or channels for accommodating one or more precious stones, natural materials or manufactured materials, such as turquoise, carnelian, kahalong, malachite, onyx, chrysoprase, white jade, lapis, inlaid with pearls, amethyst, rhodolite, garnet, aquamarine, tourmaline, diamond, ruby, sapphire, emerald, pearl, spinel or wood or metal of various designs and colors in accordance with aesthetic preferences.

The case and the core in jewelry are usually made of precious metals, mainly gold and silver. Other materials, such as brass, nickel, platinum, palladium and steel, can also be used because they are not very chemically active, retain their shape and strength and require only minimal maintenance to preserve shine.

The cylindrical rod 2 is designed to form a chain link. If the groove 7 and the through hole 8 are made in one cover 6 of the housing 1, the housing is a single element of the chain, mainly the terminal element. In the second cover 9 of the housing 1, a groove 11 and a through hole 12 can be made, similar to the groove 7 and the through hole 8. In this case, a second rod 2 can be used, the shank 3 of which is configured to pass through the through hole 12 in the cover 9 of the housing 1 and placement in the groove 11, and the spring 4 is made with the possibility of reversibly securing the shank 3 of the second rod 2 in the connecting groove 11. This specific embodiment is a symmetrical chain link that includes two rods 2 with the same size m. Other embodiments may be asymmetric chain links having different sizes of rod 2.

The device is used as follows.

Before use, the spring 4, installed inside the housing 1, is released.

At the end of the rod 2, opposite the shank 3, by any known means, a decorative element is fixed. A rod 2 with a shank 3 is passed through a through hole 8 in the cover 6 of the housing 1 into the through hole 5 in the housing 1. Since the shape of the shank 3 corresponds to the shape of the through hole 8 in the cover 6 of the housing 1, and the dimensions of the through hole 8 slightly exceed the dimensions of the shank 3, the rod freely passes into the housing 1, compressing the spring 4. The rod 2 is rotated through an angle equal to 90 ° in a specific example, inserting the shank 3 into the groove 7 from the inside of the cover 6. Since the shape of the shank 3 corresponds to the shape of the groove 7, and the dimensions of the groove 7 several pre The dimensions of the shank 3 are increased, the shank 3 freely enters the groove 7. The spring 4 is opened, pressing the shank 3 against the inner surface of the cover 6 into the groove 7. The chain links containing the housing 1 and the shaft 2 with the shank 3 are in a fixed closed position (Fig. 1, Fig. 2).

If it is necessary to replace the decorative element or just if necessary, disconnect the chain links, press the rod 2, the spring 4 is compressed, releasing the shank 3, which comes out of the groove 7 (Fig. 4, Fig. 5). The rod 2 is rotated through an angle equal to 90 ° in a specific example, and is taken out of the housing 6 through the through hole 8 in the cover 6. The spring 4 is expanded by pressing against the inside of the cover 6. The chain links comprising the housing 1 and the shaft 2 with a shank 3, are in the open position (Fig. 1, Fig. 2).

Thus, due to the spring 4 located inside the housing 1, the rod 2 is reversibly fixed with the shank 3 in the housing 1.

If the rod 2 has shanks 3 at both ends, it can be used as a connecting link for two cases 1, which can be various decorative elements. So various decorative elements can be connected in a necklace, necklace, beads, bracelet, earrings, ring, etc. Moreover, decorative elements can be easily replaced with others.

If a through hole 12 is made on the inside of the second cover 9 of the housing 1, and a groove 11 is made at an angle to it, the housing 1 can be used as a connecting link for two rods 2, which, as they themselves can be different decorative elements, can also have shanks 3 at both ends.

The claimed device allows you to easily and reversibly create various combinations of interchangeable decorative elements. To replace the decorative element, it is necessary to press on the end of the shaft 2 and pull out the shank 3.

The device allows you to independently create various types of jewelry from various interchangeable modules, the number of which can be changed, and by adjusting the length, you can get a bracelet, necklace or earrings of any size.

A sample device is manufactured using known equipment in the factory. According to the applicant, these circumstances indicate that this utility model meets the criterion of “industrial applicability”.
