Description

LOCK FOR JEWELRY AND JEWELRY USING A LOCK

The group of inventions relates to the field of jewelry industry and can be used in the manufacture of jewelry, mainly earrings and pendants.

There are known locks for jewelry in which a wire schwenz is attached to the base from one of its ends, and a wire loop is attached to it from the other ends of the loop with the possibility of its radial displacement until it engages with the free end of the wire schwenz (RU 2077243, A44C 7 / 00,

1997).

Such locks are not reliable enough due to their low strength and fragility due to the fact that in order to fix the wire svenza, it must inevitably bend and, as a result, deform.

Locks are more reliable, in which the shvenza is fixed on the base movably and does not require its bending and shape change during fixation.

A lock for jewelry and jewelry using this lock is known, containing a base made in the form of a decorative element, a U-shaped latch rigidly fixed on one of its ends and a smoothly curved shaped metal swivel pivotally mounted on its other end with the possibility of its rotation prior to locking interaction with the U-shaped retainer (WO 00/07480, A44C 7/00, 2000).

Such a lock, however, is not universal, each jewelry size requires its own individual shvenza, and the jewelry has insufficient operational efficiency, since the U-shaped lock is not reliable enough, since its design does not allow for its high strength and over time, especially when intensive use, it loses its fixing ability. Improving the reliability and durability of the lock and jewelry with its use is achieved by making the latch in the form of a hook, mainly spring type (V.I. Marchenkov Yuvelirnoe delo, M., Vysshaya shkola, 1992, p. 180-182). Of the known devices, the closest to the declared castle and jewelry with its use is a lock for jewelry and jewelry with its use, containing a base, a hook-hook fixed to its inside in the form of a rack perpendicular to the base, and a shvenza consisting of a shank and made curved support part, pivotally fixed to the base by means of a pin with the possibility of its rotation to the locking interaction with the free end of the hook (RU 2121283 Cl, 1998). In the lock of jewelry, the shank of the shvenza is straight, its supporting part is smoothly bent, and the hinged fastening of the shvenza is made with the possibility of moving it in a plane perpendicular to the base, while the pin is parallel to the base. In the free part of the locking hook, a groove is made located on the side of the swivel joint (inside the lock).

A jewelry item with such a lock is not technologically advanced to manufacture and requires an increased consumption of material associated with the complexity and laboriousness of manufacturing the shvenza and the consumption of a sufficiently large amount of metal during its manufacture (which is essential when using precious metals). In this case, the shvenza is mainly made of square rolled products with a profile section from 2.2 to 2.5 mm and has a weight of from 0.8 to 2.0 g, depending on its length. Advantageously, about one gram of metal is required for the production of schwenza. Shvenza in such jewelry can be made only manually or by casting, followed by manual finishing operations to put the shvenza in place in the castle, which increases the cost of the jewelry as a whole. In addition, the lock in such a piece of jewelry is not universal enough, since a shvenza of one standard size, as a rule, does not fit jewelry of other standard sizes. Therefore, the design of such jewelry is not universal.

The task of the group of inventions is to create a universal lock for various jewelry of various sizes, convenient, reliable and durable in use.

The technical result provided by the inventions is to reduce the cost of jewelry by simplifying the design of the castle, reducing its metal consumption and increasing manufacturability.

The task in terms of the lock device is solved, and the technical result is achieved due to the fact that in the lock for jewelry containing a base, a fixed hook on it in the form perpendicular to the base racks, and a schwenzie, consisting of a shank and a curved supporting part, pivotally fixed to the base by means of a pin with the possibility of its rotation to the locking interaction with the free end of the hook, the shank of the schwenzi is L-shaped, its supporting part is made of a Z-shaped, and the articulated fastening of the schwenz is made possible when it is rotated to move in a plane parallel to the base, while the pin is perpendicular to the base. In the free part of the hook-clamp on its side opposite to the pin, a groove can be made under the shank of the shvenzy. In the shank at its bend, a recess under the hook-clamp can be made from the inside. The groove in the locking hook and the recess in the shank in the locked state of the shvenzy are preferably located at the same distance from the base. The end part of the shank can be flattened.

The problem in terms of the device jewelry is solved, and the technical result is achieved due to the fact that in the jewelry product containing the base, rigidly fixed on its inner side, the hook-clamp, made in the form perpendicular to the base of the rack, pivotally mounted on the inner side of the base by means of a pin with the possibility of rotation to a locking interaction with the retainer, a fastener, consisting of a shank and a curved supporting part, and at least one decorative element t, the shvenza shank is L-shaped, its supporting part is Z-shaped, and the hinge is pivotally mounted so that it can move in a plane parallel to the base, while the pin is installed on the inner side of the base perpendicular to it. The shank of the schwenza in its fixed state can be located parallel to the base or at an angle to the base with an angle of inclination of up to 45 degrees. In the free part of the hook-clamp on its outer side, a groove can be made under the shank of the shvenza. In the shank at its bend, a recess under the hook-clamp can be made from the inside. The groove in the locking hook and the recess in the shank in the locked state of the shvenzy are preferably located at the same distance from the base. The end part of the shank can be flattened. The decorative element can be made in the form of a lining mounted on the outside of the base. The decorative element can be made in the form of a hinge, freely suspended in the eye made in the base. The group of inventions is illustrated by drawings.

In FIG. l schematically shows a lock for jewelry; figure 2 is an embodiment of jewelry in the form of earrings; on Fig.Z is a top view of a fastener equipped with a recess for a hook-latch. The lock for jewelry (Fig. L) contains a base 1, which is made of metal, including any precious metal, and can have any shape, including a figured one, and a fixed hook fixed to it, mainly by soldering 2 mainly from precious metal in the form of a rack perpendicular to the base 1. The lock bolt 3, which is made mainly of precious metal, is pivotally fixed to the base 1 by means of a pin 4 with the possibility of its rotation in a plane parallel to the base 1. The bolt 3 is made, for example, of square rolled metal with a profile cross section from 0.8 to 1.2 mm or from round wire with a diameter from 1.0 to 1.2 mm. The pin 4 is located perpendicular to the base 1 and is fixed on it mainly by soldering. Its free end is riveted. Schwenza 3 consists of a shank 5 of a L-shaped form and a supporting part 6 of a Z-shaped. The shank 5 is spaced from the surface of the base 1 at a distance of mainly 5-8 mm, depending on the size of the lock and, if the lock is used in an earring, on the thickness of the earlobe. In an advantageous embodiment, the lock in the free part of the hook-latch 2 on its side opposite to the pin 4 (i.e., to the swivel joint of the shvenza 3) has a groove 7 for the shank 5 of the shvenzy 3, and in the shank 5 at its bend a recess 8 for the hook-and-hold hook 2 is made on the inside. In this case, the groove 7 and the recess 8 are located mainly at the same distance from the base 1. The groove 7 and / or the recess 8 may be absent in the lock, which does not fundamentally affect its operability. The end part of the shank 5 is made, for example, flattened and provided with impressions of the manufacturer’s mark and assay mark. The base 1 may be provided with a ring for mounting mounted decorative elements (not shown in the drawing). On the base 1 itself, decorative elements can also be located, for example, of precious or semiprecious stones (not shown in the drawing). The functioning of the lock, for example, in the predominant case of using it in an earring, consists in inserting the hook-retainer 2 into the hole in the earlobe and turning the shvenzy 3 until it engages with the hook-retainer 2. Moreover, the presence of the groove 7 and the recess 8 further increases the reliability of the lock connections. Schwenza 3 is much more technological in manufacturing than in the well-known castle, which allows, in particular, to produce it by means of a die cut. 40-60% less metal is spent on the production of schwenz 3 than on the production of a known lock's schwenzi, while the savings are from 0.4 to 1.0 g of metal on each schwenz, which significantly reduces the metal consumption and, as a consequence, the cost of the lock. The simplicity of the design of the castle simplifies its assembly, which also reduces the cost of the lock. The simplicity of the design of the castle enhances its versatility, as the swanza 3 can be easily adapted to various sizes of jewelry. The design of the lock provides ease of use and its high reliability in operation and durability.

The lock made in accordance with the invention is simple to manufacture, has a low cost and has increased versatility for various jewelry. It is convenient and reliable in operation. Jewelry (Figure 2) contains a base 1, which is made of metal, including any precious metal, and can have any, including curly, shape, and fixed on it, mainly by soldering, the hook-clamp 2 mainly from precious metal in the form perpendicular to the base of 1 rack. The lock screw 3, which is made mainly of precious metal, is pivotally fixed to the base 1 by means of a pin 4 with the possibility of its rotation in a plane parallel to the base 1. The lock screw 3 is made, for example, of square steel with a profile cross-section from 0.8 to 1.2 mm or from round wire with a diameter from 1.0 to 1.2 mm. The pin 4 is located perpendicular to the base 1 and is fixed on it mainly by soldering. Its free end is riveted. Schwenza 3 consists of a shank 5 of a L-shaped form and a supporting part 6 of a Z-shaped. The shank 5 is spaced from the surface of the base 1 at a distance of mainly 5-8 mm, depending on the size of the jewelry and, in the case of an earring, on the thickness of the earlobe. In an advantageous embodiment, the jewelry in the free part of the hook-latch 2 on its side opposite to the pin 4 (i.e., to the swivel joint of the shvenza 3) has a groove 7 for the shank 5 of the shvenza 3. In the shank 5 at its bend from the inside, a recess 8 can be made under the hook-latch 2 (Fig.Z). In this case, the groove 7 and the recess 8 are located mainly at the same distance from the base 1. The groove 7 and / or the recess 8 may be absent, which essentially does not affect the operability of the castle mechanism in jewelry. Base 1 may be provided with an eyelet

(ring) 9 for attaching at least one decorative element in the form of a hinge 10. On the base 1 can also be placed decorative elements 11, for example, of precious or semiprecious stones, in the form of individual elements (as shown in Figure 2) or fixed on the outside of the base 1 lining (not shown in the drawings). In addition, the base 1 itself can be made, for example, in the form of a figured decorative element of precious metal. The end part of the shank 5 is made, for example, flattened and provided with impressions 12 of the manufacturer’s mark and assay mark. The functioning of the jewelry, for example, in the form of an earring, consists in inserting the hook-retainer 2 into the hole in the earlobe and turning the shvenzy 3 until it engages with the retainer 2. In this case, the presence of a groove 7 and a recess 8 further increases the reliability of the lock connection of the jewelry.

Schwenza 3 is much more technologically advanced in manufacturing than in the well-known jewelry, which allows, in particular, to produce it by means of a die cut. 40-60% less metal is spent on the production of schwenz 3 than on the production of the knawenz of a known product, while saving from 0.4 to 1.0 g of metal on each schwenz, which significantly reduces the metal consumption and, as a result, the cost of jewelry . The simplicity of the castle design simplifies the assembly of jewelry, which also reduces the cost of jewelry, for example, earrings. The simplicity of the design of the lock enhances the versatility of the jewelry, since 3 can be easily adapted to various sizes of jewelry. The design of the jewelry provides ease of use and its high operational reliability and durability. Jewelry is easy to manufacture, has a lower cost compared to similar well-known jewelry, has increased versatility. It is convenient and reliable in operation.

Thus, the use of the proposed group of inventions allows you to create a universal lock for various jewelry of various sizes, convenient, reliable and durable in use, reducing the cost of jewelry by simplifying the design of the castle, reducing its metal consumption and improving manufacturability.
