Description

TECHNICAL FIELD

The present utility model relates to the field of jewelry industry, namely jewelry locks, and can be used in personal items, jewelry or jewelry, such as earrings, pendants or brooches.

BACKGROUND OF THE ART

Earrings or pendants for pierced body parts are highly popular among users. Typically, the latch opening and closing mechanism of such jewelry essentially includes a pin passing through the pierced body part and some type of retainer or latch that retains the pin. Sometimes the operation of fastening/unfastening a regular earring is very difficult due to the rigid fixation of the pin, which makes it necessary to manually remove the pin from the latch. This is inconvenient and problematic for the user, it can ruin nails and manicure, cause pain or injury due to its protrusion. In addition, in some types of pin locks, the pin must be unbent to remove the jewelry, which will subsequently lead to early failure and the need to repair the lock. To eliminate such inconvenience to the user, known locks use a spring, which provides an improved mechanism for moving the latch or fastener from a fastened position to an unfastened position. Locks for wrist-worn jewelry are also known that use a spring to releasably connect two ends of the jewelry.

From KR101925869 (B1) (published 02/26/2019) a clasp for decoration is known, which has a design that can improve the appearance by reducing the thickness of the clasp body. The decoration clasp includes: a hanging assembly connected to one end of the decoration and having a locking groove on the top surface; a locking body having an inlet opening into which a hanging assembly is received on one side, the locking body being connected to the other end of the decoration through a cavity connected to an upper opening from the inlet opening; a latch having a latch at the bottom of one end and a stop at the bottom of the other end, the latch having a hinge suspended in the center and connected to the locking body by a hinge through an upper hole; and a cone-shaped compression spring mounted in the cavity to elastically support the bottom of one side of the latch plate around the hinge with the top. When inserting the hanging unit into the entrance hole, the latch secures both ends of the decoration and hangs on the locking groove. When the top surface of one side of the latch plate is pressed, the cone-shaped compression spring is compressed and the latch is released from the locking groove. The spring can be made of steel wire.

From the utility model patent RU216580 (published on February 14, 2023), a lock-fastener is known, which is a pancake that includes a body with holes for a rod and latch fixation, inside of which there is a latch equipped with a hole for the rod, a hole for fixing the latch, a button, and a groove. and a stop, a spring installed in the groove of the latch, and a pin installed in the holes for fixing the latch, made on the body and the latch. In the closed position, in which the lock-clasp is fixed on the jewelry bar, the spring rests against the body, thereby causing the latch to move, disrupting the alignment of the holes for the bar. In the open position, the case is in an open position, in which the clasp can be easily removed from the jewelry bar. To open the fastener, you need to press the button, as a result of which the latch will move and the holes for the rod will become coaxial.

From US patent application US2013298603 (A1) (published November 14, 2013) a support assembly for earrings is known, including an earring post having a locking groove, a housing, a handle and a spring. The spring is installed on the handle. The handle is installed inside the housing in such a way that the spring is pressed at one end to the handle and at the other end to the housing. Together, the handle and body provide an opening to accommodate the earring post, with the handle retaining a locking protrusion within the hole. The spring moves the locking protrusion toward the center of the hole. When the handle is pressed under spring pressure, it rotates, moving the locking tab away from the center of the hole, allowing the shackle post to be inserted into the hole. When the pressure on the handle is released, the displacement of the spring forces the locking tab back to the center of the hole, which engages the locking groove of the shackle post.

The disadvantage of the known solutions is that the spring is not protected in any way in the lock design and is subject to strong influence of the external environment, which can lead to the need for repairs and deteriorate the aesthetic appearance of the product. In addition, the spring itself does not have sufficient durability with a large number of compression cycles due to its low elastic properties. In known solutions, the spring is installed between the moving elements without any fixation and can easily move, creating problems in unfastening the lock. In addition, well-known jewelry locks have a complex configuration of lock elements, are labor-intensive to manufacture and assemble, and have low repairability. In particular, during repairs or modifications, for example, when soldering additional elements, inlaying stones and other operations known to a person skilled in the art for modifying the decoration, the decoration is heated, as a result of which the spring is also heated, which leads to a loss of its properties and a decrease in its durability and failure. This leads to the need to disassemble the jewelry. Disassembling such high-precision jewelry with its characteristic high detail is a labor-intensive and expensive process and can ruin the appearance of the product, i.e. can render the entire piece of jewelry unusable, which will lead to the need for its disposal and melting down. In some cases, for complex jewelry, repair may be completely impossible, and to replace the spring, it will be necessary to dismantle individual elements, after which they must be replaced with new ones. Thus, the known solutions have low manufacturability and, as a consequence, low versatility, since their use may be advisable for products of simple design or jewelry, the service life of which and value are usually not significant, which makes it possible to neglect the durability and manufacturability of their jewelry locks.

The solution to the US patent application US2013298603 can be chosen as the closest analogue of the claimed utility model. In addition to the above-mentioned disadvantages, this known solution uses a rotary spring, which has low manufacturability, since it also limits the possible design options for the lock elements, since their shape is tied to the shape of the ends of the rotary spring, which rest on the sides of the body and handle.

The technical problem to be solved by the claimed utility model is to increase the manufacturability and versatility of a jewelry lock, in particular to ensure improved maintainability, durability, ease of manufacture and assembly, and ample opportunities for decorating and modifying the jewelry after production.

IMPLEMENTATION OF THE UTILITY MODEL

Next, the design of the jewelry lock according to the preferred embodiment of the present utility model and its operating principle will be described in detail.

A general view of the jewelry lock 100 in its assembled configuration is shown in FIG. 1.

As shown in FIG. 2, the jewelry lock 100 includes a body 1, a rocker arm 2 and a spring 3. In this case, the spring 3 is a compression spring. The body 1 contains a hole 4 for receiving the mate of the decoration, for example, an earring, pendant or brooch, and the rocker 2 contains a hole 5 for fixing the specified mate of the decoration when placed in the cavity 11 for receiving the rocker 2. The body and the rocker are pivotally connected to each other, For this purpose, holes 6 and 9 are made in the body 1 and rocker arm 2, respectively. The assembled lock body 1 is an all-metal, one-piece cast structure.

As shown in FIG. 2-3, the rocker arm 2 has a surface 10 that is flush with the edge 12 of the body 1 and abuts against the part 13 of the body cavity from the inside when the rocker arm 2 is located inside the cavity 11 of the body 1 in an uncocked state, thereby making it possible to limit the movement of the rocker arm inside the cavity when transferring from a cocked state to an uncocked state. The surface 10 of the rocker arm 2 on one side and the edge 12 of the housing on the other side limit the travel of the spring when pressing and releasing the pressure button 8. Thus, the user will not be able to push the pressure part too hard and break the lock, and the spring will not fall out of its seat , which increases the manufacturability of the lock, namely its reliability and performance characteristics.

The location of the rocker arm inside the cavity of the body assembly with their hinged connection makes it possible to eliminate play between the rocker arm and the body, and also eliminates the interaction of the jewelry lock with items of clothing and protects the rocker arm from contamination.

Housing 1 additionally contains a cradle 7 inside the cavity 11, made in the form of a protrusion with a recess. The lodgment 7 is configured to receive one end of the spring, in particular at least two non-working coils of the spring.

As shown in FIG. 4, the rocker 2 contains a pressure part 8 in its lower part, made in the form of a cylindrical passage with a hole on one side. In this case, as best seen in Fig. 3, the pressure part 8 protrudes from the housing 1. According to the present utility model, the pressure part 8 is configured to receive the other end of the spring 3. Thus, the spring 3 is located inside the housing 1 between the housing cradle 7 and the pressure part 8 of the rocker arm 2. Thanks to this arrangement of the spring 3 provides the possibility of precise positioning of the spring in the housing and the rocker arm, pivotally connected to each other. Thus, the possibility of unwanted slipping of the spring and its exit from the seat is eliminated. In addition, the design of the body 1 and the rocker 2 proposed in this utility model, containing a cradle 7 and a pressure part 8, between which a spring 3 is located, allows you to shift the location of the spring below the main part of the jewelry lock, containing a hinge connection and holes for receiving and fixing the mating part decorations. Thus, in contrast to the known solutions of the prior art, in which during each interaction the surface of the spring is exposed to the external environment, the arrangement of the spring according to the present utility model is more technologically advanced, since the spring is isolated from the holes for receiving and fixing the mating part of the decoration, as shown in Fig. 2, 5, 6, and is less susceptible to external influences, such as dirt, sea water, salt, etc., which in turn ensures an increased service life of the jewelry and reduces the need for its repair. Thus, the lock according to the present utility model has increased manufacturability, in particular, durability comparable to the service life of the jewelry itself containing such a jewelry lock. In other words, the lock structure will not fail prematurely.

In addition, the isolated arrangement of the spring in accordance with the present utility model also allows soldering of jewelry containing a jewelry lock in accordance with the present utility model, when placing the spring location area in water or other cooling liquid, in order to prevent overheating of the spring, as a result of which the spring may lose its properties. Thus, the jewelry lock according to the present utility model allows for repairs and modifications, for example, soldering of additional elements, inlaying with stones, etc., without the need to disassemble or melt down the jewelry itself containing such a jewelry lock.

As stated above, spring 3 is a compression spring. Thanks to the use of a compression spring, the possible design options for the elements of the jewelry lock are not limited, in particular, the rocker 2 can have any simple or complex shape with high relief and high detail, which increases the individuality of the user.

In fig. 2, 4 show a straight compression spring according to a preferred embodiment of the present utility model. However, in another embodiment, the spring may be bent. The curved spring provides additional advantages in the form of providing radial movement of the rocker arm, which is consistent with the hinged mounting of the rocker arm in the body cavity and improves the operation of the lock, and also provides additional rigid fixation of the spring 3 between the cradle 7 and the pressure part 8.

In a preferred embodiment of the present utility model, the lock spring can be made of titanium or its alloys. Springs made of titanium and its alloys are not subject to fatigue or corrosion, which means they have an increased service life; a lock with such a spring will not fail prematurely. Titanium springs do not lose their properties when heated, unlike springs made of steel and gold alloys, which also further increases the manufacturability of a jewelry lock. In some embodiments of the proposed design, manufacturing a spring from steel, gold and other alloys used in the jewelry industry is also possible.

In one of the embodiments of the present utility model, the pressure part 8 contains grooves (not shown in the drawings). The grooves prevent the lock from slipping out of the user's hands after unfastening. This improves the ease of use of the lock and its reliability. The pressure portion protruding from the body pinpoints where the force is applied so that the user does not waste time searching for the point of application of force while trying to unfasten the lock. In a preferred embodiment, the pressure portion may be decorative, adorned with precious or semi-precious stones.

The body 1 and the rocker 2 are manufactured using 3D printing and vacuum injection molding using resistive materials. The use of 3D printing and vacuum injection molding in the manufacture of lock parts allows us to produce a lock of any shape, with a sufficiently high relief and high detail. In addition, the method of 3D printing and vacuum injection molding using resistance material ensures the production of high-precision parts without additional machining and expands the range of metals that can be used to make a lock and which cannot be machined. It should also be noted that the production of lock parts with high relief and detail, with openwork patterns using stamping, used in the state of the art, is almost impossible. In particular, the method of 3D printing and vacuum injection molding is preferable for the manufacture of the holder for the spring, rocker arm and case, since the precise execution of these elements further increases the manufacturability of the jewelry lock and its durability.

The lock elements can be made of both precious metals (for example, gold, silver, platinum, palladium) and non-ferrous alloys (brass, bronze, cupronickel, nickel silver, etc.). By way of example, the alloys include 750, 585 gold alloys containing nickel and zinc, silver and copper, 950 platinum alloys, 925, 875 silver alloys and other cast alloys.

The jewelry lock is assembled as follows. A spring 3 is installed in the cylindrical passage of the pressure part 8 of the rocker arm 2, then the rocker arm with a preinstalled spring is placed in the cavity 11 of the housing 1, so that the other free end of the spring 3 enters the cradle 7. Then the upper part of the housing is installed and the jewelry lock is soldered with a laser. Thus, a solid lock body is obtained, which does not contain weak points and cannot fall apart or break, and in which the spring is reliably protected from external influences. In particular, the spring is located in a sealed solid body, which is impossible to achieve in any of the known locks.

The lock works as follows. In the closed position, which is shown in FIG. 5, holes 4 and 5 are not coaxial. To insert the counter part of the decoration, the user presses the pressure part 8, as a result, the axes of the holes 4 and 5 are aligned (aligned) and the counter part of the decoration can be easily inserted into them. After this, the user releases the pressure part 8, while the spring 3 tends to straighten and return the rocker to its original position, shown in Fig. 5, so that the body returns to the closed position, ensuring the fixation of the mate of the jewelry in holes 4, 5. Thus, due to the increased manufacturability and versatility of the jewelry lock according to the present utility model, simple and reliable fixation of the mate of the jewelry in the jewelry lock is ensured.
