Abstract

FIELD: jewelry industry.

SUBSTANCE: invention relates to locks for interchangeable jewelry objects (products) such as necklaces/bracelets/anklets/rings/earrings and any other objects related to jewelry. The lock for the jewelry system contains two branches and a sleeve that can be moved, with sliding, to a position in which it covers at least parts of both branches. This movement of the sleeve corresponds to the transition of the lock from the open to the closed state. At the same time, each branch has an end, and in the open state the ends of the branches are more distant from each other than in the closed state. One of the branches in the section adjacent to its end is configured with the possibility of permanent attachment by welding to the chain of the jewelry system. At the same time, at least parts of both branches are configured to fit in the closed state of the lock to the inner surface of the sleeve, and the sleeve is capable of sliding along the chain, at least when the lock is open. Moreover, the sleeve has such an axial size that when the lock is closed, it covers and hides the ends of both branches. The task solved by the invention is to develop an attachment system for jewelry components and locks for it, which can be easily used to change or add pendants, ornaments, bracelet pendants, chains and/or other jewelry components in order to be able to create many new design options using the same parts and/or easily add jewelry components. Another task is to create a jewelry lock that can prevent the loss of any component of the lock, since none of its components detach from the chain, even when it opens when replacing the suspension or ornaments.

EFFECT: expansion of the range of solutions for the jewelry industry.

Description

Technical field

Embodiments of the invention relate to locks for interchangeable jewelry objects (products) such as necklaces/bracelets/anklets/rings/earrings and any other objects associated with jewelry. In particular, such jewelry locks (Interchangeable Jewelry Connectors - IJC) make it possible to make jewelry components, such as ornaments/key chains/pendants/chains, etc., easily interchangeable (i.e., attachable/detachable) and, thereby, allow you to easily to design interchangeable jewelry components, resulting in numerous design possibilities in the jewelry field using the same type of products.

State of the art

Jewelry usually goes on sale with a permanent design that cannot be modified and matched to a special event, mood, costume, etc. This results in the possession of a wide range of jewelry, which can be expensive and impractical. Jewelry is usually provided with known locks of various types, such as: lobster-lock ("Lobster claw") [Fig. 1A], spring lock ("springring") [Fig. 1B], various screw locks illustrated in FIG. 1C, and various types of hooks that can be designed to be chained through, as illustrated in FIG. 1D-1F.

Some jewelry pieces are modular and can be used with different jewelry components and ornaments. For example, US 2008/0250616 describes a jewelry lock provided with a means capable of holding easily replaceable jewelry components. US 2012/01.74626 describes a multi-piece jewelry system that can be worn in a variety of ways. However, said jewelry contains various screw and/or spring locks which can be complex and time consuming to install.

Disclosure of invention

The problem solved by at least certain embodiments of the invention is to provide an attachment system for jewelry components and locks for it, which can be easily used to change or add pendants, ornaments, key chains, chains and/or other jewelry components in order to be able to create many new designs using the same parts and/or easy addition of jewelry components.

Another object, solved by at least some embodiments of the invention, is to provide a jewelry lock capable of preventing the loss of any component of the lock, since none of its components are detached from the chain, even when it is opened when replacing the pendant or ornaments.

Other objects to be solved by the invention will become apparent from the following description.

The invention, in at least some of its variants, relates to a lock that makes it possible to make jewelry components interchangeable. The lock comprises a cotter pin having two branches and configured in such a way that the branches are adapted to press one against the other in order to reduce the distance between them and thereby allow them to be jointly covered, while when the pressure is released, the distance between the branches increases. The lock also contains a sleeve that can be put on the chain with the ability to move along it. The inner diameter of the sleeve is chosen such that it can receive the branches of the specified cotter pin and hold them in a compressed state, allowing you to close the lock and securely hold at least one jewelry component.

According to an embodiment of the invention, one branch of the cotter pin is attached to one end of the chain. The chain may be part of a piece of jewelry, such as a bracelet/anklet/ring/earring, etc., to which the corresponding branch may, for example, be permanently welded or otherwise attached.

According to an embodiment of the invention, one branch of the cotter pin remains unattached, so that one (one) or more ornaments / key chains / pendants / various jewelry objects, such as a necklace / bracelet / earring can be placed (placed) on the unattached branch.

In another aspect, the invention relates to a modifiable attachment system for jewelry components comprising one or more locks, wherein the single or each lock comprises a cotter pin having two branches that can be pressed against each other to reduce the distance between them and thereby provide , the possibility of their joint coverage. In this case, as soon as the pressing pressure is removed, the distance between the branches increases. The lock also includes a sleeve through which a chain can be threaded so that the sleeve is able to move along it. The inner diameter of each sleeve is made sufficient to cover the branches of the specified cotter pin to keep them pressed against each other. This makes it possible to close said lock and securely hold at least one jewelry component on it. This system also includes a chain attached to one branch of each cotter pin.

According to an embodiment of the invention, the jewelry system further comprises one or more jewelry components or other jewelry objects adapted to be held by one or each of the locks.

In another aspect, the invention relates to a lock in the form of a ring, which makes it possible to make jewelry components interchangeable. The lock contains: a) a cotter pin in the form of a part having the shape of an open ring, so that one end of the part faces its other end, and b) a sleeve mounted, with the possibility of sliding movement, on one end of the specified part, so that as a result of the displacement of the sleeve towards the other end of this part, the ring-shaped lock becomes closed, while as a result of the movement of the sleeve in the opposite direction, this lock opens.

Other aspects of the invention can be summarized as follows:

1. A lock serving as an attachment mechanism to ensure the interchangeability of jewelry objects and containing:

a) a cotter pin having two branches and configured in such a way that its branches can be pressed against each other in order to reduce the distance between them and thereby ensure the possibility of co-covering these branches with an increase in the distance between the branches in the event of the termination of said pressing, and

b) a sleeve adapted for threading a chain into it, providing the sleeve with the ability to move along the chain, and the internal diameter of the specified sleeve is selected sufficient to cover the specified branches to keep them in a state of pressing against one another, thereby ensuring the closing of the specified lock and securely holding at least one jewelry component; wherein:

the state of mutual pressing of the branches is maintained due to the forces of tension and/or friction arising between the inner surface of the sleeve and the branches, which tend to increase the gap between them and return to their original free state; a

the lock is able to move to the open state by a single opening operation, in which an external force is applied to the sleeve, sufficient to exceed the threshold value of the specified friction forces and move the sleeve along the chain.

2. The lock according to aspect 1, in which one branch of the cotter pin is attached to one end of the chain.

3. The lock according to aspect 1, wherein the chain is part of a piece of jewelry, such as a bracelet, anklet, a ring or an earring, to which a cotter pin branch can be welded or otherwise attached.

4. The lock according to aspect 2, in which one branch of the cotter pin is left unattached so that one or more ornaments or other jewelry objects can be installed on it.

5. Connecting system to ensure the interchangeability of jewelry objects, containing:

a) one or more locks serving as an attachment mechanism, each lock comprising: i) a cotter pin having two branches configured to be pressed against one another to reduce the distance between them and thereby allow them to be co-engaged with an increase in the distance between the branches in the event of termination of the specified pressing; ii) a sleeve adapted for threading a chain into it, allowing the sleeve to move along the chain, wherein the inside diameter of said sleeve is chosen to be sufficient to encircle said branches to keep them pressed against one another, thereby closing said lock and securely holding at least one jewelry component; moreover, the state of mutual pressing of the branches is maintained due to the forces of tension and/or friction arising between the inner surface of the sleeve and the branches, which tend to increase the gap between them and return to their original free state; and the lock is able to move to the open state by a single opening operation in which an external force is applied to the sleeve sufficient to exceed the threshold value of the specified friction forces and move the sleeve along the chain, and

b) a chain attached to one branch of each cotter pin.

Implementation of the invention

Next will be considered several variants of the invention, illustrated in the accompanying drawings. Like or the same designations throughout the various drawings, as far as possible, correspond to like or identical parts and components. The illustrated embodiments of the invention are for illustrative purposes only, and one of skill in the art will readily appreciate from the following description that alternative constructions and methods may be implemented, without departing from the scope of the invention.

In FIG. 2 schematically illustrates a lock 10 according to the invention. The lock 10 can be described as having two main components, the first being the sleeve 11 and the second being the cotter pin 12. As best seen in FIG. 3A and 3B, the cotter pin 12 has two branches 13 and 14, and the cotter pin can be configured so that its branches 13, 14 can be pressed against each other to reduce the distance between them (as shown in Fig. 3B). This will allow both branches to be inserted into the corresponding ring or sleeve 11 (for example, as shown in Fig. 2). After the pressure is removed, the distance between the branches 13, 14 will increase (as shown in Fig. 3A) due to the elastic properties of the cotter pin 12.

According to an embodiment of the invention, one branch of the split pin 12 (for example, branch 14) can be permanently connected (for example, by welding or other means) to the chain, while the other branch (for example, branch 13) remains free (i.e. has a free (unattached) end 7, as shown in Fig. 5A). As a result, a pendant (or alternative jewelry component) can be passed (passed) through and/or put on (put on) it, for example, as schematically illustrated in FIG. 5A, in which the leg 14 of the cotter pin 12 is shown attached to one end of the chain 17 so that the pendant 18 is passed around and/or slipped on the leg 13.

Fig. 8A and 8B illustrate an embodiment of a lock 10 comprising a cotter pin 12 that can be configured to be attached (possibly permanently) with one strand (strand 14) to a chain 17. In this example, such attachment can be facilitated by the presence of an attachment component 19, which in this embodiment initially attached to the end of leg 14. Alternatively, component 19 may be attached to the end of chain 17 (this option is not shown) and, accordingly, can be configured to attach to leg 14 or 13.

In FIG. 8A the chain 17 is shown initially not attached to the lock 10, while in FIG. 8The end of the string 17 is shown inserted into the component 19, which can then be acted upon, for example by crimping, to attach the strand 14 to the string 17. As shown in FIG. 8A, 8B, before being attached to the lock 10, the chain 17 can, for example, be passed through the sleeve 11, so that after the chain has been attached, the sleeve can be pushed over both branches of the lock. According to an aspect of the invention, embodiments of a two-leg split pin and sliding sleeve lock combination may have increased utility while maintaining a relatively unremarkable aesthetic appearance, which may be desirable in a jewelry system.

Such increased utility can be achieved by making one branch of the cotter pin (for example, branch 14 in Fig. 5) in such a way as to ensure its attachment to the chain and at the same time use the same branch to facilitate holding the sleeve in place after it has been placed on the pressed against one another. another branch. Holding the sleeve in a predetermined position is facilitated by the fact that the legs (including the branch attached to the chain) are configured to fold outward against the inner surface of the sleeve.

In another example, the arcuate head 15 of the cotter pin located between and connected to two branches is configured to, firstly, increase the resilience required for spreading the branches, and, secondly, serve as a convenient half-loop type structure for attaching to other jewelry components such as chains, locks, pendants, etc.

In yet another example, a bushing that is designed to hide (when mounted on top of it) a two-strand cotter pin mechanism (see, for example, FIG. 9 and its description below) gives an aesthetic appearance to lock options, essentially resembling a jewelry component or part of it (rather than just a functional part such as a lock, which usually remains visible - see Figs. 1A-1F).

In this case, the sleeve, which preferably does not have any holes, cuts, slots, etc. on its periphery through which its internal volume could be seen, helps to hide the mechanism of two branches located inside it.

In FIG. 9A and 9B show a variant of the lock 10 in the open (see FIG. 9A) and closed (see FIG. 9B) states, respectively. Considering the closed state first (illustrated in FIG. 9B), it can be seen that in this example at least one leg (leg 13) is made shorter than the other leg 14. In this example, the longer leg 14 is shown attached to chain 17. However, it should be noted that the chain 17 may alternatively be attached to a shorter leg 13.

In some cases, attaching a chain to a long branch of a cotter pin reduces the chance that the chain and another branch, while inside the sleeve, will come into contact and interfere with each other. If it were necessary to attach the chain to a shorter branch, this could require an increase in the diameter of the sleeve, which would adversely affect the aesthetic performance of the lock.

The difference in the lengths of the branches becomes more noticeable and measurable in the lock, in which both branches are more or less pressed against each other at a sufficiently significant distance from the arcuate head 15 of the lock. This is the case, for example, in the closed state of the lock, when both branches are held relatively close to each other by the sleeve 11. In FIG. 9B, branch 13 is shown extending from head 15 to its end 133, and branch 14 is shown extending from head 15 to its end 144 projecting beyond end 133 so that branch 14 extends beyond end 133 of branch 13.

According to one aspect of the invention, the dimensions of the sleeve 11 can be chosen such that its axial dimension L (for example, when it is to be pressed by one of the axial ends against the head 15) is sufficient to cover and hide the branches in the closed state, at least in some embodiments. castle. In the embodiment of FIG. 9B, the axial dimension L of the sleeve 11 is chosen for the case where the two branches have different axial extents. However, such concealment of the branches is also preferred in embodiments with branches having essentially the same axial extent.

This concealment of the branches in the closed state of the lock gives it an aesthetic quality so that it resembles a piece or component of a piece of jewelry (rather than a purely functional lock, which usually remains visible (see FIGS. 1A-1F)). In the example of FIG. 9A, an aspect of the invention will be discussed in relation to a possible method for bringing at least certain embodiments of the lock into a closed state. In a possible first operation of this method, the long branch of the lock (branch 14) is positioned (preferably manually) in a position in which the part of this branch, adjacent to its end 144, is located in the sleeve 11.

When the sleeve 11 is in this position, it can be used (when held by the user's hand with a lock) as a support base, relative to which you can press another branch (branch 13) to press it towards the branch 14. When both branches are located one close different (for example oriented one along the other), the cotter pin 12 of the lock can be easily inserted into the sleeve 11 and/or the sleeve 11 can be easily pushed over the branches to bring the lock into the state illustrated in FIG. 9B.

As will be readily appreciated by one of skill in the art, cotter pin 12 may be of any shape or size, as long as it has two legs.

As most clearly shown in FIG. 4, the sleeve 11, which can be shaped close to the shape of a bead, can be adapted to be threaded onto a jewelry chain 17 (see, for example, Fig. 5) in such a way that it can slide along the chain 17 as freely as possible. In this case, the sleeve 11 has an internal diameter sufficient to accept the branches 13, 14 of the cotter pin 12 in such a way as to keep them in a compressed state due to tension and forces acting between the branches 13, 14 and the inner surface 16 of the sleeve 11.

To engage the lock 10, one can push the branches 13, 14 of the cotter pin 12 towards each other, and then simply push the sleeve 11 over them. The branches 13, 14 will create a force acting on the sleeve 11, as they tend to increase the distance between them in order to return to its original (free) state, illustrated in FIG. 3. After the sleeve 11 has been pushed over the branches 13, 14 of the cotter pin 12 to bring them into a compressed state, the sleeve 11 is maintained substantially fixed on the cotter pin 12 as a result of tension and/or friction forces that are generated between the inner surface 16 of the sleeve 11 and branches 13, 14, which remain pressed against the surface 16.

During normal use of the jewelry system containing the lock, the sleeve 11 is not subjected to any significant forces tending to disengage it from the branches. As a result, the sleeve is held in this position, corresponding to the closed state of the lock, due to the radially outward forces acting on the lock branches.

In order to open the lock 10, sufficient external force can be applied to the sleeve 11 that exceeds a threshold value, for example, the frictional force acting on the sleeve as a result of its interaction with the branches, in order to slide the sleeve 11 along the chain 17 and, thereby, easily detach sleeve 11 from cotter pin 12, i.e. implement a release mechanism that is triggered by such an action.

After the sleeve 11 has been pushed over the branches 13, 14 of the cotter pin, it can be used as a locking device that fastens and holds, for example, a hanger 18 inserted into and/or onto the cotter pin 12, as schematically illustrated in FIG. 5V.

As will be readily understood by one of skill in the art, bushing 11 can be made into any size, shape, or design, provided it has the desired inside diameter to compress the cotter pins one against the other.

It should be noted that the lock 10 serves as a fast and simple attachment mechanism, allowing interchangeability of jewelry objects while maintaining the minimum size of the lock, i.e. while maintaining the aesthetic characteristics and original design of jewelry without making any changes to the design intent.

It should also be noted that the attachment system for interchangeable jewelry objects according to at least certain embodiments of the invention can be used not only as a conventional jewelry lock, but can easily be used to create new jewelry or combinations thereof. This connection system thus opens up endless design possibilities.

For example, a particular pendant on a chain can be easily replaced with another pendant and reused on a bracelet/anklet/ring/earring, etc. In another example, a necklace can easily be paired with another necklace to form a long chain, with or without ornaments. In yet another example, the necklace may be paired with a bracelet to create a longer piece of jewelry, or wrapped around the bracelet. In the following example, a piece of an earring can be attached to a chain to create a chain with the piece of the earring serving as an ornament.

Next, FIGS. 10A-10F illustrating examples of possible applications of lock 10 variants to form a variety of attachment systems for interchangeable jewelry components to conveniently create new jewelry.

In FIG. 10A shows an example of how four possible pendants 180 and a chain 17 containing at each end a variation of the lock 10 of the invention can be used to form a variety of jewelry combinations. In this example, the four pendants 180 are a pair of earrings 181, a necklace pendant 182, and a heart-shaped bracelet pendant 183.

Pendants 180 and chain 17 with locks 10 may, for example, belong to the same person, and examples will be given below to show how the interchangeability facilitated by the use of the proposed lock 10 can be used to form a variety of jewelry combinations.

The chain 17 in this example can be conveniently worn as a necklace or choker and when worn around the neck (not shown) can have a clasp 10 at the top of the necklace (i.e. on the back of the neck as shown in the top left of FIG. . 10A) or at the bottom of the necklace (as shown in the upper right of fig. 10A). As shown in FIG. 10A, chain 17 may be threaded through pendants 180 (as shown on the left side of FIG. 10A); alternatively, any pendant can be attached to the lock (ie fixed between two locks) to form a so-called "split-like" necklace. In addition, the chain can be threaded through several selected pendants (as shown in the lower part of Fig. 10A).

In FIG. 10B also illustrates the possibilities of using multiple pendants and a chain with two locks at both ends to form various new designs of jewelry. Here, the chain can be structured like a tie-shaped necklace (see top left of Fig. 10B) by snapping one (upper) clasp onto the chain and then using the bottom clasp (located at the end of the chain segment hanging from the top clasp) to attach one or more pendants to the necklace.

In the embodiment shown at the top right of FIG. 10B, the chain can have an unsymmetrical configuration with any pendant attached to the lock (ie fixed between two locks). At the bottom of Fig. 10B is an example of a shorter chain (possibly part of a bracelet) attached to the bottom of the necklace as an aesthetic continuation of the necklace. In this example, the chain can also be given a tie-like configuration by passing the chain through a hole in a pendant that is connected to a lock attached to the other end of the chain.

In FIG. 10C and 10D are other examples of how two pieces of a split bracelet can be attached to a necklace chain with pendants in between the pieces attached to two opposite clasps. Fig. 10E and 10F illustrate how earrings (see FIG. 10E) can be used in conjunction with chains of split bracelets and pendants to form various jewelry combinations, and/or how various jewelry combinations can be formed from a chain with additional ring chains and chain bracelet (see Fig. 10F). Thus, the examples presented illustrate the possibilities of using the embodiments of the lock according to the invention to provide modularity in the production of new jewelry or systems from jewelry objects already in the customer's possession.

As shown in FIG. 7A-7D, according to one aspect of the invention, an embodiment of the lock 100 may be configured to include, as a cotter pin, an open ring shaped piece 120. Part 120 in this embodiment also has two branches 130, 140, each of which has an end 131, 141, respectively. The lock also has a sleeve 110, which is slipped onto one of the branches of the part 120, namely the branch 130. By bringing the sleeve 110 to the other branch 140 (i.e., to its end 141), it is possible to fix the lock 100, as this is shown in FIG. 7B. By sliding the sleeve 110 in the opposite direction, the lock 100 can be unlocked as shown in FIG. 7A.

Plane 'A', marked in FIG. 7B, corresponds to the plane in which the part 120 with branches 130, 140 can be located when the sleeve 110 encloses both ends 131, 141 of the branches. The direction 'B' marked in FIG. 7A and 7B is the viewing direction of the lock sleeve 100 substantially in plane 'A'.

When viewed along the direction 'B', the view is directed towards the sleeve 110 and the parts of the branches adjacent to their respective ends 131, 141. In FIG. 7C is also a view (in the direction of the arrow 'B') when the lock 100 is (as in FIG. 7A) in the unlocked state. In FIG. 7D shows a similar view when the lock 100 is (as in FIG. 7B) in the closed state.

As shown in FIG. 7C, the legs 130, 140 of the open lock 100 are not aligned with each other with respect to their ends 131, 141, possibly because the cotter-pin piece 120 is configured along a helical path H, possibly spring-loaded to the cotter pin 120. properties that lead to a mismatch of the ends of the branches.

It can be seen that the cotter pin (item 120) is configured to overcome the inconsistency in the positions of its ends 131, 141, i.e. sleeve 110 in the position shown in FIG. 7D, being advanced past the end of one of the legs, meets the opposite end (end 141) of the other leg, which prevents it from falling off the previous leg (and hence from part 120).

In at least certain embodiments, the degree of misalignment of the ends 131, 141 (noted in FIGS. 7A and 7C) can be specified through the distance 'd' between the segments of the spiral section H for adjacent ends 131, 141 and through the values of the width (possibly diameter) D2 branches and/or width (possibly diameter) D1 of the sleeve that satisfies the relationship that 'd' is less than D1 and/or D2.

To bring the lock 100 into the closed state illustrated in FIGS. 7B and 7D, the ends of the branches (preferably by hand) are placed (at least for a short moment) one against the other. As a result, the sleeve 110 can be moved to cover both ends 131, 141 of the branches. In this position, when the legs are depressurized, their configuration will allow them to return to an inconsistent state (best shown in FIG. 7C) to the extent that the inner surface of sleeve 110 allows (as illustrated in FIG. 7D).

As a result, the response of each branch relative to the inner surface of the sleeve creates a force F aimed at holding the sleeve in this position. Retracting sleeve 110 to the position shown in FIG. 7C will allow the branches to move completely into the position shown in FIG. 7C, in which the lock is in the unlocked state.

The foregoing description and graphical examples have been presented for purposes of illustration only and do not limit the invention in any way, i. many other various modifications of the invention can be implemented without going beyond its limits.
