Jewelry connector that is reliably engaged but convenient to open by a single hand

Abstract

A jewelry connector (10), comprising a first half body (11) and a second half body (12). At least one magnet (18) is embedded into each of the first half body (11) and the second half body (12), which thus fit each other by means of magnetic attraction; the surfaces of the first half body (11) and the second half body (12) facing each other have antisymmetric engagement structures of different heights, which have positioning devices (21, 22) that allow the two half bodies (11, 12) to easily overcome a magnetic force to separate sideways in one direction but prevent same from rotating or moving sideways in the opposite direction; the antisymmetric engagement structures constrain five degrees of freedom of the relative movement between the first half body (11) and the second half body (12), and only allow the first half body (11) and the second half body (12) to unidirectionally rotate about a longitudinal axis along which the two half bodies are connected. The jewelry connector of the present invention uses a combination of magnetic attraction and mechanical structures, will not separate by accident when engaged, but can be conveniently opened by a single hand. In the present invention, jewelry is no longer displayed to people just as a single type of jewelry, but can serve with multiple purposes.

Description

Reliable yet easy-to-open jewelry connectors Technical Field

[0001] This invention relates to jewelry links that allow a piece of jewelry to be easily worn onto a ring, bracelet, necklace, earring, or other accessory without the need for tools such as pliers, and facilitates the replacement or reassembly of the jewelry. In particular, the jewelry link according to this invention does not easily fall off after being worn, but can be opened with one hand. Background Technology

[0002] Women may own a large number of pieces of jewelry, but those worn frequently, such as once a week, often account for no more than 20%. However, the mining of heavy metals and gemstones, as well as the cultivation of organic jewelry (pearls), cause irreversible damage to the environment; the overproduction and consumption of jewelry leads to an increase in global carbon emissions. Therefore, promoting the utilization rate of jewelry is one of the technical problems that this invention aims to solve.

[0003] Rings, bracelets, bangles, earrings, and necklaces are all divided into two main parts: the wearing element and the jewelry element. The wearing element, such as the ring band, the earring hook, and the necklace pendant chain, is the part that allows the jewelry to be worn on the body; while the jewelry element, such as diamonds, pearls, agate, and jade, is the essence and highlight of the jewelry. In existing technology, the jewelry element and the wearing element are fixedly paired, with the jewelry element set into the wearing element, usually without the need for removal. The consequence is that a pearl on a ring can only remain on the ring; it cannot be easily removed and installed on an earring, let alone used as a necklace pendant. In other words, a piece of jewelry can only be bound to a specific wearing element and cannot freely display its beauty with other wearing elements. Therefore, achieving multiple uses for a single piece of jewelry is the second technical problem that this invention aims to solve.

[0004] Lobster clasps are the most commonly used jewelry fasteners on the market, but their opening mechanism is cumbersome, difficult to operate with one hand, and prone to malfunctions such as internal spring rusting or failure. Existing technology has seen jewelry fasteners that use magnets for quick opening, which facilitates removing jewelry but also makes it easy to lose the piece. Current jewelry fastener technology has never completely solved the following three major technical problems:

[0005] 1) Cannot be opened quickly with one hand: Jewelry links used on bracelets or necklaces are time-consuming and laborious to wear, and sometimes require the help of others to complete the wearing process. This has led to many necklaces and bracelets being left unused.

[0006] 2) Low reliability: Commonly available magnetic clasps are easily opened accidentally, resulting in the loss of jewelry;

[0007] 3) Complex structure: To prevent the magnetic clasp from being accidentally opened, metal pins or safety chains are used, resulting in a complex structure, wasting materials, and affecting the aesthetics of the jewelry.

[0008] Therefore, improving the reliability and ease of operation of jewelry connectors is the third technical problem that this invention aims to solve. Summary of the Invention

[0009] The first objective of this invention is to provide a jewelry link that eliminates the traditional lobster clasp and abandons the reliance on magnetic attraction alone, instead using a combination of magnetic attraction and mechanical structure to achieve a jewelry link that will not accidentally detach during engagement but can be easily opened with one hand.

[0010] Another objective of this invention is to provide a jewelry link that allows a single piece of jewelry to be worn on different wearing devices. Different pieces of jewelry can be freely combined with the same wearing device, making it simple and quick to arrange and combine multiple pieces of jewelry with multiple wearing devices to form diverse aesthetic expression schemes and create personalized and fashionable outfits.

[0011] Another object of the present invention is to provide a jewelry link that allows for easy replacement of jewelry on any jewelry wearing device, meeting diverse wearing needs and improving the usage rate of jewelry.

[0012] Another objective of this invention is to provide a jewelry link that can reduce the consumption of raw materials such as jewelry and metals, while showcasing aesthetics and helping to reduce carbon emissions and protect the green earth.

[0013] Therefore, according to a first aspect of the present invention, a jewelry link is provided, comprising a first half and a second half, each having at least one embedded magnet and engaging with each other by magnetic attraction, characterized in that the first half and the second half have anti-symmetrical interlocking structures of different heights on their facing surfaces, which can be in a tooth-like interlocking shape, forming a positioning device that allows the two halves to easily overcome magnetic force and separate unidirectionally to one side but prevents displacement to the opposite side.

[0014] Preferably, the anti-symmetrical interlocking structures with different heights are in the shape of inclined planes or curved surfaces; and / or, the positioning device has a structure in which protrusions and grooves cooperate with each other.

[0015] Preferably, the jewelry link is formed by 3D printing or molding; made of metal and / or plastic; the plastic contains resin and additives; and / or, the additives contain plasticizers.

[0016] Preferably, the jewelry link is used to connect necklaces, bracelets, rings, bangles, earrings, and other jewelry and wearing carriers; the jewelry link is generally cube-shaped, spherical, ellipsoidal, heart-shaped, frustum-shaped, prism-shaped, or cylindrical; the embedded magnets in the first half and the second half are cylindrical or cube-shaped; or, the magnets are exposed or hidden inside the material.

[0017] Preferably, the first half and the second half are each linked to an open or closed loop for linking jewelry or a wearable device; the wearable device is a bracelet, bangle, necklace, earring hook, or ring; and / or, the jewelry is a diamond, pearl, agate, or jade.

[0018] According to a second aspect of the invention, one, two, or more chains are successively joined together by connecting the first half and the second half of the invention to form a bracelet or necklace chain of appropriate length.

[0019] Preferably, at least one jewelry link is linked to the jewelry.

[0020] According to a third aspect of the invention, at least one gemstone is combined with an earring carrier by the jewelry link of the invention to form an earring; different gemstones are arranged and combined with different earring carriers to form a variety of earrings.

[0021] According to a fourth aspect of the invention, at least one gemstone is connected to a ring band via a jewelry link of the invention to form a ring; different gemstones are arranged and combined with different ring bands to form a variety of rings.

[0022] According to a fifth aspect of the invention, the jewelry link of the invention can be easily opened with the thumb and forefinger, and the first half and the second half automatically magnetically attract each other when they come close to each other; a gemstone can be combined with different bracelets, bangles, necklaces, earring hooks or rings; or, different gemstones can be combined with the same bracelets, bangles, necklaces, earring hooks or rings to form different bracelets, bangles, necklaces, earrings or rings.

[0023] According to the present invention, traditional technical concepts are broken away from, allowing luxury items such as jewelry to no longer be presented to the world in a static form, but to have their structures and shapes changed at will.

[0024] In existing technologies, no one has ever considered abandoning the traditional thinking of relying solely on the magnetic force of magnets to hold jewelry links together, nor has anyone thought of using a combination of mechanical structures and magnets to achieve a simple and quick opening of secure jewelry links, thereby completely solving a technical problem that has always needed to be solved in the field of jewelry wearing but has never been effectively solved.

[0025] This invention breaks through the conventional thinking of traditional technology, not only solving the technical problem of wearing jewelry with one hand, but also realizing the flexible arrangement and combination between jewelry and the wearing device, making one piece of jewelry multi-functional, and completely changing the way jewelry is worn.

[0032] Figures 6A and 6B are exploded structural diagrams of yet another embodiment of the jewelry link according to the present invention. Detailed Implementation

[0033] Figures 1A and 1B are schematic diagrams illustrating the aesthetic effect of the two halves 11 and 12 of the jewelry link 10 according to the present invention used in earrings. Figures 2A and 2B are sample photographs of the jewelry link 10 according to the present invention used in earrings 16 via the linking rings 13 and 14 of the two halves 11 and 12. Figures 3A and 3B are sample photographs of the jewelry link 10 according to the present invention used in bracelets 17 via the linking rings 13 and 14 of the two halves 11 and 12. Similarly, the present invention can be used in bracelets, necklaces, rings, etc.

[0034] This invention eliminates the traditional lobster clasp and abandons the idea of ​​relying solely on magnetic attraction. Instead, it combines magnetic attraction with mechanical structure, constraining 5 degrees of freedom and restricting 1 degree of freedom, to create a jewelry link that will not accidentally detach during engagement but can be easily opened with one hand.

[0035] The jewelry connector of this invention allows a single jewelry piece 16 to be worn on different wearing supports 15. Different jewelry pieces 15 can be freely combined with the same wearing support 15, enabling diverse arrangements and combinations of multiple jewelry pieces 16 and multiple wearing supports 15 to create varied aesthetic expressions and personalized fashion looks. This invention facilitates the replacement of jewelry pieces 16 on the wearing supports 15, meeting diverse wearing needs and increasing the wearability of the jewelry.

[0036] Figure 4 illustrates a first embodiment of the basic concept of a jewelry link according to the present invention. According to this first embodiment, the main body of the jewelry link is divided into an upper half 1 and a lower half 2; both the upper half 1 and the lower half 2 are interlocked by mechanical structures of varying heights 101, 102; 201, 202, 103, 203. After being attracted by a magnet 18, the height difference of these structures 101, 102; 201, 202 prevents accidental opening under horizontal forces (front, back, left, right), thus constraining the three linear displacement degrees of freedom along the X, Y, and Z axes, and also constraining the two angular degrees of freedom around the X and Y axes; however, only... The upper half 1 has a rotational degree of freedom relative to the lower half 2 along the Z-axis, but the rotational degree of freedom in the opposite direction of the Z-axis is constrained. Furthermore, by rotating along the Z-axis, the constraints on the three linear displacement degrees of freedom of the X, Y, and Z axes and the two angular degrees of freedom of the X and Y axes are released. In this way, the magnetic attraction between the upper half 1 and the lower half 2 can be released with one hand, the jewelry can be changed with one hand, and the magnetic attraction between the upper half 1 and the lower half 2 can be restored with one hand to re-close the jewelry link.

[0037] In the first embodiment, only one pair of magnets 18 is provided between the upper half 1 and the lower half 2; however, in other embodiments, two pairs of magnets 18 or even more pairs of magnets 18 may be provided.

[0038] In the first embodiment, the upper half 1 is prevented from rotating relative to the lower half along the Z-axis by their sidewalls 103 and 203 abutting against each other; however, in other embodiments, the upper half 1 is prevented from rotating relative to the lower half 2 along the Z-axis by a combination of protrusions and grooves, or by inclined surfaces abutting against each other, or by curved surfaces contacting each other.

[0039] As shown in Figures 5A, 5B, and 5C, according to the second embodiment of the present invention, the main body of the jewelry link 10 is divided into an upper half 11 and a lower half 12. Both the upper half 11 and the lower half 12 are interlocked by staggered mechanical structures 21 and 22. After being attracted by the magnet 18, the height difference between the structures 11 and 12 prevents accidental opening when subjected to horizontal forces in the front, back, left, and right directions. This constrains the three linear displacement degrees of freedom along the X, Y, and Z axes, as well as the two angular degrees of freedom along the X and Y axes. However, only the upper half 11 is allowed to... The lower half 12 has a rotational degree of freedom along the Z-axis, but its rotational degree of freedom in the opposite direction of the Z-axis is constrained. Furthermore, by rotating along the Z-axis, the constraints on the three linear displacement degrees of freedom of the X, Y, and Z axes and the two angular degrees of freedom of rotation around the X and Y axes are released. In this way, the magnetic attraction between the upper half 11 and the lower half 12 can be released with one hand, the jewelry can be changed with one hand, and the magnetic attraction between the upper half 11 and the lower half 12 can be restored with one hand to re-close the jewelry link.

[0040] In the second embodiment, two pairs of magnets 18 are provided between the upper half 11 and the lower half 12.

[0041] In the second embodiment, the upper half 11 is prevented from rotating relative to the lower half 12 along the Z-axis by the engagement of their pyramidal grooves 21 and pyramidal protrusions 22. In the second embodiment, the upper half 11 may have a pair of pyramidal grooves 21 symmetrically arranged at both ends; while the lower half 12 may have a pair of pyramidal protrusions 22 symmetrically arranged at both ends.

[0042] As shown in Figures 6A and 6B, the third embodiment of the present invention is similar to the second embodiment, except that: in the third embodiment, the upper half 11 may be asymmetrically provided with a pyramidal groove 21 and a pyramidal protrusion 21; while the lower half 12 may be asymmetrically provided with a pyramidal groove 22 and a pyramidal protrusion 22.

[0043] According to the extensive technical concept of the present invention (i.e., constraining the three linear translational degrees of freedom of the upper half 11 relative to the lower half 12 along the X, Y, and Z axes; constraining the two angular degrees of freedom of the upper half 11 relative to the lower half 12 about the X or Y axis, but restricting the rotational direction of the upper half 11 relative to the lower half 12 about the Z axis), the upper half 11 and lower half 12 of the main body of the jewelry link 10 have a structure that allows them to contact each other 103, 203, engage, mesh, or bite 21, 22, and the upper half 11 and lower half 12 are respectively embedded with magnets 18 for allowing the upper half 11 and lower half 12 to be joined together. The upper half 11 and lower half 12 are prevented from relative torsion (i.e., unable to rotate about the X or Y axis) and relative displacement (i.e., unable to move along the X, Y, or Z axis) in the horizontal plane, preventing accidental opening when subjected to a lateral force along the X or Y axis after the jewelry link 10 is joined.

[0044] The upper part 11 and the lower part 12 face each other and can present shapes such as inclined surfaces, curved surfaces, and staggered heights.

[0045] The materials of the upper part 11 and the lower part 12 can be metal or plastic, and resin and additives can be added. They may be formed by 3D printing or produced in a factory by molds.

[0046] The jewelry connector 10 is used to connect the jewelry carrier 15 and the jewelry 16 in a necklace, bracelet, bangle, earring, or ring. The upper half 11 and the lower half 12 can generally be cubic, spherical, ellipsoidal, or irregular in shape. The cross-section of the embedded magnet 18 can be circular, rectangular, or irregular in shape. The magnet 18 can be exposed, partially exposed, or hidden inside the halves 11 and 12.

[0047] The upper half 11 and the lower half 12, which are opposite to each other, are each connected to an open ring or a closed ring 13 or 14, which are used to connect other accessories 15, 16, 17, etc.

[0048] The two opposite ends of the upper half 11 and the lower half 12 can each be connected to one or two chains 17, which are then linked together to form a closed chain, allowing for various ways of wearing the bracelet or necklace.

[0049] The upper part 11 or the lower part 12 can be linked to an earring, gemstone or jewelry accessory 16 to form a complete earring, which can be used to achieve various ways of wearing the earring by arranging and combining the jewelry carrier 15 and the jewelry 16.

[0050] The upper part 11 or the lower part 12 can be linked to a ring band or a gemstone to form a ring, which can be used to achieve multiple wearing methods by switching between multiple ring gemstones on a single ring band.

[0051] According to the present invention, a piece of jewelry can be conveniently used as a ring, bracelet, necklace, earring, etc., thereby improving the utilization rate of jewelry and solving one of the technical problems to be solved by the present invention.

[0052] According to the present invention, a piece of jewelry is no longer limited to being bound to a specific wearing device, but can freely display its beauty along with other wearing devices, realizing multiple uses for one piece of jewelry and solving the second technical problem that the present invention aims to address.

[0053] The jewelry connector according to the present invention can be opened quickly with one hand without being opened accidentally, thus ensuring the reliability and ease of operation of the jewelry connector and solving the third technical problem to be solved by the present invention. Industrial applicability

[0054] The jewelry link according to the present invention can be widely used in various products such as rings, bracelets, necklaces, etc. It is used in large quantities and is suitable for mass production and global use, which is conducive to protecting the green earth and the human living environment.
