Definitions

  • the present disclosure relates to a jewelry link composite, a jewelry link of such a jewelry link composite and a method for producing such a jewelry link composite.
  • a jewelry link assembly i.e. an arrangement of a large number of individual (jewelry) links that can be positively coupled to form a composite, which combines to form a (necklace) chain, a bracelet or tennis bracelet, an ankle chain or a finger or toe ring is well known.
  • Such a jewelry link composite can be converted into a circumferential, closed ring shape and in such a ring shape state can be reversibly expanded/stretched up to a predetermined maximum width when put on or taken off as well as when worn.
  • Such a jewelry link assembly can be slipped over the head, hand, foot, finger or toe in the closed ring shape state, or can rest against the relevant part of the body with a precisely adjusted width.
  • An elastic element which is formed, for example, by an elastic band made of at least partially elastomeric plastic or by an elongated spring element, is preferably completely received by the circumferential jewelry links, which are positively connected to one another to form a closed ring shape. Due to its elastic properties, the elastic element can also be reversibly expanded and supports the expandability of the jewelry link composite converted into the closed ring shape. The elastic element is usually not visible from the outside and therefore does not affect the appearance of the decorative link combination.
  • Such a decorative link assembly is, for example EP 3 562 347 B1 , which discloses the preamble of claim 1, known.
  • a bracelet is disclosed herein, which is composed of a large number of decorative links that are strung on an elastic element, which is designed here as a spring.
  • the decorative links are lined up on the spring via their through holes running in the direction of arrangement and then connected to one another.
  • a decorative link has a hollow connecting pin that continues the through hole, from the free end of which two locking projections protrude in opposite directions.
  • the decorative element has side openings on two opposite side walls that run in the direction of arrangement.
  • the two locking projections of one jewelry link can be inserted into the axial through hole of another jewelry link and engage in its side openings.
  • the side openings are dimensioned such that the locking projections can be brought into engagement with them with a certain amount of play in the arrangement direction.
  • fastening bolts are inserted into the jewelry link via holes provided on the underside of the jewelry link and welded to the jewelry link. The jewelry links are thus connected to one another to form a captive, ring-shaped jewelry link assembly.
  • US 10 271 619 B1 a composite of decorative links connected to one another in a form-fitting manner, which have a through hole running in the direction of arrangement in order to be able to accommodate an elastic support element, for example a spring.
  • the decorative link On the front, the decorative link has two locking hooks that are aligned in the direction of arrangement and, in the normal state, run parallel to one another and each project outwards. The locking hooks are each arranged next to the through hole.
  • the decorative link has a rectangular opening on the back (which is opposite the front) through which the locking hooks of another decorative link can be inserted.
  • the locking hooks are compressed so that they can be inserted into the rectangular opening at the back of another jewelry link. Once the locking hooks have passed the opening at the back, they expand back to their normal state due to their material flexibility and their projections engage the side openings.
  • the rectangular side openings are dimensioned so that the rectangular hooks can be brought into engagement with them with a certain amount of play in the direction of arrangement.
  • the jewelry links have openings on their side walls in order to be able to accommodate locking elements of another jewelry link.
  • the wall thickness must therefore have a certain minimum thickness, so that such decorative links are limited in their filigree or delicate structure.
  • the production of small jewelry links and thus also delicate jewelry link assemblies is therefore more difficult.
  • dirt can penetrate through the side openings on the decorative links into the axial through holes of the decorative links, in which the elastic element is accommodated. Dirt that has penetrated can impair the freedom of movement and thus the elasticity of the elastic element, so that the spreading of the ring-shaped decorative link composite is made more difficult or impaired.
  • a decorative link composite is to be made available which can have delicate decorative links with a small wall thickness.
  • the entry of dirt into the jewelry links should be prevented in order to ensure simple and low-friction movement of the elastic element within the jewelry links.
  • the present disclosure provides a jewelry link assembly with a plurality of individual jewelry members that can be coupled to one another in a form-fitting manner, each of the plurality of jewelry members having a through hole extending in the direction of arrangement of the jewelry members for receiving a preferably elastic support element extending through several, preferably all, jewelry members having.
  • the plurality of decorative links each have at least two locking tongues arranged next to the through hole and projecting in the arrangement direction with elongated holes extending in the arrangement direction.
  • the inner flanks of the through hole have at least two inwardly projecting locking lugs.
  • the locking tongues of one decorative link can be inserted into the through hole of another decorative link and engaged with the locking lugs of the other decorative link in a form-fitting manner, but with a certain amount of play in the direction of arrangement.
  • the present disclosure relates to a jewelry link assembly, in particular in the form of a bracelet, a necklace or a ring, which has a large number of jewelry links arranged in a row that are positively connected to one another.
  • Each decorative link has a hollow body which has a pair of transverse surfaces extending transversely to the direction of arrangement of the decorative link.
  • One transverse surface defines a front surface of the Decorative link and the other transverse surface defines a back surface of the decorative link.
  • the front surface and the back surface are opposite each other.
  • the hollow body has a pair of longitudinal surfaces extending in the arrangement direction, one longitudinal surface being a left surface and the other longitudinal surface being a right surface, and the left surface and the right surface opposing each other.
  • each decorative member has two locking tongues which extend outwardly from the front surface of the hollow body along the arrangement direction and are each provided on diametrically opposite sides of the first opening.
  • the two locking tongues are each provided with an elongated hole that extends in the direction of arrangement.
  • the decorative link has a radially inwardly projecting locking lug on an inside/inner flank of the hollow body on two diametrically opposite sides of the through hole.
  • the two locking tongues and the two locking lugs are designed and arranged in such a way that the elongated holes of one jewelry link can engage with the locking lugs of another jewelry link.
  • Such a jewelry link assembly has the advantage that the mobility of the jewelry members relative to one another in the arrangement direction can be achieved without side openings having to be provided in the side walls of the individual jewelry members.
  • the ratio of the length of the elongated holes to the diameter of the locking lugs determines the maximum distance between two jewelry links.
  • the side walls of the decorative links are designed without side openings and are therefore continuous, so that they are stable and even delicate decorative links with small wall thicknesses can be created.
  • additional dirt entry can be avoided since the side walls of the decorative links, which run in the direction of arrangement, are not interrupted or broken through by side openings.
  • this type of coupling does not affect the external appearance of the individual jewelry links, which increases the freedom of design.
  • the arrangement direction corresponds to the direction in which the locking tongues of one jewelry link are inserted into the through hole of another jewelry link, or the axial direction of a straight composite or the circumferential direction of a circular (closed) composite.
  • the individual jewelry links can be identical, but also different, as long as the individual jewelry members are compatible with one another with regard to the coupling elements (locking tongues and locking lugs) and can be coupled according to the invention.
  • the jewelry links are connected to one another in a form-fitting manner, they form a captive connection, regardless of any support element (e.g. spring/thread/chain) that may be accommodated inside, which remains connected to one another even if the support element is damaged or tears. This means that no individual jewelry links, which can be very valuable, can be lost, which increases the wearer's feeling of security.
  • any support element e.g. spring/thread/chain
  • Each jewelry link (including a last jewelry link) preferably has a rigid, i.e. plastically non-deformable, jewelry link body.
  • the locking lugs extend in the arrangement direction from the jewelry link body, in which the through hole is provided for receiving the support element.
  • the locking lugs of one jewelry link are inserted into the through hole of another (previous) jewelry link in a state that is plastically bent towards one another (insertion state).
  • the locking lugs are plastically bent away from each other compared to the insertion state in order to positively connect one jewelry link to the other (preceding) jewelry link (connection state).
  • the locking lugs are bent apart between the insertion state and the connection state by external force (not due to the inherent material flexibility or restoring force).
  • An advantageous embodiment of the disclosure provides that the jewelry link composite is guided through the through holes of the jewelry links, preferably elastic, supporting element, preferably in the form of a spring.
  • the support element of this type tensions adjacent jewelry links flat against each other, with the length or diameter of the jewelry link composite being able to be increased by stretching the elastic support element.
  • the diameter or circumference of the jewelry link composite of this type can, among other things, be individually adapted to the desired body part on which the jewelry link composite is to be worn using the support element.
  • the locking tongues of one jewelry link are plastically bendable inwards before insertion into the through hole of the other jewelry link and plastically bendable outwards after insertion into the through hole of the other jewelry link.
  • the jewelry links can be cast from precious metal, such as gold.
  • the decorative links are cast with the locking tongues in their locking position and the locking tongues are only bent plastically inwards or towards each other before they are connected to another decorative link.
  • plastically bending the locking tongues of one jewelry link relative to one another they can be easily and quickly inserted into the through hole of the other jewelry link. Due to the subsequent plastic expansion of the locking tongues back to the initial state, the elongated holes of one jewelry link are easily and reliably brought into engagement with the locking lugs of the other jewelry link and remain in this locking position for a long time due to a memory effect resulting from the manufacturing process or casting.
  • a first closure member can be coupled to the first jewelry member and a second closure member can be coupled to the last jewelry member from the plurality of jewelry members coupled to one another, and that the closure members can be coupled to one another in order to achieve the coupled to one another To be able to connect jewelry links to form a closed ring or closed circlet.
  • closure links enables a simple and safe transfer of several jewelry links coupled together into a closed ring/hoop shape.
  • the closure members can easily be connected to one another from outside since they do not have any plastically bendable coupling elements or locking lugs. More precisely, both the first closure member and the second closure member each have a through hole or transverse hole, which are aligned (with each other) when the closure members are coupled to one another.
  • a closure element preferably a, in particular rod-shaped, bolt or locking pin is inserted into these (with each other) aligned through holes or transverse holes when the ring is coupled to the closed state (of the jewelry link assembly).

  • connection of the first end of the support element to the first closure member and the second end of the support element to the last decorative link via the first and second locking pins is particularly secure.
  • the locking pins prevent the ends of the support element from coming loose. The locking pins thus prevent undesirable slipping of the support element within the jewelry link composite that has been converted into the ring/hoop shape.

  • a bending mandrel 32 is used, the diameter of which must be of a similar size, in any case not significantly smaller, than the diameter of the through hole 12.
  • Fig. 8 is an exploded perspective view of a first closure member 34, a second closure member 36 and a final decorative member 38 that receive the support element 10.
  • the first and second closure members 34, 36 are constructed essentially like a jewelry member 2.
  • the closure links 34, 36 have the same material as the decorative links 2, 38.
  • the closure members 34, 36 have a first and a second locking hollow pin 40, 42, which extends outwards from the front surface 22 of the first and second closure members 34, 36 in the arrangement direction A.
  • the locking hollow pins 40, 42 are preferably (material) integrally connected to the closure members 34, 36.
  • the through hole 12 of the first or second locking member 34, 36 continues in the first or second locking hollow pin 40, 42.
  • the first locking hollow pin 40 of the first closure member 34 is designed to be inserted into the through hole 12 of the second closure member 36.
  • the second locking hollow pin 42 of the second closure member 36 is designed to be inserted into the through hole 12 of the last decorative member 38.
  • the diameter of the locking hollow pins 40, 42 is dimensioned so that it is only slightly smaller than the diameter of the through channel 12. The locking hollow pins 40, 42 can therefore be inserted into the through hole.
  • the first locking hollow pin 34 has a first transverse bore 44.
  • the second locking hollow pin 36 has a second transverse bore 46.
  • the first and second closure members 34, 36 differ from each other in that the second closure member 36 has a transverse bore 48 which is arranged transversely to the through hole 12 and breaks through the longitudinal surfaces 24, 25 of the second closure member 36.
  • the second closure member 36 in contrast to the first closure member 34, has no locking lugs 18. If the first and second closure members 34, 36 are connected to one another, the first connecting hollow pin 40 of the first closure member 34 is inserted into the through hole 12 of the second closure member 36. In this state, the first transverse bore 44 is aligned with the transverse bore 48 in the second closure member 36. In this state, the first closure member 34 and the second closure member 36 can be coupled by means of a first locking pin 50 inserted into the aligned transverse bores 44, 48.
  • the last decorative link 38 differs from a normal decorative link 2 in that it has a transverse bore 52 which is arranged transversely to the through hole 12 and breaks through the longitudinal surfaces 24, 25 of the last decorative link 38.
  • the last decorative link 38 in contrast to the other decorative links 2, does not have any locking lugs 18. If the second closure member 36 and the last jewelry member 38 are connected to one another, the second connecting hollow pin 42 of the second closure member 36 is inserted into the through hole 12 of the last jewelry member 38. In this state, the second transverse bore 46 is aligned with the transverse bore 52 in the last decorative link 38. In this state, the second closure link 36 and the last decorative link 38 can be coupled by means of a second locking pin 54 inserted into the aligned transverse bores 46, 52.
  • the first and second locking pins 50, 54 are optimally made of the same material as the first and second locking members 34, 36.
  • the arrows E indicate the direction in which the locking pins 50, 54 are used to couple the locking members 34, 38 of the last Decorative link 38 and the ends of the support element 10 are inserted.
  • Fig. 8 shown that the closure members 34, 36 and the last decorative member 38 accommodate the support element 10.
  • the locking tongues 14 of the first decorative link 2 are bent inwards or towards each other, starting from their initial state. Then the locking tongues 14 of the first jewelry link 2 are inserted into the through hole 12 of the first closure member 34, so that the elongated holes 16 of the locking tongues 14 of the first jewelry link 2 are aligned with the locking lugs 18 of the first closure member 18. Then the bending mandrel 32 is inserted into the through hole 12 of the first decorative link 2 in the direction of the first closure link 34. The locking tongues 14 of the first jewelry link 2 are then plastically bent outwards or apart into their initial state with the aid of the bending mandrel 32, so that the locking tongues 14 engage with the respective locking lugs 18. Then this process is repeated with the second jewelry link 2 and another jewelry link 2 until the arrangement has the desired number of jewelry links 2.
  • the support element 10 is then inserted from the side of the first closure member 34 into its through hole 12 and into the through holes 12 of all jewelry members 2 up to and including the jewelry member 2. Then the second closure member 36 is coupled to the last jewelry link 38 using the second locking pin 52. At the same time, the last jewelry link 38 is coupled to the second end of the support element 10 in the manner described above using the second locking pin 52.
  • the second locking pin 52 can be connected to the last decorative link 38 in a materially bonded manner, in particular by laser welding.
  • the support element 10 is temporarily fixed with the first locking hollow pin 40 of the first closure member 34 under elastic prestress.
  • the free front surface of the first locking hollow pin 40 can be connected to the first end of the support element 10 in a materially bonded manner, in particular by applying the material from which the closure member or the decorative members are made, to form the connection point 56.
  • the first locking member 34 is then coupled to the second locking member 36 and to the first end of the support member 10 using the first locking pin 50 in the manner described above.
  • the support element 10 is coupled to the first closure member 34 in such a way that the adjacent closure members 34, 36 and decorative members 2, 38 are elastically biased against one another in the arrangement direction. If the support element 10 is a spring, the first locking pin 50 can sit between two spring coils (the same applies to the second locking pin 54).
  • the first locking pin 50 can be connected to the second closure member 36 in a materially bonded manner, in particular by laser welding.
  • jewelry elements 6 can be fixed via the receiving sections 4 of the jewelry members 2, the last jewelry member 38 and the first and second closure members 34, 36.
  • Fig. 9A is a side view of a jewelry link assembly 1 with a number x of jewelry links 2.
  • the jewelry link assembly 1 is here in the relaxed state shown. In the relaxed state, the front surface 22 of each jewelry link 2 is in flat contact with the rear surface 23 of an adjacent jewelry link 2.
  • Fig. 9B is a side view of the jewelry link composite 1, starting from Fig. 9A was spread out or expanded. As a result of the spreading, the diameter of the jewelry link assembly 1 increases. In the expanded state, the front surface 22 of a jewelry link 2 and the rear surface 23 of an adjacent jewelry link 2 no longer touch each other, but are spaced apart from one another.
  • Fig. 9C is a side view of a jewelry link assembly 1 with a number y of jewelry links 2.
  • the number y of jewelry links 2 is the in Fig. 9C shown jewelry link assembly 1 is greater than the number x of jewelry links 2 of the in Fig. 9A shown jewelry link assembly 1.
