Definitions

  • the present disclosure relates to an ornamental link assembly, an ornamental link of such an ornamental link assembly, and a method for producing such an ornamental link assembly.
  • a jewelry link i.e. an arrangement of a large number of individual (jewellery) links that can be positively coupled together to form a composite, which can be linked to form a (necklace) chain, a bracelet or tennis bracelet, an ankle chain or a finger or toe ring, is well known.
  • Such a set of decorative links can be converted into an encircling, closed ring shape and can be reversibly spread/extended to a predetermined maximum width in such a ring shape when it is put on or taken off and when it is worn.
  • the closed ring shape such a set of decorative links can be slipped over the head, the hand, the foot, the finger or the toe, or it can rest on the body part in question with an exactly adjusted width.
  • An elastic element which is formed, for example, by an elastic band made of at least partially elastomeric plastic or by an elongate spring element, is preferably completely accommodated by the encircling and form-fittingly connected decorative links to form a closed ring shape. Due to its elastic properties, the elastic element can also be spread apart reversibly and supports the ability to spread the decorative link composite that has been converted into the closed ring shape. The elastic element is usually not visible from the outside and therefore does not impair the appearance of the decorative links.
  • Such a decorative link composite is, for example EP 3 562 347 B1 known.
  • a bracelet is disclosed here, which is composed of a large number of decorative links which are lined up on an elastic element which is designed here as a spring.
  • the ornamental links are lined up on the spring through their through holes running in the arrangement direction, and then connected to each other.
  • a decorative link has a hollow connecting pin continuing the through hole, from the free end of which two latching projections protrude in opposite directions.
  • the decorative link has side openings on two opposite side walls running in the arrangement direction. To connect the individual decorative links, the two latching projections of one decorative link can be inserted into the axial through-hole of another decorative link and engage in its side openings.
  • the side openings are dimensioned in such a way that the locking projections can be brought into engagement with them with a certain amount of play in the direction of arrangement.
  • fastening bolts are inserted into the jewel link through holes provided on the underside of the jewel link and are welded to the jewel link. In this way, the decorative links are joined together to form a captive, ring-shaped decorative link composite.
  • U.S. 10,271,619 B1 a composite of form-fittingly interconnected decorative links which have a through-hole running in the arrangement direction in order to be able to accommodate an elastic support element, for example a spring.
  • the decorative link On the front side, the decorative link has two locking hooks which are aligned in the arrangement direction and which 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 jewel has a rectangular opening at the back (which is opposite to the front) through which the locking hooks of another jewel can be inserted.
  • the jewelry link to the both transverse sides arranged transversely to the front and rear sides and extending in the direction of arrangement have rectangular side openings.
  • the locking hooks are squeezed together so that they can be inserted into the rectangular opening at the back of another jewel. Once the locking hooks have cleared the opening at the back, they expand back to their normal state due to their material flexibility and their protrusions engage the side openings.
  • the rectangular side openings are sized so that the rectangular hooks can be engaged with them with some play in the direction of assembly.
  • a large number of decorative links are first connected to one another. Then the spring is inserted into the axial through hole of each jewelry link. The spring is soldered to the first decorative link and the last decorative link. In order to transform the chain into a ring shape, the first and the last decorative element are soldered together.
  • the decorative links have openings on their side walls in order to be able to accommodate latching elements of another decorative link.
  • the wall thickness must have a certain minimum thickness, so that such decorative links are limited in their filigree or delicateness.
  • the production of small decorative links and thus also filigree decorative link composites is thus made more difficult.
  • a decorative link assembly is to be made available which can have filigree decorative links with a small wall thickness.
  • the entry of dirt into the decorative links should also be prevented in order to ensure simple and low-friction movement of the elastic element within the decorative links.
  • the present disclosure provides an assembly of decorative links with a multiplicity of individual decorative links that can be coupled with one another in a form-fitting manner, each of the multiplicity of decorative links having a through hole extending in the arrangement direction of the decorative links for receiving a preferably elastic support element extending through several, preferably all, decorative links having.
  • the plurality of decorative elements each have at least two locking tongues arranged next to the through-hole and protruding 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 a decorative link can be inserted into the through-hole of another decorative link and positively engaged with the locking lugs of the other decorative link, but with a certain amount of play in the arrangement direction.
  • each ornamental link has a hollow body which has a pair of transverse surfaces extending transversely to the arrangement direction of the ornamental link.
  • One transverse surface defines a front surface of the jewel and the other transverse surface defines a back surface of the jewel.
  • the front face and the back face face 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 being opposed to each other.
  • each ornamental link has two locking tongues extending outwardly from the hollow body along the arranging direction from the front surface and provided on diametrically opposite sides of the first opening, respectively.
  • the two locking tongues are each provided with an elongated hole extending in the arrangement direction.
  • the decorative link has a radially inwardly projecting locking lug on an inner side/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 an assembly of decorative links has the advantage that the mobility of the decorative links relative to one another in the arrangement direction can be realized without side openings having to be provided in the side walls of the individual decorative links.
  • 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 filigree decorative links with a small wall thickness can also be realized.
  • an additional entry of dirt can be avoided since the side walls of the decorative elements, which run in the direction of arrangement, are not interrupted or perforated by side openings.
  • this type of coupling does not affect the external appearance of the individual decorative links, which increases the freedom of design.
  • the arranging direction corresponds to the direction in which the locking tongues of one ornament are inserted into the through hole of another ornament, or the axial direction of a straight bond or the circumferential direction of a circular (closed) bond.
  • the individual decorative elements can be identical, but they can also be different, as long as the individual decorative elements 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 decorative elements are positively connected to one another, they form a captive connection, independent of any support element (e.g. spring/thread/chain) that may be housed inside, which remains connected to one another even if the support element is damaged or tears.
  • any support element e.g. spring/thread/chain
  • Each ornamental link (including a final ornamental link) preferably has a rigid, i.e. plastically non-deformable, ornamental link body. From the link body in which the through hole for receiving the supporting member is provided, the locking lugs extend in the arranging direction. The locking lugs of one ornament are inserted into the through hole of another (preceding) ornament in a plastically bent state toward each other (insertion state). The locking lugs are plastically bent away from each other in comparison to the insertion state (connection state) for positively connecting the one ornament to the other (preceding) ornament.
  • the locking lugs are bent apart between the insertion state and the connection state by the action of an external force (not due to the material flexibility or restoring force inherent in them).
  • An advantageous embodiment of the disclosure envisages that the composite of decorative links that is guided through the through-holes of the decorative links, preferably elastic, supporting element, preferably in the form of a spring.
  • a support element stretches adjacent decorative links flat against one another, with the length or the diameter of the composite decorative link being able to be increased by stretching the elastic support element.
  • the composite of decorative links has the support element, the ability of the individual decorative links to be spread apart is supported.
  • the diameter or circumference of such a set of decorative links can also be individually adjusted to the desired part of the body on which the composite set of decorative links is to be worn with the aid of the support element, among other things.
  • the locking tongues of one decorative element can be bent plastically inwards before being inserted into the through hole of the other decorative element and can be bent plastically outwards after being inserted into the through hole of the other decorative element.
  • the jewelry links can be cast from precious metals such as gold.
  • the decorative links are cast with the locking tongues in their locking position and the locking tongues are plastically bent inwards or toward one another only before they are connected to another decorative link. Due to the plastic bending of the locking tongues of a jewelry link to each other, they can be easily and quickly inserted into the through hole of the other jewelry link. Through the subsequent plastic expansion of the locking tongues back to the initial state, the elongated holes of one jewelry link are easily and reliably engaged with the locking lugs of the other jewelry link and remain in this locking position for a long time due to a memory effect originating from the manufacturing process or casting.
  • first fastener may be coupled to the first ornament and a second fastener may be coupled to the last of the plurality of coupled ornaments, and the fasteners may be coupled to secure the coupled To be able to connect jewelry links to form a closed ring or closed circlet.
  • both the first closure element and the second closure element each have a through bore or transverse bore, which are aligned (with one another) when the closure elements are coupled to one another.

  • 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 ornamental link via the first and second locking pins is particularly secure.
  • the locking pins prevent the ends of the support element from loosening.
  • the locking pins prevent an undesired slipping of the support element within the ring/bracelet shape of the decorative link assembly.
  • the first locking member may have a first locking hollow pin protruding in the arranging direction for insertion into the through hole of the second locking member and the second locking member may have a second locking hollow pin protruding in the arranging direction for inserting into the through hole of the last ornamental link.

  • the fastener links 34,36 are of the same material as the ornamental links 2,38.
  • the locking members 34, 36 instead of the locking tongues 14, the locking members 34, 36 have a first and a second locking hollow pin 40, 42, respectively, which extends outwards in the arrangement direction A from the front face 22 of the first and second locking members 34, 36, respectively.
  • the locking hollow pins 40, 42 are preferably (material) integrally connected to the closure members 34, 36.
  • the through hole 12 of the first and second closure member 34, 36 continues in the first and second hollow locking pin 40, 42, respectively.
  • the first hollow locking 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 hollow locking pin 42 of the second closure member 36 is designed to be inserted into the through hole 12 of the last jewelry member 38 .
  • the diameter of the locking hollow pins 40, 42 is dimensioned such that it is only slightly smaller than the diameter of the through-channel 12 . Thus, the locking hollow pins 40, 42 can be inserted into the through hole.
  • the first hollow locking pin 34 has a first transverse bore 44 .
  • the second hollow locking pin 36 has a second transverse bore 46 .
  • the first and the second closure member 34, 36 differ from one another in that the second closure member 36 has a transverse bore 48 which is arranged transversely to the through hole 12 and the longitudinal surfaces 24, 25 of the second closure member 36 breaks through.
  • the second closure element 36 has no locking lugs 18.
  • 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 the longitudinal surfaces 24, 25 of the last decorative link 38 breaks through. In addition, in contrast to the other decorative links 2, the last decorative link 38 does not have any locking lugs 18.
  • the second fastener element 36 and the last ornamental element 38 are connected to each other, the second connecting hollow pin 42 of the second fastener element 36 is inserted into the through hole 12 of the last ornamental element 38 .
  • the second transverse bore 46 is aligned with the transverse bore 52 in the last ornamental link 38.
  • the second closure element 36 and the last ornamental 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 closure members 34, 36.
  • the arrows E indicate the direction in which the locking pins 50, 54 are used to couple the closure members 34, 38 of the last Jewelry link 38 and the ends of the support member 10 are inserted.
  • the locking tongues 14 of the first decorative link 2 are bent inwards or towards one another, starting from their initial state. Then the locking tongues 14 of the first decorative element 2 are inserted into the through hole 12 of the first closure element 34 so that the elongated holes 16 of the locking tongues 14 of the first decorative element 2 are aligned with the locking lugs 18 of the first closure element 18 . Then, the bending mandrel 32 is inserted into the through hole 12 of the first ornamental link 2 toward the first fastener link 34 . The locking tongues 14 of the first jewelry link 2 are then bent plastically 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 . This process is then repeated with the second decorative element 2 and a further decorative element 2 until the arrangement has the desired number of decorative elements 2 .
  • the support member 10 is inserted from the side of the first fastener 34 into the through hole 12 thereof and into the through holes 12 of all the ornamental links 2 up to and including the ornamental link 2 .
  • the second fastener link 36 is coupled to the final jewelry link 38 using the second locking pin 52 .
  • the last ornamental link 38 is coupled to the second end of the support member 10 by means of the second locking pin 52 in the manner described above.
  • the second locking pin 52 can be cohesively connected to the last decorative element 38, in particular by laser welding.
  • the support element 10 is then provisionally fixed with the first locking hollow pin 40 of the first closure element 34 under elastic pretension.
  • the free front surface of the first hollow locking 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 element or the decorative elements are made, forming 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 element 34 in such a way that the adjacent closure elements 34, 36 and decorative elements 2, 38 are elastically pretensioned in relation to one another in the direction of arrangement. 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 cohesively connected to the second closure element 36, in particular by laser welding.
  • decorative elements 6 can be fixed via the receiving sections 4 of the decorative elements 2, the last decorative element 38 and the first and second closure element 34, 36.
  • Figure 9A is a side view of a decorative link assembly 1 with a number x of decorative links 2.
  • the decorative link assembly 1 is in the relaxed state here shown. In the relaxed state, the front surface 22 of each decorative link 2 is in surface contact with the rear surface 23 of an adjacent decorative link 2.
  • Figure 9B 12 is a side view of the ornamental link assembly 1 taken from FIG Figure 9A was spread or widened. Due to the spreading, the diameter of the decorative link compound 1 increases. In the expanded state, the front surface 22 of a decorative link 2 and the rear surface 23 of an adjacent decorative link 2 no longer touch, but are spaced apart from one another.
  • Figure 9C is a side view of a decorative link assembly 1 with a number y of decorative links 2.
  • the number y of decorative links 2 in FIG Figure 9C illustrated decorative link assembly 1 is greater than the number x of decorative links 2 of the in Figure 9A illustrated decorative link compound 1.
  • the degree of inclination / curvature of the locking tongues 14 of the decorative links 2 of the decorative link assembly 1 in Figure 9A be larger than that of the decorative links 2 of the decorative link composite 1 in Figure 9C .
  • Figure 9D 12 is a side view of the ornamental link assembly 1 taken from FIG Figure 9C was spread or widened. Due to the spreading, the diameter of the decorative link compound 1 increases.
  • FIG. 10 is a perspective view of a multi-row decorative link assembly 1.
  • several, namely three, decorative links 2 are lined up in the transverse direction (ie transverse to the direction of arrangement) and are connected to one another, in particular cohesively. It is also conceivable that the decorative elements 2 are connected to one another in one piece of material in the transverse direction.
  • Two pairs of connecting pins 14 extend outwards in the arrangement direction from the front surface 22 resulting from the decorative links 2 arranged in a row in the transverse direction. This ensures that the decorative elements 2 can be connected to one another securely (positively) in the arrangement direction.
  • the method of assembling a single-row joint assembly 1 as above has been described is equivalent to a multi-row decorative link composite 1 applicable.
