[0001] The present invention relates to an enameling of a jewelry and / or precious metal article.
[0002] The invention also relates to a jewelry and / or precious metal article comprising such an interlocking, in particular to form a fringe.
[0003] The invention also relates to a method for manufacturing an enamel, particularly for forming a fringe of a jewelry article. Prior art
[0004] Jewelry and / or precious metalwork articles of the chain type are known, comprising an interlocking structure formed by a plurality of links, each link being engaged with another link. These may be, for example, rings held together and soldered, or connected to each other by interface elements such as hinges and comprising, for example, connecting axles or pins. Description of the invention
[0005] The invention aims to provide an mesh for a jewellery and / or jewelry article, which is particularly simple and convenient, especially for assembly.
[0006] The invention thus relates, in a first aspect, to an interlocking of a jewelry and / or precious metal article, comprising at least one first link and at least one second link mechanically attached to the at least one first link, each of the at least one first link and of the at least one second link comprising an ornamental element and a cradle configured to receive the ornamental element in an internal receiving space of the cradle and comprising an assembly notch formed at a first end of the cradle and opening into the internal space, and an assembly head extending in projection from a second end of the cradle, opposite its first end, and outside the internal space of the cradle;with the linking which is formed by the at least partial insertion of the assembly head of at least one first link into the internal space of the cradle of at least one second link through its assembly notch and by the ornamental element which comes opposite the assembly head of at least one first link and which is set into the internal space of the cradle of at least one second link. ;
[0007] In the meshing according to the invention, it is therefore simply the cooperation between a first link, a second link and an ornamental element which allows the mechanical fastening of the first link with the second link.
[0008] In other words, in addition to having an ornamental role, the ornamental element also has a predominant role in the mechanical fastening of the first link with the second link since it is the one which holds the assembly head of the first link in the internal space of the second link through its assembly notch, and this simply by crimping the ornamental element in the internal space of the cradle of the second link.
[0009] Other particularly simple and convenient features of the meshing according to the invention are described below.
[0010] Each cradle has a rear wall at its first end, a front wall at its second end which is opposite the rear wall, and two side walls facing each other and each joining the rear wall and the front wall at the first and second ends, with the assembly notch which is provided in the rear wall, the assembly head which protrudes from the front wall and the internal space which is delimited between the rear wall, the front wall and the side walls.
[0011] Each cradle has a top opening for inserting the ornamental element into the internal space, and a bottom assembly opening, opposite the top opening, for passing the assembly head through the assembly notch.
[0012] Each assembly head is provided with a tenon projecting from the cradle and a stop member provided at a free end of the tenon.
[0013] Each assembly head is provided with a recess formed on the tenon upstream of the stop member.
[0014] The cradle of at least one second link rests on the recess made on the tenon of the assembly head of at least one first link when the latter is assembled with at least one second link.
[0015] When at least one first link is assembled with at least one second link and with the ornamental element, the latter rests on the stop member of the assembly head of at least one first link.
[0016] Each cradle has at least one guide element provided in the internal space and in the immediate vicinity of the assembly notch.
[0017] When at least one first link is assembled with at least one second link and with the ornamental element, the tenon of the assembly head of at least one first link is slid against at least one guide member provided in the internal space and its stop member rests on at least one guide member of the cradle.
[0018] The ornamental element of the second link has a heel configured to be inserted into the internal space of the cradle so as to form a retaining stop for the assembly head of the first link, and a cradle cover plate surmounting the heel.
[0019] The invention also relates, in a second aspect, to a jewelry and / or precious metal article, comprising an inlay as described above, in particular to form a fringe of the article.
[0020] The invention also relates, in a third aspect, to a method for manufacturing an enameling as described above, in particular for forming a fringe of a jewelry article and / or precious metalwork, comprising the steps of:
[0021] - provide at least one first link and at least one second link, comprising each a cradle configured to receive the ornamental element in an internal space for receiving the cradle and having an assembly notch made at one first end of the cradle and opening into the internal space, and an assembly head extending in projection from a second end of the cradle, opposite its first end, and outside the internal space of the cradle;
[0022] - provide at least one ornamental element;
[0023] - insert the head of at least one first link into the internal space of the cradle of at least a second link through its assembly notch;
[0024] - introduce the ornamental element into the internal space of the cradle of at least one second link opposite, in particular in the immediate vicinity, of the assembly head of at least one first link and set the ornamental element in the internal space of the cradle of at least one second link.

[0037] Figures 1 and 2 show an mesh 20, in particular of a jewelry and / or precious metal article.
[0038] The mesh 20 comprises several links 1 assembled and fastened to each other.
[0039] The links 1 are here aligned and form a mesh 20 that is substantially straight and relatively rigid.
[0040] The links 1 of the mesh 20 each comprise a cradle 2 having a first end and a second end opposite to the first end.
[0041] Each link 1, for example called the first link, is configured to be assembled, or coupled, by the first end of its cradle 2 to another link 1, for example called the second link, by the second end of its cradle 2.
[0042] The cradle 2 of each link 1 includes an assembly head 12 configured to be inserted into the cradle 2 of another adjacent link 1.
[0043] Each link 1 also includes an ornamental element 3, provided with a heel 18 and a cover plate 17 and set on the cradle 2.
[0044] In the mesh 20, each ornamental element 3, except one at one end of the mesh, is configured to serve as a locking element for the assembly of two links together.
[0045] Figures 3 to 5 show in more detail one of the links 1 of the mesh 20.
[0046] The cradle 2 has a rear wall 5 at a first end, a front wall 6 at a second end opposite the first end, and two side walls 7 and 8 joining respectively the rear wall 5 and the front wall 6.
[0047] The front wall 6 is opposite the rear wall 5 and the two side walls 7 and 8 are opposite each other.
[0048] The cradle 2 further comprises an internal receiving space 4 delimited by the rear wall 5, the front wall 6 and the two side walls 7 and 8.
[0049] The front, rear and side walls define a top opening for the introduction of an ornamental element 3, and a bottom assembly opening for the passage of an assembly head 12.
[0050] The upper introduction and lower assembly openings are located at least partially opposite each other and open into the internal receiving space 4.
[0051] In the remainder of this document, a dimension in a front-to-back direction is called length and a dimension in a lateral direction is called width. A dimension in a third direction orthogonal to the first two directions is called height.
[0052] The front, rear and / or side walls may be substantially rectangular in shape.
[0053] The front, rear and / or side walls can be arranged substantially at right angles, the cradle being substantially parallelepiped in shape.
[0054] The rear wall 5 and the front wall 6 are higher than the side walls 7 and 8 and protrude at the level of the upper opening.
[0055] The side walls 7 and 8 have edges 9 and 10 at the level of the upper opening which define support areas for the ornamental element 3, between the rear wall 5 and the front wall 6.
[0056] The cradle 2 includes an assembly notch 11 formed in the rear wall 5.
[0057] The notch 11 passes through the rear wall 5 and opens here into the internal space 4 and into the lower opening.
[0058] The cradle 2 includes an assembly head 12 extending projecting from the front wall 6, from an external face of the front wall 6 and outside the internal space 4.
[0059] The assembly head 12 extends here in projection substantially at a right angle from the front wall 6.
[0060] The assembly head 12 includes a tenon 13 projecting from the front wall 6 and a stop member 14 at the level of a free end of the tenon 13.
[0061] For example, the tenon 13 extends here from an area of the front wall 6 at the level of the lower opening, up to about half a height of the front wall 6, and the tenon 13 for example has a width that corresponds approximately to the width of notch 11.
[0062] The stop member 14 is disposed on an upper face of the tenon 13.
[0063] For example, the stop member 14 is located here substantially opposite and at mid-height of the front wall 6.
[0064] In the illustrated example, the stop member 14 is wider than the tenon 13 on which it is formed.
[0065] The stop member 14 is however in the illustrated example significantly narrower than the lower opening of the cradle 2, that is to say that its width is here less than a distance separating the side walls 7 and 8.
[0066] The tenon 13 is here provided with a recess 15 made upstream of the stop member 14.
[0067] The section of the tenon 13 at the recess 15 can be of complementary shape to the shape of the notch 11. When the notch 11 is substantially rectangular, the section of the tenon 13 at the recess 15 is substantially rectangular.
[0068] The recess 15 is provided at a distance from the front wall 6 and can extend to the stop member 14.
[0069] As can be seen later, the distance from the recess 15 to the front wall 6 defines the spacing between the front wall 6 of one cradle 2 and the rear wall 5 of another adjacent cradle 2 when the two cradles 2 are assembled.
[0070] The cradle 2 further includes an internal guide element 16.
[0071] The guide element 16 is here formed by an overthickness on each of the lateral walls 7 and 8.
[0072] The extra thickness extends over a limited portion of the side walls 7 and 8, in the immediate vicinity of the notch 11.
[0073] For example, the extra thickness extends over approximately between one third and one half of the width of a side wall 7 and 8.
[0074] The extra thickness also extends over about half the height of a side wall 7 and 8.
[0075] The cover plate 17 of the ornamental element 3 is substantially rectangular, with a width corresponding substantially to the width of the cradle 2, and a length corresponding substantially to a distance between the respective internal faces of the front 6 and rear 5 walls of the cradle 2.
[0076] The cover plate 17 surmounts the heel 18 which therefore protrudes from an underside face of the cover plate 17.
[0077] The heel 18 is for example formed by a substantially rectangular parallelepiped block.
[0078] The height of the heel 18 is such that the total height of the ornamental element 3 is here less than or equal to the height of the cradle 2.
[0079] The width of the heel 18 corresponds approximately to the distance between the side walls 7 and 8 of the cradle 2, that is to say approximately to the width of the lower opening.
[0080] The length of the heel 18 corresponds substantially to the length of the lower opening reduced by the length of the guide member 16.
[0081] The ornamental element 3 may also include, at the level of an upper face of the cover plate 17, one or more relief elements 19.
[0082] For example, when the ornamental element 3 is a precious or semi-precious stone, the upper face of the cover plate 17 can be cut so as to reveal decorative relief elements 19.
[0083] The cradle 2 and the ornamental element 3 can each be made in one piece.
[0084] The cradle 2 can for example be made of a metallic material, for example a precious material such as gold, silver or platinum.
[0085] The ornamental element 3 can be made of a semi-precious or precious stone, such as spinel, diamond, ruby, etc., or of mother-of-pearl, glass, a precious metal, etc.
[0086] We will now describe the assembly of two links 1, that is to say the linking of a first link with a second link, with reference to figures 6 to 11 which show several stages of this assembly.
[0087] In [Fig.6], the first link and the second link are arranged so that the cradles 2 are placed substantially at right angles to each other, with the first end of the cradle 2 of the first link opposite the second end of the cradle 2 of the second link.
[0088] In particular, the assembly head 12 of the first link is arranged opposite the lower opening of the cradle 2 of the second link.
[0089] On [Fig.7], the assembly head 12 of the first link is introduced through the lower opening into the internal space 4 of the cradle 2 of the second link.
[0090] On [Fig.8], the cradle 2 of the first link is moved in translation so that its assembly head 12 is brought closer to the rear wall 5 of the cradle 2 of the second link.
[0091] In this position, the tenon of the assembly head is at least partially guided between the guide member in the cradle.
[0092] On [Fig.9], the cradle 2 of the first link is moved in rotation so that the front wall 6 of the cradle 2 of the first link is opposite the rear wall 5 of the cradle 2 of the second link.
[0093] In this position, the lower face of the stop member 14 of the head 12 The assembly of the cradle 2 of the first link rests on the guide member 16, and the tenon 13 is housed between the guide member 16 and in the notch 11 of the cradle 2 of the second link.
[0094] The cradle 2 of the second link rests on the tenon 13 of the assembly head 12 of the first link, with for example the bottom of the notch 11 of the cradle 2 of the second link coming substantially into contact with the bottom of the recess 15 on the tenon 13 of the assembly head 12 of the first link.
[0095] Part of the internal space 4 of the cradle 2 of the second link is thus occupied by the assembly head 12 of the cradle 2 of the first link.
[0096] A relative movement of the cradles 2 of the first and second links in the vertical direction of the cradles 2 is thus restricted.
[0097] A relative movement of the cradles 2 of the first and second links in the lateral direction and in the lateral direction of the cradles 2 is also restricted
[0098] On [Fig.9], the ornamental element 3 of the second link is also brought close to the cradle 2 of this second link and in particular the ornamental element 3 is intended to come opposite and in the immediate vicinity, but not necessarily in direct contact, with the stop member 14 of the assembly head 12 of the cradle 2 of the first link.
[0099] On [Fig. 10], the ornamental element 3 of the second link is introduced through the upper opening into the internal space of the cradle 2 of the second link, with a portion of the lower face of the cover plate 17 which comes opposite and in the immediate vicinity of an upper face of the stop member 14 of the assembly head 12 of the cradle 2 of the first link 1, another portion of the lower face of the cover plate 17 which comes to rest on the bearing areas formed by the upper edges 9 and 10 of the lateral walls 7 and 8, and the heel 18 of the ornamental element 3 of the second link which occupies a part of the internal space 4 of the cradle 2 of this second link, which is not already occupied by the assembly head 12 of the cradle 2 of the first link.
[0100] The cover plate 17 of the ornamental element 3 of the second link 1 is thus arranged between the rear wall 5 and the front wall 6 of the cradle 2 of the second link 1. Here, it does not protrude laterally from the side walls 7 and 8.
[0101] The heel 18 of the ornamental element 3 of the second link forms a stop against the assembly head 12 of the cradle 2 of the first link, which prevents the first link 1 and the second link 1 from moving relative to each other in the axial direction.
[0102] On [Fig. 11], the ornamental element 3 of the second link is set in the cradle 2 of this second link.
[0103] In particular, in the illustrated example, the front and rear walls 6 and 5 of the cradle 2 of the second link have upper edges that are deformed and folded over the cover plate 17 of the ornamental element 3 of the second link for holding it in position.
[0104] The preceding description of the assembly of two links can therefore be repeated for the assembly of other links, for example to obtain the linking of figures 1 and 2 and in particular here to form a fringe of a jewellery and / or jewelry article, in particular of the pendant type or any other article.
[0105] For example, it could be a necklace, a breastplate, a cuff, a bracelet, etc.
[0106] It should be noted that an interlocking such as described above is particularly simple and convenient to implement.
[0107] It is more generally recalled that the invention is not limited to the examples described and represented.
