Description:
JEWELLERY, GOLD JEWELLERY, SILVER JEWELLERY AND COSTUME JEWELLERY ARTICLE AN D METHOD OF PRODUCTION THEREOF D E S C R I P T I O N

Technical field

The present patent application belongs to the field of ornamental manufactured articles and, more specifically, to the accessories intended to be worn as a personal ornament.

More precisely, the present invention relates to a jewellery, gold jewellery, silver jewellery and costume jewellery article and to a method of production thereof.

BACKGROUND

Modular ornamental pendants, typically intended to be attached to chains, necklaces, brooches, earrings or other similar ornamental items, have been known for long time. Such modular pendants generally comprise two or more separate elements which may be functionally coupled together.

More specifically, known modular pendants consist of a flat shape, e.g. an anthropomorphic one, at least partially covered by a coating element, which, in case of the anthropomorphic shape, represents a female dress; this coating element is associated, by known means, with the shape itself so as to leave some room for movement between the dress and the shape. The final effect is greatly appreciated, since it seems like the dress is moving and floating around the body.

Generally, the shape has a hole, at the top of its head, suitable for engaging with connection means which allow to have the ornamental item suspended and to wear it.

In the known solutions of the type described above, the shape is formed by a metal foil or plaque, while the coating element generally consists of two coating metal foils or plaques.

The same metal foils or plaques face the front surface and the rear surface of the shape, respectively, so that the latter finds itself between them and then connected to each other, as well as to the shape, through nails, screws or rivets or other similar connection means.

In order to prevent the coating element from accidentally coming out of the shape, its forms and sizes are designed to interlock, in such a way as not to let it slip out.

Typically, the connection means comprise a male element and a female element which mutually engage, e.g. by screw or by pressure; generally, the female element is longer, since it has to pass through the three overlapping foils, while the male element is shorter and is long just as much as it is needed to engage effectively within the female part. Thus, once the two coating foils face the shape and are integrally connected to each other, the coating element can oscillate with respect to the shape, but cannot decouple from it.

Moreover, in the pendants of the known type, the distance between the two coating foils is slightly higher than the thickness of the shape, so that the coupling between the coating element and the shape is loose and allows the effect of a limited relative movement of the element representing the dress with respect to the shape.

This kind of loose coupling is particularly desired and appreciated, especially because it gives dynamism to the pendant, giving the impression of the movement of a dress in the event that an anthropomorphic shape is provided.

As said, in order to ensure a certain relative movement of the coating element, while preventing it from accidentally slipping out of the shape, the solutions known so far hence require the use of nails, screws, rivets or pins. However, the use of such connection means impacts the external appearance of the ornamental pendant, since the heads of the nails, rivets or screws remain entirely in view.

Moreover, the implementation of these nails, rivets or screws requires skilled labour and therefore affects the production cost of the manufactured article.

Therefore, there is the need to provide a modular ornamental pendant which is made up of elements that may be easily coupled together without using special tools or specific technical skills.

Moreover, there is the need to make the assembly operations easier, without the need for skilled labour and without having to weld, rivet or do anything else that could negatively affect the finishing of the items.

Objects and Summary of the Invention

A first object of the invention which is the subject-matter of the present patent application is to provide a pendant, e.g. representing an anthropomorphic shape, an animal, a tree or a figure portraying real or imaginary elements, at least partially covered by a coating element, the latter being partially movable with respect to the figure to be reproduced. A further object of the invention is to provide a pendant of the type described above which ensures a reliable and tested connection between the coating element and the anthropomorphic shape, so as to prevent one element from accidentally and unintendedly slipping out of the other one or of the shape itself.

Another object of the present invention is to provide a jewellery, gold jewellery, silver jewellery and costume jewellery article made up of a reduced number of components and therefore easy and inexpensive to produce.

A further object of the present invention is to provide a method for manufacturing an ornamental item which may be assembled without the need for skilled labour and which is totally free of welding, rivets or other connection means, with considerable advantages in the finishing of the items.

Another object of the invention is to provide a pendant which may be attached to necklaces, rings, brooches and other similar ornamental manufactured articles.

Last but not least, another object of the invention is to make a jewellery, gold jewellery, silver jewellery and costume jewellery by using readily commercially available means and commonly used materials, so that the device is economically competitive.

This task, as well as these and further objects that will become most apparent hereinafter, are achieved by a jewellery, gold jewellery, silver jewellery and costume jewellery article according to the invention, comprising:

- a support element extending along a development direction and having at least one section narrowing; - at least one foldable element suitable for being folded on itself along a folding line, such that said at least one folda ble element serves as a coating for at least a part of said support element;

- said at least one foldable element having a slot for connection with said at least one section narrowing, so as to prevent it from sli pping out along both ways of the development direction.

The folding line is substantially perpendicular with respect to the development direction.

Preferably, there is provided a connection hole with suitable connection means with other ornamental accessories or jewels, in such a way that the jewellery, gold jewellery, silver jewellery and costume jewellery article plays the role of a decorative pending element, e.g. which may be associated with chains, necklaces, brooches, earrings or other similar decorative items. Even more preferably, this connection hole is defined in the support element. Obviously, since there are provided section reductions, the support element comprises enlarged sections; each section narrowing is therefore defined between two subsequent enlarged sections.

Advantageously, the slot engages with at least one enlarged section of the support element. This enlarged section is located downstream of the section narrowing with respect to the aforementioned connection hole. In practice, the connection hole of the jewellery, gold jewellery, silver jewellery and costume jewellery article according to the invention is normally defined at the end of the support element which, during assembly and in standard use, is farther from the ground and, therefore, is the one that is less stressed by the gravitational force which, in this case, makes the weight of the foldable elements rest in the direction facing the end of the support element located downstream of the same connection hole.

Preferably, the slot engages both with the enlarged section located downstream of the section narrowing and with the one located upstream, so as to give more stability to the interlocking without the need of welding. Preferably, the slot is defined centrally on the foldable element, so that, in the case of symmetrical elements, the folding line coincides with a symmetry axis.

Advantageously, the slot may be longitudinal and elongated.

More specifically, in order to implement the interlocking between the support element and the foldable one, the slot has a longitudinal dimension greater than at least the maximum width of the closest upstream or downstream enlarged section and a transverse dimension greater than the width of the section narrowing. Moreover, at the same time, the transverse dimension of the slot is smaller than the maximum width of the enlarged section and also of a subsequent enlarged section defined on the support element, located downstream of the section narrowing.

The longitudinal and transverse dimensions of the slot refer to the dimension of the slot measured along the perpendicular with respect to the folding line of the foldable element and along the folding line itself, respectively.

It should be noted that both the support element and the foldable element could be plate-shaped, curved, modelled, moulded, microcast or other and therefore not be perfectly planar, but developed in three dimensions.

Preferably, the foldable element consists of a metal plate, suitable for being folded in such a way as to form two symmetrical folded parts defining two respective planes substantially parallel to each other.

The Applicant has realized that, in order to make folding easier, the plate is provided with at least one predetermined laminar hinge, extending along the folding line, through which it is suitable for being folded.

The laminar hinge or hinges are preferably defined within the inner part of the foldable element, wherein inner refers to the surface facing the surface of the support element after the folding step, so as to stay hidden from view when the jewellery, gold jewellery, silver jewellery and costume jewellery article is finished. The laminar hinges comprise straight transverse grooves which reduce the thickness of the foldable element and, consequently, the moment of inertia of the section remaining beneath the groove, so that, when a bending moment is applied, the material of the foldable element which is located at the groove is stressed more and reaches the plasticisation tension before the remaining material does; thanks to this effect, the relative rotation of the two elements, the fixed one and the foldable one, along the bending axis is obtained, without any room for error.

The transverse grooves may be produced using different techniques, e.g. using cold plastic deformation, shaving removal, laser, electrical discharge machining, etc., other forms of weakening of the section able to achieve the same technical result of making the mutual rotation easier are to be considered equivalent.

Advantageously, the Applicant has determined that, for the interlocking between the support element and the foldable element (or the foldable elements) to be effective, the foldable element must comprise a median portion, having a substantially rectangular shape, along whose long sides the two parts suitable for being folded are respectively connected.

Preferably, such median portion may have a width greater than the thickness of the support element, e.g. about 0.5 mm, so that the coupling between the foldable element and the support element is loose.

Median portion refers to a portion of the foldable element interposed between the two parts suitable for being folded.

The method for producing the jewellery, gold jewellery, silver jewellery and costume jewellery article according to the invention comprises the steps which, sequentially, consist of:

- inserting a slot, defined in a foldable element, into a section narrowing defined in a support element extending along a development direction, said foldable element being oriented in such a way that the longitudinal dimension of said slot passes through the portion with the maximum width of an enlarged section of said support element, located upstream or downstream of said at least one section narrowing,

the slot defined in a foldable element, on a section narrowing defined in a support element extending along a development direction, said foldable element being oriented in such a way that

- rotating said foldable element substantially by 90 degrees in such a way that the transverse dimension of said slot 3 interferes with at least one enlarged section downstream of that at least one section narrowing between enlarged sections defined on said support element, in order to block said foldable element with respect to the development direction of said fixed element, and

- folding said foldable element along a folding line defined on the median portion in such a way as to form two folded parts defining two respective planes substantially parallel to each other.

As said, "upstream" and "downstream" refer to the closest or the farthest end, respectively, with respect to the connection hole defined in the support element.

The longitudinal dimension of the slot has to pass through the portion with the maximum width of an enlarged section of the support element located upstream or downstream of the section narrowing, depending on user convenience and according to the form of the support element.

Preferably, the foldable element is rotated in such a way that the transverse dimension of the slot interferes with its closest enlarged sections located downstream and upstream of the section narrowing, so that the foldable element is interlocked between two subsequent enlarged sections.

Advantageously, if there are two or more foldable elements, for each of them the aforementioned sequence of steps will be repeated, in any order, provided that it is consistent with the form of the support element, without the need of assembling the various foldable elements so as to insert first those intended to couple with the reduced section of the farthest support element from the connection hole defined in the support element or, in any case, from one of the two end parts of the support element along its development direction.

In this case, then, the method continues with the following next steps, which may be repeated for all the other foldable elements to be assembled, consisting of:

- inserting at least one subsequent slot, defined in a subsequent foldable element, into a relative section narrowing defined in the support element, wherein the subsequent foldable element is oriented in such a way that the longitudinal dimension of the subsequent slot passes through the upstream and/or downstream enlarged sections, with respect to the relative section narrowing.

- rotating the subsequent foldable element, substantially by 90 degrees, in such a way that the transverse dimension of the subsequent slot interferes at least with the closest enlarged section with respect to the relative section narrowing, so that the foldable element is interlocked between two subsequent enlarged sections, and

- folding the subsequent foldable element along a folding line, defined on a respective median portion in such a way as to form two respective folded parts defining two respective planes substantially parallel to each other. Depending on how the support element is modelled, the relative subsequent enlarged sections may coincide with some of the enlarged sections.

Preferably, all the foldable elements are folded in such a way that the two folded parts end up near the support element.

To make folding easier, as already seen, the predetermined laminar hinge, which extends parallel to the folding line and is defined on the inner surface of the foldable element, is used.

Detailed Description of One or More Preferred Embodiments of the Invention With reference to the mentioned figures, there are shown four preferred embodiments of a jewellery, gold jewellery, silver jewellery and costume jewellery article, and of the method of production thereof, according to the invention, which is referred in its entirety as 101, 201, 501, and 601, and comprising:

- a support element 10, 30, 50, or 60 extending along a development direction 2 and having at least one section narrowing 13, 33, 50', 50", 50"',

50 IV , 60', 60", 60"', 60 IV and/or 60 v

- at least one foldable element 20, 40, 51, 52, 53, 54, 61, 62, 63, 64, and/or 65, suitable for being folded on itself along a folding line 7, so that it serves as a coating for at least part of the support element 10, 30, 50, or 60;

- the foldable element 20, 40, 51, 52, 53, 54, 61, 62, 63, 64, and/or 65 has a slot 3, 3', 3", 3"' and/or 3 IV for connection with the section narrowing 13, 33, 50', 50", 50"', 50 IV , 60', 60", 60"', 60 IV and/or 60^, so as to prevent it from slipping out along both ways of the development direction 2.

The support element 10, 30, 50 or 60 has a through hole 4 for connection with other pieces of jewellery or supports.

The support element 10 has the enlarged sections 11 and 12; the support element 30, instead, has the enlarged sections 31 and 32; as to the support element 50, instead, its enlarged sections are the following: 50a, 50a', 50a", 50a'" e SOa^; while enlarged sections 60a, 60a', 60a", 60a'", 608^ and 60a v , belong to the support element 60. Two subsequent enlarged sections define the relative section narrowing and, hence, as for the element 10 the section narrowing 13 is defined between the enlarged sections 11 and 12 (fig. 2A). As for the element 30, the section narrowing 33 is defined between the enlarged sections 31 and 32 (fig. 5). Taking the section narrowing 50" of the support element 550 as representative, it is defined by the two subsequent section narrowings 50a' (upstream) and 50a" (downstream) (fig. 8). For the sake of completeness, by way of example, the two subsequent enlarged sections 60a lv and eOa^, located upstream and downstream of the hole 4, respectively, define the section narrowing 60 v (fig. 10).

The slot 3, 3', 3", 3"' and/or 3 IV engages with a downstream enlarged section 12, 32, 50a', 50a", 50a'", 50a lv , 60a', 60a", 60a'", 60a lv or 60a and also with an upstream enlarged section 11, 31, 50a, 50a', 50a", 50a'", 60a, 60a', 60a", 60a'", 60a / / of the section narrowing 13, 33, 50', 50", 50"', 50 IV , 60', 60", 60"', m lv or W v .

In particular, the slot 3, 3', 3", 3"' and/or 3 IV has:

- a longitudinal dimension L greater than the maximum width of at least one of the enlarged sections 11, 12, 31, 32, 50a, 50a', 50a", 50a'", 50a lv , 60a, 60a', 60a", 60a'", 60a lv or 60a v ;

- a transverse dimension T greater than the width of the section narrowing 13, 33, 50', 50", 50"', 50 , 60', 60", 60"', 60 IV or 60" and at the same time smaller than the maximum width of at least one of the enlarged sections 11, 12, 31, 32, 50a, 50a', 50a", 50a'", 50alV, 60a, 60a', 60a", 60a'", 60alV, 60aV.

5 The foldable element 20, 40, 51, 52, 53, 54, 61, 62, 63, 64, and/or 65 consists of a foldable plate, so as to form two folded parts 22, 23, 42, 43, 51a, 51b, 52a, 52b, 53a, 53b, 54a, 54b, 61a, 61b, 62a, 62b, 63a, 63b, 64a, 64b, 65a and/or 65b defining two respective planes substantially parallel to each other.

10 The plate 20 and 40 above is suitable for being folded according to the laminar hinges 24' and 24", respectively (fig. 3A) or according to the single laminar hinge 44 (fig. 6). The hinges 24', 24" and 44, in any case, extend along the folding line 7. Each of them consists of a straight groove defined on the inner surface of the plate 20 and 40 so as to allow relative rotations

15 of the folded parts 22, 23, 42, or 43.

The foldable element 20, 40, 51, 52, 53, 54, 61, 62, 63, 64 and/or 65 comprises a median portion 21, 41, 51', 52', 53', 54', 61', 62', 63', 64' and/or 65' having a substantially rectangular shape and along whose long sides the two folded parts 22, 23, 42, 43, 51a, 51b, 52a, 52b, 53a, 53b, 54a, 54b, 61a,

20 62b, 62a, 62b, 63a, 63b, 64a, 64b, 65a and/or 65b are respectively connected.

The median portion 21, 41, 51', 52', 53', 54', 61', 62', 63', 64' and/or 65' has a width D greater by a few tenths of a millimetre than the thickness 14 of the support element 10, 30, 50, or 60, so that the coupling between the 5 foldable element 20, 40, 51, 52, 53, 54, 61, 62, 63, 64, and/or 65 and the element support 10, 30, 50, or 60 is loose.

In the first two embodiments of fig. 1-6, the jewellery, gold jewellery, silver jewellery and costume jewellery article 101 and 201 provides that the support element 10 or 30 is a substantially flat metal anthropomorphic

10 shape, defined at its top by an enlarged section 11 or 31 modelled as the head of the shape and connected at its bottom to the body 16 or 36 of the shape by a section narrowing 13 33 which is the neck of the shape itself. The foldable element 20 or 40, consisting of a metal plate 20 or 40 modelled as a substantially flat dress for the shape, whose median portion

15 21 or 41 having a substantially rectangular shape is interposed between the two foldable parts 22 and 23, or 42 and 43.

In the case of article 101, the connection between the median portion 21 and the parts 22 and 23 is established by the two respective laminar hinges 24' and 24", while as for the article 201 the connection between the median 0 portion 41 and the parts 42 and 43 is established by the single laminar hinge 44.

Other embodiments are possible wherein the anthropomorphic shape and/or the element representing the dress are not completely flat, but may have a more or less accentuated three-dimensional development.

As already stated, the inventive concept underlying the present invention may be applied to decorative items of various conformation, wherein the underlying shape and its coating element are not referred at all to an anthropomorphic shape, at least partially covered by an element representing a dress.

The element 20 or 40 has at its centre an elongated longitudinal opening 3, defined partially in its medial portion 21 or 41 and partially in each of its two end portions 22 and 23, or 42 and 43.

The outer surfaces of each end portion 22 and 23, or 42 and 43, and of the median portion 21 or 41 of the flat foldable element 20 or 40 may be painted or adorned with decorations of various kinds or may have one or more recesses 5 or other forms of decoration.

In the other two exemplary embodiments (fig. 7-10), the turtle 501 or the fish 601 have been made for the subsequent interlocking of the foldable elements 52, 53, 54, and 51, or 65, 64, 63, 62, and 61 on the respective fixed elements 50 or 60, and each of them is therefore made up of several foldable elements 51, 52, 53, and 54, or 61, 62, 63, 64, and 65, each of which partially contributes to cover the support element 50 or 60 to which, acting as a support, each foldable element 51, 52, 53, and 54, or 61, 62, 63, 64, and 65 is connected at the respective section reductions 50', 50", 50"' and S0 IV , or 60', 60", 60"', 60 IV , and 6Q V .

In order to couple the foldable element 20 or 40 to the support element 10 or 30, it is necessary firstly to arrange the foldable element 20 or 40 in a position substantially orthogonal to the plane on which the support element 10 or 30 lies, while ensuring that the longitudinal direction of the elongated longitudinal opening 3 is substantially aligned with the trace on the plane on which the support element 10 or 30 lies.

Thereafter, the slot 3 is passed through the section widen ing 11 (the head of the anthropomorphic shape), in the longitudinal direction, until the element 20 or 40 ends up substantially in correspondence with the section narrowing 13 (the neck of anthropomorphic shape). The longitudinal dimension L is slightly (a bout 1 mm) greater than the transverse dimension of the section widening.

At this point, it is necessary to rotate the elements 10 or 30, and 20 or 40 by about 90 degrees around the development direction 2 and therefore both the foldable parts 22 and 23, or 42 and 43 are folded along the laminar hinges 24' and 24"or along the single hinge 44, until the parts 22 and 23, or 42 and 43 reach the outer surface of the element 10 or 30, respectively. A similar procedure is followed for those jewellery, gold jewellery, silver jewellery and costume jewellery articles 501 or 601 consisting of several folda ble elements 51, 52, 53, 54, or 61, 62, 63, 64 and 65.

In order to produce the article 501, first of all it is provided to insert the slot 3 of the first element 52 onto the section narrowing 50", from the downstream end of the support element 50 with respect to the connection hole 4.

The foldable element 52 is oriented in such a way that the longitudinal dimension L of its slot 3 passes through the portion with the maximum width of the enla rged sections SOa'^, 50a'" and 50a", located downstream of the section narrowing 50".

Although the procedure substantially does not change even starting from the insertion of the slot 3 IV of the element 51 onto the section na rrowing 50', from the end which is closest to the hole 4, for sake of convenience it is preferred to assembly the foldable elements in the order: 52, 53, 54 and 51. Once the first element 52 has been arranged, the elements 53 and 54 are similarly positioned, sequentially, in the appropriate section reductions 50"' and S0 IV and then rotated by about 90°, again from the bottom according to the gravitational acceleration G indicated in figure 8, i.e., from the downstream end of the support element 50, that is the farthest one from the hole 4.

Before starting to fold them, the slot 3 IV of the foldable element 51 is inserted, being passed through the enlarged section 550a and, therefore, from above, i.e., from the upstream end of the support element 500.

Once the foldable elements 51, 52, 53 and 54 have been positioned, they are folded starting with the farthest one from the hole 4, i.e., the element 54, since, after the folding of the foldable elements 54, 53, 52 and 51 (listed in sequential order), it will have the respective folded parts 54a and 54b at least partially covered by the folded parts 53a and 53b of the foldable element 53, which in turn are at least partially covered by the folded parts 52a and 52b of element 52. The latter parts 52a and 52b are also at least partially covered by the folded parts 51a and 51b of the element 51, the closest one to the connection hole 4.

The foldings, carried out according to the aforementioned sequence, are performed along the relative folding lines 7, each defined on the respective median portions 54'-51', so as to form the pairs of folded parts 54a/54b, 53a/53b, 52a/52b and 51a/51b, each pair defining two planes substantially parallel to each other. As already seen for the articles 101 and 201, as well as for the article 501, the folding will ensure that the edges of the parts 54a/54b, 53a/53b, 52a/52b and 51a/51b end up near the support element 50.

As far as the production of the article 601 is concerned, instead, once the slot 3 of the foldable element 65 has been suitably inserted into the section 60 v , from above according to the gravitational acceleration G indicated in figure 10, i.e., from the upstream end of the support element 60, that is the closest one to the hole 4, while carefully orienting it in such a way that the longitudinal dimension L of its slot 3 passes through the portion with the maximum width of the enlarged sections 60a, 60a', 60a", 60a'" and 60a lv , all located upstream of the section narrowing 60^, the element 65 is rotated by about 90° and then folded along the line 7 in its median portion 65' so that the two parts 65a and 65b, after folding, end up on planes substantially parallel to each other.

Likewise, the other foldable elements 64, 63, 62 and 61, in this order, are positioned in the respective section reductions 60^, 60"', 60" and 60', rotated by about 90° and folded.

The folds, carried out according to the same aforementioned sequence (65, 64, 63, 62, 61), are performed along the relative folding lines 7, each defined on the respective median portions 64'-61', so as to form the pairs of folded parts 64a/64b, 63a/63b, 62a/62b and 61a/61b, each pair defining two planes substantially parallel to each other.

Here again, the folding will ensure that the edges of the parts 65a/65b, 64a/64b, 63a/63b, 62a/62b and 61a/61b end up near the support element 60.

In the embodiments considered here to produce the articles 501 and 601, no laminar hinges have been made to make folding easier, since the production of such hinges for many pieces (four foldable elements for the article 501 and five for 601) increases labour costs and, in the case of thin metal plates such as 51, 52, 53 and 54, or 61, 62, 63, 64 and 65, weakens the metal.

From the above description, it is thus clear how the invention achieves the intended aim and objects and, especially, it is underlined that a jewellery, gold jewellery, silver jewellery and costume jewellery article is created, as well as a method of production thereof, which allows to create a pendant or other manufactured item in a modular way.

More specifically, the loose interlocking of the foldable elements on the support element, such that they turn to be partially movable with respect to the figure to be reproduced, allows the production of a novel alternative compared to the prior art. Another advantage of the invention lies in the fact that the interlocking system ensures a reliable and tested connection between the elements constituting the jewellery, gold jewellery, silver jewellery and costume jewellery article, so as to prevent one element from accidentally and unintendedly slipping out of the other one or of the shape itself.

In this regard, since according to the method for producing these decorative items they may be assembled without the need for skilled labour and without any need for welding, rivets or other connection means, there are provided considerable advantages in the finishing of the items.

Moreover, the limited number of components, as well as the little labour required to produce this article, makes the manufactured articles, according to the invention, easy and inexpensive to produce.

Not least, the use of readily commercially available means and the use of common materials make the device economically competitive.

The so-designed invention is susceptible of numerous modifications and variations, all of which fall within the scope of the inventive concept.

Further, all the details will be replaced by other technically equivalent elements.

In practice, the materials employed, as well as the dimensions, may be different according to requirements, provided they are consistent with the realization purpose.
