Description

The present invention relates to a jewellery item and to a method for connecting modular elements to obtain such jewellery item.

In particular, the present invention relates to a jewellery item comprising a plurality of modular elements connected to each other so as to make the jewellery item an item of variable dimensions.

Methods for connecting modular elements to manufacture jewellery items of variable dimensions and relative jewellery items are known.

Items of this type are for example described in DE9100430 or in EP1911366.

Such documents disclose jewellery items which, starting from a closed (or contracted) configuration to an open (or extended) configuration, vary the dimensions of the item itself.

However, such items have the drawback lying in the fact that, in the open configuration, they are fragile, i.e. susceptible to shape variation during use as well as breakage in case of impact.

Furthermore, though aesthetically pleasant in the closed position, they are not aesthetically satisfactory in the open position thereof.

Another drawback of such known items is related to the fact that, being scarcely robust, they hardly maintain the intermediate positions between the maximum open one and the maximum closed one, but they tend to acquire one of these two positions, thus resulting of non-modular dimensions.

The object of the present invention is therefore to provide a jewellery item of variable dimensions that is resistant and aesthetically pleasant even at an open or extended position.

A further object of the present invention is to provide a method for connecting modular elements to obtain a jewellery item of variable dimensions that is simple, economical and allowing obtaining a resistant and pleasant item in all possible configurations thereof.

A further object of the present invention is to allow the modularity of the dimensions of a jewellery item, making it adaptable to different users in terms of dimensions and taste.

These and other objects are attained by means of a jewellery item comprising a plurality of modular elements in which at least one of such modular elements comprises:

• • at least three connection points for connection to three further modular elements, the connection point being suitable for connecting said at least one modular element to a further modular element; and
  • at least one intermediate portion, interposed between a first connection point for connection to a first further modular element and a second connection point for connection to a second further modular element of said three connection points, said at least one intermediate portion being configured so as to allow the interposition of a further fourth element between said further first modular element and said further second modular element;

in which said at least one modular element is connected to said three further modular elements and operatively associated with said further fourth modular element so as to allow the jewellery item to pass from a contracted configuration to an extended configuration varying the dimensions thereof.

The combination of such characteristics allows obtaining a jewellery item that is resistant and aesthetically pleasant in each configuration thereof.

In particular, the interposition of a further modular element, operatively associated with the modular element, between the two further modular elements connected to the same modular element, helps to create a compact structure with high resistance to deformations and impacts and aesthetically pleasant.

According to a preferred embodiment of the invention, the intermediate portion comprises a further connection point for connection to said further fourth modular element.

In this way, the modular element is also connected to such further modular element and the item is even more resistant.

Advantageously said modular elements are identical to each other and said further modular elements are identical to each other and/or are identical to said modular elements with obvious manufacture advantages.

Alternatively, they are different to each other, with advantages in terms of the different aesthetic solutions that can be obtained therewith.

Preferably, said modular elements belong to the same plane α and said further modular elements belong to the same plane β parallel to the plane α.

According to preferred embodiments, said intermediate portions are two: a first one interposed between the first connection point for connection to the further first modular element and the second connection point for connection to the further second modular element and configured so as to allow the interposition of the further fourth modular element between said further first modular element and said further second modular element; and a second one interposed between the second connection point for connection to the further second modular element and a third connection point for connection to a further third modular element and configured so as to allow the interposition of a further fifth modular element between said further second modular element and said further third modular element.

Preferably, said modular elements are connected with said further modular elements at said connection points through rotation pins.

Advantageously said connection points comprise through holes.

Preferably, the jewellery item further comprises housings adapted to receive gems or other decorative elements.

Thus, the aesthetic aspect of the item is improved.

Advantageously, said housings are located at each connection point and/or at each intermediate area.

Preferably, said modular elements and/or said further modular elements are oblong-shaped.

According to a second aspect thereof, the invention relates to a method for connecting modular elements to obtain a jewellery item of variable dimensions comprising the steps of:

a. connecting a modular element to at least three further modular elements at the corresponding three connection points thereof;

b. interposing at least one further modular element between two of said three further modular elements connected to the modular element, so that such interposed further modular element is operatively associated with the modular element at an intermediate area thereof.

Such method is simple, economical and achieves the object of manufacturing jewellery items that are resistant, of variable dimensions and aesthetically pleasant.

Preferably said step b comprises the interposition of two further modular elements, each of said two further modular elements is interposed between two of said three further modular elements connected to the modular element.

With reference to FIGS. 1-14, a jewellery item according to the present invention, is generally indicated with reference number 1.

The jewellery item 1 comprises a plurality of modular elements 2 in which at least one of such modular elements 2 comprises at least three connection points 3a, 3b, 3c for connecting to three further modular elements 2a, 2b, 2c, in which connection point 3a, 3b, 3c is suitable for connecting said at least one modular element 2 to a further modular element 2a, 2b, 2c.

According to the present invention, the jewellery item 1 further comprises at least one intermediate portion 4, which is interposed between a first connection point 3a and a second connection point 3b of said three connection points 3a, 3b, 3c. Such intermediate portion 4 is configured so as to allow the interposition of a further fourth modular element 2d between said further first modular element 2a and said further second modular element 2b.

In other words, a modular element 2 comprises at least four portions, of which three connection portions and a portion for the interposition of further modular elements 2d, 2e.

The modular element 2 is connected to said three further modular elements 2a, 2b, 2c and operatively associated with said further fourth modular element 2d so as to allow the jewellery item 1 to pass from a contracted configuration to an extended configuration varying the dimensions thereof.

In other words, the combination of the above mentioned features allows the modular elements 2 to vary the mutual position thereof passing from a contracted position in which, should the item be circular-shaped, for example a ring, a bracelet, a watch strap, the diameter is minimum, to an extended position in which the diameter is maximum.

The passage from the contracted position to the extended position and vice versa can also be modulated, hence the item 1 may acquire all the intermediate positions between such two extreme positions and remain in such intermediate positions, due to the specific configuration and robustness of the structure.

As a matter of fact, the abovementioned configuration, allows obtaining a quadrilateral system with articulable vertices which are mutually constrained not only at the vertices, as in the items of the prior art, but also at other quadrilateral portions.

The intermediate portion 4 may serve as a bridge between two connection points 3a, 3b, 3c and let the further fourth modular element 2d slide thereon without being fixed thereto, or comprise a further connection point for connection to said further fourth modular element 2d.

According to the embodiments shown in FIGS. 3a-3d, 4a-4d, 5a-5d, 6a-6d, 7, 7a, 7b, 8, 8a, 8b, 13, the modular elements 2 and the further modular elements 2a, 2b, 2c are all identical to each other, but they could be different.

As visible in the figures, said modular elements 2 belong to the same plane α and said further modular elements 2a, 2b, 2c belong to the same plane β parallel to the plane α.

According to the embodiments shown in FIGS. 1b-1d, 2a, 2b, 7, 7a, 7b, 8, 8a, 8b, 13 and 14, there are two intermediate portions 4: a first interposed between the first connection point 3a for connection to the further first modular element 2a and the second connection point 3b for connection to the further second modular element 2b and configured so as to allow the interposition of the further fourth modular element 2d between said further first modular element 2a and said further second modular element 2b ; and a second one interposed between the second connection point 3b for connection to the further second modular element 2b and a third connection point 3c for connection to a further third modular element 2c and configured so as to allow the interposition of a further fifth modular element 2e between said further second modular element 2b and said further third modular element 2c.

According to the illustrated embodiments, the modular element 2 and the further modular elements 2a, 2b, 2c, 2d, 2e are oblong-shaped.

In particular, the modular element 2 of FIG. 1a comprises four circular portions arranged along an axis to form an oblong element. Three of such four portions coincide with the connection points 3a, 3b and 3c and one of such circular portions coincides with the intermediate portion 4.

Each of such circular portions comprises a through-hole adapted to connect the modular element 2 with further modular elements 2a, 2b and 2c through rotation and/or joint pins.

However, the modular element 2 is not necessarily connected in four points to further modular elements 2a, 2b, 2c, 2d, 2e. Actually, the intermediate portion 4 may comprise or not comprise connection points.

The modular element 2 of FIG. 1b comprises five circular portions arranged along an axis to form an oblong element. Three of such five portions coincide with the connection points 3a, 3b and 3c and two of such circular portions coincide with intermediate portions 4.

Each of such circular portions comprises a through-hole adapted to connect the modular element 2 with further modular elements 2a, 2b and 2c through rotation and/or joint pins.

However, analogously to the previous case, the modular element 2 is not necessarily connected in five points to further modular elements 2a, 2b, 2c, 2d, 2e.

The modular element 2 of FIGS. 1c, 1d, 2a and 2b comprises three circular portions, coinciding with the connection points 3a, 3b and 3c, which are connected by two rectilinear (in FIGS. 1c and 1d) or curvilinear (in FIGS. 2a and 2b) elements, which coincide with connection portions 4, to form an oblong element.

Each of such circular portions comprises a through-hole adapted to connect the modular element 2 with further modular elements 2a, 2b and 2c through rotation and/or joint pins.

Also the rectilinear elements in FIG. 1c and the curvilinear elements in FIGS. 2a and 2b comprise through-holes, usable, possibly for the connection of the modular element 2 to the further modular elements 2a, 2b and 2c.

The modular elements 2 of FIGS. 2a and 2b comprise elements 8 that may be collets or shims and which may have aesthetic functions.

Such elements 8 are preferably integral with the modular elements 2.

As previously mentioned, the modular elements 2 are connected with said further modular elements 2a, 2b, 2c at said connection points 3a, 3b, 3c through pins.

In the preferred embodiments, the jewellery item 1 further comprises housings 5 adapted to receive gems 6, as visible from FIGS. 11 and 12, or other decorative elements for example closing caps, not shown in the figures, which may be suitably machined.

Such housings 5 may be integral with the connection pin 7.

In such case, the aforementioned through-holes also serve the function of aligning such housings 5.

The through-holes can have different shapes, according to the requirements.

FIGS. 9 and 10 show two different variants of housing 5. However, they may be of any known type suitable for such purpose.

In the embodiments shown in FIGS. 7 and 8, said housings 5 are located at each connection point 3a, 3b, 3c.

On the contrary, in the embodiments shown in FIGS. 3a, 3b, 4a, 4b, 5a, 5b, 6a, 6b said housings 5 are located at each connection point 3a, 3b, 3c and at each intermediate area 4.

FIGS. 3 c and 3d show simplified views of FIGS. 3a and 3b. Analogously, FIGS. 4c and 4d show simplified views of FIGS. 4a and 4b.

In other words, FIGS. 3c, 3d, 4c and 4d show a single modular element 2 and the further modular elements 2a, 2b, 2c, 2d to which it is connected and/or operatively associated with after the assembly is completed.

Analogously, FIGS. 7a, 7b, 8a, 8b, 13, 14 show a single modular element 2 and the further modular elements 2a, 2b, 2c, 2d, 2e to which it is connected and/or operatively associated with after the assembly is completed.

The portions of jewellery item 1 illustrated in FIGS. 3a-3d, 4a-4d, 5a, 5b, 6a, 6b are obtained with the modular element 2 of FIG. 1a.

The portions of jewellery item 1 illustrated in FIGS. 7, 7a, 7b, 8, 8a, 8b are obtained with the modular element 2 of FIG. 1c.

The portions of jewellery item 1 illustrated in FIGS. 13 and 14 are obtained with the modular element 2 of FIG. 1d.

The modular elements 2 and the further modular elements 2a, 2b, 2c, 2d, 2e may be arranged on a portion of the item 1 or on the entire item 1.

Said jewellery item 1 is preferably a ring, but it may be any ornament of the known type and of any shape (flat, concave, convex, curvilinear, etc.).

Obviously, the invention is extended to items of jewellery, silverware, costume jewellery and the like, without requiring modifications.

The jewellery item 1 may be made of any material deemed suitable.

Following is the description of a method for connecting modular elements 2 to obtain a jewellery item 1 of variable dimensions, according to the present invention.

According to a first step a, the method provides for connecting a modular element 2 to at least three further modular elements 2a, 2b, 2c at corresponding three connection points 3a, 3b, 3c thereof.

Subsequently, the method of the invention provides for a step b of interposition of at least one further modular element 2d, 2e between two of said three further modular elements 2a, 2b, 2c connected to the modular element 2, so that such interposed further modular element 2d, 2e is operatively associated with the modular element 2 at an intermediate area 4 thereof.

Preferably, said step b comprises the interposition of two further modular elements 2d, 2e, each between two of said three further modular elements 2a, 2b, 2c connected to the modular element 2.

A step c of connecting the interposed further modular elements 2d, 2e to the modular element 2 may be provided for.

Preferably the step a is actuated through pins positioned at the connection points 3a, 3b, 3c and, when present, also the step c may be actuated in the same manner.

Preferably, the pins are inserted into specific through-holes present at the connection points 3a, 3b, 3c and the projecting bases thereof are casted with the further modular elements 2a, 2b, 2c.

Obviously, the jewellery item and the production process thereof according to the present invention may be subjected—by the man skilled in the art with the aim of meeting contingent and requirements—to further modifications and variants, all falling within the scope of protection of the present invention.
