Description

Title of the invention: Jewelry item comprising a setting bearing a decorative element, the setting being removably mounted on a setting by magnetization. Technical field of the invention

[0001] The invention relates to the field of jewelry articles such as jewelry and / or sets, or other similar ornamental articles. The invention relates more specifically to such jewelry articles comprising a setting which carries a decorative element and which is removably mounted by magnetism on a setting, to allow an individual to interchange on the same setting settings carrying different decorative elements. Prior art

[0002] In the field of jewelry articles, it is common for at least one decorative element to be installed on a setting via a setting bearing the decorative element. In such a context, the decorative element is firmly held on the setting at its upper end, the setting bearing the decorative element forming a cohesive whole which is itself installed on the setting via its lower end.

[0003] It is now necessary to clarify that the concepts upper and lower - or other related concepts such as for example base and top or overhang, riser and bottom - are relative concepts considered according to a direction of mounting of the setting on the frame opposite to a direction of removal of the setting from the frame following a unidirectional assembly direction between them.

[0004] According to current methods, the setting has at its upper end a blind cavity receiving the decorative element. The decorative element is held inside the cavity of the setting which receives it, such as by close fitting, by sealing inside the cavity and / or by crimping at the outlet of the cavity. It is also known to provide the setting with a claw structure for holding the decorative element which is arranged overhanging the setting.

[0005] The setting is then mounted on the frame via its lower end which is introduced inside a blind housing of the frame which is assigned to it. It will be noted here that the frame can be equipped with a setting or several settings respectively carrying identical or differentiated decorative elements. Conventionally, according to a case of permanent mounting of the setting on the frame, the setting is mounted by close fitting inside the blind housing of the frame which receives it and / or is sealed inside said housing at its bottom.

[0006] In the field of jewelry, there has emerged a customer appetite for allow a replacement of a decorative element installed on a setting with another decorative element different from the previous one. This presents a difficulty to overcome in order to allow any individual to easily interchange differentiated decorative elements on the setting, in order to quickly modify the external appearance of the jewelry item.

[0007] For this purpose, it has been proposed in particular to hold the kitten on the frame in a reversible manner by magnetism - or in other words by magnetization - via a pair of elements for fixing the kitten on the frame which cooperate with each other by magnetism. One of the fixing elements is fixed to the base of the kitten oriented towards the bottom of a housing of the frame which receives it, and the bottom of the housing is equipped with the other fixing element. Such fixing elements are potentially constituted, either for each of them by a magnet, or for one of the fixing elements by a magnet cooperating with a ferromagnetic plate constituting the other fixing element.

[0008] However, in this context, there arises an antagonism between obtaining a firm hold of the setting on the frame and, conversely, an ease for the user of the jewelry item to be able to easily remove the setting from the frame. To overcome this antagonism, various solutions have been proposed in order to facilitate the gripping of the setting by the user and to exert a gesture opposing the magnetic attraction holding the setting inside the housing of the frame which receives it.

[0009] For example, according to document US3509734A (HENRY B LEDERER), the setting is provided with lateral ears for gripping the setting by the user. The ears are located on the frame symmetrically on either side of the housing receiving the setting. The user can thus grasp the setting from the outside of the frame via the ears for its removal by pulling it out of the frame.

[0010] For example, according to document FR2751517 (BOIVIN JOSETTE), the top of the setting emerges from the housing of the frame which receives it, and has a peripheral groove for gripping the setting by the user. The user can thus grasp the setting from outside the frame via the groove for removing it from the frame.

[0011] For example, according to another approach proposed by document EP2625980 (GASSAN DIAMONDS), the setting is installed on the mount by being threaded onto a collar of the mount and being fixed to the collar via a bayonet device. By rotating the setting relative to the collar, the user can easily install the setting on and / or remove it from the mount.

[0012] For customers of jewelry items, it is appropriate to optimize the enhancement of the decorative element installed on a setting and this without hindering its installation on and / or its removal from the setting which are easy and quick to carry out. by customers. In addition, it would be appropriate to be able to offer customers the possibility of mounting several decorative elements on the same frame, thus best enhancing the frame itself. Presentation of the invention

[0013] In this context, the invention relates to a piece of jewelry, such as, for example, a ring, a band, an earring, a fibula or any other adornment and / or set such as a brooch or other ornaments with a mount on which at least one setting bearing a decorative element is removably mounted. The setting is held on the mount via magnetically cooperating fixing elements, in order to allow an individual to easily interchange settings bearing different decorative elements on the same mount.

[0014] Based on the previously stated observation relating to the approach taken, an aim of the invention is to propose such an article of jewelry which best meets customer satisfaction, both with regard to the enhancement of a decorative element installed on a setting fixed to a setting by magnetization, and with regard to the ease for an individual to mount the decorative element on and / or remove it from the setting.

[0015] It is more specifically aimed by the invention to overcome at least the following difficulties: -) propose such an ergonomic jewelry item, based on a compromise reconciling a firm and reliable magnetic hold of the setting on the frame, preventing its unexpected removal - such as for example under the effect of a shock - and conversely its removal from the frame, which is easy and quick to carry out by any individual, such as a customer of the jewelry item; -) limit the size of the setting in relation to the frame and in particular its transverse extension - the transverse concept being understood as perpendicular to the direction of assembly between the setting and the frame - and limit the size of the means for magnetically holding the setting on the frame; -) design such aforementioned limitations without altering the firm and reliable holding of the setting on the frame, and without hindering or even nevertheless optimizing the potential for highlighting the decorative element, and / or even by allowing the fixing on the frame - close to each other - of a plurality of setting stones individually carrying a decorative element; -) allow mounting of the decorative element on a setting which is either of the type by sealing and / or by crimping the decorative element inside a blind cavity of the setting, or alternatively which can be of the type of setting equipped with a raised claw structure for holding the decorative element overhanging the setting; and / or -) offer such a piece of jewelry at a lower cost in the context of notoriously tough economic competition in the field of jewelry, particularly costume jewelry. Indeed, an additional cost for the jewelry item can make a potential solution prohibitive due to the costs involved, which requires additional research efforts.

[0016] According to an explanatory approach to the inventive process which has been carried out, a piece of jewelry is proposed according to which at least one setting bearing a decorative element is installed on a mount. The mount comprises a housing for installation by sliding fitting of the setting onto the mount, following an assembly direction which is centered relative to the setting and to the housing of the mount which receives it.

[0017] The kitten is more specifically held magnetically in position on the mount, via a pair of fixing elements cooperating by magnetization with which they are respectively equipped - such as commonly a magnet cooperating with a ferromagnetic plate or two magnets cooperating with each other - the fixing elements being in one piece and centered along the assembly direction.

[0018] In this context, the quality of the maintenance of the kitten on the frame deserves to be improved, to prevent any unexpected escape of the kitten from the frame. However, the optimized quality of a firm maintenance of the kitten on the frame conversely prevents its easy removal by an individual. Furthermore, it is appropriate that the kitten carrying the decorative element does not affect the enhancement of the decorative element and / or the frame itself, which is sought to be optimized.

[0019] Based on this observation, it is proposed to resolve the problem linked to the antagonism between obtaining a firm hold of the setting on the frame and the ease of its removal by an individual, taking into account in this research the desirable achievement of an optimized enhancement of the decorative element and / or the jewel.

[0020] To do this, the setting bearing the decorative element is held on the frame using permanent magnets developing a magnetic field of a sufficiently high power to prevent any risk of unexpected extraction of the setting from the frame, such as for example which could be caused by a shock sustained by the item of jewelry and / or by defective cooperation between the magnets respectively constituting the fixing elements. Means are also implemented for extracting the setting from the frame allowing an individual to easily oppose the cooperation between the magnets despite the power of the magnetic field which they develop.

[0021] To avoid, when removing the kitten from the mount, a risk of the powerful magnets with which they are respectively equipped becoming detached, the magnets are firmly sealed respectively to the base of the kitten and to a bottom wall of the housing which receives it, in particular via a glue with a high adhesion coefficient such as, for example, an epoxy resin.

[0022] To promote the desired optimal highlighting of the decorative element, the choice is made to house the setting entirely inside the housing of the frame which receives it. The setting and the housing are of complementary cylindrical conformations and are centered on the assembly direction in the mounting position of the setting on the frame. The decorative element emerges from the housing inside which the setting is installed, raising the frame and preferably covering as much as possible or even completely the upper end of the setting.

[0023] The setting is thus almost invisible by being masked by the decorative element emerging from the frame overhanging the setting, which promotes the highlighting of the decorative element. However, the absence of emergence of the setting from the frame prevents it from being grasped by an individual for its removal, otherwise to inappropriately use the decorative element at the risk of damaging it. To remove the setting from the frame, access to the setting is provided towards its bottom oriented towards the bottom wall of the housing of the frame which receives it. Such access allows an individual to remove the setting from the frame, by forcefully pressing against the bottom of the setting causing its extraction from the frame.

[0024] For this purpose, the superposition of the magnets, which are each monobloc and applied against each other in a centering position on the assembly direction, is partially provided by differentiation of the respective transverse extensions of the magnets. The transverse extension of a first magnet equipping the bottom of the setting is greater than the transverse extension of a second magnet equipping the bottom wall providing the receiving housing of the setting inside the mount. An empty transverse space is thus provided inside the housing between the wall of the mount which delimits it and the second magnet. This transverse space provides access to the bottom of the setting from inside the housing receiving the setting.

[0025] Access to the interior of the housing from the exterior of the setting is provided by at least one channel passing through the bottom wall of the housing. The channel provides a guide passage for a removable accessory of the jewelry item, via which an individual can forcibly press against the first magnet - and therefore against the setting at its bottom - to cause the setting to be pushed out of the setting.

[0026] Said accessory is advantageously a single piece comprising a member for gripping by an individual which is extended by a rod or any other similar member of thin and elongated conformation. The rod forms a forced support member against the setting by being guided inside said channel by an individual handling the accessory, to finally cause the setting to be pushed out of the frame under the effect of the forced support exerted by the rod against the first magnet equipping the kitten, which is caused by the individual exerting via the accessory the pressing force of the rod applied against the first magnet.

[0027] The ergonomics of the accessory can be adapted according to the conformation of the frame and / or according to the ease of handling of the accessory by an individual to exert the forced support, and / or according to the position(s) of the channel(s) for introducing the rod against the first magnet and therefore against the setting. For example, concerning various potential conformations of the frame - such as for example a ring or a pin - access to the channel can be more or less difficult to obtain. In this case, the conformation of the distal end of the support member can be adapted, for example by being tapered and / or more or less bent to facilitate the introduction of the distal end of the rod inside the channel or selectively, if necessary, one of the channels.

[0028] The notions proximal and distal applied to the accessory of the jewelry item are notions relating to the manipulation of the accessory by the individual, via the gripping member considered provided at the proximal end of the accessory. The gripping member of the accessory is advantageously formed from a rigid plate sized to allow it to be held between two fingers of an individual, such as a plate preferably shaped as a disc. The rod is integrated into the plate via its edge, extending as an extension of the edge of the plate perpendicular to its thickness.

[0029] The kitten and the wall of the mount delimiting the housing which receives it being preferably of cylindrical conformations, the first magnet and the second magnet are each shaped into a disc, it being recalled if necessary that in this case the respective diameters of the first magnet and the second magnet are differentiated as previously explained.

[0030] The decorative element is installed inside a blind cavity that the upper end face of the setting has. The decorative element is in particular fixed inside the cavity preferably by gluing, without however excluding crimping or crimping reinforced by gluing. The decorative element emerges from the cavity by raising the setting, masking the setting which is entirely housed inside the housing that the mount has for this purpose.

[0031] The transverse extension of the decorative element emerging from the frame may be more or less substantial, for example being limited to the periphery of the cavity that the setting includes or the upper opening of the housing that receives it, or even by extending more or less in adjusted coverage of the frame. This makes it possible to promote the highlighting of the decorative element that appears alone on the surface of the frame, while avoiding an individual wishing to remove the setting from the frame, having to exert traction on the decorative element and consequently inducing a risk of its alteration or even degradation.

[0032] Extracting the setting by pushing it out of the mount via the bottom also provides the opportunity to mount the decorative element on the setting via a claw structure that enhances the decorative element. It is therefore necessary to point out here that such a claw structure is considered fragile and cannot be used to extract the setting from the mount without risking its deterioration, particularly given the power of the magnets firmly holding the setting inside the housing that houses it entirely.

[0033] In summary from the foregoing, the invention relates to an article of jewelry comprising a setting bearing a decorative element and a mount provided with a housing for receiving the setting by sliding interlocking.

[0034] The kitten is removably mounted by magnetism in a one-way assembly direction defining a direction of mounting of the kitten inside the mount and a direction of removal of the kitten from the mount which are oriented in the assembly direction in opposition to each other.

[0035] The kitten comprises a base, the outer face of which is equipped with a first fixing element cooperating by magnetization with a second fixing element installed at the base of the housing that the mount comprises. The first fixing element and the second fixing element are coaxial, being centered relative to the kitten and to the housing that receives it in the assembly direction and being superimposed in direct contact with each other in the mounting position of the kitten on the mount.

[0036] In this context, the jewelry item of the invention is mainly recognizable: in that perpendicular to the assembly direction, the cross-section of the first fixing element is greater than the cross-section of the second fixing element. An empty transverse space is thus provided inside the housing around the second fixing element, between the wall delimiting the housing and the second fixing element, and in that at least one channel is provided through a bottom wall of the housing opening onto said transverse space. The channel forms a guide corridor for a removable accessory of the jewelry item, which is an accessory for pushing the setting out of the housing by forced support of the pushing accessory against the first fixing element.

[0037] It is understood that the forced support of the accessory against the first fixing element is exerted by an individual handling it by applying via the accessory a force against the first fixing element in said direction of withdrawal.

[0038] Other specific characteristics of the jewelry item - not restrictive or limiting with regard to other characteristics that it may have - are as follows.

[0039] The kitten and the housing which receives it are of complementary cylindrical conformations and are centered on the assembly direction in the mounting position of the kitten on the frame. The kitten is entirely inserted inside the housing which the frame comprises and the decorative element is arranged outside the housing raising the kitten and the frame.

[0040] The first fixing element is formed from a first single-piece magnet and the second fixing element is formed from a second single-piece magnet.

[0041] The discharge accessory comprises at its proximal end a gripping member extended by a support member via its distal end against the first fixing element. The support member is of elongated and thin conformation in accordance with a cross-section less than or at most equal to the cross-section of the channel.

[0042] The accessory is a single-piece, the gripping member of the accessory being shaped as a plate whose edge is extended by a rod constituting the support member. It is understood that the rod extends longitudinally in a direction perpendicular to the extension of the plate along its thickness.

[0043] The bottom wall of the housing comprises a plurality of said channels which open individually at a distance from each other onto said transverse space.

[0044] The first fixing element and the second fixing element are respectively fixed on the kitten and at the bottom of the housing by sealing, via a resin with a high adhesion coefficient.

[0045] The first fixing element and the second fixing element are each advantageously shaped as a disc, or according to a more complex and / or less ergonomic variant may have a polygonal cross-section.

[0046] The decorative element is in particular fixed by crimping and / or by gluing inside a cavity which the setting comprises, emerging from the cavity by raising the setting which it masks.

[0047] Selectively according to alternative embodiments: -) either the decorative element extends at most to the periphery of the kitten, -) or the decorative element extends beyond the setting, forming a decorative cover for the frame adjusted to its conformation. -) or the decorative element is fixed to the setting via a claw structure for mounting the decorative element, the claw structure being mounted on the setting overhanging the setting.

[Fig. 12] is a partial sectional view of the setting provided with a decorative element, which is consistent with the setting provided with centering members illustrated in Figures 10 and 11. In [Fig. 12], the setting is installed on a storage base for the setting provided with the decorative element, such as a base of a jewelry display or the base of a storage box for one or more settings respectively provided with identical and / or differentiated decorative elements. [Fig. 13] is a sectional view of a piece of jewelry according to a second embodiment of the invention, comprising a setting shaped like a bracelet according to the example illustrated. A setting conforming to the setting illustrated in Figures 11 and 12 is housed inside the setting. In [Fig. 13], the setting carries a decorative element partially covering the setting and extending on either side of the setting. Detailed description of the invention

[0049] The figures and their detailed, non-limiting descriptions set out the invention in particular ways which are not restrictive as to the scope of the invention. The figures and their detailed descriptions of an exemplary embodiment of the invention may serve to better define it, if necessary in relation to the general description which has just been given.

[0050] Furthermore, to avoid overloading the figures and thus facilitate their reading, the reference numbers assigned to the terms and / or concepts used to describe the invention and indicated in any one of the figures are potentially repeated in the description of any other figure without implying their presence in all of the figures.

[0051] In [Fig.l], a piece of jewelry 1 comprises a setting 2 on which is mounted at least one setting 3 carrying a decorative element 4. The setting 2 shown by way of example is shaped into a bracelet and the decorative elements 4 respectively installed on the settings 3 may be similar and / or differentiated at least two by two. As illustrated, the settings 3 are in plurality by being arranged juxtaposed on the setting 2 close to each other. Such proximity of the settings 3 individually carrying the decorative elements 4 makes it possible to optimize the aesthetic effect obtained from the piece of jewelry 1.

[0052] Thus, for non-restrictive information: -) At least one of the decorative elements 4 is for example formed from a gem, such as a fine stone or a precious stone. For example again, at least one of the decorative elements 4 may be made from a resin potentially provided with inlays or from a potentially engraved metallic material. For example again, the decorative element 4 can be arranged as a decorative cover of the frame 2 as illustrated in [Fig. 13]. -) The setting 2 is for example arranged as a ring, an open bracelet - as illustrated in [Fig.l] - or closed on itself - as illustrated in [Fig. 13] - as a necklace or pendant, as an earring, as a pin or brooch, as a fibula or a ferret, or as any other adornment.

[0053] The kittens 3 are installed individually on the mount 2, each following a unidirectional assembly direction DI. The assembly direction DI defines for each of the kittens 3 a globally unidirectional assembly direction SI of the decorative element 4 of which the kittens 3 are carriers, and of the kittens 3 on the mount 2 following the assembly direction SL. Following the assembly direction D1, the assembly direction SI is opposite to a globally unidirectional removal direction S2 of the kitten 3 from the mount 2.

[0054] In Figures 2 and 3, the jewelry item 1 further comprises a removable one-piece accessory 5 usable by an individual, to individually extract the setting stones 3 at least partially from the setting 2. Such extraction of the setting stone 3 via the accessory 5 allows the individual to extract it at least partially from the setting 2 for its removal and replacement by another similar setting stone 3 which carries another decorative element 4 different from - or similar to - that installed on the setting stone 3 previously removed from the setting 2.

[0055] The removable accessory 5 comprises a gripping member 5a for an individual and a support member 5b individually against one or more of the kittens 3, to cause them to be withdrawn from the frame 2 in the unidirectional withdrawal direction S2. The support of the accessory 5 against the kittens 3 is exerted by the individual via the distal end 6 of the support member 5b, as described later in relation to FIGS. 6 to 8.

[0056] The gripping member 5a is advantageously arranged in a plate 7a - preferably shaped as a disc as more particularly visible in [Fig.2] - to allow the individual to easily grasp and manipulate the accessory 5 at its proximal end between two of his fingers of one hand. The support member 5b is shaped in a thin and elongated rod 7b which is integrated via its proximal end into the edge of the plate 7a defining its thickness. The rod 7b extends in extension of the edge of the plate 7a - perpendicular to its extension in thickness - as more particularly visible in [Fig.3]. Such a rod 7b is thin and tapered, the distal end 6 of which can nevertheless be bent according to the ease of access and introduction of the distal end 6 of the rod 7b inside a channel 13 which the frame 2 comprises.

[0057] In Figures 4 to 9, the removable mounting structure of a decorative element 4 on any mount 2 - such as that illustrated for example in [Fig.l] - essentially comprises the setting 3 carrying the decorative element 4 and a housing 8 arranged inside a bottom wall 8a which the mount 2 comprises. The setting 3 is removably mounted by magnetism inside the housing 8, via fixing elements 9a, 9b cooperating by magnetization with which they are respectively equipped.

[0058] The fixing elements 9a, 9b are more specifically made up of single-piece magnets 10a, 10b, a first magnet 10a of which is fixed to the outer face of a bottom 3a of the setting 3 and a second magnet 10b of which is fixed to the bottom of the housing 8 that the mount 2 comprises. The magnets 10a, 10b are of an optimized power to firmly hold the setting 3 on the mount 2. To avoid the magnets 10a, 10b becoming detached from the setting 3 and / or from the bottom of the housing 8 despite their optimized magnetic power, the magnets 10a, 10b are respectively fixed by sealing to the setting 3 to the outer face of its bottom 3a and to the bottom of the housing 8, via a resin 11 with a high coefficient of adhesion such as an epoxy resin 11 for example.

[0059] It is obviously understood that the power of the magnets 10a, 10b is optimized while nevertheless being limited to a resistance threshold of their cooperation with each other. Said resistance threshold is determined on the one hand to allow forced extraction of the setting 3 from the frame 2 via the accessory 5 manipulated by an individual, and on the other hand to prohibit detachment of at least one of the magnets 10a, 10b from the setting and / or from the frame 2, in particular during the operation of forced extraction of the setting 3 from the frame 2 via the accessory 5 as illustrated in [Fig.7].

[0060] The kitten 3 and the wall of the mount 2 delimiting the housing 8 are of complementary cylindrical conformations, the magnets 10a, 10b each being shaped like a disc. In the mounting position of the kitten 3 inside the housing 8 as illustrated in FIGS. 5 and 6, the kitten 3, the housing 8 and the magnets 10a, 10b with which they are respectively equipped are coaxial while being centered on the assembly direction DI.

[0061] Such arrangements make it possible to provide a space El around the first magnet 10a, which is used to easily remove the setting 3 from the mount 2 by an individual, as described later in relation to FIGS. 6 to 9.

[0062] In the mounting position of the kitten 3 on the frame 2, the kitten 3 is entirely housed inside the housing 8 that the frame 2 comprises as illustrated in FIGS. 5 and 6. Thus, only the decorative element 4 emerges from the frame 2, raising the kitten 3 to promote its enhancement. At the end of the travel of the kitten 3 inside the housing 8, the magnets 10a, 10b are applied against each other so that they cooperate, preventing spontaneous withdrawal of the kitten 3 from the frame 2, including without voluntary intervention by an individual.

[0063] More specifically as illustrated successively in [Fig.4] and [Fig.5] and according to the embodiment shown, the installation of the decorative element 4 on the setting 3 is carried out - preferably in the workshop - by introduction following the assembly direction SI of the decorative element 4 inside a cavity 12 which the setting 3 comprises. The decorative element 4 is sealed inside the cavity 12 for its firm holding inside the setting 3, potentially by crimping or preferably by gluing as illustrated.

[0064] According to the example illustrated in [Fig.l] and figures 4 to 9, the decorative element 4 glued inside the cavity 12 of the setting 3 may comprise a shoulder 4a covering the peripheral wall of the setting 3. The setting 3 is thus completely masked by the decorative element 4, which promotes an enhancement of the decorative element 4, in the absence of an overflow of the setting 3 at the periphery of the decorative element 4 and / or an overflow of the decorative element 4 onto the mount 2.

[0065] The kitten 3 is fully introduced inside the housing 8 that the frame 2 comprises, by sliding or slightly floating sliding, a tolerance play being able to be provided in them to facilitate the introduction of the kitten 3 inside the housing 8 and / or conversely its removal from the frame 2 by an individual using the accessory 5, as described below in relation to figures 6 to 9.

[0066] In [Fig.l] and more visible in Figures 4 to 9, as well as in [Fig. 13] and more visible in Figures 10 to 12, the cross sections respectively of the first magnet 10a and of the second coaxial magnet 10b are of different dimensions. More precisely, the cross section of the first magnet 10a is greater than the cross section of the second magnet 10b. The notion of transverse is understood perpendicular to the assembly direction DI.

[0067] More particularly visible in Figures 5 and 6 and in Figures 10 and 11, an empty space El is thus provided around the second magnet 10b installed inside the housing 8. Said space El on the one hand extends transversely between the periphery of the second magnet 10b and the wall of the mount 2 delimiting the housing 8, and on the other hand extends between the bottom of the housing 8 and the first magnet 10a. At least one channel 13 is provided through the bottom wall 8a of the housing 8, opening on the one hand towards the outside of the mount 2 and on the other hand onto said space EL

[0068] The cross-section of the channel(s) 13 is greater than the cross-section of the rod 7b constituting the support member 5b that the accessory 5 comprises. The channel(s) 13 allow an individual to introduce IT1 the rod 7b inside said space El and to apply it - via its distal end 6 - against the first magnet 10a as illustrated in [Fig.6]. Then as illustrated in [Fig.7], the individual can thus exert via the rod 7b a forced support PA1 against the setting 3 - via the first magnet 10a - to cause a pushing back of the setting 3 which emerges from the housing 8 in the direction of withdrawal S2 of the setting 3 from the mount 2.

[0069] As illustrated successively in Figures 7 to 9, the pushing back of the setting 3 out of the housing 8 exerted by the individual via the accessory 5 is preferably partial, to avoid an unexpected escape of the setting 3 out of the frame 2 which could lead to its loss. As illustrated in Figures 7 and 8, the setting 3 nevertheless emerges out of the housing 8. The individual can thus grasp PI laterally with one hand between his fingers the emerging part of the setting 3 to extract it completely from the frame 2, and remove RI the accessory 5 out of the frame 2 via his other hand which manipulates it, as illustrated successively in Figures 8 and 9.

[0070] In Figures 10 to 13, the setting 3 comprises centering members 14 for the setting 3 inside the bottom wall 8a of the housing 8 that the mount 2 comprises. The centering members 14 are transversely distant from each other while being equidistantly distributed on either side of the assembly direction DI. The centering members 14 are shaped as pins that extend along the direction DI - the following term being understood parallel to the direction DI - in extension of the external face of the bottom 3a of the setting 3.

[0071] The mount 2 comprises, through the bottom wall 8a of the housing 8, at least one set of two channels 13 which are transversely distant from each other while being equidistantly distributed on either side of the assembly direction D1, in correlation with the respective transversely distant positions of the centering members 14. The centering members 14 combine several functions.

[0072] As illustrated in [Fig.l 1] according to a first function of the centering members 14 in the position of fitting the kitten 3 inside the housing 8 that the mount 2 comprises, the centering members 14 are respectively introduced inside the channels 13 that the bottom 8a of the housing 8 comprises. This makes it possible to rigorously position the kitten 3 inside the housing 8, and thus to authorize a sliding fitting play between the kitten 3 and the housing 8 to promote freedom of sliding of the kitten 3 during its introduction inside and / or conversely its removal from the housing 8, avoiding a risk of blocking the kitten 3 against the wall of the housing 8.

[0073] As illustrated in [Fig. 12] according to a second function of the centering members 14, the centering members 14 can be used for storage by fitting the setting 3 onto a base 15 - preferably ferromagnetic - comprising recesses 13a. Such recesses 13a are of shapes complementary to those of the centering members 14 and are transversely distant from each other in correlation with the transversely distant relative positions of the centering members 14. By way of examples, the base 15 advantageously equips a jewelry display and / or a storage box with one or more setting 3 respectively provided with decorative elements 4 that are identical and / or differentiated from each other.

[0074] According to a third function of the centering members 14, these constitute members for supporting the accessory 5 against the setting 3 during its extraction from the housing 8 included in the frame 2, as previously explained in relation to FIGS. 6 to 8. This makes it possible to avoid untimely degradation of the first magnet 10a equipping the bottom 3a of the setting 3, as a result of the forced support exerted by an individual via the accessory 5 against the setting 3 during its extraction from the housing 8 included in the frame 2.

[0075] As illustrated for example in [Fig. 13] according to a fourth function of the centering members 14, these can be used to stabilize the positioning and the holding by magnetization of a decorative element 4b extending significantly by closely covering - at least in part - the external surface of the frame 2. The decorative element 4b is for example made of a material different or similar to that of the frame 2, and / or can be decorated on its surface visible from the outside of the frame 2, such as by engraving or by solid or patterned coloring.

[0076] According to this other aspect of highlighting the decorative element 4b, the shape of the decorative element 4b is complementary to that of the surface of the setting 2 which it covers. The decorative element 4b thus forms a decorative cover which extends more or less significantly and equally on either side of a single setting 3 which - as previously described - is of small size and is installed on and / or removed from the setting 2 via the accessory 5 of the jewelry item.

[0077] The tips of the ends 4c of the decorative element 4b are flush with the surface of the mount 2 against which the decorative element 4b is held applied by the setting 3. As a result of the decorative element 4b being held firmly against the mount 2 via the setting 3, such flushing prevents a potential case of the decorative element 4b catching via its ends 4b, which could lead to a risk of it being removed from the mount 2. However, in such a case, the centering members 14 equipping the setting 3 prevent any floating relative to the vertical direction DI of extension of the setting 3, and consequently a removal of the decorative element 4b from the mount 2.

[0078] It will be noted in conclusion, without limitation - and in isolation or in combination at least two by two - that from the provisions relating to the invention: -) the ergonomics of the jewelry item 1, which combines on the one hand a firm and reliable hold of the setting 3 inside the setting 2 - via powerful magnets 10a, 10b which are firmly sealed respectively to the bottom 3a of the setting 3 and to the bottom of the housing 8 of the setting 2 which receives it, effectively preventing an unexpected removal of the setting 3 from the setting 2 - and on the other hand without however preventing an easy and effective removal of the setting 3 from the setting 2 which is carried out voluntarily by an individual from the external face of the bottom of the housing 8 of the setting 2 housing the chaton 3, via the removable accessory 5 for pushing the chaton 3 out of the setting 2. -) the ergonomics of the jewelry item 1 is further enhanced by the presence of the annular space El provided around the second magnet 10b. Such an annular space El makes it possible to provide one or more channels 13 through the bottom wall 8a of the setting 2 to facilitate the identification by an individual handling the accessory 5 of any channel 13 for introducing the accessory 5 inside the housing 8, and / or to assist the individual in the gesture guiding the accessory 5 inside a channel 13 to effectively and easily push the chaton 3 out of the setting 2 despite the single-piece and coaxial nature of the magnets 10a, 10b equipping the chaton 3 and the setting 2 respectively. -) The small size of the setting 3 embedded inside the mount 2, and its small transverse extension from the use of only two powerful monobloc magnets 10a, 10b cooperating with each other, which are shaped as coaxial discs of differentiated diameters centered on the direction Dl. This makes it possible to install on the same mount 2 close to each other several decorative elements 4 juxtaposed favoring the enhancement of the jewelry item 1. The monobloc discs constituting the magnets 10a, 10b are respectively firmly sealed at the bottom of the setting 3 and at the bottom of the housing 8 of the mount 2 which receives it, by transversely providing between them the annular space El surrounding the second magnets 10b which is of a sufficient transverse dimension to allow the introduction of the thin rod 7b of the accessory 5 to extract the setting 3 from the mount 2.

[0079] -) The enhancement of the decorative element 4 or 4b is optimized by the introduction of the setting 3 entirely inside the housing 8 of the mount 2 and the only emergence outside the mount 2 of the decorative element 4 or 4b, which preferably masks at least the setting 3. Such highlighting of the decorative element 4 is provided without having to equip the decorative element 4 and / or the setting 3 with a specific unsightly member which would be visible from the outside of the mount 2 and via which the setting 3 would be removed from the mount 2. -) The setting 3 can be masked by the decorative element 4 or 4b, either without overflowing on either side of the setting 3, or by overflowing from the setting, forming a decorative cover for the setting 2. The decorative character of the decorative element 4 or 4b - and therefore of the jewelry item 1 - is optimized. -) The enhancement of the mount 2 itself can be optimized by placing a decorative element 4b covering it by being firmly fixed to the mount 2 via a single setting 3, nevertheless of small size, which can be completely embedded inside the mount 2, and which can be stabilized in position on the mount 2 via the centering members 14. -) extraction of the kitten 3 from the mount 2 by pushing back via the accessory 5 guided inside a channel 13, provides the possibility of mounting the decorative element 4 on the setting 3 either by sealing and / or by crimping inside a cavity 12 provided inside the setting 3, or via a claw structure installed as a raised part on the setting 3 for holding the decorative element 4, and this without risking damaging the claws as a result of their being seized inopportunely by an individual to remove the setting 3 from the mount 2.
