DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(10) FIG. 1 presents a bracelet comprising a rigid structure 2 formed in a cut strip of metal plate that is curved to form a loop with an opening through which the wrist can pass.

(11) Other materials can be used to make the rigid structure, for example wood or a rigid polymer.

(12) The openings 14 may be made by cutting, grinding or by a means other than continuous edge to edge attachment of parts so as to leave open spaces between the parts. For example, parts can be welded to each other so as to obtain the rigid structure with openings according to the invention.

(13) A leather lining 4 in contact with the inside of the metal structure 2 on its back face, forms a rectangle for which the longs sides 6 are adjusted on the edges of the metal plate, and the short sides 8 are slightly set back from this metal plate.

(14) The lining 4 forms a plate that can be elastically curved, fixed to the inside of the structure by two studs 10 each located on the centre line of the strip close to one end of this strip, and two lateral tabs 12 each arranged in the middle of a long side of this structure.

(15) Alternatively, as illustrated on FIG. 11, the bracelet may comprise two lateral tabs called end tabs located on the back face of the structure, close to or at each end 8 of the metal plate strip, and lateral tabs on the sides 6 of this strip forming supports on the edges of the lining. The lateral end tabs 15 may advantageously include a claw structure so that the lining is kept in compression throughout its thickness under the lining.

(16) An example lining compatible with this embodiment is illustrated in FIG. 12. The decorative lining 4a comprises means 16a of cooperation with the reversible attachment means 15 of the structure. On this example, the cooperation means consist of notches 16a. The lateral tabs 15 can engage in these notches 16a so as to transversely block the lining relative to the rigid structure, and apply a pressure that tends to bend it and push it towards the metallic structure, which forces it into contact with the back face to provide the required aesthetic effect. To achieve this, the distance D2 between the ends of the notches 16a is slightly more than the corresponding distance between the lateral tabs 15 along the back face of the rigid structure 2.

(17) More generally, the attachment means (the studs 10 and the lateral tabs 12, or the lateral end tabs 15 and the lateral tabs 12) squeeze the lining along the lateral directions of the plate: longitudinal along the centre-line passing through the studs; and transverse along the centre line connecting the lateral tabs located on the edges of the rigid structure. They apply a stress on the lining keeping it in contact in the structure without play and therefore without wear, and generate a pressure that tends to bend it and push it towards the metal structure, which forces it into contact on the back face giving the required aesthetic effect.

(18) The thickness of the metal plate of the structure 2 is about 1 to 2 mm, the thickness of the leather lining 4 may be up to about 4 mm. A slightly supply leather is chosen with an elasticity and shape memory such that it can return to its form after bending. If necessary, a stack of leather pieces can be assembled together making the lining semi-rigid, for example with a flexible central core about 1/10 mm thick.

(19) FIG. 2 shows the metal plate of structure 2 cut out from a metal strip such as a steel or a brass, comprising aligned openings 14 over its entire surface area, with geometric contours that can occupy more than half of the total surface area. The result obtained is a simple clean pattern, highlighting the motifs forming a sort of metal lace. Other cut types can be used, for example to form writing.

(20) Cuts in the structure 2 can also be combined with stamping or engraving on the metal plate surface, to form other decorative effects such as writing. The surface of the structure 2 may be polished, satin or mat, comprising a metal or a coating with good mechanical strength and resistance to oxidation and chemicals so that it retains its appearance without wear and without deterioration. In particular, a gold, silver, ruthenium, palladium or rhodium coating can be applied.

(21) FIG. 3 shows a leather lining 4, forming an approximately rectangular strip with rounded corners, comprising a hole 16 near each end along the main axis of this strip. As a variant, the bracelet may have a different number of studs 10, for example one or three. It does not necessarily have any studs, the lining 4 may be retained by lateral tabs 12 and/or 15 alone, the lining being forced into contact with the inside of the curved structure 2 by its elastic effect that tends to straighten it.

(22) FIG. 4 shows the stud 10 with an approximately spherical head 20 fixed to the metal plate of the structure 2 by a short rod 22 welded vertically onto this metal plate. For a thin lining 4, the spherical head 20 alone can be fixed directly to the metal plate of the structure 2, without a rod. The diameter of the hole 16 in the lining 4 is slightly smaller than the diameter of the head 20.

(23) The lining 4 is assembled by placing the hole 16 above the head 20 as shown in position A, and this lining is then lowered by pressing it onto the structure 2 so as to strain the material around the hole and enlarge it, to come into position B bearing on the metal plate. The spherical shape of the head 20 facilitates its insertion into the hole 16, and forms a curved surface that is not aggressive to the skin of the wrist.

(24) The height of the head 20 can be adjusted as a function of the lining 4 to obtain permanent vertical pressure on the lining by the head, leaving it firmly in contact with the metal plate of the structure 2. FIG. 5 shows the lateral tab 12 of the structure 2 that forms a 90? fold, the end 18 of which terminates slightly below the top level of the lining 4 so that it does not project above it and so that it will not irritate the skin of the wrist and will not get caught on anything.

(25) FIGS. 6A, 6B and 6C present the assembly method for the bracelet.

(26) FIG. 6A shows firstly shaping of the lining 4 that is rolled to form a bend with a diameter slightly less than the diameter of the structure 2 below it, shown in FIG. 6B. The lining 4 is then lowered vertically by axial sliding along the direction of arrow 30, sliding it into the structure 2 to stop in contact with the lower lateral tab located under this structure. At this moment, the upper edge of the lining 4 also goes past the upper lateral tab 12. The lining 4 is then adjusted between the two lateral tabs 12 that form lateral packing in the two directions.

(27) FIG. 6C then shows a pressure F applied to the inside of the lining 4 at each stud 10, to engage the studs 20 in the holes in this lining. In making the distance D2 between the two holes 16 in the lining 4 slightly larger than the clear distance D1 between the two heads 20 along the curvature of the structure, there will be a given lateral pressure between this lining and the metal plate retaining it in place with no play.

(28) In general, the invention advantageously provides that the lateral distance D1 between two attachment means (the studs 10 or the lateral end tabs 15) along the contour of the back face of the structure 2 is less than the corresponding distance D2 on the lining 4, that is to say the distance D2, before fixing, between the points of the lining 4 where the attaching means will be engaged when the lining 4 is fixed and pressed against the back face of the structure: distance D2 between two holes 16 (FIG. 3), or distance D2 between two lateral end tabs 15 (FIG. 11).

(29) This in order to apply lateral pressure to it and to force it into contact with the back face of the structure by these attachment means.

(30) Furthermore, the slightly elastic shape memory of the lining 4 tends to maintain its separation inside the structure 2, which reinforces the pressure forcing it into contact inside this structure. The fast and simple mounting of the lining 4 without tools, assures efficient positioning that is maintained in the long term.

(31) The result obtained is a bracelet that has the bright and luminous appearance of the metal structure 2 conferring the general shape of the jewellery due to its stiffness, decorated with openings 14 through which the leather lining 4 can be seen contributing colour and softness. In particular, a special relief can be chosen to given an appearance of luxury to the jewellery. The combination of two different technologies, metal decorated with cutouts with a metallic lustre and the leather of the lining requiring expertise in two different trades, provides a contrast offering unusual modern aesthetics.

(32) The lining 4 is disassembled simply by pulling on its ends to disengage the heads 20 from the holes 16, and then by squeezing the curved part to disengage the lateral tabs 12 so that it can be extracted by sliding it laterally. It will be noted that no tools are required for disassembly, and that no part is modified or damaged.

(33) Advantageously, there are two different colours on the two faces of the reversible lining 4, so that the same lining can be fitted in one direction or the other so as to obtain two different effects on the same jewellery.

(34) As a variant, a lining 4 can be made with a surface formed by other materials such as natural or synthetic fabric, or a plastic material. If necessary, a stack of materials is made comprising a plate on the inside with some elasticity to control bending and provide a shape memory.

(35) A lining 4 can also be made that projects beyond the sides of the structure at some locations, to be visible and give special aesthetics.

(36) It would be possible to sell linings 4 separately from the rigid structures 2, for example metal structures, so that a large choice of appearances and colours could be available for a lower cost. The lining 4 could also be removed so that the metal structure 2 can be worn by itself, which gives an additional variant presentation. This could advantageously by done in the form of a decoration kit adapted to each rigid structure (a bracelet, pendant, ring, etc.), comprising a plurality of aesthetically different linings each provided with means (holes 16 or notches 16a) of cooperation with reversible attachment means (the studs 10 and/or the lateral tabs 12 and/or 15).

(37) FIG. 7 shows a ring comprising a metal plate structure 2 wound to a small diameter to be adjusted to a finger, in which openings 14 are made to form a d?cor. Rows of small bushings 48 formed by stamping, chemical cutting or engraving of the metal plate finish the d?cor. In particular, etching can be used to economically create precise markings.

(38) The lining 4 forming a strip is inserted into the structure 2 of the ring after having been wound by elastic deformation. Cavities in the inside surface of the structure 2, facing the lining 4 and formed by stamping, chemical cutting or engraving over the entire surface of this lining, form a retention cage applying pressure and locking to assure that it is retained in position.

(39) FIG. 8 show a decorative ring composed of a plain ring 40 designed to be adjusted around a finger, onto which a circular metallic structure 2 is welded comprising rows of openings 14 at its centre, with a circular rim around it forming a continuous bend facing the ring. The lining 4 is composed of a leather disk that is inserted by click fitting into a cage under the metal plate of the structure 2. The plain ring forming part of the decorative ring 40 holds the lining in its housing so that it is forced into contact under the metal plate of the structure 2.

(40) FIGS. 9A and 9B show an open collar necklace comprising a slightly convex metal structure 2 in a croissant shape, of which the tapered ends apply strong pressure to form a circular inner contour forming a passage 46 through which a person's neck will comfortably fit.

(41) The structure 2 comprises rows of openings 14, and rows of small sized bushings 48 between these openings, made by stamping or etching of the metal plate, adding decorative elements. The result is thus a large metal structure 2 that is sufficiently stiff for this type of jewellery made of a single-piece cut metal sheet.

(42) The lining 4 is forced into contact on the back face of the metal plate structure 2 by three studs that force the lining into contact with the metal plate of the structure 2 to retain it in place. FIGS. 10A and 10B show an ear pendant composed of a flat metal plate structure 2 connected to an attachment pin 52 by a chain 50.

(43) The structure 2 comprising rows of openings 14 is provided with tabs 12 at the back around its periphery forming points at which the lining 4 is laterally clamped by click fitting, to hold it in contact with the back face of this structure.
