Description

PORTABLE DECORATIVE ELEMENT COMPRISING A PLATED FIT

UNDER A CUTTED SHEET

The present invention relates to a portable decorative element combining several elements, which may have different aspects and / or be made of different materials.

Modern sheet metal cutting processes make it possible to produce metals, such as steel, brass, copper, aluminum, silver or gold, with varied and fine cuts including particular holes of different shapes, to make jewelry or fashion accessories.

It is known to fix permanently on the inner face of the cut sheet a slightly flexible lining appearing through the openings of this sheet, having a different appearance and colors to achieve a decorative aesthetic effect.

Preferably, for the bottom lining, noble materials, such as natural or synthetic quality fabrics, or leather, are used. Then there is the rigid sheet giving the generole shape of the decorative element, as well as an external appearance that is resistant to abrasion. wear, which can be shiny, satin or matte, and the inner lining forming a softer and warmer material, whose nature, appearance and color contrast with the metal.

In particular, bracelets, broaches, earrings or jumpers may be made comprising a cut metal sheet forming a rigid structure having a particular shape according to its function. Bracelets formed in a rolled sheet metal strip, for example, have an opening allowing the wrist to be adjusted in a neat manner. The lining may receive additional elements to ensure in particular the fastening or carrying function, such as a cardoon or chain passing around the neck for a jumper, or a pin for attaching a pin to a coat.

For jewelry directly in contact with the skin such as bracelets, the softer inner lining gives a more pleasant touch on this skin.

However, a problem that arises with this type of decorative element, is that with an interior liner permanently fixed to the sheet by various means to ensure a good maintenance and a veneer under the sheet, we can not then * Proceed quickly and easily to change this trim.

In addition, detachment of the liner generally requires the use of specialized tools, in particular to remove clamping screws or rivets, and may cause damage to the elements. The disassembly and reassembly operation can be slow and delicate for maintain an impeccable appearance and finish to justify the decorative function.

We can not quickly make variants of the same jewel or decorative element, changing the trim or the decorative sheet, while we seek more and more to customize the fashion accessories to adapt for example to worn clothes, to types of activities planned, or a need for frequent renewal to avoid repeating the same decoration,

The present invention is intended in particular to avoid these drawbacks of the prior art and to allow quick fixing, reversible, without reported attachment part, discrete decoration trim under a rigid structure of a decorative element such as a jewel.

Reversible fastening means a fastener that can be made and defeated manually without tools. permanent, a fixation requiring a thread to be made or defeated (crimping, screwing, gluing, etc.). Thus, a fixing means allowing a manual reversible attachment is qualified in this text as "reversible fastening means",

The present invention proposes for this purpose a portable decorative element comprising a rigid structure having decorative holes, receiving on its rear face, in the use position, a liner forming a visible plate through these bores, which can be bent in a manner elastic, this element being remarkable in that the rear face comprises reversible fixing means adapted to maintain the lining and to apply a clamping of this lining performing its plating against the rear face of the structure.

An advantage of this decorative element is that the fastening means applying a tightening of the liner in lateral directions of the plate, provide a stress on this lining to maintain it without play in the structure and therefore without wear, and generate pressure which tends when it is bent to push the plate outward which gives its veneer on the back side ensuring the desired aesthetic effect. _,

A fastening means which does not fulfill these conditions is for example a slide in which the packing must be slid for its positioning. Indeed, the sliding causes the wear of the lining and does not ensure its clamp against the rear face of the structure since the slide must be higher than the lining to allow its sliding. If the height is not higher, the fixation is not reversible because multiple insertions / outputs "were impossible.

the adjective "lateral" means that the stress is not the edges of the lining. One can then simply and quickly, without tools and without damaging any component, disengage the seal to remove it and replace it for another. This trim can also be used with another metal structure.

The portable decorative element according to the invention may further comprise one or more of the following features, which may be combined with one another.

The rigid structure can be made in a cut sheet having decorative holes.

According to one embodiment, the rear face has lateral lugs forming fastening means, providing support edges of the liner. In this case, advantageously the lateral tabs are formed by a folding of the edge of the sheet of the structure. These side tabs are simple to make,

By "side tabs", it is expected in this text that the tabs are located on the edges of the rigid structure. These doors may be punctual or form a continuous flange constituting, in the latter case, a holding cage. The side tabs may be disposed on the sides or ends of the rigid structure.

According to another alternative or complementary embodiment, the decorative element comprises buttonholes plating the liner on the rear face of the structure. The buttonholes achieve a maintenance of the filling in the different directions.

In this case, advantageously the buttonhole has a substantially spherical button, fixed on the rear face of the structure at a distance ensuring under this button a compression of the lining in its thickness, This compression maintains a plating of the liner on the back side of the structure.

Advantageously, the lateral distance between two fastening means, following the contour of the rear face of the structure, is less than the same distance on the lining so as to ensure its lateral clamping by these fixing means.

In particular, the decorative element may constitute a bracelet comprising a substantially bent sheet metal bung having an opening for the passage of the wrist.

This bracelet advantageously comprises two buttonholes disposed on the rear face of the structure, near each end of the sheet metal strip, and side tabs on the sides of this strip forming supports on the edges of the liner. This effectively maintains the lining in all directions, allowing quick disassembly.

Alternatively, the bracelet may comprise two so-called "end" lateral tabs disposed on the rear face of the structure, near each end or at each end of the rigid structure, and lateral tabs on the sides of this structure forming supports on the edges of the trim

The end side tabs may advantageously comprise a claw structure to ensure under this claw a compression of the lining of its thickness,

In particular, the structure may form a disk having folded edges constituting fixing means.

In particular, the lining may comprise two leather faces. The leather faces are a material ensuring good durability and a pleasant contact with the skin.

Advantageously, the lining has two faces of different colors, designed to be rotated alternately towards the structure. so quickly with the purchase of a single trim, benefit from a decorative element with two different aspects.

The invention also relates to a decorative lining intended to cooperate with the reversible fastening means of a decorative element according to the invention, remarkable in that it comprises means for cooperation with the reversible fastening means.

The invention also relates to a decorative kit of a decorative element according to the invention, comprising a plurality of different previous decorative fittings, each provided with cooperation means with the reversible fastening means.

The invention will be better understood and other features and advantages will emerge more clearly on reading the following description given by way of example, with reference to the appended drawings in which:

- Figure 1 shows a bracelet forming a decorative element according to the invention;

- Figures 2 and 3 respectively show the sheet and the leather trim of this bracelet which are detached;

- Figures 4 and 5 show in cross section, respectively a buttoning of the lining and a lateral lug of this lining;

- Figures 6a, 6b and 6c show the assembly of this bracelet;

- Figures 7 and 8 show two variants of rings according to the invention;

FIGS. 9a and 9b respectively show an overview and a detailed view of a jumper according to the invention;

- Figures 10a and 10b show respectively in front view and side, an ear pendant according to the invention; and

- Figures 1 1 and 12 respectively show an alternative according to the invention of the bracelet of Figure 1 and the leather trim of this bracelet. Figure 1 shows a bracelet having a rigid structure 2 formed in a strip of cut metal sheet, which is bent to form a loop having an opening for the passage of the wrist.

Other materials can be used to make the rigid structure, such as wood, or a rigid polymer.

The holes 1 may be obtained by cutting, molding, or by the non-edge-to-edge binding of solid parts in order to leave empty spaces between them. For example, plates can be welded together to obtain the openwork rigid structure of the blank. invention.

A leather lining 4 plated inside the metal structure 2 on its rear face, substantially forms a rectangle whose long sides 6 are fitted to the edges of the sheet, and the short sides 8 a little set back from the edge of this sheet.

The lining 4 forms a plate which can be elastically bent, fixed inside the structure 2 by two buttonholes 10 each arranged in the axis of the strip, near one end of this strip, and by two legs 12 each disposed in the middle of a large side of this structure.

Alternatively, as illustrated in FIG. 11, the bracelet may comprise two so-called "end" lateral tabs, arranged on the rear face of the structure, near each end or at each end 8 of the sheet metal strip, and tabs lateral sides 6 of this strip forming supports on the edges of the liner. The end lateral tabs 15 may advantageously comprise a claw structure to ensure under this claw a compression of the lining in its thickness.

An example of a lining that is compatible with this embodiment is illustrated in FIG. 12. The decorative lining 4a comprises cooperation means 16a with the reversible fixing means 15 of the θ

structure. In this example, the cooperation means are constituted by notches 1 oa. The lateral lugs 15 can engage in these notches 1 όα, so as both to allow a transverse locking of the lining with respect to the rigid structure, and a pressure which tends to bend and push it towards the metal structure , which gives its veneer on the back side ensuring the desired aesthetic effect. To do this, the distance D 2 between the ends of the notches l 6a is slightly greater than the corresponding distance D 1 between the lateral lugs 15 along the rear face of the rigid structure 2.

More generally, the fixing means (the buttonholes 10 and the side portions 12, or the end lateral tabs 15 and the lateral tabs 1 2) apply a tightening of the lining in lateral directions of the plate: longitudinal along Tax connecting the buttonholes; and transverse along the axis connecting the lateral lugs located on the edges of the rigid structure, They ensuring a stress on the liner to maintain it without play in the structure and therefore without wear, and generate a pressure that splits at the bend and push back towards the metal structure, which gives its veneer on the back side ensuring the desired aesthetic effect,

The sheet of the structure 2 has a thickness of about 1 to 2 mm, the leather trim 4 a thickness of up to about 4 mm. We choose a slightly supple leather, having elasticity with a shape memory that allows it to resume its shape after bending. If necessary it is possible to make a stack of leathers assembled together giving a semi stiffness to the lining, with for example a central flexible core having a thickness of about 1/10 mm.

FIG. 2 shows the sheet of the structure 2 cut in a metal strip such as a steel or a brass, comprising over its entire surface aligned holes 14 having geometric contours, which may represent more than half of the total area. We obtain a simple graphic and refined, highlighting the patterns forming like a metal lace. It is also possible to use other types of cuts, for example to form writes.

The cuts of the structure 2 can also be combined with stampings or etchings on the metal surface of the sheet, to provide other decorative effects, such as writing, The structure 2 has a surface that can be polished, satin or matt , comprising a metal or a coating having a good mechanical strength as well as resistance to oxidation and chemical agents so as to maintain its appearance without wear and without alteration. In particular, a coating can be made of gold, silver, ruthenium, palladium or rhodium.

Figure 3 shows the leather lining 4, forming a substantially rectangular strip with rounded corners, comprising near each end a hole 1 6 disposed along the main axis of this band. Alternatively the bracelet may have a number of different buttonholes 10, for example one or three, It may also have none, the maintenance of the lining 4 being performed only by side lugs 1 2 and / or 15, the filling being pressed into the curved structure 2 by its elastic effect which tends to straighten it,

FIG. 4 shows the buttonhole 1 0 comprising a substantially spherical button 20, fixed to the sheet of the structure 2 by a short rod 22 welded vertically to this sheet, For a thin packing 4, the spherical button alone 20 can be fixed directly to the sheet of the structure 2, without rod, The piercing 1 6 of the liner 4 has a diameter slightly smaller than that of the knob 20.

For the assembly of the lining 4, the hole lo is placed above the button 20, as shown in the position A, then this lining is lowered by pressing it on the structure 2 so as to enlarge by deformation the material around the bore, and to come into position B resting on the sheet. The spherical shape of the button 20 facilitates its introduction to the piercing 10, and is a curved surface that is not aggressive to the wrist skin,

Adjusting the height of the button 20 according to the thickness of the lining 4, the vertical tightening of this lining by the button is then permanent, leaving it pressed against the sheet of the structure 2. FIG. 5 shows the side lug 1 2 of the structure 2, which forms a fold at 90 ° whose end 1S ends slightly below the upper level of the liner 4 so as not to exceed, so as not to irritate the skin of the wrist or catch something .

Figures 6a, 6b and 6c show the method of assembling the bracelet.

Figure 6a first shows the shaping of the liner 4, which is rolled to form a bend comprising a diameter slightly smaller than that of the structure 2 disposed below, shown in Figure 6b. The liner 4 is then lowered vertically by an axial sliding along the arrow 30, sliding in the structure 2 to abut on the lower side lug located below this structure. At this time the upper edge of the liner 4 also passes the upper side lug 12. The liner 4 is then adjusted between the two side portions 1 2, which form a lateral wedge in both directions.

Figure 6c then shows a pressure F applied inside the liner 4 at each buttonhole 1 0, to engage the buttons 20 in the holes of this lining. By providing a distance D2 between the two bores 1 6 of the liner 4 slightly greater than the distance D1 available between the two buttons 20 following the curvature of the structure, there is some lateral pressure of this lining in the sheet ensuring a maintenance and absence of play,

In general, the invention advantageously provides that the lateral distance D 1 between two fastening means (buttons 10 or end lalereal pastes 15), following the contour of the rear face of the structure 2, is smaller than the D2 corresponding distance on the liner 4, that is to say the distance D2, before fixing, antre points of the lining 4 on which will take the fixing means when the liner is fixed and plated on the face rear of the structure: distance D2 between two bores 16 (FIG. 3), or distance D2 between two end side bolsters 15 (FIGS.

This so as to ensure its lateral clamping and its plating against the rear face of the structure by these fastening means.

In addition, the shape memory of the somewhat elastic lining 4 tends to maintain its spacing inside the structure 2, which reinforces its plating in this structure. The mounting of the lining 4 simple and fast, without tools, ensures an effective positioning which is maintained in time,

A bracelet is obtained simultaneously having the shiny and luminous appearance of the metal structure 2, giving by its stiffness the general shape of the jewel, adorned with the holes 14 through which appears the leather trim 4 bringing color and color. sweetness. In particular one can choose a relief of the particular leather giving a luxurious appearance to the jewel, the combination of the two different technologies, the metal decorated with cuts having a metallic luster and the leather of the filling, coming from the know-how of two different trades, gives a contrast bringing a particular modern aesthetic.

The disassembly of the liner 4 can be done simply, by tying on its ends to disengage the buttons 20 of the bores 16, then tightening its bending to release side pattBS 1 2, to extract it by a axial flow. It should be noted that this disassembly is also done without tools, and without modifying or damaging any part.

Advantageously there are two different colors on both sides of the lining 4 which is reversible, which allows from the same lining mounted in one direction or the other to obtain two different effects on the same jewel,

Alternatively, it is possible to produce a lining 4 having 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 inside a plate having an elasticity to ensure bending and a shape memory,

It is also possible to produce a lining 4 which protrudes in places on the sides of the structure, to be visible and to give a particular aesthetic,

We can provide an individual sale of the gaskets 4 apart rigid structures 2, for example metal, which then allows to have a reduced cost of a large choice of aspects and colors. It is also possible to remove the lining 4, to wear only the metal structure 2, which gives an additional presentation variant. This is advantageously in the form of a decoration kit adapted to each rigid structure (a bracelet, a pendant, a ring, etc), and comprising a plurality of different aesthetically different gaskets 4 and each provided with cooperation means (the holes 16 or the notches 1 όα) with the reversible fastening means (the buttonholes 1 0 and / or the lateral lugs 12 and / or 15),

Figure 7 shows a ring comprising a sheet metal structure 2 wound in a small diameter to fit on a finger, which comprises rows of holes 14 forming a decoration. Rows of small bosses 48, formed by stamping, chemical cutting or etching sheet metal, complete the decor. In particular, chemical etching gives precise markings made economically.

The lining forming a strip 4 is inserted into the structure 2 of the ring after having been wound by elastic deformation. Cavities in the inner surface of the structure 2, turned towards the lining 4 and obtained by stamping, chemical cutting or etching over the entire surface of this lining, form a holding cage ensuring a clamping and locking to ensure its positioning and maintenance.

FIG. 8 shows a ring comprising a ring 40 designed to fit around a fingel, receiving by welding a circular metal structure 2 having in the center the rows of bores 14, and around a circular flange 42 forming a continuous bend facing towards the ring. The lining 4 is formed by a leather disc, which is inserted by fitting into a cage under the sheet of the structure 2. The ring of the ring 40 holds the lining in its housing so as to ensure its plating under the plate of structure 2.

Figures 9a and 9b show a jumper comprising a metal structure 2 slightly curved, having a crescent shape whose tapered ends strongly constrict to form a circular inner contour comprising a passage 46 allowing to fit the neck of the person.

The structure 2 comprises rows of holes 14, and between these bores rows of small bosses 48 made by stamping or chemical cutting of the sheet, adding decorative elements. Thus, in a single piece of cut sheet metal, a large metal structure 2 having a sufficient rigidity for this type of jewelry. u

The lining 4 is pressed on the rear face of the sheet metal structure 2 by three buttonholes giving a tightening of the lining against the sheet of the structure 2 to ensure its maintenance. FIGS. 10a and 10b show an ear pendant comprising a flat sheet metal structure 2, connected to a hooking needle 52 by a chain 50,

The structure 2 having rows of holes 1 4, has rear at its periphery 12 forming portions by interlocking inside the batchal clamping points of the liner 4, in order to keep it plated on the rear face of this structure.
