Description

Broadband Scope Field of the Invention

The present invention relates to a bezel with wide branches, at least one of the branches has an opening. State of the art

There are currently many forms of glasses with wide branches. If some branches are wide and full, there are others, cleared so that they are in Y-shaped lying, whose two legs are connected to the front of the branch by a cross with the hinge to join at the back by the end of the branch coming on the ear. Purpose of the invention

The present invention aims to develop glasses whose branches can be adapted and be brought into harmony with clothing elements or fashion trends. Description and advantages of the invention

To this end, the invention relates to a bezel wide branches of the type defined above characterized in that the inner face of the branch has fastening elements at the edge of the opening and a cladding plate of at least in part equal to the opening of the branch is provided with fixing members homologous to the fastening elements for releasably fixing the plate to the branch.

The dressing plate which occupies at least partly the opening of the branch, by its inner face, that is to say the face of the branch facing the user's head, appears through the opening and allows a wide variety of aesthetic effects. The attachment of the wafer being removable, it can easily be replaced by a wafer of another shape or another decoration. The decoration in the part of the plate appearing in the opening of the branch, can be a decoration flat or raised, in colors or monochrome. The wafer or that combined with one of the branches of the telescope advantageously comprises electronic and computer means such as a radio circuit, a telephone circuit or, more generally, connecting means capable of cooperating in WIFI.

Advantageously, the wafer incorporates an electronic chip or an RFID badge to enable identification of the wearer of the glasses, for example an access badge to a protected area such as an office area, an area in a company or even for detection passage, the authorization to use an installation or a machine, facilitating the management of surveillance for the wearer of glasses who will not have to worry about a badge. The badge itself standard format can be integrated into a reservation of standard format made in the plate which, it is adapted particularly to a certain telescope.

Finally, the pads can be varied and the user of a pair of glasses can have a set of pads, if necessary renewable, depending on the choices or necessities.

The wafer being a flat structure, it does not interfere with the wearing of glasses and does not constitute an obstacle protruding on the side of the inner faces of the branches.

Although the wafer may be opaque or transparent with patterns, inlays, inserts or other decorative elements intended to appear in the opening or in one of the openings if the branch has several openings, it is advantageous that the wafer covers the entire aperture and its dimensions are preferably such that the wafer placed against the inner face of the branch reaches substantially to the level of the upper edge and the lower edge of the branch.

The opening may be elongated and, in this case, the wafer will also be elongated. This elongated shape may be a triangular shape or a trapezoidal shape so as to leave the branch of the bezel, only a band at its upper edge and a band at its lower edge, these two bands joining together backwards by the end of the branch that comes on the ear.

The fastening elements carried by the branch and the fasteners of the wafer are preferably clipping means. Since the overall shape of the branch is triangular, it is advantageous to position these clipping means at the three corners of this triangular shape, two means at the hinge at the front of the branch and a means of attachment at the rear. , where the broad branch resumes a usual form. This fastening means at the rear can advantageously be split in the longitudinal direction of the plate and the branch.

The clipping pins are for example fixed to the plate by welding. They can also be constituted by pins forcibly engaged in the wafer. These fixing means, preferably elastic, easily engage in the holes made in the branch and constituting the fasteners at this level. These orifices are preferably non-emerging. However, for fixing reasons or aesthetic reasons, it may be advantageous to make outlets orifices and to give the clipping pins, a length allowing them to appear on the other side of the branch or to exceed . This structure is advantageous not only to ensure good fixing while remaining removable, but also for its decorative effect by the appearance of the ends of the pins. If the wafer and pins are metal, for example a polished metal or gold, the pins they will appear at their end at the outlet of the orifices constituting the fasteners in the wide branch.

It is also advantageous for the fastening elements to consist of two bent tabs at the front of the branch on the hinge side, these lugs being directed towards the rear of the branch and by a housing at the rear and that the fasteners are constituted by a tongue s' engaging longitudinally in the housing of the branch and by the front edge of the wafer which slips under the curved tabs rearwardly.

The introduction of the wafer is then done by adjusting the flexibility of the wafer since, after engaging the tab-shaped end of the wafer fastener in the housing at the rear of the branch, housing constituted for example by a kind of passer or jumper eventually opening, just bend the plate to slide under the curved legs at the front of the branch.

The plate is advantageously held in place by a cutout intended to cover the hinge element carried by the arm, the curved tabs or the fastening elements such that the snap-in orifices are located on either side of the element. hinge. This holds or blocks the wafer in the direction perpendicular to the longitudinal direction of the branch, in the plane of the branch.

According to another characteristic, the inner face of the branch carries fixing elements in the form of two bearings aligned on each side of the opening and a clipping element not located on the axis of the two bearings, bordering the opening, the plate is provided with fasteners formed of two pins aligned at each end of the wafer, and an engagement member forming the third attachment point to cooperate with the clipping element of branch. This method of fixing the plate to the branch of the bezel is interesting because easy to install and without risk of detachment since the plate is engaged by its two axes in the bearing and a third point of the plate is fixed by clipping. Even if at the clipping, the wafer emerges from the clip element, it can not be released, except to be deformed, bearings. This deformation of the wafer by bending to reduce the spacing of the axes is at the time of implementation of the wafer. The deformation is simple to achieve since it can hold with one hand, engage a pivot in his bearing and then bend the plate and engage the second pivot in his bearing, and when the plate is straightened, it can rotate around the axis thus formed to be clipped.

But this bending movement that must also be performed to clear the wafer and replace it with another wafer, is not a deformation that may occur naturally if the branch accidentally clings to an object.

This type of wafer and method of attachment of the wafer is particularly interesting for platelets of a certain price, for example wafers filled with jewelery such as stones, gilding or other.

Advantageously, one of the pivots is carried by an open tab of the body of the wafer to which it remains connected by a band of material forming an elastic connection for compressing the two pivots to bring them closer and engage them in the two bearings the branch, the establishment of the wafer being done by the introduction of the pivot of the flexible lug in its bearing and compression of the flexible lug to introduce the other pivot in his bearing and finally pivoting the wafer around the l Axis thus formed by the two pivots and the two bearings to snap the clipping member of the wafer in the clipping element of the branch, defining the mounting position of the wafer.

This embodiment of the wafer is particularly simple to install since after engaging a pivot in its bearing, to shorten the spacing of the pivots and allow the introduction of the second pivot in its bearing, the flexible arm is compressed at the level of its junction with the body of the plate, which forms an elastic connection, to gain length to get to enter the second pivot in his bearing. Then, the plate naturally returns to its state when release compression. The wafer may in this case also pivot about the axis formed by the two pivots to engage the clipping member in the clipping member.

To disengage from the clipped connection, simply push the plate through the opening of the branch of the telescope then clear the two pivots in the reverse order of movements described above.

Advantageously, the branch of the telescope comprises near its hinge, a pivot and an engagement element and the flexible tab carrying one of the pins of the plate also carries the clipping member of the plate, the other end of the wafer having the second pivot.

According to another advantageous characteristic, the bearing and the clipping element of the branch are made in the same part.

The pivot is a fastening element and occasionally pivoting or rotating, at the time of introduction of the wafer or its removal. This pivoting is perfectly possible even if the pivot has a non-circular section, for example if the wafer is cut from a sheet of rigid material such as plastic or metal, the square section of the pivot can then perfectly rotate in the cylindrical bore of circular section of the landing.

According to another characteristic, the two pivots and the clipping member are formed by portions of the strip of material in which the wafer is formed.

Thus it is the same with the clipping member which constitutes a part of the wafer.

According to another feature, at least one of the fastening elements is a gusset on the rear face of the branch and at least one of the fasteners at one end of the plate is formed by two tabs deforming resiliently in the gusset by compression in the longitudinal direction to allow to introduce the other fastener at the other end of the wafer in its fastening element of the branch.

According to another feature, the branch comprises two gusset-shaped fastening elements on the rear face of the branch and the two fasteners of the plate are made each one by two tabs elastically deformable by compression in the longitudinal direction.

This embodiment of the fasteners and fasteners allows a very simple and very effective implementation of the wafer on the branch. The implementation is done by playing on the elasticity of the two legs even in the case of a very rigid plate for example because of its particular shape, ribs and decoration that can carry the plate.

For certain types of decoration or structure of the wafer, it is desirable not to elastically bend the wafer but to keep its shape (flat or slightly curved naturally), according to the shape of the branch to which it fits. Deforming a wafer elastically beyond its natural shape can damage the decorative elements for example by creating cracks in the film covering the wafer or disconnect the inserts on the front face of the wafer.

The gusset-shaped housing provided at at least one of the ends of the bezel branch for receiving the fastening member in the form of elastic tabs of the wafer makes it possible to position the wafer flat against the back face of the the limb, first positioning the end provided with the elastic tabs in the gusset then pushing on this end to elastically deform the two branches and allow to pass the other end of the wafer, that is to say the fixing member of the other end of the wafer in its fixing element, for example a gusset similar to that of the other end; then releasing the end which has compressed the elastic tabs, the plate is finally set up while remaining removable. The gusset-shaped fastening elements can be very flat so as to form practically no relief on the inner face of the branch. These gusset-shaped elements can even be integrated in the rear face of the branch.

According to another advantageous characteristic,

- the opening is lined, on the inner side of the branch, a rabbet,

the fixing elements each consist of a housing at the edge of the opening, in the wafer, on the inner side, level with the inner side of the rabbet bordering the opening, the two housings are opposite one another, one of the housings being on the front side and the other on the rear side of the branch and at least one of the housings comprising a piston loaded by a spring ,

the plate has an edge intended to be supported by the interior of the opening against the rabbet,

the fasteners of the plate are each in the form of a tab extending the edge and intended to slide into the homologous housing of the opening, one of the tabs engaging in the housing provided with the piston, to push back the piston against the action of the spring until the other leg can be placed in front of the other housing, the release of the thrust exerted on the wafer in the opposite direction to the action of the spring of the piston, pushing back the assembly of the wafer to introduce the second leg in its housing and lock.

The wafer is introduced in a particularly simple manner into the opening in which it can lock. Any thrust exerted against the outer face of the plate is blocked. Only a translation movement exerted on the wafer parallel to the branch and so as to compress the piston makes it possible to release the other lug from its housing and extract the wafer to replace it, and change wafer to change the color or the decoration.

This movement is not natural and especially can not be caused accidentally, this virtually eliminates any risk of loss of the wafer, especially as the wafer is put in place by the inner side of the bezel branch.

According to another advantageous characteristic, the wafer has a convex shape corresponding to the opening of the branch, this convex shape being provided with the edge so that the convex portion is housed in the opening and the edge bears against the rabbet.

The curved shape of the wafer is provided with a sufficiently wide edge to allow the translational movement used to place the wafer in the opening without the respective dimensions of the opening and the curved shape interfering with the translation movement of the wafer to introduce the tabs. drawings

According to Figures IA, IB, the invention relates to a bezel wide branches. Only one branch 1 of the telescope is shown, showing its inner side 1. A wide branch has a shape enlarging from the rear end 11 passing on the ear to the front end 12 at the level of the hinge element 13 connected to the front part of the telescope.

This wide branch 1, relatively flat in its wide portion 14, has an opening 15 here constituted by an elongated slot extending over the entire length of the wide portion.

At the front and on both sides of the opening 15, the wide part 14 is equipped with two fastening elements 16, 17. At the rear of the opening 15, it comprises a third fastening element 18 .

These fastening elements 16, 17, 18 are intended to receive a plate 2 like that represented in FIG. 1B, provided with homologous fixing members 26, 27, 28 to the fastening elements 16, 17, 18 to cooperate with these and hold the plate of Figure IB applied against the inner side IA of the wide branch 1, so as to appear through the opening 15 thereof.

According to FIG. 1B, the plate 2 showing its outer face 2B intended to cover at least partially, and here totally, the opening of the wide branch coming against the inner side thereof, has a triangular shape whose apex is truncated. The dimensions of the wafer 2 are here greater than the dimensions of the opening 15 and, in particular, the upper edge 2 C and the lower edge 2 D of the wafer; FIG. 1B shows the outer face 2B of the plate 2 intended to come against the inner side IA of the wide branch 1. In addition to the fasteners, the plate has a cutout 29 so as to overlap the hinge element 13 by cooperating with the hinge element and thus constituting a locking means completing the maintenance by the cooperation of the elements 16, 17, 18 and the fasteners 26, 27, 28.

The elements and fasteners 16, 17, 18; 26, 27, 28 are constituted in this embodiment by means of clipping: the fastening elements 16, 17, 18 are housings, preferably non-emerging, made in the wide branch 1 and the fasteners 26, 27, 28 are snap pins, carried by the wafer 2. These snap pins can be made in the material of the wafer if the latter is a plastic or, more generally, a molded part. The clipping members may also be welded to the wafer or be inserted into the housing of the wafer by a tight fit so as to be secured.

These clipping means allow a removable connection of the plate 2 against the inner side IA of the branch 1.

The outer face 2B of the wafer 2 has decorative elements intended to appear through the opening of the wide branch. These decorative elements may be a decoration flat or raised at the level of the opening. According to a particularly interesting embodiment, the plate 2 is metal, treated, brushed, guilloche, tinted. The wafer advantageously incorporates functional elements such as an electronic telephone radio circuit or a computer support and in particular means working by WIFI.

In a very interesting way, the wafer may include an identification chip such as an RFID card which allows an eyeglass wearer to pass control points, for example protected areas of office or company to which he could not access with a badge for example RFID type, separate. This combination of the RFID badge and the bezel means that he always has the badge on him without having to worry about it.

Figures 2A, 2B show another embodiment of a wide-branched bezel according to the invention being limited as previously to a wide branch 101 seen from its inner side IA. This wide branch 101 has an elongated opening 1 15 of triangular shape along the contour of the wide branch. The wafer 102 for this opening 1 15 also has a triangular shape like that of FIG. 1B with substantially the same attachment means 126, 127, 128, i.e., connecting members, and a notch 129 for allowing to overlap the hinge element 1 13 carried by the wide branch 101. The assembly means may be clipping means as previously. For example, three points 1 16, 1 17, 1 18; 126, 127, 128 of the removable link are shown both on the inner side IA of the branch 101 and on the outer side IA of the plate 201 against the inner side IA IA of the branch 101 when the plate is in place on the branch.

FIGS. 3A, 3B show another variant of wide-branched bezel according to the invention. In this case, the wide branch 201 has, at its front portion 312 and its wide portion 314, a substantially trapezoidal contour with an opening 315 also trapezoidal shape. This opening is important. The wafer 302 for capping the opening 315 is shown in Figure 3B, in its assembly position, that is to say showing the inner face 302A.

Given the dimensions of the opening 315 and, consequently those of the wafer 302, it is advantageous to make the removable assembly of the wafer 302 and the branch 301 by four fixing points, two fixing points to the before 316, 317; 326, 327 completed by the duplication of the attachment point at the rear, these two attachment points 318, 3181; 328, 3281 being placed one behind the other. The wafer 302 also includes a cutout 309 for overlapping the hinge member 313 of the leg 301.

As before, the wafer 302 can be made of any material, preferably metal. Its exterior, decorative, is treated in colors.

FIGS. 4A-4E show another embodiment of a wide-branched bezel according to the invention. The principle of the wide branch 401 with an opening 415 intended to be occupied at least partially by a wafer 402 fixed against the inner side 40 IA of the branch 401, remains preserved but the removable attachment means of the wafer are modified.

Thus, according to FIG. 4A, the front 412 of the wide branch 401 whose opening 415 is of triangular shape comprises two lugs 416, 417 curved rearward 41 1 where the fixing point 418 is constituted by a passer or a housing.

The plate 402 of FIG. 4B intended to equip the flat branch 401 of FIG. 4A has a shape greater than the shape of the opening 415 and in particular a shape such that its upper contour 402C and its lower contour 402D correspond to the upper contours 40 IC and inferior 40 ID of the wide branch 401.

The rear end of the wafer 402 is provided with a tongue 428 intended to engage in the loop 418 of the wide branch 401, the front end 42 of the wafer coming under the two legs 416, 417 and for this purpose , the wafer 402 has a flat length which corresponds substantially to the distance between the front and rear fastening members 416, 417, 418. Thus, the wafer is set up by deformation, to be introduced into the legs turned towards the rear. This plate comprises a recess 429 for overlapping the articulation member 413

Figure 4C shows the inner side of the branch 401 provided with its plate 402.

Figure 4D shows more particularly the shape of the loop 418 and that of the front legs 416, 418 forming hooks.

Finally, FIG. 4E shows the external appearance of the wafer seen through the opening 415 of the wide branch 401.

FIGS. 5A-5C and 6A-6D show another embodiment of a wide branch 501 provided with a wafer 502.

According to FIG. 5A, the wide branch 501 comprises a hinge element 513 for pivoting about the axis zz with respect to the front of the frame. The inner face of the branch 501 carries three fasteners, namely two bearings 516, 518 aligned along the axis xx and a third fastening element 517 constituted by a clipping element.

The branch 501 has an opening 515 whose upper edge is represented under the axis xx without however this geometric arrangement is a necessity.

The wafer 502 intended to equip the branch 501 has a shape which, in this example, covers the opening 515 of trapezoidal shape of the branch 501.

The wafer 502 has two fasteners 526, 528 consisting of two pivots aligned along the axis x'x 'which, when the wafer 502 is put in place on the branch 501, will coincide with the axis xx under the conditions described below.

The wafer 502 comprises a third fastening member 527 constituted by an engagement edge designed to cooperate with the snap-fastening element 517 of the branch 501.

The body 530 of the wafer has a cut 531 intersecting the x'x 'axis and forming a flexible lug 532 by the material portion 533 which connects it to the body 530.

The free end of the flexible lug 532 carries the pivot 526 and the end of the lug located near the connecting portion 533 carries the clipping member 527.

The wafer 502 is placed on the branch 501 by engagement of the pivots 526, 528 in the bearings 516, 518 and then clipping of the clipping member 527 in the clipping member 517.

Once the wafer 502 is installed, the inner face of the arm 501 appears as shown in FIG. 5C. The wafer 502 completely or partially covers the opening 515. In this example, the opening 515 has a trapezoidal shape and the body 530 of the wafer 502 also has a trapezoidal shape of dimensions larger than those of the opening 515. However this geometric relation is not a necessity. Depending on the effect or result to be achieved, there will be a wafer and an opening that overlap partially or completely.

The introduction and removal of the wafer are as shown in Figures 6A - 6D.

According to FIG. 6A, the branch 501 of the head of the telescope must receive the plate 502.

In this example, the fixing element 516 forming a bearing and the fastening element 517 used for the clipping are constituted by a single piece, in the form of a bar carried by the inner face of the branch 501. The plate is shown separately. It consists of a piece cut in a sheet, the fasteners and the clipping edge being made during a single operation. The plate does not include decorative elements here.

It can be made with decorative elements on the face appearing the opening 515 of the branch and on the rear face.

According to FIG. 6B, by a first operation, the pivot 526 is slid into its bearing 516 while holding the body 530 of the plate between thumb and forefinger Once the pivot 526 is engaged, the body 530 is pushed in the direction of the axis x'x 'to bring the pivot 528 of the pivot 526 by deformation of the slot 531, until the pivot 528 is sufficiently close together to be able to engage in the bearing 518. Then releasing the compression so that the wafer returns to its natural state by relaxation of the deformation of the connecting portion 533.

The wafer then occupies the position shown in FIG. 6C. It can then be pivoted about the axis xx to pass the clipping member 527 under the clipping member 517. The plate 502 is thus held against the inner face of the arm 501 of the bezel.

To disassemble the wafer 502 and replace it with another wafer, it suffices to push through the opening 515 starting from the outer side of the branch 501 in order to disengage the engagement member 527 from the snap-in element 517 and pivot the plate around the pivot axis xx. When the wafer 502 is raised as shown in Figure 6C, it can be grasped between the thumb and forefinger and compress the flexible arm 532 by deformation of the connecting elastic 533 until one can remove the pivot 528 from its bearing 518 of the branch of the telescope (Figure 6B). it then suffices to simply extract the other pivot 526 from its bearing 516.

Although the broad branch embodiments presented in the above examples substantially correspond to a triangular shape, the invention is not limited to such a broad branch form. It applies generally to any branch of the bezel provided with at least one opening, this opening is elongated or other. A branch may also have several openings of which only one or a few receive a plate covering them partially or totally.

The openings in the branches can be symmetrical for the left branch and the right branch or be dissymmetrical.

Finally, the glasses may have branches of which only one has one or more openings receiving pads.

According to FIGS. 7A, 7B showing another alternative embodiment of a telescope with a variant of the fastening element 616 and of the fixing member: at one end 614 of the branch 601 and the plate 602, the means fixing the other end being similar or different. According to FIG. 7A, the telescope branch 601 comprises, at one of the ends 614 (here, the front end) on its inner face 60A, a gusset-shaped fastening element 616 represented by a rectangle but whose contour is embedded in the back side of the bezel branch. This gusset-shaped element located near the hinge 613 of the branch 601, receives the corresponding end of the wafer in its housing 601-1 whose opening 616-2 is turned towards the other end of the branch 601.

According to Figure 7B, the wafer fastener is constituted by two elastic tabs 626, 627 in the extension of the wafer. These elastic tabs, of curved shape, facing one another, can deform by compression in the direction (A) of their introduction into the housing 616-1 of the gusset 616.

The fixing means of the other end of the bezel branch 601 and the wafer 602 consist for example of a gusset-shaped housing into which a tab of the end of the wafer is introduced.

The plate 602 has on its face covering the opening 615 of the branch 601, decorative elements intended to appear in this window. These decorative elements are not represented.

FIG. 8 shows the position of the fastening element 613 and the fastener 626, 627 of the plate 602, engaged one inside the other, showing the rear face 60 IA of the branch 601 and the face rear of the wafer 602.

Figures 9A-9C show the successive phases of engagement of the fastener 626, 627 of the wafer 602 in the fastening element 616 of the branch 601.

Figure 9A shows the end of the wafer 602 applied flat against the rear face 60 IA of the branch 601 presented opposite the entrance 616-2 of the gusset 616 shown cut.

According to FIG. 9B, the end of the wafer formed by the two elastic lugs 626, 627 is introduced by sliding them into the gusset 616 and then compressing them to deform them elastically so as to advance the wafer in the direction of the arrow A of the length (e) necessary to place the other end of the wafer in its corresponding fastening element of the branch (this part of the branch and the wafer is not shown). The compressed form of tabs 626, 627 against the bottom of the housing 616-1 is shown in solid lines while the natural form of the tabs 626, 627 is shown in broken lines which allows to highlight the offset of the distance (e) between these two positions corresponding to the crushing and non-elastic crushing of the tabs 626, 627 under the thrust in direction A.

Then, once this other fastener placed in the fastener, releasing the thrust on the elastic tabs 626, 627 of the wafer 602 which return to their normal shape or possibly still slightly compressed (Figure 9C).

The wafer 602 is thus removably attached to the branch 601 and covers the opening 602 shown in dashed lines without the risk of lifting itself from the branch 601. To remove it, it is necessary to perform the reverse movement of that of the establishment, that is to say starting from the position shown in Figure 9C, it is necessary to push the plate 602 to the left (arrow A) to elastically compress the tabs 626, 627 in order to be able to release the other end of the wafer 602 of the second fastener. Then, once this end removed, it removes the end of the wafer provided with the two tabs out of the housing 616-1 of the gusset 616.

The other end of the wafer may also have a fastener constituted by an elastically deformable portion, similar to the two tabs of the end which has just been described and housed in a gusset of a shape corresponding to those of the gusset described herein. -above. This second end with a resilient fastener makes it possible to hold the wafer with some prestress in the two fastening elements of the branch 601, the dimensions being chosen so that the fasteners remain in a slightly compressed position. This makes it possible to compensate for a possible manufacturing game, which, even if it is very weak, risks being perceived in a troublesome way. This elasticity of the two legs also makes it possible to compensate for differences in expansion

According to FIGS. 10A, 10B showing another embodiment of a telescope, the branch 701 is provided with an aperture 715 of shape, here trapezoidal, with a rabbet 715a bordering the opening on all its sides or at least on a large part of these. On the front side and the rear side of the opening, towards the inner face of the branch 701, there is a housing 716 forming a fastener and a housing 717. provided internally with a spring-loaded piston 718 719, constituting the other fastener, opposite the first fastener 716.

The wafer according to FIG. 1 OB has a shape corresponding generally to that of the opening 715. This wafer 702 has a central portion 702b and a peripheral edge 702a intended to come into the rabbet 715a of the opening 715.

The front end of the wafer 702 is provided with a tab-shaped attachment member 726 which extends the edge 702a. The rear end of the plate is provided with a fastener 727 also shaped tab in the extension of the edge 702a.

The structure of this embodiment will appear more simply using the cross-sectional views of FIG. 1 IA-I ID.

Figure HA shows the shape of the rabbet 715a around the opening 715 with, on the front side, the housing 716 and, on the rear side, the housing 717, provided with the piston 718 loaded by a spring 718 which pushes the piston towards the 'before. The piston is retained by the rim 717a of its housing 717, the side directed towards the edge of the opening 715.

The housings 716, 717 are located on the inner side of the branch 701, in the edge of the opening 715 and are substantially flush with the rabbet 715a.

The cross-sectional view of FIG. 11B shows an embodiment of a wafer 702 having a central, eg curved, portion 702b with a peripheral edge 702a terminated at each end by a tab 726 and 727.

The introduction of the wafer in the opening 715 of the branch 701 is performed as shown in Figure 1 IC.

By a first movement passing through the inner face of the branch 701, the tab 727 is inserted into the housing 717 by pushing the piston 718 against the action of the spring 719 by acting in the direction of the arrow A until the end of the other leg 726 can be passed through the opening and be placed in front of the housing 716. At this moment, the thrust can be released in the direction of the arrow A so that the spring 718 pushes back by intermediate piston 717a, the tab 727 which pushes the plate 702 and the tab 726 in its housing 716.

The positioning movement of the wafer 702 consists in initiating the introduction of its tab 727 in the housing 717 by tilting the wafer in the direction of the arrow C to place it in the opening 715, its edge 702a bearing against the rabbet 715a. This support stabilizes the plate 702 and facilitates its thrust in the direction A to push the piston 718. The other leg 727 can then bear against the rabbet 715a in front of the housing 716. We can then remove the thrust on the plate that back in the opposite direction to the direction A and the tab 726 engages in its housing 716.

The end position of positioning movement is shown in Figure HD which shows that the two tabs 726, 727 are locked in their housing and resist thrusts exerted in the direction B perpendicular to the face of the branch. Whether this thrust is exerted by the outer side, which is also the most common, or the inner side of the branch 702, it can have a thrust component in the direction A may not unlock the plate 702.

To remove the wafer, the movement described above in FIG. 11 C is reversed by pushing the wafer 702 in the direction of the arrow A until the lug 726 is disengaged from the housing 717 and then by a movement of the pivot in the opposite direction to the arrow C, one can extract the plate.

This extremely simple movement allowing a very effective locking of the wafer facilitates the change of decoration or dressing of the bezel. The user of the bezel can thus have games of color pads or decors adaptable to different circumstances.
