Abstract

The compact disc support is based on a supple sheet cut to the diameter of a compact disc. There is a raised part (100,200) that fits over either the inside edge of the hole at the center of the disc, or over the outer edges of the disc. A flexible tongue (110) is formed adjacent to the raised part, to hold the disc on place against the support.

Description

The present invention relates to the field of media for discs

  recorded or intended to be recorded with data which

  can be audio, visual or computer data. The invention is intended, for example, for discs known under the name of compact discs.

  There are known compact disc storage boxes made up of two rigid leaves connected together by a hinge, one

  two leaves having in the central part a substantially circular member, intended to penetrate into the central orifice of a disc and forming pins 10 for retaining the disc over its entire periphery.

  Such cases have a high thickness compared to the thickness of a disc. These boxes are therefore too large to store

  large numbers of records. These boxes also have a high weight so that it is difficult to transport them in large numbers.

  To overcome these drawbacks, EP 479 556 has proposed a cover for a compact disc produced using two

  flexible plastic sheets intended to receive the disc between the two sheets. It is proposed in this document to provide one of the sheets with a central boss intended to be pressed inside the central orifice of the disc, this boss then retaining the disc against inadvertent sliding out of the cover.

  Such a pouch has several major drawbacks.

  On the one hand, it is not easy to extract a disc which is in place in the sleeve. Indeed, it is necessary to extract a disc to carry out two tedious operations, respectively to extract the boss of the disc by a pressure through the flexible sheets, and to open the cover to grasp the disc and take it out of the cover. The boss also forms an unreliable retention of the disc, in particular when the cover has passed through a stack of such covers. 3o On the other hand, the disc being retained between two flexible sheets, such a cover does not allow direct inspection of the disc, the disc being permanently veiled by the cover, which can make it difficult to choose a disc or make it impossible to read the inscriptions on the disc. The object of the present invention is to provide a compact disc support which does not have the aforementioned drawbacks. This object is achieved according to the invention thanks to a support for a data disc, this support comprising a flexible sheet intended to be applied

  against such a disc and a part intended to retain an internal or external edge of the disc, characterized in that the part intended to retain an edge of the disc consists of at least one flexible tongue.

  FIG. 49 is a front view of a support for a compact disc, comprising a suspension of the disc of compressible material;

  - Figure 50 is a cross-sectional view of the same device as in Figure 49.

  - Figure 51 shows in cross section a central part of a compact disc support provided with lateral suspensions of the disc; - Figure 52 is a front view of the same support as in Figure 52; Figure 53 is a front view of a support comprising a fabric part; FIG. 1 shows a flexible sheet of transparent plastic, with a thickness similar to that of traditional plastic pockets for storing A4 sheets in a filing cabinet. This flexible sheet has a disc shape of the same diameter as a compact disc. In the center of this sheet is made a

  cutout partially defining a member intended to be introduced into the central orifice of a compact disc. This cut forms in particular four corners10 110 or four right angles of a member 100 of rectangular shape.

  More specifically, such a rectangular member 100, the four corners of which are formed by cutouts of the flexible sheet, has an extent slightly greater than the diameter of the central orifice of a compact disc. More specifically, these four corners 110 are the four corners of a

  rectangle having a length greater than that of the internal diameter of a compact disc and having a width less than this diameter.

  In the preferred embodiment of Figure 1, the corners meet in pairs. Two corners of the same end of the rectangle

  are formed by cutouts which meet to form a rectilinear border at the end of the rectangle.

  From each of these four corners extends each time a notch 200 in a direction parallel to these end edges of the rectangle. In other words, each of these four notches extends across the width of the rectangle. Each notch 200 extends from an edge5 of the corner lying on a longitudinal edge of the rectangle, in

  distance from the rectangle, and along a length substantially equal to the width of the rectangle.

  As can be seen in the transverse view of Figure 2, the rectangle 100 further forms a depression in the flexible disc. In other words, the rectangle 100 is in a plane slightly raised relative to the plane of the rest of the flexible sheet. Such a sheet shape is easily obtained by molding or by hot deformation of

the flexible sheet.

  This preferential provision is however not necessary. The rectangle 100 can completely be in the same plane as the rest of the flexible sheet. The support of Figures 1 and 2 is used as follows: a compact disc is first positioned on this support so as to make the edges of the disc coincide with those of the flexible sheet. A user then holds the flexible sheet against the compact disc, for example between the thumb and forefinger of one hand, and, with his second hand, he applies a pressure of a finger on the flexible sheet and more precisely on the rectangle

  against the compact disc. The flexibility of the sheet 100 then allows a deformation of the zone of the sheet delimited by the notches 200.

  The rectangle 100 flexes in the form of a bump, the corners of this rectangle fading against the inner edges of the compact disc and the notches 200 opening to allow movement of the rectangle 100 through the orifice of the disc. while the rest of the flexible sheet remains on the same side of the compact disc. Thus, the notches 200 authorize, by their opening, the path of the rectangle 100 through the compact disc perpendicular to the rest of

  the flexible sheet remains in position.

  Once the rectangle 100 is inserted into the opening of the compact disc, the corners of this rectangle resume their position on the side of the disc which is opposite to the rest of the flexible sheet and the corners come to bear by elasticity on the inner edges, maintaining the flexible sheet against

compact disk.

  It is therefore understood that the support of Figure 1 is easily implemented on a compact disc. It protects an entire face of this disc while having a very reduced thickness and a particularly low production cost.30 To separate the disc from the support, it suffices to pull on the flexible sheet away from the disc and preferably perpendicular to the l1

disc plan.

  The corners of the rectangle 100 forming the tongues then flex and allow the rectangle to exit the orifice of the disc.

  FIG. 3 shows a flexible sheet similar to that of FIG. 1 and a rectangle 150 of the same dimension as the rectangle 100, the rectangle 150 being cut from a plastic sheet with a rigidity slightly greater than that of the flexible sheet. The rectangle 150 is preferably cut from a plastic sheet of the type of those forming the dividers of the traditional binders 10. This rectangle 150 is intended to be glued to the rectangle 100 in such a way that the corners of the two rectangles coincide with each other. The rectangle 150 thus forms a reinforcement of the rectangle 100 allowing an elastic return of the rectangle 100, once introduced into the orifice of a compact disc. A rectangle 100 cut from a flexible sheet and reinforced by such a rectangle 150 thus presents a faster and firmer elastic return. In Figure 4, there is shown a flexible sheet cut into a disc, and in the center of which are arranged cutouts partially delimiting an attachment member 300 of compact disc. The cutouts of this support form four corners 310, 320, 330 and 340 which, in this embodiment, do not define the corners of a rectangle but face each other in pairs, each pair of corners defining the ends of a eye or almond shape. Thus, a couple of corners 310 and 320 have their respective openings facing each other, these two corners being spaced from each other by a distance slightly less than that of the diameter of the orifice. central of a compact disc. Similarly, a pair of corners 330 and 340 is arranged in the same way, and symmetrically at the first two angles with respect to a diameter of the support. The two pairs of corners 310/320 and 330/340 are spaced apart. one from the other from a distance slightly greater than the diameter of the central opening of a compact disc. In addition, within each pair of corners 310/320 and 330/340, the two corners join together by a cutout extending

one of their sides.

  More precisely, this cut connects the sides of the corners which are furthest from the center of the support. These cutouts connecting the corners of each pair describe a circular curve centered on a central point of the support. Thus, each pair of corners and its corresponding connecting cutout form a tongue extending away from the center of the support and whose end edge forms a circular curve, this circular curve having in the present case an angular extent of approximately 1200.

  The ends of the two tabs are spaced from each other by a distance greater than the diameter of the orifice of a compact disc.

  In addition, each corner 310, 320, 330 and 340 has its end point extended by a rectilinear notch 315, 325, 335 and 345 aligned with the

  side of the corner that is closest to the center of the support. This extension cut extends from the end of the corresponding corner over a length substantially equal to the length of the side which extends towards the center 20 of the support.

  Thus, the cutouts in Figure 4 delimit, inside the four corners previously described and circular cutouts connecting in pairs

  these corners, a member intended to be inserted inside the orifice of a compact disc, this member having a length greater than the diameter of the orifice of a disc and a width less than the latter.

  A user applying a pressure of a finger on the central member 300 thus defined against the orifice of a compact disc produces a deflection of the two tongues of the member and an elevation of the member perpendicular to the support through the disc hole until the tabs return to position on one side of the disc opposite the support, pressing against the edges of the disc hole. During such an operation, the displacement of the organ through the orifice and away from it

  the rest of the support is authorized by the opening of the additional notches 315, 325, 335 and 345 which in particular allow the displacement of the four corners of the member 300 away from a main surface of the support.

  Such an organ geometry has the advantage, by its two circular edges centered on the center of the support, of providing a bearing surface

  of the member 300 on the edges of the orifice of the disc which has an extent greater than that provided by a member having the geometry of FIGS. 1 to 3.

  FIG. 5 shows a geometry of an organ cut from a flexible sheet, also having four corners 410, 420, 430 and 440, which differ from the geometry of FIGS. 1 to 3 in that the four corners each have a angular opening less than 90 .15 One of their sides is aligned with an end edge of a rectangle, and these sides of the corners forming the end edge of a rectangle joining

  towards each other in the same end cut of the rectangle. Unlike the device in FIGS. 1 to 3, these corners have their second side not aligned with the longitudinal direction of the rectangle but extend slightly towards the inside of the rectangle at an angle of approximately 60.

  This device also has notches 200 extending from an unaligned side of each corner, away from the rectangle, these notches

  all having the same direction, parallel to the end edges of the rectangle.

  Such a geometry has the advantage, compared to the device of FIGS. 1 to 3, that the ends of each corner 410 to 440 are provided to flex along an axis of flexion substantially tangent to the edge of the orifice of the disc intended to be in contact with these corners. The support presented in FIG. 6 differs from the support in FIGS. 1 to 3 by the fact that only two notches 200, again having the function of authorizing movement of the member away from the rest of the support,

are adopted in this device.

  More specifically, this device has four corners 210, 220, 230 and 240 forming, as in Figures 1 and 3, four corners of a rectangle, these corners joining in pairs by one of their sides forming an edge s d end of the rectangle. This support has two rectilinear notches 200 each having a length substantially equal to the width of the rectangle, which extend from the corners of the same end pair in a direction parallel to the end edges of the rectangle, starting from an edge of each corner that is aligned with the longitudinal direction of the rectangle. In addition, each of these notches has at its end opposite to the rectangle an extension of notch 205 perpendicular to the notch considered, extending over a small distance in a direction of approach to the center of the support. A second pair of corners 230, 240 does not exhibit such

  notches 200 so that the displacement of a tongue formed by a pair of corners is facilitated in this device only on one side of the rectangle.

  The device of Figure 6 is intended to be used by introducing into the orifice of a disc the member partially bounded by the corners 210, 230 and 240 in two successive stages. First the tongue formed by the corners 230, 240 is introduced into the orifice of the disc, by pressing with a finger on this tongue. In a second step, the second tab formed by the corners 210, 220 is introduced into the orifice, this second introduction being facilitated by the opening of the notches 200. The extensions of notches 205 have the effect of preventing a

  possible tearing of the end of the notch 200 which is opposite the corner, during this second introduction.

  Such a device has the advantage that the first tongue not extended by notches has an elastic return towards the support which is firmer than that of a tongue extended by notches. The user can also introduce the tongue 230/240 not only by pressing on this tongue but also by moving the support parallel to the compact disc, the tongue 230/240 penetrating

  into the disc orifice by a combined movement of bending perpendicular to the support and of translation parallel to the disc through the disc orifice. The second tab is then introduced only once this translation has been completed, that is to say once the edges of the support coincide with the edges of the compact disc.

  The support of Figure 7 has a member defined by four corners inscribed on the corners of a rectangle. As for the device of FIGS. 1 to 3, these corners have their two sides inscribed respectively, on a side lo end of the rectangle, and on a longitudinal side of such

rectangle.

  The edges inscribed on the end side of the rectangle meet, forming a cut delimiting the end of the rectangle. The edges of

  corners which are inscribed on the longitudinal direction of the rectangle, do not meet from one end corner to a corner of another end, one with 15 Is the other.

  In this device, openings have been made on each side of the rectangle, near each of its longitudinal edges.

  These openings both have the shape of an equilateral triangle, a base of which extends parallel to the longitudinal edges of the rectangle. These triangles thus point away from the rectangle in the direction of its width. These openings 510 and 520 are arranged so that their base parallel to the rectangle is at a distance from the corresponding longitudinal edge which is substantially equal to half the width of the rectangle.25 These two openings have the function of authorizing a displacement of the organ partially delimited by the corners 210, 220, 230 and 240, in

  away from the rest of the flexible support.

  More precisely, each of these openings 510 and 520 deforms, when a user applies a pressure of a finger on the rectangle

  partially delimited by these corners, so that two edges of each triangle approach each other.

  More precisely, the two edges of each triangle not aligned with the main direction of the rectangle close one on the other and the base of each rectangle deforms in deflection to allow the rectangle to rise from the main plane of the support. 5 These openings therefore provide increased flexibility of the flexible sheet in the vicinity of the longitudinal edges of the member.

  hooking delimited by the corners 210 to 240. Figure 8 shows in exploded view a support consisting of two pieces glued one on the other.

  The first is a flexible sheet of the same size as a compact disc. This flexible sheet has in the central part two notches parallel to each other, extending over a distance substantially equal to one third of the diameter of a compact disc, these two notches being spaced from each other by a distance slightly less than the diameter of the orifices 15 of a compact disc. In the central part of the zone delimited laterally by these two notches is stuck a rectangular plate of plastic material 650. This rectangle 650 is for example a plate cut out from a sheet of plastic material constituting the dividers of a standard filing cabinet. This rectangle has a length slightly greater than the diameter of the orifice of a compact disc and a width slightly less than such a diameter. This plate 650 is arranged so as to extend perpendicular to the notches 610, 620 and is not stuck on the disc of

  flexible sheet only in the area delimited by the two notches 610 and 620.

  The plate 650 is also placed in the center of the support, so that it extends by its two ends beyond these notches, this part protruding from the notches forming tongues which are not fixed to the flexible sheet. user applies finger pressure to the face of the flexible sheet opposite to that carrying the member 650 to produce a separation of the member 650 from the rest of the flexible sheet moving through

  the central hole of a compact disc. The rectangle 650 then deforms by bending through this orifice and the tabs formed by the ends of this rectangle take place in abutment on the edges of the orifice5 on the face of the disc which is opposite to the flexible sheet, thus producing a catching media on the compact disc.

  It is understood that such a device is particularly simple to produce, while producing an ease and an efficiency of attachment of the support to the compact disc which is entirely satisfactory. The support of FIG. 9 is produced from a flexible sheet cut according to the principle explained above according to which

  cut from this sheet four corners of an elongated rectangle, the corners joining two by two, each time forming a transverse end cut of the rectangle which extends over the entire width of the latter.

  This support also has notches 200 extending perpendicular to the main axis of the rectangle from the edge of each of the corners which is parallel to the length of the rectangle. These cutouts of the support have in the case of the support of Figure 9 the particularity that the rectangle partially delimited by these corners is of a length much greater than the diameter of the central orifice of a compact disc. More precisely, the length of the rectangle thus delimited is substantially equal to one and a half times the diameter of a disk orifice

compact.

  Once these cuts have been made, the two tabs each defined by a pair of corners 210/220 or 230/240 are each folded back on themselves towards the inside of the member, the two parts of each folded tab being glued together. one over the other, so that each folded tab forms a new tab of thickness equal to twice the thickness of the flexible sheet. Such folded tabs have

each improved stiffness.

  The cutouts forming the initial tabs have a geometry such that the folded tabs have their respective ends spaced from each other by a distance greater than the diameter of the central orifice of a compact disc. Thus, the organ forms, by these two tongues, a rectangle suitable for hooking the support in the orifice of the compact disc. The notches 200 extend from the longitudinal edges of the corners 210, 220, 230 and 240 from a point on each of these edges which is

  sufficiently close to the center of the disc so that these notches open on a lateral side of the folded tabs.

  Thus, the notches 200 effectively fulfill their role of softening in deformability of the central zone of the flexible sheet,

  and effectively allow movement of the tabs away from the flexible sheet.

  The support of Figure 10a is made from a flexible sheet having two notches 610 and 620 arranged in the same manner as in Figure 8, that is to say two notches parallel to each other arranged with on either side of the center of the flexible sheet. The notches 610 and 620 are spaced from each other by a distance which is here equal to or slightly less than the diameter of the central orifice of a compact disc so that

  that the part of the sheet delimited by these notches can penetrate this orifice when the support is put in place. These two notches 610 and 620 each extend over a distance substantially equal to one third of the diameter of a compact disc.

  In the central part of the area delimited by these two notches is stuck a member 700 intended to be introduced into the central orifice of a compact disc. This member 700 consists of two parts, both substantially flat. A first part is a layer 710 of double-sided adhesive 30 glued directly to the flexible sheet. This first part is of substantially circular shape and of diameter substantially equal to that

  of. the central hole of a compact disc.

  On the face of this piece which is opposite the flexible sheet is bonded a plate 720 of flexible plastic. Plate 720 presents

  even a substantially circular shape, and it is slightly larger in diameter than that of the central orifice of the compact disc. It therefore extends laterally to the adhesive layer 710, forming by its protruding parts latching tabs for a compact disc. More specifically, this circular plate is truncated in two diametrically opposite zones of this plate, so that the plate has two straight edges parallel to each other. The plate 720 is placed so that these rectilinear edges are placed in parallel, and

  preferably confused with the two notches 610 and 620 of the flexible sheet. These two rectilinear edges are spaced from the center of the plate by a distance slightly less than the diameter of the orifice of a compact disc.

  In the same way as for the supports described above, the member 700 is intended to be introduced by a user through the central orifice of a compact disc, by pressing a finger on the face of the flexible sheet which is opposite this member 700. During such an operation, the movement of the member 700 perpendicularly to the rest of the flexible sheet is authorized by the opening of the notches 610 and 620, that is to say by bending of two bands laterally delimited by these notches located on either side of the organ and connecting the organ to the rest of the flexible sheet. During this operation, the plate 720 comes to bear at its edges on the inner edges of the central orifice of the compact disc and, by bending against these edges, crosses these edges to come to extend again, by elastic return, on the side of the compact disc which is opposite the flexible sheet. The deformation of the plate 720 is facilitated by the fact that the layer 710 is advantageously a layer of foam which can be compressed. Such a layer thus facilitates the flexing of the plate 720 forming tongues

  hooking when it enters the hole of the compact disc.

  The layer 710 advantageously has the thickness of a compact disc, so that once the plate 710 has passed through the orifice of the

  compact disc, this is recalled by the layer 710 pressing against the disc 5, opposite the flexible sheet, the distance between the plate 720 and the flexible sheet corresponding exactly to the thickness of the compact disc.

  The extent of the plate 720 is chosen by those skilled in the art according to the flexibility of this plate to allow easy passage of

  this plate in the orifice without however allowing too easy an exit delo the member 700 out of the orifice of the disc.

  The use of double-sided adhesive foam to form the layer 710 has the advantage of allowing easy assembly of the

  overall device. However, layer 710 can be replaced by any part made of any other material, including a rigid material. 1 5 We have proposed in Figures 10b to 10m different variants of geometries that can be adopted for the member 700.

  In FIG. 10b, a plate 720 of square shape is proposed, the length of one side of this square being slightly less than the diameter of

  the orifice of a compact disc but sufficiently large for a diagonal of this square to be greater than the diameter of the orifice of a disc.

  In FIG. 10c, an underlying layer 710 is proposed which is particularly suitable for a square plate. Such a layer is of substantially circular shape truncated according to two segments 25 parallel to one another and equidistant from the center of the general circle delimiting the part 710. The part 710 thus has two opposite edges in arcs of a circle forming catching tabs, and two other opposite edges, of rectilinear shape and parallel to each other. The straight edges are closer to the center of the part 710 than the edges in arcs. The diameter of this piece 710 at its edges in arcs of a circle is

  equal to that of the orifice of a compact disc.

  The part 710 of FIG. 10c is advantageously glued to the part 720 so that its rectilinear edges are 45 with respect to the side of the square 720 of FIG. 1 Ob. Thus, each of the rectilinear edges of the part 710 form a bending line for the corners of the square 720 which5 protrude from this part 710 at its rectilinear edges and which

  thus form hooking tabs.

  FIG. 10d presents a plate 720 in the form of an almond truncated at its two ends along rectilinear edges. The transverse extent of this almond is slightly less than the diameter of the orifice of a disc while the length separating the two rectilinear end sides of this almond is slightly greater than the diameter of the orifice of a disc

  compact, so that these ends form hooking tabs. FIG. 10e shows a layer 710 in the form of a disc of the same diameter as the orifice of a compact disc.

  In FIG. 10f, there is again presented a plate 720 of square shape, of the same dimensions as those of plate 710, advantageously associated with a layer proposed in FIG. 10g which has a disc shape from which four portions have been taken up, distributed uniformly. around this part, each portion having a substantially circular contour, so that the layer of FIG. 10g has a shape extending from its center in four languages separated from each other each time by an angle of 45. The plate of FIG. 10f and the layer of FIG. 10Og are advantageously associated with each other so that the corners of the square of FIG. 10f extend from the layer to the level of the truncations of this layer, that is to say between two languages of the underlying layer, thus forming hooking tabs. Thus, a bending of each of the corners of the square of FIG. 10f is in no way hampered by the presence of a portion of the layer of FIG. 1 Og under this corner. In FIG. 10h, a plate 720 is proposed associated to a layer 710, the latter being hatched. The plate 720 has a disc shape extended by two languages at diametrically opposite zones, and the layer 710 is present under this plate only at its circular central part. In FIG. 10 i, the plate 720 is square in shape and is placed on a layer 710, also having the shape of a square, and offset angularly from the plate by an angle of 450 so that the corners of the plate 720 correspond to the sides of the square 710, for better bending efficiency of the plate 720. FIG. 10J proposes a plate 720 of square shape placed on

  an underlying disc-shaped layer, the disc 710 having a diameter equal to the length of the side of the square 720.

  In FIG. 10L, there is provided a plate 720 having a substantially rectangular shape whose end sides have been rounded. The layer 710 associated with this rectangle is circular in shape. In FIG. 10m, a form of plate 720 in the form of an almond is proposed, the ends of which have a slightly rounded angular shape, the distance separating these ends being greater than the diameter of the opening of a compact disc. This plate is associated with a layer 710 forming a disc of diameter equal to the width of the almond forming the plate 720.20 In FIGS. 11 to 13, a support is provided formed of a flexible sheet of the type with two parallel notches delimiting an area central of the flexible sheet forming a flexible strip. Between these two notches is placed a member 800 formed of a substantially circular and rigid part, traversed by three flexible fibers 820, 830, 840 of length greater than the diameter25 of the central orifice of a compact disc. The organ is therefore fixed by a part of the flexible sheet which is connected to the rest of the sheet by two strips of sheets delimited by notches. More specifically, the rigid part 810 is traversed by three parallel channels into which the three fibers 820, 830, 840 are introduced. These three fibers have sufficient flexibility to be deformed, so that the ends of the fibers are erased in bending against the edges of the hole in the compact disc. Reservations are planned for this

  effect in the rigid part 810. Thus the part 810 has two cavities 812 and 815 at the mouths of the channels receiving the fibers and inside which the ends of the fibers can be folded back when the support is placed on the compact disk.

  As can be seen in FIG. 12, the fibers 820, 830 and 840 are arranged at a distance from the flexible sheet which is substantially equal to

  the thickness of a compact disc 900, so that the fibers having passed through the orifice of the compact disc come to rest by elasticity against this compact disc, keeping it in abutment, without play, against the flexible sheet.

  Advantageously, the notches of the flexible sheet have a spacing between them which is equal to the diameter of the orifice of a disc.

  compact, and the member 800 is placed between these notches so that the ends of the fibers 820, 830 and 840 protrude from the notches of the flexible sheet away from the center of the flexible sheet.

  The support of Figures 14 and 15 is again made from a flexible sheet of the type with two notches defining a central strip of the flexible sheet. On this central strip is placed a layer 710 in the form of a disc with a diameter equal to that of the orifice of a disc to be supported. On this layer 710 is bonded a plate 720 also in the form of a disc, this time of greater diameter. to that of the central hole of a compact disc. The plate 720 has in this embodiment radial cuts of length substantially equal to a quarter of the diameter of the plate

  720, and angularly distributed uniformly on the circular edge of the plate 720.

  More specifically, the plate 720 has ten notches 725 which form fringes or tongues distributed over the entire contour of the

  plate 720. Such a plate 720 has improved flexibility, allowing the use of a relatively rigid material to form such a plate and thus exhibiting increased strength.

  In addition, the adoption of such fringes on the contour of the plate 720 allows a deformation of this bump-shaped plate, without significant effort from a user, such a form of bump being particularly suitable for its introduction into the orifice. of a disc. 5 In FIG. 16, there is proposed a member 700 intended to pass through the orifice of a disc, consisting of a layer 710 made of rigid plastic, and of a plate 720 made of elastic plastic. The part 710, of thickness substantially equal to the thickness of a compact disc, has the general shape of a cylinder having four cavities distributed at an angular spacing of 45 around this cylinder. These four cavities, referenced 712, 714, 716 and 718, have the function of receiving tongues formed by the plate 720, when these are bent in proximity to the flexible sheet carrying the member 700. The plate 720 thus has four tabs 722, 724, 726 and 728 which extend from a substantially circular central shape of the plate 720, this circular central shape having a diameter less than that of the orifice of the disc. The tongues 712, 724, 726 and 728 each protrude from this central part of the plate 720 so that the ends of two diametrically opposite tongues are spaced apart from each other by a distance greater than the diameter of the orifice d 'a compact disc. The tabs can be folded back by bending inside each of the corresponding cavities 712, 714, 716, 718. The plate 720 and the layer 710 each further have a central through hole 730 intended to allow the plate to be fixed.

  720, layer 710 and the flexible sheet of the support by means of a rivet passing through these channels 730.

  FIGS. 17 and 18 represent a variant of such an organ of the underlying layer type provided with cavities and with a plate 720 provided with tongues

  opposite the cavities. In this variant, the plate 720 only has two diametrically opposite tongues 722 and 724.

  Figure 19 shows a support made from a flexible sheet

  in which two windows or recesses 810 and 820 are produced.

  Each of these two openings 810 and 820 is a rectangle of length substantially equal to the diameter of the orifice of a compact disc and of width substantially equal to a quarter of the length of one of these 5 rectangles. These two rectangles therefore form two elongated openings. They are arranged parallel to each other, on either side of a central zone of the flexible sheet, at a distance from one another which is such that the centers of each of these openings are spaced from each other by a distance equal to the diameter of the central orifice of a compact disc..0 On the area delimited by these two openings 810 and 820 is stuck a square plate 720 forming a member intended to hang a compact disc by its positioning through the central orifice of such a disc. In this variant embodiment of the invention, the openings 810 and 820 are intended to open when a user presses the plate 720 through the orifice of a compact disc, the longitudinal edges of each of the rectangular openings s' moving away from each other when a user presses the member 720 away from the rest of the sheet. The device of Figures 20 and 23 is made from a flexible sheet in which, as shown in Figure 23, have been provided

  four notches 1010, 1020, 1030 and 1040 substantially rectilinear and extending radially on the flexible sheet.

  More precisely, these four notches extend each time from a point on the flexible sheet which is distant from the center of the sheet by a distance substantially equal to the radius of the orifice of a compact disc. The notches 1010, 1020, 1030 and 1040 extend over a length substantially equal to the diameter of such an orifice. In the case of the device in FIGS. 20 and 23, these notches also have the shape of a triangle of small width, so that all four form an elongated slot. 30 On the central zone from which extend these four notches 1010, 1020, 1030 and 1040 is fixed a layer 710 in the form of a disc, surmounted by a plate 720, itself in the form of a disc, substantially conforming to the embodiment of FIG. 10Oa. The notches 1010 to 1040 have the effect of producing a softening of the flexible sheet at the edge of the member 700 to facilitate its insertion into the central orifice of a compact disc. The triangular shape pointing away from the organ is again particularly advantageous from the point of view of this softening of the sheet. FIGS. 21 and 22 show a variant of a support with a member comprising a layer 710 and a plate 720, and with notches extending in radial directions from a central zone of the support which carries this member 700. As can be seen in FIG. 22, in this embodiment, the four radial cuts 1010, 1020, 1030, 1040 form two pairs

  1010/1040 and 1020/1030 in which pairs the two notches are connected by a circular arc cut 1050, 1060.

  Each arcuate cut connects the end of each of the notches forming a pair, with their ends pointing towards the center of the flexible sheet. The pair of notches 1010 and 1040 spaced from each other by 20 45 is connected by the notch 1060 and the two notches 1020 and 1030 are themselves connected by the circular arc 1050. Thus, the initial cutouts of the sheet 22 have two circular arcs 1050 and 1060, these arcs having the same center as the flexible sheet, extended at their ends by rectilinear and radial notches 1010,1020,1030 and 1040.25 Thus, the cutouts of the flexible sheet form two assemblies which each form a border of a central strip 1070 of the flexible sheet 1070. Inside this central strip, and more precisely inside a circle partially delimited by the two arcs 1050 and 1060 is glued

  the member 700 shown in FIG. 21, the member 700 having an underlying disc-shaped layer 30 whose edges are substantially inscribed on the circular arcs 1050 and 1060.

  According to a variant of the invention, the plate 720 bonded to this underlying layer can have any type of geometry such as those proposed previously in FIGS. 1 Oa to 1 Om. Thanks to the device proposed in FIGS. 21 and 22, the notches extending radially from the member provide softening of the sheet in the vicinity of this member, allowing movement of the latter through the compact disc, but these notches 1010, 1020, 1030, 1040 constitute two bands which carry the member to the rest of the flexible sheet, so that a bending movement of these two strips further accentuates the deformability of the flexible sheet in the vicinity of the member. These two strips each extend diametrically opposite from the member, connecting the latter to the flexible sheet. Thus, when the user exerts pressure on the member away from it from the rest of the flexible sheet, each of these two bands has a deviation from the rest of the flexible sheet which is such that the member is placed in a second plane, offset from that of the rest of the flexible sheet, these two planes being connected by each of the two strips. The device of Figure 24 is made from a flexible sheet in which is formed a central window 1100 of rectangular shape. This rectangle has a length substantially equal to the diameter of a compact disc and a width substantially equal to one fifth of its length. On either side of this rectangle 1100 are arranged two studs forming the sub-parts of the same fixing member 700 inside the orifice of a compact disc. Each of the layers 717 and 719 has a semi-disc shape. More specifically, each of these layers has a form of

  half-disc whose rectilinear edge is practically coincident with a longitudinal edge of the central opening 1100 of the flexible sheet, the edge in an arc of a circle of each of these layers being opposite to the opening 1100.

  On each of these layers 717, 719 is bonded a flexible plate 727, 729, of elongated rectangular shape, having a length substantially equal to that of the opening 1100, a longitudinal edge of each of these plates being coincident with a corresponding edge of

the opening 1100.

  Thus, the plates 727 and 729 extend beyond the corresponding layers 717, 719, away from the opening 1100, thus forming each time a tab of lower bearing surface intended to come against an edge of the orifice central of a compact disc. More specifically, in the resting arrangement of the support sheet,

  i0 element 700 has an extension slightly greater than that of the orifice of a compact disc, the assembly formed by the two sub-layers

  adjacent 717 and 719 having a general diameter substantially equal to the diameter of the orifice of a compact disc and the plates 727 and 729 extending away from the center of the sheet over an area 15 greater than that of the diameter of a compact disc.

  The present support has the particular advantage that the opening 1100 allows the two elements 727 and 729 to be brought towards one another. By such approximation, the assembly member 700 formed by the two elements, each consisting a layer and a top plate, this

  element 700 has a reduced extent relative to its position when the opening 1100 is in its initial arrangement.

  When the two elements forming the member 700 and separated by the opening 1100 are brought together, so as to close the opening 1100, for example between the thumb and the index finger of a user, or 25 by general pinching of the flexible sheet, these two elements form an organ whose extent is less than that of the central orifice of a compact disc. Thus, the organ can be easily engaged in the orifice of the disc. The member 700 proposed in FIGS. 24 to 26 can also be placed on a compact disc by first introducing one of the two studs forming this member by simple pressure of a finger at this stud on the face of the sheet opposite to this pad then by printing a translation on the flexible sheet in its half carrying the second pad not yet introduced, so as to bring the two pads together then, in a third and last operation, by printing a pressure on the second pad to move it through the hole in the CD. To facilitate such manipulation of the support, the flexible sheet advantageously has a rough surface on the face opposite to

  the member and in the vicinity thereof, so that a user can cause the sheet to slide against the disc with a finger, while keeping good adhesion of the finger to the flexible sheet.

  The flexible sheet then resumes its initial flat shape, the two studs forming the member 700 each coming to bear in an opposite manner, inside the orifice of the compact disc. In Figure 27, there is shown in cross section a second alternative embodiment of a central opening device 1100 in which each of the two studs constituting the member 700 is constituted by

  a plate 720 fixed on a boss 770 whose upper face is flat. Such bosses 770 can easily be produced by molding the flexible sheet. The planar upper face of this boss is in a plane 20 offset from the plane of the rest of the flexible sheet by a distance which is preferably equal to the thickness of a disc.

  FIG. 28 shows a member 700 produced in accordance with this latter variant. In this embodiment, a V pinching member, referenced 1300 is placed in the opening 1100.25 This V member is a plate folded in its center so as to form the two leaves of a V. At the ends of the branches of this V, this plate is folded so as to form two tongues 1330 and 1340 moving away from the center of the V. The V-shaped part 1300 is fixed in the opening 1100 by gluing of the tongues 1330 and 1340 on the flat surfaces

  upper end of bosses 770.

  Thus, the V crosses the opening 1100, the point of this V protruding from the flexible sheet at its lower face and the branches of the V protruding from the flexible sheet on the upper face thereof and coming to stick on the bosses 770 by means of the tongues 1330 and 1340. In this embodiment, the tongues 1330 and 1340 have a width sufficient to project bosses 770 away from the central opening 1100, so that each of these tongues 1330, 1340 fulfills the same function as the plates 727, 729 previously described in relation to FIGS. 24 to 26, of constituting lower bearing surfaces, intended to come against the edges of the orifice of a disc. 10 Such a device allows the user to pinch between the thumb and forefinger the part of the piece 1300 in V which protrudes from the underside of the flexible sheet. Such pinching produces a bringing together of the two bosses 770 towards one another so that the opening 1100 closes on itself by bringing together its longitudinal edges. The two studs of the member 700 are thus brought closer to one another so that the member 700 has an extent smaller than that of the orifice of the compact disc. It can then be introduced inside this orifice, still maintaining the support between the thumb and the index finger by means of the V-piece 1300. Once each of the studs of the member 700 introduced into the orifice, the user releases the V-shaped part and by elastic return of the latter, each of the two studs of the member 700 comes to bear against the inner edges of the orifice of the compact disc, the support thus being hooked to the disc. It is therefore understood that such a device is particularly easy to set up. The device of FIGS. 28 to 30 further presents the possibility of being stacked support on support, whether these supports are provided with a compact disc or not. As can be seen in FIG. 28, the V-shaped piece of a given support advantageously fits into the V-shaped piece of a support placed directly under the first support, so that the fact that the V-shaped piece protruding on one side of the flexible sheet in no way alters the storage possibilities of the compact discs in a binder whose flexible sheets would constitute the pages. The device of FIG. 31 is produced from a flexible sheet provided with lateral orifices 1410 and 1420 intended for the attachment of this flexible sheet inside a filing cabinet of the traditional type. In the center of this flexible sheet are arranged two pads 1520 and 1540 between which is left free a space constituted by a portion of flexible sheet. These two studs both have a substantially semi-disc shape and each of these studs is formed in one piece constituting in itself an underlying layer of the same thickness as that of a compact disc, as well as a tongue 1525, 1545, which extends away from the center of the support. In this embodiment of the invention, each stud 1520, 1540 is extended by a projection 1527, 1547 which extends perpendicularly to the flexible sheet away from it. These two projections 1527 and 1547 are long enough to be close to each other by a user, for example between the thumb and the index finger of the latter. The support of Figures 31 and 32 is advantageously placed on a compact disc as follows. The compact disc is placed on the flexible sheet so that the projections or edges 1527, 1547 protrude from the central orifice of the disc, the tongues 1525 and 1545 of the retaining member 1500 being at this first stage not yet introduced in the hole, then the user pinches between the thumb and the index finger the edges 1527 and 1547 in approach to one another, which produces an approximation25 of the pads 1520 and 1540, the ends of the tabs 1525 and 1545 thus being brought closer by a distance less than the extent of the orifice of the disc. Under the effect of the pinching of the organ, the disc then crosses the tongues in the direction of the flexible sheet against which it comes to rest by the whole of its surface. The user can then release the edges 3027, 1547 so that the studs 1520 and 1540 resume their initial arrangement by elastic return of the flexible sheet, the tongues 1525 and 1545 coming to bear against the interior edges of the orifice of the disc, holding it pressed against the flexible sheet. The device of FIG. 33 consists of two main elements: a first of these two elements is a flexible sheet 2100 extending over practically the entire surface of the device and having a substantially rectangular shape. The flexible sheet 2100 is provided on two of its edges with passages for filing rings so that this flexible sheet can be used as the page of a conventional filing filing cabinet.10 A second main element of the support of FIG. 33 is a plate 2200 of external dimensions similar to those of the flexible sheet 2100 and having a central opening 2250 of circular shape. This open plate 2200 is bonded to the flexible sheet 2100. The opening 2250 of this plate is a circular opening having the same dimensions as a compact disc. The plate 2200 further has, at the periphery of this central circular opening, two extension tabs 2252 and 2254 extending towards the inside of the opening 2250. These two tabs 2252 and 2254 are arranged diametrically opposite and s extend from the inner edge of the opening 2250 of the circle over a length substantially equal to one tenth of the dimer of the opening 2250. These tabs are of substantially rectangular shape. The plate 2200 is preferably produced in a plastic sheet having a rigidity significantly higher than that of the flexible sheet, for example a flexible plastic sheet of approximately 1 mm thick. Thus, this part 2200 gives the support of FIG. 33 an overall rigidity close to that of a compact disc. The device of FIG. 33 therefore has a generally square shape of which a whole circumferential border is covered by the plate 2200, so that this plate constitutes a frame for the central circular window 2250. This support is implemented in the following way: a compact disc is stored in such a support by slightly raising the two tabs 2252 and 2254 away from the flexible sheet 2100. These tabs being slightly raised, the compact disc is slid in a direction of movement perpendicular to the direction in which5 s' extend these tabs, between the tabs and the flexible sheet. The sliding is continued until the disc comes to take position in the opening 2250 under the tabs 2252 and 2254. The plate 2200 having a thickness substantially equal to that of the compact disc, the compact disc therefore fits in the same plane as this and in no way overflows from the plate 2200 at the edges of the central opening 2250 thereof. Thus, once the compact disc in the opening 2250, the tabs 2252 and 2254 prevent this disc from moving perpendicular to the plane of the support and keep the disc in the plane of the frame 2200, the outer edges of this disc being against 15 the inner edges of the central opening 2250, so that the disc can in no way slide on the flexible sheet parallel to the plane of the support. The disc is therefore held in the opening by elastic return of the two tabs. According to an advantageous arrangement of the invention, each of the two

  tabs has a corner 2253, 2255 raised away from the flexible sheet in the form of a permanent fold.

  Thanks to these folded corners, it is not at all necessary to raise the tongues 2252, 2254 by hand when placing a disc, a simple sliding of the disc in friction against the support, perpendicular to the tongues 2252, 2254 , brings the edges of the disc into contact with its raised pleats and thus induces a sliding of the tabs against the edges of the disc in raising thereof, the tabs moving apart to let the disc slide between them and the flexible sheet. The fact that the plate 2200 has a higher rigidity than that of the flexible sheet 2100 makes it possible to obtain a support providing a certain

  protection against accidental bending of a compact disc.

  Furthermore, the support provided with the compact disc has a constant thickness over its entire surface so that such a support can be used in large numbers within a storage filing cabinet or any other storage device in which the supports provided of their compact discs are stacked on top of each other. Because the flexible sheet has a very thin thickness, storage in a stack does not present any additional bulk compared to a stack of discs directly on top of each other.10 To extract a compact disc from such a support, it suffices to the user to grasp the support by a border of it, that is to say by an area of the support where the compact disc is not present, and to exert a pressure of the fingers in a central area of the sheet flexible 2100 on the side opposite the compact disc. By such manipulation, the support consisting of the plate 2200 and the sheet 2100 is deformed in bending, its edges moving away from the compact disc, so that at least one edge of the compact disc is distant from the support. The user can then grasp this edge of the disc which is released from the support and slide the disc out of the support.20 Depending on whether the edge of the support moved by the user corresponds to an edge carrying a tongue or not, the optional tongue of this edge

  will flex more or less against the edge of the disc. If the user grasps the support by an edge in the vicinity of a tongue, the tongue may flex against the edge of the compact disc until it completely crosses this border, the disc then being completely released from its support.

  Conversely, if the edge bent by the user does not have any tabs, the user will advantageously grasp the sliding disc disengaging from the support, perpendicular to the axis of the tabs. It is thus understood that the tongues can be chosen to be rigid enough to produce a particularly firm hold on the disc, the lateral clearance to the tongues then being the

  clearance recommended by the user.

  It should be mentioned that the raised corners 2253, 2255 of the tongue are arranged on the same side with a diameter of the opening 2250 by the centers of the diametrically opposed tongues 2252 and 2254.5 Thus, the pair of corners each arranged on a tongue constitutes with the flexible sheet a guide funnel for the disc driven transversely to the tongues. FIG. 34 shows two compact disc supports conforming to that of FIG. 33, arranged one against the other. As can be seen in this figure, the compact discs can, thanks to such a support, be stored either back to front or front to front. Thus, in FIG. 34, the two discs are arranged so that their faces

  are opposite. In other words, the faces of the two supports which carry the tongues are brought into contact one against the other. As can be seen in this figure, the supports then come to bear against one another over their entire surface.

  Advantageously, the raised corners of the tongues of two successive supports stored in a filing cabinet are placed on different sides of a diameter passing through the centers of the two tongues of a support. Thus, the raised corners of a first support do not come into contact with the raised corners of the support which is combined with it, but these corners come into contact with the tongue of the combined support in an area opposite the one carrying the corner. noted. It is therefore understood that thanks to the deformability of the flexible bottom sheet, the user can effortlessly push this flexible sheet and deform it perpendicular to the mean plane of the support to exert sufficient pressure on the disc to bend the tongues against the edges of the disc so that it is no longer nested over its entire surface against the support. In FIG. 33, it can be seen that the support is provided on two sides perpendicular to each other, with passages for the rings of a filing cabinet, so that a set of supports such as that of FIG. 33 is

  advantageously stored in a filing cabinet so that the supports are arranged with their tongues sometimes aligned in a first direction and sometimes in a second direction perpendicular to the first. 5 The supports are advantageously placed with their tongues along these two axes in an alternative manner.

  Thus, a thickness effect due to a possible stacking of the tongues in excess thickness does not take place in such a stack.

  The support of FIG. 36 differs from that of FIGS. 33 and 34 in that the tongues 2252 and 2254 each have a cavity forming a receptacle for a folded corner of a tongue of a support applied face to face against this first support. More specifically, the tongues 2252 and 2254 of the support of FIG. 36 each have a folded guide corner and on a side opposite this corner with respect to a diameter of the support passing through the tongues, an extension of the tongue forming a loop inscribed in thickness

  of the tongue at the center of which loop is formed a window 2257, 2258.

  This window is therefore arranged on a tongue symmetrically to the guide fold of the tongue relative to an axis of the support passing through each of the two tongues thereof. Thus, when two supports conforming to that of FIG. 36 are placed face to face as in FIG. 34, that is to say tongue against tongue, in other words upper face of a compact disc against upper face of compact disc , the guide folds 2253, 2255 of a tongue are received in the corresponding opening 2257, 2258 of the tongue of the opposite support. More specifically, two tongues belonging to two opposite supports and coming into contact with each other overlap each other, a first tongue having its fold inserted into the opening of the second tongue and this second tongue also having its fold

  introduced into the opening of the first tab.

  Thanks to such an arrangement, a fold of a tongue does not bear against any surface during storage in stacks, so that the

  deformation of the fold away from the support is in no way attenuated or accentuated by a possible permanent support of this fold against another surface.

  In Figure 37, there is shown a device according to a variant of the invention consisting of a disc produced in a flexible sheet provided with

  its center of a member for fixing a disc by introduction into the central orifice 10 of a disc.

  The device of Figure 37 has the distinction that the flexible sheet has a greatly reduced diameter compared to that of a disc

  compact. Furthermore, the flexible sheet forms a disc 3000 having on an opposite face to that carrying the member 700, an adhesive surface. This flexible sheet disc 15 300 is intended to be glued to a flat surface such as a page of a notebook or a magazine.

  This disc 3000, once glued to a flexible surface such as a page of a notebook, forms with this page an overall support for a compact disc having an extent greater than that of this disc. Such a disc with adhesive face is therefore particularly advantageous for fixing a compact disc, in particular in the case of magazines offering a compact disc as a gift, and more generally for the distribution of compact discs by mail. Figure 38 corresponds to a cross section of the central member 700 of the device of Figure 37. As can be seen in this figure, the device 700 is constituted as described above, by a plate

  flexible upper 750 bonded to a boss 3100 formed in the flexible sheet 3000 and this boss being of cylindrical shape with planar upper face having a thickness slightly greater than that of a compact disc.

  FIG. 39 shows an alternative embodiment of the invention in which a rigid plastic base case is used, corresponding in its general geometry to the bottom of a compact disc case of the common type. Thus, this housing 4000 has a frame 4200 forming a circular opening in its center for the reception of a compact disc, this rigid frame being extended at the bottom of its central opening by

  a flat wall 4300 offset from the upper surface of the frame 4200 by a depth substantially equal to the thickness of a compact disc.

  The bottom wall 4300 of this compact disc receptacle is provided at its center with a substantially circular orifice 4400 with a diameter equal to about a quarter of the diameter of the receptacle. The 4400 hole is therefore larger than that of a central hole of a compact disc. The orifice 4400 is extended into two diametrically opposite zones with respect to this orifice of cavities 4320 and 4340 produced in the bottom wall. Each of these cavities itself has a deeper bottom wall than the wall 4300. The support of FIG. 39 also has a member intended to be introduced into the orifice of a compact disc. This body is made up,

  as can be seen in FIG. 40, of an underlying layer 5710 on which a flexible plate 5720 is placed.

  More specifically, the layer 5710 is molded with a flexible strip 5730 having a length sufficient to pass through the orifice 4400 and to protrude by its two ends 5712 and 5714 within the two

cavities 4320 and 4340.

  Thus, the support of FIG. 39 presents within its central orifice 4400 a flexible part made up of two languages 5712 and 5714 each extending a cylindrical central element 5710 and 5720 intended for

  get into a compact disc. In a preferred embodiment of the invention, the central element forming the layer 5710 and the lateral tongues 5712 and 5714 thereof is a rubber element.

  It is thus understood that the layer 5710 and the plate 5720 covering it can thus be moved through the orifice 4400 in a direction of movement perpendicular to the mean plane 4000. When the user places a compact disc in the receptacle 4300, the orifice of this 5 disc is in abutment against the plate 5720. The user can then apply pressure both to the disc to keep it in its receptacle and on the back of the rubber element forming the tongues 5712, 5714 and the layer 5710, to move the plate 5720 and the layer 5710 through the hole in the compact disc. Of course, those skilled in the art will be able to combine the arrangement in accordance with this embodiment according to which a central orifice is disposed within a rigid support for compact disc, with any of the hooking devices of previously offered compact disc. Thus, it is possible to place in the central opening a flexible sheet provided at its center with a cutout forming a fastening member or more generally forming fastening tabs for the edges of the opening of a compact disk. Similarly, the single element forming both the tongues 5712, 5714 and the layer 5710 can also be replaced by a strip of flexible material forming the two languages,

  on which is fixed a second part forming the layer 5710.

  In the embodiment presented in Figures 39 and 40, the plate 5720 is fixed to the element 5710/5712/5714 by a central rivet passing through these two parts. Languages 5712 and 5714 are fixed in the cavities

  4320 and 4340 also by riveting.

  A support conforming to that of FIGS. 39 and 40 combines the advantage of a rigid case with regard to the protection of the disc against accidental impact and the advantage of a bottom member placed on a flexible part, allowing movement of this perpendicular to the plane of the support due to the ease and effectiveness of such attachment. There is shown in Figures 41 and 42 a variant also corresponding to the embodiment of Figures 39 and 40 in which the plate upper 5720 forms a rectangle with a rounded end fixed on a rubber band and in which variant two rigid reinforcements are arranged near the ends of the plate 5720, between the latter and the rubber band. 5 In this example, a band of rubber 5712/5714 forms in the central part a bulge 5718 whose upper face is flat and is intended to receive the plate 5720. On either side of this bulge 5718, on sides diametrically opposite this bulge, are arranged reinforcements 5732 and 5734 intended to stiffen the rubber band between the plate 5720 and the band 5712/5714. The plate 5720 has an elongated shape the ends of which protrude from the central bulge 5718, come into contact with an upper part of a reinforcement 5732, 5734, and extend beyond these reinforcements by forming catching tongues. Each of the ends considered is fixed to this reinforcement before protruding from it so that the plate 5720 is held rigidly at the level of these reinforcements. Reinforcements have the effect of promoting

  a firmer elastic return of the end tabs formed by the plate 5720, away from the bottom wall of the receptacle 4300, which allows effective crossing by flexion, of the flexible plate 5720 relative to the edges of the orifice a compact disc.

  In FIG. 43, a support is presented consisting of a flexible sheet in the center of which an opening 6000 of square shape is made and

  slightly larger than the central hole of a compact disc. This square opening 6000 is crossed by an elastic band 25 7000 of width less than that of the square and fixed by its ends on opposite edges of the square opening.

  In the central part of this strip 7000 and on a face thereof opposite the flexible sheet is bonded a rectangular piece 8000 intended

  to cross by bending the edges of a central orifice of a compact disc.

  This part 8000 forms a rectangle similar to those presented in the previous embodiments.

  The rectangle 8000 extends along its length in a direction perpendicular to the direction in which the strip 7000 extends, so that the rectangle 8000 protrudes by its ends on either side of the longitudinal edges of the strip 7000. These ends protruding from the strip 7000 thus form hooking tongues for the orifice of a disc to be maintained. The member formed by this rectangle 8000 is easily introduced into the central orifice of a compact disc by placing the compact disc against this rectangle 8000 and by pressing with a finger on the elastic band 10 7000 through the 6000 square opening to produce by elastic deformation of the strip 7000 a displacement of the member 8000 in separation from the sheet forming the support. The rectangle 8000 then takes place on a face of the compact disc opposite the flexible sheet. This embodiment is particularly suitable for producing a compact disc support in which the flexible sheet is replaced by a rigid sheet. Indeed, if the elastic band 7000 has sufficient elasticity, the movement of the member 8000 can be authorized by the sole deformation of the elastic band 7000. In FIG. 44a, a band 7000 of elastic material is shown in cross section. comprising in the central part a deformation forming a bump 7200 of planar upper surface and suitable for receiving

  on this face a rectangular plate such as plate 8000 of FIG. 43.

  Figure 44b shows that this boss or protrusion 7200 has

  advantageously a rectangular shape when viewed from above, the corners of which are truncated.

  Thanks to such an elastic band, the rectangle 8000 is arranged in a plane offset from the mean plane of the support by a distance which is close to the thickness of a compact disc. Thus, the plate 8000, in its position for fixing a compact disc, retains a substantially flat shape and produces a particularly effective attachment of this disc.

  compact, without play between the disc and the plate 8000.

  The support of FIGS. 45 and 46 has a support sheet of flexible material in which bosses 8500 are formed uniformly distributed angularly around a central member 700, these bosses5 forming, by the flexibility of the support sheet which constitutes them, damping buffers. protecting the compact disc from accidental impact. Thus, these bosses 8500 extend on a face opposite to that carrying the central member 700 so that these bosses are intended to come to bear by their ends against a disc carried by another support of a stack of such supports . Thus, a compact disc is, by a first face, supported on an upper flat surface of such a support and, by an upper surface, supported on bosses 8500 of flexible material in zones uniformly distributed angularly on this compact disc .15 Thus, a shock or deformation of general direction perpendicular to the plane of the compact disc results in a deformation of the bosses 8500 and produces no shock on a compact disc placed between two such supports. Figures 47 and 48 show two supports 9200 and 9400 according to the invention, connected together by a portion of flexible plastic sheet 9500, so that these two supports can be folded against each other face to face, the sheet 9500 forming a folding hinge between the two supports 9200 and 9400. The two supports and the hinge sheet 9500 therefore form an overall sheet, the supports 25 9200 and 9400 each carrying their respective member 700 on the same side of the assembly sheet so that in a storage position, the compact discs face each other by their upper face. As can be seen in FIG. 48, the hinge sheet 9500 advantageously has sufficient elasticity to maintain a spacing between the two supports 9200 and 9400 such that a shock applied to one of the two supports results in a deformation of this hinge 9500

* which thus absorbs such a shock.

  Of course, the invention is not limited to supports for compact discs of traditional size but extends to supports for

  discs having any type of dimensions, such as for example miniaturized discs or large discs.

  In a variant of the invention with a central member for hooking the orifice of a disc, edges of flexible plastic material are advantageously fixed on the edges of the flexible bottom sheet, which, once folded over a disc attached to the support, sandwich the disc 10 between them and the backsheet. Such flaps improve the attachment of the disc and protect the disc against impacts or scratches on its upper face. The support of Figure 49 has a flexible sheet of extent less than that of a compact disc and provided in its center with a member 700 intended to pass through the orifice of a compact disc. The flexible sheet of this support has on the face of the flexible sheet carrying the member 700 an element projecting from this face and having the property of being able to be compressed against this face. This element, referenced 9800 in FIG. 49,

  is a ring of compressible plastic foam bonded to the flexible sheet and surrounding the member 700.

  Thus, as can be seen in FIG. 50, there exists between an upper face of this ring 9800 and a plate 720 of the member 700.

  distance slightly less than the thickness of a compact disc. Thus, when the member 700 is put in place through the orifice of a compact disc, a lower face of this disc comes to bear against the foam 9800, compressing it slightly against the flexible sheet.

  More specifically, the upper plate 720 exerts on the edges of the orifice of the disc a support of its lateral tongues against the latter capable of producing a slight compression of the 9800 foam. Such foam 30 provides damping between the disc and the sheet. flexible bottom, so that an accidental support on the disc or on the support causes compression of the foam rather than a sudden abutment of the disc on any other part of the support. In FIGS. 51 and 52, a support for a compact disc is shown in which a flexible sheet 9900 forms, in the vicinity of a central member 700, projections in the form of bosses produced in this flexible sheet and forming a projection on the face of the sheet which also carries the member 700. Such projections 9920 have sufficient deformability to produce damping of a compact disc between the latter and a bottom wall 9900 of the support. 10 More precisely, the projections 9920 of the device in FIGS. 51 and 52 extend obliquely to the plane of the wall 9900 at the bottom of this support. In other words, the 9920 projections have a form

  of a thermowell pointing obliquely towards the central member 700, approaching the latter. These bosses each deform by an overall bending against the bottom wall 9900 of this support.

  These projections in the form of bosses 9920 have a width measured in an orthoradial direction relative to the center of the support which is sufficient to provide a bearing surface of a compact disc on each of these protuberances of the same order of magnitude as the diameter20 of the opening of a compact disc. The projections 9920 thus produce a same function as the foam 9800 of the device of FIGS. 49 and 50, it is at

  say that they produce an elastic return of the compact disc against the lower edges of a plate 720 of the member 700 and provide damping against possible impacts on the disc or on the support 25 of this disc.

  Of course, the arrangements described above, consisting of adopting a compressible member between the disc and a bottom wall, can advantageously be adopted within a device whose bottom wall is a rigid wall. is not limited to the case where a flexible bottom sheet is made of plastic. Thus, such a flexible sheet can be a sheet of paper or a sheet of fabric as in the case of the device in FIG. 53. The support of this figure has a flexible bottom sheet on a central part of which is fixed a member. 700, and a circumferential part 9970 sewn all around this central part 9950. When the member 700 is introduced into the orifice of a compact disc, the flexible bottom sheet formed at the same time by the part 9950 in fabric and by the plastic part 9970 is deformed more particularly at the level of the central part 9950 in fabric, while the circumferential part remains little deformed. The adoption of a deformable fabric sheet has the advantage that no wrinkling of the fabric can occur.

  flexible sheet due to the deformation thereof. A sheet of fabric can also be adopted for its robustness properties or for its aesthetic properties.
