FR2835088A1 - CD jewel case with external indicator includes slide element moving when disc is inserted to provide clear indication via window - Google Patents

Abstract

The CD box has a window (33) formed in the upper surface of the wide edge (33). A slide extends into the housing (31) and is moved to and fro by the action of inserting or removing the disc. An external indicator shows whether there is a disc in the box, when closed. The CD box comprises a double bottom (3) nested within the base, and has an opening (36) in the edge of the housing (31). A window (33) is formed in the upper surface of the wide edge (33). A slide extends into the housing (31) for operation by the action of putting a disc (5) in place within the box. The slide (4) has a tongue (43) in the form of a very open dihedral shape, connected by a hinge (44). The tongue has a tab (433) which is elastically placed against the lower branch (41) of the slide, at least during the final movement of closing the joint (44). A surface (421) forming part of the tongue assembly moves beneath the window (33), so that its position gives a clear indication of the presence of absence of a disc within the casing.

Description

<Desc / Clms Page number 1>

 The present invention relates to a CD disc box comprising a bottom, a cover and a double bottom nested in the bottom.

This double bottom has a housing for the disc, surrounded by a raised track, a wide edge raised on the side of the articulation of the cover, an opening in the edge of the double bottom housing, on the side located towards the wide edge, a window in the upper surface of the wide edge, a slider-shaped indicator coming into the housing, to be activated by placing the disc in its housing and appear in the window to indicate the presence of the disc in the box. The slide is a piece with an L-shaped section, the lower branch of which carries a very open dihedral-shaped tongue, formed by a first flap connected by a hinge, at an angle; a second flap naturally protrudes from the cavity of the box to be on the closing path of the lid and, in the absence of a disc, cooperate with the inner surface of the lid to be pushed towards the interior of the cavity and pull the slide in the retracted position or be subjected to the action of the disc placed in the housing to press against the inclined part of the raised edge and push the slide back into its indicative position.

 We already know such a CD disc box.

 The present invention aims to develop such a box and to improve the functioning of the slide and to develop the visibility of its display.

 To this end, the invention relates to a box of the type defined above, characterized in that the dihedral-shaped tongue of the slide carries a tab which comes into resilient abutment against the lower branch of the slide, at least during the end of the closing movement of the joint.

 The elastic support of the tab of the tongue makes it possible to accumulate energy at the moment when the dihedral-shaped tongue of the slide is depressed by the installation of a disc or by the closing of the box. This elastic support relieves the hinge connecting the tongue to the remaining part of the slide and above all makes it possible to produce a hinge without having to give it, by its structure or its material, a particular elasticity.

 So when the disc is released, or when the box is opened, the elastic energy stored in the combination of the tab and the tongue, automatically opens the angle made by the tongue with the lower branch of the slide and lifts the LAN-

<Desc / Clms Page number 2>

 watch elastically, in the standby position either for placing a disc or for closing the box.

 Advantageously, the tab is released from the surface of the tongue. This tab can in particular be cut out of manufacture in the surface of the tongue and be shaped to come out of the surface of the tongue and create the elastic support when the tongue is crushed by the disc placed in the housing or the closure of the cover.

 This embodiment is particularly simple and does not require any particular mold or manufacturing process except for the simple means releasing the tab from the tongue.

 Advantageously, the lower branch of the slide has a stop against which the edge of the tab bears, at least during the end of the closing movement of the tongue, against the lower branch of the slide. This support reinforces the elastic action of the tab by causing the elastic deformation of the tab during closing and thus accentuating the elastic energy accumulated in the tab for the opening of the tongue when the disc is removed or opening the box.

 Advantageously, the stop is constituted by a housing produced in the lower branch of the slide.

 This housing embodiment also prevents the slide from having an excess thickness so that the disc can be positioned quite naturally in its double bottom housing.

 Advantageously for manufacturing, the tab is pre-stressed by hot deformation to disengage from the surface of the first flap of the tongue. This permanent deformation particularly gives the tab a shape allowing it to create an elastic support when the tongue is crushed against the lower branch of the slide.

 Advantageously in the disc box, the slide is provided with a display element connected by a hinge and formed by a piece in the form of an angle iron part of which is intended to be displayed in the window of the double bottom and the the other is behind the edge of the case when the slider is in the advanced position, indicating the presence of a disc in the box.

 Also advantageously, the slide is provided with a ledge coming into the window to appear at the edge of the window,

<Desc / Clms Page number 3>

 above the edge or back of the box when the slide is advanced by the presence of a disc in the box.

 It is particularly advantageous under these conditions that the slide is completed by a rim under the indicator surface and serving as a stop and indicator surface appearing behind the back of the box from which a fraction of the raised part of the inner label has been removed.

 * Figure 8A shows the shape of the double bottom before the removal of the parts corresponding to the window and the passage, * Figure 8B shows the shape of the double bottom after removal of the parts corresponding to the window and the passage of the slide.

 According to FIG. 1, the invention relates to a CD disc box composed of a bottom 1 to which a cover 2 is connected by means of an articulation 11 with pivots and housings. A double bottom 3 nested in the bottom. The double bottom 3 receives the disc 5 and, for this, it comprises a disc housing 31 surrounded by a raised surface occupying substantially the four corners of the double bottom. This raised range ends with a wide edge 33, on the side of the joint 11 of the cover. This edge 33 is provided with an opening 36 opening at least into the housing 31 of the double bottom 3.

Finally, the top of the wide edge 33 has a window 35.
The opening 36 and the window 35 are located substantially at the level of the axis of symmetry of the box.

 A slide-shaped indicator 4 is placed in a movable manner in the housing 31 to be actuated as shown in FIG. 1, by the front edge 51 of the disc 5 when the disc is introduced into the housing. This movement of introduction of the disc 5 produces, on the one hand, the tilting of the slide 4 and on the other hand, its sliding so as to reveal a part of the slide 4 in the window 35 and signal the presence of the disc once the lid closed.

 The slide 4 is a part having an overall L-shaped section with a lower branch 41 corresponding to the horizontal branch of the L-shape and a rising branch 42 corresponding to the vertical branch of the L-shape. The rising branch 42 carries an indicator surface 421 which, depending on the position of the slide 4, appears in the window 35 or is retracted under the wide edge. This indicator surface 421 includes indications or can receive a label.

 By its end opposite to that by which it is connected to the vertical branch 42, lower branch 41 is connected to a tongue 43 by an articulation 44. This articulation is produced by the material in which the slide is formed.

 This tongue 43 consists of two flaps 431,432 forming between them a very open, relatively rigid dihedral. This tongue

<Desc / Clms Page number 5>

 serves to receive the end 51 of the disc 5 to be actuated as described above.

 The dihedral-shaped tongue 43 carries a tab 433 which comes into the angle formed between the lower branch 41 of the slide 4 and the tongue 43 to constitute an elastic support between the lower branch 41 and the tongue. This elastic support occurs either at least towards the end of the reclosing movement of the angle between the tongue 43 and the lower branch 41 of the slide, when a disc is placed in the housing 31, or at the time of closing. of the cover when the case is empty.

 The elastic support produced by the tongue 433 is created by the inherent elasticity of the tongue due to its shape and / or to the material. This tongue is advantageously made of the same material as the whole of the slide and in a single part with it.

 Advantageously, the tab 433 is cut from the first flap 431. Then this tab 433 is deformed when hot to disengage from the plane of the flap 431 while having the possibility, when the tongue 43 is crushed against the branch interior 41, at least partially retract in the cutout 434.

 The elastic support of the tab 433 can result from its simple deformation but also it can be supplemented by the abutment of the front edge 4331 of the tab 433 against a stop, for example the edge of a housing 411 produced in the branch lower 41. This housing can be constituted by a cutout.

 The front edge 412 of this cutout 411 is positioned to force the tab 433 to deform elastically under the effect of the disc 5 in order to store elastic energy.

 FIG. 2 shows a witness in the form of a slide 4A according to FIG. 1, with a slight variant concerning the structure of the second branch 42A and of the indicator surface 421A. The branch 42A reaches the edge of the indicator surface 421A opposite the side of the hinge 44A. This form of slide 4A can have advantages of simplicity of embodiment since the space between the walls 42A, the lower branch 41A and the tongue 43A is more clear.

 This perspective view shows the cutout 434A and the tab 433A.

 This view does not show a housing or stop similar to the housing 411 or its edge 412 forming the stop for the free edge of

<Desc / Clms Page number 6>

 tab 434A. These means can be provided in this embodiment.

 Figures 3A, 3B, 3C schematically show the three stages of movement of a slider 4 according to the invention, independently of the practical embodiments of the slider. The movement shown is that of closing the slide under the action of a disc in place or closing the cover (neither the disc nor the cover are shown in these figures). The opening movement is done in the reverse order, passing from the position of FIG. 3C to that of FIG. 3A.

 Finally, FIGS. 3A-3C do not show the displacement of the slide.

 In FIG. 3A, the slide is in the raised position or natural position, the angle a between the lower flap 431 and the lower branch 41 being the natural angle originating either from molding or from shaping after molding.

 The tab 433 is released from the plane of the flap 431. In this position, it possibly bears against the lower branch 41.

 The lower branch 41 has a stop 412. This stop 412 has the same reference as the edge 412 of the housing 411 in FIG. 1. This stop may be the edge of a housing not shown or a deformation produced in the branch 41. The role of this stop is stopped the sliding movement of the edge 4331 of the tab 433 to cause its elastic deformation at the end of closure. However, depending on the material in which the slide and also the tab 433 are made, the sole elasticity of deformation of the tab 433 may be sufficient to accumulate energy for the opening movement of the tongue 43.

 When one acts on the tongue 4 to close the angle a either by applying a disc against the tongue 4 to place the disc not shown in its housing or with the cover, when the empty box is closed, the parts of move as shown in FIG. 3B: the tab 433 moves either by bending or being deformed according to undulations, to absorb the reduction in space available since it comes against the stop 410. In the meantime, to pass from the position from FIG. 3A to that of FIG. 3B, the lower edge of the tab has traveled the distance to the stop 410.

 The compression and deformation movement of the tongue 433 then continues until the final position for fitting the

<Desc / Clms Page number 7>

 disc or cover closure; the tab 433 is retracted either in a cut made in the flap 431 or in a cut made in the lower branch 41 or partly in each of these two cutouts.

 The energy accumulated in the lug 433 constitutes a restoring force which lifts the tongue 4 when the empty box is opened or the disc is extracted, which favors the coming or the return of the tongue 4 in the initial position shown in Figure 3A.

 The opening and lifting movement of the tongue takes place substantially in the reverse order of the order described above, that is to say that one passes from the position of FIG. 3C to that of Figure 3B then to that of Figure 3A. The elastic deformation of the tab 433 and the accumulated energy are particularly important for initiating the lifting movement of the tongue 4. This makes it possible to relieve or even replace the elasticity of the hinge 44 at the most important moment, at the start of the movement of relaxation or lifting of the tongue and this all the more since the elastic deformation of the tab creates an incomparably less fatigue than the fatigue that the hinge 44 can undergo if it is to ensure relaxation alone. This effect of the tab is based both on its elasticity and on the lever arm of the point of application of the elastic force relative to the hinge 44. This can be achieved without creating an elastic return effect, this which will increase its lifespan.

 Figures 4A, 4B show in section the two positions of the slide, at the beginning and at the end of the closing of the empty box.

 Figures 5A, 5B show the transformation of the slider shown separately for Figures 4A and 4B.

 FIG. 6A shows a variant of slide 4B formed like slide 4 of FIG. 1 for the parts not shown. The slide 4B comprises a display element 45B in the form of a square with two branches 451B, 452B; this element 45B is connected to the branch 42B of the slide 4B by an articulated connection 46B.

 The branch 451B is intended to come into the window 35 of the wide edge 33 of the double bottom 3 moreover provided with the opening 36 for the passage of the slide 4B. The branch 452B comes against the edge or back 10 of the housing 1 in the position of FIG. 6A; this position is that of the slide 4B when the housing contains a disc.

<Desc / Clms Page number 8>

 The edge 10 or back of the case 1 is made of transparent material as are generally the CD disc cases and, in this case, the inner label 6, usual for CD discs, has been removed at the edge 10, at least in its part corresponding to the slide or its branch 452B.

 When the slider 4B is slid to the right, the casing having been closed without disc inside, the display element 45B switches as it appears in FIG. 6B, so that the branch 451B no longer appears in the window 35 and the branch 452B moves away from the edge 10.

 The disappearance of the branch 452B behind the edge 10 will be particularly effective if this edge 10 is of a transparency attenuated by a satin effect not making it possible to read information clearly by the branch 452B which if it is directly behind the edge 10 and not at a certain distance as is the case in FIG. 6B.

 The tilting movement of the element 45B is ensured either by the abutment of the edge of its edge 451B against the edge 351 of the window 35 or by a prestressing of the articulation 46B or even by the combination of these two means.

 The element 45B is preferably made in one piece with the other parts of the slide 4B.

 FIGS. 7A, 7B show a variant of the double bottom 3C comprising the parts 37,38 closing the window 35 and the passage 36. These parts 37,38, produced at the same time as the double bottom 3C during molding, are delimited by molding precuts 371,381. The double bottom 3C is installed in the bottom 1 as shown in FIG. 7A and the parts 37, 38 can be detached by the user who will place a slide there, not shown. We then obtain the box already described, shown in Figure 7B.

 FIGS. 7A, 7B show a variant of slide 4C according to the invention. This slider is similar for its basic shape to the slider 4A of FIG. 2 but it is extended at the front by two returns or flanges; one of the flanges 223C is above the indicator surface 421C and the other flange 424C is below this indicator surface. This last edge can be higher or lower as shown by the dotted line.

<Desc / Clms Page number 9>

 In the advanced position (FIG. 7A), the rim 423C appears at the edge of the window 35 above the front edge 10 of the box 1. In this position, it signals the presence of a disc not shown in the box or in the bottom 3.

 This locating means can be very useful when the boxes are stacked perfectly and are classified upright in a row, the front edge 432C of the indicator surface 421C appears very clearly especially if it is distinguished from other parts of the box by its color. .

 Conversely, when the indicator surface 421C is set back since the box is empty, the distance from the front edge 423C of the indicator surface 421C relative to the edge of the window 35 does not make it possible to see the front edge which remains in the shade .

 This means thus makes it possible to easily detect the presence or absence of a disc in the box even when the boxes are arranged contiguously and the window 35 is not visible.

 The visibility of the display on the back 10 of the box can be increased if the back is released at the level of the slide 4C. in fact, the box is, in general, made of transparent plastic; its bottom as well as the back 10 are covered inside the box by a folded label 6, the part 61 of which covers the inside bottom of the box and the raised part 62 covers the document 10; this label is blocked in the box by the double bottom 3.

 According to the invention, at least the fraction of the raised part 62 of the label which is opposite the slide 4C is removed (this is underlined in FIGS. 7A, 7B by the absence of hatching in the part 62 at this point ). So when the rim 424C comes against the back 10, it will appear behind it.

 The rim 424C which serves as a stop, can be extended downwards and thus present a very visible surface especially if it is light in color. This surface can also receive a glued label which will also be very visible in the position of FIG. 4A whereas it will not be or with difficulty only in the position of FIG. 7B which corresponds to the empty box.
