Description

DEVICE FOR SAVING COMPACT DISCS TECHNICAL CONSIDERATIONS The present specifications refer to an invention consisting of a device for holding compact discs, in a case for storing compact discs or in a file-type box (similar to those used to store video cassettes) that has such a device incorporated, as well as to a method of manufacturing said apparatuses, cases and boxes.

"Compact disk", in the context of the present specifications, refers not only to the normal disk of 120 mm in diameter that is read by means of lasers, such as those commonly sold with recordings of music, software, computer data , etc., but also to several similar discs of different sizes such as those that are or are intended for video recordings, movies, interactive games and other kinds of information or data.

BACKGROUND - DESIGNS As a general rule, when these discs are not used, they are kept in transparent polystyrene cases that have a piece or tray in which the disc is fixed, a piece with seven or eight projecting teeth arranged in a circular shape, like a rose window, so that they can hook and unhook the central opening of the compact disc.

The teeth of the rosette extend vertically from the tray and bend outward, so that they can grip a compact disc, and. towards its end, they bend inwards forming a projecting rim on which the central perforation of the compact disc is placed and pressed by hand.

It has long been recognized that this kind of device for storing compact discs does not give very satisfactory results, since both hands are needed to disengage the disc and separate it from the rosette; consequently, there are many people who do not press the center of the rosette, but use only one hand to grasp the compact disc by the edge and forcefully pull it from the rosette, so that the disc is bent and sometimes the engraved face is scratched against the teeth, which in the end end up deformed and even broken.

The damage suffered by the disc when it is bent and scratched can have very serious consequences especially when the disc has recorded programs or computer data in compressed form, as it usually happens today.

Numerous inventions attempt to rectify these problems and offer a disc tray device with a more reliable and effective release mechanism.

EPA-0356539, for example, discloses an apparatus in which the rosette is provided with a central driving part with crank vanes arranged in such a way that when the driving part is pressed the crank vanes push the disc upwards unhooking it from the teeth of subject EPA-0429195 advocates the application of an elastic force to disengage the disc from the central flange. PCT WO-A-93/01598 for its part advocates a release button arranged so as to act on the inner ends of the teeth of the rosette and a spring that the stored disk remains without tension and when the button is pressed causes that the disk rises US-A-5,251,750 proposes to join the inner ends of all the teeth by means of a "living" hinge created by virtue of a smaller thickness of the molded material, at the same time linking the button to four crank expulsion arms arranged in such a way that when the button is pressed the ejection arms push the compact disc away from the rosette.

DE-A-3425579 discloses a cassette for storing discs equipped with a rod that serves to hold the disc. The rod comprises tongues joined by means of a pressure plate in such a way that the diameter of the rod contracts when a load is applied to the pressure plate. The tongues of the rod are provided with retaining cams which engage the central opening of the disk. The disc is held by means of the rod that keeps it in contact with a raised support at the base of the cassette.

Said prior designs have a comparatively complex construction and therefore difficult and expensive to manufacture, and / or do not work with the desired efficiency or reliability.

One of the objects of the invention described here is to introduce improvements to the previous designs with an apparatus intended to hold a compact disc - aptc * for its incorporation into the tray of a compact disc case and in a file-type case - with a mechanism reliable and easy to use, which serves to disengage the compact disc stored in it. Other possible advantages of the invention are apparent from the following description.

DISCLOSURE OF THE INVENTION According to a first aspect of the invention, this consists of an apparatus intended to hold a compact disc provided with a central hole, said apparatus consisting of the following elements: a base; means for holding the disc that extend from the base and serve to engage and disengage the disc hole, means consisting of at least two arms fixed in cantilever to the base, oriented radially towards the center and provided with bending elasticity , forming together the inner ends of the arms a button-shaped element provided with a flange or shoulder that acts on the upper face of a disc attached to the apparatus by the fastening means, in such a way that to disengage the disc, it is It is necessary to press the button-shaped element to fold the arms and consequently to deform at least the central part of the compact disc, until the approximation of the inner ends of the arms due to the aforementioned folding of the arms is sufficient for the flange of the arms disengages from the upper face of the compact disc.

This construction has the advantage that the inner ends of the adjacent arms forming the button-shaped element are connected to each other by an integrated living hinge; the inner ends of the arms can also be connected to each other by a second button-shaped element acting on the inner ends of each arm.

On the other hand, the button-shaped element has the advantage that its surface generally has a concave shape in such a way that the possibility of an unforeseen contact acting on the inner end of one of the arms and the disc is reduced. Disengage accordingly.

Expelling means by elastic force are preferred to disengage the disk from the clamping means after the flange or shoulder stops acting on the upper face of the disk.

Moreover, the expulsion means by elastic force are preferably arranged in such a way that the disc rests on them without the disc coming into contact with the base when it is turned on by the fastening means, so that during its manipulation and storage the disc is supported on the ejection means by elastic force which consequently cushions the disc against possible impacts and shocks.

Indeed, according to a second aspect of the invention, this consists of an apparatus intended to hold a compact disc provided with a central hole, the apparatus comprising: a base, means for holding the disc that extend from the base and serve to engage and disengage the central opening of the disc, and ejection means by elastic force arranged in such a way as to push the compact disc out of the action of the fastening means when the release button is depressed, the ejection means being arranged by elastic force in such a way as to cushion the disc against the base when the disc is turned on by the fastening means. The expulsion means by elastic force consequently protect the disc against possible impacts and shocks during transport or handling.

For its part, the expulsion means by elastic force preferably comprise a plurality of more cantilever arms fixed to the base and oriented towards the center; or the expulsion means by elastic force may comprise one or more pieces of a compressible material that is compressed when a disc is engaged by the fastening means and extends causing the disc to disengage from the fastening means when the disc is depressed. release button.

According to a third aspect of the invention, this consists of an apparatus intended to hold a compact disc provided with a central opening, the apparatus consisting of: a base, means for holding the disc that extend from the base and serve to hook and disengaging the central opening of the disc, and support means for the disc located in the base that serve to support the disc at points outside the central opening area, so that the center of the disc can be deformed towards the base and, after the disengagement of the central opening of the disc, it can resume its normal, not deformed state, moving the center of the disc out of the action of the fastening means.

In the exposed configuration, the elastic deformation of the disc is used to facilitate the necessary displacement of the center of the disc and for the integral disc to move away from the base when the release button is depressed.

The disk support means are preferably provided with a plurality of points that surround the perimeter of the disk in such a way that when the fastening means have a disk on, it rests without coming into contact with the disk support means. .

It should be understood that the device, according to the present specifications, can integrate a tray that is inserted in a normal case for compact discs or in a file-type box, the tray or box being built in both cases - with the obvious except for a second button and / or ejection means by the elastic force of a compressible material - integral one-piece plastic, molded in a single operation, made for example of polypropylene or a copolymer of butadiene and styrene.

Accordingly, according to a fourth aspect of the invention, this consists of a file-type box constructed of a single molded piece which is characterized by being provided with means that serve to engage and disengage the central opening of a compact disc. Preferably said means are integrally constructed on one of the inner sides of the box and comprise an apparatus of the type described further back.

The other features of the invention are apparent from the following description and from the dependent claims.

IDEAL FORM OF CARRYING OUT THE INVENTION The file-type box shown in FIGS. 1 to 8 comprises a lid 11, a base 12 and a spine 13 connected to the lid 11 and to the base 12 by means of living hinges 14.

The lid 1 1 is provided on its inner side with molded devices 1 1 A spring, clip type, used to hold brochures or printed material that are included with the disc, and the inner face of the base 12 has a partially annular ledge 12A molded which is responsible for protecting the disc against leaflets, etc. that are loose in the box and at the same time serves as a trim framing the disc that contains the box. When the box is closed, the male elements IB of a closing clip located in the lid 11 fit into the female elements 12B located in the corresponding part of the base 12.

Molded integrally in the same base 12 is the apparatus intended to hold the compact disc (Figures 6, 7 and 8 include a disc), said apparatus comprising: the base 12 of the box; two radial arms oriented towards the center fixed in cantilever to base 12, provided with flexural elasticity and joined together by their inner ends, said inner ends forming a button-shaped element that serves to hook the disc indicated in general with the number 16 and described in more detail below with * remissions to figures 6 and 7; and four arms 17 oriented towards the center and provided with bending elasticity that serve to eject the disc, said arms being likewise fixed in cantilever to the base 12 as explained in more detail later with references to figure 8.

The box, made of polypropylene or a copolymer of butadiene and styrene, is injection molded, the base having 12 openings or cuts under the arms 15 and arms 17 (as shown in Figure 4) to facilitate the preparation of the entire box in one piece by a single molding operation; subsequently (as is the case in normal file-type boxes) a transparent plastic sheet 18 (see Figures 3 and 4) can be welded to the outer face of the box such that a pocket is formed between the plastic sheet and the box in which a dust jacket or paper strip can be inserted with informative data (not shown) to identify the contents of the box and cover the cuts of the base 12 of the box that could otherwise be aesthetically demeaning.

With respect to figures 6 and 7, in which the two radial arms 15 oriented towards the center are fixed in cantilever to the base 12, the base 12 can, if desired, be reinforced by enlarging the thickness 19 of the molding. The button-shaped element holding the disc indicated generally with the number 16 is molded in such a way as to form two substantially semicircular segments 20, joined together by an integral living hinge 21 such that if any of the segments is depressed the other will also have to move.

Although it is preferable that the segments 20 together form a button-shaped element 16, it is understood that in certain cases the segments 20 may be joined together by mechanical means, for example by means of a second button-shaped element (FIG. not illustrated).

On the other hand, the upper face of the button-shaped element 16 can consist of a surface of generally concave shape as indicated by dotted line 22, thereby decreasing the possibility of accidental contact with the shaped element. of button 16 acts against the inner ends of either of the arms 15.

Each semicircular segment 20 is preferably molded so as to have a flange 23 which acts on the disc and protrudes from a cut or recess 24 in its corresponding arm 15 in such a way that the ridges 23 can be molded in the single operation of molding.

To attach a compact disk 25 to the apparatus, it is placed in such a way that the central opening rests on the segments 20. The pressure is then applied to the disk towards the base 12. in such a way that the edge of the central opening slide on the fluted edge 20A of each segment 20. The applied vertical pressure of the shape exposed by the disc 25 to the segments 20 has the effect that the arms 15 flexes approaching the base 12 in such a way that the segments 20 approach each other until they pass through the central opening and the arms 15 can resume their non-flexed position. or substantially not flexed.

As can be seen in Figure 6, the segments 20 adopt an appropriate shape to act on the opening of a compact disc as shown at 25, since the flanges 23 firmly hold the disc 25 acting on the surface thereof. It is located on the edge of the central opening. To separate the disc from the device, pressure is applied, in the direction indicated by the arrow "P" in figure 7, to fold the segments 20 and consequently the arms 15 against the base 12, in such a way that the flange or shoulder 23 stops acting on the The upper face of the disc 25 remains unhooked from the segments 20. Because both segments 20 are joined by mechanical means, it is evident that although the pressure is not applied in the center of the button-shaped element 16, the segments will not leave of falling down, disengaging the central opening of the disc 25.

It is also evident that in order for the lips 23 to disengage from the disc 25 without damaging the edge of the central opening thereof, at least the center of the disc 25 must be able to move towards the base 12 when pressure is applied in the P direction. The elastic bending ejection arms 17 must also be able to allow the centering of the disc 25 towards the base 12 when the disc 25 is to be turned on to the apparatus.

Disengagement of the disc 25 from the segments 20 is effected by means of the four arms 17 for ejection of the disc by elastic flexure, oriented towards the center, which act on the disc 25 causing it to move away from the base 12 when the rims 23 leave to act on the disc. Then the disk 25 rises to facilitate its separation from the apparatus. The arms 15 can also contribute to raising the disc 25 when it summarizes its normal, non-deformed position, once pressure is no longer exerted in the P direction.

As can be seen in figure 8, the disc ejection arms 17, which in figure 2 are on the axis 8-8, are fixed to the base 12 in cantilever at a distance * 'x "from the center - at least 20 mm and preferably 30 mm - oriented radially, forming an angle "A" with the base 12 within a band of 10 to 40 degrees and preferably 20 to 30 degrees in its normal state, not flexed, so that when the disc is turned on by the segments 20. the arms 17 are bent by tracing an arc of only 5 to 20 degrees, preferably 10 to 15 degrees, in such a way that they do not exert a very great effort and therefore can function reliably during for a long time, each arm 17 is molded in such a way that the supporting end 26 adopts an appropriate shape for supporting the inner annular area of the disc 25 which has no recorded information.

Preferably, the ends of the arms 17 are arranged in such a way that they come into contact with an area of the disc 25 located approximately 5 to 10 mm away from the edge of the central opening of the disc.

As is easy to understand, the disc 25 can be detached from the apparatus with complete confidence and ease simply by pressing the button-shaped element 16 whereby the disc 25 is unhooked from it and the elastic flexing arms 17 act on the disc 25 raising it a few millimeters in such a way that it can be grasped easily by its perimeter and separated from the apparatus. The button-shaped element 16 is made in such a way that when the finger exerts pressure on any part thereof, the rim 23 stops acting on the disc 25 separating from it.

The ejection arms 17 are bent when a disc 25 is stored in the apparatus in such a way that while the compact disc is attached to the apparatus, the disc, by virtue of the elastic force, bears against the underside of the rim 23 and remains separated from the base 12 by the action of the elastic bending arms 17. The disc 25 is thus protected against impact during handling and transport. The ejection means by elastic energy 17 also serve as support for the disc 25 when a pressure P is applied to the button-shaped element 16. limiting the degree of bending of the disc while the ridges 23 are disengaged from the disc.

Although the apparatus illustrated in the drawings has four elastic bending arms 17, the apparatus only has to carry at least two and preferably three arms 17 at least to provide a stable support and effective ejection to a disk 15, the apparatus being able to include more of four arms 17 although due to the lack of space, the number of arms 17 that the base 12 can accommodate without weakening and / or adversely affecting the effectiveness of the arms 17 is reduced.

On the other hand, the elastic bending arms 17 can be omitted and the means for ejecting the disc by elastic force consist of one or several pieces of some compressible material, for example foam, located in a position such as that which collects the circle drawn with a dotted line 17 A in Figure 2 in such a way as to act between the base 12 and the disc 25.

As can also be seen in figure 8, the two elastic bending arms 15 that engage the disk, and which in figure 2 appear on the axis 6-6. they are fixed in cantilever to the base 12 at a distance "and" from the center, radially oriented, distance which is preferably at least 10 mm and more preferably at least 15 mm, forming an angle "B" within a band 50 to 30 degrees, preferably between 10 and 20, with the base 12 when they are in their normal, non-deformed state, such that if they engage a disk 25 as shown in Figure 6, the arms 15 are folded by tracing a arch of 10 degrees or less, preferably 5 degrees or less, in such a way that does not diminish the effectiveness of the apparatus due to its repeated use over a very long period.

As shown in FIG. 8, the arms 15, the segments 20 included, have an extension substantially equal to the distance "y" since the distance separating the segments 20 is typically less than 5 mm. The arms have a width preferably of at least 5 mm, and more preferably of 10 to 15 mm and a thickness of 1 to 2 mm.

It is understood that the arms 15 can take other forms, e.g. ex. they can be inclined towards the base 12 to which they are fixed in cantilever and then extended by drawing a line substantially parallel to the base 12 where they terminate in the segments 20.

Although the described apparatus has two arms 15. In a variant (not illustrated) the apparatus can be provided with three arms with these ends, each of which has its inner end molded in a segment form in such a way that together they integrate a button-shaped element that serves to turn on the disk; notwithstanding the fact that the apparatus can be provided with more than three arms for these purposes, it is considered that due to the lack of space it could not carry four or more arms with the necessary robustness to withstand a frequent use and on the other hand it would be more difficult to achieve an effective mechanical union of the ends of each of said arms.

The apparatus, according to the specifications of the invention, can also, as shown in Figure 9, be incorporated into a tray that fits into a normal case. In Figure 9, the case comprises a normal box 27 with a normal cover 28 articulated at 29 in the known manner. Inside the box 27 is inserted the apparatus for holding the compact disk, in the form of a tray, generally illustrated under the number 30, tray comprising a flange 30A in part annular (which adopts a slightly different shape to that of Figure 1 ), a base 31, two elastic bending arms 31 fixed in cantilever to the base 31, oriented towards the center and joined together by their inner ends, inner ends that together form a button 33 to engage the disc in the same way than the button-shaped element 16 described above with reference to the previous figures. On the other hand, the tray 30 that collects figure 9 also includes four expulsion arms 34 of elastic flexion oriented towards the center equal to the arms 17 that figure 1 gathers. Therefore, it should be understood that the apparatus illustrated in the figure 9 has the same operating system and functions in the same way as illustrated in the previous figures and does not need, as a result, to be described again.

In another different construction, the expulsion means by elastic force can be omitted, using instead the capacity of elastic deformation of the disk to obtain the necessary displacement so that the means of attachment of the disc hook it and so that, when removing the disc , this is separated from the fastening means once they have been disengaged from the central opening of the disc. This construction will be described with references to Figure 10.

The apparatus illustrated in Figure 10 is provided with elastic bending arms 15 and a button-shaped element 16, etc., like the other constructions described further back, so it will not be described again. The disc supporting means 35, however, consist of the base 12 so that the disc rests when pressure P is applied to the button-shaped element 16 as described further back, resting the disc at points remote from the opening of the disk 25, preferably towards the perimeter of the disk 25 as shown in FIG. 10.

Preferably, the support means 35 of the disc are arranged so that the disc 25 does not into contact with the base 35 when the arms 15 are in their substantially normal, undistorted position, while the apparatus bears a disc 25 as it collects. Figure 10 When pressure is applied to the button-shaped element 16 in the direction of the arrow P, the disk 25 moves towards the base 12 until its perimeter is seated in the support 35. The pressure that is still exerted on the element in shape The button then presses the center of the disk against the base 12 so that the center of the disk is bent downwards until the shoulders 23 are disengaged from the disk 25 and the latter is free to resume its normal non-deformed state, thereby the center of the disk moves away from the base 12 and the disk 25 rises, facilitating its separation from the apparatus. As in the constructions described further back, the arms 15 contribute to raising the disk 25 once the button-shaped element 16 has passed through the central opening to be located under the disk and has been no longer exerted pressure P.

Although the flexing of a act disc is generally avoided (as in the constructions described and illustrated in Figures 1 to 9), if the perimeter of the disc has support at least three points, six preferably, the deformation is distributed in the entire disc in such a way that it folds in the same way, substantially. than a diaphragm.

As indicated above in the description of Figures 1 to 10, at least the base 12 or 31, the ejection arms 17 or 34 (if applicable) and the radial arms 15 or 32 can be manufactured as an integral piece of molded plastic and preferably the integral tray-holder and the file-type box are manufactured in a single molding operation.

Also, as can be seen from the foregoing, the apparatus for attaching a act disk can be incorporated in a file-type box, preferably molded integrally to one of the internal faces thereof as shown in the illustration, or in another form of box or container to which it is integrated by virtue of integral molding or as tray or insert piece.
