Definitions
- the invention relates to the technical sector of storage boxes, in particular for compact discs of the audio or video type.
- a compact disc has a recording area which appears on all of at least one of its faces, with the exception of its external periphery and of an area around the central opening presented by the disk.
- the other face of the disc cooperates with engagement and retaining means that has a support base intended to directly form a base to a housing or to be incorporated in a housing comprising a base on which a cover is articulated.
- This support base which generally forms a flat surface, has different types of arrangements capable of ensuring the engagement and retention of the compact disc and sometimes its ejection.
- the invention relates to solutions of the type of those where the retention of the disc relative to the support base is effected by means cooperating with the central opening of the disc.
- these means consist of a plurality of lugs arranged circularly and directly overflowing from the support base.
- These lugs are elastically deformable and have, at their free end, arrangements, by example in the form of a boss, capable of ensuring the retention of the disc after engagement through its central opening.
- the elements forming the push button generally have lugs capable of ensuring the retention of the disc after engagement through its central opening. To remove the disc, press the push button to release its central opening. In certain solutions covered by the aforementioned patents, pressing the push button requests means allowing the disc to be ejected.
- 96/14636 discloses a holding and ejection system in the form of two radial arms formed in overflow from the support base with capacity for elastic deformation. The free end of each arm is arranged to constitute the push button engaged through the opening disc center.
- the external peripheral edge of the disc is supported on a circular rim formed in overflow from the support base. Given this circular support at the periphery of the disc, it results, under the effect of engagement of the push button through the central opening, a bending of the disc which, in this case, is used to facilitate its ejection .
- This solution is not satisfactory since the disc is subjected, at the time of its ejection, to bending forces capable of providing internal tensions detrimental to the disc.
- the object of the invention is to remedy these drawbacks in a simple, safe, effective and rational manner.
- the problem which the invention proposes to solve is to be able to ensure the retention and ejection of the disc relative to the base, without subjecting the disc to any bending force, while allowing its manual gripping, after having acted on the retaining means which cooperate with the central opening of the disc, in a simple and effective manner, without requiring any particular arrangements at the level of the support base.
- the means for engaging and retaining the disc are formed by overflowing a circular central zone presented by the base;
- the area has arrangements capable of allowing, when a digital pressing force is exerted on said means, to retract them in part only to cause, in a concomitant manner, the controlled tilting of the disc corresponding to its partial release by relative to the base in order to enter it manually at its cleared part.
- the disc rocks in a housing on one of its sides, while its other side is offset from the face of the base for its grip.
- the base can have, on the side of the disc tilting, a support profile capable of retaining said disc in the tilted position.
- the support profile is constituted by a substantially elliptical rim cooperating with part of the circular edge of the disc.
- the substantially elliptical rim is connected to the base by a slot allowing the partial engagement and the stop of the corresponding circular edge of the disc.
- the arrangements of the central area are constituted by at least a support and stiffening means suitably positioned with respect to cutouts, in combination with the means for engaging and retaining the disc, said central zone appearing in elevation of the base, creating a circular recess to be elastically deformed.
- the means for engaging and retaining the disc consist of a push button and tabs, said button is connected to a central part hollowed out of the raised area, by tabs between which appear said tabs formed from cutouts of said raised area to be elastically deformable; at least one of the tongues is made rigid by the support means suitably positioned with respect to the cutouts.
- the support or stiffening means or means consist of ribs positioned in relation to at least one tongue and / or part of the push button.
- the support rib and stiffening of the tab considered is formed in overflow in the hollowed part of the raised central zone to be located in the same plane support than that of the base, said rib being oriented along the median axis of symmetry of the cutouts from which said tongue is formed.
- the support and stiffening rib is formed in overflow of the hollowed part of the raised central zone to be located in the same support plane as that of the base, said rib being located opposite and near one of the connecting tabs of said button, while a cutout, formed in the thickness of the raised area , partially surrounds said rib.
- the different ribs are diametrically opposite.
- the push button has three connecting tabs regularly distributed over a circumference being offset by 120 °, each of the tabs being arranged according to the bisector of the angle delimited by two legs to be regularly distributed over a circumference being offset by 120 °.
- FIG. 1 is a plan view of a compact disc support base equipped with the holding and ejection device according to the features of the invention
- - Figure 2 is a sectional view taken along line 2-2 of Figure 1 in the position of holding the disc and before digital pressing on the push button;
- FIG. 3 is a sectional view taken along line 3-3 of Figure 1, after pressing the push button showing the controlled tilting of the disc for gripping relative to the base;
- Figure 4 is a view similar to Figure 1 showing another embodiment of the device, in particular for retaining the disc and its controlled tilting;
- FIG. 5 is a cross-sectional view taken along line 5-5 of Figure 4 in the disc retaining position
- - Figure 6 is a cross-sectional view taken along line 6-6 of Figure 4 showing the tilting of the controlled disc for its gripping and its support;
- FIG. 7 is a partial perspective view showing the means for engaging and retaining the disc in a simplified embodiment of the base
- the device for holding and ejecting the compact disc is formed from a support base (1) which directly constitutes one of the compartments of a storage box of any known type and appropriate. Obviously, as indicated, the support base (1) can constitute an independent element.
- the support base (1) has engagement and retaining means able to cooperate with the central hole (Dl) presented by the compact disc (D).
- These disc engagement and retention means are formed by overflowing a central zone (la) which appears in elevation of the base (1) - to be elastically deformed under a pressure force exerted on the engagement means and retaining, through the central opening of the disc.
- This zone (la) has a circular geometric shape and delimits a flat bearing surface (lai) connected to the base as such, by an inclined circular rim (la2) delimiting an internal recess (la3) allowing the aforementioned elastic deformation.
- the means for engaging and retaining the disc consist of a central button (lb) in combination with elastically deformable tongues (le), (ld) and (le).
- the button (lb) and the set of tabs (le), (ld) and (le) are capable of being engaged through the central hole (Dl) of the compact disc (D).

- Each of the tabs (le), (ld) and (le) is arranged according to the bisector of the angle limited by two connecting lugs to be regularly distributed over a circumference while also being offset by 120 °.
- the raised central zone (la) has arrangements capable of allowing, when an effort digital support is exerted on the push button (lb), to retract only part of said button and tabs under the surface of the disc in order to cause, concomitantly, the controlled tilting of said disc (D) corresponding to its partial clearance from the base (1).
- these arrangements consist of at least one, but generally support and stiffening ribs (lh) and (li) suitably positioned with respect to cutouts in combination with the push button (lb), in particular its connecting tabs (lbl),
- these ribs (lh) and (li) have the function of making rigid, that is to say no longer allowing deformation by elasticity, of some of the tongues and / or of a part of the push button (lb).
- the rib (lh) is intended to stiffen the retaining tab (le).
- the rib (lh) is formed along the median axis of the rib (le) from the hole (lf) in the raised central area.
- the rib (lh) is formed overhanging the hollowed out part (la3) of the raised central zone to be located in the same support plane as that of the base (1). More particularly, the rib (lh) is oriented along the median axis of symmetry of the cutouts (lg) from which the tongue (le) is formed.
