Description

Retention device for data carriers disk-shaped

Object of the invention

The present invention relates to a device retention that has been specially designed to hold disk-shaped elements, such as compact discs (CD), digital video discs (DVD) and the like, or any other device or disk-shaped support, which keeps those media or discs properly retained or secured well within a case, box or wrapper or in any other type of accommodation intended for that purpose.

The object of the invention is to achieve a safe and stable retention device that allows anchoring or clamping and removing the disc in the housing where it find said retention device, by a simple operation by the user.

Background of the invention

The retention devices for supports information or the like in disk form, according to the State of the Technique, and which are usually integrated or part of containers, boxes or other types of accommodation, included in the central part of its base an outgoing formation for the coupling by adjusting the disc through its central hole, normally using teeth or retention projections. The formation projection has compressible deformable areas, so that the disc can be released from its retention by exerting pressure on said outgoing or simply pulling the disc through its peripheral area. In addition they usually have circumferential projections at the base concentric form with the central outgoing formation to support in them the outer edge of the disk.

These types of mechanisms have different inconveniences, such as instability in the behavior of the rosette or central projection, or the need to make several combined movements for disc extraction, constituting poor ergonomics and low intuitive systems.

Another major drawback of this type of devices is that the maneuver for release or removal of the disc may cause deformation of the disc, flexing it radially, which can often reach damage it, or at least generate a fatigue effect on it.

From these systems, others emerged that they sought to facilitate the removal of the disk by means of a push button, as is the case of the mechanism proposed in U 9600471, which through A lever-like push button pushes the disc up. Without However, this device has numerous shortcomings such as the central clamp or the lever system itself that can scratch the area recorded among others. Another device similar to this one, and that it is also held by the central hole, with the problems that this supposes, previously indicated, is the one shown in EP 0671743.

Other documents, such as US 5690218, US 5533615, or some embodiments of US 5938020 also present of disc removal buttons, retention elements located on the periphery and cooperating with said button. Without However, none of them find lifting mechanisms of the disk when it has been released, which means that the disk it is not "offered" to the user in an appropriate manner. All these documents, also present the inconvenience of the scarce or null flexibility of its retention elements, which makes it force the disc during the clamping or anchoring operation.

In another embodiment, shown in US 6364107, you can see another system that has means of retention distributed around the periphery of the disk, as well as a release button However, when making the disk removal, this must be done by sliding said disk, with what it can touch in your recording area with the mentioned button.

Finally, EP 0886278 shows another possible solution, although in this case the disk rests only on two specific areas, which means an unstable restraint. In this case, in addition, the element that raises the disk once released, it is located in such a way that it hits the surface recorded of the same, being able to damage said area and causing the loss of the information contained in the disk.

Description of the invention

The retention device that the invention proposes to solve the problem fully satisfactorily previously exposed, ensuring a perfect fixation of the disc and an easy clamping and extraction operation by the user, who will need a single and simple movement to Perform each of these operations.

For this the retention device can go integrated into any type of case, box or housing, such as those normally used for, for example, compact discs (CD) or similar, in which the case consists of a lid and a base or bottom wall articulated by a central portion or spine, as a book, counting said retention device with a flange of a suitable size to support the outermost area of the disc, free of recording, and some retention teeth located on flexible elements located on the periphery, on the mentioned flange, so that the central hole is free, thus holding the disk on its perimeter.

The aforementioned flexible elements are composed with two tweezers and a button that swings over its end next to the disc, where the teeth of retention. On both sides of this button two pins are placed flexible, which are compressed when the disk is subject or anchored, and they push it up and raise it when the mentioned button is pressed to release it.

In this way, the anchoring of the disk is done from above, in the vertical direction. The pressure exerted on the disc causes the retention teeth to be removed and the disc rest on the support flange. Once the teeth have been passed, tweezers and button return to their original position and the disc is locked. The peripheral pressure of the clamps eliminates the possible disc vibrations in the case. There is also a ring central on the bottom wall of the case on which the area rests central disc, and that prevents it from flexing excessively during anchorage. Disk removal will be done by pressing the button located on the periphery, such that the teeth of retention are removed to release the disc and flexible pins they return to their resting position by raising the end of the disc to facilitate its extraction.

Another difference than the device that advocates presents with respect to others that for similar purposes are found in the state of the art, is that it can manufactured in one piece, which is an obvious advantage over them.

Preferred Embodiment of the Invention

In view of the figures outlined, you can be observed as the retention device that the invention proposed is likely to be incorporated into a case or box, as It can be commonly used to host a disk compact (CD) or similar, in which said case or box is formed by a cover (1) and a base or bottom wall (2), articulated with each other by a central portion or spine (3), that the confers a form or structure of "book".

In the aforementioned case, and more specifically about its base or bottom wall (2), said device is incorporated retention, which is formed by a lower circular flange (4) on which the disc (9) rests in all its circumference, and on its outermost zone, thus avoiding contact with the recorded area, and the central hole of the disc (9) being free.

In the area that defines the periphery of the disk (9), there are several flexible elements (5), formed by a couple of tweezers (5a) and a button (5b) that swings over its end next to the disc. Both flexible elements (5) count in your area upper located above the flange (4) with teeth retention (6), which in the case of tweezers and for this embodiment concrete are double and located at the ends of the clamp itself (5a) in each of them, and in the case of the button (5b), and for this specific embodiment, said retention tooth (6) is extends along the entire length of the mentioned button (5b) These retention teeth (6) are formed in their part lower by a flat horizontal surface that constitutes the disk retention means while on the top they are conformed by an inclined plane that allows the introduction of the disc when applying a small force on it vertical down, which will make the mentioned ones flex flexible elements (5), allowing the passage of the disc (9).

On both sides of the button (5b), they are two flexible pins (7) on whose free end supports the edge outside of the disc (9), pins that are compressed down when the disc is anchored or held, and that they are responsible for pushing up the disk (9) when performs the release of it.

The disk anchoring maneuver (9) is performed in the vertical direction, from above. The pressure exerted by the user on the disc (9), which rests on the teeth of retention (6) located on the flexible elements (5), makes these, both the clamps (5a) and the button (5b), swing towards back, causing said teeth (6) to be removed and the disc (9) reach the support flange (4). At this time, and once after the teeth (6), tweezers (5a) and button (5b) return to their original position and the disc is locked. Peripheral pressure of the tweezers (5a) eliminates the possible vibrations of the disc in the case.

To achieve even greater stability and clamping, it is expected that there is a small central ring (8) emerging from the bottom wall of the case (2), on which it will support the central crown of the disc without recording, thus avoiding that it flexes excessively during the clamping operation or anchorage.

When the disc (9) is anchored or held by the retention device, the pins (7) are they find tablets, thereby exerting a push towards above that is braked by the retaining teeth (6) of the flexible elements (5), thus leaving the disk (9) prisoner between both elements, and thus obtaining a restraint optimal between these elements.

Extraction or release is easily achieved by pressing the button (5b), which swings on its end closest to the disc (9), thereby removing the teeth (6) and releasing the disk (9), which will be pushed up by the pins (7), now free of compression. This operation It is clearly seen in Figure 6.

For this specific embodiment, the arrangement and number of retention and release elements shown in the figures, although the intended purpose with the present invention it can also be achieved with any other arrangement of the different fasteners and release located on the periphery of the device, as well as varying its number and relative position.
