Description

Anti-theft device for digital discs.

The present specification refers to, as its title indicates, to an anti-theft device for digital disks, of the type used in commercial establishments for prevent theft of digital discs of various types and contents, as audio CD, video CD, DVD, software, etc., characterized because it incorporates conventionally used boxes as digital disc case a hollow cylindrical internal protrusion that Locks the disc in the box holding rosette, preventing that the disc can be released from said rosette without opening the case.

It is commonly known the tremendous incidence that has had and still has in the commercial world the thefts of product in commercial establishments. This issue is particularly high in products such as digital discs, both audio (CD) and video (DVD) or data (software), and other similar products, which has a high economic cost and a relatively small size, being also very much wanted by the consumers.

To stop as much as possible the theft of these products, and try to eliminate the economic losses that leads to commercial establishments have come using many and varied anti-theft systems. One of the most Classic and effective are the closed cabinets containing the product, but they have the disadvantage that they do not allow customer manipulation, so they are not appropriate for large areas and other types of establishments with self service.

Another very effective and widely used system are the electronic protections by Radio Frequency, which they consist of placing in the disk box an element that can be detected in the detection arcs located at the outputs of the establishment. This protective element may consist of a adhesive label with a built-in coil, or in a "tag" or element mechanically fixed with the product. This system has the disadvantage that the protective element is going always attached to the box that protects the digital disk, because to the very nature of the digital disk can not adhere directly to disk It is quite common for people who wish to steal the disc proceed to unseal it, open the box and remove the digital disk, which, lacking any protection electronics cannot be detected, leaving the empty box along with its protection attached again in the lines of the establishment. Since the digital disk is the most valuable element, to friends They don't mind disregarding the box, especially when empty boxes can be purchased later so completely legal.

To try to prevent this type of theft, and as a complement to the aforementioned electronic protections, containers, boxes completely closed or only partially, which wrap the digital disk case itself to prevent it from being unsealed and opened are quite used. Examples of this type of anti-theft devices can be found in Patent 99901105 " Anti-theft case, particularly for compact discs, video cassettes, music cassettes and the like ", which describes a complete container box, or Patent 97943863 " Anti-theft case, small size , particularly for compact disc, musicasetes, videocassettes, and the like ", about a partial container box, or in Utility Model 8900196" Anti- theft for compac-disc cases ", which protects a box formed by two parts interlocked with a complementary electromagnetic system.

However, other people's friends have achieved in some cases ingeniously bypass these systems conventional protection, since they cut the seal of the box original of the digital disk by the lower connection slot, proceeding to flex or deform the box by pushing for its central part, where the rosette is located internally Hold the digital disk to the box. After several attempts it is frequent  that they can release the disk of their anchor rosette, falling by gravity to the lower end of the box, from where, forcing slightly the original disk case by compression by its ends so that the joint groove between the semi-parts of the box to then be able to slide the digital disk out of its case, and therefore out of both mechanical and electronic protection systems.

In order to try to protect against this new system of theft, some improvements have been devised, such as the one described in the Utility Model 200201968 " Box for compact discs with anti-theft means ", in which the anti-theft means consist of anti-theft pivots that perimetrically hold the disc, but which has the disadvantage that, by performing a force and a greater deformation than in the previous case, the disc can also be released. Also the Patent 200101904 " Anti-theft device for cases of versatile digital discs and the like " presents a modification of the disk retaining rosettes so as to prevent the retention tabs from bending with elastic flexion and freeing the disc from its retained position, but complicating enormously the mold for the manufacture of the boxes, at the same time that its effectiveness is quite relative, since as in the previous case the disks can be released simply by performing a greater force and deformation. These systems have the disadvantages that hinder theft to a greater or lesser extent, but still cannot avoid it.

To solve the problem in the news regarding the problem of theft of digital disks the anti-theft device for digital disks has been devised of the present invention, which consists of an internal protrusion hollow cylindrical, located in the part of the box used as digital disc case opposite the holding rosette and that Locks the displacement of the disk in the holding rosette towards its outside of the box, preventing the disk from being able to Release the rosette without first opening the box.

This protection device can be used in any of the box formats provided for discs digital of varied type and content, such as audio CD, CD video, DVD, software, etc., It is planned that this device protection is incorporated into the manufacturing process of the own box, usually in mold for thermoplastic injection, although it is also possible to have the protection device loose, in this case consisting of a low hollow cylinder height, with one of the sides closed and provided with a medium adhesive to be able to fix it in opposite position to the rosette in Conventional boxes not equipped with this device.

This anti-theft device for digital discs that is presented provides multiple advantages over those available in currently being the most important that eliminates the possibility of theft of the digital disk by the procedure of releasing it from its rosette and perform its gravity drop through the groove of the case, forced for this purpose by compression.

Another important advantage is that this important Improvement in anti-theft security is done in a simple and economic, with no impact on the final cost of product.

It is also remarkable that this device protection is fully compatible and complementary to conventionally used devices against theft, both Mechanical as electronic.

Also another added advantage is that, through the isolated protection device, it is possible to add this anti-theft device to any type of digital disk case, although it was not originally planned for it, being able to improve the anti-theft security of the boxes currently existing.

To better understand the purpose of this invention, in the annexed plane two embodiments have been represented preferential practices of an anti-theft device for discs digital
