 This application claims the benefit of U.S. Provisional Application No. 60/417,455 filed Oct. 10, 2002, incorporated herein by reference.
 a. Field of Invention
 This invention pertains to a device for displaying DVDs, CDs, VCR tapes and other content media. More particularly, the invention pertains to a cabinet-type display device that has one or more shelves rotatable between an open position in which access is allowed to the contents of the device and a closed position in which the contents of the cabinet are unaccessible.
 b. Description of the Prior Art
 Cabinet type display devices are well known in the art for simultaneously storing and exhibiting various articles, such as jewelry, food stuff, compact discs, books, etc. The shelves are mounted in a housing, or other similar support structure. In some instances, the devices are placed in a retail establishment near sales personnel and are constantly monitored. Hence, these display devices do not require any locks or other security protection.
 In other instances, the display devices are placed in high traffic areas where at certain times no monitoring personnel is available. Therefore these display devices are provided with locks to prevent theft, pilferage and other unauthorized and removal of articles from the display devices. Some examples of display devices with locks are found in U.S. Pat. Nos. 4,463,856; 4,850,658; and 5,797,487. However, the display devices used until now were unsightly, difficult to use or inconvenient.
 Accordingly, there is a need for a convenient and practical display device that can be used to either display devices or store them safely in a protective housing.
 Briefly, in accordance with this invention, a display case for storing and showing articles includes a housing, a case adapted to hold several articles, the case being mounted in said housing, and being rotatable between an open position in which the articles from the case are visible and accessible, and a closed position in which the articles are inside the housing and not accessible. A lock is also provided on the housing or the case and is adapted to prevent the case from moving when it is in the closed position. The lock may also be adapted to block the case from movement in the open position.
 In one aspect of the invention, the case is mount to rotate about its vertical axis with respect to the housing.
 A plurality of shelves are mounted on the case. The shelves may be arranged and constructed so that they can be removed therefrom if so desired. The shelves may be partitioned into two or more chambers sized to hold a stack of DVDs, CDs, or VCR tapes or other content media. The shelves may be made of a transparent plastic material so their contents are clearly visible.
 Preferably, each case has a back wall which is visible from the outside when the case is closed. This back wall, as well, as the lateral walls of the housing are used for decorative displays and/or advertisement.
 The movement of the case is limited to a predetermined angle of about 180°. This may be accomplished by providing a track in the housing bottom and a pin on the case riding in the track. The ends of the track form the movement limits.
 The housing can have various shapes including triangular, square, rectangular and have two, three or four cases. Each case can have up to six shelves and each shelve can be divided into several chambers holding stacks of media arranged vertically. For each chamber a spring clip is provided. The clip is arranged to push the stack toward the front of the chamber so that if one media is removed, for example a DVD, it is automatically replaced by another one,

 While in
 The shelves described above are particularly suited for DVDs and VCR tapes in sleeve type packaging because they have the same heights. Other types of packaging are also used. For example, a somewhat larger package for VCR tapes is available that is known as a clam shell package. For this type of package a slightly larger shelf can be made, which can be installed on the same case as the shelves described herein. Thus, several types of different media, including DVDs and VCR tapes having different sizes can be displayed using the same device.
 The device described herein has several advantages. Its cases can be easily rotated to the closed position in which the media are locked and cannot be stolen. The cases can be rotated very easily from one position to another without requiring special tools. No special doors or locks are required for the device. The device can be easily adapted to hold several types of different media without requiring any major tooling, since only the shelves need to be changed. The device can be manufactured using standard methods and techniques. Moreover, the device can be easily modified to accommodate not only various types of media, but it can be made larger or smaller, without any major tooling efforts. Fir example, a display device can be made with a single case
 The device can be constructed to form various shapes that are esthetically pleasing and has several highly visible surfaces, including sides
 While the invention has been described with reference to several particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles of the invention. Accordingly, the embodiments described in particular should be considered as exemplary, not limiting, with respect to the following claims.
