  • Patent number: 4155457
    Abstract: A device is disclosed for the display of jewelry articles such as earrings and the like, such device including a frame to which parallel overlying article supports are attached. The device further includes a slide having a plurality of flanges adapted in turn to overlie the article supports in such a fashion that when the slide is in a lower position, the space between the adjacent flanges and article supports is such that the articles cannot be removed from the latter. The slide is subsequently movable to a second upper position wherein such space is sufficient for the removal of the articles. An alarm responsive to the slide movement between such lower and upper positions serves to indicate any unauthorized attempt to remove an article.
