    Abstract: A book container employs metal rods interleaved among the pages of a book or passed through the spine of a book to hold the book within hinged, semi-rigid covers which are spring-biased to a closed position. The container depends subjacently from a shelf and parallel to the edge of the shelf by means of a doublypivoting bracket. The bracket allows the container to be revolved onto the shelf and rotated to be positioned for normal viewing of the book. The pivot shaft includes a transverse radial pin riding an annular cam, the weight of the container when depending from the bracket causing the pin to traverse the cam surface and rotate the container and return it parallel to the shelf edge.

    Abstract translation: 书本容器采用在书的页面之间插入的金属棒,或者通过书的书脊,将书放在铰接的半刚性盖中,弹簧偏置到关闭位置。 容器通过双重旋转的支架从搁板上取下并平行于搁板的边缘。 支架允许容器旋转到搁板上并旋转以定位以正常观看书。 枢轴包括一个环形凸轮的横向径向销,当从托架上离开时,容器的重量使销钉横过凸轮表面,并使容器旋转并使其平行于货架边缘。
