Abstract
An articulated spine for books with changeable sheets, consisting of two pieces in a double right angle that carries the lower edges of the vertical faces that overlap, when the spine is closed, articulated by a longitudinal hinge. The hooks constituting the rings project alternately from one and another part of the spine, their tips locking in the holes of the upper vertical side of the opposite part. One of the pieces of the spine is solid, while the other is cantilevered. (Machine-translation by Google Translate, not legally binding)
