Abstract

De acuerdo con el invento, un dispositivo de encuadernar o unir hojas perfeccionado, para sujetar juntas una pluralidad de hojas que tengan aberturas previamente perforadas espaciadas entre sí, comprende un miembro de respaldo alargado que se extiende entre tales aberturas espaciadas entre sí; y unidos al miembro de respaldo en posiciones espaciadas entre sí, correspondientes al espaciamiento entre tales aberturas, una pluralidad de elementos de sujeción cada uno de los cuales comprende una parte de conexión para introducción en tales aberturas, y en el extremo de dicha parte de conexión alejado de dicho miembro de respaldo, medios de bloqueo movibles entre (1) una posición plegada en la cual el elemento de sujeción puede ser introducido en tal abertura, y (2) una posición expandida en la cual los medios de bloqueo son eficaces para hacer imposible la retirada de tales hojas de dicho elemento de sujeción. Esta estructura puede ser moldeada integralmente en material plástico. En una realización preferida, la estructura es sustancialmente de autobloqueo. También se describen realizaciones con un solo agujero, adecuadas como sustitutivas de los dispositivos de sujeción de cabeza de latón usuales.
