Abstract
EL INVENTO SE REFIERE A UN DISPOSITIVO DE ENLACE DESTINADO A HACER INDEFORMABLE EL ANGULO FORMADO POR DOS ELEMENTOS ENLAZADOS POR UN PIVOTE, DEL TIPO QUE CONSTA DE UNA BARRA DE ENLACE (16) ARTICULADA A UN EXTREMO SOBRE UNO DE LOS ELEMENTOS (10). DICHA BARRA DE ENLACE ESTA PROVISTA, EN SU EXTREMO LIBRE, DE UNA MUESCA TRANSVERSAL (20) QUE PERMITE EL ENGANCHE DE LA BARRA EN UNA PIEZA MACHO (22) QUE SOBRESALE SOBRE EL OTRO ELEMENTO (12). EN LA BARRA DE ENLACE ESTA MONTADA UNA CORREDERA (24) QUE PRESENTA EN UN DE SUS EXTREMOS UNA ENTALLADURA QUE, CUANDO LA CORREDERA SE DESPLAZA HACIA EL EXTREMO LIBRE DE LA BARRA, SE UNE A DICHA PIEZA MACHO, IMPIDIENDO DE ESTE MODO QUE SE LEVANTE LA BARRA. EL INVENTO SE APLICA EN PARTICULAR EN ESCALAS DOBLES.
