Abstract

EN LA CABEZA SUPERIOR (11) DE UN MARTILLO MECANICO (10) SE COLOCAN CUÑAS TRANSVERSALMENTE DISPUESTAS (18) QUE SON ADAPTADAS PARA BLOQUEAR LA HERRAMIENTA DE TRABAJO (12), QUE SE DESPLAZA A LO LARGO DE UN EJE POR COOPERACION RESTRINGIDA CON RECESOS LATERALES (16) SOBRE LA HERRAMIENTA DE TRABAJO (12). CADA CUÑA (18) ESTA BLOQUEADA EN LA CABEZA SUPERIOR (11) POR UNA LLAVE (20), LA CUAL SE EXTIENDE A TRAVES DE LA CUÑA (18) HASTA UN AGUJERO TRANSVERSO (21). LA LLAVE (20) POSEE UN MECANISMO DE CIERRE LIBERABLE QUE CONSTA DE UN ELEMENTO DE BLOQUEO INCORPORADO A LA CABEZA SUPERIOR (11) Y QUE ESTA HECHO DE UN BLOQUE DE POLIURETANO (24). EL BLOQUE (24) ESTA PROVISTO DE UNA PERFORACION DE LADO A LADO (27), QUE TIENE PROPIEDADES DE RECUPERACION DE LA FORMA ORIGINAL DE UN MATERIAL ELASTICO. CUANDO, CON EL PROPOSITO DE CERRAR LA LLAVE (20), LA CUÑA (18) ES PRESIONADA A TRAVES DEL AGUJERO DEL BLOQUE (24), ESTE ULTIMO SE EXPANDE SOBRESALIENDO EN FORMA DE SURCO ANULAR (22) SOBRE LA LLAVE (20), CERRANDO ASI LA MISMA EN LA CABEZA SUPERIOR (11) Y ACTIVANDO SU FUNCION DE BLOQUEO DE LA CUÑA (18). EN EL CASO DE UTILIZAR DOS CUÑAS (18), UNA SOLA LLAVE (20) SERVIRA PARA BLOQUEAR LAS DOS CUÑAS (18), Y ESTA A SU VEZ SE CERRARA CON UN SOLO BLOQUE (24).
