Puerta basculante perfeccionada, caracterizada esencialmente porque el movimiento de la misma está facilitado por un sistema d e muelles que crean un equilibrio d e peso al abrir cerrar la puerta propiamente dicha, porque la citada puerta al abrir s e desliza por unas guías que s e levantan hasta la parte superior del marco de la puerta, y además porque los muelles están siempre paralelos al referido marco, separados e ligeramente del mismo en las fases de abertura o cierre de la citada puerta.
