Abstract
An improved security chain lock has the security chain assembly coupled integrally to the lock body and concealingly mounted with that lock body within a door to be secured. The security chain assembly housed within the same lock housing which houses the lock body is affectively concealed from view so as not to mar the interior decor of a room in which such a lock is employed to secure the door entry to that room. Latch means are provided which are mounted in the door frame in juxtaposition to the lock body so as to provide ready mating engagement of the security chain latch hook with the latch mounted in the door frame. An improved method of assembly of the latch means to the door frame, employing orthogonal reinforcing means which mate within the door frame itself, in combination with the innovative security chain lock, provide for an overall highly secure improvement in the state of the art of security chain locks.
