  • Patent number: 4530136
    Abstract: A selectively lockable latch to be used, for example, in fastening two furniture parts or the like in temporary alignment comprises a bolt member, a strike box unit and a lock rod. The bolt member includes a projecting nose and a channel which bisects the nose to define a slideway for the lock rod and to divide the nose into a pair of flexible arms. A snap-latch arrangement acts latchably between the bolt member and the strike box unit and includes selectively interengagable cam surface elements. The lock rod is slidably received in the nose channel to be selectively disposed between the flexible nose arms in one position to prevent covergence of the arms and to lock the bolt member in the strike box unit, the lock rod being selectively withdrawable from between the flexible nose arms into a second longitudinal position whereby to permit convergence of the arms and release of the bolt member from the strike box unit.
