ABSTRACT:
A combination lock/deadbolt assembly connection technique is disclosed for connecting the bolt of the combination lock to the deadbolt of the deadbolt assembly to provide a lost motion connection while at the same time to retain the ability to position a magnetic anti-attack interlock within the bolt of the combination lock. A connecting shaft is disposed between the bolt and the deadbolt and a spring bias force introduced between the two bolts. The shaft may be attached rigidly at one end to either the lock bolt or deadbolt. The opposite end is loosely attached by retaining rings or retaining rings to accommodate the movement of the loosely attached bolt with respect to the shaft thereby providing a lost motion connection. A compression spring is disposed intermediate to the lock bolt and the deadbolt to provide a separating or extending force. The connection constitutes a lost motion connection to permit either the withdrawal of the deadbolt without withdrawal of the lock bolt or extension of the lock bolt without requiring extension of the deadbolt.
