Abstract (en)
Mechanical digital lock operable through a series of mechanical operations actuated by the depression of digital keys (3), which comprises a combination of essential mechanisms M including the plurality of keys (3), digital selectors, identifiers, locking means and automatic resets. Activation of the correct keys operates a release mechanism which allows rotation of a rod (9) to retract a bolt (7). The lock cannot be opened unless the predetermined digits are sequentially depressed. Once the lock is opened, it is automatically reset. A change of combination of digitals can easily be manually effected without any tool. With its novel structure, it is highly reliable.
