Lock mechanism for different lock types - has stepped spring loaded plungers aligned positively with lock pins

摘要

The locking mechanism can be used in lcoks for different purposes such as padlocks, mortice and motor vehicle door locks. The lock mechanism has no play between the guiding bores and lock pins and plungers no matter what their relative positions. This arrangement ensures that the key can be withdrawn only when the lock is positively locked and not at any angular position. Each plunger (8) is a stepped cylinder whose end with larger diameter faces the cylindrical pin (11) whose diameter is equal to the plunger larger end diameter. The axes of all pins and plungers coincide at a certain angular relative position of the housing opening.
