ABSTRACT:
Door lock and lock assemblies are useful, for example, in vehicle cabs. Latch and lock assemblies of known structures which can be unlocked from inside the cab while remaining locked from outside the cab require complex and bulky linkage assemblies. The subject door latch and lock assembly includes pivotal outer and inner actuator. The pivotal movement of the outer actuator simultaneously pivots the inner actuator to open a catch mechanism. Pivot movement of the inner actuator can be independent of the outer actuator. A locking lever can be pivoted to a locked position to prevent pivotal movement of the outer actuator. Pivotal movement of the inner actuator is not prevented by the locking lever. Thus, the disclosed door latch and lock assembly can be opened from inside the cab while remaining locked from outside the cab without requiring complex and bulky linkage assemblies.
