摘要： The device comprises a latching assembly enclosed within, and translatable relative to, a centercase housing; the housing is mounted on a chassis. The device is adapted for cooperative engagement with a locking cylinder, for actuating the latching assembly, and for operation of a thumbpiece lift, by an ancillary, external, trim linkage, for translating the latching assembly. The latching device has a master, locking cylinder cam or dowel, the latter having a removable screw, which (through a locking cylinder) either operates a night-latch cam plate, to translate the latching assembly or, upon removal of the screw, allows the cam or dowel to translate a tumbler which, in turn, frees a thumbpiece lift, for operation (then) of the latching assembly by the lift, instead of by the cam plate. Accordingly, with the drive screw in place, the external, operating trim linkage can not operate the device; it must be unlatched, externally, by a key in the locking cylinder. With the drive screw removed, the use of a key in the locking cylinder will not unlatch the device, rather, in this circumstance, key-operation of the locking cylinder will enable the external trim linkage to unlatch the device, and such key-operation (with the drive screw removed) will also disable the trim linkage operation of the device, selectively.
摘要翻译：该装置包括封闭组件，其相对于中心壳体封闭并且可相对于中心壳体壳体平移; 外壳安装在底盘上。该装置适于与锁定圆柱体协作接合，用于致动闩锁组件，以及用于通过辅助外部装饰连杆机构操作拇指引导件，用于平移闩锁组件。锁定装置具有主锁紧缸凸轮或销钉，后者具有可拆卸的螺钉，（通过锁紧缸）操作夜间闩锁凸轮板以平移闩锁组件，或者在拆卸螺钉时允许凸轮或定位销翻转一个翻转开关，而翻转开关反过来又释放了一个拇指提升器，用于由升降机而不是由凸轮板操作（然后）闩锁组件。因此，在驱动螺钉就位的情况下，外部操作装置联动装置不能操作; 必须通过锁定缸中的钥匙在外部解锁。拆卸驱动螺丝后，使用锁定缸中的钥匙不会使装置松开，而在这种情况下，锁紧缸的关键操作将使外部装饰联动装置能够松开装置，而这种按键操作（拆下驱动螺钉）也将有选择地禁用装置的调整联动操作。
