INDEPENDENT INTERNAL AND EXTERNAL DOOR LATCH ACTUATION MECHANISMS
A latch system includes an actuation module (52) having first and second actuation mechanisms (110; 90). The first actuation mechanism (110) includes a first handle (104) coupled to a locking rod (92) having an end slot (106) and an oppositely disposed rod insert (94). The second actuation mechanism (90) includes at least one second handle (76a, 76b), a conversion block (80) and an outer rod (68) coupled together. The outer rod (68) has an open end (96) and a slot (100). At least one latch module (54a, 54b, 54c) has a retractable latch. A control cable (56a, 56b, 56c) connects the conversion block (80) and the latch module (54a, 54b, 54c) such that rotation of the conversion block (80) in a first direction retracts the latch. A lock (58) is operably engagable with the end slot (106) to selectively allow and prevent rotation of the inner rod. Selective rotation of the locking rod (92) in the first direction rotates the conversion block (80). Rotation of the outer rod (68) in the first direction rotates the conversion block (80) without rotating the locking rod (92).
