ABSTRACT:
Disclosed herein is an improved door latching device which is generally composed of two sections which are hingedly connected to each other, one section including a latch plate and a first control mechanism, the first control mechanism being capable of causing the latch plate to assume a non-latched condition, a half-latched condition or a full-latched condition, the other section including a second control mechanism and a third control mechanism, the second control mechanism being capable of transmitting the movement of the door inside handle to the first control mechanism, the third control mechanism being capable of disabling the second control mechanism from transmitting the movement from the door inside handle to the first control mechanism. With the hinge portion, the two sections are openable to assume a substantially flat configuration thereby to facilitate the mounting of parts to the casings of them.
